2025-06-17 21:01:55- This version introduces the Soroban P2P network, enabling Dojo to relay transactions to the Bitcoin network and share others' transactions to break the heuristic linking relaying nodes to transaction creators.
- Additionally, Dojo admins can now manage API keys in DMT with labels, status, and expiration, ideal for community Dojo providers like Dojobay. New API endpoints, including "/services" exposing Explorer, Soroban, and Indexer, have been added to aid wallet developers.
- Other maintenance updates include Bitcoin Core, Tor, Fulcrum, Node.js, plus an updated ban-knots script to disconnect inbound Knots nodes.
"I want to thank all the contributors. This again shows the power of true Free Software. I also want to thank everyone who donated to help Dojo development going. I truly appreciate it," said Still Dojo Coder.
What's new
- Soroban P2P network. For MyDojo (Docker setup) users, Soroban will be automatically installed as part of their Dojo. This integration allows Dojo to utilize the Soroban P2P network for various upcoming features and applications.
- PandoTx. PandoTx serves as a transaction transport layer. When your wallet sends a transaction to Dojo, it is relayed to a random Soroban node, which then forwards it to the Bitcoin network. It also enables your Soroban node to receive and relay transactions from others to the Bitcoin network and is designed to disrupt the assumption that a node relaying a transaction is closely linked to the person who initiated it.
- Pushing transactions through Soroban can be deactivated by setting
NODE_PANDOTX_PUSH=off
indocker-node.conf
. - Processing incoming transactions from Soroban network can be deactivated by setting
NODE_PANDOTX_PROCESS=off
indocker-node.conf
.
- Pushing transactions through Soroban can be deactivated by setting
- API key management has been introduced to address the growing number of people offering their Dojos to the community. Dojo admins can now access a new API management tab in their DMT, where they can create unlimited API keys, assign labels for easy identification, and set expiration dates for each key. This allows admins to avoid sharing their main API key and instead distribute specific keys to selected parties.
- New API endpoints. Several new API endpoints have been added to help API consumers develop features on Dojo more efficiently:
- New:
/latest-block
- returns data about latest block/txout/:txid/:index
- returns unspent output data/support/services
- returns info about services that Dojo exposes
- Updated:
/tx/:txid
- endpoint has been updated to return raw transaction with parameter?rawHex=1
- The new
/support/services
endpoint replaces the deprecatedexplorer
field in the Dojo pairing payload. Although still present, API consumers should use this endpoint for explorer and other pairing data.
- New:
Other changes
- Updated ban script to disconnect inbound Knots nodes.
- Updated Fulcrum to v1.12.0.
- Regenerate Fulcrum certificate if expired.
- Check if transaction already exists in pushTx.
- Bump BTC-RPC Explorer.
- Bump Tor to v0.4.8.16, bump Snowflake.
- Updated Bitcoin Core to v29.0.
- Removed unnecessary middleware.
- Fixed DB update mechanism, added api_keys table.
- Add an option to use blocksdir config for bitcoin blocks directory.

2025-06-17 21:01:48Carl Rickertsen completely exits his position in Strategy as insiders sell $864 million worth of stock.
As reported by Protos, Carl Rickertsen, a member of Strategy’s board of directors, has fully liquidated his entire shareholding for over $10 million.
Rickertsen’s decision to completely exit his Strategy position marks a sharp shift from his previous investment stance. In 2022, the executive had shown confidence in the company by investing $700,000 in MSTR shares.
On June 13, 2022, Rickertsen purchased $608,000 worth of MSTR stock at $152 per share. Since then, the stock has rallied 152%. However, by 2023, the director had already sold half of his 4,000-share position.
Rickertsen’s approach to managing his holdings has become increasingly aggressive in recent years. Since joining the board in 2019, he has adopted a strategy of immediately liquidating any stock options received.
One example of this tactic occurred on June 2, when he acquired and sold 26,390 MSTR shares on the same day.
As of June 5 this year, Rickertsen reported zero vested Strategy shares, marking the end of his equity involvement with the company.
Rickertsen’s situation is not an isolated case within Strategy. Data from the Securities and Exchange Commission (SEC) reveals a controversial picture. According to information gathered by secform4.com, over the past five years, total insider sales have exceeded purchases by $864 million. This imbalance in insider transactions could raise questions about executives’ confidence in the company’s future.

2025-06-17 21:01:47The new communication protocol aims to improve the industry with measurable advantages in terms of efficiency and security.
A new study conducted by Hashlabs, in collaboration with the SRI (Stratum V2 Reference Implementation) team and figures like Matt Corallo, Alejandro De La Torre and others reveals how the Stratum V2 protocol can increase miner profitability compared to the current Stratum V1 standard, used for over a decade.
Speaking to Atlas21, Gabriele Vernetti, Stratum V2 maintainer, declared:
“This first case study demonstrates how much Stratum V2 can help miners as well, securing and increasing their profits, in addition to the rest of the network. It’s just a first study aimed at demonstrating how decentralization can be aligned with the profit dynamics typical of the mining sector.
In the future we will also focus on the benefits for mining pool operators, who can benefit from the protocol’s efficiency to lower their operating costs (such as those for bandwidth used by their servers).
The feedback has been very positive: this first study was a joint work with various market players, including miners and mining pool operators. As SRI we want to continue working together with the entire community as done in this case, becoming a reference point for all actors interested in innovating the Bitcoin mining field”.
The research, based on controlled tests with two identical ASIC S19k Pro, with stock firmware, demonstrates that Stratum V2 can increase net profits by up to 7.4%. For an industry that often operates with 10% margins, this could represent a substantial competitive advantage.
The V2 protocol reduces various inefficiencies that plague the current system. The latency in block switching, that is the waiting time created when a miner must change block template after a new block has been mined on the network, goes from 325 milliseconds to just 1.42 milliseconds, a speed 228 times higher. This translates to about 4.9 hours of completely wasted hash power less per year.
Another problem of modern mining concerns “stale shares” – proofs of work that arrive too late to be remunerated, often due to network latency or inefficient communication. However, not all stale shares depend on inefficiency problems. On average, about 2% are rejected for expected reasons, such as when the share doesn’t reach the minimum difficulty required by the pool. This value is considered normal in the sector. The remaining 98%, instead, is caused by avoidable delays. With Stratum V1, miners lose between 0.1% and 0.2% of their computing power this way. Stratum V2 with Job Declaration completely eliminates this waste, provided that the miner and the pool node have the same level of connectivity. This step could translate into a net profit increase of up to 2% by fully adopting Stratum V2 with Job Declaration.
In the Stratum V2 protocol, the Job Declaration Client (JDC) is software that allows miners to receive mining jobs directly from their local Bitcoin node, that is the block templates to work on. The JDC communicates directly with the miner’s local node, receiving updated data for new block construction and immediately sending them to the mining software via Stratum V2. This allows miners to receive jobs in real time from their own node, without having to wait for them from the pool, reducing latency and the risk of working on obsolete jobs. Furthermore, if the pool allows it, miners can build custom templates choosing which transactions to include in the block.
The research also highlights an often overlooked aspect: the loss of transaction fees. With the Stratum V1 protocol, miners lose about 0.75% of potential fees for each block due to the delay in receiving new jobs. Considering that about 52,560 blocks are mined each year, this loss per block adds up to a total of about 74 bitcoins per year, equivalent to over $8 million at current prices.
Beyond economic advantages, Stratum V2 solves a critical vulnerability of the current system: hashrate hijacking. The V1 protocol doesn’t encrypt communications, allowing attackers to intercept and steal up to 2% of computing power without the miner noticing. The new protocol eliminates this risk through end-to-end encryption and authentication.
According to the study, by reducing latency, optimizing share sending and improving security, Stratum V2 enables a potential net profit increase of 7.4%, derived exclusively from technical improvements.

