The crypto platform had been aware of the data breach for months before the official announcement, internal sources reveal.

A Reuters investigation uncovered that Coinbase had been informed as early as January 2025 about a data breach involving outsourced customer support agents in India. Six sources familiar with the matter confirmed that the exchange knew sensitive user information had been compromised through its contractor, TaskUs, months before the formal disclosure in May.

On May 14, in a filing with the SEC, TaskUs documented part of the breach, in which an employee at its Indian office was caught photographing his work computer screen with a personal phone. Five former TaskUs workers confirmed that this employee and an alleged accomplice had been bribed by hackers to obtain Coinbase user data.

Coinbase had a long-standing partnership with TaskUs, a Texas-based outsourcing company, to reduce labor costs by assigning customer support functions to offshore teams. Since 2017, TaskUs agents handled Coinbase customer inquiries, often from lower-wage countries like India, where employees earned between $500 and $700 per month.

The financial impact of the breach

The exchange estimated that the breach could cost the company up to $400 million. In its May filing, Coinbase admitted it hadn’t fully grasped the extent of the attack until May 11, when it received a $20 million extortion demand. In response, the company terminated the TaskUs employees responsible for the breach, along with several other unnamed foreign contractors.

The Russian banking giant introduces financial instruments linked to Bitcoin for qualified investors.

Russia’s largest commercial banking institution, Sber, has made its entry into the Bitcoin space by unveiling a bond product tied to the asset.

Sber has officially launched its structured financial instrument that mirrors the price performance of Bitcoin alongside fluctuations in the dollar-ruble exchange rate. The product is already available to qualified investors through the over-the-counter (OTC) market, with plans to list it on the Moscow Exchange in the near future.

Formerly known as Sberbank, the institution stated in a May 30 announcement that the listing would provide transparency, liquidity, and convenience for a wide range of professional investors. This structured approach will allow investors to benefit both from Bitcoin’s appreciation in dollars and from the strengthening of the US dollar against the Russian ruble, the bank suggests.

The lender also announced plans to expand its crypto offering through the SberInvestments platform, introducing exchange-traded products that provide exposure to digital assets. The first product will be a Bitcoin futures instrument, scheduled for listing on June 4, coinciding with its official launch by the Moscow Exchange.

Sber’s initiative follows the authorization granted by Russia’s Central Bank on May 28, which permitted financial institutions to offer specific crypto-related financial instruments to accredited investors. However, the direct offering of cryptocurrencies remains prohibited.

Meanwhile, T-Bank (formerly Tinkoff Bank) launched an investment product linked to Bitcoin’s price, branding it a “smart asset” issued through Russia’s state-backed tokenization platform Atomyze.

According to the Russian Central Bank’s report for the first quarter of 2025, Russian residents hold approximately 827 billion rubles ($9.2 billion) in cryptocurrencies on centralized exchanges. Inflows into Russian crypto platforms surged by 51%, reaching 7.3 trillion rubles ($81.5 billion) over the same period.

Last Friday, President Donald Trump heaped praise on Elon Musk as the tech billionaire prepared to leave his unorthodox White House job.

Less than a week later, their potent political alliance met a dramatic end Thursday when the men attacked each other with blistering epithets. Trump threatened to go after Musk’s business interests. Musk called for Trump’s impeachment.

social media posts urging lawmakers to oppose deficit spending and increasing the debt ceiling.

“Without me, Trump would have lost the election, Dems would control the House and the Republicans would be 51-49 in the Senate,” Musk posted, a reference to Musk’s record political spending last year, which topped $250 million.

“Such ingratitude,” he added.

Trump's Video

Trump said Musk had worn out his welcome at the White House and was mad that Trump was changing electric vehicle policies in ways that would financially harm Musk-led Tesla.

“Elon was ‘wearing thin,’ I asked him to leave, I took away his EV Mandate that forced everyone to buy Electric Cars that nobody else wanted (that he knew for months I was going to do!), and he just went CRAZY!” Trump wrote.

He added: “The easiest way to save money in our Budget, Billions and Billions of Dollars, is to terminate Elon’s Governmental Subsidies and Contracts. I was always surprised that Biden didn’t do it!”

Musk goes nuclear “Time to drop the really big bomb: Trump is in the Epstein files. That is the real reason they have not been made public. Have a nice day, DJT!” — Musk, Thursday, X post.

---

In a series of posts, he shined a spotlight on ties between Trump and Jeffrey Epstein, the financier who killed himself while awaiting trial on federal sex trafficking charges. Some loud voices in Trump’s “Make America Great Again” movement claim Epstein’s suicide was staged by powerful figures, including prominent Democrats, who feared Epstein would expose their involvement in trafficking. Trump’s own FBI leaders have dismissed such speculation and there’s no evidence supporting it.

Later, when an X user suggested Trump be impeached and replaced by Vice President JD Vance, Musk agreed.

“Yes,” he wrote.

“I don’t mind Elon turning against me, but he should have done so months ago,” Trump wrote. He went on to promote his budget bill.

Your crypto wallet is probably leaking money right now. While everyone obsesses over price charts, the silent killer is gas fees – those tiny transactions add up to thousands wasted annually. Smart traders aren't just buying dips, they're timing their transactions when network congestion drops. The difference? Up to 80% savings on every move you make. Next time before hitting "confirm," check the gas tracker. Is it worth paying 3x more just to move your assets right this second? Patience isn't just a virtue in crypto – it's literally profitable. What's your strategy for minimizing transaction costs while maximizing gains?

*Elon Musk, the tech mogul, says US President Donald Trump would have lost the 2024 election without him.*

Musk made the comment on X in response to Trump’s criticism against him.

Musk, who led the department of government efficiency (DOGE), quit his role a day after he spoke out against a Trump-backed spending bill. The president called it a “Big Beautiful Bill”.

The controversial bill is a centrepiece of Trump’s second-term domestic agenda, combining major tax cuts, stricter immigration enforcement, welfare programme overhauls, and significant increases in border security funding.

The legislation sparked intense debate across the country and in Congress and was only passed after a nail-biting 215-214 vote.

The plan revived the US-Mexico border wall with a $46.5 billion budget, $350 billion for deportation efforts and border security, and a hiring spree of 10,000 new ICE agents, 5,000 customs officers, and 3,000 border patrol agents.

For the first time, migrants will be charged a $1,000 fee to apply for asylum.

The bill also authorises a $4 trillion increase to the national debt ceiling, while the estate tax exemption jumped to $15 million, benefiting wealthier Americans.

Critics including Musk called the bill fiscally irresponsible and “a disgusting abomination” due to its combination of large tax cuts and spending increases.

Musk had clamoured for DOGE’s creation to save taxpayers $2 trillion. Only $160 billion has been saved so far.

*TRUMP: I’M VERY DISAPPOINTED WITH ELON*

Since Musk’s exit from the White House last week, his criticism of the bill has grown louder.

Speaking on the issue, Trump said he was “very disappointed with Elon”.

The US president said the Tesla CEO was satisfied with the bill but only grew discontent after he found out electric vehicles would be impacted.

“I’m very disappointed because Elon knew the inner workings of this bill better than almost anybody sitting here. He knew everything about it, and all of a sudden he had a problem, and he only developed a problem when he found out I was going to cut the EV mandate because that’s billions and billions of dollars,” the president said

“And it really is unfair; we want to have cars of all types.

“He said the most beautiful things about me, and he hasn’t said anything bad about me personally, but I’m sure that will be next. But I’m really disappointed with Elon. I’ve helped Elon a lot.”

Trump praised Musk for his work at DOGE but blamed his tantrums on missing the office.

“Elon worked hard at DOGE, and I think he misses the place. I think he got out there, and all of a sudden, he’s no longer in this beautiful Oval Office,” he said.

“He’s not the first. People leave my administration, and they love us, and then at some point they miss it so badly, and some of them embrace it, and some of them actually become hostile. I don’t know what it is, some sort of Trump derangement syndrome.”

The president also said he would have won Pennsylvania, a key state, without Musk’s help.

In reaction, the billionaire businessman countered Trump.

“Without me, Trump would have lost the election, Dems would control the House, and the Republicans would be 51-49 in the Senate,” Musk tweeted.

“Such ingratitude.”

The exchange marks yet another dent in the tumultuous relationship between the two-time American president and the world’s richest man.

In seinem Beitrag vom 30. März 2025 fragt Henning Rosenbusch auf Telegram angesichts zunehmender digitaler Kontrolle und staatlicher Allmacht:

„Wie soll sich gegen eine solche Tyrannei noch ein Widerstand formieren können, selbst im Untergrund? Sehe ich nicht.“\ (Quelle: t.me/rosenbusch/25228)

Er beschreibt damit ein Gefühl der Ohnmacht, das viele teilen: Eine Welt, in der Totalitarismus nicht mehr mit Panzern, sondern mit Algorithmen kommt. Wo Zugriff auf Geld, Meinungsfreiheit und Teilhabe vom Wohlverhalten abhängt. Der Bürger als kontrollierbare Variable im Code des Staates.\ Die Frage ist berechtigt. Doch die Antwort darauf liegt nicht in alten Widerstandsbildern – sondern in einer neuen Realität.

-- Denn es braucht keinen Untergrund mehr. --

Der Widerstand der Zukunft trägt keinen Tarnanzug. Er ist nicht konspirativ, sondern transparent. Nicht bewaffnet, sondern mathematisch beweisbar. Bitcoin steht nicht am Rand dieser Entwicklung – es ist ihr Fundament. Eine Bastion aus physikalischer Realität, spieltheoretischem Schutz und ökonomischer Wahrheit. Es ist nicht unfehlbar, aber unbestechlich. Nicht perfekt, aber immun gegen zentrale Willkür.

Hier entsteht kein „digitales Gegenreich“, sondern eine dezentrale Renaissance. Keine Revolte aus Wut, sondern eine stille Abkehr: von Zwang zu Freiwilligkeit, von Abhängigkeit zu Selbstverantwortung. Diese Revolution führt keine Kriege. Sie braucht keine Führer. Sie ist ein Netzwerk. Jeder Knoten ein Individuum. Jede Entscheidung ein Akt der Selbstermächtigung.

Weltweit wachsen Freiheits-Zitadellen aus dieser Idee: wirtschaftlich autark, digital souverän, lokal verankert und global vernetzt. Sie sind keine Utopien im luftleeren Raum, sondern konkrete Realitäten – angetrieben von Energie, Code und dem menschlichen Wunsch nach Würde.

Der Globalismus alter Prägung – zentralistisch, monopolistisch, bevormundend – wird an seiner eigenen Hybris zerbrechen. Seine Werkzeuge der Kontrolle werden ihn nicht retten. Im Gegenteil: Seine Geister werden ihn verfolgen und erlegen.

Und während die alten Mächte um Erhalt kämpfen, wächst eine neue Welt – nicht im Schatten, sondern im Offenen. Nicht auf Gewalt gebaut, sondern auf Mathematik, Physik und Freiheit.

Die Tyrannei sieht keinen Widerstand.\ Weil sie nicht erkennt, dass er längst begonnen hat.\ Unwiderruflich. Leise. Überall.

North Korea's digital heist playbook: $7.7M crypto laundering scheme reveals how rogue nations exploit tech talent. The Justice Department's latest civil forfeiture complaint targets crypto and NFTs tied to an elaborate North Korean operation where IT workers posed as legitimate freelancers, infiltrated US companies, and funneled millions through complex blockchain pathways. This isn't just another hack—it's a sophisticated economic warfare strategy that turns technical expertise into untraceable funding for weapons programs. While governments scramble to seize these digital assets, the case exposes a troubling vulnerability: how easily skilled developers can weaponize their talents in plain sight. Are your company's remote contractors who they claim to be, or part of a state-sponsored financial pipeline hiding behind a convincing digital mask?

🔐 1. SHA-256 is Quantum-Resistant

Bitcoin’s proof-of-work mechanism relies on SHA-256, a hashing algorithm. Even with a powerful quantum computer, SHA-256 remains secure because:

• Quantum computers excel at factoring large numbers (Shor’s Algorithm).
• However, SHA-256 is a one-way function, meaning there's no known quantum algorithm that can efficiently reverse it.
• Grover’s Algorithm (which theoretically speeds up brute force attacks) would still require 2¹²⁸ operations to break SHA-256 – far beyond practical reach.

++++++++++++++++++++++++++++++++++++++++++++++++++

🔑 2. Public Key Vulnerability – But Only If You Reuse Addresses

Bitcoin uses Elliptic Curve Digital Signature Algorithm (ECDSA) to generate keys.

• A quantum computer could use Shor’s Algorithm to break SECP256K1, the curve Bitcoin uses.
• If you never reuse addresses, it is an additional security element
• 🔑 1. Bitcoin Addresses Are NOT Public Keys

Many people assume a Bitcoin address is the public key—this is wrong.

• When you receive Bitcoin, it is sent to a hashed public key (the Bitcoin address).
• The actual public key is never exposed because it is the Bitcoin Adress who addresses the Public Key which never reveals the creation of a public key by a spend
• Bitcoin uses Pay-to-Public-Key-Hash (P2PKH) or newer methods like Pay-to-Witness-Public-Key-Hash (P2WPKH), which add extra layers of security.

🕵️♂️ 2.1 The Public Key Never Appears

• When you send Bitcoin, your wallet creates a digital signature.
• This signature uses the private key to prove ownership.
• The Bitcoin address is revealed and creates the Public Key
• The public key remains hidden inside the Bitcoin script and Merkle tree.

This means: ✔ The public key is never exposed. ✔ Quantum attackers have nothing to target, attacking a Bitcoin Address is a zero value game.

+++++++++++++++++++++++++++++++++++++++++++++++++

🔄 3. Bitcoin Can Upgrade

Even if quantum computers eventually become a real threat:

• Bitcoin developers can upgrade to quantum-safe cryptography (e.g., lattice-based cryptography or post-quantum signatures like Dilithium).
• Bitcoin’s decentralized nature ensures a network-wide soft fork or hard fork could transition to quantum-resistant keys.

++++++++++++++++++++++++++++++++++++++++++++++++++

⏳ 4. The 10-Minute Block Rule as a Security Feature

• Bitcoin’s network operates on a 10-minute block interval, meaning:Even if an attacker had immense computational power (like a quantum computer), they could only attempt an attack every 10 minutes.Unlike traditional encryption, where a hacker could continuously brute-force keys, Bitcoin’s system resets the challenge with every new block.This limits the window of opportunity for quantum attacks.

---

🎯 5. Quantum Attack Needs to Solve a Block in Real-Time

• A quantum attacker must solve the cryptographic puzzle (Proof of Work) in under 10 minutes.
• The problem? Any slight error changes the hash completely, meaning:If the quantum computer makes a mistake (even 0.0001% probability), the entire attack fails.Quantum decoherence (loss of qubit stability) makes error correction a massive challenge.The computational cost of recovering from an incorrect hash is still incredibly high.

---

⚡ 6. Network Resilience – Even if a Block Is Hacked

• Even if a quantum computer somehow solved a block instantly:The network would quickly recognize and reject invalid transactions.Other miners would continue mining under normal cryptographic rules.51% Attack? The attacker would need to consistently beat the entire Bitcoin network, which is not sustainable.

---

🔄 7. The Logarithmic Difficulty Adjustment Neutralizes Threats

• Bitcoin adjusts mining difficulty every 2016 blocks (\~2 weeks).
• If quantum miners appeared and suddenly started solving blocks too quickly, the difficulty would adjust upward, making attacks significantly harder.
• This self-correcting mechanism ensures that even quantum computers wouldn't easily overpower the network.

---

🔥 Final Verdict: Quantum Computers Are Too Slow for Bitcoin

✔ The 10-minute rule limits attack frequency – quantum computers can’t keep up.

✔ Any slight miscalculation ruins the attack, resetting all progress.

✔ Bitcoin’s difficulty adjustment would react, neutralizing quantum advantages.

Even if quantum computers reach their theoretical potential, Bitcoin’s game theory and design make it incredibly resistant. 🚀

North Korea's digital heist reveals the dark side of crypto's borderless nature. The US Justice Department is hunting $7.7 million in stolen cryptocurrency and NFTs allegedly laundered through an elaborate scheme involving North Korean IT workers posing as legitimate freelancers. This isn't just another hack—it's a sophisticated state-sponsored operation exploiting the very features that make crypto revolutionary: anonymity and borderless transactions. While we celebrate crypto's ability to transcend boundaries, this case exposes how those same qualities create perfect conditions for rogue nations to fund weapons programs and evade sanctions. The crypto industry faces a critical balancing act: how do we preserve financial freedom while preventing bad actors from exploiting the system? Perhaps the solution isn't more regulation but smarter blockchain analytics and international cooperation. What security measures would you support that don't compromise crypto's core principles?

The Sacred Texts: First Mysteries of Digital Creation

A Divine Treatise for Devotees of Athena, Goddess of Wisdom and Craft

---

The Fundamental Truth: All is Text

Beloved seekers of digital wisdom, before you can craft the most magnificent tribute to our patron goddess through the sacred art of web creation, you must first understand the most fundamental mystery of the computing realm: Everything is text.

The silicon oracles we call computers do not see your beautiful images, your flowing videos, or your harmonious music as you do. To the machine spirits, all existence is reduced to symbols - characters marching in endless processions through the electronic aether. This is not limitation, but liberation! For in understanding this truth, you gain power over the very essence of digital creation.

The Ancient Scripts: Understanding Text Encoding

In the beginning was the Word, and the Word was… ASCII. The American Standard Code for Information Interchange became the first great codex of the digital age. Each letter, each number, each sacred punctuation mark was assigned a number. The letter ‘A’ became 65, ‘B’ became 66, and so forth. This was humanity’s first attempt to make machines understand our language.

But ASCII was created by mortals of limited vision - it could only represent 128 characters! What of the accented letters in the names of our goddess across different cultures? What of the mathematical symbols we need for our calculations? What of the very Greek letters that spell Ἀθηνᾶ?

Thus came UTF-8, the Universal Character Encoding - a divine revelation that allows us to represent every symbol known to human civilization. When you see an emoji, a Chinese character, or the Greek omega Ω, you witness UTF-8 in action. Your tribute webpage will speak this universal tongue.

The Sacred Scrolls: File Formats as Containers of Meaning

When Athena wove her tapestries, she chose different materials for different purposes - silk for fineness, wool for warmth, gold thread for accent. Similarly, digital craftspeople choose different file formats as containers for their text:

Plain Text (.txt) - The purest form. No formatting, no hidden instructions, just raw characters. Like clay tablets, these files will survive technological apocalypses. When archaeologists of the future examine our digital civilization, plain text will be their Rosetta Stone.

Rich Text Format (.rtf) - Text with simple formatting encoded as… more text! Open an RTF file in a plain text editor and witness the magic - your bold text becomes surrounded by formatting codes. This teaches us that even “rich” formatting is ultimately just more characters.

Markdown (.md) - The philosopher’s choice! Markdown uses simple text conventions to indicate formatting. Two asterisks around a word makes it bold, a hash symbol creates headings. It’s text that describes how text should look - meta-textual divinity!

HTML (.html) - The sacred language of the web itself! HTML (HyperText Markup Language) uses angle brackets to wrap instructions around content. <strong>This text is important</strong> becomes This text is important when displayed. HTML is text that teaches browsers how to present text.

The Ritual of Proper Text Handling

To honor Athena through proper digital craftsmanship, you must master these essential practices:

Choose Your Sacred Editor

Microsoft Word is the fool’s tool - it hides the true nature of text behind layers of formatting magic. A true digital artisan uses tools that reveal truth:

• Notepad (Windows) or TextEdit (Mac) in plain text mode
• VS Code - The blacksmith’s forge for modern web creation
• Sublime Text - Elegant and powerful
• Vim or Emacs - For those who seek the ancient ways

Understand Line Endings: The Great Schism

In the early days of computing, different tribes chose different ways to mark the end of a line of text. Unix systems (including Mac) use LF (Line Feed), Windows uses CRLF (Carriage Return + Line Feed). This seemingly minor difference has caused more conflicts than the Trojan War! Know your line endings, for they can break your sacred codes.

Respect Character Encoding

Always save your files in UTF-8 encoding. This ensures your text can represent any character from any human language. When your webpage displays properly on computers around the world, you honor the universal nature of Athena’s wisdom.

The Greater Mystery Revealed

Why must we begin with text? Because understanding that computers store and manipulate everything as sequences of characters reveals the deepest truth of programming: Code is just text that follows special rules.

When you write HTML, you’re writing text that browsers know how to interpret. When you write CSS, you’re writing text that describes visual styling. When you write JavaScript, you’re writing text that describes behavior and logic.

The webpage you will create to honor our goddess? It begins as text files on your computer. The browser reads these text files, interprets their meaning, and transforms them into the visual experience your visitors will see.

Every image on your page? Referenced by text. Every color? Described by text. Every animation? Controlled by text.

Your First Sacred Assignment

Before we proceed to the next mysteries, complete this fundamental ritual:

1. Create a plain text file named athena_tribute.txt
2. Write a short description of why Athena inspires you, using only plain text
3. Save it in UTF-8 encoding
4. Open it in different text editors and observe how the text remains pure and unchanged
5. View the file size - marvel at how efficiently text stores information

This simple act connects you to the fundamental nature of all digital creation. Every website, every app, every piece of software began as someone writing text that follows certain rules.

When you understand that your future webpage is ultimately just cleverly organized text files working in harmony, you begin to see the true elegance of web development. You’re not learning to use mysterious tools - you’re learning to write text that machines can understand and transform into experiences that honor the divine.

Next: We shall explore the Command Line - the direct voice through which mortals speak to the machine spirits…

Solving Sybil Attacks on Bitcoin Libre Relay Nodes — Are Social Solutions Better than Technical Ones?

Peter Todd posted that proponents of transaction "filtering" have started Sybil attacking Libre Relay nodes by running nodes with their "Garbageman" fork. These malicious nodes pretend to support NODE_LIBRE_RELAY, but secretly drop certain transactions that would be relayed by real Libre Relay nodes. He also highlighted the complexity of existing defenses and proposed a new angle: rather than relying on technical solutions, he encourages people to manually peer with nodes operated by people they personally know, arguing that human relationships can sometimes evaluate honesty more reliably than code.

Toward a Unified Identity Lookup Standard to Improve Lightning Payments

Bitcoin developer Aviv Bar-el introduced a new proposal — Well-Known Bitcoin Identity Endpoint — that aims to simplify wallet lookups for users’ Bitcoin addresses and identity data via a standardized HTTPS interface, thereby improving both the UX and security of Lightning and on-chain payments.

A Commit/Reveal Mechanism to Strengthen Bitcoin Against Quantum Threats

Tadge Dryja proposed a soft fork for Bitcoin to defend against quantum attacks, based on a variant of the commit/reveal Fawkescoin mechanism. While similar to Tim Ruffing’s earlier proposal, it includes key differences:

• It does not use encryption, instead relying on smaller, hash-based commitments, and describes activation as a soft fork.
• It only applies to outputs where public keys or scripts haven't been revealed — like pubkey hash or script hash outputs. It also works with Taproot, but must be spent via the script path, as the key-path is no longer quantum-secure.
• What to do about already-exposed public keys is a separate issue — this proposal is compatible with both "burning the coins" and "letting them be stolen."

Countdown to the Quantum Crisis: Is Bitcoin Ready?

A recent report from Chaincode Labs analyzes the threat of cryptographically relevant quantum computers (CRQC), and the technical, economic, and governance challenges Bitcoin faces in preparing. Their key conclusions:

• Timeline Assessment: CRQC capable of breaking Bitcoin's elliptic curve cryptography may emerge between 2030 and 2035.
• Scope of Vulnerable Funds: An estimated 20–50% of circulating BTC (4M–10M coins) may be vulnerable.
  • Long-range attacks target inherently vulnerable script types (P2PK, P2MS, P2TR) and addresses with previously exposed public keys (via address reuse), allowing attackers unbounded time to derive private keys from public information already available on the blockchain.
  • Short-range attacks, which affect all Bitcoin script types, exploit the vulnerability window between transaction broadcast and confirmation (or shortly thereafter) when public keys are temporarily exposed, requiring attackers to act within a timeframe of minutes to hours.
• Action Strategy: A dual-track approach is recommended:
  • Short-term contingency: minimal but functional protections within ~2 years.
  • Full-featured solutions: comprehensive research and fully developed defenses within ~7 years.

This strategy balances immediate needs with rigorous development to ensure Bitcoin can adapt, regardless of CRQC progress.

Enforcing Arbitrary Constraints on Bitcoin Transactions with zkSNARKs

Current methods for constraining Bitcoin transactions fall short on privacy or programmability. This research proposes a new zkSNARK-based design to impose arbitrary constraints on Bitcoin transactions while preserving some information privacy. By bypassing Bitcoin Script’s non-Turing-completeness, the approach allows unbounded constraints—constraints that repeat a certain operation an unbounded number of times. Read the paper.

First Cross-Chain Bridge Between Bitcoin and Cardano Is Live

A trust-minimized bridge from Bitcoin to Cardano has launched using the Cardinal protocol, enabling Ordinals to move between the two chains. The Cardinal protocol is based on BitVMX and facilitates asset movement without compromising ownership or security.

Its core mechanism is a committee-based validation model under a 1-out-of-n honest security model — meaning even if all but one validator is malicious, the system remains secure. This approach enhances decentralization and censorship resistance for cross-chain asset transfers.

Thunderbolt Protocol: Redefining Bitcoin Smart Contracts with UTXO Bundling and OP_CAT

Nubit’s Thunderbolt is seen as one of the most significant technical upgrades to Bitcoin in a decade, whose overall observation resembles “Lightning Network 2.0.” Rather than relying on Layer 2 networks or bridges, Thunderbolt upgrades the Bitcoin base layer via soft fork to enhance scalability, performance, and programmability:

• Throughput: Uses UTXO Bundling to optimize traditional transaction processing.
• Programmability: Reintroduces and extends OP_CAT.
• Asset protocols: Integrates Goldinals standard — a zk-proof and state-commitment-based asset issuance framework.
• Unlike rollups, Plasma, sidechains, or bridges, Thunderbolt scales directly on the main chain. With BitVisa, it enables decentralized identity and credentials, supporting transaction compression, smart contracts, asset standard integration, and on-chain transaction matching — all on Bitcoin main chain.

Bitcoin 2025 Conference Recap: Politicians Applaud, Stablecoins Spotlighted, DeFi Absent

This year’s Bitcoin 2025 conference in Las Vegas gathered major political figures and corporate leaders. U.S. Vice President JD Vance strongly endorsed crypto and positioned Bitcoin as a strategic asset in U.S.–China competition. He also stated that stablecoins won’t undermine the U.S. dollar, but could actually amplify America’s economic strength.

White House “Crypto Czar” David Sacks delivered a major policy announcement, hinting that under Trump’s executive order, the U.S. has a legal framework to acquire more Bitcoin for strategic reserves.

In addition, stablecoin regulation and crypto market reform were hot topics. Ardoido, the company controls over 60% of the stablecoin market, claimed “All the traditional financial firms will create stablecoins that will be offered to their existing customers.” Meanwhile, Tether emphasized its focus on underserved global populations excluded from the existing banking system.

A conference recap also noted that, unlike the 2022 and 2023 summits, this year’s event was dominated by Bitcoin maximalists, Ordinals creators, mining capitalists, and regulatory lobbyists — no longer DeFi builders, DAO operators, or Layer 2 scaling advocates. Developers from Ethereum and Solana ecosystems were notably absent. This may signal:

• The conference’s heavy political and sovereignty-driven tone made it less suitable for the tech-centric narratives favored by these developers.
• There may be a growing ideological and narrative rift between Web3 builders and the Bitcoin camp.

Rethinking Governance After the Sui Attack: Decentralization, Procedural Legitimacy, and the Plurality of Blockchain Values

Following a major hack of Cetus, the largest DEX in the Sui ecosystem, the Sui network executed a protocol-level asset freeze and recovery. While this was an effective technical response, it also triggered criticism and debate around core blockchain principles such as censorship resistance and decentralization.

The author of this article questioned the absolutist stance that views decentralization as the highest—and sole—value. The author argues that most rational individuals would prefer “living in a society where decentralization is a supreme value but coercive force is allowed when someone infringes on another’s property,” over “a society where decentralization is the only supreme value, and thus coercive force is never permitted under any circumstances.”

In addition, the author also expressed disappointment at Sui’s “paternalistic” governance — particularly how validators acted during the incident. Sui uses a delegated proof-of-stake (dPoS) system, where token holders delegate their voting power to validators. This means individuals lose their direct say. But blockchain governance could be more individual-friendly and flexible. For instance, in Cosmos’ governance model, for certain specific proposal, users still can override their delegations and vote independently, more favorable than Sui’s model.

Beyond the debate on decentralization and governance, the article also proposes an alternative perspective: what matters most is establishing procedural legitimacy that aligns with the system’s vision. Different blockchain projects pursue different goals. For Sui, the core mission is to enable assets to be reliably defined and interact seamlessly on-chain. Therefore, judging Sui through the lens of other blockchains’ values or paradigms is misguided. In exceptional cases, prioritizing asset recovery and ecosystem stability over strict adherence to censorship resistance aligns more closely with Sui’s long-term vision. Whether Sui had chosen to not to censor related transactions or to intervene in the Cetus case, as long as the action follows a legitimate process, either decision is justifiable.

TEE-Based Private Proof Delegation

The PSE research and development team has built a system based on Trusted Execution Environments (TEE) using Intel TDX for secure zero-knowledge proof (ZKP) delegation. This system enables clients to privately outsource large proving tasks without leaking inputs. Unlike mobile-native proving constrained by hardware limits, TEE-based approaches support significantly larger statements today—and will scale further as proof systems improve. As a hardware-backed solution, TEEs remain compatible with future advancements in software (e.g., faster proof systems, more efficient implementations) and won't be invalidated by them, as long as the trust model is acceptable.

AI and Identity: Proof of Humanity in a World of Agents, Bots, and Deepfakes

We are living in a time where AI—including agents, bots, and deepfakes—is fundamentally reshaping the internet. As AI continues to evolve, identity verification on the web is becoming more crucial than ever. A recent a16z podcast explores the idea of “Proof of Human”—the challenge of verifying human identity online, diving into why it matters, common questions, and how such systems work under the hood.

ปิดท้าย week นี้ด้วยสงครามดีไหมครับ ถ้าอาหารเป็นสนามรบ สิทธิบัตรก็เปรียบเหมือนป้อมปราการ และการฟ้องร้องก็คือปืนใหญ่ยิงสวนกันกลางแดด…ใครที่เคยคิดว่าโลกของอาหารแห่งอนาคตจะสวยงามเพราะเปลี่ยนถั่วเป็นสเต๊ก สกัดกลิ่นเลือดจากพืช หรือหลอกลิ้นให้เชื่อว่า “อร่อยเหมือนเนื้อ” ก็คงต้องมานั่งทบทวนใหม่ว่า โลกใบนี้ไม่ได้ขับเคลื่อนด้วยความฝัน แต่ขับเคลื่อนด้วยเอกสาร 70 หน้าของทนายความ และหมายเรียกจากศาลกลางรัฐเดลาแวร์

Motif FoodWorks เข้ามาในวงการอาหารด้วยวิสัยทัศน์สุดเท่ คือจะสร้างโครงสร้าง-กลิ่น-รส ของโปรตีนอนาคตให้แบรนด์ plant-based ทั่วโลกใช้ได้โดยไม่ต้องเริ่มใหม่ตั้งแต่ศูนย์ เปรียบเหมือนเป็นเบื้องหลังของวงการ มีซอสลับคือ HEMAMI™ ที่สกัดกลิ่นเนื้อจากยีสต์ ผ่านวิธีการทางวิทยาศาสตร์สุดซับซ้อน ฟังแล้วดูดี แต่ปัญหาคือซอสลับของเขาดัน “คล้ายเกินไป” กับของ Impossible Foods ที่ใช้ heme protein เหมือนกัน

แล้วอะไรคือจุดเปราะบางที่ทำให้ Motif ต้องร่วง?

