Bank run on every crypto bank then bank run on every "real" bank.

— ODELL (@ODELL) December 14, 2022

Good morning.

It looks like PacWest will fail today. It will be both the fifth largest bank failure in US history and the sixth major bank to fail this year. It will likely get purchased by one of the big four banks in a government orchestrated sale.  

March 8th - Silvergate Bank
March 10th - Silicon Valley Bank
March 12th - Signature Bank
March 19th - Credit Suisse
May 1st - First Republic Bank
May 4th - PacWest Bank?

PacWest is the first of many small regional banks that will go under this year. Most will get bought by the big four in gov orchestrated sales. This has been the playbook since 2008. Follow the incentives. Massive consolidation across the banking industry. PacWest gonna be a drop in the bucket compared to what comes next.

First, a hastened government led bank consolidation, then a public/private partnership with the remaining large banks to launch a surveilled and controlled digital currency network. We will be told it is more convenient. We will be told it is safer. We will be told it will prevent future bank runs. All of that is marketing bullshit. The goal is greater control of money. The ability to choose how we spend it and how we save it. If you control the money - you control the people that use it.

The House of Representatives will now decide whether to adopt its own proposal or the Senate’s version for the new stablecoin regulations.

The United States Senate has officially passed the GENIUS Act, marking another step toward establishing a federal regulatory framework for stablecoins. The final vote concluded with 68 in favor and 30 against, sending the bill to the House of Representatives for final approval in the coming weeks.

Republican Senator Bill Hagerty, sponsor of the bill, stated:

“The GENIUS Act establishes a pro-growth regulatory framework for payment stablecoins. This legislation will cement U.S. dollar dominance, protect consumers, and drive demand for U.S. Treasurys.”

New standards for stablecoins in the U.S.

The legislative proposal, officially titled the Guiding and Establishing National Innovation for US Stablecoins Act, sets strict legal requirements for stablecoin issuers. The bill mandates that every token must be fully backed by U.S. dollars or equally liquid assets (such as U.S. Treasurys), ensuring market stability and transparency.

Stablecoin issuers with a market capitalization exceeding $50 billion will be subject to mandatory annual audits, while foreign entities like Tether will be required to meet specific compliance rules to operate in the U.S. market.

Restrictions for Big Tech

One of the provisions of the GENIUS Act bans non-financial public companies — including giants like Meta and Amazon — from issuing stablecoins unless they meet stringent risk management and privacy standards. This measure aims to prevent potential conflicts of interest and concentrations of power in the digital currency sector.

In the event of an issuer’s insolvency, the bill grants stablecoin holders a “super-priority” status in bankruptcy proceedings, placing them ahead of other creditors in the repayment hierarchy.

Despite Senate approval, the GENIUS Act now faces a competing proposal in the House — the STABLE Act — which was advanced in committee last May. The two bills differ on key issues such as state versus federal oversight and the treatment of foreign stablecoin issuers. Reconciling these versions will be crucial before any legislation reaches President Trump’s desk for final signature.

Today, DDC Enterprise Limited (NYSE: DDC) announced it has raised three securities purchase agreements for a total of up to $528 million to expand its Bitcoin holdings. According to the press release, this is one of the largest single-purpose Bitcoin raises by any NYSE-listed company.

JUST IN: DDC Enterprise to raise up to $528 million to buy more #Bitcoin pic.twitter.com/CPxPlsjvwq

— Bitcoin Magazine (@BitcoinMagazine) June 17, 2025

“Today is a defining moment for DDC Enterprise and our shareholders,” said the Founder and CEO of DDC Enterprise Norma Chu. “This capital commitment of up to $528 million, backed by respected institutions from both traditional finance and the digital asset frontier, represents a strong mandate to execute an ambitious corporate Bitcoin accumulation strategy globally. Our vision is unequivocal: we are building the world’s most valuable Bitcoin treasury.”

The funding, backed by investors including Anson Funds, Animoca Brands, Kenetic Capital, and QCP Capital, will be primarily allocated toward significantly increasing the company’s Bitcoin holdings.

“This funding is expected to propel DDC into one of the top global corporate Bitcoin holders,” stated Chu. “This investment by Anson Funds and the group of PIPE investors is a resounding validation of Bitcoin’s important role in future corporate balance sheets.”

Components of the capital raise include:

• $26 Million Equity PIPE Investment:
  The company will issue up to 2.4 million Class A ordinary shares at an average price of $10.30 to investors including Animoca Brands, Kenetic Capital, and QCP Capital. The shares will be restricted for 180 days.

Thailand Approves Five Year Bitcoin And Crypto Tax Break 

Thailand has approved a five year tax exemption on capital gains from cryptocurrency trading made through licensed digital asset platforms. The exemption will be in effect from January 1, 2025, through December 31, 2029.

JUST IN: Thailand’s cabinet approved personal tax waiver on profits from the #Bitcoin and crypto sale over five years. pic.twitter.com/4gWc1gn84j

— Bitcoin Magazine (@BitcoinMagazine) June 17, 2025

Deputy Finance Minister Julapun Amornvivat announced the measure, calling it a move to increase investment, stimulate economic activity, and drive long term growth.

Amornvivat stated, “The Cabinet approved a five-year crypto tax exemption to promote Thailand as a global digital asset hub.” 

According to the Ministry of Finance, the policy is designed to strengthen Thailand’s competitiveness in the global digital economy. It targets transparent growth, and aims to increase capital inflow into the Thai market. Officials expect over 1 billion baht in indirect tax revenue to result from the increased economic activity during the exemption period.

Amornvivat went on to say, “The capital gain tax exemption will be for the sale of digital assets made through operators regulated by the Securities and Exchange Commission.”

The tax break applies only to platforms licensed by the Thai SEC. This includes exchanges that meet strict regulatory standards under the government’s digital finance framework. Exchanges without Thai licenses will not benefit from the exemption and continue to face restrictions.

Officials say the new exemption aligns with international standards from the OECD and FATF. The government is also exploring a possible value-added tax (VAT) on digital assets to support fiscal stability. 

Furthermore, this isn’t Thailand’s first step toward embracing Bitcoin or crypto.

Thailand approved its first spot Bitcoin ETF in 2024, allowing asset manager ONEAM to launch a fund for institutional investors. The ETF offers regulated exposure to Bitcoin through global funds and reflects growing demand for institutional access to the asset.

Thailand is taking a two sided approach. They support innovation through licensed platforms, while cracking down on unregulated players. With clearer rules and tax breaks, the country is positioning itself as a leader for Bitcoin and crypto growth in Southeast Asia.

BBVA Tells Wealthy Clients to Invest Up to 7% in Bitcoin 

Spanish bank BBVA is now advising its wealthy clients to invest up to 7% of their portfolios in crypto and Bitcoin, showing how traditional banks are starting to see the potential of Bitcoin. 

JUST IN: Spain's second largest bank BBVA is telling wealthy clients to invest in Bitcoin — Reuters pic.twitter.com/i2Pqg85uSk

— Bitcoin Magazine (@BitcoinMagazine) June 17, 2025

“With private customers, since September last year, we started advising on Bitcoin,” said Philippe Meyer, head of digital & blockchain solutions at BBVA Switzerland, during the DigiAssets conference in London. “The riskier profile, we allow up to 7% of portfolios in crypto.”

The bank’s private wealth division is currently recommending clients allocate 3% to 7% of their portfolio to Bitcoin and crypto, depending on their individual appetite. While many private banks have offered to execute Bitcoin or crypto trades upon request, it remains rare for a global financial institution to formally advise clients to buy. BBVA is currently recommending allocations specifically in Bitcoin. 

Meyer emphasized that even a modest allocation to Bitcoin can have a meaningful impact on portfolio returns, “If you look at a balanced portfolio, if you introduce 3%, you already boost the performance,” he said. “At 3%, you are not taking a huge risk.” 

BBVA began executing Bitcoin purchases for its clients in 2021, but Meyer said this is the first time it is formally advising allocations. In June 2021, the bank launched Bitcoin trading and custody services through its Swiss subsidiary for private clients. “With this innovative offer, BBVA positions itself as a benchmark institution in the adoption of blockchain technology,” said BBVA Switzerland CEO Alfonso Gómez at the time. 

BREAKING: Spain's BBVA is opening #Bitcoin trading and custody to all private banking clients in Switzerland. pic.twitter.com/2ppfs34g6F

— Bitcoin Magazine (@BitcoinMagazine) June 18, 2021

BBVA’s interest in digital currency goes back even further. As early as 2015, the bank made it clear that it viewed Bitcoin and blockchain technology as more than just a passing trend. In a statement that now seems increasingly prescient, BBVA said “institutions that understand Bitcoin and digital currencies will lead the new monetary system,” highlighting its belief that early adopters would gain a strategic advantage. 

This early support set BBVA apart from many of its peers, as few major banks were willing to publicly engage with Bitcoin at the time. 

What began as interest in blockchain technology has turned into direct investment guidance, now culminating in BBVA formally advising wealthy clients to allocate up to 7% of their portfolios into Bitcoin, a clear sign the bank sees it as a long term part of its future.

U.S. Senate Passes Stablecoin Bill The GENIUS Act

The U.S. Senate has passed the Guiding and Establishing National Innovation for U.S. Stablecoins (GENIUS) Act (S. 394) by a vote of 68-30, establishing the first comprehensive federal framework for fiat-backed stablecoins.

The bipartisan legislation was introduced by Senator Bill Hagerty and co-sponsored by Senators Tim Scott, Kirsten Gillibrand, and Cynthia Lummis. It passed under the official title “Guiding and Establishing National Innovation for U.S. Stablecoins of 2025.” 

The United States Senate has passed the GENIUS Act

— Bo Hines (@BoHines) June 17, 2025

“Today, on a bipartisan basis, the Senate passed its first piece of major legislation this Congress with my bill—the GENIUS Act,” said Senator Hagerty. “With GENIUS, the United States is one step closer to becoming the crypto capital of the world.” 

The GENIUS Act tightly regulates payment stablecoins, requiring 1:1 dollar-backed reserves, monthly disclosures, audits, and clear federal or state licensing. It prohibits algorithmic coins and places strict limitations on rehypothecation and commingling of reserves. Importantly, the bill also amends existing securities laws to explicitly state that compliant stablecoins are not securities—freeing them from SEC jurisdiction.  

While the bill is aimed at stablecoins, many Bitcoin proponents see it as a win since stablecoins can act as a bridge into Bitcoin, enabling on-ramps, easier settlements, and institutional access. 

And as the financial system modernizes, trusted access points like dollar-backed tokens could play a role in onboarding new Bitcoin users—especially in international markets and corporate treasuries. 

“The U.S. Senate has passed the GENIUS Act — landmark stablecoin legislation that provides regulatory clarity, enhances consumer protection, and extends U.S. dollar dominance online,” said President Donald Trump’s AI & Crypto Czar David Sacks. “Thanks to President Trump for his leadership on crypto & Senator Hagerty for authoring the bill.”

The passage of the GENIUS Act may be the clearest signal yet that the U.S. is preparing for a stablecoin and Bitcoin-powered future.

Swiss Bitcoin Platform Relai & Casa Partner to Offer Multisig Bitcoin Security

Today, Relai, a Swiss Bitcoin platform, announced it has partnered with Casa to introduce a new Bitcoin saving and security solution, according to a press release sent to Bitcoin Magazine.

“Self-custody is at the heart of Bitcoin’s promise,” said the Co-Founder and CTO of Relai Adem Bilican. “As our users continue to accumulate and grow their holdings over time, we recognize the need for long-term solutions designed for serious Bitcoin enthusiasts. Casa is the ideal partner – a sovereignty-focused and user-friendly solution. Together, we’re helping users secure not just their savings, but their legacy.” 

According to the press release, the app has over 500,000 downloads, more than 85,000 active users, and a total user investment exceeding $1 billion. These figures reflect growing user engagement with self-custody Bitcoin solutions intended for long-term use.

Self-custody is a fundamental aspect of Bitcoin ownership, but it also comes with certain risks, particularly around long-term security. The partnership introduces a multisignature (multisig) custody option, which requires multiple keys to access funds. This setup can help mitigate the vulnerabilities of single-key storage.

Through the integration, users who purchase Bitcoin via Relai will have the option to store their assets using Casa’s multisig system. The offering also includes an inheritance feature that allows users to designate a beneficiary, adding a layer of planning for asset transfer across generations.

“Casa’s mission is to maximize sovereignty and security in the world,” stated the CEO of Casa Nick Neuman. “The best way we can do that today is by making sovereign bitcoin custody as safe and simple as possible. Our partnership with Relai will help people stack bitcoin and store it securely, for themselves and their families.”

According to both companies, the integration represents a first-of-its-kind model that combines Bitcoin accumulation with long-term custody and inheritance planning for everyday users.

A new study by Kraken reveals how cryptocurrency investors perceive security as the main challenge in self-managing their digital assets.

According to The Block, a recent survey conducted by crypto exchange Kraken found that nearly half of respondents consider themselves the primary risk factor for their own crypto security. The research, which surveyed 789 participants, highlights that 48% of users see their own actions as the greatest threat to their investments in digital assets, surpassing concerns about external theft or fraud.

Kraken’s report underlines how personal responsibility in security management forces users to take full control of their digital funds. However, the study suggests that this autonomy can also become a source of anxiety for many investors.

Nick Percoco, Chief Security Officer at Kraken, commented on the findings, noting that “a lack of confidence in personal crypto security is capping the growth of the industry.” According to Percoco, unlocking the full potential of cryptocurrencies will require users to embrace self-custody and consistently invest in strong security habits.

Technologies to strengthen security

Despite the concerns highlighted in the study, 31% of participants expressed optimism about future technologies that could improve crypto security. Among the most promising solutions identified:

• advanced biometric systems for user authentication;
• multi-factor authentication to secure wallet access;
• AI-based fraud detection systems to prevent attacks.

Data and case studies

Kraken’s research emerges in a context where security threats remain a pressing reality. FBI data shows that in 2024, nearly 150,000 reports of crypto-related internet fraud resulted in $9.3 billion in losses. Older users, particularly those over 60, proved especially vulnerable, accounting for $3 billion in crypto-related financial fraud losses on their own.

Prenetics Becomes First Healthcare Firm to Launch Bitcoin Treasury Strategy With $20M BTC Purchase

Prenetics Global Limited, a health sciences company, announced today that it has purchased $20 million worth of Bitcoin as part of a newly approved corporate treasury strategy. The company acquired 187.42 BTC at an average price of $106,712 and stated that its board has approved allocating the majority of its $117 million balance sheet to Bitcoin. 

This follows the company’s strategic transfer of ownership of ACT Genomics, which increased its pro-forma cash to approximately $66 million and total liquid assets, including BTC and short-term holdings, to around $117 million. 

According to a press release sent to Bitcoin Magazine, Danny Yeung, CEO of Prenetics stated, “With our strengthened balance sheet of $117 million in cash, BTC and short-term assets, we now have the financial foundation to pioneer innovative treasury management approaches, including our historic Bitcoin treasury strategy.” 

Prenetics also announced the appointment of Andy Cheung, former COO of cryptocurrency exchange OKEx, to its Board of Directors. Cheung noted that the company’s Bitcoin strategy will include active treasury management, using tools such as derivatives and structured products. 

“This isn’t about passive Bitcoin storage,” said Cheung. “We’re talking about dynamic treasury management using derivatives, yield strategies, and institutional-grade trading techniques.”

Prenetics plans to expand its Bitcoin holdings through institutional capital partnerships and to implement advanced return strategies. It also plans to accept Bitcoin payments across its direct to consumer platforms, including IM8 Health and CircleDNA.

In addition to Cheung, the company is working with two industry advisors, Tracy Hoyos Lopez, Chief of Staff at Kraken and a board member at the Bitcoin Advocacy Project, and Raphael Strauch, founder of crypto conference TOKEN2049. 

“This is not a short-term play or market timing decision,” said Yeung. “We are implementing a comprehensive, long-term Bitcoin strategy that we believe will fundamentally transform our company’s value proposition.”

Prenetics reported strong recent growth, including a 336.5% year over year revenue increase in Q1 2025. It now operates three consumer health brands and maintains a deb free balance sheet. 

Prenetics’ strategy shows Bitcoin’s tremendous growth and potential. But this time, from within the healthcare sector.

K33 Announces Plans To Purchase Up To 1,000 Bitcoin

K33 AB, a leading digital asset brokerage and research firm, announced today the launch of a SEK 85 million direct share issue to fund the purchase of Bitcoin. The company aims to build Bitcoin as a core asset on its balance sheet, targeting the accumulation of up to 1,000 BTC as a strategic reserve.

PRESS RELEASE: K33 launches a share issue to finance the purchase of up to 1000 Bitcoin, with a minimum of SEK 85 million secured through pre-commitments pic.twitter.com/sG1LZjR6EI

— K33 (@K33HQ) June 18, 2025

The share issue, priced at SEK 0.1036 per share, is fully backed by existing shareholders and new investors. Proceeds from the raise will be used exclusively to acquire BTC, supporting K33’s accumulation strategy revealed in May. By acquiring BTC, the company aims to strengthen its balance sheet, boost brokerage margins, launch new products, and attract more investors.

“This raise marks a major milestone towards our initial goal of acquiring 1000 BTC before scaling further,” commented the CEO of the Company Torbjørn Bull Jenssen. “We strongly believe that Bitcoin represents the future of global finance and are positioning K33 to benefit maximally from this. A strong balance sheet built on Bitcoin enables us to significantly improve our brokerage operation while maintaining full exposure to Bitcoin’s upside potential.”

As part of the strategy, K33 recently completed its first Bitcoin acquisition, purchasing 10 BTC for approximately SEK 10 million on June 3. This transaction is the initial deployment of capital from the SEK 60 million investment commitment announced earlier this year to support the company’s BTC treasury.

“We expect Bitcoin to be the best-performing asset in the coming years and will build our balance sheet in Bitcoin moving forward,” stated Jenssen. “This will give K33 direct exposure to the Bitcoin price and help unlock powerful synergies with our brokerage operation. Our ambition is to build a balance of at least 1000 BTC over time and then scale from there.”

During its Q1 2025 Report and Strategic Outlook presentation, K33 underscored the accelerating institutional adoption of Bitcoin, referencing the rapid growth of the US Bitcoin ETFs, which attracted more capital in its first year than gold ETFs had in the past two decades.

“For K33, Bitcoin is not only a high-conviction asset — it’s also a strategic enabler,” Jenssen said. “With a sizable BTC reserve, we will be able to strengthen our financial position while unlocking new revenue streams, product capabilities, and partnerships.”

As I read the news over the past week, we’ve heard of Ukrainian drone attacks on Russia’s nuclear attack planes and Russia’s threats of retaliation. We’ve heard of Israel attacking Iran’s nuclear facilities and Iran returning attacks on Israel’s major cities. I’ve read of AI taking jobs, threatening someone trying to turn it off, and refusing to turn off. There are threats of inflation, market crashes, housing crashes, and monetary crashes. There are riots across the US. There are warnings of potential new pandemics or of calls for terrorist cells to awaken and attack. It is easy to get overwhelmed by everything happening in the world. It is easy to become fearful of everything, but God does not call us to be afraid. He repeatedly tells us to “trust him” and to “fear not.”

Do not fear, for I am with you;\ Do not anxiously look about you, for I am your God.\ I will strengthen you, surely I will help you,\ Surely I will uphold you with My righteous right hand.’ (Isaiah 41:10)

With all of the crazy going on in the world, it is easy to worry about our jobs, our families, our country, and even our lives, but God does not want us to worry. He wants us to trust in Him in all things.

And He said to His disciples, “For this reason I say to you, do not worry about your life, as to what you will eat; nor for your body, as to what you will put on. For life is more than food, and the body more than clothing. Consider the ravens, for they neither sow nor reap; they have no storeroom nor barn, and yet God feeds them; how much more valuable you are than the birds! And which of you by worrying can add a single hour to his life’s span? If then you cannot do even a very little thing, why do you worry about other matters? Consider the lilies, how they grow: they neither toil nor spin; but I tell you, not even Solomon in all his glory clothed himself like one of these. But if God so clothes the grass in the field, which is alive today and tomorrow is thrown into the furnace, how much more will He clothe you? You men of little faith! And do not seek what you will eat and what you will drink, and do not keep worrying. For all these things the nations of the world eagerly seek; but your Father knows that you need these things. But seek His kingdom, and these things will be added to you. Do not be afraid, little flock, for your Father has chosen gladly to give you the kingdom. (Luke 12:22-32) {emphasis mine}

God provides for His own. He doesn’t always provide in the way we wish, but He does provide when we trust in Him. Even when believers die, He provides them a place in heaven.

When we look at the world around us, where everything seems like it is falling apart and/or turning to evil, we need to keep our eyes on Jesus and on eternity.

Therefore we do not lose heart, but though our outer man is decaying, yet our inner man is being renewed day by day. For momentary, light affliction is producing for us an eternal weight of glory far beyond all comparison, while we look not at the things which are seen, but at the things which are not seen; for the things which are seen are temporal, but the things which are not seen are eternal. (2 Corinthians 4:16-18) {emphasis mine}

What we experience here on earth may sometimes be unpleasant, but it is a “momentary, light affliction” compared to the glory of heaven. Just as labor and delivery of a child is hard and unpleasant, but is worth every effort and pain when you hold your child, in the same way our suffering on earth will seem like nothing compared to the joy of being in the presence of our Creator God and Savior.

My Experiences

I used to try to prepare for everything. When I was young, I would say, “a good Girl Scout is always prepared.” When I got married and had kids, I started trying to prepare for anything that might possibly go wrong. I had extra food, water, and medical supplies. I started a garden. I got chickens. I got rid of chickens when I developed a lung allergy and couldn’t breathe.

None of that was wrong in itself. I’d even argue it could be wise actions, but I was relying on myself and stuff to face the troubles of this world instead of relying on God. That was definitely not good and was not the way to peace.

We also got involved in politics. My husband was in the state legislature. I was a precinct person and involved in precinct, county, state, and national meetings. I helped set the platform for our state political party in two elections and helped set the resolutions in another.

None of that was wrong in itself. I’d even argue that Christians are called to be a blessing to our earthly nations, but it wasn’t the way to peace, nor was it putting my time in effort into the most important things.

I’ve been reading my Bible daily for 40+ years and reading the Bible in a year for 20+ years. For more than a decade I intensely studied the beginnings, Genesis and how science and archaeology support every fact in Genesis. That study really taught me the power of God and how He always keeps His promises.

For the past several years, I’ve switched to spending most of my intense study on end times prophecy. Despite the fact that the end times prophecies predict a time of unimaginable hardship, the promises of the rapture, the millennial kingdom, and eternity with Jesus in heaven brings great peace. The crazy, evil, and agony in the world is not the world falling apart, but God’s controlled, merciful judgment on the world. I can see the light at the end of the tunnel. I don’t just see everything that can possibly go wrong. I trust God with my life and that of my family.

I still have extra food, water, and medical supplies on hand, but I don’t obsess about it, nor do I put all my trust in my preparations. I still vote, but I have pulled back from political life. I have learned to trust Jesus in these difficult times. I try to be wise, but not worry about every thing that could possibly go wrong. I have gained peace.

But the Helper, the Holy Spirit, whom the Father will send in My name, He will teach you all things, and bring to your remembrance all that I said to you. Peace I leave with you; My peace I give to you; not as the world gives do I give to you. Do not let your heart be troubled, nor let it be fearful. You heard that I said to you, ‘I go away, and I will come to you.’ If you loved Me, you would have rejoiced because I go to the Father, for the Father is greater than I. Now I have told you before it happens, so that when it happens, you may believe. (John 14:26-29) {emphasis mine}

Studying God’s word enables me to know God’s power, trust His promises, and know His predictions. I don’t need to worry because God is in control of everything that happens in the world.

Let your gentle spirit be known to all men. The Lord is near. Be anxious for nothing, but in everything by prayer and supplication with thanksgiving let your requests be made known to God. And the peace of God, which surpasses all comprehension, will guard your hearts and your minds in Christ Jesus. (Philippians 4:5-7) {emphasis mine}

I really can know the “peace of God, which surpasses all comprehension.”

What We Need for Peace

Knowing God’s word can give us peace. We can bring Bible verses to mind as reminders of His promises given and His promises fulfilled. I am going to go through a bunch of verses that we can bring to mind when we are feeling worried and fearful. I’ll probably make a few comments, but I want God’s word to speak to you.

When I am afraid,\ I will put my trust in You.\ In God, whose word I praise,\ In God I have put my trust;\ I shall not be afraid.\ What can mere man do to me? (Psalm 56:3-4)

It is hard to be afraid when you are praising God.

While He was still speaking, they came from the house of the synagogue official, saying, “Your daughter has died; why trouble the Teacher anymore?” But Jesus, overhearing what was being spoken, said to the synagogue official, “Do not be afraid any longer, only believe.” (Mark 5:35-36)

Once trusting Jesus as Savior, we don’t need to be afraid of anything, just believe.

The Lord also will be a stronghold for the oppressed,\ A stronghold in times of trouble;\ And those who know Your name will put their trust in You,\ For You, O Lord, have not forsaken those who seek You. (Psalm 9:9-10)

No matter what we are going through, God is with us and working through us for good. We are never left alone.

And we know that God causes all things to work together for good to those who love God, to those who are called according to His purpose. (Romans 8:28)

God may allow hard times to come, but it is always for good. There is no pointless pain.

Be strong and courageous, do not be afraid or tremble at them, for the Lord your God is the one who goes with you. He will not fail you or forsake you. (Deuteronomy 31:6)

It is amazing how we can deal with hardships when we rely on God and not our own power.

For the eyes of the Lord are toward the righteous,\ And His ears attend to their prayer,\ But the face of the Lord is against those who do evil.

Who is there to harm you if you prove zealous for what is good? But even if you should suffer for the sake of righteousness, you are blessed. And do not fear their intimidation, and do not be troubled, 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; and keep a good conscience so that in the thing in which you are slandered, those who revile your good behavior in Christ will be put to shame. (1 Peter 3:12-16) {emphasis mine}

How amazing is it that suffering can actually be a blessing. There is no witness stronger than the person who keeps the faith and has joy and hope in suffering.

Do not fret because of evildoers,\ Be not envious toward wrongdoers.\ For they will wither quickly like the grass\ And fade like the green herb.\ *Trust in the Lord and do good*;\ Dwell in the land and cultivate faithfulness.\ Delight yourself in the Lord;\ And He will give you the desires of your heart.\ *Commit your way to the Lord*,\ Trust also in Him, and He will do it. (Psalm 37:1-5) {emphasis mine}

When we trust in God, commit our way to Him, and delight in Him, we can have joy in any situation.

Open the gates, that the righteous nation may enter,\ The one that remains faithful.\ **The steadfast of mind You will keep in perfect peace,\ Because he trusts in You.\ Trust in the Lord forever,\ For in God the Lord, we have an everlasting Rock. (Isaiah 26:2-4) {emphasis mine}

What a promise! “The steadfast of mind You will keep in perfect peace, because he trusts in You.”

I know your tribulation and your poverty (but you are rich), and the blasphemy by those who say they are Jews and are not, but are a synagogue of Satan. Do not fear what you are about to suffer. Behold, the devil is about to cast some of you into prison, so that you will be tested, and you will have tribulation for ten days. Be faithful until death, and I will give you the crown of life. (Revelation 2:9-10) {emphasis mine}

Do you think of tribulation and poverty as riches? If you trust Jesus, then you are rich in blessings when you experience tribulation and poverty. God does not promise His people ease in this life, but He does promise to use every pain and hardship for good — for our good, the good of others, and His glory. We need to trust Jesus and not fear.

Trust in the Lord with all your heart\ And do not lean on your own understanding.\ In all your ways acknowledge Him,\ And He will make your paths straight.\ *Do not be wise in your own eyes;\ Fear the Lord* and turn away from evil.\ It will be healing to your body\ And refreshment to your bones.** (Proverbs 3:5-8) {emphasis mine}

I need this verse: “Trust in the Lord with all your heart, and do not lean on your own understanding.” I definitely want to lean on my own power and understanding and have to remind myself of God’s power, wisdom, and goodness continually so I lean on Him. You have to love what God promises when we trust in Him alone: “healing to your body and refreshment to your bones.” Doesn’t that sound wonderful?

For this reason I remind you to kindle afresh the gift of God which is in you through the laying on of my hands. For God has not given us a spirit of timidity, but of power and love and discipline.

Therefore do not be ashamed of the testimony of our Lord or of me His prisoner, but join with me in suffering for the gospel according to the power of God, who has saved us and called us with a holy calling, not according to our works, but according to His own purpose and grace which was granted us in Christ Jesus from all eternity, (2 Timothy 1:6-9) {emphasis mine}

If you haven’t relied on God for everything for a long time, a call to “join with me in suffering for the gospel” probably sounds crazy, but when we live a life “not according to our works, but according to His own purpose and grace” we quickly learn how everything in life brings more peace and joy. It doesn’t make it easier or nicer necessarily, but it does bring peace and joy like you can’t imagine.

Whoever confesses that Jesus is the Son of God, God abides in him, and he in God. We have come to know and have believed the love which God has for us. God is love, and the one who abides in love abides in God, and God abides in him. By this, love is perfected with us, so that we may have confidence in the day of judgment; because as He is, so also are we in this world. There is no fear in love; but perfect love casts out fear, because fear involves punishment, and the one who fears is not perfected in love. (1 John 4:15-18) {emphasis mine}

If we repent of our sins and confess Jesus as Lord, the God and Creator of the universe lives in us. Is there anything more magnificent? When we trust in Jesus, “we may have confidence in the day of judgment.” When we love God, He loves us and “perfect love casts out fear.”

What Would I Do?

My son with Down Syndrome loves watching this show called “Mayday, Air Disaster.” It goes through different, real plane crashes and reviews how they figured out why the plane crashed. Sometimes everyone dies. Sometimes everyone lives. Sometimes some live and some die.

Watching this show and seeing the people (in reenactments) screaming in terror as the plane plummets to the ground makes me wonder how I would react in a similar circumstance. If I wasn’t a Christian, I’d probably never set foot on a plane again after watching the show. I’d like to think I would be like Jesus calmly praying “into thy hands I commit my spirit,” but I might be frantically gripping the armrests and screaming like the rest. I don’t guess anyone truly knows until they experience something like that.

Whatever the case, whether we act in perfect faith or whether we have a moment of weakness in fear of danger, pain, and the unknown, Jesus will be there with us, if we have trusted in Jesus as Savior. Everything is better with Jesus.

May our Lord, Creator, and Savior keep us in total faith, love, peace, and joy in Him so that we do not fear, no matter what trials we face. May He help us to lean on Him and not try to do everything ourselves or rely on stuff. May our faithful service and hope during trial glorify Him and draw many to Him.

O protocolo Matrix é um sistema de comunicação descentralizado de código aberto que fornece uma plataforma para mensageiros descentralizados. O Element foi lançado em 2014 como uma implementação do protocolo Matrix, originalmente conhecido como Riot.im , A ideia do Element nasceu quando Matthew Hodgson e Amandine Le Pape, dois desenvolvedores de software, decidiram criar uma plataforma de comunicação aberta e segura, que permitisse aos usuários terem total controle sobre suas informações. Eles acreditavam que a internet deveria ser um lugar onde as pessoas pudessem se comunicar livremente, sem se preocupar com a privacidade de suas informações.

O Element é um aplicativo de chat gratuito e de código aberto disponível em várias plataformas, incluindo desktop, web e aplicativos móveis. Ele oferece criptografia de ponta a ponta, o que significa que as mensagens são protegidas e só podem ser lidas pelo remetente e pelo destinatário. Além disso, o Element é descentralizado, o que significa que ele não é controlado por uma única entidade, mas sim por uma rede global de servidores.

