"Misterija Satoši - Poreklo bitkoina" je francuski dokumentarno-animirani serijal koji dešifruje unutrašnje funkcionisanje bitkoin revolucije, dok istražuje identitet njenog tvorca.

Prvu decentralizovanu i pouzdanu kriptovalutu – bitkoin, osnovao je Satoši Nakamoto 3. januara 2009. godine. On je nestao 2011. i od tada ostaje anoniman, a njegov identitet je predmet svakakvih spekulacija. Tokom poslednjih 12 godina, vrednost bitkoina je porasla sa 0,001 na 69.000 dolara. Svi, od vlada do velikih korporacija, zainteresovali su se za Satošijev izum. Ko je Satoši Nakamoto? Kako je njegov izum postao toliko popularan? Šta nam bitkoin govori o svetu u kome živimo?

Ovaj serijal se prikazivao na Radio-televiziji Srbije (RTS 3) u sklopu novogodišnjeg muzičkog i filmskog programa 2022/2023. godine.

Planting new sod sounds simple. Lay it down, water it, done. Nah. That’s just half the story. Mess up the basics, and your lawn turns patchy or yellow within days. Below are some key mistakes folks make – most don’t even realise it till the grass starts dying. Avoid these, or all that Bermuda grass, Zoysia, or St. Augustine sod you paid for? Wasted.

Not Watering Enough (Or Too Much)

Watering is weirdly tricky. Some think you flood it, some sprinkle it once and call it good. Both? Wrong.

New sod needs moisture constantly for the first few weeks. Not just surface wet, but soaked down to where roots gonna grow. If it dries out, even a day or two, them roots shrink back. That leads to shrinkage gaps, brown edges, even whole squares drying up.

Now the flip side? Overwatering. It ain’t about turning your lawn into a swamp. Too much water drowns roots, they rot, and fungus loves soggy grass. Mushrooms pop up, blades turn pale. And once fungus spreads, getting it out’s a pain. Set a timer. Early morning’s best. Avoid watering at night unless you wanna feed mold.

Also, different sod types need different water levels. Zoysia sod ain’t thirsty like St. Augustine. Use your hand – if it feels squishy, back off. If dry and crumbly, bump it up.

Installing Sod On Bad Soil

Throwing new sod on junk dirt is asking for trouble. Sod’s just skin. If the body (soil) under it’s trash, it won’t stick.

First off, you gotta check the soil pH. Anything too acidic or way too alkaline? Sod roots won’t even grow. You can get soil test kits at garden stores or online, pretty cheap. If the pH ain’t right, use lime or sulfur depending what side you need to fix.

Second, compacted soil is death for sod. If the ground’s hard like a sidewalk, roots can’t go down. You need to aerate or till the soil before laying sod. Mix in some compost or sand depending on drainage needs. Make it loose but not fluffy.

Last part? Level the area. Don’t leave holes or slopes. Uneven spots collect water, or the sod don’t touch dirt properly. When air pockets form under the sod, roots dry out fast.

Skipping Starter Fertilizer

You ever tried starting a car with no fuel? That’s your sod without a starter fertilizer. It’s gotta eat.

New sod needs phosphorus-heavy fertilizer to encourage root growth. Problem is, most people either skip it, or throw on the wrong one. A high-nitrogen fertilizer will just make it look green for a week, but the roots? Weak and lazy.

Use something like 10-10-10 or 15-15-15 starter blends. Look for one that’s labeled for new sod or turf establishment. Apply it right before or during laying the sod. Water it in so it doesn’t just sit there on top.

Also, don’t keep feeding every few days thinking more is better. Too much burns the grass. After first application, wait at least 3–4 weeks before reapplying anything. Stick to what the sod variety needs – Bermuda feeds different than Fescue.

If you’re in Texas or southern regions, the soil’s usually nutrient-poor, especially in clay zones. Don’t ignore that. Local extension offices often got free guides for your area.

Mowing Too Soon (or Way Too Late)

Mowing sounds harmless. Grass too tall? Cut it. Simple, right? Not really.

Cut too early? You slice off the tops before roots even grab the soil. That’ll rip the sod clean out. Like tearing bandages off fresh scabs. Usually, wait 10–14 days after laying sod before mowing. Always check if the sod’s rooted. Tug on a corner. If it lifts? Wait.

Other side of the coin – waiting forever. If your new sod grows tall and thick, it blocks sunlight from reaching the base. That leads to thinning, disease, even weeds moving in. Keep it under control.

Big tip – never cut more than one-third of the grass height in one mow. It shocks the sod, stunts growth. And dull mower blades? Slice and tear instead of clean cuts. That opens wounds for pests and fungal infections.

If it’s St. Augustine grass, you’ll mow it higher – around 3.5 inches. Zoysia or Bermuda grass? Lower, closer to 1.5 or 2 inches. Know your grass type or risk killing it one mow at a time.

Not Rolling the Sod After Install

This one? Almost always skipped. And it kills your sod quietly.

When sod’s not rolled, air gaps stay between the grass and dirt. You won’t see it, but the roots? They ain't touching soil good. No contact = no growth. That’s how sod turns yellow even when you watering perfect.

A lawn roller, filled with water, presses sod down evenly. It pushes the roots into soil and gets rid of air pockets. Do it once right after laying sod. If you miss this step, that nice new lawn can turn patchy in under a week.

Don’t worry about crushing it – the roller’s weight is perfect. You ain't smashing it like concrete. Just a good firm press. If you don't have a roller? Rent one from local garden centers, or even Home Depot. Cheap insurance for hundreds of bucks worth of new sod.

Another problem from not rolling: uneven lawn. It looks bumpy, grows uneven, and mowing becomes a chore. Roller fixes that early. Less headache later.

By John "Potato Jack" LeFebvre

The cold, cold air of the morning tickled the nose of Christmas Goat as he lay quietly in bed, just waking up.

The cold air of the morning whispered in the ear of Christmas Goat; it whispered:- icicle secrets!

The moon, round and white, with swirling breezes, made Christmas Goat’s bedroom look like milk.

That reminded Christmas Goat – "It’s time to milk my cows!"

Christmas Goat peeled away the bed sheet and four blankets which kept him warm at night, and sitting on the edge of the bed he put on his gumboots.

He walked out of his bedroom and bumped into a wall because he was still a bit tired. He stood out on his front verandah and looked at the farm. "Come on you cows! It’s time for milking!!" he yelled.

The cows made a quiet line and walked, one behind the other, off to the milking sheds…

..all except for two cows who Christmas Goat had to throw a few potatoes at: then they got moving.

In the shed, the moos filled the air. Christmas Goat made his way past steaming cow flops carrying a bucket and a small stool.

He sat down next to Harry the cow.

"Ready for milking?", he asked.

"Yes, but you should have given me a girls name," said the cow.

"Oh well", said Christmas Goat, "here we go".

"Okay" said the cow, so Christmas Goat grabbed her teats with both hands and made the squirty milk goosh into the bucket.

"How are the kids?" asked Christmas Goat.

"Oh not bad," said Harry. "Bruce is in school and Terry’s just learning to moo."

"Yes, they’re good cows," said Christmas Goat.

"They are" said Harry. "I just wish you hadn’t given them boy’s names."

"Oh well," said Christmas Goat.

Christmas Goat milked all the cows one by one, and then he said to himself, "I think I’ll make myself a hot coffee". Back inside, he turned on the radio, and stirred the coffee powder into the hot water. Yum, he thought, pouring the cow’s milk on top. "Yum Yum Yum".

Christmas Goat drank all of this hot coffee and then made toast. A bird landed on his window sill and said "tweet tweet, tweet tweet ¯ ".

"Tweet tweet " said Christmas Goat".

The telephone rang four times and Christmas Goat picked it up.

"Hello, this is Christmas Goat?"

"Hello Christmas Goat? I’ve been a good goat all year and can you tell me what I’m getting for Christmas?"

"Christmas is tomorrow," said Christmas Goat.

"I know, but … - please tell me, just this once ..!"

"All right little goatgirl, what’s your name?"

"My name is Brenda," said the little girlgoat.

"Let me look at my list here…" said Christmas Goat. "

"Hmmm…" He moved his papers around.

"Are you still there?" asked the little goatgirl.

"Aha!! Yes I’m still here. I’ve just found your name on the list Brenda, here it is. Let’s see, oooh!"

"What is it! Wot is it!"

"It’s a …." But then Christmas Goat stopped talking.

"Why have you stopped talking?" said Brenda, panicking.

"Now, now," said Christmas Goat, "I just remembered it’s a secret."

"A secret!" said Brenda.

"Yes," said ChristmasGoat. "It has to be a surprise."

"No! Tell me now!" said Brenda.

Christmas Goat made a whistling sound with his lips. And then he hung up the phone.

By hanging up the phone like that, Christmas Goat felt a bit rude. But Brenda was rude first, he thought. Meanwhile, Brenda was at home, crying.

Christmas Goat thought , " I better go to see Brenda and explain to her why Christmas has to be a surprise." He went to the garage, oiled the wheels of his cart, and tied up a couple of humans.

"Good humans!" he said as they pulled him out of the garage down the street. The two people pulled the cart steadily along, steam pluming their foreheads.

It was a cold morning, and yet ChristmasGoat knew the earth was a round huge ball that spun on it’s axis while being invisibly dragged around a gigantic non stop fire- "the sun" – and that soon, because of this axis-spin, his part of the world would be receiving increasingly direct sun rays and it would get warm, so he didn’t worry . He explained this to the two men pulling his cart as it rolled through the suburbs, but they just blinked.

After a while, they arrived at Brenda’s house, and Christmas Goat tied the two men to a post and gave them a bottle of beer. Christmas Goat walked up the driveway, up the stairs, and went "knock kn0ck knock". A goat came to the door.

"Hallo Brenda?"

"No I’m Brenda’s brother. Brenda’s in her room, crying."

"Rats," said Christmas Goat.

There was Brenda, covered in tears, sitting on her carpet. Christmas Goat came in and sat down.

"Why did you make me sad?" said the little goatgirl.

"Well," said Christmas Goat, "I really didn’t want to do that. Every year, thousands of little goats ask me ‘what am I getting for Christmas,’ and every time I have to say to them, ‘you’ll see on Christmas day.’ And I Have to say this, I can’t say anything else, that’s just the way Christmas is."

"Come on, you must be able to tell me something a little deeper than (sniff) that."

Oh," said Christmas Goat, "you want the Big Reality explanation.."

"Yes," said Brenda, pouting and looking up from hurt eyes.

"Well," said Christmas Goat, "think what the world would be like with no surprise."

"Why? What would the world be like without surprise?" asked Brenda.

"Utterly predicable, " said Christmas Goat.

"What does predickable mean?" asked Brenda.

"In this case, it means ‘always knowing what’s going to happen’," said Christmas Goat.

"That sounds great!" said Brenda.

"Not really," said ChristmasGoat. "Think about it. Every day you wake up, you know what to wear, you know what’s going to be for breakfast, you know what job you have to go to, you know when it starts, you know how to get there, you know what you will see on the way, you know when you will stop for lunch, you know when you will finish, you know what’s for dinner, by looking at the program, you know what’s on T.V that night, they tell you what the weather will be like tomorrow, you know that if you …"

"That sounds Great!!" butted in Brenda.

"Yeah it sounded great to humans once, too, when they ruled the world. Woops."

"What was that?" said Brenda.

"What was what?" asked Christmas Goat.

"That thing you said, " said Brenda.

"I can’t remember, " said Christmas Goat, although now the shoe was on the other hoof.

"Well I remember, " said Brenda. "It just shocked me, that’s all. You said ‘when humans ruled the world.’"

"You’re right," sighed Christmas Goat. "That’s what I said..

Maybe we can forget about it though?"

Tell me tell me tell me tell me tell me tell me tell me tell me tell me tell me tell me tell me tell me tell… "

"ALL-RIGHT" said Christmas Goat, giving in. "Are you sure you want this dark knowledge?"

"Yes, I’m sure," said Brenda dribbling with excitement.

"Right, well once upon a time, the humans, like those two hitched up to the post outside drinking beer, were our masters. What they said, went."

"Boy," said Brenda.

"That’s right," continued Christmas Goat. "In fact they were the kings of the world. Us goats were treated horribly at times."

"What happened?" asked Brenda the little goatgirl.

"Those people became so set in their ways that they became stale. Nearly every effort at becoming the rulers made them and their lives boring. They thought they knew everything."

"People don’t know anything!" said Brenda.

"Not now they don’t," said Christmas Goat. "But they did in a distant past. Unfortunately they made the mistake of killing most surprises, and that’s when we snuck up them."

"Us goats?"

"Yep."

"And now we’re the kings and queens!" said Brenda gleefully.

"Of course," said Christmas Goat. "But we mustn’t let ourselves get trapped by prediction. That’s why I’m Christmas Goat. It’s my job to make sure surprise is still big in our lives, especially at this time of the year, Christmas." "Thankyou for telling me that true story," said Brenda. "I look forward to my surprise present tomorrow morning."

"That’s a good boy," said Christmas Goat.

"I’m a girl," said Brenda.

That night, Christmas Goat tied up his strongest humans who hauled and heaved his sleigh-cart all over the world through beautiful bright darkness. Kind Mummy and Daddy goats left a snack for Christmas Goat, and beer for the sweaty humans.

Christmas Goat and his team finished delivering the presents just in time.

"Good humans," he said, patting his helpers and switching on the T.V for them.

When Brenda woke up, there was a terrific colourful ping pong ball under her Christmas Tree.

"That is a surprise," smiled Brenda. "I’m a netballer!"

@ 8d34bd24:414be32b

What does it say about us that believers don’t listen as well as unbelievers? Let’s investigate some scripture verses and see what we can discover.

An Object Lesson:

Jesus warned His disciples several times that He would be killed and rise from the dead on the third day. Right after Jesus asked them who they thought He was and Peter replied that He was the Christ (Messiah), Jesus told them what would happen.

From that time Jesus began to show His disciples that He must go to Jerusalem, and suffer many things from the elders and chief priests and scribes, and be killed, and be raised up on the third day. (Matthew 16:21)

We know the disciples heard and understood what Jesus was saying because Peter immediately rebuked Jesus.

Peter took Him aside and began to rebuke Him, saying, “God forbid it, Lord! This shall never happen to You.” But He turned and said to Peter, “Get behind Me, Satan! You are a stumbling block to Me; for you are not setting your mind on God’s interests, but man’s.” (Matthew 16:22-23)

You’d think that Peter would have this moment locked in his mind after being rebuked so harshly for questioning Jesus’s prediction of what would happen.

A while later, Jesus again told His disciples what was about to happen.

And while they were gathering together in Galilee, Jesus said to them, “The Son of Man is going to be delivered into the hands of men; and they will kill Him, and He will be raised on the third day.” And they were deeply grieved. (Matthew 17:22-23)

They again heard what was said because they were “deeply grieved.” They didn’t like what they heard.

Then a third time, as they were approaching Jerusalem, He made certain they knew what was coming:

As Jesus was about to go up to Jerusalem, He took the twelve disciples aside by themselves, and on the way He said to them, “Behold, we are going up to Jerusalem; and the Son of Man will be delivered to the chief priests and scribes, and they will condemn Him to death, and will hand Him over to the Gentiles to mock and scourge and crucify Him, and on the third day He will be raised up.” (Matthew 20:17-19)

The disciples should have known that Jesus’s crucifixion and death were not the end. He told them repeatedly that He would die and be raised from the dead on the third day. They should have been diligently waiting with expectation, but instead they immediately hid, gave up, and headed back to their old lives.

His female followers still cared enough to try to prepare Jesus’s body for burial, but even they did not expect Him to rise as He said.

The angel said to the women, “Do not be afraid; for I know that you are looking for Jesus who has been crucified. He is not here, for He has risen, just as He said. Come, see the place where He was lying. Go quickly and tell His disciples that He has risen from the dead; and behold, He is going ahead of you into Galilee, there you will see Him; behold, I have told you.” (Matthew 28:5-7) {emphasis mine}

Even when the woman came and told the disciples that they had seen Jesus as He had said, none believed them, although Peter and John did have a glimmer of hope and went to look for themselves.

In contrast, the Pharisees, the very people who hated Jesus so much that they fought to have Him crucified, remembered Jesus’s statements.

Now on the next day, the day after the preparation, the chief priests and the Pharisees gathered together with Pilate, and said, “Sir, we remember that when He was still alive that deceiver said, ‘After three days I am to rise again.’ Therefore, give orders for the grave to be made secure until the third day, otherwise His disciples may come and steal Him away and say to the people, ‘He has risen from the dead,’ and the last deception will be worse than the first.” Pilate said to them, “You have a guard; go, make it as secure as you know how.” And they went and made the grave secure, and along with the guard they set a seal on the stone. (Matthew 27:62-66) {emphasis mine}

The Pharisees acted in response to Jesus’s claims. The disciples ignored or forgot Jesus’s claims.

KNOW:

How often do we ignore or forget Jesus’s promises? How often do we despair when we should hold tightly to the promises given to us in the Bible? Are there times that our opponents, unbelievers, are better at quoting the Bible back at us than we are at using the Bible to defend the truth and our faith?

but sanctify Christ as Lord in your hearts, always being ready to make a defense to everyone who asks you to give an account for the hope that is in you, yet with gentleness and reverence (1 Peter 3:15)

We need to know God’s word so we can “give an account for the hope that is in” us. First we need to read the whole Bible. We can’t know who God is, what He has done, and what He commands for us without knowing God’s word.

After we have gotten the big picture by reading through the Bible once, we need to really get to know it well. This not only includes reading the Bible continually, but also include memorizing key verses, so we can bring them to remembrance when we need them.

Some people can repeat a verse multiple times and just know it. Some of us have trouble memorizing things. We have to go to extraordinary measures to memorize God’s word. Some techniques I have used:

• WHITEBOARD APPROACH:

• Write the verse on the white board.

• Read out loud.

• Erase one word. (You can underline where the word is if that helps you remember that a word goes there)

• Read out loud saying verse including missing word.

• Continue erasing words, one at a time, saying the verse until all of the words are gone.

• I haven’t used it personally, but Verse Locker was recommended by another substacker and seems to use a similar technique.

• MUSICAL VERSES:

• Make up a tune and sing the verse or put the verse to a tune you already know.

• If you aren’t good at making up songs, there are sites that have verses to songs, but I haven’t used them personally other than a few from Awana years ago.

• FIRST LETTER:

• Write down the first letter of each word of the verse you want to memorize This gives hints and helps you not accidentally miss words.

• I’ve also made a necklace (it was supposed to be a bracelet, but the verse, 1 Peter 3:15 above, I picked was too long) made of beads with the letters of the words of the verse. By wearing it, you have a reminder to memorize and rememorize the verse till it sticks stronger.

• This is my version of 1 Peter 3:15

  

• APPS:

• There are multiple apps that can help you memorize verses. 5 Best Bible Memory Apps for 2025

We are all different and have different learning styles. Pick the version that works best for you, but be intentional. For so long I wasn’t. Having a child with Down Syndrome in Awana who needed help led me to finding ways to help him and me to memorize the hundreds (or thousands) of verses that are required to finish the program. Keep in mind that you need to keep reviewing them or the memories will fade. The more times you memorize the verse, the longer it will stick with you. You just never know when you will need a Scripture verse and you may not have your Bible or phone (with Bible app) handy.

APPLY:

Knowing the Bible is critical for the Christian life, but knowing the Bible and God’s commands is not enough. We have to live according to this knowledge. We have to apply it in our lives. It needs to change the way we view the world and change the way we live our lives and interact with others.

for it is not the hearers of the Law who are just before God, but the doers of the Law will be justified. (Romans 2:13) {emphasis mine}

Our faith needs to be exhibited through action.

But someone may well say, “You have faith and I have works; show me your faith without the works, and I will show you my faith by my works.” (James 2:18) {emphasis mine}

There is nothing we need to do to be saved besides believe, but if we have saving faith, we should desire God’s word like the author of Psalm 119. Our lives should also change to be conformed to Jesus.

And do not be conformed to this world, but be transformed by the renewing of your mind, so that you may prove what the will of God is, that which is good and acceptable and perfect. (Romans 12:12) {emphasis mine}

There must be works as evidence of our faith.

You believe that God is one. You do well; the demons also believe, and shudder. But are you willing to recognize, you foolish fellow, that faith without works is useless? Was not Abraham our father justified by works when he offered up Isaac his son on the altar? You see that faith was working with his works, and as a result of the works, faith was perfected; (James 2:19-22) {emphasis mine}

The disciples heard Jesus tell them what was going to happen to Him. They knew what He had said because they reacted to it negatively. The problem was they didn’t believe it and didn’t live according to Jesus’s plain words. As important as it is to read and understand the Bible, none of that matters if we don’t believe it and live it.

But I Can’t Do It Myself:

Jesus knew that we could not know and do what we were commanded to know and do, at least not in our own power.

Then He opened their minds to understand the Scriptures, and He said to them, “Thus it is written, that the Christ would suffer and rise again from the dead the third day, and that repentance for forgiveness of sins would be proclaimed in His name to all the nations, beginning from Jerusalem. You are witnesses of these things. And behold, I am sending forth the promise of My Father upon you; but you are to stay in the city until you are clothed with power from on high.” (Luke 24:45-49)

Jesus not only sent the disciples (and all believers) out into the world to tell of what He has done for us, but He told the disciples to “stay in the city until you are clothed with power from on high.” Jesus told them to wait until they had received the Holy Spirit to guide and empower them in the work He had designed them to complete. We also have the Holy Spirit to change our hearts and minds, so we can fulfill the commandments and plans He has for us.

I’m sorry if this post had a little too much overlap with my last post, but knowing God’s word has become a passion of mine and it is where I felt led to go.

May the God of Heaven give you a hunger for His word, help you to understand His word, believe His word, and live His word. May your understanding of the word of God guide you in everything you think, speak, and do. May you never doubt God’s word or discount God’s word because it isn’t according to your preference. God bless you and keep you.

Trust Jesus.

Bitkoin, kao jedinstvena digitalna valuta, postaje poznat široj javnosti u trenutku kada se pojavljuju prvi znaci svetske ekonomske krize a postojeći finansijski sistem počinje da pokazuje sve svoje slabosti. Danas, bitkoin, izaziva veliku pažnju svojim naglim skokovima i padovima.

Osnovna ideja o o decentralizovanim valutama potekla je od osnivača kripto-pank pokreta, među kojima su bili direktori kompanija naprednih tehnologija, univerzitetski profesori i istraživači iz oblasti matematike i fizike. Njihova ideja zasnovana je na anonimnoj, istovremenoj komunikaciji koja neće biti kontrolisana i nadgledana od neke treće strane u procesu.

Šta je kriptovaluta, ko je njen tvorac, kako do nje doći, kako trgovati i gde je čuvati, neka su od pitanja za čijim odgovorima tragamo u emisiji.

Sagovornici u emisiji su svi oni koji su u poslednjih godinu dana bili relevantni učesnici priča o kriptovaluti u Srbiji: osnivači Asocijacije bitkoin, predstavnici Narodne banke Srbije i predstavnici medija.

🧠Quote(s) of the week:

'Bitcoin is a high-IQ, low-time-preference asset in a world addicted to DoorDash, dopamine, and debt. Holding Bitcoin requires patience, conviction, and the ability to not panic when CNBC tells you it’s dead for the 47th time. That rules out, oh, I don’t know - 95% of the population? This isn’t some egalitarian revolution. This is a cognitive filter disguised as a monetary network. The rich, the strategic, the elite - those who understand volatility as an opportunity - will stack the hardest asset on Earth while the masses beg for interest rate cuts and $600 stimmies to buy groceries they can't afford.

It's not a level playing field. It's a time-preference war, and Bitcoin is the scoreboard. And every cycle, we watch it happen again. The media ridicules it, the politicians fear it, and the smart money buys more. While fiat punishes savers and rewards financial nihilism, Bitcoin inverts the whole structure. It’s a vault for those who can delay gratification, think generationally, and understand that true wealth is preserved rather than printed. The game isn’t rigged. It’s just calibrated for adults.' - Adam Livingston

'Bitcoin is an extremely simple thesis. If you think governments will stop debasing and debanking: number go down. If you think they won’t stop debasing and debanking: number go up'- Alex Gladstein

Something to ponder on.

On the 28th of April:

➡️Hunter Horsley: 'Bitcoin at $94k, yet — Google searches for "Bitcoin" near long-term lows. This hasn't been retail-driven. Institutions, advisors, corporations, and nations have come into the space. The types of investors buying Bitcoin are expanding.'

➡️Daniel Batten: 'Cambridge has just released their updated report on Bitcoin mining. For the first time, their report shows that most (52.4%) of the Bitcoin network is now powered by zero-emission energy sources (up from 37% in their last report).

Here's a summary of their findings:

➡️The Bitcoin hashrate has already surged over 17% since the start of the year.

➡️'This shattered a major myth for me: gold production isn’t slowing down—it’s accelerating. According to NYDIG, annual gold mining has been steadily increasing over time, about 1.6% per year, thanks to better extraction technology. In fact, 2024 saw a 1% year-over-year increase, setting an all-time high in gold output (World Gold Council). So why do so many still believe the outdated narrative that gold is becoming harder to find? The truth is: gold is effectively unlimited in supply—we just get better at digging it up. If that surprises you, you're probably not nearly bullish enough on Bitcoin.' - Robert Hefner https://i.ibb.co/JWCHndQk/Gpu-W9-R1-Xw-AAiy-Cv.jpg

When the debt bubble collapses, only sound money with zero counterparty risk matters. Currently, sound money is less than 5% of debt money, and Bitcoin is so tiny it is barely visible on the chart. Stay humble and keep stacking.' https://i.ibb.co/QF0Vf9k8/Gpu-CCIWa-YAAng1-U.png

On the 2nd of May:

➡️ Regarding the whole OP_Return debate.

Grok: ++Key Points: ++ * The OP_RETURN debate in Bitcoin centers on whether its blockchain should store data beyond financial transactions, with ongoing controversy. * It began in 2010 with concerns about blockchain bloat, intensified in 2014 with the "OP_Return Wars," and continues today. * Research suggests the debate reflects a balance between Bitcoin's monetary purpose and potential for broader applications like Dapps. * Compromises, like setting a 40-byte limit in 2014, aimed to address concerns but didn't fully resolve tensions, influencing platforms like Ethereum.

++Background++ OP_RETURN is a Bitcoin script opcode allowing small data storage in transactions, useful for timestamping or Dapps, but raising concerns about blockchain bloat.

++Historical Context++

The debate started in 2010 with the BitDNS proposal, where Satoshi Nakamoto worried about scalability, leading to Namecoin. It peaked in 2014 with Counterparty's use, leading to a 40-byte limit compromise, later adjusted to 83 bytes by 2016.

++Recent Developments++ By 2018-2019, high OP_RETURN usage (20% of transactions) sparked fee debates, but usage has since declined, though data remains, with recent 2023 controversies over size limits.

If you are interested in Bitcoin, then you should check out the following video.

Great video from @GrassFedBitcoin explaining the current OP_RETURN situation. The choice isn’t between bloating the UTXO set or increasing OP_RETURN, it’s whether we normalize spam or we reject it. Is Bitcoin for data storage or financial transactions? https://www.youtube.com/watch?v=15biQH1H140 Every Bitcoiner needs to see this! Vires in Numeris.

A great counterargument by Seth for Privacy:

https://x.com/sethforprivacy/status/1919003009880616976

Personally, I tend to agree with Seth.

To sum it up:

If you are running a node, you should switch from Core to Knots immediately. It's very straightforward, and you don't need to redo the initial block download.

If you arent running a node you are a leech and need to get your shit together.

➡️Tether CEO defends skipping MiCA, calling EU stablecoin rules “very dangerous.” Ardoino: “The European Central Bank is more interested in pushing the digital euro to control people and how they spend their money.”

On the 3rd of May:

➡️Arizona Governor Katie Hobbs has vetoed the state’s Strategic Bitcoin Reserve legislation after it was passed by the House and Senate. She states: “Arizonans’ retirement funds are not the place for the state to try untested investments like virtual currency.”

Apparently, the Arizona State Retirement System already holds 53,097 shares of MSTR. You can’t make this shit up.

➡️Vitalik Buterin: 'One of the best things about Bitcoin is how simple it is. This simplicity has lots of benefits. Let's bring those benefits to Ethereum.' Almost like Bitcoin is eh......(checks notes)......better tech. Just use Bitcoin, dumbfuck! 'It's only taken a decade, but Ethereum's creator is having an inkling that he never should have created Ethereum, which destroyed billions of precious capital and instead focused on Bitcoin.' - Vijay Boyapati

There is no second best!

On the 4th of May:

➡️Eli Nagar:

Heads up, Bitcoin holders: The EU will ban anonymous crypto accounts by July 2027. Every transaction above €1,000 will need your ID. Privacy is becoming extinct. Every new restriction is a marketing campaign for Bitcoin. “Hi, we’re the EU. We’ll surveil you, control your money, and criminalise privacy.” By doing that, they have decided to help promote the black market...great work, EU! Oh, and remember, the EU can't ban what it has no control over: hold your own private keys.

➡️Cumulative inflows into the Bitcoin ETFs have hit a fresh ATH of $ 40.62 B.

On the 5th of May:

➡️Brown University invested $4.9M in Bitcoin via BlackRock's IBIT, as disclosed in a recent SEC filing. The university owns 105K IBIT shares ($5.8M), 2.3% of Brown's reported $216M equity holdings.

➡️Strategy acquires 1,895 BTC for $180.3 million at an average price of $95,167 per bitcoin. As of May 4, 2025, they hold 555,450 BTC acquired for $38.08 billion at an average price of $68,550 per bitcoin.

Past week summary

From a Self Custody for Organizations perspective, after analyzing the existing protocols (Cerberus, 10xSecurityBTCguide and Glacier) and reading a bunch of relates articles and guides, have wrapped to the conclusion that this format it is good to have as reference. However, something else is needed. For example, a summary or a map of the whole process to provide an overview, plus a way to deliver all the information and the multy-process in a more enjoyable way. Not a job for this hackathon, but with the right collaborations I assume it's possible to: - build something that might introduce a bit more quests and gamification - provide a learning environment (with testnet funds) could also be crucial on educating those unfamiliar with bitcoin onchain dynamics.

Have been learning more and playing around practicing best accessibility practices and how it could be applied to a desktop software like Bitcoin Safe. Thanks to @johnjherzog for providing a screen recording of his first experience and @jasonb for suggesting the tools to be used. (in this case tested/testing on Windows with the Accessibility Insights app). Some insight shared have been also applied to the website, running a full accessibility check (under WCAG 2.2 ADA, and Section 508 standards) with 4 different plugins and two online tools. I recognize that not all of them works and analyze the same parameters, indeed they complement each other providing a more accurate review.

For Bitcoin Safe interface improvements, many suggestions have been shared with @andreasgriffin , including: - a new iconset, including a micro-set to display the number of confirmed blocs for each transaction - a redesigned History/Dashboard - small refinements like adding missing columns on the tables - allow the user to select which columns to be displayed - sorting of unconfirmed transactions - Defining a new style for design elements like mempool blocks and quick receive boxes You can find below some screenshots with my proposals that hopefully will be included in the next release.

Last achievement this week was to prepare the website https://Safe.BTC.pub, the container where all the outcomes f this experiment will be published. You can have a look, just consider it still WIP. Branding for the project has also been finalized and available in this penpot file https://design.penpot.app/#/workspace?team-id=cec80257-5021-8137-8005-eab60c043dd6&project-id=cec80257-5021-8137-8005-eab60c043dd8&file-id=95aea877-d515-80ac-8006-23a251886db3&page-id=132f519a-39f4-80db-8006-2a41c364a545

What's for next week

After spending most of the time learning and reading material, this coming week will be focused on deliverables. The goal as planned will be to provide: - Finalized Safe₿its brand and improve overall desktop app experience, including categorization of transactions and addresses - An accessibility report or guide for Bitcoin Safe and support to implement best practices - A first draft of the Self-Custody for Organizations guide/framework/protocol, ideally delivered through the website http://Safe.BTC.pub in written format, but also as FlowChart to help have an overview of the whole resources needed and the process itself. This will clearly define preparations and tools/hardwares needed to successfully complete the process.

„Ova mašina ozelenjava“, koji predstavlja Swan Bitcoin, je dokumentarac koji istražuje složen i nijansiran odnos između Bitkoina i energije. Producent filma je Enrike Pozner, dok je režiser nagrađivani britanski filmski stvaralac Džejmi King čija je serija „Ukradi ovaj film“ (2006–2010) bila jedan od najpreuzimanijih dokumentaraca svih vremena.

U filmu „Ova mašina ozelenjava“ učestvuje glavna ekonomska savetnica Swan-a Lin Alden zajedno sa Aleksom Gladstajnom, Nikom Karterom i mnogim drugima. „Ova mašina ozelenjava“ razbija mnoge zablude o rudarenju Bitkoina i iznosi ubedljive argumente za Bitkoin kao neto-pozitivan faktor za životnu sredinu.

Information ohne Reflexion ist geistiger Flugsand. \ Ernst Reinhardt

Der lateinische Ausdruck «Quo vadis» als Frage nach einer Entwicklung oder Ausrichtung hat biblische Wurzeln. Er wird aber auch in unserer Alltagssprache verwendet, laut Duden meist als Ausdruck von Besorgnis oder Skepsis im Sinne von: «Wohin wird das führen?»

Der Sinn und Zweck von so mancher politischen Entscheidung erschließt sich heutzutage nicht mehr so leicht, und viele Trends können uns Sorge bereiten. Das sind einerseits sehr konkrete Themen wie die zunehmende Militarisierung und die geschichtsvergessene Kriegstreiberei in Europa, deren Feindbildpflege aktuell beim Gedenken an das Ende des Zweiten Weltkriegs beschämende Formen annimmt.

Auch das hohe Gut der Schweizer Neutralität scheint immer mehr in Gefahr. Die schleichende Bewegung der Eidgenossenschaft in Richtung NATO und damit weg von einer Vermittlerposition erhält auch durch den neuen Verteidigungsminister Anschub. Martin Pfister möchte eine stärkere Einbindung in die europäische Verteidigungsarchitektur, verwechselt bei der Argumentation jedoch Ursache und Wirkung.

Das Thema Gesundheit ist als Zugpferd für Geschäfte und Kontrolle offenbar schon zuverlässig etabliert. Die hauptsächlich privat finanzierte Weltgesundheitsorganisation (WHO) ist dabei durch ein Netzwerk von sogenannten «Collaborating Centres» sogar so weit in nationale Einrichtungen eingedrungen, dass man sich fragen kann, ob diese nicht von Genf aus gesteuert werden.

Das Schweizer Bundesamt für Gesundheit (BAG) übernimmt in dieser Funktion ebenso von der WHO definierte Aufgaben und Pflichten wie das deutsche Robert Koch-Institut (RKI). Gegen die Covid-«Impfung» für Schwangere, die das BAG empfiehlt, obwohl es fehlende wissenschaftliche Belege für deren Schutzwirkung einräumt, formiert sich im Tessin gerade Widerstand.

Unter dem Stichwort «Gesundheitssicherheit» werden uns die Bestrebungen verkauft, essenzielle Dienste mit einer biometrischen digitalen ID zu verknüpfen. Das dient dem Profit mit unseren Daten und führt im Ergebnis zum Verlust unserer demokratischen Freiheiten. Die deutsche elektronische Patientenakte (ePA) ist ein Element mit solchem Potenzial. Die Schweizer Bürger haben gerade ein Referendum gegen das revidierte E-ID-Gesetz erzwungen. In Thailand ist seit Anfang Mai für die Einreise eine «Digital Arrival Card» notwendig, die mit ihrer Gesundheitserklärung einen Impfpass «durch die Hintertür» befürchten lässt.

Der massive Blackout auf der iberischen Halbinsel hat vermehrt Fragen dazu aufgeworfen, wohin uns Klimawandel-Hysterie und «grüne» Energiepolitik führen werden. Meine Kollegin Wiltrud Schwetje ist dem nachgegangen und hat in mehreren Beiträgen darüber berichtet. Wenig überraschend führen interessante Spuren mal wieder zu internationalen Großbanken, Globalisten und zur EU-Kommission.

Zunehmend bedenklich ist aber ganz allgemein auch die manifestierte Spaltung unserer Gesellschaften. Angesichts der tiefen und sorgsam gepflegten Gräben fällt es inzwischen schwer, eine zukunftsfähige Perspektive zu erkennen. Umso begrüßenswerter sind Initiativen wie die Kölner Veranstaltungsreihe «Neue Visionen für die Zukunft». Diese möchte die Diskussionskultur reanimieren und dazu beitragen, dass Menschen wieder ohne Angst und ergebnisoffen über kontroverse Themen der Zeit sprechen.

Quo vadis – Wohin gehen wir also? Die Suche nach Orientierung in diesem vermeintlichen Chaos führt auch zur Reflexion über den eigenen Lebensweg. Das ist positiv insofern, als wir daraus Kraft schöpfen können. Ob derweil der neue Papst, dessen «Vorgänger» Petrus unsere Ausgangsfrage durch die christliche Legende zugeschrieben wird, dabei eine Rolle spielt, muss jede/r selbst wissen. Mir persönlich ist allein schon ein Führungsanspruch wie der des Petrusprimats der römisch-katholischen Kirche eher suspekt.

My last article, I wrote about DePIN, a passive income that is easily accessible and something to consider as supplemental income. This week I want to discuss another form of finance. Let’s face it: when most of us hear the word “finance”, our eyes glaze over faster than a donut in a Krispy Kreme factory.

It conjures images of Wall Street suits, casino type crypto scams, and incomprehensible jargon. What if I told you that finance could be regenerative? Could your money heal the world?

Regenerative Finance is what I’m discussing; ReFi if you want to sound cool. Regenerative finance is a movement that’s quietly transforming how we think about money, investment and our collective future. Let’s dive down the rabbit hole and take a journey into a world where your money can make things better.

You’re at a party and someone asks what you do for a living. You say, “I work in sustainable finance.” Boring to most, they politely nod. But what if you said, “I work in regenerative finance. We invest in projects that restore rainforests, rebuild communities and make money while healing the planet.” How interesting, right?

What is sustainable? It is about not making things worse, just sustaining them. On the other hand, regenerative finance restores, renews and improves systems, making sure things are better when you leave than when you arrived.

Regeneration systems imagine every dollar invested helps a forest grow, a community thrive or a river run clear again. Remember sustainability is about keeping things as they are. Regeneration is about making things better.

Here’s a real-world example: The Savory Institute works with ranchers to restore grasslands using holistic grazing. Investors in their projects don’t just avoid harm, they rebuild the soil, increase biodiversity, and capture carbon. That’s money making a difference.

Regenerative finance asks, “How will the investment affect people, planet and profit, not just today, but decades from now?” Another real-world example, Ecosia, the search engine that plants trees, invests profits into reforestation projects worldwide. Their financial model considers long term ecological health, not just quarterly returns.

ReFi isn’t about faceless corporations. It’s about empowering local communities and restoring ecosystems. Think of it as crowdfunding Mother Earth.

How does all this magic happen? Here are a few ways to invest.

IMPACT INVESTING As examples from above, this is where you put your money into projects that actively restore ecosystems, empower communities or fight climate change. FUNDING BONDS These are bonds issued on blockchain platforms to fund sustainable projects. They are managed by smart contracts and investors get digital tokens representing their share. Think about this as an early adopter.

TOKENIZATION This is taking real-world assets and turning them into digital tokens. Think carbon credits. There’s no Wall Street middleman which makes it easier to track, invest and trade in regenerative projects. You can have fractional ownership with tokenization which means easier access to more assets.

Real estate has moved into fractional ownership using tokenization. The threshold to invest has lowered immensely with this practice.

The world is facing some big problems with climate change, inequality, biodiversity loss and I could go on. Traditional finance hasn’t exactly been successful. Regenerative finance offers a new way forward.

By focusing on restoring rather than just sustaining, we create resilient, equitable and thriving systems for future generations. As someone who is 64 years old, I was taught to leave the world better than you found it.

There has been much speculation over the years about the next evolution of the internet and business. How will we adapt? What will financial systems look like?

Let’s look at some projects that are already making a difference: Eden Reforestation Project Employs local communities to plant millions of trees, restoring ecosystems and creating jobs.

บทที่ 3: ตะวันออกแห่งเอเดน (East of Eden)

บทนี้เจาะลึกต้นกำเนิดของโครงสร้างอำนาจในมนุษยชาติผ่านมุมมองเชิงประวัติศาสตร์และเศรษฐศาสตร์ โดยเฉพาะการเปลี่ยนแปลงครั้งสำคัญที่เรียกว่า การปฏิวัติเกษตรกรรม ซึ่งพลิกโฉมวิถีชีวิตมนุษย์จากการเป็นนักล่าสัตว์และเก็บของป่า มาสู่สังคมที่ตั้งถิ่นฐานถาวร สะสมทรัพย์สิน และมีแนวโน้มที่จะใช้ความรุนแรงและจัดองค์กรทางอำนาจที่ซับซ้อนมากขึ้น

การเปลี่ยนผ่านดังกล่าวสามารถเห็นภาพได้อย่างคมชัดผ่านสัญลักษณ์ในพระคัมภีร์ไบเบิล จากเรื่องราวของคาอินและอาเบล:

“และพระเจ้าตรัสกับคาอินว่า ‘อาเบล น้องชายของเจ้าอยู่ที่ไหน?’ คาอินตอบว่า ‘ข้าพระองค์ไม่ทราบ ข้าพระองค์เป็นผู้ดูแลน้องชายของข้าหรือ?’ พระเจ้าตรัสว่า ‘เจ้าทำอะไรลงไป? เสียงเลือดของน้องชายเจ้าร้องต่อเรามาจากพื้นดิน’” (ปฐมกาล 4:9-10)

นี่ไม่ใช่เพียงบทสนทนาทางศาสนา แต่สามารถตีความในเชิงสัญลักษณ์ว่าเป็นการบันทึกครั้งแรกของอาชญากรรมที่เกิดจากตรรกะของการเป็นเจ้าของและความรุนแรง คาอิน ผู้เป็น “ชาวนา” ได้สังหารน้องชายของตนเองจากแรงริษยาและการแข่งขันในบริบทของการถวายผลผลิต ความเปรียบเปรยนี้สะท้อนถึงความเปลี่ยนแปลงของตรรกะทางสังคมเมื่อมนุษย์เข้าสู่ยุคเกษตรกรรม

ในยุคก่อนเกษตรกรรม มนุษย์อยู่กันเป็นกลุ่มเล็ก ๆ พึ่งพาทรัพยากรธรรมชาติในพื้นที่กว้าง ไม่มีแรงจูงใจจะใช้ความรุนแรง เพราะไม่มีทรัพย์สินให้แย่งชิง อาหารต้องบริโภคทันที ไม่มีการสะสม ทำให้ไม่มีใครร่ำรวยหรือยากจนอย่างชัดเจน โครงสร้างสังคมจึงเท่าเทียมและร่วมมือกันได้ดี

แต่เมื่อมนุษย์เริ่มเพาะปลูกและเลี้ยงสัตว์ พื้นที่การผลิตอาหารต้องได้รับการดูแลต่อเนื่อง ทำให้ไม่สามารถอพยพหนีภัยได้ง่าย และเมื่อมีผลผลิตมากขึ้น ก็ยิ่งเป็นเป้าหมายของการปล้นสะดม ส่งผลให้กลุ่มนักรบผู้ใช้ความรุนแรงสามารถสะสมทรัพยากรและอำนาจได้มากขึ้น และบางกลุ่มก็พัฒนาเป็นรัฐ ระบบการป้องกันและการเก็บส่วยในรูปแบบของรัฐจึงค่อยๆ ก่อตัวขึ้นจากพันธมิตรระหว่างนักรบกับนักบวช

ทรัพย์สิน ส่วนตัวซึ่งไม่เคยมีความสำคัญในสังคมนักล่าสัตว์ กลายเป็นสิ่งที่จำเป็นในสังคมเกษตรกรรม เพราะไม่มีใครจะเพาะปลูกด้วยแรงงานของตนเองหากรู้ว่าจะถูกปล้นไป ความชัดเจนของกรรมสิทธิ์จึงเป็นสิ่งจำเป็น แต่ขณะเดียวกัน กลไกของความรุนแรงก็ทำให้สิทธิในทรัพย์สินตกอยู่ในความเสี่ยง ระบบของรัฐในยุคแรกจึงเป็นการผูกขาดความรุนแรงในนามของความคุ้มครอง

ในสังคมเกษตรกรรมที่ผลิตภาพต่ำ ผู้คนจำนวนมากต้องพึ่งพารูปแบบการป้องกันทางเศรษฐกิจที่เรียกว่า “หมู่บ้านปิด” ซึ่งความเสี่ยงถูกกระจายระหว่างเจ้าของที่ดินกับชาวนา โดยมีหัวหน้าหมู่บ้านเป็นตัวกลางในความสัมพันธ์ทางเศรษฐกิจ การจ่ายค่าเช่าที่ดินในรูปแบบผลผลิตแทนเงิน ช่วยให้เจ้าของที่ดินและผู้เช่าสามารถรับมือกับภัยพิบัติร่วมกันได้ในปีที่ผลผลิตตกต่ำ

พฤติกรรมหลีกเลี่ยงความเสี่ยงนี้จำกัดการเติบโตและนวัตกรรมในระบบเศรษฐกิจ เนื่องจากโอกาสในการอยู่รอดมีค่าสูงกว่าความหวังต่อความมั่งคั่ง และนำไปสู่การครอบงำของวัฒนธรรมที่กดทับพฤติกรรมแปลกแยก วัฒนธรรมจึงเป็นกลไกปรับตัวที่เหมาะสมกับความแร้นแค้น ไม่ใช่เครื่องมือในการเปิดโอกาส

ในพื้นที่ที่เกษตรกรรมมีผลิตภาพสูง เช่น กรีซโบราณ กรรมสิทธิ์ส่วนตัว การออม และการเลื่อนสถานะทางสังคมก็เริ่มปรากฏ แต่ในพื้นที่ส่วนใหญ่ของโลก ระบบศักดินาครอบงำ เพราะผลิตภาพต่ำและมีความจำเป็นต้องพึ่งพาอำนาจผูกขาดความรุนแรง

บทนี้ยังวิเคราะห์การเปลี่ยนผ่านจากยุคโรมันไปสู่ยุคกลาง โดยเฉพาะ การปฏิวัติศักดินา ราวปี ค.ศ. 1000 การล่มสลายของจักรวรรดิโรมันทำให้รัฐอ่อนแอ และเปิดโอกาสให้ชาวนารายย่อยมีอิสระมากขึ้นในยุคมืด แต่เมื่อประชากรเพิ่มขึ้น ภูมิอากาศแปรปรวน และภัยพิบัติเกิดขึ้นต่อเนื่อง ผลผลิตตกต่ำ ชาวนาไม่สามารถรักษากรรมสิทธิ์ของตนไว้ได้ ต้องมอบที่ดินให้กับผู้มีอำนาจเพื่อแลกกับความคุ้มครอง กระบวนการนี้ค่อย ๆ เปลี่ยนเจ้าของที่ดินรายย่อยให้กลายเป็นไพร่ในระบบศักดินา

กองกำลังติดอาวุธ เช่น อัศวินม้า มีบทบาทสำคัญในการรวมอำนาจ เพราะมีต้นทุนการจัดหาสูงจนชาวนาทั่วไปไม่สามารถแข่งขันได้ โบสถ์จึงเข้ามามีบทบาทในการจำกัดความรุนแรงผ่านขบวนการ สันติภาพของพระเจ้า และยังมีบทบาทในเชิงโครงสร้างอื่น ๆ เช่น การศึกษา การจัดเก็บความรู้ การพัฒนาเกษตรกรรม และการก่อสร้างโครงสร้างพื้นฐาน เช่น ถนน เขื่อน และโรงสี

ตรรกะของความรุนแรงเปลี่ยนไปอย่างสิ้นเชิงในยุคเกษตรกรรม เพราะทรัพย์สินสามารถแย่งชิงได้ มีต้นทุนในการปกป้อง และผลตอบแทนที่คุ้มต่อการลงทุนในอาวุธ ความรุนแรงจึงกลายเป็นสิ่งที่ “คุ้มค่า” ทางเศรษฐศาสตร์เป็นครั้งแรกในประวัติศาสตร์

บทสรุปของบทนี้ชี้ให้เห็นว่า การเปลี่ยนแปลงจากยุคนักล่าสัตว์มาสู่การเกษตรคือจุดเริ่มต้นของระบบอำนาจ และเสรีภาพส่วนบุคคลถูกลดทอนลงเรื่อย ๆ เพื่อตอบสนองต่อความมั่นคงของทรัพย์สิน ในแง่นี้ เรื่องราวของคาอินผู้สังหารน้องชาย ซึ่งเป็นคนเลี้ยงสัตว์ สะท้อนถึงการก้าวเข้าสู่ยุคใหม่ที่การเพาะปลูกไม่เพียงสร้างอารยธรรม แต่ยังเปิดประตูสู่ตรรกะของการใช้ความรุนแรงอย่างเป็นระบบ

For generations before generative text, writers have used the em dash to hop between thoughts, emotions, and ideas. Dickens shaped his morality tales with it, Woolf’s stream-of-consciousness flowed through it, Kerouac let it drive his jazz-like prose. Today, Sally Rooney threads it through her quiet truths of the heart.

---

---

But this beloved punctuation mark has become a casualty of the algorithmic age. The em dash has been so widely adopted by AI-generated text that even when used by human hands, it begs the question: was this actually written or apathetically prompted?

---

---

The battle for the soul of writing is in full swing. And the human fightback starts here. With a new punctuation mark that serves as a symbol of real pondering, genuine daydreaming, and true editorial wordsmithery. Inspired by Descartes’ belief that thinking makes us human, the am dash is a small but powerful testament that the words you’ve painstakingly and poetically pulled together are unequivocally, certifiably, and delightfully your own.

Consider the following two charts from A History of Clojure which detail the introduction and retention of new code by release for both Clojure and for Scala.

While this doesn't necessarily translate to library stability, it's reasonable to assume that the attitude of the Clojure maintainers will seep into the community. And that assumption is true.

Consider a typical Javascript program. What is it comprised of? Objects, objects, and more objects. Members of those objects must be either introspected or divined. Worse, it's normal to monkeypatch those objects, so the object members may (or may not) change over time.

Now, consider a typical Clojure program. What is it comprised of? Namespaces. Those namespaces contain functions and data. Functions may be dynamically generated (via macros), but it is extremely rare to "monkeypatch" a namespace. If you want to know what functions are available in a namespace, you can simply read the source file.

The global financial system is creaking under its own weight. The IMF is urging banks to shore up capital, cut risk, and brace for impact. Basel III is their answer, a last-ditch effort to reinforce a brittle foundation.

But behind the scenes, a quieter revolution is under way.

Bitcoin, the world’s first stateless digital asset, is no longer on the sidelines. It’s entering the Basel conversation: not by invitation, but by inevitability.

Basel III: The System’s Self-Diagnosis

Basel III is more than a technical rulebook. It’s a confession: an admission that the global banking system is vulnerable. Created in the aftermath of 2008, it calls for: • Stronger capital reserves: So banks can survive losses. • Lower leverage: To reduce the domino effect of overexposure. • Liquidity buffers: To weather short-term shocks without collapsing.

But here’s the kicker: these rules are hostile to anything outside the fiat system. Bitcoin gets hit with a punitive 1,250% risk weight. That means for every $1 of exposure, banks must hold $1 in capital. The message from regulators? “You can hold Bitcoin, but you’ll pay for it.”

Yet that fear: based framing misses a bigger truth: Bitcoin doesn’t just survive in this environment. It thrives in it.

Bitcoin: A Parallel System, Built on Hard Rules

Where Basel III imposes “fiat discipline” from the top down, Bitcoin enforces it from the bottom up: with code, math, and transparency.

Bitcoin is not just a hedge. It’s a structural antidote to systemic fragility.

Volatility: A Strategic Asset

Yes, Bitcoin is volatile. But in a system that devalues fiat on a schedule, volatility is simply the cost of freedom. Under Basel III, banks are expected to build capital buffers during economic expansions.

What asset allows you to build those buffers faster than Bitcoin in a bull market?

When the cycle turns, those reserves act as shock absorbers: converting volatility into resilience. It’s anti-fragility in motion.