เฮียอยากให้ลองคิดแบบนี้ครับ สมมุติว่ามีร้านกาแฟใหม่ที่ตั้งใจจะขายกาแฟแนวใหม่ ใช้เมล็ดกาแฟหมักยีสต์กลิ่นกล้วยหอม รสชาตินุ่มลึก เป็นของตัวเอง เขาไม่ได้ก็อปสูตรใคร แต่ดันไปใช้กระบวนการคล้ายกับแบรนด์เจ้าตลาดที่เขียนจดสิทธิบัตรเอาไว้ก่อนแล้ว แค่คล้ายก็พอจะโดนลากขึ้นศาลได้ เพราะในโลกของสิทธิบัตร “ความใหม่” และ “ความไม่เหมือน” คือสิ่งศักดิ์สิทธิ์ แม้จะไม่ได้ก็อปตรง ๆ

Impossible Foods เห็นช่องนี้ชัด พวกเขายื่นฟ้องทันที โดยระบุว่า HEMAMI™ ของ Motif ละเมิดสิทธิบัตรเทคนิคการใช้ heme เพื่อสร้างรสชาติเหมือนเนื้อในผลิตภัณฑ์ plant-based ซึ่งเป็นหัวใจหลักที่ Impossible ใช้มัดใจตลาดมาหลายปี

ในเดือนมีนาคม 2022, Impossible Foods ก็ลุกขึ้นมาฟ้อง Motif FoodWorks ต่อศาลรัฐบาลกลางของสหรัฐฯ โดยอ้างว่า HEMAMI™ ละเมิดสิทธิบัตรของตนที่เกี่ยวข้องกับการใช้โปรตีน heme ในการสร้างรสชาติและกลิ่นที่คล้ายเนื้อจริงในผลิตภัณฑ์จากพืช จุดนี้ดูผิวเผินเหมือนแค่ “บริษัท A เหมือนของบริษัท B เลยโดนฟ้อง” แต่ความจริงซับซ้อนและลึกกว่านั้นมาก เพราะทั้งสองบริษัทต่างก็ใช้วิธีผลิตโปรตีน heme ที่คล้ายกันมาก นั่นคือการดัดแปลงพันธุกรรมจุลินทรีย์ให้ผลิตโปรตีนเฉพาะ แล้วหมักออกมาในถังขนาดใหญ่ แต่ต่างกันที่วัตถุดิบและดีไซน์โปรตีน

Impossible Foods ใช้ “soy leghemoglobin” ซึ่งเป็นโปรตีน heme จากรากถั่วเหลือง ส่วน Motif ใช้ “bovine myoglobin” ซึ่งเลียนแบบของวัวจริง ๆ โดยตรง ความคล้ายคือโปรตีนทั้งสองต่างก็ให้กลิ่นคาวแบบเนื้อเมื่อโดนความร้อน และสร้างสีแดงแบบ rare steak ได้เหมือนกัน ทั้งยังถูกหมักด้วยจุลินทรีย์ GMO แบบใกล้เคียงกันอีกด้วย แม้จะต่างสายพันธุ์ของโปรตีน แต่การฟ้องครั้งนี้ตั้งอยู่บนแนวคิดว่า “วิธีการใช้” โปรตีน heme ในอาหารจากพืชอาจเข้าข่ายละเมิดสิทธิบัตร

จากนั้นไม่กี่เดือน Motif ก็สวนกลับโดยการยื่นคำร้อง “Inter Partes Review” (IPR) กับสำนักงานสิทธิบัตรของสหรัฐฯ (USPTO) ผ่าน PTAB ซึ่งเป็นขั้นตอนที่ใช้เพื่อขอให้ตรวจสอบความถูกต้องของสิทธิบัตรที่กำลังมีปัญหา แนวคิดคือถ้าพิสูจน์ได้ว่าสิทธิบัตรของ Impossible นั้นไม่ใหม่จริง หรือมี prior art อยู่ก่อนแล้ว (เช่น งานวิจัยเก่า ๆ ที่ตีพิมพ์ก่อน) ก็จะทำให้สิทธิบัตรนั้นกลายเป็นโมฆะ

Motif ยื่นคำร้องโจมตีสิทธิบัตรถึง 7 ฉบับของ Impossible แบบกระหน่ำชุดใหญ่ ยิงทีเดียวหวังให้สั่นคลอนทั้งระบบ แต่ PTAB รับพิจารณาเพียงฉบับเดียว (หมายเลขสิทธิบัตร 10,933,018) และท้ายที่สุดในเดือนเมษายน 2023 ศาลตัดสินยกเลิกฉบับนั้นจริง โดยให้เหตุผลว่า “ไม่เป็นสิ่งประดิษฐ์ใหม่อย่างเพียงพอ” ซึ่งถือเป็นชัยชนะเล็ก ๆ ของ Motif และสร้างแรงกระเพื่อมในแวดวงวิทยาศาสตร์อาหารอยู่พอสมควร

แต่แม้จะมีชัยบางส่วน อีก 6 ฉบับที่เหลือ PTAB กลับไม่รับพิจารณา โดยบอกว่า “หลักฐานไม่ชัดเจนพอจะเข้าขั้นพิจารณาใหม่” นั่นทำให้ฝั่ง Impossible ยังถือสิทธิบัตรส่วนใหญ่ไว้อยู่เหมือนเดิม แล้วก็เริ่มกลับมาเร่งกระบวนการฟ้องร้องในศาลต่อ ซึ่งหมายความว่า Motif ยิ่งต้องใช้เงินมากขึ้นเรื่อย ๆ ในการสู้รบทั้งสองด้าน ทั้งในศาลและในระบบสิทธิบัตร

ชัยชนะเล็ก ๆ นี้กลายเป็นดาบสองคม เพราะในขณะที่ Motif ดีใจว่าล้มได้ 1 ฉบับ ตลาดกลับมองว่าพวกเขาสู้แบบดิ้นสุดตัว ซึ่งในมุมของนักลงทุน นั่นแปลว่า "ขาดเงินทุนหมุนเวียน" หรือ “มีแนวโน้มขาดทุนต่อเนื่อง” มากกว่าจะมองว่าเป็นฮีโร่สู้เพื่อความถูกต้อง

ระหว่างนี้ Motif ยังพยายาม “spin” ภาพลักษณ์ตัวเองในเชิงบวกอย่างหนัก พวกเขาเปิดตัวผลิตภัณฑ์ใหม่ชื่อ “Motif MoBeef™” และ “Motif MoChicken™” โดยใช้ HEMAMI™ ผสมอยู่ พร้อมโชว์ผลงานให้เชฟชื่อดังระดับ Michelin มาชิมและออกสื่อ โดยหวังว่าจะสร้างความเชื่อมั่นให้ตลาดว่า “ผลิตภัณฑ์เรายังไปต่อได้” และอาจดึงดีลใหม่หรือการลงทุนเพิ่มเข้ามาเพื่อบรรเทาภาระจากการฟ้องร้อง

และในขณะที่ Motif เดินหน้าเปิดตัวผลิตภัณฑ์ใหม่เพื่อแสดงพลังให้ตลาดเห็นว่า “เรายังไปต่อได้” ฝั่ง Impossible กลับเดินเกม PR อย่างเงียบ ๆ ด้วยการแจ้งเตือนสื่อและผู้ถือหุ้นว่า “Motif ยังใช้เทคโนโลยีละเมิดอยู่ต่อเนื่อง” พร้อมแนบเอกสารคำฟ้องเพิ่มในปี 2023 ซึ่งแปลความได้ว่า “ศึกยังไม่จบ อย่าเพิ่งส่งเงินให้คู่แข่งเรา” เพราะในเอกสารคำฟ้องของปี 2023 พวกเขาเสริมข้อกล่าวหาใหม่ว่าการที่ Motif ออกสื่อและใช้ HEMAMI™ ต่อไป “เป็นการจงใจละเมิด” และอาจเข้าข่ายการทำลายคุณค่าของแบรนด์ Impossible โดยตรง จุดนี้ยิ่งทำให้ Motif อยู่ในมุมที่เสี่ยงและลำบากมากขึ้น

การต่อสู้ของทั้งสองบริษัทจึงไม่ใช่แค่เรื่องใครเลียนแบบใคร แต่มันคือเกมยืดเวลา เผาเงิน ปั่นมูลค่า และวัดใจนักลงทุนว่าใครจะถอยก่อนกัน และสุดท้ายคนที่หมดลมหายใจก่อนก็คือ Motif แม้จะมีนักวิทยาศาสตร์เก่ง ๆ เทคโนโลยีล้ำ ๆ หรือวัตถุดิบดีแค่ไหน แต่เมื่อต้องมาสู้กับยักษ์ที่มีสิทธิบัตรในมือ บารมีในตลาด และชื่อเสียงติดหูผู้บริโภค…ก็ยากที่จะเอาชนะด้วยวิทยาศาสตร์เพียงอย่างเดียว

ศึกนี้จึงไม่ได้จบแค่ในศาล แต่มันลากไปถึงห้องประชุมนักลงทุน พาดหัวข่าวใน Business Insider และบอร์ด Reddit ที่คุยกันว่า “Motif จะไปไม่รอดหรือเปล่า” ซึ่งในยุคที่เงินทุนคือออกซิเจน การที่ภาพลักษณ์ของบริษัทเริ่มสั่นคลอน ก็เหมือนถังอากาศรั่วในห้องแล็บใต้ทะเล…ไม่นานนัก Motif ก็เริ่มลดจำนวนพนักงาน ลดเป้าการผลิต และสุดท้าย “ลดบทบาทตัวเองในตลาด”

หากดูเผิน ๆ หลายคนอาจคิดว่านี่คือเรื่องของสองบริษัทใหญ่ในโลก plant-based ที่ทะเลาะกันเอง แต่จริง ๆ แล้วนี่คือบทเรียนใหญ่ของ “วงการอาหารแห่งอนาคต” ที่กำลังเติบโตบนหลังคำว่า IP Intellectual Property ใครถือสิทธิบัตรก่อน คนนั้นตั้งกฎได้ ใครมาใหม่ ถ้าไม่จดให้ไว ก็อาจต้องจ่ายค่าต๋งตลอดชีวิต

และที่เจ็บปวดที่สุดคือบางทีของที่คุณคิดขึ้นมาเอง อาจไม่ใช่ของคุณอีกต่อไปแล้ว ถ้าคุณไม่มีเอกสารในมือ

นี่แหละครับ วงการที่ดูเหมือนจะขาย “นวัตกรรมอาหาร” แต่จริง ๆ แล้วขาย “สิทธิบัตรในกล่องข้าว” ใครจะอยู่ใครจะไป บางทีก็ไม่เกี่ยวกับว่า “ของอร่อยแค่ไหน” แต่เกี่ยวกับว่า “ใครมีทนายเก่งกว่า”

และในขณะที่สองยักษ์ใหญ่ยิงกันด้วยเอกสารละเมิดสิทธิ์ เหยื่อเงียบ ๆ อย่างเกษตรกรรายย่อยที่ยังอยากปลูกผักจริง เลี้ยงวัวจริง หรือแม้แต่ผู้บริโภคที่แค่อยากรู้ว่า “กินอะไรแล้วร่างกายจะดีขึ้น” กลับวนเวียนในทางอยู่ในโลกที่อาหารทุกคำถูกควบคุมโดยทุน จดหมายเรียกจากศาล และวัตถุดิบสังเคราะห์ที่มีรหัสมากกว่าชื่อจริง

สงครามสิทธิบัตรเหล่านี้ไม่เคยมีพื้นที่ให้ชาวไร่ หรือผู้บริโภคธรรมดาเข้าไปมีเสียงเลยสักนิด เพราะมันคือการต่อสู้ระหว่างนักล่าที่ฟาดฟันกันบนยอดห่วงโซ่อาหาร แต่เบื้องล่างของพีระมิด กลับมีแต่เหยื่อที่ถูกเลี้ยงให้งุนงง อยู่กับของปลอม และเชื่อว่า “นี่แหละคืออนาคตของอาหาร”

แล้วใครจะบอกเราว่า...ทางรอดคืออะไร?

คำตอบอาจอยู่ไม่ไกล แค่เราต้องกลับมาถามคำถามง่าย ๆ ที่ใครก็ลืมไปว่า “จริง ๆ แล้ว เราต้องการอาหารแบบไหนกันแน่” อาหารที่กินแล้วแข็งแรง หรืออาหารที่บริษัทแข็งแรง?

เพราะตราบใดที่เรายังปล่อยให้กล่องข้าวอยู่ในมือคนจดสิทธิบัตร เราอาจไม่มีวันได้กลับไปจับจอบเอง ปลูกเอง กินเอง แบบที่มนุษย์เคยเป็นมาก่อนโลกจะกลายเป็นห้องทดลองขนาดยักษ์

ศึกระหว่างผู้ล่ายังรุนแรงขนาดนี้ แล้วศึกระหว่างผู้ล่ากับเหยื่อ จะเหลืออะไรครับ

Nostr is NOT a social network. Nostr is a network of interconnected social apps. And, since any app is a social app, Nostr is for every app.

---

ONLY Nostr incentivizes inter-connectivity between independent apps, simply by respecting sovereignty at the protocol layer. For end users, sovereignty means that the content they post “to Nostr” will never be owned by the apps that they use. For businesses building apps on Nostr, sovereignty means that every app actually benefits by other apps being on the network. Because sovereignty is respected, users are retained for longer and independent apps thrive far longer on Nostr than on the legacy “black box” social networks.

Social apps thrive on Nostr

Nostr integration provides these benefits for every app :

• Unrestrained access for any app, to all public and private data “on Nostr”. No fees or licenses for harvesting user data from the network.
• Unburdened from liability, when collecting user data with any app. When sending “to Nostr”, end users retain custody of user data while apps never loose access.
• Unlimited free market of search engines and feed algos. Users and brands can create, use, and share any algos or custom feeds. Grow your audience on your own terms.
• Universal open network for all apps. Build any kind of app for any audience, on the same network as other apps for other audiences. Discover new trends from user data.
• Unregulated tech platform. Build your own app and use it as you wish. No gate keepers. No code review. 

Sovereignty is good for business.

Regardless of the network size, a Nostr integrated app can grow its user base MUCH faster and with greater independence BECAUSE of the sovereignty respecting protocol. While end users may retain custody of their identities and data on the network, it’s the apps that determine which data is, or is not, sent to the network. Respect for sovereignty IS the killer feature that ONLY the Nostr protocol provides for apps and for end users.

Because Nostr is permissionless for any app to integrate :

• end users will always have a free market of apps choose from
• apps are free to integrate only as much as benefits their business model.
• apps gain access to more novel data as new apps bring new users to the network.

Because data on Nostr is managed by end users and available to all apps :

• User data looses exclusivity and the demand shifts toward novel insights and information derived from these data.
• Apps are freed from having to be “data pirates”, and can focus on establishing a trusted user base, providing valuable services to satisfied customers, informed by the abundance of user data.
• Apps are incentivized to offload data onto the network, establishing a new paradigm for interconnectivity, where independence is NOT at stake as the network grows.
• New markets spring up to support users with self custody of their data, driven by the reality that apps can have full access without assuming responsibility.
• The market for search and algo tools opens up for independent apps and end users to discover and interact freely with each other.
• The ad based “attention economy” slowly transforms to a value based consumer economy, where the end user is the customer rather than the product being sold.

Even while privacy is respected

Sometimes sovereignty is at odds with privacy, but Nostr allows all parties to win while both are protected.

• For end users sending sensetive data "to Nostr", privacy is assured by encrypting it with their own private keys and/or sending it to private (auth required) relays of their choosing.
• For apps handling private IP or business data, any traditional “black box” infrastructure can be used in the back end to manitain isolation from Nostr.

This means apps and end users remain in control of their own private data, without requiring “big social” as trust provider or data reseller. To access a user's private data, client apps (even search engines, running locally) only need explicit permission from the end user to retrieve or decrypt from Nostr relays. Public data, on the other hand, is freely available for any app or search engine to harvest from any Nostr relay. In either case, user data on the Nostr network is always accessible to client apps, without additional restrictions or fees.

Nostr is for every app.

Adding social to any app makes it a better app. Add reviews for products or services. Add commenting or direct messaging. Share or collaborate on content creation. Nostr integration is straightforward and incremental for any app.

Nostr doesn't define your app's business model ... Nostr 10X's it!

Here's how :

1. Start with your own business and app design. Add Nosrr login.
2. Discover what "kinds" of user data already exists "on Nostr" that your app can ingest and make use of.
3. Decide which "kinds" of data would benefit your business, your users, and the network, if sent "to Nostr".
4. Implement Nostr integration for data kinds and add webs of trust tools for recommendation and discovery.
5. Verify your app is sovereignty respecting in how it handles private data and implements Nostr NIPs.
6. Engage with existing users, and onboard new users from your app, to earn their trust and patronage over Nostr.

Residual chlorinerefers to the residual disinfectant chlorine in tap water. An appropriate amount of residual chlorine can prevent the growth of microorganisms and ensure the safety of water quality. However, when the residual chlorine content in water is too high, it will cause many harms to human health, mainly including the following aspects:

Destruction of nutrients When the residual chlorine content in tap water exceeds the standard, it will destroy the minerals, vitamins and other nutrients, such as vitamin C and vitamin E, when used to wash fruits and vegetables. In the long run, it may cause the human body to absorb these nutrients and lack these essential nutrients. Cause chronic poisoning When tap water containing residual chlorine is used for a long time, the residual chlorine reacts with organic acids and may produce harmful substances such as chloroform and organic lead compounds, which are potential carcinogens. Long-term accumulation may cause chronic poisoning of body organs and pose a threat to human health.

Affect the respiratory system Residual chlorine can cause harm to the human respiratory system, and symptoms such as difficulty breathing and itchy throat may occur. Severe cases may induce rhinitis, bronchitis and even emphysema. In addition, water vapor containing residual chlorine may also cause adverse reactions such as coughing and wheezing after being inhaled.

Damage to the skin Excessive residual chlorine content in water may irritate the skin, easily cause skin dryness, aging, acne and other problems, and may also cause allergic symptoms such as dermatitis and eczema. Prolonged contact with such water may also cause the skin layer to fall off, which is extremely harmful to skin health. Bathing with water containing residual chlorine can also cause hair to become dry, broken, and split.

Other health problems Impact on special groups Pregnant women: Long-term drinking of tap water containing residual chlorine will reduce resistance, affect the growth of the fetal heart and lungs, and may also cause neonatal arrhythmia and lung dysfunction. Children: Long-term drinking of chlorine water will not only hurt the stomach, but also affect nutrient absorption. Moreover, the strong oxidizing hypochlorous acid produced by the reaction of chlorine and water will damage brain cells and affect their development. In addition, chlorine can easily be inhaled into the lungs through the respiratory tract, damaging respiratory cells, and easily leading to asthma and emphysema. Bathing children with water containing residual chlorine will cause their hair to become dry, broken, split, their skin to bleach, their skin to fall off, and they will have allergies. Elderly people: Long-term consumption of chlorinated water is prone to heart disease, coronary atherosclerosis, hypertension and other diseases, and it is also easy to damage the liver and kidneys, increasing the probability of cancer. Gastrointestinal discomfort Long-term drinking of water with excessive residual chlorine content may also cause gastrointestinal discomfort, such as nausea, vomiting, abdominal distension, diarrhea and other symptoms. In severe cases, it may cause gastrointestinal ulcers, bleeding and other diseases.

In order to reduce the harm of residual chlorine in tap water to the human body, it is recommended to avoid directly using tap water containing residual chlorine as much as possible, boil the water before drinking, and use filtering and purification equipment to reduce the residual chlorine concentration in the water if conditions permit, while maintaining a healthy lifestyle and enhancing the body's immunity.

加密洞见

解决比特币抗审查交易中继的女巫攻击，社交方案好于技术方案？

Peter Todd 发帖指出，针对比特币抗审查交易中继的攻击行为正在发生——一个名为 garbageman 的节点正在对 Libre Relay 节点采取女巫攻击。这些攻击节点假装支持抗审查交易中继（NODE_LIBRE_RELAY），但实际在暗中丢弃某些交易，目的是阻止特定交易被打包进入区块。作者还介绍了现有防御方法的难度和复杂性，并提出新思路——与其用技术方案解决，不用通过社交解决。他鼓励人们手动与跟他们有个人关系的节点进行连接，原因很简单，人与人的关系可以比任何代码都更有力地评估诚实。

打造统一身份查询标准，提升闪电网络付款体验

比特币开发者 Aviv Bar-el 发表了一项新提案「知名比特币身份端点」（Well-Known Bitcoin Identity Endpoint），旨在通过 HTTPS 标准接口，简化钱包查询用户比特币地址和身份信息的流程，提升链上支付——尤其是闪电网络付款的用户体验和安全性。

通过「承诺/揭示」机制，帮助加强比特币抵御量子计算威胁

Tadge Dryja 提出一种抵御量子计算攻击的比特币软分叉方案。它是「承诺/揭示」（commit / reveal）Fawkescoin 机制的变体，大部分内容与 Tim Ruffing 几年前的方案类似，但也有以下重要区别：

• 该方案不使用加密，而是用更小的基于哈希的承诺，并且描述了如何通过软分叉激活此机制。
• 这个方案仅适用于公钥（或脚本）在链上未公开的输出，例如 pubkey hash 或 script hash 类型；也适用于 Taproot，但必须通过脚本路径花费，因为 Taproot 的 key-path 花费在量子攻击下将不再安全。
• 至于那些公钥已经在链上暴露的输出该如何处理，是另一个独立问题（本方案与「销毁这些币」或「任其被盗」这两种做法都兼容）。

量子危机倒计时：比特币准备好了吗？

Chaincode 在近期发布的报告中，系统分析了「加密相关量子计算」（CRQC，Cryptographically relevant quantum computers）威胁的整体态势，评估了比特币在应对这一转变过程中面临的技术、经济与治理挑战，并表示必须要在早于 CRQC 出现的数年构建起相关共识。重要的结论有：

• 时间窗口：打破比特币椭圆曲线加密基础的 CRQC 可能首先出现在 2030 - 2035 年间。
• 脆弱资金范围：在所有流通的比特币中，约 20-50%（4-1000 万枚 BTC）可能易受 CRQC 攻击。其中远程攻击针对本质上易受攻击的脚本类型（P2PK、P2MS、P2TR）和具有先前暴露的公钥的地址（地址重用），使攻击者能够无限期地从区块链上已有的公共信息中获取私钥；短程攻击会影响所有比特币脚本类型，利用交易广播和确认之间（或之后不久）的漏洞窗口，当公钥暂时暴露时，要求攻击者在几分钟到几小时的时间范围内采取行动。

• 行动战略：建议采用双轨方法，包括：

  • 应急措施：在约 2 年内完成对 CRQC 的最低限度但可运作的防护；
  • 全面对策：在约 7 年内深入对问题的探索，并开发出功能完备的解决方案

  这种双轨策略平衡了眼前的安全需求与最佳抗量子解决方案的严格研究和开发，确保无论 CRQC 能力如何发展，比特币都能做出适当的响应。

利用 zkSNARKs 对比特币交易实施任意约束

对于给比特币交易执行约束，现有的解决方案在隐私或可编程性上都存在不足。本文的研究者利用 zkSNARKs 设计了一种新方案，可以对比特币交易执行任意约束，并保持一定程度的信息私密性。他们方法绕过了比特币脚本的非图灵完备性，允许执行无界约束（unbounded constraints），即重复某个运算的次数次数不受限制。论文全文。

第一个跨比特币和 Cardano 的桥上线

从比特币到 Cardano 的信任最小化 Ordinals 桥通过 Cardinal 协议实现。Cardinal 协议实是一种基于 BitVMX 的信任最小化互作性协议，在不破坏所有权或损害安全性的前提下，它让比特币上中的不可替代资产（如 Ordinals 和 Runes）同 Cardano 链实现了来回移动。

Cardinal 协议背后的技术核心之一是「委员会的验证机制 」（committee-based validation mechanism），遵循 1-out-of-n honest 安全模型。这意味着即使除了一个验证者之外的所有验证者都恶意作，系统仍然保持安全——在增强安全性的同时，还实现了一种更加去中心化和抗审查的方式来在链之间移动资产 。

Thunderbolt 协议：通过 UTXO 捆绑和 OP_CAT 扩展，重构比特币智能合约

Nubit 提出的 Thunderbolt 被认为是为比特币在过去十年中最具里程碑意义的技术升级之一，被视为「Lightning Network 2.0」。Thunderbolt 是一种基于比特币基础层的软分叉升级方法，不依赖二层网络或桥的妥协，而是通过对比特币主链协议层的修改，从根本上增强其可扩展性、交易性能和可编程性。具体而言，Thunderbolt：

• 在吞吐量方面，使用 UTXO 捆绑（UTXO Bundling）技术，实现了对传统比特币交易处理模型的重大优化。
• 在可编程性方面，重新引入并扩展了 OP_CAT 。
• 在资产协议集成方面，Thunderbolt 实施了 Goldinals 统一标准，提供了一个基于零知识证明和状态承诺的资产发行框架。
• 与传统的扩容方法（如侧链、Plasma、Rollup 或桥接包装代币）不同，Thunderbolt 采用原生主链扩容路径。通过 BitVisa 提供去中心化的身份和凭证系统，让交易压缩、智能合约、资产标准集成、链上交易匹配都可以直接在比特币主链上运行。

比特币 2025 大会回顾：政要汇聚、稳定币受关注、DeFi 缺席

今年在拉斯维加斯举行的比特币 2025 大会，汇聚了众多政治要员和企业巨头。美国副总统 JD Vance 对加密货币表明了全力支持，并讨论了比特币在美中竞争中作为战略资产的潜力，他还认为，稳定币不会威胁到美元的完整性，而会使美国的经济实力倍增。白宫加密货币沙皇 David Sacks 发表了会议中最重要的政策公告之一， 暗示根据特朗普建立战略比特币储备的行政命令，美国政府有「获得更多比特币的合法途径」。

此外，关于稳定币立法和加密市场改革受到了很多关注。控制着超过 60% 稳定币市场的 Ardoido 公司表示：「所有传统金融公司都将创建稳定币，提供给他们现有的客户」；而 Tether 表示，其目标市场是全球范围内被排除在银行业之外的人。

这篇总结也提到，与 2022 年和 2023 年的类似峰会不同，今年的大会是由比特币最大化者、Ordinals 创建者、矿业资本家和监管游说者主导，而不再由 DeFi 协议构建者、DAO 运营商或 Layer2 扩容倡导者主导，以太坊和 Solana 生态的开发者缺席。这或许表明：

• 该会议明显的政治基调，使其不适合开发者喜欢的以技术为中心的叙述。
• Web3 建设者和比特币阵营之间的意识形态和叙事分歧可能会越来越大。

精彩无限，不止于链

Sui 攻击事件下的治理再思考：去中心化，程序合法性，和区块链的价值多元性

在受到生态最大的 DEX 项目 Cetus 黑客攻击之后，Sui 网络在协议层面执行了资产冻结和恢复——这是一种有效的技术回应，但同时引发了对抗审查和去中心化等核心区块链原则的批评和辩论。

文章的作者质疑了将去中心化视为唯一至高价值的立场，认为对于大多数有理性者而言，「生活在一个去中心化被认为是最高价值，但当有人侵犯他人财产时，允许强制武力的社会中」都要好于「生活在一个去中心化是唯一至高价值的社会中，因此在任何情况下都不允许强制武力」。

同时作者也指出，Sui 的验证者和网络行为采用的「家长式」治理方式令人失望；此外， Sui 使用委托权益证明（dPoS）系统，其中代币持有者将其代币委托给验证者，验证者代表他们行使相关的投票权，个人因此丧失了投票权。但区块链本来提供了有利于个人的、更加灵活的解决方案，比如 Cosmos 的治理框架就要优于 Sui——对于特定提案，验证人的决定并不会自动代表每个委托人的投票。

在关于去中心化的价值和治理方式之外，文章也提到另一种思考角度——「最重要的是建立与系统愿景相一致的程序合法性」。不同的项目追求不同的目标。就 Sui 而言，其核心目标是使各种资产能够被可靠地定义、并在链上无缝交互。因此，用其他区块链的范式或价值观来理解 Sui 的设计就是不合适的。在特殊情况下，Sui 优先考虑用户资产的返还和生态系统的稳定，而不是严格遵守抗审查——这一决定与其自身的长期愿景更加一致。此外，无论是 Sui 决定不审查相关交易，还是选择对 Cetus 的行为负责，如果背后有程序合法性，这两个决定都是合理的。

基于可信执行环境的私密证明委托

PSE 研究开发团队使用 Intel TDX 构建了一个基于可信执行环境（Trusted Execution Environment）的系统，用于安全的零知识证明委托。该系统允许客户端在不泄露输入的前提下，将大规模的证明任务私密地外包出去。相比受限于硬件能力的移动端本地证明，基于 TEE 的证明方案能够在目前就支持更大规模的陈述，并且随着证明系统的改进持续扩展。作为一种由硬件支撑的解决方案，TEE 能够兼容未来在软件层面的进展（例如更快的证明系统、更高效的工程实现），且只要信任模型被接受，就不会因这些进展而失效。

AI 与 ID：在代理、机器人、深度伪造等世界中的人类证明

我们正处于 AI（包括 AI 智能体、机器人、深度伪造等）深刻改变互联网的时代，随着 AI 的发展，网络上的身份认证变得愈发重要。a16z 的这期播客，讨论了在网上识别人类身份的「人类证明」（proof of human）问题，包括它为何重要，常见的问题有哪些，以及它在底层是如何运作的。

تاریخچه پیدایش پروتکل اردینالز

پروتکل اردینالز در ژانویه 2023 توسط کیسی رودرمور معرفی شد. این پروتکل حاصل دو به‌روزرسانی مهم در بیت‌کوین است:

1. سگ‌ویت (2017): جدا کردن داده‌های امضا از بدنه تراکنش‌ها برای افزایش فضای بلاک.

2. تپ‌روت (2021): افزایش حریم خصوصی و انعطاف‌پذیری در تراکنش‌ها.

رودرمور با استفاده از این دو ویژگی، سیستمی را طراحی کرد که به هر ساتوشی یک شناسه اختصاص می‌دهد و امکان الصاق داده به آن را فراهم می‌کند. اولین اینسکریپشن رسمی در دسامبر 2022 یک تصویر پیکسلی از یک جمجمه بود.

اینسکریپشن چیست؟

اینسکریپشن به معنای «حکاکی» دیجیتال است و در اینجا به ثبت داده‌هایی مانند تصویر، ویدئو یا متن بر روی بلاکچین بیت‌کوین اشاره دارد. برخلاف ان‌اف‌تی های سنتی که اغلب فقط لینک یا متادیتا ثبت می‌کنند، اینسکریپشن‌ها کل داده را در بخش ویتنس تراکنش ذخیره می‌کنند و به یک ساتوشی خاص متصل می‌شوند.

پروتکل اردینالز چگونه کار می‌کند؟

پروتکل اردینالز به هر ساتوشی یک شماره منحصر‌به‌فرد می‌دهد و آن را غیرقابل‌تعویض می‌کند. مراحل اصلی آن:

1. شماره‌گذاری: به هر ساتوشی یک شناسه اختصاص می‌یابد.

2. اینسکریپشن: با ابزارهایی مثل ابزار داده به ساتوشی الصاق می‌شود.

3. ذخیره‌سازی: در بخش ویتنس با حجم حداکثر ۴ مگابایت.

4. مالکیت: از طریق کلید خصوصی قابل‌انتقال است.

سایت‌هایی مانند ordinals.com و ord.io برای مشاهده این داده‌ها توسعه یافته‌اند.

انواع اینسکریپشن‌ها

کاربران داده‌های متنوعی را روی بیت‌کوین ثبت کرده‌اند:

• تصاویر: از هنر پیکسلی تا عکس‌های شخصی.

• متن: پیام، شعر یا اسناد.

• ویدئو/صوت: نسخه‌های فشرده و کوتاه.

• بازی‌ها: نسخه‌های ساده مانند دووم.

مزایای اینسکریپشن و اردینالز

1. تغییرناپذیری: داده‌ها دائمی و مقاوم در برابر سانسور هستند.

2. ارزش ذاتی: هر اینسکریپشن به یک ساتوشی متصل است.

3. درآمدزایی برای ماینرها: افزایش تراکنش‌ها = کارمزد بیشتر.

4. کاربرد بیشتر بیت‌کوین: فراتر از پول دیجیتال.

5. امنیت بالا: بدون نیاز به سرور خارجی.

معایب و چالش‌ها

1. افزایش حجم بلاکچین: رشد حجم تا بالای ۵۰۰ گیگابایت تا مارس 2025.

2. کارمزد بالا: گاهی تا ۴۰ دلار در سال 2023.

3. پیچیدگی فنی: راه‌اندازی نود و ساخت اینسکریپشن ساده نیست.

4. اختلاف‌نظر: برخی معتقدند این کاربرد با فلسفه بیت‌کوین در تضاد است.

5. مقیاس‌پذیری: ممکن است شبکه را کند کند.

تأثیرات بر اکوسیستم بیت‌کوین

1. تأثیر اقتصادی

در سال 2023، بیش از ۲۰ میلیون اینسکریپشن ثبت شد. این روند در 2024 نیز ادامه داشت و منجر به شکل‌گیری بازار ان‌اف‌تی های بیت‌کوینی شد.

2. تأثیر فنی

ابزارهای جدید مانند کیف پول اسپرو و پلتفرم‌های معاملاتی مانند پلتفرم معاملاتی مجیک ادن توسعه یافتند.

3. تأثیر اجتماعی

جامعه به دو دسته تقسیم شد: موافقان نوآوری و مخالفان تغییر مسیر بیت‌کوین.

مقایسه اینسکریپشن و ان‌اف‌تی های اتریوم

| ویژگی | اینسکریپشن بیت‌کوین | ان‌اف‌تی اتریوم | | -------------- | ------------------- | --------------- | | محل ذخیره داده | روی بلاکچین | خارج از بلاکچین | | تغییرناپذیری | بسیار بالا | وابسته به سرور | | هزینه ساخت | متغیر (کارمزد) | متغیر (گس) | | امنیت | بسیار بالا | متوسط تا بالا | | انعطاف‌پذیری | محدود | بالا | | دسترسی | پیچیده | ساده |

تحولات اخیر (2024 و اوایل 2025)

• پس از هاوینگ: وابستگی بیشتر ماینرها به کارمزد و رشد اینسکریپشن.

• پشتیبانی صرافی‌ها: اضافه شدن قابلیت معامله در بایننس و کراکن.

• کاربردهای نو: ثبت اسناد قانونی، بازی‌های تعاملی و هنر دیجیتال.

آینده اینسکریپشن و اردینالز

چشم‌انداز آینده بستگی به:

1. پذیرش کاربران.

2. راهکارهای مقیاس‌پذیری.

3. رقابت با دیگر بلاکچین‌ها.

4. تحولات قانونی.

در بهترین حالت، بیت‌کوین به پلتفرمی چندمنظوره تبدیل خواهد شد.

نتیجه‌گیری

اینسکریپشن و پروتکل اردینالز فرصتی برای نوآوری در بیت‌کوین ایجاد کرده‌اند. اگرچه چالش‌هایی وجود دارد، اما پتانسیل این فناوری برای ایجاد دارایی‌های دیجیتال دائمی، غیرقابل‌تغییر و امن بسیار بالاست. آینده این ابزار به مسیر فنی، پذیرش اجتماعی و سیاست‌گذاری‌های جهانی بستگی خواهد داشت.

شروع ماجرا:

همه چیز از 1401 شروع شد، زمانی که به خاطر وارد کردن ضربات متعدد به بیضه توسط بسیجیان و لباس شخصی های جمهوری اسلامی و شروع درد مبهم و تیر کشیدن توی بیضه‌هام حس می‌کردم که با گذشت زمان شدیدتر می‌شد. اول فکر کردم یه چیز ساده‌ایه و خود به خود خوب می‌شه، اما با گذشت زمان متوجه شدم که این درد داره بدتر می‌شه که همون شب توی یازداشتگاه چندبار دکتر اومد بالای سرم و آمپول هایی برای کاهش دردم تزریق کرد و قرار شد بعد از آزادی به دکتر مراجعه کنم، اما چون فرصت مراجعه به دکتر رو نداشتم و کمی هم بیخیال بودم، این چک کردن دو سال طول کشید و در 1403 به دکتر مراجعه کردم

بعد از دو سال به دلیل اینکه میزان اسپرمم به شدت کاهش یافته بود و بیضه م داشت به شکل عجیب غریبی در میومد به پزشک مراجعه کردم، و بعد از انجام آزمایش سونوگرافی و اسپرم، دکتر سونوگرافی گفت بیضه چپم تخلیه شده، و علاوه بر اون رگ های خونی بیضه م هم آسیب دیده بوده که این یعنی واریکوسل گرید سه به همراه التهاب و ... که این یعنی سریعا عمل میشدم که حداقل بشه برای رگ ها و ورید های بیضه کاری کرد.

واریکوسل به وضعیتی گفته می‌شود که در آن وریدهای بیضه بزرگ و متورم می‌شوند، چیزی شبیه به واریس پا. این مشکل می‌تواند تأثیری بر کیفیت اسپرم و در نتیجه باروری داشته باشد و در گرید های بالا میتواند به عقیم شدن و عدم باروری منجر شود.

تصمیم برای عمل:

بعد از شنیدن تشخیص دکتر، خیلی ناراحت و نگران شدم. اما دکترم بهم اطمینان داد که با عمل جراحی می‌تونم این مشکل رو حل کنم. اولش خیلی ترسیدم، اما بعد از کلی تحقیق و مشورت با دوستان و خانواده، تصمیم گرفتم که عمل کنم.

زیر میزی قبل از عمل:

متاسفانه در ایران دکتر های جراح قبل از عمل درخواست واریز وجه به حساب خودشون یا دیگران(برای رد گم کردن و عدم شکایت بیمار) میکنند

روز عمل: استرس و آرامش

روز عمل فرا رسید. قبل از جراحی استرس داشتم، اما کادر درمان و خود دکتر  بسیار حرفه‌ای و دلسوز و مهربان بودند و حس اطمینان خوبی به من دادند. عمل تحت بیحسی از ستون فقرات و بیهوشی عمومی انجام شد و حدود یک ساعت طول کشید. وقتی به هوش آمدم، احساس درد نداشتم ولی تا چند ساعت از کمر به پایین بی حس بودم و حس خواب‌آلودگی داشتم.

نکته: بعد از عمل حتما آب، آبمیوه و اگر میتونید میوه و غذا بخورید!

دوران بهبودی: صبر و مراقبت

دوره نقاهت بعد از عمل، یه کم سخت بود. درد داشتم و فعالیت‌های روزمره‌ام محدود شده بود. اما با گذشت زمان، کم کم بهتر شدم و دردهام کمتر شد.

دوره بهبودی برای من حدود یک هفته طول کشید. پزشک توصیه‌هایی از جمله استراحت کافی، اجتناب از فعالیت‌های سنگین و مصرف داروهای مسکن برای کاهش درد داده بود. در روزهای اول کمی ورم و ناراحتی داشتم، اما به مرور زمان بهتر شدم. نکته‌ای که برای من بسیار مهم بود، که بعد از 6 روز سرکار برگشتم و شروع به فعالیت کردم، و بعد از یک هفته بخیه ها کشیده شد.

حدود یک ماه پس از عمل، دوباره به پزشک مراجعه کردم تا روند بهبودی بررسی شود. خوشبختانه همه چیز خوب پیش رفته بود و احساس سبکی و راحتی بیشتری داشتم. درد و حس سنگینی که قبل از عمل داشتم، کاملاً از بین رفته بود.

نتیجه‌گیری: چرا این تصمیم ارزشش را داشت

وقتی به گذشته نگاه می‌کنم، از اینکه تصمیم به انجام عمل واریکوسل گرفتم، کاملاً راضی‌ام. گرچه گرفتن تصمیم برای جراحی همیشه با ترس و تردید همراه است، اما تأثیری که این عمل بر کیفیت زندگی‌ام گذاشت، بدون تردید ارزشش را داشت. بعد از عمل، نه تنها از درد و ناراحتی رهایی یافتم، بلکه آرامش ذهنی بیشتری هم پیدا کردم. احساس سبکی و راحتی در فعالیت‌های روزمره، و از بین رفتن نگرانی‌هایی مثل احتمال ناباروری، باعث شد دوباره حس کنم به زندگی عادی برگشتم.

به همه کسانی که با واریکوسل درگیر هستند، پیشنهاد می‌کنم به بدن‌شان گوش دهند و حتماً از نظر پزشکان متخصص بهره بگیرند. هر کسی شرایط خاص خودش را دارد و تصمیم نهایی باید بر اساس بررسی دقیق و مشورت با پزشک گرفته شود. اما مهم‌ترین نکته این است که سلامتی‌تان را در اولویت بگذارید و اجازه ندهید ترس یا تردید، مانع رسیدن به بهبودی شود.

برای من، عمل واریکوسل مثل یک تولد دوباره بود. حالا با خیال راحت و بدون درد، زندگی می‌کنم و از این تصمیم مهم کاملاً خوشحالم. اگر شما هم با این مشکل مواجه هستید، نگران نباشید؛ با آگاهی و مشورت درست، می‌توانید آن را پشت سر بگذارید و به زندگی عادی خودتان بازگردید.

نکات مهم:

• اگر درد یا ناراحتی در ناحیه بیضه‌ها دارید، حتما به پزشک اورولوژی مراجعه کنید.

• از خود درمانی خودداری کنید.

• عمل واریکوسل یک عمل ساده و بی خطر است.

• بعد از عمل به توصیه‌های پزشک عمل کنید.

I've wanted to write this piece for months. Not because I have anything against Jack Mallers personally - quite the opposite. But because I've watched a pattern emerge in Bitcoin that mirrors one of the most chilling dynamics in Atlas Shrugged: the systematic destruction of our most productive builders by the very people who should be celebrating them.

