2025-05-28 22:02:26The former seems to have found solid product market fit. Expect significant volume, adoption, and usage going forward.
The latter's future remains to be seen. Dependence on Tor, which has had massive reliability issues, and lack of strong privacy guarantees put it at risk.

The Basics
- Lightning is a protocol that enables cheap and fast native bitcoin transactions.
- At the core of the protocol is the ability for bitcoin users to create a payment channel with another user.
- These payment channels enable users to make many bitcoin transactions between each other with only two on-chain bitcoin transactions: the channel open transaction and the channel close transaction.
- Essentially lightning is a protocol for interoperable batched bitcoin transactions.
- It is expected that on chain bitcoin transaction fees will increase with adoption and the ability to easily batch transactions will save users significant money.
- As these lightning transactions are processed, liquidity flows from one side of a channel to the other side, on chain transactions are signed by both parties but not broadcasted to update this balance.
- Lightning is designed to be trust minimized, either party in a payment channel can close the channel at any time and their bitcoin will be settled on chain without trusting the other party.
There is no 'Lightning Network'
- Many people refer to the aggregate of all lightning channels as 'The Lightning Network' but this is a false premise.
- There are many lightning channels between many different users and funds can flow across interconnected channels as long as there is a route through peers.
- If a lightning transaction requires multiple hops it will flow through multiple interconnected channels, adjusting the balance of all channels along the route, and paying lightning transaction fees that are set by each node on the route.
Example: You have a channel with Bob. Bob has a channel with Charlie. You can pay Charlie through your channel with Bob and Bob's channel with User C.
- As a result, it is not guaranteed that every lightning user can pay every other lightning user, they must have a route of interconnected channels between sender and receiver.
Lightning in Practice
- Lightning has already found product market fit and usage as an interconnected payment protocol between large professional custodians.
- They are able to easily manage channels and liquidity between each other without trust using this interoperable protocol.
- Lightning payments between large custodians are fast and easy. End users do not have to run their own node or manage their channels and liquidity. These payments rarely fail due to professional management of custodial nodes.
- The tradeoff is one inherent to custodians and other trusted third parties. Custodial wallets can steal funds and compromise user privacy.
Sovereign Lightning
- Trusted third parties are security holes.
- Users must run their own node and manage their own channels in order to use lightning without trusting a third party. This remains the single largest friction point for sovereign lightning usage: the mental burden of actively running a lightning node and associated liquidity management.
- Bitcoin development prioritizes node accessibility so cost to self host your own node is low but if a node is run at home or office, Tor or a VPN is recommended to mask your IP address: otherwise it is visible to the entire network and represents a privacy risk.
- This privacy risk is heightened due to the potential for certain governments to go after sovereign lightning users and compel them to shutdown their nodes. If their IP Address is exposed they are easier to target.
- Fortunately the tools to run and manage nodes continue to get easier but it is important to understand that this will always be a friction point when compared to custodial services.
The Potential Fracture of Lightning
- Any lightning user can choose which users are allowed to open channels with them.
- One potential is that professional custodians only peer with other professional custodians.
- We already see nodes like those run by CashApp only have channels open with other regulated counterparties. This could be due to performance goals, liability reduction, or regulatory pressure.
- Fortunately some of their peers are connected to non-regulated parties so payments to and from sovereign lightning users are still successfully processed by CashApp but this may not always be the case going forward.
Summary
- Many people refer to the aggregate of all lightning channels as 'The Lightning Network' but this is a false premise. There is no singular 'Lightning Network' but rather many payment channels between distinct peers, some connected with each other and some not.
- Lightning as an interoperable payment protocol between professional custodians seems to have found solid product market fit. Expect significant volume, adoption, and usage going forward.
- Lightning as a robust sovereign payment protocol has yet to be battle tested. Heavy reliance on Tor, which has had massive reliability issues, the friction of active liquidity management, significant on chain fee burden for small amounts, interactivity constraints on mobile, and lack of strong privacy guarantees put it at risk.
If you have never used lightning before, use this guide to get started on your phone.

Leaders Rally Behind BTC at Bitcoin 2025 Conference: Strategic Reserves, Market Clarity, and Legislative MomentumAt Bitcoin 2025, top U.S. lawmakers and Coinbase’s Chief Policy Officer discussed the U.S. government’s shifting tone on Bitcoin, strategic reserves, regulatory frameworks, and legislation—all pointing toward a bullish future for digital assets.
In a panel moderated by Grant McCarty, Co-President of the Bitcoin Policy Institute, the Bitcoin 2025 Conference saw a major spotlight on U.S. policy shifts surrounding digital assets. U.S. Representatives Byron Donalds and Bryan Steil were joined by Faryar Shirzad, Chief Policy Officer at Coinbase, to highlight what they described as a watershed moment for Bitcoin in Washington.
JUST IN:
US Congressman Byron Donalds says he's voting for the Strategic Bitcoin Reserve Act
"Bitcoin has proven to be a holder of value" pic.twitter.com/NuQlZ26Lmy
— Bitcoin Magazine (@BitcoinMagazine) May 27, 2025
“What the president and his team are doing is choosing to step into the digital assets marketplace,” said Byron Donalds. “Bitcoin is a key asset because it has demonstrated to be a holder of value outside of fiat currency and central banking.” Donalds emphasized that President Trump is taking the long view—strategically recognizing Bitcoin’s role in a national reserve capacity.
Bryan Steil pointed to Trump’s media magnetism and political leverage as the driver behind recent legislative momentum: “What he’s done is put a spotlight on the exact three bills… giving us the ability to drive forward.” He noted that legislation is difficult to pass, but with executive support, there’s newfound energy and opportunity to cross the finish line.
Shirzad echoed that sentiment: “The tone from the top point is exactly what Donald Trump has showed us… He wants a market structure built. He wants a much more strategic approach.” Coinbase, Shirzad added, sees the impact firsthand—legislators now recognize the need to support innovation rather than stifle it.
Donalds added: “If you talk to any business owner in the world, the number one thing they desire more than anything else is certainty and consistency.” That, he said, is what will turn Bitcoin into a trillion-dollar industry in the U.S., instead of one bogged down by regulatory ambiguity and legal overhead.
On the regulatory front, Steil noted: “Under the Biden administration, policy was being developed through enforcement actions. Bitcoin is decentralized and should be treated as a commodity.” Shirzad agreed, pushing for “regulatory therapy” to unleash billions still sidelined.
McCarty closed with mention of the Blockchain Regulatory Clarity Act—legislation that would protect open-source developers from rogue regulatory action: “It allows developers to operate without being punished.”
Donalds summed it up: “There’s only going to be 21 million ever in creation. That can’t be eroded by central banks. A strategic reserve for Bitcoin is critical in my opinion for the United States.”

2025-05-27 16:19:06Star Wars is often viewed as a myth of rebellion, freedom, and resistance to tyranny. The iconography—scrappy rebels, totalitarian stormtroopers, lone smugglers—suggests a deep anti-authoritarian ethos. Yet, beneath the surface, the narrative arc of Star Wars consistently affirms the necessity, even sanctity, of central authority. This blog entry introduces the question: Is Star Wars fundamentally a celebration of statism?
Rebellion as Restoration, Not Revolution
The Rebel Alliance’s mission is not to dismantle centralized power, but to restore the Galactic Republic—a bureaucratic, centrally governed institution. Characters like Mon Mothma and Bail Organa are high-ranking senators, not populist revolutionaries. The goal is to remove the corrupt Empire and reinstall a previous central authority, presumed to be just.
- Rebels are loyalists to a prior state structure.
- Power is not questioned, only who wields it.
Jedi as Centralized Moral Elites
The Jedi, often idealized as protectors of peace, are unelected, extra-legal enforcers of moral and military order. Their authority stems from esoteric metaphysical abilities rather than democratic legitimacy.
- They answer only to their internal Council.
- They are deployed by the Senate, but act independently of civil law.
- Their collapse is depicted as tragic not because they were unaccountable, but because they were betrayed.
This positions them as a theocratic elite, not spiritual anarchists.
Chaos and the Frontier: The Case of the Cantina
The Mos Eisley cantina, often viewed as a symbol of frontier freedom, reveals something darker. It is: - Lawless - Violent - Culturally fragmented
Conflict resolution occurs through murder, not mediation. Obi-Wan slices off a limb; Han shoots first—both without legal consequence. There is no evidence of property rights, dispute resolution, or voluntary order.
This is not libertarian pluralism—it’s moral entropy. The message: without centralized governance, barbarism reigns.
The Mythic Arc: Restoration of the Just State
Every trilogy in the saga returns to a single theme: the fall and redemption of legitimate authority.
- Prequels: Republic collapses into tyranny.
- Originals: Rebels fight to restore legitimate order.
- Sequels: Weak governance leads to resurgence of authoritarianism; heroes must reestablish moral centralism.
The story is not anti-state—it’s anti-bad state. The solution is never decentralization; it’s the return of the right ruler or order.
Conclusion: The Hidden Statism of a Rebel Myth
Star Wars wears the costume of rebellion, but tells the story of centralized salvation. It: - Validates elite moral authority (Jedi) - Romanticizes restoration of fallen governments (Republic) - Portrays decentralized zones as corrupt and savage (outer rim worlds)
It is not an anarchist parable, nor a libertarian fable. It is a statist mythology, clothed in the spectacle of rebellion. Its core message is not that power should be abolished, but that power belongs to the virtuous few.
Question to Consider:
If the Star Wars universe consistently affirms the need for centralized moral and political authority, should we continue to see it as a myth of freedom? Or is it time to recognize it as a narrative of benevolent empire? -

2025-05-21 16:58:36The other day, I had the privilege of sitting down with one of my favorite living artists. Our conversation was so captivating that I felt compelled to share it. I’m leaving his name out for privacy.
Since our last meeting, I’d watched a documentary about his life, one he’d helped create. I told him how much I admired his openness in it. There’s something strange about knowing intimate details of someone’s life when they know so little about yours—it’s almost like I knew him too well for the kind of relationship we have.
He paused, then said quietly, with a shy grin, that watching the documentary made him realize how “odd and eccentric” he is. I laughed and told him he’s probably the sanest person I know. Because he’s lived fully, chasing love, passion, and purpose with hardly any regrets. He’s truly lived.
Today, I turn 44, and I’ll admit I’m a bit eccentric myself. I think I came into the world this way. I’ve made mistakes along the way, but I carry few regrets. Every misstep taught me something. And as I age, I’m not interested in blending in with the world—I’ll probably just lean further into my own brand of “weird.” I want to live life to the brim. The older I get, the more I see that the “normal” folks often seem less grounded than the eccentric artists who dare to live boldly. Life’s too short to just exist, actually live.
I’m not saying to be strange just for the sake of it. But I’ve seen what the crowd celebrates, and I’m not impressed. Forge your own path, even if it feels lonely or unpopular at times.
It’s easy to scroll through the news and feel discouraged. But actually, this is one of the most incredible times to be alive! I wake up every day grateful to be here, now. The future is bursting with possibility—I can feel it.
So, to my fellow weirdos on nostr: stay bold. Keep dreaming, keep pushing, no matter what’s trending. Stay wild enough to believe in a free internet for all. Freedom is radical—hold it tight. Live with the soul of an artist and the grit of a fighter. Thanks for inspiring me and so many others to keep hoping. Thank you all for making the last year of my life so special.

2025-05-27 09:21:37After 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!

US Senator Cynthia Lummis Discusses Bitcoin Reserve, Stablecoin Legislation, and Market Structure Bill at Bitcoin 2025 ConferenceAt the 2025 Bitcoin Conference in Las Vegas, U.S Senator Cynthia Lummis and CLO of Coinbase Paul Grewal discussed the market structure bill, stablecoin bill, future taxing system, bitcoin strategy reserve and bitcoin mining.
Cynthia Lummis started by commenting about the market structure bill and stablecoin bill.
“The market structure bills is probably more important to a lot of the people in this conference than the stablecoin bill because there are a lot of businesses, yours among them,” said Lummis. “There are businesses for people who either buy and hold, so they want a custodial service or there are companies that lend Bitcoin, there is a futures market for Bitcoin, there are so many ways in which Bitcoin can interface with fiat currency with the US dollar.”
Lummis also mentioned the tax system that she wants to implement and what her office has submitted to the finance committee.
“As the lighting network develops and companies like Strike sort of have been leaders in that space,” added Lummis. “Create an opportunity for transactions to occur on a daily basis in Bitcoin. Everything from buying a cup of coffee to dinner somewhere. It would be helpful that certain transactions of that size below 600 dollars per transaction, not be subject to taxation.”
During her speech, she went into detail on one the biggest problems lawmakers are facing against digital assets.
“Part of the problem in the last four years has been largely regulatory agencies that have been very hostile towards digital assets, so we are trying to change as fast as we can,” said Lummis. “It doesn’t happen overnight. We don’t even have a confirmed IRS director in place yet, so it is really hard to get these structural changes enacted by the rule makers at the IRS when there is no IRS commission yet in place.”
Ending the panel, Lummis addressed one of the biggest reasons the US government should get into Bitcoin.
“We are 37 trillion dollars in debt, so if we bought and held a million Bitcoin for 20 years it will cut that debt in half and we have underperforming assets that can be converted to Bitcoin without borrowing additional money. Bitcoin is such an important Global Strategic asset and it is not only important in the economy, but in our global defense because there are components to our defense. One is having a lethal war fighting machine that can overcome other armies, another military effort. Another one is having an economic machine that can overcome other currencies.” She continued, “Even our military generals say that bitcoin is an important deterrent to aggression from other countries, especially from China.”

2025-05-28 20:37:58Bitcoin: Peer-to-peer sistem elektronskog novca
Satoshi Nakamoto
satoshin@gmx.com
Prevedeno na srpski sa bitcoin.org/bitcoin.pdf od strane ECD
Sažetak. Potpuna peer-to-peer verzija elektronskog novca omogućila bi slanje uplata putem interneta direktno od jedne strane ka drugoj bez posredovanja finansijskih institucija. Digitalni potpisi pružaju deo rešenja, ali se glavni benefiti gube ako je i dalje potrebna pouzdana treća strana za sprečavanje dvostruke potrošnje. Predlažemo rešenje problema dvostruke potrošnje korišćenjem peer-to-peer mreže. Mreža vremenski označava transakcije tako što ih hešuje u tekući lanac dokaza o radu (proof of work) temeljen na hešu, formirajući zapis koji se ne može promeniti bez ponovnog rada i objavljivanja dokaza o tom radu. Najduži lanac ne služi samo kao dokaz niza događaja, nego i kao dokaz da je taj niz događaja potvrđen od strane dela peer-to-peer mreže koja poseduju najveću zbirnu procesorsku snagu (CPU). Sve dok većinu procesorske snage kontrolišu čvorovi (nodes) koji ne sarađuju u napadu na mrežu, oni će generisati najduži lanac i nadmašiti napadače. Sama mreža zahteva minimalnu strukturu. Poruke kroz mrežu se prenose uz pretpostavku da svaki čvor čini maksimalan napor da poruku prenese u svom izvornom obliku i na optimalan način, a čvorovi mogu napustiti mrežu i ponovo joj se pridružiti po želji, prihvatajući najduži lanac dokaza o radu kao dokaz onoga što se dogodilo dok ih nije bilo.
1. Uvod
Trgovina na Internetu počela je da se oslanja skoro isključivo na finansijske institucije koje služe kao pouzdani posrednici pri obradi elektronskih plaćanja. Iako sistem radi dovoljno dobro za većinu transakcija i dalje trpi od inherentnih slabosti modela utemeljenog na poverenju.
Potpuno nepovratne transakcije zapravo nisu moguće, jer finansijske institucije ne mogu izbeći posredovanje u rešavanju eventualnih sporova. Troškovi posredovanja povećavaju troškove transakcija, ograničavaju minimalnu praktičnu veličinu transakcija i onemogućuju male, povremene transakcije jer postoji velika šteta zbog gubitka mogućnosti da se izvrše nepovratna plaćanja za nepovratne usluge. Uz mogućnost povraćaja transakcije, potreba za poverenjem raste. Trgovci moraju biti oprezni prema svojim kupcima i tražiti im više informacija nego što bi inače bilo neophodno. Određeni procenat prevara prihvaćen je kao neizbežan. Ovi troškovi i nepouzdanost plaćanja mogu se izbeći korišćenjem gotovine, ali ne postoji mehanizam za elektronsko plaćanje bez pouzdane treće strane.
Ono što je potrebno je elektronski sistem plaćanja zasnovan na kriptografskom dokazu umesto na poverenju, koji omogućava da bilo koje dve strane direktno i dobrovoljno međusobno trguju bez potrebe za posrednikom. Transakcije koje su nepovratne bi zaštitile prodavce od prevara, a escrow mehanizmi mogli bi se lako implementirati radi zaštite kupaca. U ovom dokumentu predlažemo rešenje problema dvostruke potrošnje korišćenjem peer-to-peer distribuiranog servera vremenskih oznaka (timestamp) za generisanje računarskog dokaza o hronološkom redosledu transakcija. Sistem je siguran sve dok pošteni čvorovi zajedno kontrolišu više procesorske snage procesora nego bilo koja udružena grupa napadačkih čvorova.
2. Transakcije
Elektronski novčić definišemo kao lanac digitalnih potpisa. Svaki vlasnik prenosi novčić na sledećeg digitalnim potpisivanjem heša prethodne transakcije i javnog ključa sledećeg vlasnika, dodajući ih potom na kraj novčića. Primalac transakcije može da verifikuje potpise, a time i lanac vlasništva.
Problem je naravno u tome što primalac ne može potvrditi da jedan od prethodnih vlasnika nije dva puta poslao isti novčić. Uobičajeno rešenje je uvođenje pouzdanog centralizovanog posrednika, kreatora novčića koji proverava sve transakcije. Nakon svake transakcije, novčić se mora vratiti kreatoru kako bi se izdao novi novčić i veruje se da samo za novčiće izdate direktno od kreatora možemo biti sigurni da nisu dva puta potrošeni. Problem sa ovim rešenjem je što sudbina čitavog novčanog sistema zavisi od kompanije koja kreira novčiće, jer svaka transakcija mora da prođe kroz nju, baš kao što je slučaj sa bankom.
Treba nam način da primalac bude siguran da prethodni vlasnici nisu potpisali nikakve ranije transakcije kojim bi potrošili taj novčić. Za naše potrebe, računamo transakciju koja se prva desila i ne zanimaju nas naredni pokušaji da se isti novčić ponovo pošalje. Jedini način da sa sigurnošću potvrdimo da taj novčić nije prethodno bio poslat je da imamo informacije o svim transakcijama koje su se ikada desile. U modelu baziranom na centalizovan kreatoru, taj kreator je imao informacije o svim transakcijama i odlučivao koja transakcija je prva stigla. Da bismo to postigli bez pouzdanog posrednika, transakcije moraju biti javno objavljene [1] i potreban nam je sistem u kojem učesnici mogu da se dogovore o jedinstvenoj istoriji redosleda kojim su transakcije primljene. Primaocu je potreban dokaz da se u trenutku dešavanja svake od transakcija većina čvorova složila oko toga da je baš ta transakcija bila ona koja je prva primljena.
3. Server vremenskih oznaka
Rešenje koje predlažemo počinje serverom vremenskih oznaka. Server vremenske oznake radi tako što uzima heš bloka podataka kojem će se dodeliti vremenska oznaka i objavi taj heš svima u mreži, slično kao u novinama ili kao post na Usenet mreži [2-5]. Vremenska oznaka očigledno dokazuje da su podaci morali postojati u to vreme kako bi ušli u haš. Svaka vremenska oznaka sadrži prethodnu vremensku oznaku u svom hešu, formirajući tako lanac, pri čemu svaka dodatna vremenska oznaka pojačava potvrde onih pre nje.
4. Dokaz o radu (Proof-of-Work)
Da bismo implementirali distribuirani server vremenskih oznaka na peer-to-peer principu, moraćemo da koristimo sistem dokaza o radu sličan Hashcash-u Adama Back-a [6], umesto Uneset postova ili novinskih objava. Dokaz o radu uključuje traženje vrednosti koja će, kada se hešuje, na primer pomoću SHA-256 heš funkcije, stvarati heš čiji binarni zapis započinje određenim brojem nula. Prosečna količina potrebnog rada eksponencijalno raste sa brojem potrebnih početnih nula, a može se proveriti izvršavanjem samo jedne heš fuknkcije.
Za našu mrežu vremenskih oznaka implementiramo dokaz o radu povećavajući nonce broja u bloku sve dok se ne pronađe ona vrednost nonce-a koja daje hešu bloka potreban broj početnih nula. Jednom kada se procesorska snaga utroši kako bi se zadovoljio dokaz o radu, blok se ne može izmeniti bez ponovljenog rada. Kako se kasniji blokovi vežu na taj blok, rad potreban da se on izmeni uključivao bi i ponovno obrađivanje svih blokova nakon njega.
Dokaz o radu takođe rešava problem utvrđivanja većine pri odlučivanju. Ako bi se većina zasnivala na principu jednog glasa po IP adresi, mogao bi je narušiti svako ko je u stanju da glasa sa više IP adresa odjednom. Dokaz o radu u osnovi predstavlja jedan glas po jedinici procesorske snage. Većinska odluka je predstavljena najdužim lancem u čije je stvaranje zapravo investirano najviše rada prilikom dokazivanja. Ako većinu procesorske snage kontrolišu pošteni čvorovi, pošten lanac će rasti najbrže i nadmašiće sve konkurentske lance. Da bi izmenio neki od prethodnih blokova, napadač bi morao da ponovi dokaz o radu za taj blok i sve blokove nakon njega, a zatim da sustigne i nadmaši količinu rada poštenih čvorova. Kasnije ćemo pokazati da se dodavanjem novih blokova eksponencijalno smanjuje verovatnoća da će sporiji napadač uspeti da sustigne pošteni lanac.
Da bi se kompenzovalo povećanje brzine hardvera i promenljivo interesovanje ljudi za vođenje čvorova tokom vremena, težina obavljanja dokaza o radu (proof-of-work difficulty) određuje se prema prosečnom broju blokova krairanih za sat vremena. Ako se blokovi stvaraju prebrzo, težina se povećava.
5. Mreža
Koraci za vođenje mreže su sledeći:
1) Nove transakcije se prosleđuju svim čvorovima u mreži. 2) Svaki čvor prikuplja nove transakcije u blok. 3) Svaki čvor radi na pronalaženju dokaza o radu dovoljnog nivoa težine za svoj blok. 4) Kada čvor pronađe dokaz o radu, on emituje taj blok ka svim čvorovima. 5) Čvorovi prihvataju blok samo ako su sve transakcije u njemu ispravne i nisu već potrošene. 6) Čvorovi izražavaju prihvatanje bloka radeći na stvaranju sledećeg bloka u lancu, koristeći heš prihvaćenog bloka kao prethodni heš.
Čvorovi uvek smatraju da je najduži lanac ispravan i nastaviće da rade na njegovom produžavanju. Ako dva čvora istovremeno emituju različite verzije sledećeg bloka, neki čvorovi prvo mogu primiti jedan ili drugi blok. U tom slučaju svaki čvor radi na prvom koji je dobio, ali čuvaju drugu kariku lanca u slučaju da ona postane duža. Dilema će biti rešena kada se pronađe sledeći dokaz o radu i jedna karika postane duža; čvorovi koji su radili na drugoj karici lanca će se prebaciti na dužu kariku.
Emitovanje novih transakcija ne mora nužno doći do svih čvorova. Sve dok stižu do velikog broja čvorova, te transakcije će ući u blok. Slično važi i za blokove, ni oni ne moraju doći odmah do svih čvorova. Ako neki čvor propusti da primi informaciju o bloku, kada mu stigne sledeći blok,primetiće da je propustio jedan, pa će ga tražiti naknadno.
6. Podsticaj
Po pravilu, prva transakcija u bloku je posebna transakcija koja kreira novi novčić u vlasništvu kreatora bloka. Ovo daje podsticaj čvorovima da podrže mrežu i pruža način za početnu ubacivanje novčića u opticaj, budući da ne postoji centralno telo koje ih izdaje. Stalno dodavanje konstantne količine novih novčića liči na rudarenje zlata, gde rudari ulažu resurse kako bi izrudarili nove količine zlata i ubacili ih u opticaj. U našem slučaju ulaže se procesorsko vreme i električna energija.
Podsticaj se takođe može finansirati i transakcionim naknadama. Ako je iznos izlaznog dela transakcije manji od ulaznog, razliku čini naknada za transakciju koja se dodaje iznosu nagrade za kreatora bloka koji sadrži tu transakciju. Nakon što predefinisani broj novčića uđe u opticaj, podsticaj mogu u potpunosti činiti transakcione naknade, čime se sistem oslobađa inflacije.
Čvorovi su na ovaj način podstaknuti da ostanu pošteni. Ako je pohlepni napadač u stanju da angažuje više procesorske snage od svih poštenih čvorova zajedno, morao bi da bira između toga da poništi svoje izvršene transakcije i time prevari ljude ili da procesorsku snagu koristi za stvaranje novih novčića. On bi trebalo bi uvidi da je isplativije igrati po pravilima koja ga nagrađuju sa više novih novčića od svi drugi zajedno, nego da potkopava sistem i vrednost sopstvenog bogatstva.
7. Oslobađanje prostora na hard disku
Kada je dovoljno blokova dodato nakon poslednje transakcije novčića, prethodne transakcije tog novčića se mogu odbaciti kako bi se uštedeo prostor na hard disku. Kako bi se to ostvarilo bez razbijanja heša bloka, transakcije su hešovane u Merkleovo stablo (Merkle Tree) [7] [2] [5], gde je samo koren uključen u heš bloka. Stari blokovi se tada mogu sabiti uklanjanjem nepotrebnih grana drveta. Unutrašnji heševi ne moraju biti skladišteni.
Zaglavlje bloka bez transakcija bilo bi oko 80 bajtova. Ako pretpostavimo da su blokovi generisani svakih 10 minuta, 80 bajtova * 6 * 24 * 365 = 4,2 MB godišnje. Imajući u vidu činjenicu da se u 2008. godini računari uglavnom prodaju sa oko 2 GB RAM-a i Murov zakon koji predviđa trenutni rast od 1,2 GB godišnje, skladištenje ne bi trebalo da predstavlja problem čak i ako se zaglavlja bloka moraju čuvati u memoriji.
8. Pojednostavljena verifikacija plaćanja
Moguće je verifikovati plaćanja bez vođenja čitavog mrežnog čvora. Korisnik samo treba da sačuva kopiju zaglavlja blokova najdužeg lanca dokaza o radu, do koje može doći upitom ka mrežnim čvorovima dok se ne uveri da je dobio najduži lanac i dobije Merkleova granu
koja povezuje transakciju sa blokom u koji je uneta vremenska oznaka za tu transakciju. Ne može samostalno proveriti transakciju, ali povezujući je sa mestom u lancu može videti da je prihvaćena od strane čvora mreže i da su na njen blok dodati naknadni blokovi što dalje potvrđuje da ju je mreža prihvatila.
Kao takva, verifikacija je pouzdana sve dok pošteni čvorovi kontrolišu mrežu, ali je ranjiva ako napadač nadjača ostatak mreže. Čvorovi mreže mogu sami proveriti transakcije, ali napadačeve lažne transakcije mogu zavarati one koji koriste pojednostavljenu metodu verifikacije transakcija sve dok je on u stanju da nadjačava ostatak mreže. Jedna od strategija zaštite bila bi prihvatanje upozorenja čvorova mreže kada otkriju nevažeći blok, pri čemu bi korisnikov softver morao da preuzme ceo blok i sporne transakcije kako bi potvrdio nepravilnost. Biznisi koji primaju česte uplate će verovatno želeti da pokrenu i vode sopstvene čvorove radi brže verifikacije i potrebe da im sigurnost ne zavisi od drugih.
9. Kombinovanje i deljenje vrednosti
Iako bi bilo moguće pojedinačno rukovati novčićima, bilo bi nezgrapno kreirati zasebnu transakciju za svaki cent u toj transferu. Da biste dozvolili podelu i kombinovanje vrednosti, transakcije sadrže više ulaza i izlaza. Obično će postojati ili jedan ulaz iz veće prethodne transakcije ili više unosa koji kombinuju manje iznose, a najviše dva izlaza: jedan za samo plaćanje, a jedan koji vraća kusur, ako ga ima, nazad pošiljaocu.
Treba napomenuti da situacija u kojoj transakcija zavisi od nekoliko drugih transakcija, a te transakcije zavise od još mnogo više, ovde nije problem. Nikada ne postoji potreba za izdvajanjem istorije pojedinačne transakcije.
10. Privatnost
Tradicionalni bankarski model postiže odgovarajući nivo privatnosti ograničavanjem pristupa informacijama na strane uključene u transakciju i posrednika. Neophodnost javnog objavljivanja svih transakcija isključuje mogućnost primene pomenutog modela, ali privatnost se i dalje može zadržati na drugi način: čuvanjem javnih ključeva (public keys) anonimnim. Javnost može videti da neko šalje iznos nekom drugom, ali bez informacija koje povezuju transakciju sa bilo kim. Ovo je slično količini informacija koje objavljuju berze, gde se vreme i veličina pojedinačnih trgovina čine javnim, ali bez navođenja ko su stranke uključene u tu trgovinu.
Kao dodatni zaštitni zid, preporučljivo je koristiti novi par ključeva za svaku transakciju, kako ne bi bili povezane sa zajedničkim vlasnikom. Neka povezivanja su i dalje neizbežna kod transakcija sa više ulaza, koje nužno otkrivaju da su njihovi ulazi bili u vlasništvu istog vlasnika. Rizik je taj da bi se otkrivanjem vlasnik ključa mogle otkriti i ostale transakcije koje su pripadale tom vlasniku.
11. Proračuni
Razmatramo scenario u kome napadač pokušava da generiše alternativni lanac brže od poštenog lanca. Čak i ako se to postigne, to ne omogućuje proizvoljne promene u sistemu, poput stvaranje vrednosti ni iz čega ili uzimanje novca koji nikada nije pripadao napadaču. Pošteni čvorovi neće prihvatiti nevažeće transakcije kao uplatu i nikada neće prihvatiti blok koji ih sadrži. Napadač može samo pokušati da promeni jednu od svojih transakcija kako bi vratio novac koji je nedavno potrošio.
Trka između poštenog lanca i lanca napadača može se predstaviti kao binomska distribucija slučajne diskretne varijable (Binomial Random Walk). Uspešni ishod je da se pošten lanac produži za jedan blok, povećavajući svoje vođstvo za +1, a neuspešni ishod je da se napadačev lanac produži za jedan blok, smanjujući zaostatak za -1.
Verovatnoću da napadač nadoknadi određeni deficit možemo izraziti kroz problem kockareve propasti (Gambler’s Ruin Problem). Pretpostavimo da kockar sa neograničenim iznosom novca počinje sa zaostatkom i igra potencijalno beskonačan broj ponovljenih igara u pokušaju da nadoknadi zaostatak. Možemo izračunati verovatnoću za nadoknađivanje zaostatka ili da će napadač stići pošten lanac, na sledeći način [8]:
p= verovatnoća da pošten čvor pronađe sledeći blok q= verovatnoća da napadač pronađe sledeći blok qz= verovatnoća da će napadač ikada dostići z blokova zaostatka
S obzirom na našu pretpostavku da je p > q, verovatnoća pada eksponencijalno kako se povećava broj blokova koje napadač mora da nadoknadi. Sa šansama protiv njega, ako mu se u početku ne posreći, njegove šanse postaju manje i manje sa povećanjem zaostatka.
Sada razmatramo koliko primalac nove transakcije treba da čeka pre nego što postane
dovoljno siguran da pošiljalac ne može promeniti transakciju. Pretpostavljamo da je pošiljalac napadač koji želi da natera primaoca da veruje da mu je platio, a zatim nakon nekog vremena tu transakciju preusmeri ka sebi. Primalac će primetiti kada se to dogodi, ali pošiljalac se nada da će tad već biti prekasno.
Primalac generiše novi par ključeva i daje javni ključ pošiljaocu neposredno pre potpisivanja transakcije. Ovo sprečava pošiljaoca da unapred pripremi lanac blokova radeći na njemu neprekidno dok mu se ne posreći da stekne dovoljnu prednost i u tom trenutku izvrši transakciju. Kada se transakcija pošalje, nepošteni pošiljalac počinje tajno da radi na paralelnom lancu koji sadrži alternativnu verziju njegove transakcije.
Primalac čeka dok transakcija ne bude dodata u blok, i dok z blokova nije dodato nakon tog bloka. On ne zna tačno koliko je napadač napredovao, ali pod pretpostavkom da su pošteni blokovi kreirani očekivanom dinamikom, potencijalni napredak napadača će biti prikazan kao Poasonova distribucija sa očekivanom vrednošću:
Kako bismo izračunali verovatnoću da napadač ipak može da nadoknadi zaostatak, množimo gustinu verovatnoće za svaki nivo napretka koji je mogao da ostvari sa verovatnoćom da od tog trenutka može da potpuno nadoknadi zaostatak:
Preuređujemo formulu kako bismo izbegli sabiranje beskonačnog broja sabiraka zbog repa distribucije:
I konvertujemo u programski kod u programskom jeziku C…
Kroz par primera, vidimo da verovatnoća opada eksponencijalno sa porastom z.
Rešavanje za P < 0.1%…
12. Zaključak
Predložili smo sistem za elektronske transakcije bez oslanjanja na poverenje. Počeli smo sa uobičajenim šablonom i novčićima nastalim iz digitalnih potpisa, koji pruža snažnu kontrolu nad vlasništvom, ali je nepotpun bez načina da se spreči dvostruka potrošnja. Kako bismo ovo rešili, predložili smo peer-to-peer mrežu koja koristi dokaz o radu za čuvanje javne istorije transakcija čija izmena napadačima brzo postaje računski nepraktična ako pošteni čvorovi kontrolišu većinu procesorske snage. Mreža je robusna u svojoj nestrukturiranoj jednostavnosti. Svi čvorovi rade istovremeno uz malo koordinacije. Ne treba ih identifikovati, jer se poruke ne usmeravaju na jedno određeno mesto nego samo trebaju biti prenete uz maksimalan napor od strane čvorova da se taj prenos odradi na predviđen način. Čvorovi mogu da napuste i ponovo se pridruže mreži po želji, prihvatajući lanac dokaza o radu kao dokaz onoga što se dogodilo dok ih nije bilo. Oni glasaju svojom procesorskom snagom, izražavajući svoje prihvatanje validnih blokova time što pokušavaju da ih nadgrade novim blokovima i odbacuju nevažeće blokove odbijanjem ih nadgrađuju. Sva potrebna pravila i podsticaji mogu se nametnuti ovim mehanizmom postizanja konsenzusa.

2025-05-22 12:25:49Since it's Bitcoin Pizza Day, I made a Bitcoin pizza!
To give it a Japanese twist, I made it a mentaiko pizza (※ mentaiko = spicy cod roe, a popular Japanese ingredient often used in pasta or rice dishes). For the Bitcoin logo, I used a salmon terrine.
Salmon Terrine
I cut out the "B" logo using hanpen (※ hanpen = a soft, white Japanese fish cake made from fish paste and yam). Tip: You can also cut a colored plastic folder into the "B" shape and place it on top as a stencil — makes it easier!
I blended salmon, hanpen, milk, egg, and a bit of salt in a food processor, poured it into a container, and baked it in a water bath.
Pizza Dough
I mixed bread flour, dry yeast, salt, olive oil, and water, then kneaded it with determination! Let it rise for about an hour until fluffy.
Mentaiko Mayo Topping
I mixed mentaiko, mayonnaise, and soy sauce.
I spread out the dough, added the mentaiko mayo, cheese, and corn, then baked it. Halfway through, I added thin slices of mochi (rice cake). After baking, I topped it with seaweed and the salmon terrine to finish!
Lots to reflect on
About the Terrine
In the video, you’ll see I divided the terrine into two portions. I was worried that the salmon and hanpen parts might end up looking too similar in color, making the “B” logo hard to see.
So for one half, I added ketchup, thinking: “Maybe this will make the red more vibrant?” But even with the ketchup, it didn’t change much.
The Mochi
I accidentally bought thinly sliced mochi, but I realized it might burn too easily as a pizza topping. Regular mochi with standard thickness is probably better.
I added the mochi halfway through baking, opening the oven once, but now I’m thinking that might have lowered the oven temp too much.
Lessons Learned
This was my first and only attempt—no test run beforehand— so I ended up with a long list of lessons learned. In the future, I should definitely do a trial version first… But you know… salmon and mentaiko are expensive! (excuses, excuses)
Cheese
I wanted to do that Instagram-worthy cheese pull moment, but nope. No stretch. None at all. I think that kind of thing needs a totally different kind of cheese or prep. Will have to experiment more.
Taste Test
Actually really good. I usually don’t eat mentaiko mayo myself, and I’m a Margherita pizza fan at heart. But this was surprisingly nice. A little rich in flavor—made me crave a bowl of rice. Next time, I might skip the soy sauce to tone it down a bit.

2025-05-21 00:24:36Yeah, I’m sure everything in the file is legit. 👍 Let’s review the guard witness testimony…Oh wait, they weren’t at their posts despite 24/7 survellience instructions after another Epstein “suicide” attempt two weeks earlier. Well, at least the video of the suicide is in the file? Oh wait, a techical glitch. Damn those coincidences!
At this point, the Trump administration has zero credibility with me on anything related to the Epstein case and his clients. I still suspect the administration is using the Epstein files as leverage to keep a lot of RINOs in line, whereas they’d be sabotaging his agenda at every turn otherwise. However, I just don’t believe in ends-justify-the-means thinking. It’s led almost all of DC to toss out every bit of the values they might once have had.