2025-06-17 21:01:46French lawmakers are proposing Bitcoin mining as a solution to optimize the national electricity system and make use of surplus energy.
A group of French parliamentarians has introduced an amendment that could turn the country into a European hub for Bitcoin mining, strategically leveraging its energy production capacity.
The legislative proposal aims to assess how mining could be integrated into the French energy system — the largest in Europe — to optimize the management of electricity produced by nuclear power plants.
The amendment to the law on “National Programming and Regulatory Simplification in the Energy Sector” calls on the government to conduct a thorough evaluation of the potential of Bitcoin mining. The initiative represents a pragmatic approach to addressing the issue of excess energy, a key topic for France’s nuclear industry.
France’s energy system, powered by nuclear for over 70% of its needs, often generates electricity surpluses that require efficient management. The proponents of the proposal see mining as an ideal solution to absorb this excess, transforming a potential waste into an economic resource.
The operational flexibility of mining farms offers a unique competitive advantage: machines can be quickly turned on and off based on production and consumption peaks, dynamically adapting to the needs of the electrical grid. This feature makes them particularly suitable for installation near power plants, even in the most remote areas of the country.
The parliamentary proposal highlights how mining could contribute to the revitalization of abandoned industrial sites, creating new opportunities for economic development under the supervision of public authorities.
Lawmakers emphasize the various benefits of this strategy: reducing negative pricing in wholesale markets, relieving the workload on nuclear plants by avoiding frequent modulation cycles that accelerate equipment wear, and absorbing surplus energy that would otherwise go to waste.
The French Association for the Development of Digital Assets (ADAN) collaborated in drafting the amendment, contributing technical expertise and industrial insight to the project. The organization emphasized how low-carbon Bitcoin mining could help strengthen the resilience of the national electricity grid.
The parliamentary report notes that mining in France could represent “an activity tailored to the constraints of the electrical system, absorbing surplus energy and reducing environmental impact” by using power that would otherwise be lost.

2025-06-17 21:01:45Russian authorities uncover 95 Bitcoin mining machines hidden inside a truck stealing electricity from a village.
Law enforcement in the Republic of Buryatia has uncovered an illegal Bitcoin mining operation concealed inside a KamAZ truck. The clandestine facility was siphoning off electricity meant for the local population.
According to the national news agency TASS, the discovery was made during a routine inspection of power lines in the Pribaikalsky district, where inspectors identified an unauthorized connection to a 10-kilovolt line — enough to power an entire village. The criminal operation showed a high level of organization, with sophisticated equipment hidden inside an apparently innocuous transport vehicle.
Source: Babr Mash
Inside the commercial truck, authorities found a fully operational mining center equipped with 95 machines and a portable transformer station. The technical setup suggested careful planning, designed to maximize bitcoin production while minimizing the risk of detection.
Two individuals suspected of involvement in the illegal activity managed to escape in an SUV before law enforcement arrived.
Impact of illegal mining on the local power grid
Buryatenergo, a regional unit of Rosseti Siberia, stressed how unauthorized connections severely compromise the stability of the local power grid. Consequences include voltage drops, overloads, and potential blackouts that disproportionately affect rural communities, already vulnerable in terms of energy access.
The illegal siphoning of electricity for mining creates a domino effect across the entire electrical infrastructure, causing service disruptions for legitimate users and increasing maintenance costs for grid operators.
Government restrictions on mining
The Russian government has implemented various restrictions on cryptocurrency mining in several regions of the country. In Buryatia, mining is banned from November 15 to March 15 due to seasonal energy shortages. Only companies registered in specific districts such as Severo-Baikalsky and Muisky are allowed to operate outside this period.
Federal restrictions were further tightened in December 2024, when Russia announced a ban on mining during peak energy months in multiple regions, including Dagestan, Chechnya, and parts of eastern Ukraine under Russian control. Since April, a total ban has been in effect in the southern region of Irkutsk.
Despite these restrictions, some Russian companies continue to operate legally in the sector. BitRiver, one of the country’s leading operators, takes advantage of the region’s low-cost energy, having launched its first and largest facility in 2019 in the city of Bratsk.

2025-06-17 17:23:55A sede do ProtonMail está localizada na Suíça, um país conhecido por suas leis rigorosas de privacidade, embora a empresa tenha enfrentado alguns desafios, como ataques DDoS e pressão do governo suíço, ela continua comprometida em fornecer um serviço seguro e privado aos seus usuários.
O ProtonMail foi fundado em 2014 por um grupo de cientistas do CERN (Organização Europeia para Pesquisa Nuclear) que queriam criar uma plataforma de e-mail segura e privada que usasse criptografia de ponta a ponta. O objetivo era oferecer aos usuários uma alternativa aos serviços de e-mail tradicionais que frequentemente violam a privacidade dos usuários.A equipe fundadora incluía Andy Yen, Jason Stockman e Wei Sun, todos com formação em física e matemática.
Ao longo dos anos, o ProtonMail lançou vários recursos adicionais, incluindo aplicativos móveis para iOS e Android, integração com Tor e a possibilidade de enviar e-mails criptografados para usuários de outros provedores de e-mail. O ProtonMail também lançou uma VPN (rede privada virtual) chamada ProtonVPN, que segue o mesmo compromisso com a privacidade e segurança dos usuários.
A criptografia de ponta a ponta utilizada pelo ProtonMail assegura a proteção de todas as mensagens de seus usuários. O processo de criptografia ocorre no dispositivo do remetente antes do envio das mensagens aos servidores da ProtonMail, onde elas são armazenadas em formato criptografado. Quando o destinatário abre a mensagem, ela é descriptografada no dispositivo do destinatário, garantindo que somente o destinatário possa ler o conteúdo da mensagem. Isso significa que, mesmo que os servidores da ProtonMail sejam violados, as mensagens dos usuários permanecerão seguras e protegidas.
O ProtonMail oferece suporte à autenticação de dois fatores usando chaves de segurança YubiKey. Isso adiciona uma camada extra de segurança ao login da conta do ProtonMail, pois um invasor precisaria não apenas da senha, mas também da chave física para acessar a conta do usuário. A YubiKey é uma opção popular para autenticação de dois fatores, pois é fácil de usar e oferece proteção adicional contra-ataques de phishing e keylogging. O ProtonMail também suporta outras opções de autenticação de dois fatores, aplicativos de autenticação, como o Aegis Authenticator.
Outra funcionalidade importante é a proteção contra phishing e spam. O ProtonMail utiliza algoritmos avançados de filtragem para identificar e bloquear mensagens maliciosas antes que elas cheguem à caixa de entrada do usuário. Isso ajuda a reduzir a quantidade de spam recebida e a proteger contra-ataques de phishing, que tentam enganar o usuário a fornecer informações pessoais.
Passo a passo instalação do aplicativo protonmail no Android:
-
Baixe e instale o aplicativo protonmail em seu dispositivo móvel no F-droid ou obtainium.
-
Clique em "Criar nova conta" se você ainda não tiver uma conta ProtonMail, ou clique em "Fazer login" se já tiver uma conta.
-
Se você está criando uma nova conta, preencha os campos de registro, incluindo seu endereço de e-mail desejado e uma senha forte.
-
Depois de criar ou fazer login em sua conta, você pode usar o ProtonMail em seu dispositivo Android para enviar e receber e-mails seguros e protegidos.
Lembre-se de que, para garantir a privacidade e a segurança de suas informações, é importante usar uma senha forte e habilitar a autenticação de dois fatores. Utilize o Tor para acessar seu e-mail no site onion e considere usar uma VPN.
No Relatório de Transparência do ProtonMail, em muitos casos, a única informação que eles puderam fornecer foi um e-mail de recuperação (opcional na criação da conta) ou o IP que acessou o e-mail.
A própria ProtonMail recomenda o uso do Tor para acesso anônimo ao serviço. Se um juiz exigir a coleta do seu IP, a Proton não terá essa informação se você acessar seu e-mail via o site onion pelo Tor.
Se você é uma pessoa em situação de risco, como um ativista ou alguém que pode ser perseguido por diversos motivos, é essencial tomar medidas excepcionais: 1. Pague pelo serviço com Bitcoin. 2. Não use informações que possam identificá-lo ao se registrar. 3. Utilize o Tor, ou uma VPN, sempre que acessar o ProtonMail.