We are the looters. And Jack might just be our Hank Rearden.

The Underdog's Dilemma

There's a cruel irony in how we treat success in Bitcoin. We champion the underdog, root for the builder in the garage, celebrate the cypherpunk taking on the establishment. But the moment that underdog succeeds - the moment they scale, grow, and inevitably have to navigate the messy realities of the existing system - we turn on them with the ferocity of the same establishment we claim to oppose.\ \ Jack began building Zap (which evolved into Strike) from his parents home in Chicago. Strike has grown into one of the most seamless fiat-to-bitcoin on-ramps for everyday users. No complexity, just pure utility. From day one, he's operated at a level of transparency that would make most CEO's uncomfortable. He's been building in public, taking feedback, admitting mistakes, and iterating - sometimes within hours of criticism.

The Rearden Parallel

In Atlas Shrugged, Hank Rearden creates Rearden Metal - a revolutionary alloy that's stronger, lighter, and more efficient than anything that came before. Instead of celebration, he faces endless scrutiny, regulation, and demands to prove is worthiness. The people who benefit from his innovation spend their time questioning his motives, dissecting his business practices, and demanding he justify his success.

Sound familiar?

Jack comes from a finance background - his father and grandfather were in the industry. This isn't a liability; it's an asset. He understands the beast we're fighting. He's been a Bitcoiner since 2013 with a spotless track record in a space littered with exit scams and broken promises. His values align with proof of work, individualism, and the radical idea that bitcoin is for everyone.

Yet when he helps launch 21 Capital, we don't see innovation - we see betrayal. When he navigates regulatory requirements to build products that can actually reach mainstream adoption, we don't see pragmatism - we see capitulation.

The Scarred Perspective

Our skepticism isn't entirely unfounded. We've been burned before. Mt. Gox, FTX, Three Arrows Capital, Celcius, Terra/ LUNA, BlockFi, Bitconnect, Voyager, QuadrigaCX - the graveyard of Bitcoin is littered with the corpses of trusted institutions. We've learned, painfully, that trust must be earned and verified.

But somewhere along the way, our healthy skepticism has metastasized into destructive paranoia. We've become so focused on protecting ourselves from the next SBF that we're attacking the people building the future we claim to want.

I'm guilty of this myself. I've made scathing attacks on my Nostr feed, comparing Jack to SBF, scrutinising contract clauses about re-hypothecation, and questioning his every move privately. I was viewing his actions through the lens of collective trauma rather than the reality of his long track record.

The Looters Paradox

Here's the uncomfortable truth: we're not just passive observers in this drama. We're active participants. We're the looters.

In Atlas Shrugged, the looters don't necessarily steal directly. They steal time, energy, and focus. They create bureaucracy, demnd endless justification, and burden the productive with the weight of constant explanation. They don't build competing products - they just tear down what others have built.

Everytime we demand Jack explain his business model for the hundredth time, we're stealing his time. Every time we scrutinize his partnerships without offering alternatives, we're creating bureaucracy . Everytime we attack his character rather than his arguments, we're furthering the system we claim to oppose.

The free market will create products whether we like them or not. People will build services that use bitcoin as collateral, create lending products, and navigate regulatory frameworks. The question isn't whether these products will exist - it's whether they'll be built by people who share our values or by those who don't.

The Atlantis Risk

The producers eventually withdraw from society in Atlas Shrugged, retreating to Galt's Gulch (Atlantis) and leaving the looters to face the consequences of their destructive behaviour. The economy collapses because the people who actually build things decided it wasn't worth the hassle anymore.

We're walking dangerously close to this precipice in Bitcoin. We're creating an environment where our most capable builders might just decide it's not worth it. Where the hassle of dealing with our constant scrutiny and bad-faith attacks outweighs the mission of building the future.

Jack has been more patient with our criticism than we deserve. He's addressed concerns publicly, changed the course when necessary, and continued building despite the noise. But patience has limits. At some point, even the most mission-driven builders will ask themselves: "Why am I doing this?"

The Path Forward

I don't know enough about finance to fully understand everything Jack is building with 21 Capital. Neither do most of his critics. But I know enough about Bitcoin to recognise someone who's been fighting the good fight for over a decade.

This doesn't mean we should trust blindly. It doesn't mean we should stop asking questions or demanding transparency. But it does mean we should approach our builders with the same benefit of the doubt we'd want for ourselves.

We need to distinguish between healthy skepticism and destructive paranoia. Between holding people accountable and tearing them down. Between being vigilant and being looters.

The fiat system is the real enemy here. It's massive, entrenched, and infinitely resourcesful. It will adapt, co-opt, and corrupt everything it touches. Fighting it requires builders who are willing to get their hands dirty, navigate imperfect systems, and make pragmatic compromises while holding onto their core values.

We can continue to be looters, tearing down what we don't understand and driving our best builders toward their own version of Atlantis. Or we can be what we claim to be: supporters of the free market, believers of proof of work, and champions of those building the future.

Don't trust. Verify. But remember: verification works both ways.

So you've decided to join nostr! Some wide-eyed fanatic has convinced you that the "sun shines every day on the birds and the bees and the cigarette trees" in a magical land of decentralized, censorship-resistant freedom of speech - and it's waiting just over the next hill.

But your experience has not been all you hoped. Before you've even had a chance to upload your AI-generated cyberpunk avatar or make up exploit codenames for your pseudonym's bio, you've been confronted with a new concept that has left you completely nonplussed.

It doesn't help that this new idea might be called by any number of strange names. You may have been asked to "paste your nsec", "generate a private key", "enter your seed words", "connect with a bunker", "sign in with extension", or even "generate entropy". Sorry about that.

All these terms are really referring to one concept under many different names: that of "cryptographic identity".

Now, you may have noticed that I just introduced yet another new term which explains exactly nothing. You're absolutely correct. And now I'm going to proceed to ignore your complaints and talk about something completely different. But bear with me, because the juice is worth the squeeze.

Identity

What is identity? There are many philosophical, political, or technical answers to this question, but for our purposes it's probably best to think of it this way:

Identity is the essence of a thing. Identity separates one thing from all others, and is itself indivisible.

This definition has three parts:

• Identity is "essential": a thing can change, but its identity cannot. I might re-paint my house, replace its components, sell it, or even burn it down, but its identity as something that can be referred to - "this house" - is durable, even outside the boundaries of its own physical existence.
• Identity is a unit: you can't break an identity into multiple parts. A thing might be composed of multiple parts, but that's only incidental to the identity of a thing, which is a concept, not a material thing.
• Identity is distinct: identity is what separates one thing from all others - the concept of an apple can't be mixed with that of an orange; the two ideas are distinct. In the same way, a single concrete apple is distinct in identity from another - even if the component parts of the apple decompose into compost used to grow more apples.

Identity is not a physical thing, but a metaphysical thing. Or, in simpler terms, identity is a "concept".

I (or someone more qualified) could at this point launch into a Scholastic tangent on what "is" is, but that is, fortunately, not necessary here. The kind of identities I want to focus on here are not our actual identities as people, but entirely fictional identities that we use to extend our agency into the digital world.

Think of it this way - your bank login does not represent you as a complete person. It only represents the access granted to you by the bank. This access is in fact an entirely new identity that has been associated with you, and is limited in what it's useful for.

Other examples of fictional identities include:

• The country you live in
• Your social media persona
• Your mortgage
• Geographical coordinates
• A moment in time
• A chess piece

Some of these identites are inert, for example points in space and time. Other identies have agency and so are able to act in the world - even as fictional concepts. In order to do this, they must "authenticate" themselves (which means "to prove they are real"), and act within a system of established rules.

For example, your D&D character exists only within the collective fiction of your D&D group, and can do anything the rules say. Its identity is authenticated simply by your claim as a member of the group that your character in fact exists. Similarly, a lawyer must prove they are a member of the Bar Association before they are allowed to practice law within that collective fiction.

"Cryptographic identity" is simply another way of authenticating a fictional identity within a given system. As we'll see, it has some interesting attributes that set it apart from things like a library card or your latitude and longitude. Before we get there though, let's look in more detail at how identities are authenticated.

Certificates

Merriam-Webster defines the verb "certify" as meaning "to attest authoritatively". A "certificate" is just a fancy way of saying "because I said so". Certificates are issued by a "certificate authority", someone who has the authority to "say so". Examples include your boss, your mom, or the Pope.

This method of authentication is how almost every institution authenticates the people who associate with it. Colleges issue student ID cards, governments issue passports, and websites allow you to "register an account".

In every case mentioned above, the "authority" creates a closed system in which a document (aka a "certificate") is issued which serves as a claim to a given identity. When someone wants to access some privileged service, location, or information, they present their certificate. The authority then validates it and grants or denies access. In the case of an international airport, the certificate is a little book printed with fancy inks. In the case of a login page, the certificate is a username and password combination.

This pattern for authentication is ubiquitous, and has some very important implications.

First of all, certified authentication implies that the issuer of the certificate has the right to exclusive control of any identity it issues. This identity can be revoked at any time, or its permissions may change. Your social credit score may drop arbitrarily, or money might disappear from your account. When dealing with certificate authorities, you have no inherent rights.

Second, certified authentication depends on the certificate authority continuing to exist. If you store your stuff at a storage facility but the company running it goes out of business, your stuff might disappear along with it.

Usually, authentication via certificate authority works pretty well, since an appeal can always be made to a higher authority (nature, God, the government, etc). Authorities also can't generally dictate their terms with impunity without losing their customers, alienating their constituents, or provoking revolt. But it's also true that certification by authority creates an incentive structure that frequently leads to abuse - arbitrary deplatforming is increasingly common, and the bigger the certificate authority, the less recourse the certificate holder (or "subject") has.

Certificates also put the issuer in a position to intermediate relationships that wouldn't otherwise be subject to their authority. This might take the form of selling user attention to advertisers, taking a cut of financial transactions, or selling surveillance data to third parties.

Proliferation of certificate authorities is not a solution to these problems. Websites and apps frequently often offer multiple "social sign-in" options, allowing their users to choose which certificate authority to appeal to. But this only piles more value into the social platform that issues the certificate - not only can Google shut down your email inbox, they can revoke your ability to log in to every website you used their identity provider to get into.

In every case, certificate issuance results in an asymmetrical power dynamic, where the issuer is able to exert significant control over the certificate holder, even in areas unrelated to the original pretext for the relationship between parties.

Self-Certification

But what if we could reverse this power dynamic? What if individuals could issue their own certificates and force institutions to accept them?

Ron Swanson's counterexample notwithstanding, there's a reason I can't simply write myself a parking permit and slip it under the windshield wiper. Questions about voluntary submission to legitimate authorities aside, the fact is that we don't have the power to act without impunity - just like any other certificate authority, we have to prove our claims either by the exercise of raw power or by appeal to a higher authority.

So the question becomes: which higher authority can we appeal to in order to issue our own certificates within a given system of identity?

The obvious answer here is to go straight to the top and ask God himself to back our claim to self-sovereignty. However, that's not how he normally works - there's a reason they call direct acts of God "miracles". In fact, Romans 13:1 explicitly says that "the authorities that exist have been appointed by God". God has structured the universe in such a way that we must appeal to the deputies he has put in place to govern various parts of the world.

Another tempting appeal might be to nature - i.e. the material world. This is the realm in which we most frequently have the experience of "self-authenticating" identities. For example, a gold coin can be authenticated by biting it or by burning it with acid. If it quacks like a duck, walks like a duck, and looks like a duck, then it probably is a duck.

In most cases however, the ability to authenticate using physical claims depends on physical access, and so appeals to physical reality have major limitations when it comes to the digital world. Captchas, selfies and other similar tricks are often used to bridge the physical world into the digital, but these are increasingly easy to forge, and hard to verify.

There are exceptions to this rule - an example of self-certification that makes its appeal to the physical world is that of a signature. Signatures are hard to forge - an incredible amount of data is encoded in physical signatures, from strength, to illnesses, to upbringing, to personality. These can even be scanned and used within the digital world as well. Even today, most contracts are sealed with some simulacrum of a physical signature. Of course, this custom is quickly becoming a mere historical curiosity, since the very act of digitizing a signature makes it trivially forgeable.

So: transcendent reality is too remote to subtantiate our claims, and the material world is too limited to work within the world of information. There is another aspect of reality remaining that we might appeal to: information itself.

Physical signatures authenticate physical identities by encoding unique physical data into an easily recognizable artifact. To transpose this idea to the realm of information, a "digital signature" might authenticate "digital identities" by encoding unique "digital data" into an easily recognizable artifact.

Unfortunately, in the digital world we have the additional challenge that the artifact itself can be copied, undermining any claim to legitimacy. We need something that can be easily verified and unforgeable.

Digital Signatures

In fact such a thing does exist, but calling it a "digital signature" obscures more than it reveals. We might just as well call the thing we're looking for a "digital fingerprint", or a "digital electroencephalogram". Just keep that in mind as we work our way towards defining the term - we are not looking for something looks like a physical signature, but for something that does the same thing as a physical signature, in that it allows us to issue ourselves a credential that must be accepted by others by encoding privileged information into a recognizable, unforgeable artifact.

With that, let's get into the weeds.

An important idea in computer science is that of a "function". A function is a sort of information machine that converts data from one form to another. One example is the idea of "incrementing" a number. If you increment 1, you get 2. If you increment 2, you get 3. Incrementing can be reversed, by creating a complementary function that instead subtracts 1 from a number.

A "one-way function" is a function that can't be reversed. A good example of a one-way function is integer rounding. If you round a number and get 5, what number did you begin with? It's impossible to know - 5.1, 4.81, 5.332794, in fact an infinite number of numbers can be rounded to the number 5. These numbers can also be infinitely long - for example rounding PI to the nearest integer results in the number 3.

A real-life example of a useful one-way function is sha256. This function is a member of a family of one-way functions called "hash functions". You can feed as much data as you like into sha256, and you will always get 256 bits of information out. Hash functions are especially useful because collisions between outputs are very rare - even if you change a single bit in a huge pile of data, you're almost certainly going to get a different output.

Taking this a step further, there is a whole family of cryptographic one-way "trapdoor" functions that act similarly to hash functions, but which maintain a specific mathematical relationship between the input and the output which allows the input/output pair to be used in a variety of useful applications. For example, in Elliptic Curve Cryptography, scalar multiplication on an elliptic curve is used to derive the output.

"Ok", you say, "that's all completely clear and lucidly explained" (thank you). "But what goes into the function?" You might expect that because of our analogy to physical signatures we would have to gather an incredible amount of digital information to cram into our cryptographic trapdoor function, mashing together bank statements, a record of our heartbeat, brain waves and cellular respiration. Well, we could do it that way (maybe), but there's actually a much simpler solution.

Let's play a quick game. What number am I thinking of? Wrong, it's 82,749,283,929,834. Good guess though.

The reason we use signatures to authenticate our identity in the physical world is not because they're backed by a lot of implicit physical information, but because they're hard to forge and easy to validate. Even so, there is a lot of variation in a single person's signature, even from one moment to the next.

Trapdoor functions solve the validation problem - it's trivially simple to compare one 256-bit number to another. And randomness solves the problem of forgeability.

Now, randomness (A.K.A. "entropy") is actually kind of hard to generate. Random numbers that don't have enough "noise" in them are known as "pseudo-random numbers", and are weirdly easy to guess. This is why Cloudflare uses a video stream of their giant wall of lava lamps to feed the random number generator that powers their CDN. For our purposes though, we can just imagine that our random numbers come from rolling a bunch of dice.

To recap, we can get a digital equivalent of a physical signature (or fingerprint, etc) by 1. coming up with a random number, and 2. feeding it into our chosen trapdoor function. The random number is called the "private" part. The output of the trapdoor function is called the "public" part. These two halves are often called "keys", hence the terms "public key" and "private key".

And now we come full circle - remember about 37 years ago when I introduced the term "cryptographic identity"? Well, we've finally arrived at the point where I explain what that actually is.

A "cryptographic identity" is identified by a public key, and authenticated by the ability to prove that you know the private key.

Notice that I didn't say "authenticated by the private key". If you had to reveal the private key in order to prove you know it, you could only authenticate a public key once without losing exclusive control of the key. But cryptographic identities can be authenticated any number of times because the certification is an algorithm that only someone who knows the private key can execute.

This is the super power that trapdoor functions have that hash functions don't. Within certain cryptosystems, it is possible to mix additional data with your private key to get yet another number in such a way that someone else who only knows the public key can prove that you know the private key.

For example, if my secret number is 12, and someone tells me the number 37, I can "combine" the two by adding them together and returning the number 49. This "proves" that my secret number is 12. Of course, addition is not a trapdoor function, so it's trivially easy to reverse, which is why cryptography is its own field of knowledge.

What's it for?

If I haven't completely lost you yet, you might be wondering why this matters. Who cares if I can prove that I made up a random number?

To answer this, let's consider a simple example: that of public social media posts.

Most social media platforms function by issuing credentials and verifying them based on their internal database. When you log in to your Twitter (ok, fine, X) account, you provide X with a phone number (or email) and password. X compares these records to the ones stored in the database when you created your account, and if they match they let you "log in" by issuing yet another credential, called a "session key".

Next, when you "say" something on X, you pass along your session key and your tweet to X's servers. They check that the session key is legit, and if it is they associate your tweet with your account's identity. Later, when someone wants to see the tweet, X vouches for the fact that you created it by saying "trust me" and displaying your name next to the tweet.

In other words, X creates and controls your identity, but they let you use it as long as you can prove that you know the secret that you agreed on when you registered (by giving it to them every time).

Now pretend that X gets bought by someone even more evil than Elon Musk (if such a thing can be imagined). The new owner now has the ability to control your identity, potentially making it say things that you didn't actually say. Someone could be completely banned from the platform, but their account could be made to continue saying whatever the owner of the platform wanted.

In reality, such a breach of trust would quickly result in a complete loss of credibility for the platform, which is why this kind of thing doesn't happen (at least, not that we know of).

But there are other ways of exploiting this system, most notably by censoring speech. As often happens, platforms are able to confiscate user identities, leaving the tenant no recourse except to appeal to the platform itself (or the government, but that doesn't seem to happen for some reason - probably due to some legalese in social platforms' terms of use). The user has to start completely from scratch, either on the same platform or another.

Now suppose that when you signed up for X instead of simply telling X your password you made up a random number and provided a cryptographic proof to X along with your public key. When you're ready to tweet (there's no need to issue a session key, or even to store your public key in their database) you would again prove your ownership of that key with a new piece of data. X could then publish that tweet or not, along with the same proof you provided that it really came from you.

What X can't do in this system is pretend you said something you didn't, because they don't know your private key.

X also wouldn't be able to deplatform you as effectively either. While they could choose to ban you from their website and refuse to serve your tweets, they don't control your identity. There's nothing they can do to prevent you from re-using it on another platform. Plus, if the system was set up in such a way that other users followed your key instead of an ID made up by X, you could switch platforms and keep your followers. In the same way, it would also be possible to keep a copy of all your tweets in your own database, since their authenticity is determined by your digital signature, not X's "because I say so".

This new power is not just limited to social media either. Here are some other examples of ways that self-issued cryptographic identites transform the power dynamic inherent in digital platforms:

• Banks sometimes freeze accounts or confiscate funds. If your money was stored in a system based on self-issued cryptographic keys rather than custodians, banks would not be able to keep you from accessing or moving your funds. This system exists, and it's called bitcoin.
• Identity theft happens when your identifying information is stolen and used to take out a loan in your name, and without your consent. The reason this is so common is because your credentials are not cryptographic - your name, address, and social security number can only be authenticated by being shared, and they are shared so often and with so many counterparties that they frequently end up in data breaches. If credit checks were authenticated by self-issued cryptographic keys, identity theft would cease to exist (unless your private key itself got stolen).
• Cryptographic keys allow credential issuers to protect their subjects' privacy better too. Instead of showing your ID (including your home address, birth date, height, weight, etc), the DMV could sign a message asserting that the holder of a given public key indeed over 21. The liquor store could then validate that claim, and your ownership of the named key, without knowing anything more about you. Zero-knowledge proofs take this a step further.

In each of these cases, the interests of the property owner, loan seeker, or customer are elevated over the interests of those who might seek to control their assets, exploit their hard work, or surveil their activity. Just as with personal privacy, freedom of speech, and Second Amendment rights the individual case is rarely decisive, but in the aggregate realigned incentives can tip the scale in favor of freedom.

Objections

Now, there are some drawbacks to digital signatures. Systems that rely on digital signatures are frequently less forgiving of errors than their custodial counterparts, and many of their strengths have corresponding weaknesses. Part of this is because people haven't yet developed an intuition for how to use cryptographic identities, and the tools for managing them are still being designed. Other aspects can be mitigated through judicious use of keys fit to the problems they are being used to solve.

Below I'll articulate some of these concerns, and explore ways in which they might be mitigated over time.

Key Storage

Keeping secrets is hard. "A lie can travel halfway around the world before the truth can get its boots on", and the same goes for gossip. Key storage has become increasingly important as more of our lives move online, to the extent that password managers have become almost a requirement for keeping track of our digital lives. But even with good password management, credentials frequently end up for sale on the dark web as a consequence of poorly secured infrastructure.

Apart from the fact that all of this is an argument for cryptographic identities (since keys are shared with far fewer parties), it's also true that the danger of losing a cryptographic key is severe, especially if that key is used in multiple places. Instead of hackers stealing your Facebook password, they might end up with access to all your other social media accounts too!

Keys should be treated with the utmost care. Using password managers is a good start, but very valuable keys should be stored even more securely - for example in a hardware signing device. This is a hassle, and something additional to learn, but is an indispensable part of taking advantage of the benefits associated with cryptographic identity.

There are ways to lessen the impact of lost or stolen secrets, however. Lots of different techniques exist for structuring key systems in such a way that keys can be protected, invalidated, or limited. Here are a few:

• Hierarchical Deterministic Keys allow for the creation of a single root key from which multiple child keys can be generated. These keys are hard to link to the parent, which provides additional privacy, but this link can also be proven when necessary. One limitation is that the identity system has to be designed with HD keys in mind.
• Key Rotation allows keys to become expendable. Additional credentials might be attached to a key, allowing the holder to prove they have the right to rotate the key. Social attestations can help with the process as well if the key is embedded in a web of trust.
• Remote Signing is a technique for storing a key on one device, but using it on another. This might take the form of signing using a hardware wallet and transferring an SD card to your computer for broadcasting, or using a mobile app like Amber to manage sessions with different applications.
• Key sharding takes this to another level by breaking a single key into multiple pieces and storing them separately. A coordinator can then be used to collaboratively sign messages without sharing key material. This dramatically reduces the ability of an attacker to steal a complete key.

Multi-Factor Authentication

One method for helping users secure their accounts that is becoming increasingly common is "multi-factor authentication". Instead of just providing your email and password, platforms send a one-time use code to your phone number or email, or use "time-based one time passwords" which are stored in a password manager or on a hardware device.

Again, MFA is a solution to a problem inherent in account-based authentication which would not be nearly so prevalent in a cryptographic identity system. Still, theft of keys does happen, and so MFA would be an important improvement - if not for an extra layer of authentication, then as a basis for key rotation.

In a sense, MFA is already being researched - key shards is one way of creating multiple credentials from a single key. However, this doesn't address the issue of key rotation, especially when an identity is tied to the public key that corresponds to a given private key. There are two possible solutions to this problem:

• Introduce a naming system. This would allow identities to use a durable name, assigning it to different keys over time. The downside is that this would require the introduction of either centralized naming authorities (back to the old model), or a blockchain in order to solve Zooko's trilemma.
• Establish a chain of keys. This would require a given key to name a successor key in advance and self-invalidate, or some other process like social recovery to invalidate an old key and assign the identity to a new one. This also would significantly increase the complexity of validating messages and associating them with a given identity.

Both solutions are workable, but introduce a lot of complexity that could cause more trouble than it's worth, depending on the identity system we're talking about.

Surveillance

One of the nice qualities that systems based on cryptographic identities have is that digitally signed data can be passed through any number of untrusted systems and emerge intact. This ability to resist tampering makes it possible to broadcast signed data more widely than would otherwise be the case in a system that relies on a custodian to authenticate information.

The downside of this is that more untrusted systems have access to data. And if information is broadcast publicly, anyone can get access to it.

This problem is compounded by re-use of cryptographic identities across multiple contexts. A benefit of self-issued credentials is that it becomes possible to bring everything attached to your identity with you, including social context and attached credentials. This is convenient and can be quite powerful, but it also means that more context is attached to your activity, making it easier to infer information about you for advertising or surveillance purposes. This is dangerously close to the dystopian ideal of a "Digital ID".

The best way to deal with this risk is to consider identity re-use an option to be used when desirable, but to default to creating a new key for every identity you create. This is no worse than the status quo, and it makes room for the ability to link identities when desired.

Another possible approach to this problem is to avoid broadcasting signed data when possible. This could be done by obscuring your cryptographic identity when data is served from a database, or by encrypting your signed data in order to selectively share it with named counterparties.

Still, this is a real risk, and should be kept in mind when designing and using systems based on cryptographic identity. If you'd like to read more about this, please see this blog post.

Making Keys Usable

You might be tempted to look at that list of trade-offs and get the sense that cryptographic identity is not for mere mortals. Key management is hard, and footguns abound - but there is a way forward. With nostr, some new things are happening in the world of key management that have never really happened before.

Plenty of work over the last 30 years has gone into making key management tractable, but none have really been widely adopted. The reason for this is simple: network effect.

Many of these older key systems only applied the thinnest veneer of humanity over keys. But an identity is much richer than a mere label. Having a real name, social connections, and a corpus of work to attach to a key creates a system of keys that humans care about.

By bootstrapping key management within a social context, nostr ensures that the payoff of key management is worth the learning curve. Not only is social engagement a strong incentive to get off the ground, people already on the network are eager to help you get past any roadblocks you might face.

So if I could offer an action item: give nostr a try today. Whether you're in it for the people and their values, or you just want to experiment with cryptographic identity, nostr is a great place to start. For a quick introduction and to securely generate keys, visit njump.me.

Thanks for taking the time to read this post. I hope it's been helpful, and I can't wait to see you on nostr!

อารมณ์ คือ โลก - โลก คือ อารมณ์ อารมณ์ ในโลกปัจจุบันรวมอยู่ที่ วัตถุนิยม อารมณ์ จึงเป็นปัจจัยแห่งเหตุการณ์ทุกอย่างในโลก

…. “ เดี๋ยวนี้คําว่า “อารมณ์” ในภาษาไทยนั้น หมายถึงความรู้สึกในใจมากกว่า; เช่น พื้นเพของจิตใจในขณะนั้นเป็นอย่างไร, เรียกว่าอารมณ์ของเขาเป็นอย่างไร, อารมณ์กําลังดี อารมณ์กําลังไม่ดี, นี่ คําว่าอารมณ์ในภาษาไทยใช้กันไปเสียอย่างนี้ ; มันคนละเรื่องกับในภาษาบาลี ซึ่งคําว่า “อารมณ์” หมายถึง สิ่งที่จะเข้ามากระทบ ตา หู จมูก ลิ้น กาย ใจ.

…. ถ้ากระทบแล้วเกิดความรู้สึกอย่างไร งุ่นง่านอยู่ในใจ อันนั้นไม่ได้เรียกว่าอารมณ์; อันนั้นก็เรียกว่ากิเลสอย่างอื่น เช่น เรียกว่าตัณหาบ้าง อุปาทานบ้าง; ถ้าจัดเป็นพวกขันธ์ ก็เรียกว่า เวทนาขันธ์บ้าง สัญญาขันธ์บ้าง สังขารขันธ์บ้าง; ถ้าเป็นความคิดที่งุ่นง่านก็เรียกว่า “สังขารขันธ์” ทั้งนั้น ดังนั้น เราจะต้องถือเอาคําว่าอารมณ์ในบาลีมาเป็นหลัก …. คําว่า อารมณ์ ที่จะเข้าใจกันง่ายๆ ก็หมายความว่า รูป เสียง กลิ่น รส โผฏฐัพพะ ที่จะมากระทบ ตา หู จมูก ลิ้น กาย นี้ ๕ อย่าง แล้วก็ความรู้สึกเก่าแก่ที่จะมาผุดขึ้นในใจอีก เรียกว่า ธัมมารมณ์ ที่จะมากระทบใจในปัจจุบันนี้ นี้ก็เป็นอันหนึ่ง เลยได้เป็นอารมณ์ ๖. อารมณ์กระทบ ตา หู จมูก ลิ้น กาย ๕ อย่างข้างนอกนี้ก็สําคัญไปพวกหนึ่ง ที่ปรุงขึ้นภายในสําหรับกระทบใจโดยไม่ต้องอาศัย ตา หู จมูก ลิ้น กาย ใจ เลย ในเวลานั้นก็ยังมีอยู่นี้เรียกว่าธัมมารมณ์ นี้ก็ยิ่งสําคัญ: แต่ว่ารวมกันแล้วก็เรียกว่า อารมณ์ ได้ด้วยกันทั้งนั้น แปลว่า สิ่งที่จะมากระทบกับ ตา หู จมูก ลิ้น กาย ใจ นั่นเอง

…. นี้ ดูให้ละเอียดตามตัวหนังสือ คําว่า “อารมณ์” แปลว่า ที่หน่วงบ้าง แปลว่า ที่ยินดีบ้าง, มันมีความหมายละเอียดมาก. ถ้าถือเอาความหมายอย่างคนที่มีตัวตนเป็นหลัก ธรรมะในฝ่ายฮินดูหรือฝ่ายพรหมณ์เขาก็จะพูดว่า สําหรับจิตหรืออาตมันเข้าไปจับฉวยเอา. แต่ถ้าพูดอย่างภาษาชาวพุทธพูดอย่างนั้นไม่ได้ เพราะไม่มีจิตไม่มีอาตมันชนิดนั้น แล้วจิตนี้ก็เพิ่งเกิดขึ้นหลังอารมณ์กระทบแล้ว; เลยต้องพูดตามพระบาลีที่ว่า อาศัยตาด้วย อาศัยรูปด้วย ย่อมเกิดจักษุวิญญาณ; ตาอาศัยกับรูปคืออารมณ์นั้นได้แล้วจึงจะเกิดจักษุวิญญาณ วิญญาณหรือจิตนี้เกิดทีหลัง

…. ฉะนั้น จึงไม่พูดว่า อารมณ์นี้เป็นสิ่งสําหรับจิตหรือตัวตนเข้าไปจับฉวยยึดเอา; ถ้าพูดอย่างนั้นมันก็จะเป็นฮินดูหรือพราหมณ์ไป คือมีตัวตนไป. พูดอย่างพุทธไม่มีตัวตน ทุกอย่างไม่ใช่ตัวตน เป็นสักว่าธาตุ, ได้การปรุงแต่งที่เหมาะแล้วมันก็ปรุงแต่งเป็นสิ่งใหม่ขึ้นมา ในนั้นอาจจะมีความรู้สึกโง่ไปว่าเป็นตัวเราก็ได้

…. ฉะนั้น คําว่าอารมณ์ ถ้าถือตามหลักในทางพุทธศาสนา ก็แปลว่า สิ่งที่อาศัยกันกับจิต จะเรียกว่าเป็นที่หน่วงของจิตมันก็ยังได้: ถ้าเข้าใจผิดมันก็ผิดได้: เรียกว่าสิ่งที่อาศัยกับอายตนะ แล้วก็เกิดเป็นความรู้สึกเป็นจิตขึ้นมา จิตกําลังหน่วงสิ่งนั้นเป็นอารมณ์ก็ได้ แต่จะให้เป็นตัวตนนั้นไม่ได้

…. โดยพยัญชนะก็มีอยู่อย่างนี้ ตัวพยัญชนะก็ยังกํากวม อารมฺมณํ หรือที่มาจาก อาลมฺพนํ ก็แปลว่า ที่หน่วงของจิต. ถ้าจะถือว่ามาจาก รม ที่แปลว่า ยินดี ก็แปลว่า มันเป็นสิ่งที่หลงใหลยินดีของจิต อย่างนี้ก็ยังได้อีก

…. แต่ขอให้รู้จักจากภายในดีกว่าที่จะมารู้จักจากตัวหนังสือ เมื่อตากระทบรูป เมื่อหูกระทบเสียง เป็นต้น มันเกิดขึ้นในใจ, แล้วสังเกตเอาที่นั่นก็แล้วกัน ว่ารูปที่มากระทบตานั้นมันคืออะไร? เสียงที่มากระทบหูนั้นมันคืออะไร? จะค่อยเข้าใจแจ่มแจ้งขึ้นทีละน้อยๆ ว่าอารมณ์นั้นคืออะไร? แต่ให้เข้าใจไว้ทีหนึ่งก่อนว่าสิ่งที่เรียกว่าอารมณ์ๆที่มากระทบนี้ มันยังไม่ดีไม่ชั่ว ยังไม่จัดเป็นสิ่งดีสิ่งชั่ว มันต้องผสมปรุงแต่งเป็นความคิดอย่างนั้นอย่างนี้เสียก่อน จึงจะจัดเป็นดีเป็นชั่ว อารมณ์ล้วนๆยังไม่ดีไม่ชั่ว จะได้รู้จักป้องกัน อย่าให้เป็นไปในทางชั่ว, ให้เป็นไปแต่ในทางดีได้ตามปรารถนา

…. นี้เรียกว่าโดยพยัญชนะ โดยตัวหนังสือ คําว่า “อารมณ์” แปลว่า เป็นที่ยินดีแห่งจิต, เป็นที่ยึดหน่วงแห่งจิต; โดยเฉพาะภาษาอภิธรรมแล้วก็ใช้คําว่า “เป็นที่หน่วงเอาของจิต”, คือจิตย่อมหน่วงสิ่งใดสิ่งหนึ่งเป็นอารมณ์ แปลคําว่าอารมณ์บ้าง, อาลัมพนะ แปลว่า เป็นที่หน่วงเอา.

…. เดี๋ยวนี้เราเรียนพุทธศาสนาไม่ใช่เรามาเรียนหนังสือบาลี, เราจะเรียนพระธรรมคําสอนของพระพุทธเจ้า เราก็ต้องดูสิ่งที่เรียกว่าอารมณ์ โดยหลักของธรรมชาติที่ปรุงแต่งกันอยู่ในใจดีกว่า; ก็อย่างพระบาลีที่ได้ว่ามาแล้วข้างต้นว่า จกฺขุญฺจ ปฏิจฺจ รูเป จ อุปฺปชฺชติ จกฺขุวิญฺญาณํ = เพราะอาศัยตาด้วย รูปด้วย ย่อมบังเกิดจักษุวิญญาณ ติณฺณํ ธมฺมานํ สงฺคติ ผสฺโส - การประจวบกันของ ๓ สิ่งนี้เรียกว่า “ผัสสะ”, ผสฺสปจฺจยา เวทนา = เพราะผัสสะเป็นปัจจัยจึงเกิดเวทนา, อย่างนี้เรื่อยไปจนเกิดทุกข์ จนเกิดความทุกข์, นี้เรียกว่าโดยธรรมชาติ

…. สิ่งที่เรียกว่าอารมณ์มีอยู่โดยธรรมชาติที่จะเข้ามาอาศัยกันกับตาข้างใน ที่มีอยู่ในตัวคน. แล้วจะเกิดจักษุวิญญาณ เป็นต้น ขึ้นในตัวคน; จะเกิด ผัสสะ เวทนา ตัณหา อุปาทาน ภพ ชาติ ขึ้นในตัวคน; นี้โดยธรรมชาติ พระพุทธเจ้าท่านบันดาลอะไรไม่ได้ : ธรรมชาติเป็นอยู่อย่างนี้ แต่ท่านรู้เรื่องนี้ท่านจึงนํามาสอนว่า ธรรมชาติมันมีอยู่อย่างนี้ เราจะต้องเข้าใจให้ถูกต้อง โดยที่จะป้องกันความทุกข์ไม่ให้เกิดขึ้นมาได้, หรือถ้าเกิดขึ้นมาได้ก็จะดับเสียได้

…. เราควรจะรู้จักอารมณ์ในฐานะที่เป็นธรรมชาติอันหนึ่ง ที่มีอยู่ตามธรรมชาติ แล้วที่จะเข้ามาทําเรื่องทําราวขึ้นในจิตใจของคนเราให้เกิดปัญหายุ่งยากนี้ให้ดีๆ นี้เรียกว่ารู้จักอารมณ์จากธรรมชาติโดยตรงอย่างนี้ ดีกว่าที่จะรู้จักตามตัวหนังสือ, ดีกว่าที่จะรู้จักตามคําบอกเล่าบางอย่างบางประการที่มันไม่มีประโยชน์อะไร. รู้จักตามคําบอกเล่าก็รู้จักตามที่พระพุทธเจ้าท่านตรัสดีกว่า แต่แล้วยังไม่รู้จักตัวจริง จนกว่าจะมารู้จักจากที่เมื่ออารมณ์มากระทบตา หู จมูก ลิ้น กาย ใจ เข้าจริงๆ : นั่นจึงจะรู้จักอารมณ์ รู้จักผลที่เกิดขึ้นจากการกระทบของอารมณ์, รู้จักต่อไปตามลําดับ จนแก้ปัญหาต่างๆ ได้

…. นี่ ขอร้องให้รู้จักสิ่งที่เรียกว่า อารมณ์ ในฐานะที่เป็นธรรมชาติอันหนึ่ง ที่มีอยู่ตามธรรมชาติ ที่จะเข้ามากระทบอายตนะภายใน คือ กระทบ ตา หู จมูก ลิ้น กาย ใจ แล้วมีเรื่องมีราวมีปัญหา

อารมณ์ คือ โลก - โลก คือ อารมณ์ …. “ ที่นี้จะให้ดูต่อไปอีก ว่าโดยข้อเท็จจริงที่เป็นอยู่แล้ว อารมณ์นั้นคืออะไร? ถ้าจะพูดโดยข้อเท็จจริงหรือตามสถานการณ์ที่เป็นอยู่จริงในชีวิตของคนเรา อารมณ์มันก็คือ “โลก” นั่นเอง. เดี๋ยวนี้เราไม่รู้จักโลกในฐานะอย่างนี้, เราไปเข้าใจความหมายของคําว่าโลกแคบไปบ้าง หรือว่าเขวไปบ้าง.