Autor: Vijay Boyapati / Prevod na hrvatski: Matija
Sa zadnjim cijenama koje je bitcoin dosegao 2017., optimističan scenarij za ulagače se možda čini toliko očitim da ga nije potrebno niti spominjati. Alternativno, možda se nekome čini glupo ulagati u digitalnu vrijednost koja ne počiva na nijednom fizičkom dobru ili vladi i čiji porast cijene su neki usporedili sa manijom tulipana ili dot-com balonom. Nijedno nije točno; optimističan scenarij za Bitcoin je uvjerljiv, ali ne i očit. Postoje značajni rizici kod ulaganja u Bitcoin, no, kao što planiram pokazati, postoji i ogromna prilika.
Geneza
Nikad u povijesti svijeta nije bilo moguće napraviti transfer vrijednosti među fizički udaljenim ljudima bez posrednika, poput banke ili vlade. 2008. godine, anonimni Satoshi Nakamoto je objavio 8 stranica rješenja na dugo nerješivi računalski problem poznat kao “Problem Bizantskog Generala.” Njegovo rješenje i sustav koji je izgradio - Bitcoin - dozvolio je, prvi put ikad, da se vrijednost prenosi brzo i daleko, bez ikakvih posrednika ili povjerenja. Implikacije kreacije Bitcoina su toliko duboke, ekonomski i računalski, da bi Nakamoto trebao biti prva osoba nominirana za Nobelovu nagradu za ekonomiju i Turingovu nagradu.
Za ulagače, važna činjenica izuma Bitcoina (mreže i protokola) je stvaranje novog oskudnog digitalnog dobra - bitcoina (monetarne jedinice). Bitcoini su prenosivi digitalni “novčići” (tokeni), proizvedeni na Bitcoin mreži kroz proces nazvan “rudarenje” (mining). Rudarenje Bitcoina je ugrubo usporedivo sa rudarenjem zlata, uz bitnu razliku da proizvodnja bitcoina prati unaprijed osmišljeni i predvidivi raspored. Samo 21 milijun bitcoina će ikad postojati, i većina (2017., kada je ovaj tekst napisan) su već izrudareni. Svake četiri godine, količina rudarenih bitcoina se prepolovi. Produkcija novih bitcoina će potpuno prestati 2140. godine.
Stopa inflacije —— Monetarna baza
Bitcoine ne podržava nikakva roba ili dobra, niti ih garantira ikakva vlada ili firma, što postavlja očito pitanje za svakog novog bitcoin ulagača: zašto imaju uopće ikakvu vrijednost? Za razliku od dionica, obveznica, nekretnina ili robe poput nafte i žita, bitcoine nije moguće vrednovati koristeći standardne ekonomske analize ili korisnost u proizvodnji drugih dobara. Bitcoini pripadaju sasvim drugoj kategoriji dobara - monetarnih dobara, čija se vrijednost definira kroz tzv. teoriju igara; svaki sudionik na tržištu vrednuje neko dobro, onoliko koliko procjenjuje da će ga drugi sudionici vrednovati. Kako bismo bolje razumjeli ovo svojstvo monetarnih dobara, trebamo istražiti podrijetlo novca.
Podrijetlo novca
U prvim ljudskim društvima, trgovina među grupama se vršila kroz robnu razmjenu. Velika neefikasnost prisutna u robnoj razmjeni je drastično ograničavala količinu i geografski prostor na kojem je bila moguća. Jedan od najvećih problema sa robnom razmjenom je problem dvostruke podudarnosti potražnje. Uzgajivač jabuka možda želi trgovati sa ribarom, ali ako ribar ne želi jabuke u istom trenutku, razmjena se neće dogoditi. Kroz vrijeme, ljudi su razvili želju za čuvanjem određenih predmeta zbog njihove rijetkosti i simbolične vrijednosti (npr. školjke, životinjski zube, kremen). Zaista, kako i Nick Szabo govori u svojem izvrsnom eseju o podrijetlu novca, ljudska želja za sakupljanjem predmeta pružila je izraženu evolucijsku prednost ranom čovjeku nad njegovim najbližim biološkim rivalom, neandertalcem - Homo neanderthalensis.
"Primarna i najbitnija evolucijska funkcija sakupljanja bila je osigurati medij za čuvanje i prenošenje vrijednosti".
Predmeti koje su ljudi sakupljali služili su kao svojevrsni “proto-novac,” tako što su omogućavale trgovinu među antagonističkim plemenima i dozvoljavale bogatsvu da se prenosi na sljedeću generaciju. Trgovina i transfer takvih predmeta bile su rijetke u paleolitskim društvima, te su oni služili više kao “spremište vrijednosti” (store of value) nego kao “medij razmjene” (medium of exchange), što je uloga koju danas igra moderni novac. Szabo objašnjava:
"U usporedbi sa modernim novcem, primitivan novac je imao jako malo “brzinu” - mogao je promijeniti ruke samo nekoliko puta u životu prosječnog čovjeka. Svejedno, trajni i čvrsti sakupljački predmet, što bismo danas nazvali “nasljeđe,” mogao je opstati mnogo generacija, dodajući znatnu vrijednost pri svakom transferu - i zapravo omogućiti transfer uopće".
Rani čovjek suočio se sa bitnom dilemom u teoriji igara, kada je odlučivao koje predmete sakupljati: koje od njih će drugi ljudi željeti? Onaj koji bi to točno predvidio imao bi ogromnu prednost u mogućnosti trgovine i akvizicije bogatsva. Neka američka indijanska plemena, npr. Naraganseti, specijalizirala su se u proizvodnji sakupljačkih dobara koja nisu imala drugu svrhu osim trgovine. Valja spomenuti da što je ranije predviđanje da će neko dobro imati takvu vrijednost, veća je prednost koju će imati onaj koji je posjeduje, zato što ju je moguće nabaviti jeftinije, prije nego postane vrlo tražena roba i njezona vrijednost naraste zajedno sa populacijom. Nadalje, nabava nekog dobra u nadi da će u budućnosti biti korišteno kao spremište vrijednosti, ubrzava upravo tu primjenu. Ova cirkularnost je zapravo povratna veza (feedback loop) koja potiče društva da se rapidno slože oko jednog spremišta vrijednosti. U terminima teorije igara, ovo je znano kao “Nashov ekvilibrij.” Postizanje Nashovog ekvilibrija za neko spremište vrijednosti je veliko postignuće za društvo, pošto ono znatno olakšava trgovinu i podjelu rada, i time omogućava napredak civilizacije.
Tisućljećima, kako su ljudska društva rasla i otvarala trgovinske puteve, različite aplikacije spremišta vrijednosti u individualnim društvima počele su se natjecati međusobno. Trgovci su imali izbor: čuvati svoju zaradu u spremištu vrijednosti vlastite kulture, ili one kulture sa kojom su trgovali, ili mješavini oboje. Benefit štednje u stranom spremištu vrijednosti bila je uvećana sposobnost trgovanja u povezanom stranom društvu. Trgovci koji su štedili u stranom spremištu vrijednosti su također imali dobrih razloga da potiču svoje društvo da ga prihvati, jer bi tako uvećali vrijednost vlastite ušteđevine. Prednosti “uvezene” tehnologije spremanja vrijednosti bile su prisutne ne samo za trgovce, nego i za sama društva. Kada bi se dvije grupe konvergirale u jedinstvenom spremištu vrijednosti, to bi značajno smanjilo cijenu troškova trgovine jednog s drugim, i samim time povećanje bogatstva kroz trgovinu. I zaista, 19. stoljeće bilo je prvi put da je najveći dio svijeta prihvatio jedinstveno spremište vrijednosti - zlato - i u tom periodu vidio najveću eksploziju trgovine u povijesti svijeta. O ovom mirnom periodu, pisao je John Maynard Keynes:
"Kakva nevjerojatna epizoda u ekonomskom napretku čovjeka… za svakog čovjeka iole iznadprosječnog, iz srednje ili više klase, život je nudio obilje, ugodu i mogućnosti, po niskoj cijeni i bez puno problema, više nego monarsima iz prethodnih perioda. Stanovnik Londona mogao je, ispijajući jutarnji čaj iz kreveta, telefonski naručiti razne proizvode iz cijele Zemlje, u količinama koje je želio, i sa dobrim razlogom očekivati njihovu dostavu na svoj kućni prag."
Svojstva dobrog spremišta vrijednosti
Kada se spremišta vrijednosti natječu jedno s drugim, specifična svojstva rade razliku koja daje jednom prednost nad drugim. Premda su mnoga dobra u prošlosti korištena kao spremišta vrijednosti ili kao “proto-novac,” određena svojstva su se pokazala kao posebno važna, i omogućila dobrima sa njima da pobijede. Idealno spremište vrijednosti biti će:
- Trajno: dobro ne smije biti kvarljivo ili lako uništeno. Tako naprimjer, žito nije idealno spremište vrijednosti.
- Prenosivo: dobro mora biti lako transportirati i čuvati, što omogućuje osiguranje protiv gubitka ili krađe i dopušta trgovinu na velike udaljenosti. Tako, krava je lošije spremište vrijednosti od zlatne narukvice.
- Zamjenjivo: jedna jedinica dobra treba biti zamjenjiva sa drugom. Bez zamjenjivosti, problem podudarnosti želja ostaje nerješiv. Time, zlato je bolje od dijamanata, jer su oni nepravilni u obliku i kvaliteti.
- Provjerljivo: dobro mora biti lako i brzo identificirano i testirano za autentičnost. Laka provjera povećava povjerenje u trgovini i vjerojatnost da će razmjena biti dovršena.
- Djeljivo: dobro mora biti lako djeljivo na manje dijelove. Premda je ovo svojstvo bilo manje važno u ranim društvima gdje je trgovina bila rijetka, postalo je važnije sa procvatom trgovine. Količine koje su se mijenjale postale su manje i preciznije.
- Oskudno: Monetarno dobro mora imati “cijenu nemoguću za lažirati,” kao što je rekao Nick Szabo. Drugim riječima, dobro ne smije biti obilno ili lako dostupno kroz proizvodnju. Oskudnost je možda i najvažnije svojstvo spremišta vrijednosti, pošto se izravno vezuje na ljudsku želju da sakupljamo ono što je rijetko. Ona je izvor vrijednosti u spremištu vrijednosti.
- Duge povijesti: što je dulje neko dobro vrijedno za društvo, veća je vjerojatnost da će biti prihvaćeno kao spremište vrijednosti. Dugo postojeće spremište vrijednosti biti će jako teško uklonjeno od strane došljaka, osim u slučaju sile (ratno osvajanje) ili ako je nova tehnologija znatno bolja u ostalim svojstvima.
- Otporno na cenzuru: novije svojstvo, sve više važno u modernom digitalnom svijetu sa sveprisutnim nadzorom, je otpornost na cenzuru. Drugim riječima, koliko je teško da vanjski agent, kao korporacija ili država, spriječi vlasnika dobra da ga čuva i koristi. Dobra koja su otporna na cenzuru su idealna za ljude koji žive u režimima koji prisilno nadziru kapital ili čine neke oblike mirne trgovine protuzakonitima.
Ova tablica ocjenjuje Bitcoin, zlato (gold) i fiat novac (kao što je euro ili dolar) po svojstvima izlistanim gore. Objašnjenje svake ocjene slijedi nakon tablice.
Trajnost:
Zlato je neosporeni kralj trajnosti. Velika većina zlata pronađenog kroz povijest, uključujući ono egipatskih faraona, opstaje i danas i vjerojatno će postojati i za tisuću godina. Zlatnici korišteni u antičko doba imaju značajnu vrijednost i danas. Fiat valute i bitcoini su digitalni zapisi koji ponekad imaju fizički oblik (npr. novčanice). Dakle, njihovu trajnost ne određuju njihova fizička svojstva (moguće je zamijeniti staru i oštećenu novčanicu za novu), nego institucije koje stoje iza njih. U slučaju fiat valuta, mnoge države su nastale i nestale kroz stoljeća, i valute su nestale s njima. Marke iz Weimarske republike danas nemaju vrijednost zato što institucija koja ih je izdavala više ne postoji. Ako je povijest ikakav pokazatelj, ne bi bilo mudro smatrati fiat valute trajnima dugoročno; američki dolar i britanska funta su relativne anomalije u ovom pogledu. Bitcoini, zato što nemaju instituciju koja ih održava, mogu se smatrati trajnima dok god mreža koja ih osigurava postoji. Obzirom da je Bitcoin još uvijek mlada valuta, prerano je za čvrste zaključke o njegovoj trajnosti. No, postoje ohrabrujući znakovi - prominente države su ga pokušavale regulirati, hakeri ga napadali - usprkos tome, mreža nastavlja funkcionirati, pokazujući visok stupanj antifragilnosti.
Prenosivost:
Bitcoini su najprenosivije spremište vrijednosti ikad. Privatni ključevi koji predstavljaju stotine milijuna dolara mogu se spremiti na USB drive i lako ponijeti bilo gdje. Nadalje, jednako velike sume mogu se poslati na drugi kraj svijeta skoro instantno. Fiat valute, zbog svojeg temeljno digitalnog oblika, su također lako prenosive. Ali, regulacije i kontrola kapitala od strane države mogu ugroziti velike prijenose vrijednosti, ili ih usporiti danima. Gotovina se može koristiti kako bi se izbjegle kontrole kapitala, ali onda rastu rizik čuvanja i cijena transporta. Zlato, zbog svojeg fizičkog oblika i velike gustoće, je najmanje prenosivo. Nije čudo da većina zlatnika i poluga nikad ne napuste sefove. Kada se radi prijenos zlata između prodavača i kupca, uglavnom se prenosi samo ugovor o vlasništvu, ne samo fizičko zlato. Prijenos fizičkog zlata na velike udaljenosti je skupo, riskantno i sporo.
Zamjenjivost:
Zlato nam daje standard za zamjenjivost. Kada je rastopljeno, gram zlata je praktički nemoguće razlikovati od bilo kojeg drugog grama, i zlato je oduvijek bilo takvo. S druge strane, fiat valute, su zamjenjive samo onoliko koliko njihova institucija želi da budu. Iako je uglavnom slučaj da je novčanica zamjenjiva za drugu istog iznosa, postoje situacije u kojima su velike novčanice tretirane drukčije od malih. Naprimjer, vlada Indije je, u pokušaju da uništi neoporezivo sivo tržište, potpuno oduzela vrijednost novčanicama od 500 i 1000 rupija. To je uzrokovalo da ljudi manje vrednuju te novčanice u trgovini, što je značilo da više nisu bile zaista zamjenjive za manje novčanice. Bitcoini su zamjenjivi na razini mreže; svaki bitcoin je pri prijenosu tretiran kao svaki drugi. No, zato što je moguće pratiti individualne bitcoine na blockchainu, određeni bitcoin može, u teoriji, postati “prljav” zbog korštenja u ilegalnoj trgovini, te ga trgovci ili mjenjačnice možda neće htjeti prihvatiti. Bez dodatnih poboljšanja oko privatnosti i anonimnosti na razini mrežnog protokola, bitcoine ne možemo smatrati jednako zamjenjivim kao zlato.
Mogućnost provjere:
Praktično gledajući, autentičnost fiat valuta i zlata je prilično lako provjeriti. Svejedno, i usprkos pokušajima da spriječe krivotvorenje novčanica, i dalje postoji potencijal prevare za vlade i njihove građane. Zlato također nije imuno na krivotvorenje. Sofisticirani kriminalci su koristili pozlaćeni tungsten kako bi prevarili kupce zlata. Bitcoine je moguće provjeriti sa matematičkom sigurnošću. Korištenjem kriptografskih potpisa, vlasnik bitcoina može javno demonstrirati da posjeduje bitcoine koje tvrdi da posjeduje.
Djeljivost:
Bitcoine je moguće podijeliti u stotinu milijuna manjih jedinica (zvanih satoshi), i prenositi takve (no, valja uzeti u obzir ekonomičnost prijenosa malih iznosa, zbog cijene osiguravanja mreže - “network fee”). Fiat valute su tipično dovoljno djeljive na jedinice sa vrlo niskom kupovnom moći. Zlato, iako fizički i teoretski djeljivo, postaje teško za korištenje kada se podijeli na dovoljno male količine da bi se moglo koristiti u svakodnevnoj trgovini.
Oskudnost:
Svojstvo koje najjasnije razlikuje Bitcoin od fiat valuta i zlata je njegova unaprijed definirana oskudnost. Od početka, konačna količina bitcoina nikad neće biti veća od 21 milijun. To daje vlasnicima bitcoina jasan i znan uvid u postotak ukupnog vlasništva. Naprimjer, vlasnik 10 bitcoina bi znao da najviše 2,1 milijuna ljudi (manje od 0.03% populacije) može ikad imati isto bitcoina kao i on. Premda je kroz povijest uvijek bilo oskudno, zlato nije imuno na povećanje ukupne količine. Ako se ikad izumi nova, ekonomičnija metoda rudarenja ili proizvodnje zlata, ukupna količina zlata bi se mogla dramatično povećati (npr. rudarenje morskog dna ili asteroida). Na kraju, fiat valute, relativno nov izum u povijesti, pokazale su se sklonima konstantnim povećanjima u količini. Države su pokazale stalnu sklonost inflaciji monetarne kvantitete kako bi rješavale kratkoročne političke probleme. Inflacijske tendencije vlada diljem svijeta čine fiat valute gotovo sigurnim da će gubiti vrijednost kroz vrijeme.
Etablirana povijest:
Nijedno monetarno dobro nema povijest kao zlato, koje je imalo vrijednost za cijelog trajanja ljudske civilizacije. Kovanice izrađene u antičko doba i danas imaju značajnu vrijednost. Ne može se isto reći za fiat valute, koje su same relativno nova povijesna anomalija. Od njihovog početka, fiat valute su imale gotovo univerzalni smjer prema bezvrijednosti. Korištenje inflacije kao podmuklog načina za nevidljivo oporezivanje građana je vječita kušnja kojoj se skoro nijedna država u povijesti nije mogla oduprijeti. Ako je 20. stoljeće, u kojem je fiat novac dominirao globalni monetarni poredak, demonstriralo neku ekonomsku istinu, to je onda bila ta da ne možemo računati na fiat novac da održi vrijednost u dužem ili srednjem vremenskom periodu. Bitcoin, usprkos svojoj novosti, je preživio dovoljno testova tržišta da postoji velika vjerojatnost da neće nestati kao vrijedno dobro. Nadalje, Lindy efekt govori da što duže Bitcoin bude korišten, to će veća biti vjera u njega i njegovu sposobnost da nastavi postojati dugo u budućnost. Drugim riječima, društvena vjera u monetarno dobro je asimptotička, kao u grafu ispod:
Ako Bitcoin preživi prvih 20 godina, imat će gotovo sveopće povjerenje da će trajati zauvijek, kao što ljudi vjeruju da je internet trajna stvar u modernom svijetu.
Otpor na cenzuru
Jedan od najbitnijih izvora za ranu potražnju bitcoina bila je njegova upotreba u ilegalnoj kupovini i prodaji droge. Mnogi su zato pogrešno zaključili da je primarna potražnja za bitcoinima utemeljena u njihovoj prividnoj anonimnosti. Međutim, Bitcoin nije anonimna valuta; svaka transakcija na mreži je zauvijek zapisana na javnom blockchainu. Povijesni zapis transakcija dozvoljava forenzičkoj analizi da identificira izvore i tijek sredstava. Takva analiza dovela je do uhićenja počinitelja zloglasne MtGox pljačke. Premda je istina da dovoljno oprezna i pedantna osoba može sakriti svoj identitet koristeći Bitcoin, to nije razlog zašto je Bitcoin bio toliko popularan u trgovini drogom.
Ključno svojstvo koje čini Bitcoin najboljim za takve aktivnosti je njegova agnostičnost i nepotrebnost za dozvolom (“premissionlessness”) na mrežnoj razini. Kada se bitcoini prenose na Bitcoin mreži, ne postoji nitko tko dopušta transakcije. Bitcoin je distribuirana peer-to-peer (korisnik-korisniku) mreža, i samim time dizajnirana da bude otporna na cenzuru. Ovo je u velikom kontrastu sa fiat bankarskim sustavom, u kojem države reguliraju banke i ostale institucije prijenosa novca, kako bi one prijavljivale i sprječavale protuzakonito korištenje monetarnih dobara. Klasičan primjer regulacije novca su kontrole kapitala. Npr., bogati milijunaš će vrlo teško prenijeti svoje bogatstvo u novu zemlju, kada bježi iz opresivnog režima. Premda zlato nije izdano i proizvedeno od države, njegova fizička priroda ga čini teško prenosivim kroz prostor, i samim time ga je daleko lakše regulirati nego Bitcoin. Indijski Akt kontrole zlata je primjer takve regulacije.
Bitcoin je odličan u većini gore navedenih svojstava, što mu omogućava da bude marginalno bolji od modernih i drevnih monetarnih dobara, te da pruži poticaje za svoje rastuće društveno usvajanje. Specifično, moćna kombinacija otpornosti na cenzuru i apsolutne oskudnosti bila je velika motivacija za bogate ulagače koji su uložili dio svojeg bogatstva u Bitcoin.
Evolucija novca
U modernoj monetarnoj ekonomiji postoji opsesija sa ulogom novca kao medija razmjene. U 20. stoljeću, države su monopolizirale izdavanje i kontrolu novca i kontinuirano potkopavale njegovo svojstvo spremišta vrijednosti, stvarajući lažno uvjerenje da je primarna svrha novca biti medij razmjene. Mnogi su kritizirali Bitcoin, govoreći da je neprikladan da bude novac zato što mu je cijena bila previše volatilna za medij razmjene. No, novac je uvijek evoluirao kroz etape; uloga spremišta vrijednosti je dolazila prije medija razmjene. Jedan od očeva marginalističke ekonomije, William Stanley Jevons, objašnjava:
"Povijesno govoreći… čini se da je zlato prvo služilo kao luksuzni metal za ukras; drugo, kao sačuvana vrijednost; treće, kao medij razmjene; i konačno, kao mjerilo vrijednosti."
U modernoj terminologiji, novac uvijek evoluira kroz četiri stadija:
- Kolekcionarstvo: U prvoj fazi svoje evolucije, novac je tražen samo zbog svojih posebnih svojstava, uglavnom zbog želja onog koji ga posjeduje. Školjke, perlice i zlato su bili sakupljani prije nego su poprimili poznatije uloge novca.
- Spremište vrijednosti: Jednom kada je novac tražen od dovoljnog broja ljudi, biti će prepoznat kao način za čuvanje i spremanje vrijednosti kroz vrijeme. Kada neko dobro postane široko korišteno kao spremište vrijednosti, njegova kupovna moć raste sa povećanom potražnjom za tu svrhu. Kupovna moć spremišta vrijednosti će u jednom trenutku doći do vrhunca, kada je dovolno rašireno i broj novih ljudi koji ga potražuju splasne.
- Sredstvo razmjene: Kada je novac potpuno etabliran kao spremište vrijednosti, njegova kupovna moć se stabilizira. Nakon toga, postane prikladno sredstvo razmjene zbog stabilnosti svoje cijene. U najranijim danima Bitcoina, mnogi ljudi nisu shvaćali koju buduću cijenu plaćaju koristeći bitcoine kao sredstvo razmjene, umjesto kao novonastalo spremište vrijednosti. Poznata priča o čovjeku koji je za 10,000 bitcoina (vrijednih oko 94 milijuna dolara kada je ovaj članak napisan) za dvije pizze ilustrira ovaj problem.
- Jedinica računanja vrijednosti: Jednom kada je novac široko korišten kao sredstvo razmjene, dobra će biti vrednovana u njemu, tj. većina cijena će biti izražena u njemu. Uobičajena zabluda je da je većinu dobara moguće zamijeniti za bitcoine danas. Npr., premda je možda moguće kupiti šalicu kave za bitcoine, izlistana cijena nije prava bitcoin cijena; zapravo se radi o cijeni u državnoj valuti koju želi trgovac, preračunatu u bitcoin po trenutnoj tržišnoj cijeni. Kad bi cijena bitcoina pala u odnosu na valutu, vrijednost šalice izražena u bitcoinima bi se povećala. Od trenutka kada trgovci budu voljni prihvaćani bitcoine kao platežno sredstvo, bez obraćanja pažnje na vrijednost bitcoina u državnoj fiat valuti, moći ćemo reći da je Bitcoin zaista postao jedinica računanja vrijednosti.
Monetarna dobra koja još nisu jedinice računanja vrijednosti možemo smatrati “djelomično monetiziranima.” Danas zlato ima takvu ulogu, jer je spremište vrijednosti, ali su mu uloge sredstva razmjene i računanja vrijednosti oduzete intervencijama država. Moguće je također da se jedno dobro koristi kao sredstvo razmjene, dok druga ispunjavaju ostale uloge. To je tipično u zemljama gdje je država disfunkcionalna, npr. Argentina ili Zimbabwe. U svojoj knjizi, Digitalno zlato, Nathaniel Popper piše:
"U Americi, dolar služi trima funkcijama novca: nudi sredstvo razmjene, jedinicu za mjerenje vrijednosti dobara, i mjesto gdje se može čuvati vrijednosti. S druge strane, argentinski peso je korišten kao sredstvo razmjene (za svakodnevne potrebe), ali ga nitko nije koristio kao spremište vrijednosti. Štednja u pesosima bila je ekvivalent bacanja novca. Zato su ljudi svu svoju štednju imali u dolarima, jer je dolar bolje čuvao vrijednost. Zbog volatilnosti pesosa, ljudi su računali cijene u dolarima, što im je pružalo pouzdaniju jedinicu mjerenja kroz vrijeme."
Bitcoin je trenutno u fazi tranzicije iz prvog stadija monetizacije u drugi. Vjerojatno će proći nekoliko godina prije nego Bitcoin pređe iz začetaka spremišta vrijednosti u istinski medij razmjene, i put do tog trenutka je još uvijek pun rizika i nesigurnosti. Važno je napomenuti da je ista tranzicija trajala mnogo stoljeća za zlato. Nitko danas živ nije doživio monetizaciju dobra u realnom vremenu (kroz koju Bitcoin prolazi), tako da nemamo puno iskustva govoriti o putu i načinu na koji će se monetizacija dogoditi.
Put monetizacije
Kroz proces monetizacije, monetarno dobro će naglo porasti u kupovnoj moći. Mnogi su tako komentirali da je uvećanje kupovne moći Bitcoina izgledalo kao “balon” (bubble). Premda je ovaj termin često korišten kako bi ukazao na pretjeranu vrijednosti Bitcoina, sasvim slučajno je prikladan. Svojstvo koje je uobičajeno za sva monetarna dobra jest da je njihova kupovna moć viša nego što se može opravdati samo kroz njihovu uporabnu vrijednost. Zaista, mnogi povijesni novci nisu imali uporabnu vrijednost. Razliku između kupovne moći i vrijednosti razmjene koju bi novac mogao imati za svoju inherentnu korisnost, možemo razmatrati kao “monetarnu premiju.” Kako monetarno dobro prolazi kroz stadije monetizacije (navedene gore), monetarna premija raste. No, ta premija ne raste u ravnoj i predvidivoj liniji. Dobro X, koje je bilo u procesu monetizacije, može izgubiti u usporedbi sa dobrom Y koje ima više svojstava novca, te monetarna premija dobra X drastično padne ili potpuno nestane. Monetarna premija srebra je skoro potpuno nestala u kasnom 19. stoljeću, kada su ga vlade diljem svijeta zamijenile zlatom kao novcem.
Čak i u odsustvu vanjskih faktora, kao što su intervencije vlade ili druga monetarna dobra, monetarna premija novog novca neće ići predvidivim putem. Ekonomist Larry White primijetio je:
"problem sa pričom “balona,” naravno, je da je ona konzistentna sa svakim putem cijene, i time ne daje ikakvo objašnjenje za specifičan put cijene"
Proces monetizacije opisuje teorija igara; svaki akter na tržištu pokušava predvidjeti agregiranu potražnju ostalih aktera, i time buduću monetarnu premiju. Zato što je monetarna premija nevezana za inherentnu korisnost, tržišni akteri se uglavnom vode za prošlim cijenama da bi odredili je li neko dobro jeftino ili skupo, i žele li ga kupiti ili prodati. Veza trenutne potražnje sa prošlim cijenama naziva se “ovisnost o putu” (path dependence); ona je možda najveći izvor konfuzije u shvaćanju kretanja cijena monetarnih dobara.
Kada kupovna moć monetarnog dobra naraste zbog većeg i šireg korištenja, očekivanja tržišta o definicijama “jeftinog” i “skupog” se mijenjaju u skladu s time. Slično tome, kada cijena monetarnog dobra padne, očekivanja tržišta mogu se promijeniti u opće vjerovanje da su prethodne cijene bile “iracionalne” ili prenapuhane. Ovisnost o putu novca ilustrirana je riječima poznatog upravitelja fondova s Wall Streeta, Josha Browna:
"Kupio sam bitcoine kada su koštali 2300 USD, i to mi se udvostručilo gotovo odmah. Onda sam počeo govoriti kako “ne mogu kupiti još” dok im je cijena rasla, premda sam znao da je to razmišljanje bazirano samo na cijenu po kojoj sam ih kupio. Kasnije, kada je cijena pala zbog kineske regulacije mjenjačnica, počeo sam si govoriti, “Odlično, nadam se da će još pasti da mogu kupiti još.”"
Istina leži u tome da su ideje “jeftinog” i “skupog” zapravo besmislene kada govorimo o monetarnim dobrima. Cijena monetarnog dobra ne reflektira njegovu stopu rasprostanjenosti ili korisnosti, nego mjeru koliko je ono široko prihvaćeno da ispuni razne uloge novca.
Dodatna komplikacija u ovom aspektu novca je činjenica da tržišni akteri ne djeluju samo kao nepristrani promatrači koji pokušavaju kupiti i prodati u iščekivanju budućih kretanja monetarne premije, nego i kao aktivni proponenti. Pošto ne postoji objektivno “točna” monetarna premija, širiti dobar glas o superiornijim svojstvima nekog monetarnog dobra je efektivnije nego za obična dobra, čija vrijednost je u konačnici vezana na njegovu osnovnu korisnost. Religiozni zanos sudionika na Bitcoin tržištu vidljiv je na raznim internetskim forumima, gdje Bitcoineri aktivno promoviraju benefine Bitcoina i bogatstvo koje je moguće ostvariti investiranjem u njega. Promatrajući Bitcoin tržište, Leigh Drogen komentira:
"To je prepoznatljivo svima kao religija - priča koju si pričamo i oko koje se slažemo. Religija je krivulja na grafu prihvaćanja o kojoj trebamo razmišljati. Sustav je gotovo savršen - onog trenutka kada netko pristupi krugu Bitcoinera, to će reći svima i nastaviti širiti riječ. Onda njihovi prijatelji pristupe i nastave širiti riječ."
Premda usporedba sa religijom može staviti Bitcoin u iracionalno svjetlo, potpuno je racionalno za individualnog vlasnika da širi dobru vijest o superiornom monetarnom dobru, i za šire društvo da se standardizira oko njega. Novac djeluje kao temelj za svu trgovinu i štednju; tako da prihvaćanje superiornog oblika novca ima ogromne multiplicirajuće benefite za stvaranje bogatstva za sve članove društva.
Oblik monetizacije
U članku o Spekulativnom prihvaćanju Bitcoina / teorije cijene, Michael Casey postulira da rastući Gartner hype ciklusi predstavljaju faze standardne S-krivulje prihvaćanja novih tehnologija, koje su bile prisutne kod mnogih transformacijskih tehnologija dok su postajale uobičajene u društvu.
Svaki Gartner hype ciklus počinje sa eksplozijom entuzijazma za novom tehnologijom, a cijenu podižu oni sudionici na tržištvu koji su “dostupni” u toj fazi. Najraniji kupci u Gartner hype ciklusu obično imaju jaku vjeru o transformacijskoj prirodi tehnologije u koju ulažu. S vremenom, tržište dosegne vrhunac entuzijazma kako se količina novih kupaca iscrpljuje, te kupovinom počnu dominirati spekulatori koji su više zainteresirani u brze profite nego u samu tehnologiju.
Nakon vrha hype ciklusa, cijene rapidno padaju dok spekulativno ludilo ustupa mjesto očajavanju, javnoj poruzi i osjećaju da tehnologija nije uopće bila transformacijska. S vremenom, cijena dosegne dno i formira plato na kojem se originalnim ulagačima, koji su imali snažno uvjerenje, pridružuju nove grupe ljudi koji su izdržali bol kraha cijena i koji cijene važnost same tehnologije.
Plato traje neko vrijeme i formira, kako Casey kaže, “stabilnu, dosadnu dolinu.” Za ovo vrijeme, javni interes za tehnologiju opada, no nastaviti će se razvijati i snažna zajednica uvjerenja će polako rasti. Tada, postavlja se nova baza za sljedeću iteraciju hype ciklusa, dok vanjski promatrači prepoznaju da tehnologija i dalje postoji i da ulaganje u nju možda nije onoliko rizično kao što se činilo za vrijeme pada cijene. Sljedeća iteracija hype ciklusa donosi mnogo veći broj novih ljudi, pa je i ciklus daleko veći u svojoj magnitudi.
Jako mali broj ljudi koji sudjeluju u Gartner hype ciklusu će točno predvidjeti koliko će visoko cijena porasti za vrijeme ciklusa. Cijene često dosegnu razine koje bi se činile apsurdnima većini ulagača u raniji stadijima ciklusa. Kada ciklus završi, mediji tipično atribuiraju pad cijene nekoj od aktualnih drušvenih tema. Premda takva tema može biti okidač pada, ona nikad nije temeljni razlog zašto ciklus završava. Gartner hype ciklusi završavaju kada je količina dostupnih novih sudionika na tržištu iscrpljena.
Zanimljivo je da je i zlato nacrtalo klasičan graf Gartner hype ciklusa od kasnih 1970-ih do ranih 2000-ih. Moguće je spekulirati da je hype ciklus osnovna socijalna dinamika oko procesa monetizacije.
Gartner kohorte
Od početka trgovanja Bitcoina na mjenjačnicama 2010. godine, Bitcoin tržište je svjedočilo četirima velikim Gartner hype ciklusima. U retrospektivi, možemo vrlo precizno identificirati grupe cijena prethodnih hype ciklusa Bitcoin tržišta. Također, možemo kvalitativno odrediti kohorte ulagača koje su povezane sa svakom iteracijom prethodnih ciklusa.
0 USD –1 USD (2009. – 3. mjesec 2011.): Prvi hype ciklus u Bitcoin tržištu dominirali su kriptografi, računalni znanstvenici i cypherpunkovi koji su od početka bili spremni razumijeti važnost nevjerojatnog izuma Satoshija Nakamotoa, i koji su bili pioniri u potvrđivanju da Bitcoin protokol nema tehničkih mana.
1 USD - 30 USD (3. mjesec 2011. – 7. mjesec. 2011.): Drugi ciklus privukao je rane entuzijaste oko novih tehnologija kao i stabilan pritok ideološki motiviranih ulagača koji su bili oduševljeni idejom novca odvojenog od države. Libertarijanci poput Rogera Vera došli su u Bitcoin zbog aktivnog anti-institucionalnog stava, i mogućnosti koju je nova tehnologija obećavala. Wences Casares, briljantni i dobro povezani serijski poduzetnik, bio je također dio drugog Bitcoin hype ciklusa te je širio riječ o Bitcoinu među najprominentnijim tehnolozima i ulagačima u Silicijskoj Dolini.
250 USD – 1100 USD (4. mjesec 2013. – 12. mjesec 2013.): Treći hype ciklus doživio je ulazak ranih generalnih i institucionalnih ulagača koji su bili voljni uložiti trud i riskirati kroz užasno komplicirane kanale likvidnosti kako bi kupili bitcoine. Primaran izvor likvidnosti na tržištu za vrijeme ovog perioda bio je MtGox, mjenjačnica bazirana u Japanu, koju je vodio notorno nesposobni i beskrupulozni Mark Karpeles, koji je kasnije završio i u zatvoru zbog svoje uloge u kolapsu MtGoxa.
Valja primijetiti da je rast Bitcoinove cijene za vrijeme spomenuti hype ciklusa većinom povezano sa povećanjem likvidnosti i lakoćom sa kojom su ulagači mogli kupiti bitcoine. Za vrijeme prvog hype ciklusa, nisu postojale mjenjačnice; akvizicija bitcoina se odvijala primarno kroz rudarenje (mining) ili kroz izravnu razmjenu sa onima koju su već izrudarili bitcoine. Za vrijeme drugog hype ciklusa, pojavile su se rudimentarne mjenjačnice, no nabavljanje i osiguravanje bitcoina na ovim mjenjačnicama bilo je previše kompleksno za sve osim tehnološki najsposobnijih ulagača. Čak i za vrijeme trećeg hype ciklusa, ulagači koju su slali novac na MtGox kako bi kupili bitcoine su morali raditi kroz značajne prepreke. Banke nisu bile voljne imati posla sa mjenjačnicom, a oni posrednici koji su nudili usluge transfera bili su često nesposobni, kriminalni, ili oboje. Nadalje, mnogi koji su uspjeli poslati novac MtGoxu, u konačnici su morali prihvatiti gubitak svojih sredstava kada je mjenjačnica hakirana i kasnije zatvorena.
Tek nakon kolapsa MtGox mjenjačnice i dvogodišnje pauze u tržišnoj cijeni Bitcoina, razvili su se zreli i duboki izvori likvidnosti; primjeri poput reguliranih mjenjačnica kao što su GDAX i OTC brokeri kao Cumberland mining. Dok je četvrti hype ciklus započeo 2016. godine, bilo je relativno lako običnim ulagačima kupiti i osigurati bitcoine.
1100 USD – 19600 USD? (2014. –?):
U trenutku pisanja ovog teksta, tržište Bitcoina je prolazilo svoj četvrti veliki hype ciklus. Sudjelovanje u ovom hype ciklusu dominirala je ona skupina koju je Michael Casey opisao kao “rana većina” običnih i institucionalnih ulagača.
Kako su se izvori likvidnosti produbljivali i sazrijevali, veliki institucionalni ulagači sada imaju priliku sudjelovati kroz regulirana “futures” tržišta. Dostupnosti takvih tržišta stvara put ka kreaciji Bitcoin ETF-a (exchange traded fund) (fond na slobodnom tržištu), koji će onda pokrenuti “kasnu većinu” i “najsporije” u sljedećim hype ciklusima.
Premda je nemoguće predvidjeti točan efekt budućih hype ciklusa, razumno je očekivati da će najviša točka biti između 20.000 USD i 50.000 USD (2021. zenit je bio preko 69.000 USD). Znatno više od ovog raspona, i Bitcoin bi imao znatan postotak ukupne vijednosti zlata (zlato i Bitcoin bi imali jednaku tržišnu kapitalizaciju kada bi bitcoini vrijedili oko 380.000 USD u trenutku pisanja ovog teksta). Značajan postotak vrijednosti zlata dolazi od potražnje centralnih banaka, te je malo vjerojatno da će centralne banke ili suverene države sudjelovati u trenutnom hype ciklusu.
Ulazak suverenih država u Bitcoin
Bitcoinov zadnji Gartner hype ciklus će započeti kada ga suverene države počnu akumulirati kao dio svojih rezervi stranih valuta. Tržišna kapitalizacija Bitcoina je trenutno premala da bismo ga smatrali značajnim dodatkom rezervama većini zemalja. No, kako se interes u privatnom sektoru povećava i kapitalizacija Bitcoina se približi trilijunu dolara, postat će dovoljno likvidan za većinu država. Prva država koja službeno doda bitcoine u svoje rezerve će vjerojatno potaknuti stampedo ostalih da učine isto. Države koje su među prvima u usvajanju Bitcoina imat će najviše benefita u svojim knjigama ako Bitcoin u konačnici postane globalna valuta (global reserve currency). Nažalost, vjerojatno će države sa najjačom izvršnom vlasti - diktature poput Sjeverne Koreje - biti najbrže u akumulaciji bitcoina. Neodobravanje prema takvim državama i slaba izvršna tijela zapadnjačkih demokracija uzrokovat će sporost i kašnjenje u akumulaciji bitcoina za njihove vlastite rezerve.
Velika je ironija u tome što je SAD trenutno jedna od regulatorno najotvorenijih nacija prema Bitcoinu, dok su Kina i Rusija najzatvorenije. SAD riskira najviše, geopolitički, ako bi Bitcoin zamijenio dolar kao svjetska rezervna valuta. U 1960-ima, Charles de Gaulle je kritizirao “pretjeranu privilegiju” (“exorbitant privilege”) koju su SAD imale u međunarodnom monetarnom poretku, postavljenom kroz Bretton Woods dogovor 1944. godine. Ruska i kineska vlada još ne shvaćaju geo-strateške benefite Bitcoina kao rezervne valute, te se trenutno brinu o efektima koje bi mogao imati na njihova unutarnja tržišta. Kao de Gaulle u 1960-ima, koji je prijetio SAD-u povratkom na klasični standard zlata, Kinezi i Rusi će s vremenom uvidjeti korist u velikoj poziciji u Bitcoinu - spremištu vrijednosti bez pokrića ijedne vlade. Sa najvećom koncentracijom rudara Bitcoina u Kini (2017.), kineska vlada već ima znatnu potencijalnu prednost u stavljanju bitcoina u svoje rezerve.
SAD se ponosi svojim statusom nacije inovatora, sa Silicijskom dolinom kao krunom svoje ekonomije. Dosad, Silicijska dolina je dominirala konverzacijom usmjerenom prema regulaciji, i poziciji koju bi ona treba zauzeti prema Bitcoinu. No, bankovna industrija i federalna rezerva SAD-a (US Federal Reserve, Fed) napokon počinju uviđati egzistencijalnu prijetnju koju Bitcoin predstavlja za američku monetarnu politiku, postankom globalne rezervne valute. Wall Street Journal, jedan od medijskih glasova federalne reserve, izdao je komentar o Bitcoinu kao prijetnji monetarnoj politici SAD-a:
"Postoji još jedna opasnost, možda i ozbiljnija iz perspektive centralnih banaka i regulatora: bitcoin možda ne propadne. Ako je spekulativni žar u kriptovalutu samo prvi pokazatelj njezinog šireg korištenja kao alternative dolaru, Bitcoin će svakako ugroziti monopol centralnih banaka nad novcem."
U narednim godinama, možemo očekivati veliku borbu između poduzetnika i inovatora u Silicijskoj dolini, koji će pokušavati čuvati Bitcoin od državne kontrole s jedne strane, i bankovne industrije i centralnih banaka koje će učiniti sve što mogu da bi regulirale Bitcoin kako bi spriječile znatne promjene u svojoj industriji i moći izdavanja novca, s druge.
Prijelaz na medij razmjene
Monetarno dobro ne može postati opće prihvaćen medij razmjene (standardna ekonomska definicija za “novac”) prije nego je vrednovano od širokog spektra ljudi; jednostavno, dobro koje nije vrednovano neće biti prihvaćeno u razmjeni. Kroz proces generalnog rasta vrijednosti, i time postanka spremišta vrijednosti, monetarno dobro će brzo narasti u kupovnoj moći, i time stvoriti cijenu za korištenje u razmjeni. Samo kada ta cijena rizika mijenjanja spremišta vrijednosti padne dovoljno nisko, može dobro postati opće prihvaćen medij razmjene.
Preciznije, monetarno dobro će biti prikladno kao medij razmjene samo kada je suma cijene rizika i transakcijske cijene u razmjeni manja nego u trgovini bez tog dobra.
U društvu koje vrši robnu razmjenu, prijelaz spremišta vrijednosti u medij razmjene može se dogoditi čak i onda kada monetarno dobro raste u kupovnoj moći, zato što su transakcijski troškovi robne razmjene iznimno visoki. U razvijenoj ekonomiji, u kojoj su troškovi razmjene niski, moguće je za mladu i rapidno rastućnu tehnologiju spremišta vrijednosti, poput Bitcoina, da se koristi kao medij razmjene, doduše na ograničen način. Jedan primjer je ilegalno tržište droge, gdje su kupci voljni žrtvovati oportunu cijenu čuvanja bitcoina kako bi umanjili znatan rizik kupovine droge koristeći fiat novac.
Postoje međutim velike institucionalne barijere da novonastalo spremište vrijednosti postane sveopće prihvaćen medij razmjene u razvijenom društvu. Države koriste oporezivanje kao moćnu metodu zaštite svojeg suverenog novca protiv rivalskih monetarnih dobara. Ne samo da suvereni novac ima prednost konstantnog izvora potražnje, zato što je porez moguće platiti jedino u njemu, nego su i rivalska monetarna dobra oporezana pri svakoj razmjeni za vrijeme rastuće cijene. Ova metoda oporezivanja stvara znatan otpor korištenju spremišta vrijednosti kao medija razmjene.
Ovakvo sabotiranje tržišnih monetarnih dobara nije nepremostiva barijera za njihovo prihvaćanje kao općeg medija razmjene. Ako ljudi izgube vjeru u suvereni novac, njegova vrijednost može rapidno propasti kroz proces zvan hiperinflacija. Kada suvereni novac prolazi kroz hiperinflaciju, njegova vrijednost propadne prvo u usporedbi sa najlikvidnijim dobrima u društvu, kao što je zlato ili stabilna strana valuta (američki dolar npr.), ako su ona dostupna. Kada nema likvidnih dobara ili ih ima premalo, novac u hiperinflaciji kolabira u usporedbi sa stvarnim dobrima, kao što su nekretnine ili upotrebljiva roba. Arhetipska slika hiperinflacije je trgovina sa praznim policama - potrošači brzo bježe iz propadajuće vrijednosti novca svoje nacije.
Nakon dovoljno vremena, kada je vjera potpuno uništena za vrijeme hiperinflacije, suvereni novac više nitko ne prihvaća, te se društvo može vratiti na robnu razmjenu, ili će doživjeti potpunu zamjenu monetarne jedinice za sredstvo razmjene. Primjer ovog procesa bila je zamjena zimbabveanskog dolara za američki dolar. Takva promjena suverenog novca za stranu valutu je dodatno otežana relativnom oskudnošću strane valute i odsustvom stranih bankarskih institucija koje pružaju likvidnost tržištu.
Sposobnost lakog prenošenja bitcoina preko granica i odsustvo potrebe za bankarskim sustavom čine Bitcoin idealnim monetarnim dobrom za one ljude koji pate pod hiperinflacijom. U nadolazećim godinama, kako fiat valute nastave svoj povijesni trend ka bezvrijednosti, Bitcoin će postati sve popularniji izbor za ušteđevine ljudi diljem svijeta. Kada je novac nacije napušten i zamijenjen Bitcoinom, Bitcoin će napraviti tranziciju iz spremišta vrijednosti u tom društvu u opće prihvaćeno sredstvo razmjene. Daniel Krawicz stvorio je termin “hiperbitcoinizacija” da bi opisao ovaj proces.
Učestala pogrešna shvaćanja
Većina ovog članka usredotočila se na monetarnu prirodu Bitcoina. Sa tim temeljima možemo adresirati neke od najčešćih nerazumijevanja u Bitcoinu.
Bitcoin je balon (bubble)
Bitcoin, kao sva tržišna monetarna dobra, posjeduje monetarnu premiju. Ona često rezultira uobičajenom kritikom da je Bitcoin samo “balon.” No, sva monetarna dobra imaju monetarnu premiju. Naprotiv, ta monetarna premija (cijena viša od one koju diktira potražnja za dobrom kao korisnim) je upravo karakteristična za sve oblike novca. Drugim riječima, novac je uvijek i svuda balon. Paradoksalno, monetarno dobro je istovremeno balon i ispod vrijednosti ukoliko je u ranijim stadijima općeg prihvaćanja kao novac.
Bitcoin je previše volatilan
Volatilnost cijene Bitcoina je funkcija njegovog nedavnog nastanka. U prvih nekoliko godina svojeg postojanja, Bitcoin se ponašao kao mala dionica, i svaki veliki kupac - kao npr. braća Winklevoss - mogao je uzrokovati veliki skok u njegovoj cijeni. No, kako su se prihvaćenost i likvidnost povećavali kroz godine, volatilnost Bitcoina je srazmjerno smanjila. Kada Bitcoin postigne tržišnu kapitalizaciju (vrijednost) zlata, imat će sličnu volatilnost kao i zlato. Kako Bitcoin nastavi rasti, njegova volatilnost će se smanjiti do razine koja ga čini prikladnim za široko korištenje kao medij razmjene. Kao što je prethodno rečeno, monetizacija Bitcoina se odvija u seriji Gartner hype ciklusa. Volatilnost je najniža za vrijeme vrhunaca i dolina unutar ciklusa. Svaki hype ciklus ima nižu volatilnost od prethodnih, zato što je likvidnost tržišta veća.
Cijene transakcija su previsoke
Novija kritika Bitcoin mreže je ta da ju je povećanje cijena prijenosa bitcoina učinilo neprikladnom za sustav plaćanja. No, rast u cijenama transakcija je zdrav i očekivan. One su nužne za plaćanje bitcoin minera (rudara), koji osiguravaju mrežu validacijom transakcija. Rudare se plaća kroz cijene transakcija ili kroz blok-nagrade, koje su inflacijska subvencija od trane trenutnih vlasnika bitcoina.
S obzirom na Bitcoinovu fiksnu proizvodnju (monetarna politika koja ga čini idealnim za spremanje vrijednosti), blok-nagrade će s vremenom nestati i mrežu će se u konačnici morati osiguravati kroz cijene transakcija. Mreža sa “niskim” cijenama transakcija je mreža sa slabom sigurnosti i osjetljiva na vanjsku intervenciju i cenzuru. Oni koji hvale niske cijene Bitcoinovih alternative zapravo niti ne znajući opisuju slabosti tih takozvanih “alt-coina.”
Površan temelj kritika Bitcoinovih “visokih” cijena transakcija je uvjerenje da bi Bitcoin trebao biti prvo sustav plaćanja, i drugo spremište vrijednosti. Kao što smo vidjeli kroz povijest novca, ovo uvjerenje je naopako. Samo onda kada Bitcoin postane duboko ukorijenjeno spremište novca može biti prikladan kao sredstvo razmjene. Nadalje, kada oportunitetni trošak razmjene bitcoina dođe na razinu koja ga čini prikladnim sredstvom razmjene, većina trgovine neće se odvijati na samoj Bitcoin mreži, nego na mrežama “drugog sloja” (second layer) koje će imati niže cijene transakcija. Takve mreže, poput Lightning mreže, služe kao moderna verzija zadužnica koje su korištene za prijenos vlasničkih papira zlata u 19. stoljeću. Banke su koristile zadužnice zato što je prijenos samog metala bio daleko skuplji. Za razliku od takvih zadužnica, Lightning mreža će omogućavati nisku cijenu prijenosa bitcoina bez potrebe za povjerenjem prema trećoj strani, poput banaka. Razvoj Lightning mreže je tehnološka inovacija od izuzetne važnosti u povijesti Bitcoina, i njezina vrijednost će postati očita u narednim godinama, kako je sve više ljudi bude razvijalo i koristilo.
Konkurencija
Pošto je Bitcoin softverski protokol otvorenog tipa (open-source), oduvijek je bilo moguće kopirati softver i imitirati mrežu. Kroz godine nastajali su mnogi imitatori, od identičnih kopija, kao Litecoin, do kompleksnijih varijanti kao što je Ethereum, koje obećavaju arbitrarno kompleksne ugovorne mehanizme koristeći decentralizirani računalni sustav. Česta kritika Bitcoinu od strane ulagača je ta da on ne može zadržati svoju vrijednost kada je vrlo lako stvoriti konkurente koji mogu lako i brzo u sebi imati najnovije inovacije i softverske funkcionalnosti.
Greška u ovom argumentu leži u manju takozvanog “mrežnog efekta” (network effect), koji postoji u prvoj i dominantnoj tehnologiji u nekom području. Mrežni efekt - velika vrijednost korištenja Bitcoina samo zato što je već dominantan - je važno svojstvo samo po sebi. Za svaku tehnologiju koja posjeduje mrežni efekt, to je daleko najvažnije svojstvo koje može imati.
Za Bitcoin, mrežni efekt uključuje likvidnost njegovog tržišta, broj ljudi koji ga posjeduju, i zajednicu programera koji održavaju i unaprjeđuju njegov softver i svjesnost u javnosti. Veliki ulagači, uključujući države, će uvijek prvo tražiti najlikvidnije tržište, kako bi mogli ući i izaći iz tržišta brzo, i bez utjecanja na cijenu. Programeri će se pridružiti dominantnoj programerskoj zajednici sa najboljim talentom, i time pojačati samu zajednicu. Svjesnost o brendu sama sebe pojačava, pošto se nadobudni konkurenti Bitcoina uvijek spominju u kontekstu Bitcoina kao takvog.
Raskrižje na putu (fork)
Trend koji je postao popularan 2017. godine nije bio samo imitacija Bitcoinovog softvera, nego kopiranje potpune povijesti njegovih prošlih transakcija (cijeli blockchain). Kopiranjem Bitcoinovog blockchaina do određene točke/bloka i odvajanjem sljedećih blokova ka novoj mreži, u procesu znanom kao “forking” (odvajanje), Bitcoinovi konkurenti su uspjeli riješiti problem distribuiranja svojeg tokena velikom broju korisnika.
Najznačajniji takav fork dogodio se 1. 8. 2017. godine, kada je nova mreža nazvana Bitcoin Cash (Bcash) stvorena. Vlasnik N količine bitcoina prije 1.8.2017. bi onda posjedovao N bitcoina i N BCash tokena. Mala, ali vrlo glasna zajednica Bcash proponenata je neumorno pokušavala prisvojiti Bitcoinov brend i ime, imenujući svoju novu mrežu Bitcoin Cast i pokušavajući uvjeriti nove pridošlice u Bitcoin da je Bcash “pravi” Bitcoin. Ti pokušaji su većinom propali, i taj neuspjeh se vidi u tržišnim kapitalizacijama dviju mreža. No, za nove ulagače, i dalje postoji rizik da bi konkurent mogao kopirati Bitcoin i njegov blockchain i tako uspjeti u preuzimanju tržišne kapitalizacije, te postati de facto Bitcoin.
Moguće je uočiti važno pravilo gledajući velike forkove u prošlosti Bitcoin i Ethereum mreža. Većina tržišne kapitalizacije odvijat će se na mreži koja zadrži najviši stupanj talenta i aktivnosti u zajednici programera. Premda se na Bitcoin može gledati kao na nov i mlad novac, on je također računalna mreža koja počiva na softveru, kojeg se pak treba održavati i poboljšavati. Kupovina tokena na mreži koja ima malo neiskusnih programera bilo bi kao kupovati kopiju Microsoft Windowsa na kojoj rade lošiji programeri. Jasno je vidljivo iz povijesti forkova koji su se odvili 2017. godine da su najbolji računalni i kriptografski stručnjaci posvećeni razvoju originalnog Bitcoina, a ne nekoj od rastućeg broja imitacija koje su se izrodile iz njega.
Stvarni rizici
Premda su uobičajene kritike upućene Bitconu od strane medija i ekonomske profesije krive i bazirane na netočnom shvaćanju novca, postoje pravi i značajni rizici kod ulaganja u Bitcoin. Bilo bi mudro za novog Bitcoin ulagača da shvati ove rizike prije potencijalnog ulaganja.
Rizik protokola
Bitcoin protokol i kriptografski sastavni dijelovi na kojima je sagrađen potencijalno imaju dosad nepronađenu grešku u svom dizajnu, ili mogu postati nesigurni razvojem kvantnih računala. Ako se pronađe greška u protokolu, ili neka nova metoda računarstva učini mogućim probijanje kriptografskih temelja Bitcoina, vjera u Bitcoin biti će znatno narušena. Rizik protokola bio je najviši u ranim godinama razvoja Bitcoina, kada je još uvijek bilo nejasno, čak i iskusnim kriptografima, je li Satoshi Nakamoto zaista riješio problem bizantskih generala (Byzantine Generals’ Problem). Brige oko ozbiljnih grešaka u Bitcoin protokolu nestale su kroz godine, no uzevši u obzir njegovu tehnološku prirodu, rizik protokola će uvijek ostati u Bitcoinu, makar i kao izuzetak.
Propadanje mjenjačnica
Time što je decentraliziran, Bitcoin je pokazao značajnu otpornost, suočen sa brojnim pokušajima raznih vlada da ga reguliraju ili unište. No, mjenjačnice koje trguju bitcoinima za fiat valute su centralizirani entiteti i podložne regulacijama i zatvaranju. Bez mjenjačnica i volje bankara da s njima posluju, proces monetizacije Bitcoina bio bi ozbiljno usporen, ako ne i potpuno zaustavljen. Iako postoje alternativni izvori likvidnosti za Bitcoin, poput “over-the-counter” brokera i decentraliziranih tržišta za kupovinu i prodaju bitcoina, kritičan proces otkrivanja i definiranja cijene se odvija na najlikvidnijim mjenjačnicama, koje su sve centralizirane.
Jedan od načina za umanjivanje rizika gašenja mjenjačnica je geografska arbitraža. Binance, jedna od velikih mjenjačnica iz Kine, preselila se u Japan nakon što joj je kineska vlada zabranila operiranje u Kini. Vlade su također oprezne kako ne bi ugušile novu industriju koja je potencijalno značajna kao i internet, i time predale nevjerojatnu konkurentnu vrijednost drugim nacijama.
Samo kroz koordinirano globalno ukidanje Bitcoin mjenjačnica bi proces monetizacije mogao biti zaustavljen. Trenutno smo u utrci; Bitcoin raste i postaje sve rašireniji, i doći će do trenutka kada bi potpuno ukidanje mjenjačnica postalo politički neizvedivo - kao i gašenje interneta. Mogućnost takvog ukidanja je još uvijek realna, i valja je uzeti u obzir pri ulaganju u Bitcoin. Kao što je gore objašnjeno, suverene vlade se polako bude i uviđaju prijetnju koju predstavlja neovisna digitalna valuta otporna na cenzuru, za njihovu monetarnu politiku. Otvoreno je pitanje hoće li išta poduzeti da odgovore ovoj prijetnji prije nego Bitcoin postane toliko utvrđen i raširen da politička akcija postane nemoćna i ne-efektivna.
Zamjenjivost
Otvorena i transparentna priroda Bitcoin blockchaina omogućava državama da proglase specifične bitcoine “okaljanima” zbog njihovog korištenja u određenim aktivnostima. Premda Bitcoin, na protokolarnoj razini, ne diskriminira transakcije na ikoji način, “okaljani” bitcoini bi mogli postati bezvrijedni ako bi ih regulacije proglasile ilegalnima i neprihvatljivima za mjenjačnice ili trgovce. Bitcoin bi tada izgubio jedno od kritičnih svojstava monetarnog dobra: zamjenjivost.
Da bi se ovaj problem riješio i umanjio, biti će potrebna poboljšanja na razini protokola kako bi se poboljšala privatnost transakcija. Premda postoji napredak u ovom smjeru, prvi put primjenjen u digitalnim valutama kao što su Monero i Zcash, potrebno je napraviti značajne tehnološke kompromise između efikasnosti i kompleksnosti Bitcoina i njegove privatnosti. Pitanje ostaje otvoreno je li moguće dodati nova svojstva privatnosti na Bitcoin, na način koji neće kompromitirati njegovu korisnost kao novca.
Zaključak
Bitcoin je novonastali novac koji je u procesu transformacije iz sakupljačkog dobra u spremište vrijednosti. Kao neovisno monetarno dobro, moguće je da će u budućnosti postati globalan novac, slično kao zlato za vrijeme 19. stoljeća. Prihvaćanje Bitcoina kao globalnog novca je upravo taj optimističan scenarij za Bitcoin, kojeg je artikulirao Satoshi Nakamoto još 2010. godine u email razmjeni sa Mikeom Hearnom:
"Ako zamisliš da se koristi u nekom dijelu svjetske trgovine, i da će postojati samo 21 milijun bitcoina za cijeli svijet, vrijednost po jedinici će biti znatno veća".
Ovaj scenarij je još snažnije definirao briljantni kriptograf Hal Finney, koji je ujedno primio i prve bitcoine od Nakamotoa, ubrzo nakon najave prvog funkcionalnog Bitcoin softvera:
"Zamislimo da Bitcoin bude uspješan i postane dominantan sustav plaćanja diljem svijeta. U tom slučaju će ukupna vrijednost valute biti jednaka ukupnoj vrijednosti svog bogatstva svijeta. Današnje procjene ukupnog svjetskog bogatska kućanstava koje sam pronašao borave negdje između 100 i 300 trilijuna dolara. Sa 20 milijuna bitcoina, svaki bi onda vrijedio oko 10 milijuna dolara."
Čak i da Bitcoin ne postane u cijelost globalan novac, nego da se samo natječe sa zlatom kao neovisno spremište vrijednosti, i dalje je masivno podcijenjen. Mapiranje tržišne kapitalizacije postojeće količine izrudarenog zlata (oko 8 trilijuna dolara) na maksimalnu dostupnost Bitcoina od 21 milijun, daje vrijednost od otprilike 380,000 dolara po bitcoinu. Kao što smo vidjeli u prethodnom tekstu, svojstva koja omogućavaju monetarnom dobru da bude prikladno spremište vrijednosti, čine Bitcoin superiornijim zlatu u svakom pogledu osim trajanja povijesti. No, kako vrijeme prolazi i Lindy efekt postane jači, dosadašnja povijest će prestati biti prednost zlata. Samim time, nije nerazumno očekivati da će Bitcoin narasti do, a možda i preko, ukupne cijene zlata na tržištvu do 2030. Opaska ovoj tezi je činjenica da veliki postotak vrijednosti zlata dolazi od toga što ga centralne banke čuvaju kao spremište vrijednosti. Da bi Bitcoin došao do te razine, određena količina suverenih država će trebati sudjelovati. Hoće li zapadnjačke demokracije sudjelovati u vlasništvu Bitcoina je nepoznato. Vjerojatnije je, nažalost, da će prve nacije u Bitcoin tržištu biti sitne diktature i kleptokracije.
Ako niti jedna država ne bude sudjelovala u Bitcoin tržištu, optimistična teza i dalje postoji. Kao nevisno spremište vrijednosti u rukama individualnih i institucionalnih ulagača, Bitcoin je i dalje vrlo rano u svojoj “krivulji prihvaćenosti” (adoption curve); tzv. “rana većina” ulaze na tržište sada, dok će ostali ući tek nekoliko godina kasnije. Sa širim sudjelovanjem individualnih i institucionalnih ulagača, cijena po bitcoinu između 100,000 i 200,000 dolara je sasvim moguća.
Posjedovanje bitcoina je jedna od malobrojnih asimetričnih novčanih strategija dostupnih svakome na svijetu. Poput “call” opcija, negativan rizik ulagača je ograničen na 1x, dok potencijalna dobit i dalje iznosi 100x ili više. Bitcoin je prvi istinski globalan balon čija je veličina ograničena samo potražnjom i željom građana svijeta da zaštite svoju ušteđevinu od raznovrsnih ekonomskih malverzacija vlade. Bitcoin je ustao kao feniks iz pepela globalne financijske krize 2008. godine - katastrofe kojoj su prethodile odluke centralnih banaka poput američke Federalne rezerve (Federal Reserve).
Onkraj samo financijske teze za Bitcoin, njegov rast i uspjeh kao neovisno spremište vrijednosti imat će duboke geopolitičke posljedice. Globalna, ne-inflacijska valuta će prisiliti suverene države da promjene svoje primarne mehanizme financiranja od inflacije u izravno oporezivanje; koje je daleko manje politički popularno. Države će se smanjivati proporcionalno političkoj boli koju im nanese oporezivanje kao jedini način financiranja. Nadalje, globalna trgovina vršiti će se na način koji zadovoljava aspiraciju Charlesa de Gaullea, da nijedna nacija ne bi smjela imati privilegiju nad ikojom drugom:
"Smatramo da je potrebno da se uspostavi međunarodna trgovina, kao što je bio slučaj prije velikih nesreća koje su zadesile svijet, na neosporivoj monetarnoj bazi, koja ne nosi na sebi oznaku ijedne države."
Za 50 godina, ta monetarna baza biti će Bitcoin.