2025-06-17 21:01:44The Brazilian government has abolished the Bitcoin tax exemption for small investors and introduced a flat 17.5% tax rate on all crypto capital gains.
Brazil has officially ended the tax-free period for small digital asset investors, introducing a flat 17.5% rate on all profits from cryptocurrency sales. The decision was formalized through Provisional Measure 1303, part of the government’s strategy to increase tax revenues from financial markets.
Until now, Brazilian residents selling up to 35,000 Brazilian reais (around $6,300) in cryptocurrencies per month were completely exempt from income tax. Profits exceeding this threshold were subject to progressive taxation, starting at 15% and reaching up to 22.5% for amounts over 30 million reais.
The new flat rate, which took effect on June 12, removes all exemptions and applies uniformly to every investor, regardless of the size of their transactions, according to local outlet Portal do Bitcoin.
While small-scale investors will now face a higher tax burden, high-net-worth individuals might actually benefit. Under the previous system, large transactions were taxed between 17.5% and 22.5%. With the new flat 17.5% rate, many high-profile investors will see their effective tax liability reduced.
Under the new rules, taxes will be calculated quarterly, with investors allowed to offset losses from the previous five quarters. However, starting in 2026, the time frame for claiming losses will be shortened.
Last March, Brazilian lawmakers also proposed a bill allowing employers to partially pay workers in cryptocurrency. According to the draft, crypto payments could not exceed 50% of an employee’s salary.
Full payment in cryptocurrencies would only be allowed for foreign workers or contractors, and only under specific conditions set by the Brazilian Central Bank. The bill prohibits full crypto payment for standard employees.

2025-06-17 21:01:43VanEck analyst Matthew Sigel warns of growing risks for Bitcoin treasury companies as their stock prices approach NAV.
Matthew Sigel, Head of Digital Assets Research at VanEck, has sounded the alarm for companies that have adopted Bitcoin-based treasury strategies.
No public BTC treasury company has traded below its Bitcoin NAV for a sustained period.
But at least one is now approaching parity.
As some of these companies raise capital through large at-the-market (ATM) programs to buy BTC, a risk is emerging: If the stock trades at or near…
— matthew sigel, recovering CFA (@matthew_sigel) June 16, 2025
In a post on X, Sigel highlighted an emerging issue in the sector of companies holding Bitcoin treasuries. Until now, no public company with a Bitcoin treasury has ever traded below its own Net Asset Value (NAV) for extended periods. The NAV represents the net value of a company’s assets (such as bitcoin and cash) minus its liabilities, divided by the number of outstanding shares — essentially indicating the real value of each share based on the company’s holdings. However, at least one of these companies (Semler Scientific) is now dangerously approaching breakeven.
The core of the issue lies in the capital-raising mechanism. Many of these companies rely on large-scale at-the-market (ATM) programs to acquire bitcoin, but when the stock price nears the NAV, this strategy can shift from creating value to destroying it.
The risk for shareholders
Under normal market conditions, companies like Semler Scientific and Strategy trade at a premium to the value of the bitcoin they hold. This means investors are willing to pay more for the company’s stock than the simple value of its bitcoin treasury.
However, when a company’s stock price approaches or falls below its NAV, the situation becomes problematic, according to Sigel. Issuing new shares at these levels not only dilutes the value for existing shareholders but can also become extractive, as management continues to raise capital while benefiting more than shareholders.
Proposed solutions
Sigel suggested several measures for companies pursuing Bitcoin treasury strategies. His recommendations include implementing preventive safeguards while stock premiums still exist. Notably, he proposes announcing a pause in ATM issuances if the stock trades below 0.95 times NAV for ten or more consecutive trading days. Additionally, Sigel advises prioritizing buybacks when bitcoin appreciates but the company’s equity does not reflect that increase.
Lessons from Bitcoin miners’ past
The VanEck analyst pointed out that similar situations have occurred in the Bitcoin mining sector, marked by persistent equity issuances and disproportionate executive compensation. To avoid repeating those mistakes, Sigel suggests that executive pay should be tied to growth in NAV per share, not the size of the Bitcoin position or the total number of outstanding shares.
Sigel concluded:
“Once you are trading at NAV, shareholder dilution is no longer strategic. It is extractive. Boards and shareholders should act with discipline now, while they still have the benefit of optionality.”

2025-06-17 21:01:42The banking giant is exploring an expansion of its blockchain services, focusing on digital payments and currencies.
JPMorgan Chase has filed a new trademark application for the name “JPMD.” The filing was submitted on June 15 to the United States Patent and Trademark Office (USPTO).
The application, filed by JPMorgan Chase Bank, N.A., covers a broad range of services related to digital assets and blockchain technology. These include the issuance of digital currencies, electronic payment processing, and financial custody services — all of which suggest a possible new stablecoin initiative for JPMorgan.
Experience with JPM Coin
This move wouldn’t be JPMorgan’s first foray into blockchain-based finance. The bank already operates JPM Coin, a dollar-pegged stablecoin used to enable instant transactions between institutional clients. The token runs on Quorum, a private blockchain network developed in-house by JPMorgan and based on Ethereum’s technology.
The registration of the JPMD trademark comes as JPMorgan and other major U.S. banks are considering a collaborative stablecoin project through their jointly owned entities: Early Warning Services and The Clearing House.
Similarly, corporations like Walmart and Amazon are mulling the creation of their own stablecoins.