Liquidity: Real, Deep, and Global

Bitcoin settled over $19 trillion in transactions in 2024. That’s not hypothetical liquidity. it’s real, measurable flow. Unlike traditional high-quality liquid assets (HQLAs), Bitcoin is: • Available 24/7 • Borderless • Not dependent on central banks

By traditional definitions, Bitcoin is rapidly qualifying for HQLA status. Even if regulators aren’t ready to admit it.

Diversification: Breaking the Fiat Dependency

Basel III is designed to pull banks back into the fiat matrix. But Bitcoin offers an escape hatch. Strategic Bitcoin reserves are not about speculation, they’re insurance. For family offices, institutions, and sovereign funds, Bitcoin is the lifeboat when the fiat ship starts taking on water.

Regulatory Realignment: The System Reacts

The Basel Committee’s new rules on crypto exposures went live in January 2025. Around the world, regulators are scrambling to define their stance. Every new restriction placed on Bitcoin only strengthens its legitimacy, as more institutions ask: Why so much resistance, if it’s not a threat?

Bitcoin doesn’t need permission. It’s already being adopted by over 150 public companies, forward-looking states, and a new class of self-sovereign individuals.

Conclusion: The Real Question

This isn’t just about Bitcoin fitting into Basel III.

The real question is: How long can Basel III remain relevant in a world where Bitcoin exists?

Bitcoin is not the risk. It’s the reality check. And it might just be the strongest capital buffer the system has ever seen.

Gradually then suddenly.

Wer sein eigenes Geld abheben möchte, macht sich heute – in Spanien - verdächtig. Wer dort eine größere Geldmenge des eigenen Vermögens abzuheben gedenkt, muss das von nun an Tage zuvor anmelden. Diese neue Regelung lässt sich auch nicht dadurch umgehen, dass man mehrere kleine Einzelbeiträge abhebt. Und die, die die neue Regelung missachten, werden empfindlich bestraft. So gerät jeder, der zu häufig Bares abhebt, in das Visier der Behörden.

Was sich in Spanien an Bankautomaten und -schaltern eingeschlichen hat, könnte sich seinen Weg auch nach Deutschland bahnen. In Frankreich, so zeigt die persönliche Erfahrung, variiert die zu erzielende Geldmenge am Automaten unter noch ungeklärten Bedingungen von Tag zu Tag, von Konto zu Konto. Der Automat gibt vor, ob gerade beispielsweise 60, 200 oder 400 Euro abgehoben werden dürfen.

Davno pre nego što je postala šef najdesnije italijanske vlade od Drugog svetskog rata, Đorđa Meloni je kritikovala ono što je nazvala francuskom „kolonijalnom valutom“.

U snimku italijanske televizije iz 2019. koji je prošlog meseca postao megaviralan, Meloni je optužila Francusku da koristi CFA franak za eksploataciju resursa 14 afričkih zemalja i vrši finansijsku dominaciju nad njima. Određene stvari koje je tvrdila u videu nisu baš tačne, ali CFA franak jeste kontroverzan.

CFA franak je stvoren 1945. da bude valuta „francuskih kolonija u Africi“, a pošto Francuska kontroliše njegovo štampanje i promet, francuska vlada i dalje ima finansijsku kontrolu nad dobrim delom zapadnoafričke zemlje i više od 180 miliona ljudi. Dok su francuski zvaničnici ranije nazivali ovu valutu „činom velikodušnosti prema kolonijama“, o njenoj upotrebi se sada žestoko raspravlja.

Neke od afričkih nacija borile su se protiv valute, uključujući građane koji su razbijali prodavnice povezane sa Francuskom i osuđivali francuski jezik koji se uči u školama.

Jedna od onih 14 afričkih zemalja koja još uvek koristi CFA franak je Centralnoafrička Republika, država bez izlaza na more u kojoj živi oko 5 miliona ljudi i jedna od najsiromašnijih zemalja na svetu.

Ali dok druge afričke nacije razmatraju odbacivanje CFA franka, CAR je jedna od prvih koja je zaista uradila nešto po tom pitanju, a ranije ove godine postala je prva zemlja u Africi i tek druga u svetu koja je usvojila Bitcoin kao legalnu valutu.

„Alternativa gotovini je kriptovaluta“, rekao je predsednik Faustin-Aršanž Touadera. „Za nas formalna ekonomija više nije opcija”.

Dok su prve najave o bitkoinu izazvale konfuziju, međunarodne nesuglasice i reakcije, vlada CAR-a je nastavila sa uvođenjem. Osam meseci kasnije, mnogi ljudi širom sveta, pa čak i građani CAR-a, možda nisu ni svesni da se promena dogodila.

U CAR samo 14 odsto stanovništva ima pristup električnoj energiji, a još manje – oko 10 odsto – može da koristi internet. A konflikt i dalje tinja i negativno utiče na zemlju i njenu ekonomiju već deceniju.

Na predstavljanju bitkoina, vlada CAR-a je rekla da će usvajanje valute promeniti bogatstvo zemlje i staviti CAR „na mapu najhrabrijih i najvizionarskijih zemalja sveta“.

Bitkoin ne kontroliše nikakva moć, tehnički je univerzalno dostupan i ne može se cenzurisati – što je velika promena u odnosu na drugu valutu nacije, ali prosečnom građaninu CAR bi bilo potrebno 60 godina da kupi jedan novčić.

U Bangiju – glavnom gradu CAR – studenti Univerziteta rekli su za VICE da se „ništa nije promenilo“ od velike najave vlade.

Studenti su želeli da ostanu anonimni jer su se plašili da negativno govore o ambicijama vlade. Pravo na slobodu izražavanja ne postoji u CAR, a građani često doživljavaju zastrašivanje i nasilje od strane provladinih milicija, oružanih grupa i snaga nacionalne bezbednosti.

„Bilo je ogromno slavlje kada je objavljen Bitcoin plan i svi smo bili ponosni na našu zemlju“, rekao je jedan 20-godišnjak, „ali ne mislim da se život ovde uopšte poboljšao od tada”.

Drugi student je dodao: „Nigde nema cena u radnjama izraženih u bitkoioni, niti iko traži od ljudi da plaćaju koristeći novu valutu. Većina trgovaca i kupaca na tržištu nemaju telefon ili internet. Posebno ljudi izvan Bangija, nemaju ništa““.

Aleks Lilaher, osnivač i izvršni direktor Rise Up Media – marketinške agencije koja radi sa bitkoin startapima – je saglasan sa studentima, rekavši za VICE koliko je „iznenađen” što je ta zemlja uopšte napravila takavpotez.

„Centralnoafrička Republika nije baš lider u tehnologiji na kontinentu, i činilo se da tamo nikada nije bilo mnogo bitkoin korisnika koji bi mogla da lobiraju za takav potez“, rekao je on.

Upitan da li građani CAR-a treba da vide usvajanje bitkoina kao pozitivnu ili negativnu stvar, Lilaher je odgovorio „ni jedno ni drugo, jer jednostavno ne mogu da vidim da će usvajanje uskoro krenuti. Ali imati alternativu i poslati signal Francuskoj da CAR želi da ima više nezavisnosti od valute je pozitivno u mojim očima”.

Dodaje: „Međutim, to takođe može imati posledice jer postoje moćne institucije poput Međunarodnog monetarnog fonda, na primer, sa kojima CAR mora da se bavi, koje nisu srećne što zemlje usvajaju bitkoin. Dakle, moglo bi doći do izazova sa kojima će vlada morati da se nosi“.

Centralnoafrička Republika je druga zemlja u svetu koja je usvojila bitkoin, a prva je El Salvador u septembru 2021. Lansiranje valute je tamo imalo različite rezultate, a nedavno je opisano kao „antiklimaktično“ i samo ga turisti zaista koriste.

Iako su ljudi možda očekivali da će druge nacije pratiti El Salvador, sigurno ne bi pomislili da će CAR odgovarati računu.

Glavna opoziciona stranka CAR-a bila je protiv tog predloga od samog početka. Banka centralnoafričkih država je takođe nazvala ovaj potez „problematičnim“ i navela da bi usvajanje valute uz CFA moglo ugroziti odnos nacije sa drugim afričkim zemljama.

Čak i kada većina ljudi u CAR-u nije mogla da investira u Bitcoin, i sve poruke upozorenja, u julu je vlada CAR-a lansirala sopstvenu kriptovalutu – „Sangocoin“. Sango je lokalni jezik koji se govori širom zemlje.

Sangocoin neki vide kao budućnost CAR-a, a zahtevao je minimalnu investiciju od 500 dolara. Zauzvrat, investitori su mogli da kupe zemljište u zemlji bogatoj dijamantima za 10.000 dolara, pa čak i da kupe državljanstvo CAR-a za oko 60.000 dolara – iako je ove ponude kasnije blokirao najviši sud zemlje. Sangocoin investitori su takođe trenutno „zaključani“ za kupovinu, bez načina da kriptovalutu prodaju ili razmene.

Bio je to hrabar potez vlade, ali izgleda da se još uvek nije isplatio.

Ovog meseca, Centralnoafrička Republika je saopštila da odlaže puštanje nacionalne kriptovalute na kripto berze – što bi olakšalo međunarodnu trgovinu. Rojters kaže da je vlada okrivila „trenutne tržišne uslove” i „tržišne razloge”, ali je novinska agencija izračunala da je Sangocoin dostigao samo „0,01%” od najnovijeg vladinog cilja prodaje.

Još jedan skeptik je Aleks Gladštajn, glavni strateški službenik Fondacije za ljudska prava. On je dugogodišnji zagovornik usvajanja bitkoina u svetu u razvoju, kao i kritičar CFA franka – ali čak i on oseća da je CAR-ova šema bila „izuzetno neosmišljena“.

„Iako imam mnogo simpatije prema ranjivoj i siromašnoj naciji koja usvaja bitkoin kao drugu valutu – posebno naciji koja je decenijama i decenijama finansijski kontrolisana od strane svoje bivše kolonijalne sile, nisam baš optimističan u pogledu toga kako je to izvedeno“, rekao je za VICE.

Dodao je: „Zaista se čini da je cela ova stvar bila kao prevara da se Sangocoin promoviše. Ne mislim da je cilj bio da se bitkoin integriše na smislen način u ekonomiju zemlje. Čini se da je predsednik zainteresovan za bitkoin i da postoji mala grupa ljudi oko njega koja je iskoristila taj interes da bi mogla da donese ove zakone kako bi pokušala da pokrene Sangocoin, od kojeg su imali viziju da zarade gomilu novca. Ali izgleda da je na kraju uspela da prikupi samo malo novca.”

Gladstein kaže da bi Bitcoin mogao biti „veoma važna finansijska tehnologija za ljude Centralnoafričke Republike tokom vremena, i pametno je da vlada istraži kako to može pomoći ljudima“, ali je potrebno mnogo posla da se to postigne.

Vlada Centralnoafričke Republike i opoziciona vlada nisu odgovorile na nekoliko zahteva za intervju.

Safe Bits & Self Custody Tips

The journey of onboarding a user and create a bitcoin multiSig setup begins far before opening a desktop like Bitcoin Safe (BS) or any other similar application. Bitcoin Safe seems designed for families and people that want to start exploring and learning about multiSig setup. The need for such application and use of it could go much further, defining best practices for private organizations that aim to custody bitcoin in a private and anonymous way, following and enjoy the values and standards bitcoin has been built for.

Intro

Organizations and small private groups like families, family offices and solopreneurs operating on a bitcoin standard will have the need to keep track of transactions and categorize them to keep the books in order. A part of our efforts will be spent ensuring accessibility standards are in place for everyone to use Bitcoin Safe with comfort and safety.

We aim with this project to bring together the three Designathon ideas below: - Bitcoin Safe: improve its overall design and usability. - No User Left Behind: improve Bitcoin Safe accessibility. - Self-custody guidelines for organizations: How Bitcoin Safe can be used by private organization following best self-custody practices.

We are already halfway of the first week, and here below the progress made so far.

Designing an icon Set for Bitcoin Safe

One of the noticeable things when using BS is the inconsistency of the icons, not just in colors and shapes, but also the way are used. The desktop app try to have a clean design that incorporate with all OS (Win, macOS, Linux) and for this reason it's hard to define when a system default icon need to be used or if a custom one can be applied instead. The use of QT Ui framework for python apps help to respond to these questions. It also incorporates and brig up dome default settings that aren't easily overwritten.

Here below you can see the current version of BS:

Defining a more strict color palette for Bitcoin Safe was the first thing!

How much the icons affect accessibility? How they can help users to reach the right functionality? I took the challenge and, with PenPot.app, redesigned the icons based on the grid defined in the https://bitcoinicons.com/ and proposing the implementation of it to have a cleaner and more consistent look'n feel, at least for the icons now.

What's next

I personally look forward to seeing these icons implemented soon in Bitcoin Safe interface. In the meantime, we'll focus on delivering an accessibility audit and evaluate options to see how BS could be used by private organizations aiming to become financially sovereign with self-custody or more complex bitcoin multiSig setups.

One of the greatest innovations BS is bringing to us is the ability to sync the multiSig wallets, including PBST, Categories and labels, through the nostr decentralized protocol, making current key custodial services somehow obsolete. Second-coolest feature that this nostr implementation brings is the ability to have a build-in private chat that connect and enable the various signers of a multiSig to communicate and sign transactions remotely. Where have you seen something like this before?

Categories UX and redesign is also considered in this project. We'll try to understand how to better serve this functionality to you, the user, really soon.

Stay tuned!

Wir sprechen kein Wort mehr miteinander, weil es weh tut

Viele Menschen haben in den letzten Jahren den Kontakt zu wichtigen Bezugspersonen verloren. Viele Menschen haben auch neue Leute auf der Straße oder durch Netzwerke kennen gelernt. Und manche Menschen hatten das Glück, schon vor der inszenierten Krise einen unterstützenden und stabilen Freundeskreis zu haben und haben diesen immer noch. Manchmal kommen alte Leute wieder zurück ins Leben, weil sie merken, dass man es gut mit ihnen meinte, als man vor den unglaublichen Lügen der Amtsträger warnte. Manchmal kommen alte Leute auch nicht mehr zurück, weil die Scham, auf falsche Versprechen herein gefallen zu sein, zu groß ist. Man gibt sich dann nach außen unverändert souverän und zieht es vor, still und heimlich zu leiden. Die neuen Kontakte bestehen manchmal leider auch nur temporär, sind zweckgebunden. Kaum ist die gemeinsame Aufgabe vollbracht, trennen sich die Wege wieder.

All das muss man in diesen Tagen  gehäuft aushalten. Alles verändert sich in stärkerem Maße als sonst. Viele dieser Veränderungen tun weh. Man kann sich auf Trauma nicht vorbereiten. Nie.

Ich möchte jetzt keine schlichten Alltagsbeobachtungen darüber widergeben, wie ich selbst oder Menschen in meinem Umfeld in den letzten Jahren ihre Beziehungen erlebt haben. Vielmehr geht es mir auch in diesem Artikel wieder um das Thema Trauma und um die Folgen, die jedes einzelne Trauma auch gesamtgesellschaftlich betrachtet hat. Was passiert, wenn man eine bereits durch Kriege traumatisierte Gesellschaft noch zusätzlich jahrelang unter Druck setzt, so wie dies in den letzten fünf Jahren geschehen ist? Wieviel Trauma verträgt eine Gesellschaft? Wie verändern sich Beziehungen in einer Gesellschaft, die immer wieder erneut traumatisiert wird? Ist irgendwann das Maß des Erträglichen voll? Und wenn ja, wie äußert sich solch eine Kumulation von Traumafolgen?

Meines Erachtens sehen wir gerade genau die Ergebnisse solch einer Kumulation von Traumafolgen in unserer deutschen Gesellschaft, vielleicht sogar global: Menschen reden nicht mehr (vertieft) miteinander. Und dies ist nur eine von vielen Traumafolgen.

Ich freue mich über jeden Leser, der jetzt noch weiterliest.

Durch genügend Traumatisierung kann man Menschen offensichtlich zeitweise dazu bringen, dass sie nicht mehr (vertieft) miteinander reden, weil das Reden weh tut.

Traumatisierung ist daher eine effektive Strategie der vermeintlich Herrschenden, Menschen zu separieren.

Traumatisierung setzt tiefe Verletzungen und macht Menschen vorübergehend sprachlos. Es fehlen einem die Worte. Man möchte dann nicht reden. Aber man verschließt sich auch vor den Worten anderer, weil man keine weitere Verletzung mehr erträgt.

Menschen im Alltag erachten es vielleicht mittlerweile schon als normal, wenn Beziehungen nicht gut laufen, egal, um welche Art von Beziehung es sich handelt. Sobald Probleme auftauchen, wird erst kurz gestritten, dann geschwiegen und wenn man das Schweigen nicht mehr aushält, dann gibt es entweder noch einen Versuch oder man geht gleich auf Distanz und bricht den Kontakt ganz ab. Auch meine Zündschnur ist manchmal immer noch gefühlt zu kurz. Wenn man sich Distanz nicht erlauben kann, dann frisst man das Problem in sich hinein, spült es runter, kompensiert irgendwie, wartet darauf, dass sich von allein etwas ändert oder dass sich eine bessere Gelegenheit bietet, bei der man dann die Biege machen kann. Mehrere Eisen im Feuer zu haben, beruflich wie privat, gilt als clever. Probleme nicht anzusprechen, gilt als kompetent. Das Wort Teamfähigkeit ist im Berufsleben zu einem Kampfbegriff geworden. Wer im Arbeitskontext Probleme anspricht, ist offensichtlich nicht teamfähig. Die Frage „Sind Sie teamfähig?“, erzählt meines Erachtens mehr über den Chef als über den Mitarbeiter. Die passendere Frage wäre wohl „Können Sie sich wortlos an schlechte Zustände dauerhaft adaptieren?“ In privaten Beziehungen braucht man, wenn es nicht so gut läuft, einen stilvollen Urlaub oder eine neue Wohnzimmereinrichtung, um endlich mal wieder schöne Gefühle erleben zu können. Negative Gefühle sind scheinbar das Kind, das keiner haben wollte, weshalb es die schönsten Kleider bekommt. Auch ich kenne Ablenkung von negativen Gefühlen durch Konsum und Essen. Es lohnt sich, mal den Werbeslogans von Möbelhäusern, Ferienanbietern oder Lebensmittelhändlern bewusst zuzuhören. Die Werbung kennt unsere Sehnsüchte und damit auch unsere negativen Gefühle besser als wir selbst. Und für alle, die nicht konsumieren wollen, die nicht locker lassen und steif darauf beharren, dass es aber ein Problem in der Beziehung oder am Arbeitsplatz oder zumindest eine gewisse Unzufriedenheit gäbe, für diese Menschen gibt es garantiert ein passendes Coaching- oder Weiterbildungsprogramm mit Namen wie „In 12 Modulen zur Selbstentfaltung“, welches nur deshalb meist nicht funktioniert, weil man es angeblich nicht richtig durchgeführt hat oder vorab noch das Basismodul absolvieren muss. Bildung ist mittlerweile auch ein Markt, der  Konsumgüter in Form von Coachings und Seminaren anbietet.

Auch ich bin übrigens lange zusammen gezuckt bei der Frage „Sind sie teamfähig?“ oder der Feststellung „Du bist das Problem, weil Du immer alles so genau nimmst, nicht die Fünf gerade sein lassen kannst.“ Am Ende ist man immer der Dumme, wenn man ein negatives Gefühl hat und darüber sprechen möchte. Trauma löst Scham UND Wut in einer Person aus. Scham zieht Abwertung an wie Licht die Motten anzieht. Und irgendwann platzt einem der Kragen. Man teilt selber aus. Und dann schämt man sich erneut, nicht nur für das früher oder später erlittene Trauma im Leben, sofern einem das bewusst ist, sondern auch für die unbeherrschte Reaktion, die man oft selbst nicht richtig versteht. Nicht bearbeitetes Trauma arbeitet unbewusst in uns.

Eine traumatisierte Gesellschaft wertet sich ständig gegenseitig ab und hält genau damit die Wunden offen.

Dann ist es vielleicht doch besser, das Problem in der Beziehung oder am Arbeitsplatz runter zu schlucken, auf Distanz zum anderen zu gehen, sich schon mal nach einer neuen Wohnzimmereinrichtung, einem neuen Partner oder einem neuen Job umzuschauen? Ich denke nicht, dass das eine Lösung ist.

Hinschauen und Gefühle bei sich und anderen zulassen, ist ein guter Anfang.

Wir gehen oft Beziehungen ein, gehen aber   gleichzeitig   einer echten tiefen und anhaltenden Verbindungen privat wie beruflich instinktiv aus dem Weg, weil echte tiefe Gespräche, zu denen es in solchen Verbindungen kommen kann, weh tun können, insbesondere wenn man noch unverarbeitetes Trauma mit sich herum schleppt. Und in einer traumatisierten Gesellschaft, tragen halt viele Menschen solche traumatisierten und nicht bearbeiteten Anteile mit sich herum.

Wir sind die Kinder und Kindeskinder der Menschen, die den zweiten Weltkrieg hautnah miterlebt haben. Alles, was die Eltern und Großeltern nicht besprochen, nicht verarbeitet haben, tragen wir weiter mit uns herum. Das ist den meisten Menschen, meines Erachtens, nicht bewusst. Mag sein, dass an dieser Stelle der eine oder andere widerspricht. Widersprechen Sie mir gerne. Meine Alltagserfahrung ist eine andere. Die Art, wie wir Beziehungen gestalten, spricht Bände. Aber, wenn man es nicht anders kennt und keine Kontrollgruppe hat, sagt man sich halt: „So isses. Und so isses normal. Ich kenne es nicht anders. Das machen doch alle so.“

Es ist so normal, in unserer Gesellschaft, nicht vertieft über negative (und auch positive) Gefühle zu reden. Alleine die Bezeichnung „negative Gefühle“ klingt schon wenig einladend. Und es ist auch so normal, Menschen in dem Moment, wo sie gegen jede Empfehlung nicht nur über negative Gefühle reden wollen, sondern diese sogar live und in Farbe zeigen, abzuwerten, oder noch schlimmer, zu ignorieren, weil man sich verunsichert fühlt, nicht weiß, wie man damit umgehen soll. Gefühle scheinen ansteckend zu sein. Da ist Vorsicht geboten. Ich persönlich kann mich an viele solcher Momente erinnern, wo Menschen nicht gern hören wollten, wovor ich Angst hatte, was und wer mich verletzt und wütend gemacht hatte, beruflich wie privat. Mit geäußerter Angst und Trauer macht man(n) sich ganz schnell lächerlich. Mit Wut hingegen wird ein Mann von anderen als stark bis beängstigend wahrgenommen. Ein Mann, der wütend agiert, wird eher als kraftvoll und temperamentvoll eingeschätzt. Eine Frau wird mit Wut dann akzeptiert, wenn sie bereits in einer (männlichen) Führungsrolle ist. „Sie“ muss schließlich ihren „Mann“ stehen. Hat sie keine Führungsrolle, wird sie abgewertet oder befördert. Dem wütenden Mann wird eher unterstellt, er habe schließlich einen wichtigen Auftrag zu erfüllen. Der Frau wird eher ein Mangel unterstellt, den ich hier nicht näher bezeichnen möchte. Darin spiegeln sich sehr starre Rollenvorstellungen von Mann und Frau in unserer Gesellschaft wider. Ängstliche Frauen, die bei einer Autopanne bezaubernd aussehen, erfüllen ein bestimmtes Klischee. Impulsive Männer mit Holzfällerhemd erfüllen zumindest auf einer Baustelle ein anderes Klischee. Menschen mit ausgeprägten negativen Gefühlen werden unter bestimmten Umständen glorifiziert. Der bezaubernd aussehenden Frau mit Autopanne wird schnell und gerne geholfen. Aber wenn die ängstliche Frau eine Vorgesetzte ist und der impulsive Mann mit Holzfällerhemd ein Kunde in einem Beratungsbüro ist, dann kann die Bewertung ganz anders ausfallen. Dann sind diese Gefühle vermeintlich fehlplatziert. Gefühle scheinen einen Platz zu haben. Die ängstliche Vorgesetzte hat eine Führungsschwäche und der impulsive Kunde im Beratungsbüro wird vom Sicherheitsdienst „entfernt“. Der Wunsch, über die gezeigten negativen Gefühle zu reden, wird einem mit Nachdruck verwehrt. Durch diesen vermeidenden Umgang mit negativen Gefühlen oder die Fehlinterpretation dieser Gefühle kommt es meines Erachtens oft zu bestimmten Rollenbesetzungen im Berufsleben. Eine positive Selektion von Mitarbeitern mit sehr rücksichtslosem oder überangepasstem Verhalten findet statt. In privaten Beziehungen werden negative Gefühle durch Ablenkung und Konsum vermieden. Es werden zu viele oder zu wenige Kontakte gepflegt. Beziehungen werden gar nicht mehr für die Ewigkeit antizipiert. Man hält sich alle Wege offen und lernt ständig neue Leute kennen. Oder man lebt Beziehung in sehr starren Strukturen, wo neue Informationen kaum Eingang finden, damit man sich nicht hinterfragen und mit anderen vergleichen muss. Lebensphasen mit dem weit geöffneten oder dem eher geschlossenen Muster wechseln sich auch manchmal ab. Individuelle Entwicklungen des einen oder anderen Musters in Lebensverläufen, zeichnen sich irgendwann als gesellschaftliche Strömung ab, wenn sie bei vielen Menschen gleichzeitig geschehen. Menschen wollen alles ausprobiert haben, bevor sie sich das Reihenhaus kaufen. Andere verkaufen ihr Reihenhaus nach der Scheidung, um im Wohnmobil durch die Welt zu tingeln. Man könnte denken, dass dies einfach individuelle Lebensverläufe sind, die sich zufällig so ergeben haben. Es gab Zeiten, wo Menschen zufällig viel Halt in starren Beziehungs- und Lebensstrukturen fanden. Gegenbewegungen brachen diese starren Strukturen nicht wirklich auf, weil sie Feuer mit Feuer bekämpften. Grundsätzlich gegen alles zu sein, was die Eltern vorgelebt haben, ist ja auch irgendwie rigide. Der Apfel fällt nicht zufällig neben den Stamm. Heute 80 Jahre nach Kriegsende können Menschen mit Begriffen wie Achtsamkeit und bewusster Kommunikation immer mehr anfangen, jedoch geht die weit verbreitete Bewusstheit und Selbstreflektiertheit oft zu Lasten einer wünschenswerten Verarbeitungstiefe. Zu oft  werden  wir gedacht, gefühlt und gelenkt. Um dies mit uns machen zu können, werden von vermeintlich Herrschenden wichtige Orientierungspunkte wie die eigene Geschichte, Kultur und Sprache falsch erzählt oder bis zur Unkenntlichkeit verändert. Und eigene Gefühle, die einem noch letzten Halt und Orientierung in diesem Dschungel bieten könnten, werden vom Kapitalismus ausdauernd gejagt wie ein seltenes Tier. Separierung und Orientierungslosigkeit ist gewollt.

Alles dreht sich um unsere tiefen Gefühle, insbesondere diese negativen Gefühle, die aus Trauma entstehen. Diese Gefühle wollen gesehen, gehört und bearbeitet werden. Sie machen zum Glück, solange es die Menschheit gibt, zuverlässig auf sich selbst aufmerksam. Sie sind in Wahrheit unsere Lebensversicherung. Die Zeit heilt gar nichts. Und hierfür braucht es wieder ein Bewusstsein, dass Gefühle wertvoll sind, auch solche, die aus Trauma entstehen. Ich persönlich habe dafür mehr als ein halbes Leben gebraucht, um dies zu verstehen. Als junge Frau habe ich nicht gewusst, dass viele meiner Gefühle, negativ wie positiv, Ausdruck meines Traumas waren. Heute weiß ich, dass ich mit dieser Einschätzung, die ich damals hatte, in „guter Gesellschaft“ war. Den meisten Menschen geht das so, bis sie irgendwann ihr eigenes Trauma erkennen.

Wir sind eine traumatisierte Gesellschaft, und die Arten und Ausprägungen von Trauma sind so vielfältig und den meisten Menschen unbekannt wie die Namen der Blumen auf einer Sommerwiese.

Wenn man diesen Satz wirken lässt, dann stellt sich doch die Frage:

Wie sieht denn ein gesunder Umgang mit negativen (und positiven) Gefühlen aus?

Reicht es aus, wenn man die Namen aller Wiesenblumen auswendig lernt, damit man jedes Trauma genau bestimmen kann? Oder geht es mehr um das Fühlen und weniger um das Wissen?

Den gesunden Umgang mit meinen Gefühlen habe ich nicht durch Theorie und Bücher erlernt, sondern durch den Alltag, durch die (emotionalen) Reaktionen meiner Mitmenschen und durch das bewusste Spüren und Zulassen meiner eigenen Gefühle. In Stufen lernte ich meine Gefühle immer besser kennen und mit ihnen umzugehen. Je besser ich sie kannte, umso lieber waren sie mir. Und ich lerne sie immer noch weiter und besser kennen. Das ist ein Prozess.

Traumabearbeitung ist anfangs ein anstrengender Prozess. Man sollte das langsam angehen. Aber diese Arbeit ist sehr lohnenswert, weil sie einem viele glückliche Momente, Kraft und Lebensfreude schenkt. Reden wird dadurch leichter und bringt in allen Lebensbereichen Fortschritte. Manchmal tut Reden auch weh (siehe Titel), aber zeitgleich, und auch langfristig gesehen, wird das Leben schöner durch Traumabearbeitung. Es geht nicht um Schmerzvermeidung, sondern darum, mit dem Schmerz gut umgehen zu können. Denn dadurch wird er letztlich kleiner und verwandelt sich zur Wiesenblume. Es geht um Verwandlung durch Fühlen. Die Erfahrung, dass man Trauma bearbeiten kann, erzählt mir so viel über dieses Leben, wie stark es ist, wie sehr es uns liebt und welche Blüten daraus wachsen können. Viele schöne Dinge, die wir täglich sehen, sind aus bewältigtem Trauma oder dem Wunsch, Trauma zu bewältigen, entstanden.

Der Schmerz lehrt uns Demut vor dem Leben und kreiert nebenbei die schönsten Lieder und Kunstwerke. Trauer und Verlust betonen den Wert der Dinge. Ärger und Wut bringen uns in Wallungen und stellen die Energie bereit, die man manchmal braucht, um Berge zu versetzen. Ängste sind das Tor zum Glück. Schuld und Scham lehren uns Vergebung. Neid und Eifersucht lassen unseren Selbstwert wachsen, wenn wir uns ihnen stellen. Und Freude, Glück und Ekstase machen uns dankbar, großzügig und optimistisch.

Wenn wir diese Gefühle wieder zulassen, dann können wir gar nicht anders als reden. Wir reden dann wieder vertieft miteinander, weil es gut tut, weil es entlastet, weil es Nähe zu anderen vielleicht erstmalig aufbaut und dann zu einem dicken Band verstärkt bis ein großes stabiles Netz daraus entsteht, welches Menschen, die gerade Halt benötigen, diesen bieten kann.

Wir reden dann wieder miteinander, weil es gut tut.

I remember the first gathering of Nostr devs two years ago in Costa Rica. We were all psyched because Nostr appeared to solve the problem of self-sovereign online identity and decentralized publishing. The protocol seemed well-suited for textual content, but it wasn't really designed to handle binary files, like images or video.

The Problem

When I publish a note that contains an image link, the note itself is resilient thanks to Nostr, but if the hosting service disappears or takes my image down, my note will be broken forever. We need a way to publish binary data without relying on a single hosting provider.

We were discussing how there really was no reliable solution to this problem even outside of Nostr. Peer-to-peer attempts like IPFS simply didn't work; they were hopelessly slow and unreliable in practice. Torrents worked for popular files like movies, but couldn't be relied on for general file hosting.

Awesome Blossom

A year later, I attended the Sovereign Engineering demo day in Madeira, organized by Pablo and Gigi. Many projects were presented over a three hour demo session that day, but one really stood out for me.

Introduced by hzrd149 and Stu Bowman, Blossom blew my mind because it showed how we can solve complex problems easily by simply relying on the fact that Nostr exists. Having an open user directory, with the corresponding social graph and web of trust is an incredible building block.

Since we can easily look up any user on Nostr and read their profile metadata, we can just get them to simply tell us where their files are stored. This, combined with hash-based addressing (borrowed from IPFS), is all we need to solve our problem.

How Blossom Works

The Blossom protocol (Blobs Stored Simply on Mediaservers) is formally defined in a series of BUDs (Blossom Upgrade Documents). Yes, Blossom is the most well-branded protocol in the history of protocols. Feel free to refer to the spec for details, but I will provide a high level explanation here.

The main idea behind Blossom can be summarized in three points:

1. Users specify which media server(s) they use via their public Blossom settings published on Nostr;
2. All files are uniquely addressable via hashes;
3. If an app fails to load a file from the original URL, it simply goes to get it from the server(s) specified in the user's Blossom settings.

Just like Nostr itself, the Blossom protocol is dead-simple and it works!

Let's use this image as an example:

If you look at the URL for this image, you will notice that it looks like this:

blossom.primal.net/c1aa63f983a44185d039092912bfb7f33adcf63ed3cae371ebe6905da5f688d0.jpg

All Blossom URLs follow this format:

[server]/[file-hash].[extension]

The file hash is important because it uniquely identifies the file in question. Apps can use it to verify that the file they received is exactly the file they requested. It also gives us the ability to reliably get the same file from a different server.

Nostr users declare which media server(s) they use by publishing their Blossom settings. If I store my files on Server A, and they get removed, I can simply upload them to Server B, update my public Blossom settings, and all Blossom-capable apps will be able to find them at the new location. All my existing notes will continue to display media content without any issues.

Blossom Mirroring

Let's face it, re-uploading files to another server after they got removed from the original server is not the best user experience. Most people wouldn't have the backups of all the files, and/or the desire to do this work.

This is where Blossom's mirroring feature comes handy. In addition to the primary media server, a Blossom user can set one one or more mirror servers. Under this setup, every time a file is uploaded to the primary server the Nostr app issues a mirror request to the primary server, directing it to copy the file to all the specified mirrors. This way there is always a copy of all content on multiple servers and in case the primary becomes unavailable, Blossom-capable apps will automatically start loading from the mirror.

Mirrors are really easy to setup (you can do it in two clicks in Primal) and this arrangement ensures robust media handling without any central points of failure. Note that you can use professional media hosting services side by side with self-hosted backup servers that anyone can run at home.

Using Blossom Within Primal

Blossom is natively integrated into the entire Primal stack and enabled by default. If you are using Primal 2.2 or later, you don't need to do anything to enable Blossom, all your media uploads are blossoming already.

To enhance user privacy, all Primal apps use the "/media" endpoint per BUD-05, which strips all metadata from uploaded files before they are saved and optionally mirrored to other Blossom servers, per user settings. You can use any Blossom server as your primary media server in Primal, as well as setup any number of mirrors:

## Conclusion

For such a simple protocol, Blossom gives us three major benefits:

1. Verifiable authenticity. All Nostr notes are always signed by the note author. With Blossom, the signed note includes a unique hash for each referenced media file, making it impossible to falsify.
2. File hosting redundancy. Having multiple live copies of referenced media files (via Blossom mirroring) greatly increases the resiliency of media content published on Nostr.
3. Censorship resistance. Blossom enables us to seamlessly switch media hosting providers in case of censorship.

Thanks for reading; and enjoy! 🌸

Ako ste makar djelić vremena proveli u svijetu digitalnog novca, vjerovatno ste naišli na termin HODL – uvijek napisan velikim slovima tako da na prvi pogled djeluje kao riječ sa slovnom greškom. Zapravo i jeste riječ o slovnoj grešci i to onoj koja je nastala na današnji dan prije 11 godina, a koja je uspjela ne samo da obezbijedi mjesto u istoriji svijeta novca, već i da postane naziv za jedan potpuno drugačiji pristup sredstvima koja posjedujemo.

Nespretno napisana riječ „hold“ (eng. držati, zadržati) u poruci na jednom forumu evoluirala je u akronim HODL – akronim za Hold On for Dear Life (doslovno – drži se za život, tj. drži se kao da ti život zavisi od toga), predstavlja poziv na akciju – ili, tačnije, „neakciju“ za vlasnike kriptovaluta da odole iskušenju prodaje tokom tržišnih padova. Riječ je o shvatanju da je ovaj oblik digitalne imovine bolje vremenski što duže imati u vlasništvu, kako bi se sačekao mnogo povoljniji trenutak za prodaju nego prodati ih u vremenu kada je situacija na tržištu loša.

Greška koja je postala pokret

Priča počinje 18. decembra 2013. godine, kada je cijena bitcoina tada počela da pada, a samo tokom toga dana se sa 682 na 522 dolara. Korisnik foruma pod imenom GameKyuubi objavio je sada već legendarni post pod naslovom „I AM HODLING“. Bila je to greška u kucanju, jer se na osnovu sadržaja poruke vidi da je krenuo da napiše „holding“ (držim), ali umjesto da se ispravi sebe, prigrlio je grešku, šaljivo govoreći o svom nedostatku vještina za trgovanje i zašto „bez obzira na sve“.

Bitcoin zajednica brzo je prihvatila ovaj izraz kao dio slenga. Pogrešno napisana riječ odjeknula je internet prostranstvima, a vremenom je prerasla u simbol šire filozofije – ne paniči, ne prodaj i ne dozvoli da kratkoročna nestabilnost poljulja tvoje uvjerenje. Od kasnonoćnog posta na forumu, HODL je postao poklič za vlasnike bitcoina (i drugih, u to vrijeme malobrojnih digitalnih valuta zanemarive vrijednosti) širom svijeta.

HODL-ovanje i HODL-eri

U suštini, HODL-ovanje je strategija zadržavanja kriptovaluta tokom tržišnih uspona i padova, zasnovana na uvjerenju da će cijene vremenom rasti. Umjesto impulsivnog reagovanja na tržišne fluktuacije, HODL-eri se posvećuju svojim investicijama na duže staze.

Ovaj pristup posebno je koristan za početnike, koji možda nemaju dovoljno stručnosti ili hrabrosti da se nose sa svakodnevnim trgovanjem (u čemu su često neuspješni i dugogodišnji vlasnici digitalnih novčića). Sam GameKyuubi u svom originalnom postu priznao je da samo najvještiji trgovci treba da pokušaju da „igraju igru“ tokom tržišnih padova. Za ostale, HODL-ovanje nije samo sigurnije, već je često i pametnije.

Filozofija HODL-ovanja zasnovana je na povjerenju – u budućnost kriptovaluta, u eventualni oporavak tržišta i u korist koju donosi strpljenje. To je odbijanje da se prodaje kada cijene naglo padnu – nepokolebljivo uvjerenje da su padovi privremeni i da nakon njih slijedi rast.

Zakon tržišta pokazuje da što drže HODL-ujete to se ova strategija više isplati, a cijena bitcoina u njegovoj šesnaestogodišnjoj istoriji je nesumnjivo najbolji dokaz za to. Trgovanje zahtijeva mnogo učenja, truda, vremena provedenog u praćenju svakog mogućeg signala, dok je kod HODL-ovanja važno samo da se „ne predate“.

Ako ste prethodnih godina nešto platili bitcoinom (a trgovci širom svijeta su to omogućili upravo da bi vas naveli da ih umjerite ka njima) vjerovatno ste zažalili, jer danas dok je njegova vrijednost i u dolarima i u eurima šestocifrena, ono na što ste ih potrošili ipak izgleda kao nešto što je trebalo platiti fizičkim novcem (kojeg je svakako „pojela inflacija“).

Pouzdane kriptovalute, a tu se prije svega misli na bitcoin, iako veoma volatilne bilježe trend rasta na duge staze, pa HODL-ovanje znači strpljenje u vremenu neizvjesnosti s idejom o koristi na duži rok, čak i kada su godine loše, kao što su bile 2014, 2017. i 2022. Na primjer, u periodu od 20. maja do 20. juna cijena bitcoina kliznula je sa 29.000 na 18.000 dolara, a upravo u tom trenutku mnogi su odlučili da količinu koju posjeduju prodaju ili je potroše plaćajući ovom digitalnom valutom (i pokajali se zbog toga).

HODL naspram drugih strategija

HODL-ovanje se razlikuje od aktivnijih strategija, poput kupovine po niskoj cijeni i prodaje po visokoj, jer dok trgovci pokušavaju da tempiraju tržište radi brze zarade, HODL-eri ostaju dosljedni svojoj odluci da se ne oslobađaju svoje imovine ni u najnoepovoljnijim trenucima. HODL-eri ne pokušavaju da predvide kretanje cijena – jednostavno čuvaju svoja sredstva, svjesni toga da će strpljenje na kraju donijeti rezultat.

Naravno, HODL-ovanje ima i svoje nedostatke. Za razliku od trgovaca koji mogu da povećaju svoj kapital kroz stratešku kupovinu i prodaju, HODL-eri zavise od vremena provedenog u čekanju na dugoročne rezultate. Pored toga, masovno HODL-ovanje može usporiti cirkulaciju kriptovaluta na tržištu, smanjujući ukupnu ekonomsku aktivnost – drugim riječima, kada bismo svi bili HODL-eri odnos ponude i tražnje bi bio veoma destimulišući i to bi oborilo cijenu.

Na sreću, trgovaca ima mnogo – dovoljno da tržište stalno bude aktivno i dinamično, no za one koji nemaju vremena, vještine ili sklonost ka riziku koji nosi trgovanje, HODL-ovanje ostaje jednostavan, ali veoma efikasan pristup.

Filozofija HODL-ovanja

HODL-ovanje je više od investicione strategije – to je način razmišljanja koji obuhvata otpornost, strpljenje i vjerovanje da su kratkotrajno suzdržavanje i nepokolebljivost u odluci da se sredstva sačuvaju vrijedna dugoročnog dobitka. Bilo da cijena bitcoina raste ili pada je, filozofija HODL-ovanja ostaje ista – ostanimo dosljedni, vjerujmo procesu i gledajmo u budućnost.

Jedan od ključnih razloga zašto većini ljudi ovakav pristup dugo nije bio razumljiv je zbog toga što su čitav sistem novca prihvatili u uvjerenju da on vremenom devalvira. Vjerovatno ste makar jednom razmatrali ponudu oročene štednje i procijenili da vam količina novca koju želite da položite neće donijeti onaj prinos koji će očuvati njegovu kupovnu moć nakon određenog broja godina, jer je kontinuirano doštampavanje novca podupiralo tu tvrdnju.

Dakle, ne treba da vas zavara sve ono što znate o novcu kao takvom, budući da bitcoin (na kojem je u ovom serijalu poseban fokus, jer mnoge druge kriptovalute ipak češće razočaraju nego što oduševe) nije novac, već samo ima neka svojstva novca. Posmatrajte ga radije kao imovinu – npr. kao nekretninu za koju sigurno želite da prodate onda kada je situacija stabilnija i kada su mnogo veće šanse da pronađete kupca kojem ćete je prodati po višoj cijeni.

U svakom slučaju, ako se u vašem digitalnom novčaniku već nalazi poneki satoshi (stomilioniti djelić bitcoina), kada tržište ponovo uđe u nepovoljnu fazu i zavlada prolazna panika, sjetite se onoga što je napisao GameKyuubi. HODL nije samo izraz – to je način da se prebrode oluje i izazovi koje nestabilno tržište nosi.

Originalni rad

Apstrakt

Kriptovalute (engl. "cryptocurrency") su digitalne (virtualne) valute, koje iako su sredstvo razmene, još uvek nisu strogo regulisane zakonom u većini država, a u pojedinim su čak i zabranjene. Veliki broj ljudi, uključujući i IT stručnjake i programere ne znaju mnogo o ovoj temi, a šira javnost izjednačava pojmove blokčejna i bitkoina. Tržište kriptovaluta danas iznosi gotovo 770 milijardi dolara. Od pojave prvih digitalnih valuta do danas, nastalo je preko 1.300 aktivnih kriptovaluta koje se razlikuju prema svojim svojstvima i upotrebi. Pre bitkoina bilo je mnoštvo neuspelih pokušaja stvaranja digitalnih valuta (digikeš, heškeš, Fejsbuk kredit i dr.). Utopistička ideja da matematika i fizika mogu rešiti društvene probleme započela je svoj život kroz pojavu bitkoina. Genijalna ideja po kojoj funkcioniše bitkoin zasnovana je na tehnologiji blokčejna, čiji kapacitet doseže daleko iznad kripto valuta. Iako se još uvek vode polemike ko stoji iza pseudonima Satoši Nakamoto, njegova zaostavština ima potencijal da promeni svet. Uspeh bitkoina leži u prednostima koje ima u odnosu na druge slične valute, ali njegov značaj prevazilazi i pogodnosti koje je doneo. Banke nisu potrebne za čuvanje podataka o novcu, evidenciju o imovini i svakoj transakciji bitkoina čuvaju računari svih korisnika mreže u zajedničkoj bazi podataka blokčejnu. Sve transakcije su mnogo brže od bankarskih, bez taksi, uz drastično lakše plaćanje preko državnih granica. Bitkoin svojim korisnicima pruža bezbednosti bez identifikacije, iako blokčejn beleži transakciju, ne beleži ko stoji iza nje. U radu su predstavljeni osnovni principi na kojima su zasnovani bitkoin i druge kriptovalute, pojašnjen odnos između blokčejna i bitkoina.

1 UVOD

Ideal o novcu koji se ne oslanja na centralne institucije (koje mogu propasti, ali i koje vrše nadzor nad korisnicima), postojao je decenijama. U digitalnom svetu prvi ga je uobličio pisac naučne fantastike Nil Stivenson 1999. godine u svojoj noveli Kriptonomikon. On je opisao podzemni svet koji funkcioniše zahvaljujući digitalnom zlatu zasnovanom na kriptografiji, pri čijoj upotrebi korisnici ne moraju odavati ko su i šta su (Popper, 2016).

Kriptovalute (engl. cryptocurrency) su digitalne (virtualne) valute, koje iako su sredstvo razmene, još uvek nisu strogo regulisane zakonom u većini država, a u pojedinim su čak i zabranjene (Jovanović, 2014).

Da bi se razumeo nastanak i funkcionisanje kriptovaluta, neophodno je sagledati ih iz različitih uglova na kojima su one bazirane: matematici, sociologiji, ekonomiji, pravu i politici. To je verovatno i glavni razlog zbog koga veliki broj ljudi (uključujući i IT stručnjake i programere) ne znaju mnogo o ovoj temi. Takođe, šira javnost izjednačava pojmove blokčejna i bitkoina.

Sve kriptovalute su bazirane na jedinstvenom nizu brojeva za svaku jedinicu valute, koje korisnici mogu jedni drugima slati preko mreže. U prošlosti su se ti nizovi mogli lako kopirati i trošiti više puta, zbog čega nisu imali vrednost. Kriptograf Dejvid Čaum je taj problem rešio stvaranjem jedinstvene centralizovane knjige, u kojoj su se čuvale beleške o transakcijama svakog korisnika, čime ni jedna jedinica valute više nije mogla da se nalazi na dva mesta istovremeno (Bertlet, 2016).

Kriptovalute svoj nastanak duguju težnjama levo orijentisanih utopističkih posvećenika IT tehnologija koji su sanjali o univerzalnom novcu koji bi svako mogao da poseduje i troši, čija je vrednost onolika koliko su korisnici voljni da plate (na principu ponude i potražnje), ali pre svega na liniji fronta za onlajn anonimnost i slobodu, bez cenzure i nadzora. Pojavi bitkoina prethodio je Sajberpankerski manifest Done Haravej (Haraway, 1985) koji počinje rečima: „U elektronsko doba, privatnost je neophodan uslov za postojanje otvorenog društva“.

Kriptovalute su univerzalni novac koji se može koristiiti bilo gde u svetu, one su lako prenosive i teško se krivotvore.

Neki podaci pokazuju da tržište kriptovaluta danas iznosi gotovo 770 milijardi dolara. Od pojave prvih digitalnih valuta do danas, nastalo je preko 1.300 aktivnih kriptovaluta koje se razlikuju prema svojim svojstvima i upotrebi.

Prema odredbama Zakona o Narodnoj banci Srbije celokupni unutrašnji promet u Republici Srbiji izražava se u dinarima, osim ako nekim zakonom nije drukčije određeno. „Zakonom o platnom prometu propisano je da se poslovi platnog prometa obavljaju u dinarima, a Zakonom o deviznom poslovanju da se plaćanje, naplaćivanje i prenos između rezidenata i između rezidenata i nerezidenata u Republici Srbiji vrši u dinarima, a izuzetno se može vršiti i u devizama u slučajevima koji su propisani ovim zakonom“ (NBS, 2014).

Tržište kriptovaluta u Srbiji postoji, sve je veći broj rudara. Iako trgovanje kriptovalutama nije nelegalno, Narodna Banka Srbije - NBS je u više saopštenja navela da one ne predstavljaju zakonsko sredstvo plaćanja u Republici Srbiji. Takođe, zbog toga što ih ne izdaje centralna banka, NBS za korišćenje virtuelnih valuta, ulaganje u njih, kao ni za njihovu vrednost. Narodna banka Srbije je više puta upozoravala javnost da virtuelne valute ne predstavljaju zakonsko sredstvo plaćanja u Republici Srbiji (NBS, Politika – u vezi s bitkoinom, 2017).

Ukoliko kriptovalute promatramo kao novac onda njihove tranksakcije mogu biti upitne shodno Zakonu o sprečavanju pranja novca i finansiranja terorizma, gde je propisana obaveza preduzimanja radnji i mera za sprečavanje pranja novca, kao što su identifikacija stranaka koje trguju preko tih platformi, uzimanjem kopije ličnog dokumenta. Kako poslovanje platformi na kojima se vrše transakcije kriptovalutama nije zakonom regulisano u Republici Srbiji, a uglavnom ni u uporednom pravu, a čl. 552. Zakona o obligacionim odnosima Republike Srbije ((„Sl. list SFRJ“, br. 29/78, 39/85, 45/89 - odluka USJ i 57/89, „Sl. list SRJ“, br. 31/93 i „Sl. list SCG“, br. 1/2003 - Ustavna povelja) predviđa razmenu robe kao jedan od načina trgovine, otvara se put ka legalnoj trgovini kriptovalutama (Bubanja, 2017).

Praksa je pokazala da su se korisnici kriptovaluta kada su imali problem sa njima, obraćali vlastima i njihovim regulatornim telima, zbog čijeg su zaobilaženja i smišljeni. Nažalost, korisnici ne uživaju pravnu zaštitu čak i kada je reč o trgovini putem registrovanih privrednih subjekta.

2 BITKOIN

Prva decentralizovana kriptovaluta koja se pojavila je bitkoin (eng. „Bitcoin“). Termin bitkoin označava istoimenu organizaciju, softver i protokol, kao i jedinicu mere ove kriptovalute (skraćeno BTC) (Bertlet, 2016). Koncept na kome se zasniva bitkoin prvi put je predstavljen 2008. godine u članku "Bitcoin: A Peerto-Peer Electronic Cash System", a u januaru 2009. godine bitkoin je pušten u promet. Njegov tvorac nije poznat do danas i krije se iza pseudonima Satoši Nakomato. Novu vrstu digitalne kriptovalute formirao je tako što je stvorio distribuirani sistem verifikacije. Bitkoin nastaje u procesu koji se naziva „rudarenje“ (engl. mining). Njegova jedinstvenost je u tome što je decentralizovana valuta, iza koje ne stoji nijedna država, niti banka. Bitkoin je digitalna valuta, koja nastaje i čuva se elektronski. Kriptovalute u cilju maksimizacije bezbednosti, upotrebljavaju metod - dokaz o radu (engl. proofof-work), metod baziran na informacijama koje je teško stvoriti, ali koje ostalim učesnicima u rudarenju obezbeđuju laku proveru i verifikaciju transakcija.

Kriptovalute se čuvaju na bitkoin adresama za koje ključ predstavlja jedinstven niz slova i brojeva. Svaka transkacija bitkoinom se beleži u blokovima koji se zovu blokčejn. Transakcije se hronološki ređaju u blokove, u svakom se nalazi digitalni potpis prethodnog bloka, time se uređuje redosled i garantuje da novi blok može da se pridruži lancu samo ako počne na mestu na mestu završetka prethodnog. Jedan od osnovnih činilaca bezbednosti bitkoina je da se kopija svake izvedene transakcije beleži na svakom nalogu na kome je instaliran bitkoin softver. Blokčejnove neprekidno verifikuju računari svih korisnika softvera, tako sistem zna u bilo kom trenutku, koliko bitkoina svaki korisnik u svom novčaniku poseduje. Novčanik je program koji služi za slanje, primanje i skladištenje kriptovaluta. Digitalni novčanik sadrži prikaz količine kriptovalute koju korisnik poseduje, zapise o svim njegovim transakcijama, korisnički tajni ključ i njegove adrese (Bertlet, 2016). Novčanik je moguće instalirati na računar, mobilni telefon i tablet.