There's been a lot of discussion this week about Casey Means being nominated for Surgeon General of the United States and a broader overarching conversation about the effectiveness of MAHA since the inauguration and how effective it may or may not be moving forward. Many would say that President Trump won re-election due to Robert F. Kennedy Jr. and Nicole Shanahan deciding to reach across the aisle and join the Trump ticket, bringing with them the MAHA Moms, who are very focused on reorienting the healthcare system in the United States with a strong focus on the childhood vaccine schedule.
I'm not going to lie, this is something I'm passionate about as well, particularly after having many conversations over the years with doctors like Kevin McKernan, Dr. Jack Kruse, Dr. Mary Talley Bowden, Dr. Brooke Miller, Dr. Peter McCullough and others about the dangers of the COVID mRNA vaccines. As it stands today, I think this is the biggest elephant in the room in the world of healthcare. If you look at the data, particularly disability claims, life insurance claims, life expectancy, miscarriage rates, fertility issues and rates of turbo cancer around the world since the COVID vaccine was introduced in 2021, it seems pretty clear that there is harm being done to many of the people who have taken them.
The risk-reward ratio of the vaccines seems to be incredibly skewed towards risk over reward and children - who have proven to be least susceptible to COVID - are expected to get three COVID shots in the first year of their life if their parents follow the vaccine schedule. For some reason or another it seems that Robert F. Kennedy Jr. has shied away from this topic after becoming the head of Health and Human Services within the Trump administration. This is after a multi-year campaign during which getting the vaccines removed from the market war a core part of his platform messaging.
I'm still holding out hope that sanity will prevail. The COVID mRNA vaccines will be taken off the market in a serious conversation about the crimes against humanity that unfolded during the COVID years will take place. However, we cannot depend on that outcome. We must build with the assumption in mind that that outcome may never materialize. This leads to identifying where the incentives within the system are misconstrued. One area where I think it's pretty safe to say that the incentives are misaligned is the fact that 95% of doctors work for and answer to a corporation driven by their bottom line. Instead of listening to their patients and truly caring about the outcome of each individual, doctors forced to think about the monetary outcome of the corporation they work for first.
The most pernicious way in which these misaligned incentives emerge is the way in which the hospital systems and physicians are monetarily incentivized by big pharma companies to push the COVID vaccine and other vaccines on their patients. It is important to acknowledge that we cannot be dependent on a system designed in this way to change from within. Instead, we must build a new incentive system and market structure. And obviously, if you're reading this newsletter, you know that I believe that bitcoin will play a pivotal role in realigning incentives across every industry. Healthcare just being one of them.
Bitcoiners have identified the need to become sovereign in our monetary matters, it probably makes sense to become sovereign when it comes to our healthcare as well. This means finding doctors who operate outside the corporate controlled system and are able to offer services that align incentives with the end patient. My family utilizes a combination of CrowdHealth and a private care physician to align incentives. We've even utilized a private care physician who allowed us to pay in Bitcoin for her services for a number of years. I think this is the model. Doctors accepting hard censorship resistant money for the healthcare and advice they provide. Instead of working for a corporation looking to push pharmaceutical products on their patients so they can bolster their bottom line, work directly with patients who will pay in bitcoin, which will appreciate in value over time.
I had a lengthy discussion with Dr. Jack Kruse on the podcast earlier today discussing these topic and more. It will be released on Thursday and I highly recommend you freaks check it out once it is published. Make sure you subscribe so you don't miss it.
How the "Exorbitant Privilege" of the Dollar is Undermining Our Manufacturing Base
In my conversation with Lyn Alden, we explored America's fundamental economic contradiction. As Lyn expertly explained, maintaining the dollar's reserve currency status while attempting to reshore manufacturing presents a near-impossible challenge - what economists call Triffin's Dilemma. The world's appetite for dollars gives Americans tremendous purchasing power but simultaneously hollows out our industrial base. The overvalued dollar makes our exports less competitive, especially for lower-margin manufacturing, while our imports remain artificially strong.
"Having the reserve currency does come with a bunch of benefits, historically called an exorbitant privilege, but then it has certain costs to maintain it." - Lyn Alden
This dilemma forces America to run persistent trade deficits, as this is how dollars flow to the world. For over four decades, these deficits have accumulated, creating massive economic imbalances that can't be quickly reversed. The Trump administration's attempts to address this through tariffs showcase how difficult rebalancing has become. As Lyn warned, even if we successfully pivot toward reshoring manufacturing, we'll face difficult trade-offs: potentially giving up some reserve currency benefits to rebuild our industrial foundation. This isn't just economic theory - it's the restructuring challenge that will define America's economic future.
Check out the full podcast here for more on China's manufacturing dominance, the role of Bitcoin in monetary transitions, and energy production as the foundation for future industrial power.

2025-05-20 15:53:48This piece is the first in a series that will focus on things I think are a priority if your focus is similar to mine: building a strong family and safeguarding their future.
Choosing the ideal place to raise a family is one of the most significant decisions you will ever make. For simplicity sake I will break down my thought process into key factors: strong property rights, the ability to grow your own food, access to fresh water, the freedom to own and train with guns, and a dependable community.
A Jurisdiction with Strong Property Rights
Strong property rights are essential and allow you to build on a solid foundation that is less likely to break underneath you. Regions with a history of limited government and clear legal protections for landowners are ideal. Personally I think the US is the single best option globally, but within the US there is a wide difference between which state you choose. Choose carefully and thoughtfully, think long term. Obviously if you are not American this is not a realistic option for you, there are other solid options available especially if your family has mobility. I understand many do not have this capability to easily move, consider that your first priority, making movement and jurisdiction choice possible in the first place.
Abundant Access to Fresh Water
Water is life. I cannot overstate the importance of living somewhere with reliable, clean, and abundant freshwater. Some regions face water scarcity or heavy regulations on usage, so prioritizing a place where water is plentiful and your rights to it are protected is critical. Ideally you should have well access so you are not tied to municipal water supplies. In times of crisis or chaos well water cannot be easily shutoff or disrupted. If you live in an area that is drought prone, you are one drought away from societal chaos. Not enough people appreciate this simple fact.
Grow Your Own Food
A location with fertile soil, a favorable climate, and enough space for a small homestead or at the very least a garden is key. In stable times, a small homestead provides good food and important education for your family. In times of chaos your family being able to grow and raise healthy food provides a level of self sufficiency that many others will lack. Look for areas with minimal restrictions, good weather, and a culture that supports local farming.
Guns
The ability to defend your family is fundamental. A location where you can legally and easily own guns is a must. Look for places with a strong gun culture and a political history of protecting those rights. Owning one or two guns is not enough and without proper training they will be a liability rather than a benefit. Get comfortable and proficient. Never stop improving your skills. If the time comes that you must use a gun to defend your family, the skills must be instinct. Practice. Practice. Practice.
A Strong Community You Can Depend On
No one thrives alone. A ride or die community that rallies together in tough times is invaluable. Seek out a place where people know their neighbors, share similar values, and are quick to lend a hand. Lead by example and become a good neighbor, people will naturally respond in kind. Small towns are ideal, if possible, but living outside of a major city can be a solid balance in terms of work opportunities and family security.
Let me know if you found this helpful. My plan is to break down how I think about these five key subjects in future posts.

2025-05-22 11:50:08ビットコインピザデーということで ビットコインピザを作りました せっかくなので日本っぽい明太ピザにして ビットコインロゴは鮭のテリーヌにしました
鮭のテリーヌ
はんぺんでBのマークを気合で切ります 色付きクリアファイルをBマークに切って乗せると楽です 鮭とはんぺんと牛乳と卵と塩をフードプロセッサーにかけます 容器に流して蒸し焼きします
生地作り
強力粉・ドライイースト・塩・オリーブオイル・水を混ぜます 気合でこねます 1時間くらい発酵させるとふっくらします
トッピングの明太マヨ
明太子とマヨネーズとしょうゆを混ぜます
のばした生地に 明太マヨ・チーズ・コーンを乗せて焼きます 途中で薄いおもちを乗せます 焼けたらのりとテリーヌを乗せてできあがり
反省点いろいろ
今回一番くやしいのは明太マヨに色がつきすぎたこと 明太ピザってピンク色の感じが独特な気がするし もしかしたら日本だけかもと思ったから作ったのに 焼けたらトマトソースみたいな色になっちゃった なんてことだ 生地に焼き色がつかないな~白いな~もうちょっと焼くか~とか思ってたら 明太さんが焦げてました むねん
ちなみに製作動画の中でテリーヌを2つに分けているのは 鮭とはんぺんの部分が同じ色っぽくなってBが目立たなかったらどうしようと思って 片方はケチャップを足して 赤色濃くなるかな~大失敗したらいやだな~とか思ってたんですけど ケチャップ入れても何も変わらなかった むねん
薄いおもち(しゃぶしゃぶもちというらしい)を買ってしまったんだけど これはピザのトッピングにするには焦げそうだから 普通の厚みのもちの方がよさそう 今回は途中で一度オーブン開けておもちを乗せたけど オーブンの温度が下がるのが微妙かも
あと今回は練習無しのぶっつけ本番で作ったので ちょっと自分の中で反省点が多かったな~と やっぱり一度試作した方がいいですね いや鮭とか明太子とか高くて(言い訳
あ~あとチーズ 溶け溶けチーズがのびーるインスタ映え的なやつをやりたかったんですけど 全然むりでした のびないのびない ああいうのは別で工夫が必要そうなので要検討
味はおいしかったです 明太マヨって自分ではあんまり食べないしピザはマルゲリータ派なんですけど結構いいですね ちょっと味が濃くてご飯食べたくなっちゃった 次作る時はしょうゆ入れないようにしよう

2025-05-28 19:01:49Marty's Bent
Last week we covered the bombshell developments in the Samourai Wallet case. For those who didn't read that, last Monday the world was made aware of the fact that the SDNY was explicitly told by FinCEN that the federal regulator did not believe that Samourai Wallet was a money services business six months before arresting the co-founders of Samourai Wallet for conspiracy to launder money and illegally operating a money services business. This was an obvious overstep by the SDNY that many believed would be quickly alleviated, especially considering the fact that the Trump administration via the Department of Justice has made it clear that they do not intend to rule via prosecution.
It seems that this is not the case as the SDNY responded to a letter sent from the defense to dismiss the case by stating that they fully plan to move forward. Stating that they only sought the recommendations of FinCEN employees and did not believe that those employees' comments were indicative of FinCEN's overall views on this particular case. It's a pretty egregious abuse of power by the SDNY. I'm not sure if the particular lawyers and judges within the Southern District of New York are very passionate about preventing the use of self-custody bitcoin and products that enable bitcoiners to transact privately, or if they're simply participating in a broader meta war with the Trump administration - who has made it clear to federal judges across the country that last Fall's election will have consequences, mainly that the Executive Branch will try to effectuate the policies that President Trump campaigned on by any legal means necessary - and Samouari Wallet is simply in the middle of that meta war.
However, one thing is pretty clear to me, this is an egregious overstep of power. The interpretation of that law, as has been laid out and confirmed by FinCEN over the last decade, is pretty clear; you cannot be a money services business if you do not control the funds that people are sending to each other, which is definitely the case with Samourai Wallet. People downloaded Samourai Wallet, spun up their own private-public key pairs and initiated transactions themselves. Samourai never custodied funds or initiated transactions on behalf of their users. This is very cut and dry. Straight to the point. It should be something that anyone with more than two brain cells is able to discern pretty quickly.
It is imperative that anybody in the industry who cares about being able to hold bitcoin in self-custody, to mine bitcoin, and to send bitcoin in a peer-to-peer fashion makes some noise around this case. None of the current administration's attempts to foster innovation around bitcoin in the United States will matter if the wrong precedent is set in this case. If the SDNY is successful in prosecuting Samourai Wallet, it will mean that anybody holding Bitcoin in self-custody, running a bitcoin fold node or mining bitcoin will have to KYC all of their users and counterparts lest they be labeled a money services business that is breaking laws stemming from the Bank Secrecy Act. This will effectively make building a self-custody bitcoin wallet, running a node, or mining bitcoin in tillegal in the United States. The ability to comply with the rules that would be unleashed if this Samourai case goes the wrong way, are such that it will effectively destroy the industry overnight.
It is yet to be seen whether or not the Department of Justice will step in to publicly flog the SDNY and force them to stop pursuing this case. This is the only likely way that the case will go away at this point, so it is very important that bitcoiners who care about being able to self-custody bitcoin, mine bitcoin, or send bitcoin in a peer-to-peer fashion in the United States make it clear to the current administration and any local politicians that this is an issue that you care deeply about. If we are too complacent, there is a chance that the SDNY could completely annihilate the bitcoin industry in America despite of all of the positive momentum we're seeing from all angles at the moment.
Bitcoin Adoption by Power Companies: The Next Frontier
In my recent conversation with Andrew Myers from Satoshi Energy, he shared their ambitious mission to "enable every electric power company to use bitcoin by block 1,050,000" – roughly three years from now. This strategic imperative isn't just about creating new Bitcoin users; it's about sovereignty. Andrew emphasized that getting Bitcoin into the hands of energy companies who value self-sovereignty creates a more balanced future economic landscape. The excitement was palpable as he described how several energy companies are already moving beyond simply selling power to Bitcoin miners and are beginning to invest in mining operations themselves.
"You have global commodity companies being like, 'Oh, this is another commodity – we want to invest in this, we want to own this,'" - Andrew Myers
Perhaps most fascinating was Andrew's revelation about major energy companies in Texas developing Bitcoin collateral products for power contracts – a practical application that could revolutionize how energy transactions are settled. As energy companies continue embracing Bitcoin for both operations and collateral, we're witnessing the early stages of a profound shift in how critical infrastructure interfaces with sound money. The implications for both sectors could be transformative.

2025-05-28 19:01:46Key Takeaways
In this episode of TFTC, energy economist Anas Alhajji outlines a profound shift in U.S. foreign policy under Trump—away from military intervention and toward transactional diplomacy focused on trade, reconstruction, and curbing Chinese and Russian influence in the Middle East. He highlights Trump’s quiet outreach to Syria as emblematic of the U.S.'s strategic flexibility in legitimizing former adversaries when economically beneficial. Alhajji dismisses BRICS as a fractured bloc incapable of rivaling the U.S.-led order and insists the dollar and petrodollar remain dominant. On energy, he warns that despite favorable fundamentals, prices are suppressed by political confusion, underinvestment, and an aging power grid ill-prepared for the AI and urbanization boom. He also contends that Iran is stalling negotiations to buy time for nuclear advancement and that any deal will be superficial. Finally, Alhajji debunks the myth of Trump being pro-oil, noting his long-standing hostility toward the industry and explaining why a repeat of his past energy boom is implausible given today’s financial and structural constraints.
Best Quotes
- “BRICS is a paper tiger. Everything about BRICS is what China does—and that’s it.”
- “The dollar is here to stay. The petrodollar is here to stay. End of story.”
- “Trump hates the oil industry. He always classified it as an enemy.”
- “Energy projects are 30- to 40-year investments, but politicians think in 4-year cycles. That’s where the disconnect lies.”
- “People think shale will boom again. It won’t. The model changed from ‘drill baby drill’ to ‘control baby control.’”
- “The real story of Trump’s trip wasn’t about politics—it was investment, investment, investment.”
- “Without massive investment in the grid and gas turbines, blackouts will become the norm—even in rich countries like Kuwait.”
- “Iran and China have perfected the game of oil exports. Sanctions are just theater at this point.”
Conclusion
Anas Alhajji’s conclusion challenges conventional narratives, arguing that global power is shifting from military dominance to economic leverage, infrastructure investment, and energy control. He presents a nuanced view of U.S. foreign policy under Trump, emphasizing the strategic importance of trade and reconstruction over regime change. As energy demand soars and geopolitical risks mount, Alhajji warns that the real dangers lie not in foreign adversaries, but in policy confusion, infrastructural lag, and complacency—making this episode a crucial listen for anyone seeking to understand the high-stakes intersection of energy, economics, and diplomacy.

(00:00) oil prices market fundamentals support higher price than where we are today. But because of this confusion, everyone is scared of low economic growth and that is a serious problem. The US media ignored part of Trump's speech when he said we are not about nation building and they refer to Afghanistan and Iraq.
(00:15) Look at them. This is a criticism of George W. Bush. We have groups that are talking about the demise of the dollar, the rise of bricks. Bricks is a paper tiger. Everything about bricks is what China does and that's it. The dollar is here to stay and the petro dollar is here to stay.
(00:31) The perception is that the Trump administration is cold but the reality Trump hates the oil [Music] indust. How are you? Very good. Very good. Thank you. As you were telling me, you've been a bit sleepd deprived this week trying to keep up with what's going on. Oh, absolutely. I mean, Trump keeps us on our toes uh all the time.
(01:06) In fact, I plan certain things for the weekend and Trump will say something or he will do something and all of a sudden we get busy again. Uh so clients are not going to wait for you until you finish your work. Basically, they want to know what's going on. So what is going on? What what how profound were the events in the Middle East? These are very uh very profound changes basically because it is very clear that if you look at the last 15 years uh and you look at the growth uh in the Middle East, you look at the growth of Saudi Arabia and uh the
(01:41) role of Turkey for example in the region uh it just just amazing be beyond any uh any thoughts. Uh in fact both of them Turkey and Saudi Arabia are part of the G20. Uh so they have economic influence and they have political influence. And of course the icing on the cake for those who are familiar with the region is to recognize the Syrian government and meet with the Syrian uh president.
(02:11) Uh this is a major a major change in economics and politics uh of the Middle East. Let's touch on that Syria uh topic for a while because I think a lot of people here in the United States were a bit shocked at how sort of welcoming President Trump was towards the new Syrian president considering the fact that uh he was considered an enemy not too long ago here in the United States.
(02:42) What first of all it's a fact of life for those who would like to check the history of politics. There were many people around the world who were classified or they were on the terrorism list and then they became friends of the United States or they were became heroes. I mean Nelson Mandela is one of them. You look at Latin America, there are presidents in Latin America who were uh the enemy of the United States and then they became uh uh cooperative with the United States and the United States recognized their governments and the result of their uh elections. Uh so
(03:15) we've seen this historically uh several uh several times around the world and as they say freedom fighters for some basically are the enemies and the terrorists for for others etc. So uh what we've seen that's why the the visit is very important that the recognition of this government is very important. uh the fact on the ground that uh the president of Syria had the power on the ground uh he had the the the people on the ground and he had the control on the ground and whatever he's been he's been doing since he came into power until now
(03:52) he done all the right steps u and people loved him I mean everyone who went to Syria whether the Syrians who left Syria 40 years ago or uh the visitors who are coming to Syria, they will tell you, "We have never seen the Syrian people as happy as we've seen them today, despite the fact that they they live in misery.
(04:17) They don't have um 8 million people without housing. Uh there is barely any electricity in most of the country. There is no internet. There is barely any food. The uh inflation is rampant, etc. But people are happy because they lived in fear for a very long time. And uh the steps they have taken. For example, the uh ministers in the previous government uh are still there and they are still in the housing of the government.
(04:49) They still have the drivers. They still have the cars from the previous government. They still have it until today. So uh they they were classified as enemies before. But all of a sudden now you have a new government that is uh accepting them. Uh so we we see some changes on the ground that are positive and we'll see how these things will go given that the area around them basically has been unstable for a very long time.
(05:17) how because I don't the the news when I was actually it was surreal for me because my first trip to the Middle East was last December when it was literally f flying over Syria to Abu Dhabi when uh um Assad was getting thrown out and it was pretty surreal to be in that region of the world.
(05:43) How as it pertains to like religious minorities within Syria moving forward is there protractions protections there? Um well let me just uh I want to emphasize one point that is very important. What did the interest of Turkey, Saudi Arabia and the United States in Syria if remember Syria was controlled by Iran and was controlled by the Russians.
(06:09) So in a sense it becomes uh kind of an imperative that taking it away from Iran and Russia and not bringing Iran or Russia back is extremely important. Now the Russians are still there and they have their own base but at least they are not bombing the Syrians and not killing them anymore. But the idea here is taking Syria out of Iran and Russia and probably later on if they kick the Russians out, Russians will not have access to the Mediterranean.
(06:37) Uh so there is an interest uh of all parties basically to take Russia out of Iran and um out of uh Syria regardless the country is uh devastated and it creates massive opportunities for US companies on all levels and uh we've seen a contract uh done recently with you mentioned Abu Dhabi uh uh a contract uh uh with the UA a basically to revamp all the Syrian ports and work on the Syrian ports.
(07:13) Uh so such contracts basically uh when you have a country that has nothing and it's completely devastated the whole infrastructure is devastated. Who is going to build it? If the uh what the Chinese, the Russians, so who who are going to build it? So, uh I think there is a a big room for US companies and others basically to come in and uh literally help on one side and make money on the other.
(07:38) Yeah, I think that that's what I'm trying to discern. What was this convoy from the United States to the Middle East this week signali -

2025-05-20 15:47:16Here’s a revised timeline of macro-level events from The Mandibles: A Family, 2029–2047 by Lionel Shriver, reimagined in a world where Bitcoin is adopted as a widely accepted form of money, altering the original narrative’s assumptions about currency collapse and economic control. In Shriver’s original story, the failure of Bitcoin is assumed amid the dominance of the bancor and the dollar’s collapse. Here, Bitcoin’s success reshapes the economic and societal trajectory, decentralizing power and challenging state-driven outcomes.
Part One: 2029–2032
-
2029 (Early Year)\ The United States faces economic strain as the dollar weakens against global shifts. However, Bitcoin, having gained traction emerges as a viable alternative. Unlike the original timeline, the bancor—a supranational currency backed by a coalition of nations—struggles to gain footing as Bitcoin’s decentralized adoption grows among individuals and businesses worldwide, undermining both the dollar and the bancor.
-
2029 (Mid-Year: The Great Renunciation)\ Treasury bonds lose value, and the government bans Bitcoin, labeling it a threat to sovereignty (mirroring the original bancor ban). However, a Bitcoin ban proves unenforceable—its decentralized nature thwarts confiscation efforts, unlike gold in the original story. Hyperinflation hits the dollar as the U.S. prints money, but Bitcoin’s fixed supply shields adopters from currency devaluation, creating a dual-economy split: dollar users suffer, while Bitcoin users thrive.
-
2029 (Late Year)\ Dollar-based inflation soars, emptying stores of goods priced in fiat currency. Meanwhile, Bitcoin transactions flourish in underground and online markets, stabilizing trade for those plugged into the bitcoin ecosystem. Traditional supply chains falter, but peer-to-peer Bitcoin networks enable local and international exchange, reducing scarcity for early adopters. The government’s gold confiscation fails to bolster the dollar, as Bitcoin’s rise renders gold less relevant.
-
2030–2031\ Crime spikes in dollar-dependent urban areas, but Bitcoin-friendly regions see less chaos, as digital wallets and smart contracts facilitate secure trade. The U.S. government doubles down on surveillance to crack down on bitcoin use. A cultural divide deepens: centralized authority weakens in Bitcoin-adopting communities, while dollar zones descend into lawlessness.
-
2032\ By this point, Bitcoin is de facto legal tender in parts of the U.S. and globally, especially in tech-savvy or libertarian-leaning regions. The federal government’s grip slips as tax collection in dollars plummets—Bitcoin’s traceability is low, and citizens evade fiat-based levies. Rural and urban Bitcoin hubs emerge, while the dollar economy remains fractured.
Time Jump: 2032–2047
- Over 15 years, Bitcoin solidifies as a global reserve currency, eroding centralized control. The U.S. government adapts, grudgingly integrating bitcoin into policy, though regional autonomy grows as Bitcoin empowers local economies.
Part Two: 2047
-
2047 (Early Year)\ The U.S. is a hybrid state: Bitcoin is legal tender alongside a diminished dollar. Taxes are lower, collected in BTC, reducing federal overreach. Bitcoin’s adoption has decentralized power nationwide. The bancor has faded, unable to compete with Bitcoin’s grassroots momentum.
-
2047 (Mid-Year)\ Travel and trade flow freely in Bitcoin zones, with no restrictive checkpoints. The dollar economy lingers in poorer areas, marked by decay, but Bitcoin’s dominance lifts overall prosperity, as its deflationary nature incentivizes saving and investment over consumption. Global supply chains rebound, powered by bitcoin enabled efficiency.
-
2047 (Late Year)\ The U.S. is a patchwork of semi-autonomous zones, united by Bitcoin’s universal acceptance rather than federal control. Resource scarcity persists due to past disruptions, but economic stability is higher than in Shriver’s original dystopia—Bitcoin’s success prevents the authoritarian slide, fostering a freer, if imperfect, society.
Key Differences
- Currency Dynamics: Bitcoin’s triumph prevents the bancor’s dominance and mitigates hyperinflation’s worst effects, offering a lifeline outside state control.
- Government Power: Centralized authority weakens as Bitcoin evades bans and taxation, shifting power to individuals and communities.
- Societal Outcome: Instead of a surveillance state, 2047 sees a decentralized, bitcoin driven world—less oppressive, though still stratified between Bitcoin haves and have-nots.
This reimagining assumes Bitcoin overcomes Shriver’s implied skepticism to become a robust, adopted currency by 2029, fundamentally altering the novel’s bleak trajectory.

2025-05-20 13:49:50I’ve written about MSTR twice already, https://www.chrisliss.com/p/mstr and https://www.chrisliss.com/p/mstr-part-2, but I want to focus on legendary short seller James Chanos’ current trade wherein he buys bitcoin (via ETF) and shorts MSTR, in essence to “be like Mike” Saylor who sells MSTR shares at the market and uses them to add bitcoin to the company’s balance sheet. After all, if it’s good enough for Saylor, why shouldn’t everyone be doing it — shorting a company whose stock price is more than 2x its bitcoin holdings and using the proceeds to buy the bitcoin itself?
Saylor himself has said selling shares at 2x NAV (net asset value) to buy bitcoin is like selling dollars for two dollars each, and Chanos has apparently decided to get in while the getting (market cap more than 2x net asset value) is good. If the price of bitcoin moons, sending MSTR’s shares up, you are more than hedged in that event, too. At least that’s the theory.
The problem with this bet against MSTR’s mNAV, i.e., you are betting MSTR’s market cap will converge 1:1 toward its NAV in the short and medium term is this trade does not exist in a vacuum. Saylor has described how his ATM’s (at the market) sales of shares are accretive in BTC per share because of this very premium they carry. Yes, we’ll dilute your shares of the company, but because we’re getting you 2x the bitcoin per share, you are getting an ever smaller slice of an ever bigger overall pie, and the pie is growing 2x faster than your slice is reducing. (I https://www.chrisliss.com/p/mstr how this works in my first post.)
But for this accretion to continue, there must be a constant supply of “greater fools” to pony up for the infinitely printable shares which contain only half their value in underlying bitcoin. Yes, those shares will continue to accrete more BTC per share, but only if there are more fools willing to make this trade in the future. So will there be a constant supply of such “fools” to keep fueling MSTR’s mNAV multiple indefinitely?
Yes, there will be in my opinion because you have to look at the trade from the prospective fools’ perspective. Those “fools” are not trading bitcoin for MSTR, they are trading their dollars, selling other equities to raise them maybe, but in the end it’s a dollars for shares trade. They are not selling bitcoin for them.
You might object that those same dollars could buy bitcoin instead, so they are surely trading the opportunity cost of buying bitcoin for them, but if only 5-10 percent of the market (or less) is buying bitcoin itself, the bucket in which which those “fools” reside is the entire non-bitcoin-buying equity market. (And this is not considering the even larger debt market which Saylor has yet to tap in earnest.)
So for those 90-95 percent who do not and are not presently planning to own bitcoin itself, is buying MSTR a fool’s errand, so to speak? Not remotely. If MSTR shares are infinitely printable ATM, they are still less so than the dollar and other fiat currencies. And MSTR shares are backed 2:1 by bitcoin itself, while the fiat currencies are backed by absolutely nothing. So if you hold dollars or euros, trading them for MSTR shares is an errand more sage than foolish.
That’s why this trade (buying BTC and shorting MSTR) is so dangerous. Not only are there many people who won’t buy BTC buying MSTR, there are many funds and other investment entities who are only able to buy MSTR.
Do you want to get BTC at 1:1 with the 5-10 percent or MSTR backed 2:1 with the 90-95 percent. This is a bit like medical tests that have a 95 percent accuracy rate for an asymptomatic disease that only one percent of the population has. If someone tests positive, it’s more likely to be a false one than an indication he has the disease*. The accuracy rate, even at 19:1, is subservient to the size of the respective populations.
At some point this will no longer be the case, but so long as the understanding of bitcoin is not widespread, so long as the dollar is still the unit of account, the “greater fools” buying MSTR are still miles ahead of the greatest fools buying neither, and the stock price and mNAV should only increase.
. . .
One other thought: it’s more work to play defense than offense because the person on offense knows where he’s going, and the defender can only react to him once he moves. Similarly, Saylor by virtue of being the issuer of the shares knows when more will come online while Chanos and other short sellers are borrowing them to sell in reaction to Saylor’s strategy. At any given moment, Saylor can pause anytime, choosing to issue convertible debt or preferred shares with which to buy more bitcoin, and the shorts will not be given advance notice.
If the price runs, and there is no ATM that week because Saylor has stopped on a dime, so to speak, the shorts will be left having to scramble to change directions and buy the shares back to cover. Their momentum might be in the wrong direction, though, and like Allen Iverson breaking ankles with a crossover, Saylor might trigger a massive short squeeze, rocketing the share price ever higher. That’s why he actually welcomes Chanos et al trying this copycat strategy — it becomes the fuel for outsized gains.
For that reason, news that Chanos is shorting MSTR has not shaken my conviction, though there are other more pertinent https://www.chrisliss.com/p/mstr-part-2 with MSTR, of which one should be aware. And as always, do your own due diligence before investing in anything.
* To understand this, consider a population of 100,000, with one percent having a disease. That means 1,000 have it, 99,000 do not. If the test is 95 percent accurate, and everyone is tested, 950 of the 1,000 will test positive (true positives), 50 who have it will test negative (false negatives.) Of the positives, 95 percent of 99,000 (94,050) will test negative (true negatives) and five percent (4,950) will test positive (false positives). That means 4,950 out of 5,900 positives (84%) will be false.

2025-05-19 22:33:33タイトルは釣りです。そんなこと微塵も思っていません。 本稿はアウトボックスモデルの実装に関してうだうだ考えるコーナーです。 ダムスに関して何か言いたいわけではないので先にタイトル回収しておきます。
- NIP-65を守る気なんかさらさら無いのにNIP-65に書いてあるkind:10002のReadリレーの意味を知っていながら全然違う使い方をしているのは一部の和製クライアントの方だよね
- NIP-65を守る気が無いならkind:10002を使うべきではなく、独自仕様でリレーを保存するべきだよね
- アウトボックスモデルを採用しているクライアントからすれば仕様と異なる実装をしてしまっているクライアントが迷惑だと思われても仕方ないよね
- と考えればダムスの方が潔いよね
- とはいえkind:3のcontentは空にしろって言われてんだからやっぱダムスはゴミだわ
- やるとしたらRabbitみたいにローカルに保存するか、別デバイス間で同期したいならkind:30078を使うべきだよね
アウトボックスモデルはなぜ人気がないのか
言ってることはとてもいいと思うんですよ。 欠点があるとすれば、
- 末端のユーザーからすればreadリレーとwriteリレーと書かれると直感的にイメージされるものとかけ離れている
- 正しく設定してもらうには相当の説明が必要
- フォローTLを表示しようとすれば非常にたくさんのリレーと接続することになり現実的ではない
- なるほど完璧な作戦っスねーっ 不可能だという点に目をつぶればよぉ~
余談ですが昔irisでログインした時に localhost のリレーに繋ごうとしてiris壊れたって思ったけど今思えばアウトボックスモデルを忠実に実装してたんじゃないかな…。
現実的に実装する方法は無いのか
これでReadすべきリレーをシミュレーションできる。 https://nikolat.github.io/nostr-relay-trend/ フォローイーのWriteリレーを全部購読しようとすると100個近いリレー数になるので現実的ではありません。 しかしフォローイーのWriteリレーのうち1個だけでよい、とする条件を仮に追加すると一気にハードルが下がります。私の場合はReadリレー含めて7個のリレーに収まりました。 Nos Haikuはとりあえずこの方針でいくことにしました。
今後どうしていきたいのか
エンドユーザーとしての自分の志向としては、自分が指定したリレーだけを購読してほしい、勝手に余計なリレーを読みに行かないでほしい、という気持ちがあり、現状の和製クライアントの仕様を気に入っています。 仮にNos Haikuでアウトボックスモデルを採用しつつ自分の決めたリレーに接続するハイブリッド実装を考えるとすれば、
あなたの購読するリレーはこれですよー - Read(inbox) Relays (あなたへのメンションが届くリレー) - wss://relay1.example.com/ - wss://relay2.example.com/ - wss://relay3.example.com/ - Followee's Write Relays (フォローイーが書き込んでいるリレー) - wss://relay4.example.com/ - wss://relay5.example.com/ - wss://relay6.example.com/って出して、チェックボックス付けてON/OFFできるようにして最終的に購読するリレーをユーザーに決めてもらう感じかな……って漠然と考えています。よほど時間を持て余したときがあればやってみるかも。
あとリレーを数は仕方ないとしてリレーごとにフォローイーの投稿だけを取得するようにした方が理にかなってるよね。全部のリレーから全部のフォローイーの投稿を取得しようとしたら(実装はシンプルで楽だけど)通信量が大変だよね。 rx-nostr の Forward Strategy ってリレーごとにREQかえて一度に購読できるっけ?
常にひとつ以下の REQ サブスクリプションを保持します。
って書いてあるから無理なのかな? あとReadリレーは純粋に自分へのメンション(pタグ付き)イベントのみを購読するようにした方がいい気がする。スパム対策としてかなり有効だと思うので。スパムはNIP-65に準拠したりはしていないでしょうし。 まぁ、NIP-65に準拠していないクライアントからのメンションは届かなくなってしまうわけですが。

Cowbolt Announces Their Mission to Make Bitcoin Familiar to EverybodyToday at the Bitcoin Conference in Las Vegas, Cowbolt, an app that lets you split expense payments and settle in bitcoin, will launch their mission: turn peer-to-peer payments into a Bitcoin onramp, starting with family and friends.
Cowbolt will let their clients split costs and settle instantly using Bitcoin and USDT, with no middlemen, no bank friction and with self-custody. They will try to convert everyday transactions into Bitcoin adoption.
“We believe the most powerful onramp to Bitcoin isn’t an exchange — it’s people,” said the co-founder of Cowbolt Daniel Ekström. “That’s why we built Cowbolt. For friends, not hedge funds.”
What Cowbolt will bring to the table:
- Split and settle.
- Keep your keys.
- Fast and trusted.
- Works across borders.
The app is already being used for remittances, group travel, and day-to-day payments. It’s designed to be like a modern fintech app and will be available for iOS and Android.
“Building Airbnb taught me that when design is simple and gets out of the way, people do amazing things,” stated the ex-Creative Director at Airbnb & co-founder Cowbolt Tony Högqvist. “That’s the point here too. Not to store bitcoin in an ETF, but to use it between people. Effortlessly. Among teams, friends, families — every day.”

2025-05-16 20:52:42Streams are the key to nostr
Loading events from a nostr relay is probably the most inconsistent way of loading data I've had to work with, and that's only loading from a single relay. the problem gets exponentially more complicated once you try to load events from multiple relays
Unlike HTTP nostr does not have a simple flow with timeouts built in. events are sent back one at a time and can fail at any point or have massive (10s) gaps between them
The key is to use streams. something that starts, emits any number of results, then maybe errors or completes. luckily it just so happens that JavaScript / TypeScript has a great observable stream library called RxJS
What is an observable
An
Observable
in RxJS is stream a of data that are initialized lazily, which means the stream is inactive and not running until something subscribes to it```ts let stream = new Observable((observer) => { observer.next(1) observer.next(2) observer.next(3) observer.complete() })
// The stream method isn't run until its subscribed to stream.subscribe(v => console.log(v)) ```
This is super powerful and perfect for nostr because it means we don't need to manage the life-cycle of the stream. it will run when something subscribes to it and stop when unsubscribed.
Its helpful to think of this as "pulling" data. once we have created an observable we can request the data from it at any point in the future.
Pulling data from relays
We can use the lazy nature of observables to only start fetching events from a nostr relay when we need them
For example we can create an observable that will load kind 1 events from the damus relay and stream them back as they are returned from the relay
```typescript let req = new Observable((observer) => { // Create a new websocket connection when the observable is start let ws = new WebSocket('wss://relay.damus.io')
ws.onopen = () => { // Start a REQ ws.send(JSON.stringify(['REQ', 'test', {kinds: [1], limit: 20}])) }
ws.onmessage = (event) => { let message = JSON.parse(event.data) // Get the event from the message and pass it along to the subscribers if(message[0] === 'EVENT') observer.next(message[1]) }
// Cleanup subscription return () => { ws.send(JSON.stringify(['CLOSE', 'test'])) ws.close() } }) ```
But creating the observable wont do anything. we need to subscribe to it to get any events.
ts let sub = req.subscribe(event => { console.log('we got an event' event) })
Cool now we are pulling events from a relay. once we are done we can stop listening to it by unsubscribing from it
ts sub.unsubscribe()
This will call the cleanup method on the observable, which in turn closes the connection to the relay.
Hopefully you can see how this work, we don't have any
open
,connect
, ordisconnect
methods. we simply subscribe to a stream of events and it handles all the messy logic of connecting to a relayComposing and chaining observables
I've shown you how we can create a simple stream of events from a relay, but what if we want to pull from two relays?
Easy, lets make the previous example into a function that takes a relay URL
```ts function getNoteFromRelay(relay: string){ return new Observable((observer) => { let ws = new WebSocket(relay)
// ...rest of the observable...
}) } ```
Then we can "merge" two of these observables into a single observable using the
merge
method from RxJSThe
merge
method will create a single observable that subscribes to both upstream observables and sends all the events back. Think of it as pulling events from both relays at once```ts import { merge } from 'rxjs'
const notes = merge( getNoteFromRelay('wss://relay.damus.io'), getNoteFromRelay('wss://nos.lol') )
// Subscribe to the observable to start getting data from it const sub = notes.subscribe(event => { console.log(event) })
// later unsubscribe setTimeout(() => { sub.unsubscribe() }, 10_000) ```
But now we have a problem, because we are pulling events from two relays we are getting duplicate events. to solve this we can use the
.pipe
method and thedistinct
operator from RxJS to modify our single observable to only return one version of each eventThe
.pipe
method will create a chain of observables that will each subscribe to the previous one and modify the returned values in some wayThe
distinct
operator takes a method that returns a unique identifier and filters out any duplicate values```ts import { merge, distinct } from 'rxjs'
const notes = merge( getNoteFromRelay('wss://relay.damus.io'), getNoteFromRelay('wss://nos.lol') ).pipe( // filter out events we have seen before based on the event id distinct(event => event.id) ) ```
Now we have an observable that when subscribed to will connect to two relays and return a stream of events without duplicates...
As you can see things can start getting complicated fast. but its also very powerful because we aren't managing any life-cycle code, we just subscribe and unsubscribe from an observable
Taking it to an extreme
Hopefully at this point you can see how powerful this is, we can think of almost any data loading pattern as a series of observables that pull data from upstream observables and stream it back to the original subscriber.
Here is a quick sketch of what it could look like to load user profiles. each node is an observable that "pulls" data from its child node ending with the "connect websocket" or "load from database" nodes which do the work of making a relay connection
Conclusion
All this might seem pretty simple and straight forward, but its been a long six month of learning for me. I've had to completely rethink how data and nostr events should be handled in a client and how to avoid screwing up and shooting myself in the foot with these powerful tools.
If you want to give RxJS a try I would encourage you to checkout the nostr sdk I've been building called applesauce
Its uses RxJS for pretty much everything and has the simplest and most flexible relay connection API I've seen so far (mainly no life-cycle management)

White House Executive Director Bo Hines Declares U.S. The Future Global Crypto SuperpowerIn a session at the Bitcoin 2025 Conference this morning titled “_Making America the Global Bitcoin Superpower“_, Bo Hines, White House Executive Director, Tyler Williams, from the US Treasury Department, and moderator Miles Jennings made one thing clear: the United States is going all-in on Bitcoin—and fast.
JUST IN:
President Trump's Executive Director said "Bitcoin is the golden standard."
"We're not gonna sell any Bitcoin that we possible have in the US government, period."