O Element é amplamente utilizado por indivíduos e empresas que desejam ter uma comunicação segura e privada. É frequentemente usado por equipes de projetos, organizações sem fins lucrativos e grupos ativistas que precisam compartilhar informações confidenciais e se comunicar de forma segura. O Element também é conhecido por seu recurso de salas públicas, que permite que os usuários se juntem a grupos de discussão sobre vários tópicos de interesse.

Uma das principais vantagens do Element é sua arquitetura descentralizada. Ao contrário das plataformas de mensagens convencionais que centralizam os dados em seus próprios servidores, o Element utiliza uma rede descentralizada, distribuindo as informações em diversos servidores espalhados pelo mundo. Isso significa que os dados dos usuários são menos suscetíveis a ataques cibernéticos e invasões, já que não são centralizados em um único ponto vulnerável.

Para usar o Element, normalmente os usuários precisam se registrar em um servidor Matrix. Existem várias opções disponíveis, incluindo servidores públicos e privados. No entanto, outra opção é criar um servidor próprio para usar o Element.

O Element também utiliza criptografia de ponta a ponta para proteger as mensagens e arquivos trocados entre os usuários. Isso significa que apenas o remetente e o destinatário das mensagens podem ler o conteúdo, garantindo que as informações permaneçam seguras e privadas.

Outra vantagem do Element é sua ampla variedade de recursos, incluindo videochamadas criptografadas, compartilhamento de tela e integração com outros serviços, como calendários e aplicativos de produtividade. Isso torna o Element uma plataforma completa de comunicação e colaboração, adequada para uso pessoal e empresarial.

O Element também é fácil de usar e possui uma interface intuitiva e personalizável. Os usuários podem personalizar a aparência do aplicativo e acessar diferentes configurações e recursos com apenas alguns cliques.

Carl Rickertsen completely exits his position in Strategy as insiders sell $864 million worth of stock.

As reported by Protos, Carl Rickertsen, a member of Strategy’s board of directors, has fully liquidated his entire shareholding for over $10 million.

Rickertsen’s decision to completely exit his Strategy position marks a sharp shift from his previous investment stance. In 2022, the executive had shown confidence in the company by investing $700,000 in MSTR shares.

On June 13, 2022, Rickertsen purchased $608,000 worth of MSTR stock at $152 per share. Since then, the stock has rallied 152%. However, by 2023, the director had already sold half of his 4,000-share position.

Rickertsen’s approach to managing his holdings has become increasingly aggressive in recent years. Since joining the board in 2019, he has adopted a strategy of immediately liquidating any stock options received.

One example of this tactic occurred on June 2, when he acquired and sold 26,390 MSTR shares on the same day.

As of June 5 this year, Rickertsen reported zero vested Strategy shares, marking the end of his equity involvement with the company.

Rickertsen’s situation is not an isolated case within Strategy. Data from the Securities and Exchange Commission (SEC) reveals a controversial picture. According to information gathered by secform4.com, over the past five years, total insider sales have exceeded purchases by $864 million. This imbalance in insider transactions could raise questions about executives’ confidence in the company’s future.

The banking giant is exploring an expansion of its blockchain services, focusing on digital payments and currencies.

JPMorgan Chase has filed a new trademark application for the name “JPMD.” The filing was submitted on June 15 to the United States Patent and Trademark Office (USPTO).

The application, filed by JPMorgan Chase Bank, N.A., covers a broad range of services related to digital assets and blockchain technology. These include the issuance of digital currencies, electronic payment processing, and financial custody services — all of which suggest a possible new stablecoin initiative for JPMorgan.

Experience with JPM Coin

This move wouldn’t be JPMorgan’s first foray into blockchain-based finance. The bank already operates JPM Coin, a dollar-pegged stablecoin used to enable instant transactions between institutional clients. The token runs on Quorum, a private blockchain network developed in-house by JPMorgan and based on Ethereum’s technology.

The registration of the JPMD trademark comes as JPMorgan and other major U.S. banks are considering a collaborative stablecoin project through their jointly owned entities: Early Warning Services and The Clearing House.

Similarly, corporations like Walmart and Amazon are mulling the creation of their own stablecoins.

The internet has no instruction manual. Anyone can post freely, which means unwanted spam can flood your replies, feed, and notifications. New domains call for new practice, and joining a paid relay is one way you can protect yourself against nostr spam. As a relay is also community focused, it aims to be a way for those new to nostr to find fitra and ummah in cyber-space, thereby building and joining patterns of higher-purpose.

NoorNode is a nostr relay dedicated for muslims on nostr. It is maintained and moderated by the Pnostr:npub1vmgf2pzv8k3fsch2hvc5uqnp9kvrxwrfgucek95528zax3syfwtqhykxpn team, which is a podcast incubator project for the creation of Islamic media on nostr.

The Noor Node relay is free to read. All content posted to the relay is public. However, one must pay to join the relay in order to post content to it. This payment feature is small but necessary proof-of-work barrier to keep bots and spam out.

---

How To Join:

If you simply want to read notes on NoorNode, just add wss://noornode.nostr1.com to your read/inbox relays in your client settings.

To join NoorNode and post notes to the relay, visit the RelayTool explorer page at https://noornode.nostr1.com

Click on the gear button to show options and it will reveal a side pannel where you can submit your payment.

Enter your nostr public address (npub) into the text box and select the Lightning Pay ✅ ⚡ button for it to generate an invoice QR code.

Once payment has been received a lightning bolt will animate across the screen and you will be able to post to the NoorNode relay.

---

Client Relay Cofigurations:

The RelayTool explorer is a very basic client which can be used to post to NoorNode, but for best user experience other clients will be preferable. So long as NoorNode set as a write/outbox relay in a client's settings, any client should work. That said, clients where you can customize the relay feeds are preferable. Of these, Yakihonne is the one we recommend due to it's support for both mobile (Andriod & iOS) and desktop.

To create a custom feed for NoorNode in Yakihonne from the desktop home page, select the gear button in the Note feed dropdown menu.

A widget will then pop up where NoorNode can be added as a custom relay feed. Enter wss://noornode.nostr1.com and hit the + button and then select the Update bottom to save the custom feed.

The NoorNode relay can then be viewed as a seperate feed from Yakihonne's home page by selecting it from the note feed dropdown menu (scroll to the bottom to find it).

Other clients, like Jumble, can also funtion as great ways to test out customized relay feeds. As nostr continues to grow, it is expected that more clients will include this feature.

To learn more about relays and how they work on nostr, check out this guide from the developer of Amethyst

Relay Setup by Vitor Pamplona

The intention behind NoorNode is for muslims on nostr to have a safe place to build community while not having to worry about issues like spam or religious intolerance. The payment to post is designed to enough to keep most bots out while also not being a significant barrier for anyone who want to enage. The mission of nostr:npub1vmgf2pzv8k3fsch2hvc5uqnp9kvrxwrfgucek95528zax3syfwtqhykxpn is to create new Islamicate mythos. We hope that the community that grows around NoorNode will embody that same goal and that the Noor of Islam will be able to radiate, even from nostr.

Please keep in mind that NoorNode is a public relay and notes posted can be picked up by others relays. If any content found on the relay does not seem appropriate or if any issues occure that cause concern, please reach out to the PodSystems team for support.

May the peace and blessings of the most merciful God be with you and light your way on nostr.

Desde a sua criação em 2008, Bitcoin tem sido visto como um desafio direto ao sistema bancário tradicional. Desenvolvido como uma alternativa descentralizada ao dinheiro fiduciário, Bitcoin oferece uma forma de armazenar e transferir valor sem depender de bancos, governos ou outras instituições financeiras. Essa característica faz com que seja considerado um símbolo de resistência contra um sistema financeiro que, ao longo do tempo, tem sido marcado por crises, manipulações e restrições impostas aos cidadãos.

Crise financeira de 2008 e o nascimento de Bitcoin

Bitcoin surgiu em resposta à crise financeira de 2008, um colapso que revelou as falhas do sistema bancário global. Bancos centrais imprimiram grandes quantidades de dinheiro para resgatar instituições financeiras irresponsáveis, enquanto milhões de pessoas perderam as suas casas, poupanças e empregos. Nesse contexto, Bitcoin foi criado como um sistema financeiro alternativo, onde não existe uma entidade central com o poder de manipular a economia em benefício próprio.

No primeiro bloco da blockchain ou timechain de Bitcoin, Satoshi Nakamoto incluiu a seguinte mensagem:

"The Times 03/Jan/2009 Chancellor on brink of second bailout for banks."

Essa frase, retirada de uma manchete de jornal da época, simboliza a intenção de Bitcoin de oferecer um sistema financeiro fora do controlo dos bancos e dos governos.

Principais razões pelas quais Bitcoin resiste ao sistema bancário

Descentralização: Ao contrário do dinheiro emitido por bancos centrais, Bitcoin não pode ser criado ou controlado por nenhuma entidade específica. A rede de utilizadores valida as transações de forma transparente e independente.

Oferta limitada: Enquanto os bancos centrais podem imprimir dinheiro sem limites, causando inflação e desvalorização da moeda, Bitcoin tem uma oferta fixa de 21 milhões de unidades, tornando-o resistente à depreciação artificial.

Impossibilidade de censura: Bancos podem bloquear contas e impedir transações a qualquer momento. Com Bitcoin, qualquer pessoa pode enviar e receber fundos sem pedir permissão a terceiros.

Autocustódia: Em vez de confiar os seus fundos a um banco, os utilizadores de Bitcoin podem armazenar as suas próprias moedas, sem risco de congelamento de contas ou falências bancárias.

Conflito entre bancos e Bitcoin

Ataques mediáticos: Grandes instituições financeiras frequentemente classificam Bitcoin como arriscado, volátil ou inútil, tentando desincentivar a sua adoção.

Regulação e repressão: Alguns governos, influenciados pelo setor bancário, têm criado restrições ao uso de Bitcoin, dificultando a sua compra e venda.

Criação de alternativas centralizadas: Muitos bancos centrais estão a desenvolver moedas digitais (CBDCs) que mantêm o controlo do dinheiro digital, mas sem oferecer a liberdade e a descentralização de Bitcoin.

Resumindo, o Bitcoin não é apenas uma moeda digital, mas um movimento de resistência contra um sistema financeiro que falhou repetidamente em proteger o cidadão comum. Ao oferecer uma alternativa descentralizada, transparente e resistente à censura, Bitcoin representa a liberdade financeira e desafia o monopólio dos bancos sobre o dinheiro. Enquanto o sistema bancário tradicional continuar a impor restrições e a controlar o fluxo de capital, Bitcoin permanecerá como um símbolo de independência e soberania financeira.

Muito obrigado por teres lido o texto até aqui, espero que esteja tudo bem contigo e um abraço enorme do teu madeirense bitcoiner maximalista favorito. Viva a liberdade!

The case for a neutral, permissionless monetary protocol has never been stronger. The incumbent financial system is a permissioned wall garden that is susceptible to a tax. When you're using this system, you don't own your money. Your money doesn't really even exist. What you have is a claim to be able to ask your bank to give you your money or move it somewhere that you desire. Not only is it a permissioned wall garden, but it is an insecure permissioned wall garden that is susceptible to attacks from nefarious actors.

This was made very clear earlier today when Sepah Bank in Iran was the subject of a cyber attack that led to all of its databases being erased and their ATMs being deemed non-functional. Sepah Bank customers have been unable to withdraw cash. And many are warning Iranian citizens to withdraw as much cash as possible from any ATM outside of Sepah Bank's network that is working. Because there is a high likelihood that other banks and ATM networks will be targeted.

Bitcoin is a digital bearer instrument that you can custody yourself using either a software or hardware wallet. The network is operated by an army of geographically distributed nodes that maintain the rules and ensure that anybody trying to transact within the network is doing so within the rules that are set forth. Bitcoin is a push system, not a pull system. It is extremely hard to attack in the way that Sepah Bank was attacked earlier today.

I think it's important to note the way in which Sepah Bank was attacked and highlight that it is starkly different from the types of attacks or shortcomings from the financial system that we've seen over the years.

One of the events that caused a rush to Bitcoin over a decade ago was the banking crisis in Cyprus. We've seen hyperinflationary events in countries like Lebanon and Turkey that have rendered their currencies defunct. In the case of Lebanon, the central bank simply came out and said that people were not going to have access to their money and gave Lebanese citizens an overnight haircut on their savings. We've seen countries like India and Nigeria mess with their physical bills, forcing their citizens to exchange smaller denominations for larger denominations, causing massive disruptions in the process.

We've seen the United States government and its allies freeze the treasury assets of its enemies and they move towards a more multipolar monetary order over the last five years. We've seen the Canadian government freeze the bank accounts of protesters fighting for bodily autonomy. We've seen Operation Chokepoint 1.0 and 2.0. Here in the United States, the government directly targeted industries and businesses within those industries by either overtly preventing them from accessing bank accounts or covertly making it as hard as possible to access bank accounts.

On top of all this, obviously, we have the constant drumbeat of currency debasement across the world, even here in the United States, where the Federal Reserve and Federal Government are expanding the monetary base and going further into debt, ultimately destroying the purchasing power of the dollar at an increasing rate over time.

However, this type of cyber attack on a bank is unique, at least from what I can recall. The ability of nefarious actors to access bank databases and erase them is something new and something that should not be taken lightly. If Iranian hacking capabilities are as sufficient and capable as we are led to believe, it's not hard to imagine that we could see some retaliatory actions from the Iranian regime to counteract the attack on their banking system.

I don't want to incite alarm in any of you, but I think it is important to highlight that this new attack vector is definitely a step towards financial nihilism that could put hundreds of millions, if not billions of people in harm's way, in the sense that they could wake up one morning and be told that the bank does not have access to the records of their cuck buck IOUs. If something like this were to happen, I'm sure anyone who isn't holding Bitcoin in a wallet that they control will really wish they were. Being able to access your money is a vital part of being able to live you life. The thought of that ability being taken away because of a hacking war that breaks out is extremely unnerving.

As I said at the top of this letter, the case for a neutral, permissionless, distributed monetary system with a native currency that is finite is clearer than it ever has been, at least for me. It is imperative that you and anyone that you care about holds Bitcoin in self-custody to inoculate yourselves from these very real risks that are only going to increase from here on out.

Eliminate the trusted third party risks that exist in your life. Use Bitcoin as your money and use it correctly by holding it in self-custody.

Why 5% Interest Rates Won't Trigger The Next Market Crash

Guest Mel Mattison challenges the prevailing fear around rising interest rates, arguing that markets have developed immunity to higher yields. Unlike 2023's sharp selloff when the 10-year hit 5%, Mattison believes equities and Bitcoin can now absorb these levels because they signal stronger growth expectations ahead. He emphasizes that the pace of rate increases matters more than absolute levels, and notes that markets have had time to adjust. With oil trading at just $65 per barrel—a fraction of its inflation-adjusted 2008 peak of over $200—the deflationary pressure from cheap energy provides a crucial buffer.

> "It's not just what the rate we get to, it's how fast we get there." - Mel Mattison

Mattison's most compelling argument centers on AI-driven productivity gains enabling companies to maintain margins despite higher borrowing costs. As I've witnessed firsthand implementing AI tools at TFTC, what once required hiring multiple employees can now be handled by one person with the right automation. This productivity revolution means traditional rate sensitivity models may no longer apply.

Your mind will berate you in performance. It’s self centered thinking that ruins your performance, it isolates you. Instead of being immersed in the experience of the game, you are caught in a web of your own stinking thinking.

Only thinking of yourself and how you will perform.

How others will judge you.

In your fear of what others think, you create the reality for them to judge you. You create an opportunity for them to distrust your gifts. Your fear is small and selfish. You must let go of oneself in order to be the creative expression of art.

Expression has no individual behind it, it is a force beyond small little me. Where once you took a step now it is the step that takes you.

We haven’t forgotten how to trust ourselves. We have forgotten how to love and accept ourselves and it shows when we contract and tighten under pressure.

Pressure is a spotlight it magnifies and calls you to bring forth your greatest gist, your greatest expression. Do not let the spotlight hinder you, most people are running from the light but the light always follows you, it’s like a shadow.

Until you come to accept that you are always in the spotlight only then can you realize what you do behind the scenes is also the scene itself.

The new website is finally live! I put in a lot of hard work over the past months on it. I'm proud to say that it's out now and it looks pretty cool, at least to me!

Why rewrite it all?

The old kycnot.me site was built using Python with Flask about two years ago. Since then, I've gained a lot more experience with Golang and coding in general. Trying to update that old codebase, which had a lot of design flaws, would have been a bad idea. It would have been like building on an unstable foundation.

That's why I made the decision to rewrite the entire application. Initially, I chose to use SvelteKit with JavaScript. I did manage to create a stable site that looked similar to the new one, but it required Jav aScript to work. As I kept coding, I started feeling like I was repeating "the Python mistake". I was writing the app in a language I wasn't very familiar with (just like when I was learning Python at that mom ent), and I wasn't happy with the code. It felt like spaghetti code all the time.

So, I made a complete U-turn and started over, this time using Golang. While I'm not as proficient in Golang as I am in Python now, I find it to be a very enjoyable language to code with. Most aof my recent pr ojects have been written in Golang, and I'm getting the hang of it. I tried to make the best decisions I could and structure the code as well as possible. Of course, there's still room for improvement, which I'll address in future updates.

Now I have a more maintainable website that can scale much better. It uses a real database instead of a JSON file like the old site, and I can add many more features. Since I chose to go with Golang, I mad e the "tradeoff" of not using JavaScript at all, so all the rendering load falls on the server. But I believe it's a tradeoff that's worth it.

What's new

• UI/UX - I've designed a new logo and color palette for kycnot.me. I think it looks pretty cool and cypherpunk. I am not a graphic designer, but I think I did a decent work and I put a lot of thinking on it to make it pleasant!
• Point system - The new point system provides more detailed information about the listings, and can be expanded to cover additional features across all services. Anyone can request a new point!
• ToS Scrapper: I've implemented a powerful automated terms-of-service scrapper that collects all the ToS pages from the listings. It saves you from the hassle of reading the ToS by listing the lines that are suspiciously related to KYC/AML practices. This is still in development and it will improve for sure, but it works pretty fine right now!
• Search bar - The new search bar allows you to easily filter services. It performs a full-text search on the Title, Description, Category, and Tags of all the services. Looking for VPN services? Just search for "vpn"!
• Transparency - To be more transparent, all discussions about services now take place publicly on GitLab. I won't be answering any e-mails (an auto-reply will prompt to write to the corresponding Gitlab issue). This ensures that all service-related matters are publicly accessible and recorded. Additionally, there's a real-time audits page that displays database changes.
• Listing Requests - I have upgraded the request system. The new form allows you to directly request services or points without any extra steps. In the future, I plan to enable requests for specific changes to parts of the website.
• Lightweight and fast - The new site is lighter and faster than its predecessor!
• Tor and I2P - At last! kycnot.me is now officially on Tor and I2P!

How?

This rewrite has been a labor of love, in the end, I've been working on this for more than 3 months now. I don't have a team, so I work by myself on my free time, but I find great joy in helping people on their private journey with cryptocurrencies. Making it easier for individuals to use cryptocurrencies without KYC is a goal I am proud of!

If you appreciate my work, you can support me through the methods listed here. Alternatively, feel free to send me an email with a kind message!

Technical details

All the code is written in Golang, the website makes use of the chi router for the routing part. I also make use of BigCache for caching database requests. There is 0 JavaScript, so all the rendering load falls on the server, this means it needed to be efficient enough to not drawn with a few users since the old site was reporting about 2M requests per month on average (note that this are not unique users).

The database is running with mariadb, using gorm as the ORM. This is more than enough for this project. I started working with an sqlite database, but I ended up migrating to mariadb since it works better with JSON.

The scraper is using chromedp combined with a series of keywords, regex and other logic. It runs every 24h and scraps all the services. You can find the scraper code here.

The frontend is written using Golang Templates for the HTML, and TailwindCSS plus DaisyUI for the CSS classes framework. I also use some plain CSS, but it's minimal.

The requests forms is the only part of the project that requires JavaScript to be enabled. It is needed for parsing some from fields that are a bit complex and for the "captcha", which is a simple Proof of Work that runs on your browser, destinated to avoid spam. For this, I use mCaptcha.

Bitcoin enthusiasts frequently and correctly remark how much value it adds to Bitcoin not to have a face, a leader, or a central authority behind it. This particularity means there isn't a single person to exert control over, or a single human point of failure who could become corrupt or harmful to the project.

Because of this, it is said that no other coin can be equally valuable as Bitcoin in terms of decentralization and trustworthiness. Bitcoin is unique not just for being first, but also because of how the events behind its inception developed. This implies that, from Bitcoin onwards, any coin created would have been created by someone, consequently having an authority behind it. For this and some other reasons, some people refer to Bitcoin as "The Immaculate Conception".

While other coins may have their own unique features and advantages, they may not be able to replicate Bitcoin's community-driven nature. However, one other cryptocurrency shares a similar story of mystery behind its creation: Monero.

History of Monero

Bytecoin and CryptoNote

In March 2014, a Bitcointalk thread titled "Bytecoin. Secure, private, untraceable since 2012" was initiated by a user under the nickname "DStrange"^1^. DStrange presented Bytecoin (BCN) as a unique cryptocurrency, in operation since July 2012. Unlike Bitcoin, it employed a new algorithm known as CryptoNote.

DStrange apparently stumbled upon the Bytecoin website by chance while mining a dying bitcoin fork, and decided to create a thread on Bitcointalk^1^. This sparked curiosity among some users, who wondered how could Bytecoin remain unnoticed since its alleged launch in 2012 until then^2^.

Some time after, a user brought up the "CryptoNote v2.0" whitepaper for the first time, underlining its innovative features^4^. Authored by the pseudonymous Nicolas van Saberhagen in October 2013, the CryptoNote v2 whitepaper^5^ highlighted the traceability and privacy problems in Bitcoin. Saberhagen argued that these flaws could not be quickly fixed, suggesting it would be more efficient to start a new project rather than trying to patch the original^5^, an statement simmilar to the one from Satoshi Nakamoto^6^.

Checking with Saberhagen's digital signature, the release date of the whitepaper seemed correct, which would mean that Cryptonote (v1) was created in 2012^7^, although there's an important detail: "Signing time is from the clock on the signer's computer" ^9^.

Moreover, the whitepaper v1 contains a footnote link to a Bitcointalk post dated May 5, 2013^10^, making it impossible for the whitepaper to have been signed and released on December 12, 2012.

As the narrative developed, users discovered that a significant 80% portion of Bytecoin had been pre-mined^11^ and blockchain dates seemed to be faked to make it look like it had been operating since 2012, leading to controversy surrounding the project.

The origins of CryptoNote and Bytecoin remain mysterious, leaving suspicions of a possible scam attempt, although the whitepaper had a good amount of work and thought on it.

The fork

In April 2014, the Bitcointalk user thankful_for_today, who had also participated in the Bytecoin thread^12^, announced plans to launch a Bytecoin fork named Bitmonero^13^.

The primary motivation behind this fork was "Because there is a number of technical and marketing issues I wanted to do differently. And also because I like ideas and technology and I want it to succeed"^14^. This time Bitmonero did things different from Bytecoin: there was no premine or instamine, and no portion of the block reward went to development.

However, thankful_for_today proposed controversial changes that the community disagreed with. Johnny Mnemonic relates the events surrounding Bitmonero and thankful_for_today in a Bitcointalk comment^15^:

When thankful_for_today launched BitMonero [...] he ignored everything that was discussed and just did what he wanted. The block reward was considerably steeper than what everyone was expecting. He also moved forward with 1-minute block times despite everyone's concerns about the increase of orphan blocks. He also didn't address the tail emission concern that should've (in my opinion) been in the code at launch time. Basically, he messed everything up. Then, he disappeared.

After disappearing for a while, thankful_for_today returned to find that the community had taken over the project. Johnny Mnemonic continues:

I, and others, started working on new forks that were closer to what everyone else was hoping for. [...] it was decided that the BitMonero project should just be taken over. There were like 9 or 10 interested parties at the time if my memory is correct. We voted on IRC to drop the "bit" from BitMonero and move forward with the project. Thankful_for_today suddenly resurfaced, and wasn't happy to learn the community had assumed control of the coin. He attempted to maintain his own fork (still calling it "BitMonero") for a while, but that quickly fell into obscurity.

The unfolding of these events show us the roots of Monero. Much like Satoshi Nakamoto, the creators behind CryptoNote/Bytecoin and thankful_for_today remain a mystery^17^, having disappeared without a trace. This enigma only adds to Monero's value.

Since community took over development, believing in the project's potential and its ability to be guided in a better direction, Monero was given one of Bitcoin's most important qualities: a leaderless nature. With no single face or entity directing its path, Monero is safe from potential corruption or harm from a "central authority".

The community continued developing Monero until today. Since then, Monero has undergone a lot of technological improvements, migrations and achievements such as RingCT and RandomX. It also has developed its own Community Crowdfundinc System, conferences such as MoneroKon and Monerotopia are taking place every year, and has a very active community around it.

Monero continues to develop with goals of privacy and security first, ease of use and efficiency second. ^16^

This stands as a testament to the power of a dedicated community operating without a central figure of authority. This decentralized approach aligns with the original ethos of cryptocurrency, making Monero a prime example of community-driven innovation. For this, I thank all the people involved in Monero, that lead it to where it is today.

If you find any information that seems incorrect, unclear or any missing important events, please contact me and I will make the necessary changes.

A new study by Kraken reveals how cryptocurrency investors perceive security as the main challenge in self-managing their digital assets.

According to The Block, a recent survey conducted by crypto exchange Kraken found that nearly half of respondents consider themselves the primary risk factor for their own crypto security. The research, which surveyed 789 participants, highlights that 48% of users see their own actions as the greatest threat to their investments in digital assets, surpassing concerns about external theft or fraud.

Kraken’s report underlines how personal responsibility in security management forces users to take full control of their digital funds. However, the study suggests that this autonomy can also become a source of anxiety for many investors.

Nick Percoco, Chief Security Officer at Kraken, commented on the findings, noting that “a lack of confidence in personal crypto security is capping the growth of the industry.” According to Percoco, unlocking the full potential of cryptocurrencies will require users to embrace self-custody and consistently invest in strong security habits.

Technologies to strengthen security

Despite the concerns highlighted in the study, 31% of participants expressed optimism about future technologies that could improve crypto security. Among the most promising solutions identified:

• advanced biometric systems for user authentication;
• multi-factor authentication to secure wallet access;
• AI-based fraud detection systems to prevent attacks.

Data and case studies

Kraken’s research emerges in a context where security threats remain a pressing reality. FBI data shows that in 2024, nearly 150,000 reports of crypto-related internet fraud resulted in $9.3 billion in losses. Older users, particularly those over 60, proved especially vulnerable, accounting for $3 billion in crypto-related financial fraud losses on their own.

Carl Rickertsen completely exits his position in Strategy as insiders sell $864 million worth of stock.

As reported by Protos, Carl Rickertsen, a member of Strategy’s board of directors, has fully liquidated his entire shareholding for over $10 million.

Rickertsen’s decision to completely exit his Strategy position marks a sharp shift from his previous investment stance. In 2022, the executive had shown confidence in the company by investing $700,000 in MSTR shares.

On June 13, 2022, Rickertsen purchased $608,000 worth of MSTR stock at $152 per share. Since then, the stock has rallied 152%. However, by 2023, the director had already sold half of his 4,000-share position.

Rickertsen’s approach to managing his holdings has become increasingly aggressive in recent years. Since joining the board in 2019, he has adopted a strategy of immediately liquidating any stock options received.

One example of this tactic occurred on June 2, when he acquired and sold 26,390 MSTR shares on the same day.

As of June 5 this year, Rickertsen reported zero vested Strategy shares, marking the end of his equity involvement with the company.

Rickertsen’s situation is not an isolated case within Strategy. Data from the Securities and Exchange Commission (SEC) reveals a controversial picture. According to information gathered by secform4.com, over the past five years, total insider sales have exceeded purchases by $864 million. This imbalance in insider transactions could raise questions about executives’ confidence in the company’s future.

Flash Releases Free Bitcoin Invoicing Tool with No Fees, KYC, or Custody

Flash, a Bitcoin payment platform, just announced it has launched Flash Invoicing, a completely free, non-custodial, and KYC-free Bitcoin invoicing tool. Designed for freelancers, the platform allows users to send professional invoices without platform fees, identity checks, or third party custody.

According to Deel, a crypto payments company for freelancers, Bitcoin is the most used cryptocurrency in the world for payments. Despite this growth, many freelancers continue to use basic methods such as pasting Bitcoin addresses into PDFs or emails. Some rely on custodial platforms that deduct fees or require identity verification, which can affect both earnings and data privacy.

“We’ve seen too many people paste BTC addresses into documents and call it invoicing,” said the CEO of Flash Pierre Corbin. “It’s messy. It’s risky. And it’s time for something better.” 

Flash Invoicing Features:

• 0% platform fees: no subscriptions or commission
• Non-custodial: Bitcoin goes straight to the user’s wallet
• No KYC: users maintain full privacy
• Professional output: branded PDFs and secure payment links
• Integrated dashboard: manage payments, clients, and revenue
• Works with Flash ecosystem: including Stores, Donations, Paywalls, and POS

Many Bitcoin invoicing tools charge a percentage per transaction or require a subscription. As a result, freelancers often lose part of their income simply to issue an invoice and receive payment. Flash is aiming to solve this issue.

“Freelancers work hard enough. The last thing they need is a platform skimming off their earnings,” said Corbin. “That’s why we dropped our fee from 1.5% to 0% — and launched the first invoicing tool that’s truly free, without compromising on privacy or control.”

Flash Invoicing allows users to accept Bitcoin payments without relinquishing control, privacy, or revenue. It is integrated with the broader Flash suite, enabling users to manage invoicing alongside features such as setting up stores, receiving donations, or gating premium content.

“As a freelancer myself, I love using the Flash invoicing feature,” stated a freelancer & Flash user. ”It keeps all my clients in one place, allows me to easily edit invoices and track payments. Much more professional than sending a lightning address in the footer of a PDF invoice.”

This post Flash Releases Free Bitcoin Invoicing Tool with No Fees, KYC, or Custody first appeared on Bitcoin Magazine and is written by Oscar Zarraga Perez.

Bitcoin foi criado para oferecer uma alternativa segura e descentralizada ao dinheiro tradicional, permitindo transações financeiras sem a necessidade de intermediários. DeFi, por outro lado, surgiu como uma expansão deste conceito, propondo serviços financeiros descentralizados, como empréstimos, trocas e geração de rendimento. No entanto, apesar das promessas de inovação, DeFi apresenta inúmeros riscos, tornando-se uma aposta perigosa para quem valoriza a segurança do seu Bitcoin.

O que é DeFi?

DeFi refere-se a um conjunto de aplicações financeiras que funcionam sem a intermediação de bancos ou instituições tradicionais. Estas plataformas utilizam contratos inteligentes para automatizar transações, permitindo que qualquer pessoa aceda a serviços financeiros sem depender de terceiros. Na teoria, DeFi promete mais liberdade financeira, mas na prática está cheio de riscos, fraudes e vulnerabilidades técnicas que podem comprometer os fundos dos utilizadores.

Os riscos de DeFi para quem tem Bitcoin

Bitcoin é a moeda digital mais segura do mundo, protegida por uma rede descentralizada e resistente à censura. Ao contrário de DeFi, que ainda está em fase experimental e já sofreu inúmeros ataques, Bitcoin mantém-se sólido e confiável. Quando alguém coloca Bitcoin em plataformas DeFi, está a abrir mão da segurança da sua custódia direta e a confiar em sistemas mais frágeis. os principais riscos incluem:

Hackers e falhas de código: contratos inteligentes são escritos por programadores e podem conter falhas que permitem roubos massivos. ao longo dos anos, milhares de milhões de dólares já foram perdidos devido a vulnerabilidades em plataformas DeFi.