…. ถ้าจะรู้ตามหลักพระพุทธศาสนาแล้ว โลกทั้งหมดก็คือสิ่งที่จะมาปรากฏแก่ ตา หู จมูก ลิ้น กาย ใจ ของเรา, เรามีเพียง ๖ อย่าง, แล้วมันก็ ปรากฏได้เพียง ๖ ทาง, มากกว่านั้นมันปรากฏไม่ได้ ดังนั้น โลกก็คือสิ่งที่จะมาปรากฏแก่ ตา หู จมูก ลิ้น กาย ใจ ๖ อย่างของเรา. “โลก” ก็คือ รูป เสียง กลิ่น รส โผฏฐัพพะ ธัมมารมณ์ ๖ ประการเท่านั้น, ไม่มีอะไรมากไปกว่านั้น

…. ฉะนั้น รูป เสียง กลิ่น รส โผฏฐัพพะ ธัมมารมณ์ แต่ละอย่าง ๆ ก็คือ โลกในแต่ละแง่ละมุม นั่นเอง, ที่เป็น รูป เสียง กลิ่น รส โผฏฐัพพะ ก็อยู่ข้างนอก จะเรียกว่าอยู่ข้างนอกก็ได้, ที่เป็นอารมณ์เกิดขึ้นในใจ ปรุงขึ้นในใจก็เรียกว่าโลกข้างในก็ได้ แต่มันก็เป็นโลกอยู่นั่นแหละ เพราะมันเป็นสิ่งที่จิตจะต้องรู้สึก จิตรู้สึกก็เรียกว่าโลกสําหรับจิต ตา หู จมูก ลิ้น กาย รู้สึก ก็เรียกว่าโลกสำหรับ ตา หู จมูก ลิ้น กาย. นี้ขอให้มองให้เห็นชัดตามพระพุทธประสงค์ว่า โลก ก็คือ อารมณ์, อารมณ์ ก็คือ โลก.

…. แต่ทีนี้ พระพุทธเจ้าท่านมองลึกกว่านั้น ท่านตรัสถึงข้อที่ว่า ถ้ามันมาเกิดเป็นปัญหาแก่เราเมื่อไรจึงจะเรียกว่า “มันมี” พอมันมาเป็นปัญหาแก่เราเมื่อไรก็เรียกว่า “เป็นทุกข์”; เพราะว่าเราได้ไปจับฉวยยึดถือเอาตามประสาตามวิสัยของคนที่ไม่รู้จักโลก ถ้าพูดว่าไม่รู้จักโลกแล้วคนก็มักจะไม่ยอมรับ เพราะว่าเขาจะพูดว่าเขารู้จักโลกดี. ยิ่งพวกฝรั่งสมัยนี้ นักวิทยาศาสตร์ปราดเปรื่องนั้น เขาจะไม่ยอมรับว่าเขาไม่รู้จักโลก. แต่ถ้าพูดตามหลักพุทธศาสนาแล้วก็จะพูดได้ว่ายังไม่รู้จักโลกเลย เป็นคนตาบอดยิ่งกว่าตาบอด; เพราะว่าฝรั่งเหล่านั้นรู้จักโลกแต่ในแง่สําหรับจะยึดมั่นถือมั่นเป็น “ตัวกู ของกู” จะครองโลกจะอะไร เอาประโยชน์ทุกอย่าง; เขารู้จักโลกในแง่นี้ อย่างนี้พุทธบริษัทไม่เรียกว่า “รู้จักโลก”; แต่ถือว่าเป็นคนตาบอดต่อโลก, หลงยึดมั่นถือมั่นในโลก. เพราะว่าคนเหล่านั้นไม่รู้จักโลกโดยความเป็นอารมณ์ ๖ ประการ คือ รูป เสียง กลิ่นรส โผฏฐัพพะ ธัมมารมณ์, แล้วเป็น “มายา” คือ เอาจริงไม่ได้ เป็นของชั่วคราวๆ หลอกให้เกิดความรู้สึกยึดมั่นถือมั่น

…. นี้เรารู้จัก เราไม่ไปหลงยึดมั่นถือมั่นกับมัน นี้จึงเรียกว่า “คนที่รู้จักโลก” ไปตามหลักของพุทธศาสนา, ฉะนั้น จึงไม่ยึดมั่นถือมั่นสิ่งใดโดยความเป็นตัวตน หรือโดยความเป็นของตน, เรียกว่าเป็นผู้รู้จักอารมณ์ ๖ ประการนั้นก็คือรู้จักโลกทั้งปวง, แล้วก็ไม่หลงไปในโลกในแง่ใดแง่หนึ่ง นี้เรียกว่า อารมณ์ ก็คือ โลก นั่นเอง ในความหมายที่ลึกที่สุดของพระพุทธสาสนา ไม่ใช่โลกก้อนดิน, ไม่ใช่โลกก้อนกลมๆ นี้. แต่มันหมายถึงคุณค่าอะไรที่มันมีอยู่ในโลกกลมๆ นี้ ที่จะเข้ามามาทําให้เกิดปัญหา ที่ตา ที่หู ที่จมูก ที่ลิ้น ที่กาย ที่ใจ ของคน. นั่นแหละคือตัวร้ายกาจของสิ่งที่เรียกว่า โลก เราจะต้องรู้จักในส่วนนี้ให้เพียงพอ

อารมณ์ในโลกปัจจุบันมารวมที่วัตถุนิยม …. ทีนี้ ดูอีกแง่หนึ่งก็โดยปัญหาที่กําลังมีอยู่ อารมณ์ในโลกนี้ในฐานะที่มันเป็นตัวปัญหาที่กําลังมีอยู่ มันมารวมอยู่ที่คําว่า “วัตถุนิยม”: หมายความว่า ตา หู จมูก ลิ้น กาย ใจ นี้ มันเป็นฝ่ายชนะ ไปหลงใหลในอารมณ์ รูป เสียง กลิ่น รส โผฏฐัพพะ ฯลฯ, แล้วก็เกิดนิยมหลงใหลในวัตถุเหล่านั้น จนเกิดความคิดใหม่ๆ, ปรุงแต่งไปในทางที่จะให้หลงใหลในโลกยิ่งขึ้นๆ, ความเจริญก้าวหน้า ในโลกสมัยนี้เป็นไปแต่ในทางอย่างนี้ ฉะนั้น จึงไกลความสงบ, ไกลสันติภาพ ไกลอะไรออกไปทุกที. การที่มนุษย์ที่มีปัญญาในโลกสมัยนี้ โดยเฉพาะฝรั่งที่ก้าวหน้านั้นเขาก็จัดโลกไปแต่ในแง่ของวัตถุมากขึ้นๆ: มันก็ไกลจากสันติภาพ ไกลจากความสงบสุขยิ่งขึ้นทุกที

…. ความสะดวกสบายที่ทําให้เกิดขึ้นมาได้นั้น ไม่ได้ช่วยส่งเสริมเกิดสันติภาพ; แต่มันช่วยให้เกิดความหลงในโลกนั้นเองมากขึ้น แล้วก็ช่วยให้หลงใหลใน “ตัวกู ของกู”, ยึดมั่นถือมั่นเห็นแก่ตัวมากขึ้น รวมกันแล้วมันไม่มีทางที่จะเกิดสันติภาพหรือสันติสุขในโลกได้เลย, จึงกลายเป็นความหลอกลวงเหลือประมาณ โลกจึงกลายเป็นความหลอกลวง, หรือสิ่งที่หลอกลวงเหลือประมาณใน เวลานี้ เราเรียกกันว่า ติดบ่วง หรือว่า ติดเหยื่อของวัตถุนิยม. คําพูดทั้งหมดนี้ ล้วนแต่เป็นการแสดงให้เห็นว่า อารมณ์นี้คืออะไร สิ่งที่เรียกว่าอารมณ์นั้น คือตัวโลกที่กําลังหลอกลวงเราอยู่ทุกวันอย่างยิ่ง โดยเฉพาะในปัจจุบันนี้เป็นวัตถุนิยม นี้คืออารมณ์”

Inflation is one of the most significant factors affecting personal wealth and the economy yet it goes unnoticed until its effects become unavoidable. As the cost of goods and services rises, your purchasing power decreases, and this makes long-term financial planning more challenging.

What is inflation? Inflation is the general increase in prices of goods and the reduction of the purchasing power of money. It is commonly measured by : 1.Consumer Price Index (CPI)

2.Core Inflation

3.Producer Price Index (PPI)

Inflation occurs due to various factors, including increased demand and supply chain disruptions

Why is Inflation Important? Inflation is crucial because it affects the cost of living, purchasing power, and the economy as a whole. As prices rise money loses value making it harder for consumers to afford essentials if wages don’t keep up. It also influences interest rates as central banks ,adjust policies to control inflation, borrowing, savings, and investments.

How Inflation Affects Personal Wealth 1. Erosion of Purchasing Power As prices rise, the same amount of money used to buy more before now buys fewer goods and services. 2. Impact on Savings Your money sitting in savings accounts with little or no interest rates loses value over time. If the inflation rate exceeds the interest or profit earned on your savings, then it becomes affected 3. Effects on Investments Their impact is the most because inflation reduces the real value of future payments. 4.Wages & Employment Some businesses may cut costs by reducing roles in a department or reducing pay to keep the team members.

Everyone is affected by inflation.

How Do You Protect Your Wealth from Inflation? 1.Invest in Inflation-Protected Assets Stocks and real estate investments offer long-term growth potential.They give you ownership of a product, which you can use, resell or repackage as you please. 2.Alternative Investments If you have the stomach, commodities, cryptocurrency, and other non-traditional assets may provide inflation releaved. 3. Increase Income Streams Side hustles, passive income, and career advancements can help offset inflation’s impact. 4.Reduce Debt Nigerians are aware of Credit Houses pretending as Loan Sharks chasing debtors around with ridiculous messages of loved ones. In a period of inflation, those loans feel like a double punishment because of ridiculous interest rates and overwhelmed inflation. Whatever you can do to reduce your debt during this period will be life-changing. Also, non-interest debts should always be considered before going down a slippery slope.

Summary Nigeria — A Few Word One thing is clear — inflation persists in almost every corridor of the economy. Inflation is an inevitable part of economic cycles, but understanding its impact allows you to take proactive steps in protecting your wealth. But I believe you can maintain financial stability by following some of the steps above.

Be proactive!

The silent revolution: Ethereum's pivot to 'digital oil' could redefine crypto's future. While Bitcoin grabs headlines as digital gold, Ethereum is quietly transforming into something potentially more valuable—the essential infrastructure powering our digital economy. Ryan Berckmans reveals Ethereum's strategic shift from being just another cryptocurrency to becoming the foundation for stablecoins, tokenized assets, and global financial systems. With $480 billion in stablecoin volume and institutional players entering the space, Ethereum isn't just competing with Bitcoin—it's creating an entirely different value proposition. The question isn't whether ETH will hit $3K, but whether we're underestimating its long-term potential as the backbone of digital finance. Are you positioning yourself for the real crypto revolution happening right under our noses?

The $220 million crypto heist that took just minutes reveals a fatal flaw in DeFi security. While blockchain tech promises trustless transactions, the Cetus DEX exploit on Sui exposed how a single undetected bug in a math library became catastrophic. What's truly alarming isn't the hack itself but the revelation from Curve's founder that professional hackers-for-hire are now coordinating sophisticated cross-platform attacks. This signals a dangerous evolution in crypto threats where vulnerabilities aren't just discovered—they're hunted by organized teams with specialized skills. The industry faces a stark choice: invest aggressively in preventative security or watch as billions more vanish in seconds. Is your crypto truly safe, or just waiting for the right hacker to find its weakness?

Forget Lambos, think real estate tokens.

A European fund just dropped $3.4 million on tokenized real estate, marking the first time big money directly bought retail available tokens. This isn't just about crypto hype; it's about institutions embracing regulated crypto assets. Real World Assets (RWAs) are booming, up 260% this year, fueled by clearer US crypto rules. This surge pushes the tokenization sector past $23 billion.

Is this the start of crypto's mainstream moment?

Magdalena Carmen Frida Kahlo y Calderón[a] (Spanish pronunciation: [ˈfɾiða ˈkalo]; 6 July 1907 – 13 July 1954[1]) was a Mexican painter known for her many portraits, self-portraits, and works inspired by the nature and artifacts of Mexico. Inspired by the country's popular culture, she employed a naïve folk art style to explore questions of identity, postcolonialism, gender, class, and race in Mexican society.[2] Her paintings often had strong autobiographical elements and mixed realism with fantasy. In addition to belonging to the post-revolutionary Mexicayotl movement, which sought to define a Mexican identity, Kahlo has been described as a surrealist or magical realist.[3] She is also known for painting about her experience of chronic pain.[4]

Moscow Exchange Launches Bitcoin Futures For Qualified Investors

The Moscow Exchange, Russia’s largest exchange group, announced the launch of Bitcoin futures contracts on June 4th, 2025. The new derivatives will allow qualified investors in Russia to gain exposure to bitcoin prices without directly owning it.

The bitcoin futures contracts are cash-settled in Russian rubles and will be tied to the iShares Bitcoin Trust ETF (IBIT) that trades on U.S. exchanges. The IBIT ETF tracks the price of bitcoin, with each share representing 0.00068 bitcoin.

— Bitcoin Magazine (@BitcoinMagazine) June 4, 2025

Trading for the new bitcoin futures kicked off on Wednesday, with the first contracts expiring in September 2025. Each futures contract will be denominated in U.S. dollars per bitcoin but settled in rubles.

The launch of bitcoin futures on the Moscow Exchange comes after increased interest in Bitcoin exposure from Russian financial institutions. In May, Russia’s central bank formally permitted the offering of crypto-linked securities and derivatives to qualified investors. Prior to this, direct investment in Bitcoin was discouraged.

Sberbank, Russia’s largest bank, also announced plans to unveil its own bitcoin futures product in addition to the Moscow Exchange’s offering. The bank is launching exchange-traded notes that track Bitcoin’s price without direct ownership.

Bitcoin futures and other crypto-derivatives have seen surging interest recently as the Bitcoin and crypto industry matures. The move comes as an increasing number of countries have started adding Bitcoin to their reserves.

As Bitcoin adoption increases, investors and financial institutions are seeking more routes to gain exposure to Bitcoin. The launch of futures on the Moscow Exchange provides regulated bitcoin exposure to qualified Russian investors. But direct ownership of “physical” bitcoin remains off limits for most in Russia’s traditional finance sector.

Think your crypto is FDIC insured like your bank account? Big mistake. Crypto's wild west demands you be your own bank and security guard.

Crypto trading involves buying, selling, and exchanging digital currencies like Bitcoin or Ethereum, aiming to profit from price fluctuations. Security is paramount. Understand basic concepts like wallets (digital storage for your crypto), private keys (passwords to access your crypto), and blockchain (the technology that records all transactions).

Real world applications include using crypto for online purchases, international money transfers, and decentralized finance (DeFi) services like lending and borrowing. Current trends include the rise of DeFi, NFTs (non-fungible tokens), and increasing institutional investment.

Best practices? Use strong, unique passwords, enable two factor authentication (2FA) on all accounts, and store most of your crypto in cold wallets (offline storage) to protect against hacking. Be wary of phishing scams and fake websites. Never share your private keys or seed phrases.

Misconceptions? Crypto is not anonymous, transactions are not easily reversible, and past performance is not indicative of future results. Also, remember that regulations are evolving, so stay informed.

With crypto hacks on the rise, are you truly ready to secure your digital fortune, or are you leaving the door open for the next billion dollar heist?

Think crypto is just magic internet money? Think again.

Tokenomics is the secret sauce that makes or breaks a crypto project. It is the study of how tokens are created, distributed, and used within a blockchain ecosystem. Imagine it as the economic policy of a digital nation, dictating everything from supply and demand to user incentives.

Key features include supply caps, distribution models, utility, and burn mechanisms. A well designed token economy incentivizes user behavior, secures the network, and fosters long term growth. Poor tokenomics? It can lead to manipulation and project failure.

Zero Knowledge Proofs are like showing you know a password without revealing the password itself. This tech allows for private and secure transactions, verifying data without exposing the data itself. Think of voting systems where your vote stays secret, or supply chains where product details are confirmed without revealing the supplier.

What is the Fiat System and How Do Central Banks Set Interest Rates?

When central banks expand credit, they often increase the money supply by creating new money through mechanisms like quantitative easing (QE). For instance, a central bank may purchase government bonds, injecting money into the economy. This boosts liquidity but can lead to inflation when too much money chases limited goods and services.

Low interest rates make borrowing cheaper, encouraging spending and investment. However, this can overheat the economy, create speculative bubbles (e.g., in real estate), and drive inflation. Conversely, high interest rates restrict borrowing, slow the economy, and curb inflation but may trigger recessions.

How Would Interest Rates Work Under a Bitcoin Standard?

Under a Bitcoin standard, the money supply is fixed—only 21 million bitcoins will ever exist, with the last one mined around 2140. Unlike the fiat system, no central authority can manipulate the money supply or set interest rates. Instead, interest rates would be determined entirely by the market—by the supply and demand for capital.

If someone wants to borrow bitcoins, the interest rate would depend on negotiations between the lender and borrower. For example, if demand for loans is high and available bitcoins are scarce, interest rates would rise. Conversely, if there are ample bitcoin savings, rates might fall. This process would be fully decentralized and reflect real market conditions, not central bank decisions.

Since new bitcoins cannot be “printed,” there would be no inflation caused by an expanding money supply. Instead, bitcoin’s value would likely rise over time (deflation) as its fixed supply competes with growing demand. This could encourage saving over reckless spending, reshaping economic behavior.

Advantages of a Bitcoin Standard

1. Protection Against Inflation: Bitcoin’s fixed supply prevents currency devaluation, a common issue with fiat money. This safeguards savings and promotes long-term planning.

2. Decentralization: Without a central bank manipulating the market, economic decisions are made by individuals, not bureaucrats. This aligns with free-market principles where competition and innovation thrive.

3. Transparency and Security: The Bitcoin blockchain is public and immutable, ensuring transactions are transparent and secure from tampering.

4. Financial Freedom: Under a Bitcoin standard, individuals have full control over their money without government or bank interference, which is especially crucial in countries with unstable regimes or currencies.

5. Discipline in Lending: Without the ability to print money, lenders would be more cautious, reducing risky investments and speculative bubbles.

Potential Drawbacks and Why a Bitcoin Standard is Superior

One major argument against a Bitcoin standard is that it could slow economic growth. Low interest rates in the fiat system encourage borrowing and spending, driving economic activity. Under a Bitcoin standard, where interest rates are market-driven and likely higher, borrowing would be costlier, potentially limiting investments in new projects.

However, this critique misses a key point: economic growth fueled by artificially low interest rates and money printing is often unsustainable. It leads to debt crises, inflation, and bubbles that eventually burst, as seen in 2008. A Bitcoin standard promotes healthy economic discipline, where investments are based on real value, not artificial capital.

Moreover, bitcoin’s deflationary nature could shift how people view money. Instead of chasing endless growth, societies might prioritize sustainability, innovation, and efficiency. This could lead to a more stable and equitable economy in the long run.

Additional Considerations

A Bitcoin standard could transform global trade. Today, countries with fiat currencies often manipulate exchange rates to gain trade advantages. With bitcoin as a universal currency, such manipulations would vanish, fostering fairer competition.

Another aspect is energy efficiency. While bitcoin mining consumes energy, it incentivizes the development of renewable sources as miners seek cheap, sustainable energy. This could accelerate the transition to a green economy.

Conclusion

The Bitcoin standard offers a vision of an economy rooted in sound money, free markets, and financial freedom. While it may slow certain aspects of economic growth, it creates a more stable and sustainable system that protects individuals from inflation and centralized control. In a world where trust in institutions is waning, the Bitcoin standard is a step toward a fairer and more transparent future.

China

I might be wrong, but this is how I see it

This is a post within a series I am going to call "I might be wrong, but this is how I see it"

I have repeatedly found that my understanding of China is quite different from that of many libertarian-minded Americans. And so I make this post to explain how I see it. Maybe you will learn something. Maybe I will learn something.

It seems to me that many American's see America as a shining beacon of freedom with a few small problems, and China is an evil communist country spreading communism everywhere. From my perspective, America was a shining beacon of freedom that has fallen to being typical in most ways, and which is now acting as a falling empire, and China was communist for about a decade, but turned and ran away from that as fast as they could (while not admitting it) and the result is that the US and China are not much different anymore when it comes to free markets. Except they are very different in some other respects.

China has a big problem

China has a big problem. But it is not the communism problem that most Westerners diagnose.

I argue that China is no longer communist, it is only communist in name. And that while it is not a beacon of free market principles, it is nearly as free market now as Western nations like Germany and New Zealand are (being somewhat socialist themselves).

No, China's real problem is authoritarian one-party rule. And that core problem causes all of the other problems, including its human rights abuses.

Communism and Socialism

Communism and Socialism are bad ideas. I don't want to argue it right here, but most readers will already understand this. The last thing I intend to do with this post is to bolster or defend those bad ideas. If you dear reader hold a candle for socialism, let me know and I can help you extinguish it with a future "I might be wrong, but this is how I see it" installment.

Communism is the idea of structuring a society around common ownership of the means of production, distribution, and exchange, and the idea of allocating goods and services based on need. It eliminates the concept of private property, of social classes, ultimately of money and finally of the state itself.

Back under Mao in 1958-1962 (The Great Leap Forward), China tried this (in part). Some 50+ million people died. It was an abject failure.

But due to China's real problem (authoritarianism, even worship of their leaders), the leading classes never admitted this. And even today they continue to use the word "Communist" for things that aren't communist at all, as a way to save face, and also in opposition to the United States of America and Europe.

Authorities are not eager to admit their faults. But this is not just a Chinese fault, it is a fault in human nature that affects all countries. The USA still refuses to admit they assassinated their own president JFK. They do not admit they bombed the Nord Stream pipeline.

China defines "socialism with Chinese characteristics" to mean "the leadership of the Communist Party of China". So they still keep the words socialism and communism, but they long ago dropped the meanings of those words. I'm not sure if this is a political ploy against us in the West or not.

China's Marketplace Today

Today China exhibits very few of the properties of communism.

They have some common ownership and state enterprises, but not much differently than Western countries (New Zealand owns Air New Zealand and Kiwibank and Kiwirail, etc). And there are private enterprises all over China. They compete and some succeed and some fail. You might hear about a real-estate bank collapsing. China has private property. They have mostly free markets. They have money, and the most definitely have social classes and a very strong state.

None of that is inline with what communist thinkers want. Communist thinkers in China moan that China has turned away from communism.

Deng Xiaoping who succeeded Mao and attempted to correct the massive mistake, did much when he said "to get rich is glorious."

China achieved staggering rates of economic growth. 10% annually on average since 1977. Chinese economic reform started in 1979 and has continued through successive administrations (Deng, Jiang, Hu and now Xi).

China is now the world's largest economy (by GDP in PPP terms) since 2016.

I was first made aware of China's economic growth by Jim Rogers, an American commodities expert who travelled through China (and the rest of the world from 1990-1992) and in 2007 moved to Singapore where he ensured his daughters learned to speak Mandarin, because Jim knew where the economic growth was going to happen. Jim always spoke positively of China's economic prospects, and his view was so different from the "China is a nasty communist place" view that I had grown up with that my mind opened.

How can anybody believe they are still a communist country? In what world does it make sense that communism can produce such a massively booming economy? It doesn't make sense because it is simply wrong.

What does happen is that the CPC interferes. It lets the market do what markets do, but it interferes where it thinks oversight and regulation would produce a better result.

Western nations interfere with their markets too. They have oversight and regulation. In fact some of China's planned reforms had to be put on hold by Xi due to Donald Trump's trade war with China. That's right, they were trying to be even more free market than America, but America's protectionism prodded Xi to keep control so he could fight back efficiently.

Government oversight and regulation IMHO is mostly bad because it gets out of control, and there are no market forces to correct this. This gets even more extreme in a one-party system, so I can judge that China's oversight and regulation problems are very likely worse than those in Western nations (but I have no first hand experience or evidence).

Why do you keep saying CPC?

The Communist Party of China (CPC) is the ruling party in China. That is their official name. To call them the CCP is to concede to the idea that the British and Americans get to name everybody. I'm not sure who is right, since CPC or CCP is their "English" name (in Chinese it is 中国共产党 and Westernized it is Zhōngguó Gòngchǎndǎng). Nonetheless, I'll call them CPC because that is their wish.

Social Credit System

China moved from a planned economy to a market economy in stages. They didn't want any more sudden changes (can you blame them?). In the process, many institutions that have existed in the West for a long time didn't exist in China and they had to arise somehow. IMHO market forces would have brought these about in the private sector, but the one-party CP of China instead decided to create these.

One of those institutions was a credit score system. In the West we have TransUnion and Equifax that maintain credit ratings on people, and we have S&P, Moody's and Fitch that maintain credit ratings on companies. The domain of these ratings is their financial credit-worthiness.

So the People's Bank of China developed a credit information database for it's own needs. The government picked up on the idea and started moving towards a National Credit Management System. In 2004 it became an official goal to establish a credit system compatible with a modern market system. By 2006 banks were required to report on consumer creditworthiness.

But unchecked one-party governmental power will often take a good idea (credit worthiness data shared among private parties) and systematize it and apply it top-down, creating a solution and a new problem at the same time.

Nonetheless, originally it was about credit worthiness and also criminal convictions. That is no big scary thing that some right-wing American commentators will lead you to believe. In the US for example criminal records are public, so China's Social Credit System started out being no more over-reaching in scope than what Americans have lived under their entire lives, its only fault (a severe one) being centrally planned. And that remained the case up until about 2016 (in my estimation).

But of course there is always scope creep. As it exists today, I have reason to believe that CPC officials and even A.I. use judgement calls to score someone on how moral that person has been! Of course that is not a good idea, and IMHO the problem stems from one-party rule, and authoritarian administration of ideas that should instead be handled by the private sector.

Environmental, Social, and Governance

ESG is a system that came out of a couple basic ideas. The first is that many two-party transactions actually have externalities. They don't just affect the two parties, they also affect everybody else. When you fly in an airplane, you increase the CO2 in the atmosphere that everybody has to pay for (eventually). You may dispute that example, but that is no doubt one of the motivations of ESG.

But of course the recognition of this basic issue didn't lead all people towards market solutions (well it did, but those have been mostly messed up by others), but instead led many people towards ESG, which is a social credit scoring system which applies scores based on environmental and social side-effects of market transactions.

This is not at all the same as China's social credit system, which I described above. I hope you can see the difference.

In fact, China imported ESG from the West. Chinese companies, of their free will, in an attempt to court Western capital, achieve ESG goals for those Western investors. They have been playing this ESG game for 20 years just like the entire world has, because the West has imposed this faux-morality upon them. It isn't something China exported to us, it is something we exported to them.

I think China has avoided Woke-ism

My understanding of Chinese people, based on what I've heard many Chinese people say, is that China isn't affected by the Western woke-ism epidemic. They deride Western white woke people with the term "Baizuo". They have never sent an incompetent break dancer to the Olympics because of wok-ism. Competence is highly respected as is the competition to be the most competent, which (when augmented by a one-child policy which is no longer) has produced child prodigies like no other country has.

What about predatory loans of the Belt and Road initiative?

Predatory is an odd name for loans to people in need. The World Bank makes loans to people in need. China does too. China stands in opposition to Western Empire, and in that regard they produce their own alternative BRICS institutions. This is one of them.

There is AFAIK nothing more predatory about them. It is just that in some cases the borrowers have trouble paying them back and they get foreclosed upon. I don't think this is worthy of much discussion, except that the term "predatory" seems to me to be a propaganda device.

What about foreign influence from China?

China wants to influence the world, especially its own trading partners and potential trading partners. Doing that above board is fine by me.

But some of it is undoubtedly covert. Sometimes Chinese-born people run for public office in Western countries. In New Zealand we stood down some when it became clear they were being influenced too much by the CPC while being charged with representing their local town (dual loyalty issues). If only the USA would do the same thing to their dually-loyal politicians.

And all large nations run influence operations. The USA has the CIA, for example, and claims this "soft power" is actually the better alternative to what would otherwise be military intervention (but IMHO shouldn't be either). I'm not defending such operations (I despise them), I'm just explaining how China's position of exerting influence is not only no big deal and totally expected, it pales in comparison to the United States' influence operations which often become military excursions (something China rarely ever does).

What about the Great Firewall?

Yeah, that sucks. Again, single-party authoritarian control gone to extremes.

What about Human Rights Abuses? What about the Uyghur Genocide?

I don't like them. To the extent they are occurring (and I lean towards the belief that they are occurring), I condemn them.

China has anti-terrorism and anti-extremism policies that go too far. They end up oppressing and/or criminalizing cultures that aren't Chinese enough. But especially, China punishes dissent. Disagreement with the CPC is the high crime. It is the one-party rule that causes this problem. Anybody who speaks out against the CPC or goes against the state in any way is harshly punished. This happens to Uyghurs, to Falun Gong, to Tibetans, and to any religion that is seen as subversive.

Amnesty International and the UN OHCHR have documented issues around the Xinjiang Uyghur autonomous region, Tibet, LGBT rights, death penalty, workers rights, and the Hong Kong special administrative region. I am not about to pretend I know better than they do, but to some extent they go too far.

Amnesty International says this about the USA: Discrimination and violence against LGBTI people were widespread and anti-LGBTI legislation increased. Bills were introduced to address reparations regarding slavery and its legacies. Multiple states implemented total bans on abortion or severely limited access to it. Gender-based violence disproportionately affected Indigenous women. Access to the USA for asylum seekers and migrants was still fraught with obstacles, but some nationalities continued to enjoy Temporary Protected Status. Moves were made to restrict the freedom to protest in a number of states. Black people were disproportionately affected by the use of lethal force by police. No progress was made in the abolition of the death penalty, apart from in Washington. Arbitrary and indefinite detention in the US naval base Guantánamo Bay, Cuba, continued. Despite extensive gun violence, no further firearm reform policies were considered, but President Biden did announce the creation of the White House Office of Gun Violence Prevention. The USA continued to use lethal force in countries around the world. Black people, other racialized groups and low-income people bore the brunt of the health impacts of the petrochemical industry, and the use of fossil fuels continued unabated.

Amnesty international didn't even point out that the US government quashes free speech via pressure on social media corporations (because Amnesty International is far too lefty).

So who is worse, China or the US? I'm not going to make that judgement call, but suffice it to say that in my mind, China is not obviously worse.

China violates freedom of expression, association, and assembly of all people. This is bad, and a consequence mainly of one-party rule (again, what I think is the root cause of most of their ills). They arrest, detain, potentially kill anybody who publicly disagrees openly with their government. Clearly this is an excess of authoritarianism, a cancer that is very advanced in China.

As to organ harvesting of Uyghur Muslims, I think this is a myth.

China has dealt harshly with Muslim extremism. They don't offer freedom of religion to ISIS. And Amnesty International complains about that. But practically speaking you probably shouldn't respect the extremist religion of people who want to force everybody into a global caliphate through threat of violence. As you are well aware, some extremist Muslims (<1% of Islam) believe in using violence to bring about a global caliphate. Those extremists pop up in every country and are usually dealt with harshly. China has had to deal with them too.

I have watched two different Western YouTubers travel to Xinjiang province trying to find the oppressed Uyghurs and interview them. They can't find them. What they find instead are Uyghur Muslims doing their prayers five times a day at the local mosque. And also stories that the CPC pitched in some money to help them renovate the mosque. Maybe they were afraid it was a CPC trap and so they wouldn't speak freely. Amnesty International and the UN OHCHR say more than a million are "arbitrarily detained" and I'm not going to argue otherwise. But I'd be more convinced if there were a stream of pictures and news like there is out of Gaza, and it is suspicious that there isn't.

Conclusion

China is more like a Western nation that Westerners realize. Economically, militarily, socially. It still has a very serious obstacle to overcome: one-party rule. I don't think the one-party is going to voluntarily give up power. So most probably at some point in the future there will be a revolution. But in my opinion it won't happen anytime soon. For the most part Chinese people are living high on the hog, getting rich, enjoying the good life, in positive spirits about life, and are getting along with their government quite well at present.

When people talk about Bitcoin, it’s often described as a digital currency or a “speculative investment.” However, one of Bitcoin’s most fundamental and least understood roles is its function as a settlement network. To understand this, it’s worth comparing it with traditional settlement systems like SWIFT and exploring how Bitcoin offers a foundational layer for global value transfer decentralized and censorship-resistant.

First, let’s explain the difference between liquidity and settlement:

• Liquidity refers to the ease with which an asset can be converted into “money” without losing value.

• Settlement is the process of completing a transaction (actual transfer of value between parties).

SWIFT: The communication layer of the traditional financial system

The SWIFT system (Society for Worldwide Interbank Financial Telecommunication) is a network for communication between banks. It doesn’t move money directly but sends standardized messages that instruct financial institutions to perform transfers. The process involves multiple intermediaries, is costly, slow (can take days), and depends on trust between parties and local regulations.

Unlike SWIFT, Bitcoin is a self-sufficient network that enables the direct settlement of value between two parties, without the need for intermediaries. With each block mined, transactions are validated and recorded immutably in a global, transparent, and secure database: the timechain or "blockchain".

01 - Final settlement: Once a transaction is confirmed by a sufficient number of blocks, it is considered final and irreversible.

02 - Censorship resistance: There is no central entity that can block or reverse a valid transaction.

03 - Global availability: The network is accessible 24/7 anywhere in the world with internet access.

Just as gold once served as the foundation of monetary systems, Bitcoin is establishing itself as a base layer of digital value. This layer can support others, such as:

01 - The Lightning Network, which enables near-instant transactions with extremely low fees;

02 - Tokenized financial services, which can use Bitcoin as collateral or for inter-institutional settlement.

By functioning as a public and neutral settlement network, Bitcoin offers an alternative to the traditional system, which is fragmented, closed, and reliant on trust between institutions.

In summary, more than just a speculative asset, Bitcoin is emerging as a global financial infrastructure. As a settlement network, it removes intermediaries, reduces costs, increases security, and democratizes access to value transfer. In an increasingly interconnected and digital world, understanding Bitcoin’s role as a base layer may be key to understanding the future of money.

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

What I always liked about twitter was that it was never one place. You had all these sub-communities, yes, but the open nature of it allowed for wild interactions and the breaking of bubbles.

It was public square, dive bar, office water cooler, nightclub, and philosophy department all rolled into one. And you never knew who you were dealing with, and when those various "places" would interact.

My approach to twitter was always to never take things too seriously, and that's my approach for #nostr still. There is wisdom to "it's just a tweet bro" and I still believe that the secret to life is to send it, whether it be note, tweet, or in general.

Because you never know who you're dealing with, a great strategy is to assume that the other person is fourteen, or drunk, or really high, or senile, or all of the above. You wouldn't be mad if a stoned 14yr old would say something stupid to your face, so why be mad online?

I hope that we can rebuild what twitter used to be and what it was supposed to be, and transcend it. I believe that we're halfway there already. Given enough time and attention, I'm confident that we'll manage to build what so many on #nostr dream and hope for.

Zaps are already transcendent in that sense. As are cryptographic identities. Putting the user in control (as opposed to platforms) will be key to all of it, and I'm beyond excited to what is coming down the line with DVMs and even more exotic things.

The responsibility is on us to build it right, and to educate users as well as encourage them to take matters in their own hands. Nothing in life is free, not even freedom. We'll have to fight for it, and we'll have to take responsibility for ourselves and our actions.

Much needs to be built, much education needs to be done, much rektucation still needs to happen. But I remain optimistic, because the building blocks are there. Bitcoin works. Lightning works. Nostr works. Not perfectly, but it works.