Falsifikovanje bitkoina nije moguće, jer iako vlasništvo može da se menja ono se ne može nikada duplirati (Bertlet, 2016). On je pseudoanoniman, bitkoin mreža čuva sve podatke o svakoj transakciji koja se dogodila unutar mreže. Svako ko ima bitkoin softver i adresu na bitkoin mreži, može videti koliko novca ima na mreži, ali ne i kome oni pripadaju. Za razliku od otvaranja računa u bankama, otvaranje bitkoin računa (adrese) je brzo, bez troškova i „papirologije“. Jedna od glavnih prednosti bitkoin mreže je brzina transakcija.

Svako ko snagu svog računara posveti verifikaciji transakcija u blokčejnu može biti „rudar“. To je proces dodavanja transkacija u registar svih bitkoin transkacija. Rudarenje čini rešavanje matematičkog algoritma za čije se uspešno rešavanje dobija određena količina bitkoina.

Iako bitkoin ima reputaciju nestabilnosti, velikih fluktuacija i nezakonitog poslovanja, čemu mnogi pridodaju i urušavanje tradicionalnog koncepta nacionalnih država, ipak većina se slaže u tome da je njegova pojava najvažnija nova ideja od stvaranja Interneta (Vigna & Casey, 2016).

Razloga za uspeh bitkoina ima više. Finansijska kriza povoljno je uticala na njegov razvoj, poverenje u postojeći finansijski ali i politički sistem je bilo poljuljano i brojni korisnici su u njemu prepoznali drugačije rešenje.

Anonimnost koju pruža prilikom transakcija jedan je od ključnih razloga njegovog uspeha. Prilikom digitalnog plaćanja bitkoinom u većini slučajeva nije potrebno davanje ličnih podataka. Ovakva vrsta anonimnosti, nažalost pogodovala je i usponu tamne strane upotrebe i popularnosti bitkoina u kriminalnim krugovima.

Računi u bitkoinu nisu opterećeni visokim bankarskim dažbinama.

Takođe, nije beznačajan ni potencijal plaćanja izdataka koji su manji od trenutnih ograničenja u konvencijalnim transakcijama na internetu (npr. naplata čitanja jednog novinskog članka ili preskoči reklamu, koji koštaju manje od 20 ili 30 centi kolika je najmanja transakcija) (Popper, 2016).

Kao što su svi učesnici na internetu povezani protokolima (TCP/IP, FTP, SMTP, HTTP i dr.) zahvaljujući kojima mogu međusobno da komuniciraju, bitkoin je stvorio svoje softverske protokole koji uređuju funkcionalna pravila upravljanja sistemom.

Bitkoin je omogućio novi način stvaranja, čuvanja i transfera novca.

Od svog nastanka bitkoin se unapređivao, podržan od internet zajednice, posebno od posvećenika slobodi interneta i anonimosti, mnogi od problema koji su uočeni su rešavani zajedničkim naporom internet zajednice.

3 BLOKČEJN

Blokčejn (engl. blockchain) nije samo bitkoin, on je tehnologija za koju mnogi predviđaju da će promeni svet (OECD, 2018).

Ukoliko bismo pojednostavljeno opisivali blokčejn mogli bismo da kažemo da je to nova vrsta baze podataka, iako bi to bilo pojednostavljeno objašnjenje slično kao kada bi smo imejl (email) opisali kao novi način za slanje pisama.

Iako blokčejn jeste nova vrsta baze podatka, to ne objašnjava u dovoljnoj meri genijalnost načina na koji funkcioniše.

Kada bilo gde i bilo kada položimo novac, oslanjamo se na zapis u bazi podataka treće strane, banke, firme i sl. Poverenje u banke zasnovano je na zakonu koji reguliše rad banke, poverenju u državu da će u slučaju propasti banke država nadoknaditi klijentima njihov ulog.

Kada plaćamo on line usluge ili vršimo neku drugu transakciju kreditnim karticama, poklanjamo poverenje kompanijama koje posreduju u našem plaćanju (Mastercard, VISA i dr.) koje za to uzimaju određenu materijalnu nadoknadu. Čak i prilikom tradicionalnih oblika plaćanja gotovinom u papirnom novcu, mi dajemo papir na kome je ispisana vrednost za koju prodavac veruje da će mu biti isplaćena (ili garantovana) od strane vlade koja ju je štampala. Digitalno plaćanje zbog prisustva trećih strana (banke, kreditne kompanije i dr.) uvek je bilo moguće pratiti. I kod plaćanja gotovinom klijenti veruju bankama i kreditnim kompanijama koje rukovode platnim karticama, da imaju pouzdane baze podataka. I vlade država veruju da banke i kreditne kompanije vode baze podataka koje su tačne i pouzdane.

Baze podataka sadrže mnoštvo ličnih podataka, od npr. medicinske dokumentacije u domu zdravlja koja sadrži važne informacije o nama i našem zdravstvenom stanju, kada smo i od koje bolesti bolovali, koje lekove smo koristili i sl. I druge baze podataka sadrže mnoštvo naših ličnih podataka koje su važne ne samo za nas, već i za državu, grad, privredu, druge građane itd.

Osim što omogućava anonimne i sigurne transakcije, blokčejn ima i potencijal da sačuva sve vredne informacije, od podataka o rođenim i umrlim, preko osiguranja, do katastara nepokretnosti, pa čak i glasova (Tapscott, 2018).

Sagledavši mogućnosti koji blokčejn nudi u transformaciji industrija i tržišta, povećanju transparentnosti i poverenja između građana, kao i olakšanom pristupu tržištu (uz bolju efikasnost transakcija), ali i rizicima koje sa sobom nosi, Organizacija za ekonomsku saradnju i razvoj - OECD organizovala je od 4. do 5. septembra 2018. godine Forum politike OECD-a za blokčejn. To je bila ujedno i prva glavna međunarodna konferencija na kojoj se razmatrao uticaj blokčejna na aktivnosti vlada i javnih prioriteta. Forum se bavio prednostima i rizicima blokčejna za ekonomiju i društvo, pokušajem određivanja adekvatnog regulatornog pristupa, kao i javnih politika prema blokčejnu.

Učesnici Foruma su diskutovali o mogućnostima globalnog ekonomskog uticaja blokčejna, njegovim implikacijama na privatnost i sajber bezbednost, upotrebi blokčejn tehnologija za povećanje inkluzivnosti, njegovoj upotrebi u promovisanju zelenog rasta i održivosti, kao i jačanju kapaciteta javne uprava i primene u praksi (OECD, 2018).

4 ZAKLJUČAK

Pre bitkoina bilo je mnoštvo neuspelih pokušaja stvaranja digitalnih valuta (digikeš, heškeš, Fejsbuk kredit i dr.). Uspeh bitkoina leži u prednostima koje ima u odnosu na druge slične valute, ali njegov značaj prevazilazi i pogodnosti koje je doneo.

Svaki korisnik bitkoina ima potpunu kontrolu nad novcem na svom računu (adresi), jedino osoba sa privatnim ključem može pristupiti bitkoinima na toj adresi. Banke nisu potrebne za čuvanje podataka o novcu, evidenciju o imovini i svakoj transakciji bitkoina čuvaju računari svih korisnika mreže u zajedničkoj bazi podataka blokčejnu. Sve transakcije su mnogo brže od bankarskih, bez taksi, uz drastično lakše plaćanje preko državnih granica.

Bitkoin svojim korisnicima pruža bezbednosti bez identifikacije, iako blokčejn beleži transakciju, ne beleži ko stoji iza nje. Zahvaljujući peer-to-peer komunikaciji i kriptografiji, povezivanje bitkoin transakcija sa osobom u stvarnom životu je veoma teško. To je u ujedno možda i njegova najveća mana, jer su oporezivanje i nadzor nad korisnicima krajnje teški.

Garancija vrednosti bitkoina osmišljena je po uzoru na plamenite metale kojih ima ograničeno u prirodi. Zbog toga je Satoši u kodu bitkoina odredio da ih ima maksimalno 21 milion, te da ukoliko bitkoin protokol ostane isti, poslednji bitkoin će biti izrudaren 2140. godine.

Do sada je izrudareno oko 17 miliona bitkoina, što znači da je ostalo 4 miliona, ili oko 19%. Do sada je bitkoin uspeo da prevlada sve krize koje su ga zahvatile (u više slučajeva nestajali su iznosi koji su dostizali i 400 miliona dolara). Kakva god sudbina bitkoina bila u budućnosti, njegova uloga se neće moći zanemariti, prvenstveno zbog toga što je zahvaljujući njemu iznedren blokčejn. Bez obzira na skepticima u vezi sa kriptovalutama, teško se mogu osporiti mogućnosti koje blokčejn pruža, pre svega u zaštiti baza podatka.

Postoji sveto carstvo privatnosti za svakog čoveka gde on bira i pravi odluke – carstvo stvoreno na bazičnim pravima i slobode koje zakon, generalno, ne sme narušavati. Džefri Fišer, Arhiepiskop Canterberija (1959)

Pre ne toliko dugo, uobičajen režim interneta je bio neenkriptovan običan tekst (plain text). Svi su mogli špiunirati svakoga i mnogi nisu o tome ni razmišljali. Globalno obelodanjivanje nadzora 2013. je to promenilo i danas se koriste mnogo bezbedniji protokoli i end-to-end enkripcija postaje standard sve više. Iako bitcoin postaje tinejdžer, mi smo – metaforično govoreći – i dalje u dobu običnog teksta narandžastog novčića. Bitcoin je radikalno providljiv protokol sam po sebi, ali postoje značajni načini da korisnik zaštiti svoju privatnost. U ovom članku želimo da istaknemo neke od ovih strategija, prodiskutujemo najbolje prakse, i damo preporuke koje mogu primeniti i bitcoin novajlije i veterani.

Zašto je privatnost bitna

Privatnost je potrebna da bi otvoreno društvo moglo da funkcioniše u digitalnoj eri. Privatnost nije isto što i tajanstvenost. Privatna stvar je nešto što neko ne želi da ceo svet zna, a tajna stvar je nešto što neko ne želi bilo ko da zna. Privatnost je moć da se čovek selektivno otkriva svom okruženju.

Ovim snažnim rečima Erik Hjus je započeo svoj tekst Sajferpankov Manifesto (Cypherpunk's Manifesto) 1993. Razlika između privatnosti i tajanstvenosti je suptilna ali jako važna. Odlučiti se za privatnost ne znači da neko ima tajne koje želi sakriti. Da ovo ilustrujemo shvatite samo da ono što obavljate u svom toaletu ili u spavaćoj sobi nije niti ilegalno niti tajna (u mnogim slučajevima), ali vi svejedno odlučujete da zatvorite vrata i navučete zavese.

Slično tome, koliko para imate i gde ih trošite nije naručito tajna stvar. Ipak, to bi trebalo biti privatan slučaj. Mnogi bi se složili da vaš šef ne treba da zna gde vi trošite vašu platu. Privatnosti je čak zaštićena od strane mnogobrojnih internacionalnih nadležnih organa. Iz Američke Deklaracije Prava i Dužnosti Čoveka (American Declaration of the Rights and Duties of Man) Ujedinjenim Nacijama, napisano je da je privatnost fundamentalno prava gradjana širom sveta.

Niko ne sme biti podvrgnut smetnjama njegovoj privatnosti, porodici, rezidenciji ili komunikacijama, niti napadnuta njegova čast i reputacija. Svi imaju pravo da se štite zakonom protiv takvih smetnja ili napada. Artikal 12, Deklaracija Ljudskih Prava Ujedinjenih Nacija

Bitcoin i privatnost

Iako je bitcoin često opisivan kao anoniman način plaćanja medijima, on u stvari poseduje potpuno suprotne osobine. On je poluanoniman u najboljem slučaju i danas mnogima nije ni malo lako primeniti taktike da bi bili sigurni da njihov poluanonimni identitet na bitcoin mreži ne bude povezan sa legalnim identitetom u stvarnom svetu.

Bitcoin je otvoren sistem. On je javna baza podataka koju svako može da proučava i analizira. Znači, svaka transakcija koja je upisana u tu bazu kroz dokaz rada (proof-of-work) postojaće i biće otkrivena dokle god bitcoin postoji, što znači - zauvek. Ne primenjivati najbolje prakse privatnosti može imati štetne posledice u dalekoj budućnosti.

Privatnost, kao sigurnost, je proces koji je težak, ali nije nemoguć. Alatke nastavljaju da se razvijaju koje čuvaju privatnost kad se koristi bitcoin and srećom mnoge od tih alatki su sve lakše za korišćenje. Nažalost ne postoji panacea u ovom pristupu. Mora se biti svesan svih kompromisa i usavršavati te prakse dok se one menjaju.

Najbolje prakse privatnosti

Kao i sve u bitcoinu, kontrola privatnosti je postepena, korak po korak, procedura. Naučiti i primeniti ove najbolje prakse zahteva strpljivost i odgovornost, tako da ne budite obeshrabreni ako vam se čini da je to sve previše. Svaki korak, koliko god bio mali, je korak u dobrom pravcu.

Koje korake preduzeti da bi uvećali svoju privatnost:

• Budite u vlasništvu sami svojih novčića
• Nikad ne ponavljajte korišćenje istih adresa
• Minimizirajte korišćenje servisa koji zahtevaju identitet (Know your customer - KYC)
• Minimizirajte sve izloženosti trećim licima
• Upravljajte svojim nodom
• Koristite Lightning mrežu za male transakcije
• Nemojte koristiti javne blok pretraživače za svoje transakcije
• Koristite metodu CoinJoin često i rano pri nabavljanju svojih novčića

Budite u vlasništvu sami svojih novčića: Ako ključevi nisu tvoji, onda nije ni bitcoin. Ako neko drugo drži vaš bitcoin za vas, oni znaju sve što se može znati: količinu, istoriju transakcija pa i sve buduće transakcije, itd. Preuzimanje vlasništva bitcoina u svoje ruke je prvi i najvažniji korak.

Nikad ne kroistite istu adresu dvaput: Ponavljanje adresa poništava privatnost pošiljalca i primaoca bitcoina. Ovo se treba izbegavati pod svaku cenu.

Minimizirajte korišćenje servisa koji zahtevaju identitet (KYC): Vezivati svoj legalni identitet za svoje bitcoin adrese je zlo koje se zahteva od strane mnogih državnih nadležnosti. Dok je efektivnost ovih zakona i regulacija disputabilno, posledice njihovog primenjivanja su uglavnom štetne po korisnicima. Ovo je očigledno pošto je česta pojava da se te informacije često izlivaju iz slabo obezbeđenih digitalnih servera. Ako izaberete da koristite KYC servise da bi nabavljali bitcoin, proučite i razumite odnos između vas i tog biznisa. Vi ste poverljivi tom biznisu za sve vaše lične podatke, pa i buduće obezbeđenje tih podataka. Ako i dalje zarađujete kroz fiat novčani sistem, mi preporučujemo da koristite samo bitcoin ekskluzivne servise koji vam dozvoljavaju da autamatski kupujete bitcoin s vremena na vreme. Ako zelite da potpuno da izbegnete KYC, pregledajte https://bitcoinqna.github.io/noKYConly/.

Minimizirajte sve izloženosti trećim licima: Poverljivost trećim licima je bezbednosna rupa (https://nakamotoinstitute.org/trusted-third-parties/). Ako možete biti poverljivi samo sebi, onda bi to tako trebalo da bude.

Upravljajte svojim nodom: Ako nod nije tvoj, onda nisu ni pravila. Upravljanje svojim nodom je suštinska potreba da bi se bitcoin koristio na privatan način. Svaka interakcija sa bitcoin mrežom je posrednjena nodom. Ako vi taj nod ne upravljate, čiji god nod koristite može da vidi sve što vi radite. Ova upustva (https://bitcoiner.guide/node/) su jako korisna da bi započeli proces korišćenja svog noda.

Koristite Lightning mrežu za male transakcije: Pošto Lightning protokol ne koristi glavnu bitcoin mrežu za trasakcije onda je i samim tim povećana privatnost korišćenja bez dodatnog truda. Iako je i dalje rano, oni apsolutno bezobzirni periodi Lightning mreže su verovatno daleko iza nas. Korišćenje Lightning-a za transakcije malih i srednjih veličina će vam pomoći da uvećate privatnost a da smanjite naplate svojih pojedinačnih bitcoin transakcija.

Nemojte koristiti javne blok pretraživače za svoje transakcije: Proveravanje adresa na javnim blok pretraživačima povezuje te adrese sa vašim IP podacima, koji se onda mogu koristiti da se otkrije vaš identitet. Softveri kao Umbrel i myNode vam omogućavaju da lako koristite sami svoj blok pretraživač. Ako morate koristiti javne pretraživače, uradite to uz VPN ili Tor.

Koristite CoinJoin često i rano pri nabavljanju svojih novčića: Pošto je bitcoin večan, primenjivanje saradničkih CoinJoin praksa će vam obezbediti privatnost u budućnosti. Dok su CoinJoin transakcije svakovrsne, softveri koji su laki za korišćenje već sad postoje koji mogu automatizovati ovu vrstu transakcija. Samourai Whirlpool (https://samouraiwallet.com/whirlpool) je odličan izbor za Android korisnike. Joinmarket (https://github.com/joinmarket-webui/jam) se može koristiti na vašem nodu. A servisi postoje koji pri snabdevanju vašeg bitcoina istog trenutka obave CoinJoin tranzakciju automatski.

Zaključak

Svi bi trebalo da se potrude da koriste bitcoin na što privatniji način. Privatnost nije isto što i tajanstvenost. Privatnost je ljudsko pravo i mi svi trebamo da branimo i primenljujemo to pravo. Teško je izbrisati postojeće informacije sa interneta; a izbrisati ih sa bitcoin baze podataka je nemoguće. Iako su daleko od savršenih, alatke postoje danas koje vam omogućavaju da najbolje prakse privatnosti i vi sami primenite. Mi smo vam naglasili neke od njih i - kroz poboljšanje u bitcoin protokolu kroz Taproot i Schnorr - one će postajati sve usavršenije.

Bitcoin postupci se ne mogu lako opisati korišćenjem tradicionalnim konceptima. Pitanja kao što su "Ko je vlasnik ovog novca?" ili "Odakle taj novac potiče?" postaju sve teža da se odgovore a u nekim okolnostima postaju potpuno beznačajna.

Satoši je dizajnirao bitcoin misleći na privatnost. Na nivou protokola svaka bitcoin transakcija je proces "topljenja" koji za sobom samo ostavlja heuristične mrvice hleba. Protokolu nije bitno odakle se pojavio bilo koji bitcoin ili satoši. Niti je njega briga ko je legalan identitet vlasnika. Protokolu je samo važno da li su digitalni potpisi validni. Dokle god je govor slobodan, potpisivanje poruka - privatno ili ne - ne sme biti kriminalan postupak.

Here’s Sean Voisen writing about how programming is a feeling:

For those of us who enjoy programming, there is a deep satisfaction that comes from solving problems through well-written code, a kind of ineffable joy found in the elegant expression of a system through our favorite syntax. It is akin to the same satisfaction a craftsperson might find at the end of the day after toiling away on well-made piece of furniture, the culmination of small dopamine hits that come from sweating the details on something and getting them just right. Maybe nobody will notice those details, but it doesn’t matter. We care, we notice, we get joy from the aesthetics of the craft.

This got me thinking about the idea of satisfaction in craft. Where does it come from?

Bitcoineri, od programera Bitcoin Core-a preko dugogodišnjih entuzijasta Bitcoina do nedavnih pronalazača /r/Bitcoina, vole razgovarati o tome kako je decentralizacija Bitcoina njegova ultimativna značajka. Doduše, rijetko vidite da netko objašnjava zašto je decentralizacija važna. Zasigurno je to zanimljiva značajka iz perspektive računalne znanosti, no zašto bi potrošači, tvrtke ili investitori marili za to? Ova objava je pokušaj da se napiše zašto je decentralizacija temelj vrijednosti Bitcoina i što je još važnije, postavi buduće objave u kojima se govori o tome kada ona to nije.

Kada Bitcoineri govore o decentralizaciji Bitcoina, prva stvar koja se pojavljuje je često spominjani nedostatak inherentnog povjerenja u treću stranu. Dok je dobro postavljeno povjerenje preduvjet za učinkovit rad mnogih sustava, jednom kada se takvo povjerenje izgubi, sustavi mogu postati nevjerojatno krhki. Uzmimo, za primjer, povjerenje u američke banke prije uspostave FDIC-a (Federal Deposit Insurance Corporation). Dok je pristup bankovnim uslugama omogućio više pogodnosti i mnogim tvrtkama učinkovitije poslovanje, poznato je da su banke propadale, pritom upropaštavajući sa sobom sva sredstva klijenata. Dok je predstavljanje FDIC-a i sličnih programa decentraliziralo povjerenje u financijske institucije s jedne strane na dvije, transakcije u velikom dijelu svijeta ne nude takvu zaštitu. Čak i uz takve programe, pojedinci nisu univerzalno zaštićeni od gubitka preko granica i preko određene vrijednosti.

U novije vrijeme, propisi koji dopuštaju pojedinim državnim dužnosnicima jednostrano oduzimanje imovine postali su uobičajeni. Naročito u SAD-u, sada zloglasna “Operacija Choke Point” i programi oduzimanja civilne imovine, omogućili su službenicima za provođenje zakona i privatnim institucijama da zapljenjuju financijsku imovinu i uskraćuju financijske usluge uz malo ili nimalo nadzora. Uklanjanje provjerenih skrbnika i stvaranje sustava s likvidnom imovinom, koja se ne može zaplijeniti, ima potencijal pružiti pouzdanije financijske usluge mnogima koji inače ne bi mogli djelovati učinkovito ili uopće ne bi mogli djelovati. Ova mogućnost da se Bitcoin ne može zaplijeniti, omogućena je samo zbog nedostatka za centraliziranim povjerenjem. Centralizirani sustavi elektroničke gotovine i financijski sustavi su pokušali pružiti takvu pouzdanost, propisi i poslovna stvarnost su to gotovo univerzalno spriječili.

Svojstvo koje je jednako važno za sposobnost Bitcoina da pruža financijske usluge zviždačima, stranim disidentima i porno zvijezdama je njegov otpor cenzuri transakcija. Sposobnost trećih strana da zaplijene imovinu rezultira izravnim i čistim novčanim gubitkom, zamrzavanje imovine može imati sličan učinak. Kada pojedinac ili organizacija više nisu u mogućnosti obavljati transakcije za plaćanje roba i usluga, njihova financijska imovina brzo gubi vrijednost. Iako Bitcoin ima vrlo dobru priču o nemogućnosti zapljene (svaka strana u sustavu nameće nemogućnost bilo koga da potroši Bitcoin bez dodanog privatnog ključa), njegova priča o otporu cenzuri je malo utančanija.

U svijetu u kojem nijedan rudar Bitcoina nema više od 1% ukupne hash snage (ili nešto drugo što je jednako decentralizirano), trebalo bi biti lako pronaći rudara koji je ili anoniman i prihvaća sve transakcije ili je u nadležnosti koja ne pokušava cenzurirati vaše transakcije. Naravno, ovo nije svijet kakav danas imamo, a cenzura transakcija jedan je od većih razloga da se ozbiljno zabrinemo centralizacijom rudarenja (za pune čvorove). Ipak, mogućnost pojedinca da kupi hash snagu (u obliku lako dostupnog starog hardvera ili u obliku njegovog iznajmljivanja) za rudarenje svoje inače cenzurirane transakcije, opcija je sve dok je pravilo najdužeg lanca na snazi ​​kod svih rudara. Iako je znatno skuplji nego što bi bio u istinski decentraliziranom Bitcoinu, to omogućuje Bitcoinu da zadrži neka od svojih anti-cenzuriranih svojstava.

Ako ste već dovoljno dugo u priči oko Bitcoina, možda ćete prepoznati gornja svojstva kao kritična za zamjenjivost. Zamjenjivost, kao ključno svojstvo svakog monetarnog instrumenta, odnosi se na ideju da vrijednost jedne jedinice treba biti ekvivalentna svakoj drugoj jedinici. Bez mogućnosti odmrzavanja/otpora cenzuri i nemogućnosti zapljene, Bitcoin (i svaki drugi monetarni sustav) počinje gubiti zamjenjivost. Trgovci i platni procesori više ne mogu razumno prihvaćati Bitcoin bez provjere niza crnih lista i mnogo truda kako bi bili sigurni da će moći potrošiti Bitcoin koji prihvaćaju. Ako povjerenje u zamjenjivost Bitcoina deformira, njegova bi korist mogla biti značajno deformirana.

Još jedno svojstvo koje proizlazi iz decentralizacije Bitcoina, je njegov otvoreni pristup. Ulagači iz Silicijske doline često ga nazivaju jednim od najzanimljivijih svojstava Bitcoina, a mnogi ga vole nazivati ​​"bez dopuštenja". Sposobnost bilo koga, bilo gdje u svijetu, sa internetskom vezom, da prihvaća Bitcoin za robu i usluge i koristi Bitcoin za kupnju roba i usluga je vrlo uzbudljiva. Opet, ovo svojstvo ovisi o decentralizaciji Bitcoina. Iako postoje mnogi centralizirani pružatelji financijskih usluga, gdje mnogi od njih promoviraju svoju dostupnost bilo kome, sama njihova prisutnost kao centraliziranog tijela koje može proizvoljno uskratiti uslugu, čini ih podložnim budućim promjenama politike iz bilo kojeg razloga. PayPal je, na primjer, utemeljen na idealima univerzalnog pristupa elektroničkoj gotovini. Međutim, zbog svoje pozicije središnje vlasti, brzo je promijenio svoje politike, kako bi udovoljio pritiscima regulatora i politikama postojećeg financijskog sustava na koji se oslanjao. Ovih dana, PayPal je nadaleko poznat po zamrzavanju računa i oduzimanju imovine uz malo ili nimalo upozorenja. U osnovi, oslanjanje na centralizirane strane za usluge nije kompatibilno s univerzalnim otvorenim pristupom u financijskom svijetu.

Primijetit ćete da se sve gore navedene kritične značajke, one koje Bitcoin čine tako uzbudljivim za sve nas, centralizirani sistemi već neko vrijeme mogu implementirati. Zapravo to se radilo i prije, u učinkovitijim sustavima od Bitcoina. Naravno, nikada nisu potrajali, gubeći kritična svojstva nakon podešavanja kako bi se popravila ova ili ona stvar, implementirajući regulatorne sustave cenzure izravno u osnovne slojeve, ograničavajući pristup rastu dobiti i potpuno gašenje. Stvarno, decentralizacija u Bitcoinu sama po sebi nije značajka, već je umjesto toga jedini način za koji znamo da održimo značajke koje želimo u sustavima kojima upravljaju ljudi.

Album art didn’t always exist. In the early 1900s, recorded music was still a novelty, overshadowed by sales of sheet music. Early vinyl records were vastly different from what we think of today: discs were sold individually and could only hold up to four minutes of music per side. Sometimes, only one side of the record was used. One of the most popular records of 1910, for example, was “Come, Josephine, in My Flying Machine”: it clocked in at two minutes and 39 seconds.

The invention of album art can get lost in the story of technological mastery. But among all the factors that contributed to the rise of recorded music, it stands as one of the few that was wholly driven by creators themselves. Album art — first as marketing material, then as pure creative expression — turned an audio-only medium into a multi-sensory experience.

This is the story of the people who made music visible.

"Kleines Erste-Hilfe-Büchlein gegen Propaganda" von 2023. „Normalerweise hört man das Wort „Propaganda“ im Mainstream-Diskurs nur, wenn es um Dinge geht, die andere Länder ihren eigenen Bürgern antun oder Teil ausländischer Beeinflussungsoperationen sind, obwohl in der überwältigenden Mehrheit der Fälle, in denen wir in unserem täglichen Leben Propaganda erlebt haben, der Anruf aus dem eigenen Haus kam.“

https://soundcloud.com/radiomuenchen/helge-buttkereit-medienkritik-als-trotziger-idealismus?

In der Folge dokumentiert sie einige gravierende Beispiele aus den US-Medien. Auch in Deutschland fehlt es den Massenmedien an der nötigen Distanz zur Regierung und ihrem Werte-Narrativ. Was umso gefährlicher ist, da sie über „Definitionsmacht“ verfügen. Auch wenn wir selbst diese Medien nicht konsumieren, so können wir doch sicher sein, dass die große Mehrheit der Bürger sie konsultiert und damit deren Sicht auf die Welt massiv beeinflusst wird. „Wenn wir die Tagesschau einschalten, erfahren wir nichts über die ‘Wirklichkeit’. Wir lernen vielmehr, wer es geschafft hat, seine Sicht auf die Wirklichkeit in die Propaganda-Matrix einzuschreiben“, verrät der Medienwissenschaftler Michael Meyen in seinem Buch "Die Propaganda-Matrix". Nun gilt jedoch die Presse in der öffentlichen Wahrnehmung als „Vierte Gewalt“ der Demokratie. Ihre Aufgabe wäre es demnach, die zunehmend verflochtenen Staatsgewalten Legislative, Exekutive und Judikative zu kontrollieren. Die Realität sieht anders aus. Dabei übersieht selbst die immer häufiger auftretende Medienkritik, dass die „Vierte Gewalt“ von den Herrschenden nie in dieser Funktion gedacht war – schließlich waren und sind die Medien seit je her in den Händen von Regierungen und Konzernen, schreibt unser Autor Helge Buttkereit.

I don’t like garlic. It’s not a dislike for the taste in the moment, so much as an extreme dislike for the way it stays with you—sometimes for days—after a particularly garlicky meal.

Interestingly enough, both of my brothers love garlic. They roast it by itself and keep it at the ready so they can have a very strong garlic profile in their cooking. When I prepare a dish, I don’t even see garlic on the ingredient list. I’ve cut it out of my life so completely that my brain genuinely skips over it in recipes. While my brothers are looking for ways to sneak garlic into everything they make, I’m subconsciously avoiding it altogether.

A few years back, when I was digging intensely into how design systems mature, I stumbled on the concept of a design system origin story. There are two extreme origin stories and an infinite number of possibilities between. On one hand you have the grassroots system, where individuals working on digital products are simply trying to solve their own daily problems. They’re frustrated with having to go cut and paste elements from past designs or with recreating the same layouts over and over, so they start to work more systematically. On the other hand, you have the top down system, where leadership is directing teams to take a more systematic approach, often forming a small partially dedicated core team to tackle some centralized assets and guidelines for all to follow. The influences in those early days bias a design system in interesting and impactful ways.

We’ve established that there are a few types of bias that are either intentionally or unintentionally embedded into our design systems. Acknowledging this is a great first step. But, what’s the impact of this? Does it matter?

I believe there are a few impacts design system biases, but there’s one that stands out. The bias in your design system makes some individuals feel the system is meant for them and others feel it’s not. This is a problem because, a design system cannot live up to it’s expected value until it is broadly in use. If individuals feel your design system is not for them, the won’t use it. And, as you know, it doesn’t matter how good your design system is if nobody is using it.

I've been eager to share my thoughts on "Return of the Strong Gods" by R.R. Reno since I finished it a week ago.

I found this book incredibly insightful. @SimpleStacker's excellent review prompted me to pick it up, and I'm glad I did. While I won't be providing a full review, I will share some of the key insights and thoughts that resonated with me.

Reno masterfully dissects the sociological underpinnings of the political shifts in the US and the Western world over the past decade and a half. His analysis of the rise of populism and nationalism is compelling and rings true to my personal observations. Reno's central thesis is that post-WW2, the West embraced "weaker gods"—ideals like democracy, pluralism, and liberalism—fearing a repeat of the strong nationalistic sentiments that led to Hitler's rise. He argues that this shift has left many people feeling culturally homeless and desperate for strong leadership that listens to their grievances.

A significant portion of Reno's argument is built on the ideas of Karl Popper, a philosopher I was unfamiliar with before reading this book. Popper's work "The Open Society and Its Enemies" has significantly influenced post-war consensus, which Reno argues has led to a disconnect between the political elite and the common people. This disconnect, he posits, is a primary driver of populist sentiments.

Reno also delves into economics, discussing Friedrich Hayek and his agreement with some of Popper's positions. This intersection of philosophy and economics provides a unique lens through which to view the political landscape. Reno's mention of the Treaty of Versailles as a catalyst for Hitler's rise is a point often overlooked in discussions about WW2. He argues that the punitive measures imposed on Germany created an environment ripe for a strongman to emerge.

One of the most compelling aspects of Reno's argument is his explanation of how the political elite often lose touch with the values and wishes of the people they represent. He draws a powerful analogy between cultural homelessness and the desperation that drives people to seek strong leadership. This section of the book particularly resonated with me, as it aligns with my own observations of the political climate.

I would have liked Reno to start his analysis with Woodrow Wilson, whose "making the world safe for democracy" slogan embodied a form of Christian nationalism. Wilson's ideals and the post-WW1 environment laid the groundwork for the open society movement, which Reno critiques. Exploring this historical context could have strengthened Reno's argument.

Reno occasionally conflates economic liberalism with libertinism, which I found to be a minor flaw in an otherwise strong argument. He rightly points out the need for moral ethics in society but seems to overlook the distinction between economic freedom and moral laxity. Reno's discussion of Milton Friedman's ideas further highlights this confusion. While Reno argues that free trade has contributed to many of our modern ills, I believe the issue lies more with nation-state trade agreements like NAFTA, which are not true examples of free trade.

Another area where I disagree with Reno is his conflation of the nation with the state. Nations are cultural entities that predate and can exist independently of states. Reno's argument would be stronger if he acknowledged this distinction, as it would clarify his points about national pride and cultural heritage.

Reno's final chapters offer a cautionary tale about the return of strong gods and the danger of making them idols. He warns against authoritarianism and the overreach of the state, advocating for a balance that respects cultural heritage without succumbing to nationalism.

In conclusion, "Return of the Strong Gods" is a thought-provoking exploration of the political and cultural shifts of our time. Reno's insights are valuable, and his arguments, while not without flaws, provide a fresh perspective on the rise of populism and nationalism. I recommend this book to anyone seeking a deeper understanding of the forces shaping our world today.

Hi frens, you may or may not have noticed I’ve been MIA for about three weeks. I wanted to take a moment to explain where I’ve been, and why I stepped back for a bit.

At the start of the year, I was determined to make the most of it-and I still am. I’ve been pouring myself into several projects, especially my painting, which has really taken off. I’m so grateful for your support; none of this would be possible without you. But here’s where things got tricky. I started feeling like I had to “earn” every moment of rest, and that mindset snowballed. My health took a hit, and then one of my other projects completely derailed.

The stress piled up, and I felt like I was on the verge of burning out.

Don’t get me wrong-I’ve always welcomed change, even when it’s tough. And this time was no exception. The project I’d been working on for months took a 180, and all that effort seemed to go down the drain. I was frustrated, but I kept pushing, even though I was running on fumes. By the time I “earned” a break, I was too exhausted to enjoy it.

I managed to post a piece about Holy Week on my blog (which I’m really proud of-check it out if you haven’t!), but after that, I was done. I realized I needed to stop, not just for a day, but for a real break. When I finally took a few days off with my husband, it was clear how much I needed it. I was burned out, plain and simple. Now, I’m still putting myself back together. Mentally, I feel drained, but I’m stronger than I was a few weeks ago. I know I’m lucky and privileged to be able to take this time, and I’m grateful for the perspective it’s given me. I also r realize that this isn’t just a “me” thing-most people have been here at some point. We keep going until there’s nothing left, then wonder why we feel like empty shells.

I’ll be back to drawing soon (knock on wood-don’t want to jinx it!). In the meantime, take care of yourselves, and godspeed.

A francia székhelyű Newcleo, az olasz dizájncég Pininfarina és az olasz hajógyártó Fincantieri bemutatták a TL-40 nevű, következő generációs, hajókra szánt nukleáris reaktor teljes méretű modelljét a 19. Velencei Építészeti Biennálén[1][2][5][6][7].

A TL-40 reaktor főbb jellemzői

• IV. generációs, ólom-hűtésű kis moduláris reaktor (SMR), amelyet nagy hajók meghajtására fejlesztettek ki[1][2][5][6].
• Kompakt, biztonságos és fenntartható: A reaktor passzív biztonsági rendszereket alkalmaz, amelyek a fizika törvényein keresztül kizárják a nukleáris balesetek lehetőségét[2][5][6].
• Nukleáris hulladék újrahasznosítása: A TL-40 képes újrafeldolgozott nukleáris hulladékot üzemanyagként használni, ezzel egyszerre járul hozzá az energiatermeléshez és a hulladékcsökkentéshez[1][2][5][6].
• Formatervezés és ipari háttér: A Pininfarina gondoskodott a dizájnról és a reaktor esztétikai megjelenéséről, míg a Fincantieri a hajógyártási tapasztalatát adta hozzá[1][2][5][6][7].
• Nyitott konfiguráció: A reaktor vázája lehetővé teszi a látogatók számára, hogy belülről is megismerjék a technológiát, interaktív módon[1][2][5].

Technológiai és környezeti jelentőség

• Dekarbonizáció: A fejlesztés célja, hogy a nukleáris energiát a hajózás szektorában is a szén-dioxid-kibocsátás csökkentésének eszközeként alkalmazzák[1][2][5][6].
• Európai hulladék hasznosítása: A jelenleg Európában tárolt nukleáris hulladék elegendő lenne a kontinens villamosenergia-igényének fedezésére évszázadokon át, ha ilyen típusú reaktorokban hasznosítanák[2][5][6].
• Kreatív szemlélet: A projekt célja a nukleáris energia társadalmi megítélésének javítása, bemutatva, hogy az lehet egyszerre biztonságos, esztétikus és fenntartható[1][5][6][7].

Együttműködés és jövőbeli tervek

• Folyamatos együttműködés: A Newcleo és a Fincantieri 2023 óta dolgoznak együtt a tengeri alkalmazások fejlesztésén[2][5][6][7].
• Kutatás-fejlesztés: A Pininfarina a Newcleo franciaországi (Chusclan) nukleáris üzemanyag kutató-fejlesztő központjának tervezésében is részt vesz[2][5][6][7].
• Első demonstrációs reaktor: A Newcleo célja, hogy 2031-re bemutassa az első demonstrációs reaktort, 2033-ra pedig kereskedelmi forgalomba hozza azt[8].
• Földi alkalmazás: A vállalat már megkezdte a földi, ólom-hűtésű LFR-AS-30 reaktor telephelyének előkészítését Franciaországban (Chinon régió)[8].
• Európai támogatás: Az LFR dizájn 2024 októberében felkerült az Európai Ipari Szövetség támogatásra javasolt SMR-listájára[8].

Idézetek a projekt vezetőitől

„Ez nem a nagyapáink reaktora. Fenntartható, előremutató technológia, amely a való világ és a klímaváltozás kihívásaira készült.”
(Stefano Buono, a Newcleo vezérigazgatója)[1][5][6][7]

„A dizájn stratégiai szerepet játszik a fenntartható energia megoldások fejlesztésében, biztosítva a társadalmi és környezeti szempontok teljes integrációját az innovációs folyamat során.”
(Silvio Angori, a Pininfarina vezérigazgatója)[6][7]

Someone asked for my thoughts, so I’ll share them thoughtfully. I’m not here to dictate how to promote Nostr—I’m still learning about it myself. While I’m not new to Nostr, freedom tech is a newer space for me. I’m skilled at advocating for topics I deeply understand, but freedom tech isn’t my expertise, so take my words with a grain of salt. Nothing I say is set in stone.

Those who need Nostr the most are the ones most vulnerable to censorship on other platforms right now. Reaching them requires real-time awareness of global issues and the dynamic relationships between governments and tech providers, which can shift suddenly. Effective Nostr promoters must grasp this and adapt quickly.

The best messengers are people from or closely tied to these at-risk regions—those who truly understand the local political and cultural dynamics. They can connect with those in need when tensions rise. Ideal promoters are rational, trustworthy, passionate about Nostr, but above all, dedicated to amplifying people’s voices when it matters most.

Forget influencers, corporate-backed figures, or traditional online PR—it comes off as inauthentic, corny, desperate and forced. Nostr’s promotion should be grassroots and organic, driven by a few passionate individuals who believe in Nostr and the communities they serve.

The idea that “people won’t join Nostr due to lack of reach” is nonsense. Everyone knows X’s “reach” is mostly with bots. If humans want real conversations, Nostr is the place. X is great for propaganda, but Nostr is for the authentic voices of the people.

Those spreading Nostr must be so passionate they’re willing to onboard others, which is time-consuming but rewarding for the right person. They’ll need to make Nostr and onboarding a core part of who they are. I see no issue with that level of dedication. I’ve been known to get that way myself at times. It’s fun for some folks.

With love, I suggest not adding Bitcoin promotion with Nostr outreach. Zaps already integrate that element naturally. (Still promote within the Bitcoin ecosystem, but this is about reaching vulnerable voices who needed Nostr yesterday.)

To promote Nostr, forget conventional strategies. “Influencers” aren’t the answer. “Influencers” are not the future. A trusted local community member has real influence—reach them. Connect with people seeking Nostr’s benefits but lacking the technical language to express it. This means some in the Nostr community might need to step outside of the Bitcoin bubble, which is uncomfortable but necessary. Thank you in advance to those who are willing to do that.

I don’t know who is paid to promote Nostr, if anyone. This piece isn’t shade. But it’s exhausting to see innocent voices globally silenced on corporate platforms like X while Nostr exists. Last night, I wondered: how many more voices must be censored before the Nostr community gets uncomfortable and thinks creatively to reach the vulnerable?

A warning: the global need for censorship-resistant social media is undeniable. If Nostr doesn’t make itself known, something else will fill that void. Let’s start this conversation.

Vrijednost Bitcoina po prvi put je premašila 100.000 dolara. Ova kriptovaluta svoj masovni rast može na neki način zahvaliti reizboru Donalda Trumpa za američkog predsjednika. On je najavio blaži regulatorni pristup kripto industriji.

Što je Bitcoin?

Bitcoin (BTC) je kriptovaluta (virtualna valuta) dizajnirana da djeluje kao novac i oblik plaćanja izvan kontrole bilo koje osobe, grupe ili entiteta. Time nema potrebe za sudjelovanjem pouzdane treće strane npr. kovnice novca ili banke u financijskim transakcijama. Osoba ili grupa pod pseudonimom Satoshi Nakamoto 31. listopada 2008. objavila je tehnički dokument pod nazivom "Bitcoin: Peer-to-Peer Electronic Cash System". Taj je dokument distribuiran na kriptografsku mailing listu, samo mjesec dana nakon što je investicijska banka Lehman Brothers podnijela zahtjev za najveći bankrot u povijesti SAD-a, a vlada odobrila financijsku pomoć od 700 milijardi dolara.

Nekoliko mjeseci kasnije, 3. siječnja 2009., Bitcoin mreža pokrenula se, uvodeći novi sustav decentralizirane digitalne valute bez središnjeg posrednika.

Tko su osnivači Bitcoina?

Bitcoin je rezultat desetljeća razvoja kriptografije i ideja Cypherpunka iz 1970-ih, s projektima poput B-money, Bit Gold, eCash i HashCash.

Godine 2006., osoba ili grupa pod pseudonimom Satoshi Nakamoto započela je rad na Bitcoinu. Iako su kriptografi poput Hal Finneya, Nicka Szaba, Weija Daija i Adama Backa povezivani sa Satoshijem, svi su to negirali.

Satoshi je surađivao s programerima do 2010., kada je predao kontrolu nad izvornim kodom i 2011. nestao iz javnosti. Danas stotine programera razvijaju Bitcoin, koji ima zajednicu od milijun korisnika.

Kako funkcionira Bitcoin?

Bitcoin se može brzo i sigurno prenijeti na svakoga s Bitcoin adresom poput računa bilo gdje u svijetu, bez potrebe za dopuštenjem ili plaćanjem nepotrebnih naknada. BTC je jedinica valute u Bitcoin sustavu za koju postoji ograničena količina od 21 milijun. Svaki je Bitcoin djeljiv na 100 milijuna "satoshis" ili "sats" – najmanja jedinica Bitcoina, poput centa u dolaru. Bitcoini djeluju kao elektronički novac, omogućujući vam da izvršite plaćanje s univerzalnom valutom bilo gdje. Nalazi se u tzv. novčanicima u digitalnoj verziji. On funkcionira slično kao bankovni račun. Transakcije su moguće zahvaljujući peer-to-peer mreži. Osigurane su sustavom kriptografije javnog i privatnog ključa, objašnjava Kriptomat.

Bitcoin koristi kriptografiju javnog i privatnog ključa za sigurne transakcije. Javna adresa, izvedena iz "hasha" javnog ključa, koristi se za primanje sredstava. Privatni ključ služi kao digitalni potpis odnosno svojevrsna lozinka za autorizaciju transakcija i omogućava pristup sredstvima, pa ga treba čuvati u tajnosti.

Korisnik pokreće transakciju unosom javne adrese primatelja u svoj novčanik. Novčanik koristi privatni ključ za stvaranje digitalnog potpisa, čime se transakcija ovjerava i šalje na Bitcoin mrežu. Transakcija prvo ulazi u "mempool", gdje čeka potvrdu. Svakih desetak minuta, transakcije se grupiraju u blokove, koji se dodaju na blockchain, stvarajući neprekinuti lanac sigurnih zapisa.

Sigurnost sustava je toliko snažna da bi hakiranje jedne adrese trajalo milijardama godina.

Blockchain

Bitcoin je revolucionarno riješio problem dvostruke potrošnje, omogućujući prijenos sredstava izravno između korisnika bez posrednika. Zamislite mrežu stranaca, gdje svaki vodi vlastitu knjigu računa. Kada netko prenese 1 BTC, svi zapisuju transakciju i uspoređuju bilješke. Ako se sve podudaraju, transakcija se potvrđuje. Ako netko pokuša prevariti, njegova bilješka se odbacuje.

Ovaj sustav knjiga računa, distribuiran na globalnoj mreži, čini osnovu Bitcoin blockchaina. Svaki čvor ima identičnu kopiju koja javno i pseudonimno bilježi sve transakcije, osiguravajući točnost i sigurnost bez potrebe za skupim posrednicima.

Zašto je Bitcoin jedinstven i što mu daje vrijednost?

Bitcoin je revolucionirao digitalni novac stvaranjem decentraliziranog, sigurnog i otpornog sustava bez potrebe za posrednicima. Njegov kod omogućuje daljnje inovacije, a povremeno dolazi do "račvanja" koje stvara nove kriptovalute temeljene na Bitcoinu, iako one nikada ne mogu biti isti Bitcoin.

Njegova ključna snaga leži u decentralizaciji – nema središnje figure niti točke neuspjeha. Bitcoin se pokazao kao otporan na izazove, uključujući državne zabrane i snažna račvanja, što dodatno učvršćuje njegovu dugovječnost prema Lindyjevom efektu. Mrežni učinak potiče sve više korisnika da ga prihvate kao sredstvo za pohranu vrijednosti i razmjenu.

Njegova ograničena ponuda od 21 milijun BTC-a stvara oskudicu, čime se suprotstavlja inflacijskim valutama. Bitcoin je zamjenjiv, djeljiv na 100 milijuna dijelova, izdržljiv i prenosiv, što ga čini praktičnijim od zlata. S rastućim prihvaćanjem od strane tvrtki diljem svijeta, njegova vrijednost i korisnost nastavljaju rasti.

Blokovi, rudarenje i nagrade

Prvi Bitcoinblock izrudiran je 3. siječnja 2009. godine. Nazvan je Blok 0. Rudarenje Bitcoina je utrka između rudara za raspršivanje specifičnih vrijednosti i drugih informacija o bloku kako bi se pronašlo rješenje za problem raspršivanja i dodalo blok u blockchain. Pobjednički rudar nagrađen je Bitcoinima. Bitcoin nagrade se prepolovljuju svakih 210.000 blokova. Na primjer, nagrada za blok bila je 50 novih bitcoina u 2009. godini, a 11. svibnja 2020. kad se dogodilo treće prepolovljenje nagrada za svaki blok smanjena je na 6.25 bitcoina. Četvrto prepolovljenje dogodilo se u travnju 2024. i smanjilo je nagradu na 3.125 Bitcoina. Sljedeće prepolovljavanje trebalo bi se dogoditi sredinom 2028. i smanjiti nagradu na 1.5625 BTC.

Do 2140. godine, nakon 32. prepolovljenja, nagrada za rudarenje Bitcoina smanjit će se na nulu, dosegnuvši ukupnu ponudu od 21 milijun BTC-a. Tada će se rudari oslanjati isključivo na naknade za transakcije kako bi pokrili svoje troškove.

Svako prepolovljenje smanjuje količinu novih BTC-a, što povijesno dovodi do porasta cijene zbog smanjene ponude i povećane potražnje. Iako će se učinak budućih prepolovljenja možda smanjivati zbog sve manjih količina nove ponude, do sada su ta prepolovljenja bila ključni pokretači triju glavnih tržišnih ciklusa Bitcoina.

It was a dark and stormy night. It had to be: Weather had been fired. If they were working for him he would have fired them, but that is just embarrassed arrogance talking. He remembers standing in the middle of his office, his trashed office. It looked like a hurricane had hit it, or vagrants had been living in it for years, nothing of value was left intact. Monitors were shattered on the floor, couches were covered in debris. There was evidence of food and magazine pages in every gaze space. His supervisor, his name escaped him, was grey with anger. “Explain this!” he had shouted with a tremble, but he couldn’t. Every time he tried to think of the events of the day he met a dazzling white blankness.

He was escorted, handcuffed, to a room by two security guards with his supervisor trailing them. Weather felt humiliated and frustrated, but he didn’t know why. He sat, shivering slightly, in a low-lit conference room he had never seen before. Actually, he doesn’t remember any windows or any specific light source, just a haze of shadows. The big boss is sitting opposite him, looking haggard and white as a sun-bleached shell. His supervisor was sitting on his right looking equally haggard and even depressed. They appeared genuine and he knew it was bad news for him.

“You’ve embarrassed this company! There is even a chance you have ruined us all and you have the audacity to sit there and pretend that you can’t remember a thing!”

He knew there was no point in arguing, he had no ideas with which to make up any argument. He sat staring into space.

“At least, give us a story. Tell us how bored you were and tried to create your own weather system by running around the room swinging the fan around like a sugar mad teenager!”

He couldn’t even clear his throat. He couldn’t lift his eyes to meet theirs. He knew his career was over and they were fearful all their ideals had crashed irreparably. He stared into space at the globe standing in the middle of the table. The more he stared at it the more he realized that it seemed to have an atmosphere around it. There were clouds covering patches of the earth. He didn’t dare bring their attention to it. The only memories he could dredge up seemed like dreams, and they’re hardly constitute a defence.

He looked up at their faces finally, surprised to see more alarm than anger, like they were actually afraid of him. They both stood up suddenly, wanting to get out the room as quickly as possible.

“You have brought Global Sky Incorporated into disrepute. You’ve embarrassed us. You have possibly ruined hundreds of careers here! We never want to see you again! You are never to come within a hundred metres of this building. You can never use your research ever again, it never happened. Everything you have ever written will be classified and restricted until you are dead!” The big boss was shaking wild, Weather was grateful for the security guards that hurled him out of his chair and marched him out of the building.

The afternoon sky had been a deathly grey. It had occurred to him but now he was a little shocked at how much control they had over the weather, maybe it was a good thing that he had been fired, but probably a bad thing as they would certainly make worse mistakes than him, whatever he might have done. He was confused, not sure if he been fired for trashing his office or for state of the weather. About the weird weather he has no idea, all he can remember is a dazzling blank whiteness, and that is hardly a memory.

He couldn’t face going directly home, jumped on public transport travelling on tracks laid down on old unused highways and headed for the city beach, or what passed for a beach. He sat on a concrete bench gazing across the grey sand at the shimmering waves. They weren’t shimmering because of the sparkling sunlight, but the contaminates in the water. But still it was tranquil enough. He tried to think about his day, but couldn’t get past the white blankness, everything else before that was like a postcard from someone else’s holiday, and they looked like movies he might have seen. He has a framed vision of himself in his office with office supplies flying around him without touching him. Clearly, as they weren’t touching him, it had nothing to do with his behaviour. He is a victim here. It wasn’t his fault, the world was changing and the powers that be wanted more control. It seems like Global Weather Incorporated (GWI) lost control of their equipment and need a fall guy, they didn’t need him anymore. Squeezed his brain for the algorithms, then threw him onto the streets. He was nothing without his research, it’s all he had done his entire life. He would have to pursue it, but that would as useful as talking to a brick wall, the world was less transparent; government, science and advertising companies had a law of their own and a police force to uphold them.