Riscos de liquidação: muitas aplicações DeFi funcionam com sistemas de colateralização, onde os utilizadores bloqueiam Bitcoin para obterem empréstimos. se o mercado se tornar volátil, esses Bitcoins podem ser liquidados a preços abaixo do esperado, causando perdas irreversíveis.

Fraudes e rug pulls: DeFi está repleto de projetos obscuros onde os criadores desaparecem com os fundos dos utilizadores. sem regulamentação e sem garantias, quem deposita Bitcoin nessas plataformas pode nunca mais recuperar os seus fundos.

Guardar Bitcoin em segurança é a melhor escolha

Bitcoin foi criado para ser auto-custodiado, ou seja, cada utilizador deve ter controlo direto sobre os seus fundos sem depender de terceiros. Ao enviar Bitcoin para plataformas DeFi, perde-se essa segurança e expõe-se o ativo a riscos desnecessários. A melhor forma de proteger Bitcoin é armazená-lo numa carteira segura, preferencialmente offline (cold storage), evitando qualquer tipo de exposição a contratos inteligentes ou sistemas vulneráveis.

Resumindo, DeFi pode parecer inovador, mas os riscos superam largamente os potenciais benefícios, especialmente para quem valoriza a segurança de Bitcoin. ao invés de arriscar perder fundos em plataformas inseguras, o mais sensato é manter Bitcoin armazenado de forma segura, garantindo a sua preservação a longo prazo. Enquanto Bitcoin continua a ser a melhor reserva de valor digital do mundo, DeFi ainda se revela um ambiente instável e perigoso, onde poucos saem ganhadores e muitos acabam por perder.

Read the original blog post

After almost 3 months of work, we've completed the redesign of kycnot.me. More modern and with many new features.

Privacy remains the foundation - everything still works with JavaScript disabled. If you enable JS, you will get some nice-to-have features like lazy loading and smoother page transitions, but nothing essential requires it.

User Accounts

We've introduced user accounts that require zero personal information:

• Secret user tokens - no email, no phone number, no personal data
• Randomly generated usernames for default privacy and fairness
• Karma system that rewards contributions and unlocks features: custom display names, profile pictures, and more.

Reviews and Community Discussions

On the previous sites, I was using third party open source tools for the comments and discussions. This time, I've built my own from scratch, fully integrated into the site, without JavaScript requirements.

Everyone can share their experiences and help others make informed decisions:

• Ratings: Comments can have a 1-5 star rating attached. You can have one rating per service and it will affect the overall user score.
• Discussions: These are normal comments, you can add them on any listed service.

Comment Moderation

I was strugling to keep up with moderation on the old site. For this, we've implemented an AI-powered moderation system that:

• Auto-approves legitimate comments instantly
• Flags suspicious content for human review
• Keeps discussions valuable by minimizing spam

The AI still can mark comments for human review, but most comments will get approved automatically by this system. The AI also makes summaries of the comments to help you understand the overall sentiment of the community.

Powerful Search & Filtering

Finding exactly what you need is now easier:

• Advanced filtering system with many parameters. You can even filter by attributes to pinpoint services with specific features.

The results are dynamic and shuffle services with identical scores for fairness.

See all listings

Listings are now added as 'Community Contributed' by default. This means that you can still find them in the search results, but they will be clearly marked as such.

Updated Scoring System

New dual-score approach provides more nuanced service evaluations:

• Privacy Score: Measures how well a service protects your personal information and data

• Trust Score: Assesses reliability, security, and overall reputation

• Combined into a weighted Overall Score for quick comparisons

• Completely transparent and open source calculation algorithm. No manual tweaking or hidden factors.

AI-Powered Terms of Service Analysis

Basically, a TLDR summary for Terms of Service:

• Automated system extracts the most important points from complex ToS documents
• Clear summaries
• Updated monthly to catch any changes

The ToS document is hashed and only will be updated if there are any changes.

Service Events and Timelines

Track the complete history of any service, on each service page you can see the timeline of events. There are two types of events:

• Automatic events: Created by the system whenever something about a service changes, like its description, supported currencies, attributes, verification status…
• Manual events: Added by admins when there’s important news, such as a service going offline, being hacked, acquired, shut down, or other major updates.

There is also a global timeline view available at /events

Notification System

Since we now have user accounts, we built a notifiaction system so you can stay informed about anything:

• Notifications for comment replies and status changes
• Watch any comment to get notified for new replies.
• Subscribe to services to monitor events and updates
• Notification customization.

Coming soon: Third-party privacy-preserving notifications integration with Telegram, Ntfy.sh, webhooks...

Service Suggestions

Anyone with an account can suggest a new service via the suggestion form. After submitting, you'll receive a tracking page where you can follow the status of your suggestion and communicate directly with admins.

All new suggestions start as "unlisted" — they won't appear in search results until reviewed. Our team checks each submission to ensure it's not spam or inappropriate. If similar services already exist, you'll be shown possible duplicates and can choose to submit your suggestion as an edit instead.

You can always check the progress of your suggestion, respond to moderator questions, and see when it goes live, everything will also be notified to your account. This process ensures high-quality listings and a collaborative approach to building the directory.

---

These are some of the main features we already have, but there are many more small changes and improvements that you will find when using the site.

What's Next?

This is just the beginning. We will be constantly working to improve KYCnot.me and add more features that help you preserve your privacy.

Remember: True financial freedom requires the right to privacy. Stay KYC-free!

O Bitcoin trouxe uma nova maneira de entender a economia monetária, rompendo com os modelos inflacionários das moedas tradicionais e apresentando uma estrutura deflacionária especial. Com uma oferta restrita e regras matemáticas claras, o Bitcoin proporciona previsibilidade, segurança e resistência a manipulações, características que atraem investidores e fãs ao redor do mundo.

Um dos aspectos mais importantes do Bitcoin é sua oferta limitada a 21 milhões de unidades, definida no código original por Satoshi Nakamoto. Essa característica separa o Bitcoin das moedas tradicionais, cuja oferta é ilimitada e muitas vezes aumentada por bancos centrais para atender a necessidades econômicas ou políticas.

A oferta limitada dá ao Bitcoin uma qualidade semelhante ao ouro, sendo frequentemente chamado de "ouro digital". Assim como o ouro, o Bitcoin é escasso e requer esforço para ser adquirido (por meio de mineração). A escassez programada cria uma dinâmica de oferta e demanda que tende a aumentar o valor do ativo à medida que a demanda cresce e a oferta se mantém constante.

A emissão de novos bitcoins acontece através da mineração, e as recompensas são reduzidas pela metade em eventos chamados halvings, que ocorrem aproximadamente a cada quatro anos. Essa diminuição gradual na emissão de novos bitcoins assegura que a quantidade total será alcançada por volta de 2140, tornando o Bitcoin previsível a longo prazo.

O modelo deflacionário do Bitcoin é definido pela diminuição na criação de novas unidades e pelo aumento potencial de seu valor com o tempo. Isso contrasta diretamente com o modelo inflacionário das moedas tradicionais, nas quais a oferta é constantemente aumentada, reduzindo seu poder de compra.

A deflação no Bitcoin acontece porque a oferta de novos bitcoins diminui enquanto a demanda global tende a aumentar. Em vez de perder poder de compra, como ocorre com moedas tradicionais, o Bitcoin tem potencial de valorização à medida que mais pessoas buscam guardá-lo como valor.

Economias que dependem de sistemas deflacionários enfrentam desafios, como a tendência dos consumidores de adiar gastos na expectativa de preços mais baixos. Contudo, no caso do Bitcoin, ele é visto principalmente como uma reserva de valor, diminuindo esse efeito negativo. Por outro lado, o modelo deflacionário estimula a poupança, protegendo a riqueza das pessoas contra desvalorizações arbitrárias.

O modelo inflacionário das moedas fiduciárias se baseia na ampliação da oferta monetária para impulsionar o crescimento econômico, o que, na prática, reduz o poder de compra das moedas ao longo do tempo.

Governos e bancos centrais frequentemente imprimem dinheiro para pagar dívidas ou estimular a economia, o que pode resultar em inflação descontrolada.

Esse aumento na quantidade de dinheiro diminui o valor do dinheiro já existente, prejudicando poupadores e pessoas com menos acesso a ativos que protejam contra a inflação.

Como o Bitcoin é descentralizado e funciona em uma rede pública, nenhuma entidade central pode mudar suas regras ou aumentar sua oferta.

Isso o torna um ativo confiável para quem quer proteger sua riqueza em economias instáveis ou inflacionárias.

De maneira resumida a economia do Bitcoin é principalmente movida pela interação entre oferta e demanda.

O aumento da aceitação global, tanto por investidores institucionais quanto por indivíduos, gerou maior demanda pelo Bitcoin.

Sua utilidade como reserva de valor e defesa contra inflação atrai pessoas de economias frágeis e investidores em busca de diversificação.

Cada halving reduz a criação de novos bitcoins, diminuindo a oferta no mercado. Historicamente, esses eventos têm sido seguidos por aumentos significativos no preço do Bitcoin, pois a oferta menor atende a uma demanda crescente.

Com a oferta limitada e um cronograma previsível de emissão, o Bitcoin funciona de maneira clara, evitando surpresas econômicas comuns em sistemas fiduciários manipulados por bancos centrais.

Com o tempo, o Bitcoin pode ter um papel cada vez mais importante na economia global. Seu modelo deflacionário é especialmente atraente em um contexto de crescente desconfiança em relação às moedas fiduciárias e aos sistemas financeiros tradicionais.

O Bitcoin está se estabelecendo como uma reserva de valor, parecido com o ouro, mas com vantagens em portabilidade e divisibilidade.

Em períodos de crise econômica, ele é visto como uma alternativa segura para proteger riquezas.

À medida que a recompensa pela mineração diminui, espera-se que as taxas de transação sustentem a rede, aumentando sua segurança sem afetar a economia dos usuários.

Resumindo, a economia do Bitcoin é uma inovação que desafia os conceitos estabelecidos pelas moedas fiduciárias. Com sua oferta limitada, modelo deflacionário e resistência à manipulação, ele oferece uma alternativa forte para proteger a riqueza contra os efeitos da inflação.

Apesar de enfrentar desafios, como volatilidade e aceitação global, o Bitcoin continua a se fortalecer como uma reserva de valor confiável e uma forma de dinheiro digital. Seu modelo econômico, baseado na escassez e na transparência, pode ter um impacto duradouro na forma como pessoas e instituições lidam com o armazenamento e a preservação de valor no século XXI.

O Bitcoin é amplamente reconhecido como a primeira e mais importante inovação no campo das moedas digitais. Criado por Satoshi Nakamoto em 2009, ele estabeleceu as bases para um sistema financeiro descentralizado. Desde então, surgiram milhares de outras moedas digitais, muitas vezes referidas como criptomoedas ou até mesmo "shitcoins" por críticos que apontam sua volatilidade, falta de utilidade clara ou centralização. Essa comparação entre o Bitcoin e outras criptomoedas é essencial para entender os valores exclusivos que o Bitcoin representa.

O Bitcoin foi criado para ser uma alternativa ao sistema financeiro tradicional. Sua missão central é fornecer uma moeda descentralizada, resistente à censura e livre de intermediários como bancos ou governos.

Por outro lado, a maioria das outras criptomoedas/shitcoins surgiu com diferentes objetivos, que vão desde experimentos tecnológicos até planos de enriquecimento rápido. Muitas dessas moedas não têm a mesma descentralização e segurança do Bitcoin, sendo frequentemente geridas por equipes ou organizações centralizadas, o que as torna mais suscetíveis à manipulação e falhas de segurança.

Descentralização e segurança

Bitcoin: a rede Bitcoin é suportada por milhares de nós espalhados pelo mundo, garantindo verdadeira descentralização.

Seu algoritmo de consenso, Proof of Work (PoW), é amplamente testado e proporciona altos níveis de segurança contra ataques.

Não há controle centralizado, o que significa que nenhuma entidade pode alterar suas regras fundamentais.

Outras criptomoedas/shitcoins

Praticamente todas sacrificam descentralização em troca de velocidade ou funcionalidades adicionais.

Algumas utilizam mecanismos de consenso alternativos, como Proof of Stake (PoS), que, embora sejam mais eficientes em termos energéticos, são frequentemente criticados por favorecer a centralização e oferecer menor segurança.

Em muitos casos, há equipes de desenvolvimento centralizadas que podem modificar o código, criar mais unidades da moeda ou até encerrar o projeto, comprometendo a confiança dos usuários.

Oferta e escassez

Bitcoin: o Bitcoin tem uma quantidade limitada de 21 milhões de unidades, garantindo sua escassez.

Essa característica, junto com a crescente demanda, posiciona o Bitcoin como uma reserva de valor confiável, frequentemente comparado ao ouro digital.

Outras criptomoedas/shitcoins

Muitas não têm limites claros em sua oferta, resultando em inflação descontrolada.

Algumas “moedas” são intencionalmente inflacionárias, o que pode reduzir seu valor com o tempo.

Em muitos casos, essas “moedas” são pré-mineradas ou distribuídas de maneira desigual, favorecendo os criadores em detrimento da comunidade.

Finalidade e utilidade

Bitcoin: o Bitcoin é, acima de tudo, uma forma de dinheiro digital e reserva de valor.

Sua rede é confiável e simples, com o foco principal em ser um meio de troca e proteção contra a inflação.

Sua solidez o torna ideal para transações e armazenamento de valor a longo prazo.

Outras criptomoedas/shitcoins

Muitas shitcoins são apresentadas como soluções para casos específicos, como contratos inteligentes, jogos ou finanças descentralizadas.

Apesar de promessas ousadas, muitos falham em oferecer utilidade real ou em competir com soluções centralizadas já existentes.

Há um número considerável de projetos que não têm uma proposta clara e acabam sendo abandonados após um tempo de especulação.

Volatilidade e reputação

Bitcoin: embora o Bitcoin seja instável, ele é amplamente aceito como o padrão-ouro das moedas digitais.

Sua imagem foi construída ao longo de mais de dez anos de operação confiável e segurança comprovada.

Outras criptomoedas/shitcoins

Muitas shitcoins enfrentam alta volatilidade, frequentemente impulsionada por especulação ou manipulação de mercado.

A falta de clareza e as práticas duvidosas de alguns projetos prejudicam a imagem do setor como um todo.

Resistência à censura

Bitcoin: devido à sua descentralização e segurança, o Bitcoin é muito resistente à censura. Qualquer pessoa com acesso à internet pode participar da rede e fazer transações.

Outras criptomoedas/shitcoins

Muitas "shitcoins" dependem de estruturas centralizadas ou têm líderes identificáveis que podem ser pressionados por governos ou outros atores para censurar transações.

Resumindo, o Bitcoin continua sendo o líder indiscutível no mundo das moedas digitais devido à sua descentralização, segurança e escassez comprovada. Ele é um sistema feito para durar, oferecendo liberdade financeira e proteção contra a inflação.

Enquanto isso, muitas criptomoedas ou shitcoins não conseguem atingir os mesmos padrões de segurança e confiança, frequentemente priorizando velocidade, funções extras ou lucros especulativos rápidos. Para investidores e usuários, é importante distinguir entre o Bitcoin e os vários projetos alternativos, muitos dos quais podem não resistir ao teste do tempo.

O Bitcoin não só iniciou uma revolução financeira, mas continua sendo o padrão pelo qual todas as outras moedas digitais são medidas.

Muito obrigado por teres lido o texto até aqui, espero que esteja tudo bem contigo e um abraço enorme do teu madeirense bitcoiner maximalista favorito. Viva a liberdade!

No sistema Bitcoin, a proteção e a posse dos fundos são asseguradas por um modelo criptográfico que usa chaves privadas e públicas. Esses componentes são fundamentais para a segurança digital, permitindo que os usuários administrem e protejam seus ativos de maneira descentralizada. Esse processo elimina a necessidade de intermediários, assegurando que somente o legítimo proprietário tenha acesso ao saldo vinculado a um endereço específico na blockchain ou timechain.

Chaves privadas e públicas são partes de um sistema de criptografia assimétrica, onde dois códigos distintos, mas matematicamente ligados, são utilizados para garantir a segurança e a veracidade das transações.

Chave Privada = É um código secreto, normalmente apresentado como uma longa sequência de números e letras.

Funciona como uma senha que dá ao proprietário o controle sobre os bitcoins ligados a um endereço específico.

Deve ser mantida em total sigilo, pois qualquer pessoa que a tenha pode movimentar os fundos correspondentes.

Chave Pública = É matematicamente derivada da chave privada, mas não permite que a chave privada seja descoberta.

Funciona como um endereço digital, semelhante a um número de conta bancária, podendo ser compartilhada livremente para receber pagamentos.

Serve para confirmar a autenticidade das assinaturas geradas com a chave privada.

Juntas, essas chaves asseguram que as transações sejam seguras e verificáveis, dispensando a necessidade de intermediários.

O funcionamento das chaves privadas e públicas baseia-se na criptografia de curva elíptica. Quando um usuário quer enviar bitcoins, ele usa sua chave privada para assinar digitalmente a transação. Essa assinatura é exclusiva para cada operação e demonstra que o remetente possui a chave privada relacionada ao endereço de envio.

Os nós da rede Bitcoin checam essa assinatura utilizando a chave pública correspondente, garantindo que:

A assinatura é válida.

A transação não foi alterada desde que foi assinada.

O remetente tem a propriedade legítima dos fundos.

Se a assinatura for aceita, a transação é registrada na blockchain ou timechain e se torna irreversível. Esse procedimento protege os fundos contra fraudes e gastos duplicados.

A segurança das chaves privadas é um dos pontos mais importantes do sistema Bitcoin. Perder essa chave significa perder permanentemente o acesso aos fundos, pois não há nenhuma autoridade central capaz de recuperá-la.

Boas práticas para proteger a chave privada incluem:

Armazenamento offline: longe de redes conectadas à internet, diminuindo o risco de ataques cibernéticos.

Carteiras de hardware: dispositivos físicos dedicados para armazenar chaves privadas de forma segura.

Backup e redundância: manter cópias de segurança em locais seguros e distintos.

Criptografia adicional: proteger arquivos digitais que contêm chaves privadas com senhas fortes e criptografia.

Ameaças comuns incluem:

Phishing e malware: ataques que tentam enganar os usuários para obter acesso às chaves.

Roubo físico: no caso de chaves guardadas em dispositivos físicos.

Perda de senhas e backups: que pode resultar na perda definitiva dos fundos.

O uso de chaves privadas e públicas dá ao proprietário controle total sobre seus fundos, eliminando intermediários como bancos ou governos. Esse modelo coloca a responsabilidade de proteção nas mãos do usuário, o que representa tanto liberdade quanto risco.

Diferente de sistemas financeiros tradicionais, onde instituições podem reverter transações ou congelar contas, no sistema Bitcoin, a posse da chave privada é a única prova de propriedade. Esse princípio é frequentemente resumido pela frase: "Not your keys, not your coins" (Se não são suas chaves, não são suas moedas).

Essa abordagem fortalece a soberania financeira, permitindo que indivíduos guardem e movam valor de maneira independente e sem censura.

Apesar de sua segurança, o sistema de chaves também apresenta riscos. Se uma chave privada for perdida ou esquecida, não existe como recuperar os fundos associados. Isso já levou à perda de milhões de bitcoins ao longo dos anos.

Para reduzir esse risco, muitos usuários utilizam frases-semente (seed phrases), que são uma lista de palavras usadas para restaurar carteiras e chaves privadas. Essas frases devem ser guardadas com o mesmo cuidado, pois também podem ser usadas para acessar os fundos.

Resumindo, as chaves privadas e públicas são a base da segurança e da propriedade no sistema Bitcoin. Elas asseguram que somente os verdadeiros proprietários possam mover seus fundos, promovendo um sistema financeiro descentralizado, seguro e resistente à censura.

No entanto, essa liberdade acarreta grandes responsabilidades, exigindo que os usuários adotem práticas severas para proteger suas chaves privadas. A perda ou comprometimento dessas chaves pode levar a consequências irreversíveis, ressaltando a importância de educação e preparação ao usar o sistema Bitcoin.

Assim, o modelo de chaves criptográficas não apenas melhora a segurança, mas também representa a essência da independência financeira proporcionada pelo Bitcoin.

Carl Rickertsen completely exits his position in Strategy as insiders sell $864 million worth of stock.

As reported by Protos, Carl Rickertsen, a member of Strategy’s board of directors, has fully liquidated his entire shareholding for over $10 million.

Rickertsen’s decision to completely exit his Strategy position marks a sharp shift from his previous investment stance. In 2022, the executive had shown confidence in the company by investing $700,000 in MSTR shares.

On June 13, 2022, Rickertsen purchased $608,000 worth of MSTR stock at $152 per share. Since then, the stock has rallied 152%. However, by 2023, the director had already sold half of his 4,000-share position.

Rickertsen’s approach to managing his holdings has become increasingly aggressive in recent years. Since joining the board in 2019, he has adopted a strategy of immediately liquidating any stock options received.

One example of this tactic occurred on June 2, when he acquired and sold 26,390 MSTR shares on the same day.

As of June 5 this year, Rickertsen reported zero vested Strategy shares, marking the end of his equity involvement with the company.

Rickertsen’s situation is not an isolated case within Strategy. Data from the Securities and Exchange Commission (SEC) reveals a controversial picture. According to information gathered by secform4.com, over the past five years, total insider sales have exceeded purchases by $864 million. This imbalance in insider transactions could raise questions about executives’ confidence in the company’s future.

Bitcoin Core Github page announced yesterday that Core Developers have merged pull request #32406, removing support for “-datacarrier” argument for Bitcoin Core software in their next release, expected to be published in October.

Pull request #32406 has been merged — Github

This is the latest development regarding the initiative brought forth by Bitcoin Core developer Peter Todd, which has caused intense debate among Bitcoiners, now known as the “spam wars”.

The disagreement is over a change to Bitcoin Core’s transaction relay policy that removes the OP_RETURN data limit, which some see as a threat to Bitcoin’s very purpose, while others see it as a necessary step to preserve decentralization and censorship resistance.

OP_RETURN is an arbitrary piece of data that can be amended to a bitcoin transaction, and used to be limited to 80 bytes. Users have found ways to go around this limit already and have uploaded larger data to the Bitcoin blockchain, including photos, audio, and even entire computer games.

Bitcoin Core allows for extra arguments when running the application, one of which is the “-datacarrier” argument, which tells the application to not accept transactions including larger OP_RETURN data into its mempool.

Now this argument is marked as “deprecated”, meaning it is not supported or developed anymore, and is expected to be completely removed in future versions.

This will make accepting Bitcoin transactions that contain non-financial data mandatory for anyone running future versions of the Core software.

Prior to the merging of the mentioned pull request on the morning of Monday June 9, a joint statement from 31 Bitcoin Core devs was released on June 6, reheating the already controversial debate in the Bitcoin community.

In the June 6 statement, Bitcoin Core devs explained how they think Bitcoin nodes should handle transactions that include non-financial data, like digital art or messages. This type of data has become more common with Ordinals and inscriptions.

Related: Discussions Heat Up Among Bitcoin Devs Over OP_RETURN Proposal

Core developers said they are not endorsing non-financial use of Bitcoin, but also won’t stop it. Their main point is that Bitcoin’s strength is in being open and censorship-resistant. They wrote:

“This is not endorsing or condoning non-financial data usage, but accepting that as a censorship-resistant system, Bitcoin can and will be used for use cases not everyone agrees on.”

They say it’s up to users and node operators to decide what kind of Bitcoin software they run. Bitcoin Core won’t block transactions that have economic demand and will be mined.

“Being free to run any software is the network’s primary safeguard against coercion,” the statement added.

The policy change goes back to a May 8th upgrade (announced by Core contributor and Engineer at Blockstream, Greg Sanders), where devs removed the long-standing 80-byte limit on OP_RETURN output size.

This limit was meant to discourage non-payment data usage, but devs say it no longer serves that purpose.

“Retiring a deterrent that no longer deters” makes sense, they argue, because people have already found ways to add large data to the blockchain.

They also point out that removing the cap may help miners and users more than it hurts. They claim the new approach helps predict which transactions will be mined, speeds up block propagation and helps miners find fee-paying transactions.

“Knowingly refusing to relay transactions that miners would include in blocks anyway forces users into alternate communication channels,” they explained, warning this could harm decentralization.

The response has been mixed.

The announcement of the merge received 64 upvotes and 93 downvotes from reviewers, showing the community is mostly against this action. Comments explaining their dissatisfaction with the merge also received the support of the majority.

Reviewers who voted ACK (acknowledgment and agreement) were downvoted, and the comments voting NACK (disagreement) received more upvotes.

Comments regarding the recent merge — Bitcoin Core Github page

Critics say it opens the door to blockchain spam, higher fees and more bloat on the blockchain with non-financial content. They say Bitcoin should stick to its original purpose as a “peer-to-peer electronic cash system”.

Samson Mow, CEO of JAN3, was one of the most vocal critics. He said the devs are removing the barriers that protect the network from spam.

“Bitcoin Core devs have been changing the network gradually to enable spam,” Mow said. “It’s disingenuous to just say ‘It is what it is now, too bad’.”

Bitcoin dev Luke Dashjr also criticized the move, saying it undermines Bitcoin’s core function. He called the devs’ goals “basically all wrong” and said expecting spam to be mined is “defeatism”.

Luke Dashjr on X

One user said: “It’s Bit”Coin” not Bit”Bucket” or Bit”Store” or whatever general purpose data store you have in mind. It’s a peer to peer electronic cash system”.

Another user chimed in, warning it could increase costs, reduce efficiency and even hurt long-term scalability.

Their argument is simple: if nonfinancial data is allowed to be stored on the blockchain, it will increase its size over time, storing useless data, and it will hurt decentralization, as fewer individuals will be able to host the entire blockchain on their computers.

They argue allowing people to store whatever they want on the blockchain because transactions shouldn’t be censored, will lead to hurting bitcoin in the long run. Many even argue no additional information should be allowed on the blockchain at all.

But not everyone is unhappy.

Some like Jameson Lopp, co-founder of Bitcoin wallet provider Casa, praised the devs for being transparent and consistent.

“Core Devs are a group saying we can’t force anyone to run code they don’t like,” Lopp said. “Here is our thinking on relay policy and network health.”

Lopp believes a joint statement helps the public understand what the devs stand for.

Supporters also say in a truly decentralized system, devs shouldn’t be gatekeepers. Instead users and miners should be able to decide what goes on the blockchain.

With opinions so divided, the future of Bitcoin may be more contentious. Some predict a fork to create a version of Bitcoin that only deals with monetary use. Others expect new wallet and node software that lets users choose to filter out large data or allow it.

Despite the controversy, the devs are standing by their decision. “While we recognize that this view isn’t held universally,” they said. “it is our sincere belief that it is in the best interest of Bitcoin and its users.”

Tired of dealing with spam? You're not alone. Here is a guide to picking relays that are good at keeping spam out, without sacrificing your own reach.

If you just want to skip to the relay suggestions, scroll to the sections titled "The Setup." There is one for users of Haven and one for those who aren't running their own relay at all.

Client Selection

"Wait, I thought this was a guide about selecting relays, not clients."

Yes, it is. But what relays you choose doesn't matter if you are using a client that does not read from your chosen relays, or that hard-codes problematic relays as fallbacks in addition to the relays you selected in an effort to "help you."

Additionally, some clients have settings that can help make up for poor relay selection using client-side spam mitigation methods. This includes clients like Coracle, Damus, Amethyst, and Nostur. Some may do so via web-of-trust (WoT) filters, so you only see notes and replies from those within your broader social circle, while others will automatically hide notes that those you follow have reported as spam or scams.

Coracle is a great client for dealing with spam, so long as you have gone into your "Content Settings" and set the "Minimum WoT Score" to at least 1. This means you will only see posts from users followed by at least one of the npubs you follow.

Damus also employs WoT, but it appears to be just for notifications, so you only receive notifications for those you follow and those they follow, or "friends of friends," as Damus put's it. This can be accessed by toggling it on in your notification tab at the top right, where you see the icon of the person with a check mark.

Nostur has WoT filters for downloading media turned on by default and also uses WoT to filter spam by default. Even better, if you use multiple npubs, you can filter using the WoT of your main npub, while logged into your alternate npubs.

Jumble recently added WoT filtering specifically for interactions. When you load a thread in Jumble, a shield icon will appear near the top right of the page, in line with the tabs for Replies and Quotes. Toggle it on, so the shield is green with a check mark and you will only see replies from those you follow and those your follows follow.

Amethyst does not yet have WoT based filtering built into the client, but it can hide notes that have been reported as spam, scams, impersonation, etc, by those you follow. This is not the most effective way to combat spam, though, since most users aren't often using the report feature. Hopefully we will see WoT filtering as an option in a future update.

Primal's apps do not read from any of your selected relays, but rather from their caching server alone. That said, they have a spam filter that is turned on by default so you see relatively little spam, regardless of which relays you use.

For this guide, I recommend using Amethyst for updating your relays, if you possibly can. The reason for this is because Amethyst has the most robust settings for being able to update all of your various relay lists.

Relay Lists Explained

Contrary to what you might think, there is not a single relay list for each user that is stored in a single note, because you can have relays that are used for only one purpose, and not for any other. Each of those purposes for which you might use a particular relay has its own list. That way a Nostr client can tell which relays you want to use for each separate purpose.

While this can make things less approachable for the user, it also means users don't have to rely on clients to hard code appropriate relays for each of these use-cases. If your client doesn't let you edit each of these relay lists, chances are they are using a set of relays for that purpose that the developer chose instead of you.

Public Outbox/Inbox Relays

This list of relays is found in your kind 10002 note, if you have one. If you don't have one, there won't be any relays shown for these categories in Amethyst. Other clients may fallback to showing you relays from a different list.

This list is intended to be used for Nostr clients to implement the "outbox model" to fetch notes from whatever relays they were written to, even if they aren't in the requesting user's relay list. This solves the issue of needing to share relays with those you follow in order to see their notes, allowing Nostr to remain decentralized.

Your "outbox" relays are the ones you write to, or at least the ones you want other users to know that you write to. When you add a relay here, it's like advertising to everyone, "If you want to see my public-facing notes, look for them on these relays."

Your "inbox" relays are the ones you read from. On this part of your list you are advertising, "If you want me to see your replies, comments, reactions, and zaps, then send them to these relays." These relays are massively important for reducing the amount of spam you see. If you have relays listed here that anyone can post to for free, you will almost certainly see a lot of spam in your replies, unless you have WoT filters turned on in your Nostr client.

DM Inbox Relays

This list is found in your kind 10050 note, if you have one, and is a list of relays where you want others to send you Direct Messages. Ideally, you will use a relay or two here that supports AUTH, so that it will only allow direct messages to be retrieved by the user they are addressed to.

What happens if you put a relay in here that doesn't support AUTH, so it allows anyone to retrieve your DMs? Not much. Anyone who wants to will just be able to see the encrypted content of the message, and depending on the type of DM they will see the identity of the receiver and perhaps also the sender. They will not be able to decrypt what was actually said in the messages. It's better if they cannot retrieve even that much, though.

Private Relays

This list is found in your 10013 note, if you have one. This is intended for listing a relay that you run yourself and that only you can access, as it will house notes that other users should not be able to see at all, such as eCash tokens and draft notes.

Search Relays

This list is found in your 10007 note, if you have one, and is used to search for notes or users who may not be using the same relays as you. It is good to use relays here that aggregate notes from other relays automatically, and which support NIP-50 for search capability.

Local Relays

This section is for any relays running on the local device, such as Citrine. Because the relays themselves are local, this list is local, as well, and is not saved to any note kind that is saved to your relays like the above lists.

General Relays

This list is found in the "content" tag of your kind 3 note, which is also where all of the npubs you follow are stored. As such, this note is commonly known as your follow list, rather than as a relay list. However, some clients, such as Amethyst, do make use of this list, and others use it as a fallback if they can't find a kind 10002.