2025-06-17 21:01:41A new study by Kraken reveals how cryptocurrency investors perceive security as the main challenge in self-managing their digital assets.
According to The Block, a recent survey conducted by crypto exchange Kraken found that nearly half of respondents consider themselves the primary risk factor for their own crypto security. The research, which surveyed 789 participants, highlights that 48% of users see their own actions as the greatest threat to their investments in digital assets, surpassing concerns about external theft or fraud.
Kraken’s report underlines how personal responsibility in security management forces users to take full control of their digital funds. However, the study suggests that this autonomy can also become a source of anxiety for many investors.
Nick Percoco, Chief Security Officer at Kraken, commented on the findings, noting that “a lack of confidence in personal crypto security is capping the growth of the industry.” According to Percoco, unlocking the full potential of cryptocurrencies will require users to embrace self-custody and consistently invest in strong security habits.
Technologies to strengthen security
Despite the concerns highlighted in the study, 31% of participants expressed optimism about future technologies that could improve crypto security. Among the most promising solutions identified:
- advanced biometric systems for user authentication;
- multi-factor authentication to secure wallet access;
- AI-based fraud detection systems to prevent attacks.
Data and case studies
Kraken’s research emerges in a context where security threats remain a pressing reality. FBI data shows that in 2024, nearly 150,000 reports of crypto-related internet fraud resulted in $9.3 billion in losses. Older users, particularly those over 60, proved especially vulnerable, accounting for $3 billion in crypto-related financial fraud losses on their own.

Flash Releases Free Bitcoin Invoicing Tool with No Fees, KYC, or CustodyFlash, a Bitcoin payment platform, just announced it has launched Flash Invoicing, a completely free, non-custodial, and KYC-free Bitcoin invoicing tool. Designed for freelancers, the platform allows users to send professional invoices without platform fees, identity checks, or third party custody.
According to Deel, a crypto payments company for freelancers, Bitcoin is the most used cryptocurrency in the world for payments. Despite this growth, many freelancers continue to use basic methods such as pasting Bitcoin addresses into PDFs or emails. Some rely on custodial platforms that deduct fees or require identity verification, which can affect both earnings and data privacy.
“We’ve seen too many people paste BTC addresses into documents and call it invoicing,” said the CEO of Flash Pierre Corbin. “It’s messy. It’s risky. And it’s time for something better.”
Flash Invoicing Features:
- 0% platform fees: no subscriptions or commission
- Non-custodial: Bitcoin goes straight to the user’s wallet
- No KYC: users maintain full privacy
- Professional output: branded PDFs and secure payment links
- Integrated dashboard: manage payments, clients, and revenue
- Works with Flash ecosystem: including Stores, Donations, Paywalls, and POS
Many Bitcoin invoicing tools charge a percentage per transaction or require a subscription. As a result, freelancers often lose part of their income simply to issue an invoice and receive payment. Flash is aiming to solve this issue.
“Freelancers work hard enough. The last thing they need is a platform skimming off their earnings,” said Corbin. “That’s why we dropped our fee from 1.5% to 0% — and launched the first invoicing tool that’s truly free, without compromising on privacy or control.”
Flash Invoicing allows users to accept Bitcoin payments without relinquishing control, privacy, or revenue. It is integrated with the broader Flash suite, enabling users to manage invoicing alongside features such as setting up stores, receiving donations, or gating premium content.
“As a freelancer myself, I love using the Flash invoicing feature,” stated a freelancer & Flash user. ”It keeps all my clients in one place, allows me to easily edit invoices and track payments. Much more professional than sending a lightning address in the footer of a PDF invoice.”

2025-06-17 21:01:35Japanese investment firm Metaplanet has announced a massive $5.4 billion plan to increase its bitcoin holdings to 210,000 BTC by the end of 2027 — that’s about 1% of the total bitcoin supply.
Metaplanet on X
The Tokyo-listed company is accelerating its already aggressive bitcoin plan, with CEO Simon Gerovich calling the initiative “Asia’s largest-ever equity raise to buy Bitcoin — again!”
The company’s new capital raise, called the “555 Million Plan”, involves issuing 555 million shares through moving strike warrants. That’s basically a type of option where people can buy shares later, and the price they pay depends on the stock’s price at that time.
So with moving strike warrants, the price at which people can buy the stock goes up or down depending on how the company’s stock is doing. It gives investors more flexibility — and it can make the warrants more attractive — because they don’t get stuck with a bad deal if the stock price drops.
This way the company can raise capital gradually over the next 2 years without impacting the stock market and existing shareholders.
The funds raised will be used to buy bitcoin, with some to redeem bonds and other income-generating strategies like selling put options.
This is a big step up from Metaplanet’s previous targets. Initially aiming to reach 10,000 BTC by the end of 2025, the company now plans to reach:
- 30,000 BTC by end of 2025
- 100,000 BTC by end of 2026
- 210,000 BTC by end of 2027
The Japanese investment firm hopes to be in the “Bitcoin 1% club” which means holding at least 1% of the total 21 million bitcoin supply.
Metaplanet bitcoin targets
Metaplanet is already making good progress. As of June 2025, the company holds 8,888 BTC, acquired at a cost of about ¥122.2 billion (around $849 million) and has already reached 89% of its original 10,000 BTC target for 2025.
This comes after the success of the company’s previous “210 Million Plan” which raised ¥93.3 billion ($650 million) in 60 trading days by issuing 210 million shares.
During that time, the company’s bitcoin holdings grew from 1,762 BTC to 7,800 BTC and the BTC Yield (a key performance metric showing growth in bitcoin per share) increased by 189%.
Year to date the BTC Yield is 225.4%.
Metaplanet’s BTC Yield graph
The stock has reflected this momentum, up 275% since early 2025 and 1,619% over the past year.
Metaplanet’s stock price chart — TradingView
Metaplanet is now one of the most actively traded stocks in Japan and has become a top-ten corporate bitcoin holder globally, recently surpassing Block Inc., the company founded by Jack Dorsey.
Metaplanet sees this as part of a bigger shift in capital markets.
By being a “bitcoin treasury vehicle” listed on the Tokyo Stock Exchange, it aims to offer investors exposure to bitcoin through regulated equity markets. This is especially useful in Japan where retail investors are often restricted from accessing bitcoin directly.
“Bitcoin is repricing the global cost of capital,” the company said in a statement. “Through our 555 Million Plan, Metaplanet is doubling down on a high-conviction, equity-driven capital markets strategy to accelerate our Bitcoin accumulation trajectory.”