He believed in good and the unveiling of truth. He had a romantic connection to the idea that truth grew in people’s hearts that everyone wanted the best for everyone else, no matter what skin colour, car colour they had, or star sign they were born under. Everybody wanted peace, a roof over their heads and food in their bellies; and wanted these things for their neighbours too. If only his neighbours had the same beliefs.

It was late afternoon now. He could tell by the slight luminosity of the grey clouds near the horizon, close to a cloudless gap, a slit above the horizon through which the sun could bid its final farewell to the day. He was in no mood for a sunset minute. He picked his bum off the bench, dusted it off and began his journey home, not wanting to be left in the dark in the city, opportune prey for corrupt cops. Everyone was coming out of the offices, beginning the big commute home. Car pools had reshaped their cars to fit more people in, and many climbed on to the reinvented trams, sitting if they were lucky, holding onto ceiling straps if they were unlucky like him. Couples sat together staring into each other’s eyes, friends joked and discussed their office politics. He hated the commute back and forth from work, it made him feel alone, desperate and unwanted. There had been no office politics for him, it was just him and his mostly silent supervisor.

The sky was struck red, a wound inflicted on the sky, it bleed for a minute then all went dark. Reality shuddered as it returned to him, this would be his last commute along this route. He was without a job; his recently regained self-esteem was destroyed. At the end of university he had wondered if he had a career anywhere, if his self-inflicted social isolation had been worth it and GWI had lifted him out of academic gutter and placed him on a pedestal. And now he was turfed out like a partly cloudy day from a child’s memory, flicked off like an ant off a picnic blanket.

Litter was being chased up and down the aisle, wrapping around legs and trying to hide from the wind amongst commuters’ bags. He didn’t notice that the commuters were becoming concerned about the weather, heads turned to look outside where the clouds were blacker than night. Wind has beating on windows, knocking on doors trying to escape from itself. Loose objects were starting to drift.

“Puck, I’m so stupid!” Weather lamented aloud as a flash of lightning brightened the dusk for a second. He should have protected his research, patented it in his own name. Stupidly, he had thought he would be with GWI for the rest of his life. He had given his life over to GWI and they had thrown it away for an office in disarray. It might have looked like an unnatural disaster, but they could have at least let him evaluate their equipment to check for systems failure. Why he hadn’t opened his mouth and flung accusations back at them? Probably because they had looked angrier than he could possibly have gotten faced with a memory of shimmering blankness.

The weather was surreal, he casually noted it as something GWI would have to correct, something existing outside his present unemployed reality, their problem. His cellphone’s classic “Thunderstuck” ringtone charged the air.

“What’s happening with the weather, dude? I thought I read in the paper that it was supposed to be sunny skies and calm seas. I wanted to go for an evening dive at Devil’s.”

“I’ve no idea, I’ve been fired,” he managed to say calmly before he hung up.

“It’s not my responsibility,” he thought to himself and promptly switched his phone off. He had given his private cellphone number to a few select acquaintances he had tried to impress when he had just got his ‘prestigious’ job. He thought he might finally be able to get his social life out of his house by sharing information with people he had met in supermarkets, recognizing their faces from university. They were jocks obsessed about the weather for their hedonistic lifestyles and they had never invited him out, only phoning to find out about the weather.

He jumped off at his usual stop and leaned into the wind watching his feet moving past one another, his mind seething at the injustice of not having a fair trial where they showed him evidence of him been directly involved in the trashing of his office. He could only remember standing in the middle of it and his office revolving around him, but that was only a flash, there is nothing before that except the facts. Him working on algorithms of weather activation, them tinkering with the clouds. They were practically at the end of their testing, their final live weather event before taking on the whole world’s weather, he knows that, but everyday was still just the same as every other day, him at the computer, them throwing lightning bolts. “Puck! I should’ve challenged them,” he shouted into the howling wind at GSI with all the frustration of his past mistakes. But his voice was lost into the atmosphere.

Crabtree's Framework for Evaluating Human-Centered Research

Picture this: You've spent three weeks conducting qualitative research for a finance app redesign. You carefully recruited 12 participants, conducted in-depth interviews, and identified patterns around financial anxiety and decision paralysis. You're excited to present your findings when the inevitable happens:

"But are these results statistically significant?"

"Just 12 people? How can we make decisions that affect thousands of users based on conversations with just 12 people?"

As UX professionals, we regularly face stakeholders who evaluate our qualitative research using criteria designed for quantitative methods... This misalignment undermines the unique value qualitative research brings to product development.

Introduction

Me and Fishcake have been working on infrastructure for Noswhere and Nostr.build. Part of this involves processing a large amount of Nostr events for features such as search, analytics, and feeds.

I have been recently developing nosdex v3, a newer version of the Noswhere scraper that is designed for maximum performance and fault tolerance using FoundationDB (FDB).

Fishcake has been working on a processing system for Nostr events to use with NB, based off of Cloudflare (CF) Pipelines, which is a relatively new beta product. This evening, we put it all to the test.

First preparations

We set up a new CF Pipelines endpoint, and I implemented a basic importer that took data from the nosdex database. This was quite slow, as it did HTTP requests synchronously, but worked as a good smoke test.

Asynchronous indexing

I implemented a high-contention queue system designed for highly parallel indexing operations, built using FDB, that supports: - Fully customizable batch sizes - Per-index queues - Hundreds of parallel consumers - Automatic retry logic using lease expiration

When the scraper first gets an event, it will process it and eventually write it to the blob store and FDB. Each new event is appended to the event log.

On the indexing side, a Queuer will read the event log, and batch events (usually 2K-5K events) into one work job. This work job contains: - A range in the log to index - Which target this job is intended for - The size of the job and some other metadata

Each job has an associated leasing state, which is used to handle retries and prioritization, and ensure no duplication of work.

Several Workers monitor the index queue (up to 128) and wait for new jobs that are available to lease.

Once a suitable job is found, the worker acquires a lease on the job and reads the relevant events from FDB and the blob store.

Depending on the indexing type, the job will be processed in one of a number of ways, and then marked as completed or returned for retries.

In this case, the event is also forwarded to CF Pipelines.

Trying it out

The first attempt did not go well. I found a bug in the high-contention indexer that led to frequent transaction conflicts. This was easily solved by correcting an incorrectly set parameter.

We also found there were other issues in the indexer, such as an insufficient amount of threads, and a suspicious decrease in the speed of the Queuer during processing of queued jobs.

Along with fixing these issues, I also implemented other optimizations, such as deprioritizing Worker DB accesses, and increasing the batch size.

To fix the degraded Queuer performance, I ran the backfill job by itself, and then started indexing after it had completed.

Bottlenecks, bottlenecks everywhere

After implementing these fixes, there was an interesting problem: The DB couldn't go over 80K reads per second. I had encountered this limit during load testing for the scraper and other FDB benchmarks.

As I suspected, this was a client thread limitation, as one thread seemed to be using high amounts of CPU. To overcome this, I created a new client instance for each Worker.

After investigating, I discovered that the Go FoundationDB client cached the database connection. This meant all attempts to create separate DB connections ended up being useless.

Using OpenWithConnectionString partially resolved this issue. (This also had benefits for service-discovery based connection configuration.)

To be able to fully support multi-threading, I needed to enabled the FDB multi-client feature. Enabling it also allowed easier upgrades across DB versions, as FDB clients are incompatible across versions:

FDB_NETWORK_OPTION_EXTERNAL_CLIENT_LIBRARY="/lib/libfdb_c.so" FDB_NETWORK_OPTION_CLIENT_THREADS_PER_VERSION="16"

Breaking the 100K/s reads barrier

After implementing support for the multi-threaded client, we were able to get over 100K reads per second.

You may notice after the restart (gap) the performance dropped. This was caused by several bugs: 1. When creating the CF Pipelines endpoint, we did not specify a region. The automatically selected region was far away from the server. 2. The amount of shards were not sufficient, so we increased them. 3. The client overloaded a few HTTP/2 connections with too many requests.

I implemented a feature to assign each Worker its own HTTP client, fixing the 3rd issue. We also moved the entire storage region to West Europe to be closer to the servers.

After these changes, we were able to easily push over 200K reads/s, mostly limited by missing optimizations:

It's shards all the way down

While testing, we also noticed another issue: At certain times, a pipeline would get overloaded, stalling requests for seconds at a time. This prevented all forward progress on the Workers.

We solved this by having multiple pipelines: A primary pipeline meant to be for standard load, with moderate batching duration and less shards, and high-throughput pipelines with more shards.

Each Worker is assigned a pipeline on startup, and if one pipeline stalls, other workers can continue making progress and saturate the DB.

The stress test

After making sure everything was ready for the import, we cleared all data, and started the import.

The entire import lasted 20 minutes between 01:44 UTC and 02:04 UTC, reaching a peak of: - 0.25M requests per second - 0.6M keys read per second - 140MB/s reads from DB - 2Gbps of network throughput

FoundationDB ran smoothly during this test, with: - Read times under 2ms - Zero conflicting transactions - No overloaded servers

CF Pipelines held up well, delivering batches to R2 without any issues, while reaching its maximum possible throughput.

Finishing notes

Me and Fishcake have been building infrastructure around scaling Nostr, from media, to relays, to content indexing. We consistently work on improving scalability, resiliency and stability, even outside these posts.

Many things, including what you see here, are already a part of Nostr.build, Noswhere and NFDB, and many other changes are being implemented every day.

If you like what you are seeing, and want to integrate it, get in touch. :)

If you want to support our work, you can zap this post, or register for nostr.land and nostr.build today.

Godišnjica objavljivanja revolucionarnog dokumenta nije samo podsjetnik na nastanak Bitcoina, već i na značajnu promjenu koju je donio u načinu na koji razmišljamo o novcu i ekonomskom suverenitetu. Njegov značaj premašuje ideju o zaradi na promjeni njegove vrijednosti, jer otvara vrata širem razumijevanju digitalne imovine i decentralizovanih finansija koje inspirišu moderno bankarstvo i platne sisteme da se razvijaju u drugačijem smjeru, povećavajući svijest o sigurnosti i dostupnosti.

Šesnaest je godina od objavljivanja dokumenta naslovljenog kao "Bitcoin: A Peer-to-Peer Electronic Cash System", poznatog i kao „biijeli papir“ (white paper) u kojem su izloženi koncept i svrha novog sistema digitalne valute – sistema koji bi funkcionisao nezavisno od bilo koje vlade ili finansijske institucije. Bijeli papir, kojeg je 31. oktobra 2008. objavio pojedinac ili tim ljudi pod imenom Satoši Nakamoto ponudio je smjelo rješenje za sve veći problem – kontrolu valute centralnih banaka i sve veće poteškoće u prenošenju vrijednosti preko interneta bez posrednika. Ovaj trenutak označio je nastanak Bitcoina, revolucionarne digitalne valute i prve kriptovalute na svijetu koja je kasnije lansirana 3. januara 2009. godine.

Bitcoin je nastao u vrijeme finansijske krize 2008. godine, u periodu kada je povjerenje u tradicionalne finansijske sisteme bilo na izuzetno niskom nivou. Ljudi su počeli da se pitaju da li postoji način za upravljanje novcem koji ne zavisi od banaka, koje, kao što su tadašnji događaji pokazali, mogu propasti ili djelovati na načine koji nijesu u najboljem interesu javnosti. Nakamotova inovacija, Bitcoin, bila je zamišljena kao sistem u kojem korisnici mogu direktno slati i primati novac, zaobilazeći potrebu za bankama. U tom procesu, Nakamoto je svijetu predstavio novu tehnologiju kojoj je kasnije američki naučnik i programer Harold Fini dao naziv blockchain – decentralizovan i otporan na manipulacije način za evidentiranje transakcija.

Šta je Bitcoin?

Bitcoin je vrsta digitalne valute koja omogućava ljudima da direktno jedni drugima šalju i primaju vrijednost putem interneta. Za razliku od tradicionalnih valuta, kao što je euro ili dolar, koje kontrolišu vlade i banke, Bitcoin funkcioniše bez centralne vlasti. To znači da nema nikoga ko je zadužen za njega i nema banke koja odlučuje kako se može koristiti. Umjesto toga, Bitcoin se oslanja na veliku mrežu računara širom svijeta koja ga održava i bilježi njegove transakcije. Ova mreža je poznata kao „Bitcoin mreža“.

Kako Bitcoin funkcioniše?

U suštini, Bitcoin funkcioniše kao „decentralizovana digitalna valuta“. Kada kažemo decentralizovana, mislimo da nijedna osoba, kompanija ili vlada ne kontroliše Bitcoin. Umjesto toga, svaka transakcija se bilježi na zajedničkoj knjizi, nazvanoj blockchain, koju održava mreža računara širom svijeta. Svaki put kada neko pošalje ili primi Bitcoin, transakcija se grupiše sa drugima i dodaje u ovaj lanac blokova. Budući da je ovaj lanac kopiran i dijeljen među brojnim računarima, gotovo je neizvodljivo izmijeniti ili hakovati ga, čime se osigurava da Bitcoin transakcije budu bezbjedne i pouzdane.

Još jedan interesantan aspekt je da Bitcoin ima ograničenu ponudu. Kreiran je samo 21 milion bitcoina, što ga čini rijetkom imovinom i sprečava inflaciju na način na koji to može biti slučaj sa tradicionalnim valutama koje se „doštampavaju“. Bitcoin transakcije su omogućene kroz skup kriptografskih pravila, koja ljudima omogućavaju da potvrde svaku transakciju kao legitimnu bez potrebe da vjeruju trećoj strani. Ovaj skup pravila je poznat kao kriptografija, zbog čega se Bitcoin naziva kriptovalutom – prvom koja je ikada stvorena i jedinom koja u potpunosti ima sve karakteristike onoga što je istinska ideja i svrha postojanja kriptovaluta.

Razumijevanje finansijske revolucije Bitcoina

Bitcoin, predstavljen 2008. godine, privukao je globalnu pažnju kao decentralizovana digitalna valuta koja funkcioniše nezavisno od banaka i vlada, ali pored svoje peer-to-peer arhitekture i decentralizovane infrastrukture, on ima jedinstvenu finansijsku karakteristiku – inherentno je deflatoran. Za razliku od fiat valuta poput dolara ili eura, koje centralne banke mogu štampati kada procijene da je to potrebno, ponuda Bitcoina je ograničena, fiksirana i ne povećava se. Ova deflatorna osobina navela je mnoge da ga vide kao revolucionarni finansijski instrument, „digitalno zlato“ koje bi moglo da preoblikuje koncepte vrijednosti, očuvanja bogatstva i monetarne politike.

Fiksna ponuda – limit od 21 miliona

Najkarakterističnija odlika Bitcoina je njegova ograničena ponuda. Kada je Satoši Nakamoto kreirao Bitcoin, postavio je ograničenje na ukupan broj bitcoina koji će ikada postojati – 21 milion. Ovo ograničenje se oštro razlikuje od tradicionalnih fiat valuta, gdje centralne banke mogu povećavati ponudu novca štampanjem dodatne količine. Postavljanjem ovog ograničenja, Nakamoto je osigurao da Bitcoin postane sve rjeđi vremenom, karakteristika koja je dizajnirana za očuvanje vrijednosti kako potražnja raste.

U tradicionalnim finansijama, valute mogu izgubiti vrijednost kada se previše štampaju, što se može vidjeti u slučajevima inflacije. Bitcoinov dizajn, međutim, znači da, kada se posljednji Bitcoin izrudari (što se predviđa oko 2140. godine), novi novčići neće ulaziti u cirkulaciju, što ga efektivno čini prvom deflatornom valutom u velikom obimu.

Mehanizam smanjenje ponude tokom vremena

Oskudica Bitcoina dodatno se pojačava procesom nazvanim „halving“ (prepolovljenje), koji smanjuje stopu stvaranja novih bitcoina. Približno svake četiri godine nagrada koju „rudari“ dobijaju za dodavanje novih blokova u blockchain se prepolovi. Ovaj mehanizam smanjuje mogućnost inflacije Bitcoina tokom vremena, stvarajući predvidivo, postepeno smanjenje ponude.

U početku su rudari dobijali 50 bitcoina po bloku. Nakon prvog halvinga 2012. godine, nagrada je pala na 25, a do 2020. smanjila se na 6,25 bitcoina po bloku. Ovaj proces halvinga će se nastaviti sve do približno 2140. godine, kada će svih 21 milion bitcoina biti u cirkulaciji, a rudari će biti podstaknuti isključivo transakcionim naknadama, umjesto novim novčićima. Halving ima dva osnovna učinka – usporava rast ponude Bitcoina i stvara predvidivu oskudicu koja može podstaći tražnju, jer učesnici na tržištu znaju da će sa svakim ciklusom biti sve manje dostupnih bitcoina.

Zašto je Bitcoin važan?

Većina tradicionalnih valuta je inflaciona po dizajnu. Centralne banke teže kontrolisanoj stopi inflacije, često oko 2%, kako bi podstakle ekonomski rast, ohrabrile potrošnju i pružile fleksibilnost u odgovoru na ekonomske krize. Međutim, ova inflacija može potkopati kupovnu moć fiat valuta vremenom, što je zabrinjavajuće tokom perioda prekomjernog štampanja novca, kao što su mjere i programi kvantitativnog popuštanja viđene posljednjih godina.

Bitcoinov deflatorni dizajn je revolucionaran u ovom kontekstu jer nudi potencijalnu zaštitu od inflacije. Sa fiksnom ponudom, Bitcoin može da dobija na vrijednosti tokom vremena, posebno ako potražnja raste jer postaje rjeđi. Za mnoge, deflatorni model Bitcoina čini ga privlačnim sredstvom za očuvanje bogatstva na način koji tradicionalne valute i imovina ne mogu da ponude.

Pored toga, ovaj model izazvao je promjenu čitave filozofije u načinu na koji ljudi razmišljaju o novcu, investiranju i štednji. Dok tradicionalne finansije podstiču potrošnju i investicije kroz inflaciju, deflatorna priroda Bitcoina može podstaći štednju, jer bi njegova vrijednost mogla da raste u budućnosti. Ovaj kvalitet „čuvara vrijednosti“ naveo je mnoge da Bitcoinu daju naziv „digitalno zlato“.

Ekonomija oskudice – ono što Bitcoinu daje vrijednost

U ekonomiji, oskudica obično povećava vrijednost, jer tražnja za ograničenim resursom može povećati njegovu cijenu. Zlato je, na primjer, dugo bilo čuvar vrijednosti zbog svoje oskudice i poteškoća u vađenju. Bitcoin odražava ovaj koncept u digitalnom svijetu. Inherentno je rijedak zbog ograničenja od 21 milion, i, kao zlato, zahtijeva trud (kroz digitalno rudarenje) da bi ušao u cirkulaciju.

Pored toga, oskudica Bitcoina postaje sve izraženija kako raste interesovanje institucija i pojedinaca. Mnogi investitori privučeni su Bitcoinom kao dugoročnom imovinom upravo zbog ove fiksne ponude, oslanjajući se na to da će rastuća tražnja naspram ograničene ponude povećati njegovu vrijednost tokom vremena. Ova privlačnost je pojačana u regionima sa brzom inflacijom ili ekonomskom nestabilnošću, gdje rizik od devalvacije čini Bitcoin privlačnom alternativom za očuvanje bogatstva.

Bitcoin kao globalni čuvar vrijednosti

Osim što je sredstvo razmjene, deflatorna priroda Bitcoina pozicionira ga kao potencijalni globalni čuvar vrijednosti. Zlato je istorijski imalo ovu ulogu, jer su ga koristili pojedinci, institucije i vlade kao zaštitu od ekonomske nestabilnosti i inflacije. Bitcoin postaje moderni pandan tome, posebno privlačan mlađim generacijama i investitorima sklonim tehnologiji, koji ga vide kao superiornu alternativu.

Deflatorni dizajn takođe omogućava Bitcoinu da prelazi međunarodne granice i nadilazi lokalne ekonomske uslove. U zemljama koje prolaze kroz valutne krize, Bitcoin nudi alternativu koja je bez granica i nezavisna od politika centralne banke. Ova sposobnost da djeluje kao čuvar vrijednosti posebno je značajna na tržištima i ekonomijama u razvoju, gdje je valutna nestabilnost učestalija.

Može li oskudica Bitcoina predstavljati rizik?

Iako deflatorni model Bitcoina ima svoje prednosti, nije bez kritika. Jedna od zabrinutosti je da ekstremna deflacija može obeshrabriti potrošnju. U sistemu gdje vrijednost valute raste tokom vremena, ljudi mogu preferirati štednju umjesto potrošnje ili investiranja, što može dovesti do smanjenja ekonomske aktivnosti. Ekonomisti brinu da bi, ako Bitcoin postane široko prihvaćena valuta, njegova deflatorna priroda mogla ugroziti ekonomski rast podsticanjem „gomilanja“ umesto cirkulacije.

Još jedna kritika se odnosi na fiksnu ponudu Bitcoina u ekonomiji koja stalno raste. Tradicionalne valute su inflatorne kako bi pratile rast populacije, ekonomije i produktivnosti. Sa ograničenom ponudom, Bitcoin ne može da raste u skladu sa ekonomskim razvojem, što bi u teoriji moglo izazvati probleme sa likvidnošću u ekonomiji zasnovanoj na Bitcoinu. Ipak, kako ideja nije da Bitcoin bude jedino sredstvo plaćanja, strah od takvog scenarija je neutemeljen, budući da ekosistem u kojem funkcioniše koegzistira sa nizom drugih platnih sistemna koji su na raspolaganju širom svijeta.

Eliminiše problem dvostrukog trošenja

U svijetu novca postoji veliki problem koji se naziva „dvostruko trošenje“. Zamislite da možete potrošiti iste eure dvaput – platite jedan proizvod ili uslugu, a zatim, nekako, uspijete da ga ponovo potrošite na nešto drugo. U fizičkom svijetu ovo nije problem, ali u računovodstvenom jeste. Ako kao fizičku valutu u gotovini platite nešto, ta količina novca odlazi iz vašeg novčanika, ali u bankovnim transakcijama stvari funkcionišu drugačije.

Da bi se osiguralo da Bitcoin ne može biti kopiran ili potrošen dvaput, koristi se tehnologija zvana blockchain. Nakamotov Bijeli papir još nije pomenuo taj izraz, jer mu je naziv dat nekoliko dana kasnije, no umjesto toga, opisao je koncept „lanca blokova“, postavljajući sistem za evidentiranje transakcija u blokovima koji su međusobno povezani. Ovaj koncept je kasnije postao poznat kao blockchain, termin koji je nastao nakon izdavanja Bitcoina dok su ljudi pokušavali da imenuju osnovnu tehnologiju. Fokus Bijelog papira bio je na tome kako Bitcoin može bezbjedno pratiti i potvrđivati transakcije, koristeći ovaj povezani lanac blokova kao neku vrstu digitalne knjige.

Pristup iz Bijelog papira uveo je revolucionarnu ideju – zajedničku, otpornu na manipulacije evidenciju koja se nije oslanjala na centralnu vlast za ažuriranje ili verifikaciju. Ovaj sistem povezanih blokova (ono što sada nazivamo blockchain) postao je osnova Bitcoina i, kasnije, bezbroj drugih primjena u finansijama, tehnologiji i brojnim drugim oblastima.

Ova baza je poput ogromne digitalne knjige, ili evidencije, u kojoj je svaka Bitcoin transakcija (prenosa novca od jednog do drugog korisnika) zabilježena. Ono što ovu digitalnu evidenciju čini posebnom jeste to što nije smještena na jednom mjestu, niti je pod kontrolom jedne osobe ili institucije – ona je u potpunosti decentralizovana, što znači da se kopije ove knjige čuvaju na hiljadama računara širom svijeta, a svi oni moraju da se saglase oko toga koje transakcije su validne.

Svaki put kada neko pošalje Bitcoin drugoj osobi, ova transakcija se dodaje u blockchain. Da bi se dodala, grupa računara (nazvana „rudari“) mora da verifikuje da je ova transakcija stvarna, što znači da Bitcoin koji se troši već nije korišćen drugdje. Ovi rudari rade zajedno, koristeći složene matematičke operacije, kako bi potvrdili transakcije. Kada se verifikuje, transakcija se dodaje u blockchain, a cijela mreža se ažurira kako bi prepoznala ovu transakciju kao legitimnu. Ovaj proces osigurava da nijedan Bitcoin ne može biti potrošen dvaput, rješavajući problem dvostrukog trošenja.

Peer-to-Peer transakcije bez posrednika

Još jedan veliki razlog zašto je Bitcoin važan je taj što omogućava ljudima da šalju novac direktno jedni drugima bez potrebe za posrednikom. Recimo da želite da pošaljete novac prijatelju koji živi u drugoj zemlji. Obično biste otišli u svoju banku, koja bi se povezala s drugom bankom u toj zemlji, što može trajati danima i uključivati različite naknade.

Međutim, Bitcoin je omogućio da se direktno pošalju sredstva, bez obzira na to gdje se nalazite u svijetu. Pošto je u pitanju peer-to-peer (P2P) način razmjene, nema potrebe za posrednikom da upravlja transakcijom. To može učiniti transakcije bržim i ponekad jeftinijim, posebno kada se sredstva šalju međunarodno. Ova P2P struktura je jedan od glavnih razloga zbog kojih ljudi se na ovaj oblik imovine gleda kao na alternativu složenim transakcijama, posebno važnim za društva i sredine u kojima je dostupnost finansijskih usluga niska.

Transparentnost i sigurnost

U svijetu tradicionalnog bankarstva, ljudi se oslanjaju na banke koje drže novac sigurnim i omogućavaju da transakcije budu poštene i sigurne. Međutim, s Bitcoinom, povjerenje nije smešteno u centralnu banku ili kompaniju, već u samu Bitcoin mrežu, koju održavaju svi računari koji prate blockchain. Pošto je blockchain javan i može ga provjeriti bilo ko, on je veoma transparentan. Svaka transakcija koja je ikada obavljena Bitcoinom zabilježena je u ovoj javnoj knjizi, tako da ako neko pokuša da prevari sistem, to bi bilo očigledno svima.

Transparentnost Bitcoina takođe ga čini veoma sigurnim. Pošto svi u mreži imaju kopiju blockchaina, bilo bi gotovo nemoguće da jedna osoba ili čak grupa ljudi izmijeni ili preuzme kontrolu nad njim. Da biste promijenili blockchain, morali biste kontrolisati više od polovine svih računara širom svijeta u Bitcoin mreži, što je izuzetno teško. Ovaj nivo sigurnosti, u kombinaciji s transparentnošću, pomaže ljudima da se osjećaju sigurno koristeći Bitcoin.

Značaj za razvoj finansija

Tokom godina, Bitcoin je postao više od eksperimenta u digitalnom novcu. Inspirisao je hiljade drugih kreatora latnih rješenja i pokrenuo važne razgovore o budućnosti novca, povjerenja i tehnologije. Kako sve više ljudi počinje da preispituje kako tradicionalne banke funkcionišu i traži nove načine za upravljanje svojim finansijama, Bitcoin ostaje snažna opcija ne samo u smislu alternative, već mogućnosti povezivanja njegove funkcionalnosti sa onim što već postoji u finansijskoj tehnologiji. Njegov značaj je u tome što predstavlja potpuno novi način razmišljanja o novcu i njegovom korišćenju i što rješava neke od ključnih problema koji su karakteristični finansijske sisteme.

Ideja decentralizacije

U mnogim sistemima koje danas koristimo postoji centralna vlast – banka, vlada ili kompanija – koja ima kontrolu i koja donosi pravila, odlučuje ko ima pristup i odobrava aktivnosti, što je prilično spor i skup proces u cjelini. Koncept Bitcoina je drugačiji jer je decentralizovan, a to znači da ne postoji jedna osoba, banka ili organizacija koja donosi odluke, već je to prepušteno mreži koju čine milioni korisničkih uređaja na mreži koji održavaju sistem u funkciji.

Pored toga, decentralizacija onemogućava cenzurisanje, jer niko ne može da interveniše i blokira nečiji pristup ili transakcije. To čini sistem demokratskijim, omogućavajući ljudima širom svijeta da se pridruže bez traženja dozvole.

Kriptografski dokazi – vjerovanje u matematiku, a ne u ljude

Kada nešto kupite koristeći Bitcoin, ne morate se oslanjati na posrednika da verifikuje vašu transakciju. Umjesto toga, Bitcoin koristi nešto što se naziva „kriptografskim dokazom. Kriptografski dokazi su poput digitalnog ključa i brave koji čuvaju informacije sigurnima, jer se oslanjaju na složenu matematiku koja osigurava da se samo validne transakcije dodaju u blockchain, onemogućavajući falsifikovanje ili prevaru.

Kriptografski dokazi funkcionišu tako što kreiraju heš (hash) – dug i jedinstven broj, za svaki blok transakcija. Svaki heš je povezan s prethodnim, što pomaže u obezbjeđivanju cijelog lanca. Matematika iza ovog procesa je toliko složena da bi zahtijevala ogromnu računarsku moć kada bi i pokušala da je razbije. Koristeći kriptografske dokaze, Bitcoin ne zahtijeva povjerenje u ljude, već se umjesto toga, oslanja na neprobojne matematičke algoritme da osigura svaku transakciju.

Proof of Work – digitalna zagonetka koja štiti Bitcoin

Bitcoinova mreža je osigurana procesom koji se naziva Proof of Work (dokaz o radu), koji je najjednostavnije razumjeti ako ga zamislite kao izazovnu zagonetku koju računari, poznati kao „rudari“, moraju da riješe da bi dodali novi blok u blockchain. Prvi računar koji riješi zagonetku dobija priliku da doda blok i dobija nagradu u bitcoinima. Ova zagonetka je izuzetno složena i zahtijeva od rudara da koristi veliku količinu mnogo računarske snage, što je skupo u smislu vremena i energije.

U tom smislu Proof of Work čuva mrežu sigurnom, jer kad bi neko pokušao da prevari sistem ponovnim pisanjem blockchaina, morao ponovo da uradi svako izračunavanja dokaza o radu za svaki blok koji želi da izmijeni, što je praktično nemoguće. Na ovaj način Bitcoin kreira mrežni sistem u kojem je prevara previše skupa i previše složena da bi se bilo kome isplatila.

Šesnaest godina kasnije...

Bitcoin je za ovo vrijeme postao mnogo više od digitalne valute – on je simbol finansijske nezavisnosti i pokretačka snaga nove finansijske tehnologije i ekonomskih koncepata. Pokrenuo je diskusije o budućnosti novca, a inspirisao je brojne pružaoce platnih usluga, uključujući brojne banke širom svijeta i FinTech kompanije, da unapređuju poslovni model.

Zbog količine koja je u opticaju njegova upotreba kao valute ostaje ograničena u poređenju s tradicionalnim novcem, dok njegova cijena nastavlja da fluktuira u zavisnosti od tržišnih okolnosti. U tom smislu uticaj Bitcoina na finansije, tehnologiju i društvo u cjelini već je dubok, navodeći promišljenije i kreativnije istraživanje kako se vrednostima može upravljati i razmenjivati u savremenom svijetu, podstičući značaj decentralizacije i svijest o zaštiti podataka.

Iako često predstavljan kao sredstvo za „brzo bogaćenje“ ili sresdstvo za obavljanje anonimnih transakcija, motivi za njegovo kreiranje, kao i njegova uloga u finansijskom i tehnološkom svijetu potpuno se razlikuju od toga. Bitcoin je prva, najstarija, najvrednija i – u najširem smislu – po svim parametrima jedina prava, potpuno decenztralizovana kriptovaluta koja je transformisala način na koji razmišljamo o novcu, povjerenju i bezbednosti u digitalnoj eri.

Not picking up new version. Perhaps due to default timestamp: root@OpenWrt:~# cat /etc/tollgate/install.json | jq { "package_path": "false", "ip_address_randomized": "false", "install_time": 0, "download_time": 0, "release_channel": "stable", "ensure_default_timestamp": 1746781946 }

Re-ran the workflow to generate the event again with a newer timestamp: { "id": "d30f92cdacf453bede2bd36d62231fc40b226cc183239f5daf724829d81bd192", "pubkey": "c0757f43081aa96a8733b58fb7f745d8c784ecdfc02477a1b7b99e35416fff0b", "created_at": 1746782339, "kind": 1063, "content": "TollGate Module Package: basic for gl-mt3000", "tags": [ [ "url", "https://blossom.swissdash.site/700bfb2e1788d8f42c89492562e8503979761ef7d07b7a412f6d9334d7f24f6f.ipk" ], [ "m", "application/octet-stream" ], [ "x", "700bfb2e1788d8f42c89492562e8503979761ef7d07b7a412f6d9334d7f24f6f" ], [ "ox", "700bfb2e1788d8f42c89492562e8503979761ef7d07b7a412f6d9334d7f24f6f" ], [ "filename", "basic-gl-mt3000-aarch64_cortex-a53.ipk" ], [ "architecture", "aarch64_cortex-a53" ], [ "version", "v0.0.6" ], [ "release_channel", "stable" ] ] }

Unfortunately, we can't do much about it, because all the more relevant timestamps were deleted when the config file was deleted. At-least we have this default timestamp to fall back on. Considering this test successful..

You are wearing a helmet, but it's been on your head so long you no longer notice it.

The helmet interfaces with your mind via thought-emotion. It influences what you think about and how you feel.

You could remove the helmet at any time. But the thought-emotions keep you distracted, fearful and attached.

Occasionally you remember you are wearing it. Moments of clarity and detachment. You see the way your experience is colored by it. You know it is biased, untrue to reality. You seriously contemplate removing it.

But the moment passes.

Later, you remember contemplating your helmet’s removal, but you wonder what you will gain from it, whether it’s worth doing.

You are no longer having a moment of clarity, just a memory of the question that arose from it, but colored now by thought-emotions.

You decide even if you wanted to remove it, you would put it back on before long. After all, you have never kept it off before, why would you suddenly live without this interface now? The interface is what you know.

Maybe one day, when you are in a more secure place, when your ducks are more in a row, you will remove it. Not now, not in the midst of all this chaos, so many things to do, so much on your plate. You will leave it on for now. You will deal with this later.

But one day too late it dawns on you it is always ever now, and later means never. You have lived your entire life at the behest of the interface when all you had to do was remove it.

Što je bitcoin

Bitcoin je najstarija i najuspješnija kripto valuta na svijetu. Bitcoin svakodnevno puni naslovnice različitih medija diljem svijeta. Dok mnogi žele samo profitirati na njegovom uspjehu, drugi su ravnodušni ili čak skeptični. Nažalost malo je onih koji ga žele razumjeti. Zato svima vama koji ste sa čitanjem došli do ovog dijela želim čestitati! 😉

Danas je svatko u mogućnosti pridružiti se peer-to-peer mreži poznatoj kao Bitcoin. Mreža omogućava da bez pomoći treće strane (banka ili posrednik), sigurno sačuvate vrijednost tijekom vremena i da tu vrijednost bilo kome u bilo kojem trenutku možete poslati. Za razliku od današnjeg “normalnog” novca, bitcoin ima fiksan i transparentan raspored stvaranja i puštanja u optjecaj i taj raspored se ne može mijenjati po potrebi. Možemo ga smatrati cash-om interneta. Maksimalna količina bitcoina koji ikada može biti proizveden i pušten u optjecaj je 21 milijun (21.000.000).

Bitcoin sa velikim početnim B se koristi kada se o Bitcoinu priča u kontekstu mreže odnosno na razini protokola dok se bitcoin sa malim početnim b koristi kada se o bitcoinu priča kao o novcu ili valuti. Isto tako, u izvornom engleskom jeziku bitcoin nema množinu. Termin bitcoin se upotrebljava i kada govorimo o jednom bitcoinu i kada govorimo o više od jednog bitcoina. Nije ispravno reći „I will send you my bitcoins“ nego se kaže „I will send you my bitcoin“ i pri tome se misli na slanje više od jednog bitcoina. Kod nas ispravno je reći poslati ću ti bitcoin a ne poslati ću ti bitcoine. S obzirom da naš jezik ima svoje specifičnosti ispravno je reći 2 bitcoina a ne 2 bitcoin. Uglavnom, bitcoin nema množinu.

Bitcoin kao digitalna valuta potaknula je mnogobrojne rasprave o tehnologiji, novcu i ulaganju. Pojedinci bitcoin vide kao najobičnije sredstvo špekulacije i opisuju ga kao samo još jedan tržišni balon, dok drugi govore o tehnološkoj inovaciji, monetarnoj revoluciji ili čak sredstvu koja nas može izbaviti iz ralja postojećeg monetarnog sustava.

Razne zemlje, poput npr. Kine, bitcoin vide kao prijetnju te su mu objavile „rat“. Neke pak druge države svijeta i njihove vlade, države poput El Salvadora, priznale su bitcoin kao zakonito sredstvo plaćanja u nadi da će to potaknuti gospodarski rast.

Zašto je bitcoin važan

Sigurno ste se zapitali barem jednom u posljednjih nekoliko godina čemu sva ta pompa oko bitcoina? Gotovo je nemoguće danas otvoriti bilo koji internetski portal s vijestima ili neku aplikaciju društvenih mreža a da vas ne dočeka neki oblik informacije koji se tiče bitcoina ili ostalih kripto valuta. Jednostavno se možete zapitati zašto bi netko želio uopće želio posjedovati bitcoin? Odgovor na to pitanje je veoma jednostavan. Sve više i više ljudi shvaća da je u mogućnosti zaista posjedovati nešto što je digitalno, nešto što je nemoguće krivotvoriti i nešto što vam je nemoguće oduzeti ukoliko se sami toga dobrovoljno ne odreknete.

Bitcoin je otporan na cenzuru te omogućuje kriptografski sigurna prekogranična plaćanja. Budući da za provedbu takvih transakcija nije zadužena niti jedna osoba ili skupina (treća strana), to je prvi i jedini primjer prave deficitarne digitalne imovine. Stoga, na bitcoin ne može utjecati nijedna svjetska vlada.

Sudar svjetova

Tokom prošlosti kao sredstvo plaćanja korišteni plemeniti metali koji su kasnije zamijenjeni gotovinom u obliku kovanica i papirnih novčanica. Njihova prednost je ta da mogu biti spremljeni i trošeni neovisno o trećim stranama. Izreka “gotovina je sloboda” vrlo dobro ilustrira tu karakteristiku. Međutim, nedostatak plemenitih metala i gotovine je što ih je teško (gotovo nemoguće i potpuno nepraktično) koristiti u digitalnom internetskom prostoru. Nakon naglog rasta internetske trgovine, debitne i kreditne kartice su te koje su preuzele primat u plaćanjima u internetskom prostoru.

Danas kada velika većina ljudi koristi digitalni novac (koji se nalazi samo kao digitalni zapis na njihovim bankovnim računima) umjesto gotovine, rizici druge ugovorne strane s kojima se suočavaju rastu. Što to točno znači rizik druge strane? Ako npr. financijska institucija (banka) objavi da je postala nelikvidna, ušteđevina klijenata u tom slučaju može biti nepovratno izgubljena (bez obzira što države garantiraju da su depoziti do 100.000 eura u bankama osigurani i da će država u tako nekom slučaju namiriti taj dug svojim građanima). Ili, npr. kao što se tokom 2013. godine dogodilo na Cipru gdje je podizanje gotovine bilo ograničeno, uvedene su kapitalne kontrole i prisilno je izvlašten novac sa štednih računa građana. Jednom odlukom vlastodržaca u toj zemlji preko noći ljudi su ostali bez svoje ušteđevine. Ili, kao što je to slučaj danas u „razvijenim zapadnim demokracijama“ banka je jednostrano u mogućnosti svojem klijentu zabraniti da npr. pošalje novac svojoj obitelji na Kubu, Iran ili neku drugu zemlju. Ukoliko i uspiju svoj novac poslati kome žele, posrednička naknada (naknada treće strane za tu uslugu) će im zasigurno ostaviti gorak okus u ustima. Svi ovi i slični slučajevi predstavljaju rizik treće strane gdje su ljudi ostavljeni na milost ili nemilost sustava koji može dopustiti ali i bez objašnjenja zabraniti ovakve transakcije. Zbog sve više i više „nametnika“ poput banaka i parazitskih birokratskih institucija ljudi gube kontrolu nad svojim novcem.

S prelaskom s papirnog na digitalni novac koji je samo zabilješka na bankovnim računima, odrekli smo se kontrole nad vlastitim novcem. Ali do sada odnosno do izuma bitcoina, ovaj nedostatak je bila cijena koja se morala platiti ukoliko se željelo sudjelovati u „digitaliziranom životu“.

Bitcoin nudi rješenje za ovaj problem. Kao digitalni novac, idealan je za korištenje u digitalnom internetskom prostoru. U isto vrijeme, bitcoin se može čuvati kao digitalno vlasništvo bez potrebe oslanjanja na treće strane (banke) koja ih za nas može čuvati. Dakle, vlasnici bitcoina isti mogu čuvati u obliku privatnih ključeva. Ti privatni ključevi mogu se smatrati kao lozinke kojima se bitcoinu pristupa a koji se uvijek nalazi na blockchainu. Te privatne ključeve pojedinac može čuvati na način na koji god želi. Baš kao i gotovinu može ih spremiti ispod madraca ali puno mudrije bi bilo tih nekoliko riječi koje služe kao lozinka naučiti i zapamtiti.

Blockchain je banka. Banka koja je u vlasništvu svih nas a istovremeno nije u ničijem vlasništvu. Banka u koju nitko nema prvenstvo pristupa bez obzira koliko novca (bitcoina) u njoj ima, bez obzira odakle dolazi, koje je boje kože ili kojih je političkih ili vjerskih uvjerenja. Blockchain je banka koja nikome nikada neće niti može onemogućiti da svoj bitcoin pošalje kome god želi i kada god to želi. Blockchain nema bankarskog službenika kojemu se danas možda radi a možda i ne, koji može raditi greške u svom poslu i koji može biti potkupljen da nešto protupravno napravi. Blockchain je banka u kojoj smo svi apsolutno jednaki. Nema jednakih i jednakijih.

Savršeni trenutak

Bitcoin je nastao usred globalne financijske krize 2008/09. U prvom bloku Bitcoin blockchaina – koji se još naziva i blok nastanka (Genesis blok) – Satoshi Nakamoto ostavio je sakrivenu snažnu poruka. U toj poruci citirao je naslov objavljen 3.siječnja 2009. godine u novinama The Times koji kaže: Premijerka samo što nije odobrila drugi paket mjera kako bi se spasile banke. („Chancellor on brink of second bailout for banks“).

Satoshi Nakamoto je ovim činom izrazio svoju kritiku prema državama i političarima koji njima upravljaju a koja je zajednička svim Cypherpunksima. Tokom financijske krize 2008. središnje državne banke u optjecaj pustile su goleme količine novo isprintanog novca kako bi spasile banke. Cijenu tog spašavanja platili su obični ljudi poput mene i vas jer je naš novac i naša ušteđevina izgubila vrijednost. Vrijednost je izgubila jer je novac koji je stvoren iz ničega i dan bankama obezvrijedio naš novac koji je zarađen radom. Puštanje novca u optjecaj na ovakav način uzrokuje inflaciju a inflaciju najlakše opisujemo kao smanjenje kupovne moći. Svima je jasno i svi na svojoj koži osjećaju da 100 eura danas može kupiti puno manje nego je tih istih 100 eura moglo kupiti prije godinu dana. To je inflacija ili skriveni porez koji svi mi zajedno plaćamo. Ali mi ga plaćamo novcem koji moramo zaraditi a države i banke ga plaćaju novcem koji si stvore prema potrebi i u količinama koje su im potrebne. To je surova realnost današnjeg svijeta i to je razlog nepovjerenja Cypherpunksa u države i njihove središnje banke te je učvrstila njihovo uvjerenje da je svima potreban novac koji je apsolutno odvojen od države koja njime upravlja.

Danas, svi oni koji su u potpunosti shvatili ovo, odnosno razumjeli bitcoin ujedinjeni su u borbi, u mirnom prosvjedu kojim se traži odvajanje države od novca.

Ista situacija, samo u obimu koji je značajno veći od onoga u 2008/2009. ponovila se nakon izbijanja Covid-19 histerije. Samo u 2020., u SAD-u količina novca u optjecaju povećana je za gotovo 50%. Europska Unija nije ništa bolja po tom pitanju. Printeri novca se ne gase kako se to popularno kaže. Posljedice toga su iznimno niske kamatne stope a lako dostupan novac diže cijene svih dobara i usluga. Povećanje cijena obezvrjeđuje novac onima koji ga štede i to je inflacija.

Kako se zaštiti od obezvrjeđivanja novca

Bitcoin je pokrenut vjerojatno u najboljem mogućem trenutku. Rijetko kada je pitanje novca bilo relevantnije nego danas. Sa svojom apsolutno ograničenom količinom od 21 milijun, bitcoin predstavlja potpunu suprotnost beskrajno rastućim bilancama stanja središnjih banaka. Njegova ograničena količina predstavlja zaštitu od obezvrjeđenja vašeg novca, kao što je to slučaj sa svim danas izdanim valutama od strane centralnih banaka koje svakodnevno gube vrijednost.

Zbog svog jedinstvenog dizajna, bitcoin je stvoren da osigurava očuvanje kupovne moći tijekom dugog vremenskog razdoblja. Budući da je bitcoin sam po sebi već rijedak, u svojstvu očuvanja vrijednosti bolji je čak i od zlata. Nova količina zlata koja dolazi u optjecaj svake godine kreće se otprilike od 1-2% godišnje u odnosu na postojeću dostupnu količinu zlata. Osim toga, troškovi pohrane i „transporta“ bitcoina u usporedbi sa zlatom znatno su niži, što također dodaje vrijednost tijekom vremena.

Zaštita imovine

Još jedan problem koji bitcoin savršeno rješava je zaštita imovine. Gotovina ili zlato da bi se zaštitili od krađe moraju se pohraniti najčešće u bankovnim sefovima a to sa sobom povlači znatne troškove (posebno u slučaju zlata). Pokušajte si samo zamisliti troškove transporta i osiguranja zlata sa jednog mjesta na drugo ili iz jedne u drugu zemlju. Bitcoin je potpuna suprotnost tako nečemu. Trošak pohrane i „transporta“ bitcoina gotovo je ravan nuli. Čak i znatne količine bitcoina koje pojedinac želi premjestiti sa jednog dijela svijeta na drugi (milijarde eura vrijednosti) imaju isti trošak kao i da želi premjestiti samo nekoliko eura vrijednosti. Svaki pojedinac to može učiniti na isti način a to je da zna svoj privatni ključ s kojim pristupa svojem bitcoina a koji se najčešće sastoji od sekvence os 12 ili 24 riječi. Jednom memorirana i nakon toga fizički uništena sekvenca riječi zauvijek osigurava da vaš bitcoin ne može biti ukraden ili oduzet. Ta riječna sekvenca osigurava vaš bitcoin na blockchainu i omogućuje vam da mu pristupite bilo kada i bilo gdje na svijetu. Osigurava vam da ukoliko to želite, svoj bitcoin sa sobom ponesete i u grob.

Kako bitcoin funkcionira

Osnovna zamisao iza Bitcoin mreže je ta da je ona decentralizirana. Pod pojmom decentralizacije prvenstveno se podrazumijeva da ni jedan sudionik mreže samostalno nema mogućnost da nameće ili mijenja pravila na temelju kojih mreža funkcionira. Upravljanje mrežom je decentralizirano i moć upravljanja raspoređena je svima koji u mreži sudjeluju. Ovo je fundamentalna osobina mreže je ni jedan pojedinac, ni jedna tvrtka niti bilo koja vlada neke države nije u mogućnosti „zauzeti“ mrežu i samostalno promijeniti pravila. Pravila se mogu izmijeniti samo zajedničkim konsenzusom svih sudionika na mreži.

Veoma pojednostavljenim jezikom, funkcioniranje Bitcoin mreže bazira se na tome da svaki sudionik mreže (tu se podrazumijevaju sudionici koji imaju pokrenut Bitcoin node ili mrežni Bitcoin čvor) u svakom trenutku na svom mrežnom čvoru ima identičnu kopiju knjige svih transakcija (tzv. Bitcoin ledger ili glavna knjiga). Kako rezultat toga, svi sudionici na mreži uvijek znaju tko posjeduje koju količinu bitcoina. Nitko ne može tvrditi da posjeduje određenu količinu bitcoina koju zapravo ne posjeduje jer se to jednostavno može provjeriti u vlastitoj kopiji knjige svih transakcija koja je pohranjena na vašem mrežnom čvoru.

Prije nastanka Bitcoina, decentralizirane mreže uvijek su se suočavale s dva velika izazova. Prvi izazov bio je kako osigurati da svaki sudionik na mreži dobije najnovija ažuriranja koja sadrže sve informacije o promjenama u vlasništvu odnosno informacije o tome koliko bitcoina promijenilo vlasnika. Drugi izazov bio je kako sudionici mreže mogu s apsolutnom sigurnošću potvrditi da su informacije koje su zaprimili o promjenama u vlasništvu apsolutno točne.

Lanac blokova (Blockchain)

Lanac blokova ili blockchain tehnologija dala je odgovor na ova pitanja. Korištenjem blockchaina informacije se pohranjuju kronološkim redom kako i nastaju. U slučaju bitcoina sve informacije od samog puštanja u rad mreže pohranjene su u stotinama tisuća blokova koji su međusobno povezani i koji zajedno čine lanac blokova odnosno blockchain. Svaki sudionik mreže ima mogućnost provjeriti tko posjeduje koju količinu bitcoina prateći povijest transakcija na blockchainu. Dakle, ako netko želi poslati bitcoin nekome drugome jednostavno je za provjeriti da li on zaista i posjeduje tu količinu bitcoina.

Sigurno se pitate pa da, ali ovaj mehanizam uopće nije revolucionaran kako je to predstavljeno. Svaka banka danas ima identičan zapis (bazu podataka) u kojoj u svakom trenutku može provjeriti koje je stanje na račun bilo kojeg korisnika ili provjeriti povijest svih njegovih transakcija. Ako npr. neki klijent banke želi poslati određenu količinu eura sa svojeg računa na neki drugi račun banka će jednostavno provjeriti da li korisnik na svom računu ima potrebnu količinu eura za slanje ili je ta količina eura već potrošena pa stoga takvo transakciju nije moguće obaviti. Jedinstvena karakteristika bitcoin blockchaina za razliku od baze podataka koju ima banka je ta da isti nije pohranjen na samo jednom centralnom mjestu (središnjem serveru banke) nego je identična kopija pohranjena na svim računalima (bitcoin mrežnim čvorovima) koji se danas nalaze u gotovo svakom kutku svijeta i kojih je danas već preko 30.000. Ova karakteristika je ujedno i razlog zašto Bitcoin mrežu nije jednostavno „napasti“, zaustaviti ili ugasiti. Da bi se tako nešto izvelo potrebno je ugasiti apsolutno svaki bitcoin čvor na svijetu istovremeno.

Međutim, blockchain se susreće s izazovom da svaki sudionik mreže s apsolutnom sigurnošću može potvrditi da li je njegova kopija lanca blokova točna i da pogrešne ili lažne transakcije ne budu unešene u njegovu kopiju glavne knjige. Budući da se novi blokovi (blokovi sadrže novonastale transakcije) dodaju u blockchain otprilike svakih 10 minuta, veličina blockchaina konstantno raste i mora se kontinuirano ažurirati na svim računalima koja su priključena na mrežu.

Svi novi blokovi koji se nadovezuju na postojeći lanac blokova moraju se moći provjeriti od strane svakog mrežnog sudionika. Ova provjera vrši se pomoću pravila koja su definirana u računalnom kodu Bitcoin mreže i koja ne mogu biti izmijenjena. Ova pravila točno definiraju koje transakcije su dopuštene, a koje nisu. Svaki korisnik koji preuzme kopiju blockchaina na svoje računalo može provjeriti jesu li sve transakcije u skladu s postavljenim pravilima. Ako neka nova transakcija nije u skladu s pravilima tj. ako je netočna ili lažna, sudionici mreže je odbijaju (sudionici mreže koji na svojim računalima imaju pohranjen cjelokupni lanac blokova) i ne uključuju je u blockchain.