If you are an Amethyst user most of the time, then I would recommend using this list to fill in any gaps that you may have from only writing to a few outbox relays, or only reading from a few inbox relays. It's a good place to put an aggregator relay, for instance, so long as that relay has good spam filtering, or a blastr relay, so those who don't yet use a client that supports the outbox model will still likely see your notes.

If you do not generally use Amethyst, then I would recommend you mirror your public inbox/outbox relays here, in case you use a client that cannot find your 10002 list. Relays that are only for outbox should be added as write only, those only for inbox should be added as read only, and those you use for both outbox and inbox should be both read and write.

The Setup (Haven Users)

If you are running your own set of Haven relays, here is the setup I would recommend:

Public Outbox (kind 10002)

Maximum of 4 relays.

• Your Haven outbox relay (Remember to add some public relays to your blastr)
• A paid relay of your choice (List available in "Paid Relays" section)
• A public relay, such as relay.damus.io, relay.primal.net, or nos.lol

Public Inbox (kind 10002)

Maximum of 4 relays.

• Your Haven inbox relay: [RelayAddress]/inbox
• A paid relay of your choice (can be same as outbox)
• A WoT relay of your choice (available in "WoT Relays" section)
• Optional additional WoT relay

DM Inbox

Maximum of 3 relays.

• Your Haven "chat" relay: [RelayAddress]/chat
• An alternate AUTH relay, such as inbox.nostr.wine(paid), nostr.land(paid), or auth.nostr1.com(free).

Private Relays

Maximum of 3 relays.

• Your Haven private relay: [RelayAddress]/private

Search Relays

Maximum of 4 relays.

• wss://nostr.wine (even if you don't pay to write to it)
• wss://relay.nostr.band
• wss://relay.noswhere.com
• wss://search.nos.today

Local Relays

• Your Citrine IP:Port, if you run Citrine.

General Relays

Assuming you use Amethyst on a regular basis, I recommend the following:

• A couple additional WoT relays set to read only.
• An aggregator relay that has good spam filtering, such as wss://aggr.nostr.land(payment required) and/or wss://nostr.wine(paid for write, but can read for free).

The Setup (Not Running Haven)

If you are not running your own set of Haven relays, I would highly recommend you learn how and do so. However, if you decide against it, here is a setup that should suffice:

Public Outbox (kind 10002)

Maximum of 4 relays.

• A paid relay of your choice (List available in "Paid Relays" section)
• A large public relay, such as relay.damus.io, relay.primal.net, or nos.lol
• An additional public relay, but a smaller one, or one-time-payment paid relay.

Public Inbox (kind 10002)

Maximum of 4 relays.

• A paid relay of your choice (can be same as outbox)
• wss://nostr.wine - Even if you don't pay for it, you can read from it.
• A WoT relay of your choice (available in "WoT Relays" section)
• Optional additional WoT relay

DM Inbox

Maximum of 3 relays.

• A paid AUTH relay, such as inbox.nostr.wine or nostr.land.
• An alternate AUTH relay, such as auth.nostr1.com(free).

Private Relays

Maximum of 3 relays.

• A private relay you run on your Umbrel or Start9, or that is hosted for you on relay.tools.

Search Relays

Maximum of 4 relays.

• wss://nostr.wine (even if you don't pay to write to it)
• wss://relay.nostr.band
• wss://relay.noswhere.com
• wss://search.nos.today

Local Relays

• Your Citrine IP:Port, if you run Citrine.

General Relays

Assuming you use Amethyst on a regular basis, I recommend the following:

• A couple additional WoT relays set to read only.
• An aggregator relay that has good spam filtering, such as wss://aggr.nostr.land(payment required).
• A blastr relay, such as filter.nostr.wine(paid), or...
• A few additional public relays set to write only.

Paid Relays

• wss://nostr.land - Details.
• The Nostr.Wine of relays.
  • wss://nostr.wine - Details
  • wss://filter.nostr.wine - Details
  • wss://inbox.nostr.wine -Details
  • wss://cellar.nostr.wine - Details
  • wss://creatr.nostr.wine - Details
• wss://jellyfish.land - Details

There are a ton of other paid relays out there that can be found via nostr.watch. The above listed options are simply the most popular with the largest feature-sets.

WoT Relays

These relays will only accept notes from npubs that are within the relay owner's WoT. I have provided a Jumble.social address for each relay so you can peruse the feed for yourself to see if you want to use it.

• wss://wot.utxo.one - Jumble Feed

@ b1ddb4d7:471244e7

That’s exactly what Simplified Privacy VPN is offering: a new kind of privacy tool that feels more like spinning up a secure, disposable virtual browser than using a traditional VPN.

Most of us know what a VPN is: it hides your IP address, encrypts your traffic, and gives you a bit more control over your privacy online. But what if you could go way beyond that—without setting up a complicated system, running a full virtual machine, or revealing anything about yourself?

What Makes It Different?

When I tried it myself, I realized this wasn’t just another VPN. It didn’t just route my traffic—it gave me access to a completely separate browsing environment. Imagine logging into a private, anonymous machine in the cloud, one that:

• Has its own browser and system settings
• Can’t see your personal files, history, or identity
• Randomizes details like screen size and timezone
• Leaves no trace once you’re done

This isn’t just hiding your IP—it’s giving you a fresh, secure web session that’s disconnected from your actual device.

Simplified Privacy VPN: The Lightning-Powered Twist

Here’s where it gets even cooler for us in the Lightning world: access costs just $1 in bitcoin via the Lightning Network.

You send a few sats, and within seconds you get access to a private browser session that lasts for a full month. Want a different profile or setup? Just pay another dollar and spin up a new one—no account, no email, no friction.

You can create as many instances as you like, each with its own identity. This is microtransaction-based privacy in action—exactly the kind of innovation Lightning enables.

Excellent Support, Secure Channels

I also tested their support team with a couple of questions—one technical issue and one feature request. Support is offered through secure, privacy-respecting channels, including Session chat. Responses were fast, friendly, and helpful. Even more impressive: my feature request was implemented not long after I sent it in.

In a space where many privacy tools leave you to figure things out on your own, this kind of responsive support makes a big difference.

Why This Matters

For journalists, activists, developers, or just regular folks who don’t want Big Tech watching their every move, this setup is a game-changer:

• More realistic protection than just using incognito mode or a VPN
• No need to trust the website, since this system isolates the browser to its own filesystem
• No need to trust the app, since it doesn’t require root access or your system password.
• Instant access with no signup or personal info
• Perfect match for Lightning’s low-cost, no-middleman model

One Note of Caution

While the system is impressive and genuinely different from anything I’ve seen, the project is still early and niche. The website and team aren’t as well-known as major VPN providers. So use it like any experimental tool—test it, learn from it, but don’t put all your trust in one basket yet.

Final Thoughts

In a world where online tracking is getting creepier and centralized control is tightening, SimplifiedPrivacy.com is pushing in the opposite direction: easy, user-controlled privacy with zero setup and lightning-fast access.

If you’ve got a dollar and a need for a little online invisibility, this might be one of the best ways to spend your sats.

The banking giant is exploring an expansion of its blockchain services, focusing on digital payments and currencies.

JPMorgan Chase has filed a new trademark application for the name “JPMD.” The filing was submitted on June 15 to the United States Patent and Trademark Office (USPTO).

The application, filed by JPMorgan Chase Bank, N.A., covers a broad range of services related to digital assets and blockchain technology. These include the issuance of digital currencies, electronic payment processing, and financial custody services — all of which suggest a possible new stablecoin initiative for JPMorgan.

Experience with JPM Coin

This move wouldn’t be JPMorgan’s first foray into blockchain-based finance. The bank already operates JPM Coin, a dollar-pegged stablecoin used to enable instant transactions between institutional clients. The token runs on Quorum, a private blockchain network developed in-house by JPMorgan and based on Ethereum’s technology.

The registration of the JPMD trademark comes as JPMorgan and other major U.S. banks are considering a collaborative stablecoin project through their jointly owned entities: Early Warning Services and The Clearing House.

Similarly, corporations like Walmart and Amazon are mulling the creation of their own stablecoins.

Ukraine Introduces Bill to Allow Bitcoin in National Reserves

Ukraine has introduced a bill that would give its central bank the legal right to hold Bitcoin and other assets as part of its national reserves. The draft law, submitted to the Verkhovna Rada on June 10, 2025, proposes updates to existing legislation to include “virtual assets” in the foreign exchange and gold reserves of the National Bank of Ukraine (NBU). 

NEW: Ukraine introduces bill for Bitcoin Reserve in Parliament pic.twitter.com/bYIiCNF13D

— Bitcoin Magazine (@BitcoinMagazine) June 17, 2025

This doesn’t mean Ukraine is officially adding Bitcoin to its balance sheet just yet, but it would give the central bank the green light to do so in the future.  

One of the bill’s co-sponsors, Member of Parliament Yaroslav Zhelezniak, emphasized that the legislation is about granting permission, not making it a requirement. “Whether and to what extent they actually do so,” he said, “is up to the institution itself.” 

Zhelezniak recently discussed with Binance’s regional head Kyrylo Khomiakov, that he believes Bitcoin could help Ukraine strengthen its economic position and contribute to long term digital innovation. 

The timing of the bill is vital as Ukraine has been under enormous financial pressure since Russia’s invasion in 2022. Inflation remains high, the hryvnia has lost significant value, and the country is heavily reliant on international aid and loans. The NBU has managed to hold roughly $44.5 billion in reserves, mostly in U.S. dollars and government securities, but its room to maneuver is limited.  

Back in 2022, the Ukrainian government was actively raising donations for the war effort through Bitcoin. They had an official wallet set up for donations, and their politicians were publicly tweeting out the addresses asking for support. On the first day alone, Ukraine’s official Bitcoin wallet raised over $3.5 million. By leaning into Bitcoin during their time of crisis, the government showed their belief and commitment in it, and this new bill shows that that commitment has not faded.

If this bill is adopted, it could position Ukraine as one of the first countries to give its central bank the legal ability to hold Bitcoin as a strategic reserve asset.

A rede Bitcoin é formada por uma infraestrutura descentralizada feita de dispositivos chamados nós. Esses nós têm um papel crucial na validação, verificação e manutenção do sistema, assegurando a segurança e a integridade do blockchain ou timechain. Ao contrário dos sistemas tradicionais, onde uma autoridade central controla as operações, a rede Bitcoin requer a colaboração de milhares de nós pelo mundo, promovendo descentralização e transparência.

Na rede Bitcoin, um nó é qualquer computador que está conectado ao sistema e participa do armazenamento, validação ou distribuição de informações. Esses dispositivos rodam o software do Bitcoin e podem operar em diferentes níveis de participação, desde tarefas básicas de transmissão de dados até a validação total de transações e blocos.

Existem dois tipos principais de nós:

Nós completos (full nodes):

Armazenam uma cópia total do blockchain ou timechain.

Validam e verificam todas as transações e blocos de acordo com as regras do protocolo.

Asseguram a segurança da rede ao rejeitar transações inválidas ou tentativas de fraude.

Nós leves (light nodes):

Armazenam somente partes do blockchain ou timechain, não a estrutura inteira.

Confiam em nós completos para obter dados sobre o histórico de transações.

São mais rápidos e menos exigentes em termos de recursos, mas dependem de terceiros para validação completa.

Os nós conferem se as transações enviadas seguem as regras do protocolo, como assinaturas digitais válidas e ausência de gastos duplos.

Somente transações válidas são enviadas para outros nós e incluídas no próximo bloco.

Os nós completos mantêm uma cópia atualizada de todo o histórico de transações da rede, garantindo integridade e transparência e se houver discrepâncias, os nós seguem a cadeia mais longa e válida, evitando manipulações.

Os nós transmitem informações de transações e blocos para outros nós na rede. Esse processo assegura que todos os participantes estejam sincronizados e atualizados.

Como a rede Bitcoin é composta por milhares de nós independentes, é quase impossível que um único agente controle ou modifique o sistema.

Os nós também protegem contra ataques ao validar informações e barrar tentativas de fraudes.

Os nós completos são muito importantes, pois atuam como auditores independentes. Eles não precisam de terceiros e podem verificar todo o histórico de transações diretamente.

Ao manterem uma cópia completa do blockchain ou timechain, esses nós permitem que qualquer pessoa valide transações sem depender de intermediários, promovendo clareza e liberdade financeira.

Além disso, os nós completos:

Reforçam a resistência à censura: Nenhum governo ou entidade pode excluir ou alterar dados registrados no sistema.

Preservam a descentralização: Quanto mais nós completos existirem, mais segura e forte será a rede.

Aumentam a confiança no sistema: Os usuários podem confirmar de forma independente se as regras estão sendo seguidas.

Apesar de seu valor, operar um nó completo pode ser difícil, pois exige espaço de armazenamento, processamento e largura de banda. À medida que o blockchain ou timechain cresce, os requisitos técnicos aumentam, o que pode dificultar a participação de usuários comuns.

Para resolver esse problema, a comunidade busca sempre soluções, como melhorias no software e aumento na escalabilidade, para facilitar o acesso à rede sem prejudicar a segurança.

Resumindo, os nós são a base da rede Bitcoin, desempenhando funções importantes na validação, verificação e distribuição de transações. Eles garantem a descentralização e a segurança do sistema, permitindo que os participantes operem de forma confiável sem depender de intermediários.

Particularmente, os nós completos têm um papel crucial na proteção da integridade do blockchain ou timechain, tornando a rede Bitcoin resistente a censura e manipulação.

Embora operar um nó possa exigir recursos técnicos, seu efeito na preservação da liberdade financeira e na confiança do sistema é inestimável. Assim, os nós continuam sendo elementos essenciais para o sucesso e a durabilidade do Bitcoin.

Muito obrigado por teres lido o texto até aqui, espero que esteja tudo bem contigo e um abraço enorme do teu madeirense bitcoiner maximalista favorito. Viva a liberdade!

This article was originally published on dev.to by satshacker.

Alright, you’ve built a useful and beautiful website, tool or app. However, monetization isn’t a priority and you’d rather keep the project free, ads-free and accessible?

Accepting donations would be an option, but how? A PayPal button? Stripe? Buymeacoffe? Patreon?

All of these services require a bank account and KYC verification, before you can send and receive donations – not very convenient.

If we only could send value over the internet, with just one click and without the need of a bank account…

Oh, hold on, that’s bitcoin. The decentralized protocol to send value across the globe. Money over TCP/IP.

In this article, we’ll learn how anyone can easily add a payment button or donation widget on a website or app.

Let’s get into it.

Introduction

Bitcoin is digital money that you can send and receive without the need for banks. While bitcoin is extremely secure, it’s not very fast. The maximum transactions per second (TPS) the network can handle is about 7. Obviously that’s not useful for daily payments or microtransactions.

If you’d like to dig deeper into how bitcoin works, a great read is “Mastering Bitcoin” by Andreas Antonopoulos.

Bitcoin vs Lightning

If you’d like to receive bitcoin donations “on-chain” all you need is a bitcoin wallet. You simply display your bitcoin address on your site and that’s it. You can receive donations.

It would look something like this; 1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa

Instead of showing the actual bitcoin address, you can also turn it into a QR code.

However, this is not a recommended solution. Using static on-chain addresses has two major downsides. It lowers privacy for you and your donnors and it’s a UTXO disaster because many small incoming transactions could beocme hard to consolidate in the future.

For donations and small transactions, the Lightning Network is the better option. Lightning allows for instant settlement with fees only a fraction of a cent.

Similar to bitcoin, you have the choice between non-custodial and custodial wallets. This means, either you have full control over your money or the wallet provider has.

Option 1: Lightning Address

With the lightning address feature, you an easily receive donations to an email like address.

It looks like this: yourname@wallet.com

Many wallets support lightning addresses and make it easy to create one. Then, you simple add the address to your donation page and you’re ready to receive tips.

You can also add a link link as in lightning:yourname@wallet.com and compatible lightning wallets and browser wallets will detect the address.

How to get a Lightning Address Fast

Option 2: Lightning Donation Widgets

If you like to take it a step further, you can also create a more enhanced donation checkout flow. Of course you could programm something yourself, there are many open source libraries you can build upon. If you want a simple plug-and-play solution, here are a couple of options:

Flash Releases Free Bitcoin Invoicing Tool with No Fees, KYC, or Custody

Flash, a Bitcoin payment platform, just announced it has launched Flash Invoicing, a completely free, non-custodial, and KYC-free Bitcoin invoicing tool. Designed for freelancers, the platform allows users to send professional invoices without platform fees, identity checks, or third party custody.

According to Deel, a crypto payments company for freelancers, Bitcoin is the most used cryptocurrency in the world for payments. Despite this growth, many freelancers continue to use basic methods such as pasting Bitcoin addresses into PDFs or emails. Some rely on custodial platforms that deduct fees or require identity verification, which can affect both earnings and data privacy.

“We’ve seen too many people paste BTC addresses into documents and call it invoicing,” said the CEO of Flash Pierre Corbin. “It’s messy. It’s risky. And it’s time for something better.” 

Flash Invoicing Features:

• 0% platform fees: no subscriptions or commission
• Non-custodial: Bitcoin goes straight to the user’s wallet
• No KYC: users maintain full privacy
• Professional output: branded PDFs and secure payment links
• Integrated dashboard: manage payments, clients, and revenue
• Works with Flash ecosystem: including Stores, Donations, Paywalls, and POS

Many Bitcoin invoicing tools charge a percentage per transaction or require a subscription. As a result, freelancers often lose part of their income simply to issue an invoice and receive payment. Flash is aiming to solve this issue.

“Freelancers work hard enough. The last thing they need is a platform skimming off their earnings,” said Corbin. “That’s why we dropped our fee from 1.5% to 0% — and launched the first invoicing tool that’s truly free, without compromising on privacy or control.”

Flash Invoicing allows users to accept Bitcoin payments without relinquishing control, privacy, or revenue. It is integrated with the broader Flash suite, enabling users to manage invoicing alongside features such as setting up stores, receiving donations, or gating premium content.

“As a freelancer myself, I love using the Flash invoicing feature,” stated a freelancer & Flash user. ”It keeps all my clients in one place, allows me to easily edit invoices and track payments. Much more professional than sending a lightning address in the footer of a PDF invoice.”

Bitcoin tem vindo a desempenhar um papel cada vez mais relevante em protestos e movimentos sociais em todo o mundo. Graças à sua natureza descentralizada, resistente à censura e independente do controlo governamental, Bitcoin tornou-se uma ferramenta valiosa para ativistas, organizações e cidadãos que lutam contra regimes opressivos ou sistemas financeiros restritivos.

Bitcoin como alternativa ao sistema financeiro tradicional

Nos últimos anos, governos e instituições bancárias têm utilizado restrições financeiras como uma forma de repressão política. Contas bancárias congeladas, doações bloqueadas e limitações a transações são algumas das estratégias utilizadas para enfraquecer movimentos sociais e protestos. Bitcoin oferece uma alternativa, permitindo que fundos sejam transferidos e armazenados sem a interferência de bancos ou governos.

Uma das principais vantagens de Bitcoin nestes contextos é a sua resistência à censura. Enquanto contas bancárias podem ser encerradas e serviços de pagamento centralizados podem ser pressionados a bloquear transações, Bitcoin funciona numa rede descentralizada, onde ninguém pode impedir que um utilizador envie ou receba fundos.

Exemplos do uso do Bitcoin em protestos

Hong Kong (2019-2020): Durante os protestos pró-democracia, ativistas enfrentaram restrições financeiras ao tentarem organizar manifestações e campanhas. Muitos recorreram a Bitcoin para evitar o rastreamento do governo chinês e garantir financiamento para as suas ações.

Canadá (2022): O movimento dos camionistas que protestavam contra restrições governamentais viu as suas contas bancárias congeladas. Como alternativa, doações em Bitcoin foram utilizadas para contornar a repressão financeira.

Bielorrússia (2020): Após as eleições presidenciais contestadas, manifestantes usaram Bitcoin para financiar atividades e ajudar aqueles que perderam os seus empregos devido à repressão estatal.

Nigéria (2020): Durante os protestos contra a brutalidade policial, conhecidos como #EndSARS, doações internacionais para os manifestantes foram bloqueadas. Bitcoin tornou-se um dos principais meios de financiamento do movimento.

Desafios do uso do Bitcoin em movimentos sociais

Educação e acessibilidade: Muitos ainda desconhecem como utilizar Bitcoin de forma segura e eficiente. A falta de conhecimento pode dificultar a sua adoção em larga escala.

Segurança digital: Movimentos sociais muitas vezes operam sob vigilância intensa. Se as medidas de segurança adequadas não forem seguidas, os fundos podem ser comprometidos.

Volatilidade: O preço de Bitcoin pode variar significativamente num curto período, o que pode afetar o valor das doações e dos fundos arrecadados.

Resumindo, o Bitcoin tem demonstrado ser uma ferramenta essencial para a resistência contra a censura financeira e a repressão governamental. Ao permitir que movimentos sociais e ativistas financiem as suas causas sem depender de intermediários, Bitcoin fortalece a luta pela liberdade e pela justiça. No entanto, a adoção eficaz da tecnologia exige conhecimento, segurança e adaptação às suas características únicas. À medida que mais pessoas aprendem a utilizar Bitcoin, o seu papel nos protestos e movimentos sociais continuará a crescer, reforçando a importância da soberania financeira na luta por direitos e liberdades.

Muito obrigado por teres lido o texto até aqui, espero que esteja tudo bem contigo e um abraço enorme do teu madeirense bitcoiner maximalista favorito. Viva a liberdade!

You've probably heard it before. A bitcoiner is asked about their sats and, with a sly smile, replies: “I lost it all in a boating accident.” But where did this phrase come from? Why do so many bitcoiners make this joke? And more importantly: what does it actually mean?

The Origin of the Meme The phrase "Lost all my Bitcoin in a boating accident" originally came from American forums among gun and precious metal enthusiasts—long before Bitcoin entered the mainstream. The original context went like this: someone would ask if you still owned your gold or firearm collection, and the sarcastic response would be, “Unfortunately, I lost everything in a boating accident.”

This excuse was used as a way to avoid declaring ownership of assets to the government or other authorities. After all, what can’t be proven to exist can’t be taxed, confiscated, or regulated. Over time, this logic found fertile ground among advocates of individual sovereignty—a group where bitcoiners naturally belong.

The Metaphor of Resistance When Bitcoin maximalists adopted the phrase, it came to represent more than just an excuse to dodge uncomfortable questions—it became a symbol of resistance against an increasingly invasive and coercive financial system. Saying you “lost your Bitcoin in a boating accident” is often a euphemism for:

“It’s none of your business how many sats I have.”

“I don’t recognize the authority of anyone trying to seize my digital wealth.”

“My assets are sovereign, self-custodied, and unreachable by traditional means.”

Bitcoin Is Freedom, Not Compliance The meme also touches on a core pillar of Bitcoin philosophy: self-custody and the right to financial privacy. In a world where governments freeze accounts, censor transactions, and print money at will, owning Bitcoin is a form of civil resistance. But for that to have real power, the individual must take responsibility—not just for custody, but for silence.

Saying you “lost your Bitcoin” is also a reminder: Don’t talk about your private keys. Don’t flaunt your sats. Don’t paint a target on your back.

A Meme With a Purpose At the end of the day, the “boating accident” is a joke with a very serious undertone. It reminds us that in a truly sovereign system, the ownership of digital assets is something intimate, personal—and, if needed, deniable. It’s a way to reaffirm that Bitcoin is not just a tool for investment, but a tool for freedom.

So next time someone asks where your bitcoins are, just smile and say:

“Unfortunately, I lost it all in a boating accident…”

And let them wonder.

Thank you very much for reading this far. I hope everything is well with you, and sending a big hug from your favorite Bitcoiner maximalist from Madeira. Long live freedom!

Milhões de pessoas em todo o mundo ainda não têm acesso a serviços bancários básicos, seja por falta de infraestrutura, requisitos burocráticos ou instabilidade económica nos seus países. Bitcoin surge como uma solução inovadora para este problema, permitindo que qualquer pessoa com acesso à internet tenha controlo sobre o seu dinheiro, sem depender de bancos ou governos. Ao oferecer um sistema financeiro aberto e acessível, Bitcoin torna-se uma ferramenta poderosa para a inclusão financeira global.

O problema da exclusão financeira

Em muitos países em desenvolvimento, grande parte da população não possui conta bancária. Isto pode acontecer por diversas razões, como:

Falta de acesso a bancos: Muitas comunidades, especialmente em áreas rurais, não têm instituições financeiras próximas.

Exigências burocráticas: Alguns bancos exigem documentação específica ou um histórico de crédito que muitas pessoas não conseguem fornecer.

Custos elevados: As taxas bancárias podem ser proibitivas para quem ganha pouco dinheiro.

Instabilidade económica e política: Em países com alta inflação ou governos instáveis, os bancos podem não ser uma opção segura para guardar dinheiro.

Estas dificuldades deixam milhões de pessoas à margem do sistema financeiro, impossibilitadas de poupar, investir ou realizar transações de forma eficiente.

Bitcoin como alternativa

Bitcoin resolve muitos dos problemas da exclusão financeira ao oferecer um sistema acessível e descentralizado. Com Bitcoin, qualquer pessoa com um telemóvel e acesso à internet pode armazenar e transferir dinheiro sem necessidade de um banco. Entre as principais vantagens estão:

Acessibilidade global: Bitcoin pode ser usado em qualquer lugar do mundo, independentemente da localização do utilizador.

Sem necessidade de intermediários: Diferente dos bancos, que impõem taxas e regras, Bitcoin permite transações diretas entre pessoas.

Baixo custo para transferências internacionais: Enviar dinheiro para outro país pode ser caro e demorado com os métodos tradicionais, enquanto Bitcoin oferece uma alternativa mais rápida e acessível.

Proteção contra a inflação: Em países com moedas instáveis, Bitcoin pode ser usado como reserva de valor, protegendo o poder de compra da população.

Casos de uso na inclusão financeira

Bitcoin já tem sido utilizado para promover a inclusão financeira em diversas partes do mundo. Alguns exemplos incluem:

África e América Latina: Em países como Nigéria, Venezuela e Argentina, onde a inflação é elevada e o acesso a dólares é limitado, muitas pessoas usam Bitcoin para preservar o seu dinheiro e realizar transações internacionais.

Remessas internacionais: Trabalhadores que enviam dinheiro para as suas famílias no estrangeiro evitam as elevadas taxas das empresas de transferências tradicionais ao utilizarem Bitcoin.

Microeconomia digital: Pequenos comerciantes e freelancers que não têm acesso a contas bancárias podem receber pagamentos em Bitcoin de forma direta e segura.

Desafios da inclusão financeira com Bitcoin

Apesar das suas vantagens, a adoção de Bitcoin como ferramenta de inclusão financeira ainda enfrenta alguns desafios, tais como:

Acesso à internet: Muitas regiões pobres ainda não têm uma infraestrutura digital adequada.

Educação financeira: Para que mais pessoas utilizem Bitcoin, é necessário maior conhecimento sobre a tecnologia e as melhores práticas de segurança.

Volatilidade do preço: As oscilações de valor podem dificultar o uso de Bitcoin no dia a dia, especialmente em países onde as pessoas vivem com rendimentos instáveis.

Resumindo, o Bitcoin oferece uma solução viável para milhões de pessoas excluídas do sistema financeiro tradicional. Ao proporcionar acesso global, transações baratas e segurança contra a inflação, torna-se um instrumento poderoso para promover a inclusão financeira. No entanto, para que o seu potencial seja totalmente aproveitado, é essencial investir na educação digital e expandir a infraestrutura tecnológica, permitindo que mais pessoas tenham autonomia financeira através de Bitcoin.

Muito obrigado por teres lido o texto até aqui, espero que esteja tudo bem contigo e um abraço enorme do teu madeirense bitcoiner maximalista favorito. Viva a liberdade!

Desde a sua criação, Bitcoin tem sido associado à ideia de liberdade financeira e individual. Diferente do dinheiro tradicional, controlado por governos e bancos centrais, Bitcoin permite que qualquer pessoa no mundo transacione e armazene valor sem depender de intermediários. Essa característica torna-se especialmente relevante em contextos de instabilidade económica, censura financeira e falta de acesso ao sistema bancário.

Bitcoin como ferramenta de autonomia financeira

A principal promessa de Bitcoin é devolver às pessoas o controlo sobre o seu próprio dinheiro. No sistema financeiro tradicional, os bancos e governos têm o poder de congelar contas, restringir transações e desvalorizar moedas através da impressão excessiva de dinheiro. Com Bitcoin, cada utilizador tem total posse dos seus fundos, desde que armazene as suas chaves privadas de forma segura. Isso significa que ninguém pode confiscar ou bloquear o acesso ao seu dinheiro.

Além disso, Bitcoin permite transações internacionais rápidas e baratas, sem depender de bancos ou plataformas de pagamento centralizadas. Em países onde as transferências internacionais são burocráticas e caras, Bitcoin representa uma alternativa eficiente e acessível.

Proteção contra a censura e o controlo estatal

Governos e instituições financeiras podem restringir o acesso ao dinheiro por motivos políticos ou económicos. Em regimes autoritários, dissidentes e jornalistas frequentemente enfrentam bloqueios financeiros como forma de repressão. Bitcoin oferece uma solução para esse problema, pois a sua rede descentralizada impede que qualquer entidade tenha controlo total sobre as transações.

Isto já foi demonstrado em diversos casos ao redor do mundo. Em momentos de crise, quando governos impõem restrições a saques bancários ou impõem limites às remessas de dinheiro, Bitcoin tem sido usado para contornar essas barreiras e garantir que as pessoas possam manter a sua liberdade financeira.

Desafios e responsabilidades da liberdade financeira

Embora Bitcoin ofereça mais liberdade individual, também exige maior responsabilidade por parte do utilizador. Diferente de uma conta bancária, onde um cliente pode recuperar o acesso à sua conta com um simples pedido, em Bitcoin a posse das chaves privadas é essencial. Se um utilizador perde as suas chaves, perde o acesso aos seus fundos para sempre.

Além disso, a volatilidade do preço de Bitcoin pode representar um desafio para quem pretende utilizá-lo como reserva de valor no curto prazo. No entanto, essa característica é compensada pelo seu modelo deflacionário, que protege a poupança a longo prazo contra a desvalorização causada pela inflação das moedas fiduciárias.

Resumindo, o Bitcoin representa uma revolução na forma como as pessoas gerem e protegem o seu dinheiro. Ao permitir transações livres de intermediários e resistir à censura financeira, Bitcoin fortalece a liberdade individual e oferece uma alternativa viável a sistemas financeiros centralizados e controlados por governos. No entanto, essa liberdade vem acompanhada da necessidade de maior responsabilidade, uma vez que cada utilizador é o único responsável pela segurança dos seus fundos. Para aqueles que valorizam a soberania financeira, Bitcoin é uma ferramenta poderosa que pode redefinir o conceito de dinheiro e autonomia pessoal no mundo moderno.

• This version introduces the Soroban P2P network, enabling Dojo to relay transactions to the Bitcoin network and share others' transactions to break the heuristic linking relaying nodes to transaction creators.

• Additionally, Dojo admins can now manage API keys in DMT with labels, status, and expiration, ideal for community Dojo providers like Dojobay. New API endpoints, including "/services" exposing Explorer, Soroban, and Indexer, have been added to aid wallet developers.
• Other maintenance updates include Bitcoin Core, Tor, Fulcrum, Node.js, plus an updated ban-knots script to disconnect inbound Knots nodes.

"I want to thank all the contributors. This again shows the power of true Free Software. I also want to thank everyone who donated to help Dojo development going. I truly appreciate it," said Still Dojo Coder.