2025-06-17 21:01:14The Barcelona Cyphers Conference (BCC8333), the city’s first biggest bitcoin-themed event, transforms a historic building in the central born district of the Catalan capital into a hub for bitcoin enthusiasts and cypherpunks. Named after the port bitcoin nodes use to sync the timechain (8333), this inaugural event delivers high-signal discussions and practical applications of decentralized technology, uniting over 100 attendees from Spain, Europe, and beyond.
Venue and Atmosphere
Set in a 17th-century palace that doubles as a flamenco venue, Palau Dalmases blends historical elegance with a creative, almost rebellious vibe. The unique setting fosters deep conversations, hands-on workshops, and genuine connections, prioritizing substance over spectacle. The spectacular courtyard serves as a lively backdrop for collaboration and sparking chats that resonates with the event’s freedom/privacy-oriented ethos.
Lightning Network Integration
BCC8333 embedds Bitcoin’s Lightning Network (LN) into its core, emphasizing privacy and scalable technology. Two on-site bars accept LN payments for drinks, demonstrating fast, low-cost bitcoin transactions in action.
But the usage of Lightning Network extends beyond just ‘refreshments’.
· Chain Duel: This simple yet engaging game has many BCC8333 participants send sats via LN to enter, compete, and have fun for the two days of the event. A large-screen tournament on the main stage amplifies the excitement, showcasing one more practical case for LN in the bitcoin ecosystem with a nice bounty, i.e. winners claiming the collected sats.
· Thematic sessions and practical workshops on wallets, vending machines, and Nostr highlight LN’s role in bitcoin adoption, while touching on the importance of privacy vs. scalable transactions.
While the overall adoption in Barcelona’s local establishments outside the venue remains rather limited, attendees find a nearby street with vivid graffiti dedicated to bitcoin, and in a practical way, whenever possible, swap sats for fiat among themselves when direct payments aren’t possible.
Selected Highlights
The agenda balances intense sessions with networking breaks, ensuring space for reflection and collaboration. Some of the key sessions include:
· Future of Private Transactions (English, Max Hillebrand).
· Miniscripts Roundtable (English, Edouard from Liana, Landabaso from Rewind, Francesco from BitVault, Yuri da Silva from Great Wall).
· Sovereign Hardware Tools (English, Wesatoshi).
· Debate: Future of Lightning (Spanish, mixed attendees).
· Op_return Debate (English, Peter Todd, Unhosted Marcellus, Lunaticoin).
Recordings from the main stage and additional coverage by Juan Cienfuegos, host of the BitCorner Podcast, will soon be available online (X: @BCC833, @TheJuanSC).
Why BCC8333 Stood Out
· Local Maxis: vibrant and well-organized approach shines through, with local bitcoiners as organizers of the event (Spanish and expats) bringing their best PoW to the table.
· Focused Discussions: Free of hype and influencers, BCC8333 prioritizes signal over noise, diving into critical topics like privacy, nodes, wallets, P2P tools, decentralized mining, and Nostr.
· Community Vibe: The smaller crowd enables authentic connections, fostering a tight-knit community of freedom-tech enthusiasts committed to sovereignty.
BCC8333 is a powerful testament to the cypherpunk spirit, blending bitcoin and privacy to fuel innovation. From LN-powered interactions to thought-provoking talks, the event underscores the strength of a community dedicated to building decentralized solutions. Congratulations to the organizers, contributors, volunteers, and attendees for making this conference a standout moment in the year’s lineup of bitcoin-themed events.

2025-06-17 18:01:40Carl Rickertsen completely exits his position in Strategy as insiders sell $864 million worth of stock.
As reported by Protos, Carl Rickertsen, a member of Strategy’s board of directors, has fully liquidated his entire shareholding for over $10 million.
Rickertsen’s decision to completely exit his Strategy position marks a sharp shift from his previous investment stance. In 2022, the executive had shown confidence in the company by investing $700,000 in MSTR shares.
On June 13, 2022, Rickertsen purchased $608,000 worth of MSTR stock at $152 per share. Since then, the stock has rallied 152%. However, by 2023, the director had already sold half of his 4,000-share position.
Rickertsen’s approach to managing his holdings has become increasingly aggressive in recent years. Since joining the board in 2019, he has adopted a strategy of immediately liquidating any stock options received.
One example of this tactic occurred on June 2, when he acquired and sold 26,390 MSTR shares on the same day.
As of June 5 this year, Rickertsen reported zero vested Strategy shares, marking the end of his equity involvement with the company.
Rickertsen’s situation is not an isolated case within Strategy. Data from the Securities and Exchange Commission (SEC) reveals a controversial picture. According to information gathered by secform4.com, over the past five years, total insider sales have exceeded purchases by $864 million. This imbalance in insider transactions could raise questions about executives’ confidence in the company’s future.

2025-06-17 17:37:05O protocolo Matrix é um sistema de comunicação descentralizado de código aberto que fornece uma plataforma para mensageiros descentralizados. O Element foi lançado em 2014 como uma implementação do protocolo Matrix, originalmente conhecido como Riot.im , A ideia do Element nasceu quando Matthew Hodgson e Amandine Le Pape, dois desenvolvedores de software, decidiram criar uma plataforma de comunicação aberta e segura, que permitisse aos usuários terem total controle sobre suas informações. Eles acreditavam que a internet deveria ser um lugar onde as pessoas pudessem se comunicar livremente, sem se preocupar com a privacidade de suas informações.
O Element é um aplicativo de chat gratuito e de código aberto disponível em várias plataformas, incluindo desktop, web e aplicativos móveis. Ele oferece criptografia de ponta a ponta, o que significa que as mensagens são protegidas e só podem ser lidas pelo remetente e pelo destinatário. Além disso, o Element é descentralizado, o que significa que ele não é controlado por uma única entidade, mas sim por uma rede global de servidores.
O Element é amplamente utilizado por indivíduos e empresas que desejam ter uma comunicação segura e privada. É frequentemente usado por equipes de projetos, organizações sem fins lucrativos e grupos ativistas que precisam compartilhar informações confidenciais e se comunicar de forma segura. O Element também é conhecido por seu recurso de salas públicas, que permite que os usuários se juntem a grupos de discussão sobre vários tópicos de interesse.
Uma das principais vantagens do Element é sua arquitetura descentralizada. Ao contrário das plataformas de mensagens convencionais que centralizam os dados em seus próprios servidores, o Element utiliza uma rede descentralizada, distribuindo as informações em diversos servidores espalhados pelo mundo. Isso significa que os dados dos usuários são menos suscetíveis a ataques cibernéticos e invasões, já que não são centralizados em um único ponto vulnerável.
Para usar o Element, normalmente os usuários precisam se registrar em um servidor Matrix. Existem várias opções disponíveis, incluindo servidores públicos e privados. No entanto, outra opção é criar um servidor próprio para usar o Element.
O Element também utiliza criptografia de ponta a ponta para proteger as mensagens e arquivos trocados entre os usuários. Isso significa que apenas o remetente e o destinatário das mensagens podem ler o conteúdo, garantindo que as informações permaneçam seguras e privadas.
Outra vantagem do Element é sua ampla variedade de recursos, incluindo videochamadas criptografadas, compartilhamento de tela e integração com outros serviços, como calendários e aplicativos de produtividade. Isso torna o Element uma plataforma completa de comunicação e colaboração, adequada para uso pessoal e empresarial.
O Element também é fácil de usar e possui uma interface intuitiva e personalizável. Os usuários podem personalizar a aparência do aplicativo e acessar diferentes configurações e recursos com apenas alguns cliques.