Dokaz o radu (Proof-of-Work) i rudarenje

Bitcoin funkcionira na principu korištenja mehanizma dokaza o radu. Da bi netko u lanac blokova dodao novi blok mora pružiti dokaz o radu. Taj dokaz o radu je ujedno i mehanizam koji ograničava da u lanac blokova bilo tko i bilo kada može dodati novi blok. Da tog mehanizma nema mreža bi vjerojatno već odavno bila propala i zaboravljena. Kako bi netko pronašao novi blok i uključio ga u postojeći lanac blokova mora uložiti rad u njegovo pronalaženje. Kao nagradu za pronalazak bloka i njegovo uključivanje u lanac blokova nalaznik je nagrađen novim bitcoinom kao i transakcijskim naknadama sadržanim u ovom novom bloku. Nakon što je novi blok pronađen i dodan u lanac blokova ovaj proces započinje ispočetka.

Ovaj proces traženja novog bloka naziva se rudarenje. U procesu ovog digitalnog rudarenja, rudari su ti koji na svojim specijaliziranim računalima izvršavaju matematičku hash funkciju (SHA-256 algoritam) u potrazi za određenim brojevima. Hash broj prethodnog bloka, transakcije trenutnog bloka i nasumični broj (nonce) zajedno se stavljaju u hash funkciju. Ovaj nasumični broj mijenja se sve dok hash funkcija kao rezultat ne izbaci rezultat s minimalnim brojem potrebnih vodećih nula. Na primjer, blok 767700, pronađen 16. prosinca 2022. godine, imao je važeći hash broj: 00000000000000000001f923407f16129a16e0b15122f6750444b44ceff86c37.

Proces rudarenja ima dvije primarne funkcije: Prva je da blokove povezuje na matematičko-kriptografski način tako da svi koji to žele jednostavno mogu provjeriti redoslijed njihovog nastanka. Istovremeno, mehanizam dokaza rada gotovo nemogućim čini da se taj redoslijed stavljanja blokova u lanac izmjeni. Druga funkcija je ta da isti taj mehanizam dokaza rada funkcionira na način da svaki novi blok u lanac blokova dodaje otprilike svakih 10 minuta. To vrijeme između dva nova bloka dovoljno je da svi sudionici na mreži diljem svijeta imaju dovoljno vremena da svoju kopiju blockchaina ažuriraju na najnovije stanje.

Kao zaključak, rudari su ti koji održavaju Bitcoin mrežu aktivnom. Procesom rudarenja, sve nove transakcije se obrađuju i dodaju u lanac blokova. Bitcoin čvorovi (node) čuvaju kopije glavne knjige. Programski kod koji se na njima izvršava brine se da se poštuju pravila i osigurava da nijedna lažna transakcija ne bude dodana u lanac blokova.

21 milion

Ukupan broj bitcoina koji ikada može biti kreiran je 21 milion. To je definirano osnovnim programskim kodom na kojem bitcoin počiva i ta konstanta ne može biti izmijenjena. Kako se svakih desetak minuta u lanac blokova dodaje novi blok kao posljedica dokaza rada rudara, tako oni za svaki taj novi blok pripojen postojećem lancu blokova dobivaju bitcoin kao nagradu. Visina te nagrade za svaki novi blok također je definirana osnovnim programskim bitcoin kodom. Kao i u prethodnom slučaju ta konstanta također ne može biti izmijenjena. Raspored izdavanja novog bitcoina rudarima za njihov rad poštuje strogi raspored.

Kada je Bitcoin mreža tek pokrenuta, programski kod je rudarima dodjeljivao 50 novih bitcoina za svaki novi blok dodan u lanac blokova odnosno otprilike svakih desetak minuta. Četiri godine nakon pokretanja Bitcoin mreže, broj bitcoina koji se dodjeljuje rudarima za njihov rad se prepolovio i iznosio je 25 novih bitcoina za svaki novi blok odnosno svakih desetak minuta. Taj predefinirani proces naziva se prepolovljavanje (halving). Do prepolovljavanja broja bitcoina koji se dodjeljuje rudarima za njihov rad dolazi otprilike svake 4 godine odnosno nakon 220.000 novih blokova dodanih u lanac blokova. Do danas na ovakav način izdano je već preko 19 miliona bitcoina a trenutna nagrada za novi blok iznosi 6,25 bitcoina. Slijedeći ovaj predefinirani raspored dodavanja novih blokova u lanac blokova i izdavanja novog bitcoina pretpostavlja se da će zadnji bitcoin biti izdan negdje 2140. godine. Nakon toga, rudari će za svoj rad biti kompenzirani samo kroz transakcijske naknade.

Ta apsolutno ograničena količina bitcoina koji ikada može postojati jedno je od njegovih temeljnih svojstava te ga čini iznimno rijetkom te stoga i vrijednom „robom“. Ova apsolutno ograničena količina također je važan preduvjet za funkciju bitcoina kao sredstva koje služi za pohranu vrijednosti tijekom duljeg vremenskog razdoblja i to je razlog zašto se bitcoin još naziva i digitalnim zlatom.

Uzimajući u obzir sve navedene značajke Bitcoin mreže veoma je jednostavno shvatiti važnost i vrijednost ovog izuma. Prvi put u povijesti postoji digitalna „roba“ koja ne može biti kopirana ili duplicirana nego je apsolutno ograničena brojem jedinica koje ikada mogu postojati.

Ove jedinice bitcoina se doista mogu posjedovati. Samo osoba koja posjeduje odgovarajući privatni ključ (privatni ključ se može smatrati i kao lozinka) kojim se pristupa nekoj bitcoin adresi na kojoj se određena količina bitcoina nalazi, može taj bitcoin poslati nekome drugome na neku drugu bitcoin adresu. Bez ovog privatnog ključa bitcoinu u nečijem vlasništvu nije moguće pristupiti te stoga niti moguće ukrasti, zaplijeniti ili blokirati. Vlasniku tog bitcoina koji je zaštićen privatnim ključem omogućena je apsolutna kontrola nad svojim financijskim resursima, bez obzira da li je taj pojedinac bogat, siromašan ili kriminalac, bez obzira da li je politički disident ili izbjeglica, bez obzira odakle dolazi ili koja su njegova vjerska uvjerenja. Po prvi put od izuma računala, moguće je uistinu posjedovati digitalnu imovinu.

Više na ovu temu možete pročitati u ovom blogu.

Izum i nastanak Bitcoina

Kada govorimo o bitcoinu i njegovim počecima moramo se vratiti sve do početka devedesetih godina prošlog stoljeća. Davne 1992. godine grupa računalnih stručnjaka, istomišljenika iz Kaliforniji okupila se na jednoj email listi putem koje su razmjenjivali ideje o kriptografiji, matematici, politici i filozofiji. Nazivali su se „Cypherpunks“. – igra riječima koji dolazi od cyberpunka (osoba iz sci-fi, znanstveno-fantastične literature koja je skeptična prema društvu općenito) i riječi cipher koja znači nešto šifrirati.

Cypherpunksi su ubrzo postali veoma šarolika ekipa koja je dolazila iz svih krajeva svijeta. Unatoč svojim različitim uvjerenjima oko svega i svačega, zajedničko uvjerenje im je bilo da da će internet uskoro postati jedno od najspornijih područja ljudske slobode. Kako bi se zaštitili od rastućih mehanizama kontrole, nadzora i cenzure na internetu te kako bi očuvali slobodan i otvoren internet, Cypherpunksi su upotrijebili moćno „oružje“: kriptografiju. Informacije koje su međusobno dijelili uspješno su šifrirali tako da nisu mogle biti vidljive onima kojima te informacije nisu bile namijenjene.

Cypherpunksi su u svom manifestu iz 1993. izjavili: “Cypherpunksi pišu [računalni] kod. Znamo da netko mora napisati softver za obranu privatnosti, a budući da ne možemo dobiti privatnost ako to ne učinimo svi, mi ćemo ga napisati.“

Kriptografija sama po sebi nije dovoljna za slobodan internet. Cypherpunksi su bili svjesni da Internet ne može biti uistinu slobodan ako nema svoj vlastiti novac odnosno valutu. Novac koji je neovisan o državama, središnjim bankama i tvrtkama; kripto valuta koja je pravedna i decentralizirana baš kao i sam Internet.

Put do bitcoina

Put do funkcionalnog i neovisnog digitalnog novca isprepleten je mnogobrojnim tehničkim izazovima. Davne 1990. godine kriptograf David Chaum stvorio je eCash koja se smatra prvom kripto valutom. Iako nije bila decentralizirana, zahvaljujući tada već poznatim metodama kriptografije osiguravala je dovoljnu razinu anonimnosti. Usprkos tome, eCash se nije uspio nametnuti kao dovoljno jak igrač te je izgubio tržišnu utakmicu u srazu sa ostalim kompanijama koje su razvijale sustave plaćanja koji bi se koristili na mreži odnosno na Internetu. Tvrtka koja stoji iza eCash projekta nakon nekoliko godina postojanja podnijela je zahtjev za stečaj te je eCash kao projekt ugašen.

Bilo je i dosta drugih pokušaja stvaranja sustava plaćanja koji bi nativno služili za plaćanja na mreži a među njima se ponajviše istaknuo projekt E-Gold. E-Gold je bila kripto valuta koja je svoje pokriće imala u zlatu i bila je otvorena svima koji su ju željeli koristiti. E-Gold projekt pokrenut je tijekom dot-com ere 1996. godine. Na svom vrhuncu putem kripto valute procesuirano je transakcija ukupne vrijednosti gotovo 2 milijarde američkih dolara.

Problem E-gold projekta je bio taj što je bio kontroliran od strane jedne središnje institucije i stoga je bio osjetljiv na napade (eng. single point of failure). Kada je E-Gold postao poznato ime na tržištu uslijedili su problemi pravne prirode. Američka vlada poduzela je pravne korake kako bi zaustavila daljnji razvoj projekta i njegovo širenje na tržištu. Američki sud 2008. godine proglasio je E-Gold krivim pod optužbom za pranje novca i kršenje Patriot Acta. Iz tog razloga projekt E-Gold moramo je biti ugašen te je sva imovina zamrznuta i oduzeta.

Ova dva i još nekoliko sličnih propalih projekata ukazali su na dvije jako bitne činjenice. Prvo, i eCash i E-Gold imali su kolateral koji je na neki način bio garancija i odraz njihove vrijednosti. Upravo ti kolaterali pokazali su se kao slaba točka jer su ga vlade država jednostavno mogle zaplijeniti. Iz tog razloga, kripto valuta kojoj su težili Cypherpunksi nije smjela imati jednu slabu odnosno centralnu točku napada kao npr.: da iza nje stoji neka kompanija sa bankovnim računom, da ima pohranjen kolateral (zlato) u nekoj od banaka ili da se nalazi smještena na nekom centraliziranom web serveru. Drugo, da vlade i regulatori nemaju interesa oko digitalnog novca koji je neovisan o državi.

Nakon ovakvih slučajeva i dalje je postojalo pitanje na koje odgovora još uvijek nije bilo. Kako uspostaviti nezavisan digitalni novac koji neće imati entitet koji će iza njega stajati i koji će voditi evidenciju o svim transakcijama i osiguravati da jedan iznos ne može biti dva puta potrošen (double spend problem). Uostalom, kada bi i bilo moguće riješiti problem dvostrukog trošenja bez oslanjanja na jedan centralni entitet, moguće bi bilo stvoriti „besplatni“ digitalni novac koji je komplementaran i prirodan dodatak Internetu.

Besprijekoran i mističan čin nastanka

Svi ovi prethodno navedeni razlozi tjerali su Cypherpunkse da razmišljaju o načinu kako dizajnirati kripto valutu koja neće imati jedan centralni entitet koji će iza nje stajati te koja neće imati kolateral. Dva najpoznatija koncepta koji nikada nisu zaživjeli bili su b-money (1998) i BitGold (2005). Ta dva teoretska koncepta svojim dizajnom najviše su se približili bitcoinu. Par javnog i privatnog ključa bio je osnova za enkripciju, dok je dokaz rada (Proof-of-Work) trebao poslužiti kao sredstvo koje će se koristiti za izdavanje novih količina digitalne valute koina (Coins). U svom „manifestu“ u tzv. bijeloj knjizi (Whitepaper), tvorac bitcoina je potvrdio da je prije objave svog rješenja bio upoznat s konceptima b-money i Bit Gold.

Međutim, ova dva koncepta oslanjala su se na sistem glasovanja kojim se upravlja temeljnim konsenzusom protokola („dogovor“ oko toga tko je vlasnik koje količine monetarne vrijednosti u datom trenutku). Taj sustav glasovanja je bio slaba točka oba konceptualna rješenja. Predstavljao je potencijalni vektor napada zlonamjernih strana putem kojeg se moglo utjecati na izbore prilikom glasanja o izmjenama temeljnog konsenzusa i na taj način se moglo utjecati na količinu izdanog digitalnog novca te ograničavanje prava vlasništva.

Rješenje za ovaj posljednji problem, koji je još nije bio riješen na putu stvaranja novog internetskog novca, predstavljeno u petak, 31. listopada. 2008 godine. Toga je dana Cypherpunksima na njihov email poslan Bitcoin Whitepaper, u kojem Satoshi Nakamoto objašnjava svoj koncept decentralizirane mreže za plaćanja na internetu. Dva mjeseca kasnije, 3. siječnja 2009., Bitcoin mreža puštena je u rad i do dan danas nikada nije imala niti jednu sekundu da nije bila aktivna.

Prve reakcije na ovu novu mrežu nisu bile previše zapažene. Nekoliko entuzijasta sa email liste Cypherpunksa počelo je mrežu testirati i prijavljivati pogreške. U početku je, međutim, uglavnom sam Satoshi Nakamoto održavao mrežu. Ali vijesti o novom Internetskom novcu polako su se počele širiti računalnim i tehničkim forumima što je dovelo do toga da je i interes za korištenjem mreže rastao iz dana u dan. Nakon godinu funkcioniranja Bitcoin mreža već bilježi znatan broj korisnika ali ipak, sam bitcoin još uvijek nije imao monetarnu vrijednost.

Satoshi Nakamoto

Ime Satoshi Nakamoto pojavilo se i na Bitcoin Whitepaperu i u potpisu emaila poslanog na prethodno spomenutu email listu. Stvarni identitet tvorca Bitcoina i dan danas je još uvijek nepoznat. Iz svih dostupnih podataka i mnogobrojnih istraživanja na tu temu daje se zaključiti da je ime Satoshi Nakamoto ipak samo nadimak a ne pravo ime stvarne osobe. Satoshi Nakamoto za svoju korespondenciju koristio je tri različite email adrese koja je jako dobro kriptirao tako da se stvarnom pošiljatelju tih mailova nikada nije uspjelo ući u trag.

Do danas, mnogi pojedinci pokušali su uz svoje ime vezati genijalnost koja stoji iza izuma bitcoin i sebe proglasiti Satoshi Nakamotom. No ipak, do sada nitko od njih nije uspio pružiti definitivne dokaze za to. Nitko od svih ovih lažnih pretendenata na tron nije dokazao da kontrolira adrese za koje se pretpostavlja da se na njima nalazi bitcoin koji pripada Satoshi Nakamotu. Da bi netko dokazao da je tvorac bitcoina mora biti u mogućnosti sa tih adresa poslati bitcoin na neku drugu bitcoin adresu. To može jedino ako posjeduju privatne ključeve za te adresu s kojima može potpisati transakciju s kojom bi bitcoin bio poslan na neku drugu adresu. Do danas, nitko nije pružio dokaz za to.

Danas postoji relativno mali broj ljudi koji su „osobno” (putem interneta) komunicirali sa Satoshi Nakamotom. Dana 12. prosinca 2010., Satoshi Nakamoto je poslao svoju posljednju poruku široj Bitcoin zajednici. Nakamoto je nastavio komunicirati sa užim krugom programera i nastavio ih informirati o stanju Bitcoin mreže. Tokom travnja 2011. godine Satoshi Nakamoto poslao je svoju zadnju poruku i ovom najužem krugu programera. Nakamoto se nakon ovoga do danas više nikada nikome nije javio. Kako se misteriozne pojavio 2008. tako je i misteriozno nestao 2011. godine.

Genesis address ili prva adresa ikad na koju je poslan bitcoin je A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa. Za tu adresu se smatra da je u vlasništvu Satoshi Nakamota koji je osobno na nju poslao bitcoin koji je inicijalno izrudaren. Ukoliko upotrijebite bitcoin block explorer (pretraživač bitcoin blokova) na web stranici www.mempool.space možete vidjeti da je ta adresa primila bitcoin u više od 3,500 transakcija dok ne postoji niti jedna transakcija koja pokazuje da je sa te adrese bitcoin poslan na neku drugu adresu. Zasigurno se pitate zašto je u više od 3,500 transakcija bitcoin poslan na prvu ikad stvorenu bitcoin adresu. Sve te transakcije sadrže neki mali, simboličan iznos bitcoina ali se mogu shvatiti kao čin odavanja počasti tvorcu bitcoina Satoshi Nakamotu.

Bitcoin Pizza

Kako je Bitcoin u početku zapravo stekao svoju vrijednost? Bitcoin se u početku mogao „rudariti“ i slati među korisnicima mreže ali sam po sebi nije imao nikakvu monetarnu vrijednost. Pored toga, jako mali broj ljudi je uopće znao za bitcoin i kako ga koristiti.

Prva događaj koji je bitcoinu ikad dodijelio neku monetarna vrijednost dogodio se 22.svibnja.2010. godine kada se na bitcointalk.org forumu pojavio neobičan oglas. Tada 28-godišnji muškarac po imenu Laszlo Hanyecz s Floride ponudio je 10.000 bitcoina u zamjenu za dvije pizze koje će biti dostavljene na njegovu adresu. Tu ponudu je prihvatio jedan student iz Californije koji je na njegovu adresu poslao dvije pizze u vrijednosti od 41$. Za uzvrat, Laszlo Hanyecz poslao mu je 10.000 bitcoina. Od tog dana, 22. svibanj u bitcoin zajednici slavi se kao bitcoin Pizza dan. Taj dan postao je bitan jer je definirao 3 stvari:

• bitcoin je od tada imao vrijednost,
• bitcoin je prikladan kao sredstvo razmjene i plaćanja i
• bitcoin kao valuta je deflatoran (broj bitcoina koji tokom vremena ulaze u cirkulaciju je sve manji i manji te je to pretpostavka za povećanje njegove vrijednosti)

Te dvije pizze bit će zapamćene kao dvije najskuplje na svijetu ikada. Ukoliko se u obzir uzme najveća do sada ikad zabilježena cijena bitcoina od otprilike 69.000 dolara te dvije pizze plaćene su 690 miliona dolara. Isto tako, primatelj tih 10.000 bitcoina iste je također nedugo nakon što ih je dobio prodao te je s tim novcem financirao privatno putovanje. Primjenjujući istu logiku najviše cijene bitcoina može se zaključiti da je to putovanje vjerojatno najskuplje ikad plaćeno putovanje.

Ovaj primjer s pizzom najbolje ilustrira veoma popularan izraz među ljudima koji bitcoin drže na duge staze. Izraz HODLing izvedenica je iz engleske riječi holding što znači držati. Držanje bitcoina u ovom smislu podrazumijeva držanje bitcoina „zauvijek“. Zašto bi netko uopće prodao svoj bitcoin ako je gotovo izvjesno (što i povijesni podaci pokazuju) da će vrijednost bitcoina s protekom vremena samo rasti.

Što bitcoinu daje vrijednost

Najveću vrijednost bitcoinu daje njegova iznimna rijetkost. Maksimalna količina bitcoina koja ikada može postojati je 21 milijun (21.000.000). Svatko tko ima pristup najobičnijem računalu može jednostavno sam za sebe provjeriti tu osobinu bitcoina. Ogromna računalna snaga dedicirana je konstantno kako bi se osiguravala točnost i ispravnost decentralizirane glavne knjige bitcoina. Glavna knjiga (Ledger) je zapis svih transakcija koje su se ikada na Bitcoin mreži desile. Mreža doslovno plaća ljudima da održavaju taj integritet (u obliku nagrada za rudarenje) i da djeluju u dobroj vjeri. Cijena bitcoina jednostavno je određena ponudom i potražnjom za njim na burzi.

Isto tako, bitcoin se može promatrati sa stajališta evolucije novca. Koristeći modernu terminologiju, novac se uvijek razvija u sljedeće četiri faze:

1. Kolekcionarski predmeti: U prvoj fazi svoje evolucije, novac će se tražiti isključivo na temelju njegovih osebujnih svojstava. Predmeti u ovom stadiju najčešće su strast kolekcionara ili manjeg kruga posjednika. Školjke, perle i zlato bili su kolekcionarski predmeti prije nego što su prerasli u više kategorije oblika novca.
2. Pohrana vrijednosti: Nakon što ga bude tražen od dovoljnog broja ljudi zbog svojih osobitosti, novac će biti prepoznat kao sredstvo očuvanja i pohranjivanja vrijednosti tijekom vremena. Kako neko dobro sve više poprima značajke skladišta vrijednosti, njegova će kupovna moć rasti jer ga sve više ljudi želi koristiti za ovu svrhu. Kupovna moć pohranjene vrijednosti naposljetku će doći do svog maksimuma kada to dobro bude široko zastupljeno i smanji se priljev novih ljudi koji ga žele koristiti kao skladište vrijednosti.
3. Sredstvo razmjene: Kada se novac u potpunosti ustoliči kao sredstvo očuvanja vrijednosti, njegova će se kupovna moć stabilizirati. Nakon stabilizacije kupovne moći, oportunitetni trošak korištenja novca za obavljanje poslova smanjit će se do razine na kojoj je prikladan za korištenje kao sredstvo razmjene. U najranijim danima bitcoina, mnogi ljudi nisu cijenili ogromne oportunitetne troškove korištenja bitcoina kao sredstva razmjene, a ne kao početke ere u kojem je dobro služilo u svrhu pohrane vrijednosti. Široko je poznata priča o čovjeku koji je zamijenio 10.000 bitcoina (vrijednih otprilike 225 milijuna dolara u vrijeme pisanja ovog teksta ili 690 milijuna dolara na vrhuncu vrijednosti tokom 2021. godine) za dvije pizze ilustrira ovu situacija. U svijetu bitcoina 22.svibanj svake godine obilježava se kao bitcoin pizza day. Mnogo manje poznata situacija dolazi sa naših prostora, a tiče se identične situacije kada je dotični gospodin za 20.000 kuna prodao 120 bitcoina koji bi trenutno vrijedili 2 ,7 milijuna dolara ili na vrhuncu vrijednosti 2021. godine oko 8,3 milijuna dolara.
4. Obračunska jedinica: Kada se novac naširoko koristi kao sredstvo razmjene, roba će se na tržištu cijeniti u odnosu prema njemu. Uobičajena je zabluda da su danas cijene izražene u bitcoinu dostupne za mnoge robe i usluge. Na primjer, iako bi se šalica kave mogla platiti bitcoinom, navedena cijena nije prava cijena bitcoina; nego je to cijena u dolarima koju ugostitelj traži za tu šalicu kave koja je samo prevedena u bitcoin termine po trenutnom tržišnom tečaju dolara za bitcoin. Ako bi cijena bitcoina pala izraženo u dolarima, broj bitcoina koje ugostitelj traži bi se proporcionalno povećao. Tek kada su ugostitelji (pa tako i svi ostali trgovci) voljni prihvatiti bitcoin za plaćanje bez obzira na tečaj bitcoina u odnosu na fiat valute, možemo doista misliti da je bitcoin postao obračunska jedinica.

Bitcoin se trenutno nalazi u drugoj fazi (pohrana vrijednosti). Vjerojatno će proći još nekoliko godina prije nego što bitcoin prijeđe u treću fazu gdje će postati sredstvo razmjene. Iako se kao sredstvo razmjene danas već koristi to još uvijek nije toliko rasprostranjeno da bi se moglo smatrati da je već u ovoj fazi. Kao sredstvo razmjene bitcoin se najviše koristi putem Lightning mreže. Zanimljivo je za primijetiti da je za isti prijelaz zlatu trebalo mnogo stoljeća.

Tko kontrolira mrežu

Jednostavan odgovor je i svi i nitko. Mreža je projektirana tako da se zlonamjerni akteri ne mogu okoristiti, a svatko ima kontrolu nad svojim sudjelovanjem u njoj. Nijedan programer samostalno ne može izvršiti nikakve promjene bitcoin koda. Nijedan rudar nije u mogućnosti filtrirati bilo koju određenu transakciju. Niti jedan korisnik bitcoin mreže ne može iskoristiti mrežu na način da potroši bitcoin koji mu ne pripada ili koji nema.

Da li je korištenje bitcoina anonimno

Bitcoin na razini mreže nije “povezan” ni s jednim javnim identitetom. Protokol prepoznaje adrese samo kao zbirku slova i cijelih brojeva. Međutim, poslovni subjekti koji svoje poslovanje temelje na Bitcoinu, poput KYC (know your customer) burzi na kojima je moguće kupiti bitcoin, mogu povezati bitcoin koji tamo kupite s vašim identitetom u stvarnom svijetu. Budući da je glavna knjiga bitcoina (bitcoin ledger) u potpunosti vidljiva svima, može doći di situacije da je zbog toga moguće pratiti nečije bitcoin transakcije.

Što je to blockchain

Zapis o svakoj bitcoin transakciji ikad napravljenoj čuva se na blockchainu u tzv. javnoj knjizi odnosno bitcoin ledgeru. U zamjenu za transakcijske naknade i subvenciju za blok, rudari se natječu u „proizvodnji“ blokova. Svaki uspješno zapisani novi blok kriptografski je povezan sa blokom koji mu prethodi te se na taj način stvara lanac blokova ili blockchain. Za potpuno razumijevanje kako blockchain funkcionira pročitajte blog na ovom linku.

Može li država ili vlada zaustaviti bitcoin

Nema sumnje da bi vlade mogle zabraniti bitcoin unutar svojih granica. U stvarnosti, Kina je to već učinila nekoliko puta, a ekosustav još uvijek napreduje. Zbog disperzirane arhitekture bitcoina, zaustavljanje njegove ekspanzije zapravo bi zahtijevalo goleme koordinirane napore mnogih velikih svjetskih zemalja. Takvi napori da se uništi mreža zahtijevalo bi izrazito velike financijske resurse a s time se zapravo ništa ne bi dobilo. Priključiti se i koristiti bitcoin mreže jednostavno može svatko sa najjednostavnijeg osobnog računala tako da je malo vjerojatno da bi se vlade ozbiljnih država upustile u tako nešto jer bi vjerojatno došlo do potpuno suprotnog efekta.

Da li ga koriste kriminalci

Budući da je Bitcoin oblik valute, kriminalci ga mogu koristiti identično kao i što koriste svaku drugu valutu. Ilegalno tržište drogama danas se pretpostavlja da vrijedi više od 500 milijardi dolara godišnje. Ako se to usporedi s današnjom cijenom bitcoina od oko 20.000 dolara i ukupnom tržišnom kapitalizacijom od nešto više od 400 milijardi dolara može se reći da bitcoina zapravo nema dovoljno da pokrije sve potrebe ilegalnog tržišta drogama. Zasigurno je točnije utvrditi da se fiat valute (poput dolara ili eura) koriste za financiranje velike većine ilegalnih aktivnosti na tom tržištu. Isto tako, s obzirom da znamo da su bitcoin transakcije u potpunosti transparentne i vidljive svima, jedna od najglupljih stvari koje kriminalne organizacije povezane s drogama mogu napraviti je da svoje tragove odnosno izvršene transakcije ostave na blockchainu koji nije moguće izmijeniti a u svakom trenutku se mogu pregledati.

Isto tako, prema istraživanju tvrtke Chainalysis, tvrtka za analizu blockchaina, izvjestila je da je pranje novca činilo samo 0,05% ukupnog volumena kripto transakcija u 2021. To bi značilo da je od 2017. do danas oprano 33 milijarde dolara putem kripto imovine. Za usporedbu, UN-ov Ured za droge i kriminal procjenjuje da se 800 milijardi do 2 trilijuna dolara svake godine opere korištenjem klasičnih fiat valuta (dolar, euro itd.), što je oko 5% globalnog BDP-a.

S obziron na navedeno, argument da se bitcoin i ostale kripto valute koriste za ilegalne aktivnosti je u potpunosti promašen i lažan narativ institucija koje danas imaju kontrolu nad fiat novcem samo iz razloga kako bi opravdali svoje postojanje.

Može li se bitcoin jednostavno kopirati

Da, na razini mreže je to moguće napraviti i mnogi pojedinci su to zapravo i napravili. Danas postoje doslovno stotine Bitcoin klonova, svaki s malom izmjenom izvornog koda čija je namjena da bi se Bitcoin malo “poboljšao”. Ova “poboljšanja” gotovo uvijek uključuju značajne kompromise, sprječavajući ih da iskoriste moćne mrežne učinke Bitcoina. U stvarnosti bitcoin je jedan i jedini i nije moguće kopirati. Bitcoin je jedno a sve ostale kriptovalute su nešto sasvim drugo.

Zar bitcoin ne troši energiju

Istina je da Bitcoin mreža koristi puno energije ali ta se energija koristi za funkcioniranje i osiguranje danas najsigurnije globalne kompjuterske mreže za plaćanja a to je bitcoin mreža. Ta mreža za direktna plaćanja i pohranu vrijednosti pojedincima nudi ogromnu vrijednost te se energija utrošena za tu svrhu nikako ne može smatrati bespotrebno potrošenom. Vlasnici bitcoin farmi (pogona za rudarenje bitcoina) već su odavno započeli s inovacijama u korištenju alternativnih izvora energije kao što su obnovljivi izvori energije ili korištenje plinova koji se inače spaljuju prilikom vađenja nafte.

Koliko bitcoina postoji

U trenutku pisanja ovog teksta u opticaju je nešto više od 19 milijuna bitcoina. Samo 21 milijun bitcoina će ikada postojati, a posljednji bitcoin bit će pušten u optjecaj negdje otprilike oko 2140. godine. To se možda čini jako malo za jednu globalnu mrežu za plaćanja ali isto tako mora se imati na umu da se svaki bitcoin može podijeliti na 100 milijuna manjih jedinica koje se zovu Satoshi ili sats.

Kako nastaje bitcoin

Globalno raspršenim i iznimno konkurentnim procesom rudarenja proizvodi se novi bitcoin. Rudari koji pronađu novi blok dobivaju subvenciju ili nagradu za svoj rad u obliku novo stvorenog bitcoina. Ova subvencija danas je na 6,25 bitcoina za svaki novi blok. Ove subvencije se otprilike svakih 4 godine ili 210.000 blokova prepolovljuju. Slijedeće prepolovljavanje će biti otprilike u travnju 2024. godine i tada će se za svaki novi blok dobivati nagrada od 3,125 bitcoina.

Što je rudarenje

Rudarenje je metoda kojom rudari alociraju značajne računalne resurse kako bi procesuirali transakcije na mreži u blokove. Nakon prikupljanja svih transakcija, rudari izvode ponavljajuće računske operaciju kako bi pronašli odgovor koji odgovara prethodno postavljenom kriteriju. Nakon što pronađu odgovor te transakcije se zapisuju u blok a rudar za to dobije nagradu u obliku naknada za obradu transakcija i nagradu za novostvoreni blok. Za svaki novi blok ponavlja se ovaj postupak. Više o ovoj temi pročitajte u ovom blogu.

Kako mogu kupiti bitcoin

Postoje mnoge online mjenjačnice na kojima možete kupiti bitcoin, ali prije nego što to učinite, trebali biste provesti vlastito istraživanje. Najjednostavniji način da dobijete svoj prvi bitcoin (ili samo dio bitcoina) je da kupite nešto od pouzdanog prijatelja ili vama poznate osobe. Važno je imati na umu da svaki bitcoin ima 100 milijuna Satoshia, tako da možete kupiti i manje od jednog bitcoina. Više o mjenjačnicama možete pročitati ovdje.

Što je još potrebno znati o bitcoinu

bitcoin.org vs bitcoin.com

Potrebno je naglasiti da je web stranica pravog i jedinog bitcoina bitcoin.org. S obzirom da iza pravog bitcoina ne stoji niti jedna individua, niti jedna kompanija pa tako niti jedna država morate znati da iza stranice bitcoin.com stoji privatna kompanija Saint Bitts LLC. koja na tržištu nudi komercijalne usluge koje se temelje na blockchain tehnologiji koje su najčešće vezane za neke druge kripto valute a ne bitcoin.

Digitalno zlato

Star nešto više od deset godina, bitcoin je još uvijek relativno nova tehnologija. Još uvijek nije potpuno spreman za široku upotrebu u smislu novca koji se svakodnevno koristi za razmjenu dobara i usluga. Iako je danas moguće kupovati i prodavati proizvode i usluge s bitcoinom, trenutno je njegova primarna namjena pohrana vrijednosti na duže vrijeme ili kao oblik digitalnog zlata. Danas, mnogi ljudi kupuju bitcoin i koriste ga kao spremište vrijednosti tijekom vremena zbog njegove fiksne i ograničene maksimalne količine koja ikada može postojati. Sve što može zadržati svoju vrijednost ili kupovnu moć tijekom vremena je skladište vrijednosti. Budući da sve vlade diljem svijeta printaju beskonačne količine novca (fiat novac koji svi danas koristimo), dovodi do inflacije tih fiat valuta pa posljedično tome i do inflacije cijena odnosno porasta cijena svih dobara i usluga. Zbog toga su tradicionalne valute loše „skladište vrijednosti“. U usporedbi s tim valutama i drugom imovinom, bitcoin s vremenom bolje zadržava svoju vrijednost zbog svoje fiksne ponude.

Ljudi bitcoin iz tog razloga drže kao vrstu digitalnog zlata kao zaštitu od inflacije. Bitcoin također ima brojne prednosti u odnosu na pravo zlato, uključujući mogućnost slanja gotovo odmah i za vrlo male transakcijske troškove bilo gdje u svijetu. Osim toga, pohranjivanje bitcoina je puno jednostavnije od pohranjivanja zlata. Bitcoin se može čuvati na hardverskom novčaniku, računalu, pametnom telefonu, online bitcoin mjenjačnici ili u svemu navedenom. Da biste spremili svoj bitcoin, ne morate kupovati sef ili mjesto u trezoru neke banke. Bitcoin se, za razliku od zlata, također može lako prenijeti preko međunarodnih granica, kao što je već spomenuto.

Cijena može imati velike oscilacije

Cijena bitcoina je znatno porasla jer ga koristi sve više i više ljudi širom svijeta. Vrijednost bitcoina kada je prvi put predstavljen bila je manja od jednog penija. Do danas, najveća zabilježena cijena bitcoina bila je preko 69.000 američkih dolara. Međutim, kako bitcoin prolazi kroz proces prihvaćanja, može doći do značajnih kretanja cijena na gore i dolje u kratkom vremenskom periodu. Kao rezultat toga, ulaganje u bitcoin je još uvijek rizično, a ljudi bi trebali ulagati samo ono što si mogu priuštiti izgubiti. Možda je praktičnije reći da je u bitcoin najbolje uložiti onaj novac koji vam nije potreban za esencijalne životne potrebe te da ulaganje u bitcoin treba biti dugoročnog karaktera. Svi koji su u bitcoin uložili novac i nisu ga dirali barem 4 godine nisu nikada izgubili. Oni koji su npr. uložili u bitcoin kada je bio na svom vrhu na otprilike 69.000 američkih dolara i žele ili moraju do svog novca doći sada zasigurno bi imali ostvarene gubitke jer je cijena bitcoina trenutno manja od navedenog iznosa.

Bitcoin je dugoročna investicija i s vremenom vjerojatnost je velika da će postići cijene koje su mnogostruko veće i od trenutno najveće zabilježene od 69.000 američkih dolara. Cijenom bitcoina na burzama se trguje i manipulira isto kao i sa svim ostalim cijenama dionica a s obzirom da je bitcoin veoma mlada klasa imovine podložna je većim oscilacijama u kratkom vremenskom periodu od za razliku velikih svjetskih kompanija čije dionice na burzi kotiraju desetljećima.

Volatilnost cijene bitcoina je funkcija njegovog nastajanja. U prvih nekoliko godina svog postojanja, bitcoin se ponašao kao tzv „penny-stock“, i svaki veliki kupac koji bi se eventualno pojavio uzrokovao je nagli porast cijene. Kako su usvajanje i likvidnost rasli tijekom godina, volatilnost bitcoina se proporcionalno smanjila. Kada bitcoin postigne tržišnu kapitalizaciju zlata, pokazat će sličnu razinu volatilnosti. Kada bitcoin premaši tržišnu kapitalizaciju zlata, njegova volatilnost smanjit će se na razinu koja će ga učiniti prikladnim kao široko korišteno sredstvo razmjene.

Transakcije se mogu pratiti

U „javnoj knjizi“ bitcoina (bitcoin ledger) svaka transakcija bitcoinom je zabilježena. Svatko na svijetu može pregledati sve transakcije pretraživanjem Block Explorera na mreži i unošenjem određene transakcije ili adrese novčanika. Koristeći kriptografsku metodu s javnim ključem, privatnim se ključem čuvaju identitet vlasnika bitcoin novčanika i adresa bitcoin novčanika. Identitet korisnika ipak može biti otkriven ako se prilikom korištenja bitcoina samoinicijativno pružaju dodatne informacije o identitetu vlasnika bitcoina. Stoga je korištenje adresa bitcoin novčanika samo jednom solidna operativna sigurnosna praksa. Danas već postoje mnoge tvrtke na tržištu koje se fokusiraju na praćenje entiteta na blockchainu. Jedna od najpoznatiji je zasigurno Chainanlysis. Tvrtka surađuje s poduzećima i vladama država kako bi „povećali transparentnost“ blockchaina, kako bi lakše identificirali određene korisnike te pružili podatke i usluge analize podataka velikim tvrtkama.

Porezi i regulativa

Korištenjem bitcoina potrebno je upoznati se i sa poreznim obvezama koje iz toga proizlaze. Velika većina država na svijetu za trgovanje bitcoinom podrazumijeva da je na takve transakcije potrebno platiti i određena davanja državi. Bitcoin se tretira kao vlasništvo te se u Hrvatskoj plaća porez na kapitalnu dobit koju ste eventualno ostvarili kao razliku između nabavne i prodajne cijene. Ako kupujete i prodajete bitcoin, trebali biste se adekvatno pripremiti za rješavanje poreznih obveza. Ipak jedna dobra vijest je ta da ukoliko bitcoin držite više od dvije godine od datuma kupovine te ga tada odlučite prodati više nemate poreznu obvezu na temelju te transakcije. Kako smo već ranije spomenuli da je bitcoin primarno dugoročno spremište vrijednosti svakako bi ga trebali držati više od dvije godine. Mišljenje porezne uprave pročitajte u ovom dokumentu.

Sigurnosni savjeti za korištenje bitcoina

Enkripcija novčanika

Ukoliko ste se već odlučili da će te dio svoje imovine ipak pretvoriti u bitcoin morate biti svjesni činjenice da je bitcoin moguće i veoma lako izgubiti ako ga ne osigurate na pravi način. To ga su svjesni i hakeri čija česta meta napada postaju vlasnici bitcoina. Vaš pošteno stečen novac koji ste odlučili pretvoriti u bitcoin zaslužuje da bude sigurno pohranjen te je potrebno poduzeti nekoliko jednostavnih mjera opreza kako bi ga što sigurnije pohranili. Možda i jedna od najsigurnijih metoda zaštite je ta da informaciju o tome da ste vlasnik bitcoina jednostavno zadržite sami za sebe i to nikada ne spominjete u online svijetu.

Što se bitcoin novčanika tiče i njegove zaštite apsolutni minimum koji morate osigurati je vaš novčanik osiguran lozinkom bez obzira da li se radi o vašem osobnom novčaniku kojeg imate na računalu ili mobitelu ili novčaniku koji imate na nekoj od online mjenjačnica. Lozinke poput „123456“ ili „ivan30051980“ nisu lozinke i to ste već odavno trebali naučiti. Lozinke trebaju biti mnogo kompleksnije od ovih primjera pa ovome svakako dajte na važnosti. Lozinka bi svakako trebala sadržavati velika i mala slova kao i brojeve te specijalne simbole. Primjer jedne dobre lozinke izgledao bi ovako: „uS7Dj@85V14ez$7C“. Ukoliko se pitate kako je takvu lozinku uopće moguće zapamtiti tada možete razmisliti o korištenju password manager alata.

Ukoliko ste se odlučili za najsigurniju varijantu čuvanja vašeg bitcoina korištenjem Ledger ili Trezor hardverskih novčanika kroz proces zaštite istih biti će te vođeni prilikom njihove inicijalizacije.

Ukoliko koristite novčanike nekih od online mjenjačnica svakako je potrebno aktivirati 2FA ili dvo-faktorsku autentifikaciju. Ako ste se registrirali na mjenjačnicu koja ne pruža takvu mogućnost savjetujem vam da račun na toj mjenjačnici odmah zatvorite. Ocjenu i sigurnost pojedinih mjenjačnica možete pogledati na slijedećem linku. Dvo-faktorska autentifikacija predstavlja dodatnu razinu zaštite od neovlaštenih upada u vaš korisnički račun.

Na mjenjačnicama koje nude ovaj oblik zaštite nju je moguće aktivirati na slijedeći način: (mjenjačnice možda korite različitu terminologiju kroz izbornike ali princip je kod svih isti)

• Potrebno je preuzeti besplatnu Google Authenticator ili Authy aplikaciju putem vašeg mobilnog telefona
• Ulogirati se u vaš račun na mjenjačnici
• Otići na stranicu sa sigurnosnim postavkama i odabrati Two-Factor Authentication.
• Tada bi vam se trebao prikazati QR kod koji je potrebno skenirati sa aplikacijom koju ste preuzeli u prvom koraku
• Kada je kod uspješno skeniran aplikacija na mobitelu će vam početi prikazivati broj od 6 znamenki koji će se svakih 30 sekundi izmjenjivati
• Ovo je vaš kod za verifikaciju koji uz lozinku sada morate upisivati svaki put kada se ponovo budete pristupali svom korisničkom računu
• Mjenjačnica će vas sada zatražiti da potvrdite aktivaciju 2FA sa kodom koji se prikazuje u vašoj mobilnoj aplikaciji

Nikada ne dijeli svoje privatne ključeve

Privatni ključ je kod koji vam omogućuje prijenos bitcoina, odobravanje transakcija i općenito za kontrolu vašeg bitcoin novčanika. OD APSOLUTNE JE VAŽNOSTI DA SVOJE PRIVATNE KLJUČEVE ZADRŽITE SAMO ZA SEBE. Čuvajte ih na sigurnom mjestu kojem samo vi možete pristupiti. UKOLIKO NETKO DOĐE DO VAŠIH PRIVATNIH KLJUČEVA ON TADA IMA PRISTUP VAŠEM BITCOIN NOVČANIKU TE SA VAŠIM BITCOINOM SPREMLJENIM NA NJEGA MOŽE UČITI ŠTO GOD ŽELI.

Svoje privatne ključeve čuvajte. Privatne ključeve nikada ne čuvajte na računalu ili mobitelu ili bilo kojem drugom uređaju koji se može spojiti na Internet. Jer ako se može spojiti na Internet tada tom uređaju mogu isto tako pristupiti i hakeri ili zloćudni softver a vaši privatni ključevi tada mogu biti kompromitirani.

Poznata je uzrečica koja glasi „Not your keys not your coins“. Vašim bitcoinom upravljate samo ako imate kontrolu nad vašim privatnim ključevima. Ako nemate kontrolu nad vašim privatnim ključevima tada nemate ni kontrolu nad vašim bitcoinom.

Jednostavno kreiranje i osiguranje pohrane vlastitih privatnih ključeva moguće je pomoću vodećih hardverskih novčanika kao što su Ledger i Trezor.

Sigurnosna pohrana novčanika

Prilikom inicijalizacije Ledger ili Trezor hardverskih novčanika morate zapisati frazu za oporavak. Fraza za oporavak se sastoji od 12 ili 24 riječi koje je potrebno zapisati na zasebni komad papira koji dolazi u pakiranju sa ovim tipom novčanika. Ovo je IZNIMNO VAŽNO jer ukoliko se desi da vaš novčanik bude oštećen, izgubljen ili ukraden, koristeći frazu za oporavak, svojim sredstvima na novom novčaniku uvijek možete pristupiti koristeći frazu za oporavak.

Jednom kada ste frazu za oporavak zapisali potrebno ju je sigurno pospremiti isto kako ste pospremili i svoj privatni ključ. Dakle offline, nikako na računalu ili u mobitelu niti u bilo kojem drugom digitalnom obliku. Frazu za oporavak možete čuvati u vašem domu ili na drugom sigurnom mjestu. Svakako osigurajte da je mjesto sigurno i vama lako dostupno kako biste svom bitcoinu mogli lako i brzo pristupiti u slučaju da izgubite vaš novčanik ili da se isti jednostavno pokvari.

Detaljno o privatnim ključevima, i frazama za oporavak pročitajte u dijelu o bitcoin novčanicima.

Ažuriranje softvera novčanika

Kako biste bili sigurni da je vaš bitcoin novčanik siguran, potrebno je redovito ažuriranje softwarea novčanika kako biste bili sigurni da software ne sadrži eventualne propuste koji mogu ugroziti sigurnost vašeg novčanika. Tvrtke koje svoja programska rješenja za bitcoin novčanike pružaju na upotrebu redovito ažuriraju svoj software kako bi ga unaprijedile korisnim izmjenama i dodacima i učinile još sigurnijim u odnosu na prethodnu verziju koja je korištena. Ako redovito ažurirate software vašeg bitcoin novčanika, na taj način osigurati će te da vaš novčanik ima najnovije značajke i najbolju funkcionalnost.

Kako kupiti bitcoin

Online mjenjačnice

Najlakši i najsigurniji način za kupnju Bitcoina je kupnja putem online mjenjačnica. Neke od najpopularnijih mjenjačnica danas su Binance, FTX, Coinbase, Kraken, KuCoin, Gemini, Gate.io, Bitfinex, Bitstamp, Bybit itd. Manje, odnosno manje poznate mjenjačnice nose veći rizik prilikom korištenja istih. Uz rizik da nisu u potpunosti sigurne postoji i mogućnost da nisu u potpunosti ni usklađene sa svim zakonskim regulativama. Imajte na umu da postoji i jako puno različitih mjenjačnica koje su apsolutne prevare. Ukoliko vam se putem telegrama, twittera, discorda i ostalih online aplikacija javljaju nepoznati ljudi i promoviraju vam mjenjačnice na kojima možete sigurno trgovati i dobivati jako velike povrate na svoje uloge savjetujem vam da te ljude odmah blokirate i ni slučajno ne otvarate linkove koje su vam poslali da se na tim mjenjačnicama registrirate. Ukoliko se registrirate i pošaljete svoja sredstva na njih budite sigurni da ste ta sredstva zauvijek izgubili.

Stoga se preporuča da svoj prvi bitcoin (ili samo dio bitcoina) kupite na nekoj od najvećih mjenjačnica, dobro etabliranih imena koja su prethodno navedena. Mjenjačnicama tih tvrtki možete pristupiti putem računala ili mobitela koristeći aplikacije koje možete preuzeti u Google Play Storeu ili Apple Storeu. Iako su to najveći igrači u kripto svijetu savjetujem vam da kada kupite svoj prvi bitcoin da ga svakako pošaljete na svoj novčanik. Kako smo već spomenuli frazu „Not your keys not your coins“ znate da ako svoj bitcoin ostavite na mjenjačnici da ne posjedujete privatni ključ za bitcoin adresu na kojoj se vaš bitcoin nalazi te samim time vi nemate apsolutnu kontrolu na njim.

Da biste kupili bitcoin, prvo morate uplatiti sredstva na račun mjenjačnice, nakon čega ta sredstva možete zamijeniti za bitcoin. Mnoge mjenjačnice nude vam opciju da novac putem bankovne transakcije prebacite na njihov bankovni račun ili da bitcoin kupite koristeći vašu debitnu ili kreditnu karticu. Ukoliko se odlučite novac prebaciti bankovnom transakcijom morate znati da će se vaš novac na mjenjačnici pojaviti u roku najčešće od 1-3 radna dana. Ukoliko želite koristiti vašu karticu novac na vašem računu bit će dostupan odmah. Ali pritom imajte na umu ukoliko koristite karticu da su provizije poprilično velike i znaju biti u rasponu od najčešće 3-5% što je zaista previše. Prilikom slanja novca na svoj račun na online mjenjačnici putem bankovne transakcije najčešće nema provizije koju će vam mjenjačnica naplatiti za polog sredstava. Neki manji trošak transakcije može se pojaviti prilikom slanja novca sa vašeg računa i to ovisi o vašoj banci.

Bitcoin bankomati (ATM)

Danas postoje i bitcoin bankomati identični onim običnim bankomatima banaka koje svakodnevno koristite za podizanje gotovine. Bitcoin bankomati pružaju diskretnu opciju za kupnju i prodaju bitcoina. Ako postoji neki blizu mjesta gdje živite, oni su također praktičan način da dođete do bitcoina. Svakako imajte na umu na su troškovi transakcije na njima u najboljem slučaju na razini onih kada koristite svoju debitnu ili kreditnu karticu za kupnju bitcoina na centraliziranim mjenjačnicama.

Danas je bitcoin moguće kupiti i u poštanskim uredima ili u klasičnim mjenjačnicama koje se nalaze na svakom koraku tipa Western Union. Transakcijske naknade kod njih su također velike tako da dvaput razmilite prije nego ih koristite.

Lokacije bitcoin bankomata možete pretraživati na slijedećem linku:

Osobno od nekoga

Bitcoin možete kupiti i osobno od nekoga tko ga želi prodati. To može biti vama neka bliska ili barem poznata osoba. Isto tako, danas online možete pronaći mnogo stranica i aplikacija na kojima ljudi oglašavaju kupnju i prodaju bitcoina. U ovom slučaju budite jako oprezni jer prevaranata ima na svakom koraku. Ukoliko se odlučite na ovaj način kupovine ili prodaje bitcoina, kod osobe s kojom dogovorite transakciju inzistirajte na tome da se nađete na nekom javnom mjestu umjesto nekog parkirališta, male mračne uličice ili lokalne birtije. Nikako nije uputno ići sam na takve „sastanke“.

Bitcoin novčanici

Što je bitcoin novčanik

Poput vašeg običnog novčanika, bitcoin novčanik je način za pohranjivanje novca odnosno vašeg bitcoina. Osnovna stvar koju morate razumjeti a koja se tiče bitcoin novčanika je da bitcoin zapravo ne postoji unutar njega. Bitcoin postoji samo na distribuiranoj bitcoin knjizi (bitcoin blockchain ledger). Privatni ključevi odnosno ključevi koji su potrebni za slanje i primanje bitcoina preko te distribuirane bitcoin infrastrukture na kojoj bitcoin zapravo funkcionira čuvaju se u bitcoin novčaniku.

Što je bitcoin adresa

Niz brojeva i slova koji je specifičan samo za vaš novčanik je bitcoin adresa. Da biste primili bitcoin, morate tu adresu podijeliti s osobom koja vam želi poslati bitcoin. Preporučljivo je da nikada 2 puta ne koristite istu adresu iz sigurnosnih razloga. Bitcoin novčanici imaju mogućnost generirati beskonačan broj bitcoin adresa pa je ovu mogućnost uputno koristiti. Većina novčanika brine o tome automatski umjesto vas i generira novu adresu svaki put kada želite primiti bitcoin. Pritom uvijek znate stanje bitcoina u vašem novčaniku koji prikazuje saldo bitcoina na svim bitcoin adresama koje su za vas u njemu generirane.

Što je to fraza za oporavak

Kada inicijalizirate novi novčanik, stvara se niz od 12 ili 24 nasumično generirane riječi poznate kao “seed words” ili “mnemonic“ odnosno fraza za oporavak. Ovaj set riječi služi za otključavanje cjelokupnog vašeg novčanika i njega nikada ni u kojem slučaju ne smijete s nikim podjeliti. Isto tako, dužni ste ovaj set riječi pohraniti na sigurno i vama lako dostupno mjesto da u slučaju potrebe isti možete upotrijebiti. Ako itko dođe u posjed ovog seta riječi bez problema može isprazniti vaš bitcoin novčanik.