What's new

• Soroban P2P network. For MyDojo (Docker setup) users, Soroban will be automatically installed as part of their Dojo. This integration allows Dojo to utilize the Soroban P2P network for various upcoming features and applications.
• PandoTx. PandoTx serves as a transaction transport layer. When your wallet sends a transaction to Dojo, it is relayed to a random Soroban node, which then forwards it to the Bitcoin network. It also enables your Soroban node to receive and relay transactions from others to the Bitcoin network and is designed to disrupt the assumption that a node relaying a transaction is closely linked to the person who initiated it.
  • Pushing transactions through Soroban can be deactivated by setting NODE_PANDOTX_PUSH=off in docker-node.conf.
  • Processing incoming transactions from Soroban network can be deactivated by setting NODE_PANDOTX_PROCESS=off in docker-node.conf.
• API key management has been introduced to address the growing number of people offering their Dojos to the community. Dojo admins can now access a new API management tab in their DMT, where they can create unlimited API keys, assign labels for easy identification, and set expiration dates for each key. This allows admins to avoid sharing their main API key and instead distribute specific keys to selected parties.
• New API endpoints. Several new API endpoints have been added to help API consumers develop features on Dojo more efficiently:
  • New:
    • /latest-block - returns data about latest block
    • /txout/:txid/:index - returns unspent output data
    • /support/services - returns info about services that Dojo exposes
  • Updated:
    • /tx/:txid - endpoint has been updated to return raw transaction with parameter ?rawHex=1
  • The new /support/services endpoint replaces the deprecated explorer field in the Dojo pairing payload. Although still present, API consumers should use this endpoint for explorer and other pairing data.

Other changes

• Updated ban script to disconnect inbound Knots nodes.
• Updated Fulcrum to v1.12.0.
• Regenerate Fulcrum certificate if expired.
• Check if transaction already exists in pushTx.
• Bump BTC-RPC Explorer.
• Bump Tor to v0.4.8.16, bump Snowflake.
• Updated Bitcoin Core to v29.0.
• Removed unnecessary middleware.
• Fixed DB update mechanism, added api_keys table.
• Add an option to use blocksdir config for bitcoin blocks directory.
• Removed deprecated configuration.
• Updated Node.js dependencies.
• Reconfigured container dependencies.
• Fix Snowflake git URL.
• Fix log path for testnet4.
• Use prebuilt addrindexrs binaries.
• Add instructions to migrate blockchain/fulcrum.
• Added pull policies.

A história do Bitcoin é pontuada por marcos simbólicos que representam não apenas a evolução técnica da moeda digital, mas também sua trajetória rumo à legitimidade econômica e política. Neste artigo, revisitamos alguns dos momentos mais emblemáticos que marcaram a adoção do Bitcoin, desde seu uso inicial em uma simples transação até o seu reconhecimento como moeda oficial por nações soberanas.

A pizza mais cara da história

Em 22 de maio de 2010, Laszlo Hanyecz fez história ao pagar 10.000 BTC por duas pizzas. Na época, essa quantia equivalia a cerca de 40 dólares. Hoje, essas mesmas moedas valeriam centenas de milhões de dólares, tornando essa a refeição mais cara já registrada. Mais do que uma curiosidade, essa transação marcou a primeira vez em que o Bitcoin foi usado em uma troca comercial real, comprovando seu potencial como meio de pagamento.

Silk Road e o lado obscuro da adoção inicial

Ainda que controverso, o uso do Bitcoin no marketplace Silk Road mostrou ao mundo que a moeda digital era funcional como meio de troca em larga escala. A plataforma operou entre 2011 e 2013 e foi um catalisador para o desenvolvimento de infraestrutura em torno do BTC, apesar dos impactos negativos na imagem da criptomoeda.

Mt. Gox e a primeira grande crise

Em 2014, a corretora Mt. Gox, responsável por cerca de 70% das transações de Bitcoin no mundo, declarou falência após perder cerca de 850 mil BTC. O escândalo abalou a confiança no ecossistema, mas também deu início a um movimento de amadurecimento: a busca por melhores práticas de segurança, regulação e profissionalização do setor.

El Salvador e o reconhecimento oficial

Em setembro de 2021, El Salvador tornou-se o primeiro país a reconhecer o Bitcoin como moeda de curso legal. A medida, defendida pelo presidente Nayib Bukele, foi recebida com entusiasmo por entusiastas e com ceticismo por instituições financeiras internacionais. O experimento salvadorenho colocou o Bitcoin no centro do debate geopolítico e abriu precedentes para outras nações considerarem o mesmo caminho.

Resumindo, cada um desses momentos representa uma etapa distinta na evolução do Bitcoin: da experimentação à adoção institucional. Ao revisitarmos esses casos emblemáticos, conseguimos entender não apenas como o Bitcoin evoluiu tecnicamente, mas também como sua narrativa se consolidou como parte da história financeira contemporânea. Se a compra da pizza simbolizou o nascimento prático do BTC, o reconhecimento oficial por nações inteiras sugere um futuro em que a moeda digital pode ser protagonista em novas formas de organização econômica global.

People forget Bear Stearns failed March 2008 - months of denial followed before the public realized how bad the situation was under the surface.

Similar happening now but much larger scale. They did not fix fundamental issues after 2008 - everything is more fragile.

The Fed preemptively bailed out every bank with their BTFP program and First Republic Bank still failed. The second largest bank failure in history.

There will be more failures. There will be more bailouts. Depositors will be "protected" by socializing losses across everyone.

Our President and mainstream financial pundits are currently pretending the banking crisis is over while most banks remain insolvent. There are going to be many more bank failures as this ponzi system unravels.

Unlike 2008, we have the ability to opt out of these broken and corrupt institutions by using bitcoin. Bitcoin held in self custody is unique in its lack of counterparty risk - you do not have to trust a bank or other centralized entity to hold it for you. Bitcoin is also incredibly difficult to change by design since it is not controlled by an individual, company, or government - the supply of dollars will inevitably be inflated to bailout these failing banks but bitcoin supply will remain unchanged. I do not need to convince you that bitcoin provides value - these next few years will convince millions.

Desde a sua criação, Bitcoin tem sido visto tanto como uma inovação financeira quanto como uma ameaça ao controlo governamental sobre a economia. Como uma moeda descentralizada, Bitcoin opera fora do sistema financeiro tradicional, desafiando a autoridade dos bancos centrais e dos governos que regulam a emissão e circulação do dinheiro. Essa característica tem levado a diversos conflitos entre governos e a crescente adoção de Bitcoin por indivíduos e empresas.

Razões para a oposição governamental

Perda de controlo monetário: Os governos controlam a economia através da emissão de moeda fiduciária e da definição de políticas monetárias. Como Bitcoin tem uma oferta fixa e não pode ser manipulado, isso reduz a influência governamental sobre a economia.

Dificuldade na tributação e fiscalização: A natureza descentralizada de Bitcoin dificulta a cobrança de impostos e o rastreamento de transações, tornando mais difícil para os governos garantir a conformidade fiscal.

Concorrência com moedas digitais estatais (CBDCs): Muitos países estão a desenvolver moedas digitais de banco central (CBDCs), que oferecem maior controlo sobre as transações financeiras. Bitcoin representa uma alternativa descentralizada, o que pode ameaçar a adoção dessas moedas estatais.

Preocupações com crimes financeiros: Alguns governos argumentam que Bitcoin pode ser usado para lavagem de dinheiro e financiamento ilícito, apesar de ser mais rastreável do que o dinheiro físico devido à transparência da blockchain ou timechain.

Exemplos de conflitos entre governos e Bitcoin

El Salvador: Foi o primeiro país a tornar Bitcoin moeda legal em 2021. Essa decisão gerou reações negativas de instituições financeiras internacionais, como o FMI, que alertou para riscos económicos e tentou pressionar o país a reverter a sua decisão.

China: Em 2021, a China proibiu a mineração e o uso de Bitcoin, citando preocupações ambientais e riscos financeiros. Apesar da proibição, muitos utilizadores chineses continuam a usar Bitcoin de forma descentralizada.

Estados Unidos: Embora Bitcoin seja legal nos EUA, o governo tem aumentado a regulamentação sobre exchanges e mineradores, tentando exercer maior controlo sobre a rede.

União Europeia: A UE tem imposto regulamentos rigorosos sobre Bitcoin, como exigências de identificação para transações, mas não proibiu a sua utilização.

O futuro da adoção do Bitcoin

Apesar da resistência de alguns governos, Bitcoin continua a ser adotado por indivíduos e empresas como uma alternativa financeira segura. Em países com economias instáveis, Bitcoin tem sido uma ferramenta essencial para proteger a riqueza contra a inflação e restrições bancárias.

A tentativa de controlo governamental pode dificultar a adoção de Bitcoin em algumas regiões, mas não impedirá o seu crescimento global. Como uma rede descentralizada, Bitcoin não pode ser banido completamente, e a sua utilidade como reserva de valor e meio de troca continuará a atrair utilizadores em todo o mundo.

Resumindo, os conflitos entre governos e a adoção de Bitcoin refletem o choque entre um sistema financeiro centralizado e uma tecnologia descentralizada que devolve o controlo do dinheiro aos indivíduos. Embora alguns governos tentem restringir o seu uso, Bitcoin continua a crescer e a provar a sua resistência, tornando-se cada vez mais uma opção viável para aqueles que procuram liberdade financeira.

Muito obrigado por teres lido o texto até aqui, espero que esteja tudo bem contigo e um abraço enorme do teu madeirense bitcoiner maximalista favorito. Viva a liberdade!

Os princípios básicos da criptografia.

Quando Júlio César enviou mensagens aos seus generais, ele não confiou nos seus mensageiros. Então ele substituiu cada A em suas mensagens por um D, cada B por um E, e assim por diante através do alfabeto. Somente alguém que conhecesse a regra “shift by 3” poderia decifrar suas mensagens. E assim começamos.

Criptografia e descriptografia.

Os dados que podem ser lidos e compreendidos sem quaisquer medidas especiais são chamados de texto simples ou texto não criptografado. O método de disfarçar o texto simples de forma a ocultar sua substância é chamado de criptografia. Criptografar texto simples resulta em um jargão ilegível chamado texto cifrado. Você usa criptografia para garantir que as informações sejam ocultadas de qualquer pessoa a quem não se destinam, mesmo daqueles que podem ver os dados criptografados. O processo de reverter o texto cifrado ao texto simples original é chamado de descriptografia . A Figura 1-1 ilustra esse processo.

https://image.nostr.build/0e2fcb71ed86a6083e083abbb683f8c103f44a6c6db1aeb2df10ae51ec97ebe5.jpg

Figura 1-1. Criptografia e descriptografia

O que é criptografia?

Criptografia é a ciência que usa a matemática para criptografar e descriptografar dados. A criptografia permite armazenar informações confidenciais ou transmiti-las através de redes inseguras (como a Internet) para que não possam ser lidas por ninguém, exceto pelo destinatário pretendido. Embora a criptografia seja a ciência que protege os dados, a criptoanálise é a ciência que analisa e quebra a comunicação segura. A criptoanálise clássica envolve uma combinação interessante de raciocínio analítico, aplicação de ferramentas matemáticas, descoberta de padrões, paciência, determinação e sorte. Os criptoanalistas também são chamados de atacantes. A criptologia abrange tanto a criptografia quanto a criptoanálise.

Criptografia forte.

"Existem dois tipos de criptografia neste mundo: a criptografia que impedirá a sua irmã mais nova de ler os seus arquivos, e a criptografia que impedirá os principais governos de lerem os seus arquivos. Este livro é sobre o último." --Bruce Schneier, Criptografia Aplicada: Protocolos, Algoritmos e Código Fonte em C. PGP também trata deste último tipo de criptografia. A criptografia pode ser forte ou fraca, conforme explicado acima. A força criptográfica é medida no tempo e nos recursos necessários para recuperar o texto simples. O resultado de uma criptografia forte é um texto cifrado que é muito difícil de decifrar sem a posse da ferramenta de decodificação apropriada. Quão díficil? Dado todo o poder computacional e o tempo disponível de hoje – mesmo um bilhão de computadores fazendo um bilhão de verificações por segundo – não é possível decifrar o resultado de uma criptografia forte antes do fim do universo. Alguém poderia pensar, então, que uma criptografia forte resistiria muito bem até mesmo contra um criptoanalista extremamente determinado. Quem pode realmente dizer? Ninguém provou que a criptografia mais forte disponível hoje resistirá ao poder computacional de amanhã. No entanto, a criptografia forte empregada pelo PGP é a melhor disponível atualmente.

Contudo, a vigilância e o conservadorismo irão protegê-lo melhor do que as alegações de impenetrabilidade.

Como funciona a criptografia?

Um algoritmo criptográfico, ou cifra, é uma função matemática usada no processo de criptografia e descriptografia. Um algoritmo criptográfico funciona em combinação com uma chave – uma palavra, número ou frase – para criptografar o texto simples. O mesmo texto simples é criptografado em texto cifrado diferente com chaves diferentes. A segurança dos dados criptografados depende inteiramente de duas coisas: a força do algoritmo criptográfico e o sigilo da chave. Um algoritmo criptográfico, mais todas as chaves possíveis e todos os protocolos que o fazem funcionar constituem um criptossistema. PGP é um criptossistema.

Criptografia convencional.

Na criptografia convencional, também chamada de criptografia de chave secreta ou de chave simétrica , uma chave é usada tanto para criptografia quanto para descriptografia. O Data Encryption Standard (DES) é um exemplo de criptossistema convencional amplamente empregado pelo Governo Federal. A Figura 1-2 é uma ilustração do processo de criptografia convencional. https://image.nostr.build/328b73ebaff84c949df2560bbbcec4bc3b5e3a5163d5fbb2ec7c7c60488f894c.jpg

Figura 1-2. Criptografia convencional

Cifra de César.

Um exemplo extremamente simples de criptografia convencional é uma cifra de substituição. Uma cifra de substituição substitui uma informação por outra. Isso é feito com mais frequência compensando as letras do alfabeto. Dois exemplos são o Anel Decodificador Secreto do Capitão Meia-Noite, que você pode ter possuído quando era criança, e a cifra de Júlio César. Em ambos os casos, o algoritmo serve para compensar o alfabeto e a chave é o número de caracteres para compensá-lo. Por exemplo, se codificarmos a palavra "SEGREDO" usando o valor chave de César de 3, deslocaremos o alfabeto para que a terceira letra abaixo (D) comece o alfabeto. Então começando com A B C D E F G H I J K L M N O P Q R S T U V W X Y Z e deslizando tudo para cima em 3, você obtém DEFGHIJKLMNOPQRSTUVWXYZABC onde D=A, E=B, F=C e assim por diante. Usando este esquema, o texto simples, "SECRET" é criptografado como "VHFUHW". Para permitir que outra pessoa leia o texto cifrado, você diz a ela que a chave é 3. Obviamente, esta é uma criptografia extremamente fraca para os padrões atuais, mas, ei, funcionou para César e ilustra como funciona a criptografia convencional.

Gerenciamento de chaves e criptografia convencional.

A criptografia convencional tem benefícios. É muito rápido. É especialmente útil para criptografar dados que não vão a lugar nenhum. No entanto, a criptografia convencional por si só como meio de transmissão segura de dados pode ser bastante cara, simplesmente devido à dificuldade de distribuição segura de chaves. Lembre-se de um personagem do seu filme de espionagem favorito: a pessoa com uma pasta trancada e algemada ao pulso. Afinal, o que há na pasta? Provavelmente não é o código de lançamento de mísseis/fórmula de biotoxina/plano de invasão em si. É a chave que irá descriptografar os dados secretos. Para que um remetente e um destinatário se comuniquem com segurança usando criptografia convencional, eles devem chegar a um acordo sobre uma chave e mantê-la secreta entre si. Se estiverem em locais físicos diferentes, devem confiar em um mensageiro, no Bat Phone ou em algum outro meio de comunicação seguro para evitar a divulgação da chave secreta durante a transmissão. Qualquer pessoa que ouvir ou interceptar a chave em trânsito poderá posteriormente ler, modificar e falsificar todas as informações criptografadas ou autenticadas com essa chave. Do DES ao Anel Decodificador Secreto do Capitão Midnight, o problema persistente com a criptografia convencional é a distribuição de chaves: como você leva a chave ao destinatário sem que alguém a intercepte?

Criptografia de chave pública.

Os problemas de distribuição de chaves são resolvidos pela criptografia de chave pública, cujo conceito foi introduzido por Whitfield Diffie e Martin Hellman em 1975. (Há agora evidências de que o Serviço Secreto Britânico a inventou alguns anos antes de Diffie e Hellman, mas a manteve um segredo militar - e não fez nada com isso.

[JH Ellis: The Possibility of Secure Non-Secret Digital Encryption, CESG Report, January 1970]) A criptografia de chave pública é um esquema assimétrico que usa um par de chaves para criptografia: uma chave pública, que criptografa os dados, e uma chave privada ou secreta correspondente para descriptografia. Você publica sua chave pública para o mundo enquanto mantém sua chave privada em segredo. Qualquer pessoa com uma cópia da sua chave pública pode criptografar informações que somente você pode ler. Até mesmo pessoas que você nunca conheceu. É computacionalmente inviável deduzir a chave privada da chave pública. Qualquer pessoa que possua uma chave pública pode criptografar informações, mas não pode descriptografá-las. Somente a pessoa que possui a chave privada correspondente pode descriptografar as informações. https://image.nostr.build/fdb71ae7a4450a523456827bdd509b31f0250f63152cc6f4ba78df290887318b.jpg

Figura 1-3. Criptografia de chave pública O principal benefício da criptografia de chave pública é que ela permite que pessoas que não possuem nenhum acordo de segurança pré-existente troquem mensagens com segurança. A necessidade de remetente e destinatário compartilharem chaves secretas através de algum canal seguro é eliminada; todas as comunicações envolvem apenas chaves públicas e nenhuma chave privada é transmitida ou compartilhada. Alguns exemplos de criptossistemas de chave pública são Elgamal (nomeado em homenagem a seu inventor, Taher Elgamal), RSA (nomeado em homenagem a seus inventores, Ron Rivest, Adi Shamir e Leonard Adleman), Diffie-Hellman (nomeado, você adivinhou, em homenagem a seus inventores). ) e DSA, o algoritmo de assinatura digital (inventado por David Kravitz). Como a criptografia convencional já foi o único meio disponível para transmitir informações secretas, o custo dos canais seguros e da distribuição de chaves relegou a sua utilização apenas àqueles que podiam pagar, como governos e grandes bancos (ou crianças pequenas com anéis descodificadores secretos). A criptografia de chave pública é a revolução tecnológica que fornece criptografia forte para as massas adultas. Lembra do mensageiro com a pasta trancada e algemada ao pulso? A criptografia de chave pública o tira do mercado (provavelmente para seu alívio).

Como funciona o PGP.

O PGP combina alguns dos melhores recursos da criptografia convencional e de chave pública. PGP é um criptossistema híbrido. Quando um usuário criptografa texto simples com PGP, o PGP primeiro compacta o texto simples. A compactação de dados economiza tempo de transmissão do modem e espaço em disco e, mais importante ainda, fortalece a segurança criptográfica. A maioria das técnicas de criptoanálise explora padrões encontrados no texto simples para quebrar a cifra. A compressão reduz esses padrões no texto simples, aumentando assim enormemente a resistência à criptoanálise. (Arquivos que são muito curtos para compactar ou que não são compactados bem não são compactados.) O PGP então cria uma chave de sessão, que é uma chave secreta única. Esta chave é um número aleatório gerado a partir dos movimentos aleatórios do mouse e das teclas digitadas. Esta chave de sessão funciona com um algoritmo de criptografia convencional rápido e muito seguro para criptografar o texto simples; o resultado é texto cifrado. Depois que os dados são criptografados, a chave da sessão é criptografada na chave pública do destinatário. Essa chave de sessão criptografada com chave pública é transmitida junto com o texto cifrado ao destinatário.

Figura 1-4. Como funciona a criptografia PGP A descriptografia funciona ao contrário. A cópia do PGP do destinatário usa sua chave privada para recuperar a chave de sessão temporária, que o PGP usa para descriptografar o texto cifrado criptografado convencionalmente.

Figura 1-5. Como funciona a descriptografia PGP A combinação dos dois métodos de criptografia combina a conveniência da criptografia de chave pública com a velocidade da criptografia convencional. A criptografia convencional é cerca de 1.000 vezes mais rápida que a criptografia de chave pública. A criptografia de chave pública, por sua vez, fornece uma solução para

problemas de distribuição de chaves e transmissão de dados. Usados ​​em conjunto, o desempenho e a distribuição de chaves são melhorados sem qualquer sacrifício na segurança.

Chaves.

Uma chave é um valor que funciona com um algoritmo criptográfico para produzir um texto cifrado específico. As chaves são basicamente números muito, muito, muito grandes. O tamanho da chave é medido em bits; o número que representa uma chave de 1024 bits é enorme. Na criptografia de chave pública, quanto maior a chave, mais seguro é o texto cifrado. No entanto, o tamanho da chave pública e o tamanho da chave secreta da criptografia convencional não têm nenhuma relação. Uma chave convencional de 80 bits tem a força equivalente a uma chave pública de 1.024 bits. Uma chave convencional de 128 bits é equivalente a uma chave pública de 3.000 bits. Novamente, quanto maior a chave, mais segura, mas os algoritmos usados ​​para cada tipo de criptografia são muito diferentes e, portanto, a comparação é como a de maçãs com laranjas. Embora as chaves pública e privada estejam matematicamente relacionadas, é muito difícil derivar a chave privada dada apenas a chave pública; no entanto, derivar a chave privada é sempre possível, desde que haja tempo e capacidade computacional suficientes. Isto torna muito importante escolher chaves do tamanho certo; grande o suficiente para ser seguro, mas pequeno o suficiente para ser aplicado rapidamente. Além disso, você precisa considerar quem pode estar tentando ler seus arquivos, quão determinados eles estão, quanto tempo têm e quais podem ser seus recursos. Chaves maiores serão criptograficamente seguras por um longo período de tempo. Se o que você deseja criptografar precisar ficar oculto por muitos anos, você pode usar uma chave muito grande. Claro, quem sabe quanto tempo levará para determinar sua chave usando os computadores mais rápidos e eficientes de amanhã? Houve um tempo em que uma chave simétrica de 56 bits era considerada extremamente segura. As chaves são armazenadas de forma criptografada. O PGP armazena as chaves em dois arquivos no seu disco rígido; um para chaves públicas e outro para chaves privadas. Esses arquivos são chamados de chaveiros. Ao usar o PGP, você normalmente adicionará as chaves públicas dos seus destinatários ao seu chaveiro público. Suas chaves privadas são armazenadas em seu chaveiro privado. Se você perder seu chaveiro privado, não será possível descriptografar nenhuma informação criptografada nas chaves desse anel.

Assinaturas digitais.

Um grande benefício da criptografia de chave pública é que ela fornece um método para empregar assinaturas digitais. As assinaturas digitais permitem ao destinatário da informação verificar a autenticidade da origem da informação e também verificar se a informação está intacta. Assim, as assinaturas digitais de chave pública fornecem autenticação e integridade de dados. A assinatura digital também proporciona o não repúdio, o que significa que evita que o remetente alegue que não enviou realmente as informações. Esses recursos são tão fundamentais para a criptografia quanto a privacidade, se não mais. Uma assinatura digital tem a mesma finalidade de uma assinatura manuscrita. No entanto, uma assinatura manuscrita é fácil de falsificar. Uma assinatura digital é superior a uma assinatura manuscrita porque é quase impossível de ser falsificada, além de atestar o conteúdo da informação, bem como a identidade do signatário.

Algumas pessoas tendem a usar mais assinaturas do que criptografia. Por exemplo, você pode não se importar se alguém souber que você acabou de depositar US$ 1.000 em sua conta, mas quer ter certeza de que foi o caixa do banco com quem você estava lidando. A maneira básica pela qual as assinaturas digitais são criadas é ilustrada na Figura 1-6 . Em vez de criptografar informações usando a chave pública de outra pessoa, você as criptografa com sua chave privada. Se as informações puderem ser descriptografadas com sua chave pública, elas deverão ter se originado em você.

Figura 1-6. Assinaturas digitais simples

Funções hash.

O sistema descrito acima apresenta alguns problemas. É lento e produz um enorme volume de dados – pelo menos o dobro do tamanho da informação original. Uma melhoria no esquema acima é a adição de uma função hash unidirecional no processo. Uma função hash unidirecional recebe uma entrada de comprimento variável – neste caso, uma mensagem de qualquer comprimento, até mesmo milhares ou milhões de bits – e produz uma saída de comprimento fixo; digamos, 160 bits. A função hash garante que, se a informação for alterada de alguma forma – mesmo que por apenas um bit – seja produzido um valor de saída totalmente diferente. O PGP usa uma função hash criptograficamente forte no texto simples que o usuário está assinando. Isso gera um item de dados de comprimento fixo conhecido como resumo da mensagem. (Novamente, qualquer alteração nas informações resulta em um resumo totalmente diferente.) Então o PGP usa o resumo e a chave privada para criar a “assinatura”. O PGP transmite a assinatura e o texto simples juntos. Ao receber a mensagem, o destinatário utiliza o PGP para recalcular o resumo, verificando assim a assinatura. O PGP pode criptografar o texto simples ou não; assinar texto simples é útil se alguns dos destinatários não estiverem interessados ​​ou não forem capazes de verificar a assinatura. Desde que uma função hash segura seja usada, não há como retirar a assinatura de alguém de um documento e anexá-la a outro, ou alterar uma mensagem assinada de qualquer forma. A menor alteração em um documento assinado causará falha no processo de verificação da assinatura digital.

Figura 1-7. Assinaturas digitais seguras As assinaturas digitais desempenham um papel importante na autenticação e validação de chaves de outros usuários PGP.

Certificados digitais.

Um problema com os criptosistemas de chave pública é que os usuários devem estar constantemente vigilantes para garantir que estão criptografando com a chave da pessoa correta. Num ambiente onde é seguro trocar chaves livremente através de servidores públicos, os ataques man-in-the-middle são uma ameaça potencial. Neste tipo de ataque, alguém publica uma chave falsa com o nome e ID de usuário do destinatário pretendido. Os dados criptografados – e interceptados por – o verdadeiro proprietário desta chave falsa estão agora em mãos erradas. Em um ambiente de chave pública, é vital que você tenha certeza de que a chave pública para a qual você está criptografando os dados é de fato a chave pública do destinatário pretendido e não uma falsificação. Você pode simplesmente criptografar apenas as chaves que foram entregues fisicamente a você. Mas suponha que você precise trocar informações com pessoas que nunca conheceu; como você pode saber se tem a chave correta? Os certificados digitais, ou certs, simplificam a tarefa de estabelecer se uma chave pública realmente pertence ao suposto proprietário. Um certificado é uma forma de credencial. Exemplos podem ser sua carteira de motorista, seu cartão de previdência social ou sua certidão de nascimento. Cada um deles contém algumas informações que identificam você e alguma autorização informando que outra pessoa confirmou sua identidade. Alguns certificados, como o seu passaporte, são uma confirmação importante o suficiente da sua identidade para que você não queira perdê-los, para que ninguém os use para se passar por você.

Um certificado digital são dados que funcionam como um certificado físico. Um certificado digital é uma informação incluída na chave pública de uma pessoa que ajuda outras pessoas a verificar se uma chave é genuína ou válida. Os certificados digitais são usados ​​para impedir tentativas de substituir a chave de uma pessoa por outra.

Um certificado digital consiste em três coisas:

● Uma chave pública.

● Informações do certificado. (Informações de "identidade" sobre o usuário, como nome, ID do usuário e assim por diante.) ● Uma ou mais assinaturas digitais.

O objetivo da assinatura digital em um certificado é afirmar que as informações do certificado foram atestadas por alguma outra pessoa ou entidade. A assinatura digital não atesta a autenticidade do certificado como um todo; ele atesta apenas que as informações de identidade assinadas acompanham ou estão vinculadas à chave pública. Assim, um certificado é basicamente uma chave pública com uma ou duas formas de identificação anexadas, além de um forte selo de aprovação de algum outro indivíduo confiável. Figura 1-8. Anatomia de um certificado PGP

Distribuição de certificados.

Os certificados são utilizados quando é necessário trocar chaves públicas com outra pessoa. Para pequenos grupos de pessoas que desejam se comunicar com segurança, é fácil trocar manualmente disquetes ou e-mails contendo a chave pública de cada proprietário. Esta é a distribuição manual de chave pública e é prática apenas até certo ponto. Além desse ponto, é necessário implementar sistemas que possam fornecer os mecanismos necessários de segurança, armazenamento e troca para que colegas de trabalho, parceiros de negócios ou estranhos possam se comunicar, se necessário. Eles podem vir na forma de repositórios somente de armazenamento, chamados Servidores de Certificados, ou sistemas mais estruturados que fornecem recursos adicionais de gerenciamento de chaves e são chamados de Infraestruturas de Chave Pública (PKIs).

Servidores de certificados.

Um servidor de certificados, também chamado de servidor certificado ou servidor de chaves, é um banco de dados que permite aos usuários enviar e recuperar certificados digitais. Um servidor certificado geralmente fornece alguns recursos administrativos que permitem que uma empresa mantenha suas políticas de segurança – por exemplo, permitindo que apenas as chaves que atendam a determinados requisitos sejam armazenadas.

Infraestruturas de Chave Pública.

Uma PKI contém os recursos de armazenamento de certificados de um servidor de certificados, mas também fornece recursos de gerenciamento de certificados (a capacidade de emitir, revogar, armazenar, recuperar e confiar em certificados). A principal característica de uma PKI é a introdução do que é conhecido como Autoridade Certificadora,ou CA, que é uma entidade humana — uma pessoa, grupo, departamento, empresa ou outra associação — que uma organização autorizou a emitir certificados para seus usuários de computador. (A função de uma CA é análoga à do Passport Office do governo de um país.) Uma CA cria certificados e os assina digitalmente usando a chave privada da CA. Devido ao seu papel na criação de certificados, a CA é o componente central de uma PKI. Usando a chave pública da CA, qualquer pessoa que queira verificar a autenticidade de um certificado verifica a assinatura digital da CA emissora e, portanto, a integridade do conteúdo do certificado (mais importante ainda, a chave pública e a identidade do titular do certificado).

Formatos de certificado.

Um certificado digital é basicamente uma coleção de informações de identificação vinculadas a uma chave pública e assinadas por um terceiro confiável para provar sua autenticidade. Um certificado digital pode ter vários formatos diferentes.

O PGP reconhece dois formatos de certificado diferentes:

● Certificados PGP ● Certificados X.509 Formato do certificado PGP. Um certificado PGP inclui (mas não está limitado a) as seguintes informações: ● O número da versão do PGP — identifica qual versão do PGP foi usada para criar a chave associada ao certificado. A chave pública do titular do certificado — a parte pública do seu par de chaves, juntamente com o algoritmo da chave: RSA, DH (Diffie-Hellman) ou DSA (Algoritmo de Assinatura Digital).