Flash Releases Free Bitcoin Invoicing Tool with No Fees, KYC, or CustodyFlash, a Bitcoin payment platform, just announced it has launched Flash Invoicing, a completely free, non-custodial, and KYC-free Bitcoin invoicing tool. Designed for freelancers, the platform allows users to send professional invoices without platform fees, identity checks, or third party custody.
According to Deel, a crypto payments company for freelancers, Bitcoin is the most used cryptocurrency in the world for payments. Despite this growth, many freelancers continue to use basic methods such as pasting Bitcoin addresses into PDFs or emails. Some rely on custodial platforms that deduct fees or require identity verification, which can affect both earnings and data privacy.
“We’ve seen too many people paste BTC addresses into documents and call it invoicing,” said the CEO of Flash Pierre Corbin. “It’s messy. It’s risky. And it’s time for something better.”
Flash Invoicing Features:
- 0% platform fees: no subscriptions or commission
- Non-custodial: Bitcoin goes straight to the user’s wallet
- No KYC: users maintain full privacy
- Professional output: branded PDFs and secure payment links
- Integrated dashboard: manage payments, clients, and revenue
- Works with Flash ecosystem: including Stores, Donations, Paywalls, and POS
Many Bitcoin invoicing tools charge a percentage per transaction or require a subscription. As a result, freelancers often lose part of their income simply to issue an invoice and receive payment. Flash is aiming to solve this issue.
“Freelancers work hard enough. The last thing they need is a platform skimming off their earnings,” said Corbin. “That’s why we dropped our fee from 1.5% to 0% — and launched the first invoicing tool that’s truly free, without compromising on privacy or control.”
Flash Invoicing allows users to accept Bitcoin payments without relinquishing control, privacy, or revenue. It is integrated with the broader Flash suite, enabling users to manage invoicing alongside features such as setting up stores, receiving donations, or gating premium content.
“As a freelancer myself, I love using the Flash invoicing feature,” stated a freelancer & Flash user. ”It keeps all my clients in one place, allows me to easily edit invoices and track payments. Much more professional than sending a lightning address in the footer of a PDF invoice.”

2025-06-17 16:02:01The banking giant is exploring an expansion of its blockchain services, focusing on digital payments and currencies.
JPMorgan Chase has filed a new trademark application for the name “JPMD.” The filing was submitted on June 15 to the United States Patent and Trademark Office (USPTO).
The application, filed by JPMorgan Chase Bank, N.A., covers a broad range of services related to digital assets and blockchain technology. These include the issuance of digital currencies, electronic payment processing, and financial custody services — all of which suggest a possible new stablecoin initiative for JPMorgan.
Experience with JPM Coin
This move wouldn’t be JPMorgan’s first foray into blockchain-based finance. The bank already operates JPM Coin, a dollar-pegged stablecoin used to enable instant transactions between institutional clients. The token runs on Quorum, a private blockchain network developed in-house by JPMorgan and based on Ethereum’s technology.
The registration of the JPMD trademark comes as JPMorgan and other major U.S. banks are considering a collaborative stablecoin project through their jointly owned entities: Early Warning Services and The Clearing House.
Similarly, corporations like Walmart and Amazon are mulling the creation of their own stablecoins.

2025-06-17 15:22:49A rede Bitcoin é formada por uma infraestrutura descentralizada feita de dispositivos chamados nós. Esses nós têm um papel crucial na validação, verificação e manutenção do sistema, assegurando a segurança e a integridade do blockchain ou timechain. Ao contrário dos sistemas tradicionais, onde uma autoridade central controla as operações, a rede Bitcoin requer a colaboração de milhares de nós pelo mundo, promovendo descentralização e transparência.
Na rede Bitcoin, um nó é qualquer computador que está conectado ao sistema e participa do armazenamento, validação ou distribuição de informações. Esses dispositivos rodam o software do Bitcoin e podem operar em diferentes níveis de participação, desde tarefas básicas de transmissão de dados até a validação total de transações e blocos.
Existem dois tipos principais de nós:
Nós completos (full nodes):
Armazenam uma cópia total do blockchain ou timechain.
Validam e verificam todas as transações e blocos de acordo com as regras do protocolo.
Asseguram a segurança da rede ao rejeitar transações inválidas ou tentativas de fraude.
Nós leves (light nodes):
Armazenam somente partes do blockchain ou timechain, não a estrutura inteira.
Confiam em nós completos para obter dados sobre o histórico de transações.
São mais rápidos e menos exigentes em termos de recursos, mas dependem de terceiros para validação completa.
Os nós conferem se as transações enviadas seguem as regras do protocolo, como assinaturas digitais válidas e ausência de gastos duplos.
Somente transações válidas são enviadas para outros nós e incluídas no próximo bloco.
Os nós completos mantêm uma cópia atualizada de todo o histórico de transações da rede, garantindo integridade e transparência e se houver discrepâncias, os nós seguem a cadeia mais longa e válida, evitando manipulações.
Os nós transmitem informações de transações e blocos para outros nós na rede. Esse processo assegura que todos os participantes estejam sincronizados e atualizados.
Como a rede Bitcoin é composta por milhares de nós independentes, é quase impossível que um único agente controle ou modifique o sistema.
Os nós também protegem contra ataques ao validar informações e barrar tentativas de fraudes.
Os nós completos são muito importantes, pois atuam como auditores independentes. Eles não precisam de terceiros e podem verificar todo o histórico de transações diretamente.
Ao manterem uma cópia completa do blockchain ou timechain, esses nós permitem que qualquer pessoa valide transações sem depender de intermediários, promovendo clareza e liberdade financeira.
Além disso, os nós completos:
Reforçam a resistência à censura: Nenhum governo ou entidade pode excluir ou alterar dados registrados no sistema.
Preservam a descentralização: Quanto mais nós completos existirem, mais segura e forte será a rede.
Aumentam a confiança no sistema: Os usuários podem confirmar de forma independente se as regras estão sendo seguidas.
Apesar de seu valor, operar um nó completo pode ser difícil, pois exige espaço de armazenamento, processamento e largura de banda. À medida que o blockchain ou timechain cresce, os requisitos técnicos aumentam, o que pode dificultar a participação de usuários comuns.
Para resolver esse problema, a comunidade busca sempre soluções, como melhorias no software e aumento na escalabilidade, para facilitar o acesso à rede sem prejudicar a segurança.
Resumindo, os nós são a base da rede Bitcoin, desempenhando funções importantes na validação, verificação e distribuição de transações. Eles garantem a descentralização e a segurança do sistema, permitindo que os participantes operem de forma confiável sem depender de intermediários.
Particularmente, os nós completos têm um papel crucial na proteção da integridade do blockchain ou timechain, tornando a rede Bitcoin resistente a censura e manipulação.
Embora operar um nó possa exigir recursos técnicos, seu efeito na preservação da liberdade financeira e na confiança do sistema é inestimável. Assim, os nós continuam sendo elementos essenciais para o sucesso e a durabilidade do Bitcoin.