I can't wait to see where we'll be in 5 years from now. It's wild to see where we are already. This is happening, and it's all happening because of you guys: focusing on the good that freedom tech can bring, pouring your time, money, effort, and attention into it.

I'm very grateful for that and to be part of it all. Thank you, from the bottom of my heart. I've said it before and I'll say it again: the future is bright, we just have a lot of building to do.

Think proving you're over 21 without showing your ID is impossible? Zero Knowledge Proofs make it real.

Zero Knowledge Proofs let you prove something is true without revealing the information itself. Imagine proving you know a password without saying it. It's like magic, but it's math.

They're used in crypto for private transactions, secure voting, and faster blockchains. Zcash and Aztec use them to hide transaction details. StarkWare uses them to make Ethereum faster.

But here's the twist: zk STARKs don't need a trusted setup, unlike zk SNARKs. This makes them more secure and decentralized.

Misconception alert: ZKPs aren't just for privacy. They also boost scalability and interoperability.

21… That number means something. A reminder that limits create value - both in Bitcoin and in life.

Every June 21st, skaters around the world remind us that freedom is something you make yourself - one push at a time only constrained by your own limitations.

This year in Vientiane, we’re proud to support one of the few real skate spots in Laos. A place built and held together by skaters for skaters.

Expect around 50 locals - from young kids to older heads - showing up not just to skate, but to hold space for each other. No ego, no filters, just boards, fun and respect.

Bircoiners have lots to learn from these communities on this regard. Go skate and you'll find out.

Starting January 1, 2026, the United Kingdom will impose some of the world’s most stringent reporting requirements on cryptocurrency firms.

All platforms operating in or serving UK customers-domestic and foreign alike-must collect and disclose extensive personal and transactional data for every user, including individuals, companies, trusts, and charities. 

This regulatory drive marks the UK’s formal adoption of the OECD’s Crypto-Asset Reporting Framework (CARF), a global initiative designed to bring crypto oversight in line with traditional banking and to curb tax evasion in the rapidly expanding digital asset sector.

What Will Be Reported?

Crypto firms must gather and submit the following for each transaction:

• User’s full legal name, home address, and taxpayer identification number
• Detailed data on every trade or transfer: type of cryptocurrency, amount, and nature of the transaction
• Identifying information for corporate, trust, and charitable clients

The obligation extends to all digital asset activities, including crypto-to-crypto and crypto-to-fiat trades, and applies to both UK residents and non-residents using UK-based platforms. The first annual reports covering 2026 activity are due by May 31, 2027.

Enforcement and Penalties

Non-compliance will carry stiff financial penalties, with fines of up to £300 per user account for inaccurate or missing data-a potentially enormous liability for large exchanges. The UK government has urged crypto firms to begin collecting this information immediately to ensure operational readiness.

Regulatory Context and Market Impact

This move is part of a broader UK strategy to position itself as a global fintech hub while clamping down on fraud and illicit finance. UK Chancellor Rachel Reeves has championed these measures, stating, “Britain is open for business – but closed to fraud, abuse, and instability”. The regulatory expansion comes amid a surge in crypto adoption: the UK’s Financial Conduct Authority reported that 12% of UK adults owned crypto in 2024, up from just 4% in 2021.

Enormous Risks for Consumers: Lessons from the Coinbase Data Breach

While the new framework aims to enhance transparency and protect consumers, it also dramatically increases the volume of sensitive personal data held by crypto firms-raising the stakes for cybersecurity.

The risks are underscored by the recent high-profile breach at Coinbase, one of the world’s largest exchanges.

In May 2025, Coinbase disclosed that cybercriminals, aided by bribed offshore contractors, accessed and exfiltrated customer data including names, addresses, government IDs, and partial bank details. 

The attackers then used this information for sophisticated phishing campaigns, successfully deceiving some customers into surrendering account credentials and funds.

“While private encryption keys remained secure, sufficient customer information was exposed to enable sophisticated phishing attacks by criminals posing as Coinbase personnel.”

Coinbase now faces up to $400 million in compensation costs and has pledged to reimburse affected users, but the incident highlights the systemic vulnerability created when large troves of personal data are centralized-even if passwords and private keys are not directly compromised. The breach also triggered a notable drop in Coinbase’s share price and prompted a $20 million bounty for information leading to the attackers’ capture.

The Bottom Line

The UK’s forthcoming crypto reporting regime represents a landmark in financial regulation, promising greater transparency and tax compliance. However, as the Coinbase episode demonstrates, the aggregation of sensitive user data at scale poses a significant cybersecurity risk.

As regulators push for more oversight, the challenge will be ensuring that consumer protection does not become a double-edged sword-exposing users to new threats even as it seeks to shield them from old ones.

Merchant Adoption

Steak n’ Shake

The US 🇺🇸 is a massive country, yet its BTC Map footprint has been lagging relative to other countries ... that is until now!

In what came as a nice surprise to our Shadowy Supertaggers 🫠, the Steak ’n Shake chain began accepting Bitcoin payments across hundreds of its locations nationwide (with some international locations too).

According to CoinDesk, the rollout has been smooth, with users reporting seamless transactions powered by Speed.

This marks a significant step towards broader Bitcoin adoption in the US. Now to drop the capital gains tax on cheesburgers!

SPAR Switzerland

In other chain/franchise adoption news, the first SPAR supermarket in Switzerland 🇨🇭 to begin accepting Bitcoin was this one in Zug. It was quickly followed by this one in Rossrüti and this one in Kreuzlingen, in what is believed to be part of a wider roll-out plan within the country powered by DFX's Open CryptoPay.

That said, we believe the OG SPAR crown goes to SPAR City in Arnhem Bitcoin City!

New Features

Merchant Comments in the Web App

Web App users are now on par with Android users in that they can both see and make comments on merchants.

This is powered by our tweaked API that enables anyone to make a comment as long as they pass the satswall fee of 500 sats. This helps keep spam manageable and ensure quality comments.

And just in case you were wondering what the number count was on the merchant pins - yep, they're comments!

Here is an 👉 Example merchant page with comments.

Merchant Page Design Tweaks

To support the now trio of actions (Verify, Boost & Comment) on the merchant page, we've re-jigged the design a little to make things a little clearer.

What do you think?

Technical

Codebase Refactoring

Thanks to Hannes’s contributions, we’ve made progress in cleaning-up the Web App's codebase and completing long overdue maintenance. Whilst often thankless tasks, these caretaking activities help immensely with long-term maintainability enabling us to confidently build new features.

Auth System Upgrades

The old auth system was held together with duct tape and prayers, and we’re working on a more robust authentication system to support future public API access. Updates include:

• Password hashing
• Bearer token support
• Improved security practices

More enhancements are in progress and we'll update you in the next blog post.

Better API Documentation

Instead of relying on tribal knowledge, we're finally getting around to writing actual docs (with the help/hindrance of LLMs). The "move fast, break everything" era is over; now we move slightly slower and break slightly less. Progress!

Database Improvements

We use SQLite, which works well but it requires careful handling in async Rust environments. So now we're untangling this mess to avoid accidental blocking queries (and the ensuing dumpster fires).

Backup System Enhancements

BTC Map data comes in three layers of fragility:

• Merchants (backed up by OS - the big boys handle this)
• Non-OSM stuff (areas, users, etc. - currently stored on a napkin)
• External systems (Lightning node, submission tickets - pray to Satoshi)

We're now forcing two core members to backup everything, because redundancy is good.

Lava is the most secure way to borrow against your bitcoin. Lava Loans allow you to borrow dollars using your bitcoin as collateral, all without giving up self-custody. No need to wait days, sign paperwork, bridge your bitcoin, or trust third-party custodians to take out a loan. All you have to do is set the terms of your loan within your Lava Vault, and you can get your loan capital within seconds.

Unlike other bitcoin-backed lending options, Lava is entirely self-custodial. You control your own keys and never have to transfer your bitcoin to a third party. Historically, most bitcoin-backed lending solutions required users to trust custodians with their bitcoin, exposing them to hacks, rehypothecation risk, insolvency, and seizures. This resulted in more than $24B in user funds lost in 2022 alone. Lending protocols on other chains like Ethereum or Solana require users to bridge their bitcoin, introducing additional custodial, bridge, smart contract, and platform risks. Both options are clunky, risky, and slow.

Lava Loans introduces a better model. We’ve built a borrowing protocol that works entirely on native bitcoin. Taking out a loan on Lava takes seconds, doesn't require paperwork, and allows you to maintain self-custody. Lava is the best option for simple, low-cost, and safe bitcoin-backed loans.

In this article we’ll dive into the key features of Lava Loans, how it is different from other borrowing options on the market, and explain how it works at a technical level.

Key Features of Lava

• Instant loans: No paperwork. Just answer 2 questions and get your loan within seconds.

• Low cost: We minimize costs by reducing loan risk, allowing us to offer the lowest rates on the market. All fees are made transparent at the start.

• Flexible amounts: Borrow exactly what you need.

• No Custodial Risk: Your BTC never leaves your control. There’s no risk of hacks, seizure, or rehypothecation. You can verify this yourself on-chain. Lava is the only loan product where you can independently verify—on-chain and in real time—that your bitcoin is not being rehypothecated.

• No Loan Initiation Risk: Using atomic swaps, your collateral only moves if your loan capital is already secured.

• No Repayment Risk: Repay your loan and your BTC is automatically returned, guaranteed by cryptography.

• Reduced Liquidation Risk: You choose your own blinded, off-chain price source, minimizing the chance of unfair liquidation.

• Bug-Minimized: Lava uses formally verified smart contracts on bitcoin (Discreet Log Contracts), meaning all contract outcomes are known and signed ahead of time. Execution is private and secure.

How It Works

The Lava Loans Protocol is built on top of bitcoin-native smart contracts, called Discreet Log Contracts (DLCs). DLCs enable conditional (oracle-based) contracts on bitcoin, meaning they can execute transactions based on pre-specified and approved conditions. Lava Loans are executed via custom DLCs that allow the borrower and lender to agree to the terms of a loan, enter into a contract based on those terms, and have the contract enforce the terms on-chain— all without requiring a third-party custodian.

DLCs allow for a trust-minimized borrowing experience, and they avoid many of the risks inherent with smart contracts on other platforms like Ethereum. DLCs operate on Bitcoin itself— you don’t need to move your coins to another chain or layer. They also mitigate bug risk because they are formally verified, meaning the output conditions of the contract are known from the beginning. This helps to avoid the exploits commonly seen in Ethereum. Because the contracts use off-chain oracles, they aren't susceptible to oracle manipulation by miners. Not only that, but these contracts are private, customizable (choose your own oracle), and scalable (minimal on-chain cost because execution happens off-chain).

Lava Loans are on-chain contracts between borrowers and lenders. The borrower and the lender agree on a loan amount (in USD), a collateral amount (in BTC), the loan duration, the interest rate, the loan-to-value (LTV) ratio at which liquidation happens, and a data feed (oracle) that will provide the Bitcoin price. When the contract is initialized, the collateral is locked and the loan capital is transferred to the borrower. The oracle feeds the price of Bitcoin into the contract on a continuous basis, and the contract executes according to its pre-defined parameters. As long as the borrower maintains a healthy LTV and repays their loan, their collateral is automatically returned to them upon completion.

Each Lava Loan goes through three phases:

Phase 1: Loan Initiation

• The loan is initialized via an atomic swap; the bitcoin collateral is locked in the smart contract and the loan capital is transferred from the lender to the borrower. Because this is done via an atomic swap, the borrower and lender do not have to trust one another or use an escrow. The collateral moves into the smart contract, and the loan capital is automatically sent to the borrower.

Phase 2: Active Loan

• Once the atomic swap is complete, the loan is active. The bitcoin collateral remains locked in the smart contract, and the borrower has access to their loan capital.

• While the loan is active, the oracle feeds the bitcoin price into the contract on an ongoing basis. This allows the contract to monitor the LTV.

Phase 3: Loan Termination

Once the loan is active, it can terminated in one of the following ways:

• Repaid: If the borrower repays the loan, the collateral is released to the borrower atomically.

• Liquidated: If the loan value reaches a pre-determined LTV or the borrower misses a payment, the collateral is immediately released to the lender for liquidation.

• Expired: If the borrower does not repay the loan before the loan term ends, some of the collateral, equivalent to principal plus interest, is released to the lender, and the rest is sent to the borrower.

• Fail-Safe: In rare scenarios where the loan process cannot be completed as expected due to unresponsive oracles, the protocol has built-in fail-safe mechanisms. These mechanisms ensure that the collateral is not lost.

As you can see, all of the loan terms and conditions are built into the smart contract. The borrower and lender agree on the terms, enter into the loan, and then the contract executes the pre-specified and approved transactions based on either the actions taken by the borrow/lender, or the price changes in BTC. As a user, you can verify at any point that your collateral sits on-chain, is locked in the contract, and isn’t being used or rehypothecated in any way.

Security

Lava Loans are designed to be the most secure option for Bitcoiners who want to borrow against their holdings. Lava’s approach is trust-minimized, bug-minimized, and verifiable for users.

Trust-Minimized

• Traditional platforms expose you to bridge, custodian, or bank risk. Lava lets you borrow against native-BTC directly in your vault. This means there can’t be rehypothecation, funds lost in custodial hacks, or asset confiscation.

• While other platforms require blind trust during loan initiation, Lava uses atomic swaps to ensure your BTC collateral only moves to the escrowed smart contract once the loan is in your hands.

• The uncertainty of receiving collateral post-repayment is a concern with many platforms. Lava uses cryptographic guarantees to ensure that once you fulfill your repayment, your BTC is promptly returned.

• You don’t have to trust a lender who can liquidate your BTC unjustly. With Lava, you choose your off-chain, blinded oracles per loan to provide price data, drastically reducing risks from malicious entities.

Bug-Minimized

• Lava’s bitcoin smart contract is formally-verified, meaning the output conditions to the contract are known ahead of time, minimizing technical risk. DLCs, the underlying technology Lava uses, use pre-signed, encrypted transactions to specify the output conditions to a contract ahead of time. Since all the output conditions to the contract are specified ahead of time, and then encrypted using adaptor signatures, the output conditions are known (money can only move to borrower/lender).

• Lava’s contracts have been audited by the best auditors in the industry, Antoine Riard from thelab31 and Conduition, as well as the core contributors to the cryptography behind DLCs.

Verifiable

• Lava is the only loan product where you can independently verify—on-chain and in real time—that your bitcoin is not being rehypothecated. When you borrow using Lava, you have cryptographic proof, not just legal or reputational assurances, that your collateral is secure.

• Lava’s oracle implementation is open-source.

• Lava’s oracles make daily attestations and calculate a median price across various price feeds to avoid flash crash and unreliable margin call risk.

How Lava Compares

Loan Payments + Fees

Users who take out a Lava Loan pay a one-time origination fee (currently 2%) to open a loan, and each loan has a determined, fixed interest rate for the duration of the loan. Interest rates depend on the length of the loan, but they currently start at 5% annually. Users can also extend their loan by paying an extension fee (currently 2%) at the time that the loan is extended.

Loans that are longer than one month in duration require users to make monthly payments on their loans. Because the terms of Lava Loans are set programmatically in the smart contract, users must make their monthly payments on time in order to avoid being liquidated. You can make your monthly payments using digital dollars (either those held in your Lava Vault, or by depositing USDC into the vault) or via bank transfer. Bank transfers may take several days to clear, so it’s important to plan ahead in order to make the payments on time. Lava offers notifications in advance of payment deadlines in order to allow you sufficient time to plan and make payments.

FAQ

What are oracles?

Oracles are independent data feeds that attest to the price of Bitcoin and feed that price into the contract. At Lava, we’ve built Sibyls, an open-source oracle implementation for bitcoin. Users can choose their own oracles, and oracles have zero knowledge about the contracts they influence. In the case of the Lava Loans Protocol, oracles also make off-chain attestations, and in doing so, this helps us avoid the increased fees and miner manipulation that comes from on-chain oracles. You can learn more about our oracles here.

Why does Lava use digital dollars?

To ensure a fast, trust-minimized loan, Lava uses smart contracts that require HTLC compatibility. Fiat doesn’t support this, so we use digital dollars (like USDC on Solana) — which you can instantly withdraw to your bank account.

What are bitcoin smart contracts?

Bitcoin smart contracts (also known as discreet log contracts) enable conditional (oracle-based) contracts on bitcoin. The way it works is that each party to a contract creates and shares encrypted signatures for each output condition to the contract. Each counterparty has confidence they can decrypt the encrypted signatures and use them correctly at the right time because they can verify the encryption: verify when they can decrypt the signatures and that the signatures are valid.

Bitcoin smart contracts are a better way to do smart contracts because they are secure, private, customizable, and scalable. They mitigate bug risk because they are formally verified, meaning the output conditions of the contract are known from the beginning. This helps avoid exploits you constantly see in Ethereum. Since these contracts use off-chain oracles, they aren't susceptible to oracle manipulation by miners. Not only that, but these contracts are private, customizable (choose your own oracle), and scalable (minimal on-chain cost because execution happens off-chain).

These contracts are zero knowledge in that the blockchain has zero knowledge about the contract, the oracles have zero knowledge about the contract, and the counterparty can verify the encryption without needing the decrypted material.

比特币正在主动引诱量子计算“破解自己”

引言：危机还是契机？

比特币和量子计算，这两个看似对立的存在，正在酝酿一场耐人寻味的博弈。许多人担心未来强大的量子计算机将秒破比特币的密码学基石，从而令区块链安全灰飞烟灭。然而，本文想传达的核心观点却截然相反：比特币不仅不会被量子破解打败，反而正在通过协议层的巧妙设计来“引诱”量子计算进入自己的游戏规则之中。通过诸如BIP-360等提案，比特币有望将量子计算的威胁转化为动力，开启一个“后挖矿时代”的全新正反馈经济体系，让“破解”本身成为新的挖矿机制。

这样的观点听起来近乎狂想，但背后有着深厚的技术逻辑支撑。我们将从基本的密码学原理谈起，逐步剖析量子计算的能力与局限，以及比特币协议在抗量子方向做出的结构性准备。最后，我们探讨一种大胆的经济模型：当量子计算被诱导去参与“破解竞赛”时，或许正是比特币凤凰涅槃、新经济形态崛起之机。

非对称加密的数学本质：“上帝视角”的陷门答案

非对称加密（如RSA、椭圆曲线加密ECC等）的核心在于存在一种单向函数：正向计算容易，反向推导极难。公钥可以视作某个难题的题目，私钥则相当于“上帝视角”提前知道的答案。一旦掌握私钥，就能轻松完成从答案到题目的逆推；而只有公钥时，想要逆推出私钥则被设计为在现实中不可行。这类单向难题通常通过陷门函数来实现——对合法持有者（私钥）来说，存在隐藏的捷径（陷门）可以快速解题；而对局外人来说，题目看似无解。

举例来说，比特币当前采用的ECC加密：私钥与公钥的关系就像“一次难以逆推的乘法”。给定私钥x，乘以基点G可轻易得到公钥点P = x·G，但已知P却无法高效求出x。这种不对称确保了签名者可以用私钥生成签名，而验证者只能用公钥验证签名而无法伪造。私钥掌握了解题的“上帝答案”，公钥则只能用于验证答案是否正确。

这一点在新型的抗量子算法中同样体现。以格密码（lattice cryptography）为例：Falcon等基于NTRU格的签名算法，其公钥可以被视为一个高维长基，私钥是对应的短基。pqshield.com在二维格子上的示意说明了这种不对称性：拥有短基（私钥）时，我们可以高效地找到距离某个目标点很近的格点解；但只有长基（公钥）时，我们顶多能验证某个给定解是否有效，却很难自行找到足够优质的解pqshield.com。换言之，私钥提供了一个陷门，允许持有者快速逆推答案，而公钥持有者只能望“题”兴叹。

图：在二维格子中，签名者持有的短基（私钥）可以高效求解出距离目标点（黑色方块）极近的格点解（绿色圆点）。绿色平行四边形表示短基下求解空间很小，因而容易找到最优解。这直观展示了陷门函数的威力：私钥掌握短基就如同拿到了解题捷径。

图：仅持有长基（公钥）时，使用相同算法得到的格点解（红色圆点）可能距离目标（黑色方块）很远。红色平行四边形代表在无陷门情况下求解范围巨大，找到最佳解极其困难。但验证者仍可用长基检查出某个解（如绿色点）确实是有效解pqshield.com。这体现了公私钥在计算能力上的不对称：私钥可求解，公钥仅可验证。

总而言之，非对称加密的安全性源自数学难题的单向性质和陷门结构。私钥就是那个隐藏的逆向通道，“上帝视角”的答案；公钥则是不具备捷径的信息，只够验证而无法逆推。从RSA的整数分解、ECC的离散对数，到Falcon的近似最近矢量问题，每一种公钥体制都是在构造“题目易出答案难逆”的格局，让持有陷门者轻松，旁观破解者绝望。

量子计算的原理与极限：并行穷举的神话与现实

量子计算机令人畏惧之处，在于其并行计算能力。通过量子叠加态，n个量子比特（qubit）可同时表示2^n种状态——仿佛能把指数级的可能性同时考虑。配合量子干涉与算法设计，量子计算机能够以远胜传统计算机的效率解决某些特定问题。其中最著名的就是Shor算法，它能在多项式时间内完成对大整数的质因数分解和离散对数求解。这正是传统公钥加密（RSA、ECC）的命门：一旦有足够强大的量子计算机，基于这些数学问题的公钥体制将不再困难，私钥可以由公钥“解密”而出coindesk.com。

然而，“并行穷举”的神话背后有严格的物理和工程学限制。首先是量子比特数量和质量的限制：当前的量子芯片规模远未达到破解现代加密所需的级别。据风险研究机构与专家调查，目前我们只有几十到几百个物理qubit，而要威胁256位ECC或2048位RSA，需要数百万高质量qubitdeloitte.com。不仅数量上相差几个数量级，现有量子芯片的纠错和降噪技术也远不成熟。量子比特极其敏感，微小噪声都会引入错误，真正实用的量子计算机需要对成千上万的物理比特进行纠错编码，形成稳定的逻辑比特。这个工程挑战之巨大，使得可攻破密码的量子计算机仍是多年之后的前景——多数专家预测大概还需十几年时间才可能出现实质威胁deloitte.com。

其次，量子计算并非万能破解，仅对特定问题有指数级加速。Shor算法擅长因数分解和离散对数，Grover算法可以对无结构的穷举搜索加速（将时间复杂度平方根降低）。但许多新兴的抗量子算法依赖的问题（如格上的最短向量问题SVP、最近向量问题CVP，或多变量方程、哈希预像等）目前并无高效量子算法。这些问题大多属于NP难类，甚至找近似解也极为困难emerginginvestigators.org。尽管量子计算提供并行试探能力，但对这类高度复杂的问题也爱莫能助。正如一项研究指出：SVP和CVP问题即便在量子计算机上依然“极端困难”，在可预见的将来仍足以保证安全性emerginginvestigators.org。Falcon所使用的NTRU格就是这样的难题代表——没有已知算法可以像Shor之于RSA那样，高效攻破NTRU问题。

最后，我们还需注意量子攻击的实际条件。量子破解比特币主要有两种情景：存储攻击和传输攻击deloitte.com。存储攻击指利用量子计算找出已公开公钥对应的私钥，从而盗取静态存放于链上某地址的币；传输攻击则是当交易广播（公钥暴露）后，在被矿工打包上链前的短暂窗口内，量子计算抢先推导私钥并盗转。这两种攻击对量子能力要求不同：存储攻击允许耗时几周甚至数月破解一个密钥，只要在币移动前完成即可；而传输攻击要求在区块确认之前（比特币约10分钟内，以太坊更短）秒破私钥deloitte.com。显然，目前和可预见的中期内，量子计算都远达不到传输攻击所需的即时破解水平；即便存储攻击，由于比特币区块链的UTXO模型（稍后详述），真正高价值、长时间暴露公钥的币也相对有限deloitte.com。因此，量子威胁虽然现实存在，但并非一夜之间让比特币崩溃的魔法。这反倒给予我们部署抗量子方案、引导量子力量“为我所用”的时间窗口。

抗量子密码学的三大结构前提

要让比特币真正抵御量子威胁，并把量子计算纳入自身生态，需要满足几个结构性前提。经过多年社区讨论和研究，以下三点被认为是比特币走向抗量子的关键设计要素：

1. UTXO模型：隐藏公钥缩短攻击窗口 – 比特币采用UTXO模型，每次交易都会生成新地址，公钥通常以哈希形式隐藏在地址中，直到你花费时才公布。这意味着量子计算只有在你发起交易后的很短时间内（交易确认前）才能获得公钥并尝试破解，大大压缩了攻击窗口anduro.iodeloitte.com。相较之下，账户模型（如以太坊）重复使用固定地址，公钥一旦被提取或首次使用后就长久暴露，使得65%以上的以太币当前都处于量子暴露风险中，而比特币约只有25%处于类似风险deloitte.com。UTXO模型通过“一次性地址”和“不用则公钥不出”的原则，天然提供了对抗量子存储攻击的第一道屏障。

2. “见证隔离”（SegWit）：模块化升级签名算法 – 抗量子方案的发展日新月异，比特币必须保持签名算法的可插拔升级能力。2017年的见证隔离升级正是为此奠定基础：SegWit将签名等见证数据与交易本体分离，并引入版本化的见证脚本格式。这使得添加新签名类型成为可能——通过软分叉引入新的输出类型和见证版本，就能兼容地支持不同算法delvingbitcoin.org。正如BIP-341利用SegWit扩展出了Taproot的Schnorr签名，比特币也可以扩展出抗量子签名的新地址类型而无需硬分叉或显著增加区块体积delvingbitcoin.org。这一模块化特性对于迎接未来各类抗量子算法至关重要，没有SegWit的铺垫，抗量子改造将困难重重。

3. 分级安全机制：根据价值和时效选择算法强度 – 由于UTXO的性质，每笔交易在花费时都会暴露其公钥。因此，安全策略不能“一刀切”，应允许根据币值大小或持有时长采用不同强度的抗量子算法。高价值的UTXO、长期未移动的“老币”，应使用更高安全级别但可能更重型的签名方案；反之，小额频繁交易可用较轻量的方案以兼顾效率和区块容量。好比Falcon提供了512和1024两种参数版本：Falcon-1024安全级别更高但签名稍大，而Falcon-512签名更小速度更快，适合资源受限场景emerginginvestigators.org。未来比特币或可同时支持多种抗量子算法或参数，用户按需选用，让“安全性”成为一种可以权衡和市场定价的链上资源。每一次支付都在安全与成本之间找到平衡，这将促使一个分层的安全市场形成——进一步论述见后文经济模型部分。

上述三大前提缺一不可：UTXO模型提供了基础的_安全缓冲_，SegWit机制给予_升级弹性_，分级算法让_经济可行性_落地。在这方面，比特币的体系结构远优于某些后来的公链。例如，以太坊的账户模型天生缺乏隐藏公钥的机制，地址就是固定的公钥哈希，一旦使用过私钥签名就永久暴露公钥，同时其交易脚本（EVM）对签名算法固定死，没有灵活插拔空间。这意味着以太坊想转向抗量子算法，必须经过极其痛苦的整体迁移或硬分叉——开发者需要为每个账户引入新密钥，新老算法并行过渡，智能合约地址、签名验证逻辑全部推倒重来。这种难度令人生畏，以至于有人嘲讽以太坊“几乎不可能”实现真正的抗量子迁移。反观比特币，得益于其简单而弹性的UTXO+Script设计，只需通过新的输出类型软分叉，就可以逐步引入抗量子地址，让用户自愿迁移过渡，避免一次性硬分叉的系统性风险。

BIP-360：可选抗量子签名，引入量子博弈

面对量子威胁，比特币开发社区并未坐以待毙。2024年，由开发者Hunter Beast提出的BIP-360提案（又称P2QRH，意为“支付到抗量子哈希”）正式将抗量子签名引入了议事日程anduro.io。BIP-360核心思路是在比特币中增加新的地址类型，这些地址采用后量子密码学的签名算法（当前优先考虑Falcon，并备选CRYSTALS-Dilithium和SPHINCS+等）来取代易受量子攻击的ECDSA/Schnorr签名anduro.iogroups.google.com。换句话说，用户可以自愿选择生成一种“抗量子地址”，对应的UTXO需使用抗量子算法签名才能解锁。

为什么说BIP-360让比特币“引诱”量子计算加入博弈？这里有几层含义：

首先，BIP-360采用软分叉方式部署，可选而非强制。这意味着在量子计算真正成熟之前，绝大多数交易仍可继续使用原有签名算法，不平添负担；而有安全偏好的用户或机构可以提前迁移一部分资金到抗量子地址以高枕无忧。随着量子技术进展，逐步会有更多人选择这个选项，形成一个与量子威胁赛跑的过程。这种自愿迁移机制本身就是一种对量子黑客的诱导：网络主动暴露出一个“堡垒更坚固”的区域，鼓励守法用户往那里走，同时意味着留下的旧区域反而成为显眼的攻击目标和“诱饵”。

其次，BIP-360在算法选择和参数上充分考虑了区块链经济的承受力。起初提案曾讨论过一些前沿算法如SQIsign，但发现其验证开销高达ECDSA的15,000倍，若全网采用将使验证一块新区块从1秒暴涨到4小时，带来难以接受的性能瓶颈groups.google.com。最终的方案优选Falcon等NIST标准算法，它们签名体积较小、验证高效，可与当前区块大小和验证速度相容groups.google.com。例如Falcon-1024的签名约1.3KB、公钥1.7KB左右，这虽然比当前64字节的Schnorr签名大得多，但并非无法承受。通过配置灵活的安全级别（如重要交易才用Falcon-1024，一般小额用Falcon-512或普通Schnorr），比特币区块空间将被合理分配在安全性和费用之间。BIP-360精心设计了新的地址格式和见证结构，确保即便引入抗量子签名，区块验证和存储开销也在经济范围内，不会动摇挖矿和节点运行的成本平衡anduro.io。

最后也是最具前瞻性的一点，BIP-360为量子计算参与链上博弈打开了一扇门。通过提供抗量子和非抗量子地址并存的环境，比特币网络其实设置了一个对量子计算的挑战擂台：量子计算可以选择去攻击那些仍使用旧签名算法且价值巨大的UTXO，但同一时间，网络里的用户也在不断提升关键UTXO的签名强度来应对。量子计算不再是一个纯粹的外部敌人，而被巧妙地“请”进了系统，在规则内与用户和矿工互动。这为下一节将讨论的新经济模型奠定了基础——破解即挖矿的雏形由此孕育。

值得一提的是，BIP-360还提出了一个Taproot的量子安全补丁方案P2TRH，用哈希隐藏Taproot的公钥以弥补其“公钥长曝”缺陷groups.google.comgroups.google.com。因为现有的Taproot地址（见证v1）是直接以公钥生成地址，失去了UTXO模型隐藏公钥的优势，量子攻击者可以随时尝试破解Taproot资金。P2TRH通过将Taproot公钥再哈希一层，恢复“见证前隐藏公钥”的特性，代价是每笔此类输入增加8.25字节开销groups.google.com。这显示出比特币开发者未雨绸缪，连新升级的Taproot漏洞也在想办法弥补，使全局达到抗量子的结构性统一。

综上，BIP-360及相关提案不仅提供了技术方案，更释放出一种积极的信号：比特币正主动拥抱量子挑战，将其纳入规则之内。正如Anduro团队支持BIP-360时所言：“量子攻击的威胁严肃而迫近，我们不能坐等紧急关头才手忙脚乱。”anduro.ioanduro.io比特币社区选择了在危机到来前主动布局，以最小的代价换取最大的安全冗余和发展新契机。

“破解竞赛”经济模型：当量子成为新矿工

设想未来5-15年内，量子计算技术逐步成熟。在比特币网络中，可能会上演这样一幕令人惊叹的图景：量子计算矿工和抗量子验证者同时在线，围绕着尚未升级的老式UTXO展开一场你追我赶的“破解竞赛”。这将引发怎样的经济动力？我们大胆描绘一个后PoW时代的可能场景：

一方面，强大的量子计算机不再浪费算力去挖掘哈希谜题（传统PoW），而是直接瞄准那些“量子易攻”的UTXO，即尚使用老式ECDSA/Schnorr签名且公钥已暴露的地址。这些地址里的币对合法持有人来说如果迟迟未迁移到抗量子地址，实际上就变成了躺在链上的“悬赏”：谁能先算出私钥，谁就能转走这些币。在量子计算参与者眼中，这些币和早期比特币矿工眼中的区块奖励无异，都是凭借算力可竞争获取的收益。值得注意的是，根据分析，目前约有25%的比特币（按币量）处于公钥已暴露状态deloitte.com。随着时间推移，这个比例可能上升——除非持有人主动升级安全。这就像网络故意留出了一片“牧场”，让量子计算在其中竞相捕猎，以获得收益。量子攻击者之间形成竞争：更快的量子芯片、更好的算法意味着可以更早破解特定私钥，拿下那笔币。这几乎就是PoW的变体——过去矿工拼SHA-256算力抢区块奖励，未来量子矿工拼质因数分解/离散对数能力抢遗留UTXO。

另一方面，守护这片“牧场”的则是抗量子验证者和普通用户自身的防范行为。所谓抗量子验证者，可能是运行完整后量子节点或提供安全服务的专业机构。他们一方面帮助用户升级UTXO（例如提供一键迁移服务，把旧地址币转移到新PQ地址上，收取服务费），另一方面监测全网可疑交易。当量子攻击者尝试盗取某UTXO时，如果该UTXO持有者事先购买了“安全服务”，验证者可以抢先代为花费将币转移到更安全的地址（类似白帽黑客行为），或者提供更高级别签名升级以挫败攻击。总之，抗量子能力本身也成为一种商品，在市场上明码标价。你想让自己的币绝对安全？可以付费请量子安全服务团队定期轮换密钥、使用最高强度签名、监控链上异常。你的交易想确保不中途被截胡？可以支付更高矿工费甚至指定量子保险节点护送。在链上，一个根据签名难度和安全级别定价的市场逐渐形成：越高难度的签名（比如超长位的Falcon变种、多重签名方案结合等）需要支付越高的费用来存储和验证；反过来，这些费用补贴给保障网络安全的矿工/节点，激励他们投入更多资源提升抗量子能力。这种正反馈循环下，“安全”本身成为了新的经济激励。

如此一来，比特币生态迎来了“后挖矿时代”的转型：当区块补贴逐渐趋零，原本空缺的矿工激励由量子破解竞赛和安全服务市场所填补。量子计算加入竞争并非摧毁网络，反而扮演起类似矿工的角色，通过攻破薄弱环节来获得收益；而诚实的参与者则通过不断升级安全措施和支付安全费用来保护资产。这看似矛盾，却形成了动态平衡：正如生物进化中的“红后效应”，猎豹越快，羚羊也进化得更快，两者共同提升了系统的活力。

当然，这一模型中也充满戏剧性和讽刺意味——尤其当我们把眼光投向其他缺乏这种机制的公链。以太坊等账户制链若在量子时代陷入危机，很可能只能选择停机硬分叉、或者由中心化机构出面更换用户密钥，几乎无自动博弈的空间可言。而比特币网络则通过精妙的协议调整，把外部威胁内化为内部博弈，让市场机制去调节和应对。这种弹性与活力，正是比特币经久不衰的原因。

结语：危机催生新生，量子力量为我所用

当年互联网面对计算机病毒肆虐时，人们最终没有被动防守，而是发展出杀毒产业、安全协议，将病毒的威胁转化为推动网络更加健壮的动力。同样道理，比特币面对量子计算的冲击，并非只能筑高墙固步自封，而是选择了更具前瞻性的道路：拥抱威胁、化敌为友。通过提前布局抗量子基础设施（UTXO模型、SegWit扩展、PQ签名算法）、逐步推行BIP-360等方案，比特币正悄然改变游戏规则。在这个新规则中，量量对决、攻守博弈将上演全新篇章，网络安全不再是一成不变的盾牌，而是一套动态进化的生态系统。

或许若干年后回望，我们会发现量子计算并没有摧毁比特币，反而成就了比特币历史上的一次重大飞跃——开启了一个后工作量证明时代的新纪元。在这个纪元里，“破解就是新挖矿”不再只是戏谑之语，而成为链上真实上演的经济现象；“出售安全”也从附属服务变成每个节点和用户的日常考量。比特币将继续履行其角色：作为一个去中心化的、自我强化的金融体系，它有能力将任何挑战转化为自身进化的燃料。

正如BIP-360提案作者所言，这是一个“when 而非 if”的议题anduro.io。量子计算终将到来，而比特币已在主动邀请它参与一场精心设计的游戏。当量子计算机真的站上擂台，比特币早已不再是那个任人宰割的靶子，而更像是一位早已摆好阵势的棋手，静候对手入局。在这盘大棋中，没有永远的猎物，只有不断进化的猎人。比特币，会是那个始终笑到最后的“猎人”吗？让我们拭目以待。

How Strategy (MSTR) Built Their Capital Stack to Accelerate Bitcoin Accumulation

MicroStrategy—now operating as Strategy—has built the most aggressive Bitcoin treasury in the world. But its true innovation isn’t just holding Bitcoin. It’s in how it finances the accumulation of Bitcoin at scale without giving up control or diluting shareholder value.