● As informações do detentor do certificado — consistem em informações de “identidade” sobre o usuário, como seu nome, ID de usuário, fotografia e assim por diante. ● A assinatura digital do proprietário do certificado — também chamada de autoassinatura, é a assinatura que utiliza a chave privada correspondente da chave pública associada ao certificado. ● O período de validade do certificado — a data/hora de início e a data/hora de expiração do certificado; indica quando o certificado irá expirar. ● O algoritmo de criptografia simétrica preferido para a chave — indica o algoritmo de criptografia para o qual o proprietário do certificado prefere que as informações sejam criptografadas. Os algoritmos suportados são CAST, IDEA ou Triple-DES. Você pode pensar em um certificado PGP como uma chave pública com um ou mais rótulos vinculados a ele (veja a Figura 1.9 ). Nessas 'etiquetas' você encontrará informações que identificam o proprietário da chave e uma assinatura do proprietário da chave, que afirma que a chave e a identificação andam juntas. (Essa assinatura específica é chamada de autoassinatura; todo certificado PGP contém uma autoassinatura.) Um aspecto único do formato de certificado PGP é que um único certificado pode conter múltiplas assinaturas. Várias ou muitas pessoas podem assinar o par chave/identificação para atestar a sua própria garantia de que a chave pública pertence definitivamente ao proprietário especificado. Se você procurar em um servidor de certificados público, poderá notar que certos certificados, como o do criador do PGP, Phil Zimmermann, contêm muitas assinaturas. Alguns certificados PGP consistem em uma chave pública com vários rótulos, cada um contendo um meio diferente de identificar o proprietário da chave (por exemplo, o nome do proprietário e a conta de e-mail corporativa, o apelido do proprietário e a conta de e-mail residencial, uma fotografia do proprietário — tudo em um certificado). A lista de assinaturas de cada uma dessas identidades pode ser diferente; as assinaturas atestam a autenticidade de que um dos rótulos pertence à chave pública, e não que todos os rótulos da chave sejam autênticos. (Observe que 'autêntico' está nos olhos de quem vê - assinaturas são opiniões, e diferentes pessoas dedicam diferentes níveis de devida diligência na verificação da autenticidade antes de assinar uma chave.) Figura 1-9. Um certificado PGP

Formato de certificado X.509.

X.509 é outro formato de certificado muito comum. Todos os certificados X.509 estão em conformidade com o padrão internacional ITU-T X.509; assim (teoricamente) os certificados X.509 criados para um aplicativo podem ser usados ​​por qualquer aplicativo compatível com X.509. Na prática, porém, diferentes empresas criaram suas próprias extensões para certificados X.509, e nem todas funcionam juntas. Um certificado exige que alguém valide que uma chave pública e o nome do proprietário da chave andam juntos. Com os certificados PGP, qualquer pessoa pode desempenhar o papel de validador. Com certificados X.509, o validador é sempre uma Autoridade Certificadora ou alguém designado por uma CA. (Tenha em mente que os certificados PGP também suportam totalmente uma estrutura hierárquica usando uma CA para validar certificados.)

Um certificado X.509 é uma coleção de um conjunto padrão de campos contendo informações sobre um usuário ou dispositivo e sua chave pública correspondente. O padrão X.509 define quais informações vão para o certificado e descreve como codificá-lo (o formato dos dados). Todos os certificados X.509 possuem os seguintes dados:

O número da versão X.509

— identifica qual versão do padrão X.509 se aplica a este certificado, o que afeta quais informações podem ser especificadas nele. A mais atual é a versão 3.

A chave pública do titular do certificado

— a chave pública do titular do certificado, juntamente com um identificador de algoritmo que especifica a qual sistema criptográfico a chave pertence e quaisquer parâmetros de chave associados.

O número de série do certificado

— a entidade (aplicação ou pessoa) que criou o certificado é responsável por atribuir-lhe um número de série único para distingui-lo de outros certificados que emite. Esta informação é usada de diversas maneiras; por exemplo, quando um certificado é revogado, seu número de série é colocado em uma Lista de Revogação de Certificados ou CRL.

O identificador exclusivo do detentor do certificado

— (ou DN — nome distinto). Este nome pretende ser exclusivo na Internet. Este nome pretende ser exclusivo na Internet. Um DN consiste em múltiplas subseções e pode ser parecido com isto: CN=Bob Allen, OU=Divisão Total de Segurança de Rede, O=Network Associates, Inc., C=EUA (Referem-se ao nome comum, à unidade organizacional, à organização e ao país do sujeito .)

O período de validade do certificado

— a data/hora de início e a data/hora de expiração do certificado; indica quando o certificado irá expirar.

O nome exclusivo do emissor do certificado

— o nome exclusivo da entidade que assinou o certificado. Normalmente é uma CA. A utilização do certificado implica confiar na entidade que assinou este certificado. (Observe que em alguns casos, como certificados de CA raiz ou de nível superior , o emissor assina seu próprio certificado.)

A assinatura digital do emitente

— a assinatura utilizando a chave privada da entidade que emitiu o certificado.

O identificador do algoritmo de assinatura

— identifica o algoritmo usado pela CA para assinar o certificado.

Existem muitas diferenças entre um certificado X.509 e um certificado PGP, mas as mais importantes são as seguintes: você pode criar seu próprio certificado PGP;

● você deve solicitar e receber um certificado X.509 de uma autoridade de certificação

● Os certificados X.509 suportam nativamente apenas um único nome para o proprietário da chave

● Os certificados X.509 suportam apenas uma única assinatura digital para atestar a validade da chave

Para obter um certificado X.509, você deve solicitar a uma CA a emissão de um certificado. Você fornece sua chave pública, prova de que possui a chave privada correspondente e algumas informações específicas sobre você. Em seguida, você assina digitalmente as informações e envia o pacote completo – a solicitação de certificado – para a CA. A CA então realiza algumas diligências para verificar se as informações fornecidas estão corretas e, em caso afirmativo, gera o certificado e o devolve.

Você pode pensar em um certificado X.509 como um certificado de papel padrão (semelhante ao que você recebeu ao concluir uma aula de primeiros socorros básicos) com uma chave pública colada nele. Ele contém seu nome e algumas informações sobre você, além da assinatura da pessoa que o emitiu para você.

Figura 1-10. Um certificado X.509 Provavelmente, o uso mais visível dos certificados X.509 atualmente é em navegadores da web.

Validade e confiança Cada usuário em um sistema de chave pública está vulnerável a confundir uma chave falsa (certificado) com uma chave real. Validade é a confiança de que um certificado de chave pública pertence ao seu suposto proprietário. A validade é essencial em um ambiente de chave pública onde você deve estabelecer constantemente se um determinado certificado é autêntico ou não. Depois de ter certeza de que um certificado pertencente a outra pessoa é válido, você pode assinar a cópia em seu chaveiro para atestar que verificou o certificado e que ele é autêntico. Se quiser que outras pessoas saibam que você deu ao certificado seu selo de aprovação, você pode exportar a assinatura para um servidor de certificados para que outras pessoas possam vê-la.

Conforme descrito na seção Infraestruturas de Chave Pública , algumas empresas designam uma ou mais Autoridades de Certificação (CAs) para indicar a validade do certificado. Em uma organização que usa uma PKI com certificados X.509, é função da CA emitir certificados aos usuários — um processo que geralmente envolve responder à solicitação de certificado do usuário. Em uma organização que usa certificados PGP sem PKI, é função da CA verificar a autenticidade de todos os certificados PGP e depois assinar os bons. Basicamente, o objetivo principal de uma CA é vincular uma chave pública às informações de identificação contidas no certificado e, assim, garantir a terceiros que algum cuidado foi tomado para garantir que esta ligação das informações de identificação e da chave seja válida. O CA é o Grand Pooh-bah da validação em uma organização; alguém em quem todos confiam e, em algumas organizações, como aquelas que utilizam uma PKI, nenhum certificado é considerado válido, a menos que tenha sido assinado por uma CA confiável.

Verificando validade.

Uma maneira de estabelecer a validade é passar por algum processo manual. Existem várias maneiras de fazer isso. Você pode exigir que o destinatário pretendido lhe entregue fisicamente uma cópia de sua chave pública. Mas isto é muitas vezes inconveniente e ineficiente. Outra forma é verificar manualmente a impressão digital do certificado. Assim como as impressões digitais de cada ser humano são únicas, a impressão digital de cada certificado PGP é única. A impressão digital é um hash do certificado do usuário e aparece como uma das propriedades do certificado. No PGP, a impressão digital pode aparecer como um número hexadecimal ou uma série das chamadas palavras biométricas, que são foneticamente distintas e são usadas para facilitar um pouco o processo de identificação da impressão digital. Você pode verificar se um certificado é válido ligando para o proprietário da chave (para que você origine a transação) e pedindo ao proprietário que leia a impressão digital de sua chave para você e compare essa impressão digital com aquela que você acredita ser a verdadeira. Isso funciona se você conhece a voz do proprietário, mas como verificar manualmente a identidade de alguém que você não conhece? Algumas pessoas colocam a impressão digital de sua chave em seus cartões de visita exatamente por esse motivo. Outra forma de estabelecer a validade do certificado de alguém é confiar que um terceiro indivíduo passou pelo processo de validação do mesmo. Uma CA, por exemplo, é responsável por garantir que, antes de emitir um certificado, ele ou ela o verifique cuidadosamente para ter certeza de que a parte da chave pública realmente pertence ao suposto proprietário. Qualquer pessoa que confie na CA considerará automaticamente quaisquer certificados assinados pela CA como válidos. Outro aspecto da verificação da validade é garantir que o certificado não foi revogado. Para obter mais informações, consulte a seção Revogação de certificado .

Estabelecendo confiança.

Você valida certificados. Você confia nas pessoas. Mais especificamente, você confia nas pessoas para validar os certificados de outras pessoas. Normalmente, a menos que o proprietário lhe entregue o certificado, você terá que confiar na palavra de outra pessoa de que ele é válido.

Introdutores meta e confiáveis.

​​Na maioria das situações, as pessoas confiam completamente na CA para estabelecer a validade dos certificados. Isso significa que todos os demais dependem da CA para passar por todo o processo de validação manual. Isso é aceitável até um certo número de usuários ou locais de trabalho e, então, não é possível para a AC manter o mesmo nível de validação de qualidade. Nesse caso, é necessário adicionar outros validadores ao sistema.

Um CA também pode ser um meta- introdutor. Um meta-introdutor confere não apenas validade às chaves, mas também confere a capacidade de confiar nas chaves a outros. Semelhante ao rei que entrega seu selo a seus conselheiros de confiança para que eles possam agir de acordo com sua autoridade, o meta-introdutor permite que outros atuem como introdutores de confiança. Esses introdutores confiáveis ​​podem validar chaves com o mesmo efeito do meta-introdutor. Eles não podem, entretanto, criar novos introdutores confiáveis.

Meta-introdutor e introdutor confiável são termos PGP. Em um ambiente X.509, o meta-introdutor é chamado de Autoridade de Certificação raiz ( CA raiz) e os introdutores confiáveis ​​são Autoridades de Certificação subordinadas . A CA raiz usa a chave privada associada a um tipo de certificado especial denominado certificado CA raiz para assinar certificados. Qualquer certificado assinado pelo certificado CA raiz é visto como válido por qualquer outro certificado assinado pela raiz. Este processo de validação funciona mesmo para certificados assinados por outras CAs no sistema — desde que o certificado da CA raiz tenha assinado o certificado da CA subordinada, qualquer certificado assinado pela CA será considerado válido para outras pessoas dentro da hierarquia. Este processo de verificação de backup por meio do sistema para ver quem assinou cujo certificado é chamado de rastreamento de um caminho de certificação ou cadeia de certificação.

Modelos de confiança.

Em sistemas relativamente fechados, como em uma pequena empresa, é fácil rastrear um caminho de certificação até a CA raiz. No entanto, os usuários muitas vezes precisam se comunicar com pessoas fora do seu ambiente corporativo, incluindo algumas que nunca conheceram, como fornecedores, consumidores, clientes, associados e assim por diante. É difícil estabelecer uma linha de confiança com aqueles em quem sua CA não confia explicitamente. As empresas seguem um ou outro modelo de confiança, que determina como os usuários irão estabelecer a validade do certificado. Existem três modelos diferentes:

Confiança Direta.

Confiança Hierárquica Uma teia de confiança Confiança direta A confiança direta é o modelo de confiança mais simples. Neste modelo, um usuário confia que uma chave é válida porque sabe de onde ela veio. Todos os criptosistemas usam essa forma de confiança de alguma forma. Por exemplo, em navegadores da Web, as chaves raiz da Autoridade de Certificação são diretamente confiáveis ​​porque foram enviadas pelo fabricante. Se houver alguma forma de hierarquia, ela se estenderá a partir desses certificados diretamente confiáveis. No PGP, um usuário que valida as chaves e nunca define outro certificado para ser um introdutor confiável está usando confiança direta. Figura 1-11. Confiança direta

Confiança Hierárquica.

Em um sistema hierárquico, há vários certificados "raiz" a partir dos quais a confiança se estende. Esses certificados podem certificar eles próprios certificados ou podem certificar certificados que certificam ainda outros certificados em alguma cadeia. Considere isso como uma grande “árvore” de confiança. A validade do certificado "folha" é verificada rastreando desde seu certificador até outros certificadores, até que um certificado raiz diretamente confiável seja encontrado.

Figura 1-12. Confiança hierárquica

Teia de Confiança.

Uma teia de confiança abrange ambos os outros modelos, mas também acrescenta a noção de que a confiança está nos olhos de quem vê (que é a visão do mundo real) e a ideia de que mais informação é melhor. É, portanto, um modelo de confiança cumulativa. Um certificado pode ser confiável diretamente ou confiável em alguma cadeia que remonta a um certificado raiz diretamente confiável (o meta-introdutor) ou por algum grupo de introdutores.

Talvez você já tenha ouvido falar do termo seis graus de separação, que sugere que qualquer pessoa no mundo pode determinar algum vínculo com qualquer outra pessoa no mundo usando seis ou menos outras pessoas como intermediários. Esta é uma teia de introdutores. É também a visão de confiança do PGP. PGP usa assinaturas digitais como forma de introdução. Quando qualquer usuário assina a chave de outro, ele ou ela se torna o introdutor dessa chave. À medida que esse processo avança, ele estabelece uma rede de confiança.

Em um ambiente PGP, qualquer usuário pode atuar como autoridade certificadora. Qualquer usuário PGP pode validar o certificado de chave pública de outro usuário PGP. No entanto, tal certificado só é válido para outro usuário se a parte confiável reconhecer o validador como um introdutor confiável. (Ou seja, você confia na minha opinião de que as chaves dos outros são válidas apenas se você me considerar um apresentador confiável. Caso contrário, minha opinião sobre a validade das outras chaves é discutível.) Armazenados no chaveiro público de cada usuário estão indicadores de

● se o usuário considera ou não uma chave específica válida

● o nível de confiança que o usuário deposita na chave que o proprietário da chave pode servir como certificador das chaves de terceiros

Você indica, na sua cópia da minha chave, se acha que meu julgamento conta. Na verdade, é um sistema de reputação: certas pessoas têm a reputação de fornecer boas assinaturas e as pessoas confiam nelas para atestar a validade de outras chaves.

Níveis de confiança no PGP.

O nível mais alto de confiança em uma chave, a confiança implícita , é a confiança em seu próprio par de chaves. O PGP assume que se você possui a chave privada, você deve confiar nas ações da sua chave pública relacionada. Quaisquer chaves assinadas pela sua chave implicitamente confiável são válidas.

Existem três níveis de confiança que você pode atribuir à chave pública de outra pessoa:

● Confiança total ● Confiança marginal ● Não confiável (ou não confiável)

Para tornar as coisas confusas, também existem três níveis de validade:

● Válido ● Marginalmente válido ● Inválido

Para definir a chave de outra pessoa como um introdutor confiável, você

1. Comece com uma chave válida, que seja.
2. assinado por você ou

3. assinado por outro apresentador confiável e então

4. Defina o nível de confiança que você acha que o proprietário da chave tem direito.

Por exemplo, suponha que seu chaveiro contenha a chave de Alice. Você validou a chave de Alice e indica isso assinando-a. Você sabe que Alice é uma verdadeira defensora da validação de chaves de outras pessoas. Portanto, você atribui a chave dela com confiança total. Isso faz de Alice uma Autoridade Certificadora. Se Alice assinar a chave de outra pessoa, ela aparecerá como Válida em seu chaveiro. O PGP requer uma assinatura Totalmente confiável ou duas assinaturas Marginalmente confiáveis ​​para estabelecer uma chave como válida. O método do PGP de considerar dois Marginais iguais a um Completo é semelhante a um comerciante que solicita duas formas de identificação. Você pode considerar Alice bastante confiável e também considerar Bob bastante confiável. Qualquer um deles sozinho corre o risco de assinar acidentalmente uma chave falsificada, portanto, você pode não depositar total confiança em nenhum deles. No entanto, as probabilidades de ambos os indivíduos terem assinado a mesma chave falsa são provavelmente pequenas.

Revogação de certificado.

Os certificados só são úteis enquanto são válidos. Não é seguro simplesmente presumir que um certificado é válido para sempre. Na maioria das organizações e em todas as PKIs, os certificados têm uma vida útil restrita. Isso restringe o período em que um sistema fica vulnerável caso ocorra um comprometimento do certificado.

Os certificados são assim criados com um período de validade programado: uma data/hora de início e uma data/hora de expiração. Espera-se que o certificado seja utilizável durante todo o seu período de validade (seu tempo de vida ). Quando o certificado expirar, ele não será mais válido, pois a autenticidade do seu par chave/identificação não estará mais garantida. (O certificado ainda pode ser usado com segurança para reconfirmar informações que foram criptografadas ou assinadas dentro do período de validade – no entanto, ele não deve ser confiável para tarefas criptográficas futuras.)

Existem também situações em que é necessário invalidar um certificado antes da sua data de expiração, como quando o titular do certificado termina o contrato de trabalho com a empresa ou suspeita que a chave privada correspondente do certificado foi comprometida. Isso é chamado de revogação. Um certificado revogado é muito mais suspeito do que um certificado expirado. Os certificados expirados são inutilizáveis, mas não apresentam a mesma ameaça de comprometimento que um certificado revogado. Qualquer pessoa que tenha assinado um certificado pode revogar a sua assinatura no certificado (desde que utilize a mesma chave privada que criou a assinatura). Uma assinatura revogada indica que o signatário não acredita mais que a chave pública e as informações de identificação pertencem uma à outra, ou que a chave pública do certificado (ou a chave privada correspondente) foi comprometida. Uma assinatura revogada deve ter quase tanto peso quanto um certificado revogado. Com certificados X.509, uma assinatura revogada é praticamente igual a um certificado revogado, visto que a única assinatura no certificado é aquela que o tornou válido em primeiro lugar – a assinatura da CA. Os certificados PGP fornecem o recurso adicional de que você pode revogar todo o seu certificado (não apenas as assinaturas nele) se você achar que o certificado foi comprometido. Somente o proprietário do certificado (o detentor da chave privada correspondente) ou alguém que o proprietário do certificado tenha designado como revogador pode revogar um certificado PGP. (Designar um revogador é uma prática útil, pois muitas vezes é a perda da senha da chave privada correspondente do certificado que leva um usuário PGP a revogar seu certificado - uma tarefa que só é possível se alguém tiver acesso à chave privada. ) Somente o emissor do certificado pode revogar um certificado X.509.

Comunicar que um certificado foi revogado.

Quando um certificado é revogado, é importante conscientizar os usuários potenciais do certificado de que ele não é mais válido. Com certificados PGP, a maneira mais comum de comunicar que um certificado foi revogado é publicá-lo em um servidor de certificados para que outras pessoas que desejem se comunicar com você sejam avisadas para não usar essa chave pública. Em um ambiente PKI, a comunicação de certificados revogados é mais comumente obtida por meio de uma estrutura de dados chamada Lista de Revogação de Certificados, ou CRL, que é publicada pela CA. A CRL contém uma lista validada com carimbo de data e hora de todos os certificados revogados e não expirados no sistema. Os certificados revogados permanecem na lista apenas até expirarem e, em seguida, são removidos da lista — isso evita que a lista fique muito longa. A CA distribui a CRL aos usuários em algum intervalo programado regularmente (e potencialmente fora do ciclo, sempre que um certificado é revogado). Teoricamente, isso impedirá que os usuários usem involuntariamente um certificado comprometido. É possível, no entanto, que haja um período de tempo entre as CRLs em que um certificado recentemente comprometido seja usado.

O que é uma senha?

A maioria das pessoas está familiarizada com a restrição de acesso a sistemas de computador por meio de uma senha, que é uma sequência única de caracteres que um usuário digita como código de identificação.

Uma senha longa é uma versão mais longa de uma senha e, em teoria, mais segura. Normalmente composta por várias palavras, uma frase secreta é mais segura contra ataques de dicionário padrão, em que o invasor tenta todas as palavras do dicionário na tentativa de determinar sua senha. As melhores senhas são relativamente longas e complexas e contêm uma combinação de letras maiúsculas e minúsculas, caracteres numéricos e de pontuação. O PGP usa uma senha para criptografar sua chave privada em sua máquina. Sua chave privada é criptografada em seu disco usando um hash de sua senha como chave secreta. Você usa a senha para descriptografar e usar sua chave privada. Uma senha deve ser difícil de esquecer e difícil de ser adivinhada por outras pessoas. Deve ser algo já firmemente enraizado na sua memória de longo prazo, em vez de algo que você invente do zero. Por que? Porque se você esquecer sua senha, você estará sem sorte. Sua chave privada é total e absolutamente inútil sem sua senha e nada pode ser feito a respeito. Lembra-se da citação anterior neste capítulo?

PGP é a criptografia que manterá os principais governos fora dos seus arquivos. Certamente também o manterá fora de seus arquivos. Tenha isso em mente quando decidir alterar sua senha para a piada daquela piada que você nunca consegue lembrar.

Divisão de chave.

Dizem que um segredo não é segredo se for conhecido por mais de uma pessoa. Compartilhar um par de chaves privadas representa um grande problema. Embora não seja uma prática recomendada, às vezes é necessário compartilhar um par de chaves privadas. Chaves de assinatura corporativa, por exemplo, são chaves privadas usadas por uma empresa para assinar – por exemplo – documentos legais, informações pessoais confidenciais ou comunicados de imprensa para autenticar sua origem. Nesse caso, vale a pena que vários membros da empresa tenham acesso à chave privada. No entanto, isto significa que qualquer indivíduo pode agir plenamente em nome da empresa. Nesse caso, é aconselhável dividir a chave entre várias pessoas, de modo que mais de uma ou duas pessoas apresentem um pedaço da chave para reconstituí-la em condições utilizáveis. Se poucas peças da chave estiverem disponíveis, a chave ficará inutilizável. Alguns exemplos são dividir uma chave em três partes e exigir duas delas para reconstituir a chave, ou dividi-la em duas partes e exigir ambas as peças. Se uma conexão de rede segura for usada durante o processo de reconstituição, os acionistas da chave não precisam estar fisicamente presentes para aderirem novamente à chave.

Cashu is a free and open-source Chaumian ecash protocol built for Bitcoin. Ecash is a digital bearer token that is stored on a user's device, very similar to physical cash. The Cashu protocol allows you to build applications such as wallets or voucher systems. Cashu is designed to be private, secure and scalable. Transactions are instant and nearly free.

What is Cashu?

Cashu is an ecash protocol that is integrated with the Bitcoin protocol. An Ecash system consists of two parts, the mint and the Ecash wallet. Anyone can run a mint for their application, be it a wallet, a web paywall, paid streaming services, or a voucher and rewards system for a super market. Ecash transactions between users or from the user to a service provider respect the user's privacy. A mint does not store a database of user accounts and their activity which protects users of an Ecash system from leaks their private data to hackers and can provide stronger censorship resistant than classical payment systems.

The Cashu Protocol

Cashu is an ecash protocol built for Bitcoin. It is an open protocol which means that everyone can write their own software to interact with other Cashu apps. Applications that follow the specifications will be compatible with the rest of the ecosystem.

Cashu wallets

Nutshell

Desde a sua criação, Bitcoin tem sido alvo de debates sobre a sua utilização em atividades ilícitas. muitos críticos afirmam que Bitcoin facilita crimes como lavagem de dinheiro e financiamento de atividades ilegais, devido à sua natureza descentralizada e à possibilidade de realizar transações sem intermediários. no entanto, a realidade é mais complexa e muitas dessas alegações são exageradas ou baseadas em mitos. na verdade, a maioria das transações com Bitcoin são legítimas e até mais rastreáveis do que muitos imaginam.

O mito: Bitcoin é a principal moeda para criminosos

Um dos maiores mitos sobre Bitcoin é a ideia de que ele é amplamente utilizado por criminosos devido ao seu suposto anonimato. este argumento tornou-se popular principalmente devido a casos como o da Silk Road, um mercado negro online desmantelado pelas autoridades em 2013, onde Bitcoin era usado para transações ilegais. no entanto, os dados mais recentes mostram que apenas uma pequena fração das transações em Bitcoin está relacionada com atividades ilícitas.

Além disso, ao contrário do dinheiro em espécie, que é quase impossível de rastrear, todas as transações de Bitcoin são registadas publicamente na blockchain ou timechain. isto significa que qualquer pagamento feito com Bitcoin pode ser analisado e seguido, tornando mais difícil esconder transações suspeitas a longo prazo.

A realidade: Bitcoin é transparente e rastreável

Ao contrário do que muitos pensam, Bitcoin não é completamente anónimo, mas sim pseudónimo. todas as transações ficam registadas na blockchain ou timechain, permitindo que autoridades e analistas de dados consigam seguir os fluxos de dinheiro com precisão. várias empresas especializadas em análise forense de blockchain ou timechain já ajudaram a identificar e desmantelar redes criminosas que tentavam utilizar Bitcoin para fins ilícitos.

Governos e autoridades, como o FBI e a Europol, têm utilizado esta característica para combater crimes financeiros. na prática, criminosos que tentam usar Bitcoin acabam frequentemente por ser apanhados devido à transparência do sistema. por isso, a ideia de que Bitcoin é um refúgio seguro para criminosos não corresponde à realidade.

O uso ilícito de moedas fiduciárias é muito maior

Se compararmos Bitcoin com as moedas fiduciárias tradicionais, como o euro ou o dólar, percebemos que estas são muito mais utilizadas para atividades ilícitas. segundo relatórios de organizações internacionais, a lavagem de dinheiro e o financiamento de crimes organizados ocorrem predominantemente através de bancos, empresas fictícias e dinheiro em espécie.

Por exemplo, em escândalos financeiros globais, como o Panama Papers e o caso do banco HSBC envolvido em lavagem de dinheiro para cartéis, os meios tradicionais foram os preferidos para esconder fortunas ilegais. apesar disso, Bitcoin continua a ser injustamente associado ao crime, enquanto os verdadeiros mecanismos de financiamento ilícito continuam a operar dentro do sistema financeiro convencional.

Resumindo, o mito de que Bitcoin é um meio privilegiado para atividades ilícitas tem sido amplamente desmentido por dados e investigações. apesar de alguns criminosos terem tentado usá-lo no passado, a realidade é que Bitcoin é um sistema financeiro mais transparente e rastreável do que o dinheiro tradicional. a grande maioria das suas transações é legítima e, à medida que a adoção cresce, Bitcoin continua a provar o seu valor como um meio seguro e descentralizado para transações financeiras.

O Bitcoin tem revolucionado a forma como as pessoas realizam transações financeiras em todo o mundo. Sendo uma moeda digital descentralizada, oferece novas oportunidades para pagamentos no comércio eletrónico e transferências internacionais de dinheiro. A sua rapidez, segurança e baixos custos tornam-no uma alternativa eficiente aos métodos tradicionais, eliminando intermediários e facilitando transações globais.

Bitcoin no comércio eletrónico

O comércio eletrónico tem crescido exponencialmente, e o Bitcoin surge como uma solução inovadora para pagamentos online. Grandes retalhistas e pequenas empresas estão a começar a aceitar Bitcoin como forma de pagamento, oferecendo benefícios tanto para os comerciantes como para os consumidores.

Vantagens do Bitcoin para o comércio eletrónico:

Baixas taxas de transação: ao contrário dos cartões de crédito e plataformas de pagamento que cobram taxas elevadas, as transações em Bitcoin apresentam, geralmente, custos mais reduzidos. Isto beneficia os comerciantes, que podem diminuir despesas e oferecer preços mais competitivos aos clientes.

Eliminação de chargebacks: no sistema tradicional, os chargebacks (reembolsos forçados pelos bancos ou operadoras de cartão) representam uma preocupação para os lojistas. Como as transações em Bitcoin são irreversíveis, os comerciantes evitam fraudes e disputas.

Acesso global: qualquer pessoa com acesso à Internet pode pagar com Bitcoin, independentemente da sua localização. Isto permite às empresas expandirem o seu mercado internacionalmente, sem depender de bancos ou sistemas de pagamento locais.

Privacidade e segurança: as transações em Bitcoin protegem a identidade do utilizador, oferecendo maior privacidade em comparação com pagamentos através de cartão de crédito ou transferências bancárias. Além disso, como não há necessidade de partilhar dados pessoais, o risco de roubo de informações é reduzido.

Desafios do Uso do Bitcoin no Comércio Eletrónico:

Volatilidade: o preço do Bitcoin pode oscilar rapidamente, o que dificulta a fixação de preços para produtos e serviços. No entanto, alguns comerciantes utilizam serviços de pagamento que convertem automaticamente Bitcoin em moeda fiduciária, minimizando esse risco.

Adoção limitada: apesar do crescimento, a aceitação do Bitcoin ainda não é universal. Muitas lojas e plataformas populares ainda não o adotaram, o que pode dificultar a sua utilização em compras diárias.

Tempo de confirmação: embora o Bitcoin seja mais rápido do que as transferências bancárias tradicionais, o tempo de confirmação pode variar consoante a taxa de rede paga. Algumas soluções, como a Lightning Network, estão a ser desenvolvidas para tornar os pagamentos instantâneos.

Bitcoin na remessa de dinheiro

O envio de dinheiro para o estrangeiro sempre foi um processo burocrático, dispendioso e demorado. Serviços tradicionais, como os bancos e empresas de transferência de dinheiro, cobram taxas elevadas e podem demorar dias a concluir uma transação. O Bitcoin, por outro lado, oferece uma alternativa eficiente para remessas globais, permitindo que qualquer pessoa envie e receba dinheiro de forma rápida e económica.

Benefícios do Bitcoin para remessas:

Custos reduzidos: enquanto os bancos e empresas como a Western Union cobram elevadas taxas para transferências internacionais, o Bitcoin permite o envio de dinheiro com custos mínimos, independentemente do montante ou do destino.

Velocidade nas transações: as transferências bancárias internacionais podem demorar vários dias a serem concluídas, especialmente em países com uma infraestrutura financeira limitada. Com o Bitcoin, o dinheiro pode ser enviado para qualquer parte do mundo em poucos minutos ou horas.

Acessibilidade global: em regiões onde o sistema bancário é restrito ou ineficiente, o Bitcoin possibilita que as pessoas recebam dinheiro sem depender de bancos. Isto é particularmente útil em países em desenvolvimento, onde as remessas internacionais são uma fonte essencial de rendimento.

Independência de intermediários: o Bitcoin opera de forma descentralizada, sem necessidade de recorrer a bancos ou empresas de transferência. Isto significa que as pessoas podem enviar dinheiro diretamente para amigos e familiares sem intermediários.

Desafios das remessas com Bitcoin:

Conversão para moeda local: apesar de o Bitcoin poder ser recebido instantaneamente, muitas pessoas ainda precisam de convertê-lo em moeda local para o utilizar. Isso pode envolver custos adicionais e depender da disponibilidade de serviços de câmbio.

Adoção e conhecimento: nem todos compreendem o funcionamento do Bitcoin, o que pode dificultar a sua adoção generalizada para remessas. No entanto, a crescente educação financeira sobre o tema pode ajudar a ultrapassar essa barreira.

Regulamentação e restrições: alguns governos impõem restrições ao uso do Bitcoin, tornando as remessas mais complicadas. A evolução das regulamentações pode afetar a facilidade de uso em determinados países.

Resumindo, o Bitcoin está a transformar o comércio eletrónico e as remessas de dinheiro em todo o mundo. A sua capacidade de eliminar intermediários, reduzir custos e oferecer pagamentos rápidos e seguros torna-o uma alternativa viável aos sistemas financeiros tradicionais.

No comércio eletrónico, proporciona benefícios para lojistas e consumidores, reduzindo taxas e melhorando a privacidade. No setor das remessas, facilita a transferência de dinheiro para qualquer parte do mundo, especialmente para aqueles que vivem em países com sistemas bancários pouco eficientes.