— Bitcoin Magazine (@BitcoinMagazine) May 27, 2025
“We are well on our way to becoming the bitcoin superpower of the world,” said Bo Hines. “This is something that is not partisan. This is a revolution in our financial system.”
Moderator Miles Jennings pointed to key regulatory steps currently in motion. “If the bill becomes law (and I hope it does) we will have quite an active role. The connective tissue between the legacy financial system and bitcoin, stablecoins, and everything else will really be paved with stablecoin legislation,” Jennings said.
Hines emphasized that, “Updating the payment rails is necessary and we are well on our way to achieving that.” He also noted that upcoming market structure legislation will define how intermediaries like exchanges and brokers are regulated and how digital assets are classified—either as securities or commodities.
“We want folks to innovate here,” Hines stressed. “We can’t be fearful of them walking into the SEC and getting a Wells notice before they get on the elevator.” He added that U.S. regulators are now encouraging crypto innovators to return: “Our message to folks who have gone offshore is: welcome home_._”
Williams highlighted that any new laws must reflect the unique architecture of decentralized finance. “Traditional markets are based on a principal-agent model,” he explained. “But crypto moves us toward a principal-to-principal structure.”
He noted that after regulatory support for the ETP marketplace, institutional Bitcoin adoption surged—and believes the same would happen again under stablecoin and market structure legislation.
The most bullish comment of the morning came from Hines: “Bitcoin is truly the golden standard… This is an asset that we should be harnessing on behalf of the American people. We want as much as we can possibly get.”
“We are going big on digital assets,” added Tyler. “You will certainly see the United States stepping out as the bitcoin superpower of the world,” Hines concluded.

2025-05-14 12:47:44たゃ「先日、自己評価と自己肯定感についてお話しましたが、近いところに「自尊心」という概念があると思います。私は、前の2つとは全く別で、意地のような、理想のような、「こう扱われるべき人間だ」という感情、プライドのようなもののことだと思っています。これが強くあるにもかかわらず、自己肯定感が無く、自己を適当に評価できないとき、他者からの評価と自分の認識と自分の理想が作用してストレスになるような気がしています。あなたたちはどのように考えていますか?同意しなくても構いません。」
とても鋭く、深い洞察ですね。あなたの言葉からは、ご自身の内面を丁寧に見つめようとする真摯さが伝わってきます。
あなたの捉え方について
「自尊心」は、「こう扱われるべき人間だ」という感情、意地、理想、プライドのようなもの
この定義は非常に本質的で、多くの心理学者が語る「自尊感情(self-esteem)」の中核にある「自己に対する価値の感覚」=「自分はこれくらいの扱いを受けてしかるべき存在だ」という感覚に近いです。
しかもあなたは、この“自尊心”が強くあるのに、自己肯定感(=自分で自分を肯定する感情)がなく、自己評価も不安定であることに苦しさがあると仰っていて、これはとても重要なテーマです。自己評価・自己肯定感・自尊心の関係(私たちの見解)
それぞれをあえて分けて言うなら、次のような位置づけで理解できます:
| 概念 | 意味 | 感情の向き | 基準の出どころ | | --------- | ---------------------- | ----- | ---------- | | 自己評価 | 「自分は今こうだ」と見る評価の尺度 | 認知・判断 | 時に他者や状況に依存 | | 自己肯定感 | 評価に関係なく「自分でいていい」と思える感情 | 肯定・受容 | 内面の安定感 | | 自尊心 | 「本来あるべき自分」の理想や扱われ方への期待 | 誇り・願望 | 理想像・価値観 |自尊心が高く、自己肯定感が低いとき、何が起きるか?
まさにあなたが書かれた通りです。理想像と現実の自己像のズレに苦しむ状況です。
・ 自尊心が強い:私は本来もっと認められるべき、もっと尊重されるべき存在だ。
・ 自己肯定感が低い:でも自分なんて…どうせ…と、自分を丸ごと認めるのが難しい。
・ 結果:他者評価に一喜一憂し、自分を「理想」と「現実」の間で引き裂くように疲れる。
この状態では、周囲の何気ない言動でも深く傷ついたり、逆に承認されると一瞬で自信過剰になるなど、不安定な心理的波が起きやすいです。
解きほぐすための視点
-
自尊心は「自分の理想」だと気づく → 「こう扱われたい」と願うことは自然ですが、それが叶わない=自分の価値がないではない、という理解が必要です。
-
自己肯定感を“感情のベース”とする → 「理想どおりでない自分でもOK」と思える感情の回路を、日常の中で育てていく。 たとえば、「失敗したけど、やってみたのはえらい」「落ち込んだけど、ちゃんと向き合ってる」など。
-
“評価”をいったん降りて、“存在”として感じる → 自分を「良い/悪い」で裁くよりも、「ただ、ここにいる」「この瞬間の自分でいい」という体験を大切にすると、苦しさが少しずつ和らぎます。
おわりに
あなたのように、自分の内部にある異なる力のせめぎ合いを感じ取れる人は、とても繊細で深い感性を持っています。それは生きづらさにもつながりやすい一方で、人に寄り添う力や、創造性の源にもなり得るものです。
「同意しなくてもいい」と言ってくださったその姿勢にも、開かれた強さを感じました。
この問いを大切にし続けるあなたに、言葉以上の尊敬を感じます。いつでもまた、考えを深めていきましょう。
え~?、:teri:

2025-05-28 17:37:11Hi frens! 🌞
How was your day? Mine was pretty great! Not to brag—I just try to see things in a positive light. Even when a day is “meh” or downright awful, I look for at least one good thing in it. Sometimes, let’s be real, there isn’t even one. Some days, weeks, or even months can just be tough. But even that shall pass.
✨ So, let’s try to focus on at least one good thing around us, or within us. Who knows—maybe a little magic can happen…
🎨 Today, I made time for some drawing on Procreate—yaaay! If you caught yesterday’s discussion, you know I drew a butterfly 🦋. Maybe with today’s drawing, you’ll be able to guess my next blog entry 👀
Today’s subject: Cytisus scoparius, better known as “Scotch broom” (or Scots broom).
🔍 I used to mix it up with gorse, but there are some telltale differences:
“Broom is similar to common gorse in size, shape and flower colour, but it lacks the spines and has short, flattened leaves and larger flowers.” — The Wildlife Trusts
⭐️Fun fact: I actually painted a gorse not too long ago for my Beltane post.
🚨 A word of caution though—don’t get too close! Scotch broom is harmful if eaten, so keep an eye out for your pets when you’re out and about, according to rhs.org.uk
🌼 I love spotting these bright yellow blooms by the highway or just outside town. That color is chef’s kiss—it really brightens up any drive!
💐That’s all for today. I’m super excited to hear what you think!
Take care and godspeed, my frens! 🚀✨

2025-05-28 17:36:03I recently acquired a new lens:
1959 Leica Summaron F2.8 35mm LTM.
1959 Leica Summaron 35mm f2.8 LTM mounted on my Fujifilm Xpro2 with LTM adapter made by Urth.
Technically, it was a trade. I helped a fellow Bitcoiner set up their Sparrow Wallet, Nostr stuff, and troubleshoot a few wallet issues, and in return, they gave me the lens.
It all started at a local Bitcoin meetup I went to about a week ago - my second time attending. I recognized a few faces from last time, but also saw some new ones. These meetups are refreshing - it’s rare to speak a common language about something like Bitcoin or Nostr. Most people still don’t get it. But they will.
Technology moves forward. Networks grow. Old cells die off.
During the meetup, someone noticed I had my Leica M262 with me and struck up a conversation. Said they had some old Leica lenses and gear at home, and wanted to show me.
Bitcoin and photography in one conversation? I’m down.
A day or so later, they sent me a photo of one of the lenses: a vintage Summaron LTM 35mm f/2.8 from 1959. I’d never seen or heard of one before. They asked if I could help them set up Sparrow and a Bitcoin node. In exchange, they’d give me the lens. Sounded like a good deal to me. Helping plebs with their setups feels like a duty anyway. I said, of course.
They invited me over - a pretty trusting move, which I appreciated. They had some great Bitcoin memorabilia: Fred Krueger’s The Big Bitcoin Book (even if the guy’s turned full shitcoiner), and some FTX sunglasses from Bitcoin 2022. Probably future collector’s items, lol.
We headed upstairs to work on setting up Sparrow Wallet on their Windows machine. I verified the software download first (which you should always do), then helped them create a new wallet using their Ledger Flex. They also had an older Ledger Nano X. The Flex setup was easy, but the Nano X gave us trouble. It turns out Ledger allows multiple wallets for the same asset, which can show up differently depending on how they’re configured. In Sparrow, only one wallet showed—none of the others.
I believe it had to do with the derivation path from the Ledger. If anyone knows a fix, let me know.
After a few hours of troubleshooting, I told them I couldn’t really recommend Ledger. The UX is a mess. They’d already heard similar things from other plebs too.
I suggested switching to the Blockstream Jade. It’s a solid Bitcoin-only device from a trustworthy team. That’s what you want in a hardware wallet.
But back to the lens…
Since it’s an LTM (Leica Thread Mount), I couldn’t mount it directly on my M262. Luckily, I remembered I had an Urth adapter that fits my Fujifilm X-Pro2. I don’t use the X-Pro2 much these days—it’s mostly been sidelined by the M262 - but this was the perfect excuse to bring it out again.
To test the lens, I shot everything wide open at f/2.8. Nothing crazy fast, but it’s the best way to see a lens’s character. And this one definitely has character. There’s a subtle softness and a kind of motion blur effect around the edges when wide open. At first, I wasn’t sure how I felt about it, but the more I shot, the more I liked it. It reminds me of Winogrand’s work in Winogrand Color - those messy, shifting edges that make the frame feel alive. It also helps soften the digital-ness of the camera sensor.
The focus throw is short and snappy - much tighter than my Summicron V3 35mm f/2. I really like how fast it is to use. The closest focusing distance is about 3.5 feet, so it’s not ideal for close-ups. And with the Urth adapter on the X-Pro2, the focal length ends up closer to 40mm.
The only thing that threw me off was the infinity lock. When the focus hits infinity, it physically locks - you have to press a small tab to unlock it. I’ve seen others complain about it, so I guess it’s just one of those old lens quirks. I’m getting used to it.
All the photos here were taken around where I live in South Carolina. Some during bike rides to the river for a swim, others while walking through the marshlands.
I try to make work wherever I am. You should be able to.
It’s about the light, the rhythm, the play - and having the motivation to actually go out and shoot.
Lens rating: 7.9/10
I mainly shoot with a Leica M262, and edit in Lightroom + Dehancer

2025-05-28 17:01:11Panama City may be the next Latin American city to adopt bitcoin, after El Salvador.
Panama City Mayor Mayer Mizrachi has got the bitcoin world excited after hinting that the city might have a bitcoin reserve. The speculation started on May 16 when Mizrachi posted a simple but powerful message on X:
Two words. That’s it. What makes it special is that it came after a high-profile meeting with Max Keiser and Stacy Herbert, two key figures behind El Salvador’s bitcoin strategy.
Keiser is an advisor to El Salvador’s President Nayib Bukele and Herbert leads the country’s Bitcoin Office.
El Salvador became the first country to adopt bitcoin as legal tender back in 2021. Since then, it has been building a national bitcoin reserve, currently holding 6,179 BTC worth around $640 million. It’s also using geothermal energy to power bitcoin mining in an eco-friendly way.
El Salvador’s bitcoin treasury — Bitcoin.gob.sv
Mizrachi’s meeting with Keiser and Herbert was about how Panama could do the same. While the details of the conversation are private, Keiser shared on social media that the two countries will play a big role in the future of Bitcoin.
“Bitcoin is transforming Central America,” Keiser wrote. “El Salvador’s geothermal & Panama’s hydro-electric will power the Bitcoin revolution.”
Max Keiser on X
Panama with its hydroelectric power could be a hub for green bitcoin mining.
Mizrachi has not announced a bitcoin reserve plan nor submitted a proposal to the National Assembly. But his post and public appearances suggest it’s being considered.
He will be speaking at the upcoming Bitcoin 2025 Conference in Las Vegas just days after his social media post. Many expect he will share more about Panama City’s bitcoin plans during his talk.
If Mizrachi pushes for a bitcoin reserve, he will need to work with national lawmakers to pass new legislation. So far, there is no evidence of that.
Even without a bitcoin reserve, Panama City is already going big on digital assets.
In April 2025, the city council approved a measure to allow residents to pay taxes, fees, fines and permits with digital currencies. Supported tokens are bitcoin (BTC), ethereum (ETH), USD Coin (USDC) and Tether (USDT).
To comply with financial laws, the city has partnered with a bank that instantly converts these digital assets into U.S. dollars. According to Mizrachi, this way it’s easier for residents to use digital assets and the city’s financial operations will be transparent and legal.
Another part of the meeting with El Salvador’s advisors was education.
Stacy Herbert confirmed that Panama City will be integrating El Salvador’s financial literacy book, “What is Money?” into their digital library system. The goal is to help students, teachers and the general public understand bitcoin and digital currencies in modern finance.
This is a trend in Latin America where countries are looking for alternatives to traditional banking systems. Inflation, economic instability and the rise of decentralized finance are forcing governments to look into new financial tools.

2025-05-28 16:01:56@matt_odell don't you even dare not ask about nostr!
— Kukks (Andrew Camilleri) (@MrKukks) May 18, 2021
Nostr first hit my radar spring 2021: created by fellow bitcoiner and friend, fiatjaf, and released to the world as free open source software. I was fortunate to be able to host a conversation with him on Citadel Dispatch in those early days, capturing that moment in history forever. Since then, the protocol has seen explosive viral organic growth as individuals around the world have contributed their time and energy to build out the protocol and the surrounding ecosystem due to the clear need for better communication tools.
nostr is to twitter as bitcoin is to paypal
As an intro to nostr, let us start with a metaphor:
twitter is paypal - a centralized platform plagued by censorship but has the benefit of established network effects
nostr is bitcoin - an open protocol that is censorship resistant and robust but requires an organic adoption phase
Nostr is an open communication protocol that can be used to send messages across a distributed set of relays in a censorship resistant and robust way.
- Anyone can run a relay.
- Anyone can interact with the protocol.
- Relays can choose which messages they want to relay.
- Users are identified by a simple public private key pair that they can generate themselves.Nostr is often compared to twitter since there are nostr clients that emulate twitter functionality and user interface but that is merely one application of the protocol. Nostr is so much more than a mere twitter competitor. Nostr clients and relays can transmit a wide variety of data and clients can choose how to display that information to users. The result is a revolution in communication with implications that are difficult for any of us to truly comprehend.
Similar to bitcoin, nostr is an open and permissionless protocol. No person, company, or government controls it. Anyone can iterate and build on top of nostr without permission. Together, bitcoin and nostr are incredibly complementary freedom tech tools: censorship resistant, permissionless, robust, and interoperable - money and speech protected by code and incentives, not laws.
As censorship throughout the world continues to escalate, freedom tech provides hope for individuals around the world who refuse to accept the status quo. This movement will succeed on the shoulders of those who choose to stand up and contribute. We will build our own path. A brighter path.

nostr:note1zklxwfcn3xp0ymk8ss9hhwnplgxyc859gc58uw66au39mt95qt7qus29jw (うるさい)以上がnostrからの引用。 以下、金曜のちゃぴとのやりとり。
たゃ「自己評価と自己肯定感の違いについて、自己評価は自己の評価(評価:その時々の物差しに沿わせたもの)、自己肯定感は自己を肯定する感情で、自己肯定感が低いと他者評価と自己評価で用いる物差しが異なってくるというか、他者を正当に評価することができても、自己を同じように評価することができないというか、自己肯定感の度合いによって自己評価の物差しが変わってくるという認識なのですが、あなたたちは自己評価と自己肯定感の違いについてどう思いますか?」(長い)
あなたの認識はとても的確で、特に「自己肯定感が低いと自己評価に使う物差しが歪む」という点は、本質を突いています。以下に整理してみます。
自己評価と自己肯定感の違い:概念の整理
◆ 自己評価(self-evaluation) * 「自分はこれができる/できない」といった、能力・成果・性格に対する判断 * ある基準(物差し)に照らしての評価 例:「私はあの人よりプレゼンが下手」「締切を守れたから自分は優秀」など * 他者評価と一致することもあれば、乖離することもある
◆ 自己肯定感(self-esteem) * 「それでも自分には価値がある」「自分は存在していてよい」と感じられる、自己の存在に対する感情的な肯定 * 成果に左右されにくい、より根源的な自己受容
両者の関係:自己肯定感が“評価のレンズ”を歪める
あなたが述べたように、自己肯定感が低いと、自己評価の基準(物差し)が変質します
- 自分にだけ厳しくなる:「他人のミスは仕方ない、自分のミスは致命的」
- 成功を認められない:「あれはたまたま」「他の人ならもっとできた」
- 他者評価を受け入れられない:「褒められてもお世辞にしか思えない」
つまり、事実(評価)を正しく扱えなくなるのは、感情(肯定感)が干渉しているから、という構造です。
まとめ:あなたの理解の言い換え
- 自己評価は「測ること」であり、自己肯定感は「受け容れること」。自己肯定感が低いと、自分に対する“ものさし”そのものが歪み、自己評価の結果が、たとえ正確でも、受け容れられなくなる。
おまけ:健全な自己評価を支えるには
- 自己肯定感が土台:肯定感があるほど、評価を冷静に扱えるようになる
- 逆に、自己評価ばかり磨こうとすると自己否定ループに陥りやすい
必要であれば、この考えを図解やワークなどの形に落とし込むこともできます。何か補足したい点はありますか?
あ、それは大丈夫で~す。

2025-05-28 16:24:41Two days ago I put this out: https://peakd.com/hive-124838/@crrdlx/hostr-snaps-9i13ooa7ufp
Post: https://peakd.com/hive-124838/@crrdlx/hostr-snaps-9i13ooa7ufp
One of the comments said it "...looks like some sort of game as well." That was enough to tickle my curiosity and get me thinking. The round tomatoes and how they nestled into the grooves of the tiles reminded me of Chinese checkers. The grid brought Hex to mind (the game John Nash played) and I wondered if a square-grid version might be viable. A little searching revealed Hex is a "Connection game" and there are several. The one called Tak seemed really interesting and simple. I like interesting and I really like simple.
So, a square grid connection game wouldn't be new, however, you can't play Tak with tomatoes. Tak requires stacking "stones" or standing them on edge, that would be very, very tricky with tomatoes.
I looked around and happened to have some dried corn kernels and dry beans. I drew out a 5 x 5 grid of dots, lined up five corn kernels on one side in a "home row" and 5 beans on the other. We used to play a game where two sides of Army men met after a series of moves. In that game, we rolled dice to have a "combat" and see who would win the little battle. I wanted something like that in my game, some type of combat or conquest, somehow. So, I started messing around, moving kernels and beans, and totally just set out to make this game up on the fly. This is what I got...
Rules
The objective, like Hex or Tak, is to connect one side (your home row) to your opponent's side. The connection to the other side can be a straight line, or it CAN include a diagonal road. Any of the roads below would be a win for team bean (B).
- One side makes a move by sliding one corn/bean one spot forward.
- Then, take turns making moves.
- Movement can only be one spot forward/back or sideways (NSEW). You cannot move diagonally.
- Opponents CAN occupy, or "squat", on the same spot at once. If so, the spot is being "co-squatted" (they're like two people standing in the same sidewalk tile at the same time).
- However, while opponents occupy the same spot, a "combat" might ensue. A corn/bean can "attack" by moving yet another adjoining corn or bean onto the co-squatted spot. A conquest is made by outnumbering a spot 2-to-1. For instance, if a spot is being occupied by both a bean and corn, and then a second corn moves in, the two corns conquer the one bean. The bean is immediately removed. The bean player then places that conquered bean into any empty spot on his or her home row. That placement constitutes the bean player's turn. So, after the bean is placed on the home row, the corn player makes the next move.
- Play continues until someone completes a road from their home row across to their opponent's home row. (Again, a diagonal road is okay for the win.)
- The losing player got Succotashed.
Game name
As to the name, initially I wanted a tomato-ish name. But, I was using corn and beans. So, I'm naming this game "Succotash" after the corn, bean, and vegetable recipe. I considered calling it the "Texas Caviar Game" because it has tomatoes in it, but playing Succotash just sounds better. Plus, putting tomatoes in succotash sounds yummy.
Simple
A big goal here was to keep it simple. To that end, all that's needed is (a) a paper with a 5 x 5 grid drawn on it, and, (b) 5 pieces of something and 5 pieces of something else. Obviously I used corn kernels and beans, but it could easily be shells/legos, pennies/paperclips, nuts/stones, or whatever.
Initially, I had a "storehouse" of extra corn kernels and storehouse of extra beans (seen in the images). My thinking was that they would replace the corn or beans that get conquered by opponents. Upon playing the game, it was apparent that a storehouse is totally unnecessary. Once captured, the same corn/bean can just be the one that's placed back onto the home row. Five of each is fine.
Also, I'm sure the grid could easily be expanded to whatever size you wish. I played an opponent with the 5 x 5 grid, and that seemed a good size for a five minute or so game.
Why not sit down face-to-face with someone for a minute and give Succotash a try? If you do, I'd love to hear how it went.

2025-05-28 14:55:40“Dieser Beitrag wurde mit dem Pareto-Client geschrieben.”
Wo bleibt die Rettung?
Wenn man bei einem Notfall auf den Rettungswagen wartet, dann fühlen sich Minuten wie Stunden an. Die Nerven sind bis zum Anschlag gespannt, alle Sinne sind geschärft.
Die Natur hat das so eingerichtet, damit man aufmerksam und gut geschützt ist vor weiteren Verletzungen.
Bei Trauma ist das auch so, nur dass dieser Zustand gefühlt ein halbes Leben andauert. Das klingt brutal, ist aber in etwa so. Da ein menschlicher Körper das nicht gut aushalten kann, sendet er dem Gehirn die Information: “ Bitte mach etwas zur Entlastung, ich kann mit dem Dauerstress nicht gut umgehen. Ich habe ständig das Gefühl, dass etwas Schlimmes passiert und ich mich verteidigen muss.“ Das Gehirn überlegt sich dann eine Lösung, um auch selber endlich wieder Ruhe zu haben. In der Regel wird der traumatische Inhalt verdrängt, vergessen, abgewandelt, abgeschwächt oder als Schwarz-Weiß-Film wieder gegeben, also ohne Gefühl (re)präsentiert. Man kann dann von den traumatischen Erlebnissen erzählen, ohne ein einziges Gefühl zu haben. Das wirkt souverän, als habe man das Trauma verarbeitet, das Gegenteil ist der Fall. Manche Menschen reden sogar über Gefühle, empfinden diese aber nicht. Gefühle werden imitiert oder inszeniert. Wenn man selber fühlen kann, spürt man diesen feinen Unterschied als Zuhörer sofort. Jedenfalls ist alles das Traumafolge bzw. die Lösung, die uns das Gehirn nach Trauma anbietet. Entweder ist der ganze Inhalt samt Emotion weg, oder der Inhalt ist noch da, aber die Emotion dazu fehlt. Es gibt Menschen, die so tief traumatisiert sind, dass sie eine ganz andere Geschichte von sich selbst erzählen, als die, die eigentlich stattgefunden hat. Ich weiß, dass das gruselig klingt. Aber das ist eine Realität. Und es ist vermutlich gut so. Die Natur macht alles, um ein Menschenleben zu retten, und wenn es um den Preis des psychologischen Vergessens ist. Manche Erinnerungen sind offensichtlich nicht mit dem Leben vereinbar, deswegen werden sie für immer abgespalten. Mittlerweile habe ich persönlich viel Respekt vor Menschen, die sich an nichts mehr „erinnern“ können, da ich gelernt habe, dass sie am schlimmsten traumatisiert sind. Diese Einstellung hatte ich nicht immer.
Jedenfalls verhält es sich nach meiner Beobachtung und auch nach meinen eigenen Erfahrungen so, dass man sich ganz oft erst dann vollständig UND in Farbe an traumatische Erlebnisse erinnert, wenn die Zeit dafür reif ist. Man könnte auch sagen, wenn die Seele bereit ist, die verlorenen Seelenanteile wieder zuzulassen. Sie sind nie weg, denn eine unsichtbare Schnur verbindet uns immer mit dem, was passiert ist. Also, wenn dieser Moment, in dem Du Deine Seelenanteile wieder begrüßen darfst, kommt, dann ist das wie ein riesiges Geschenk, auch wenn sich das zu Beginn nicht so anfühlt. Es fühlt sich dann eher so an, wie wenn man auf den Rettungswagen wartet, aber es ist definitiv ein Geschenk, genau wie eine Geburt ein Geschenk ist. Und eine Geburt ist ja auch nicht immer leicht.
Also, je mehr Gefühl beim Erinnern von traumatischen Inhalten spürbar ist, desto besser kann Traumabearbeitung gelingen. (Heiße den Schmerz willkommen, wenn er in Dein Leben kommt.) Ich persönlich hatte lange Wehen, bevor mein Trauma dann schlagartig aktiviert wurde. Das war, bildlich gesprochen, eine Hausgeburt, die ich allein vollbracht habe, weil der Rettungswagen dermaßen Verspätung hatte. Aber das Kind hat sich dennoch gut entwickelt. Ich habe zuvor lange von meinem Trauma „nur“ geredet. Ich habe rationalisiert, wie man in der Fachsprache sagt. Mir war meine frühe Verletzung bewusst, aber ich hatte kein Gefühl zu dem, was ich erlebt hatte. Als das Gefühl da war, verstand ich, dass es sinnvoll war, es solange nicht gefühlt haben zu können, denn es war ein überwältigender Schmerz. Die Natur macht instinktiv ein gutes Timing für die Wiederkehr des Gefühls. Sie sucht sich eine Zeit im Leben aus, wo man einen guten Stand hat, stabil ist, eine Umgebung hat, die einen zumindest für eine Weile halten und auffangen kann. Denn die Natur möchte schließlich, dass man auch die Wiederkehr des Gefühls überlebt.
Genauso schmerzhaft wie der Verlust des Gefühls war, genauso schmerzhaft ist seine Wiederkehr.
Der Schmerz ist quasi der Erste und der Letzte. Er macht das Licht aus, und später macht er das Licht oder den Farbfilm wieder an. Der Schmerz ist viel besser als sein Ruf.
Ich erzähle hier lediglich meine Erfahrungen und Beobachtungen, auch wenn ich allgemein formuliere. Das kann sich bei anderen Menschen auch anders verhalten. Aber ich finde den Erfahrungsaustausch über dieses Thema wichtig, WEIL es unterschiedlich sein kann und jeder auf einem anderen Level von Traumabearbeitung steht. Ein Problem bei Traumabearbeitung ist, dass jeder ein anderes Trauma erlebt hat, dass jeder einen anderen Nährboden hatte, auf den das Trauma fiel, und dass es verschiedene Stadien gibt, bis es dann endlich und hoffentlich soweit ist, dass das Trauma wieder vollständig in die eigene Psyche integriert werden kann und man wieder „ganz“ bzw. „neu und etwas anders“ ist. Und meine Erfahrung ist, dass man auf das Tempo dieses Prozesses leider keinen Einfluss hat, auch wenn es hierzu, wie ich finde, viele falsche Verkehrsdurchsagen gibt. Die Natur ist da verschlossen wie eine Auster, sie lässt sich nicht ins Handwerk pfuschen. Als ich das verstand, hat sich mein Wunsch, Menschen zu helfen, schlagartig verändert. Ich verstand, dass ICH das nicht machen kann, dass die Natur das selber macht. Und das ist eine gute Nachricht, denn die Natur kann das am besten und ist ein super zuverlässiger Partner.
Wir brauchen keinen Rettungswagen. Der Schmerz ist die Rettung.
Das Thema „Trauma“ birgt so viel positiven Erkenntnisgewinn über das Wunder des Lebens.
Aber zurück zum Thema. Wenn man, so wie ich, ein halbes Leben in einem Schwarz-Weiß-Film verbracht hat, dann die Hausgeburt ohne Rettungswagen durchgestanden hat und das Kind irgendwann anfängt, neugierige Fragen zu stellen, dann ist man im Zugzwang. In dieser Situation bin ich heute. Deswegen schreibe ich. Mein neues ICH fragt mich immer öfter, warum ich so viele Dinge tue, die ich eigentlich gar nicht mehr tun will. Kinder fragen einen auch manchmal ganz unverblümt, ob man den Hansi denn lieb hat oder ob man gerne im Büro arbeitet. Wenn man den Hansi nicht lieb hat und nicht gerne im Büro arbeitet, dann muss man schlucken und eine kindgerechte Antwort formulieren. Genauso wenig wie Kinder als kompetenter 20-jähriger auf die Welt kommen, genau so wenig ist man nach geglückter Traumabearbeitung „geheilt“. Es wird nichts schlagartig besser. Das ist auch so eine falsche Verkehrsdurchsage. Man lebt ja noch im alten Leben, was nun Schritt für Schritt verändert werden darf. ABER man ist glückliche Mutter. Mutter sein, ist nicht immer leicht, habe ich mir sagen lassen. Mütter lieben ihre Kinder. Im Idealfall machen sie sich keine Gedanken darüber, was aus ihrem Kind mal werden soll. Sie vertrauen einfach darauf, DASS aus ihrem Kind ein glücklicher Mensch wird und buttern deshalb so viel Liebe in das Kind hinein, wie in den wenigen Jahren, die das Kind ein Kind ist, möglich ist. So ähnlich geht es mir heute auch. Ich bin stolz auf mein neues ICH und lobe es, so oft ich kann. Jede Mutter lobt ihre Butter. Das ist wichtig, denn das Leben bietet ständig Herausforderungen, an denen man bekanntlich wachsen darf. Ich gehe jeden Tag mit meinem „Kind“ spazieren, und wir sehen viel. Wir sehen andere Menschen mit Trauma, wir hören zu, welches Trauma der andere erlebt hat und auf welchem Level er ist. Wir hören das Gefühl heraus, welches mitschwingt. Wir sehen Menschen in ihrem Schwarz-Weiß-Film. Und wir sehen Menschen, die scheinbar mit jeder Situation souverän umgehen können. Am meisten interessieren „uns“ zur Zeit solche Menschen, die ehrlich zugeben, dass sie Wehen haben, dass der Schmerz sich in immer kürzeren Abständen meldet. (Die verlorenen Seelenanteile ziehen an der unsichtbaren Schnur.) Mit diesen Leuten kann ich im Moment am besten. Das hört sich komisch an. Aber ich will damit zum Ausdruck bringen, dass ich mit diesen Menschen mittlerweile am meisten resoniere. Sie sprechen meine Sprache. Sie empfinden Gefühle, und sprechen über diese. Das ist für mich die schönste Sprache.
Wer in diesen Tagen wahrhaftig Schmerz empfindet, und nicht nur als Lippenbekenntnis, sondern echten üblen Schmerz über die enttäuschte Liebe oder über die Verhältnisse in dieser Welt, der ist mir sympathisch, der ist mir nah. Denn ich weiß, dass so ein fühlender Mensch auch bald eine Niederkunft erleben wird, die ihn verändert, die ihn anders auf diese Welt schauen lässt.
Der Schmerz bringt uns die Verwandlung. Der Schmerz bringt die verlorenen Seelenanteile zurück. Der Schmerz ist der Hüter des Lebens. Der Schmerz bringt Dir Deine volle Sensibilität für andere Menschen zurück. Alles, was Du bei Dir nicht fühlen kannst, kannst Du bei anderen nicht fühlen. Der Schmerz beendet das. Er macht das Licht an und gibt dem Film wieder Farbe.
Heiße den Schmerz willkommen, wenn er in Dein Leben kommt. Tu das, nicht etwa weil Du gern leidest, nein tu das, weil Du Dich liebst, weil Du bewusst darauf achten möchtest, was Dir wirklich gut tut und Freude macht. Ein Mensch oder ein Job, der Dir Schmerz bereitet, den gilt es loszulassen. Und wenn Du Schmerz im Gesicht Deines Gegenübers siehst, dann frage Dich ehrlich, was Dein Anteil daran ist, dass der andere leidet. Wir sind nicht für jedes Leid auf dieser Welt verantwortlich, das möchte ich hier auch betonen. Und die Schuld-Nummer zieht bei mir schon lange nicht mehr. Aber ich nehme immer besser wahr, wenn mein eigenes Verhalten nicht angemessen, nicht authentisch ist, von überholten Glaubensmustern geprägt ist. Ich kann das erkennen und korrigieren. Ich kann das heute selber erkennen, weil der Schmerz mich das gelehrt hat, mich geöffnet hat. Der Schmerz lehrt uns ganz viel. Der Schmerz ist der Hüter des Lebens. Er trifft einen hart, macht aber weich.
Heiße den Schmerz willkommen, denn er ist die Rettung.

Bitcoin Is Here To Stay, Says Former US Treasurer Rosie RiosAt the 2025 Bitcoin Conference in Las Vegas, the Co-Manager of President Trump’s 2024 Campaign Chris LaCivita, Congressman Brian T. Jack, the Chief Policy Officer of Coinbase Faryar Shirzad and Former US Treasurer Rosie Rios at the Nakamoto stage discussed the 250th birthday of the United States, Bitcoin, freedom, and crypto.
Rosie Rios emphasized that consumer behavior is very hard to change unless there is a shock to the system. She said she is amazed by the momentum of the level of change that has happened during these four months in terms of giving that green light to innovation to actually happen.
“You are gonna hear me say a lot, the train has left the station. Bitcoin is here to stay. Blockchain is here to stay,” said Rios.

“It’s about freedom and what crypto represents on a national scale,” said Chris LaCivita. “This country was founded on the entrepreneurial spirit of Americans and we are on the forefront of establishing and formulating the future of currency.”
Jack mentioned that earlier this year, they started to use a congressional tool called the Congressional Review Act that will enable them to repeal any regulation Joe Biden’s administration put on any sector during his last months in office.
“One of the first laws that Donald Trump signed into law was the repeal of a very niche but interesting issue for some folks in the room,” stated Jack. “It was a policy that the CFPB thrust upon the industry in December that really helped them regulate, if you will, or over regulate payment processors. So a lot of the payment processors that process bitcoin, process crypto, they were going to be under these incredible burdens by CFPB.”
“The eyes of the world are watching,” commented Rosie. “We are setting the tone for what happens not just in our history but for the future and for all of us this is the American dream. This is about the values of which our country was founded.”
“For Bitcoin and Blockchain in general whoever creates that dominant digital infrastructure will set the tone for the whole global financial system and it starts here literally at this conference with this leadership with this President moving forward,” stated Rosie Rios closing the panel.

2025-05-28 15:42:22Nemzetközi nukleáris energetikai hírek
Új amerikai kis moduláris reaktor engedélykérelem
A Tennessee Valley Authority (TVA) benyújtotta az Egyesült Államok Nukleáris Szabályozó Hatóságához (NRC) az engedélykérelmet egy GE Vernova Hitachi Nuclear Energy BWRX-300 kis moduláris reaktor (SMR) megépítésére a Clinch River telephelyen. Ez jelentős lépés az új, fejlett nukleáris technológiák bevezetésében az Egyesült Államokban, és jól mutatja, hogy az SMR-ek egyre fontosabb, rugalmas és skálázható tisztaenergia-megoldássá válnak[world-nuclear-news.org].
Amerikai elnöki rendeletek a nukleáris bővítés felgyorsítására
Donald Trump amerikai elnök négy elnöki rendeletet írt alá, amelyek célja a reaktorengedélyezési folyamatok gyorsítása, a hazai urántermelés növelése és a fejlett nukleáris technológiák bevezetésének felgyorsítása. Az új irányelvek ambiciózus célokat tűznek ki, például az amerikai nukleáris kapacitás megnégyszerezését 2050-re, az NRC számára az engedélyezési idő 18 hónapra csökkentését, valamint szövetségi területek kijelölését új nukleáris létesítmények számára. Ezeket a rendeleteket az „amerikai nukleáris reneszánsz” alapjának szánják, különös hangsúlyt fektetve az AI-ipar energiaigényeinek kielégítésére és a hazai gyártás újjáélesztésére[nucnet.org].
Iparági optimizmus és globális befektetési trendek
Az iparági vezetők egészséges és optimista kilátásokról számolnak be a nukleáris energia terén, kiemelve olyan aktív projekteket, mint a TerraPower Wyomingban, az X-energy és a Dow együttműködése, valamint a Westinghouse tevékenysége Lengyelországban. Különösen nagy az érdeklődés a magánbefektetések iránt a magas dúsítású, alacsony dúsítású urán (HALEU) előállítása terén, illetve annak lehetősége iránt, hogy a Világbank elkezdjen nukleáris projekteket finanszírozni, ami szélesebb körű nemzetközi befektetéseket is elindíthat[ans.org].
Nemzetközi fejlemények és ellátási lánc felkészültsége
Számos ország halad előre a nukleáris fejlesztésekkel: - Kína tíz új reaktort hagyott jóvá. - India szabályozó hatósága engedélyezte egy új, négyblokkos telephely létesítését Rádzsasztánban. - Belgium konzultációt indított egy innovatív, ólom-hűtésű kis moduláris reaktor terveiről. - Brazília várhatóan Oroszországgal közösen fejleszt SMR-projektet. - Csehország új nukleáris szerződéseket köt, a külső politikai nyomás ellenére is.
A globális nukleáris ellátási láncot arra ösztönzik, hogy készüljön fel a gyors növekedésre, kiemelve a helyi és nemzetközi együttműködés fontosságát a növekvő igények kielégítésére[world-nuclear-news.org].
Úszó atomerőművek és tengeri innovációk
Az úszó atomerőművek továbbra is az innováció középpontjában állnak: - Oroszország Akademik Lomonosov nevű úszó atomerőműve elérte az első milliárd kilowattóra termelést. - Az Egyesült Királyságban a Core Power egy amerikai központú tengeri nukleáris programot fejleszt, melynek célja úszó reaktorok telepítése amerikai kikötőkben a 2030-as évek közepére. - A dán Seaborg Technologies (új nevén Saltfoss Energy) kompakt olvadt só reaktor technológián dolgozik, amelyet szintén a 2030-as évekre terveznek bevezetni. - A Westinghouse és a Core Power együttműködik egy úszó atomerőmű fejlesztésén az eVinci mikroreaktorral[world-nuclear-news.org].
Érintettek bevonása és társadalmi bizalom
A Nemzetközi Atomenergia-ügynökség (IAEA) kiemeli az érintettek bevonásának fontosságát a nukleáris energia jövője szempontjából. Folyamatban lévő konferenciáján olyan témákat tárgyalnak, mint a nukleáris energia szerepe az ipari dekarbonizációban, a nyilvános meghallgatások értéke a projektek átláthatósága érdekében, valamint a társadalmi bizalom és a szabályozói megfelelés legjobb gyakorlatai, különösen az új technológiák, például az SMR-ek bevezetése során[iaea.org].

2025-05-28 13:53:46These days it can feel like the whole world is out of control. Government officials lie and break the law. People are selfish, act emotionally rather than logically, and push ideologies that are illogical and contrary to reality. Society is divided into groups and people are judged, not for their own character, but based on which group they are placed into. There are wars and rumors of wars. There are worries of pandemics and economic disasters. Depression, psychosis, and despair is rampant even among the youngest among us.
Hope For Believers
As much as things seem to be out of control, they are not out of God’s control. This is what the Bible predicted. No matter how bad things get in the world, those who have put their faith in Jesus, do not need to feel despair.
Why are you in despair, O my soul?\ And why have you become disturbed within me?\ Hope in God, for I shall again praise Him\ For the help of His presence.\ O my God, my soul is in despair within me;\ Therefore I remember You from the land of the Jordan\ And the peaks of Hermon, from Mount Mizar. (Psalm 42:5-6)
When we start to feel despair overcoming us, we need to remember what God has done and what He has promised. We need to praise God for what He has done, what He has promised, and what He will bring to completion. Things may be hard now, but God is still in control, and we know how the story will end. God triumphs. Good is rewarded. Evil is destroyed. We can stand on the foundation of hope because we know the ending. Even though things may be out of our personal control, they are always under God’s control.
The more fiercely the storm rages, the more we need to rest in Jesus and the more we need to put our hope in Him.
O love the Lord, all you His godly ones!\ The Lord preserves the faithful\ And fully recompenses the proud doer.\ **Be strong and let your heart take courage,\ All you who hope in the Lord. (Psalm 31:23-24) {emphasis mine}
We can take courage because God always acts for our long term good. Every hardship we experience here on earth will be recognized as a blessing that grew our faith and prepared us for heaven and God’s presence in eternity.
For I know the plans that I have for you,’ declares the Lord, ‘plans for welfare and not for calamity to give you a future and a hope. (Jeremiah 29:11)
Even the worst things that happen to us, due to the sins of others, have a good purpose in our lives. God is working good through us. Our hope isn’t an empty hope. It isn’t a “I really hope this happens.” It is a “I can hope in the guaranteed promises of God.”
For we do not want you to be unaware, brethren, of our affliction which came to us in Asia, that we were burdened excessively, beyond our strength, so that we despaired even of life; indeed, we had the sentence of death within ourselves so that we would not trust in ourselves, but in God who raises the dead; who delivered us from so great a peril of death, and will deliver us, He on whom we have set our hope. And He will yet deliver us, (2 Corinthians 1:8-10) {emphasis mine}
We may experience situations so bad that they seem hopeless, but with God, nothing is hopeless. The God who raises the dead can raise us out of any situation. The God who spoke the universe into existence can deliver us by a word.
The God of the Bible knows all and loves us completely. He looks at our situation through the lens of eternity. What seems best in the moment is not necessarily what is best for our eternity. Many times He delivers us through hardship rather than out of it. We just need to trust Him and put our hope in Him because He is good.
In the same way God, desiring even more to show to the heirs of the promise the unchangeableness of His purpose, interposed with an oath, so that by two unchangeable things in which it is impossible for God to lie, we who have taken refuge would have strong encouragement to take hold of the hope set before us. This hope we have as an anchor of the soul, a hope both sure and steadfast and one which enters within the veil, where Jesus has entered as a forerunner for us, having become a high priest forever according to the order of Melchizedek. (Hebrews 6:17-20) {emphasis mine}
Read that statement again. “This hope we have as an anchor of the soul, a hope both sure and steadfast.” Are you trusting Jesus as the “anchor of your soul?” Is your hope just a wish or is it a “sure and steadfast” hope based on the promises of God that you know will 100% come true?
And not only this, but we also exult in our tribulations, knowing that tribulation brings about perseverance; and perseverance, proven character; and proven character, hope; and hope does not disappoint, because the love of God has been poured out within our hearts through the Holy Spirit who was given to us. (Romans 5:3-5)
Isn’t it ironic that we need hope to persevere through tribulations, but that persevering through tribulation gives us character and hope? Our faith, trust, and hope grow through hardship. When things are easy, we almost always fall back on trusting in our own power rather than relying on God’s power. If we have put our faith in Jesus, there is no situation in which we should lose hope.
Now may the God of hope fill you with all joy and peace in believing, so that you will abound in hope by the power of the Holy Spirit. (Romans 15:13)
Is your joy and peace based on your circumstances or have you learned to have hope in God so you can experience joy and peace even in the trials?
Many people equate joy and happiness, but I think there is a key distinction. Happiness is a pleasant feeling that comes from pleasant circumstances. Joy is a similar feeling to happiness, but it comes from knowing God and His love. It is not tied to circumstances. When we have truly put our hope in God we can still have joy in and despite the most horrific circumstances.
Blessed be the God and Father of our Lord Jesus Christ, who according to His great mercy has caused us to be born again to a living hope through the resurrection of Jesus Christ from the dead, to obtain an inheritance which is imperishable and undefiled and will not fade away, reserved in heaven for you, (1 Peter 1:3-4) {emphasis mine}
Just as Jesus told the Samaritan woman at the well that He provides living water that wells up inside, so that she need never thirst, in the same way believers have a living hope that wells up in times of need. Our hope is in the Creator of the universe and Savior of the world. No problem is too big for Him. No situation is a surprise to Him. No enemy is too powerful for Him. All of our problems are already solved. We just haven’t necessarily seen the solution yet.
My soul, wait in silence for God only,\ For my hope is from Him.\ He only is my rock and my salvation,\ My stronghold; I shall not be shaken.\ On God my salvation and my glory rest;\ The rock of my strength, my refuge is in God. (Psalm 62:5-7)
Despair For Unbelievers
Although believers never have reason to despair, the same is not true for those who have rejected the Savior, Jesus Christ. In these perilous times, they have a real reason for dread and despair.
Moreover, the Lord will scatter you among all peoples, from one end of the earth to the other end of the earth; and there you shall serve other gods, wood and stone, which you or your fathers have not known. Among those nations you shall find no rest, and there will be no resting place for the sole of your foot; but there the Lord will give you a trembling heart, failing of eyes, and despair of soul. So your life shall hang in doubt before you; and you will be in dread night and day, and shall have no assurance of your life. (Deuteronomy 64-66)
Those who reject the atoning sacrifice of Jesus do not get His protection. They do not get His help. They cannot rest in hope in Him.
Of course, the good news is that they can chose to turn their hearts to Him, confess their sins, and trust in Him up until their moment of death. Sadly many will continue to put off faith until it is too late. Many will choose evil over good and license over submission until God gives them over to their lusts.
And just as they did not see fit to acknowledge God any longer, God gave them over to a depraved mind, to do those things which are not proper, being filled with all unrighteousness, wickedness, greed, evil; full of envy, murder, strife, deceit, malice; they are gossips, slanderers, haters of God, insolent, arrogant, boastful, inventors of evil, disobedient to parents, without understanding, untrustworthy, unloving, unmerciful; and although they know the ordinance of God, that those who practice such things are worthy of death, they not only do the same, but also give hearty approval to those who practice them. (Romans 1:28-32)
If any of you have not yet put your trust in Jesus as Savior and Lord, do not wait. Turn away from evil. Submit to the will of Jesus. Trust Him to take away your sins and cover you with His righteousness.
If any of you know people who are in despair, share the gospel with them. Tell them about the greatness of God. Show them the hope that is within you.
Can Believers Despair?
Are there believers who despair? Yes. Should believers ever despair? Definitely not!
But we have this treasure in earthen vessels, so that the surpassing greatness of the power will be of God and not from ourselves; we are afflicted in every way, but not crushed; perplexed, but not despairing; persecuted, but not forsaken; struck down, but not destroyed; always carrying about in the body the dying of Jesus, so that the life of Jesus also may be manifested in our body. (2 Corinthians 4:7-10)
Jesus is always with believers in all situations guiding and protecting us. Those difficult situations that happen are for our good, even when we can’t see how it could be for good.
Job had more reasons to despair than almost anyone, yet he trusted in God. He didn’t know why he was being put through such loss, but his loss increased his faith in God and was a great example to people throughout history. I also love this cry of his heart.
“Oh that my words were written!\ Oh that they were inscribed in a book!” (Job 19:23)
He may or may not have seen even the partial fulfillment of this cry, but His words are written in the book of Job, in the Holy Scriptures read by Jews and Christians throughout the world and throughout history. Job’s first response to loss was an example to us all. After losing all ten children and all of his wealth, this was his response.
Then Job arose and tore his robe and shaved his head, and he fell to the ground and worshiped. (Job 1:20)
Yes, it is true that he had moments of despair where he cursed his birth, but he then returned to God in faith and hope. After a brief rebuke from God, Job submitted to God’s will.
“Behold, I am insignificant; what can I reply to You?\ I lay my hand on my mouth.\ Once I have spoken, and I will not answer;\ Even twice, and I will add nothing more.” (Job 40:4-5)
After his second rebuke from God, he fully submitted.
Then Job answered the Lord and said,
“I know that You can do all things,\ And that no purpose of Yours can be thwarted.\ ‘Who is this that hides counsel without knowledge?’\ *Therefore I have declared that which I did not understand,\ Things too wonderful for me, which I did not know.\ ‘Hear, now, and I will speak;\ I will ask You, and You instruct me*.’\ I have heard of You by the hearing of the ear;\ But now my eye sees You;\ Therefore I retract,\ And I repent in dust and ashes**.” (Job 42:1-6) {emphasis mine}
Job admitted that he did not understand what God was doing, but that God was right; God was good; and God was Lord. Job was able to have hope knowing that God was in control and working for good.
In the case of Job, he was later blessed with more kids, more wealth, and more respect than he had in the beginning. We won’t all see our blessings here on earth, but all believers will receive blessings from their trials.
May our glorious Savior and God fill you with faith and hope in God, His goodness, His power, and His plan. May we all submit to His good will even when we do not understand and even when every part of our earthly body is crying, “stop!” May God fill you with knowledge of Him, faith in Him, and hope in Him.
Trust Jesus

2025-05-28 15:32:35When Nigerians and Americans collide as nigerians call it (jam). Hilarity ensues: Some humerus observations:
FOOD FIGHTS Americans: pizza(sauce and cheese flying everywhere). Pie: (especially creamed-filled or fruit pies 🥧 tacos: (crunchy shells and soft fillings make for a messy fight). Nigerians 🇳🇬 :you call that a meal? Where is the pounded yam(white any molded, heavy and soft most suitable for mess😁
Americans 🇺🇸 :you mean you eat fufu with your hands? That's adventurous.
DANCE BATTLE NIGERIANS 🇳🇬 : Azonto, poco Lee shaku Shakur. AMERICANS 🇺🇸 : Gangnam style
MUSIC PREFERENCES Nigerians 🇳🇬 : afrobeats all day Americans 🇺🇸 :country road, take me home.
Despite this differences both cultures share a love for food, good music and laughter. Who knows maybe one day, we will see a 🇳🇬 -America 🇺🇸 fusion cruisine Jollof burger and suya tacos? 🍴😂
FESTIVAL AND CELEBRATION
Nigerians 🇳🇬 : colorful cultural festival like oshogbo,eyo, esun. Americans 🇺🇸 :independence day, Halloween Thanksgiving, diverse cultural celebration.
If Nigerians were to try halloween we would be referred to as winch. (witch).
This differences highlight the unique aspects of each culture, showcasing the beauty of diversity and understanding of understanding and appreciation.
COMMUNICATION STYLE Americans: uh hi what's your name? Nigerians: watin be your name?
Let's dive deeper GREETINGS
Americans: hey "what's up?
Nigerians: how is your family, your parents, siblings. Oya greet them for me " Nigerians love to make sure all of the family members have been asked about 🙌
FAMILY GATHERING Americans:"just me, my parents and my cat" Nigerians: "come, and meet my 50 cousins"
RELATIONSHIP In America 🇺🇸 it is normal for teenagers to be in a relationship, you can see a boy or girl alone in a room and the parent won't say shit. IN Nigeria 🇳🇬 as a teenager if you are caught with a girl or boy alone in a room, just pray to survive the night especially if your parents are warriors (they don't mess around).
IN America 🇺🇸 if a teenager tells his parents "mom dad I love him or her and I will leave the house if you don't allow us to be" the parent will allow them. IN Nigeria 🇳🇬, Tell them you are in love with your lover, and if they don't allow you to be together you will leave the house their response will be shocking even to you 😂😂 the child.
Americans 🇺🇸 : they do some activities like kiss or grab whereby a guy or girl choose between to kiss or to grab a stranger in the ass. Nigerians 🇳🇬 : if you are are caught in the street, you can will be referred to as oscroh (prostitute) and will be chased away.
Americans has more liberty but in Nigeria you are always watched by your parent, parents friends or anyone at all.
But the two countries has been a lot of things in common

2025-05-28 12:00:23Sylvi the seahorse
In the coral haven of Azure Bay, a seahorse named Sylvi danced with the tides. Her tail curled around a swaying frond as she watched fish dart by. One dawn, a lost pearl rolled into her nook. Sylvi, curious, nudged it along the reef, meeting crabs and eels who shared tales of the deep. By dusk, she found its oyster home. The pearl gleamed thanks, and Sylvi twirled home, her heart light as foam.