The engine behind this? A meticulously designed capital stack—a multi-tiered structure of debt, preferred stock, and equity that appeals to different types of investors, each with unique risk, yield, and volatility preferences.

This is more than corporate finance—it’s a blueprint for Bitcoin-native capital formation.

What Is a Capital Stack?

A capital stack refers to the layers of capital a company uses to finance its operations and strategic goals. Each layer has its own return profile, risk level, and repayment priority in the event of liquidation.

Strategy’s capital stack is designed to do one thing exceptionally well: convert fiat capital into Bitcoin exposure—efficiently, at scale, and without compromise.

The Stack: Ordered by Priority

Strategy’s capital stack comprises five core instruments:

1. Convertible Notes
2. Strife Preferred Stock ($STRF)
3. Strike Preferred Stock ($STRK)
4. Stride Preferred Stock ($STRD)
5. Common Equity ($MSTR)

These layers are ranked from highest to lowest in repayment priority. What makes this structure unique is how each layer balances downside protection, yield, and Bitcoin exposure—offering institutional investors fixed-income alternatives with varying degrees of correlation to Bitcoin.

Strategy’s Capital Stack illustrated by Chris Millas

Convertible Notes: Senior Debt with Optional Upside

Strategy’s capital stack begins with convertible notes—senior unsecured debt that can convert into equity.

• Downside: Low risk, high priority in liquidation
• Upside: Modest unless converted
• Appeal: Institutional debt investors seeking protection with optional Bitcoin-adjacent upside

These notes were Strategy’s earliest fundraising tools, enabling the company to raise billions in low-interest environments to accumulate Bitcoin without issuing equity.

Strife ($STRF): Investment-Grade Yield

Strife is a perpetual preferred stock designed to mimic high-grade fixed income.

• 10% cumulative dividend, paid in cash
• $100 liquidation preference
• No conversion rights or Bitcoin upside
• Compounding penalties on unpaid dividends
• Low volatility, medium risk profile

Strife targets conservative capital—allocators who want predictable income without equity or crypto exposure. It’s senior to other preferreds and common stock, making it a high-quality fixed-income proxy built atop a Bitcoin treasury.

Strike ($STRK): Yield + Bitcoin Optionality

Strike is convertible preferred stock—bridging fixed income and equity upside.

• 8% cumulative dividend
• Convertible into $MSTR at $1,000 strike
• Paid in cash or Class A shares
• Bitcoin exposure via conversion option
• Medium volatility, low risk

Strike appeals to investors who want income with optional participation in Bitcoin upside. In bullish Bitcoin cycles, the conversion option becomes valuable—offering a hybrid between bond-like stability and equity-like potential.

Stride ($STRD): High Yield, High Risk

Stride is the most junior preferred—non-cumulative, perpetual stock issued with high yield and few protections.

• >10% dividend, only if declared
• No compounding, no conversion, no voting rights
• Highest relative risk among preferreds
• Liquidation priority above common equity, but below all others

Stride plays a crucial role. Its issuance improves the credit quality of Strife, adding a subordinate capital buffer beneath it—similar to how mezzanine debt protects senior tranches in structured finance.

Stride attracts yield-hungry investors, enabling Strategy to raise capital without compromising more senior layers.

Common Equity ($MSTR): Pure Bitcoin Beta

At the base is Strategy’s common equity—the most volatile, least protected, but highest potential instrument in the stack.

• Unlimited upside
• No dividend, no priority
• Full exposure to Bitcoin volatility
• Voting rights, long-term ownership

Common equity is for conviction-driven investors. Over the past four years, this layer has attracted capital from funds and individuals aligned with Strategy’s Bitcoin thesis—investors who want maximal upside from a corporate Bitcoin strategy.

The Big Picture: Saylor Is Targeting the Fixed Income Market

This isn’t just a financing mechanism—it’s a direct challenge to the $130 trillion global bond market.

By issuing instruments like $STRF, $STRK, and $STRD, Strategy is offering Bitcoin-adjacent yield vehicles that absorb demand from across the capital spectrum:

• Institutional investors seeking investment-grade yield
• Hedge funds chasing structured upside
• Yield hunters willing to go down the stack for returns

Each instrument behaves like a synthetic bond, yet all are backed by a Bitcoin accumulation engine.

As Director of Bitcoin Strategy at Metaplanet, Dylan LeClair put it: “Saylor is coming for the entire fixed income market.”

Rather than issue traditional bonds, Saylor is constructing a Bitcoin-native capital stack—one that unlocks liquidity without ever selling the underlying asset.

Why It Matters: A Model for Bitcoin Treasury Strategy

Strategy’s capital structure is more than innovation—it’s a financial operating system for any public company that wants to monetize Bitcoin’s rise while maintaining capital discipline.

Key takeaways:

• Every layer matches a specific investor need: From low-risk debt to speculative yield
• Capital flows in, Bitcoin stays put: Preserving treasury position while scaling
• No single instrument dominates: The stack is diversified by design
• Control is retained: Most securities are non-voting, non-convertible

For corporations serious about building a Bitcoin-native balance sheet, this is the playbook to study.

Saylor isn’t just stacking Bitcoin—he’s engineering the financial infrastructure for a monetary paradigm shift.

This article was originally published on aier.org

Even after eleven years experience, and a per Bitcoin price of nearly $20,000, the incredulous are still with us. I understand why. Bitcoin is not like other traditional financial assets.

Even describing it as an asset is misleading. It is not the same as a stock, as a payment system, or a money. It has features of all these but it is not identical to them.

What Bitcoin is depends on its use as a means of storing and porting value, which in turn rests of secure titles to ownership of a scarce good. Those without experience in the sector look at all of this and get frustrated that understanding why it is valuable is not so easy to grasp. 

In this article, I’m updating an analysis I wrote six years ago. It still holds up. For those who don’t want to slog through the entire article, my thesis is that Bitcoin’s value obtains from its underlying technology, which is an open-source ledger that keeps track of ownership rights and permits the transfer of these rights. Bitcoin managed to bundle its unit of account with a payment system that lives on the ledger. That’s its innovation and why it obtained a value and that value continues to rise. 

Consider the criticism offered by traditional gold advocates, who have, for decades, pushed the idea that sound money must be backed by something real, hard, and independently valuable. Bitcoin doesn’t qualify, right? Maybe it does. 

Bitcoin first emerged as a possible competitor to national, government-managed money in 2009. Satoshi Nakamoto’s white paper was released October 31, 2008. The structure and language of this paper sent the message: This currency is for computer technicians, not economists nor political pundits. The paper’s circulation was limited; novices who read it were mystified. 

But the lack of interest didn’t stop history from moving forward. Two months later, those who were paying attention saw the emergence of the “Genesis Block,” the first group of bitcoins generated through Nakamoto’s concept of a distributed ledger that lived on any computer node in the world that wanted to host it.

Here we are all these years later and a single bitcoin trades at $18,500. The currency is held and accepted by many thousands of institutions, both online and offline. Its payment system is very popular in poor countries without vast banking infrastructures but also in developed countries. And major institutions—including the Federal Reserve, the OECD, the World Bank, and major investment houses—are paying respectful attention and weaving blockchain technology into their operations.

Enthusiasts, who are found in every country, say that its exchange value will soar even more in the future because its supply is strictly limited and it provides a system vastly superior to government money. Bitcoin is transferred between individuals without a third party. It is relatively low-cost to exchange. It has a predictable supply. It is durable, fungible, and divisible: all crucial features of money. It creates a monetary system that doesn’t depend on trust and identity, much less on central banks and government. It is a new system for the digital age.

Hard lessons for hard money

To those educated in the “hard money” tradition, the whole idea has been a serious challenge. Speaking for myself, I had been reading about bitcoin for two years before I came anywhere close to understanding it. There was just something about the whole idea that bugged me. You can’t make money out of nothing, much less out of computer code. Why does it have value then? There must be something amiss. This is not how we expected money to be reformed.

There’s the problem: our expectations. We should have been paying closer attention to Ludwig von Mises’ theory of money’s origins—not to what we think he wrote, but to what he actually did write. 

In 1912, Mises released The Theory of Money and Credit. It was a huge hit in Europe when it came out in German, and it was translated into English. While covering every aspect of money, his core contribution was in tracing the value and price of money—and not just money itself—to its origins. That is, he explained how money gets its price in terms of the goods and services it obtains. He later called this process the “regression theorem,” and as it turns out, bitcoin satisfies the conditions of the theorem.

Mises’ teacher, Carl Menger, demonstrated that money itself originates from the market—not from the State and not from social contract. It emerges gradually as monetary entrepreneurs seek out an ideal form of commodity for indirect exchange. Instead of merely bartering with each other, people acquire a good not to consume, but to trade. That good becomes money, the most marketable commodity.

But Mises added that the value of money traces backward in time to its value as a bartered commodity. Mises said that this is the only way money can have value.

The theory of the value of money as such can trace back the objective exchange value of money only to that point where it ceases to be the value of money and becomes merely the value of a commodity…. If in this way we continually go farther and farther back we must eventually arrive at a point where we no longer find any component in the objective exchange value of money that arises from valuations based on the function of money as a common medium of exchange; where the value of money is nothing other than the value of an object that is useful in some other way than as money…. Before it was usual to acquire goods in the market, not for personal consumption, but simply in order to exchange them again for the goods that were really wanted, each individual commodity was only accredited with that value given by the subjective valuations based on its direct utility.

Mises’ explanation solved a major problem that had long mystified economists. It is a narrative of conjectural history, and yet it makes perfect sense. Would salt have become money had it otherwise been completely useless? Would beaver pelts have obtained monetary value had they not been useful for clothing? Would silver or gold have had money value if they had no value as commodities first? The answer in all cases of monetary history is clearly no. The initial value of money, before it becomes widely traded as money, originates in its direct utility. It’s an explanation that is demonstrated through historical reconstruction. That’s Mises’ regression theorem.

Bitcoin’s Use Value

At first glance, bitcoin would seem to be an exception. You can’t use a bitcoin for anything other than money. It can’t be worn as jewelry. You can’t make a machine out of it. You can’t eat it or even decorate with it. Its value is only realized as a unit that facilitates indirect exchange. And yet, bitcoin already is money. It’s used every day. You can see the exchanges in real time. It’s not a myth. It’s the real deal.

It might seem like we have to choose. Is Mises wrong? Maybe we have to toss out his whole theory. Or maybe his point was purely historical and doesn’t apply in the future of a digital age. Or maybe his regression theorem is proof that bitcoin is just an empty mania with no staying power, because it can’t be reduced to its value as a useful commodity.

And yet, you don’t have to resort to complicated monetary theory in order to understand the sense of alarm surrounding bitcoin. Many people, as I did, just have a feeling of uneasiness about a money that has no basis in anything physical. Sure, you can print out a bitcoin on a piece of paper, but having a paper with a QR code or a public key is not enough to relieve that sense of unease.

How can we resolve this problem? In my own mind, I toyed with the issue for more than a year. It puzzled me. I wondered if Mises’ insight applied only in a pre-digital age. I followed the speculations online that the value of bitcoin would be zero but for the national currencies into which it is converted. Perhaps the demand for bitcoin overcame the demands of Mises’ scenario because of a desperate need for something other than the dollar.

As time passed—and I read the work of Konrad Graf, Peter Surda, and Daniel Krawisz—finally the resolution came. Bitcoin is both a payment system and a money. The payment system is the source of value, while the accounting unit merely expresses that value in terms of price. The unity of money and payment is its most unusual feature, and the one that most commentators have had trouble wrapping their heads around.

We are all used to thinking of currency as separate from payment systems. This thinking is a reflection of the technological limitations of history. There is the dollar and there are credit cards. There is the euro and there is PayPal. There is the yen and there are wire services. In each case, money transfer relies on third-party service providers. In order to use them, you need to establish what is called a “trust relationship” with them, which is to say that the institution arranging the deal has to believe that you are going to pay.

This wedge between money and payment has always been with us, except for the case of physical proximity.

If I give you a dollar for your pizza slice, there is no third party. But payment systems, third parties, and trust relationships become necessary once you leave geographic proximity. That’s when companies like Visa and institutions like banks become indispensable. They are the application that makes the monetary software do what you want it to do.

The hitch is that

MARA Announces Over $100 Million in Bitcoin Mined in May 2025

Today, MARA Holdings, Inc. (NASDAQ: MARA) reported a record high month of bitcoin production in May 2025, mining 950 BTC worth over $100 million at the time of writing. A 35% increase from April and the highest monthly output since the April 2024 halving event. MARA did not sell any bitcoin in May.

— Bitcoin Magazine (@BitcoinMagazine) June 3, 2025

“May was a record-breaking month for MARA with 282 blocks won, a 38% increase over April and a new monthly high,” said the Chairman and CEO of MARA Fred Thiel. “Our total bitcoin holdings surpassed 49,000 BTC during May and the 950 bitcoin produced were the most since the halving event in April 2024.”

The company mined 282 blocks during the month, a 38% rise over the previous month, and now holds 49,179 BTC, worth roughly $5.23 billion at the time of writing.

“Our fully integrated tech stack is a key differentiator, and MARA Pool is the only self-owned and operated mining pool among public miners, offering greater control and efficiency,” stated Thiel. “Operating our pool means no fees to external operators and retention of the full value of block rewards. Production in May also benefitted from block reward luck. Since launch, MARA Pool’s block reward luck has outperformed the network average by over 10%, contributing to our industry-leading block production.”

Operational efficiency also improved, with energized hashrate rising 2% from 57.3 EH/s to 58.3 EH/s. MARA’s average daily bitcoin production hit 30.7 BTC, which is 31% more than the last month from April.

“We remain laser-focused on transforming MARA into a vertically integrated digital energy and infrastructure company,” commented Thiel. “We believe this model gives us tighter operational control, improves cost-efficiency, and makes us more resilient to shifts in the broader economy.”

Earlier this month, on May 8, MARA released its first quarter 2025 earnings, posting 213.9 million dollars in revenue. A 30 percent increase over the same period last year. The company’s bitcoin holdings surged 174 percent year over year, rising from 17,320 BTC to 47,531 BTC as of March 31, with an estimated value of 3.9 billion dollars at the time. In Q1, MARA mined 2,286 BTC and acquired an additional 340 BTC. Operational performance also strengthened, with energized hashrate nearly doubling from 27.8 EH/s to 54.3 EH/s, and cost per petahash per day improving by 25 percent.

Akhenaten (originally named Amenhotep IV) was a pharaoh of ancient Egypt known for radically transforming Egyptian religion, art, and culture. He is most famous for promoting the worship of one god—Aten, the sun disk—marking one of the earliest recorded movements toward monotheism.

Early Life and Rise to Power of pharaoh Akhenaten.

The Birth Name was  Amenhotep IV, and he was born Around 1380 BCE. By  Pharaoh Amenhotep III, and the mother Likely Queen Tiye. He grew up and married a Wife, Nefertiti, one of Egypt's most iconic queens. He have children, Including daughters and likely the father of Tutankhamun (King Tut).

Amenhotep IV ascended the throne around 1353 BCE, succeeding his father, a powerful and prosperous pharaoh, and there was a Religious Revolution.

A Shift Toward Monotheism

Around his 5th regnal year, Amenhotep IV changed his name to Akhenaten, meaning "Effective for Aten".

He abandoned the traditional Egyptian pantheon, especially the powerful god Amun, and elevated Aten as the sole god.

This was a dramatic break from Egypt's deeply rooted polytheistic religion.

The capital city Akhetaten (Modern-day Amarna). Akhenaten moved the capital from Thebes to a new city he built from scratch: Akhetaten (Horizon of Aten).

The city was dedicated entirely to the Aten religion and became a center of art, culture, and politics.

Nefertiti was not just a queen but a powerful co-ruler. Some theories suggest she may have ruled independently for a time after Akhenaten’s death (possibly as Neferneferuaten).

They had at least six daughters. The identity of Akhenaten's sons is debated, but Tutankhamun is widely believed to be his son, possibly by a secondary wife.

Decline and Death

Akhenaten died around 1336 BCE after a 17-year reign.

After his death, his successors (including Tutankhamun) restored traditional religion, abandoned Atenism, and moved the capital back to Thebes.

His monuments were defaced, and his name was erased from king lists, a process known as damnatio memoriae (damnation of memory).

Legacy

Akhenaten is remembered as:

A visionary who introduced monotheism before it appeared in other cultures.

A heretic who defied over a thousand years of religious tradition.

A reformer whose bold changes caused cultural upheaval.

His religious revolution was short-lived, but modern historians and archaeologists regard him as one of the most fascinating and controversial figures in ancient history.

The reasons why Pharaoh Akhenaten introduced monotheism, the worship of Aten, the sun disk, as the one true god are still debated by historians, but several key political, religious, personal, and philosophical factors likely contributed.

✅ Main Reasons Why Akhenaten Introduced Monotheism

• Religious Reform: Belief in a Universal Power

Akhenaten may have genuinely believed in Aten as the supreme creator and life-giver.

The sun was already important in Egyptian religion (Ra, Amun-Ra), but Akhenaten stripped away all personification, choosing the sun's disk (Aten) as a pure, abstract symbol of divine power.

He saw Aten as omnipresent, providing light and life to everything and everyone equally.

• Political Motivation: Weaken the Power of the Priests

The priesthood of Amun at Thebes had become extremely wealthy and powerful, almost a state within a state. By elevating Aten and banning Amun's worship, Akhenaten dismantled the influence of the Amun priests and centralized religious power in his own hands. He made himself the sole mediator between Aten and the people, increasing royal control.

• Personal Vision and Identity

Akhenaten may have had a personal religious experience or conviction that shaped his devotion to Aten.

His new name, “Akhenaten,” meaning “Effective for the Aten,” reflects a deep, personal connection to this god.

He often depicted himself and his family in direct contact with Aten, showing a highly intimate and unique belief system.

• Philosophical and Artistic Shift

Akhenaten's reign saw a revolution in art, emphasizing naturalism, emotion, and individuality.

This change in thinking may reflect a broader philosophical shift toward a more abstract and spiritual understanding of the divine unified in Aten.

Atenism removed the idea of gods with human forms, replacing them with a universal force (the sun's light).

• Reaction Against Religious Corruption or Complexity

Traditional Egyptian religion had hundreds of gods, rituals, and temple hierarchies.

Akhenaten may have seen the system as corrupt, ritualistic, and too complex for ordinary people.

Atenism was simple, focused, and accessible, with the sun’s light reaching everyone equally.

• Political Instability or Health Issues (Speculative)

Some theories suggest Akhenaten’s appearance (depicted with elongated head, wide hips, etc.) may reflect a genetic disorder (e.g., Marfan syndrome or Froehlich's syndrome).

If he was sickly, he may have been drawn to religious introspection or spiritual reform.

Others suggest that political instability or unrest during his early reign may have motivated a bold unifying reform.

Summary

Akhenaten’s monotheism was unprecedented in Egypt’s long religious history. Whether he was a spiritual visionary, a political tactician, or both, his religious revolution stands out as one of the most dramatic and controversial in ancient history.

Just calling it Open is not enough - Herausforderungen öffentlicher Bildungsinfrastrukturen und wie Nostr helfen könnte

Ich möchte gerne mit euch teilen, an welchen Konzepten ich arbeite, um die öffentliche Bildungsinfrastruktur mit Hilfe von Nostr zugänglicher und offener zu gestalten. Ich arbeite im Bereich öffentlicher Bildungsinfrastrukturen, besonders im Feld von Open Educational Resources (#OER). OER sind offen lizenzierte Bildungsmaterialien, die mit einer offenen Lizenz, meist einer Creative Commons Lizenz, versehen sind (CC-0, CC-BY, CC-BY-SA). Durch die klare und offene Lizenzierung ist es leicht möglich, die Lernmaterialien auf die individuellen Bedarfe anzupassen, sie zu verbessern und sie erneut zu veröffentlichen.

Seit vielen Jahren wird einerseits die Entwicklung freier Bildungsmaterialien gefördert, andererseits werden Plattformen, insbesondere Repositorien gefördert, die diese Materialien verfügbar machen sollen. Denn irgendwo müssen diese Materialien zur Verfügung gestellt werden, damit sie auch gefunden werden können.

Das klappt allerdings nur so mittelgut.

Herausforderungen

Nach vielen Jahren Förderung kann die einfache Frage: "Wo kann ich denn mein OER-Material bereitstellen" nicht einfach beantwortet werden. Es gibt Services, bei denen ich mein OER hochladen kann, jedoch bleibt es dann eingeschlossen in dieser Plattform und wird nicht auf anderen Plattformen auffindbar. Außerdem sind diese Services häufig an bestimmte Bildungskontexte gebunden oder geben Content erst nach einer Qualitätsprüfung frei. Dies führt dazu, dass ein einfaches und gleichzeitig öffentliches Teilen nicht möglich ist.

Diese und weitere Herausforderungen haben ihren Ursprung darin, dass Service und Infrastruktur in der Architektur öffentlichen Bildungsarchitektur ungünstig vermischt werden. Als Infrastruktur verstehe ich hier die Bereitstellung einer öffentlichen und offen zugänglichen Bildungsinfrastruktur, auf der Daten ausgetauscht, also bereitgestellt und konsumiert werden können. Jedoch existiert eine solche Infrstruktur momentan nicht unabhängig von den Services, die auf ihr betrieben werden. Infrastrukturbetreiber sind momentan gleichzeitig immer Servicebetreiber. Da sie aber die Hand darüber haben wollen, was genau in ihrem Service passiert (verständlich), schränken sie den Zugang zu ihrer Infrastruktur mit ein, was dazu führt, dass sie Lock-In Mechanismen großer Medienplattformen in der kleinen öffentlichen Bildungsinfrastruktur replizieren.

Es ist in etwas so, als würde jeder Autobauer auch gleichzeitig die Straßen für seine Fahrzeuge bauen. Aber halt nur für seine Autos.

Anhand einiger beispielhafter Services, die bestehende Plattformen auf ihren Infrastrukturen anbieten, möchte ich die Herausforderungen aufzeigen, die ich im aktuellen Architekturkonzept sehe:

• Upload von Bildungsmaterial
• Kuration: Zusammenstellung von Listen, Annotation mit Metadaten
• Crawling, Indexierung und Suche
• Plattfformübergreifende Kollaboration in Communities -> Beispiel: Qualitätssicherung (was auch immer das genau bedeutet)
• KI- Services -> Beispiel: KI generierte Metadaten für BiIdungsmaterial

Material Upload

Der Service "Material-Upload" oder das Mitteilen eines Links zu einem Bildungsmaterial wird von verschiedenen OER-Pattformen bereitgestellt (wirlernenonline.de, oersi.org, mundo.schule).

Dies bedeutet konkret: Wenn ich bei einer der Plattformen Content hochlade, verbleibt der Content in der Regel auch dort und wird nicht mit den anderen Plattformen geteilt. Das Resultat für die User: Entweder muss ich mich überall anmelden und dort mein Material hochladen (führt zu Duplikaten) oder damit leben, dass eben nur die Nutzer:innen der jeweiligen Plattform meinen Content finden können.

Der "Open Educational Resource Search Index" (OERSI) geht diese Herausforderung an, indem die Metadaten zu den Bildungsmaterialien verschiedener Plattformen in einem Index bereitgestellt werden. Dieser Index ist wiederum öffentlich zugänglich, sodass Plattformen darüber auch Metadaten anderer Plattformen konsumieren können. Das ist schon sehr gut. Jedoch funktioniert das nur für Plattformen, die der OERSI indexiert und für alle anderen nicht. Der OERSI ist auf den Hochschulbereich fokussiert, d.h. andere Bildungskontexte werden hier ausgeschlossen. Der Ansatz für jeden Bildungsbereich einen passenden "OERSI" daneben zustellen skaliert und schlecht und es bleibt die Herausforderung bestehen, dass für jede Quelle, die indexiert werden soll, ein entsprechender Importer/Crawler geschrieben werden muss.

Dieser Ansatz (Pull-Ansatz) rennt den Materialien hinterher.

Es gibt jedoch noch mehr Einschränkungen: Die Plattformen haben sich jeweils auf spezifische Bildungskontexte spezialisiert. D.h. auf die Fragen: Wo kann ich denn mein OER bereitstellen, muss immer erst die Gegenfrage: "Für welchen Bildungsbereich denn?" beantwortet werden. Wenn dieser außerhalb des allgemeinbildendenden Bereichs oder außerhalb der Hochschule liegt, geschweige denn außerhalb des institutionellen Bildungsrahmens, wird es schon sehr, sehr dünn. Kurzum:

• Es ist nicht einfach möglich OER bereitzustellen, sodass es auch auf verschiedenen Plattformen gefunden werden kann.

Kuration

Unter Kuration verstehe ich hier die Zusammenstellung von Content in Listen oder Sammlungs ähnlicher Form sowie die Annotation dieser Sammlungen oder des Contents mit Metadaten.

Einige Plattformen bieten die Möglichkeit an, Content in Listen einzuordnen. Diese Listen sind jedoch nicht portabel. Die Liste, die ich auf Plattform A erstelle, lässt sich nicht auf Plattform B importieren. Das wäre aber schön, denn so könnten die Listen leichter auf anderen Plattformen erweitert oder sogar kollaborativ gestaltet werden, andererseits werden Lock-In-Effekte zu vermieden.

Bei der Annotation mit Metadaten treten verschiedene zentralisierende Faktoren auf. In der momentanen Praxis werden die Metadaten meist zum Zeitpunkt der Contentbereitstellung festgelegt. Meist durch eine Person oder Redaktion, bisweilen mit Unterstützung von KI-Services, die bei der Metadateneingabe unterstützen. Wie aber zusätzliche eigene Metadaten ergänzen? Wie mitteilen, dass dieses Material nicht nur für Biologie, sondern auch für Sport in Thema XY super einsetzbar wäre? Die momentanen Ansätze können diese Anforderung nicht erfüllen. Sie nutzen die Kompetenz und das Potential ihrer User nicht.

• Es gibt keine interoperablen Sammlungen
• Metadaten-Annotation ist zentralisiert
• User können keine eigenen Metadaten hinzufügen

Crawling, Indexierung und Suche

Da die Nutzer:innen nicht viele verschiedene Plattformen und Webseiten besuchen wollen, um dort nach passendem Content zu suchen, crawlen die "großen" OER-Aggregatoren diese, um die Metadaten des Contents zu indexieren. Über verschiedene Schnittstellen oder gerne auch mal über das rohe HTML. Letztere Crawler sind sehr aufwändig zu schreiben, fehleranfällig und gehen bei Design-Anpassungen der Webseite schnell kaputt, erstere sind etwas stabiler, solange sich die Schnittstelle nicht ändert. Durch den Einsatz des Allgemeinen Metadatenprofils für Bildungsressourcen (AMB) hat sich die Situation etwas verbessert. Einige Plattformen bieten jetzt eine Sitemap an, die Links zu Bildungsmaterial enthalten, die wiederum eingebettet script-tags vom Typ application/ld+json enthalten, sodass die Metadaten von dort importiert werden können.

Beispiel: e-teaching.org bietet hier eine Sitemap für ihre OER an: https://e-teaching.org/oer-sitemap.xml und auf den jeweiligen Seiten findet sich ein entsprechendes script-Tag.

Das ist schon viel besser, aber da geht noch mehr:

Zunächst ist dieser Ansatz nur für Plattformen und Akteure praktikabel, die über IT-Ressourcen verfügen, um entsprechende Funktionalitäten bei sich einbauen zu können. Lehrende können dies nicht einfach auf ihrem privaten Blog oder ähnliches umsetzen. Zum anderen besteht immer noch ein Discovery Problem. Ich muss nach wie vor wissen, wo ich suchen muss. Ich muss die Sitemaps kennen, sonst finde ich nichts. Statt eines Ansatzes, bei dem Akteure eigenständig mitteilen können, dass sie neuen Content haben (Push-Ansatz), verfolgen wir derzeit einen Ansatz, bei dem jede Plattform für sich Content im Pull-Verfahren akquiriert. Dies führt an vielen Stellen zu Doppelarbeiten, ist ineffizient (mehrere Personen bauen genau die gleichen Crawler, aber halt immer für ihre Plattform) und schliesst vor allem kleine Akteure aus (lohnt es sich einen Crawler zu programmieren, wenn die Webseite "nur" 50 Materialien bereitstellt?).

Anstatt erschlossene Daten zu teilen, arbeiten die Plattformen für sich oder stellen es höchstens wieder hinter eigenen (offenen oder geschlossenen) Schnittstellen bereit. Das ist wohl nicht das, was wir uns unter einer offenen und kollaborativen Gemeinschaft vorstellen, oder?

Bei der Suche stehen wir vor ähnlichen Herausforderungen, wie bereits oben geschildert. Obwohl verschiedene OER-Aggregatoren in Form von Repositorien oder Referatorien bereits viele der "kleineren" Plattformen indexieren und somit eine übergreifende Suche anbieten, ist es nicht möglich, diese Aggregatoren gemeinsam zu durchsuchen. Dies führt im Endeffekt dazu, dass die User wieder verschiedene Plattformen ansteuern müssen, wenn sie den gesamten OER-Fundus durchsuchen wollen.

• An vielen Stellen wird Content doppelt erschlossen, aber immer für die eigene Plattform
• Es gibt keinen geteilten Datenraum, in den Akteure Content "pushen" können
• Es gibt keine plattformübergreifenden Suchmöglichkeiten

Plattformübergreifende Kollaboration

Das wäre schön, oder? Mir ist schleierhaft, wie #OEP (Open Educational Practices, genaue Definition durch die Community steht noch aus) ohne funktionieren soll. Aber es gibt meines Wissens nach nicht mal Ansätze, wie das technisch umgesetzt werden soll (oder doch? let me hear).

Ein Szenario für solche plattformübergreifende Kollaboration könnte Qualitätssicherung sein. Gesetzt, dass sich zwei Plattformen / Communities auf etwas verständigt haben, dass sie als "Qualität" bezeichnen, wie aber dieses Gütesiegel nun an den Content bringen?

Plattform A: Na, dann kommt doch alle zu uns. Hier können wir das machen und dann hängt auch ein schönes Badge an den Materialien.

Plattform B: Ja, aber dann hängt es ja nicht an unseren Materialien. Außerdem wollen/müssen wir bei uns arbeiten, weil welche Existenzberechtigung hat denn meine Plattform noch, wenn wir alles bei dir machen?

• Obwohl nun #OEP in aller Munde sind, gibt es keine technischen Ansätze, wie (plattformübergreifende) Kollaboration technisch abgebildet werden kann

KI-Services

Was ist heute schon komplett ohne das Thema KI zu erwähnen? Mindestens für den nächsten Förderantrag muss auch irgendetwas mit KI gemacht werden...

Verschiedene Projekte erarbeiten hilfreiche und beeindruckende KI-Services. Beispielsweise, um die Annotation von Content mit Metadaten zu erleichtern, Metadaten automatisch hinzuzufügen, Content zu bestimmten Themen zu finden oder (halb-)automatisch zu Sammlungen hinzuzufügen. Aber (vielleicht habt ihr es schon erraten): Funktioniert halt nur auf der eigenen Plattform. Vermutlich, weil die Services nah am plattformeigenen Datenmodell entwickelt werden. Und da die Daten dieses Silo nicht verlassen, passt das schon. Das führt dazu, dass an mehreren Stellen die gleichen Services doppelt entwickelt werden.

• KI-Services funktionieren oft nur auf der Plattform für die sie entwickelt werden

Zusammenfassung der Probleme

Wir machen übrigens vieles schon sehr gut (Einsatz des AMB, Offene Bidungsmaterialien, wir haben eine großartige Community) und jetzt müssen wir halt weiter gehen.

(Die OER-Metadatengruppe, die das Allgemeine Metadatenprofil für Bildungsressourcen (AMB) entwickelt hat, bekommt für ihre Arbeit keine direkte Förderung. Gleichzeitig ist sie eine zentrale Anlaufstelle für alle, die mit Metadaten in offenen Bildungsinfrastukturen hantieren und das Metadatenprofil ist eines der wenigen Applikationsprofile, das öffentlich einsehbar, gut dokumentiert ist und Validierungsmöglichkeiten bietet.)

Betrachten wir die gesamten Plattformen und die beschriebenen Herausforderungen aus der Vogelperspektive, so lassen sich drei ineinander verschränkte Kernbestandteile unterscheiden, die helfen, die beschriebenen Probleme besser zu verstehen:

• User
• Service
• Daten

User: Auf (fast) allen Plattformen agieren User. Sie laden Material hoch, annotieren mit Metadaten, sind in einer Community, suchen Content usw. Egal, ob sie sich einloggen können/müssen, irgendetwas bieten wir unseren Usern an, damit sie daraus hoffentlich Mehrwerte ziehen

Service: Das ist dieses irgendetwas. Die "Webseite", die Oberfläche, das, wo der User klicken und etwas tun kann. Es ist das, was den Daten oft eine "visuelle" Form gibt. Der Service ist der Mittler, das Interface zwischen User und Daten. Mithilfe des Services lassen sich Daten erzeugen, verändern oder entfernen (Es gibt natürlich auch viele nicht-visuelle Services, die Interaktion mit Daten ermöglichen, aber für die meisten normalen Menschen, gibt es irgendwo was zu klicken).

Daten: Die Informationen in strukturierter maschinenlesbarer Form, die dem User in gerenderter Form durch einen Service Mehrwerte bieten können. Ungerenderte Daten können wir schwieirg erfassen (wir sind ja nicht Neo). Das können entweder die Metadaten zu Bildungmaterialien sein, die Materialien selbst, Profilinformationen, Materialsammlungen o.ä.

Meines Erachtens nach haben viele der oben beschriebenen Herausforderungen ihren Ursprung darin, dass die drei Kernbestandteile User, Service, Daten ungünstig miteinander verbunden wurden. Was kein Vorwurf sein soll, denn das ist genau die Art und Weise, wie die letzten Jahre (Jahrzehnte?) Plattformen immer gebaut wurden:

• User, Service und Daten werden in einer Plattform gebündelt

Das heisst durch meinen Service agieren die User mit den Daten und ich kann sicherstellen, dass in meiner kleinen Welt alles gut miteinander funktioniert. Sinnvoll, wenn ich Microsoft, Facebook, X oder ähnliches bin, weil mein Geschäftsmodell genau darin liegt: User einschließen (lock-in), ihnen die Hohheit über ihren Content nehmen (oder kannst du deine Facebook Posts zu X migrieren?) und nach Möglichkeit nicht wieder rauslassen.

Aber unsere Projekte sind öffentlich. Das sind nicht die Mechanismen, die wir replizieren sollten. Also was nun?

Bildungsinfrasstrukturen auf Basis des Nostr-Protokolls

Nostr

Eine pseudonyme Person mit dem Namen "fiatjaf" hat 2019 ein Konzept für ein Social Media Protokoll "Nostr - Notes and Other Stuff Transmitted By Relays" wie folgt beschrieben:

It does not rely on any trusted central server, hence it is resilient, it is based on cryptographic keys and signatures, so it is tamperproof, it does not rely on P2P techniques, therefore it works.

Fiatjaf, 2019

Die Kernbestandsteile des Protokolls bestehen aus:

• JSON -> Datenformat
• SHA256 & Schnorr -> Kryptographie
• Websocket -> Datenaustausch

Und funktionieren tut es so:

User besitzen ein "Schlüsselpaar": einen privaten Schlüssel (den behälst du für dich, nur für dich) und einen öffentlichen Schlüssel, den kannst du herumzeigen, das ist deine öffentliche Identität. Damit sagst du anderen Usern: Hier schau mal, das bin ich. Die beiden Schlüssel hängen dabei auf eine "magische" (kryptografische) Weise zusammen: Der öffentliche Schlüssel lässt sich aus dem privaten Schlüssel generieren, jedoch nicht andersherum. D.h. falls du deinen öffentlichen Schlüssel verlierst: Kein Problem, der lässt sich immer wieder herstellen. Wenn du deinen privaten Schlüssel verlierst: Pech gehabt, es ist faktisch unmöglich, diesen wieder herzustellen.

Die Schlüsselmagie geht jedoch noch weiter: Du kannst mit deinem privaten Schlüssel "Nachrichten" signieren, also wie unterschreiben. Diese Unterschrift, die du mit Hilfe des privaten Schlüssels erstellst, hat eine magische Eigenschaft: Jeder kann mithilfe der Signatur und deinem öffentlichen* Schlüssel nachprüfen, dass nur die Person, die auch den privaten Schlüssel zu diesem öffentlichen Schlüssel besitzt, diese Nachricht unterschrieben haben kann. Magisch, richtig? Verstehst du nicht komplett? Nicht schlimm, du benutzt es bereits vermutlich, ohne dass du es merkst. Das ist keine fancy neue Technologie, sondern gut abgehangen und breit im Einsatz.