Apesar dos desafios, a adoção do Bitcoin continua a crescer, impulsionada por soluções inovadoras e pelo reconhecimento do seu potencial como meio de pagamento global. À medida que mais empresas e indivíduos aderirem a esta tecnologia, a sua presença no comércio eletrónico e nas remessas internacionais será cada vez mais relevante.

Bitcoin, desde o seu surgimento em 2009, tem gerado uma variedade de histórias de sucesso e fracasso. Algumas dessas histórias são de pessoas que investiram cedo na criptomoeda e colheram os frutos de sua visão precoce, enquanto outras refletem os altos e baixos que caracterizam o mercado altamente volátil de Bitcoin. Ao longo dos anos, muitas dessas histórias tornaram-se emblemáticas, servindo tanto de inspiração quanto de alerta para quem entra nesse mercado.

Histórias de sucesso

O caso de Laszlo Hanyecz – A pizza de 10.000 Bitcoins Uma das histórias mais icônicas e, ao mesmo tempo, um exemplo do potencial e da volatilidade do Bitcoin, envolve Laszlo Hanyecz, um programador americano. Em 2010, Hanyecz pagou 10.000 bitcoins por duas pizzas. Na época, o valor das criptomoedas era tão baixo que essa transação passou despercebida, mas, em retrospectiva, os 10.000 bitcoins pagos por uma simples refeição valeriam centenas de milhões de dólares nos anos seguintes, quando o preço do Bitcoin disparou.

Essa história, muitas vezes citada, é um lembrete da enorme valorização do Bitcoin desde os seus primeiros dias. Embora Hanyecz não tenha ficado rico com essa transação, a história da "pizza de 10.000 bitcoins" tornou-se uma metáfora para o crescimento do Bitcoin, mostrando como uma pequena quantidade da moeda no início poderia ter mudado a vida de alguém para sempre.

O caso de Michael Saylor e a MicroStrategy no presente Michael Saylor, CEO da MicroStrategy, é outro exemplo de sucesso no mundo do Bitcoin. Em 2020, Saylor decidiu transformar a sua empresa numa das primeiras grandes corporações a investir pesadamente em Bitcoin, comprando mais de 100.000 bitcoins. A decisão foi inicialmente vista com ceticismo, mas ao longo do tempo, o preço do Bitcoin subiu consideravelmente, fazendo com que o investimento de Saylor se tornasse extremamente lucrativo. Para ele, o Bitcoin não era apenas um investimento especulativo, mas uma maneira de proteger a sua empresa da inflação e da desvalorização da moeda fiduciária.

Este caso é um exemplo de como uma aposta estratégica em Bitcoin pode resultar em grandes lucros para quem tem visão de longo prazo e confiança no potencial do ativo. A MicroStrategy tornou-se um dos maiores detentores de Bitcoin no mundo corporativo, e Saylor ganhou reconhecimento por ser um defensor do Bitcoin no mundo empresarial.

Histórias de fracasso

O caso de James Howells – O desaparecimento de 8.000 Bitcoins James Howells, um ex-empregado de TI de Gales, é um exemplo clássico de como a volatilidade e a negligência podem resultar em grandes perdas. Em 2013, Howells, que estava a minerar Bitcoin em casa, acumulou 8.000 bitcoins, que valiam cerca de 5.000 libras na época. Quando o mercado estava em queda, ele decidiu limpar o seu computador antigo e jogá-lo fora, sem perceber que os bitcoins estavam guardados em uma carteira digital nesse dispositivo.

Após a ascensão do preço do Bitcoin, Howells tentou recuperar o disco rígido, que estava enterrado numa lixeira em um aterro sanitário. Apesar das tentativas de convencer a cidade a permitir a escavação do aterro, o pedido foi negado, e ele nunca conseguiu recuperar os bitcoins. Este caso é um lembrete de como, sem a devida segurança e cuidado, até mesmo grandes fortunas podem ser perdidas no mundo das criptomoedas.

O colapso da Mt. Gox – A maior exchange de Bitcoin da história Uma das maiores histórias de fracasso envolvendo Bitcoin está relacionada à exchange Mt. Gox, uma plataforma de negociação de Bitcoin que, em 2014, faliu após alegadamente perder cerca de 850.000 bitcoins dos seus clientes, num valor superior a 450 milhões de dólares na época. A Mt. Gox foi, por um período, a maior exchange de Bitcoin do mundo, mas a sua falência foi um marco negativo na história do Bitcoin.

A falência da Mt. Gox foi causada por uma combinação de hacking, erros internos de segurança e má gestão. Embora alguns dos bitcoins perdidos tenham sido recuperados mais tarde, muitos investidores ficaram devastados pela perda dos seus fundos. Este incidente trouxe à tona a importância da segurança nas exchanges de Bitcoin e da responsabilidade das plataformas financeiras no manejo das criptomoedas de seus clientes.

O impacto da volatilidade e da adoção no mercado

As histórias de sucesso e fracasso envolvendo Bitcoin não são apenas anedotas, mas refletem a natureza imprevisível e arriscada do mercado de criptomoedas. O preço de Bitcoin pode flutuar drasticamente, o que significa que investidores podem tanto fazer grandes fortunas quanto sofrer grandes perdas. Enquanto alguns vêem Bitcoin como uma forma de alcançar a liberdade financeira e proteger-se contra a inflação, outros enfrentam o risco de perder tudo, como demonstrado pelos casos de fracasso.

A adoção crescente de Bitcoin em mercados emergentes, bem como a entrada de investidores institucionais, como a MicroStrategy e o próprio Elon Musk, são indicativos de que o Bitcoin está a ser cada vez mais reconhecido como uma alternativa legítima ao sistema financeiro tradicional. No entanto, as falências de exchanges e as perdas de grandes quantidades de Bitcoin destacam a necessidade de uma abordagem prudente e de uma infraestrutura mais robusta para garantir a segurança e a confiança dos utilizadores.

Resumindo, as histórias de sucesso e fracasso em torno do Bitcoin são um reflexo da natureza volátil e emergente desta moeda digital. Enquanto alguns ganharam milhões, outros perderam fortunas devido à falta de precaução, erros de gestão ou simplesmente pelo preço imprevisível da criptomoeda. Através destas histórias, fica claro que, embora o Bitcoin tenha o potencial de gerar grandes recompensas, ele também apresenta riscos significativos. Para aqueles que entram nesse mercado, é crucial estar preparado e consciente dos desafios que podem surgir, garantindo segurança e adotando uma estratégia de longo prazo para lidar com as incertezas e volatilidade do mercado.

On the one hand, Iran is justified to defend itself. On the other hand, nuclear bombs are bad.

On the one hand, the US are the only ones that have used nuclear bombs on civilians.

On the other hand, I live in the US. That makes me especially scared of nukes going off on US soil.

Both hands now:

Guess where nukes need to be to go off on US soil?

Guess where the US military stores and transports a lot of nukes?

Did you know they've lost more than one?

I don't want nuclear bombs being stored and transported near me by people so incompetent, they've lost a single one ever. Let alone multiple.

Why would I trust they'll never let one go off where it's not supposed to?

If Iran had nuclear bombs, they might hit me someday when climate change makes Iran uninhabitable and the world's refugee policy is "let them die." That hasn't happened yet.

They have no reason to end the world in a nuclear apocalypse right now. The position they're in right now is simple self-defense. There's no need for suicide.

The US doesn't need to do it either, but the US are the ones escalating the risk. The US military are the ones storing and transporting and losing nuclear bombs where I live. They're the ones I'm worried about nuking me today, while I'm typing this.

Right now, today, Iran could secretly have nukes (we "lost") and their nukes still wouldn't be as much of a threat to me as the ones here.

We have nuclear submarines. We have a lot of less inhabited land in Alaska. We could start by banning the military from storing or transporting nuclear bombs in the 48 contiguous states.

But the end goal should be to fully denuclearize, so that we can reasonably ask the rest of the world to come together on that idea. I've been saying this for a few years.

The US nuclear arsenal is ostensibly the most powerful on earth. We invented the things.

The US has bragged for decades about having the most powerful military on Earth. The US has the GBU-43/B MOAB, a conventional bomb that hits as hard as a small nuke, but without the radiation. The US has military bases all over the world.

The US has nuclear armed allies who would defend us until other counterparties join in denuclearizing. Our nukes aren't the only powerful leverage we can use to make sure these allies don't betray us.

Without this arsenal, we wouldn't be sitting ducks.

We would simply be much safer from the insane military-industrial-complex terrorists endangering us all today.

We would still know how to make nukes. We don't need to keep practicing to hone that skill; there aren't even nuclear tests anymore because the mad scientists have all agreed they've gone too far already. Do you realize how far that means we've gone?

A lot of the damage so far has been indirect. The nuclear arms race left particles of irradiated material in the air worldwide, still measurable today, still part of the pollution causing today's increased global cancer rates.

Recent escalation has politicians talking about starting nuclear testing again - just to terrorize the world with more of this indirect damage, when we've already done all the testing we could need.

Iran hasn't done any nuclear detonation tests. They've been very hesitant to try to catch up on this insanity.

I remind you again, nuclear bombs have been used directly on civilians twice. Of course, both times were the US military at the end of World War II. Those war-traumatized, broken people thought it was OK to go again, after doing it once.

Today's war-traumatized, broken people still seem to think that wasn't wrong.

How can we let distrustful and mentally unstable loyalists keep so many nukes, and yet blow up Iran over it?

Mutually assured destruction is not a sane goal. Mutually assured survival is a sane goal.

Let's make the atomic age the last chapter of a spacefaring race's dark, wartorn origin story; not the last chapter of human history altogether.

It's time for people to wake up and come together like never before.

Contribute to keep No Bullshit Bitcoin news going.

• The latest firmware updates for COLDCARD devices introduce two major features: COLDCARD Co-sign (CCC) and Key Teleport between two COLDCARD Q devices using QR codes and/or NFC with a website.

What's new

• COLDCARD Co-Sign: When CCC is enabled, a second seed called the Spending Policy Key (Key C) is added to the device. This seed works with the device's Main Seed and one or more additional XPUBs (Backup Keys) to form 2-of-N multisig wallets.
  • The spending policy functions like a hardware security module (HSM), enforcing rules such as magnitude and velocity limits, address whitelisting, and 2FA authentication to protect funds while maintaining flexibility and control, and is enforced each time the Spending Policy Key is used for signing.
  • When spending conditions are met, the COLDCARD signs the partially signed bitcoin transaction (PSBT) with the Main Seed and Spending Policy Key for fund access. Once configured, the Spending Policy Key is required to view or change the policy, and violations are denied without explanation.

"You can override the spending policy at any time by signing with either a Backup Key and the Main Seed or two Backup Keys, depending on the number of keys (N) in the multisig."

• A step-by-step guide for setting up CCC is available here.

• Key Teleport for Q devices allows users to securely transfer sensitive data such as seed phrases (words, xprv), secure notes and passwords, and PSBTs for multisig. It uses QR codes or NFC, along with a helper website, to ensure reliable transmission, keeping your sensitive data protected throughout the process.

  • For more technical details, see the protocol spec.

"After you sign a multisig PSBT, you have option to “Key Teleport” the PSBT file to any one of the other signers in the wallet. We already have a shared pubkey with them, so the process is simple and does not require any action on their part in advance. Plus, starting in this firmware release, COLDCARD can finalize multisig transactions, so the last signer can publish the signed transaction via PushTX (NFC tap) to get it on the blockchain directly."

• Multisig transactions are finalized when sufficiently signed. It streamlines the use of PushTX with multisig wallets.
• Signing artifacts re-export to various media. Users are now provided with the capability to export signing products, like transactions or PSBTs, to alternative media rather than the original source. For example, if a PSBT is received through a QR code, it can be signed and saved onto an SD card if needed.
• Multisig export files are signed now. Public keys are encoded as P2PKH address for all multisg signature exports. Learn more about it here.
• NFC export usability upgrade: NFC keeps exporting until CANCEL/X is pressed.
• Added Bitcoin Safe option to Export Wallet.
• 10% performance improvement in USB upload speed for large files.
• Q: Always choose the biggest possible display size for QR.

Fixes

• Do not allow change Main PIN to same value already used as Trick PIN, even if Trick PIN is hidden.
• Fix stuck progress bar under Receiving... after a USB communications failure.
• Showing derivation path in Address Explorer for root key (m) showed double slash (//).
• Can restore developer backup with custom password other than 12 words format.
• Virtual Disk auto mode ignores already signed PSBTs (with “-signed” in file name).
• Virtual Disk auto mode stuck on “Reading…” screen sometimes.
• Finalization of foreign inputs from partial signatures. Thanks Christian Uebber!
• Temporary seed from COLDCARD backup failed to load stored multisig wallets.
• Destroy Seed also removes all Trick PINs from SE2.
• Lock Down Seed requires pressing confirm key (4) to execute.
• Q only: Only BBQr is allowed to export Coldcard, Core, and pretty descriptor.

Bitcoin, desde o seu lançamento em 2009, tem atraído a atenção de diversos investidores e visionários que acreditam no seu potencial para revolucionar o sistema financeiro global. Ao longo dos anos, várias figuras se destacaram no movimento em torno da criptomoeda, seja como pioneiros que ajudaram a fundá-la, ou como investidores que apostaram no seu futuro. Estes indivíduos desempenharam papéis cruciais no desenvolvimento do Bitcoin, na sua adoção crescente e na sua legitimação no mercado financeiro.

Satoshi Nakamoto

O maior pioneiro do Bitcoin é, sem dúvida, o seu criador, Satoshi Nakamoto. Embora o nome seja um pseudónimo, a sua contribuição para a criação e lançamento do Bitcoin foi fundamental. Em 2008, Nakamoto publicou o famoso whitepaper intitulado "Bitcoin: A Peer-to-Peer Electronic Cash System", detalhando a ideia de uma moeda digital descentralizada que poderia operar sem a necessidade de uma autoridade central, como um banco. Em 2009, ele lançou o software Bitcoin e minerou o primeiro bloco da blockchain, conhecido como "bloco gênese".

Satoshi Nakamoto permaneceu uma figura misteriosa, nunca revelando a sua verdadeira identidade. Ele foi responsável pelo desenvolvimento inicial do protocolo, mas desapareceu gradualmente da cena pública por volta de 2011, deixando o projeto nas mãos de uma comunidade crescente de desenvolvedores. A sua identidade permanece desconhecida até hoje, mas o seu impacto na criação de uma nova era digital é inegável.

Hal Finney

Hal Finney foi um dos primeiros colaboradores de Nakamoto e é amplamente reconhecido como o primeiro a receber uma transação de Bitcoin. Em janeiro de 2009, Finney recebeu 10 bitcoins de Nakamoto como parte de um teste de transação, tornando-se uma das primeiras pessoas a acreditar no projeto. Finney, que era um programador e investigador de segurança, desempenhou um papel importante no desenvolvimento técnico do Bitcoin e ajudou a popularizá-lo nas suas primeiras fases.

Finney foi uma figura respeitada na comunidade de criptografia e um defensor do movimento de descentralização digital. Ele continuou a apoiar o Bitcoin até sua morte, em 2014, e é lembrado como um dos maiores pioneiros da moeda digital.

Roger Ver

Roger Ver, conhecido como o "Bitcoin Jesus", foi um dos primeiros investidores e “evangelistas” do Bitcoin. Ver ficou fascinado com o conceito de uma moeda descentralizada e investiu cedo em vários projetos relacionados ao Bitcoin. Ele foi um dos primeiros a reconhecer o potencial disruptivo do Bitcoin, defendendo a sua adoção global e promovendo o seu uso como meio de pagamento.

Ver também foi uma das figuras centrais na criação de empresas e iniciativas que ajudaram a impulsionar o ecossistema Bitcoin. Embora tenha sido uma figura polêmica, devido às suas opiniões fortes sobre a escalabilidade do Bitcoin, e tenha se afastado da blockchain original do Bitcoin em favor do Bitcoin Cash, sua contribuição para a popularização da moeda é inegável.

Tim Draper

Tim Draper é um dos investidores mais conhecidos no espaço do Bitcoin e um defensor da sua adoção em larga escala. Em 2014, Draper comprou quase 30.000 bitcoins, que foram apreendidos pelo governo dos Estados Unidos em uma operação contra o mercado Silk Road. Draper fez essa compra por cerca de 19 milhões de dólares, e ele tem sido uma figura-chave na promoção do Bitcoin como uma alternativa viável às moedas fiduciárias.

Draper, um investidor de risco de renome e fundador da Draper Associates, é conhecido por sua visão de longo prazo e pela sua confiança na ascensão das criptomoedas. Ele tem defendido o Bitcoin como uma ferramenta para democratizar o acesso ao dinheiro e acredita que a adoção do Bitcoin vai crescer exponencialmente nos próximos anos.

Michael Saylor

Michael Saylor, CEO da MicroStrategy, é uma figura importante na adoção institucional do Bitcoin. Em 2020, Saylor fez uma aposta significativa ao comprar mais de 100.000 bitcoins para a sua empresa, transformando-a na primeira companhia pública a ter Bitcoin como reserva de valor no seu balanço. Saylor tem defendido publicamente o Bitcoin como uma proteção contra a inflação e uma alternativa mais segura ao dinheiro fiduciário. A sua aposta ajudou a legitimar o Bitcoin no mundo corporativo e inspirou outras empresas a seguir o seu exemplo.

A sua posição em relação ao Bitcoin tem sido clara: ele acredita que o futuro financeiro do mundo está no Bitcoin, e a sua empresa serve como um exemplo para outras grandes corporações a adotarem a moeda digital.

Resumindo, os pioneiros e investidores que contribuíram para o crescimento e a difusão do Bitcoin desempenharam papéis vitais na evolução desta tecnologia disruptiva. Desde o misterioso Satoshi Nakamoto até figuras como Hal Finney, Roger Ver, Tim Draper e Michael Saylor, o Bitcoin tem sido moldado por pessoas com uma visão única sobre o futuro do dinheiro e da liberdade financeira. Através da sua perseverança e crença no potencial do Bitcoin, esses indivíduos ajudaram a estabelecer as bases para a adoção global da moeda digital, transformando-a de uma ideia inovadora em uma força revolucionária no sistema financeiro. O futuro do Bitcoin dependerá, em grande parte, da continuidade da sua evolução e da adoção por mais pessoas e instituições, mas é indiscutível que os pioneiros e investidores desempenharam um papel fundamental na sua ascensão.

Perché chiamare Bisanzio questa community? Ci sono due ragioni principali: una legata all'economia, l’altra alla tecnologia. Vediamole!

Costantino e il solidus

Quando Costantino il Grande prese in mano le redini dell'impero, ne risollevò le sorti adottando riforme economiche lungimiranti. Tra gli impegni assunti, il più importante fu quello di mantenere il solidus a 4,5 grammi d'oro senza tagli o svalutazioni, coniandolo in grandi quantità a partire dal 312 d.C.. Spostò poi la capitale verso est, a Bisanzio, nel punto di incontro tra Asia ed Europa, dando vita all'Impero Romano d'Oriente, che adottò il solidus come moneta.

Mentre Roma continuava a deteriorarsi economicamente, socialmente e culturalmente, crollando infine nel 476 d.C., Bisanzio, poi rinominata Costantinopoli, sopravvisse per quasi 1200 anni, e il solidus divenne la moneta più longeva e accettata della storia.

Il nome Bisanzio vuole quindi essere un omaggio alla saggezza di Costantino e celebrare l’unica moneta nella storia dell’umanità capace di durare oltre un millennio. Un esempio ed un auspicio per la Bitcoin, moneta di oro digitale che ci accompagnerà per un lunghissimo tempo.

\ Vedi anche: Monetazione bizantina su Wikipedia.

Il problema dei generali bizantini

Il termine Bitcoin soffre di un’ambiguità semantica: con lo stesso termine si indicano due cose ben diverse tra loro: il protocollo di comunicazione e la moneta digitale costruita su di esso. Bitcoin inteso come protocollo rappresenta la prima soluzione a un problema informatico, centrale per il funzionamento di sistemi distribuiti, denominato problema dei generali bizantini, formulato nel 1982 e che e’ rimasto irrisolto per decenni.

La sua formulazione è tipicamente la seguente:

Diverse divisioni dell’esercito bizantino, ciascuna guidata da un generale, sono accampate in posizioni strategiche attorno a una città nemica e dovono condividere una strategia di attacco coordinato per poter sopraffare il nemico. Le divisioni possono comunicare solo mediante messaggeri al fine di coordinare l’attacco decisivo. Il terreno impedisce alle divisioni bizantine di comunicare a distanza e queste possono comunicare solo tramite dei messaggeri. Come possono le varie divisioni accordarsi per un attacco congiunto sapendo che i messaggeri che inviano potrebbero essere catturati dal nemico, o che alcuni generali potrebbero addirittura tradire e mandare messaggeri con ordini sbagliati?

Il problema che devono risolvere i generali bizantini è lo stesso che affligge i sistemi di elaborazione distribuiti. Come raggiungere un consenso su una rete distribuita in cui alcuni nodi che la costituiscono possono essere difettosi o corrotti?

Il protocollo Bitcoin offre una soluzione a questo problema introducendo il concetto di “prova di lavoro” (proof of work) e della “catena di blocchi” (blockchain). E quindi, nuovamente, il nome Bisanzio si collega a Bitcoin ed alla principale innovazione tecnologica da esso introdotta.

Humanity's Natural State Is Chaos
Without order there is chaos. Humans competing with each other for scarce resources naturally leads to conflict until one group achieves significant power and instates a "monopoly on violence."

Power Brings Stability
Power has always been the key means to achieve stability in societies. Centralized power can be incredibly effective in addressing issues such as crime, poverty, and social unrest efficiently. Unfortunately this power is often abused and corrupted.

Centralized Power Breeds Tyranny
Centralized power often leads to tyrannical rule. When a select few individuals hold control over a society, they tend to become corrupted. Centralized power structures often lack accountability and transparency, and rely too heavily on trust.

Distributed Power Cultivates Freedom
New technology that empowers individuals provide us the ability to rebuild societies from the bottom up. Strong individuals that can defend and provide for themselves will help build strong local communities on a similar foundation. The result is power being distributed throughout society rather than held by a select few.

In the short term, relying on trust and centralized power is an easy answer to mitigating chaos, but freedom tech tools provide us the ability to build on top of much stronger distributed foundations that provide stability while also cultivating individual freedom.

The solution starts with us. Empower yourself. Empower others. A grassroots freedom tech movement scaling one person at a time.

ปี 1937 — บริษัท Hormel Foods Corporation ในเมืองออสติน รัฐมินนิโซตา สหรัฐฯ ชายคนหนึ่งชื่อ Jay C. Hormel ลูกชายของผู้ก่อตั้งบริษัท มีไอเดียแสนทะเยอทะยานว่า “อยากทำผลิตภัณฑ์จากหมู ที่เก็บได้นาน ไม่ต้องแช่เย็น และไม่แพง”

เพราะตอนนั้น หมูเหลือเยอะ โดยเฉพาะ “หัวไหล่หมู” ที่ขายไม่ออก เพราะมันไม่ใช่ชิ้นเนื้อพรีเมียมที่คนอยากซื้อไปทำอาหาร เจย์เลยทดลองบดเนื้อไหล่หมู เติมเกลือ น้ำตาล สารกันเสีย โซเดียมไนไตรต์ และสิ่งสำคัญสุดคือ เจลาตินจากน้ำต้มกระดูก เพื่อให้เนื้อเกาะตัว ไม่แห้ง และอยู่ได้นานโดยไม่ต้องแช่เย็น

ผลลัพธ์คือ หมูกระป๋อง 340 กรัมในกล่องสี่เหลี่ยม พร้อมเปิดฝาดึงด้วยมือ ไม่ต้องใช้ที่เปิดกระป๋อง ชูความ ราคาถูก เก็บง่าย พกพาสะดวก และไม่ต้องปรุงอะไรเพิ่มเติม ซ่อนความของเหลือเอาไว้เงียบๆ

และเพื่อให้คนจำได้ง่าย บริษัทจัดประกวดตั้งชื่อ และผู้ชนะเสนอคำว่า “Spam” = Spiced Ham (แต่ไม่มีใครรู้จริงๆ ว่าย่อจากอะไรแน่) แค่ “สั้น จัดจ้าน และจำง่าย” ก็พอ

เมื่อเกิดสงครามโลกครั้งที่ 2 ในปี 1939 สหรัฐฯ ยังไม่เข้าสงครามเต็มตัว แต่เริ่มเตรียมเสบียงสนับสนุนพันธมิตร และ Spam กลายเป็นของขวัญจากพระเจ้า เพราะ เก็บได้นานหลายปี ไม่ต้องแช่เย็น น้ำหนักเบา เปิดง่าย ไม่เสียง่ายแม้เจอฝุ่น โคลน หรือไอร้อนจากปืนใหญ่

รัฐบาลสหรัฐฯ เริ่มจัดสั่ง Spam ให้กับกองทัพในสัดส่วนที่มากขึ้นเรื่อยๆ โดยเฉพาะทหารแนวหน้าในยุโรปและแปซิฟิก เช่น ฮาวาย, ฟิลิปปินส์, กวม, และเกาหลี ระหว่างสงคราม Hormel ผลิต Spam มากถึง 15 ล้านกระป๋องต่อสัปดาห์ และส่งออกไปมากกว่า 100 ล้านกระป๋อง ภายในเวลาไม่กี่ปี

Jay C. Hormel ถือว่ามีบทบาททางสังคมและการเมืองอยู่ไม่น้อย โดยเฉพาะช่วงก่อนสงครามโลกครั้งที่ 2

เขาเคยเป็นสมาชิกของ America First Committee ซึ่งเป็นกลุ่มเคลื่อนไหวทางการเมืองที่มีอิทธิพลมากในช่วงก่อนสงครามโลกครั้งที่ 2 โดยกลุ่มนี้มีเป้าหมายคือ “ต่อต้านการที่อเมริกาจะเข้าไปร่วมสงครามในยุโรป” สมาชิกของกลุ่มนี้มีทั้งนักธุรกิจใหญ่ สื่อมวลชน นักวิชาการ รวมถึงชาร์ลส ลินด์เบิร์ก (นักบินชื่อดัง) เรียกได้ว่าเป็นกลุ่มที่มีอิทธิพลเชิงความคิดและการเมืองในช่วงปลายยุค 1930s

แม้ในตอนแรก Hormel จะมีแนวคิดไม่เห็นด้วยกับการเข้าสงคราม แต่พอสงครามเริ่มต้นจริง และสหรัฐฯ ต้องส่งทหารและเสบียงออกไปรบ เขาก็ “ปรับตัวทันที” และกลายเป็นหนึ่งในผู้จัดหาอาหารรายใหญ่ให้กองทัพ โดยเฉพาะ Spam ที่ผลิตส่งเป็นล้านกระป๋องต่อสัปดาห์ ซึ่งแน่นอนว่าไม่มีทางทำได้ถ้าไม่มีความสัมพันธ์และการประสานงานกับภาครัฐโดยตรง

หลังสงครามโลกสิ้นสุดในปี 1945 สิ่งที่รัฐบาลและภาคธุรกิจต้องเจอคือ จะทำยังไงกับโรงงานผลิตอาหารที่เคยทำเพื่อ “เลี้ยงทหารนับล้าน” แต่ตอนนี้ไม่มีสงครามแล้ว? Hormel ไม่ยอมให้ Spam หายไปจากโต๊ะอาหารโลกง่ายๆ แผนการตลาดที่ฉลาดมากของพวกเขาคือ 1. “Sell the nostalgia” ขายความทรงจำ! คนอเมริกันที่เป็นทหารผ่านศึก กลับมาใช้ชีวิตปกติ แต่ก็ยังคุ้นเคยกับ Spam อยู่แล้ว ก็ขายให้พวกเขานั่นแหละ 2. “ผูกกับอาหารเช้า” Hormel ทำสูตร “Spam and eggs” และโฆษณาว่าเป็นอาหารเช้าที่ให้พลังงาน ย่อยง่าย และเหมาะกับทุกครอบครัว 3. เจาะตลาดประเทศที่ได้รับ Spam ระหว่างสงคราม ฟิลิปปินส์, ฮาวาย, ญี่ปุ่น, เกาหลีใต้, อังกฤษ กลายเป็นตลาดหลัก บางประเทศพัฒนาเมนูท้องถิ่นกับ Spam เช่น ฟิลิปปินส์ Spam silog (Spam + ข้าว + ไข่ดาว), เกาหลี 부대찌개 (Budae-jjigae) หรือหม้อไฟทหาร, ญี่ปุ่น Spam onigiri, ฮาวาย Spam musubi (สแปมวางบนข้าว ปิดด้วยสาหร่าย) 4. สร้างแบรนด์ให้รัก Hormel สนับสนุนการจัดงานเทศกาล Spam (เช่น Spam Jam) และทำให้แบรนด์กลายเป็น Pop Culture ของอเมริกา เพื่อโปรโมตแบรนด์ให้เป็นของอเมริกันจ๋า ทั้งน่ารัก ทั้งเท่ ทั้งกินง่าย และกลายเป็นความภูมิใจของชนชั้นกลาง

ระหว่างปี 1937–1946 Spam สร้างชื่อให้ Hormel อย่างถล่มทลาย ถึงขั้นรัฐบาลโซเวียตยังเคยร้องขอให้สหรัฐฯ ส่ง Spam เข้าโซเวียตเพื่อเลี้ยงทหารแนวหน้า โดย นายพล Dwight D. Eisenhower (ต่อมาคือประธานาธิบดีสหรัฐฯ) เคยกล่าวว่า “I ate my share of Spam along with millions of other soldiers. I’ll even confess to a few unkind remarks about it—uttered during the strain of battle...

ในปี 1970s รายการตลกชื่อดังของอังกฤษอย่าง Monty Python’s Flying Circus ได้เอา Spam มาเล่นมุกในตอนหนึ่ง โดยฉากคือร้านอาหารที่ทุกเมนูมี Spam อยู่ในนั้น แล้วลูกค้าพยายามสั่งอาหารโดยไม่เอา Spam แต่ร้านไม่ยอม เพราะ “เมนูเรามี Spam ทุกอย่าง!” จนเสียงลูกค้ากับแม่ค้ากลายเป็นการโต้เถียงอันแสนตลก และมีนักแสดงแต่งเป็นไวกิ้งยืนร้อง “Spam, Spam, Spam, Spam...” ซ้ำๆ อยู่ด้านหลังแบบไม่รู้จบ https://youtu.be/anwy2MPT5RE?si=-68WQeng47lhJENJ

Only 1% of stablecoin transactions in 2024 are linked to criminal activity.

A recent report by TRM Labs has revealed new data on stablecoin usage in 2024. Contrary to widespread perception, 99% of stablecoin transactions were entirely legal and compliant with existing regulations.

The research shows that over 60% of last year’s total transaction volume was conducted using dollar-pegged tokens.

One key point highlighted in the report is the intrinsic traceability of stablecoins. Operating on public blockchains, these digital currencies allow for highly precise transaction monitoring through specialized analytics tools.

Issuers of centralized tokens like USDT and USDC also have the ability to freeze or permanently remove tokens associated with illicit activities.

TRM Labs data shows a 24% decrease in crypto-related criminal activity compared to 2023, with a total of $45 billion representing just 0.4% of overall crypto transaction volume. This decline is attributed to increased law enforcement efforts, stronger industry collaboration, and the growing adoption of advanced analytics tools.

According to TRM Labs, regulatory clarity provided by legislation such as the GENIUS Act could accelerate stablecoin adoption among major banks, financial institutions, and corporations. Many of these entities are already testing stablecoin-based infrastructures for cross-border payments, supply chain management, and programmable finance.