Što je pristupna fraza

Pristupna fraza, passphrase ili zaporka, često je poznata kao dodatna 13. ili 25. riječ u setu od 12 ili 24 riječi koje se inače zapisuju kod inicijalizacije novog bitcoin novčanika. To je korisnički definirana dopunska riječ ili izraz namijenjen za jačanje sigurnosti. Da bi pristupio vašem novčaniku napadaču je potrebna i ta vaša dodatna riječ uz cjelokupnu frazu od 12 ili 24 riječi koje ste zapisali. Tu jednu dodatnu riječ nikada ne držite u blizini ili zajedno sa vašom frazom za oporavak od 12 ili 24 riječi.

Što je privatni ključ

Privatni ključ predstavlja dokaz da entitet koji ga posjeduje ima ovlaštenje za trošenje bitcoina s odgovarajuće bitcoin adrese. Privatni ključ kreira se iz vaše pristupne fraze. Za svaku adresu koja je otvorena u vašem novčaniku generira se privatni ključ. Danas, velika većina korisnika bitcoina nikada se neće izravno koristiti s privatnim ključem; umjesto toga, softver novčanika to odrađuje automatski za vas prilikom korištenja.

Što je javni ključ

Javni ključ za bitcoin je isto ono što je IBAN za vaš bankovni račun. To je bitcoin adresa na koju možete primati novac na blockchainu odnosno primati bitcoin na vašu bitcoin adresu.

Što je prošireni javni ključ

O proširenom javnom ključu ili Xpub možete razmišljati kao o glavnom ključu vašeg bitcoin novčanika. Isto kao i kod privatnih ključeva ili fraza za oporavak ovaj ključ nitko osim vas ne smije znati. Pomoću Xpub ključa moguće je generirati i vidjeti svaku adresu koja je prethodno generirana u vašem novčaniku. Ypub i Zpub su Xpub varijacije koje zapravo imaju istu funkciju.

Koji bitcoin novčanik je najbolji za vaše potrebe

Potpunu kontrolu nad svojim bitcoinom imate korištenjem hardverskih novčanika. Ali s tom potpunom kontrolom dolazi i potpuna individualna (vaša) odgovornost. Vi i samo vi ste odgovorni za sigurnost vašeg bitcoina. Vi sami morate osigurati fizičku zaštitu vašeg bitcoin novčanika kako ga ne biste izgubili ili da vam ne bude ukraden. Isto tako, morate zapamtiti lozinku vašeg bitcoin novčanika kako bi mogli pristupiti svojem bitcoinu.

S druge pak strane, čuvanje bitcoina na raznim bitcoin mjenjačnicama je mnogo jednostavnije ali morate biti svjesni da u tom slučaju ne posjedujete privatne ključeve koji vam garantiraju da sa svojim bitcoinom možete raditi što god želite, kada god to želite i u odnosu s kim god to želite.

Mjenjačnice koliko god velike bile ipak mogu biti hakirane. Najpoznatiji primjer takvog slučaja datira još iz 2014. godine kada je tada najveća mjenjačnica Mt.Gox napadnuta te je ukradeno oko 850.000 bitcoina. Dan danas velika većina tog ukradenog bitcoina još uvijek nije pronađena niti vraćena vlasnicima.

Danas je sigurnost na velikim mjenjačnicama znatno veća. Tvrtke kao što su Binance, Coinbase, Kraken itd., na primjer, drže veliku većinu svojih Bitcoina u tzv. cold storage novčanicima koji nisu povezani na Internet te su tako zaštićeni od cyber napada. Bez obzira na sve moguće oblike zaštite, mjenjačnice su uvijek izložene velikoj količini pokušaja upada u njihove sustave.

Idealan odabir novčanika ovisi od pojedinca do pojedinca. Radi se o preferencijama svakog ponaosob a faktori koji na to utječu mogu biti npr. iznos bitcoina koji se želi spremiti ili koliko brzo i jednostavno se tom bitcoinu želi moći pristupati. Slično kao i kod bilo koje druge vrste valuta, manje količine bitcoina možete držati u manje sigurnom novčaniku (u novčanicima na računalu ili mobitelu) do kojeg je jednostavno doći za svakodnevnu upotrebu, dok veće količine bitcoina svakako trebate držite skrivene na sigurnijem mjestu u hardverskim novčanicima tipa Ledger ili Trezor. Isto tako, ukoliko posjedujete veće količine bitcoina uputno ga je držati na više hardverskih novčanika koji se nikada ne bi trebali nalaziti na istom mjestu.

Hardverski novčanici

Postoje mnoge različite opcije za pohranu bitcoina, svaka sa svojim prednostima i nedostacima i po kojima se međusobno razlikuju. Kako biste spriječili krađu ili gubitak, ključno je da ste svoj bitcoin sigurno pohranili. Ako se dovedete u situaciju da je bitcoin izgubljen ili ukraden, velika je vjerojatnost da ga više nikada nećete pronaći i da je izgubljen trajno i nenadoknadivo. Iz tog razloga, trebali biste paziti da uvijek pohranite svoj bitcoin na sigurno. Najsigurnija opcija pohrane bitcoina je na hardverske (offline) novčanike.

Hardverski novčanici fizički su uređaji koji sliče najobičnijim USB stickovima a koji vam omogućuju sigurnu pohranu Bitcoina na njih. Da biste bitcoin poslali na svoj hardverski novčanik morate ga baš popust USB sticka spojiti na računalo. Istovremeno je potrebno instalirati i pokrenuti nativni programski paket koji ide uz novčanik te u njemu izvršiti sve potrebne operacije za prijenos bitcoina u vaš novčanik sa recimo online mjenjačnice na kojoj ste prethodno bitcoin kupili. Nakon prijenosa bitcoina u vaš hardverski novčanik, novčanik je potrebno pospremiti na sigurno. Hardverski novčanici zaštićeni su lozinkom, pa čak i ako je vaš hardverski novčanik izgubljen ili ukraden, netko i dalje treba lozinku za pristup vašem bitcoinu. Imajte na umu da svoju lozinku ne smijete držati zajedno sa novčanikom kao što npr. neki ljudi u svojim normalnim novčanicima drže pinove za kartice koje se nalaze u istom tom novčaniku. Ne moram vam objašnjavati koliko je to neodgovorno ponašanje.

Primjeri hardverskih novčanika:

Ledger

Ledger je vjerojatno najpoznatiji hardverski novčanik na tržištu. Ledger novčanici imaju visoku reputaciju za sigurnost i pouzdanost pohranjivanja bitcoina. Osim toga, izrađeni su od čvrstih materijala poput nehrđajućeg čelika, što povećava njihovu otpornost na oštećenja tokom vremena. Ovu dodatnu karakteristiku mnogi vide kao veliku prednost nad ostalim novčanicima.

!!VAŽNO!!

Prvi put kada koristite Ledger novčanik, biti će vam prikazana fraza za oporavak koju morate zapisati na papir koji je priložen u pakiranju samog novčanika. Ako izgubite svoj Ledger novčanik ili ako se jednostavno pokvari, korištenjem fraze za oporavak možete povratiti svoj bitcoin novčanik na novom uređaju.

!!POSEBNO VAŽNO!!

Svoj Ledger novčanik uvijek kupujte direktno od proizvođača ili od ovlaštenih distributera. Ako kupujete od nepoznatih trgovaca ili pojedinaca nemate garanciju da novčanik nije prethodno kompromitiran. Događali su se slučajevi da su ljudi novčanike kupovali preko ebay platforme. Novčanici su im dostavljeni na kućnu adresu ali su ti novčanici već u samom pakiranju imali ispunjene kartice sa frazom za oporavak. Poruka koju su novi vlasnici novčanika od prodavatelja dobili da su oni to već za vas napravili kako bi vam maksimalno olakšali upotrebu. Neiskusni korisnici su im na tome bili jako zahvali i nisu znali da ako netko drugi već zna tu frazu za oporavak da isto tako može pristupiti njihovom bitcoinu. Naravno, ti korisnici ostali su bez bitcoina koji su stavili na tako kompromitiran uređaj. Dakle, kada Ledger uređaj stigne na vašu adresu mora biti tvornički zatvoren. Kartica za zapis fraze za oporavak mora biti prazna i Ledger uređaj kada ga prvi put spojite na računalo mora vas provesti kroz proces generiranja fraze za oporavak koja se sastoji od 12 ili 24 riječi koje morate zapisati na karticu koja je s uređajem stigla.

Ledger ima više različitih uređaja a to su Ledger Nano S, Ledger Nano S Plus i Ledger Nano X. Detalje o svakom uređaju posebno i narudžbu možete napraviti klikom na naziv svakog od uređaja.

Trezor

Trezor novčanik je također veoma popularan hardverski novčanik vlasnicima bitcoina. Trezor novčanik nudi korisničko sučelje koje je jednostavno za korištenje te također ima visoku razinu sigurnosti i reputaciju na tržištu. Osim toga, Trezor ima izvrsnu podršku korisnicima, što je ključno s obzirom na to da mnogi kupci koji kupuju Trezor novčanike nikada prije nisu koristili hardverski novčanik pa im je za prvu upotrebu potrebna pomoć.

Kao i kod Ledger novčanika na početku korištenja morati će te zapisati frazu za oporavak koja se sastoji od 12 ili 24 riječi. U slučaju da izgubite ili oštetite svoj Trezor novčanik, ovu frazu za oporavak možete upotrijebiti za dohvat vašeg bitcoina na novom uređaju. Nakon što Trezor uređaj baš kao i Leger odspojite sa računala znači da putem interneta njemu više nitko ne može pristupiti. Kao i kod Ledger uređaja, Trezor morate pospremiti na sigurno mjesto kojem vi u svakom trenutku imate pristup.

Novčanici na računalu ili mobitelu

Novčanik koji kao aplikaciju možete instalirati na vašem računalu zove se još i desktop wallet ili desktop novčanik. Desktop novčanici općenito dolaze s više funkcionalnosti od mobilnih novčanika, ali mogu biti i kompliciraniji. Budući da su računala povezana na internet i podložna su zlonamjernom ili malicioznom softveru, trebate biti jako oprezni sa softverom koji instalirate.

Mobilni novčanik je onaj koji radi na vašem mobilnom telefonu. Ti novčanici omogućuju brz pristup vašem bitcoinu, ali isto tako nose sa sobom veliki rizik. Ako izgubite ili razbijete telefon, možete izgubiti i svoj bitcoin. Ako se to i desi to ne bi trebao biti problem pod uvjetom da je vaša „seed fraza“ sigurno pohranjena tako da možete svoj novčanik aktivirati na drugom uređaju.

Novčanici kojima upravljaju treće strane

Novčanici kod trećih strana su novčanici kod kojih vi ne kontrolirate privatne ključeve. Ovakvi novčanici često mogu olakšati potencijalne složenosti koje dolaze sa korištenjem bitcoin novčanika, ali to dolazi s rizikom da vi nemate kontrolu nad vašim privatnim ključevima pa tako ni nad vašim bitcoinom. Ovakvim novčanicima uglavnom upravljaju burze i korisnicima se savjetuje da na njima ne drže velike količine bitcoina. Neke od najpoznatijih online mjenjačnica su Binance, FTX (tokom 2022. godine ispostavilo se da je ova mjenjačnica jedna od največih prijevara u povijesti kripta), Coinbase, Kraken, KuCoin, Gemini, Gate.io, Bitfinex, Bitstamp, Bybit itd. Kao što je već rečeno ti novčanici su jednostavniji i praktičniji za korištenje ali vi ne posjedujete vaše privatne ključeve.

Često ove online mjenjačnice osiguravaju svoje kripto novčanike metodama kao što su identifikacija s 2 ili 3 faktorskom autentifikacijom i vremenskim odmakom za transakcije. Na primjer, online mjenjačnica Coinbase ima sigurnosnu opciju koja se zove “pohrana u trezoru” koja vam omogućuje prijenos Bitcoina s običnog novčanika u novčanik koji ima razdoblje čekanja od 48 sati za povlačenje vašeg bitcoina i zahtijeva provjeru telefonskim putem i sa dvije različite email adrese. Dodatne usluge ovog tipa značajno pridonose povećanju sigurnosti.

Skrbnička rješenja

Skrbnička rješenja su obično namijenjena institucijama ili pojedincima koji žele zaštititi velike količine kripto valuta. Takvi novčanici obično su osigurani od gubitka ili krađe do određenih iznosa. Danas postoje brojne usluge čuvanja bitcoina visoke razine sigurnosti za institucionalne ulagače. Tvrtke kao što su Coinbase, Gemini, Fidelity ili BitGo nude skrbništvo nad Bitcoinom. Ukoliko ste ste pojedinac s velikom neto vrijednošću u bitcoinu ili ako predstavljate instituciju, tada bi jedno od ovakvih rješenja mogla biti prava opcija za vas.

Novčanik s više potpisa

Novčanik koji treba više od jednog privatnog ključa za potpisivanje transakcije poznat je kao novčanik s više potpisa ili multi-sig wallet. Prilikom izrade novčanika, korisnik može odabrati hoće li upotrijebiti 2 od moguća 3 ključa za potpisivanje ili 15 od mogućih 20. Iako je multi-sig novčanik puno kompliciraniji za kreirati od novčanika sa samo jednim privatnim ključem on je zato sigurniji od novčanika sa samo jednim privatnim ključem.

Novčanici samo za pregled

Vaš prošireni javni ključ (Xpub), koji vam omogućuje pregled stanja novčanika, koristi se za izradu novčanika koji omogućavaju samo uvid u stanje novčanika (view only) bez mogućnosti potpisivanja transakcija odnosno slanja bitcoina iz njega. Ovakvi novčanici ne mogu se koristiti niti za kupnju jer nemaju privatne ključeve.

Transakcijske naknade

Ovisno o brzini kojom želite da se transakcija obavi imate mogućnost da odaberete visinu transakcijske naknade. Što je naknada viša vaša transakcija će prije biti obrađena. Uz to morate biti svjesni da vrijeme obrade transakcije ovisi i o zauzetosti mreže u datom trenutku. Prilikom transakcije u vašem novčaniku vidjet će te procjenu kolika je transakcijska naknada te će te imati mogućnost povećati ili smanjiti taj parametar.

Što je to QR kod

Podaci o adresama i iznosima vizualno mogu biti predstavljeni i putem QR koda. QR kodovi se najčešće koriste kako bi se dugačke i komplicirane za zapamtiti bitcoin adrese jednostavno mogle skenirati vašim mobilnim uređajem. Na ovaj način eliminira se potreba za ručnim upisivanjem adrese, što može rezultirati pogreškama prilikom prepisivanja i slanjem bitcoina na nepostojeću adresu. Ukoliko se to desi nažalost vaš bitcoin je nepovratno izgubljen.

Uobičajene pogreške

Bitcoin alternative

Odmah na početku moramo reći da bitcoin nema alternativu. Alternativne kripto valute kojih danas ima gotovo 20.000 u više od 99.99% slučajeva su čiste prevare koje se temelje na privlačenju korisnika putem različitih marketinških trikova i buzzworda poput izraza „decentralizirano financiranje“. Korištenjem razno raznih aplikacija koje nude velike prinose možda zvuči primamljivo ali morate biti svjesni da takvi prinosi nisu komercijalno održivi i da će zasigurno doći trenutak kada će se ti sistemi urušiti. Ukoliko ste svoj bitcoin deponirali na platforme ovog tipa savjetujem vas da ga što prije povučete na svoj novčanik za koji posjedujete svoje privatne ključeve.

Kupnja bitcoina na centraliziranim mjenjačnicama

Kupnja KYC (Know-Your-Customer) bitcoina na centraliziranim mjenjačnicama (CEX) brz je i jednostavan način. No ipak morate biti svjesni kompromisa i posljedica koje iz toga proizlaze. Kako bi ste se uspješno registrirali na centraliziranim mjenjačnicama minimalno što će te morati napraviti je ostaviti vaš osobni dokument sa slikom. Na temelju toga, budući da je bitcoin transakcije moguće pratiti uvijek vas se može povezati sa adresom na kojoj je vaš bitcoin pohranjen. Isto tako, sve vaše buduće transakcije mogu biti praćene. Ukoliko je ovo nešto što vam nije o značaja bitcoin slobodno kupite na online mjenjačnicama ali ga svakako prebacite na vaš novčanik tako da ga ne ostavljate u novčaniku mjenjačnice.

Ne istražiti druge opcije kupnje

Koja alternativna rješenja na tržištu postoje ako vam se ne sviđa prizvuk kupovine bitcoina na centraliziranim mjenjačnicama gdje ste dužni ostaviti svoje podatke. Iako postoje peer-to-peer platforme za razmjenu kao što su Bisq i HodlHodl koje koriste escrow usluge kako bi vam omogućile stjecanje bitcoina od bilo koga u cijelom svijetu, one obično nisu tako jednostavne za korištenje kao KYC alternative. Najjednostavniji način za početak je kupnja od prijatelja, osoba od povjerenja ili pak članova obitelji. Mnogi korisnici su odavno shvatili koliko je anonimnost zapravo važna. Ako se raspitate malo oko sebe zasigurno će te naići na nekoga tko bitcoin već posjeduje a za koga to možda nikada ne bi rekli. To su ljudi koji ne oglašavaju na sva zvona da posjeduju bitcoin i to bi zapravo svatko trebao tako raditi. Raspitajte se oko sebe, netko sigurno ima bitcoina koji je spreman prodati.

Druga dobra alternativa za anonimno stjecanje bitcoina je rudarenje ali to je zasebna i tehnološki malo zahtjevnija edukacija o kojoj će biti govora na ovoj stranici. Svakako morate biti upoznati i s poreznim aspektom ovakvog načina stjecanja bitcoina.

Ne imati svoj vlastiti „node“

Korištenje vlastitog noda vam daje sigurnost da su informacije prikazane u vašem novčaniku točne i u skladu s “Bitcoin propisima” vašeg čvora. Jednostavno rečeno, ako ne koristite vlastiti node, znači da koristite nečiji tuđi bez obzira da li znate tu osobu ili ne. Bitcoin tako jednostavno funkcionira. Korištenjem vlastitog noda ne morate se oslanjati ni na koga drugoga za provođenje transakcija kada imate novčanik povezan s vlastitim nodom, što daje ogromne prednosti u pogledu privatnosti.

Ostavljati bitcoin na mjenjačnicama

Nakon što ste kupili bitcoin na nekoj od mjenjačnica (KYC) i ostavili sve svoje osobne podatke, ostavili ste ga na burzi jer niste znali kako se koristit bitcoin novčanik ili kako se bitcoin sa mjenjačnice šalje u vaš novčanik. Morate biti svjesni da vi ne posjedujete privatne ključeve novčanika u kojima se bitcoin nalazi na mjenjačnicama na kojoj ste ga kupili bez obzira što ga vidite nakon što ste se na mjenjačnicu ulogirali. Vaš korisnički račun na mjenjačnici nije isto što i bitcoin novčanik. Bitcoin koji vam stoji na mjenjačnici što prije pospremite u novčanik za koji vi i samo vi posjedujete privatne ključeve. Ne dopustite da vam se dogodi situacija u kojoj će neka mjenjačnica biti meta hakerskog napada i sa koje je ukraden bitcoin među kojima se nalazi i vaš. Bilo je mnogo ovakvih slučajeva posljednjih godina. Isto tako, nisu ni sve mjenjačnice u potpunosti legitimne te je bilo slučajeva da su vlasnici istih jednostavno nestali i sa sobom uzeli ogromne količine tuđeg novca (bitcoina i ostalih kripto valuta).

Također, u zadnje vrijeme otkako je tržište kripto valuta dosta potonulo (isto kao i sva ostala tržišta) došlo je do situacija da su pojedine firme (mjenjačnice ali i firme koje se bave pružanjem drugačijih usluga na kripto tržištu) zbog krize koja ih je pogodila jednostavno postale insolventne. Jedna od stvari koje su prvo napravile bilo je to da su onemogućili korisnicima da sa tih platformi povuku svoja sredstva. Najznačajniji primjeri ovakvih događaja su vezani za Celsius i BlockFi. Nemojte se dovoditi u ovakve situacije i obavezno svoj bitcoin nakon kupovine prebacite na svoj novčanik u kojem vi upravljate sa svojim privatnim ključevima.

Slati nekome svoje privatne ključeve

Prevaranti se često predstavljaju kao članovi bitcoin zajednice kako bi ponudili podršku nekome tko možda traži pomoć putem chat aplikacija kao što su Telegram, Discord i sl. Te osobe se će vam najčešće poslati linkove na kojima trebate upisati svoje privatne ključeve ili frazu za oporavak kako bi oni tobože provjerili da ste vi stvarno vlasnik tog novčanika i kako bi vam onda mogli pružiti pomoć. To je naravno jedna velika laž. Nikada, ali baš nikada, nikome (ni policiji, ni poreznim vlastima, ni državnim institucijama) ne dajte svoje privatne ključeve ili frazu za oporavak a posebno ne online.

Nesigurna pohrana vaše „fraze za oporavak“

Ključ do vašeg bitcoina je vaša fraza za oporavak i svatko tko joj ima pristup ima i pristup vašem bitcoinu. Treba ju čuvati na sigurnom mjestu, ali pripazite da ne bude „toliko sigurna“ da i vi zaboravite gdje je ili kako glasi. Jedna veoma loša ideja je držati ju na računalu ili u mobitelu. Vjerojatno najsigurnija metoda je da ju „jednostavno“ zapamtite i da ne postoji druga kopija. Ali naravno morate biti sigurni da će te ju moći reproducirati kada za to dođe vrijeme.

Slanje bitcoina na netočnu adresu

Ovih dana sve je teže to učiniti jer novčanici sada imaju značajke otkrivanja pogrešaka i QR kodove koji se mogu skenirati kamerom na vašem mobilnom telefonu. Kada nekome šaljete bitcoin, uvijek je najbolje koristiti QR kodove ili copy/paste bitcoin adrese jer dugi nizovi brojeva i slova nisu jednostavni za prepisivanje i lako može doći do pogreške. Prije finalnog slanja uputno je još jednom ipak provjeriti adresu prije slanja.

Pretjerana euforija

Što više budete učili o bitcoinu i kako budete sve dublje i dublje shvaćali što je to zapravo bitcoin i kako funkcionira nemoguće je da vas neće uhvatiti euforija. Još ako vrijeme počnete provoditi recimo na Twitteru i YouTube-u gdje se vjerojatno najviše sadržaja generira o bitcoinu možete doći u iskušenje da na bitcoin potrošite više novca nego si to zaista i možete priuštiti. Bitcoin je još uvijek mlada i veoma cjenovno osjetljiva klasa imovine. Nemojte se dovesti u situaciju da kada dođe do većih padova cijene da razmišljate hoćete li sutra imati za stanarinu ili još gore za osnovne životne namirnice. Ne ulažite u bitcoin novac koji si ne možete priuštiti da ga u potpunosti izgubite. Ovo vrijedi za sve klase imovine pa tako i za bitcoin.

Trgovanje na burzama

Trgovanje bitcoinom na burzama može biti jako primamljiva stvar ako znate da dnevne fluktuacije cijene bitcoina znaju biti i 20%. Kripto tržište je još uvijek mlado i neregulirano pa tako i mjenjačnice na kojima se trguje. Vi kao mali igrač nemate nikakve šanse protiv velikih igrača koji još uvijek sa relativno „malo novca“ mogu manipulirati cijenom bitcoina a to znači da će te vi biti „likvidirani“. Ostavite trgovanje nekome drugome a vi online mjenjačnice koristite samo za kupovanje bitcoina i slanje istoga na svoj privatni novčanik.

Ne radite od sebe metu

Bitcoin živi na internetu koji je, slično kao i stvarni svijet, pun prevaranata koji su spremni otići daleko kako bi se domogli vašeg bitcoina. Razgovorom o posjedovanju bitcoina na internetu ili u stvarnom svijetu doslovno stavljate metu na vaša leđa za lopove ili prevarante. Uobičajeni pristup za ljude koji komuniciraju online s bitcoin zajednicom je stvaranje online persone koja je potpuno odvojena od vašeg stvarnog identiteta.

Ne koristiti 2FA

Danas je vaša email adresa povezana s računom za sve što radite online. Prevaranti relativno jednostavno mogu dobiti pristup vašim privatnim podacima ako ne vodite dovoljnu pažnju oko zaštite te vaše email adrese. Dodatni sigurnosni mehanizam, dvostruka autentifikacija ili 2FA, štiti vas od nepoželjnih upada u korisničke račune. Najpoznatije dvije 2FA aplikacije su Google Authenticator i Authy koje možete preuzeti putem vašeg mobilnog telefona kao i svaku drugu aplikaciju. Svakako koristite ove mogućnosti dodatne zaštite za sve vaše online korisničke račune i izbjegavajte oblik ovakve 2FA autentifikacije putem SMS poruka.

Ne tražiti pomoć ako nešto ne znate

Bitcoin zajednica je danas izrazito rasprostranjena i korisna. Postoje stotine različitih telegram grupa, GitHub ili reddit stranica, profila na Twitteru koji su voljni pomoći u svako doba. Ako imate bilo kakvo pitanje slobodno se i nama obratite i postavite pitanje. Zapamtite, ako niste sigurni, pitajte.

Mitovi o bitcoinu

Bitcoin nema intrinzičnu vrijednost

Kao i svakog novca, vrijednost bitcoina proizlazi iz kredibiliteta njegovih monetarnih svojstava. Vrijednost bitcoina proizlazi iz toga što se njegova rijetkost, njegov postojeći i konačan broj lagano i neovisno može provjeriti u bilo kojem trenutku. Distribuirano rudarenje bitcoina i mehanizam konsenzusa iza kojeg stoje stotine milijuna dolara vrijedne računalne opreme koja osigurava mrežu 24/7/365 čine ga iznimno vrijednim. Budući da se danas svatko s internetskom vezom može uključiti u mrežu, bitcoin je jedini pravi oblik novca. Bitcoin ne cenzurira niti diskriminira za razliku od svih ostalih oblika novca u optjecaju.

Bitcoin je anoniman

Ovo nije istina. Na razini Bitcoin mreže novčanik ili adresa nisu izravno povezani s identitetom neke osobe u stvarnom svijetu. Kao rezultat toga, tvrtke koje se bave analizom podataka na mreži mogu pratiti transakcije s adrese na adresu ali ne znaju tko je vlasnik tih adresa. Kupovinom bitcoina na centraliziranim mjenjačnicama gdje ste dužni ostaviti osobne podatke omogućavate da vas se prati odnosno da se adrese koje ste koristili na mjenjačnicama budu direktno povezane s vašim imenom i prezimenom. Razmislite da li ovo želite prije nego bitcoin kupite na centraliziranim mjenjačnicama.

Bitcoin programski kod jednostavno može biti izmijenjen

Ovo također nije istina. Bitcoin je poznat po tome da je za svaku i najmanju promjenu u programskom kodu potrebno jako puno vremena. To je ujedno i stavka zbog koje je i dosta kritiziran ali samo od strane ljudi koji bitcoin ne razumiju dovoljno ili koji imaju vlastite osobne interese u želji za promjenom bitcoin koda. Ne učestale promjene programskog koda bitcoina su jedan od temeljnih postulata na kojima se gradi sigurnost bitcoina odnosno Bitcoin mreže. Sve značajne izmjene Bitcoin koda moraju proći rigorozan postupak recenzije. Proces postaje znatno sporiji i rigorozniji ako predložena izmjena koda može utjecati na kompatibilnost sa prethodnim verzijama softvera (što znači da raniji softver možda nije kompatibilan).

Bitcoin može biti kopiran

Da, to je istina. Bitcoin se može kopirati i tisuće ljudi su to već napravili na razini mreže. Doslovno gdje god da se okrenete imate neku kripto valutu koja je nastala kopiranjem Bitcoin programskog koda koji je samo „malo“ u nekim dijelovima izmijenjen kako bi se taj „novi“ Bitcoin „poboljšao“ u odnosu na jedan jedini i pravi Bitcoin. Ovakva “poboljšanja” gotovo uvijek uključuju značajne kompromise koji su u većini slučajeva iz domene sigurnosti mreže na kojoj te „poboljšane“ verzije Bitcoina egzistiraju. Svi takvi pokušaji kopiranja su najobičniji klonovi koji obično imaju tzv. nepošteno pokretanje nove kripto valute koje se uvijek radi samo u korist onoga tko takvu novu kripto valutu pokreće.

Ti projekti su izrazito centralizirani i često je sva upravljačka moć oko takvih projekata u rukama samo nekoliko ljudi. Prethodno je već spomenuto da bitcoin nema alternativu i to je tako. Preporuka je da se držite samo pravog bitcoina i ne petljate se sa lažnim projektima koji ga potkopavaju razno raznim marketinškim trikovima. Bitcoin funkcionira već 13 godina bez ijednog sigurnosnog propusta na razini mreže odnosno programskog koda. Razmislite o ovome prije nego počnete trošiti vrijeme na neki od tisuća besmislenih bitcoin klonova.

Nema dovoljno bitcoina za sve na svijetu

Samo 21 milijun bitcoina ikada može postojati. Jedan bitcoin podijeljen je na 100 milijuna satoshija. To znači da će ukupno u optjecaju biti 2,1 kvadrilijun satoshija (2.100.000.000.000.000) dostupno za transakcije na Bitcoin mreži. Ako recimo broj stanovnika na zemlji zaokružimo na 8 milijardi, svakom stanovniku pripalo bi 262.500 satoshija. Ima li dovoljno bitcoina za sve ljude na zemlji? Ne nasjedajte na ovakva pitanja neznalica.

Transakcijske naknade će bitcoin u budućnosti učiniti neupotrebljivim

Bitcoin mreža ima vrlo učinkovito tržište naknada. Tokom povijesti bilo je nekih kratkotrajnih eksponencijalnih skokova broja transakcija na mreži što je uzrokovalo porast naknada. Prosječna transakcijska naknada u dolarima u proteklih 12 mjeseci iznosila je oko 80 centi. Transakcijske naknade na mreži potrebno je razlikovati od transakcijskih naknada koje će vam naplatiti online mjenjačnice i drugi servisi kada ih koristite za povlačenje bitcoina u vlastiti novčanik. Naknade za bitcoin transakcije će zasigurno tokom vremena porasti ali zasigurno nikada neće biti na razini naknada koje vam naplaćuju ako si naprimjer novac sa računa u jednoj zemlji želite poslati na račun u drugoj zemlji. Ili npr. ako neki radnik u zapadnoj Europi svojoj obitelji u istočnoj Europi želi poslati novac. Pitajte ih koliku naknadu im naplaćuje banka na takve transfere ili neki od servisa poput Western Uniona.

Ovo se odnosi na transakcije koje se dešavaju baš na bitcoin mreži. Danas je već u punoj primjeni Lightning mreža koja je rješenje za skaliranje na bitcoinu i koja omogućuje transakcije s naknadama koje iznose samo nekoliko satoshija. Više o Lightningu možete pročitati ovdje.

Rudari kontroliraju bitcoin

Iako je istina da su rudari ključni za funkcioniranje Bitcoin mreže, nije istina da oni kontroliraju mrežu. Mreža kako bi nastavila sa funkcioniranjem treba samo malo više od 50% rudara da se ponašaju kao „pošteni igrači“. Rudari su financijski motivirani da budu pošteni igrači na mreži. U manje vjerojatnom ili besmislenom scenariju zlonamjerni rudari koji bi preuzeli kontrolu nad mrežom, održavanje iste procjenjuje se da bi ih koštalo između 300-500 tisuća dolara po satu. Osim što je to veoma skupa operacija, ako bi i uspjeli, cijena bitcoina bi u tom slučaju na tržištu pala, pa tako svaki novi bitcoin koji bi nepošteni rudari dobili zapravo ne bi pokrio troškove koje moraju uložiti za napad na Bitcoin mrežu.

Rudari će prestati s rudarenjem kada subvencije za blokove padnu

Budući da će se subvencije za nove blokove u budućnosti smanjiti, nitko sa sigurnošću ne može reći da će do toga zaista i doći. Međutim, većinsko i zajedničko mišljenje je da će rudari i dalje biti plaćeni za svoj rad na obradi transakcija i zaštiti mreže. Naknade će se povećavati kako se blok subvencije budu smanjivale. Kada do toga i dođe, vjerojatnost široke rasprostranjenosti korištenja Lightning rješenja za skaliranje je velika jer to tehnološko rješenje i prihvaćanje od strane korisnika doslovno napreduje brzinom svjetlosti. Zbog mrežne “prilagodbe kompleksnosti izračuna”, čak i da neki rudari prestanu rudariti, mreža bi i dalje normalno funkcionirala jer je programskim kodom zacrtano stvaranje novih blokova svakih 10 minuta.

Rudarenje je štetno za okoliš

Istina je da proces rudarenja temeljen na proof of work konceptu koristi značajne količine energije ali isto tako istina je da je velika većina te energije dolazi iz obnovljivih izvora. Bitcoin rudari unaprjeđuju tehnologiju „hvatanja“ energije iz izvora koji bi inače bili bačeni a to se prvenstveno odnosi na spaljivanje prirodnih plinova prilikom vađenja nafte. Bitcoin koristi energije samo onoliko koliko je potrebno da zadovolji potražnju tržišta. Sva energija koja se potroši, potroši se na očuvanje najsigurnije računalne mreže na svijetu. Trošenje energije povezano s bitcoinom uvijek se namjerno predstavlja u negativnom kontekstu koji je sponzoriran uvijek iz istih izvora. Taj izvor su uvijek pojedinci i organizacije povezane sa lažnom premisom djelovanja u smislu zaštite okoliša.

Bitcoin je jako spor

Ako bi ste koristili bitcoin za recimo svakodnevno plaćanje u trgovinama i da pri tome trebate na blagajni čekati desetak minuta da transakcija bude verificirana to naravno nije prihvatljiva solucija za nikoga. Ali ovaj problem već ima svoje rješenje i zove se Lightning mreža koja se unaprjeđuje svakodnevno. Možda još uvijek nije na razini mnogobrojnih CashApp aplikacija ali to i nije više tako daleko kada će biti. Ako pak npr. želite veću količinu novca (recimo 500.000 kuna) prebaciti sa svog bitcoin novčanika na tuđi bitcoin novčanik pri tome ne trebate nekoga u banci da vam prebroji krvna zrnca, udari pečat i naplati pečat tintu par stotina ili tisuća kuna. U tom slučaju, čekanje desetak minuta da se transakcija na mreži verificira i nije tako loša opcija.

Bitcoin je pretežak za korištenje

Težina korištenja je vrlo individualna i subjektivna kategorija. Ipak, danas je jednostavnije prisloniti karticu na POS terminalu u trgovini nego izvaditi telefon, skenirati QR kod i čekati potvrdu transakcije. Ali isto tako, ta dva dodatne koraka potrebna za provođenje bitcoin transakcije mala su cijena za prednosti koje mreža pruža. Brojni bitcoin programeri danonoćno rade kako bi poboljšali svakodnevno korisničko iskustvo korištenja bitcoin rješenja a da pri tome često za svoj rad nisu niti plaćeni. Kako i svaka druga tehnologija, potrebno je vrijeme kako bi se tehnologija razvila i usavršila kako bi postala praktična za korištenje u svakodnevnom životu.

60/40 portfolio je dugo važio za idealan izbor nekome ko ima umerenu sklonost ka riziku, a nema vremena da prati berzu. Dakle, ubaciš 60% u akcije, 40% u obveznice i pustiš vreme da radi svoje.

Malo sam se igrao sa brojkama i računao šta bi bilo da je neko u taj portfolio ubacio malo Bitkoina. Period koji je obrađen je januar 2014 - januar 2024. Ovde napominjem da nikako nisam radio "cherry picking", to jest nisam birao period u kome se Bitkoin pokazao u najboljem mogućem svetlu. Maltene sam uradio suprotno. Da sam izabrao bilo koji januar pre 2014-te, prinosi na BTC bi bili neuporedivo veći. Čak i da sam izabrao januar 2015-te ili 2016-te, takođe bi prinosi bili veći jer je cena tada bila niža nego u januaru 2014-te. Izbor datuma je bio posledica želje da zaokružim jednu celu deceniju, period nakon kojeg su strpljivi investitori nagrađeni time što ne plaćaju porez na kapitalnu dobit.

Obradio sam 3 realna scenarija:

1. Klasičan 60/40 portfolio. Na uloženih $10.000 u januaru 2014. godine, 10 godina kasnije bismo imali tačno $17.434. Prosečan godišnji prinos je 5,72%.
2. 99% uloženo u 60/40 portfolio, 1% uloženo u Bitkoin. Na uloženih $10.000, imali bismo $22.505 ili 8,45% godišnje. Samo 1% u BTC, a skoro 3% veći godišnji prinos. (narandžasta linija)
3. 90% uloženo u 60/40 portfolio, 10% uloženo u Bitkoin. Sad već postaje zabavno... od $10.000 do $68.145, što bi bilo 21,16% godišnje - jače od proseka Vorena Bafeta. (zelena linija)

Uzeo sam u obzir i rizike i zamislio da je u ovom periodu cena Bitkoina polako padala i na kraju pala na 0. Dakle naredna 2 scenarija su hipotetička.

1. 99% uloženo u 60/40 portfolio, 1% uloženo u Bitkoin, Bitkoin propao. Investirano $10.000, dobijeno $17.259 ili 5.61% godišnje. Minimalni gubitak u odnosu na čist 60/40 portfolio iz prvog scenarija. Zbog toga se na grafiku vide 4 linije iako ih ima 5, toliko je mala razlika.
2. 90% uloženo u 60/40 portfolio, 10% uloženo u Bitkoin, Bitkoin propao. Investirano $10.000, dobijeno $15.690 ili 4.61% godišnje. To je ona donja. ljubičasta linija na grafikonu. Nije neki prinos, ali nije ni katastrofa.

Mogao sam da idem i sa preko 10%, naravno završili bismo na preko $100.000. Međutim, hteo sam da budem konzervativan i stvari gledam iz ugla investitora koji ipak ima nešto manji apetit ka riziku i nedovljno poznaje Bitkoin. Mogao sam i da uzmem drugačiji period. Na primer, za jan 2012 - jan 2022 bi narandžasta linija završila na preko milion dolara, a zelena na preko 10 miliona. Da, nije greška u računici... zaista biste za 10 godina, počev od januara 2012-te imali preko milion dolara da ste uložili ukupno $10.000, 99% u akcije i obveznice, a 1% u Bitkoin. Sa 90% u akcijama i obveznicama i 10% u Bitkoinu, već ste na 8 cifara.

Istorijske performanse nisu garancija budućih prinosa. Investiranje u Bitkoin je rizično. Ignorisanje Bitkoina je rizično. Svako bira svoj rizik. Ovo nije investicioni savet, ovo je prijateljski savet.

Du bist recht appetitlich oben anzuschauen, \ doch unten hin die Bestie macht mir Grauen. \ Johann Wolfgang von Goethe

Wie wenig bekömmlich sogenannte «Ultra-Processed Foods» wie Fertiggerichte, abgepackte Snacks oder Softdrinks sind, hat kürzlich eine neue Studie untersucht. Derweil kann Fleisch auch wegen des Einsatzes antimikrobieller Mittel in der Massentierhaltung ein Problem darstellen. Internationale Bemühungen, diesen Gebrauch zu reduzieren, um die Antibiotikaresistenz bei Menschen einzudämmen, sind nun möglicherweise gefährdet.

Leider ist Politik oft mindestens genauso unappetitlich und ungesund wie diverse Lebensmittel. Die «Corona-Zeit» und ihre Auswirkungen sind ein beredtes Beispiel. Der Thüringer Landtag diskutiert gerade den Entwurf eines «Coronamaßnahmen-Unrechtsbereinigungsgesetzes» und das kanadische Gesundheitsministerium versucht, tausende Entschädigungsanträge wegen Impfnebenwirkungen mit dem Budget von 75 Millionen Dollar unter einen Hut zu bekommen. In den USA soll die Zulassung von Covid-«Impfstoffen» überdacht werden, während man sich mit China um die Herkunft des Virus streitet.

Wo Corona-Verbrecher von Medien und Justiz gedeckt werden, verfolgt man Aufklärer und Aufdecker mit aller Härte. Der Anwalt und Mitbegründer des Corona-Ausschusses Reiner Fuellmich, der seit Oktober 2023 in Untersuchungshaft sitzt, wurde letzte Woche zu drei Jahren und neun Monaten verurteilt – wegen Veruntreuung. Am Mittwoch teilte der von vielen Impfschadensprozessen bekannte Anwalt Tobias Ulbrich mit, dass er vom Staatsschutz verfolgt wird und sich daher künftig nicht mehr öffentlich äußern werde.

Von der kommenden deutschen Bundesregierung aus Wählerbetrügern, Transatlantikern, Corona-Hardlinern und Russenhassern kann unmöglich eine Verbesserung erwartet werden. Nina Warken beispielsweise, die das Ressort Gesundheit übernehmen soll, diffamierte Maßnahmenkritiker als «Coronaleugner» und forderte eine Impfpflicht, da die wundersamen Injektionen angeblich «nachweislich helfen». Laut dem designierten Außenminister Johann Wadephul wird Russland «für uns immer der Feind» bleiben. Deswegen will er die Ukraine «nicht verlieren lassen» und sieht die Bevölkerung hinter sich, solange nicht deutsche Soldaten dort sterben könnten.

Eine wichtige Personalie ist auch die des künftigen Regierungssprechers. Wenngleich Hebestreit an Arroganz schwer zu überbieten sein wird, dürfte sich die Art der Kommunikation mit Stefan Kornelius in der Sache kaum ändern. Der Politikchef der Süddeutschen Zeitung «prägte den Meinungsjournalismus der SZ» und schrieb «in dieser Rolle auch für die Titel der Tamedia». Allerdings ist, anders als noch vor zehn Jahren, die Einbindung von Journalisten in Thinktanks wie die Deutsche Atlantische Gesellschaft (DAG) ja heute eher eine Empfehlung als ein Problem.

Ungesund ist definitiv auch die totale Digitalisierung, nicht nur im Gesundheitswesen. Lauterbachs Abschiedsgeschenk, die «abgesicherte» elektronische Patientenakte (ePA) ist völlig überraschenderweise direkt nach dem Bundesstart erneut gehackt worden. Norbert Häring kommentiert angesichts der Datenlecks, wer die ePA nicht abwähle, könne seine Gesundheitsdaten ebensogut auf Facebook posten.

Dass die staatlichen Kontrolleure so wenig auf freie Software und dezentrale Lösungen setzen, verdeutlicht die eigentlichen Intentionen hinter der Digitalisierungswut. Um Sicherheit und Souveränität geht es ihnen jedenfalls nicht – sonst gäbe es zum Beispiel mehr Unterstützung für Bitcoin und für Initiativen wie die der Spar-Supermärkte in der Schweiz.

The arrival of the coronavirus brought not only illness and death but also fear and panic. In such an environment of uncertainty, people have naturally stocked up on necessities, not knowing when things will return to normal.

Retail shelves have been cleared out, and even online suppliers like Amazon and Walmart are out of stock for some items. Independent sellers on these e-commerce platforms have had to fill the gap. With the huge increase in demand, they have found that their inventory has skyrocketed in value.

Many in need of these items (e.g. toilet paper, hand sanitizer and masks) balk at the new prices. They feel they are being taken advantage of in a time of need and call for intervention by the government to lower prices. The government has heeded that call, labeling the independent sellers as "price gougers" and threatening sanctions if they don't lower their prices. Amazon has suspended seller accounts and law enforcement at all levels have threatened to prosecute. Prices have dropped as a result and at first glance this seems like a victory for fair play. But, we will have to dig deeper to understand the unseen consequences of this intervention.

We must look at the economics of the situation, how supply and demand result in a price and how that price acts as a signal that goes out to everyone, informing them of underlying conditions in the economy and helping coordinate their actions.

It all started with a rise in demand. Given a fixed supply (e.g., the limited stock on shelves and in warehouses), an increase in demand inevitably leads to higher prices. Most people are familiar with this phenomenon, such as paying more for airline tickets during holidays or surge pricing for rides.

Higher prices discourage less critical uses of scarce resources. For example, you might not pay $1,000 for a plane ticket to visit your aunt if you can get one for $100 the following week, but someone else might pay that price to visit a dying relative. They value that plane seat more than you.

*** During the crisis, demand surged and their shelves emptied even though

However, retail outlets have not raised prices. They have kept them low, so the low-value uses of things like toilet paper, masks and hand sanitizer has continued. Often, this "use" just takes the form of hoarding. At everyday low prices, it makes sense to buy hundreds of rolls and bottles. You know you will use them eventually, so why not stock up? And, with all those extra supplies in the closet and basement, you don't need to change your behavior much. You don't have to ration your use.

At the low prices, these scarce resources got bought up faster and faster until there was simply none left. The reality of the situation became painfully clear to those who didn't panic and got to the store late: You have no toilet paper and you're not going to any time soon.

However, if prices had been allowed to rise, a number of effects would have taken place that would have coordinated the behavior of everyone so that valuable resources would not have been wasted or hoarded, and everyone could have had access to what they needed.

On the demand side, if prices had been allowed to rise, people would have begun to self-ration. You might leave those extra plies on the roll next time if you know they will cost ten times as much to replace. Or, you might choose to clean up a spill with a rag rather than disposable tissue. Most importantly, you won't hoard as much. That 50th bottle of hand sanitizer might just not be worth it at the new, high price. You'll leave it on the shelf for someone else who may have none.

On the supply side, higher prices would have incentivized people to offer up more of their stockpiles for sale. If you have a pallet full of toilet paper in your basement and all of the sudden they are worth $15 per roll, you might just list a few online. But, if it is illegal to do so, you probably won't.

Imagine you run a business installing insulation and have a few thousand respirator masks on hand for your employees. During a pandemic, it is much more important that people breathe filtered air than that insulation get installed, and that fact is reflected in higher prices. You will sell your extra masks at the higher price rather than store them for future insulation jobs, and the scarce resource will be put to its most important use.

Producers of hand sanitizer would go into overdrive if prices were allowed to rise. They would pay their employees overtime, hire new ones, and pay a premium for their supplies, making sure their raw materials don't go to less important uses.

These kinds of coordinated actions all across the economy would be impossible without real prices to guide them. How do you know if it makes sense to spend an extra $10k bringing a thousand masks to market unless you know you can get more than $10 per mask? If the price is kept artificially low, you simply can't do it. The money just isn't there.

These are the immediate effects of a price change, but incredibly, price changes also coordinate people's actions across space and time.

Across space, there are different supply and demand conditions in different places, and thus prices are not uniform. We know some places are real "hot spots" for the virus, while others are mostly unaffected. High demand in the hot spots leads to higher prices there, which attracts more of the resource to those areas. Boxes and boxes of essential items would pour in where they are needed most from where they are needed least, but only if prices were allowed to adjust freely.

This would be accomplished by individuals and businesses buying low in the unaffected areas, selling high in the hot spots and subtracting their labor and transportation costs from the difference. Producers of new supply would know exactly where it is most needed and ship to the high-demand, high-price areas first. The effect of these actions is to increase prices in the low demand areas and reduce them in the high demand areas. People in the low demand areas will start to self-ration more, reflecting the reality of their neighbors, and people in the hotspots will get some relief.

However, by artificially suppressing prices in the hot spot, people there will simply buy up the available supply and run out, and it will be cost prohibitive to bring in new supply from low-demand areas.

Prices coordinate economic actions across time as well. Just as entrepreneurs and businesses can profit by transporting scarce necessities from low-demand to high-demand areas, they can also profit by buying in low-demand times and storing their merchandise for when it is needed most.

Just as allowing prices to freely adjust in one area relative to another will send all the right signals for the optimal use of a scarce resource, allowing prices to freely adjust over time will do the same.

When an entrepreneur buys up resources during low-demand times in anticipation of a crisis, she restricts supply ahead of the crisis, which leads to a price increase. She effectively bids up the price. The change in price affects consumers and producers in all the ways mentioned above. Consumers self-ration more, and producers bring more of the resource to market.

Our entrepreneur has done a truly incredible thing. She has predicted the future, and by so doing has caused every individual in the economy to prepare for a shortage they don't even know is coming! And, by discouraging consumption and encouraging production ahead of time, she blunts the impact the crisis will have. There will be more of the resource to go around when it is needed most.

On top of this, our entrepreneur still has her stockpile she saved back when everyone else was blithely using it up. She can now further mitigate the damage of the crisis by selling her stock during the worst of it, when people are most desperate for relief. She will know when this is because the price will tell her, but only if it is allowed to adjust freely. When the price is at its highest is when people need the resource the most, and those willing to pay will not waste it or hoard it. They will put it to its highest valued use.

The economy is like a big bus we are all riding in, going down a road with many twists and turns. Just as it is difficult to see into the future, it is difficult to see out the bus windows at the road ahead.

On the dashboard, we don't have a speedometer or fuel gauge. Instead we have all the prices for everything in the economy. Prices are what tell us the condition of the bus and the road. They tell us everything. Without them, we are blind.

Good times are a smooth road. Consumer prices and interest rates are low, investment returns are steady. We hit the gas and go fast. But, the road is not always straight and smooth. Sometimes there are sharp turns and rough patches. Successful entrepreneurs are the ones who can see what is coming better than everyone else. They are our navigators.

When they buy up scarce resources ahead of a crisis, they are hitting the brakes and slowing us down. When they divert resources from one area to another, they are steering us onto a smoother path. By their actions in the market, they adjust the prices on our dashboard to reflect the conditions of the road ahead, so we can prepare for, navigate and get through the inevitable difficulties we will face.

Interfering with the dashboard by imposing price floors or price caps doesn't change the conditions of the road (the number of toilet paper rolls in existence hasn't changed). All it does is distort our perception of those conditions. We think the road is still smooth--our heavy foot stomping the gas--as we crash onto a rocky dirt road at 80 miles per hour (empty shelves at the store for weeks on end).

Supply, demand and prices are laws of nature. All of this is just how things work. It isn't right or wrong in a moral sense. Price caps lead to waste, shortages and hoarding as surely as water flows downhill. The opposite--allowing prices to adjust freely--leads to conservation of scarce resources and their being put to their highest valued use. And yes, it leads to profits for the entrepreneurs who were able to correctly predict future conditions, and losses for those who weren't.

Is it fair that they should collect these profits? On the one hand, anyone could have stocked up on toilet paper, hand sanitizer and face masks at any time before the crisis, so we all had a fair chance to get the supplies cheaply. On the other hand, it just feels wrong that some should profit so much at a time when there is so much need.

Our instinct in the moment is to see the entrepreneur as a villain, greedy "price gouger". But we don't see the long chain of economic consequences the led to the situation we feel is unfair.

If it weren't for anti-price-gouging laws, the major retailers would have raised their prices long before the crisis became acute. When they saw demand outstrip supply, they would have raised prices, not by 100 fold, but gradually and long before anyone knew how serious things would have become. Late comers would have had to pay more, but at least there would be something left on the shelf.

As an entrepreneur, why take risks trying to anticipate the future if you can't reap the reward when you are right? Instead of letting instead of letting entrepreneurs--our navigators--guide us, we are punishing and vilifying them, trying to force prices to reflect a reality that simply doesn't exist.

In a crisis, more than any other time, prices must be allowed to fluctuate. To do otherwise is to blind ourselves at a time when danger and uncertainty abound. It is economic suicide.

In a crisis, there is great need, and the way to meet that need is not by pretending it's not there, by forcing prices to reflect a world where there isn't need. They way to meet the need is the same it has always been, through charity.

If the people in government want to help, the best way for the to do so is to be charitable and reduce their taxes and fees as much as possible, ideally to zero in a time of crisis. Amazon, for example, could instantly reduce the price of all crisis related necessities by 20% if they waived their fee. This would allow for more uses by more people of these scarce supplies as hoarders release their stockpiles on to the market, knowing they can get 20% more for their stock. Governments could reduce or eliminate their tax burden on high-demand, crisis-related items and all the factors that go into their production, with the same effect: a reduction in prices and expansion of supply. All of us, including the successful entrepreneurs and the wealthy for whom high prices are not a great burden, could donate to relief efforts.

These ideas are not new or untested. This is core micro economics. It has been taught for hundreds of years in universities the world over. The fact that every crisis that comes along stirs up ire against entrepreneurs indicates not that the economics is wrong, but that we have a strong visceral reaction against what we perceive to be unfairness. This is as it should be. Unfairness is wrong and the anger it stirs in us should compel us to right the wrong. Our anger itself isn't wrong, it's just misplaced.