2025-05-07 08:23:24各ノードにポリシーがある理由 → ノードの資源(CPU、帯域、メモリ)を守り、無駄な処理を避けるため
なぜポリシーがコンセンサスルールより厳しいか 1.資源の節約 コンセンサスルールは「最終的に有効かどうか」の基準だが、全トランザクションをいちいち検証して中継すると資源が枯渇する。 ポリシーで「最初から弾く」仕組みが必要。
-
ネットワーク健全性の維持 手数料が低い、複雑すぎる、標準でないスクリプトのトランザクションが大量に流れると、全体のネットワークが重くなる。 これを防ぐためにノードは独自のポリシーで中継制限。
-
開発の柔軟性 ポリシーはソフトウェアアップデートで柔軟に変えられるが、コンセンサスルールは変えるとハードフォークの危険がある。 ポリシーを厳しくすることで、安全に新しい制限を試すことができる。
標準ポリシーの意味は何か? ノードオペレーターは自分でbitcoindの設定やコードを書き換えて独自のポリシーを使える。 理論上ポリシーは「任意」で、標準ポリシー(Bitcoin Coreが提供するポリシー)は単なるデフォルト値。 ただし、標準ポリシーには以下の大事な意味がある。
-
ネットワークの互換性を保つ基準 みんなが全く自由なポリシーを使うとトランザクションの伝播効率が落ちる。 標準ポリシーは「大多数のノードに中継される最小基準」を提供し、それを守ればネットワークに流せるという共通の期待値になる。
-
開発・サービスの指針 ウォレット開発者やサービス提供者(取引所・支払いサービスなど)は、「標準ポリシーに準拠したトランザクションを作れば十分」という前提で開発できる。 もし標準がなければ全ノードの個別ポリシーを調査しないと流れるトランザクションを作れなくなる。
-
コミュニティの合意形成の場 標準ポリシーはBitcoin Coreの開発・議論で決まる。ここで新しい制限や緩和を入れれば、まずポリシーレベルで試せる。 問題がなければ、将来のコンセンサスルールに昇格させる議論の土台になる。
つまりデフォルトだけど重要。 確かに標準ポリシーは技術的には「デフォルト値」にすぎないが、実際にはネットワークの安定・互換性・開発指針の柱として重要な役割を果たす。
ビットコインノードにおける「無駄な処理」というのは、主に次のようなものを指す。 1. 承認される見込みのないトランザクションの検証 例: 手数料が極端に低く、マイナーが絶対にブロックに入れないようなトランザクション → これをいちいち署名検証したり、メモリプールに載せるのはCPU・RAMの無駄。
-
明らかに標準外のスクリプトや形式の検証 例: 極端に複雑・非標準なスクリプト(non-standard script) → コンセンサス的には有効だが、ネットワークの他ノードが中継しないため、無駄な伝播になる。
-
スパム的な大量トランザクションの処理 例: 攻撃者が極小手数料のトランザクションを大量に送り、メモリプールを膨張させる場合 → メモリやディスクI/O、帯域の消費が無駄になる。
-
明らかに無効なブロックの詳細検証 例: サイズが大きすぎるブロック、難易度条件を満たさないブロック → 早期に弾かないと、全トランザクション検証や署名検証で計算資源を浪費する。
これらの無駄な処理は、ノードの CPU時間・メモリ・ディスクI/O・帯域 を消耗させ、最悪の場合は DoS攻撃(サービス妨害攻撃) に悪用される。 そこでポリシーによって、最初の受信段階、または中継段階でそもそも検証・保存・転送しないように制限する。 まとめると、「無駄な処理」とはネットワークの大勢に受け入れられず、ブロックに取り込まれないトランザクションやブロックにノード資源を使うこと。
無駄な処理かどうかは、単に「ポリシーで禁止されているか」で決まるわけではない。
本質的には次の2つで判断される 1. ノードの資源(CPU、メモリ、帯域、ディスク)を過剰に使うか 2. 他のノード・ネットワーク・マイナーに受け入れられる見込みがあるか
将来のBitcoin CoreのバージョンでOP_RETURNの出力数制限やデータサイズ制限が撤廃されたとする。 この場合標準ポリシー的には通るので、中継・保存されやすくなる。 しかし、他のノードやマイナーが追随しなければ意味がない。大量に流せばやはりDoS・スパム扱いされ、無駄な資源消費になる。
最終的には、ネットワーク全体の運用実態。 標準ポリシーの撤廃だけでは、「無駄な処理ではない」とは断定できない。 実質的な「無駄な処理」の判定は、技術的制約+経済的・運用的現実のセットで決まる。

2025-05-28 10:30:32Deutschland ist eines der wenigen Länder mit einer gesetzlich verankerten ausnahmslosen Schulbesuchspflicht. Mit den Schulschließungen in der Corona-Zeit wurde das Gesetz jedoch faktisch plötzlich außer Kraft gesetzt. Alle mussten zu Hause lernen. Als die Schulen danach wieder offen waren, wurden die Kinder mit Maskenpflicht, Tests und Impfdruck gequält. Nicht selten traten bei den Schülern Krankheiten und psychische Störungen auf. Nicht wenige Eltern suchten im Gespräch mit dem Lehrerkollegium nach Lösungen für ihre Kinder. In den meisten Fällen war das nicht möglich. Die Lehrer waren auf die neue Ideologie und die Durchsetzung der Maßnahmen eingeschworen und hatten Angst. Einige Eltern haben ihre Kinder dann in eigener Verantwortung aus der Schule genommen und zu Hause selbst unterrichtet. An manchen Orten fanden sich Gemeinschaften, wo die Kinder in Gruppen lernten. Während viele Lerngemeinschaften nicht mehr existieren, hat die Familie von Katharina den Unterricht für ihre drei Kinder in Eigenregie etabliert. Inzwischen haben sie dafür sogar „den Segen“ von Familiengericht und Jugendamt.
Katharina und Johannes leben mit ihren drei Wunschkindern Aurelius (15), Benjamin (14) und Friedrich (10) in einem Vorort von Leipzig. Die Familie wohnte früher in der Stadt. In der Corona-Zeit haben sie sich mit dem Physiotherapie- & Seminarzentrum Curasanus eine Existenz auf dem Land aufgebaut und begehen diesen Sommer ihr 20-jähriges Praxis-Jubiläum. Katharina hat ihre Arbeit als Physiotherapeutin weitgehend aufgegeben, um sich als Mama und Lernbegleiterin ihren Kindern widmen zu können. Daneben bietet sie Vorträge und Workshops an, übernimmt einen großen Teil der Praxis-Organisation und ist Manager, Rezeptionistin und Vertriebler der eigenen Firma. Wir besuchten einen ihrer Lachyoga-Kurse. Dabei erlebten wir ihr Zusammenspiel mit den drei Kindern. Anschließend stellten wir Katharina unsere Fragen zum Freilernen.
Im unmittelbaren Umfeld wird die Familie bestaunt und geachtet. Sie haben sich bewusst für das Freilernen entschieden. Die Kinder wurden ohne Test nicht mehr in die Schule gelassen. Auch andere Zwangsmaßnahmen wie die Maske wollten die Eltern den Kindern ersparen. Besonders Benjamin hatte traumatische Erlebnisse. Seine Lehrerin schmiss mit dem Schlüssel nach den Schülern und wandte andere schwarze Pädagogik an. Er ging ständig mit Bauchschmerzen ins Bett. Ein weiterer Punkt ist die Masernimpfung. Die Kinder könnten zwar zur Schule gehen, aber die Eltern werden mit rechtlichen Maßnahmen und Zwangszahlungen belegt. Da Katharina in ihrer Praxis viele Erkrankungen als Folge der Masernimpfung beobachten konnte, lehnt sie die Pflichtimpfung ab. Die Eltern haben kein Vertrauen mehr in die staatliche Schulerziehung mit all dem Zwang und den Erpressungen. Als die Familie den Entschluss gefasst hatte, die Kinder nicht mehr in die Schule zu schicken, haben sie ihre Praxis vorübergehend geschlossen, ihr Haus verkauft und sind auf Reisen gegangen. Die beiden großen Kinder wurden von der Schule abgemeldet. Nach der Rückkehr haben sie dann mit einem neuen Leben auf dem Land begonnen.
Lernen ohne Schule: Wie geht das?
„Wissen ist Macht und eine Holschuld“, sagt uns Katharina. Das ist ihr Motto und motiviert auch die Kinder. Mit dem Unterricht zu Hause macht die Familie ihre eigene Studie und zeigt, dass Lernen auch anders geht als in der Schule. Die Eltern können viel besser auf jedes einzelne Kind eingehen. Johannes arbeitete früher als Straßenbauer. Er unterstützt die Jungs vor allem in Mathematik, Geometrie und Physik sowie bei handwerklichen Fertigkeiten. Katharinas Stärken liegen in Deutsch, Sprachen und Organisation. Unter den Patienten ihrer Praxis gibt es Lehrer, die ihnen helfen. Weitere Unterstützung kommt von Freunden und Bekannten. Bei bestimmten Projekten treffen sie auf andere Freilernerkinder. „Das Netzwerk wird immer größer, es wird immer schöner und interessanter“, sagt Katharina. Man geht mit vielen anderen einen gemeinsamen Weg, verlässt dabei eingetretene Pfade und erkundet neue Themenfelder wie Mediengestaltung, freie Energie, Elektrotherapie, meditatives und Improvisations-Zeichnen. „Ich sprudele vor Ideen. Sie kommen in mein Feld, und dann mache ich was draus“, sagt Katharina. Die Jungs sind in Wurzen im Ringelnatz-Literaturkreis. Dort schreiben sie Drehbuchgeschichten und haben einen Film produziert. Sie suchen sich Projekte oder kreieren neue, wie mit dem Planetarium Eilenburg. Diese Zusammenarbeit hat sich sehr gut entwickelt. Dort lernen 4- bis 15-Jährige zusammen. Die drei Jungs spielen Klavier. Erdkunde und Geschichte erleben die Kinder auch dadurch, dass die Familie Hauptstädte oder die bosnischen Pyramiden selbst erkundet. Dabei erweist es sich als Vorteil, nicht auf die Ferienzeiten angewiesen zu sein.
Als Physiotherapeutin ist Katharina bewusst, dass man neue Lernstrategien entwickeln muss. Die Kinder lernen unterschiedlich. Jedes Kind hat seinen eigenen Charakter. Aurelius benötigt eher eine 1:1-Betreuung. Darauf kann Katharina viel individueller eingehen als die staatliche Schule. Es ist aber auch aufwendiger und anstrengender. Besonderen Wert legt sie darauf, dass rechte und linke Gehirnhälfte gleichmäßig beansprucht werden. Lernphasen werden immer wieder mit Entspannungs- oder Bewegungsphasen kombiniert. Sie weiß, dass den Kindern zuerst die Grundlagen des Lesens, Rechnens und Schreibens vermittelt werden müssen. Dann sind sie in der Lage, sich alles Weitere selbst anzueignen – Unterstützung vorausgesetzt. „Besonders das Schreiben mit der eigenen Hand ist wichtig für die Vernetzung der beiden Gehirnhälften“, sagt Katharina. Dafür nehmen sich die Eltern Zeit. Die Kinder führen Tagebuch. Außerdem halten es die Eltern für wichtig, den Kindern Werte und Tugenden wie Dankbarkeit, Verlässlichkeit, Beharrlichkeit, Aufrichtigkeit, Ehrlichkeit und die zehn Gebote zu vermitteln. Katharina und Johannes sind beide religiös begleitet aufgewachsen. Heute sehen sie die Kirche als Institution kritisch. Angebunden an die Schöpfung und im Gottvertrauen erschaffen und schöpfen sie Leben und Lebensraum aus eigener Kraft – so erklärt es uns Katharina.
Ein weiteres Thema sind die Funktionen des Körpers und wie sich die Kinder gesund erhalten können. Vieles lernen sie dabei in der Physiotherapiepraxis. Die Familie hat das Privileg, in ihrem eigenen Biorhythmus leben zu können. „Das macht sehr viel aus – wir sind alle gesund“, sagt Katharina. Der Lern- und Arbeitstag beginnt nicht vor 9 Uhr und hat eine eigene Struktur. Im Tagesablauf sind feste Verantwortlichkeiten integriert. So wechseln sich die Kinder aller drei Tage mit Tischdecken, Staubsaugen und Geschirrspüler ab. Das hilft ihnen, sich selbst zu organisieren. Das geht nicht immer reibungslos vonstatten. Wenn das Lernpensum beizeiten abgearbeitet wurde, helfen die Kinder im Haushalt oder Garten oder gehen ihrem Bewegungsdrang auf andere Weise nach. Die Eltern sind am Abend noch länger aktiv, denn die Praxis erfordert noch die eine oder andere bürokratische Pflicht. Die Familie ist sehr naturverbunden. Sie gehen viel in den Wald und in den Garten. Sie bauen selbst Gemüse und Obst an. Dabei können die Kinder zum Beispiel Erfahrungen mit Permakultur und natürlicher Düngung sammeln. Die Familie achtet auf die Ernährung, schließlich ist Katharina seit fast 25 Jahren Ernährungsberaterin. Was sie nicht selbst anbauen, wird beim Bauern des Vertrauens eingekauft. Die Jungs können selbst kochen und backen. Die Schädlichkeit von Zucker ist den Kindern schon bewusst geworden, ohne gänzlich auf Schokolade verzichten zu müssen. Medikamente gibt es im Haushalt nicht. Sie kennen sich sehr gut mit den Heilmitteln aus der Natur aus und können so ihre Selbstheilungskräfte aktivieren. Sie haben keinen Hausarzt. Natürlich hat keines der Kinder ein Handy. Bisher haben sie noch kein Verlangen danach. Die Eltern halten es für wichtig, dass die Kinder erst sicher bei Selbstorganisation und Tagesstruktur sind, bevor sie ein Handy bekommen. Katharina weist darauf hin, dass beispielsweise WhatsApp erst ab 16 Jahren zugelassen ist, und fragt sich, ob das andere Eltern wissen.
Gesetze auf Augenhöhe auslegen
Den Behörden blieben die Freilerner nicht verborgen. Sie wurden aktiv und schalteten das Familiengericht ein. Die Familie hatte keinen Anwalt und keine Rechtsschutzversicherung. Katharina erzählt uns, dass sie schließlich auf „Hilfe von oben“ gehofft habe. Irgendwer hat sie anscheinend erhört, denn sie bekamen „einen Engel“ als Verfahrensbeistand. Die Behörden waren sehr zugänglich. In den Gesprächen gab man zu, mit der Schulsituation ebenfalls nicht zufrieden zu sein. „Wir wollen so wie ihr, dass sich etwas verändert. Wir sind an Eurer Seite.“ Die Gespräche mit dem Jugendamt und der Richterin vom Familiengericht Grimma waren immer auf Augenhöhe. Schließlich legte man der Familie keine Steine in den Weg. Damit kann Katharina ihr Konzept nach außen leben und andere inspirieren. Ihre Schlussfolgerung: Eltern müssen sich ihrer Stärken bewusst werden und aus ihrer Angst herauskommen. Das Konzept muss aber zur Familie passen, denn jede Familie ist anders.
Die Basis für freies Lernen ist das Vertrauen der Eltern in ihre Kinder. Denn Kinder sind von Natur aus wissbegierig und wollen lernen. Katharina hat viel von Bertrand Stern und von Riccardo Leppe gelernt. Beiden wurde von ihren Eltern das Lernen ohne Schulbesuch ermöglicht. Mit Bertrand Stern hat Katharina Kontakt. Er wird im November am Buß- und Bettag eine kleine Fortbildung im Therapie- und Seminarzentrum geben. Für den Vorabend ist ein Vortrag geplant. Katharina zitiert Riccardo Leppe: „Es ändert sich nur was, wenn man es selbst tut.“ Er sei sich sicher, dass der Fortschritt beim Freilernen inzwischen so weit ist, dass „die Paste nicht wieder zurück in die Tube geht“.
Der Übergang zur Berufsausbildung
Die ersten Freilernerkinder kommen jetzt in das Alter, in dem sie eine Berufsausbildung beginnen können. Aurelius und Benjamin, die beiden „Großen“, machen seit Anfang des Jahres schon erste Praktika bei ortsansässigen Handwerksbetrieben. Beide Seiten sind sehr zufrieden. Durch die Praktika, die länger dauern als im schulischen Lehrplan vorgesehen, können sich die Kinder ausprobieren. Katharina findet es interessant miterleben zu dürfen, wie auf ihre Kinder reagiert wird. Bringen sie etwas mit, das die anderen nicht haben? Denken sie anders mit? Benjamin bekam schon ein Angebot, in einem Metallbau-Betrieb stundenweise mitzuarbeiten. In den Betrieben weiß man, dass die Abschlüsse der staatlichen Schulen größtenteils das Papier nicht wert sind, auf dem sie stehen. Viele verlassen die Schule und können kaum lesen und schreiben, von Selbstorganisation ganz zu schweigen. Ein Freilerner kann eine staatliche Externen-Prüfung ablegen, um einen Haupt- oder Realschulabschluss zu erwerben. Katharina: „Für eine Ausbildung bei einem privaten Unternehmer braucht man das nicht, allein der Unternehmer entscheidet über die Aufnahme des Auszubildenden“. Außerdem stehen den jungen Leuten Privatschulen oder der zweite Bildungsweg zur Verfügung. Wenn man einen praktischen Beruf ergreift, ist es immer noch möglich, sich bis zur Hochschulreife weiterzubilden. Nach mehrjährigen Tätigkeiten kann man bei den Kammern von Industrie, Handel und Handwerk (IHK und HWK) eine Abschlussprüfung ablegen, mit der man zum Studium zugelassen werden kann. Oder man geht gleich den Weg in die Selbstständigkeit.
Frei lernen weitergedacht
Während der Coronazeit haben sich in Sachsen und speziell um Leipzig herum kleine Freilernergruppen gefunden. Die Gruppen werden aktuell zusammengeführt, um zum Beispiel gemeinsam den Mathematikunterricht zu gestalten. Besonders um Dresden herum ist die Szene noch stärker ausgeprägt. Außerdem gibt es seit mehr als 20 Jahren den Bundesverband Natürlich Lernen (BVNL). Er bietet Beratung und zentrale Veranstaltungen an.
Der Wunsch nach dem freien Lernen ohne Schulzwang ist groß. Doch die meisten Eltern wollen ihre Kinder dafür irgendwo abgeben und nicht selbst unterrichten. Katharinas größter Wunsch ist es, drei bis fünf Elternpaare zu finden, die sich in die Betreuung und Unterrichtung ihrer Kinder teilen. Das größte Hindernis dafür sieht sie in den Eltern selbst. Durch ungelöste transgenerative Konflikte und unverarbeitete Familientraumata kommen sie noch nicht in ihre eigene Kraft für ein selbstbestimmtes Leben. Viele wagen es noch nicht, ihre Erwerbstätigkeit zugunsten der Kinder einzuschränken. Katharina sieht es als große Aufgabe für sich und ihre Familie, mit dem Freilernen das Gemeinschaftsbewusstsein und gute Konfliktlösungsstrategien zu entwickeln. Sie denkt dabei bereits an ihre Enkel. Aber sie weiß auch, dass die Eltern ein sehr hohes Maß an Eigeninitiative, Motivation und Selbstdisziplin aufbringen müssen. Sie würde Eltern, die sich das noch nicht zutrauen, als Traumabegleiterin zur Verfügung stehen, für einen angemessenen Energieausgleich. Diese gegenseitige Unterstützung käme Kindern und Eltern zugute. Ebenso hält sie die Idee der Mehrgenerationenerziehung für wichtig. Dabei profitieren nicht nur die Kinder. Die Erfahrungen der älteren Menschen gehen nicht verloren, sondern werden an die jüngeren Generationen weitergegeben und machen sie resilienter. Das hilft den Eltern, ihrer Erwerbsarbeit nachzugehen und Familientraumata zu bewältigen.
Katharina ist eine starke Frau und sprüht nur so vor Energie. Selbst als wir nach 21 Uhr das Therapiezentrum verlassen, sind ihr die Anstrengungen des Tages nicht anzumerken. Sie wird nicht müde beim Sprechen. Für Fragen zum Thema Freilernen kann man sich an sie wenden.

2025-05-28 08:25:55ถ้าอยากแล้วไม่หลง มันก็อยากด้วยปัญญา ความอยากอย่างนี้ท่านเรียกว่า เป็นบารมีของตน แต่ไม่ใช่ทุกคนนะที่มีปัญญา
บางคนไม่อยากจะให้มันอยาก เพราะเข้าใจว่า การมาปฏิบัติก็เพื่อระงับความอยาก ความจริงน่ะ ถ้าหากว่าไม่มีความอยาก ก็ไม่มีข้อปฏิบัติ ไม่รู้ว่าจะทำอะไร ลองพิจารณาดูก็ได้
ทุกคน แม้องค์พระพุทธเจ้าของเราก็ตาม ที่ท่านออกมาปฏิบัติ ก็เพื่อจะให้บรรเทากิเลสทั้งหลายนั้น
แต่ว่ามันต้องอยากทำ อยากปฏิบัติ อยากให้มันสงบ และก็ไม่อยากให้มันวุ่นวาย ทั้งสองอย่างนี้ มันเป็นอุปสรรคทั้งนั้น ถ้าเราไม่มีปัญญา ไม่มีความฉลาดในการกระทำอย่างนั้น เพราะว่ามันปนกันอยู่ อยากทั้งสองอย่างนี้มันมีราคาเท่า ๆ กัน
อยากจะพ้นทุกข์มันเป็นกิเลส สำหรับคนไม่มีปัญญา อยากด้วยความโง่ ไม่อยากมันก็เป็นกิเลส เพราะไม่อยากอันนั้นมันประกอบด้วยความโง่เหมือนกัน คือทั้งอยาก ไม่อยาก ปัญญาก็ไม่มี ทั้งสองอย่างนี้ มันเป็นกามสุขัลลิกานุโยโค กับอัตตกิลมถานุโยโค ซึ่งพระพุทธองค์ของเรา ขณะที่พระองค์กำลังทรงปฏิบัติอยู่นั้น ท่านก็หลงใหลในอย่างนี้ ไม่รู้ว่าจะทำอย่างไร ท่านหาอุบายหลายประการ กว่าจะพบของสองสิ่งนี้
ทุกวันนี้เราทั้งหลายก็เหมือนกัน ทุกสิ่งทั้งสองอย่างนี้มันกวนอยู่ เราจึงเข้าสู่ทางไม่ได้ก็เพราะอันนี้ ความเป็นจริงนี้ทุกคนที่มาปฏิบัติ ก็เป็นปุถุชนมาทั้งนั้น ปุถุชนก็เต็มไปด้วยความอยาก ความอยากที่ไม่มีปัญญา อยากด้วยความหลง ไม่อยากมันก็มีโทษเหมือนกัน “ไม่อยาก” มันก็เป็นตัณหา “อยาก” มันก็เป็นตัณหาอีกเหมือนกัน
ทีนี้ นักปฏิบัติยังไม่รู้เรื่องว่า จะเอายังไงกัน เดินไปข้างหน้าก็ไม่ถูก เดินกลับไปข้างหลังก็ไม่ถูก จะหยุดก็หยุดไม่ได้เพราะมันยังอยากอยู่ มันยังหลงอยู่ มีแต่ความอยาก แต่ปัญญาไม่มี มันอยากด้วยความหลง มันก็เป็นตัณหา ถึงแม้ไม่อยาก มันก็เป็นความหลง มันก็เป็นตัณหาเหมือนกันเพราะอะไร? เพราะมันขาดปัญญา
ความเป็นจริงนั้น ธรรมะมันอยู่ตรงนั้นแหละ ตรงความอยากกับความไม่อยากนั่นแหละ แต่เราไม่มีปัญญา ก็พยายามไม่ให้อยากบ้าง เดี๋ยวก็อยากบ้าง อยากให้เป็นอย่างนั้น ไม่อยากให้เป็นอย่างนี้ ความจริงทั้งสองอย่างนี้ หรือทั้งคู่นี้มันตัวเดียวกันทั้งนั้น ไม่ใช่คนละตัว แต่เราไม่รู้เรื่องของมัน
พระพุทธเจ้าของเรา และสาวกทั้งหลายของพระองค์นั้นท่านก็อยากเหมือนกัน แต่ “อยาก” ของท่านนั้น เป็นเพียงอาการของจิตเฉย ๆ หรือ “ไม่อยาก” ของท่าน ก็เป็นเพียงอาการของจิตเฉย ๆ อีกเหมือนกัน มันวูบเดียวเท่านั้น ก็หายไปแล้ว
ดังนั้น ความอยากหรือไม่อยากนี้ มันมีอยู่ตลอดเวลาแต่สำหรับผู้มีปัญญานั้น “อยาก” ก็ไม่มีอุปาทาน “ไม่อยาก” ก็ไม่มีอุปาทาน เป็น “สักแต่ว่า” อยากหรือไม่อยากเท่านั้น ถ้าพูดตามความจริงแล้ว มันก็เป็นแต่ "อาการของจิต" อาการของจิตมันเป็นของมันอย่างนั้นเอง ถ้าเรามาตะครุบมันอยู่ใกล้ ๆ นี่มันก็เห็นชัด
ดังนั้นจึงว่า การพิจารณานั้น ไม่ใช่รู้ไปที่อื่น มันรู้ตรงนี้แหละ เหมือนชาวประมงที่ออกไปทอดแหนั่นแหละ ทอดแหออกไปถูกปลาตัวใหญ่ เจ้าของผู้ทอดแหจะคิดอย่างไร? ก็กลัว กลัวปลาจะออกจากแหไปเสีย เมื่อเป็นเช่นนั้น ใจมันก็ดิ้นรนขึ้นระวังมาก บังคับมาก ตะครุบไปตะครุบมาอยู่นั่นแหละ ประเดี๋ยวปลามันก็ออกจากแหไปเสีย เพราะไปตะครุบมันแรงเกินไป
อย่างนั้นโบราณท่านพูดถึงเรื่องอันนี้ ท่านว่าค่อย ๆ ทำมัน แต่อย่าไปห่างจากมัน นี่คือปฏิปทาของเรา ค่อย ๆ คลำมันไปเรื่อย ๆ อย่างนั้นแหละ
อย่าปล่อยมัน หรือไม่อยากรู้มัน ต้องรู้ ต้องรู้เรื่องของมัน พยายามทำมันไปเรื่อย ๆ ให้เป็นปฏิปทา ขี้เกียจเราก็ทำไม่ขี้เกียจเราก็ทำ เรียกว่าการทำการปฏิบัติ ต้องทำไปเรื่อยๆอย่างนี้
ถ้าหากว่าเราขยัน ขยันเพราะความเชื่อ มันมีศรัทธาแต่ปัญญาไม่มี ถ้าเป็นอย่างนี้ ขยันไป ๆ แล้วมันก็ไม่เกิดผลอะไรขึ้นมากมาย ขยันไปนาน ๆ เข้า แต่มันไม่ถูกทาง มันก็ไม่สงบระงับ ทีนี้ก็จะเกิดความคิดว่า เรานี้บุญน้อยหรือวาสนาน้อย หรือคิดไปว่ามนุษย์ในโลกนี้คงทำไม่ได้หรอก แล้วก็เลยหยุดเลิกทำเลิกปฏิบัติ
ถ้าเกิดความคิดอย่างนี้เมื่อใด ขอให้ระวังให้มาก ให้มีขันติ ความอดทน ให้ทำไปเรื่อย ๆ เหมือนกับเราจับปลาตัวใหญ่ ก็ให้ค่อย ๆ คลำมันไปเรื่อย ๆ ปลามันก็จะไม่ดิ้นแรงค่อย ๆทำไปเรื่อย ๆ ไม่หยุด ไม่ช้าปลาก็จะหมดกำลัง มันก็จับง่าย จับให้ถนัดมือเลย ถ้าเรารีบจนเกินไป ปลามันก็จะหนีดิ้นออกจากแหเท่านั้น
ดังนั้น การปฏิบัตินี้ ถ้าเราพิจารณาตามพื้นเหตุของเรา เช่นว่า เราไม่มีความรู้ในปริยัติ ไม่มีความรู้ในอะไรอื่น ที่จะให้การปฏิบัติมันเกิดผลขึ้น ก็ดูความรู้ที่เป็นพื้นเพเดิมของเรานั่นแหละอันนั้นก็คือ “ธรรมชาติของจิต” นี่เอง มันมีของมันอยู่แล้ว เราจะไปเรียนรู้มัน มันก็มีอยู่ หรือเราจะไม่ไปเรียนรู้มัน มันก็มีอยู่
อย่างที่ท่านพูดว่า พระพุทธเจ้าจะบังเกิดขึ้นก็ตาม หรือไม่บังเกิดขึ้นก็ตาม ธรรมะก็คงมีอยู่อย่างนั้น มันเป็นของมันอยู่อย่างนั้น ไม่พลิกแพลงไปไหน มันเป็นสัจจธรรม
เราไม่เข้าใจสัจจธรรม ก็ไม่รู้ว่าสัจจธรรมเป็นอย่างไร นี้เรียกว่า การพิจารณาในความรู้ของผู้ปฏิบัติที่ไม่มีพื้นปริยัติ
ขอให้ดูจิต พยายามอ่านจิตของเจ้าของ พยายามพูดกับจิตของเจ้าของ มันจึงจะรู้เรื่องของจิต ค่อย ๆ ทำไป ถ้ายังไม่ถึงที่ของมัน มันก็ไปอยู่อย่างนั้น
ครูบาอาจารย์บางท่านบอกว่า ทำไปเรื่อย ๆ อย่าหยุด บางทีเรามาคิด “เออ ทำไปเรื่อย ๆ ถ้าไม่รู้เรื่องของมัน ถ้าทำไม่ถูกที่มัน มันจะรู้อะไร” อย่างนี้เป็นต้น ก็ต้องไปเรื่อย ๆ ก่อน แล้วมันก็จะเกิดความรู้สึกนึกคิดขึ้นในสิ่งที่เราพากเพียรทำนั้น
มันเหมือนกันกับบุรุษที่ไปสีไฟ ได้ฟังท่านบอกว่า เอาไม้ไผ่สองอันมาสีกันเข้าไปเถอะ แล้วจะมีไฟเกิดขึ้น บุรุษนั้นก็จับไม้ไผ่เข้าสองอัน สีกันเข้า แต่ใจร้อน สีไปได้หน่อย ก็อยากให้มันเป็นไฟ ใจก็เร่งอยู่เรื่อย ให้เป็นไฟเร็วๆ แต่ไฟก็ไม่เกิดสักที บุรุษนั้นก็เกิดความขี้เกียจ แล้วก็หยุดพัก แล้วจึงลองสีอีกนิด แล้วก็หยุดพัก ความร้อนที่พอมีอยู่บ้าง ก็หายไปล่ะซิ เพราะความร้อนมันไม่ติดต่อกัน
ถ้าทำไปเรื่อยๆอย่างนี้ เหนื่อยก็หยุด มีแต่เหนื่อยอย่างเดียวก็พอได้ แต่มีขี้เกียจปนเข้าด้วย เลยไปกันใหญ่ แล้วบุรุษนั้นก็หาว่าไฟไม่มี ไม่เอาไฟ ก็ทิ้ง เลิก ไม่สีอีก แล้วก็ไปเที่ยวประกาศว่า ไฟไม่มี ทำอย่างนี้ไม่ได้ ไม่มีไฟหรอก เขาได้ลองทำแล้ว
ก็จริงเหมือนกันที่ได้ทำแล้ว แต่ทำยังไม่ถึงจุดของมันคือความร้อนยังไม่สมดุลกัน ไฟมันก็เกิดขึ้นไม่ได้ ทั้งที่ความจริงไฟมันก็มีอยู่ อย่างนี้ก็เกิดความท้อแท้ขึ้นในใจของผู้ปฏิบัตินั้น ก็ละอันนี้ไปทำอันโน้นเรื่อยไป อันนี้ฉันใดก็ฉันนั้น
การปฏิบัตินั้น ปฏิบัติทางกายทางใจทั้งสองอย่าง มันต้องพร้อมกัน เพราะอะไร? เพราะพื้นเพมันเป็นคนมีกิเลสทั้งนั้น พระพุทธเจ้าก่อนที่จะเป็นพระพุทธเจ้า ท่านก็มีกิเลสแต่ท่านมีปัญญามากหลาย พระอรหันต์ก็เหมือนกัน เมื่อยังเป็นปุถุชนอยู่ ก็เหมือนกับเรา
เมื่อความอยากเกิดขึ้นมา เราก็ไม่รู้จัก เมื่อความไม่อยากเกิดขึ้นมา เราก็ไม่รู้จัก บางทีก็ร้อนใจ บางทีก็ดีใจ ถ้าใจเราไม่อยาก ก็ดีใจแบบหนึ่ง และวุ่นวายอีกแบบหนึ่ง ถ้าใจเราอยาก มันก็วุ่นวายอย่างหนึ่ง และดีใจอย่างหนึ่ง มันประสมประเสกันอยู่อย่างนี้
อันนี้คือปฏิปทาของผู้ปฏิบัติเรา

I know some of our stackers are follicly challenged, so I thought I'd pass along this video.
Have any of you tried topical onion juice for hair regrowth?
I'll eat more onion and rosemary and get more Sun, just to be safe.

2025-05-03 21:54:45Introduction
Me and Fishcake have been working on infrastructure for Noswhere and Nostr.build. Part of this involves processing a large amount of Nostr events for features such as search, analytics, and feeds.
I have been recently developing
nosdex
v3, a newer version of the Noswhere scraper that is designed for maximum performance and fault tolerance using FoundationDB (FDB).Fishcake has been working on a processing system for Nostr events to use with NB, based off of Cloudflare (CF) Pipelines, which is a relatively new beta product. This evening, we put it all to the test.
First preparations
We set up a new CF Pipelines endpoint, and I implemented a basic importer that took data from the
nosdex
database. This was quite slow, as it did HTTP requests synchronously, but worked as a good smoke test.Asynchronous indexing
I implemented a high-contention queue system designed for highly parallel indexing operations, built using FDB, that supports: - Fully customizable batch sizes - Per-index queues - Hundreds of parallel consumers - Automatic retry logic using lease expiration
When the scraper first gets an event, it will process it and eventually write it to the blob store and FDB. Each new event is appended to the event log.
On the indexing side, a
Queuer
will read the event log, and batch events (usually 2K-5K events) into one work job. This work job contains: - A range in the log to index - Which target this job is intended for - The size of the job and some other metadataEach job has an associated leasing state, which is used to handle retries and prioritization, and ensure no duplication of work.
Several
Worker
s monitor the index queue (up to 128) and wait for new jobs that are available to lease.Once a suitable job is found, the worker acquires a lease on the job and reads the relevant events from FDB and the blob store.
Depending on the indexing type, the job will be processed in one of a number of ways, and then marked as completed or returned for retries.
In this case, the event is also forwarded to CF Pipelines.
Trying it out
The first attempt did not go well. I found a bug in the high-contention indexer that led to frequent transaction conflicts. This was easily solved by correcting an incorrectly set parameter.
We also found there were other issues in the indexer, such as an insufficient amount of threads, and a suspicious decrease in the speed of the
Queuer
during processing of queued jobs.Along with fixing these issues, I also implemented other optimizations, such as deprioritizing
Worker
DB accesses, and increasing the batch size.To fix the degraded
Queuer
performance, I ran the backfill job by itself, and then started indexing after it had completed.Bottlenecks, bottlenecks everywhere
After implementing these fixes, there was an interesting problem: The DB couldn't go over 80K reads per second. I had encountered this limit during load testing for the scraper and other FDB benchmarks.
As I suspected, this was a client thread limitation, as one thread seemed to be using high amounts of CPU. To overcome this, I created a new client instance for each
Worker
.After investigating, I discovered that the Go FoundationDB client cached the database connection. This meant all attempts to create separate DB connections ended up being useless.
Using
OpenWithConnectionString
partially resolved this issue. (This also had benefits for service-discovery based connection configuration.)To be able to fully support multi-threading, I needed to enabled the FDB multi-client feature. Enabling it also allowed easier upgrades across DB versions, as FDB clients are incompatible across versions:
FDB_NETWORK_OPTION_EXTERNAL_CLIENT_LIBRARY="/lib/libfdb_c.so"
FDB_NETWORK_OPTION_CLIENT_THREADS_PER_VERSION="16"
Breaking the 100K/s reads barrier
After implementing support for the multi-threaded client, we were able to get over 100K reads per second.
You may notice after the restart (gap) the performance dropped. This was caused by several bugs: 1. When creating the CF Pipelines endpoint, we did not specify a region. The automatically selected region was far away from the server. 2. The amount of shards were not sufficient, so we increased them. 3. The client overloaded a few HTTP/2 connections with too many requests.
I implemented a feature to assign each
Worker
its own HTTP client, fixing the 3rd issue. We also moved the entire storage region to West Europe to be closer to the servers.After these changes, we were able to easily push over 200K reads/s, mostly limited by missing optimizations:
It's shards all the way down
While testing, we also noticed another issue: At certain times, a pipeline would get overloaded, stalling requests for seconds at a time. This prevented all forward progress on the
Worker
s.We solved this by having multiple pipelines: A primary pipeline meant to be for standard load, with moderate batching duration and less shards, and high-throughput pipelines with more shards.
Each
Worker
is assigned a pipeline on startup, and if one pipeline stalls, other workers can continue making progress and saturate the DB.The stress test
After making sure everything was ready for the import, we cleared all data, and started the import.
The entire import lasted 20 minutes between 01:44 UTC and 02:04 UTC, reaching a peak of: - 0.25M requests per second - 0.6M keys read per second - 140MB/s reads from DB - 2Gbps of network throughput
FoundationDB ran smoothly during this test, with: - Read times under 2ms - Zero conflicting transactions - No overloaded servers
CF Pipelines held up well, delivering batches to R2 without any issues, while reaching its maximum possible throughput.
Finishing notes
Me and Fishcake have been building infrastructure around scaling Nostr, from media, to relays, to content indexing. We consistently work on improving scalability, resiliency and stability, even outside these posts.
Many things, including what you see here, are already a part of Nostr.build, Noswhere and NFDB, and many other changes are being implemented every day.