Bitcoin, desde a sua criação, tem sido um dos ativos mais debatidos no mundo financeiro, tanto pelos seus seguidores apaixonados quanto pelos céticos. A sua volatilidade extrema e o impacto que tem causado no sistema financeiro tradicional tornaram-no objeto de especulação constante. À medida que o tempo passa, a adoção de Bitcoin cresce e surgem novas discussões sobre o seu futuro, tanto no que diz respeito ao seu preço quanto à sua integração no sistema financeiro global. Neste contexto, existem várias previsões para o futuro de Bitcoin, com cenários tanto otimistas quanto cautelosos, baseados em fatores como regulamentação, adoção institucional e inovação tecnológica.

O preço de Bitcoin: previsões e fatores de influência

Adoção Institucional: A crescente adoção de Bitcoin por grandes empresas e investidores institucionais tem sido vista como um fator de valorização. Organizações como Tesla, MicroStrategy e Square já incorporaram Bitcoin nas suas reservas de tesouraria, o que gerou uma maior confiança no ativo como uma reserva de valor. À medida que mais empresas sigam esse caminho, a demanda por Bitcoin pode aumentar, pressionando o preço para cima.

Regulação Governamental: A forma como os governos lidam com Bitcoin é um dos maiores fatores de incerteza. Uma regulação excessiva pode restringir o acesso e diminuir o interesse, enquanto uma abordagem mais amigável pode impulsionar a adoção e aumentar o preço. Em países como El Salvador, que adotaram o Bitcoin como moeda legal, observa-se uma tendência positiva, mas em muitas outras nações, a regulação ainda é um grande desafio.

Oferta Limitada: A oferta de Bitcoin é limitada a 21 milhões de unidades, o que significa que não há risco de inflação ou aumento da quantidade disponível. Este facto torna Bitcoin particularmente atraente como reserva de valor, especialmente em tempos de incerteza económica global, o que pode continuar a impulsionar a sua valorização a longo prazo.

Tecnologia e Escalabilidade: Inovações como a Lightning Network e o Taproot, que visam melhorar a escalabilidade e a eficiência das transações, podem contribuir para uma adoção mais ampla, o que, por sua vez, poderia ter um impacto positivo no preço. Se Bitcoin se tornar mais acessível e viável para transações diárias, a sua utilidade será mais valorizada no mercado.

Adoção global do Bitcoin: o caminho para a inclusão financeira

A adoção global de Bitcoin está a crescer, especialmente em regiões onde os sistemas financeiros tradicionais são ineficazes ou limitados. Países com economias instáveis, como nações com alta inflação ou crise cambial, estão cada vez mais a ver no Bitcoin uma alternativa viável. Além disso, a inclusão financeira é um dos maiores motores dessa adoção, uma vez que Bitcoin pode oferecer serviços financeiros a populações que estão fora do alcance dos bancos tradicionais.

Mercados Emergentes: Em países como o Brasil, Argentina, Nigéria e outros mercados emergentes, a procura por Bitcoin tem crescido, pois as pessoas procuram proteger os seus ativos da desvalorização das suas moedas locais. Nesses locais, Bitcoin surge como uma alternativa de reserva de valor e meio de troca que não está sujeita ao controlo de uma autoridade central.

Adoção por Governos e Empresas: A crescente aceitação de Bitcoin por grandes empresas e governos pode acelerar a sua integração nas economias globais. Países como El Salvador demonstraram que é possível adotar Bitcoin como uma moeda oficial, enquanto grandes empresas estão cada vez mais a aceitar Bitcoin como forma de pagamento, o que legitima ainda mais o seu uso no comércio global.

Educação e Acessibilidade: A medida que mais pessoas compreendem o funcionamento do Bitcoin e as suas vantagens em termos de segurança, privacidade e liberdade financeira, a adoção tende a crescer. A simplicidade das plataformas de exchange e as melhorias em termos de usabilidade das carteiras digitais tornam mais fácil para os utilizadores entrarem no mercado e utilizarem Bitcoin no seu dia a dia.

Cenários futuros: otimismo ou cautela?

O futuro do Bitcoin é incerto, mas diversos cenários podem se desenrolar. O cenário otimista aponta para uma maior valorização e adoção global, impulsionada pela inovação tecnológica, aumento da confiança institucional e a busca por uma alternativa descentralizada ao sistema financeiro tradicional. Nesse cenário, Bitcoin poderia tornar-se uma forma amplamente aceite de pagamento e uma reserva de valor global, com preços que poderiam ultrapassar os valores mais elevados já registados.

Por outro lado, o cenário cauteloso sugere que os obstáculos como regulação governamental, competição com outras moedas digitais e possíveis falhas tecnológicas podem impedir que o Bitcoin se torne uma parte central do sistema financeiro. Além disso, a volatilidade do preço pode desencorajar aqueles que buscam estabilidade e segurança.

Resumindo, as previsões sobre o preço e a adoção global de Bitcoin são, sem dúvida, complexas e influenciadas por vários fatores. O futuro do Bitcoin dependerá de como a sociedade, os governos e as empresas responderão a essa nova forma de dinheiro. Embora o potencial de valorização seja significativo, o risco e a volatilidade são características que não podem ser ignoradas. À medida que a adoção global cresce e a tecnologia evolui, será necessário acompanhar de perto os desenvolvimentos que irão moldar o futuro de Bitcoin no sistema financeiro global.

"Privacy is necessary for an open society in the electronic age. Privacy is not secrecy.  A private matter is something one doesn't want the whole world to know, but a secret matter is something one doesn't want anybody to know. Privacy is the power to selectively reveal oneself to the world." - Eric Hughes, A Cypherpunk's Manifesto, 1993

---

Privacy is essential to freedom. Without privacy, individuals are unable to make choices free from surveillance and control. Lack of privacy leads to loss of autonomy. When individuals are constantly monitored it limits our ability to express ourselves and take risks. Any decisions we make can result in negative repercussions from those who surveil us. Without the freedom to make choices, individuals cannot truly be free.

Freedom is essential to acquiring and preserving wealth. When individuals are not free to make choices, restrictions and limitations prevent us from economic opportunities. If we are somehow able to acquire wealth in such an environment, lack of freedom can result in direct asset seizure by governments or other malicious entities. At scale, when freedom is compromised, it leads to widespread economic stagnation and poverty. Protecting freedom is essential to economic prosperity.

The connection between privacy, freedom, and wealth is critical. Without privacy, individuals lose the freedom to make choices free from surveillance and control. While lack of freedom prevents individuals from pursuing economic opportunities and makes wealth preservation nearly impossible. No Privacy? No Freedom. No Freedom? No Wealth.

Rights are not granted. They are taken and defended. Rights are often misunderstood as permission to do something by those holding power. However, if someone can give you something, they can inherently take it from you at will. People throughout history have necessarily fought for basic rights, including privacy and freedom. These rights were not given by those in power, but rather demanded and won through struggle. Even after these rights are won, they must be continually defended to ensure that they are not taken away. Rights are not granted - they are earned through struggle and defended through sacrifice.

Il progetto online Bisanz.io nasce dalla convinzione che Bitcoin sia un incredibile strumento di promozione e giustizia sociale, e nessuno che si dica riformista o progressista dovrebbe ignorare questo fatto. Un sito web in cui progressisti, riformisti, ambientalisti ed attivisti per la democrazia possano informarsi e discutere su com Bitcoin possa ridurre le disparità e le storture dell’attuale sistema finanziario.

L’urgenza di attivarsi affinché questa visione si diffonda nasce dal rischio concreto che si ripeta in Europa la stessa dinamica osservata negli Stati Uniti, dove questo tema fondamentale è stato lasciato nelle mani delle destre, da quelle liberali alle neo-con. La posizione del Partito Democratico USA su Bitcoin è infatti oggi ampiamente ostile, in maniera pregiudiziale e dettata principalmente da ragioni di posizionamento strategico.

In Italia Bitcoin è, al momento, semplicemente ignorato dalla politica. In Europa la situazione non è molto diversa da quella italiana con rare eccezioni.

Questa apatia della politica italiana ed europea nei confronti di Bitcoin può essere vinta mostrando quanto grande sia il potenziale di progresso sociale, equità e pace derivante dall'adozione di Bitcoin. Una opportunità che i progressisti europei dovrebbero cogliere, guidando l’analisi e il dibattito su questi temi.

Non si tratta naturalmente di inserire la parola “blockchain” nei contesti più assurdi (vedi i pomodori e le arance di Di Maio), ma di elaborare proposte unitarie di politica monetaria che includano una tecnologia (Bitcoin) rodata, democratica, globale, solidale.

Nel gruppo di amici che ha dato vita a Bisanz.io, c’è chi segue e studia con passione il tema Bitcoin dal lontano 2010, e chi invece ci si è avvicinato solo di recente. Cosa ci accomuna è la consapevolezza che questa innovazione ha il potenziale per risolvere le tante storture dell’attuale sistema finanziario. Una tecnologia che proteggendo i soggetti più deboli, può contribuire a ridurre le disparità, proteggere i risparmi, e stimolare gli investimenti.

Purtroppo, Bitcoin è ancora visto da tanti come uno strumento per criminali e speculatori, una percezione in gran parte giustificata da vicende legate non a Bitcoin, ma alle cosiddette criptovalute, e al più recente fenomeno dei token e degli NFT. Queste “innovazioni” nulla hanno a che spartire con la tecnologia e i valori di Bitcoin (decentralizzazione, trasparenza, open access, …) e le loro aberrazioni hanno alimentato la narrazione di cui sopra.

Più recentemente si è aggiunta la critica relativa all'impatto ambientale di Bitcoin, critica ancor più pretestuosa e in malafede. Chiunque dedichi un minimo di studio all'argomento potrà constatare come essa risulti infondata e che il mining di Bitcoin sia in realtà un prezioso alleato nella transizione alle energie rinnovabili. Queste ombre e la copertura mediatica negativa non hanno impedito all'ecosistema di Bitcoin di svilupparsi e crescere con costanza dal 2009 a oggi. Mentre centinaia di monete digitali alternative, nascevano e morivano guidate solo da logiche di profitto (o peggio), Bitcoin ha sempre tenuto la barra dritta sui valori fondanti, ampliato la base di utenti e le tipologie di utilizzo (esempio: pagamenti istantanei con Lightning Network).

La missione di Bisanzio è semplice: portare il nostro contributo affinché in Italia ed Europa maturino proposte per consentire a Bitcoin di esprimere tutto il suo potenziale democratico e di giustizia.

We are nearly at the point that if something interesting is posted on a centralized social platform it will usually be posted by someone to nostr.

We are nearly at the point that if something interesting is posted exclusively to nostr it is cross posted by someone to various centralized social platforms.

We are nearly at the point that you can recommend a cross platform app that users can install and easily onboard without additional guides or resources.

As companies continue to build walls around their centralized platforms nostr posts will be the easiest to cross reference and verify - as companies continue to censor their users nostr is the best censorship resistant alternative - gradually then suddenly nostr will become the standard. 🫡

The Dutch government recently implemented a new law regarding the recycling on tin cans that has monetized this form of trash. You can now hand in most coca cola, 7-up, or whatever brand tin at your local supermarket for 0.15 eurocent per piece.

This new incentive has people now opening up trashcans everywhere around the city and scavenging them for this monetary reward. Some guys are even using grapples and magnets to reach the hard to get cilinders. It appears that for some this has become their new job and they hand in full cart loads of this trash for the reward.

The receipts for this collection effort can only be exchanged for food, i.e. it is a discount on your grocery bill.

I wonder whether the best of them even exchange the receipts for a discount but to receive cash, as they've gone beyond their sustenance needs and require something more liquid. Or they might stack some kind of food item that maintains its value over time... who knows what this new economy is creating for interesting kinds of behavior.

There must be a limit to how much data is transferred across the bitcoin network in order to keep the ability to run and use your own node accessible. A node is required to interact with the global bitcoin network - if you do not use your own node then you must trust someone else's node. If nodes become inaccessible to run then the network will centralize around the remaining entities that operate them - threatening the censorship resistance at the core of bitcoin's value prop. The bitcoin protocol uses three main mechanisms to keep node operation costs low - a fixed limit on the amount of data in each block, an automatic difficulty adjustment that regulates how many blocks are produced based on current mining hash rate, and a robust dynamic transaction fee market.

Bitcoin transaction fees limit network abuse by making usage expensive. There is a cost to every transaction, set by a dynamic free market based on demand for scarce block space. It is an incredibly robust way to prevent spam without relying on centralized entities that can be corrupted or pressured.

After the 2017 bitcoin fee spike we had six years of relative quiet to build tools that would be robust in a sustained high fee market. Fortunately our tools are significantly better now but many still need improvement. Most of the pain points we see today will be mitigated.

The reality is we were never going to be fully prepared - pressure is needed to show the pain points and provide strong incentives to mitigate them.

It will be incredibly interesting to watch how projects adapt under pressure. Optimistic we see great innovation here.

Fold Holdings Secures $250 Million Equity Deal to Expand Bitcoin Treasury

Today, Fold Holdings, Inc. (NASDAQ: FLD), the first publicly traded bitcoin financial services company, has announced a $250 million equity purchase agreement to significantly increase its bitcoin holdings.

JUST IN: Publicly traded Fold secures $250 million equity facility to buy more #Bitcoin pic.twitter.com/M7E3fzwAsT

— Bitcoin Magazine (@BitcoinMagazine) June 17, 2025

Fold Holdings has the option, but not the obligation, to issue and sell up to $250 million in new common stock. The ability to access the funds is subject to certain conditions, including the requirement that a registration statement covering the resale of the stock be filed with and approved by the Securities and Exchange Commission (SEC).

“The Company is not required to use the Facility and controls the timing and amount of any drawdown on the Facility, subject to certain restrictions under the Facility,” said the press release. “The Company expects to use the net proceeds from the Facility, if any, primarily to acquire additional bitcoin for Fold’s corporate treasury.”

The shares offered under the facility will be issued through a private placement, relying on exemptions from the registration requirements of the Securities Act of 1933 and Regulation D. Fold noted that it “plans to file with the SEC a registration statement relating to the resale of the Common Stock issuable under the Facility.”

“The offers and sales of the Common Stock issuable under the Facility will be made in a private placement in reliance on an exemption from the registration requirements of the Securities Act of 1933,” according to the press release. “The Company cannot draw on the Facility, and the Common Stock may not be sold nor may offers to buy be accepted, prior to the time that the registration statement covering the resale of the Common Stock is declared effective by the SEC.”

On May 19, Fold also announced the launch of its Bitcoin gift card, marking its entry into the $300 billion U.S. retail gift card market. This new product allows consumers to purchase and gift bitcoin through familiar retail channels, with plans to expand to major retailers nationwide throughout the year.

“This gift card gives us distribution directly to millions of Americans who may not be buying Bitcoin because they haven’t downloaded a new app, don’t have a brokerage account, or haven’t seen the ETF,” said the Chairman and CEO of Fold Will Reeves.

“I think there’s a real chance by the end of 2025 that Bitcoin becomes the most popular gift in America because of this card,” stated Reeves.

Com a crescente digitalização do dinheiro, os governos de vários países começaram a desenvolver moedas digitais de banco central (CBDCs - Central Bank Digital Currencies) como resposta à popularização de Bitcoin. Enquanto Bitcoin representa um sistema financeiro descentralizado e resistente à censura, as CBDCs são versões digitais das moedas fiduciárias, controladas diretamente pelos bancos centrais. Essa concorrência pode moldar o futuro do dinheiro e definir o equilíbrio entre liberdade financeira e controlo estatal.

Diferenças fundamentais entre Bitcoin e CBDCs

Bitcoin e as CBDCs diferem em praticamente todos os aspetos fundamentais:

Centralização vs. Descentralização: Bitcoin opera numa rede descentralizada, onde nenhum governo ou entidade pode alterar as regras ou censurar transações. Já as CBDCs são emitidas e controladas pelos bancos centrais, permitindo um maior controlo sobre a circulação e utilização do dinheiro.

Oferta limitada vs. Inflação controlada: Bitcoin tem uma oferta fixa de 21 milhões de unidades, tornando-se um ativo escasso e deflacionário. As CBDCs, por outro lado, podem ser criadas sem limites, como acontece com as moedas fiduciárias tradicionais, sujeitas a políticas monetárias inflacionárias.

Privacidade vs. Monitorização: Bitcoin permite transações pseudónimas, garantindo um certo nível de privacidade financeira. As CBDCs, no entanto, podem ser programadas para permitir o rastreamento total de cada transação, facilitando a supervisão governamental e, potencialmente, o controlo sobre o que os cidadãos podem ou não gastar.

Resistência à censura vs. Controlo estatal: Bitcoin permite que qualquer pessoa realize transações sem depender de aprovação de terceiros. As CBDCs, por serem centralizadas, podem ser usadas pelos governos para restringir transações indesejadas ou mesmo confiscar fundos com um simples comando digital.

O que os governos pretendem com as CBDCs?

A introdução das CBDCs tem sido vendida com argumentos como:

Maior eficiência nas transações financeiras, eliminando intermediários e reduzindo custos bancários.

Facilidade na implementação de políticas económicas, como estímulos diretos à população ou tributação automatizada.

Combate a atividades ilegais, dado que as transações podem ser rastreadas em tempo real.

No entanto, muitas destas justificações levantam preocupações sobre a perda de privacidade financeira e o aumento do poder dos governos sobre o sistema monetário.

Bitcoin como alternativa às CBDCs

A ascensão das CBDCs pode fortalecer a posição de Bitcoin como alternativa de dinheiro verdadeiramente livre. À medida que os cidadãos percebem os riscos de um sistema financeiro 100% controlado pelo Estado, a procura por um ativo descentralizado e resistente à censura pode crescer.

Proteção contra o controlo estatal: Bitcoin permite que os utilizadores mantenham total soberania sobre o seu dinheiro, sem o risco de bloqueios arbitrários ou confiscações.

Preservação da privacidade financeira: Ao contrário das CBDCs, que podem monitorizar todas as transações, Bitcoin oferece um grau de anonimato que protege os indivíduos da vigilância excessiva.

Reserva de valor contra a inflação: Enquanto os governos podem emitir CBDCs indefinidamente, Bitcoin mantém a sua escassez garantida, tornando-se um refúgio contra políticas monetárias irresponsáveis.

Resumindo, a competição entre Bitcoin e as CBDCs será uma das maiores batalhas financeiras do futuro. Enquanto os governos tentam consolidar o seu controlo através de moedas digitais centralizadas, Bitcoin continua a ser a principal alternativa para aqueles que procuram independência financeira e proteção contra a vigilância estatal. A escolha entre um sistema financeiro livre e um sistema monitorizado e controlado poderá definir o rumo da economia digital nas próximas décadas.

The TENEX prompting system is a sophisticated, distributed architecture that enables AI agents to construct, process, and execute complex prompts with integrated tool support, context management, and conversation orchestration. Unlike traditional prompt systems that focus on single interactions, TENEX implements a multi-agent conversational framework with dynamic prompt building, real-time typing indicators, and sophisticated context preservation.

Architecture Overview

Core Design Philosophy

The TENEX prompting system follows a context-first, agent-centric approach where prompts are: - Dynamically constructed based on agent roles, project context, and available tools - Conversation-aware with signal-based state management - Tool-integrated with automatic prompt enhancement for available capabilities - Multi-agent orchestrated with team formation and collaborative prompt execution

Key Components

TENEX Prompting System Architecture ├── Agent Layer (tenex/src/agents/domain/) │ ├── Agent.ts - Core prompt building and response generation │ ├── TeamLead.ts - Enhanced prompts for orchestration │ └── Team.ts - Multi-agent conversation management ├── Orchestration Layer (tenex/src/agents/application/) │ ├── EventRouter.ts - Prompt routing and agent selection │ └── TeamOrchestrator.ts - Dynamic team formation prompts ├── Tool Integration (tenex/src/utils/agents/tools/) │ ├── ToolRegistry.ts - Dynamic tool prompt generation │ ├── ToolEnabledProvider.ts - Tool-enhanced prompt execution │ └── Individual Tools (readSpecs.ts, updateSpec.ts, etc.) ├── LLM Providers (tenex/src/llm/) │ ├── BaseLLMProvider.ts - Core prompt processing │ ├── AnthropicProvider.ts - Claude-specific prompt handling │ └── ToolEnabledProvider.ts - Tool-aware prompt execution └── Infrastructure ├── RulesManager.ts - Project rule integration ├── SpecCache.ts - Living documentation access └── LLMProviderAdapter.ts - Typing indicator integration

``typescript protected buildSystemPrompt(): string { let prompt =You are ${this.config.name}, ${this.config.role}.

Instructions: ${this.config.instructions} `;

// Add tool instructions if agent has tools
if (this.toolRegistry) {
    const toolPrompt = this.toolRegistry.generateSystemPrompt();
    if (toolPrompt) {
        prompt += `

${toolPrompt} `; } }

prompt += `

When responding, you should indicate the conversation state using one of these signals: - continue: You have more to say in this conversation phase - ready_for_transition: You've completed your part and are ready for the next phase - need_input: You need input from another team member - blocked: You're blocked and need help - complete: The entire task/conversation is complete

Bank run on every crypto bank then bank run on every "real" bank.

— ODELL (@ODELL) December 14, 2022

Good morning.

It looks like PacWest will fail today. It will be both the fifth largest bank failure in US history and the sixth major bank to fail this year. It will likely get purchased by one of the big four banks in a government orchestrated sale.  

March 8th - Silvergate Bank
March 10th - Silicon Valley Bank
March 12th - Signature Bank
March 19th - Credit Suisse
May 1st - First Republic Bank
May 4th - PacWest Bank?

PacWest is the first of many small regional banks that will go under this year. Most will get bought by the big four in gov orchestrated sales. This has been the playbook since 2008. Follow the incentives. Massive consolidation across the banking industry. PacWest gonna be a drop in the bucket compared to what comes next.

First, a hastened government led bank consolidation, then a public/private partnership with the remaining large banks to launch a surveilled and controlled digital currency network. We will be told it is more convenient. We will be told it is safer. We will be told it will prevent future bank runs. All of that is marketing bullshit. The goal is greater control of money. The ability to choose how we spend it and how we save it. If you control the money - you control the people that use it.

This article was originally published on dev.to by satshacker.

Alright, you’ve built a useful and beautiful website, tool or app. However, monetization isn’t a priority and you’d rather keep the project free, ads-free and accessible?

Accepting donations would be an option, but how? A PayPal button? Stripe? Buymeacoffe? Patreon?

All of these services require a bank account and KYC verification, before you can send and receive donations – not very convenient.

If we only could send value over the internet, with just one click and without the need of a bank account…

Oh, hold on, that’s bitcoin. The decentralized protocol to send value across the globe. Money over TCP/IP.

In this article, we’ll learn how anyone can easily add a payment button or donation widget on a website or app.

Let’s get into it.

Introduction

Bitcoin is digital money that you can send and receive without the need for banks. While bitcoin is extremely secure, it’s not very fast. The maximum transactions per second (TPS) the network can handle is about 7. Obviously that’s not useful for daily payments or microtransactions.

If you’d like to dig deeper into how bitcoin works, a great read is “Mastering Bitcoin” by Andreas Antonopoulos.

Bitcoin vs Lightning

If you’d like to receive bitcoin donations “on-chain” all you need is a bitcoin wallet. You simply display your bitcoin address on your site and that’s it. You can receive donations.

Instead of showing the actual bitcoin address, you can also turn it into a QR code.

However, this is not a recommended solution. Using static on-chain addresses has two major downsides. It lowers privacy for you and your donnors and it’s a UTXO disaster because many small incoming transactions could beocme hard to consolidate in the future.

For donations and small transactions, the Lightning Network is the better option. Lightning allows for instant settlement with fees only a fraction of a cent.

Similar to bitcoin, you have the choice between non-custodial and custodial wallets. This means, either you have full control over your money or the wallet provider has.

Option 1: Lightning Address

With the lightning address feature, you an easily receive donations to an email like address.

It looks like this: yourname@wallet.com

Many wallets support lightning addresses and make it easy to create one. Then, you simple add the address to your donation page and you’re ready to receive tips.

You can also add a link link as in lightning:yourname@wallet.com and compatible lightning wallets and browser wallets will detect the address.

Option 2: Lightning Donation Widgets

What is KYC/AML?

• The acronym stands for Know Your Customer / Anti Money Laundering.
• In practice it stands for the surveillance measures companies are often compelled to take against their customers by financial regulators.
• Methods differ but often include: Passport Scans, Driver License Uploads, Social Security Numbers, Home Address, Phone Number, Face Scans.
• Bitcoin companies will also store all withdrawal and deposit addresses which can then be used to track bitcoin transactions on the bitcoin block chain.
• This data is then stored and shared. Regulations often require companies to hold this information for a set number of years but in practice users should assume this data will be held indefinitely. Data is often stored insecurely, which results in frequent hacks and leaks.  
• KYC/AML data collection puts all honest users at risk of theft, extortion, and persecution while being ineffective at stopping crime. Criminals often use counterfeit, bought, or stolen credentials to get around the requirements. Criminals can buy "verified" accounts for as little as $200. Furthermore, billions of people are excluded from financial services as a result of KYC/AML requirements.

During the early days of bitcoin most services did not require this sensitive user data, but as adoption increased so did the surveillance measures. At this point, most large bitcoin companies are collecting and storing massive lists of bitcoiners, our sensitive personal information, and our transaction history.

Lists of Bitcoiners

KYC/AML policies are a direct attack on bitcoiners. Lists of bitcoiners and our transaction history will inevitably be used against us.

Once you are on a list with your bitcoin transaction history that record will always exist. Generally speaking, tracking bitcoin is based on probability analysis of ownership change. Surveillance firms use various heuristics to determine if you are sending bitcoin to yourself or if ownership is actually changing hands.  You can obtain better privacy going forward by using collaborative transactions such as coinjoin to break this probability analysis.

Fortunately, you can buy bitcoin without providing intimate personal information. Tools such as peach, hodlhodl, robosats, azteco and bisq help; mining is also a solid option: anyone can plug a miner into power and internet and earn bitcoin by mining privately.

You can also earn bitcoin by providing goods and/or services that can be purchased with bitcoin. Long term, circular economies will mitigate this threat: most people will not buy bitcoin - they will earn bitcoin - most people will not sell bitcoin - they will spend bitcoin.

There is no such thing as KYC or No KYC bitcoin, there are bitcoiners on lists and those that are not on lists.

So you want to Run Bitcoin…

1. Knots helps you exercise your self sovereignty verification muscle, instead of conforming to the TrustMeBro defaults of core. Thus, you are more prepared to actively defend Bitcoin in case of hardfork-softfork or other shenanigan’s.

2. Knots is more feature rich and useful than core, allowing end users to finely tune their nodes mempool policy to reject spam transactions from their own mempools, through such bitcoin.conf settings as: rejectparasites=1 , datacarrier=0, permitbaremultisig=0

3. Running a Underdog Bitcoin Client makes the Bitcoin network more robust as a whole. Supporting an ecosystem of multiple compatible clients running in tandem. Running knots makes Bitcoin, the network more robust, and makes the bitcoin development ecosystem richer. Knots is a backup-option in case core becomes obviously compromised. For decentralization, do we really want only a single implementation, with all our eggs in one basket with just bitcoin core? No.

4. Knots makes it so that you’re not using your node’s computing resources to hold and process spam shitcoin transactions and you have better control over what transactions you prioritize processing.” — Thus you can save your mempool resources from being abused by bad actors with Knots, but not with core, unfortunately. Core doesn’t believe in giving their end users too much choice. This has long been their attitude: to dictate down and deny non-consensus violating choice to end users.

5. Thus running Knots is a counter movement to the unfortunate attitude in core that has willfully neglected a core subset of it’s users who care about spam filters. Running Knots is not just a technical improvement in running Bitcoin. It’s a political statement in the Bitcoin development ecosystem.

So much for that tariff hyperinflation.\ \ New inflation numbers came at 1.2% — way below the Fed’s target.\ \ For the 4th time in Trump’s 4 months.\ \ Yet not a word about easing from the fed. Who’s now moving the inflation goal-posts to 2026 or even 2027. pic.twitter.com/nwzSCABrbR

— Peter St Onge, Ph.D. (@profstonge) June 16, 2025

After months of pundits, politicians, and partisan hacks kvetching about the aggressive tariff regime put forth by the Trump administration, we're beginning to see some data tickle in that makes it seem as if the tariff strategy may actually be working. At the end of last week, inflation data hit the market cooler than expected. Some core components coming in below the Federal Reserve's 2% inflation target. Granted, the CPI is manipulated and may be underreporting actual inflation. However, if we're simply comparing the CPI to itself, it seems to be moving in the right direction if, like me, you don't like when prices consistently rise month on month, year on year, decade on decade.

On top of this, the amount of revenue that tariffs are bringing in is significant and rising quickly. In May, tariff revenue collected in the U.S. hit a record of $22.3 billion. In April, the U.S. government brought in $16.5 billion from tariffs, and collectively, since Trump took office, the government has brought in around $67.2 billion in tariff revenue. Tariffs now reflect 4% of the total federal revenue, which is up from an average of 2% over the last few years. If this trend keeps up, the idea that tariffs can replace income tax revenue in the United States seems to be validated. Even better, it seems that the increased inflation that many were warning about hasn't materialized yet. There could be a way to increase the revenue of the federal government without increasing taxes on American producers while keeping prices lower. This is a beautiful thing.

I don't think it's time to ring the bell and claim victory in regards to tariffs and inflation quite yet, but this is extremely encouraging and something that all of you should be monitoring closely in the months ahead. Whether you're a Republican or a Democrat, I think we should all celebrate if the bold strategy of levying tariffs on the rest of the world to bring manufacturing home, while the government produces revenue via means that don't attack the income of individual citizens actually works out in the end.

It's crazy what pricing your life in Bitcoin does as you surf the internet. This newsletter was partly inspired by the video above from our good friend Peter St. Onge, but also because of this tweet I saw earlier today that priced the tariff revenue in bitcoin.

via The Kobeissi Letter

The Kobeissi Letter did not include the bitcoin denominations in its tweet. Our browser extension, Opportunity Cost, automatically injected it into the tweet so that I could understand how much revenue the government is bringing in in terms of Bitcoin. If they chose to use Bitcoin as a reserve asset.

It's crazy to think that at current bitcoin prices and if tariff revenue stays at the level it reached last month, the United States government could acquire a strategic reserve of 1 million bitcoin in less than five months. That really puts things into perspective, for me at least, about how much money is being thrown around the system both in the private markets and the public sector.

We are still extremely early in terms of bitcoin's adoption and monetization. Just looking at the tweet makes me want to tap somebody on the shoulder in the government and say, "Hey, look at this. If you sacrifice less than five months of tariff revenue and funnel that into bitcoin, you could have your strategic reserve by the end of the year. Before Thanksgiving even."

If tariff revenue continues to increase at the pace it has over the last couple of months, and the economy recovers, inflation isn't that bad, why not? Why not start building the strategic reserve with some of these revenues? A man can dream.

Washington's Bitcoin Awakening: From Crime Concerns to Strategic Asset

Ken Egan described a remarkable shift in how Washington views Bitcoin. Just a year ago, he recalls fighting defensive battles against basic misconceptions about criminal use and technical vulnerabilities. Today, policymakers ask sophisticated questions about Bitcoin's role in global monetary competition and national security strategy. Egan emphasized that discussions no longer waste time on "is it just for buying drugs" but instead focus on how Bitcoin can counter China's parallel financial systems and strengthen America's competitive position.

"There are people thinking, even the Department of Energy, some of whom will be at our conference, thinking really deeply about everything this ecosystem has to offer and how we can apply it to sort of a comprehensive national security strategy." - Ken Egan

Multiple government departments are now actively exploring Bitcoin's potential, Egan revealed. The Department of Defense examines mining for energy resilience, while the Department of Energy considers grid applications. Trump's executive order formally distinguished Bitcoin from other cryptocurrencies, signaling institutional recognition of its unique properties. This evolution from skepticism to strategic thinking represents a fundamental transformation in how America's policy establishment approaches Bitcoin.