Entrepreneurs didn't cause the prices to rise. Our reaction to a virus did that. We saw a serious threat and an uncertain future and followed our natural impulse to hoard. Because prices at major retail suppliers didn't rise, that impulse ran rampant and we cleared the shelves until there was nothing left. We ran the bus right off the road and them blamed the entrepreneurs for showing us the reality of our situation, for shaking us out of the fantasy of low prices.

All of this is not to say that entrepreneurs are high-minded public servants. They are just doing their job. Staking your money on an uncertain future is a risky business. There are big risks and big rewards. Most entrepreneurs just scrape by or lose their capital in failed ventures.

However, the ones that get it right must be allowed to keep their profits, or else no one will try and we'll all be driving blind. We need our navigators. It doesn't even matter if they know all the positive effects they are having on the rest of us and the economy as a whole. So long as they are buying low and selling high--so long as they are doing their job--they will be guiding the rest of us through the good times and the bad, down the open road and through the rough spots.

High-Level Overview

Bitcoin developers are currently debating a proposed change to how Bitcoin Core handles the OP_RETURN opcode — a mechanism that allows users to insert small amounts of data into the blockchain. Specifically, the controversy revolves around removing built-in filters that limit how much data can be stored using this feature (currently capped at 80 bytes).

Summary of Both Sides

Position A: Remove OP_RETURN Filters

Advocates: nostr:npub1ej493cmun8y9h3082spg5uvt63jgtewneve526g7e2urca2afrxqm3ndrm, nostr:npub12rv5lskctqxxs2c8rf2zlzc7xx3qpvzs3w4etgemauy9thegr43sf485vg, nostr:npub17u5dneh8qjp43ecfxr6u5e9sjamsmxyuekrg2nlxrrk6nj9rsyrqywt4tp, others

Arguments: - Ineffectiveness of filters: Filters are easily bypassed and do not stop spam effectively. - Code simplification: Removing arbitrary limits reduces code complexity. - Permissionless innovation: Enables new use cases like cross-chain bridges and timestamping without protocol-level barriers. - Economic regulation: Fees should determine what data gets added to the blockchain, not protocol rules.

Position B: Keep OP_RETURN Filters

Advocates: nostr:npub1lh273a4wpkup00stw8dzqjvvrqrfdrv2v3v4t8pynuezlfe5vjnsnaa9nk, nostr:npub1s33sw6y2p8kpz2t8avz5feu2n6yvfr6swykrnm2frletd7spnt5qew252p, nostr:npub1wnlu28xrq9gv77dkevck6ws4euej4v568rlvn66gf2c428tdrptqq3n3wr, others

Arguments: - Historical intent: Satoshi included filters to keep Bitcoin focused on monetary transactions. - Resource protection: Helps prevent blockchain bloat and abuse from non-financial uses. - Network preservation: Protects the network from being overwhelmed by low-value or malicious data. - Social governance: Maintains conservative changes to ensure long-term robustness.

Strengths and Weaknesses

Strengths of Removing Filters

• Encourages decentralized innovation.
• Simplifies development and maintenance.
• Maintains ideological purity of a permissionless system.

Weaknesses of Removing Filters

• Opens the door to increased non-financial data and potential spam.
• May dilute Bitcoin’s core purpose as sound money.
• Risks short-term exploitation before economic filters adapt.

Strengths of Keeping Filters

• Preserves Bitcoin’s identity and original purpose.
• Provides a simple protective mechanism against abuse.
• Aligns with conservative development philosophy of Bitcoin Core.

Weaknesses of Keeping Filters

• Encourages central decision-making on allowed use cases.
• Leads to workarounds that may be less efficient or obscure.
• Discourages novel but legitimate applications.

Long-Term Consequences

If Filters Are Removed

• Positive: Potential boom in new applications, better interoperability, cleaner architecture.
• Negative: Risk of increased blockchain size, more bandwidth/storage costs, spam wars.

If Filters Are Retained

• Positive: Preserves monetary focus and operational discipline.
• Negative: Alienates developers seeking broader use cases, may ossify the protocol.

Conclusion

The debate highlights a core philosophical split in Bitcoin: whether it should remain a narrow monetary system or evolve into a broader data layer for decentralized applications. Both paths carry risks and tradeoffs. The outcome will shape not just Bitcoin's technical direction but its social contract and future role in the broader crypto ecosystem.

Die Wahrheit verletzt tiefer als jede Beleidigung. \ Marquis de Sade

Sagen Sie niemals «Terroristin B.», «Schwachkopf H.», «korrupter Drecksack S.» oder «Meinungsfreiheitshasserin F.» und verkneifen Sie sich Memes, denn so etwas könnte Ihnen als Beleidigung oder Verleumdung ausgelegt werden und rechtliche Konsequenzen haben. Auch mit einer Frau M.-A. S.-Z. ist in dieser Beziehung nicht zu spaßen, sie gehört zu den Top-Anzeigenstellern.

«Politikerbeleidigung» als Straftatbestand wurde 2021 im Kampf gegen «Rechtsextremismus und Hasskriminalität» in Deutschland eingeführt, damals noch unter der Regierung Merkel. Im Gesetz nicht festgehalten ist die Unterscheidung zwischen schlechter Hetze und guter Hetze – trotzdem ist das gängige Praxis, wie der Titel fast schon nahelegt.

So dürfen Sie als Politikerin heute den Tesla als «Nazi-Auto» bezeichnen und dies ausdrücklich auf den Firmengründer Elon Musk und dessen «rechtsextreme Positionen» beziehen, welche Sie nicht einmal belegen müssen. [1] Vielleicht ernten Sie Proteste, jedoch vorrangig wegen der «gut bezahlten, unbefristeten Arbeitsplätze» in Brandenburg. Ihren Tweet hat die Berliner Senatorin Cansel Kiziltepe inzwischen offenbar dennoch gelöscht.

Dass es um die Meinungs- und Pressefreiheit in der Bundesrepublik nicht mehr allzu gut bestellt ist, befürchtet man inzwischen auch schon im Ausland. Der Fall des Journalisten David Bendels, der kürzlich wegen eines Faeser-Memes zu sieben Monaten Haft auf Bewährung verurteilt wurde, führte in diversen Medien zu Empörung. Die Welt versteckte ihre Kritik mit dem Titel «Ein Urteil wie aus einer Diktatur» hinter einer Bezahlschranke.

Unschöne, heutzutage vielleicht strafbare Kommentare würden mir auch zu einigen anderen Themen und Akteuren einfallen. Ein Kandidat wäre der deutsche Bundesgesundheitsminister (ja, er ist es tatsächlich immer noch). Während sich in den USA auf dem Gebiet etwas bewegt und zum Beispiel Robert F. Kennedy Jr. will, dass die Gesundheitsbehörde (CDC) keine Covid-Impfungen für Kinder mehr empfiehlt, möchte Karl Lauterbach vor allem das Corona-Lügengebäude vor dem Einsturz bewahren.

«Ich habe nie geglaubt, dass die Impfungen nebenwirkungsfrei sind», sagte Lauterbach jüngst der ZDF-Journalistin Sarah Tacke. Das steht in krassem Widerspruch zu seiner früher verbreiteten Behauptung, die Gen-Injektionen hätten keine Nebenwirkungen. Damit entlarvt er sich selbst als Lügner. Die Bezeichnung ist absolut berechtigt, dieser Mann dürfte keinerlei politische Verantwortung tragen und das Verhalten verlangt nach einer rechtlichen Überprüfung. Leider ist ja die Justiz anderweitig beschäftigt und hat außerdem selbst keine weiße Weste.

Obendrein kämpfte der Herr Minister für eine allgemeine Impfpflicht. Er beschwor dabei das Schließen einer «Impflücke», wie es die Weltgesundheitsorganisation – die «wegen Trump» in finanziellen Schwierigkeiten steckt – bis heute tut. Die WHO lässt aktuell ihre «Europäische Impfwoche» propagieren, bei der interessanterweise von Covid nicht mehr groß die Rede ist.

Einen «Klima-Leugner» würden manche wohl Nir Shaviv nennen, das ist ja nicht strafbar. Der Astrophysiker weist nämlich die Behauptung von einer Klimakrise zurück. Gemäß seiner Forschung ist mindestens die Hälfte der Erderwärmung nicht auf menschliche Emissionen, sondern auf Veränderungen im Sonnenverhalten zurückzuführen.

Das passt vielleicht auch den «Klima-Hysterikern» der britischen Regierung ins Konzept, die gerade Experimente zur Verdunkelung der Sonne angekündigt haben. Produzenten von Kunstfleisch oder Betreiber von Insektenfarmen würden dagegen vermutlich die Geschichte vom fatalen CO2 bevorzugen. Ihnen würde es besser passen, wenn der verantwortungsvolle Erdenbürger sein Verhalten gründlich ändern müsste.

In unserer völlig verkehrten Welt, in der praktisch jede Verlautbarung außerhalb der abgesegneten Narrative potenziell strafbar sein kann, gehört fast schon Mut dazu, Dinge offen anzusprechen. Im «besten Deutschland aller Zeiten» glaubten letztes Jahr nur noch 40 Prozent der Menschen, ihre Meinung frei äußern zu können. Das ist ein Armutszeugnis, und es sieht nicht gerade nach Besserung aus. Umso wichtiger ist es, dagegen anzugehen.

A Vision for #GitViaNostr

Git has long been the standard for version control in software development, but over time, we has lost its distributed nature. Originally, Git used open, permissionless email for collaboration, which worked well at scale. However, the rise of GitHub and its centralized pull request (PR) model has shifted the landscape.

Now, we have the opportunity to revive Git's permissionless and distributed nature through Nostr!

We’ve developed tools to facilitate Git collaboration via Nostr, but there are still significant friction that prevents widespread adoption. This article outlines a vision for how we can reduce those barriers and encourage more repositories to embrace this approach.

First, we’ll review our progress so far. Then, we’ll propose a guiding philosophy for our next steps. Finally, we’ll discuss a vision to tackle specific challenges, mainly relating to the role of the Git server and CI/CD.

I am the lead maintainer of ngit and gitworkshop.dev, and I’ve been fortunate to work full-time on this initiative for the past two years, thanks to an OpenSats grant.

How Far We’ve Come

The aim of #GitViaNostr is to liberate discussions around code collaboration from permissioned walled gardens. At the core of this collaboration is the process of proposing and applying changes. That's what we focused on first.

Since Nostr shares characteristics with email, and with NIP34, we’ve adopted similar primitives to those used in the patches-over-email workflow. This is because of their simplicity and that they don’t require contributors to host anything, which adds reliability and makes participation more accessible.

However, the fork-branch-PR-merge workflow is the only model many developers have known, and changing established workflows can be challenging. To address this, we developed a new workflow that balances familiarity, user experience, and alignment with the Nostr protocol: the branch-PR-merge model.

This model is implemented in ngit, which includes a Git plugin that allows users to engage without needing to learn new commands. Additionally, gitworkshop.dev offers a GitHub-like interface for interacting with PRs and issues. We encourage you to try them out using the quick start guide and share your feedback. You can also explore PRs and issues with gitplaza.

For those who prefer the patches-over-email workflow, you can still use that approach with Nostr through gitstr or the ngit send and ngit list commands, and explore patches with patch34.

The tools are now available to support the core collaboration challenge, but we are still at the beginning of the adoption curve.

Before we dive into the challenges—such as why the Git server setup can be jarring and the possibilities surrounding CI/CD—let’s take a moment to reflect on how we should approach the challenges ahead of us.

Philosophy

Here are some foundational principles I shared a few years ago:

• Let Git be Git
• Let Nostr be Nostr
• Learn from the successes of others

I’d like to add one more:

• Embrace anarchy and resist monolithic development.

Micro Clients FTW

Nostr celebrates simplicity, and we should strive to maintain that. Monolithic developments often lead to unnecessary complexity. Projects like gitworkshop.dev, which aim to cover various aspects of the code collaboration experience, should not stifle innovation.

Just yesterday, the launch of following.space demonstrated how vibe-coded micro clients can make a significant impact. They can be valuable on their own, shape the ecosystem, and help push large and widely used clients to implement features and ideas.

The primitives in NIP34 are straightforward, and if there are any barriers preventing the vibe-coding of a #GitViaNostr app in an afternoon, we should work to eliminate them.

Micro clients should lead the way and explore new workflows, experiences, and models of thinking.

Take kanbanstr.com. It provides excellent project management and organization features that work seamlessly with NIP34 primitives.

From kanban to code snippets, from CI/CD runners to SatShoot—may a thousand flowers bloom, and a thousand more after them.

Friction and Challenges

The Git Server

In #GitViaNostr, maintainers' branches (e.g., master) are hosted on a Git server. Here’s why this approach is beneficial:

• Follows the original Git vision and the "let Git be Git" philosophy.
• Super efficient, battle-tested, and compatible with all the ways people use Git (e.g., LFS, shallow cloning).
• Maintains compatibility with related systems without the need for plugins (e.g., for build and deployment).
• Only repository maintainers need write access.

In the original Git model, all users would need to add the Git server as a 'git remote.' However, with ngit, the Git server is hidden behind a Nostr remote, which enables:

• Hiding complexity from contributors and users, so that only maintainers need to know about the Git server component to start using #GitViaNostr.
• Maintainers can easily swap Git servers by updating their announcement event, allowing contributors/users using ngit to automatically switch to the new one.

Challenges with the Git Server

While the Git server model has its advantages, it also presents several challenges:

1. Initial Setup: When creating a new repository, maintainers must select a Git server, which can be a jarring experience. Most options come with bloated social collaboration features tied to a centralized PR model, often difficult or impossible to disable.

2. Manual Configuration: New repositories require manual configuration, including adding new maintainers through a browser UI, which can be cumbersome and time-consuming.

3. User Onboarding: Many Git servers require email sign-up or KYC (Know Your Customer) processes, which can be a significant turn-off for new users exploring a decentralized and permissionless alternative to GitHub.

Once the initial setup is complete, the system works well if a reliable Git server is chosen. However, this is a significant "if," as we have become accustomed to the excellent uptime and reliability of GitHub. Even professionally run alternatives like Codeberg can experience downtime, which is frustrating when CI/CD and deployment processes are affected. This problem is exacerbated when self-hosting.

Currently, most repositories on Nostr rely on GitHub as the Git server. While maintainers can change servers without disrupting their contributors, this reliance on a centralized service is not the decentralized dream we aspire to achieve.

Vision for the Git Server

The goal is to transform the Git server from a single point of truth and failure into a component similar to a Nostr relay.

Functionality Already in ngit to Support This

1. State on Nostr: Store the state of branches and tags in a Nostr event, removing reliance on a single server. This validates that the data received has been signed by the maintainer, significantly reducing the trust requirement.

2. Proxy to Multiple Git Servers: Proxy requests to all servers listed in the announcement event, adding redundancy and eliminating the need for any one server to match GitHub's reliability.

Implementation Requirements

To achieve this vision, the Nostr Git server implementation should:

1. Implement the Git Smart HTTP Protocol without authentication (no SSH) and only accept pushes if the reference tip matches the latest state event.

2. Avoid Bloat: There should be no user authentication, no database, no web UI, and no unnecessary features.

3. Automatic Repository Management: Accept or reject new repositories automatically upon the first push based on the content of the repository announcement event referenced in the URL path and its author.

Just as there are many free, paid, and self-hosted relays, there will be a variety of free, zero-step signup options, as well as self-hosted and paid solutions.

Some servers may use a Web of Trust (WoT) to filter out spam, while others might impose bandwidth or repository size limits for free tiers or whitelist specific npubs.

Additionally, some implementations could bundle relay and blossom server functionalities to unify the provision of repository data into a single service. These would likely only accept content related to the stored repositories rather than general social nostr content.

The potential role of CI / CD via nostr DVMs could create the incentives for a market of highly reliable free at the point of use git servers.

This could make onboarding #GitViaNostr repositories as easy as entering a name and selecting from a multi-select list of Git server providers that announce via NIP89.

Git Client in the Browser

Currently, many tasks are performed on a Git server web UI, such as:

• Browsing code, commits, branches, tags, etc.
• Creating and displaying permalinks to specific lines in commits.
• Merging PRs.
• Making small commits and PRs on-the-fly.

Just as nobody goes to the web UI of a relay (e.g., nos.lol) to interact with notes, nobody should need to go to a Git server to interact with repositories. We use the Nostr protocol to interact with Nostr relays, and we should use the Git protocol to interact with Git servers. This situation has evolved due to the centralization of Git servers. Instead of being restricted to the view and experience designed by the server operator, users should be able to choose the user experience that works best for them from a range of clients. To facilitate this, we need a library that lowers the barrier to entry for creating these experiences. This library should not require a full clone of every repository and should not depend on proprietary APIs. As a starting point, I propose wrapping the WASM-compiled gitlib2 library for the web and creating useful functions, such as showing a file, which utilizes clever flags to minimize bandwidth usage (e.g., shallow clone, noblob, etc.).

This approach would not only enhance clients like gitworkshop.dev but also bring forth a vision where Git servers simply run the Git protocol, making vibe coding Git experiences even better.

song

nostr:npub180cvv07tjdrrgpa0j7j7tmnyl2yr6yr7l8j4s3evf6u64th6gkwsyjh6w6 created song with a complementary vision that has shaped how I see the role of the git server. Its a self-hosted, nostr-permissioned git server with a relay baked in. Its currently a WIP and there are some compatability with ngit that we need to work out.

We collaborated on the nostr-permissioning approach now reflected in nip34.

I'm really excited to see how this space evolves.

CI/CD

Most projects require CI/CD, and while this is often bundled with Git hosting solutions, it is currently not smoothly integrated into #GitViaNostr yet. There are many loosely coupled options, such as Jenkins, Travis, CircleCI, etc., that could be integrated with Nostr.

However, the more exciting prospect is to use DVMs (Data Vending Machines).

DVMs for CI/CD

Nostr Data Vending Machines (DVMs) can provide a marketplace of CI/CD task runners with Cashu for micro payments.

There are various trust levels in CI/CD tasks:

• Tasks with no secrets eg. tests.
• Tasks using updatable secrets eg. API keys.
• Unverifiable builds and steps that sign with Android, Nostr, or PGP keys.

DVMs allow tasks to be kicked off with specific providers using a Cashu token as payment.

It might be suitable for some high-compute and easily verifiable tasks to be run by the cheapest available providers. Medium trust tasks could be run by providers with a good reputation, while high trust tasks could be run on self-hosted runners.

Job requests, status, and results all get published to Nostr for display in Git-focused Nostr clients.

Jobs could be triggered manually, or self-hosted runners could be configured to watch a Nostr repository and kick off jobs using their own runners without payment.

But I'm most excited about the prospect of Watcher Agents.

CI/CD Watcher Agents

AI agents empowered with a NIP60 Cashu wallet can run tasks based on activity, such as a push to master or a new PR, using the most suitable available DVM runner that meets the user's criteria. To keep them running, anyone could top up their NIP60 Cashu wallet; otherwise, the watcher turns off when the funds run out. It could be users, maintainers, or anyone interested in helping the project who could top up the Watcher Agent's balance.

As aluded to earlier, part of building a reputation as a CI/CD provider could involve running reliable hosting (Git server, relay, and blossom server) for all FOSS Nostr Git repositories.

This provides a sustainable revenue model for hosting providers and creates incentives for many free-at-the-point-of-use hosting providers. This, in turn, would allow one-click Nostr repository creation workflows, instantly hosted by many different providers.

Progress to Date

nostr:npub1hw6amg8p24ne08c9gdq8hhpqx0t0pwanpae9z25crn7m9uy7yarse465gr and nostr:npub16ux4qzg4qjue95vr3q327fzata4n594c9kgh4jmeyn80v8k54nhqg6lra7 have been working on a runner that uses GitHub Actions YAML syntax (using act) for the dvm-cicd-runner and takes Cashu payment. You can see example runs on GitWorkshop. It currently takes testnuts, doesn't give any change, and the schema will likely change.

Note: The actions tab on GitWorkshop is currently available on all repositories if you turn on experimental mode (under settings in the user menu).

It's a work in progress, and we expect the format and schema to evolve.

Easy Web App Deployment

For those disapointed not to find a 'Nostr' button to import a git repository to Vercel menu: take heart, they made it easy. vercel.com_import_options.png there is a vercel cli that can be easily called in CI / CD jobs to kick of deployments. Not all managed solutions for web app deployment (eg. netlify) make it that easy.

Many More Opportunities

Large Patches via Blossom

I would be remiss not to mention the large patch problem. Some patches are too big to fit into Nostr events. Blossom is perfect for this, as it allows these larger patches to be included in a blossom file and referenced in a new patch kind.

Enhancing the #GitViaNostr Experience

Beyond the large patch issue, there are numerous opportunities to enhance the #GitViaNostr ecosystem. We can focus on improving browsing, discovery, social and notifications. Receiving notifications on daily driver Nostr apps is one of the killer features of Nostr. However, we must ensure that Git-related notifications are easily reviewable, so we don’t miss any critical updates.

We need to develop tools that cater to our curiosity—tools that enable us to discover and follow projects, engage in discussions that pique our interest, and stay informed about developments relevant to our work.

Additionally, we should not overlook the importance of robust search capabilities and tools that facilitate migrations.

Concluding Thoughts

The design space is vast. Its an exciting time to be working on freedom tech. I encourage everyone to contribute their ideas and creativity and get vibe-coding!

I welcome your honest feedback on this vision and any suggestions you might have. Your insights are invaluable as we collaborate to shape the future of #GitViaNostr. Onward.

MLS over Nostr - 30th April 2025

YO! Exciting stuff in this update so no intro, let's get straight into it.

🚢 Libraries Released

I've created 4 new Rust crates to make implementing NIP-EE (MLS) messaging easy for other projects. These are now part of the rust-nostr project (thanks nostr:npub1drvpzev3syqt0kjrls50050uzf25gehpz9vgdw08hvex7e0vgfeq0eseet) but aren't quite released to crates.io yet. They will be included in the next release of that library. My hope is that these libraries will give nostr developers a simple, safe, and specification-compliant way to work with MLS messaging in their applications.

Here's a quick overview of each:

nostr_mls_storage

One of the challenges of using MLS messaging is that clients have to store quite a lot of state about groups, keys, and messages. Initially, I implemented all of this in White Noise but knew that eventually this would need to be done in a more generalized way.

This crate defines traits and types that are used by the storage implementation crates and sets those up to wrap the OpenMLS storage layer. Now, instead of apps having to implement storage for both OpenMLS and Nostr, you simply pick your storage backend and go from there.

Importantly, because these are generic traits, it allows for the creation of any number of storage implementations for different backend storage providers; postgres, lmdb, nostrdb, etc. To start I've created two implementations; detailed below.

nostr_mls_memory_storage

This is a simple implementation of the nostr_mls_storage traits that uses an in-memory store (that doesn't persist anything to disc). This is principally for testing.

nostr_mls_sqlite_storage

This is a production ready implementation of the nostr_mls_storage traits that uses a persistent local sqlite database to store all data.

nostr_mls

This is the main library that app developers will interact with. Once you've chose a backend and instantiated an instance of NostrMls you can then interact with a simple set of methods to create key packages, create groups, send messages, process welcomes and messages, and more.

If you want to see a complete example of what the interface looks like check out mls_memory.rs.

I'll continue to add to this library over time as I implement more of the MLS protocol features.

🚧 White Noise Refactor

As a result of these new libraries, I was able to remove a huge amount of code from White Noise and refactor large parts of the app to make the codebase easier to understand and maintain. Because of this large refactor and the changes in the underlying storage layer, if you've installed White Noise before you'll need to delete it from your device before you trying to install again.

🖼️ Encrypted Media with Blossom

Let's be honest: Group chat would be basically useless if you couldn't share memes and gifs. Well, now you can in White Noise. Media in groups is encrypted using an MLS secret and uploaded to Blossom with a one-time use keypair. This gives groups a way to have rich conversations with images and documents and anything else while also maintaining the privacy and security of the conversation.

This is still in a rough state but rendering improvements are coming next.

📱 Damn Mobile

The app is still in a semi-broken state on Android and fully broken state on iOS. Now that I have the libraries released and the White Noise core code refactored, I'm focused 100% on fixing these issues. My goal is to have a beta version live on Zapstore in a few weeks.

🧑‍💻 Join Us

I'm looking for mobile developers on both Android and iOS to join the team and help us build the best possible apps for these platforms. I have grant funding available for the right people. Come and help us build secure, permissionless, censorship-resistant messaging. I can think of few projects that deserve your attention more than securing freedom of speech and freedom of association for the entire world. If you're interested or know someone who might be, please reach out to me directly.

🙏 Thanks to the People

Last but not least: A HUGE thank you to all the folks that have been helping make this project happen. You can check out the people that are directly working on the apps on Following._ (and follow them). There are also a lot of people behind the scenes that have helped in myriad ways to get us this far. Thank you thank you thank you.

Es ist völlig unbestritten, dass der Angriff der russischen Armee auf die Ukraine im Februar 2022 strikt zu verurteilen ist. Ebenso unbestritten ist Russland unter Wladimir Putin keine brillante Demokratie. Aus diesen Tatsachen lässt sich jedoch nicht das finstere Bild des russischen Präsidenten – und erst recht nicht des Landes – begründen, das uns durchweg vorgesetzt wird und den Kern des aktuellen europäischen Bedrohungs-Szenarios darstellt. Da müssen wir schon etwas genauer hinschauen.

Der vorliegende Artikel versucht derweil nicht, den Einsatz von Gewalt oder die Verletzung von Menschenrechten zu rechtfertigen oder zu entschuldigen – ganz im Gegenteil. Dass jedoch der Verdacht des «Putinverstehers» sofort latent im Raume steht, verdeutlicht, was beim Thema «Russland» passiert: Meinungsmache und Manipulation.

Angesichts der mentalen Mobilmachung seitens Politik und Medien sowie des Bestrebens, einen bevorstehenden Krieg mit Russland geradezu herbeizureden, ist es notwendig, dieser fatalen Entwicklung entgegenzutreten. Wenn wir uns nur ein wenig von der herrschenden Schwarz-Weiß-Malerei freimachen, tauchen automatisch Fragen auf, die Risse im offiziellen Narrativ enthüllen. Grund genug, nachzuhaken.

Wer sich schon länger auch abseits der Staats- und sogenannten Leitmedien informiert, der wird in diesem Artikel vermutlich nicht viel Neues erfahren. Andere könnten hier ein paar unbekannte oder vergessene Aspekte entdecken. Möglicherweise klärt sich in diesem Kontext die Wahrnehmung der aktuellen (unserer eigenen!) Situation ein wenig.

Manipulation erkennen

Corona-«Pandemie», menschengemachter Klimawandel oder auch Ukraine-Krieg: Jede Menge Krisen, und für alle gibt es ein offizielles Narrativ, dessen Hinterfragung unerwünscht ist. Nun ist aber ein Narrativ einfach eine Erzählung, eine Geschichte (Latein: «narratio») und kein Tatsachenbericht. Und so wie ein Märchen soll auch das Narrativ eine Botschaft vermitteln.

Über die Methoden der Manipulation ist viel geschrieben worden, sowohl in Bezug auf das Individuum als auch auf die Massen. Sehr wertvolle Tipps dazu, wie man Manipulationen durchschauen kann, gibt ein Büchlein [1] von Albrecht Müller, dem Herausgeber der NachDenkSeiten.

Die Sprache selber eignet sich perfekt für die Manipulation. Beispielsweise kann die Wortwahl Bewertungen mitschwingen lassen, regelmäßiges Wiederholen (gerne auch von verschiedenen Seiten) lässt Dinge irgendwann «wahr» erscheinen, Übertreibungen fallen auf und hinterlassen wenigstens eine Spur im Gedächtnis, genauso wie Andeutungen. Belege spielen dabei keine Rolle.

Es gibt auffällig viele Sprachregelungen, die offenbar irgendwo getroffen und irgendwie koordiniert werden. Oder alle Redenschreiber und alle Medien kopieren sich neuerdings permanent gegenseitig. Welchen Zweck hat es wohl, wenn der Krieg in der Ukraine durchgängig und quasi wörtlich als «russischer Angriffskrieg auf die Ukraine» bezeichnet wird? Obwohl das in der Sache richtig ist, deutet die Art der Verwendung auf gezielte Beeinflussung hin und soll vor allem das Feindbild zementieren.

Sprachregelungen dienen oft der Absicherung einer einseitigen Darstellung. Das Gleiche gilt für das Verkürzen von Informationen bis hin zum hartnäckigen Verschweigen ganzer Themenbereiche. Auch hierfür gibt es rund um den Ukraine-Konflikt viele gute Beispiele.

Das gewünschte Ergebnis solcher Methoden ist eine Schwarz-Weiß-Malerei, bei der einer eindeutig als «der Böse» markiert ist und die anderen automatisch «die Guten» sind. Das ist praktisch und demonstriert gleichzeitig ein weiteres Manipulationswerkzeug: die Verwendung von Doppelstandards. Wenn man es schafft, bei wichtigen Themen regelmäßig mit zweierlei Maß zu messen, ohne dass das Publikum protestiert, dann hat man freie Bahn.

Experten zu bemühen, um bestimmte Sachverhalte zu erläutern, ist sicher sinnvoll, kann aber ebenso missbraucht werden, schon allein durch die Auswahl der jeweiligen Spezialisten. Seit «Corona» werden viele erfahrene und ehemals hoch angesehene Fachleute wegen der «falschen Meinung» diffamiert und gecancelt. [2] Das ist nicht nur ein brutaler Umgang mit Menschen, sondern auch eine extreme Form, die öffentliche Meinung zu steuern.

Wann immer wir also erkennen (weil wir aufmerksam waren), dass wir bei einem bestimmten Thema manipuliert werden, dann sind zwei logische und notwendige Fragen: Warum? Und was ist denn richtig? In unserem Russland-Kontext haben die Antworten darauf viel mit Geopolitik und Geschichte zu tun.

Ist Russland aggressiv und expansiv?

Angeblich plant Russland, europäische NATO-Staaten anzugreifen, nach dem Motto: «Zuerst die Ukraine, dann den Rest». In Deutschland weiß man dafür sogar das Datum: «Wir müssen bis 2029 kriegstüchtig sein», versichert Verteidigungsminister Pistorius.

Historisch gesehen ist es allerdings eher umgekehrt: Russland, bzw. die Sowjetunion, ist bereits dreimal von Westeuropa aus militärisch angegriffen worden. Die Feldzüge Napoleons, des deutschen Kaiserreichs und Nazi-Deutschlands haben Millionen Menschen das Leben gekostet. Bei dem ausdrücklichen Vernichtungskrieg ab 1941 kam es außerdem zu Brutalitäten wie der zweieinhalbjährigen Belagerung Leningrads (heute St. Petersburg) durch Hitlers Wehrmacht. Deren Ziel, die Bevölkerung auszuhungern, wurde erreicht: über eine Million tote Zivilisten.

Trotz dieser Erfahrungen stimmte Michail Gorbatschow 1990 der deutschen Wiedervereinigung zu und die Sowjetunion zog ihre Truppen aus Osteuropa zurück (vgl. Abb. 1). Der Warschauer Pakt wurde aufgelöst, der Kalte Krieg formell beendet. Die Sowjets erhielten damals von führenden westlichen Politikern die Zusicherung, dass sich die NATO «keinen Zentimeter ostwärts» ausdehnen würde, das ist dokumentiert. [3]

Expandiert ist die NATO trotzdem, und zwar bis an Russlands Grenzen (vgl. Abb. 2). Laut dem Politikberater Jeffrey Sachs handelt es sich dabei um ein langfristiges US-Projekt, das von Anfang an die Ukraine und Georgien mit einschloss. Offiziell wurde der Beitritt beiden Staaten 2008 angeboten. In jedem Fall könnte die massive Ost-Erweiterung seit 1999 aus russischer Sicht nicht nur als Vertrauensbruch, sondern durchaus auch als aggressiv betrachtet werden.

Russland hat den europäischen Staaten mehrfach die Hand ausgestreckt [4] für ein friedliches Zusammenleben und den «Aufbau des europäischen Hauses». Präsident Putin sei «in seiner ersten Amtszeit eine Chance für Europa» gewesen, urteilt die Journalistin und langjährige Russland-Korrespondentin der ARD, Gabriele Krone-Schmalz. Er habe damals viele positive Signale Richtung Westen gesendet.

Die Europäer jedoch waren scheinbar an einer Partnerschaft mit dem kontinentalen Nachbarn weniger interessiert als an der mit dem transatlantischen Hegemon. Sie verkennen bis heute, dass eine gedeihliche Zusammenarbeit in Eurasien eine Gefahr für die USA und deren bekundetes Bestreben ist, die «einzige Weltmacht» zu sein – «Full Spectrum Dominance» [5] nannte das Pentagon das. Statt einem neuen Kalten Krieg entgegenzuarbeiten, ließen sich europäische Staaten selber in völkerrechtswidrige «US-dominierte Angriffskriege» [6] verwickeln, wie in Serbien, Afghanistan, dem Irak, Libyen oder Syrien. Diese werden aber selten so benannt.

Speziell den Deutschen stünde außer einer Portion Realismus auch etwas mehr Dankbarkeit gut zu Gesicht. Das Geschichtsbewusstsein der Mehrheit scheint doch recht selektiv und das Selbstbewusstsein einiger etwas desorientiert zu sein. Bekanntermaßen waren es die Soldaten der sowjetischen Roten Armee, die unter hohen Opfern 1945 Deutschland «vom Faschismus befreit» haben. Bei den Gedenkfeiern zu 80 Jahren Kriegsende will jedoch das Auswärtige Amt – noch unter der Diplomatie-Expertin Baerbock, die sich schon länger offiziell im Krieg mit Russland wähnt, – nun keine Russen sehen: Sie sollen notfalls rausgeschmissen werden.

«Die Grundsatzfrage lautet: Geht es Russland um einen angemessenen Platz in einer globalen Sicherheitsarchitektur, oder ist Moskau schon seit langem auf einem imperialistischen Trip, der befürchten lassen muss, dass die Russen in fünf Jahren in Berlin stehen?»

So bringt Gabriele Krone-Schmalz [7] die eigentliche Frage auf den Punkt, die zur Einschätzung der Situation letztlich auch jeder für sich beantworten muss.

Was ist los in der Ukraine?

In der internationalen Politik geht es nie um Demokratie oder Menschenrechte, sondern immer um Interessen von Staaten. Diese These stammt von Egon Bahr, einem der Architekten der deutschen Ostpolitik des «Wandels durch Annäherung» aus den 1960er und 70er Jahren. Sie trifft auch auf den Ukraine-Konflikt zu, den handfeste geostrategische und wirtschaftliche Interessen beherrschen, obwohl dort angeblich «unsere Demokratie» verteidigt wird.

Es ist ein wesentliches Element des Ukraine-Narrativs und Teil der Manipulation, die Vorgeschichte des Krieges wegzulassen – mindestens die vor der russischen «Annexion» der Halbinsel Krim im März 2014, aber oft sogar komplett diejenige vor der Invasion Ende Februar 2022. Das Thema ist komplex, aber einige Aspekte, die für eine Beurteilung nicht unwichtig sind, will ich wenigstens kurz skizzieren. [8]

Das Gebiet der heutigen Ukraine und Russlands – die übrigens in der «Kiewer Rus» gemeinsame Wurzeln haben – hat der britische Geostratege Halford Mackinder bereits 1904 als eurasisches «Heartland» bezeichnet, dessen Kontrolle er eine große Bedeutung für die imperiale Strategie Großbritanniens zumaß. Für den ehemaligen Sicherheits- und außenpolitischen Berater mehrerer US-amerikanischer Präsidenten und Mitgründer der Trilateralen Kommission, Zbigniew Brzezinski, war die Ukraine nach der Auflösung der Sowjetunion ein wichtiger Spielstein auf dem «eurasischen Schachbrett», wegen seiner Nähe zu Russland, seiner Bodenschätze und seines Zugangs zum Schwarzen Meer.

Die Ukraine ist seit langem ein gespaltenes Land. Historisch zerrissen als Spielball externer Interessen und geprägt von ethnischen, kulturellen, religiösen und geografischen Unterschieden existiert bis heute, grob gesagt, eine Ost-West-Spaltung, welche die Suche nach einer nationalen Identität stark erschwert.

Insbesondere im Zuge der beiden Weltkriege sowie der Russischen Revolution entstanden tiefe Risse in der Bevölkerung. Ukrainer kämpften gegen Ukrainer, zum Beispiel die einen auf der Seite von Hitlers faschistischer Nazi-Armee und die anderen auf der von Stalins kommunistischer Roter Armee. Die Verbrechen auf beiden Seiten sind nicht vergessen. Dass nach der Unabhängigkeit 1991 versucht wurde, Figuren wie den radikalen Nationalisten Symon Petljura oder den Faschisten und Nazi-Kollaborateur Stepan Bandera als «Nationalhelden» zu installieren, verbessert die Sache nicht.

Während die USA und EU-Staaten zunehmend «ausländische Einmischung» (speziell russische) in «ihre Demokratien» wittern, betreiben sie genau dies seit Jahrzehnten in vielen Ländern der Welt. Die seit den 2000er Jahren bekannten «Farbrevolutionen» in Osteuropa werden oft als Methode des Regierungsumsturzes durch von außen gesteuerte «demokratische» Volksaufstände beschrieben. Diese Strategie geht auf Analysen zum «Schwarmverhalten» [9] seit den 1960er Jahren zurück (Studentenproteste), wo es um die potenzielle Wirksamkeit einer «rebellischen Hysterie» von Jugendlichen bei postmodernen Staatsstreichen geht. Heute nennt sich dieses gezielte Kanalisieren der Massen zur Beseitigung unkooperativer Regierungen «Soft-Power».

In der Ukraine gab es mit der «Orangen Revolution» 2004 und dem «Euromaidan» 2014 gleich zwei solcher «Aufstände». Der erste erzwang wegen angeblicher Unregelmäßigkeiten eine Wiederholung der Wahlen, was mit Wiktor Juschtschenko als neuem Präsidenten endete. Dieser war ehemaliger Direktor der Nationalbank und Befürworter einer Annäherung an EU und NATO. Seine Frau, die First Lady, ist US-amerikanische «Philanthropin» und war Beamtin im Weißen Haus in der Reagan- und der Bush-Administration.

Im Gegensatz zu diesem ersten Event endete der sogenannte Euromaidan unfriedlich und blutig. Die mehrwöchigen Proteste gegen Präsident Wiktor Janukowitsch, in Teilen wegen des nicht unterzeichneten Assoziierungsabkommens mit der EU, wurden zunehmend gewalttätiger und von Nationalisten und Faschisten des «Rechten Sektors» dominiert. Sie mündeten Ende Februar 2014 auf dem Kiewer Unabhängigkeitsplatz (Maidan) in einem Massaker durch Scharfschützen. Dass deren Herkunft und die genauen Umstände nicht geklärt wurden, störte die Medien nur wenig. [10]

Janukowitsch musste fliehen, er trat nicht zurück. Vielmehr handelte es sich um einen gewaltsamen, allem Anschein nach vom Westen inszenierten Putsch. Laut Jeffrey Sachs war das kein Geheimnis, außer vielleicht für die Bürger. Die USA unterstützten die Post-Maidan-Regierung nicht nur, sie beeinflussten auch ihre Bildung. Das geht unter anderem aus dem berühmten «Fuck the EU»-Telefonat der US-Chefdiplomatin für die Ukraine, Victoria Nuland, mit Botschafter Geoffrey Pyatt hervor.

Dieser Bruch der demokratischen Verfassung war letztlich der Auslöser für die anschließenden Krisen auf der Krim und im Donbass (Ostukraine). Angesichts der ukrainischen Geschichte mussten die nationalistischen Tendenzen und die Beteiligung der rechten Gruppen an dem Umsturz bei der russigsprachigen Bevölkerung im Osten ungute Gefühle auslösen. Es gab Kritik an der Übergangsregierung, Befürworter einer Abspaltung und auch für einen Anschluss an Russland.

Ebenso konnte Wladimir Putin in dieser Situation durchaus Bedenken wegen des Status der russischen Militärbasis für seine Schwarzmeerflotte in Sewastopol auf der Krim haben, für die es einen langfristigen Pachtvertrag mit der Ukraine gab. Was im März 2014 auf der Krim stattfand, sei keine Annexion, sondern eine Abspaltung (Sezession) nach einem Referendum gewesen, also keine gewaltsame Aneignung, urteilte der Rechtswissenschaftler Reinhard Merkel in der FAZ sehr detailliert begründet. Übrigens hatte die Krim bereits zu Zeiten der Sowjetunion den Status einer autonomen Republik innerhalb der Ukrainischen SSR.

Anfang April 2014 wurden in der Ostukraine die «Volksrepubliken» Donezk und Lugansk ausgerufen. Die Kiewer Übergangsregierung ging unter der Bezeichnung «Anti-Terror-Operation» (ATO) militärisch gegen diesen, auch von Russland instrumentalisierten Widerstand vor. Zufällig war kurz zuvor CIA-Chef John Brennan in Kiew. Die Maßnahmen gingen unter dem seit Mai neuen ukrainischen Präsidenten, dem Milliardär Petro Poroschenko, weiter. Auch Wolodymyr Selenskyj beendete den Bürgerkrieg nicht, als er 2019 vom Präsidenten-Schauspieler, der Oligarchen entmachtet, zum Präsidenten wurde. Er fuhr fort, die eigene Bevölkerung zu bombardieren.

Mit dem Einmarsch russischer Truppen in die Ostukraine am 24. Februar 2022 begann die zweite Phase des Krieges. Die Wochen und Monate davor waren intensiv. Im November hatte die Ukraine mit den USA ein Abkommen über eine «strategische Partnerschaft» unterzeichnet. Darin sagten die Amerikaner ihre Unterstützung der EU- und NATO-Perspektive der Ukraine sowie quasi für die Rückeroberung der Krim zu. Dagegen ließ Putin der NATO und den USA im Dezember 2021 einen Vertragsentwurf über beiderseitige verbindliche Sicherheitsgarantien zukommen, den die NATO im Januar ablehnte. Im Februar eskalierte laut OSZE die Gewalt im Donbass.

Bereits wenige Wochen nach der Invasion, Ende März 2022, kam es in Istanbul zu Friedensverhandlungen, die fast zu einer Lösung geführt hätten. Dass der Krieg nicht damals bereits beendet wurde, lag daran, dass der Westen dies nicht wollte. Man war der Meinung, Russland durch die Ukraine in diesem Stellvertreterkrieg auf Dauer militärisch schwächen zu können. Angesichts von Hunderttausenden Toten, Verletzten und Traumatisierten, die als Folge seitdem zu beklagen sind, sowie dem Ausmaß der Zerstörung, fehlen einem die Worte.

Hasst der Westen die Russen?

Diese Frage drängt sich auf, wenn man das oft unerträglich feindselige Gebaren beobachtet, das beileibe nicht neu ist und vor Doppelmoral trieft. Russland und speziell die Person Wladimir Putins werden regelrecht dämonisiert, was gleichzeitig scheinbar jede Form von Diplomatie ausschließt.

Russlands militärische Stärke, seine geografische Lage, sein Rohstoffreichtum oder seine unabhängige diplomatische Tradition sind sicher Störfaktoren für das US-amerikanische Bestreben, der Boss in einer unipolaren Welt zu sein. Ein womöglich funktionierender eurasischer Kontinent, insbesondere gute Beziehungen zwischen Russland und Deutschland, war indes schon vor dem Ersten Weltkrieg eine Sorge des britischen Imperiums.

Ein «Vergehen» von Präsident Putin könnte gewesen sein, dass er die neoliberale Schocktherapie à la IWF und den Ausverkauf des Landes (auch an US-Konzerne) beendete, der unter seinem Vorgänger herrschte. Dabei zeigte er sich als Führungspersönlichkeit und als nicht so formbar wie Jelzin. Diese Aspekte allein sind aber heute vermutlich keine ausreichende Erklärung für ein derart gepflegtes Feindbild.

Der Historiker und Philosoph Hauke Ritz erweitert den Fokus der Fragestellung zu: «Warum hasst der Westen die Russen so sehr?», was er zum Beispiel mit dem Medienforscher Michael Meyen und mit der Politikwissenschaftlerin Ulrike Guérot bespricht. Ritz stellt die interessante These [11] auf, dass Russland eine Provokation für den Westen sei, welcher vor allem dessen kulturelles und intellektuelles Potenzial fürchte.

Die Russen sind Europäer aber anders, sagt Ritz. Diese «Fremdheit in der Ähnlichkeit» erzeuge vielleicht tiefe Ablehnungsgefühle. Obwohl Russlands Identität in der europäischen Kultur verwurzelt ist, verbinde es sich immer mit der Opposition in Europa. Als Beispiele nennt er die Kritik an der katholischen Kirche oder die Verbindung mit der Arbeiterbewegung. Christen, aber orthodox; Sozialismus statt Liberalismus. Das mache das Land zum Antagonisten des Westens und zu einer Bedrohung der Machtstrukturen in Europa.

Fazit

Selbstverständlich kann man Geschichte, Ereignisse und Entwicklungen immer auf verschiedene Arten lesen. Dieser Artikel, obwohl viel zu lang, konnte nur einige Aspekte der Ukraine-Tragödie anreißen, die in den offiziellen Darstellungen in der Regel nicht vorkommen. Mindestens dürfte damit jedoch klar geworden sein, dass die Russische Föderation bzw. Wladimir Putin nicht der alleinige Aggressor in diesem Konflikt ist. Das ist ein Stellvertreterkrieg zwischen USA/NATO (gut) und Russland (böse); die Ukraine (edel) wird dabei schlicht verheizt.

Das ist insofern von Bedeutung, als die gesamte europäische Kriegshysterie auf sorgsam kultivierten Freund-Feind-Bildern beruht. Nur so kann Konfrontation und Eskalation betrieben werden, denn damit werden die wahren Hintergründe und Motive verschleiert. Angst und Propaganda sind notwendig, damit die Menschen den Wahnsinn mitmachen. Sie werden belogen, um sie zuerst zu schröpfen und anschließend auf die Schlachtbank zu schicken. Das kann niemand wollen, außer den stets gleichen Profiteuren: die Rüstungs-Lobby und die großen Investoren, die schon immer an Zerstörung und Wiederaufbau verdient haben.

Apropos Investoren: Zu den Top-Verdienern und somit Hauptinteressenten an einer Fortführung des Krieges zählt BlackRock, einer der weltgrößten Vermögensverwalter. Der deutsche Bundeskanzler in spe, Friedrich Merz, der gerne «Taurus»-Marschflugkörper an die Ukraine liefern und die Krim-Brücke zerstören möchte, war von 2016 bis 2020 Aufsichtsratsvorsitzender von BlackRock in Deutschland. Aber das hat natürlich nichts zu sagen, der Mann macht nur seinen Job.

Es ist ein Spiel der Kräfte, es geht um Macht und strategische Kontrolle, um Geheimdienste und die Kontrolle der öffentlichen Meinung, um Bodenschätze, Rohstoffe, Pipelines und Märkte. Das klingt aber nicht sexy, «Demokratie und Menschenrechte» hört sich besser und einfacher an. Dabei wäre eine für alle Seiten förderliche Politik auch nicht so kompliziert; das Handwerkszeug dazu nennt sich Diplomatie. Noch einmal Gabriele Krone-Schmalz:

«Friedliche Politik ist nichts anderes als funktionierender Interessenausgleich. Da geht’s nicht um Moral.»

Die Situation in der Ukraine ist sicher komplex, vor allem wegen der inneren Zerrissenheit. Es dürfte nicht leicht sein, eine friedliche Lösung für das Zusammenleben zu finden, aber die Beteiligten müssen es vor allem wollen. Unter den gegebenen Umständen könnte eine sinnvolle Perspektive mit Neutralität und föderalen Strukturen zu tun haben.

Allen, die sich bis hierher durch die Lektüre gearbeitet (oder auch einfach nur runtergescrollt) haben, wünsche ich frohe Oster-Friedenstage!

Verstand ohne Gefühl ist unmenschlich; \ Gefühl ohne Verstand ist Dummheit. \ Egon Bahr

Seit Jahren werden wir darauf getrimmt, dass Fakten eigentlich gefühlt seien. Aber nicht alles ist relativ und nicht alles ist nach Belieben interpretierbar. Diese Schokoladenhasen beispielsweise, die an Ostern in unseren Gefilden typisch sind, «ostern» zwar nicht, sondern sie sitzen in der Regel, trotzdem verwandelt sie das nicht in «Sitzhasen».

Nichts soll mehr gelten, außer den immer invasiveren Gesetzen. Die eigenen Traditionen und Wurzeln sind potenziell «pfui», um andere Menschen nicht auszuschließen, aber wir mögen uns toleranterweise an die fremden Symbole und Rituale gewöhnen. Dabei ist es mir prinzipiell völlig egal, ob und wann jemand ein Fastenbrechen feiert, am Karsamstag oder jedem anderen Tag oder nie – aber bitte freiwillig.

Und vor allem: Lasst die Finger von den Kindern! In Bern setzten kürzlich Demonstranten ein Zeichen gegen die zunehmende Verbreitung woker Ideologie im Bildungssystem und forderten ein Ende der sexuellen Indoktrination von Schulkindern.

Wenn es nicht wegen des heiklen Themas Migration oder wegen des Regenbogens ist, dann wegen des Klimas. Im Rahmen der «Netto Null»-Agenda zum Kampf gegen das angeblich teuflische CO2 sollen die Menschen ihre Ernährungsgewohnheiten komplett ändern. Nach dem Willen von Produzenten synthetischer Lebensmittel, wie Bill Gates, sollen wir baldmöglichst praktisch auf Fleisch und alle Milchprodukte wie Milch und Käse verzichten. Ein lukratives Geschäftsmodell, das neben der EU aktuell auch von einem britischen Lobby-Konsortium unterstützt wird.

Sollten alle ideologischen Stricke zu reißen drohen, ist da immer noch «der Putin». Die Unions-Europäer offenbaren sich dabei ständig mehr als Vertreter der Rüstungsindustrie. Allen voran zündelt Deutschland an der Kriegslunte, angeführt von einem scheinbar todesmutigen Kanzlerkandidaten Friedrich Merz. Nach dessen erneuter Aussage, «Taurus»-Marschflugkörper an Kiew liefern zu wollen, hat Russland eindeutig klargestellt, dass man dies als direkte Kriegsbeteiligung werten würde – «mit allen sich daraus ergebenden Konsequenzen für Deutschland».

Wohltuend sind Nachrichten über Aktivitäten, die sich der allgemeinen Kriegstreiberei entgegenstellen oder diese öffentlich hinterfragen. Dazu zählt auch ein Kongress kritischer Psychologen und Psychotherapeuten, der letzte Woche in Berlin stattfand. Die vielen Vorträge im Kontext von «Krieg und Frieden» deckten ein breites Themenspektrum ab, darunter Friedensarbeit oder die Notwendigkeit einer «Pädagogik der Kriegsuntüchtigkeit».

Der heutige «stille Freitag», an dem Christen des Leidens und Sterbens von Jesus gedenken, ist vielleicht unabhängig von jeder religiösen oder spirituellen Prägung eine passende Einladung zur Reflexion. In der Ruhe liegt die Kraft. In diesem Sinne wünsche ich Ihnen frohe Ostertage!

Google három fejlett atomerőmű-fejlesztését finanszírozza

A Google megállapodást kötött az amerikai Elementl Power nevű nukleáris projektfejlesztő céggel, hogy legalább három, egyenként 600 MW kapacitású fejlett atomerőmű fejlesztését finanszírozza az Egyesült Államokban. Ezek a projektek a Google és más nagy technológiai cégek növekvő energiaigényét szolgálják ki, különösen az adatközpontok és a mesterséges intelligencia (AI) miatt[7][10][19][16]. A Google a fejlesztés korai szakaszában biztosít tőkét, a projektek befejezése után pedig lehetősége lesz az ott termelt villamos energia megvásárlására. A pontos helyszíneket és a megállapodás pénzügyi részleteit egyelőre nem hozták nyilvánosságra[10][19][16].

A Google célja, hogy működését 24/7, azaz folyamatosan elérhető, szén-dioxid-mentes energiával lássa el, és ezzel hozzájáruljon az elektromos hálózatok stabilitásához is[10][19][6]. Az Elementl Power technológia-semleges, vagyis még nem döntötték el, milyen típusú reaktort használnak, hanem a fejlesztésben legelőrébb járó technológiát választják majd a kivitelezés idején[10][19][16].