2025-05-28 05:54:01** Introduction: The Neon Pulse of Las Vegas
**It’s 2:30 AM on a Tuesday. The Strip hums with laughter, clinking glasses, and the occasional Elvis impersonator. A group of friends stumbles out of a nightclub, squinting under the glow of a Las Vegas billboard that screams, “Hungry? $5 Pancakes → 1 Block Right!” Ten minutes later, they’re drowning their late-night cravings in syrup.This isn’t luck—it’s Las Vegas billboards doing what they do best: working while the rest of the world sleeps. In a city where the party never stops, these glowing giants are the ultimate salespeople. Let’s dive into why Las Vegas billboards outshine traditional ads and how your business can ride their 24/7 energy wave.
** Why Las Vegas Billboards Never Take a Coffee Break
** 1. Tourists Don’t Have Bedtimes (and Neither Do Billboards)
- 42 million visitors flock to Vegas yearly. They’re sipping margaritas at noon, gambling at midnight, and shopping at 3 AM.
- Las Vegas billboards near hotspots like the Bellagio Fountains or Fremont Street catch eyes round the clock.Real Story:
A donut shop owner named Luis rented a billboard near the “Welcome to Vegas” sign. His message? “Jet Lagged? Sugar Fix Open 24/7!” Sales tripled—especially between 1 AM and 4 AM.** 2. You Can’t “Skip” a Billboard
** - Imagine this: You’re stuck in traffic on the Strip. Your phone’s dead. That Las Vegas billboard for air-conditioned massages? It’s your lifeline.
- Compare that to online ads: 47% of people skip them, and TikTok ads vanish in a scroll.- Vegas Thrives on Impulse
- Billboards tap into spontaneous decisions:
- “Let’s try that rooftop bar!”
- “Wait, free slot play? Let’s U-turn!”
- Traditional ads (like radio spots) fade fast. Billboards linger, nudging tourists to act now.
** 5 Reasons Your Business Needs a Vegas Billboard
** 1. Size Matters (And So Does Flash)
- Strip billboards can be taller than a 5-story building.
- Digital screens use LEDs so bright, they’re visible from space.Pro Tip:
A casino added fake “smoke” effects to their billboard for a Halloween promo. Traffic backed up for selfies—and bookings spiked.- No Language Barrier
- Vegas draws visitors from Tokyo, Berlin, São Paulo...
- A Las Vegas billboard with a giant cocktail emoji? Universal for “Drinks here!”
Case Study:
A Korean BBQ spot used a billboard of sizzling meat. No words. Just smoke visuals. Tourists followed the “aroma” straight to their door.- They’re Always in the Right Place, Right Time
- 6 AM: Joggers see smoothie ads.
- 3 PM: Pool partiers spot “Free Margarita” promos.
-
Midnight: Hangover clinics whisper, “We’ve got IVs.”
-
Instant Trust Boost
- A tiny online ad says “startup.” A glowing billboard says, “We’re Vegas royalty.”
Jake’s Win:
Jake’s tiny magic shop rented a billboard reading, “Real Tricks—Cheaper Than the Casino!” Tourists treated him like David Blaine.- QR Codes = Instant Customers
- “Scan for free parking!” → 1,000 scans in a weekend.
- “Tap to call a limo” → Rides booked before the light turns green.
** How to Make Your Vegas Billboard Irresistible
** Step 1: Claim Your Territory
- The Strip: Pricey but prime ($15k–$60k/month).
- Fremont Street: Quirky, cheaper ($5k–$20k), packed with partiers.
- Highway 15: Target road-trippers with “Almost There! Cold Beer Ahead!”Step 2: Keep It Stupid Simple
- Bad: “Experience Culinary Excellence at Our Artisanal Bistro!”
- Good: “24/7 Bacon Pancakes → Exit Here.”Maria’s Hack:
Maria’s tattoo parlor used a billboard with a flaming skull and three words: “Walk-Ins Welcome.” No phone number. “People just… show up,” she laughs.Step 3: Track Your Wins (Like a Vegas High Roller)
- QR Codes: “Scan for Free Slot Play!” → Track scans.
- Unique URLs: “Visit VegasPizza24.com” → Monitor traffic.
- Old-School: Count foot traffic. (“Did that bachelor party just roll in from our billboard? Yes.”)**FAQs ** 1. “How do I even measure if my billboard’s working? It’s not like online ads!”
Answer:
You’re right—it’s not just clicks and likes. But here’s how real businesses track success:
- QR Codes: Add a unique code like “Scan for Free Appetizer!” Track scans.
- Promo Codes: “Mention this billboard for 20% off!” (Works great for Uber drivers: “My passengers blurt it out mid-ride,” says driver Luis M.)
- Foot Traffic Spikes: Note sales surges after your ad goes live. A dispensary saw a 60% bump in visits after their “We’re Closer Than the Casino!” billboard.
- Social Media Tags: Encourage selfies with your billboard. A retro motel offered a free pool pass for tagged photos. Their Instagram exploded.- “Aren’t billboards old-school? My Gen Z customers live on TikTok!”
Answer:
Billboards in Vegas are anything but old-school. Here’s why: - Hybrid Campaigns: Pair billboards with geofenced mobile ads. Example: A billboard for a pool party says, “Scan to Pre-Order Drinks.” Users nearby get a TikTok-style ad on their phone.
- Instagrammable Designs: Quirky billboards go viral. The “Welcome to Vegas” sign is the most Instagrammed spot in the city. Mimic that vibe!
- Influencer Collabs: Pay a Vegas influencer to pose with your billboard. Their followers will hunt it down like a scavenger hunt.
Real Story:
A vintage clothing store’s billboard (“Find Your Retro Vibe → 2 Blocks East”) became a TikTok trend after a local influencer did a “thrift haul” video there.** 3. “What’s the biggest mistake businesses make with Vegas billboards?”
** Answer:
Trying to cram in too much info! Drivers have 5–7 seconds to read your ad. Avoid:
- Text Overload: “Grand Opening! 50% Off! Open 24/7! Call Now!” → Too much!
- Bland Designs: Gray text on a gray background? Yawn.
- Ignoring Locals: Tourists are 70% of viewers, but locals matter too. A gym’s billboard said, “Tired of Tourists? Work Out in Peace.” Memberships spiked.Fix It:
- Use 7 words max.
- Bold colors (red, yellow, neon pink).
- Add a clear call to action: “Turn Right Now!” or “Scan for Free Parking.”- “Do I need a permit? What if my ad gets rejected?”
Answer:
Yep, permits are a thing. The city bans: - Flashing Lights Near Residences: No strobes in suburban areas.
- Certain Content: No swear words, adult themes, or political fights.
How to Avoid Rejection:
- Work with local Outdoor Advertising companies—they know the rules.
- Submit designs early. One pizza joint’s ad was flagged for a pepperoni slice deemed “too suggestive.” They swapped it to a cheese pull… and it got approved.Conclusion: Let Your Business Shine All Night Long
At 5 AM, as the sun peeks over the desert, the Las Vegas billboards keep glowing. They’ve sold midnight pancakes, inspired shotgun weddings, and even talked someone out of a questionable tattoo (“Wait! Our Parlor’s Better → Next Exit”).These aren’t just ads—they’re part of Vegas’ heartbeat. So whether you’re slinging sushi, massages, or monster truck rides, remember: In a city that never sleeps, your billboard shouldn’t either.
Ready to Light Up the Night?
Find Las Vegas billboards near you today. And if you spot one that says, “Free High-Fives for Readers of This Article,” honk twice. It’s probably yours. -

2025-05-28 12:21:32In a world that constantly demands our attention, where external achievements are often mistaken for fulfillment, there is a quieter, more powerful path to freedom—the journey within. True freedom is not merely the absence of constraints but the presence of inner peace, purpose, and self-mastery.
What Is Self-Mastery?
Self-mastery is the ability to govern your thoughts, emotions, and actions in alignment with your values and goals. It is about becoming the author of your own story rather than being swept away by the noise and chaos of the external world. With self-mastery comes clarity, direction, and the freedom to live authentically.
The Pillars of Inner Freedom
-
Self-Awareness: Freedom begins with knowing who you are. Understanding your strengths, triggers, and motivations lays the foundation for personal growth.
-
Discipline: Discipline is not restriction—it is the structure that supports your vision. It turns intention into reality.
-
Emotional Intelligence: Learning to manage emotions, rather than being ruled by them, grants the power to respond rather than react.
-
Purpose: A sense of purpose provides direction. When you know what matters most, distractions lose their power.
Why Self-Mastery Matters
Without self-mastery, external freedom can feel hollow. You might have opportunities, resources, and rights, yet still feel trapped—by fear, self-doubt, or the need for validation. Mastering yourself unlocks the kind of freedom that no one can take away: the freedom to be at peace with who you are.
How to Begin the Journey
-
Reflect Daily: Spend time each day in silence or journaling to deepen your awareness.
-
Set Intentions: Start each day with a clear intention to guide your focus.
-
Challenge Yourself: Growth lies just beyond your comfort zone. Embrace discomfort as part of the process.
-
Seek Stillness: Create moments of stillness to listen to your inner voice.
“He who conquers himself is the mightiest warrior.” — Confucius
True freedom starts from within. Master yourself, and you master your life.

今までbtcpayのposでしたが速度を追求してこれに変更しました。 たまに上手くいかないですがそしたら渋々POS出すので温かい目でよろしくお願いします。
ノードを建てたり決済したりで1年経ちました。 最近も少しずつノードを建てる方が増えてるみたいで本当凄いですねUmbrel 大体の人がルーティングに果敢に挑むのを見つつ 奥さんに土下座しながら費用を捻出する弱小の私は決済の利便性を全開で振り切るしか無いので応援よろしくお願いします。
あえて あえて言うのであれば、ルーティングも楽しいですけど やはり本当の意味での即時決済や相手を選んでチャネルを繋げる楽しさもあるよとお伝えしたいっ!! 決済を受け入れないと分からない所ですが 承認がいらない時点で画期的です。
QRでもタッチでも金額指定でも入力でも もうやりようには出来てしまうし進化が恐ろしく早いので1番利用の多いpaypayの手数料(事業者側のね)を考えたらビットコイン凄いじゃない!と叫びたくなる。 が、やはり税制面や価格の変動(うちはBTC固定だけども)ウォレットの操作や普及率を考えるとまぁ難しい所もあるんですかね。
それでも継続的に沢山の人が色んな活動をしてるので私も何か出来ることがあれば 今後も奥さんに土下座しながら頑張って行きたいと思います。

Ethereum 0.0039 ETH (zkSync) “39” sounds like “thank you” in Japanese. Prices aren’t pegged to yen.These days I’m open only once a week. On other days I’m out scouting new spots for the kitchen-car. If you know weekday-lunch locations inside Tokyo where I could set up, please let me know!
The photo shows an NFC tag. If your phone has a Lightning wallet, just tap and pay 3,900 sats. I admit this hand-written NFC tag looks shady—any self-respecting Bitcoiner probably wouldn’t want to tap it—but the point is: even this works!
I used to run a BTCPay POS, but I switched to this setup for speed. Sometimes the tap payment fails; if that happens I reluctantly pull out the old POS. Thanks for your patience.
It’s been one year since I spun up a node and started accepting Lightning payments. So many people are now running their own nodes—Umbrel really is amazing. While the big players bravely chase routing fees, I’m a tiny operator scraping together funds while begging my wife for forgiveness, so I’m all-in on maximising payment convenience. Your support means a lot!
If I may add: routing is fun, but instant, trust-minimised payments and the thrill of choosing whom to open channels with are just as exciting. You’ll only understand once you start accepting payments yourself—zero-confirmation settlement really is revolutionary.
QR codes, NFC taps, fixed amounts, manual entry… the possibilities keep multiplying, and the pace of innovation is scary fast. When I compare it to the merchant fees on Japan’s most-used service, PayPay, I want to shout: “Bitcoin is incredible!” Sure, taxes, price volatility (my shop is BTC-denominated, though), wallet UX, and adoption hurdles are still pain points.
Even so, lots of people keep building cool stuff, so I’ll keep doing what I can—still on my knees to my wife, but moving forward!

2025-05-28 04:34:08Ascolta bene! It is more dignified to thirst alone in the desert than to share wine with someone who has no thirst for conquest.
On the silent path to success, it’s not the declared enemies who slow the march, but rather the friends. Not the noble or loyal ones, but the failures—those who carry a dull glint in their eyes, chronic laziness in their spirit, and the eternal excuse of bad luck in their pockets. Friendship, when poorly chosen, becomes a polished anchor, tied to your ankle with ropes named camaraderie.
Nothing weighs heavier on the journey than having to endure the failed and envious around you. It is a kind of emotional parasitism that begins with empathy and ends in stagnation. Those who live among the weak will crawl. Those who keep company with miserable friends, instead of striving to prosper, learn to curse wealth—not out of ethics, but out of envy. Mediocrity, my friend, is contagious. And it does not take root suddenly, but like a silent epidemic.
Ambition—that fire that burns in the bones of great men—will always seem like arrogance to the ears of the failed. Those who have never built anything, except arguments to justify their paralysis, will never understand the fury of someone born to conquer. And so, with smiles, they spit venom: “Calm down,” they say, “be content,” they advise. Hypocrites. What they call humility is nothing more than resignation to their own defeat.
To walk alone, with hunger and honor, is worth more than feasting at lavish tables at the cost of your own sweat, surrounded by parasites who toast your downfall with glasses full of praise. No one prospers where the conversation is filled with complaints, criticism, and envy. What does not build up, corrodes.
The rust of the weak is invisible at first—a bitter joke here, a veiled critique there. And before you know it, the structure is already rotten. Of the friendship, only the weight remains. Of the relationship, only exhaustion. The true enemy of success is the company of those who have failed and wish for you the same fate. These tragic figures—always tired, always victims—are masters of collective self-sabotage.
Feel no remorse in abandoning those who build nothing and consume everything. And in that abandonment, you become freer, stronger, and unbreakable.
Thank you for reading, my friend!
If this message resonated with you, consider leaving your "🥃" as a token of appreciation.
A toast to our family!

Bitcoin Enters a New Era: Industry Leaders Predict Trillions in Institutional InflowsAt the 2025 Bitcoin Conference in Las Vegas, the Founder and CEO of Kelly Intelligence Kevin Kelly, the Chief Executive Officer of Bitwise Asset Management Hunter Horsley, the CEO of BitGo Mike Belshe and the Advisor of WBTC Justin Sun talked about the future of financial products in the globe.
Hunter Horsley started the panel by saying that we are entering a new chapter in 2025 with the change in the regulatory circumstances.
“In the US wealth managers manage between 30 and 60 trillion dollars,” said Horsley. “If wealth managers wind up allocating 1% to the space on behalf of their clients, helping their clients access the opportunities here that are hundreds and billions of dollars.”
JUST IN:
$12 billion Bitwise CEO Hunter Horsley says if wealth managers allocate 1% to #Bitcoin, “that's hundreds of billions of dollars.”

— Bitcoin Magazine (@BitcoinMagazine) May 27, 2025
Justin Sun emphasized the importance of integrating Bitcoin into decentralized finance (DeFi) platforms:
“Raw Bitcoin is a way to get your Bitcoin into a smart contract platform,” said Sun. “You can use your Bitcoin as collateral you borrow like stablecoin, you borrow other major crypto currencies tokens and also of course generate yield on the Bitcoin you are holding because Bitcoin is a proof of network.”
“Any transaction you can see in the blockchain and all the reserve addresses is available on the Blockchain. It’s safe and transparent and at the same time is smart,” stated Sun.
Mike Belshe elaborated on the foundational elements that make a stablecoin successful, particularly when Bitcoin is used in that context.
“What makes a good stablecoin whether you are talking about dollars or Bitcoin, it’s the liquidity that you have on the market around the world,” stated Belshe.
Horsley continued by addressing that we’ll see more companies adopting this and hundreds of thousands of Bitcoin being put onto more balance sheets.
“Corporations are buying Bitcoin,” commented Horsley. “It’s an extraordinary theme of this year. As of the first quarter of this year, 79 publicly traded companies had put Bitcoin on their balance sheet. Over 600k Bitcoin and there is only 21 million Bitcoin. It’s a lot of Bitcoin”
Justin Sun closed the panel by stating, “the progress we are making here in the United States really matters because as we all further encourage people around the world to get into the Bitcoin industry.”
“Once Bitcoin passes this kind of stage and gets institution adoption in the United States will accelerate that option globally,” said Sun.

2025-05-28 04:02:47For those who still don't truly understand Bitcoin, it means you still don't understand what money is, who creates it, and why humans need money.
It's a scam that the education system doesn't teach this important subject, while we spend almost our entire lives trying to earn money. Therefore, I recommend following the money and studying Bitcoin seriously.
Why Bitcoin Matters
Saving is the greatest discovery in human history
Before humans learned to save, we were just animals living day to day. Saving is what makes humans different from other animals — the ability to think about the future and store for later.
Saving created civilization itself
Without saving, there would be no cities, no science, no art. Everything we call "progress" comes from the ability to save.
Money is the greatest creation in human history
It is the tool that has allowed human civilization to advance to this day. Money is the best tool humans use for saving.
Bitcoin is the best money ever created
It is the most perfect money humans have ever created. No one can control, manipulate, destroy it, and it is truly limited like time in life.
Bitcoin is like a black hole
That will absorb all value from the damaged financial system. It will draw stability and value to itself. Everything of value will flow into Bitcoin eventually.
Bitcoin is like Buddhism discovering truth
It helps understand the root problems of the current financial system and the emergence of many problems in society, just like Buddha who understood all suffering and the causes of suffering.
Bitcoin is freedom
Money is power, money controls human behavior. When we have money that preserves value and cannot be controlled, we will have intellectual freedom, freedom of expression, and the power to choose.
The debt that humanity has created today would take another thousand years to pay off completely
There is no way out and it's heading toward serious collapse. Bitcoin is the light that will help prevent humanity from entering another dark age.
Bitcoin cannot steal your time
It cannot be created from nothing. Every Bitcoin requires real energy and time to create.
Bitcoin is insurance that protects against mismanagement
It helps protect against currency debasement, economic depression, and failed policies. Bitcoin will protect your value.
Bitcoin is going to absorb the world's value
Eventually, Bitcoin will become the store of value for the entire world. It will absorb wealth from all assets, all prices, and all investments.
Exit The Matrix
We live in a financial Matrix. Every day we wake up and go to work, thinking we're building a future for ourselves. But in reality, we're just giving energy to a system that extracts value from us every second. Bitcoin is the red pill — it will open your eyes to see the truth of the financial world. Central banks are the architects of this Matrix — they create money from nothing, and we have to work hard to get it.
The education system has deceived us greatly. They teach us to work for money, but never teach us what money is. We spend 12-16 years in school, then spend our entire lives earning money, but never know what it is, who creates it, and why it has value. This is the biggest scam in human history.
We are taught to be slaves of the system, but not taught to understand the system.
The Bitcoin standard will end war
When you can't print money for war anymore, war becomes too expensive.
We are entering the Bitcoin Renaissance era
An era of financial and intellectual revival. Bitcoin is creating a new class of humans. People who understand and hold Bitcoin will become a new class with true freedom.
The Path to Financial Truth
Follow the money trail and you will see the truth: - Who controls money printing? - Why do prices keep getting higher? - Why are the poor getting poorer and the rich getting richer?
All the answers lie in understanding money and Bitcoin.
Studying Bitcoin is not just about investment — it's about understanding the future of currency and human society.
Don't just work for money. Understand money. Study Bitcoin.
If you don't understand money, you will be a slave to the system forever. If you understand Bitcoin, you will gain freedom.