2025-06-17 17:35:10Desde a sua criação em 2008, Bitcoin tem sido visto como um desafio direto ao sistema bancário tradicional. Desenvolvido como uma alternativa descentralizada ao dinheiro fiduciário, Bitcoin oferece uma forma de armazenar e transferir valor sem depender de bancos, governos ou outras instituições financeiras. Essa característica faz com que seja considerado um símbolo de resistência contra um sistema financeiro que, ao longo do tempo, tem sido marcado por crises, manipulações e restrições impostas aos cidadãos.
Crise financeira de 2008 e o nascimento de Bitcoin
Bitcoin surgiu em resposta à crise financeira de 2008, um colapso que revelou as falhas do sistema bancário global. Bancos centrais imprimiram grandes quantidades de dinheiro para resgatar instituições financeiras irresponsáveis, enquanto milhões de pessoas perderam as suas casas, poupanças e empregos. Nesse contexto, Bitcoin foi criado como um sistema financeiro alternativo, onde não existe uma entidade central com o poder de manipular a economia em benefício próprio.
No primeiro bloco da blockchain ou timechain de Bitcoin, Satoshi Nakamoto incluiu a seguinte mensagem:
"The Times 03/Jan/2009 Chancellor on brink of second bailout for banks."
Essa frase, retirada de uma manchete de jornal da época, simboliza a intenção de Bitcoin de oferecer um sistema financeiro fora do controlo dos bancos e dos governos.
Principais razões pelas quais Bitcoin resiste ao sistema bancário
Descentralização: Ao contrário do dinheiro emitido por bancos centrais, Bitcoin não pode ser criado ou controlado por nenhuma entidade específica. A rede de utilizadores valida as transações de forma transparente e independente.
Oferta limitada: Enquanto os bancos centrais podem imprimir dinheiro sem limites, causando inflação e desvalorização da moeda, Bitcoin tem uma oferta fixa de 21 milhões de unidades, tornando-o resistente à depreciação artificial.
Impossibilidade de censura: Bancos podem bloquear contas e impedir transações a qualquer momento. Com Bitcoin, qualquer pessoa pode enviar e receber fundos sem pedir permissão a terceiros.
Autocustódia: Em vez de confiar os seus fundos a um banco, os utilizadores de Bitcoin podem armazenar as suas próprias moedas, sem risco de congelamento de contas ou falências bancárias.
Conflito entre bancos e Bitcoin
Ataques mediáticos: Grandes instituições financeiras frequentemente classificam Bitcoin como arriscado, volátil ou inútil, tentando desincentivar a sua adoção.
Regulação e repressão: Alguns governos, influenciados pelo setor bancário, têm criado restrições ao uso de Bitcoin, dificultando a sua compra e venda.
Criação de alternativas centralizadas: Muitos bancos centrais estão a desenvolver moedas digitais (CBDCs) que mantêm o controlo do dinheiro digital, mas sem oferecer a liberdade e a descentralização de Bitcoin.
Resumindo, o Bitcoin não é apenas uma moeda digital, mas um movimento de resistência contra um sistema financeiro que falhou repetidamente em proteger o cidadão comum. Ao oferecer uma alternativa descentralizada, transparente e resistente à censura, Bitcoin representa a liberdade financeira e desafia o monopólio dos bancos sobre o dinheiro. Enquanto o sistema bancário tradicional continuar a impor restrições e a controlar o fluxo de capital, Bitcoin permanecerá como um símbolo de independência e soberania financeira.

Thailand Approves Five Year Bitcoin And Crypto Tax BreakThailand has approved a five year tax exemption on capital gains from cryptocurrency trading made through licensed digital asset platforms. The exemption will be in effect from January 1, 2025, through December 31, 2029.
JUST IN:
Thailand’s cabinet approved personal tax waiver on profits from the #Bitcoin and crypto sale over five years. pic.twitter.com/4gWc1gn84j
— Bitcoin Magazine (@BitcoinMagazine) June 17, 2025
Deputy Finance Minister Julapun Amornvivat announced the measure, calling it a move to increase investment, stimulate economic activity, and drive long term growth.
Amornvivat stated, “The Cabinet approved a five-year crypto tax exemption to promote Thailand as a global digital asset hub.”
According to the Ministry of Finance, the policy is designed to strengthen Thailand’s competitiveness in the global digital economy. It targets transparent growth, and aims to increase capital inflow into the Thai market. Officials expect over 1 billion baht in indirect tax revenue to result from the increased economic activity during the exemption period.
Amornvivat went on to say, “The capital gain tax exemption will be for the sale of digital assets made through operators regulated by the Securities and Exchange Commission.”
The tax break applies only to platforms licensed by the Thai SEC. This includes exchanges that meet strict regulatory standards under the government’s digital finance framework. Exchanges without Thai licenses will not benefit from the exemption and continue to face restrictions.
Officials say the new exemption aligns with international standards from the OECD and FATF. The government is also exploring a possible value-added tax (VAT) on digital assets to support fiscal stability.
Furthermore, this isn’t Thailand’s first step toward embracing Bitcoin or crypto.
Thailand approved its first spot Bitcoin ETF in 2024, allowing asset manager ONEAM to launch a fund for institutional investors. The ETF offers regulated exposure to Bitcoin through global funds and reflects growing demand for institutional access to the asset.
Thailand is taking a two sided approach. They support innovation through licensed platforms, while cracking down on unregulated players. With clearer rules and tax breaks, the country is positioning itself as a leader for Bitcoin and crypto growth in Southeast Asia.