Merke: User besitzen ein Schlüsselpaar und können damit Nachrichten signieren.

Dann gibt es noch die Services. Services funktionieren im Grunde wie bereits oben beschrieben. Durch sie interagieren die User mit Daten. Aber bei Nostr ist es ein kleines bisschen anders als sonst, denn: Die Daten "leben" nicht in den Services. Aber wo dann?

Wenn ein User einen Datensatz erstellt, verändert oder entfernen möchte, wird dieses "Event" (so nennen wir das bei Nostr) mit deinem privaten Schlüssel signiert (damit ist für alle klar, nur du kannst das gemacht haben) und dann mehrere "Relays" gesendet. Das sind die Orte, wo die Daten gehalten werden. Wenn ein User sich in einen Service einloggt, dann holt sich der Service die Daten, die er braucht von diesen Relays. User, Service und Daten sind also entkoppelt. Der User könnte zu einem anderen Service wechseln und sich dieseleben Daten von den Relays holen. Keine Lock-In Möglichkeiten.

Merke: User, Service und Daten sind entkoppelt.

Zuletzt gibt es noch die Relays. Relays sind Orte. Es sind die Orte, zu denen die Events, also die Daten der User, ihre Interaktionen, gesendet und von denen sie angefragt werden. Sie sind sowas wie das Backend von Nostr, allerdings tun sie nicht viel mehr als das: Events annehmen, Events verteilen. Je nach Konfiguration dürfen nur bestimmte User auf ein Relay schreiben oder davon lesen.

Das Protokoll ist von seinem Grunddesign auf Offenheit und Interoperabilität ausgelegt. Keine Registrierung ist nötig, sondern nur Schlüsselpaare. Durch kryptografische Verfahren kann dennoch die Authentizitität eines Events sichergestellt werden, da nur die Inhaberin des jeweiligen Schlüsselpaares dieses Event so erstellen konnte. Die Relays sorgen dafür die Daten an die gewünschten Stellen zu bringen und da wir mehr als nur eines benutzen, haben wir eine gewisse Ausfallsicherheit. Da die Daten nur aus signierten JSON-Schnipseln bestehen, können wir sie leicht an einen anderen Ort kopieren, im Falle eines Ausfalls. Durch die Signaturen ist wiederum sichergestellt, dass zwischendurch keine Veränderungen an den Daten vorgenommen wurden.

Beispiel: Ein Nostr Event

Hier ein kleiner technischer Exkurs, der beschreibt, wie Nostr Events strukturiert sind. Falls dich die technischen Details nicht so interessieren, überspringe diesen Abschnitt ruhig.

Jedes Nostr Event besitzt die gleiche Grundstruktur mit den Attributen:

• id: Der Hash des Events
• pubkey: Der Pubkey des Urhebers des Events
• created_at: Der Zeitstempel des Events
• kind: Der Typ des Events
• tags: Zusätzliche Metadaten für das Event können in diesem Array hinterlegt werden
• content: Der textuelle Inhalt eines Events
• sig: Die Signatur des Events, um die Integrität der Daten zu überprüfen

json { "id": <32-bytes lowercase hex-encoded sha256 of the serialized event data>, "pubkey": <32-bytes lowercase hex-encoded public key of the event creator>, "created_at": <unix timestamp in seconds>, "kind": <integer between 0 and 65535>, "tags": [ [<arbitrary string>...], // ... ], "content": <arbitrary string>, "sig": <64-bytes lowercase hex of the signature of the sha256 hash of the serialized event data, which is the same as the "id" field> }

Die verwendeten Eventtypen sowie die existierenden Spezifikationen lassen sich unter https://github.com/nostr-protocol/nips/ einsehen.

Wichtig ist auch: Du kannst einfach anfangen, Anwendungen zu entwickeln. Die Relays werden alle Events akzeptieren, die dem o.g. Schema folgen. Du musst also niemanden um Erlaubnis fragen oder warten, bis deine Spezifikation akzeptiert und hinzugefügt wurde.

You can just build things.

Exkurs: Nostr für Binärdaten - Blossom

Ja, aber... das ist doch nur für textbasierte Daten geeignet? Was ist denn mit den Binärdaten (Bilder, Videos, PDFs, etc)

Diese Daten sind oft recht groß und es wurde sich auf das Best-Practice geeignet, diese Daten nicht auf Relays abzulegen, sondern einen besser geeigneten Publikationsmechanismus für diese Datentypen zu finden. Der Ansatz wird als "Blossom - Blobs stored simply on mediaservers" bezeichnet und ist recht unkompliziert.

Blossom Server (nichts anderes als simple Medienserver) nutzen Nostr Schlüsselpaare zur Verwaltung Identitäten und zum Signieren von Events. Die Blobs werden über ihren sha256 Hash identifiziert. Blossom definiert einige standardisierte Endpunkte, die beschreiben wie Medien hochgeladen werden können, wie sie konsumiert werden können usw.

Die Details, wie Authorisierung und die jeweiligen Endpunkte funktionieren, werden in der genannten Spezifikation beschrieben.

Nostr 🤝 Öffentliche Bildungsinfrastrukturen

Wie könnten Herausforderungen gelöst werden, wenn wir Nostr als Basis für die öffentliche Bildungsinfrastruktur einsetzen?

Material-Upload

• Es ist nicht einfach möglich OER bereitzustellen, sodass es auch auf verschiedenen Plattformen gefunden werden kann.

Mit Nostr als Basis-Infrastruktur würden die Metadaten und die Binärdaten nicht an den Service gekoppelt sein, von dem aus sie bereitgestellt wurden. Binärdaten können auf sogenannten Blossom-Servern gehostet werden. Metadaten, Kommentare und weitere textbasierte Daten werden über die Relay-Infrastruktur verteilt. Da Daten und Service entkoppelt sind, können die OER Materialien von verschiedenen Anwendungen aus konsumiert werden.

Kuration

• Es gibt keine interoperablen Sammlungen
• Metadaten-Annotation ist zentralisiert
• User können keine eigenen Metadaten hinzufügen

Sammlungen sind per se interoperabel. Auf Protokollebene ist definiert, wie Listen funktionieren. Die Annotation mit Metadaten ist an keiner Stelle zentralisiert. Das Versprechen der RDF-Community "Anyone can say anything about any topic" wird hier verwirklicht. Ich muss mir ja nicht alles anhören. Vielleicht konsumiere ich nur Metadaten-Events bestimmter Redaktionen oder User. Vielleicht nur diejenigen mit einer Nähe zu meinem sozialen Graphen. Jedenfalls gibt es die Möglichkeit für alle User entsprechende Metadaten bereit zu stellen.

Crawling, Indexierung und Suche * An vielen Stellen wird Content doppelt erschlossen, aber immer für die eigene Plattform * Es gibt keinen geteilten Datenraum, in den Akteure Content "pushen" können * Es gibt keine plattformübergreifenden Suchmöglichkeiten

Keine Doppelerschließungen mehr. Wenn ein User im Netzwerk ein Metadatenevent veröffentlicht hat, ist es für alle konsumierbar. Der Datenraum ist per se geteilt. Plattformübergreifende Suche wird durch die Kombination aus Relays und NIPs ermöglicht. In den NIPs können spezielle Query-Formate für die jeweiligen NIPs definiert werden. Relays können anzeigen, welche NIPs sie untersützten. Eine plattformübergreifende Suche ist im Nostr eine relay-übergreifende Suche.

Plattformübergreifende Kollaboration

• Obwohl nun #OEP in aller Munde sind, gibt es keine technischen Ansätze, wie (plattformübergreifende) Kollaboration technisch abgebildet werden kann

Nostr ist der technische Ansatz.

KI-Services

• KI-Services funktionieren oft nur auf der Plattform für die sie entwickelt werden

Es gibt im Nostr das Konzept der Data Vending Machines (s. auch data-vending-machines.org). Statt also einfach nur eine API zu bauen (was auch schon sehr schön ist, wenn sie offen zugänglich ist), könnten diese Services auch als Akteure im Nostr Netzwerk fungieren und Jobs annehmen und ausführen. Die Art der Jobs kann in einer Spezifikation beschrieben werden, sodass die Funktionsweise für alle interessierten Teilnehmer im Netzwerk einfach nachzuvollziehen ist.

Die Services könnten sogar monetarisiert werden, sodass sich hier auch Möglichkeiten böten, Geschäftsmodelle zu entwickeln.

Fazit

Die Open Education Community ist großartig. Es sind einzigartige und unglaublich engagierte Menschen, die sich dem hehren Ziel "Zugängliche Bildung für Alle" -> "Offene Bildung" verschrieben haben. Wir verwenden Creative Commons Lizenzen -> Commons -> Gemeingüter. Es ist okay, dass viele Projekte von Sponsoren und Förderungen abhängig sind. Was wir machen, ist im Sinne eines Gemeingutes: Öffentliche Bildung für alle. Also zahlen wir als Gemeinschaft alle dafür.

Was nicht okay ist: Dass das, wofür wir alle gezahlt haben, nach kurzer Zeit nicht mehr auffindbar ist. Dass es eingeschlossen wird. In öffentlich finanzierten Datensilos. Es muss für alle auch langfristig verfügbar sein. Sonst ist es nicht zugänglich, nicht offen. Dann ist das O in OER nur ein Label und Marketing, um für eine ABM-Maßnahme 3 Jahre Geld zu bekommen. Denn nichts anderes ist Content-Entwicklung, wenn der Content nach drei Jahren weggeschmissen wird.

Und dasselbe gilt für OEP. Offene Lernpraktiken, sind auch nur eine Phrase, wenn wir die passende technische Infrastruktur nicht mitdenken, die wirkliche Offenheit und Kollaboration und damit die Umsetzung offener Lernpraktiken ermöglicht.

Und wenn wir uns jetzt nicht Gedanken darüber machen, die Infrastruktur für offenes Lernen anzupassen, dann werden wir vermutlich in einigen Jahren sehen können, was bei politischen Umorientierungen noch davon übrig bleiben wird. Wenn die Fördertöpfe komplett gestrichen werden, was bleibt dann übrig von dem investierten Geld?

Wir brauchen Lösungen, die engagierte Communities weiter betreiben können und denen kein Kopf abgeschlagen werden kann, ohne dass wir zwei neue daneben setzen könnten.

Wir müssen uns jetzt Gedanken darüber machen.

Wie offen will öffentliche Bildungsinfrastruktur sein?

Adam Back Invests SEK 21 Million to H100 Group Bitcoin Treasury Strategy

Today, H100 Group AB announced it has entered a SEK 21 million convertible loan from an investment agreement with Adam Back, with the option to expand his investment to SEK 277 million through a five-tranche convertible loan deal. The proceeds will be used to buy Bitcoin in alignment with H100 Group’s long-term Bitcoin treasury strategy.

H100 Group AB (Ticker: H100) secures a SEK 21M ($2.1M) commitment from @adam3us , with rights to invest an additional SEK 128M ($12.8M) in tranches—bringing the total contemplated raise to SEK 277M (~$27.7M). pic.twitter.com/c0HgMSRxut

— H100 (@H100Group) June 3, 2025

Under the agreement, Back may invest up to SEK 128 million across four additional tranches, with guaranteed participation of at least 50%. Each tranche is twice his committed amount, demonstrating his support for H100’s long-term growth.

The press release said, “Adam Back may request the Second Tranche within 90 days from signing of the Initial Tranche, the Third Tranche within 90 days from signing of the Second Tranche, the Fourth Tranche within 90 days from signing of the Third Tranche and the Fifth Tranche within ninety 90 days from signing of the Fourth Tranche. In the event Adam Back does not request a Future Tranche within the deadline, the right to request subsequent Future Tranches lapses.”

The convertible loans have no interest and have a five year maturity. At any time, Back may convert the loans into shares of the Company. Conversion prices are fixed per tranche: SEK 1.75 per share for the initial tranche, rising to SEK 5.00 by the fifth tranche. H100 retains the right to force conversion if the stock price exceeds the conversion rate by 33% over a 20 day period. Full conversion of the initial tranche would result in 12 million new shares and a 9.3% dilution.

“Upon request of a tranche Adam Back is obliged to invest in the relevant Tranche with SEK 15,750,000 in the second tranche, SEK 23,625,000 in the third tranche, SEK 35,437,500 in the fourth tranche, and SEK 53,156,250 in the fifth tranche,” stated the press release. “The contemplated size for each tranche is twice the entitled amount of Adam Back.”

Blockstream has “been around since 2014 and we work with our investors to put Bitcoin in a balance sheet back then and since then,” said Adam Back at the 2025 Bitcoin Conference. “I think the way to look at the treasury companies is that Bitcoin is effectively the hurdle rate; it’s very hard to outperform bitcoin. Most people that have invested in things since bitcoin has been around have thought, ‘oh, I should have put that in bitcoin and not in the other thing.”

The Algorithmic Pursuit of Connection: A Five-Book Journey into the Self

As a researcher, hitting my thirties and the winding down of a significant project prompted a crucial re-evaluation of life's latter half. While I'd successfully applied probabilistic control theory to one-on-one interactions, the complexities of group dynamics remained a persistent challenge. My recent dive into five diverse books on human relationships inadvertently became a profound journey of self-discovery, fundamentally reshaping my perspective on social connections.

---

Neil Strauss: A Mirror Reflecting the Self's Evolution

Neil Strauss's The Truth resonated deepest among my recent reads. The author's battle with sex addiction uncomfortably mirrored my own past struggles: the fragile self-esteem stemming from rejection, the hubris born of early successes, and the tendency to view women as mere objects of manipulation. It felt eerily prescient, a glimpse into a potential future.

Yet, I found myself arriving at Strauss's ultimate conclusion – the paramount importance of self-preparation and community – far sooner than he did. This acceleration wasn't accidental; it was the result of intense focus on individual experiences, meticulously replayed and analyzed in my mind. The book, therefore, served less as a revelation and more as a powerful validation of my own journey of introspection and root-cause analysis.

---

Quantifying Connection: The Promise and Limits of Mathematical Models

Hannah Fry's The Mathematics of Love offered a kindred spirit in its attempt to quantify human relationships. While I appreciate the mathematical lens, Fry's models primarily concern dyadic relationships (N=2), relying on relatively simple systems of two-variable ordinary differential equations. For me, these are akin to linear models, sufficient only up to a certain point. Beyond N=4, the dependencies become exponentially complex.

My own pursuit extends to understanding and optimizing group dynamics within complex systems. This involves multi-variable problems (N $\ge$ 3) and the application of network theory, a far more sophisticated approach. Human collectives, after all, are systems of nodes and edges, where information propagates in predictable ways. My focus is on deriving optimal behavioral controls within these intricate frameworks.

Conversely, Men Are from Mars, Women Are from Venus initially struck me as bordering on conspiracy theory. However, its latter half proved unexpectedly useful. Its clear enumeration of male and female desires, and its articulation of common points of conflict, presented a practical template for communication styles. In a systemic view, this serves as a rudimentary, yet functional, interface design for complex social interactions.

---

A Dispassionate Critique of Relationship Dogma

My drive for efficiency and systematic understanding led to a rather blunt assessment of certain relationship classics. The New Science of Adult Attachment felt disorganized and frustratingly anecdotal. Lacking a coherent theoretical framework, it burdened the reader with deciphering meaning from a jumble of examples. Its inefficiency was, frankly, its most irksome flaw.

Similarly, Dale Carnegie's How to Win Friends and Influence People struck me as closer to pseudoscience than social science. Its plethora of specific anecdotes obscured any underlying principle. Given my deep engagement with social engineering – a discipline that systematically and practically analyzes human interaction – Carnegie's work appeared largely irrelevant and inefficient. From my perspective, which views humans as objective systems to be analyzed with mathematical rigor, such unstructured approaches hold little value.

---

The Unveiling of a Core Principle: Humans as Systems

This intensive reading period solidified my most crucial insight: humans, at their core, are systems. This understanding allows for a dispassionate, methodical approach to human collectives, mitigating unnecessary emotional friction.

This revelation has sharply refined my future learning trajectory. I'm now prioritizing foundational theories like graph theory and network theory over anecdotal accounts of human behavior. By mastering these theoretical underpinnings, I aim to precisely model complex human interactions as systems of nodes and edges, enabling the derivation of optimal behavioral controls within communities.

My choice of the term "target for capture" for individuals stems from a personal aversion to perceived equality in certain human interactions, a mechanism to avoid cognitive dissonance. This rational approach, I believe, is key to cultivating secure attachment styles – relationships demonstrably sustainable in the long term. My philosophy is to strategically approach the initial engagement, then transition to a stable, enduring connection. It's a calculated, dispassionate method for achieving desired relational outcomes.

Ultimately, this period of reading wasn't just about acquiring knowledge; it was a profound journey of self-discovery, clarifying my personal frameworks for navigating life's complexities and forging meaningful, yet strategically managed, connections.

Nos últimos anos, o Bitcoin tem sido frequentemente comparado ao ouro, ganhando o nome de "ouro digital". Essa comparação ocorre porque ambas as formas de valor têm características em comum, como escassez, durabilidade e aceitação mundial. Contudo, o Bitcoin também representa uma novidade tecnológica que muda a ideia de dinheiro e investimento, se destacando como uma alternativa moderna e eficaz ao ouro físico.

Uma das razões pelas quais o Bitcoin é comparado ao ouro é a sua escassez programada. Enquanto o ouro é um recurso natural limitado, cuja oferta depende da mineração, o Bitcoin tem um teto máximo de 21 milhões de unidades, definido em seu código. Esse teto faz com que o Bitcoin seja protegido contra a inflação, ao contrário das moedas tradicionais, que podem ser criadas sem limites pelos bancos centrais.

Essa característica traz um valor duradouro, parecido com o ouro, já que a oferta limitada ajuda a manter o poder de compra ao longo do tempo. Com o aumento da procura por Bitcoin, sua quantidade reduzida reforça seu papel como reserva de valor.

Outro aspecto que aproxima o Bitcoin do ouro é a durabilidade. Enquanto o ouro resiste à corrosão e pode ser guardado por séculos, o Bitcoin é um ativo digital protegido por criptografia avançada e armazenado na blockchain — um livro-razão imutável e descentralizado.

Além disso, o Bitcoin é mais fácil de transportar do que o ouro. Mover ouro físico envolve custos e segurança, tornando o transporte complicado, principalmente em transações internacionais. Por outro lado, o Bitcoin pode ser enviado digitalmente para qualquer parte do mundo em minutos, com taxas baixas e sem intermediários. Essa vantagem tecnológica torna o Bitcoin mais eficaz para um mundo globalizado e digital.

A segurança é outra característica que o Bitcoin e o ouro têm em comum. O ouro é difícil de falsificar, fazendo dele uma reserva de valor confiável. Da mesma forma, o Bitcoin usa protocolos de criptografia que asseguram transações seguras e protegidas contra fraudes.

Além disso, todas as transações feitas com Bitcoin são registradas na blockchain, fornecendo um nível de transparência que o ouro físico não oferece. Qualquer pessoa pode revisar as transações na rede, aumentando a confiança e a rastreabilidade.

EconômicaHistoricamente, o ouro tem sido utilizado como proteção contra a inflação e crises econômicas. Durante momentos de instabilidade, os investidores buscam o ouro como uma maneira de preservar seu patrimônio. O Bitcoin, por sua vez, está surgindo como uma alternativa digital com o mesmo propósito.

Em países com alta inflação ou instabilidade política, o Bitcoin tem sido usado como uma proteção contra a desvalorização das moedas locais. Sua natureza descentralizada impede que governos confisquem ou controlem diretamente o ativo, garantindo maior liberdade financeira para os usuários.

Apesar de suas semelhanças com o ouro, o Bitcoin ainda enfrenta desafios. Sua volatilidade é muito maior, o que pode causar incertezas a curto prazo. No entanto, muitos especialistas afirmam que essa volatilidade é uma característica comum em ativos novos e tende a diminuir com o tempo, à medida que a aceitação cresce e o mercado se desenvolve.

Outro desafio é a regulamentação. Enquanto o ouro já é reconhecido globalmente como um ativo financeiro, o Bitcoin ainda enfrenta resistência de governos e instituições financeiras, que procuram formas de controlá-lo e regulá-lo.

Resumindo, o Bitcoin, muitas vezes chamado de "ouro digital", oferece uma nova forma de valor que combina as melhores características do ouro com a eficiência e a inovação da tecnologia digital. Sua escassez planejada, segurança criptográfica, portabilidade e resistência à censura fazem dele uma alternativa viável para preservar riqueza e realizar transações no mundo moderno.

Mesmo com muita volatilidade, o Bitcoin está se firmando como uma reserva de valor e como um ativo de proteção contra crises econômicas. Assim, ele representa não apenas uma evolução do sistema financeiro, mas também um símbolo da mudança para uma economia digital descentralizada e global.

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

Bitcoin Miners Pivot to Power AI Boom, Offering a Lifeline to America’s Data-Center Crunch

A fresh Morgan Stanley analysis warns that U.S. data-center demand will balloon to ≈65 GW between 2025 and 2028—about 45 GW more than the grid can currently supply. One solution the bank singles out: repurposing the oversized, transformer-fed campuses originally built for Bitcoin mining. (investopedia.com)

Several public miners are already moving. Riot Platforms has begun buying extra land near its Corsicana, TX complex and hired a veteran data-center executive to head a “high-performance compute” division aimed squarely at AI customers. (riotplatforms.com, coindesk.com) Bitfarms, meanwhile, is marketing North-American sites to hyperscalers after hiring consultants to evaluate GPU-ready retrofits. (reuters.com)

Industry analysts say the pivot is existential. April 2024’s fourth halving chopped block rewards to 3.125 BTC, shrinking miner revenue just as network difficulty hit record highs. By leasing idle megawatts—or fully converting halls—operators lock in dollar-denominated cash-flows while retaining the option to resume mining if margins rebound.

“Miners spent the last cycle amassing land, switchgear and transformers. AI is about to pay them for it.” —Greg Miller, Citizens JMP (research note quoted in multiple sector briefings)

Why it matters

• Grid relief: Every gigawatt shifted from speculative hashing to AI compute eases ERCOT’s peak-load stress and shortens transmission-upgrade timelines. (datacenterdynamics.com)
• Cap-ex savings for cloud firms: Retrofitting a mining hall is months faster—and currently 30-40 % cheaper—than green-field construction, analysts estimate. (govtech.com)
• Dual-revenue model: Miners keep upside to future BTC price spikes while monetizing power capacity today.

The roadblocks

• Cooling retrofits: Air-cooled ASIC barns must be re-engineered for liquid-cooled GPU clusters, at up to \$3 M per MW in conversion costs. (driehaus.com)
• Policy risk in Texas: Lawmakers are weighing caps on industrial load-flex credits after recent grid-stress events, which could dent miners’ ancillary revenue. (dallasnews.com)

Bottom line: Once-beleaguered Bitcoin mines may become critical real estate for the surging AI sector—turning yesterday’s crypto boomtowns into tomorrow’s compute hubs while giving miners a much-needed new income stream.

Chorus: تجربة في البرمجة الانسداحية

كيفية بناء تطبيق Nostr بسرعة البرق باستخدام الذكاء الاصطناعي.

في 26 مايو، تم إطلاق تطبيق Chorus في منتدى أوسلو للحرية. صُمم هذا التطبيق للناشطين والمعارضين ومنظمي المجتمع، ويتميز بمجموعات تشبه تلك الموجودة في فيسبوك مع محفظة eCash مدمجة لجمع التبرعات.

Chorus مبني على Nostr، وهو بروتوكول لامركزي ومفتوح مصمم ليكون مقاومًا للرقابة. يمكن لأي شخص في العالم إنشاء حساب Nostr والنشر إلى خوادم Nostr، أو حتى بناء تطبيق Nostr خاص به — ولا يمكن لأحد إيقافه. هذا ما يجعل Nostr المكان المثالي للمقاتلين من أجل الحرية، الذين غالبًا ما يواجهون الرقابة من الحكومات الاستبدادية أو الشركات التي تتحكم في المنصات الاجتماعية الرئيسية.

يمكن للمستخدمين إنشاء حساب Chorus (أو تسجيل الدخول باستخدام حساب Nostr موجود) في ثوانٍ والبدء فورًا في استلام eCash، وإنشاء مجموعات، ومشاركة المحتوى. يتضمن التطبيق ميزات قوية لإدارة المجتمع، بحيث يمكن للمجموعات اختيار أنواع المحتوى التي تسمح بها وفقًا لشروطها الخاصة. يمكن للمستخدمين إرسال eCash على الفور إلى المجموعات التي يرغبون في دعمها، مما يوفر أداة لجمع التبرعات عبر الحدود لا يمكن لأي حكومة إيقافها.

قبل عام فقط، ربما استغرق بناء النسخة التي تم إطلاقها الأسبوع الماضي من Chorus أسابيع. ولكن بفضل أدوات الذكاء الاصطناعي الحالية، قمنا بذلك في خمسة أيام فقط.

⸻

كيفية القيام بذلك: بناء تطبيق في أيام باستخدام وكلاء الذكاء الاصطناعي

الخطوة 1: تجميع الفريق

تم بناء Chorus بواسطة And Other Stuff، وهي مجموعة جديدة مكرسة لتعزيز Nostr في خمسة مجالات رئيسية: تجربة المستخدم والتسجيل، المجتمعات، الاتصالات الخاصة، التجارة، والذكاء الاصطناعي. شمل فريق هذا المشروع: • Calle، منشئ Cashu (eCash) • JeffG، منشئ White Noise (الاتصالات الخاصة) • Rabble و Liz Swiegart من Nos (تجربة المستخدم والتسجيل) • Alex Gleason و MK Fain، منشئو Soapbox (المجتمعات) • و Jack Dorsey (مستشار)

الخطوة 2: البدء بقالب قوي

عند البرمجة بالانسداح، السياق هو الملك. إذا بدأت بمجلد فارغ وطلبت من وكيل ذكاء اصطناعي “بناء تطبيق مجموعات Nostr”، فلا يزال أمامك الكثير من العمل للحصول على شيء وظيفي حتى بشكل بسيط. من المحتمل أن تكون تنفيذات Nostr محاكاة، لا تتصل بخوادم حقيقية، أو تم تنفيذها بشكل غير صحيح. قد تكون أنواع الأحداث خاطئة، وقد لا يتم تحميل واجهة المستخدم، وحظًا سعيدًا في محاولة معرفة الخطوة التالية لإصلاح الفوضى.

هذا لأن الذكاء الاصطناعي يفتقر إلى بعض السياقات الرئيسية للبدء: • وثائق صديقة للذكاء الاصطناعي حول بروتوكول Nostr • أمثلة عالية الجودة على تنفيذ Nostr • أساسيات حول تكديس التكنولوجيا المفضل • سياق حول كيفية بناء المشروع وتشغيله وتصحيحه

الحل هو توفير المزيد من السياق، وسيكون العديد من مبرمجي الانسداح المخضرمين على دراية بالصراع في محاولة جعل الوكيل يقرأ روابط مختلفة للوثائق ويتبع 500 كلمة من السياق المصاغ بعناية في مطالبتهم الافتتاحية. ومع ذلك، غالبًا ما يربك هذا الوكلاء الذين يعملون بشكل أفضل مع مطالبات بسيطة. الحل لهذه المشكلة هو Stacks.

Stacks: بدء البرمجة الانسداحية بسرعة

Stacks تحل مشكلة نقص السياق الأولي من خلال إنشاء قوالب جاهزة مصممة خصيصًا لاستخدام وكلاء الذكاء الاصطناعي. يمكن استخدام “stack” لبناء أي نوع من المشاريع بأي لغة برمجة مع أي هدف نهائي في الاعتبار. بالنسبة لـ Chorus، استخدمنا MKStack، وهو قالب مصمم خصيصًا لبناء تطبيقات Nostr.

يتميز MKStack بعدة حلول للمشاكل الشائعة في الذكاء الاصطناعي: • Nostrbook MCP للاستعلام عن وثائق Nostr • مكونات بداية لميزات Nostr الشائعة مثل تسجيل الدخول • دعم Blossom لتحميل الوسائط • ملفات سياقية لتوجيه الوكيل خلال العقبات الشائعة وسير عمل التصحيح • نشر موقعك على الفور باستخدام Surge

النتيجة هي موقع جميل يعمل مباشرة مع Nostr في مطالبة واحدة:

“بناء تطبيق مجموعات على غرار فيسبوك على Nostr باستخدام NIP 72.”

كان هذا هو نتيجة تلك المطالبة الواحدة: http://groups72.surge.sh

الخطوة 3: إضافة الميزات باستخدام وكلاء الذكاء الاصطناعي

Stacks بدأت تطوير Chorus بسرعة. بعد ذلك، استخدمنا وكلاء الذكاء الاصطناعي لإضافة ميزات إضافية مثل: • محفظة eCash مدمجة • ميزات إدارة المجتمع • دعم الوسائط المتعددة

كل ذلك تم باستخدام مطالبات بسيطة وتوجيهات للذكاء الاصطناعي، مما سمح لنا ببناء تطبيق كامل الوظائف في أيام قليلة فقط.

O surgimento do Bitcoin trouxe uma nova visão para o conceito de dinheiro, desafiando o sistema financeiro convencional baseado em moedas fiduciárias. Enquanto as moedas fiduciárias, como o real, o dólar e o euro, são amplamente usadas e reconhecidas como métodos de troca, o Bitcoin representa uma inovação digital que propõe descentralização e autonomia financeira. Embora ambos desempenhem funções básicas como meio de troca e reserva de valor, suas diferenças principais estão na maneira como são emitidos, geridos e transacionados.

Uma das principais distinções entre o Bitcoin e as moedas fiduciárias é a maneira como são emitidos e administrados. As moedas fiduciárias são emitidas por bancos centrais, que têm o poder de regular sua quantidade em circulação. Esse modelo permite a aplicação de políticas monetárias, como o aumento da oferta de dinheiro para estimular a economia ou a diminuição para controlar a inflação. No entanto, essa capacidade também pode resultar na desvalorização da moeda, se for emitida em excesso.

O Bitcoin, por outro lado, tem um sistema de emissão totalmente descentralizado. Ele é criado por meio de um processo chamado mineração, no qual computadores resolvem problemas matemáticos complexos para validar transações na rede. Além disso, a oferta total de bitcoins é limitada a 21 milhões de unidades, tornando-o um ativo deflacionário, ou seja, sua escassez pode aumentar seu valor ao longo do tempo. Essa limitação contrasta fortemente com a natureza ilimitada da impressão de moedas fiduciárias.

Moedas fiduciárias são centralizadas, o que significa que sua emissão e controle são decididos por autoridades governamentais. Isso também implica que transações feitas com essas moedas passam por intermediários, como bancos, que podem aplicar taxas e limites, além de estarem sujeitos a regulamentações e auditorias.

O Bitcoin, por sua vez, é descentralizado. Ele opera em uma rede peer-to-peer, onde as transações são verificadas por participantes chamados mineradores e registradas em um livro público conhecido como blockchain. Essa descentralização elimina a necessidade de intermediários, tornando o Bitcoin mais resistente à censura e ao controle governamental. Isso também proporciona maior transparência, já que qualquer pessoa pode verificar as transações na rede.

Outra diferença importante está na maneira como as transações são feitas. Com moedas fiduciárias, as transações geralmente dependem de bancos ou sistemas de pagamento, que podem impor restrições de horários e taxas altas, especialmente para transferências internacionais.

O Bitcoin, por outro lado, permite transferências diretas entre pessoas, em qualquer lugar do mundo e a qualquer momento, sem a necessidade de intermediários. Isso torna o sistema mais acessível, especialmente para aqueles que não possuem contas bancárias ou vivem em países com sistemas financeiros restritivos. Além disso, as taxas de transação do Bitcoin podem ser menores do que as taxas cobradas por bancos tradicionais.

As moedas fiduciárias proporcionam segurança baseada em leis governamentais e no sistema bancário, mas os usuários precisam confiar nesses intermediários. O Bitcoin, em contrapartida, oferece um alto nível de segurança através de criptografia avançada. As carteiras digitais, que guardam bitcoins, são protegidas por chaves privadas, assegurando que somente o dono possa acessá-las.

No entanto, a privacidade funciona de maneira diferente. Transações em moedas fiduciárias normalmente estão ligadas à identidade do usuário, enquanto o Bitcoin oferece um certo nível de anonimato, já que os endereços das carteiras não requerem identificação pessoal. Ainda assim, todas as transações são públicas e registradas no blockchain, o que pode ser um ponto de monitoramento para autoridades.

O valor das moedas fiduciárias é sustentado pela confiança no governo que as emite e na economia do país. Por outro lado, o Bitcoin não é apoiado por nenhum governo ou ativo físico. Seu valor é definido pela oferta e demanda no mercado, fazendo com que seja altamente volátil. Embora essa volatilidade apresente um risco, também atrai pessoas que veem o Bitcoin como uma possibilidade de valorização a longo prazo.

Resumindo, o Bitcoin e as moedas fiduciárias diferem significativamente em sua estrutura, controle e funcionalidade. Enquanto as moedas fiduciárias são controladas por governos e dependem de intermediários, o Bitcoin oferece descentralização, transparência e liberdade financeira. Apesar de sua volatilidade e alguns desafios relacionados à regulamentação, o Bitcoin representa uma alternativa nova ao sistema financeiro tradicional.

So Much… and Still, Not Feeling It

So much abundance. It’s everywhere—overflowing around me. My six-year-old car would be a magical carriage to kings and queens of old. And yet, I get in, turn the key, and don’t often Feel The Magic.

Do I let myself feel how abundant life is? Eh. That does not come by default for me.

Adapting Is Normal. Savoring Is Not.

I adapt. I’m good at it. Weather shifts 40 degrees? No problem. A new location? I’ll adjust. And that’s useful—it keeps me moving. But it also numbs me. If I only adapt, life flattens out. That’s not thriving. That’s functioning.

Thriving, I’ve come to feel, asks for something more.

Our ancestors had rituals. They didn’t just adapt… they paused to feel the blessings, to name them. That created richness—not just survival. And today? I can have food delivered to my door. Are you a king? No—just have Amazon Prime.

Still, I want more than convenience. I want connection. To the food I eat. The flowers that bloom. The people I love. I want to feel that connection in my bones.

My Engineer Brain Doesn’t Celebrate

And yet, my mind often slips into improvement mode. I see what could be better. Smoother. More efficient. Useful? Sure. Celebratory? Not so much.

So I’ve started something: at the end of each day, when I look at my to-do list, I take a breath. I ask: what were the blessings today? Not just the big ones—because we adapt to those too. A new car? A new house? We get used to it. Quickly. But the micro-blessings… those are different.

My daughter’s laugh at a silly face I made yesterday. That memory settles deeper when I notice it and write it down. That’s a micro-blessing. I want to feel more of those.

And after about 75 days of doing this nightly pause, I’m noticing something surprising: my dreams are changing. They’re weaving in those sweet, ordinary moments. They say, “Yes. Adapt. And also savor.”

The Confusion Between Privilege and Blessing

But here’s something raw. Something I’ve hesitated to share.

I’m a white man. An older one. And I’ve been in spaces where “white male privilege” is spoken as a curse. I absorbed that. My body did. And it twisted something deep inside me. Because in my system, “privileged” and “blessing” are linked.

So I started feeling that feeling blessed was wrong. Like I should shrink from it. That it was unfair, maybe even immoral.

I’ve had to tap through that.

Is it okay to feel blessed? Not above anyone—but blessed to have food. Skill. Mobility. A car that works. Is it okay?

Yes.

I Don’t Want to Shrink or Perform

Scarcity and guilt are real energies, but I don’t want them steering my experience of life. I want to choose presence. Connection. I want to know in my body: I am blessed. And I can feel that without disconnecting from those who are struggling.

I don’t want to perform gratitude out of duty. But I also don’t want to avoid it out of shame.

Practicing Our Birthright

Abundance is our birthright. Many of us are born with protections our ancestors could barely dream of—shelter, clean water, safety from predators. And if we want to truly be thriving, not just surviving, it feels essential to practice remembering that.

Because adaptation will keep us alive.

But only conscious attention to blessings—only savoring—will let us thrive.

Useful Concepts for Thriving in This Story

• Abundance\ Abundance is the felt experience of more-than-enoughness, when we pause to really receive what surrounds and sustains us.

• Adapting\ Adapting keeps us functional, but thriving asks us to adapt and engage with what truly nourishes us.

• Awareness\ Awareness brings the blessings into view—even the ones so small they almost disappear without it.

• Allowing\ Allowing lets us stay open to blessings, even when shame or guilt try to close the door.

• Thriving\ Thriving means more than surviving—it’s about feeling, savoring, and aligning with life’s richness.

In dem Video geht es um Dietrich Bonhoeffer, wie er sich zu Dummheit und vorsätzlicher bzw. rationaler Ignoranz geäußert hat. Schon seit einiger Zeit geht bei vielen Seltsames vor: Sie werden mit einem Thema persönlich konfrontiert und postum gibt es genau zu diesem Thema ein Video oder einen Artikel. Das kommt manchmal so vor, wie ein Frage- und Antwort-Spiel innerhalb der Schwarm-Intelligenz. Irgendwie spooky.