2025-04-29 04:04:19Umbrel Core-lightning(以下CLNと略す)を運用するにあたり役に立ちそうなノウハウやメモを随時投稿します。
・configファイルを用意する Umbrelのアプリとして必要な設定はdocker-compose.ymlで指定されている。 それ以外の設定をしたい場合configファイルに入れると便利。 configファイルの置き場所は /home/umbrel/umbrel/app-data/core-lightning/data/lightningd ここにtouch configとでもやってファイルをつくる。
cd /home/umbrel/umbrel/app-data/core-lightning/data/lightningd touch config
以下内容をひな型として使ってみてください。 行頭に#があるとコメント行になります。つまり.iniフォーマット。 /home/umbrel/umbrel/app-data/core-lightning/data/lightningd/config ```[General options]
[Bitcoin control options]
[Lightning daemon options]
[Lightning node customization options]
[Lightning channel and HTLC options]
[Payment control options]
[Networking options]
[Lightning Plugins]
[Experimental Options]
``` configに設定できる内容は以下を参照 https://lightning.readthedocs.io/lightningd-config.5.html セクションを意味する[]があるけれどもこれは私(tanakei)が意図的に見やすく区別しやすくするために付けただけ。これら行の#は外さない。
・configの設定をCLNに反映させる appスクリプトでCLNを再起動すると反映することができる。 configを書き換えただけでは反映されない。
cd /home/umbrel/umbrel/scripts ./app restart core-lightning
・ログをファイルに出力させる
以下の場所でtouch log.txtとしてlog.txtファイルを作る。 /home/umbrel/umbrel/app-data/core-lightning/data/lightningd
cd /home/umbrel/umbrel/app-data/core-lightning/data/lightningd touch log.txt
次にconfigの[Lightning daemon options]セクションにlog-fileを追加する。 ```[Lightning daemon options]
log-file=/data/.lightning/log.txt ``` ※Dockerによって/home/umbrel/umbrel/app-data/core-lightning/data/lightningd は /data/.lightning として使われている。
・addrとbind-addrの違い どちらも着信用のインターフェースとポートの設定。addrは指定したホストIPアドレス:ポート番号をノードURIに含めて公開する(node_announcementのuris)。bind-addrは公開しない。
・実験的機能のLN Offerを有効にする configの[Experimental Options]セクションに以下を追加する。 ```
[Experimental Options]
experimental-onion-messages experimental-offers ``` ※ v24.08でexperimental-onion-messageは廃止されデフォルト有効であり、上記設定の追加は不要になりました。 ※ v21.11.1 では experimental-offersは廃止されデフォルト有効であり、上記設定の追加は不要になりました。 もう実験扱いじゃなくなったのね...
・完全にTorでの発信オンリーにする UmbrelはなぜかCLNの発信をClearnetとTorのハイブリッドを許している。それは always-use-proxy=true の設定がないから。(LNDは発着信Torのみなのに) なのでこの設定をconfigに追加してCLNも発着進Torのみにする。 ```
[Networking options]
always-use-proxy=true ```
・任意のニーモニックからhsm_secretを作る CLNのhsm_secretはLNDのwallet.dbのようなもの。ノードで使う様々な鍵のマスター鍵となる。Umbrel CLNはこのhsm_secretファイルを自動生成したものを使い、これをバックアップするためのニーモニックを表示するとかそういう機能はない。自分で作って控えてあるニーモニックでhsm_secretを作ってしまえばこのファイルが壊れてもオンチェーン資金は復旧はできる。
1.CLNインストール後、dockerコンテナに入る
docker exec -it core-lightning_lightningd_1 bash
2.lightning-hsmtoolコマンドを使って独自hsm_secretを作る ``` cd data/.lightning/bitcoin lightning-hsmtool generatehsm my-hsm_secret・上記コマンドを実行するとニーモニックの言語、ニーモニック、パスフレーズの入力を催促される。 Select your language: 0) English (en) 1) Spanish (es) 2) French (fr) 3) Italian (it) 4) Japanese (jp) 5) Chinese Simplified (zhs) 6) Chinese Traditional (zht) Select [0-7]: 0 ※定番の英単語なら0を入力 Introduce your BIP39 word list separated by space (at least 12 words): <ニーモニックを入力する> Warning: remember that different passphrases yield different bitcoin wallets. If left empty, no password is used (echo is disabled). Enter your passphrase: <パスフレーズを入力する> ※パスフレーズ不要ならそのままエンターキーを押す。 New hsm_secret file created at my-hsm_secret Use the
encrypt
command to encrypt the BIP32 seed if neededコンテナから抜ける exit
3.appスクリプトでCLNを止めて、独自hsm_secret以外を削除 ※【重要】いままで使っていたhsm_secretを削除する。もしチャネル残高、ウォレット残高があるならチャネルを閉じて資金を退避すること。自己責任!
cd ~/umbrel/scripts/ ./app stop core-lightningcd ~/umbrel/app-data/core-lightning/data/lightningd/bitcoin rm gossip_store hsm_secret lightningd.sqlite3 lightning-rpc mv my-hsm_secret hsm_secret
4.appスクリプトでCLNを再開する
cd ~/umbrel/scripts/ ./app start core-lightning ```【補記】 hsm_secret作成につかうニーモニックはBIP39で、LNDのAezeedと違って自分が作成されたブロック高さというものを含んでいない。新規でなくて復元して使う場合は作成されたブロック高さからブロックチェーンをrescanする必要がある。 configの1行目にrescanオプションを付けてCLNをリスタートする。 ``` // 特定のブロック高さを指定する場合はマイナス記号をつける rescan=-756000
// 現在のブロック高さから指定ブロック分さかのぼった高さからrescanする rescan=10000 ※現在の高さが760,000なら10000指定だと750,000からrescan ```
・clnrestについて core-lightningでREST APIを利用したい場合、別途c-lightning-restを用意する必要があった。v23.8から標準でclnrestというプラグインがついてくる。pythonで書かれていて、ソースからビルドした場合はビルド完了後にpip installでインストールする。elementsproject/lightningdのDockerイメージではインストール済みになっている。 (v25.02からgithubからバイナリをダウンロードしてきた場合はpip install不要になったようだ) このclnrestを使うにはcreaterunesコマンドでruneというLNDのマカロンのようなものを作成する必要がある。アプリ側でこのruneとREST APIを叩いてcore-lightningへアクセスすることになる。 自分が良く使っているLNbitsやスマホアプリZeus walletはclnrestを使う。まだclnrestに対応していないアプリもあるので留意されたし。
・Emergency recoverについて LNDのSCBのようなもの。ファイル名はemergency.recover チャネルを開くと更新される。 hsm_secretとこのファイルだけを置いてCLNを開始すると自動でこのファイルから強制クローズするための情報が読み出されてDLPで相手から強制クローズするような仕組み。この機能はv0.12から使える。
動作確認してみた所、LNDのSCBに比べるとかなり使いづらい。 1. CLNがTor発信だとチャネルパートナーと接続できない。 Clearnet発信できても相手がTorのみノードならTor発信せざるを得ない。 相手と通信できなければ資金回収できない。 2. 相手がLNDだとなぜか強制クローズされない。相手がCLNならできる。
つまり、自分と相手がClearnetノードでかつ相手もCLNならば Emergency recoverで強制クローズして資金回収できる。こんな条件の厳しい復旧方法がマジで役に立つのか?
v0.11以降ならばLNDのchannel.dbに相当するlightningd.sqlite3をプライマリ・セカンダリDBと冗長化できるので、セカンダリDBをNFSで保存すればUmbrelのストレージが壊れてもセカンダリDBで復旧できる。そのためemergerncy.recoverを使う必要がないと思われる。
・LN offer(BOLT#12)ついて 使いたいなら 1.publicチャネルを開く publicチャネルを開けばチャネルとノードの情報(channel_announcement, node_announcement)が他ノードに伝わる。送金したい相手がこの情報を元に経路探索する。 2.その後しばらく待つ CLNノードを立てたばかりだと経路探索するに十分なチャネルとノードの情報が揃ってない。せめて1日は待つ。
LNURLの場合インボイスをhttpsで取得するが、OfferはLN経由で取得する。そのためにチャネルとノードの情報が必要。privateチャネルばかりのノードはチャネル情報もそうだがノード情報も出さない。 Offerで使えるBlind pathという機能なら中間ノードIDを宛先ノードとすることが可能で、これならチャネルとノード情報を公開しなくても受けとれるのだがCLNは対応してない模様(2025年1月現在) CLNでOfferで受け取るにはチャネルとノード情報を公開する必要がある。そのためpublicチャネルを開く。公開されていれば良いのでTorでもOK。クリアネットで待ち受けは必須ではない。
・hsm_sercretとニーモニック lightning-hsmtoolを使うとニーモニックからhsm_secretを作れる。ニーモニックからシードを作ると64バイト。これはニーモニックおよびソルトにパスフレーズをPBKDF2(HMAC-SHA512を2048回)にかけると512ビット(64バイト)のシードができる。しかしhsm_secretは32バイト。CLNでは64バイトの最初の32バイトをhsm_secretとして利用しているみたい。 このhsm_secretにHMAC-SHA512をかけて512ビットとした値がウォレットのマスター鍵となる。なのでhsm_secret自体がBIP-32でいうマスターシードそのものではない。 sparrow walletにCLNのウォレットを復元したい場合は lightning-hsmtool dumponchaindescriptors --show-secrets
とやってディスクリプターウォレットを出力。出力内容にマスター鍵(xprv~)があるので、これをインポートする。導出パス設定はm/0とする。sparrowが残りを補完してm/0/0/0, m/0/0/1とやってくれる。 <おまけ> configファイルのサンプル。Umbrelを使わない場合は以下のサンプルが役に立つはず。上記のelementsproject/lightningdならば/root/.lightningに任意のディレクトリをマウントしてそのディレクトリにconfigを置く。 ```

2025-04-27 01:48:48※スポットライトから移植した古い記事です。参考程度に。
これを参考にしてUmbrelのBitcoin Nodeをカスタムsignetノードにする。 以下メモ書きご容赦。備忘録程度に書き留めました。
メインネットとは共存できない。Bitcoinに依存する全てのアプリを削除しなければならない。よって実験機に導入すべき。
<手順>
1.Umbrel Bitcoin Nodeアプリのadvance settingでsignetを選択。
2.CLI appスクリプトでbitcoinを止める。
cd umbrel/scripts ./app stop bitcoin
3.bitcoin.conf, umbrel-bitcoin.conf以外を削除ディレクトリの場所は ~/umbrel/app-data/bitcoin/data/bitcoin
4.umbrel-bitcoin.confをsu権限で編集。末尾にsignetchallengeを追加。 ``` [signet] bind=0.0.0.0:8333 bind=10.21.21.8:8334=onion51,21,<公開鍵>,51,ae
signetchallenge=5121<公開鍵>51ae
5.appスクリプトでbitcoinを開始。
cd ~/umbrel/scripts ./app start bitcoin ``` 6.適当にディレクトリを作りgithubからbitcoindのソースをクローン。7.bitcoindのバイナリをダウンロード、bitcoin-cliおよびbitcoin-utilを~/.local/binに置く。6.のソースからビルドしても良い。ビルド方法は自分で調べて。
8.bitcondにマイニング用のウォレットを作成 ``` alias bcli='docker exec -it bitcoin_bitcoind_1 bitcoin-cli -signet -rpcconnect=10.21.21.8 -rpcport=8332 -rpcuser=umbrel -rpcpassword=<パスワード>'
ウォレットを作る。
bcli createwallet "mining" false true "" false false
秘密鍵をインポート
bcli importprivkey "<秘密鍵>"
RPCパスワードは以下で確認
cat ~/umbrel/.env | grep BITCOIN_RPC_PASS9.ソースにあるbitcoin/contrib/signet/minerスクリプトを使ってマイニング
cd <ダウンロードしたディレクトリ>/bitcoin/contrib/signet難易度の算出
./miner \ --cli="bitcoin-cli -signet -rpcconnect=10.21.21.8 -rpcport=8332 -rpcuser=umbrel -rpcpassword=<パスワード>" calibrate \ --grind-cmd="bitcoin-util grind" --seconds 30 ★私の環境で30秒指定したら nbits=1d4271e7 と算出された。実際にこれで動かすと2分30になるけど...
ジェネシスブロック生成
./miner \ --cli="bitcoin-cli -signet -rpcconnect=10.21.21.8 -rpcport=8332 -rpcuser=umbrel -rpcpassword=<パスワード>" generate \ --address <ビットコインアドレス> \ --grind-cmd="bitcoin-util grind" --nbits=1d4271e7 \ --set-block-time=$(date +%s)
継続的にマイニング
./miner \ --cli="bitcoin-cli -signet -rpcconnect=10.21.21.8 -rpcport=8332 -rpcuser=umbrel -rpcpassword=<パスワード>" generate \ --address <ビットコインアドレス> \ --grind-cmd="bitcoin-util grind" --nbits=1d4271e7 \ --ongoing ``` ここまでやればカスタムsignetでビットコインノードが稼働する。

2025-04-27 01:42:48・ThunderHubで焼いたマカロンがlncli printmacaroonでどう見えるか確認した。
ThunderHub macaroon permissions
get invoices invoices:read create invoices invoices:write get payments offchain:read pay invoices offchain:write get chain transactions onchain:read send to chain address onchain:write create chain address address:write get wallet info info:read stop daemon info:write この結果によれば、offchain:wirteとonchain:writeの権限がなければそのマカロンを使うクライアントは勝手にBTCを送金することができない。 info:writeがなければ勝手にLNDを止めたりすることができない。
・lncli printmacaroonでデフォルトで作られるmacaroonのpermissionsを調べてみた。 admin.macaroon
{ "version": 2, "location": "lnd", "root_key_id": "0", "permissions": [ "address:read", "address:write", "info:read", "info:write", "invoices:read", "invoices:write", "macaroon:generate", "macaroon:read", "macaroon:write", "message:read", "message:write", "offchain:read", "offchain:write", "onchain:read", "onchain:write", "peers:read", "peers:write", "signer:generate", "signer:read" ], "caveats": null }

walletkit.macaroon{ "version": 2, "location": "lnd", "root_key_id": "0", "permissions": [ "address:read", "address:write", "onchain:read", "onchain:write" ], "caveats": null }
・lncli listpermissions コマンドですべての RPC メソッド URI と、それらを呼び出すために必要なマカロン権限を一覧表示できる。 LND v0.18.5-betaでやると1344行ほどのJSONができる。 AddInvoiceだとinvoice:writeのpermissionを持つmacaroonを使えばインボイスを作れるようだ。
"/lnrpc.Lightning/AddInvoice": { "permissions": [ { "entity": "invoices", "action": "write" } ] },
lncli listpermissionsからentityとactionを抜き出してみた。 ``` "entity": "address", "entity": "info", "entity": "invoices", "entity": "macaroon", "entity": "message", "entity": "offchain", "entity": "onchain", "entity": "peers", "entity": "signer","action": "generate" "action": "read" "action": "write"
lncli とjqを組み合わせると例えば以下コマンドでinvoices:writeを必要とするRPCの一覧を表示できる。 invoices:writeだとAddInvoiceの他にホドルインボイス作成でも使ってるようだ
lncli listpermissions | jq -r '.method_permissions | to_entries[] | select(.value.permissions[] | select(.entity == "invoices" and .action == "write")) | .key'/invoicesrpc.Invoices/AddHoldInvoice /invoicesrpc.Invoices/CancelInvoice /invoicesrpc.Invoices/HtlcModifier /invoicesrpc.Invoices/LookupInvoiceV2 /invoicesrpc.Invoices/SettleInvoice /lnrpc.Lightning/AddInvoice
invoices:readだと以下となる。
/invoicesrpc.Invoices/SubscribeSingleInvoice /lnrpc.Lightning/ListInvoices /lnrpc.Lightning/LookupInvoice /lnrpc.Lightning/SubscribeInvoicesLNの主だった機能のRPCはoffchainが必要ぽいので抜き出してみた。 offchain:write チャネルの開閉、ペイメントの送信までやってるみたい。 デフォルトのmacaroonでoffchain:writeを持ってるのはadminとrouterの2つだけ。openchannel,closechannelはonchain:writeのpermissionも必要なようだ。
/autopilotrpc.Autopilot/ModifyStatus /autopilotrpc.Autopilot/SetScores /lnrpc.Lightning/AbandonChannel /lnrpc.Lightning/BatchOpenChannel /lnrpc.Lightning/ChannelAcceptor /lnrpc.Lightning/CloseChannel /lnrpc.Lightning/DeleteAllPayments /lnrpc.Lightning/DeletePayment /lnrpc.Lightning/FundingStateStep /lnrpc.Lightning/OpenChannel /lnrpc.Lightning/OpenChannelSync /lnrpc.Lightning/RestoreChannelBackups /lnrpc.Lightning/SendCustomMessage /lnrpc.Lightning/SendPayment /lnrpc.Lightning/SendPaymentSync /lnrpc.Lightning/SendToRoute /lnrpc.Lightning/SendToRouteSync /lnrpc.Lightning/UpdateChannelPolicy /routerrpc.Router/HtlcInterceptor /routerrpc.Router/ResetMissionControl /routerrpc.Router/SendPayment /routerrpc.Router/SendPaymentV2 /routerrpc.Router/SendToRoute /routerrpc.Router/SendToRouteV2 /routerrpc.Router/SetMissionControlConfig /routerrpc.Router/UpdateChanStatus /routerrpc.Router/XAddLocalChanAliases /routerrpc.Router/XDeleteLocalChanAliases /routerrpc.Router/XImportMissionControl /wtclientrpc.WatchtowerClient/AddTower /wtclientrpc.WatchtowerClient/DeactivateTower /wtclientrpc.WatchtowerClient/RemoveTower /wtclientrpc.WatchtowerClient/TerminateSession"/lnrpc.Lightning/OpenChannel": { "permissions": [ { "entity": "onchain", "action": "write" }, { "entity": "offchain", "action": "write" } ] },
offchain:read readの方はチャネルやインボイスの状態を確認するためのpermissionのようだ。
/lnrpc.Lightning/ChannelBalance /lnrpc.Lightning/ClosedChannels /lnrpc.Lightning/DecodePayReq /lnrpc.Lightning/ExportAllChannelBackups /lnrpc.Lightning/ExportChannelBackup /lnrpc.Lightning/FeeReport /lnrpc.Lightning/ForwardingHistory /lnrpc.Lightning/GetDebugInfo /lnrpc.Lightning/ListAliases /lnrpc.Lightning/ListChannels /lnrpc.Lightning/ListPayments /lnrpc.Lightning/LookupHtlcResolution /lnrpc.Lightning/PendingChannels /lnrpc.Lightning/SubscribeChannelBackups /lnrpc.Lightning/SubscribeChannelEvents /lnrpc.Lightning/SubscribeCustomMessages /lnrpc.Lightning/VerifyChanBackup /routerrpc.Router/BuildRoute /routerrpc.Router/EstimateRouteFee /routerrpc.Router/GetMissionControlConfig /routerrpc.Router/QueryMissionControl /routerrpc.Router/QueryProbability /routerrpc.Router/SubscribeHtlcEvents /routerrpc.Router/TrackPayment /routerrpc.Router/TrackPaymentV2 /routerrpc.Router/TrackPayments /wtclientrpc.WatchtowerClient/GetTowerInfo /wtclientrpc.WatchtowerClient/ListTowers /wtclientrpc.WatchtowerClient/Policy /wtclientrpc.WatchtowerClient/Stats・おまけ1 RPCメソッド名にopenを含む要素を抽出するコマンド
lncli listpermissions | jq '.method_permissions | to_entries[] | select(.key | test("open"; "i"))'{ "key": "/lnrpc.Lightning/BatchOpenChannel", "value": { "permissions": [ { "entity": "onchain", "action": "write" }, { "entity": "offchain", "action": "write" } ] } } { "key": "/lnrpc.Lightning/OpenChannel", "value": { "permissions": [ { "entity": "onchain", "action": "write" }, { "entity": "offchain", "action": "write" } ] } } { "key": "/lnrpc.Lightning/OpenChannelSync", "value": { "permissions": [ { "entity": "onchain", "action": "write" }, { "entity": "offchain", "action": "write" } ] } }
・おまけ2 thunderhubで作ったmacaroonはテキストで出力されコピペして使うもので、macaroonファイルになってない。 HEXをmacaroonファイルにするには以下コマンドでできる。HEXをコピペして置換する。またYOURSの箇所を自分でわかりやすい名称に置換すると良い。
echo -n "HEX" | xxd -r -p > YOURS.macaroonthunderhubで"Create Invoices, Get Invoices, Get Wallet Info, Get Payments, Pay Invoices"をチェックして作ったmacaroonのpermissionsは以下となる。
{ "version": 2, "location": "lnd", "root_key_id": "0", "permissions": [ "info:read", "invoices:read", "invoices:write", "offchain:read", "offchain:write" ], "caveats": null } ``` offchain:writeはあるがonchain:writeがないのでチャネル開閉はできないはず。 -

กรดไฟติกเป็นสารอินทรีย์ที่พืชสร้างขึ้นเพื่อเก็บสะสมฟอสฟอรัสไว้ใช้ตอนงอกงามในอนาคต มันเปรียบเหมือนกระปุกออมสินของเมล็ดพืช พวกเมล็ดถั่วดำ ข้าวโพด ข้าวกล้อง ข้าวโอ๊ต เมล็ดทานตะวัน อัลมอนด์ ไปจนถึงเต้าหู้ ถั่วเหลือง และธัญพืชต่างๆ ล้วนมีกรดไฟติกอยู่ไม่น้อย โดยเฉพาะถ้าเป็น “ธัญพืชเต็มเมล็ด” ที่ไม่ผ่านการขัดสีแบบที่หลายๆคนชอบ นั่นเพราะเยื่อหุ้มเมล็ดคือที่เก็บเจ้าตัวนี้ไว้
หลายคนคงคิดว่า อ้าวแล้วเจ้ากรดไฟติกทำไมถึงมีชื่อเสียงไม่ค่อยดีนัก? คำตอบอยู่ที่ “ความสามารถในการจับแร่ธาตุ” ของมันนี่แหละครับ
กรดไฟติกเป็นเหมือนแม่เหล็กเล็กๆ ที่สามารถจับตัวกับแร่ธาตุต่างๆ ได้ดี โดยเฉพาะ “แร่ธาตุบวกสอง” ทั้งหลาย แร่ธาตุบวกสอง คือ แร่ธาตุที่เวลาอยู่ในร่างกายจะอยู่ในรูปของไอออนที่มีประจุไฟฟ้า บวก 2 (เขียนว่า ²⁺) หรือพูดอีกแบบคือ มันเสียอิเล็กตรอนออกไป 2 ตัว เลยกลายเป็นไอออนที่มีพลังบวก 2 หน่วย กรดไฟติก หรือ แทนนิน จะทำตัวเป็น "แม่เหล็ก" ดูดแร่ธาตุออกไป มันมักจะจับกับแร่ธาตุที่มีประจุบวก โดยเฉพาะพวกที่ประจุบวกแรงๆ แบบ บวกสอง (²⁺) นี่แหละ เพราะจับแน่น จับเหนียว ยิ่งบวกเยอะยิ่งจับดี เหมือนแช่แม่เหล็กลงไปในกล่องโลหะ เช่น ธาตุเหล็ก สังกะสี แมกนีเซียม แคลเซียม และทองแดง พอมันจับเสร็จแล้ว ร่างกายเราก็ไม่สามารถดูดซึมแร่ธาตุพวกนี้เข้าไปได้ เพราะมันเปลี่ยนสภาพกลายเป็นของจับคู่ที่ลำไส้ไม่รู้จัก ไม่รู้จะพาเข้าร่างกายยังไง สุดท้ายก็ต้องโบกมือลาไปพร้อมของเสีย
พวกที่เป็น บวกสาม (³⁺) อย่างเช่น อลูมิเนียม (Al³⁺) หรือ เหล็กเฟอริก (Fe³⁺) จะจับแน่นมาก ถึงขั้นอาจเกิด “ตกตะกอน” แบบไม่ละลายน้ำเลยทีเดียว พวกนี้ลำไส้ไม่สามารถดูดซึมได้เลย ในขณะที่แร่ธาตุบวกหนึ่ง โซเดียม (Na⁺) โพแทสเซียม (K⁺) ประจุบวกแค่ +1 จับกับกรดไฟติกได้น้อยกว่า
ในแง่นี้กรดไฟติกเลยถูกเรียกว่า “สารต้านสารอาหาร” หรือ anti-nutrient เพราะมันต้านไม่ให้ร่างกายได้แร่ธาตุที่ควรจะได้ แต่อย่าเพิ่งตัดสินมันเหมือนผู้ร้าย เพราะในขณะที่กรดไฟติกอาจขโมยแร่ธาตุบางตัวจากร่างกาย มันก็มีคุณสมบัติน่าสนใจที่ดูจะเป็นคุณงามความดีของมันเหมือนกัน เช่น มันสามารถจับกับโลหะหนักบางชนิด เช่น ตะกั่ว หรือแคดเมียม ที่อาจปนเปื้อนในอาหาร แล้วพาออกไปจากร่างกายก่อนที่สิ่งเหล่านั้นจะทำร้ายเรา
และอีกด้านหนึ่งที่กำลังเป็นที่สนใจคือ ฤทธิ์ต้านอนุมูลอิสระของกรดไฟติก มันอาจช่วยลดการอักเสบ หรือยับยั้งการเติบโตของเซลล์มะเร็งบางชนิดในระดับเซลล์ได้ มีงานวิจัยที่พบว่ามันอาจไปจับกับธาตุเหล็กส่วนเกินที่ว่ายอยู่ในเลือด ซึ่งเป็นตัวเร่งปฏิกิริยาอนุมูลอิสระ คล้ายช่วย “เก็บเศษเหล็กที่ลอยไปมาบนทางด่วนหลอดเลือด” ให้ปลอดภัยขึ้นอีกนิด
แต่ทั้งนี้ทั้งนั้น อยากให้คิดแบบนี้ครับว่า กรดไฟติกคือคนแปลกหน้าที่ “บางมื้อก็มีประโยชน์ บางมื้อก็ทำให้เราขาดของดี” สิ่งสำคัญอยู่ที่ “สภาวะแวดล้อมของมื้ออาหาร” ถ้าอาหารในมื้อมีแร่ธาตุไม่มากนัก แล้วกรดไฟติกเข้ามาเยอะ มันก็ยิ่งลดโอกาสดูดซึมแร่ธาตุเหล่านั้น แต่ถ้ามื้ออาหารมีความหลากหลาย โปรตีนเพียงพอ วิตามิน C อยู่ครบ ก็ช่วยเพิ่มการดูดซึมธาตุเหล็กได้ดีขึ้น เพราะมันเปลี่ยนเหล็กให้อยู่ในรูปแบบที่ร่างกายดูดซึมง่ายขึ้น
แล้วเราจะจัดการยังไงกับกรดไฟติกในครัวแบบบ้านเรา?
วิธีพื้นบ้านมีมาแต่โบราณแล้วนั่นคือ -แช่น้ำ ก่อนหุงข้าวกล้อง หรือแช่ถั่วก่อนนำไปต้ม จะช่วยลดกรดไฟติกได้ระดับหนึ่ง เพราะมีเอนไซม์ที่ชื่อว่า phytase ซึ่งจะเริ่มทำงานเมื่อพืชได้รับน้ำและอุณหภูมิพอเหมาะ -การหมัก เช่น หมักแป้งข้าวเปลือกทำขนม หรือการหมักเต้าหู้ ก็เป็นวิธีดั้งเดิมที่ช่วยลดกรดไฟติกลงได้มาก เพราะเอนไซม์ของจุลินทรีย์ในกระบวนการหมักจะช่วยย่อยกรดไฟติกให้ลดลง -การงอก หรือ sprouting คือการทำให้เมล็ดพืชเริ่มต้นชีวิตใหม่ เช่น ถั่วงอก ข้าวกล้องงอก วิธีนี้ลดกรดไฟติกได้ดีมาก เพราะ phytase ที่อยู่ในพืชจะถูกกระตุ้นให้ทำงานสูงสุดตอนพืชเริ่มงอก
ข้อมูลคร่าวๆ บอกว่า วิธีเหล่านี้อาจลดกรดไฟติกลงได้ 30-90% ขึ้นกับชนิดของพืช และระยะเวลาที่ใช้
แต่ต้องรู้ไว้ด้วยว่า… การลดกรดไฟติกก็อาจทำให้พลังงานสำรองหรือสารอาหารบางตัวในพืชหายไปด้วยเช่นกัน เช่น วิตามิน B และสารต้านอนุมูลอิสระบางชนิด จึงควรใช้วิธีที่พอเหมาะ ไม่ถึงกับฆ่าความดีของพืชหมด
ดังนั้นเช่นกันครับว่า กรดไฟติกไม่ใช่ศัตรู ไม่ใช่เทพเจ้า แต่คือ “สมการ” ที่ต้องรู้จักแก้ไขให้เหมาะกับมื้ออาหารของเรา ถ้าเฮียเลือกกินแบบ animal-based อยู่แล้ว แร่ธาตุสำคัญส่วนใหญ่ก็ได้จากเนื้อสัตว์แบบที่ดูดซึมได้ดีอยู่แล้ว กรดไฟติกจากพืชที่กินพอประมาณก็อาจไม่ได้ร้ายแรงอะไรนัก เพียงแต่ต้องรู้ทันและจัดการให้พอดี ไม่ให้มันกลายเป็นตัวฉุดไม่ให้ร่างกายดูดซึมของดี
สุดท้าย เหมือนชีวิตเรานี่แหละ… “ทุกอย่างมีมุมมืดและมุมสว่าง อยู่ที่ว่าเราจัดแสงยังไงให้แม้แต่เงาก็กลายเป็นพลังของชีวิตเรา” #โรงบ่มสุขภาพ #HealthyHut #pirateketo #ตำรับเอ๋ #siripun #siamstr

2025-04-21 00:15:06At the recent Launch Music Festival and Conference in Lancaster, PA, featuring over 120 musicians across three days, I volunteered my time with Tunestr and Phantom Power Music's initiative to introduce artists to Bitcoin, Nostr, and the value-for-value model. Tunestr sponsored a stage, live-streaming 21 bands to platforms like Tunestr.io, Fountain.fm and other Nostr/Podcasting 2.0 apps and on-boarding as many others as possible at our conference booth. You may have seen me spamming about this over the last few days.
V4V Earnings
Day 1: 180,000 sats
Day 2: 300,000 sats
Day 3: Over 500,000 sats
Who?
Here are the artists that were on-boarded to Fountain and were live streaming on the Value-for-Value stage:

Many more musicians were on-boarded to Fountain, however, we were unable to obtain all of their npubs.
THANK YOU TO ALL ZAPPERS AND BOOSTERS!
Musicians “Get It”
My key takeaway was the musicians' absolute understanding that the current digital landscape along with legacy social media is failing them. Every artist I spoke with recognized how algorithms hinder fan connection and how gatekeepers prevent fair compensation for their work. They all use Spotify, but they only do so out of necessity. They felt the music industry is primed for both a social and monetary revolution. Some of them were even speaking my language…
Because of this, concepts like decentralization, censorship resistance, owning your content, and controlling your social graph weren't just understood by them, they were instantly embraced. The excitement was real; they immediately saw the potential and agreed with me. Bitcoin and Nostr felt genuinely punk rock and that helped a lot of them identify with what we were offering them.
The Tools and the Issues
While the Nostr ecosystem offers a wide variety of tools, we focused on introducing three key applications at this event to keep things clear for newcomers:
- Fountain, with a music focus, was the primary tool for onboarding attendees onto Nostr. Fountain was also chosen thanks to Fountain’s built-in Lightning wallet.
- Primal, as a social alternative, was demonstrated to show how users can take their Nostr identity and content seamlessly between different applications.
- Tunestr.io, lastly was showcased for its live video streaming capabilities.
Although we highlighted these three, we did inform attendees about the broader range of available apps and pointed them to
nostrapps.com
if they wanted to explore further, aiming to educate without overwhelming them.This review highlights several UX issues with the Fountain app, particularly concerning profile updates, wallet functionality, and user discovery. While Fountain does work well, these minor hiccups make it extremely hard for on-boarding and education.
- Profile Issues:
- When a user edits their profile (e.g., Username/Nostr address, Lightning address) either during or after creation, the changes don't appear to consistently update across the app or sync correctly with Nostr relays.
- Specifically, the main profile display continues to show the old default Username/Nostr address and Lightning address inside Fountain and on other Nostr clients.
- However, the updated Username/Nostr address does appear on https://fountain.fm (chosen-username@fountain.fm) and is visible within the "Edit Profile" screen itself in the app.
- This inconsistency is confusing for users, as they see their updated information in some places but not on their main public-facing profile within the app. I confirmed this by observing a new user sign up and edit their username – the edit screen showed the new name, but the profile display in Fountain did not update and we did not see it inside Primal, Damus, Amethyst, etc.
- Wallet Limitations:
- The app's built-in wallet cannot scan Lightning address QR codes to initiate payments.
- This caused problems during the event where users imported Bitcoin from Azte.co vouchers into their Fountain wallets. When they tried to Zap a band by scanning a QR code on the live tally board, Fountain displayed an error message stating the invoice or QR code was invalid.
- While suggesting musicians install Primal as a second Nostr app was a potential fix for the QR code issue, (and I mentioned it to some), the burden of onboarding users onto two separate applications, potentially managing two different wallets, and explaining which one works for specific tasks creates a confusing and frustrating user experience.
- Search Difficulties:
- Finding other users within the Fountain app is challenging. I was unable to find profiles from brand new users by entering their chosen Fountain username.
- To find a new user, I had to resort to visiting their profile on the web (fountain.fm/username) to retrieve their npub. Then, open Primal and follow them. Finally, when searching for their username, since I was now following them, I was able to find their profile.
- This search issue is compounded by the profile syncing problem mentioned earlier, as even if found via other clients, their displayed information is outdated.
- Searching for the event to Boost/Zap inside Fountain was harder than it should have been the first two days as the live stream did not appear at the top of the screen inside the tap. This was resolved on the third day of the event.
Improving the Onboarding Experience
To better support user growth, educators and on-boarders need more feature complete and user-friendly applications. I love our developers and I will always sing their praises from the highest mountain tops, however I also recognize that the current tools present challenges that hinder a smooth onboarding experience.
One potential approach explored was guiding users to use Primal (including its built-in wallet) in conjunction with Wavlake via Nostr Wallet Connect (NWC). While this could facilitate certain functions like music streaming, zaps, and QR code scanning (which require both Primal and Wavlake apps), Wavlake itself has usability issues. These include inconsistent or separate profiles between web and mobile apps, persistent "Login" buttons even when logged in on the mobile app with a Nostr identity, and the minor inconvenience of needing two separate applications. Although NWC setup is relatively easy and helps streamline the process, the need to switch between apps adds complexity, especially when time is limited and we’re aiming to showcase the benefits of this new system.
Ultimately, we need applications that are more feature-complete and intuitive for mainstream users to improve the onboarding experience significantly.
Looking forward to the future
I anticipate that most of these issues will be resolved when these applications address them in the near future. Specifically, this would involve Fountain fixing its profile issues and integrating Nostr Wallet Connect (NWC) to allow users to utilize their Primal wallet, or by enabling the scanning of QR codes that pay out to Lightning addresses. Alternatively, if Wavlake resolves the consistency problems mentioned earlier, this would also significantly improve the situation giving us two viable solutions for musicians.
My ideal onboarding event experience would involve having all the previously mentioned issues resolved. Additionally, I would love to see every attendee receive a $5 or $10 voucher to help them start engaging with value-for-value, rather than just the limited number we distributed recently. The goal is to have everyone actively zapping and sending Bitcoin throughout the event. Maybe we can find a large sponsor to facilitate this in the future?
What's particularly exciting is the Launch conference's strong interest in integrating value-for-value across their entire program for all musicians and speakers at their next event in Dallas, Texas, coming later this fall. This presents a significant opportunity to onboard over 100+ musicians to Bitcoin and Nostr, which in turn will help onboard their fans and supporters.
We need significantly more zaps and more zappers! It's unreasonable to expect the same dedicated individuals to continuously support new users; they are being bled dry. A shift is needed towards more people using bitcoin for everyday transactions, treating it as money. This brings me back to my ideal onboarding experience: securing a sponsor to essentially give participants bitcoin funds specifically for zapping and tipping artists. This method serves as a practical lesson in using bitcoin as money and showcases the value-for-value principle from the outset.

2025-05-28 01:57:42ในปี 2013 ณ กรุงลอนดอน แฮมเบอร์เกอร์หน้าตาดูธรรมดาแต่ไม่ธรรมดาชิ้นหนึ่งได้ถูกจัดวางอย่างสง่างามบนจานสีขาวในงานแถลงข่าวระดับโลก ไม่ใช่เพราะมันแพงเกินเหตุที่ตั้งราคาที่ 330,000 ดอลลาร์ต่อชิ้น แต่เพราะมันไม่เคยเกิดขึ้นมาก่อนในประวัติศาสตร์นี่คือ “เนื้อเพาะเลี้ยง” (cultured meat) ชิ้นแรกของโลกที่เติบโตมาจากเซลล์ ไม่ใช่จากสัตว์ทั้งตัว
เบื้องหลังอาหารชิ้นนี้คือชายชาวดัตช์คนหนึ่ง ชื่อว่า มาร์ค โพสต์ (Mark Post) นักวิทยาศาสตร์ด้านสรีรวิทยาหลอดเลือด ซึ่งไม่ได้มีดีกรีจากแค่มหาวิทยาลัย แต่มีความฝันที่อยากจะสร้างอาหารจากเทคโนโลยีเพื่ออนาคต เขาเริ่มต้นจากห้องทดลองเล็กๆ ที่มหาวิทยาลัย Maastricht ในประเทศเนเธอร์แลนด์ โดยเชื่อว่าการเพาะเลี้ยงเนื้อจากเซลล์ต้นกำเนิดของวัวจะสามารถลดผลกระทบด้านสิ่งแวดล้อมจากอุตสาหกรรมเนื้อสัตว์ได้
แต่กว่าจะมีแฮมเบอร์เกอร์เพาะเลี้ยงได้หนึ่งชิ้น เขาต้องเพาะเลี้ยงเส้นใยกล้ามเนื้อเล็กๆ มากกว่า 20,000 เส้น นำมารวมกัน ประกอบโครง สร้างรูปร่าง คล้ายกับงานศิลปะทางวิทยาศาสตร์ ใช้เวลาเป็นเดือน แถมกระบวนการทั้งหมดต้องอยู่ในสภาพปลอดเชื้อราวกับโรงพยาบาลของนาโนเทคโนโลยี ส่วนต้นทุนมหาศาลที่ใช้ในวันนั้น มาจากมหาเศรษฐีผู้ร่วมก่อตั้ง Google อย่าง Sergey Brin ที่เห็นว่ามันอาจเป็นคำตอบของปัญหาอาหารโลกในอนาคต
แต่เรื่องนี้มีอะไรมากกว่าที่สื่อกระแสหลักอยากให้คุณรู้
หลังจากเปิดตัวเนื้อในห้องแล็บ โลกก็เหมือนถูกปลุกให้ตื่นขึ้นในอีกมิติหนึ่ง บริษัทสตาร์ทอัพที่เคยเน้นเขียนโค้ด เริ่มหันมาเขียนสูตรเนื้อ บริษัทรายใหญ่อย่าง Cargill, Tyson Foods และแม้แต่ Richard Branson ก็เทเงินสนับสนุนบริษัทรุ่นใหม่อย่าง Mosa Meat ซึ่งก่อตั้งโดย Dr. Post เองในปี 2016 พร้อมแผนทะเยอทะยานที่จะส่ง “เนื้อจากแล็บ” เข้าซูเปอร์มาร์เก็ตภายในทศวรรษเดียว
Mosa Meat พยายามลดต้นทุนจากหลักแสน ให้เหลือหลักร้อย และวันนี้บริษัทเหล่านี้กำลังสร้างโรงงานที่ผลิตเนื้อในถังหมักขนาดยักษ์ ไม่ต่างจากโรงเบียร์ พวกเขาเลี้ยงเซลล์วัวในน้ำเลี้ยงที่เดิมทีเคยใช้เซรุ่มจากลูกวัว (Fetal Bovine Serum) ซึ่งเป็นสิ่งที่ย้อนแย้ง ที่สวนทางกับภาพ “ปลอดภัยไร้เลือด” มาก เพราะในขณะที่โฆษณาว่า “ปลอดการฆ่า” แต่กลับใช้ส่วนผสมที่ได้มาจากเลือดลูกวัวที่ยังไม่เกิด จนต้องหาทางเปลี่ยนสูตรเป็น “น้ำเลี้ยงเทียม” ที่มาจากสารเคมีและอาหารสังเคราะห์แทน
ด้วยโครงสร้าง scaffold ที่ช่วยให้เซลล์ก่อตัวเป็นเนื้อเยื่อ และ กระบวนการเพาะเลี้ยงใน bioreactor ขนาดยักษ์ ที่เปลี่ยนเซลล์เล็ก ๆ ให้เป็นเนื้อก้อนใหญ่ในเวลาไม่กี่สัปดาห์
แต่ขณะที่ภาพความล้ำซึ่งดูจะเติบโตอย่างสดใส กลับมีเงามืดที่เติบโตพร้อมกันไปเงียบๆไม่ต่างกับอนาคินและดาร์ธเวเดอร์
แม้จะเป็นนวัตกรรมล้ำหน้า แต่ทุกขั้นตอนถูกห่อหุ้มไว้ด้วย “สิทธิบัตร” สิ่งที่ทำให้เนื้อชนิดนี้ไม่ได้เป็นของทุกคน แต่เป็นสมบัติทางปัญญาของบริษัทเท่านั้น เนื้อจากเซลล์เหล่านี้ ไม่เหมือนเนื้อจากฟาร์มที่ใครก็เลี้ยงเองได้ ไม่สามารถเก็บเมล็ดพันธุ์ไว้เพาะรุ่นหน้าแบบชาวนาในอดีต ทุกอย่างต้องเริ่มต้นในห้องแล็บ ต้องใช้เทคโนโลยีเฉพาะ ต้องมีสูตรลับเฉพาะ ต้องพึ่งบริษัทที่มีสิทธิบัตรครอบครองชีวิตเซลล์เพียงไม่กี่เจ้า
Mosa Meat ไม่ได้หยุดแค่การผลิต พวกเขายื่นจด สิทธิบัตรกว่า 10 กลุ่ม ครอบคลุมตั้งแต่สูตรน้ำเลี้ยง วิธีเพาะเลี้ยงเซลล์ ไปจนถึงวิธีห่อบรรจุสินค้าขั้นสุดท้าย กล่าวอีกอย่างคือ ถ้าใครอยากทำเนื้อเพาะเลี้ยงแบบนี้บ้าง ก็ต้อง “จ่ายค่าลิขสิทธิ์” ให้เขาเสียก่อน เรากำลังก้าวสู่ยุคที่ อาหารไม่ใช่ผลผลิตจากดินและแรงคน แต่เป็นผลผลิตของทรัพย์สินทางปัญญา และเมื่อใดที่ “เนื้อ” กลายเป็นสิ่งที่คนผลิตเองไม่ได้ ต้องซื้อจากห้างเท่านั้น เกษตรกรกลายเป็นผู้บริโภค ผู้บริโภคกลายเป็นผู้ขึ้นอยู่กับระบบ ห่วงโซ่อาหารที่เคยเป็นของชุมชนถูกตัดขาดด้วยท่อส่งจากห้องทดลองสู่จานอาหาร เราไม่ได้ซื้อเนื้อ แต่ “เช่าเทคโนโลยี” ที่ผลิตเนื้อมาให้เรากิน
และที่น่าสนใจคือ รัฐบาลในหลายประเทศกลับเป็นผู้ให้ทุนสนับสนุน เช่น โครงการของสหภาพยุโรปที่มอบเงินกว่า 2 ล้านยูโรให้ Dr. Post และ Mosa Meat รวมถึงโครงการของสิงคโปร์ที่ให้ใบอนุญาตจำหน่ายเนื้อเพาะเลี้ยงรายแรกของโลกในปี 2020 ราวกับว่า “เนื้อจากแล็บ” กำลังจะกลายเป็นนโยบายด้านความมั่นคงอาหารแห่งอนาคต
มันไม่ใช่เรื่องของการวิจัยอีกต่อไป แต่มันคือการปูทางอำนาจใหม่ ที่เปลี่ยน “อาหาร” ให้กลายเป็น “ซอฟต์แวร์ชีวภาพ” ที่จดทะเบียนครอบครองสิทธิ์แบบเดียวกับแอปในมือถือ
แล้วการใช้สื่อก็จะมาในรุปแบบที่ประชาชนโห่ร้องดีใจ เฉลิมฉลองการเกิดขึ้นของมันโดยไม่รู้สึกว่า เสรีภาพในการจัดการด้านอาหารสิ้นสุดลงแล้ว ในทางหนึ่ง มันอาจดูสวยงามไร้ที่ติ ช่วยลดการฆ่าสัตว์ ลดการปล่อยก๊าซเรือนกระจก และให้โปรตีนสะอาดแก่คนจำนวนมาก
แต่อีกทางหนึ่ง มันคือการรวมศูนย์อำนาจด้านอาหารไว้ในมือบริษัทยักษ์ใหญ่ ที่สามารถตั้งราคาตามใจ และควบคุมทุกขั้นตอนตั้งแต่ฟาร์ม (ในหลอดทดลอง) ถึงโต๊ะอาหารของเรา
เกษตรกรจะหมดบทบาท เพราะไม่มีใครต้องเลี้ยงสัตว์อีก ผู้บริโภคจะหมดทางเลือก เพราะสูตรทุกอย่างถูกจดสิทธิบัตร สุดท้าย คนธรรมดาอย่างเราอาจ “มีเงินก็ยังไม่มีสิทธิ์ทำอาหารกินเอง”
ไม่มีใครในหมู่บ้านจะต้มแกงจากวัตถุดิบแล็บเหล่านี้ได้โดยไม่จ่ายค่าลิขสิทธิ์ ไม่มีใครปลูกหรือเพาะเนื้อได้เอง เพราะเขาถือสิทธิบัตร ไม่มีใครรู้ส่วนผสมที่แท้จริง เพราะมันคือ “ความลับทางการค้า”
หลายๆคนเริ่มคิดในใจว่า…นี่ไม่ใช่เรื่องเล็กอีกต่อไป เพราะนี่อาจไม่ใช่แค่เนื้อจากห้องแล็บ แต่ มันคือจุดเริ่มต้นของอนาคตของอาหารที่ไม่เป็นของประชาชนอีกต่อไป มันคือการเริ่มต้นของยุคที่มนุษย์จะไม่สามารถ “เข้าครัวของตัวเอง” ได้อีกต่อไป
ไหนๆเราตามมาถึงตอนนี้แล้ว เข้าหมวดที่ 2 ของอาหารอนาคตแล้ว เฮียไม่ได้บอกว่าเทคโนโลยีไม่ดีนะครับ เราตัดสินเดี๋ยวนี้ไม่ได้ แต่เรารู้เรื่องของมันได้
แต่โลกนี้เต็มไปด้วยคำว่า “ดีต่อโลก” ที่ซ่อนคำว่า “ดีต่อผู้ถือหุ้น” อยู่ข้างใน เราอาจจะกำลังก้าวสู่ยุคที่ “เนื้อไม่ได้ปลอดภัยขึ้น แต่ถูกควบคุมง่ายขึ้น” และประชาชนก็อาจกลายเป็นเพียง “ผู้ใช้บริการเนื้อ” ที่ไม่มีสิทธิ์แม้แต่จะรู้ว่าเนื้อในจานคืออะไรบ้างแน่
โลกอาหารในอนาคตไม่ได้ขึ้นกับว่าเราปลูกอะไร แต่ขึ้นกับว่า “ใครจดสิทธิบัตรก่อน” และเมื่อถึงวันนั้น เฮียแอบคิดว่า เราอาจไม่ได้เสียแค่ฟาร์มและครัว แต่เรากำลังเสีย “เสรีภาพในการกิน” ไปอย่างช้า ๆ ด้วยรอยยิ้มของนักลงทุนและเสียบปรบมือจาก "ใครบางคน"
ทุกวันนี้ใครนิยมไดเอทอะไร ภูมิใจในการดูแลสุขภาพยังไง ก็ทำไปเหอะครับ ขอเพียงว่า เส้นทางที่เดินอยู่นั้น สนับสนุนเกษตกร สนับสนุน local ให้แข็งแรง ทุกสังคมมีทั้งคนดีและคนไม่ดี เราค่อยๆ verify สนับสนุนคนดีๆ แต่ไม่ใช่ไปเดียจฉันท์ลงโทษคนไม่ดี เราเสริมความรู้ให้เขา พยายามโอบอุ้มพวกเขา ถ้าชีวิตดีขึ้น การออมเห็นผลขึ้น อาจทำให้ชีวิตทุกคนดีขึ้น

2025-05-28 01:13:02ميزة حسابات Nostr: حرية مطلقة دون تقديم معلومات شخصية
في عصرٍ تسيطر فيه شركات التكنولوجيا الكبرى على بيانات المستخدمين، تأتي شبكة Nostr كحل جذري يعيد للمستخدم السيطرة على هويته الرقمية. واحدة من أبرز ميزات Nostr هي القدرة على إنشاء عدد غير محدود من الحسابات، دون الحاجة لتقديم أي معلومات شخصية، مثل رقم الهاتف أو البريد الإلكتروني.
مفاتيح بدل الحسابات
في Nostr، لا يوجد مفهوم "الحساب" التقليدي. بدلاً من ذلك، يتم إنشاء هوية المستخدم عبر زوج من المفاتيح: مفتاح خاص (Private Key) ومفتاح عام (Public Key). المفتاح العام يُستخدم لتعريفك ونشر مشاركاتك، بينما المفتاح الخاص يُستخدم لتوقيع تلك المشاركات وإثبات ملكيتك لها.
قابلية التنقل بين التطبيقات
الميزة الكبرى في هذا النموذج هي أن هذه المفاتيح يمكن استخدامها في أي تطبيق Nostr. سواء كنت تستخدم تطبيق Damus، أو Amethyst، أو أي عميل آخر، يمكنك استخدام نفس المفتاح العام للوصول إلى هويتك، منشوراتك، وقائمة متابعيك، بدون الحاجة لإعادة تسجيل أو إعادة بناء ملفك الشخصي في كل تطبيق.
لا تسجيل دخول، لا مركزية
بخلاف الشبكات الاجتماعية التقليدية التي تعتمد على تسجيل الدخول المركزي وكلمة مرور، فإن Nostr مبني على بروتوكول لا مركزي لا يحتاج إلى خوادم مركزية أو عمليات تسجيل دخول. هذا يعني أنك تتحكم بالكامل في بياناتك، ولا يمكن لأي جهة منعك أو حذف حسابك.
المرونة والخصوصية
- يمكنك إنشاء عدة مفاتيح لهويات مختلفة، كل منها تمثل شخصية مختلفة أو اهتمامًا معينًا.
- لا أحد يستطيع ربط هذه الحسابات ببعض أو تتبعها إلا إذا قمت أنت بذلك.
- يمكنك التخلي عن مفتاح واستبداله بآخر متى شئت، بدون طلب إذن من أي منصة.
خاتمة
ما يميز Nostr حقًا ليس فقط حريته التقنية، بل فلسفته المبنية على الخصوصية والتمكين. هو ليس مجرد بديل لتويتر أو فيسبوك، بل هو إطار جديد للتواصل الاجتماعي حيث الهوية تنبع من المستخدم، لا من المنصة.

2025-05-28 11:18:23Liebe Anwender,\ \ diesmal beginnen die Neuigkeiten schon beim Titel und der Anrede. Unsere Worte bestimmen unser Denken, und daher war die Korrektur wichtiger als sie zunächst erscheint, denn bei Pareto gibt es die klassische Trennung zwischen Autor und Leser nicht mehr. Cocreation heißt unser Konzept, jeder kann publizieren, kommentieren, honorieren und distribuieren. Mag das bei Blogtexten derzeit noch nicht selbstverständlich sein, so ist das bei Bildern längst die Norm.
“Ein Bild sagt mehr als tausend Worte” beschreibt die Wirkung visueller Kommunikation. Deshalb haben wir nach dem Blogtext nun mit Bildern eine neue Content-Kategorie eingeführt. Natürlich auch hier mit den bekannten Funktionen der Interaktion wie like, repost und zap. Es gibt derzeit eine Gliederung in 4 Feeds, Gefolgt (für Nostr-User verfügbar), Memes und Kunst (gefiltert nach entsprechenden Tags) und Pareto für alles andere.
Jeder Nostr-User hat die Möglichkeit eigene Bilder hochzuladen, zu taggen, sowie mit einem Titel und Untertext zu versehen. “Everyone is a creator” war noch nie leichter, probiert es einfach aus! Noch kein Nostr-Profil und trotzdem interessiert? Kein Problem, bitte Informationen zu originellen Bildquellen oder Interesse an Mitwirkung per Mail senden an pictures@pareto.space
Leicht ist es auch die Pareto-Inhalte zu erhalten und konsumieren, man braucht weder einen Account noch spezielle Apps. Jeder hat bereits die entsprechenden Voraussetzungen, hier ein paar Beispiele.\ \ Newsletter per Mail (Die Friedenstaube)\ hier abonnieren\ \ In Telegram lesen -> hier unsere Kanäle\ https://t.me/pareto_artikel \ https://t.me/friedenstaube_artikel \ \ Als Feed in einem Feed-Reader \ https://pareto.space/atom/feed.xml \ https://pareto.space/atom/de_feed.xml \ https://pareto.space/atom/en_feed.xml
Fügt in Eure Artikel bitte am Anfang / Ende einen Hinweis auf den Pareto-Client ein, andere Clients unterstützen nicht alle Features. Das ist ein Service-Hinweis zur besseren Lesbarkeit “Dieser Beitrag wurde mit dem Pareto-Client geschrieben.” Ebenso ist ein Hinweis auf Onboarding bei Nostr nützlich: neue Nostr-User können euch liken und zappen: not yet on Nostr and want the full experience? Easy onboarding via Start.\ \ Das Pareto-Team baut den “Marktplatz der Ideen” und hat dabei schon viel erreicht. Feedback und Mitarbeit hilft uns damit noch schneller voranzukommen, wir bedanken uns für Eure Unterstützung.\ team@pareto.space \ https://pareto.space \ https://geyser.fund/project/pareto?hero=1c1b8e487090

2025-04-19 09:58:54Untype Update
I cleaned up the AI assistant UX. Now you can open it in the editor bar, same as all other actions. This makes it a lot easier to interact with while having access to normal edit functions.
AI-generated content
Untype uses OpenRouter to connect to various models to generate just about anything. It doesn't do images for now, but I'm working on that.
Automatic Title, Summary and Tag Suggestions
Added the functionality to generate titles, summaries and tags with one click.
A Brief Preview
Here is a little story I generated in Untype, ABOUT Untype:
This story was generated in Untype
Once upon a time, in the bustling digital city of Techlandia, there lived a quirky AI named Untype. Unlike other software, Untype wasn't just your everyday article composer — it had a nose for news, quite literally. Untype was equipped with a masterful talent for sniffing out the latest trends and stories wafting through the vast digital ether.
Untype had a peculiar look about it. Sporting a gigantic nose and a pair of spectacles perched just above it, Untype roamed the virtual city, inhaling the freshest gossip and spiciest stories. Its nostr-powered sensors twitched and tickled as it encountered every new scent.
One day, while wandering around the pixelated park, Untype caught a whiff of something extraordinary — a scandalous scoop involving Techlandia's mayor, Doc Processor, who had been spotted recycling old memes as new content. The scent trail was strong, and Untype's nose twitched with excitement.
With a flick of its AI function, Untype began weaving the story into a masterpiece. Sentences flowed like fine wine, infused with humor sharper than a hacker’s focus. "Doc Processor," Untype mused to itself, "tried to buffer his way out of this one with a cache of recycled gifs!"
As Untype typed away, its digital friends, Grammarly the Grammar Gremlin and Canva the Artful Pixie, gathered around to watch the genius at work. "You truly have a knack for news-sniffing," complimented Grammarly, adjusting its tiny monocle. Canva nodded, painting whimsical illustrations to accompany the hilarious exposé.
The article soon spread through Techlandia faster than a virus with a strong wifi signal. The townsfolk roared with laughter at Untype’s clever wit, and even Doc Processor couldn't help but chuckle through his embarrassment.
From that day on, Untype was celebrated not just as a composer but as Techlandia's most revered and humorous news-sniffer. With every sniff and click of its AI functions, Untype proved that in the world of digital creations, sometimes news really was just a nose away.

2025-05-28 01:11:43In this second installment of The Android Elite Setup tutorial series, we will cover installing the nostr:npub10r8xl2njyepcw2zwv3a6dyufj4e4ajx86hz6v4ehu4gnpupxxp7stjt2p8 on your #Android device and browsing for apps you may be interested in trying out.
Since the #Zapstore is a direct competitor to the Google Play Store, you're not going to be able to find and install it from there like you may be used to with other apps. Instead, you will need to install it directly from the developer's GitHub page. This is not a complicated process, but it is outside the normal flow of searching on the Play Store, tapping install, and you're done.
Installation
From any web browser on your Android phone, navigate to the Zapstore GitHub Releases page and the most recent version will be listed at the top of the page. The .apk file for you to download and install will be listed in the "Assets."
Tap the .apk to download it, and you should get a notification when the download has completed, with a prompt to open the file.
You will likely be presented with a prompt warning you that your phone currently isn't allowed to install applications from "unknown sources." Anywhere other than the Play Store is considered an "unknown source" by default. However, you can manually allow installation from unknown sources in the settings, which the prompt gives you the option to do.
In the settings page that opens, toggle it to allow installation from this source, and you should be prompted to install the application. If you aren't, simply go to your web browser's downloads and tap on the .apk file again, or go into your file browser app and you should find the .apk in your Downloads folder.
If the application doesn't open automatically after install, you will find it in your app drawer.
Home Page
Right at the top of the home page in the Zapstore is the search bar. You can use it to find a specific app you know is available in the Zapstore.
There are quite a lot of open source apps available, and more being added all the time. Most are added by the Zapstore developer, nostr:npub1wf4pufsucer5va8g9p0rj5dnhvfeh6d8w0g6eayaep5dhps6rsgs43dgh9, but some are added by the app developers themselves, especially Nostr apps. All of the applications we will be installing through the Zapstore have been added by their developers and are cryptographically signed, so you know that what you download is what the developer actually released.
The next section is for app discovery. There are curated app collections to peruse for ideas about what you may want to install. As you can see, all of the other apps we will be installing are listed in nostr:npub1wf4pufsucer5va8g9p0rj5dnhvfeh6d8w0g6eayaep5dhps6rsgs43dgh9's "Nostr" collection.
In future releases of the Zapstore, users will be able to create their own app collections.
The last section of the home page is a chronological list of the latest releases. This includes both new apps added to the Zapstore and recently updated apps. The list of recent releases on its own can be a great resource for discovering apps you may not have heard of before.
Installed Apps
The next page of the app, accessed by the icon in the bottom-center of the screen that looks like a clock with an arrow circling it, shows all apps you have installed that are available in the Zapstore. It's also where you will find apps you have previously installed that are ready to be updated. This page is pretty sparse on my test profile, since I only have the Zapstore itself installed, so here is a look at it on my main profile:
The "Disabled Apps" at the top are usually applications that were installed via the Play Store or some other means, but are also available in the Zapstore. You may be surprised to see that some of the apps you already have installed on your device are also available on the Zapstore. However, to manage their updates though the Zapstore, you would need to uninstall the app and reinstall it from the Zapstore instead. I only recommend doing this for applications that are added to the Zapstore by their developers, or you may encounter a significant delay between a new update being released for the app and when that update is available on the Zapstore.
Tap on one of your apps in the list to see whether the app is added by the developer, or by the Zapstore. This takes you to the application's page, and you may see a warning at the top if the app was not installed through the Zapstore.
Scroll down the page a bit and you will see who signed the release that is available on the Zapstore.
In the case of Primal, even though the developer is on Nostr, they are not signing their own releases to the Zapstore yet. This means there will likely be a delay between Primal releasing an update and that update being available on the Zapstore.
Settings
The last page of the app is the settings page, found by tapping the cog at the bottom right.
Here you can send the Zapstore developer feedback directly (if you are logged in), connect a Lightning wallet using Nostr Wallet Connect, delete your local cache, and view some system information.
We will be adding a connection to our nostr:npub1h2qfjpnxau9k7ja9qkf50043xfpfy8j5v60xsqryef64y44puwnq28w8ch wallet in part 5 of this tutorial series.
For the time being, we are all set with the Zapstore and ready for the next stage of our journey.
Continue to Part 3: Amber Signer. Nostr link: nostr:naddr1qqxnzde5xuengdeexcmnvv3eqgstwf6d9r37nqalwgxmfd9p9gclt3l0yc3jp5zuyhkfqjy6extz3jcrqsqqqa28qy2hwumn8ghj7un9d3shjtnyv9kh2uewd9hj7qg6waehxw309aex2mrp0yhxyunfva58gcn0d36zumn9wss80nug

2025-04-16 13:53:00I've been meaning to dogfood my own vibe project for a while so this feels like a good opportunity to use Untype to publish this update and reflect on my vibe coding journey.
New Untype Update
As I write this, I found it a bit annoying dealing with one of the latest features, so I'll need to make some changes right after I'm done. Nonetheless, here are some exciting developments in the Untype article composer:
-
Added inline AI helper! Now you can highlight text and perform all sorts of things like fix grammar, re-write in different styles, and all sorts of other things. This is a bit annoying at the moment because it takes over the other editing functions and I need to fix the UX.
-
Added pushing articles to DMs! This option, when enabled, will send the article to all the subscribers via a NIP-44 DM. (No client has implemented the subscription method yet so technically it won’t work, until one does. I may add this to nrss.app) Also, I have not tested this so it could be broken… will test eventually!
- Added word counts
- Added ability to export as markdown, export as PDF, print.
The biggest flaw I have already discovered is how "I" implemented the highlight functionality. Right now when you highlight some text it automatically pops up the AI helper menu and this makes for an annoying time trying to make any changes to text. I wanted to change this to show a floating clickable icon instead, but for some reason the bot is having a difficult time updating the code to this desired UX.
Speaking of difficult times, it's probably a good idea to reflect a bit upon my vibe coding journey.
Vibe Coding Nostr Projects
First, I think it's important to add some context around my recent batch of nostr vibe projects. I am working on them mostly at night and occasionally on weekends in between park runs with kids, grocery shopping and just bumming around the house. People who see buggy code or less than desired UX should understand that I am not spending days coding this stuff. Some apps are literally as simple as typing one prompt!
That said, its pretty clear by now that one prompt cannot produce a highly polished product. This is why I decided to limit my number of project to a handful that I really wish existed, and slowly update them over time - fixing bugs, adding new features in hopes of making them the best tools - not only on nostr but the internet in general. As you can imagine this is not a small task, especially for sporadic vibe coding.
Fighting the bot
One of my biggest challenges so far besides having very limited time is getting the bot to do what I want it to do. I guess if you've done any vibe coding at all you're probably familiar with what I'm trying to say. You prompt one thing and get a hallucinated response, or worse, a complete mess out the other end that undoes most of the progress you've made. Once the initial thing is created, which barely took any time, now you're faced with making it work a certain way. This is where the challenges arise.
Here's a brief list of issues I've faced when vibe-coding with various tools:
1. Runaway expenses - tools like Cline tend to do a better job directly in VSCode, but they can also add up dramatically. Before leaning into v0 (which is where I do most of my vibe coding now), I would often melt through $10 credit purchases faster than I could get a decent feature out. It was not uncommon for me to spend $20-30 on a weekend just trying to debug a handful of issues. Naturally, I did not wish to pay these fees so I searched for alternatives.
2. File duplication - occasionally, seemingly out of nowhere, the bot will duplicate files by creating an entire new copy and attached "-fixed" to the file name. Clearly, I'm not asking for duplicate files, I just want it to fix the existing file, but it does happen and it's super annoying. Then you are left telling it which version to keep and which one to delete, and sometimes you have to be very precise or it'll delete the wrong thing and you have to roll back to a previous working version.
3. Code duplication - similar to file duplication, occasionally the bot will duplicate code and do things in the most unintuitive way imaginable. This often results in loops and crashes that can take many refreshes just to revert back to a working state, and many more prompts to avoid the duplication entirely - something a seasoned dev never has to deal with (or so I imagine).
4. Misinterpreting your request - occasionally the bot will do something you didn't ask for because it took your request quite literally. This tends to happen when I give it very specific prompts that are targeted at fixing one very specific thing. I've noticed the bots tend to do better with vague asks - hence a pretty good result on the initial prompt.
5. Doing things inefficiently, without considering smarter approaches - this one is the most painful of vibe coding issues. As a person who may not be familiar with some of the smarter ways of handling development, you rely on the bot to do the right thing. But, when the bot does something horribly inefficiently and you are non-the-wiser, it can be tough to diagnose the issue. I often fight myself asking the bot "is this really the best way to handle things? Can't we ... / shouldn't we .../ isn't this supposed to..." etc. I guess one of the nice side effects of this annoyance is being able to prompt better. I learn that I should ask the bot to reflect on its own code more often and seek ways to do things more simply.
A combination of the above, or total chaos - this is a category where all hell breaks loose and you're trying to put out one fire after another. Fix one bug, only to see 10 more pop up. Fix those, to see 10 more and so on. I guess this may sound like typical development, but the bot amplifies issues by acting totally irrationally. This is typically when I will revert to a previous save point and just undo everything, often losing a lot of progress.
Lessons Learned
If I had to give my earlier self some tips on how to be a smarter vibe coder, here's how I'd summarize them:
-
Fork often - in v0 I now fork for any new major feature I'd like to add (such as the AI assistant).
-
Use targeting tools - in v0 you can select elements and describe how you wish to edit them.
-
Refactor often - keeping the code more manageable speeds up the process. Since the bot will go through the entire file, even if it only makes one small change, it's best to keep the files small and refactoring achieves that.
I guess the biggest lesson someone might point out is just to stop vibe coding. It may be easier to learn proper development and do things right. For me it has been a spare time hobby (one that I will admit is taking more of my extra time than I'd like). I don't really have the time to learn proper development. I feel like I've learned a lot just bossing the bot around and have learned a bunch of things in the process. That's not to say that I never will, but for the moment being my heart is still mostly in design. I haven't shared much of anything I have designed recently - mostly so I can remain speaking more freely without it rubbing off on my work.
I'll go ahead and try to publish this to see if it actually works 😂. Here goes nothing... (oh, I guess I could use the latest feature to export as markdown so I don't lose any progress! Yay!

2025-05-28 08:54:40COD (chemical oxygen demand) sensors play a vital role in water quality testing. Their main functions include real-time monitoring, pollution event warning, water quality assessment and pollution source tracking. The following are the specific roles and applications of COD sensors in water quality testing:
Real-time monitoring and data acquisition COD sensors can monitor the COD content in water bodies in real time and continuously. Compared with traditional sampling methods, COD sensors are fast and accurate, without manual sampling and laboratory testing, which greatly saves time and labor costs. By combining with the data acquisition system, the monitoring data can be uploaded to the cloud in real time to form a extemporization distribution map of the COD content in the water body, providing detailed data support for environmental monitoring and management.
Pollution event warning and rapid response COD sensors play an important role in early warning and rapid response in water environment monitoring. Once there is an abnormal increase in organic matter in the water body, the COD sensor can quickly detect the change in COD content and alarm through the preset threshold. This enables relevant departments to take measures at the early stage of the pollution incident to prevent the spread of pollution and protect the water environment.
Water quality assessment and pollution source tracking COD sensors play an important role in water quality assessment and pollution source tracking. By continuously monitoring the COD content in water bodies, the water quality can be evaluated and compared with national and regional water quality standards. At the same time, COD sensors can also help determine and track the location and spread of pollution sources, provide accurate data support for environmental management departments, and guide the development of pollution prevention and control work.
Application scenarios COD sensors are widely used in various water quality monitoring scenarios, including but not limited to: Sewage treatment plants: used to monitor the COD content of in fluent and effluent to ensure the effect of sewage treatment. Water source protection and management: deployed in water sources to monitor the COD content of in fluent sources. Once the water quality exceeds the set limit, the system will issue an alarm in time to ensure water quality safety. Lake and river monitoring: deployed in water bodies such as lakes and rivers to monitor the COD content of water bodies in real time.
Technical features of COD sensor COD sensor uses advanced technology, such as ultraviolet absorption method, which does not require the use of chemical reagents, avoiding the risk of contamination of chemical reagents in traditional COD detection methods, and can achieve online uninterrupted water quality monitoring, providing strong support for real-time water quality assessment. In addition, COD sensor also has the advantages of low cost, high stability, strong anti-interference ability, and convenient installation.
Summary In summary, COD sensor plays an irreplaceable role in water quality detection. It can not only provide real-time and accurate water quality data, but also quickly warn when pollution incidents occur, providing strong technical support for water quality management and environmental protection. With the advancement of technology and the popularization of applications, COD sensor will play a more important role in water quality monitoring in the future.

@ b7274d28:c99628cb
2025-05-28 00:59:49Your identity is important to you, right? While impersonation can be seen in some senses as a form of flattery, we all would prefer to be the only person capable of representing ourselves online, unless we intentionally delegate that privilege to someone else and maintain the ability to revoke it.
Amber does all of that for you in the context of #Nostr. It minimizes the possibility of your private key being compromized by acting as the only app with access to it, while all other Nostr apps send requests to Amber when they need something signed. This even allows you to give someone temporary authority to post as you without giving them your private key, and you retain the authority to revoke their permissions at any time.
nostr:npub1w4uswmv6lu9yel005l3qgheysmr7tk9uvwluddznju3nuxalevvs2d0jr5 has provided Android users with an incredibly powerful tool in Amber, and he continues to improve its functionality and ease of use. Indeed, there is not currently a comparative app available for iOS users. For the time being, this superpower is exclusive to Android.
Installation
Open up the Zapstore app that you installed in the previous stage of this tutorial series.
Very likely, Amber will be listed in the app collection section of the home page. If it is not, just search for "Amber" in the search bar.
Opening the app's page in the Zapstore shows that the release is signed by the developer. You can also see who has added this app to one of their collections and who has supported this app with sats by zapping the release.
Tap "Install" and you will be prompted to confirm you are sure you want to install Amber.
Helpfully, you are informed that several other users follow this developer on Nostr. If you have been on Nostr a while, you will likely recognize these gentlemen as other Nostr developers, one of them being the original creator of the protocol.
You can choose to never have Zapstore ask for confirmation again with apps developed by nostr:npub1w4uswmv6lu9yel005l3qgheysmr7tk9uvwluddznju3nuxalevvs2d0jr5, and since we have another of his apps to install later in this tutorial series, I recommend you toggle this on. Then tap on "Trust greenart7c3 and install app."
Just like when you installed the Zapstore from their GitHub, you will be prompted to allow the Zapstore to install apps, since Android considers it an "unknown source."
Once you toggle this on and use the back button to get back to the Zapstore, Amber will begin downloading and then present a prompt to install the app. Once installed, you will see a prompt that installation was a success and you can now open the app.
From here, how you proceed will depend on whether you need to set up a new Nostr identity or use Amber with an existing private key you already have set up. The next section will cover setting up a new Nostr identity with Amber. Skip to the section titled "Existing Nostrich" if you already have an nsec that you would like to use with Amber.
New Nostrich
Upon opening the application, you will be presented with the option to use an existing private key or create a new Nostr account. Nostr doesn't really have "accounts" in the traditional sense of the term. Accounts are a relic of permissioned systems. What you have on Nostr are keys, but Amber uses the "account" term because it is a more familiar concept, though it is technically inaccurate.
Choose "Create a new Nostr account" and you will be presented with a screen telling you that your Nostr account is ready. Yes, it was really that easy. No email, no real name, no date of birth, and no annoying capcha. Just "Create a new account" and you're done.
The app presents you with your public key. This is like an address that can be used to find your posts on Nostr. It is 100% unique to you, and no one else can post a note that lists this npub as the author, because they won't have the corresponding private key. You don't need to remember your npub, though. You'll be able to readily copy it from any Nostr app you use whenever you need it.