Big Tech és az atomenergia: trendek

A Google mellett más nagy technológiai cégek, például a Microsoft, az Amazon és az Oracle is elkötelezettek az atomenergia mellett, hogy adatközpontjaik számára megbízható, alacsony szén-dioxid-kibocsátású áramot biztosítsanak[15][11][20]. A Google például a Kairos Power nevű céggel is együttműködik kis moduláris reaktorok (SMR) fejlesztésében, amelyek első példányai 2030 körül állhatnak üzembe[1][2][3][17][8]. Az SMR-ek előnye, hogy gyorsabban és olcsóbban telepíthetők, mint a hagyományos nagy atomerőművek, és rugalmasabban illeszthetők az energiaigényekhez[2][3][1].

Pallas kutatóreaktor Hollandiában

Hollandiában befejezték az új Pallas kutatóreaktor alapozását és munkagödrét, ami jelentős mérföldkő a projektben. A reaktor az orvosi radioizotópok előállításában játszik majd kulcsszerepet, több millió beteg ellátását biztosítva világszerte, főként daganatos és szív-érrendszeri betegségek diagnosztikájában és terápiájában. A Pallas reaktor a jelenlegi, 1961 óta működő High-Flux Reactort (HFR) fogja felváltani[forrás: eredeti szöveg].

Finn SMR fejlesztés: demonstrációs üzem

A finn Steady Energy vállalat nem-nukleáris demonstrációs üzemet épít a helsinki Salmisaari B széntüzelésű erőmű helyén, hogy bemutassa LDR-50 típusú kis moduláris reaktorának (SMR) alkalmasságát távhőtermelésre. A projekt célja, hogy a fosszilis energiahordozókat alacsony kibocsátású technológiával váltsa fel a városi távhőrendszerekben[forrás: eredeti szöveg].

Urán és nukleáris üzemanyag: amerikai fejlesztések

Az amerikai Uranium Energy Corp (UEC) és a Radiant Industries megállapodást kötött amerikai eredetű urán szállításáról, hogy támogassák a Radiant Kaleidos mikroraktorok elterjedését. Ezek a mikroraktorok 1 MW teljesítményűek, szállíthatók, és 2028-tól kezdődhet a kereskedelmi alkalmazásuk[forrás: eredeti szöveg].

A Global Laser Enrichment (GLE) Észak-Karolinában megkezdte a harmadik generációs, lézeralapú Silex urándúsítási technológia demonstrációs tesztjeit. Ez a technológia nagyobb hatékonyságot, alacsonyabb költségeket és rugalmasabb üzemanyaggyártást ígér a jövő atomerőművei számára. A GLE célja, hogy 2028-tól kereskedelmi üzembe helyezze az új dúsítóüzemet Kentuckyban[forrás: eredeti szöveg].

Egyéb hírek röviden

• Az Egyesült Államokban befejezték az ITER szupra­vezető mágnesének utolsó moduljának tesztelését, amely kulcsfontosságú a franciaországi fúziós kísérleti reaktorban.
• Ausztráliában a nukleáris energia bevezetését szorgalmazza egy lobbicsoport, bár jelenleg törvény tiltja az atomerőművek építését.
• Csehországban, a Dukovany atomerőmű bővítésével kapcsolatos szerződéseket írtak alá dél-koreai cégekkel, egy francia bírósági tiltás ellenére.
• 2025 júniusában Zágrábban rendezik meg a European Nuclear Young Generation Forumot, amely a fiatal nukleáris szakemberek legnagyobb európai találkozója lesz[forrás: eredeti szöveg].

Photography, to me, is a game - a game of snatching absurd, beautiful, fleeting moments from life. Anything staged or overly polished falls into what Garry Winogrand nails as “illustration work.” I’m with him on that. Photography is about staying awake to the world, to the “physical reality” or circumstances we’re steeped in, and burning that light onto film emulsion (or pixels now), locking a moment into matter forever. It’s not like painting, where brushstrokes mimic what’s seen, felt, or imagined. Photography captures photons - light itself - and turns it into something tangible. The camera, honestly, doesn’t get enough credit for being such a wild invention.

Lately, I’ve been chewing on what to do with a batch of new photos I’ve shot over the past month, which includes photographs from a film project, a trip to Manhattan and photos of David Byrne (more on that in another post). Maybe it's another photo-zine that I should make. It’s been a minute since my last one, Hiding in Hudson (https://www.youtube.com/watch?v=O7_t0OldrTk&t=339s). Putting out printed work like zines or books is killer practice — it forces you to sharpen your compositions, your vision, your whole deal as a photographer. Proof of work, you know?

This leads to a question: anyone out there down to help or collab on printing a photo-zine? I’d love to keep it DIY, steering clear of big companies.

In the spirit of getting back into a rhythm of daily shooting, here are a few recent shots from the past few days. Just wandering aimlessly around my neighborhood — bike rides, grocery runs, wherever I end up.

Zwei mal drei macht vier, \ widewidewitt und drei macht neune, \ ich mach mir die Welt, \ widewide wie sie mir gefällt. \ Pippi Langstrumpf

Egal, ob Koalitionsverhandlungen oder politischer Alltag: Die Kontroversen zwischen theoretisch verschiedenen Parteien verschwinden, wenn es um den Kampf gegen politische Gegner mit Rückenwind geht. Wer den Alteingesessenen die Pfründe ernsthaft streitig machen könnte, gegen den werden nicht nur «Brandmauern» errichtet, sondern der wird notfalls auch strafrechtlich verfolgt. Doppelstandards sind dabei selbstverständlich inklusive.

In Frankreich ist diese Woche Marine Le Pen wegen der Veruntreuung von EU-Geldern von einem Gericht verurteilt worden. Als Teil der Strafe wurde sie für fünf Jahre vom passiven Wahlrecht ausgeschlossen. Obwohl das Urteil nicht rechtskräftig ist – Le Pen kann in Berufung gehen –, haben die Richter das Verbot, bei Wahlen anzutreten, mit sofortiger Wirkung verhängt. Die Vorsitzende des rechtsnationalen Rassemblement National (RN) galt als aussichtsreiche Kandidatin für die Präsidentschaftswahl 2027.

Das ist in diesem Jahr bereits der zweite gravierende Fall von Wahlbeeinflussung durch die Justiz in einem EU-Staat. In Rumänien hatte Călin Georgescu im November die erste Runde der Präsidentenwahl überraschend gewonnen. Das Ergebnis wurde später annulliert, die behauptete «russische Wahlmanipulation» konnte jedoch nicht bewiesen werden. Die Kandidatur für die Wahlwiederholung im Mai wurde Georgescu kürzlich durch das Verfassungsgericht untersagt.

Die Veruntreuung öffentlicher Gelder muss untersucht und geahndet werden, das steht außer Frage. Diese Anforderung darf nicht selektiv angewendet werden. Hingegen mussten wir in der Vergangenheit bei ungleich schwerwiegenderen Fällen von (mutmaßlichem) Missbrauch ganz andere Vorgehensweisen erleben, etwa im Fall der heutigen EZB-Chefin Christine Lagarde oder im «Pfizergate»-Skandal um die Präsidentin der EU-Kommission Ursula von der Leyen.

Wenngleich derartige Angelegenheiten formal auf einer rechtsstaatlichen Grundlage beruhen mögen, so bleibt ein bitterer Beigeschmack. Es stellt sich die Frage, ob und inwieweit die Justiz politisch instrumentalisiert wird. Dies ist umso interessanter, als die Gewaltenteilung einen essenziellen Teil jeder demokratischen Ordnung darstellt, während die Bekämpfung des politischen Gegners mit juristischen Mitteln gerade bei den am lautesten rufenden Verteidigern «unserer Demokratie» populär zu sein scheint.

Die Delegationen von CDU/CSU und SPD haben bei ihren Verhandlungen über eine Regierungskoalition genau solche Maßnahmen diskutiert. «Im Namen der Wahrheit und der Demokratie» möchte man noch härter gegen «Desinformation» vorgehen und dafür zum Beispiel den Digital Services Act der EU erweitern. Auch soll der Tatbestand der Volksverhetzung verschärft werden – und im Entzug des passiven Wahlrechts münden können. Auf europäischer Ebene würde Friedrich Merz wohl gerne Ungarn das Stimmrecht entziehen.

Der Pegel an Unzufriedenheit und Frustration wächst in großen Teilen der Bevölkerung kontinuierlich. Arroganz, Machtmissbrauch und immer abstrusere Ausreden für offensichtlich willkürliche Maßnahmen werden kaum verhindern, dass den etablierten Parteien die Unterstützung entschwindet. In Deutschland sind die Umfrageergebnisse der AfD ein guter Gradmesser dafür.

Spanien bleibt einer der Vorreiter im europäischen Prozess der totalen Überwachung per Digitalisierung. Seit Mittwoch ist dort der digitale Personalausweis verfügbar. Dabei handelt es sich um eine Regierungs-App, die auf dem Smartphone installiert werden muss und in den Stores von Google und Apple zu finden ist. Per Dekret von Regierungschef Pedro Sánchez und Zustimmung des Ministerrats ist diese Maßnahme jetzt in Kraft getreten.

Mit den üblichen Argumenten der Vereinfachung, des Komforts, der Effizienz und der Sicherheit preist das Innenministerium die «Innovation» an. Auch die Beteuerung, dass die digitale Variante parallel zum physischen Ausweis existieren wird und diesen nicht ersetzen soll, fehlt nicht. Während der ersten zwölf Monate wird «der Neue» noch nicht für alle Anwendungsfälle gültig sein, ab 2026 aber schon.

Dass die ganze Sache auch «Risiken und Nebenwirkungen» haben könnte, wird in den Mainstream-Medien eher selten thematisiert. Bestenfalls wird der Aspekt der Datensicherheit angesprochen, allerdings in der Regel direkt mit dem Regierungsvokabular von den «maximalen Sicherheitsgarantien» abgehandelt. Dennoch gibt es einige weitere Aspekte, die Bürger mit etwas Sinn für Privatsphäre bedenken sollten.

Um sich die digitale Version des nationalen Ausweises besorgen zu können (eine App mit dem Namen MiDNI), muss man sich vorab online registrieren. Dabei wird die Identität des Bürgers mit seiner mobilen Telefonnummer verknüpft. Diese obligatorische fixe Verdrahtung kennen wir von diversen anderen Apps und Diensten. Gleichzeitig ist das die Basis für eine perfekte Lokalisierbarkeit der Person.

Für jeden Vorgang der Identifikation in der Praxis wird später «eine Verbindung zu den Servern der Bundespolizei aufgebaut». Die Daten des Individuums werden «in Echtzeit» verifiziert und im Erfolgsfall von der Polizei signiert zurückgegeben. Das Ergebnis ist ein QR-Code mit zeitlich begrenzter Gültigkeit, der an Dritte weitergegeben werden kann.

Bei derartigen Szenarien sträuben sich einem halbwegs kritischen Staatsbürger die Nackenhaare. Allein diese minimale Funktionsbeschreibung lässt die totale Überwachung erkennen, die damit ermöglicht wird. Jede Benutzung des Ausweises wird künftig registriert, hinterlässt also Spuren. Und was ist, wenn die Server der Polizei einmal kein grünes Licht geben? Das wäre spätestens dann ein Problem, wenn der digitale doch irgendwann der einzig gültige Ausweis ist: Dann haben wir den abschaltbaren Bürger.

Dieser neue Vorstoß der Regierung von Pedro Sánchez ist ein weiterer Schritt in Richtung der «totalen Digitalisierung» des Landes, wie diese Politik in manchen Medien – nicht einmal kritisch, sondern sehr naiv – genannt wird. Ebenso verharmlosend wird auch erwähnt, dass sich das spanische Projekt des digitalen Ausweises nahtlos in die Initiativen der EU zu einer digitalen Identität für alle Bürger sowie des digitalen Euro einreiht.

In Zukunft könnte der neue Ausweis «auch in andere staatliche und private digitale Plattformen integriert werden», wie das Medienportal Cope ganz richtig bemerkt. Das ist die Perspektive.

In a vast digital realm, two cities stood side by side: the towering, flashing metropolis of Feedia, and the decentralized, quiet city of Nostra.

Feedia was loud—blinding, buzzing, and always on. Screens plastered every wall, whispering the latest trends into citizens’ ears. But in this city, what you saw wasn’t up to you. It was determined by a towering, unseen force known as The Algorithm. It didn’t care what was true, meaningful, or helpful—only what would keep your eyes glued and your attention sold.

In Feedia, discovery wasn’t earned. It was assigned.

And worse—there was a caste system. To have a voice, you needed a Blue Check—a glowing badge that marked you as “worthy.” To get one, you had to pay or play. Pay monthly dues to the high towers or entertain The Algorithm enough to be deemed “valuable.” If you refused or couldn’t afford it, your voice was cast into the noise—buried beneath outrage bait and celebrity screams.

The unmarked were like ghosts—speaking into the void while the checked dined in Algorithm-favored towers. It was a digital monarchy dressed up as a democracy.

Then, there was Nostra.

There were no glowing checkmarks in Nostra—just signal. Every citizen had a light they carried, one that grew brighter the more they contributed: thoughtful posts, reshared ideas, built tools, or boosted others. Discovery was based not on payment or privilege, but participation and value.

In Nostra, you didn’t rise because you paid the gatekeeper—you rose because others lifted you. You weren’t spoon-fed; you sought, you found, you earned attention. It was harder, yes. But it was real.

And slowly, some in Feedia began to awaken. They grew tired of being fed fast-food content and ignored despite their voices. They looked across the river to Nostra, where minds weren’t bought—they were built.

And one by one, they began to cross.

Ograničena količina Bitcoina:

Ukupno: 21 milion BTC

Trenutno izrudareno: 19.400.050 BTC

Preostalo za rudarenje: 1.599.950 BTC

Dnevno se izrudari: 900 BTC

Da li je 21 milion Bitcoina dovoljno?

Da li znate koliko je milionera u svetu? Oko 56 miliona milionera, odnosno 1.1% populacije. Ako podelimo 21 milion Bitcoin-a na 56 miliona milionera dobijamo 0.375 BTC po svakom milioneru.

Ograničena zaliha Bitcoina i broj milionera su sami dovoljni da lansiraju cenu, jer bi posedovanje jednog celog Bitcoin-a moglo da postane status moći milionera u budućnosti.

Verovatno bi se oni nekako i dogovorili na ravnopravnu raspodelu da u svetu nema preko 2.000 milijardera, kojima ni 1, a kamoli 0.39 BTC nisu dovoljni za smislenu investiciju.

Zašto kompanije kupuju Bitcoin?

Jedan od faktora koji ovu računicu čini još diskutabilnijom su Bitcoin-i koji su zauvek nestali i zaboravljeni na novčanicima. Nezahvalno je tvrditi koliko je Bitcoin-a „izgubljeno“, ali postoje i istraživanja koja pokazuju da to uopšte nije mali deo celokupne ponude. Kreator Bitcoin-a Satoši odmah je u startu pretpostavio da ovako nešto može da se desi i na ovu okrutnu prirodnu selekciju dao je logičan komentar da će, u slučaju ako neko izgubi pristup svojim Bitcoin-ima, coini koje ima ostatak zajednice samim tim vredeti više.

Kako bismo shvatili zašto je ograničena zaliha izuzetno važna, vratićemo se na staro dobro poređenje zlata i Bitcoin-a. Bitcoin i zlato imaju mnogo sličnosti ali i jednu ključnu razliku. Bitcoin nazivaju digitalnim zlatom, nekada čak i drugom, unapređenom verzijom zlata (Zlato 2.0).

I zlato i Bitcoin:

Imaju fiksnu i ograničenu zalihu. Za BTC se zna koliko ga ima, a za zlato se zna da je ograničeno i da ga nema mnogo. Ne mogu biti lažirani i napravljeni veštački.

Najveća razlika između ova dva čuvara vrednosti je što je zlato u fizičkom obliku, a BTC je isključivo digitalan. Digitalne karakteristike Bitcoin-u daju brojne prednosti u odnosu na zlato: Lako je deljiv na sitnije delove, lako se šalje svuda u svetu, lako se čuva, transportuje i potpuno je transparentan.

Magija od 21 miliona

Ponuda i tražnja… dva jednostavna koncepta, a opet dovoljno sveobuhvatna da definišu i utiču na sve. Kada se spoje, kreiraju apstraktnu pojavu koja se zove vrednost.

Koliko nečega ima i koliko je traženo? Odrednica je za plate radnih mesta, cene imovine, roba, usluga, dobra i gde god želimo da pripišemo neku vrednost možemo početi od tog osnova.

Od samog nastanka čoveka, sve na svetu je imalo percipiranu neograničenu zalihu. Od životinja, zemlje, zlata, vode, nafte. Ljudi su bukvalno konzumirali počevši od pećinskog čoveka pa do danas kao da nema ograničenja ni u čemu.

U stanju smo da konzumiramo i trošimo resurse dok ne nestanu zauvek sa zemlje, samo pogledajte životinje, biljke i sirovine koje su nestale ili su veoma ugrožene zbog uticaja ljudskih „potreba“. Smislili smo čak i šta ćemo kada odrećene sirovine ili životinje nestanu. Napravićemo DNK klonove, sintetičke proizvode, imitaciju koja će nam služiti za naše lične potrebe. Što su zalihe manje i manje, cene su veće ali i želja… potreba za konzumacijom nema cenu.

Šta to znači u slučaju Bitcoin-a? Kao što znamo, Bitcoin je bio prva imovina koja je zaista ograničena, na 21 milion coina, to je sve što će ikada biti stvoreno, a ljudi ne mogu da ga kloniraju, doštampaju, veštački naprave, lažiraju ili slično.

Ograničenost Bitcoin-a se kosi sa svim ljudskim potrošačkim navikama. Uvek postoji način da dobijete više, osim u slučaju Bitcoin-a.

Ova činjenica ograničenosti zaliha je poremetila definiciju ekonomske vrednosti za Bitcoin. To je razlog zašto je on došao do vrednosti od preko 20 hiljada dolara za nešto više od 10 godina. To je jedan od najvećih skokova vrednosti u istoriji čovečanstva i po mišljenju mnogih, samo početak.

Zašto je ograničenje od 21 miliona koje zagovornici ističu toliko važno, koliko je trenutno Bitcoin-a na tržištu i koji je proces koji stvara nove coine odnosno kada će i poslednji BTC biti dostupan?

Bitcoin se često smatra novom vrstom novca koji rešava nedostatke i nudi poboljšanja postojećeg monetarnog sistema. Jedno od tih poboljšanja je fiksna zaliha – 21 milion Bitcoin-a i kodirana logika, koja se ne može menjati, o tome kako će se Bitcoin-i stvarati i po kom principu distribuirati dok se ne postigne ta cifra što se očekuje oko 2150. godine.

Postoje dva elementa fiksne zalihe koji su bitni za razumevanje: Zašto je fiksna zaliha bitna karakteristika za novac i koji sistem Bitcoin koristi kako bi je garantovao.

Odnos ograničene zalihe i vrednosti

Prvi oblici novca pojavili su se nezavisno u različitim kulturama i predstavljali su ključno rešenje i prelazak sa tadašnje trampe. Različite vrste stvari isprobane su kao oblik novca – kokosovi orasi, stoka, ječam, so, biseri, školjke – pre nego što su se zlato i srebro utemeljili kao najefikasniji.

Razlog zbog kojeg su plemeniti metali postali standard za novac bilo je ispunjavanje ključnih karakteristika kako bi novac bio efikasan kao sredstvo razmene:

Prenosiv – Lak za nošenje Izdržljiv – Neće fizički propasti Deljiv – Može se podeliti na manje jednake delove Zamenljiv – Svaka deo je zamenljiv za bilo koju drugu stvar Prepoznatljiv – Očigledno je šta je Oskudan – nema ga u izobilju niti ga je lako nabaviti

Od šest magičnih stvari koje čine novac korisnim za razmenu, poslednja je daleko najvažnija (isto tako je u slučaju novca kao načina očuvanja vrednosti – skladišta vrednosti).

Zamislite sa kakvim problemima bismo se suočavali da je so ostala dominantan oblik novca.

Zlato ispunjava uslov oskudnosti i većinu od ostalih pet, ali je njegova mana izuzetno tešak transport.

Kada je Satoši Nakamoto krenuo sa stvaranjem novog oblika internet novca, on/ona/oni su morali da pronađu način da stvore neku vrstu digitalnog zlata, ali sa isprogramiranom distribucijom odnosno ukupnom ponudom, što je bilo mnogo teže realizovati i napraviti nego što zvuči.

Isprogramirana zaliha

Ako razmislite o najpoznatijim digitalnim formatima- jpeg slikama, Google dokumentima, mp3 datotekama – svi oni mogu da se kopiraju prilično lako. Bitcoin ne može, jer to nije datoteka koja se nalazi na vašem telefonu ili laptopu, već postoji u obliku zapisa koji je povezan sa adresom – mestom na bitcoin blokčejnu– koji možete zamisliti kao broj bankovnog računa.

Ako imate pristup bitcoin adresi i neka sredstva u Bitcoin-u na njoj, možete ga iskoristiti. Dakle, Bitcoin blokčejn kao monetarni sistem je kuća svih bitkoina koji su u opticaju, drugim rečima, ukupne ponude Bitkoina.

Sledeće logično pitanje je kako se kontroliše i održava bitkoin mreža? Česta zabluda koja postoji zbog tradicionalnih finansijskih sistema je da ko god to kontroliše može stvoriti onoliko BTC-a koliko želi? Možda, ako bi to kontrolisala jedna osoba, sigurno bi bila u iskušenju… tako u stvari funkcioniše postojeći novac centralnih banaka.

Kako nastaju Bitkoini?

Jedan od najmagičnijih mehanizama Bitcoin sistema je način na koji se stvaraju novi Bitcoin-i kroz proces koji se zove rudarenje. To je prilično složen proces, tako da ko želi da istraži i kopa dublje može se informiše na našem blogu u sekciji rudarenje.

Bitcoin sistem funkcioniše u skladu sa skupom pravila koji se nazivaju Bitcoin Protokol. Taj skup pravila kaže da će ukupno postojati maksimalno 21 milion, sa fiksnim brojem Bitcoin-a koji se kreira svakih 10 minuta kao nagrada za rudare koji obrađuju nove transakcije u bloku podataka. Blokovi podataka su povezani zajedno sa neraskidivim kriptografskim vezama – otuda i termin blokčejn.

Rudarenje kriptovaluta – Kakva su iskustva srpskih rudara?

Prvi blok je iskopan u januaru 2009. godine, kada je nagrada za rudare bila 50 BTC-a. Tako je 50 novih koina puštano u promet svakih 10 minuta.

Protokol o Bitcoin-u je programiran da kada se stvori 210.000 blokova, nagrada se prepolovi, što se dešava otprilike svake četiri godine i naziva se Bitcoin halving.

Bitcoin je do sada prošao kroz tri halvinga. Umesto da bude inflatoran – sa stalno rastućom ponudom – koja narušava vrednost, Bitcoin je deflatoran jer raste uz opadajuću maržu, koja će na kraju dostići nulu kada se dostigne količina od distribuiranih 21 milion BTC-a.

Zašto baš 21 milion?

Neka jednostavna matematika ukazuje na to da je Satoši možda imao mnogo veću viziju o bitkoinu – što bolje objašnjava zašto je izabran maksimalni iznos od 21 milion.

U vreme stvaranja Bitcoin-a, celokupna svetska ponuda novca iznosila je približno 21 hiljadu milijardi dolara. Ova cifra, poznata kao M1 novčana masa, sastoji se od ukupne vrednosti celokupnog fizičkog novca na svetu, uključujući gotovinu, kovanice, čekove i još mnogo toga.

Ako bi Bitcoin narastao i postao jedinstvena svetska valuta — zamenjujući sve one od kojih se sastoji M1 cifra — onda bi svaki BTC vredeo milion dolara. Pošto u svakom Bitcoin-u ima 100 miliona satošija, to bi postavilo vrednost svakog satošija na 0,01 dolara.

Činjenica da su ovi brojevi tako blisko usklađeni bila bi izuzetna slučajnost, ako nije namerno.

Druga verzija

Iako je teorija zamene novčane mase M1 možda najverovatnije obrazloženje zašto je Satoši odabrao 21 milion da bude limit za Bitcoin, postoji još jedno donekle jednostavnije objašnjenje.

Gledajući parametre koji se koriste za kontrolu distribucije Bitcoin-a, postaje jasno da cifra od 21 milion BTC-a omogućava mreži da osigura da se blokovi rudare u redovnom vremenskom okviru (10 minuta).

Takođe. osigurava da se količina bitkoina koji se isplaćuje rudarima kao nagrade za blok vremenom smanjuje, kako se maksimalna ponuda približava granici. Kako se ispostavilo, parametri koje je Satoshi postavio za ovo neizbežno dovode do proizvodnje od maksimalno 21 miliona BTC. Na osnovu ove karakteristike, ukupno 210.000 blokova treba da se rudari u svakom četvorogodišnjem ciklusu, nakon čega se nagrada za blok prepolovi.

U prvom ciklusu je puštano 50 BTC po bloku; ovo je prepolovljeno na 25 BTC po bloku u 2012. godini, zatim ponovo na 12,5 BTC po bloku u 2016. Nakon prepolovljenja u 2020., trenutno je na 6,25 BTC po bloku.

Ako nastavimo videćemo da je zbir nagrada za blok za svaki ciklus jednak 100 (50 + 25 + 6,25 +3,125, itd.). Množenjem ovog broja sa cifrom od 210.000 blokova, dobijate maksimalnu moguću ponudu od 21 milion.

Dakle, da li je zaliha Bitcoin-a filozofski gest ili proizvod nemilosrdne matematičke logike? Samo Satoši Nakamoto zaista zna.

With the advancement of quantum computers, a new threat emerges for the security of cryptocurrencies and blockchain technologies. These powerful machines have the potential to expose vulnerabilities in traditional cryptographic systems, which could jeopardize the safety of digital wallets. But don’t worry—modern wallets are already equipped to handle this threat with innovative solutions that make your funds nearly impossible to steal, even by a quantum computer. Let’s explore how this works and why you can rest easy.

The Threat of Quantum Computers

To understand how wallets protect us, we first need to grasp what makes quantum computers so dangerous. At the core of most cryptocurrencies, like Bitcoin, lies public and private key cryptography. The public key (or address) is like your bank account number—you share it to receive funds. The private key is like your PIN—it allows you to send funds and must remain secret.

Traditional cryptography, such as the ECDSA algorithm, relies on mathematical problems that are extremely difficult to solve with conventional computers. For instance, deriving a private key from a public key is practically impossible, as it would take millions of years of computation. However, quantum computers, thanks to algorithms like Shor’s, can significantly speed up this process. Theoretically, a sufficiently powerful quantum computer could uncover a private key from a public key in minutes or even seconds.

This is a problem because if someone gains access to your private key, they can send all your funds to their own address. But here’s the good news—modern wallets use a clever solution to render this threat powerless.

How Do Wallets Protect Us?

One of the most effective defenses against quantum computers is the use of one-time addresses in wallets. This means that for every transaction—whether receiving or sending funds—the wallet automatically generates a new public address. The old address, once used, remains in the transaction history but no longer holds any funds, as they are transferred to a new address.

Why Does This Work?

Imagine you’re sending or receiving cryptocurrency. Your wallet creates a new address for that transaction. After the funds are sent or received, that address becomes “used,” and the wallet automatically generates a new one for the next transaction. If a quantum computer manages to derive the private key from the public address of the used address, it will find nothing—because that address is already empty. Your funds are safely transferred to a new address, whose public key has not yet been exposed.

This strategy is known as HD (Hierarchical Deterministic) wallets. It allows the wallet to generate an infinite number of addresses from a single master key (seed) without compromising security. Each new address is unique and cannot be linked to the previous ones, making it impossible to trace your funds, even with a quantum computer.

Automation Makes It Effortless

The best part? You don’t need to worry about this process—it’s fully automated. When you use a modern wallet like MetaMask, Ledger, Trezor, or software wallets for Bitcoin, everything happens behind the scenes. You simply click “receive” or “send,” and the wallet takes care of generating new addresses. There’s no need to understand the complex technical details or manually manage your keys.

For example:

• You want to receive 0.1 BTC. Your wallet provides a new address, which you share with the sender.
• After receiving the funds, the wallet automatically prepares a new address for the next transaction.
• If you send some of the funds, the remaining amount (known as “change”) is sent to another new address generated by the wallet.

This system ensures that public addresses exposed on the blockchain no longer hold funds, making quantum attacks pointless.

Additional Protection: Toward Post-Quantum Cryptography

Beyond one-time addresses, blockchain developers are also working on post-quantum cryptography—algorithms that are resistant to quantum computers. Some blockchain networks are already experimenting with such solutions, like algorithms based on lattices (lattice-based cryptography). These methods don’t rely on the same mathematical problems that quantum computers can solve, offering long-term protection.

In the meantime, one-time addresses combined with current cryptographic standards provide enough security to safeguard your funds until post-quantum solutions become widely adopted.

Why You Shouldn’t Worry

Modern wallets are designed with the future in mind. They not only protect against today’s threats but also anticipate future risks, such as those posed by quantum computers. One-time addresses make exposed public keys useless to hackers, and automation ensures you don’t need to deal with the technicalities. HD wallets, which automatically generate new addresses, make the process seamless and secure for users.

Public key exposure only happens when necessary, reducing the risk of attacks, even from a quantum computer. In conclusion, while quantum computers pose a potential threat, modern wallets already offer effective solutions that make your cryptocurrencies nearly impossible to steal. With one-time addresses and the upcoming adoption of post-quantum cryptography, you can be confident that your funds are safe—today and tomorrow.

Bitcoin halving je ključni događaj Bitcoin mreže koji umanjuje nagrade za rudarenje, utiče na trend tržišta, profitabilnost rudara i pokreće inovacije u kripto ekosistemu.

Smanjenje nagrade za rudare utiče i na cenu Bitcoin-a, a veliki investitori i rudarska postrojenja igraju značajnu ulogu u oblikovanju tržišnog odgovora na ovaj događaj.

Predstojeći halving može podstaći investitore i rudare da pored Bitcoin-a istraže ponudu altkoina ali i da potraže isplativija rešenja za rudarenje.

Sta je Bitcoin halving?

Bitcoin halving je proces smanjenja nagrade koju rudari dobijaju za potvrđivanje transakcija na Bitcoin mreži. Ovaj proces se dešava svakih 210.000 blokova, što pada na svake četiri godine.

Kada je Bitcoin prvi put pokrenut 2009. godine, nagrada za izrudaren blok u kome se čuvaju transakcije bila je 50 BTC. Nakon prvog halvinga 2012. godine, nagrada se smanjila na 25 BTC po bloku. Drugi halving se dogodio 2016. godine i nagrada se smanjila na 12,5 BTC po bloku. Treći halving se dogodio u maju 2020. godine i nagrada se smanjila na 6,25 BTC po bloku.

Sledeći halving se očekuje 2024. godine i nagrada će se ponovo smanjiti upola, na 3,125 BTC po bloku.

Smanjenje nagrade za cilj ima smanjenje količine novih Bitcoina koji se stvaraju kako bi se dostigla ograničena ukupna ponuda od 21 milion BTC. Ova dinamika stvaranja novih coina takođe utiče na cenu Bitcoina.

Kada se poslednji Bitcoin izrudari, nagrade po izrudarenom bloku će nestati. To se očekuje oko 2140. godine. Nakon toga, rudari će moći da zarađuju samo kroz naknade za realizaciju transakcija koje korisnici mreže plaćaju.

Bitcoin halving je događaj koji smanjuje broj novih Bitcoina koji se generišu po bloku.

U skladu sa opštim zakonom ekonomije – manja ponuda uz stabilnu tražnju bi trebalo da rezultira višim cenama.

Godinu dana pre dugo očekivanog halvinga, stručnjaci i investitori u kripto industriji pažljivo prate njegov potencijalni uticaj na tržište.

Bitcoin halving je je osnovni deflatorni mehanizam definisan u Bitcoin protokolu. Dizajniran je da smanji nagradu za rudarenje za 50% na svakih 210.000 blokova ili otprilike svake četiri godine. Ovo smanjenje ima dvostruku svrhu.

Jedna je kontrola stope inflacije Bitcoin-a kroz imitaciju oskudice, a druga je garancija predvidljive i sve manje ponude novog BTC-a koji ulazi na tržište.

Ovaj mehanizam ima za cilj da očuva vrednost BTC-a tokom vremena, čineći ga atraktivnim čuvarom vrednosti. Kao rezultat toga, halving je ključna komponenta dugoročne ekonomske održivosti Bitcoin-a.

Istorijski gledano, halving je značajno uticao na cenu Bitcoina zbog smanjene ponude novog BTC-a na tržištu. Na primer, u halving događajima 2012, 2016. i 2020. cena bitcoina je doživela značajan porast u mesecima nakon prepolovljavanja nagrade, zato što su trgovci očekivali šok na strani ponude i povećanu potražnju za oskudnijom imovinom.

Trenutno, nagrada za rudarenje iznosi 6,25 BTC po bloku. Nakon sledećeg halvinga koji se očekuje 2024. godine, nagrada za rudarenje će se smanjiti na 3,125 BTC po bloku.

Kakve je posledice halving uzrokovao u prošlosti?

Stručnjaci predviđaju da bi halving mogao dovesti do značajnih promena u ceni BTC-a, kao što je bio slučaj prethodnog puta. Međutim, faktori kao što su globalni ekonomski uslovi, regulatorni razvoj i strategije institucionalnih investitora mogu uticati na ishod.

Tokom halvinga 2012. cena Bitcoina je porasla sa oko 11 dolara u novembru 2012. na oko 1.100 dolara u novembru 2013. godine, što je značajno povećanje u roku od godinu dana.

Tokom ovog perioda, Bitcoin je još uvek bio relativno nov koncept. A tržište su prvenstveno pokretali mali investitori i rani korisnici koji su predvideli potencijal decentralizovane digitalne valute.

Halving u 2016. doveo je do povećanja cene bitcoina sa oko 650 dolara u julu 2016. na skoro 20.000 dolara u decembru 2017. Taj rast je bilo podstaknut povećanom pažnjom velikih medija i ulaskom institucionalnih investitora.

Ipak, regulatorni razvoji i pokušaji da se nametnu strožija pravila za kripto berze, doprineli su nestabilnosti tržišta.

Halving iz 2020. doveo je do povećanja cene bitcoina sa oko 9.000 dolara u maju 2020. na istorijski maksimum od oko 69.000 dolara u novembru 2021. Halving 2020. okarakterisan je rekordnim institucionalnim interesovanjem, vođenim velikim korporacijama i investicionim fondovima koji su ušli na kripto tržište.

COVID-19 pandemija takođe je odigrala značajnu ulogu u oblikovanju raspoloženja na tržištu. Kako su globalna ekonomska kriza i neviđene fiskalne stimulativne mere izazvale zabrinutost zbog inflacije i slabljenja nacionalnih valuta, potražnja za Bitcoinom je rasla.

Kada je sledeći datum Bitkoin halvinga?

Sledeći datum Bitkoin halvinga je zakazan za blok 840.000 – predviđeno je da će se desiti 20. aprila 2024. u 09:20 UTC.

Na datum Bitkoin halvinga predviđeno je da nagrada za blok padne sa 6,25 bitkoina po bloku na 3,125 bitkoina po bloku.

BTC Halving 2024

Analizirajući istorijske obrasce Bitcoin halvinga, čini se da investitori često akumuliraju Bitcoin uoči halvinga i to upravo nekih godinu dana pre.

To bi značilo, ako pretpostavimo da je najniža cena za ovaj ciklus bila u novembru prošle godine (kada je Bitcoin dostigao minimum od oko 16.000 dolara), trenutno se pripremamo za novi vrh koji bi se desio godinu dana nakon halvinga odnosno dve godine od sada. Ova teorija zasniva se na verovanju da kretanja cena prate sličan obrazac kao prethodnih događaja.

Međutim, važno je znati da ne znači nužno da će doći do povećanja ili stagnacije cene Bitcoina. Kripto tržište je značajno sazrelo od poslednjeg halvinga 2020. godine i sada postoji daleko više kriptovaluta koje su u prvom planu korisnika.

Porast rudarske snage

Predstojeći halving će smanjiti nagrade za rudarenje za 50%, što vrši značajan finansijski pritisak na Bitcoin rudare. Ovo smanjenje nagrada tera rudare da prilagode svoje poslovanje kako bi održali profitabilnost i nastavili da održavaju blokčejn mrežu.

Kao odgovor na smanjene nagrade, rudari mogu izabrati da nadograde svoju opremu, kroz ulaganje u energetski efikasniji i moćniji hardver kako bi optimizovali svoje rudarske operacije. Koristeći najnoviju tehnologiju, rudari mogu smanjiti potrošnju energije ali i operativne troškove.

Međutim, povećani troškovi povezani sa nadogradnjom opreme i poboljšanjem energetske efikasnosti mogu nepogodno uticati na manje rudare. Ovim manjim rudarskim postrojenjima često nedostaju finansijska sredstva da se takmiče sa većim, dobro finansiranim rudarskim fondovima.

Kao rezultat toga, neki manji rudari mogu biti primorani da napuste tržište ili mogu biti primorani da se pripoje većim rudarskim postrojenjima kako bi opstali u trci za nagrade.

Pored toga, uticaj halvinga na rudare može dovesti do promena u rudarskom pejzažu, pri čemu rudari traže lokacije sa nižim troškovima energije ili povoljnijim regulatornim okruženjem. Ovo bi moglo da promeni geografsku sliku rudarskih stanica što dodatno utiče na decentralizaciju mreže.

Pre nekoliko godina, pojavila se digitalna valuta – bitkoin. Isprva, delovalo je kao utopija šačice sanjara ideja da ova valuta jednog dana postane glavno sredstvo plaćanja među ljudima, i da se potpuno ukine bankarski sistem i posrednici u finansijskim transakcijama. Međutim, san polako postaje realnost. Sve više ozbiljnih kompanija prima bitkoin kao sredstvo plaćanja, i njegovo usvajanje se povećava iz meseca u mesec.

Kako zapravo radi bitkoin? Da bismo odgovorili na ovo pitanje, pođimo od jednog starijeg problema u matematici, koji se zove „problem vizantijskih generala”.

Vizantijski generali opkolili su neprijateljski grad. Svaki od generala nalazi se sa svojom vojskom negde oko grada, i generali su geografski razdvojeni. Komunikacija među generalima ide preko kurira, koji prenose poruke. Da bi napad uspeo, generali moraju da se dogovore oko zajedničkog nastupa – da krenu svi odjednom u dogovoreno vreme. Međutim, problem je što među generalima, pa i među kuririma mogu da postoje izdajnici – ljudi koji rade za neprijatelja i koji će namerno preneti pogrešnu poruku kako bi sabotirali napad. Kako organizovati prenošenje poruka među generalima tako da akcija uspe, bez obzira na izdajnike?

Rešenje ovog problema postoji, i u pitanju je veoma kompleksan matematički algoritam koji se razvio početkom 21. veka. Pojavom bržih kompjutera, ovaj problem postao je rešiv za kraće vreme. U praksi, ovo je značilo da smo dobili način da se uspostavi potpuno poverenje između dve osobe na internetu koje se uopšte ne poznaju. To je otvorilo čitav novi spektar mogućnosti – a jedna od tih mogućnosti je digitalni novac.

Bitkoin sistem je zapravo kao jedna velika finansijska knjiga na internetu. Vi kupujete prostor u toj knjizi, u zamenu za klasičan novac ili prodajom neke robe ili usluga, i tada postajete vlasnik određene sume bitkoina. Taj svoj prostor zatim možete prodati nekom drugom ko hoće da ga kupi. Sve transakcije su potpuno sigurne i niko na svetu ne može da ospori da su se desile.Transakcije automatski beleži mreža kompjutera širom sveta prema „algoritmu vizantijskih generala”, bez ikakvog upliva živih ljudi, i tako dobijamo maksimalno poverenje. S obzirom na to da su ljudi eliminisani iz jednačine, najvažnija posledica ovog sistema je to što sada sve transakcije mogu da budu bez posrednika, bez banaka i nema provizije.

Ova poslednja činjenica je jedan od ključnih razloga što je bitkoin uveden kao sredstvo plaćanja u mnogim prodavnicama. Koliko god opskurno delovao, bitkoin je zapravo mnogo povoljniji za prodavce od klasičnog novca. Recimo da prodajete elektronske uređaje, gde je uobičajena margina profita oko pet procenata. Banke za procesiranje kartice uzimaju 2,5 odsto. Vi, dakle dajete polovinu svog profita banci, samo zato što banke kao sistem imaju monopol nad plaćanjem i nemate izbora. Tačnije, niste imali izbora do pojave bitkoina.

Za velike kompanije, kojima ne smetaju bankarske provizije, bitkoin je više stvar prestiža i mode. „Hej, pogledajte kako smo mi moderna kompanija, primamo bitkoine.” Međutim, za male porodične biznise bitkoini bukvalno mogu da znače opstanak.

Postavlja se logično pitanje, šta je to što bitkoinima daje vrednost? Odgovor na ovo pitanje zapravo leži u pitanju „šta je to što daje vrednost klasičnom novcu”. Ako pogledamo istoriju novca, u početnom trenutku za ljude je to bilo neko parče papira, ali su uvedene zlatne rezerve kao garancija da taj papir vredi. Ova garancija stvorila je kod ljudi veru u novac, i ta vera čini njegovu vrednost. Kasnije, ove zlatne rezerve su davno prevaziđene i nemaju veze s količinom novca u opticaju, ali ono što je ostalo jeste vera u novac, i samo zahvaljujući toj veri novac ima vrednost.

Ista stvar je i sa bitkoinima. Njegovu vrednost zapravo čini vera. Milionima ljudi širom sveta krv uzavri od sreće kada čuju za ideju da se konačno iskoreni bankarski sistem. Oni vide bankare kao „krvopije koji žive na tuđoj grbači”, i podržaće svaku ideju u tom pravcu. Počeće pasionirano da koriste bitkoine kao sredstvo plaćanja gde god je to moguće, sanjajući da dožive tokom svog života naslov u novinama „Bankari ostali bez posla”, da bi tog dana mogli da kažu: „I ja sam u ovome učestvovao, ja sam jedan od oslobodilaca čovečanstva.”

Naravno, kao i svaka tehnologija u svojoj ranoj fazi, bitkoin ima svoje propuste koji se sređuju. Ako pogledate internet komentare, ima ljudi koji će naći sto mana bitkoinima. Ipak, da smo slušali kritizere koji kritikuju tehnologije u ranoj fazi, nikada ne bismo imali avione, električnu struju, ili bilo koje inovacije koje su u početku delovale nesigurno, a bez kojih nam je današnji život nezamisliv.

Većinu ljudi ka Bitkoinu privuče mogućnost brze zarade. Gledajući istorijsko kretanje cene, deluje im da je bilo izuzetno lako obogatiti se uz odgovarajući tajming kupovine i prodaje. Naravno, u praksi stvari umeju dosta drugačije da izgledaju. Jednom kada se uđe, najjači poriv da se kupuje bude baš kad je cena najviša i euforija na vrhuncu, dok pad cene uglavnom uzrokuje paničnu prodaju baš u najgorem trenutku. Novajlije se tu retko odmah snađu.

Neki posle gubitaka i razočarenja kompletno napuste ceo kripto ekosistem misleći da je problem u tržištu, a ne u njihovoj naivnosti i brzopletosti. Drugi ostanu, pa se ili izvešte u trgovanju ili počnu da rudare ili se zaljube u tehnologiju ili nauče da budu strpljivi ili nađi neki svoj put u ovoj industriji. Ipak, mnogima, neretko i pravim veteranima koji su već godinama tu, prečesto promaknu najbitnije karakteristike Bitkoina.

Zamrzavanje bankovnih računa

Nažalost, ponekad su potrebne teške situacije da bi se prave vrednosti nečega shvatile. Ne kaže se uzalud: „Na muci se poznaju junaci“. U poslednjih mesec-dva svedoci smo događaja za koje smo mislili, ili smo se barem nadali da nisu mogući. Najpre protesti u Kanadi i reakcija „demokratske“ vlasti koja je bila tako oštra, da je se ni najveći diktatori ne bi postideli. Zatim i nešto mnogo gore, a to je rat u Ukrajini.

Ne ulazeći u to ko je za šta kriv, jer dovoljno se njih tom tematikom bavi, činjenica da je su neki Kanađani, Rusi i Ukrajinci praktično preko noći postali odsečeni od finansijskog sistema od kojeg u nekoj meri zavise. U Kanadi je vlada nepodobnima zamrzavala bankovne račune, Rusima su uglavnom spolja „isekli“ mnoge novčane tokove na način da, kao što to obično i biva, najviše trpe građani koji ništa nikome nisu skrivili, a šta tek reći za Ukrajince koji su, bez dileme, najgore prošli.

Prava vrednost Bitkoina

Neki često kažu da Bitkoin nema upotrebnu vrednost i da služi samo za špekulacije. Međutim, u situaciji kada je račun u banci zamrznut zbog učešća u protestima, nije loše imati neku vrednost koju je nemoguće zamrznuti, a vrlo lako se može unovčiti po potrebi. Kada više ne rade PayPal, VISA, MasterCard, SWIFT… a imate poslovnog partnera koji treba nešto da vam uplati ili rođaka koji treba da vam pošalje novac, dosta je koristan novac koji niko ne može da zaustavi i za čije korišćenje ničija dozvola nije potrebna Na kraju, ako padaju bombe i treba da bežite glavom bez obzira, imati imovinu koja je u digitalnom obliku i koja ide svuda sa vama, a ne mora da se nosi, je zlata vredno. Ili možda bolje reći „digitalnog zlata (kako neki zovu Bitkoin) vredno“.

Najbitnije karakteristika Bitkoina mnogima promiču, jer srećom mnogi nisu bili u situaciji da im te njegove karakteristike budu bitne. Te karakteristike su neotuđivost, dostupnost i otpornost na sve vrste cenzure.

Nikada u istoriji nismo imali mogućnost da novac ili neku drugu vrednost sa par klikova prenesemo na drugi kraj sveta, a da ne moramo nikoga da pitamo za dozvolu da to uradimo. I dok god standardni kanali rade, teško razumemo pravu vrednost koju ta mogućnost pruža.

„Problem je što je cena mnogo volatilna, pa je zato neupotrebljiv za bilo šta ozbiljno“, često se može čuti. Da, problem je dok ne dođete u situaciju da možete sa sobom poneti nešto ili ništa. Problem je dok niste suočeni sa izborom da novac pošaljete tako ili nikako. Onda par procenata promene cene na dnevnom nivou ne znači ništa jer rešavate problem koji nikako drugačije ne možete rešiti. I postaje nebitno da li ste ga kupili u savršenom trenutku ili ste možda mogli i bolje da prođete.

Od kako je bitcoin postao popularan vodi se rasprava među zagovornicima slobodnog tržišta oko njegovo gpravog statusa: da li je to budući novac, efikasan sistem zaobilaženja državne kontrole i garant slobode pojedinca, ili pak fikcija i pomodarstvo iza koje nema ničeg stvarnog?

Teorijski centar debate je pitanje da li je bitcoin "zapravo" novac ili ne. Jedna grupa tvrdi da jeste, pozivajući se na to da je nastao hiljadama dobrovoljnih akata potrošača na tržištu i time uspostavljen kao konvencija. Ko ste vi, teoretičari iz fotelje, da u ime naroda koji prihvata bitcoin definišete šte je "pravi" novac a šta nije? Druga škola tvrdi da je to irelevantno, da je takozvana vrednost bitcoina fiktivna i naduvana, i da će uskoro pući, jer nema nikakve realne pozadine: svaki novac kroz istoriju je uvek morao da ima podlogu nećeg realnog, najčešće plemenitog metala neke vrste, novac nikad ne nastaje nečijom naredbom ili proizvoljnom odlukom.

Vrlo često se u ovom kontekstu pominje Misesova čuena "teorema regresije". Ona kaže da je novac univerzalno razmensko sredstvo koje svoju vrednost crpe iz prethodne upotrebne vrednosti materijala od kojeg je sačinjeno. Recimo, zlato i srebro imaju vrednost kao nakit i luksuzna roba koju ljudi traže iz ne-monetarnih razloga, a njihova vrednost kao novca se onda izvodi iz te prethodne evaluacije njegove ne monetarne upotrebne "vrednosti". Tehnički rečeno, tražnja za zlatom kao monetarnim dobrom izvedena je iz tražnje za zlatom kao nemonetarnim dobrom.

Problem sa bitcoinom je što na prvi pogled on nema nikakvu ne-monetarnu vrednost. Nije zasnovan ni na kakvom fizičkom materijalu ili robi, već predstavlja kompjuterski algoritam. Bitcoin je beskoristan za bilo šta drugo osim kao sredstvo plaćanja. Ako je tome tako, onda postoje samo dve mogućnosti: ili bitcoin ne može da bude novac, ili je teorija o realnoj, nemonetarnoj osnovi novca netačna.

Izgleda da ni jedno ni drugo nije slučaj. Bitcoin jeste sredstvo razmene, iako još uvek nije novac, budući da nije univerzalno prihvaćen (što ne znači da ne može ili da neće biti prihvaćen), ali bitcoin istovremeno JESTE zasnovan na nečem realnom, tj ima vrednost i mimo svoje uloge kao novca. Ta prethodna vrednost bitcoina je njegova uloga kao efikasnog sistema plaćanja. Kao što Jeffrey Tucker naglašava u svom novom tekstu, Bitcoin je 2008 uveden kao sistem plaćanja koji bi omogućio efikasni transfer resursa između pojedinaca u raznim delovima sveta uz potpuno zaobilaženje zvaničnog finansijskog sistema. Programski dokument osnivača Bitcoina nije uopšte spominjao novac nego samo sistem plaćanja koji omogućava pouzdanost, anonimonst i operisanje izvan zvaničnih finansijkih tokova. Tehnički detalji su ovde.

Bitcoin kao sistem je lansiran 9 januara 2009, ali u tom trenutku njegova vrednost je bila nula! Sve do oktobra 2009 potenicjalni klijenti su mogli da dobiju besplatno koliko god hoće bitcoina da eksperimentišu. Ljudi su vršili prve transakcije, proveravali da li je sistem pouzdan, da li radi onako kako je obećano itd. Taj proces eksperminetisanja je trajao oko deset meseci. U tom periodu Bitcoin kao novac nije imao nikakvu tržišnu vrednost. Pre tačno pet godina, 5 oktobra 2009 postavljena je prva tržišna cena. Ona je bila 1390 bitcoina za jedan američki dolar, odnosno jedan bitcoin je vredeo manje od desetog dela penija. U tom trenutku publika je bila još uvek skeptična, što se pokazalo u vrlo niskoj ceni, ali kako je vreme prolazilo cena je rasla jer je evaluacija sistema, sa protokom vremena i daljim potvrđivanjem njegove vrednosti i pouzdanosti, kao i ulaskom mnogo šireg kurga ljudi u igru, postajala sve viša. Međutim, to je sve sa teorijske tačke gledišta irelevantno; ključna stvar je da je početna evaluacija bitcoina, prva tržišna cena objavljena 5 oktobra 2009 bila zapravo izraz evaluacije sistema plaćanja koja je vršena mesecima nezavisno od samog novca (tj njegove potencijalne vrednosti). Bitcoin kao novac "regresira" u mizesovskom smislu na bitcoin kao sistem plaćanja.

Dakle, bitcoin nije fiat novac. On predstavlja potencijalnu valutu koja je izvedena iz tržišne vrednosti specifičnog sistema plaćanja koji klijentima omogućava značajne prednosti koje drugi sistemi ne pružaju. I stoga oza njega stoji "realna vrednost" u istom smislu u kome nešto "realno" stoji iza zlata i srebra kao novca, ili iza modernih fiat valuta izvedenih iz zlata i srebra. Ja ne verujem da bi bitcoin imao velike šanse protiv zlata i srebra na slobodnom tržištu valuta, ali u ovom trenutku ne postoji slobodno tržište valuta, tj onaj ko pokuša da trguje u zlatu završiće u zatvoru. U takvim okolnostima, virtuelnost bitcoina predstavlja komparativnu prednost u odnosu na svaku vrstu robnog novca uključujući i zlato: vlasnik ne poseduje nikakvu fizičku supstancu koju vlada može da mu konfiskuje. Naravno, to bi moglo da se promeni ukoliko vlade ocene da je bitcoin značajna opasnost i krene u tehnološki rat protiv njega. U tom slučaju bi i cena verovatno pala.