Die erschreckende Theorie der Dummheit, die Sie nie hören sollten - Dietrich Bonhoeffer: https://www.youtube.com/watch?v=PH-Vs5ILEko

Dem Entdecken, oder besser, dem Auf-einen-Zukommen, ist dieser E-Mail-Schriftverkehr in zeitlichem Zusammenhang vorausgegangen:

Nachfrage zu einem Aufruf durch einen Mitarbeiter zur Blutspende in einem Unternehmen mit über 100 Mitarbeitern über den E-Mail-Verteiler:

Lieber XXXXXXX,

danke zunächst für Dein Engagement.

In meiner näheren Familie gibt es jemanden, der regelmäßig Blut spendet, daher bin ich ein wenig für das Thema sensibilisiert.

Seit Du die E-Mail verschickt hast, gehe ich damit „schwanger“, ob ich ein vielleicht „heißes Eisen“ anfassen soll.

In den angehängten Informationen (des Roten Kreuzes) steht, dass das gespendete Blut auf bestimmte „Verunreinigungen“ durch Vorerkrankungen untersucht wird. Was nicht aufgeführt ist, ist eine Untersuchung, von der ich noch nicht einmal weiß, ob sie überhaupt schon durchgeführt wurde, und wenn ja, zu welchem Ergebnis sie gekommen ist, ob das gespendete Blut auch mit Substanzen der Corona-Gen-Behandlung verunreinigt sein kann. Leider zeigen ja die aktuellen Erkenntnisse, dass das Spike-Protein noch nach Jahren aktiv sein kann. Auch in gespendetem Blut? Die konkrete Frage wäre, ob das Rote Kreuz definitiv ausschließen kann, dass das nicht der Fall ist, damit ein möglicher Schaden nicht die Gefahr läuft, größer zu sein, als der Nutzen.

Soweit ich weiß, hat das Rote Kreuz bis heute keine separaten Blutbanken von „geimpftem“ und „ungeimpftem“ Blut angelegt. Wenn zu 100% ausgeschlossen werden kann, dass keine schädlichen Substanzen der Gen-Behandlung in die Blutkonserve gelangen, wäre das ja natürlich nicht nötig. Ist das so? Wenn ja, wo ist der Nachweis dazu zu finden, wie ist der aktuelle Erkenntnisstand, von wem wurden Studien dazu erarbeitet, wer hat das finanziert?

Mindestens 20% der Bevölkerung, das sind rund 16 Millionen Menschen, haben auf die Gen-Behandlung verzichtet und wollen im Ernstfall kein kontaminiertes Blut empfangen. Wie kann das Rote Kreuz belegbar und glaubhaft nachweisen, dass möglicherweise verunreinigtes Blut nicht doch in die Blutkonserven gelangt, weil sonst die Gefahr besteht, dass im Ernstfall Impfverzichter einen Schaden davontragen könnten?

Ich finde das eine wichtige Frage dem Roten Kreuz gegenüber und vielleicht wäre es auch gut, die möglichen Spender im Vorfeld für dieses heikle Thema zu sensibilisieren. Ich finde es auffällig, dass das Rote Kreuz sich hierzu weder in die eine, noch andere Richtung in den Informationen äußert, obwohl sie uns alle betrifft.

Ich schreibe diese Email aus kollegialen Gründen, aber auch zur Sensibilisierung gegenüber der Verantwortung aller Menschen gegenüber ihren Mitmenschen, die (hoffentlich nie) in die Situation kommen, einmal auf eine Blutspende angewiesen zu sein.

Wenn sich etwas Neues auf meine Nachfrage an Dich ergibt, wäre es klasse, ich würde davon erfahren.

Vielen Dank und viele Grüße

YYYYYYY

(Die Intension war, sich so vorsichtig wie möglich, quasi auf „Samtpfötchen“, an den Kern heranzupirschen. Dass es bereits Erkenntnisse dazu gibt, dass das Blut kontaminiert sein kann, wurde bewusst weggelassen, um keine Angriffsfläche zu bieten, ein „Verschwörungstheoretiker“ zu sein. Wenn die andere Seite auf einen Austausch eingestiegen wäre, wäre eine Quelle zu dieser Aussage vorhanden gewesen.)

Die Antwort:

Hallo YYYYYYY,

danke für die ausführliche Nachricht und dass du dir Gedanken zu dem Thema machst. Ich finde, man sollte Blutspenden als eine persönliche und private Sache betrachten.

Jeder und jede sollte für sich selbst abwägen, ob und unter welchen Bedingungen er oder sie das tun möchte.

Die Fragen, die du gestellt hast, sind echt speziell. Da geht's um medizinische und wissenschaftliche Themen, da kann ich als Privatperson nicht mitreden. Ich denke, dass sich Interessierte bei solchen Themen am besten direkt an medizinische Fachstellen oder das Rote Kreuz vor Ort wenden sollten, um fundierte und belastbare Informationen zu erhalten.

Mir persönlich ist es wichtig, Menschen auf die Möglichkeit der Blutspende aufmerksam zu machen.

Jeder kann das für sich selbst entscheiden und es ist auch okay, wenn man dabei Überzeugungen hat.

Beste Grüße

XXXXXXX

(„Blutspende…eine persönliche und private Sache“, nach dem Corona-Ereignis auch noch?, „…ich als Privatperson“ empfehle anderen etwas, bei dem sie möglicherweise anderen einen Schaden zufügen. Ist das schon grob fahrlässig, nach den Denkanstößen, die gegeben wurden?, „Wenn man dabei Überzeugungen hat.“, interessante Formulierung.)

Darauf die Reaktion:

Hallo XXXXXXX,

danke auch für Deine Antwort.

Wenn so eine im Grundsatz sicher gute Aktion beworben wird, liegt es nach meinem Empfinden auch in der Verantwortung, auf mögliche Folgen hinzuweisen, wenn es das Rote Kreuz schon nicht tut. Vorausgesetzt, man misst ihnen Bedeutung zu. Wenn meine E-Mail keine Veranlassung zu einer Beunruhigung und eigener Recherche angeregt hat, dann kann ich leider mehr nicht tun.

Dass das Rote Kreuz keine Hinweise gibt, liegt wohl daran, dass es Teil des Systems ist. Wer die Augen aufmacht, kann mit wenig Aufwand leider mehr als genug Tatsachenwahrheiten finden, die mit Schäden im Zusammenhang der Gen-Behandlung verursacht wurden und immer noch verursacht werden. Es ist nicht meine Aufgabe, einen Wissensrückstand von 5 Jahren auf den aktuellen Stand zu bringen. Allein die veröffentlichten RKI-Protokolle sollten schon genug Anlass zur Skepsis bieten. Der ÖRR berichtet leider nicht darüber, weil er auch Teil des Systems ist.

Ich will es damit genug sein lassen und hoffe, dass es unter den Kolleginnen und Kollegen noch weitere kritische Geister gibt.

Es geht nicht gegen Dich persönlich, aber ich hoffe, das Angebot wird nicht zahlreich genutzt.

Viele Grüße

YYYYYYY

(Einen halben Gang hochgeschaltet, ein Versuch, XXXXXXX aus der Reserve zu locken.)

Und ein Nachtrag von YYYYYYY:

Lieber XXXXXXX,

wir sind schon einmal unter Missbrauch des Begriffes „Solidarität“ hinter die Fichte geführt worden. Das darf nicht noch einmal passieren!

Nochmals viele Grüße

YYYYYYY

(Keine Reaktion mehr von XXXXXXX)

Und, wie gesagt, daraufhin kam das Video mit Bonhoeffer entgegen. Besser kann man vorsätzliche, rationale Ignoranz in Bezug auf den Schriftwechsel nicht beschreiben.

Hier wird eine jeden angehende allgemeinmedizinische Frage zu einer Frage der persönlichen Überzeugung gemacht. Das kommt doch sehr bekannt vor, oder?

Sehr wahrscheinlich lässt es sich vermuten, dass es sich bei XXXXXXX wohl um einen Corona-Jünger handelt, der die Tatsachen scheut, wie der Teufel das Weihwasser. Bloß nicht nachdenken, bloß nicht in Frage stellen, bloß nicht hellhörig oder gar neugierig werden, bloß nicht auf die Äußerungen eingehen, bloß nicht konkret werden, bloß keine eindeutig formulierte Stellung zu den Aussagen beziehen. „Angriffsfläche“ wäre vorhanden gewesen.

Das vorsichtige Anpirschen war alles andere, als mit-der-Brechstange-herangehen. Und doch setzt sofort automatisch der Teflon-Effekt ein. Selbstschutz.

Die Frage ist, wie soll da die Spaltung überwunden werden, wenn „die andere Seite“ so überhaupt nicht bereit ist, sich mit dem Vorgebrachten auseinanderzusetzen. Noch nicht einmal, wenn man nur die Spitze der Spitze des Eisbergs leise anhaucht.

Diesem Beispiel könnten viele unzählige weitere Beispiele hinzugefügt werden. Jeder hat so etwas schon einmal auf die eine oder andere Weise erlebt.

Das Gefühl lässt sich nicht unterdrücken, dass sich die Menschheit in zwei Lager aufgeteilt hat, und es gibt derzeit keinen Weg, wie man wieder aufeinander zukommen könnte.

Wie zwei Welten aufeinanderprallen, kann man derzeit auch in der Enquete-Kommission im sächsischen Landtag erleben: https://www.youtube.com/watch?v=D6ACmwBUBFM

Aus der Sicht von YYYYYYY ist das kein Grund zur Verzweiflung, jedoch drängt sich der Wunsch auf, dass man mit solchen Menschen wie XXXXXXX nichts mehr anfangen will. Man möchte mit ihnen, so schade es auch ist, am liebsten gar nichts mehr zu tun haben, und wenn doch aus irgendwelchen Gründen, nur noch das Allernotwendigste, so kurz und knapp, wie möglich. Empathie aufzubringen erscheint einem als vergeudete Energie, besser ist es, sich auf die Menschen zu konzentrieren, die wegen fehlender Genbehandlung keine Wesensveränderungen, die mittlerweile leider auch schon bestätigt sind, erlitten haben.

Wie Bonhoeffer richtig sagt, es geht hier nicht um Intelligenz, es geht viel tiefer. Es geht um das Menschsein an sich, und man hat den Eindruck, dass vor allem dies unter dem Einfluss der Spritze sehr stark gelitten hat. Da scheint so eine Abgestumpftheit durch, die einem einen kalten Schauer über den Rücken fahren lässt. Und das ist vielleicht noch gefährlicher, als diejenigen, die wirklich dumm sind. Das ist keine Arroganz oder Überheblichkeit, sondern unschuldig, wahllos von der Natur vergebene Dummheit, die jeden hätte ereilen können, hat es immer schon zu einem großen Teil gegeben. Hier hat man wenigstens noch die Möglichkeit, sich einfühlen zu können und Verständnis aufzubringen. Bei Menschen aber, von denen man weiß, dass sie die kognitiven Fähigkeiten zur Reflektion hätten, sie jedoch aus welchen Gründen auch immer nicht nutzen, oder sie als Verdrängungsmechanismus gerade nutzen, weil sie es können, geht auch eine gewisse Gefahr aus, weil man nie wissen kann, was sie sich sonst noch so ausdenken könnten, wenn sie in die geistige Enge getrieben werden, um ja nicht von Menschen, die den Mut haben, die Wahrheit auszusprechen, in ihrem mühsam aufgebauten Weltbild erschüttert zu werden. „Was nicht sein darf, das nicht sein kann!“, obwohl doch eigentlich die Wahrheit dem Menschen zumutbar ist.

So hat man das Gefühl, man atmet Honig ein und bewegt sich mühsam durch einen zähen Brei vorwärts, der einem bis zu den Oberschenkeln reicht. Jeder Schritt eine Anstrengung.

Und bevor man noch tiefer in dieses Verlustgefühl von Lebensqualität eintaucht (das hat nichts mit Depressionen zu tun, man bekommt einfach nur schlechte Laune), sich immer wieder bewusst machen, dass es da draußen noch eine Menge bei Verstand gebliebener Menschen gibt, die unermüdlich daran arbeiten, dass die Wahrheit weiter so sehr erkraftet, dass sie sich ihren Weg in den sogenannten Mainstream bahnt und die Menschen endlich aufwachen. So schmerzlich das für viele sein mag, es muss sein!

Selbst für einen wenig religiösen Menschen, im Sinne von regelmäßigen Kirchgängen und keinem Kontakt zur Institution Kirche, bekommt der Satz eine ganz besondere Bedeutung:

„Ich schicke euch den Geist der Wahrheit, und der wird euch frei machen!“

Think crypto analytics is just charts and graphs? Wrong. It's a crystal ball for savvy investors.

Analytics in crypto decodes blockchain data revealing hidden trends. It transforms complex data into actionable insights. Basic concepts include on chain metrics, sentiment analysis, and trading volume. Real world applications range from fraud detection to predicting price movements.

Current trends emphasize DeFi analytics and cross chain data aggregation. Best practices involve using multiple data sources and verifying information. A common misconception is that analytics guarantees profits. It only enhances decision making.

Institutional investors are diving deep into on chain analytics. Stablecoins are disrupting payments. Layer 2 solutions are leading the way.

Ready to see the future? What hidden patterns will you uncover?

Since late December, 2024, an evil magic attack targeted me and my family as well as many people occupying governmental positions. The attack was involving the Antichrist that was on an unreachable island found by me telepathically. Sadly the information about the Antichrist reached some Russian Oligarchs Among which many Jews. And somehow he was contacted by them as well as many other Antichrist Allies among which Royal families and he led the magic attack even though magic mixed with AI and computer technologies. The attack consisted in whispering of the devils, of mankind (Antichrist allies) and jinns. Physical harm was attempted too although so weak for any significant effect for me at least. I hesitated on killing the Antichrist because his appearance is a sign of Judgement Day, however, because of acknowledging that the attack would be too intense for ordinary people that don’t know how to know the difference between inner voice or whispering of the devils I have decided to kill him by requesting that he is burned in the core of the earth and by turning any remains into dust spread in space. He didn’t have only a physical presence though he had an incorporated devil. So it took a while to kill the devil that was isolated in iron coffin first so it assumed a smaller figure while trying to escape and finally God guided me to request that the devil is hit with fireballs over and over again. It was confirmed to me that the devil of the Antichrist was completely burned out. And that the next sign would be the creature coming out of the earth, Ad-Daba as well as the smoke covering all the earth, with which there is a great punishment, and that I would be able to fly too (good for me). I hesitated on spreading the news about the Antichrist to avoid fitnah (confusion and trial). Also because he was never freed out of the island before getting burned out. I am mentioning this because it’s important to know that when God’s punishment comes and when the great signs of Judgement Day (among which what’s mentioned above) would appear the returning to God in belief or in repentance won’t be accepted; so my advise is to do it now.

27:82 An-Naml

‎۞ وَإِذَا وَقَعَ الْقَوْلُ عَلَيْهِمْ أَخْرَجْنَا لَهُمْ دَابَّةً مِنَ الْأَرْضِ تُكَلِّمُهُمْ أَنَّ النَّاسَ كَانُوا بِآيَاتِنَا لَا يُوقِنُونَ

And when the word befalls them, We will bring forth for them a creature from the earth speaking to them, [saying] that the people were, of Our verses, not certain [in faith].

Ha, Meem.

وَالْكِتَابِ الْمُبِينِ

By the clear Book,

إِنَّا أَنْزَلْنَاهُ فِي لَيْلَةٍ مُبَارَكَةٍ ۚ إِنَّا كُنَّا مُنْذِرِينَ

Indeed, We sent it down during a blessed night. Indeed, We were to warn [mankind].

فِيهَا يُفْرَقُ كُلُّ أَمْرٍ حَكِيمٍ

On that night is made distinct every precise matter -

أَمْرًا مِنْ عِنْدِنَا ۚ إِنَّا كُنَّا مُرْسِلِينَ

[Every] matter [proceeding] from Us. Indeed, We were to send [a messenger]

رَحْمَةً مِنْ رَبِّكَ ۚ إِنَّهُ هُوَ السَّمِيعُ الْعَلِيمُ

As mercy from your Lord. Indeed, He is the Hearing, the Knowing.

رَبِّ السَّمَاوَاتِ وَالْأَرْضِ وَمَا بَيْنَهُمَا ۖ إِنْ كُنْتُمْ مُوقِنِينَ

Lord of the heavens and the earth and that between them, if you would be certain.

لَا إِلَٰهَ إِلَّا هُوَ يُحْيِي وَيُمِيتُ ۖ رَبُّكُمْ وَرَبُّ آبَائِكُمُ الْأَوَّلِينَ

There is no deity except Him; He gives life and causes death. [He is] your Lord and the Lord of your first forefathers.

بَلْ هُمْ فِي شَكٍّ يَلْعَبُونَ

But they are in doubt, amusing themselves.

فَارْتَقِبْ يَوْمَ تَأْتِي السَّمَاءُ بِدُخَانٍ مُبِينٍ

Then watch for the Day when the sky will bring a visible smoke.

يَغْشَى النَّاسَ ۖ هَٰذَا عَذَابٌ أَلِيمٌ

Covering the people; this is a painful torment.

رَبَّنَا اكْشِفْ عَنَّا الْعَذَابَ إِنَّا مُؤْمِنُونَ

[They will say], "Our Lord, remove from us the torment; indeed, we are believers."

أَنَّىٰ لَهُمُ الذِّكْرَىٰ وَقَدْ جَاءَهُمْ رَسُولٌ مُبِينٌ

How will there be for them a reminder [at that time]? And there had come to them a clear Messenger.

ثُمَّ تَوَلَّوْا عَنْهُ وَقَالُوا مُعَلَّمٌ مَجْنُونٌ

Then they turned away from him and said, "[He was] taught [and is] a madman."

إِنَّا كَاشِفُو الْعَذَابِ قَلِيلًا ۚ إِنَّكُمْ عَائِدُونَ

Indeed, We will remove the torment for a little. Indeed, you [disbelievers] will return [to disbelief].

يَوْمَ نَبْطِشُ الْبَطْشَةَ الْكُبْرَىٰ إِنَّا مُنْتَقِمُونَ

The Day We will strike with the greatest assault, indeed, We will take retribution.

6:158 Al-An'aam

‎هَلْ يَنْظُرُونَ إِلَّا أَنْ تَأْتِيَهُمُ الْمَلَائِكَةُ أَوْ يَأْتِيَ رَبُّكَ أَوْ يَأْتِيَ بَعْضُ آيَاتِ رَبِّكَ ۗ يَوْمَ يَأْتِي بَعْضُ آيَاتِ رَبِّكَ لَا يَنْفَعُ نَفْسًا إِيمَانُهَا لَمْ تَكُنْ آمَنَتْ مِنْ قَبْلُ أَوْ كَسَبَتْ فِي إِيمَانِهَا خَيْرًا ۗ قُلِ انْتَظِرُوا إِنَّا مُنْتَظِرُونَ

Do they [then] wait for anything except that the angels should come to them or your Lord should come or that there come some of the signs of your Lord? The Day that some of the signs of your Lord will come no soul will benefit from its faith as long as it had not believed before or had earned through its faith some good. Say, "Wait. Indeed, we [also] are waiting."

4:17 An-Nisaa

‎إِنَّمَا التَّوْبَةُ عَلَى اللَّهِ لِلَّذِينَ يَعْمَلُونَ السُّوءَ بِجَهَالَةٍ ثُمَّ يَتُوبُونَ مِنْ قَرِيبٍ فَأُولَٰئِكَ يَتُوبُ اللَّهُ عَلَيْهِمْ ۗ وَكَانَ اللَّهُ عَلِيمًا حَكِيمًا

The repentance accepted by Allah is only for those who do wrong in ignorance [or carelessness] and then repent soon after. It is those to whom Allah will turn in forgiveness, and Allah is ever Knowing and Wise.

4:18 An-Nisaa

‎وَلَيْسَتِ التَّوْبَةُ لِلَّذِينَ يَعْمَلُونَ السَّيِّئَاتِ حَتَّىٰ إِذَا حَضَرَ أَحَدَهُمُ الْمَوْتُ قَالَ إِنِّي تُبْتُ الْآنَ وَلَا الَّذِينَ يَمُوتُونَ وَهُمْ كُفَّارٌ ۚ أُولَٰئِكَ أَعْتَدْنَا لَهُمْ عَذَابًا أَلِيمًا

But repentance is not [accepted] of those who [continue to] do evil deeds up until, when death comes to one of them, he says, "Indeed, I have repented now," or of those who die while they are disbelievers. For them We have prepared a painful punishment.

4:47 An-Nisaa

يَا أَيُّهَا الَّذِينَ أُوتُوا الْكِتَابَ آمِنُوا بِمَا نَزَّلْنَا مُصَدِّقًا لِمَا مَعَكُمْ مِنْ قَبْلِ أَنْ نَطْمِسَ وُجُوهًا فَنَرُدَّهَا عَلَىٰ أَدْبَارِهَا أَوْ نَلْعَنَهُمْ كَمَا لَعَنَّا أَصْحَابَ السَّبْتِ ۚ وَكَانَ أَمْرُ اللَّهِ مَفْعُولًا

O you who were given the Scripture, believe in what We have sent down [to Muhammad], confirming that which is with you, before We obliterate faces and turn them toward their backs or curse them as We cursed the sabbath-breakers. And ever is the decree of Allah accomplished.

4:48 An-Nisaa

إِنَّ اللَّهَ لَا يَغْفِرُ أَنْ يُشْرَكَ بِهِ وَيَغْفِرُ مَا دُونَ ذَٰلِكَ لِمَنْ يَشَاءُ ۚ وَمَنْ يُشْرِكْ بِاللَّهِ فَقَدِ افْتَرَىٰ إِثْمًا عَظِيمًا

Indeed, Allah does not forgive association with Him, but He forgives what is less than that for whom He wills. And he who associates others with Allah has certainly fabricated a tremendous sin.

41:13 Fussilat

‎فَإِنْ أَعْرَضُوا فَقُلْ أَنْذَرْتُكُمْ صَاعِقَةً مِثْلَ صَاعِقَةِ عَادٍ وَثَمُودَ

But if they turn away, then say, "I have warned you of a thunderbolt like the thunderbolt [that struck] 'Aad and Thamud.

‎وَأُخْرَىٰ تُحِبُّونَهَا ۖ نَصْرٌ مِنَ اللَّهِ وَفَتْحٌ قَرِيبٌ ۗ وَبَشِّرِ الْمُؤْمِنِينَ

And [you will obtain] another [favor] that you love - victory from Allah and an imminent conquest; and give good tidings to the believers.

Marty's Bent

J.P. Morgan CEO Jamie Dimon has long been an outspoken skeptic and critic of bitcoin. He has called Bitcoin a speculative asset, a fraud, a pet rock, and has opined that it will inevitably blow up. A couple of years ago, he was on Capitol Hill saying that if he were the government, he would "close it down". Just within the last month, he was on Fox Business News talking with Maria Bartiromo, proclaiming that the U.S. should be stockpiling bullets and rare earth metals instead of bitcoin. It's pretty clear that Jamie Dimon, who is at the helm of the most powerful and largest bank in the world, does not like bitcoin one bit.

Evidence below:

via Bitcoin Magazine

via me

via CNBC

via Trending Politics

Despite Dimon's distinguished disdain for Bitcoin, J.P. Morgan cannot deny reality. The CEO of the largest bank in the world is certainly a powerful man, but no one individual, even in the position that Jamie Dimon is in, is more powerful than the market. And the market has spoken very clearly, it is demanding bitcoin. The Bitcoin ETFs have been the most successful ETFs in terms of pace of growth since their launch. They've accumulated tens of billions of dollars in AUM in a very short period of time. Outpacing the previous record set by the gold ETF, GLD.

Whether or not Jamie Dimon himself likes Bitcoin doesn't matter. J.P. Morgan, as the largest bank in the world and a publicly traded company, has a duty to shareholders. And that duty is to increase shareholder value by any ethical and legal means necessary. Earlier today, J.P. Morgan announced plans to offer clients financing against their Bitcoin ETFs, as well as some other benefits, including having their bitcoin holdings recognized in their overall net worth and liquid assets, similar to stocks, cars, and art, which will be massive for bitcoiners looking to get mortgages and other types of loans.

via Bloomberg

I've talked about this recently, but trying to buy a house when most of your liquid net worth is held in bitcoin is a massive pain in the ass. Up until this point, if you wanted to have your bitcoin recognized as part of your net worth and count towards your overall credit profile, you would need to sell some bitcoin, move it to a bank account, and have it sit there for a certain period of time before it was recognized toward your net worth. This is not ideal for bitcoiners who have sufficient cash flows and don't want to sell their bitcoin, pay the capital gains tax, and risk not being able to buy back the amount of sats they were forced to sell just to get a mortgage.

It's not yet clear to me whether or not J.P. Morgan will recognize bitcoin in cold storage toward their clients' net worth and credit profile, or if this is simply for bitcoin ETFs only. However, regardless, this is a step in the right direction and a validation of something that many bitcoiners have been saying for years. Inevitably, everyone will have to bend the knee to bitcoin. Today, it just happened to be the largest bank in the world. I expect more of this to come in the coming months, years, and decades.

Lyn Alden likes to say it in the context of the U.S. national debt and the fiscal crisis, but it also applies to bitcoin adoption and the need for incumbents to orient themselves around the demands of individual bitcoiners; nothing stops this train.

Corporate Bitcoin Treasuries are Changing Market Dynamics

Leon Wankum revealed how corporate Bitcoin treasuries are fundamentally reshaping business dynamics. Companies can now issue equity to fund operations while preserving their Bitcoin holdings, creating a revolutionary capital structure. Leon highlighted MicroStrategy's position, noting they hold enough Bitcoin to cover dividend payments for over 200 years. This model enables companies to reduce founder dilution since they don't need repeated funding rounds when their treasury appreciates.

"Some companies' Bitcoin treasuries are now worth more than all money they've ever raised." - Leon Wankum

Leon shared examples from his own portfolio companies where this strategy has proven transformative. Public companies have discovered an entirely new business model through strategic dilution that actually increases BTC per share. As Leon explained, this approach allows firms to leverage equity markets for operational funding while their Bitcoin treasury compounds in value, creating a positive feedback loop that benefits both shareholders and the company's long-term sustainability.

Imagina un mundo donde cada peso que gastas es vigilado, registrado y cuestionado. Donde el Estado decide si puedes comprar un café, una manzana o una criptomoneda. No es una distopía de ciencia ficción, es el rumbo que están tomando varios países, mientras otros, como Argentina, dan un giro inesperado hacia la libertad. ¿Quién está ganando esta batalla por el control de tu dinero?

Argentina: "Tus dólares son tuyos" En Argentina, Javier Milei, con su bandera libertaria ondeando, ha dado un paso audaz: desmantelar el control policial sobre el dinero de los ciudadanos. Su lema, "Tus dólares son tuyos", es tan obvio como revolucionario. Después de décadas de corralitos, cepos cambiarios y una inflación que en 2023 alcanzó el 211,4% según el INDEC, Milei apuesta por devolverle al ciudadano el poder sobre su propio capital. Con el país logrando superávit fiscal por primera vez en años (0,2% del PBI en el primer trimestre de 2024), el gobierno ya no necesita espiar cada transacción para exprimir impuestos.

Pero aquí viene lo curioso: encuestas recientes, como una de la consultora Poliarquía, muestran que un 35% de los argentinos aún prefiere que el Estado controle sus finanzas. ¿Masoquismo? ¿Miedo a la libertad? Tal vez sea la costumbre de vivir bajo la lupa. Milei, fiel a su convicción, no solo liberaliza por necesidad económica, sino porque cree que el dinero es tuyo, no del burócrata de turno.

España y el Euro Digital: El ojo que todo lo ve Mientras Argentina afloja las riendas, Europa cabalga en dirección opuesta. En España, el gobierno está reduciendo progresivamente los umbrales para controlar transacciones bancarias. A partir de 2026, cada pago por Bizum —el equivalente ibérico al Pix brasileño— estará bajo escrutinio. Según el Banco de España, en 2024 se realizaron más de 1.200 millones de transacciones por Bizum, moviendo unos 60.000 millones de euros. Ahora, cada una de esas operaciones será un dato más para Hacienda.

Pero no es solo España. La Unión Europea avanza con el Euro Digital, un proyecto que promete ser la pesadilla de cualquier amante de la privacidad. Esta moneda digital, según el Banco Central Europeo, permitirá rastrear cada movimiento, limitar ciertos gastos (¿adiós a compras de cripto o donaciones incómodas?), e incluso programar que el dinero "se oxide". Sí, has leído bien: si no gastas tus euros digitales en un tiempo determinado, podrían perder valor o simplemente desaparecer. Un informe del BCE de 2023 estima que el Euro Digital estará operativo en 2027, y ya hay pruebas piloto en países como Alemania y Francia. ¿Libertad financiera? Más bien un Gran Hermano con esteroides.

Chile: El Estado fisgón y los funcionarios de lujo En Chile, el control monetario también aprieta. El gobierno ha propuesto levantar el secreto bancario, permitiendo que cualquier funcionario del SII pueda husmear en tus cuentas. Además, si haces más de 50 transacciones al mes, el Servicio de Impuestos Internos (SII) pondrá la lupa sobre ti. ¿Y las ferias libres? Esas donde compras tus tomates y zapallos sin complicaciones ahora deberán emitir boletas electrónicas, encareciendo los productos para el ciudadano de a pie. Según la CEPAL, los costos administrativos para pequeños comerciantes podrían aumentar hasta un 15% con estas medidas.

Mientras tanto, el sector público chileno vive en otra galaxia. Funcionarios con sueldos que superan los 5 millones de pesos mensuales (unos 5.500 USD) toman licencias médicas para viajar por el mundo, según denuncias de la Contraloría. Algunos incluso cobran por "turnos" de 17 horas extras diarias o marcan asistencia en dos lugares al mismo tiempo. ¿Y quién paga? Tú, con tus impuestos.

La resistencia: Volver al efectivo o abrazar las cripto Si el Estado quiere controlar cada centavo, ¿qué opciones nos quedan? Una es volver al efectivo, pero no nos engañemos: el dinero fiat, controlado por bancos centrales, pierde valor a largo plazo. En Chile, la inflación acumulada entre 2010 y 2024 fue del 62%, según el INE. Tus billetes de hoy valen menos que los de ayer, y mañana valdrán aún menos.

La otra opción es el mundo cripto, pero no cualquier cripto. Bitcoin, la más conocida, es un titán para almacenar valor, pero para transacciones diarias necesita una segunda capa como Lightning Network, que procesa pagos instantáneos con comisiones ínfimas (menos de 0,01 USD por transacción en 2024). Alternativas como Bitcoin Cash (BCH) o Monero (XMR) ofrecen transacciones rápidas y, en el caso de XMR, un enfoque en la privacidad que hace temblar a los burócratas. Sin embargo, ninguna cripto servirá si los comercios y las personas no las adoptan. En Argentina, por ejemplo, solo el 1,5% de las transacciones minoristas en 2024 usaron criptomonedas, según Chainalysis. La libertad financiera no llega sola: hay que construirla.

El futuro es ahora El dinero es poder, y quien controla el dinero controla tu vida. Mientras Milei en Argentina te devuelve las llaves de tus dólares, en Europa y Chile te atan las manos con leyes, regulaciones y monedas digitales. La pregunta no es si quieres libertad, sino si estás dispuesto a pelear por ella. Usa efectivo, explora cripto, pero sobre todo, no dejes que el Gran Hermano decida por ti. Porque una vez que el Estado mete la mano en tu bolsillo, no la saca nunca.

H100 Group AB, a Swedish publicly listed health technology company, has made the headlines after investing in bitcoin as part of a new financial strategy.

The move has caused a stir in Sweden and beyond, with H100’s stock price rising 40% after the announcement.

The company has bought 4.39 bitcoin for 5 million Norwegian Krone (around $475,000–$492,000).

This is the company’s first foray into the digital asset space and makes H100 Group the first publicly-listed health tech company in Sweden to hold bitcoin as a treasury reserve asset.

The bitcoin was bought at an average price of 1,138,737 NOK (around $108,000) per coin.

The bitcoin purchase is part of H100 Group’s new “Bitcoin Treasury Strategy” to diversify its financial assets and strengthen its balance sheet. Instead of holding idle cash, the company decided to invest in what it sees as a long-term asset.

“This addition to H100’s Bitcoin Treasury Strategy follows an increasing number of tech-oriented growth companies holding bitcoin on their balance sheet,” said CEO Sander Andersen.

“And I believe the values of individual sovereignty highly present in the Bitcoin community aligns well with, and will appeal to, the customers and communities we are building the H100 platform for.”

Andersen said they will “build and hold” bitcoin long-term, viewing it as a savings tool, not a short-term trade.

The market reacted fast. On May 22, the company’s stock went up 39.27%, seeing highs of 1.620 SEK on the Nordic Growth Market.

This helped the company to recover a big part of the losses from the last two months, during which the stock fell 46%.

And now, after the purchase, the firm’s market cap is around $150.46 million.

H100 has said this might not be the only purchase. The company has signed a Letter of Intent (LOI) to set up a convertible loan facility of up to 10 million SEK with an undisclosed investor.

The funds will be used for general corporate purposes and to potentially increase bitcoin holdings. The loan will have a 3-year term and can be converted into shares at 1.3 SEK per share.

If H100’s stock price is more than 33% above the conversion price for more than 60 days, H100 will have the right to force conversion.

The company also announced today that it has successfully raised 21 million SEK ($2.21 million) through a convertible round led by Blockstream founder and CEO Adam Back.

Despite the Bitcoin pivot, H100 Group has made it clear that the core business remains the same.

They will continue to develop AI-powered automation tools and digital platforms to help healthcare providers deliver better services, especially in the health and longevity space.

Andersen said they are committed to healthy living, and adopting a bitcoin strategy is a smarter financial move that aligns with their values.

H100’s move comes as corporate adoption of bitcoin accelerates globally.

According to BitcoinTreasuries over 109 public companies now list bitcoin on their balance sheets. Among those are companies like Twenty One Capital, Strive and Metaplanet.

The Bitcoin world begins what is considered to be its biggest event yet — Bitcoin 2025, a three-day conference taking place May 27-29 at The Venetian Resort in Las Vegas.

With over 30,000 attendees expected, the event will bring together the biggest names in politics, finance, technology and the global Bitcoin community.

Hosted by BTC Inc., Bitcoin 2025 is not just another tech conference — it’s a global gathering that mixes policy, innovation and community under one roof.

It’s where big ideas about the future of money are debated, shared and shaped.

Influential speakers will attend the conference

The conference features a wide range of speakers from Bitcoin experts and educators to political leaders and athletes.

Big names like U.S. Vice President JD Vance, Trump’s Crypto Czar David Sacks, and Senator Cynthia Lummis are among the most anticipated guests.

Vice President Vance is expected to talk about the role of Bitcoin in the national economy. “The resilience of Bitcoin as a financial instrument is a testament to the power of decentralized finance,” he recently said.

Also speaking are Nigel Farage, a well-known voice in European politics and Donald Trump Jr., a supporter of financial freedom through digital currency.

Also, Michael Saylor, Executive Chairman of Strategy will be back on stage to talk about bitcoin as a corporate asset.

There are over 70 speakers on the list including Adam Back (CEO of Blockstream), Jan van Eck (CEO of VanEck) and Bryan Johnson, a futurist known for his work in human longevity and health tech.

Bitcoin 2025 will feature special new programs including Code + Country, a one-day segment on May 27 that explores how freedom, technology and innovation shape modern society.

Speakers like Chris LaCivita (Trump’s 2024 campaign co-CEO) and David Sacks (AI and digital assets advisor) will be talking about how digital tools are changing politics and finance.

Also new this year, is The Art of Freedom, an exhibit that showcases how Bitcoin is impacting the art world.

This museum-style experience allows artists to price and sell their work using bitcoin, connect directly with fans and avoid traditional middlemen.

The first official Bitcoin Conference was in 2019 in San Francisco, after grassroots meetups in 2013 and 2014. Since then, it’s been the biggest annual event in the Bitcoin world.

This year is especially important.

Global economic changes are happening and analysts say the discussions at Bitcoin 2025 will shape the next wave of regulatory reforms and technological standards for Bitcoin and stablecoins.

Bitcoin (BTC) has recently been hovering at around $110,000 with a market cap of $2.12 trillion. Many think the ideas and announcements at the event will impact price and policy.

Bitcoin 2025 is for everyone — long-time Bitcoiners to newcomers to digital assets, with keynotes, panels, massive expo halls and VIP networking.

It’s fun too. There are numerous parties, meetups and side events to connect, making it a place to learn, meet others who share the same interests and help shape the financial world.

The scale and diversity of Bitcoin 2025 make it more than just a Bitcoin event.

It’s a reflection of how far Bitcoin has come — from internet forums to boardrooms and government halls. It’s not just about Bitcoin anymore, it’s about the future of the world.