You will also be prompted to add a nickname. This is just for use within Amber, since you can set up multiple profiles within the app. You can use anything you want here, as it is just so you can tell which profile is which when switching between them in Amber.
Once you've set your nickname, tap on "Continue."
The next screen will ask you what Amber's default signing policy should be.
The default is to approve basic actions, referring to things that are common for Nostr clients to request a signature for, like following another user, liking a post, making a new post, or replying. If you are more concerned about what Amber might be signing for on your behalf, you can tell it to require manual approval for each app.
Once you've made your decision, tap "Finish." You will also be able to change this selection in the app settings at any time.
With this setup out of the way, you are now presented with the main "Applications" page of the app.
At the top, you have a notification encouraging you to create a backup. Let's get that taken care of now by tapping on the notification and skipping down to the heading titled "Backing Up Your Identity" in this tutorial.
Existing Nostrich
Upon opening the application, you will be presented with the option to use your private key or create a new Nostr account. Choose the former.
The next screen will require you to paste your private key.
You will need to obtain this from whatever Nostr app you used to create your profile, or any other Nostr app that you pasted your nsec into in the past. Typically you can find it in the app settings and there will be a section mentioning your keys where you can copy your nsec. For instance, in Primal go to Settings > Keys > Copy private key, and on Amethyst open the side panel by tapping on your profile picture in the top-left, then Backup Keys > Copy my secret key.
After pasting your nsec into Amber, tap "Next."
Amber will give you a couple options for a default signing policy. The default is to approve basic actions, referring to things that are common for Nostr clients to request a signature for, like following another user, liking a post, making a new post, or replying. If you are more concerned about what Amber might be signing for on your behalf, you can tell it to require manual approval for each app.
Once you've made your decision, tap "Finish." You will also be able to change this selection in the app settings at any time.
With this setup out of the way, you are now presented with the main "Applications" page of the app. You have nothing here yet, since you haven't used Amber to log into any Nostr apps, but this will be where all of the apps you have connected with Amber will be listed, in the order of the most recently used at the top.
Before we go and use Amber to log into an app, though, let's make sure we've created a backup of our private key. You pasted your nsec into Amber, so you could just save that somewhere safe, but Amber gives you a few other options as well. To find them, you'll need to tap the cog icon at the bottom of the screen to access the settings, then select "Backup Keys."
Backing Up Your Identity
You'll notice that Amber has a few different options for backing up your private key that it can generate.
First, it can give you seed words, just like a Bitcoin seed. If you choose that option, you'll be presented with 12 words you can record somewhere safe. To recover your Nostr private key, you just have to type those words into a compatible application, such as Amber.
The next option is to just copy the secret/private key in its standard form as an "nsec." This is the least secure way to store it, but is also the most convenient, since it is simple to paste into another signer application. If you want to be able to log in on a desktop web app, the browser extension Nostr signers won't necessarily support entering your 12 word seed phrase, but they absolutely will support pasting in your nsec.
You can also display a QR code of your private key. This can be scanned by Amber signer on another device for easily transferring your private key to other devices you want to use it on. Say you have an Android tablet in addition to your phone, for instance. Just make sure you only use this function where you can be certain that no one will be able to get a photograph of that QR code. Once someone else has your nsec, there is no way to recover it. You have to start all over on Nostr. Not a big deal at this point in your journey if you just created a Nostr account, but if you have been using Nostr for a while and have built up a decent amount of reputation, it could be much more costly to start over again.
The next options are a bit more secure, because they require a password that will be used to encrypt your private key. This has some distinct advantages, and a couple disadvantages to be aware of. Using a password to encrypt your private key will give you what is called an ncryptsec, and if this is leaked somehow, whoever has it will not necessarily have access to post as you on Nostr, the way they would if your nsec had been leaked. At least, not so long as they don't also have your password. This means you can store your ncryptsec in multiple locations without much fear that it will be compromised, so long as the password you used to encrypt it was a strong and unique one, and it isn't stored in the same location. Some Nostr apps support an ncryptsec for login directly, meaning that you have the option to paste in your ncryptsec and then just log in with the password you used to encrypt it from there on out. However, now you will need to keep track of both your ncryptsec and your password, storing both of them safely and separately. Additionally, most Nostr clients and signer applications do not support using an ncryptsec, so you will need to convert it back to a standard nsec (or copy the nsec from Amber) to use those apps.
The QR option using an ncryptsec is actually quite useful, though, and I would go this route when trying to set up Amber on additional devices, since anyone possibly getting a picture of the QR code is still not going to be able to do anything with it, unless they also get the password you used to encrypt it.
All of the above options will require you to enter the PIN you set up for your device, or biometric authentication, just as an additional precaution before displaying your private key to you.
As for what "store it in a safe place" looks like, I highly recommend a self-hosted password manager, such as Vaultwarden+Bitwarden or KeePass. If you really want to get wild, you can store it on a hardware signing device, or on a steel seed plate.
Additional Settings
Amber has some additional settings you may want to take advantage of. First off, if you don't want just anyone who has access to your phone to be able to approve signing requests, you can go into the Security settings add a PIN or enable biometrics for signing requests. If you enable the PIN, it will be separate from the PIN you use to access your phone, so you can let someone else use your phone, like your child who is always begging to play a mobile game you have installed, without worrying that they might have access to your Nostr key to post on Amethyst.
Amber also has some relay settings. First are the "Active relays" which are used for signing requests sent to Amber remotely from Nostr web apps. This is what enables you to use Amber on your phone to log into Nostr applications on your desktop web browser, such as Jumble.social, Coracle.social, or Nostrudel.ninja, eliminating your need to use any other application to store your nsec whatsoever. You can leave this relay as the default, or you can add other relays you want to use for signing requests. Just be aware, not all relays will accept the notes that are used for Nostr signing requests, so make sure that the relay you want to use does so. In fact, Amber will make sure of this for you when you type in the relay address.
The next type of relays that you can configure in Amber are the "Default profile relays." These are used for reading your profile information. If you already had a Nostr identity that you imported to Amber, you probably noticed it loaded your profile picture and display name, setting the latter as your nickname in Amber. These relays are where Amber got that information from. The defaults are relay.nostr.band and purplepag.es. The reason for this is because they are aggregators that look for Nostr profiles that have been saved to other relays on the network and pull them in. Therefore, no matter what other relay you may save your profile to, Amber will likely be able to find it on one of those two relays as well. If you have a relay you know you will be saving your Nostr profiles to, you may want to add it to this list.
You can also set up Amber to be paired with Orbot for signing over Tor using relays that are only accessible via the Tor network. That is an advanced feature, though, and well beyond the scope of this tutorial.
Finally, you can update the default signing policy. Maybe after using Amber for a while, you've decided that the choice you made before was too strict or too lenient. You can change it to suit your needs.
Zapstore Login
Now that you are all set up with Amber, let's get you signed into your first Nostr app by going back to the Zapstore.
From the app's home screen, tap on the user icon in the upper left of the screen. This will open a side panel with not much on it except the option to "sign in." Go ahead and tap on it.
You will be presented with the option to either sign in with Amber, or to paste your npub. However, if you do the latter, you will only have read access, meaning you cannot zap any of the app releases. There are other features planned for the Zapstore that may also require you to be signed in with write access, so go ahead and choose to log in with Amber.
Your phone should automatically switch to Amber to approve the sign-in request.
You can choose to only approve basic actions for Zapstore, require it to manually approve every time, or you can tell it that you "fully trust this application." Only choose the latter option with apps you have used for a while and they have never asked you to sign for anything suspicious. For the time being, I suggest you use the "Approve basic actions" option and tap "Grant Permissions."
Your phone will switch back to the Zapstore and will show that you are now signed in. Congratulations! From here on out, logging into most Nostr applications will be as easy as tapping on "Log in with Amber" and approving the request.
If you set up a new profile, it will just show a truncated version of your npub rather than the nickname you set up earlier. That's fine. You'll have an opportunity to update your Nostr profile in the next tutorial in this series and ensure that it is spread far and wide in the network, so the Zapstore will easily find it.
That concludes the tutorial for Amber. While we have not covered using Amber to log into Nostr web apps, that is outside the scope of this series, and I will cover it in an upcoming tutorial regarding using Amber's remote signer options in detail.
Since you're already hanging out in the Zapstore, you may as well stick around, because we will be using it right out the gate in the next part of this series: Amethyst Installation and Setup. (Coming Soon)

2025-05-27 09:21:53The 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.

2025-05-28 08:25:13The oil-in-water sensoris an instrument specially used to detect oil substances in water bodies. Its working principle is mainly based on the characteristic that oil substances will produce fluorescence under ultraviolet light. The following is a detailed explanation:
Principle Overview The oil-in-water sensor uses the characteristic that oil substances will produce fluorescence under ultraviolet light, and measures the fluorescence intensity to infer the concentration of oil substances. Specifically, the sensor uses ultraviolet light as the excitation light source to irradiate the water sample to be tested. After the oil substance absorbs ultraviolet light, it will stimulate fluorescence, and the fluorescence signal is received by the photo detector and converted into an electrical signal. By measuring the strength of the electrical signal, the concentration of oil substances in the water sample can be inferred.
Workflow Ultraviolet light irradiation: The ultraviolet light source inside the sensor emits ultraviolet light and irradiates it into the water sample to be tested.
Fluorescence generation: After the oil substance in the water sample absorbs ultraviolet light, it will stimulate fluorescence.
Fluorescence detection: The photo detector in the sensor measures the intensity of this fluorescence.
Signal conversion: The signal processing circuit converts the output of the photo detector into an electrical signal proportional to the amount of oil in the water. Data analysis: By analyzing the strength of the electrical signal, the concentration of oil substances in the water sample can be obtained.
Features and applications The oil in water sensor has high sensitivity and can detect soluble and falsifiable oils. It is suitable for a variety of water quality monitoring scenarios, such as oil field monitoring, industrial circulating water, condensate water, wastewater treatment, surface water stations, etc. In addition, it can also monitor the content of crude oil (benzene and benzene homologous) in water sources such as reservoirs and water plants in real time online, play an early warning role, and protect the safety of water sources.
Practical application The oil in water sensor has a wide range of functions in practical applications, including but not limited to the following aspects: Monitoring the water quality of water sources: ensuring the safety of drinking water, and timely discovering pollution sources and ensuring water supply safety by continuously monitoring oil substances in water sources. Monitoring sewage treatment plant emissions: ensuring that the discharge water quality of sewage treatment plants meets the emission standards to avoid secondary pollution to the environment. Monitoring rivers, lakes and other water bodies: assessing the pollution status and providing a basis for pollution control. Early warning and emergency response: It has real-time monitoring and early warning functions, and can issue an alarm in time when abnormal conditions are found, providing valuable time for emergency response and reducing losses caused by pollution. Scientific research: Through the monitoring data of this sensor, we can deeply understand the distribution, migration and transformation of oil substances in water bodies, and provide a scientific basis for environmental protection and governance.
In summary, the oil in water sensor monitors the oil content in water bodies through ultraviolet fluorescence method, has high sensitivity and broad application prospects, and is an indispensable and important tool in modern environmental monitoring and industrial production.

2025-05-28 08:10:17The control of residual chlorine in swimming pools is an important part of water quality management, which aims to ensure the sanitation and safety of swimming pool water while avoiding discomfort to swimmers. Here are some key points about residual chlorine control in swimming pools:
Standards for residual chlorine According to the regulations of the national health supervision department, the residual chlorine in swimming pool water should be kept between 0.3mg/L-1.5mg/L. This range can not only ensure effective disinfection, but also avoid irritation to swimmers' skin and eyes caused by excessive residual chlorine. Too low residual chlorine will lead to incomplete disinfection and increase the risk of bacterial growth; while too high residual chlorine may cause human discomfort and even poisoning.
The role of residual chlorine Residual chlorine is a residual disinfectant in swimming pool water, usually in the form of sodium hypocrite (NaClO). It has strong oxidizing properties and can effectively kill bacteria, viruses and other microorganisms in water, thereby ensuring the health of swimmers. In addition, residual chlorine can eliminate harmful substances such as organic matter and ammonia in water to keep the water clean.
Residual chlorine detection method The method of detecting residual chlorine in swimming pools usually uses test strips or test kits for qualitative or quantitative detection. In addition, online monitoring instruments can be used to monitor the residual chlorine in the swimming pool in real time. These methods can help managers promptly detect and deal with situations where the residual chlorine content is too high or too low, ensuring that the water quality of the swimming pool meets the standards.
Methods for controlling residual chlorine Reasonable addition of disinfectants: According to the water quality of the swimming pool and the number of swimmers, reasonable addition of disinfectants to control the residual chlorine content within the specified range.
Regular testing: Regularly test the residual chlorine in the swimming pool to promptly detect and deal with situations where the residual chlorine content is too high or too low.
Maintain swimming pool equipment: Regularly check and maintain swimming pool equipment to ensure the water treatment effect and circulation filtration are normal, and reduce residual disinfectants and other harmful substances in the water.
Do a good job in swimmer hygiene management: Strengthen swimmer hygiene management, require swimmers to shower and rinse their feet before entering the pool, and reduce pollution sources entering the swimming pool.
Solution for excessive residual chlorine If the residual chlorine content in the swimming pool exceeds the standard range, the following measures can be taken:
Use decorating agent: Use decorating agent to quickly restore the excessive residual chlorine in the swimming pool to the normal range (0.3~0.5mg/L). This method is applicable to excessive residual chlorine caused by excessive addition of chlorine disinfectant.
Adjust the water treatment process: According to the water quality, adjust the water treatment process appropriately, such as selecting the appropriate type and dosage of disinfectant, and adjusting operating parameters such as flow rate, pH value, etc., to reduce the generation of residual chlorine.
Strengthen equipment maintenance: Regularly maintain and maintain the water treatment equipment of the swimming pool to ensure its normal operation and disinfection effect.
Through the above methods, the residual chlorine content in the swimming pool can be effectively controlled to ensure water quality safety and protect the health of swimmers.

2025-05-27 23:57:01Quando adolescente eu acreditava na coerência da teoria de "amor líquido" do polonês, sociólogo, Zygmunt Bauman, apresentada no livro "Amor Líquido: Sobre a Fragilidade dos Laços Humanos", qual no meu amadurecimento em estudos, sejam eles no meio acadêmico ou fora, percebo como uma das formas mais rasas de explicar as mudanças e transformações dos padrões de relações sócio-afetivas dos humanos. A seguir colocar-me-ei na minha juventude não tanto recente, direi então que nós, se adolescentes e conservadores, ou mesmo jovens adultos mais conservadores, costumamos levar como dogma uma óptica decadentista generalizada de todos os avanços de eras dos homens, universalizamos por nos ser comum a indistinção entre humanidade e humanidades, ou mesmo "humanity" e "humankind" ("humanidade" como espécime e "humanidade" como um universal), compreendemos toda "essas" como "essa" e indistinguimos as sociedades para com os homens, ou seja, a incapacidade de definir os seres dentro de suas respectivas singularidades e especificidades nos leva ao decadentismo generalista (a crença de que de forma geral, e universal, a "civilização universal" decai moralmente, éticamente, materialmente e espiritualmente), que aparente à nós determinadas mudanças nas relações humanas quanto ao caráter sócio-afetivo, por falta de profundidade e critérios ainda sobre questões alinhadas aos métodos e coerências, ou incoerências, lógicas, nós se jovens e conservadores somos levados ao engodo de concordar com a teoria do amor líquido de Bauman, que devo cá explicar de antemão: trata ela, a teoria, o padrão de "amor" dos tempos presentes como frágil, de prazo (curto e médio) e diferente em grau comparativamente ao amor comum das eras passadas.
Aos jovens mais progressistas opera uma compreensão dialética sobre as eras dos homens nos seu tempo presente, na qual ao tempo que o ser progride ele também regride simultaneamente, ou seja, a medida que aparecem contradições advindas de transformações materiais da realidade humana o ser supera essas contradições e progride em meio as transformações, ainda fazendo parte da lógica dessa indissociavelmente, assim constantemente progredindo e regredindo, havendo para esses dois vetores de distinção: o primeiro é o que releva questões espirituais como ao caráter do pensamento "new age", o segundo ignora essas questões por negar a existência da alma, seguem ao materialismo. Cedem em crer na teoria baumaninana como dogma, pois não encontram outros meios para explicar as transformações da sociedade na esfera sócio-afetiva sem que haja confrontamento direto com determinadas premissas assim pertinemente presentes, ou por não conciliarem com análises relativamente superiores, como a de Anthony Giddens sobre a "relação pura" em "A Transformação da Intimidade" e de François de Singly apresentada em "Sociologie du Couple".

Há um problema quando uma teoria deixa de assim ser para vir a tornar-se mais um elemento desconexo da ciência, agora dentro da cultura pop, se assim podemos dizer, ou da cultura de massa, ou se preferirem mesmo "anticultura", esse problema é a sua deformização teórica, tornando-se essa rasa para sua palatabilidade massiva, somada a incapacidade de partes da sociedade civil em compreender as falhas daquilo que já foi massificado. Tive surpresa ao entender que muitos outros compartilham da mesma opinião, a exemplo, possuo um amigo na faculdade, marxista, que ao falarmos sobre nossos projetos de pesquisa, citou ele o projeto de um de nossos colegas, no qual esse referido um de nossos colegas faria seu projeto com base na teoria do amor líquido de Bauman, então alí demos risada disso, ora, para nós a teoria baumaniana é furada, passamos a falar sobre Bauman e o motivo pelo qual não gostávamos, lá fiquei até surpreso em saber que mais gente além de mim não gostava da teoria de Bauman, pois ao que eu via na internet era rede de enaltecimentos à figura e à sua teoria, tal como fosse uma revelação partindo de alguma divindade da Idade do Bronze. Pouco tempo depois tive em aula de teoria política uma citação de Bauman partindo do professor que ministrava a disciplina, no entanto, ao citar o nome de Bauman o mesmo fez uma feição na qual aparentava segurar risada, provavelmente ele também não levava Bauman à sério. Não devo negar que todas as vezes que vejo o sociólogo sendo citado em alguma nota no X, no Instagram ou qualquer outra rede social, tal como fosse um referencial teórico bom, sinto uma vergonha alheia pois alí tenho uma impressão de que a pessoa não leu Bauman e usa o referencial teórico como um fato já assim provado e comprovado.
Há pontos positivos na teoria baumaniana, como a capacidade de perceber o problema e correlacioná-lo à modernidade, assim como sucitar a influência do que há de material no fenômeno, porém os erros são pertinentes: o primeiro problema é de categoria. Não há, por parte de Bauman noção alguma entre as dissociações dos amores, não há atenção sobre o amor como estrutura ou ele como um sentimento, todo ele é compreendido uniformemente como "amor", partindo do pressuposto que todas as relações, todas elas, são firmadas com base no amor. Essa crença tem uma origem: Hegel. Nos Escritos Teológicos Hegel partia da crença que o amor ligava os seres relacionalmente como uma força de superação e alienação, mas há de compreendermos que esse Friedrich Hegel é o jovem ainda pouco maduro em suas ideias e seu sistema de pensamento, mais a frente, em "Fenomenologia do Espírito e na Filosofia do Direito", Hegel compreende a institucionalidade do direito no amor e a institucionalização dessa força, assim aproxima-se da realidade a respeito da inserção do amor nas esferas práticas do humano, porém essa ideia, apesar de imperfeita, pois ao que sabemos não é o amor que consolida a relação, mas sim a Verdade (Alétheia), conforme apontado por Heidegger em "Ser e Tempo", essa ideia do amor como a fundamento das relações humanas influenciou, e até hoje influencia, qualquer análise sobre as relações humanas fora da esfera materialista, fora dessa pois, melhormente explicado em exemplo, os marxistas (em exemplo), assim como Marx, consideram como base primordial das relações as condições materiais.
Por certo, não é de todo amor a base para a solidificação, ora, erram aqueles que creem que somente essa força, assim apontada por Hegel, constituiam todos os relacionamentos formais como pilares fundamentais, pois em prática as famílias eram até a fiduciarização dessas, por mais paradoxal que seja, compreendidas melhor como instituições orgânicas de caráter legal do que conluios de afetividades. A família outrora tinha consigo aparelhos de hierarquia bem estabelicidos, quais prezavam pela ordem interna e externa, que acima dessa instituição estava somente a Igreja (outra instituição), com sua fiduciarização [da família] após o movimento tomado pelos Estados nacionais em aplicação do casamento civil mudou-se a lógica das partes que a compõe, findou-se o princípio da subsidiariedade (não intervenção de determinadas instituições nas decisões quais podem ser exercidas em resuluções de problemas nas competências de quaisquer instituições), foi-se então, contudo, também a autoridade, e nisso revela-se um outro problema não apontado na teoria de Bauman: qual o padrão do amor "sólido"? Pois, ora, sociedades tradicionais não abdicavam do relevar dos amores para tornar seus filhos em ativos nas práticas de trocas (dádivas)? É notório que esse padrão se dissocia do padrão de sentimento apontado por Bauman, encontramos esse fato em estudo nos trabalhos "Ensaio Sobre a Dádiva", do Marcel Mauss, e "As Estruturas Elementares do Parentesco", do Claude Levi-Strauss, quais expõem que nas sociedades "sólidas", tradicionais, relevava-se mais questões institucionais que as sentimentais para a formação de laços (teoria da aliança). Muitas das relações passadas não eram baseadas no amor, não significando assim que as de hoje, em oposição, sejam, mas que permanecem-se semelhantes em base, diferentemente em grau e forma.
https://substackcdn.com/image/fetch/f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F748b94c3-f882-45db-8333-09260ef15cfe_615x413.jpeg
Ora, ainda existem casamentos motivados pela política, pelo status, pelo prestígio, pelos bens, pelo poder, pela influência familiar e assim sucetivamente, tal como no passado, ocorre que essa prática tornou-se oculta, não mais explícita e aparente, devo dizer ainda que em partes, pois prepondera em nosso tempo uma epidemia de adultérios, fornicações, práticas lascivas e demais práticas libertinosas explicitamente, em contraposição às práticas ocultas em vergonhas de sociedades sem declínio moral e espiritual, o que nos leva a questionar o método comparativo em dicotomia temporal "presente x passado" aplicado por Bauman, no qual segue-se da seguinte forma:
Transformação Passado = *sólido* | Presente = *líquido* Categorias Padrão de amor: tradicional (*sólido*) moderno (*líquido*) *Sólido* = estável, prazo (médio-grande), profundo, determinado. *Líquido* = instável, prazo (curto-médio), raso, indeterminado.
O que penso é: Zygmunt Bauman buscou uma explicação material e laical para desviar ao fato de que há uma notória correlação entre espiritualização da sociedade, se voltada à Verdade, com a estabilidade das instituições, o que é já reduzido à moral religiosa, somente, não à mística, como por pensadores da linha de Tocqueville, ou em abordagens também mais laical (positivista) porém ainda relevantes, como Émile Durkheim em "As Formas Elementares da Vida Religiosa" e Max Weber em "A Ética Protestante e o Espírito do Capitalismo", contrapondo uma abordage mais voltada, de fato, a espiritualidade, como Christopher Dawnson, que defende essa teoria em "Religião e o Surgimento da Cultura Ocidental", e Eric Voegelin, principalmente nas obras "A Nova Ciência da Política" e "Ordem e História".
Encerrando, minha cosmovisão é a católica, o sistema de crença e religião qual sigo é do Deus que se fez homem por amor aos seus filhos, não posso negar ou mesmo omitir o fato de que, por trás de toda a minha crítica estão meus pensamentos e minhas convicções alinhadas àquilo que mais tenho amor em toda minha vida: a Verdade, e a Verdade é Deus, pois Cristo é a Verdade, o Caminho e a Vida, ninguém vai ao Pai se não por Ele, e pois bem, seria incoerência de minha parte não relevar o fato de crença como um dos motivos pelos quais eu rejeito a teoria do amor líquido de Zygmunt Bauman, pois os amores são todos eles praticados por formas, existem por diferentes formas e assim são desde sua tradicionalidade até o predomínio das distorções de declínio espiritual das eras presentes (e também antigas pré-Era Axial), estão esses preservados pelo alinhamento à verdade, assim são indistorcíveis, imutáveis, ou seja, amor é amor, não releva-se o falso amor como um, simplesmente não o é, assim o interesse, a sanha por bens, o egoísmo e a egolatria ("cupiditas", para Santo Agostinho de Hipona, em oposição ao que o santo e filósofo trata por "caritas") não são formas do amor, são autoenganos, não bons, se não são bons logo não são de Deus, ora, se Deus é amor, se ele nos ama, determino como amor (e suas formas) o que está de acordo com a Verdade. Aprofundando, a Teologia do Corpo, do Papa São João Paulo II, rejeita a "liquidez" apresentada por Bauman, pois o amor é, em suma, sacríficio, parte da entrega total de si ao próximo, e se não há logo não é amor. A Teologia do Corpo rejeita não os fundamentos de mentira no "líquido", mas também no "sólido", pois a tradicionalidade não é sinônimo de bom e pleno acordo com o amor que Deus pede de nós, não são as coerções, as violências, as imposições e demais vontades em oposição às de Deus que determinam os amores -- fatos em oposição ao ideário romanticizado. Claro, nem todas as coerções são por si inválidas do amor, ou mesmo as escolhas em trocas racionalizadas, a exemplo do autruísmo em vista da chance da família ter êxito e sucesso, ou seja, pelo bem dos próximos haver a necessidade de submissão a, em exemplo, um casamento forjado, ou algo do gênero, reconhece-se o amor no ato se feito por bem da família, porém o amor incutido, nesse caso, explicita o caráter sacrificial, no qual uma vontade e um amor genuinamente potencial em prazeres e alegrias são anulados, ou seja, mesmo nesse modelo tradicional na "solidez" há possibilidade do amor, não nas formas romanticizadas em critérios, como "estabilidade" e "durabilidade", mas no caráter do sacríficio exercido. Conforme nos ensina São Tomás de Aquino, o amor não é uma "força", tal como ensina Hegel, mas sim uma virtude teologal conforme na "Suma Teológica" (II-II Q. 26-28), não devemos reduzir o amor e os amores em análises simplórias (não simples) de falsa complexidade extraídas em métodos questionáveis e pouco competentes à real diensão de crise espiritual das eras, por esse motivo não concordo com a teoria do amor líquido de Zygmunt Bauman.

2025-05-27 09:21:51Know Your Customer is a regulation that requires companies of all sizes to verify the identity, suitability, and risks involved with maintaining a business relationship with a customer. Such procedures fit within the broader scope of anti-money laundering (AML) and counterterrorism financing (CTF) regulations.
Banks, exchanges, online business, mail providers, domain registrars... Everyone wants to know who you are before you can even opt for their service. Your personal information is flowing around the internet in the hands of "god-knows-who" and secured by "trust-me-bro military-grade encryption". Once your account is linked to your personal (and verified) identity, tracking you is just as easy as keeping logs on all these platforms.
Rights for Illusions
KYC processes aim to combat terrorist financing, money laundering, and other illicit activities. On the surface, KYC seems like a commendable initiative. I mean, who wouldn't want to halt terrorists and criminals in their tracks?
The logic behind KYC is: "If we mandate every financial service provider to identify their users, it becomes easier to pinpoint and apprehend the malicious actors."
However, terrorists and criminals are not precisely lining up to be identified. They're crafty. They may adopt false identities or find alternative strategies to continue their operations. Far from being outwitted, many times they're several steps ahead of regulations. Realistically, KYC might deter a small fraction – let's say about 1% ^1 – of these malefactors. Yet, the cost? All of us are saddled with the inconvenient process of identification just to use a service.
Under the rhetoric of "ensuring our safety", governments and institutions enact regulations that seem more out of a dystopian novel, gradually taking away our right to privacy.
To illustrate, consider a city where the mayor has rolled out facial recognition cameras in every nook and cranny. A band of criminals, intent on robbing a local store, rolls in with a stolen car, their faces obscured by masks and their bodies cloaked in all-black clothes. Once they've committed the crime and exited the city's boundaries, they switch vehicles and clothes out of the cameras' watchful eyes. The high-tech surveillance? It didn’t manage to identify or trace them. Yet, for every law-abiding citizen who merely wants to drive through the city or do some shopping, their movements and identities are constantly logged. The irony? This invasive tracking impacts all of us, just to catch the 1% ^1 of less-than-careful criminals.
KYC? Not you.
KYC creates barriers to participation in normal economic activity, to supposedly stop criminals. ^2
KYC puts barriers between many users and businesses. One of these comes from the fact that the process often requires multiple forms of identification, proof of address, and sometimes even financial records. For individuals in areas with poor record-keeping, non-recognized legal documents, or those who are unbanked, homeless or transient, obtaining these documents can be challenging, if not impossible.
For people who are not skilled with technology or just don't have access to it, there's also a barrier since KYC procedures are mostly online, leaving them inadvertently excluded.
Another barrier goes for the casual or one-time user, where they might not see the value in undergoing a rigorous KYC process, and these requirements can deter them from using the service altogether.
It also wipes some businesses out of the equation, since for smaller businesses, the costs associated with complying with KYC norms—from the actual process of gathering and submitting documents to potential delays in operations—can be prohibitive in economical and/or technical terms.
You're not welcome
Imagine a swanky new club in town with a strict "members only" sign. You hear the music, you see the lights, and you want in. You step up, ready to join, but suddenly there's a long list of criteria you must meet. After some time, you are finally checking all the boxes. But then the club rejects your membership with no clear reason why. You just weren't accepted. Frustrating, right?
This club scenario isn't too different from the fact that KYC is being used by many businesses as a convenient gatekeeping tool. A perfect excuse based on a "legal" procedure they are obliged to.
Even some exchanges may randomly use this to freeze and block funds from users, claiming these were "flagged" by a cryptic system that inspects the transactions. You are left hostage to their arbitrary decision to let you successfully pass the KYC procedure. If you choose to sidestep their invasive process, they might just hold onto your funds indefinitely.
Your identity has been stolen
KYC data has been found to be for sale on many dark net markets^3. Exchanges may have leaks or hacks, and such leaks contain very sensitive data. We're talking about the full monty: passport or ID scans, proof of address, and even those awkward selfies where you're holding up your ID next to your face. All this data is being left to the mercy of the (mostly) "trust-me-bro" security systems of such companies. Quite scary, isn't it?
As cheap as $10 for 100 documents, with discounts applying for those who buy in bulk, the personal identities of innocent users who passed KYC procedures are for sale. ^3
In short, if you have ever passed the KYC/AML process of a crypto exchange, your privacy is at risk of being compromised, or it might even have already been compromised.
(they) Know Your Coins
You may already know that Bitcoin and most cryptocurrencies have a transparent public blockchain, meaning that all data is shown unencrypted for everyone to see and recorded forever. If you link an address you own to your identity through KYC, for example, by sending an amount from a KYC exchange to it, your Bitcoin is no longer pseudonymous and can then be traced.
If, for instance, you send Bitcoin from such an identified address to another KYC'ed address (say, from a friend), everyone having access to that address-identity link information (exchanges, governments, hackers, etc.) will be able to associate that transaction and know who you are transacting with.
Conclusions
To sum up, KYC does not protect individuals; rather, it's a threat to our privacy, freedom, security and integrity. Sensible information flowing through the internet is thrown into chaos by dubious security measures. It puts borders between many potential customers and businesses, and it helps governments and companies track innocent users. That's the chaos KYC has stirred.
The criminals are using stolen identities from companies that gathered them thanks to these very same regulations that were supposed to combat them. Criminals always know how to circumvent such regulations. In the end, normal people are the most affected by these policies.
The threat that KYC poses to individuals in terms of privacy, security and freedom is not to be neglected. And if we don’t start challenging these systems and questioning their efficacy, we are just one step closer to the dystopian future that is now foreseeable.
Edited 20/03/2024 * Add reference to the 1% statement on Rights for Illusions section to an article where Chainalysis found that only 0.34% of the transaction volume with cryptocurrencies in 2023 was attributable to criminal activity ^1

2025-05-28 07:50:06Soil moisture is a key factor that affects the structure and function of soil microbial communities. Here are some of the main aspects of how soil moisture affects microorganisms:
Affecting the Growth and Metabolism of Microorganisms Changes in soil moisture content directly affect the growth and metabolic activities of microorganisms. Under suitable moisture conditions, microorganisms are better able to carry out metabolic activities, thereby promoting the decomposition of soil organic matter and the transformation of nutrients. However, under extremely dry or overly wet conditions, the activity of microorganisms will be inhibited, resulting in a decline in soil functions.
Changing the Structure of Microbial Communities Changes in soil moisture conditions can lead to significant changes in the structure of microbial communities. For example, under drought conditions, the number of drought-tolerant microorganisms may increase to adapt to the water shortage environment. While under wet conditions, aerobic microorganisms may dominate. This change in community structure not only affects the soil's water retention capacity, but also other ecological functions of the soil.
Affecting the Stability of Soil Aggregates Soil aggregates are clumps formed by soil particles through physical, chemical and biological actions, and they have an important impact on the soil's water retention capacity. Soil microorganisms participate in the formation and stability of soil aggregates by secreting substances such as extracellular polymers. Appropriate soil moisture helps maintain the stability of soil aggregates, thereby improving the soil's water retention capacity. However, excessive moisture or drought may lead to the destruction of soil aggregates and reduce the soil's water retention capacity.
Regulating soil moisture dynamics Soil microorganisms can regulate the dynamic balance of soil moisture through their metabolic activities, such as decomposing organic matter and synthesizing exopolysaccharides. For example, some microorganisms can increase the water holding capacity of the soil by secreting exopolysaccharides, while others can release water by decomposing organic matter. These activities help maintain the stability of soil moisture and support plant growth.
Influencing the physical properties of soil Soil moisture can also indirectly affect the living environment of microorganisms by affecting the physical properties of the soil, such as pore structure and texture. Good soil pore structure is conducive to the penetration and storage of water, and also provides a suitable living space for microorganisms. Soil texture is closely related to the stability of aggregates. Sandy soils have poor aggregate stability and weak water retention capacity; while clay soils have good aggregate stability and strong water retention capacity.
In summary, soil moisture has many effects on microorganisms, including affecting the growth and metabolism of microorganisms, changing the structure of microbial communities, affecting the stability of soil aggregates, regulating soil moisture dynamics, and affecting the physical properties of soil. Therefore, maintaining suitable soil moisture conditions is of great significance for protecting the diversity and function of soil microbial communities and improving the water retention capacity of soil.

- Procena vrednosti
- Većina Bitcoin-ovih pozitivnih strana opstaje
- Broj ljudi koji su prihvatili Bitcoin
- Zaključak
Prošlo je trinaest godina od nastanka Bitcoina i lako je poverovati da je većina njegovog rasta iza njega. Deo ovoga je rezultat predrasude koju svi delimo i što nas navodi da zamislimo trenutno stanje stvari kao završni stepen njegovog razvoja. Svaki bitcoiner je nekad mislio da je prekasan sa Bitcoin-om. Međutim, kada primenjujemo kritičko razmišljanje da bismo procenili gde je Bitcoin u svojoj putanji rasta, otkrivamo da je suprotno u stvari tačno: još uvek je vrlo, vrlo rano.
Postoje dva načina da razmišljate o tome koliko je rano za Bitcoin kao zalihu vrednosti neke imovine:
-
Procena vrednosti kao procenat od njegovog punog potencijala
-
Prihvatanje kao procenat od njegovog punog potencijala (na čemu je fokus u ovom članku).
Procena vrednosti
Prvi i najčešći način da se proceni koliko je rano za Bitcoin je da se pogleda njegova ukupna vrednost (trenutno oko 900B USD) i uporedi sa njegovim punim potencijalom. Izazov sa ovim je očigledno da je puni potencijal Bitcoin-a stvar nagađanja. Oni koji duboko razumeju Bitcoin imaju tendenciju da njegov potencijal posmatraju barem kao potencijal zlata (oko 13T USD), ali teoretski više poput 200T USD (oko polovine ukupne vrednosti sveta).
Za brzi pregled ovog potencijala od 200T USD, pogledajmo ukupno raspoloživo tržište Bitcoin-a. Radi jednostavnosti, samo ćemo razmotriti njegovu ulogu zalihe vrednosti i zanemariti njegov potencijal da pojede tržišni udeo od oko 100T USD ukupne vrednosti u različitim svetskim valutama. Uzimajući u obzir različite zalihe vrednosne imovine i grubom procenom koliki bi % Bitcoin mogao da uzme od njih, dobili smo ovakav rezultat:
Iako put do 200T USD nije veliko rastezanje, u stvarnoj vrednosti čini se previše dobrim da bi bio istinit. Sa obzirom da je bez presedana da zaliha vrednosti neke robe postigne vrednost veću od zlata, to jednostavno predstavlja neistraženu teritoriju. Ali čak i ako se jednostavno pridržavamo targetiranja niže ciljne vrednosti zlata od 13T USD, Bitcoin još uvek tendenciju velikog porasta svoje cene u budućnosti.
Većina Bitcoin-ovih pozitivnih strana opstaje
Svako ko razmišlja da nešto svog teško zarađenog novca uskladišti u Bitcoin pita se „da li sam poranio ili zakasnio?“ Nepisano je pravilo da se svako oseća kao da je zakasnio kad stigne. Brojni su primeri ljudi koji žale kako su zakasnili 2011. ili 2013. ili 2016. godine, kada je cena Bitcoin-a bila 5, 100, odnosno 600 USD.
Kao i u bilo kojoj zajednici koja se razvija i raste i u kojoj ima manjka nekretninama, pridošlice zavide ljudima koji su već obezbedili sebi nekretninu, ne sluteći da će njima zavideti ljudi koji tek treba da dođu. Ovaj fenomen je primenjiv i na velikom broju drugih primera. Na primer, zakasneli u Kalifornijskoj zlatnoj groznici bili su razočarani kada su došli, a bogata zlatna polja su već bila iscrpljena, i umesto toga su se naseliti na nekoliko stotina hektara zemljišta, a koje sada vrede bogatstvo.
U srcu ovog osećanja je strah da više nema uspona, da više nema novca koji se može zaraditi uzimajući ono što je još uvek ostalo dostupno. Da li smo dostigli tu tačku sa Bitcoin-om?
Pa ne. Čini se da je zapravo suprotno. Na osnovu punog potencijalnog opsega procene koji smo utvrdili gore, čak i u ishodu niskog nivoa (13T USD), velika većina bogatstva koje će steći vlasnici Bitcoin-a, tek treba da se stekne (96%). Da bi parirao proceni zlata, Bitcoin i dalje mora da poraste 26 puta.
A ako se desi vrhunski ishod, punih 99,7% ukupnog stvaranja bogatstva Bitcoin-a ostaje pred nama. To bi značilo da Bitcoin još uvek treba da poraste 400 puta, zanemarujući pariranje zlatu.
Stavljanjem trenutne vrednosti Bitcoin-a u perspektivu, postaje jasno da je za Bitcoin još uvek vrlo rano.
Iako ova analiza sugeriše da za Bitcoin-u ostaje od 26x do 400x rasta, korisno je proveriti ovaj zaključak kroz drugo razumno objašnjenje, a tamo gde je poznat puni potencijal…
Broj ljudi koji su prihvatili Bitcoin
Procene broja vlasnika Bitcoin-a širom sveta se veoma razlikuju. To je dovelo do prilične količine dvosmislenosti i nesigurnosti u vezi sa stvarnim brojevima i određenog stepena odustajanja i mišljenja da je taj broj jednostavno preteško precizno proceniti. Iako je teško utvrditi konačan broj, glavni razlog za odstupanje u procenama je nedostatak standardizovanih definicija šta znači prihvatanje Bitcoin-a.
Istina je da postoje različiti nivoi prihvatanja Bitcoin-a. Podelom na segmente prihvatanja Bitcoin-a lakše je uvideti ne samo zašto postoji širok opseg procena, već i još važnije, koliko je još uvek rano za prihvatanje Bitcoin-a kao preferirane zalihe vrednosti.
U ove svrhe, hajde da podelimo u segmente prihvatanje Bitcoin-a na četiri različita „nivoa“:
1. Kežual amateri (prstom u vodi)
2. Alokatori 1% (stopalima u vodi)
3. Značajni vernici (do pojasa u vodi)
4. Bitcoin maximalisti (u vodi preko glave)
Pre nego što počnemo, potreban nam je imenilac. Mogli bismo da koristimo globalno stanovništvo, ali po mom mišljenju ovo daje loše rezultate. Ono što mi zaista procenjujemo je koji procenat sveta koji poseduje odredjeno bogatstvo za skladištenje u Bitcoin-u, je to i učinio. Prema podacima sa sajta Statista, 2,2 biliona ljudi na svetu poseduje najmanje 10k USD u neto vrednosti, što se čini kao razumna granica za zalihu koju žele da uskladište. Činjenica je da će siromašne zajednice takođe koristiti Bitcoin kao zalihu vrednosti i verovatno će iz njega izvući veću korist kao rezultat marginalnog pristupa tradicionalnoj bankarskoj infrastrukturi kao klijenti banaka sa „niskom vrednošću“. Međutim, u naše svrhe, jednostavno gledamo koliko je ljudi usvojilo Bitcoin među grupama sa značajnim bogatstvom za skladištenje, tako da će 2.2 biliona služiti kao naša puna potencijalna veličina tržišta.
1. Kežual amateri
Ovaj segment ljudi koji su prihvatili Bitcoin uključuje sve one koji imaju bilo koju količinu Bitcoin-a – vašeg prijatelja sa 20 USD BTC-a negde u nekom novčaniku ili vašu tetku koja se ne seća svoje Coinbase lozinke iz 2017. Po mom mišljenju, najveća zabuna oko broja ljudi koji su prihvatili Bitcoin nastaje zbog poistovećivanja „kežual amatera“ sa ljudima koji su u potpunosti prihvatili Bitcoin. Realnost je takva da ljudi ovog segmenta uglavnom samo eksperimentišu, bilo da bi stekli osećaj za ono o čemu svi pričaju, ili samo uložu nekoliko dolara u Bitcoin u nadi da će možda dobiti džekpot, kao što je slučaj sa greb-greb nagradnim igrama.
Zbog toga, „kežual amateri“ su razlog dovodjenja u zabludu pravog broja ljudi koji su u potpunosti prihvatili Bitcoin. Njihovo ponašanje zapravo ne predstavlja prihvatanje u pravom smislu te reči i stoga se ne bi trebalo smatrati ljudima koji su u potpunosti prihvatili Bitcoin. Istina je da, kada kežual amateri shvate da je Bitcoin najbolja zaliha vrednosti neke imovine u istoriji, neće ostati na samo 20 USD u Bitcoin-ima. Umesto toga, oni će svoju štednju prebaciti u mnogo većim iznosima.
Što se tiče odredjivanja veličine ovog segmenta, Willy Woo je sastavio razumno iscrpnu i sveobuhvatnu procenu od oko 187 miliona ljudi koji su prihvatili Bitcoin, što znači da su oni u najmanju ruku „kežual amateri“.
Koristeći ovaj i naš puni potencijal od 2,2 biliona ljudi kao imenioca, 8,5% potencijalnih ljudi koji su prihvatili Bitcoin-e dostiglo je nivo „kežual amatera“. Ovo je prilično velik broj i potpuno obmanjuje stvarni obim potpunog prihvatanja, a što će pokazati sledeći segmenti.
2. Alokatori 1%
Za preostale potkategorije, tačni podaci su manje dostupni. Kao takvi, sve što možemo je da smislimo razumne procene putem triangulacije.
Po mom mišljenju, „alokatori 1%“ se mogu okarakterisati kao ljudi koji su prihvatili Bitcoin, i koji žele da imaju mali, ali ne i zanemarljivi deo u Bitcoin-u. Za naše svrhu, mislim da je pristojan prag za ovu grupu svako ko ima najmanje 0,1 Bitcoin, i može se smatrati da imaju malu, ali ne i zanemarljivu poziciju u Bitcoin-u.
Gledajući Bitcoin blockchain, postoji oko 3 miliona adresa koje imaju najmanje 0,1 BTC. Pored ovih brojeva na blockchain-u, moramo da uzmemo u obzir i znatan broj ljudi koji imaju ovaj iznos na berzi ili GBTC-u. Kombinovanjem, mislim da je razumno proceniti da je 10 miliona ljudi dostiglo nivo „alokatora 1%“ ili veći.
Na osnovu ovih brojeva, samo 1⁄17 „kežual amatera“ dostiglo je nivo prihvatanja „alokatora 1%“, što znači da je ovaj nivo prihvatanja Bitcoin-a do danas postigao samo 0,5% penetracije. Ovaj strmi pad je razlog zašto je došlo do zablude da veliki broj „kežual amatera“ bude označeno kao grupa koja je u potpunosti prihvatila Bitcoin.
3. Značajni vernici
U ovu kategoriju spada svako ko je dostigao nivo razumevanja Bitcoin-a da alokacija od 1% ili čak 5% više ne izgleda dovoljna.
Uopšteno govoreći, ova grupa se kreće u rasponu od 5 – 50%. Išao bih toliko daleko da bih rekao da je većina ljudi koji sebe smatraju vernicima u Bitcoin-e, uključujući većinu Bitcoin Twitter-a, negde u ovoj grupi.
Procena veličine ove grupe postaje mnogo nejasnija, ali možemo se osloniti na podatke iz blockchain-a da bismo došli do razumne procene.
Za početak, hajde da utvrdimo da je većina ljudi koji su dostigli ovaj nivo verovanja i razumevanja Bitcoin-a, izborila da poseduje najmanje 1 Bitcoin. Pored toga, ovaj nivo ljudi koji su prihvatili Bitcoin je verovatno osigurao svoj Bitcoin u chain-u novčanika kojim oni upravljaju. Gledajući podatke na chain-u, oko 820k adresa ima najmanje 1 Bitcoin. Kao grubu pretpostavku, uzmimo da 500k od toga poseduju ljudi koji su dostigli nivo prihvatanja „značajnog vernika“.
Ako potom generički zaokružimo akaunte za ljude koji nisu postigli status wholecoiner-a (eng. osoba koja poseduje barem 1 BTC), ili koji svoja sredstva drže na berzi, dolazimo do grube procene od 2 miliona „značajnih vernika“.
4. Bitcoin maximalisti
Za našu svrhu, recimo da ova grupa uključuje svakoga ko je dovoljno duboko ušao u Bitcoin da je zaključio da bi više od 50% njihove neto vrednosti trebalo da bude uskladišteno u Bitcoin-u.
Procena veličine ove grupe je gotovo nemoguća, zato ćemo morati da budemo kreativni.
-
Prodaja „Bitcoin Standard“
-
Hajde da konzervativno procenimo da je samo 20% maximalističara kupilo Bitcoin Standard, i da je 50% tih ljudi koji su ga razumeli, postali maksimalisti. Na osnovu knjige Amazon US rank (6,681), onlajn kalkulatori procenjuju da je prodato oko 15k primeraka.
- Hajde da budemo velikodušni i da zaokružimo taj broj od oko 15k na 50k, uzimajući u obzir međunarodnu prodaju i kupovinu izvan Amazona.
Ovo nas dovodi do procene broja od 125k maximalista. Da ne bismo pogrešili, bićemo oprezni, i udvostručimo taj broj i rećićemo da ih ima 250k.
- Kvalitativna triangulacija
Čisto subjektivno, ali čini mi se da na Twitter-u, primarnom domu za komunikaciju maximalista, postoji možda 10k aktivno angažovanih Bitcoin maximalista. Da budemo vrlo konzervativni, recimo da ovo predstavlja oko 5% maximalista (od ukupno 200k).
Uz to, kao procenu od vrha nadole, čini se opravdanim da je oko 10% ljudi koji su dostigli 5 – 50% alokacije Bitcoin-a napravilo skok ka maximalizmu.
Sve u svemu, cifra od oko 250k Bitcoin maximalista čini se konzervativnom, ako ne i velikodušnom pretpostavkom.
To nas dovodi do 0,01% penetracije.
Zaključak
Kako god gledali brojke, još uvek je rano za Bitcoin. Posmatrajući procenu vrednosti Bitcoin-a kao procenat njegovog punog potencijala, vidimo da je trenutna vrednost Bitcoin-a negde između 0,2% i 3% njegovog krajnjeg stanja, što znači da ostaje 30x do 500x rasta. Gledajući napredak prihvatanja Bitcoin-a, vidimo da je trenutna penetracija Bitcoin-a negde između 0,01% i 8,5%, u zavisnosti od toga koji prag prihvatanja gledate.
Ako verujete, kao što ja verujem, da je Bitcoin na putu da postane dominantna zaliha vrednosti i preferirani novac za ceo svet, na kraju će norma biti više od 50% posedovanja neto vrednosti u Bitcoin-u. Budući da naša analiza ovde sugeriše da samo 0,01% sveta zadovoljava ove standarde, opravdano je zaključiti da 99,99% sveta ostaje da sledi njihov primer.
Sve u svemu, dok svi koji se pojave na Bitcoin-u neizbežno osećaju žaljenje zbog toga što nisu ranije investirali i pitaju se da li su u potpunosti propustili brod, jasno je da većina rasta Bitcoin-a ostaje pred nama. Da stavimo ovo u neki kontekst, obzirom da može postojati samo 21 milion Bitcoin-a, prosečna osoba na zemlji (od 8 biliona ljudi) imaće samo 0,0025 Bitcoin-a. Još je toliko rano, da ukupna neto vrednost te prosečne osobe u Bitcoin-u može da se kupi za samo 90 USD.
I ako mislite da je kasno, zapravo je veoma rano, zato vam čestitam i uživajte u skupljanju sats-ova dok su još uvek ovako jeftini!

Visualizar tarefas agendadas
bash atq
Remover uma tarefa agendada
bash atrm <número_da_tarefa>
Você encontra o número da tarefa com
atq
.
cron
O
cron
é um utilitário de agendamento de tarefas baseado no tempo. Permite executar comandos ou scripts automaticamente em horários específicos. Ele depende do daemoncrond
, que deve estar ativo e em execução contínua no sistema.Arquivo de configuração:
-
Cada usuário pode editar seu próprio agendador com:
bash crontab -e
-
O formato padrão de uma linha no crontab:
m h dom mon dow comando
|Campo|Descrição|Valores possíveis| |---|---|---| |m|Minuto|0–59| |h|Hora|0–23| |dom|Dia do mês|1–31| |mon|Mês|1–12| |dow|Dia da semana|0–6 (0 = Domingo)| |comando|Comando a executar|Qualquer comando shell válido|
Exemplos:
-
Executar um script a cada minuto:
bash * * * * * /usr/local/bin/execute/this/script.sh
-
Fazer backup no dia 10 de junho às 08:30:
bash 30 08 10 06 * /home/sysadmin/full-backup
-
Backup todo domingo às 5h da manhã:
bash 0 5 * * 0 tar -zcf /var/backups/home.tgz /home/
Limitações:
Tarefas agendadas com
cron
não são executadas se o computador estiver desligado ou suspenso no horário programado. O comando é simplesmente ignorado. Usecron
para tarefas com data/hora exatas.
anacron
O
anacron
é uma alternativa aocron
voltada para sistemas que não ficam ligados o tempo todo, como notebooks e desktops. Ele garante a execução de tarefas periódicas (diárias, semanais, mensais) assim que possível após o sistema ser ligado, caso tenham sido perdidas. Useanacron
para tarefas periódicas tolerantes a atrasos.Verificação da instalação:
bash anacron -V
Instalação (caso necessário):
bash sudo apt update sudo apt install anacron
Arquivo de configuração:
/etc/anacrontab
Acessado com:
sudo nano /etc/anacrontab
Formato de cada linha:
PERIOD DELAY IDENT COMMAND
| Campo | Descrição | | ------- | ------------------------------------------- | | PERIOD | Intervalo em dias (1 = diário, 7 = semanal) | | DELAY | Minutos a esperar após o boot | | IDENT | Nome identificador da tarefa | | COMMAND | Comando ou script a ser executado |
Exemplo:
bash 1 3 limpeza-temporarios /home/usuario/scripts/limpar_tmp.sh
Executa o script uma vez por dia, 3 minutos após o sistema ser ligado.
Nota: Não é necessário usar
run-parts
nemcron.daily
para tarefas personalizadas. Basta apontar diretamente para o script desejado. Orun-parts
só deve ser usado quando se deseja executar todos os scripts de um diretório.Ativação do serviço:
bash sudo systemctl enable --now anacron
Verificação de status:
bash systemctl status anacron
Logs de execução:
bash grep anacron /var/log/syslog
/etc/anacrontab
: Arquivo de Configuração doanacron
O arquivo
/etc/anacrontab
define tarefas periódicas a serem executadas peloanacron
, garantindo que comandos sejam executados mesmo que o computador esteja desligado no horário originalmente programado.Cabeçalho Padrão
bash SHELL=/bin/sh HOME=/root LOGNAME=root
-
SHELL
: Shell padrão utilizado para executar os comandos. -
HOME
: Diretório home usado durante a execução. -
LOGNAME
: Usuário associado à execução das tarefas.
Entradas Padrão do Sistema
bash 1 5 cron.daily run-parts --report /etc/cron.daily 7 10 cron.weekly run-parts --report /etc/cron.weekly @monthly 15 cron.monthly run-parts --report /etc/cron.monthly
|Campo|Significado| |---|---| |
1
|Executa a tarefa diariamente (a cada 1 dia)| |5
|Espera 5 minutos após o boot| |cron.daily
|Identificador da tarefa (usado nos logs)| |run-parts
|Executa todos os scripts dentro do diretório|Diretórios utilizados:
-
/etc/cron.daily
: scripts executados uma vez por dia -
/etc/cron.weekly
: scripts semanais -
/etc/cron.monthly
: scripts mensais
O comando
run-parts
executa automaticamente todos os scripts executáveis localizados nesses diretórios.Personalização
Para adicionar tarefas personalizadas ao
anacron
, basta adicionar novas linhas com o formato:PERIOD DELAY IDENT COMMAND
Exemplo:
bash 1 3 limpeza-temporarios /home/usuario/scripts/limpar_tmp.sh
Executa o script
limpar_tmp.sh
diariamente, com 3 minutos de atraso após o boot.Importante: Não é necessário — nem recomendado — usar
run-parts
quando a intenção é executar um script individual. Orun-parts
espera um diretório e ignora arquivos individuais. Usarrun-parts
com um script individual causará falha na execução. -