2025-06-17 15:19:29A mineração de Bitcoin é um processo crucial para o funcionamento e a segurança da rede. Ela tem um papel importante na validação de transações e na geração de novos bitcoins, garantindo a integridade do sistema baseado em blockchain ou timechain. Esse processo envolve resolver cálculos matemáticos complicados, exigindo grande poder computacional. Além disso, a mineração tem efeitos econômicos, ambientais e tecnológicos que devem ser analisados de forma detalhada.
A mineração de Bitcoin é o procedimento pelo qual novas unidades da moeda são criadas e adicionadas à rede. Ela também é responsável por verificar e registrar transações no blockchain ou timechain. Esse sistema foi criado para ser descentralizado, eliminando a necessidade de uma autoridade central para controlar a emissão ou validar operações.
Os participantes do processo, chamados de mineradores, competem para resolver problemas matemáticos difíceis. Aquele que achar a solução primeiro ganha o direito de adicionar um novo bloco ao blockchain ou timechain e recebe uma recompensa em bitcoins, além das taxas de transação que estão no bloco. Esse mecanismo é chamado de prova de trabalho (Proof of Work - PoW).
O processo de mineração é muito técnico e segue uma série de etapas:
Agrupamento de transações: as transações enviadas pelos usuários são reunidas em um bloco pendente, que aguarda validação.
Resolução de problemas matemáticos: os mineradores devem encontrar um número específico, chamado nonce, que, quando combinado com os dados do bloco, gera um hash criptográfico dentro de um padrão exigido. Esse processo requer tentativa e erro, consumindo alto poder computacional.
Validação do bloco: quando um minerador encontra a solução correta, o bloco é validado e adicionado ao blockchain ou timechain. Todos os nós da rede verificam a autenticidade do bloco antes de aceitá-lo.
Recompensa: o minerador que vencer recebe uma recompensa em bitcoins, além das taxas pagas pelas transações que estão no bloco. Essa recompensa diminui ao longo do tempo em um evento chamado halving, que acontece aproximadamente a cada quatro anos.
A mineração de Bitcoin tem um impacto econômico grande, pois cria oportunidades de renda para pessoas e empresas. Ela também estimula o desenvolvimento de novas tecnologias, como processadores especializados (ASICs) e sistemas de resfriamento modernos.
Além disso, a mineração apoia a inclusão financeira ao manter uma rede descentralizada, permitindo transações rápidas e seguras em nível global. Em áreas com economias instáveis, o Bitcoin oferece uma alternativa viável para preservação de valor e transferências financeiras.
Apesar de seus benefícios econômicos, a mineração de Bitcoin é frequentemente criticada por seu impacto no meio ambiente. O processo de prova de trabalho consome grandes quantidades de eletricidade, especialmente em áreas onde a matriz energética depende de fontes fósseis.
Estima-se que a mineração de Bitcoin consuma tanta energia quanto alguns países inteiros, levantando preocupações sobre sua sustentabilidade. No entanto, há esforços contínuos para reduzir esses impactos, como o uso crescente de fontes de energia renovável e soluções alternativas, como redes baseadas na prova de participação (Proof of Stake - PoS) em outros sistemas descentralizados.
A mineração também enfrenta desafios ligados à escalabilidade e à concentração de poder computacional. Grandes empresas e pools de mineração dominam o setor, o que pode afetar a descentralização da rede.
Outro desafio é a complexidade crescente dos cálculos matemáticos, que exige hardware mais avançado e consome mais energia com o tempo. Para enfrentar esses problemas, pesquisadores estudam soluções que otimizem o uso de recursos e mantenham a rede sustentável por um longo período.
Resumindo, a mineração de Bitcoin é um processo essencial para manter a rede e para a criação de novas unidades da moeda. Ela garante segurança, transparência e descentralização, sustentando o funcionamento do blockchain ou timechain.
No entanto, a mineração também traz desafios, como o alto consumo de energia e a concentração de recursos em grandes pools. Apesar disso, a busca por soluções sustentáveis e inovações tecnológicas indica um futuro promissor, onde o Bitcoin continuará a ter um papel central na economia digital.

2025-06-17 17:33:02Bitcoin tem vindo a desempenhar um papel cada vez mais relevante em protestos e movimentos sociais em todo o mundo. Graças à sua natureza descentralizada, resistente à censura e independente do controlo governamental, Bitcoin tornou-se uma ferramenta valiosa para ativistas, organizações e cidadãos que lutam contra regimes opressivos ou sistemas financeiros restritivos.
Bitcoin como alternativa ao sistema financeiro tradicional
Nos últimos anos, governos e instituições bancárias têm utilizado restrições financeiras como uma forma de repressão política. Contas bancárias congeladas, doações bloqueadas e limitações a transações são algumas das estratégias utilizadas para enfraquecer movimentos sociais e protestos. Bitcoin oferece uma alternativa, permitindo que fundos sejam transferidos e armazenados sem a interferência de bancos ou governos.
Uma das principais vantagens de Bitcoin nestes contextos é a sua resistência à censura. Enquanto contas bancárias podem ser encerradas e serviços de pagamento centralizados podem ser pressionados a bloquear transações, Bitcoin funciona numa rede descentralizada, onde ninguém pode impedir que um utilizador envie ou receba fundos.
Exemplos do uso do Bitcoin em protestos
Hong Kong (2019-2020): Durante os protestos pró-democracia, ativistas enfrentaram restrições financeiras ao tentarem organizar manifestações e campanhas. Muitos recorreram a Bitcoin para evitar o rastreamento do governo chinês e garantir financiamento para as suas ações.
Canadá (2022): O movimento dos camionistas que protestavam contra restrições governamentais viu as suas contas bancárias congeladas. Como alternativa, doações em Bitcoin foram utilizadas para contornar a repressão financeira.
Bielorrússia (2020): Após as eleições presidenciais contestadas, manifestantes usaram Bitcoin para financiar atividades e ajudar aqueles que perderam os seus empregos devido à repressão estatal.
Nigéria (2020): Durante os protestos contra a brutalidade policial, conhecidos como #EndSARS, doações internacionais para os manifestantes foram bloqueadas. Bitcoin tornou-se um dos principais meios de financiamento do movimento.
Desafios do uso do Bitcoin em movimentos sociais
Educação e acessibilidade: Muitos ainda desconhecem como utilizar Bitcoin de forma segura e eficiente. A falta de conhecimento pode dificultar a sua adoção em larga escala.
Segurança digital: Movimentos sociais muitas vezes operam sob vigilância intensa. Se as medidas de segurança adequadas não forem seguidas, os fundos podem ser comprometidos.
Volatilidade: O preço de Bitcoin pode variar significativamente num curto período, o que pode afetar o valor das doações e dos fundos arrecadados.
Resumindo, o Bitcoin tem demonstrado ser uma ferramenta essencial para a resistência contra a censura financeira e a repressão governamental. Ao permitir que movimentos sociais e ativistas financiem as suas causas sem depender de intermediários, Bitcoin fortalece a luta pela liberdade e pela justiça. No entanto, a adoção eficaz da tecnologia exige conhecimento, segurança e adaptação às suas características únicas. À medida que mais pessoas aprendem a utilizar Bitcoin, o seu papel nos protestos e movimentos sociais continuará a crescer, reforçando a importância da soberania financeira na luta por direitos e liberdades.

2025-06-17 05:54:52ปี 1937 — บริษัท Hormel Foods Corporation ในเมืองออสติน รัฐมินนิโซตา สหรัฐฯ ชายคนหนึ่งชื่อ Jay C. Hormel ลูกชายของผู้ก่อตั้งบริษัท มีไอเดียแสนทะเยอทะยานว่า “อยากทำผลิตภัณฑ์จากหมู ที่เก็บได้นาน ไม่ต้องแช่เย็น และไม่แพง”
เพราะตอนนั้น หมูเหลือเยอะ โดยเฉพาะ “หัวไหล่หมู” ที่ขายไม่ออก เพราะมันไม่ใช่ชิ้นเนื้อพรีเมียมที่คนอยากซื้อไปทำอาหาร เจย์เลยทดลองบดเนื้อไหล่หมู เติมเกลือ น้ำตาล สารกันเสีย โซเดียมไนไตรต์ และสิ่งสำคัญสุดคือ เจลาตินจากน้ำต้มกระดูก เพื่อให้เนื้อเกาะตัว ไม่แห้ง และอยู่ได้นานโดยไม่ต้องแช่เย็น
ผลลัพธ์คือ หมูกระป๋อง 340 กรัมในกล่องสี่เหลี่ยม พร้อมเปิดฝาดึงด้วยมือ ไม่ต้องใช้ที่เปิดกระป๋อง ชูความ ราคาถูก เก็บง่าย พกพาสะดวก และไม่ต้องปรุงอะไรเพิ่มเติม ซ่อนความของเหลือเอาไว้เงียบๆ
และเพื่อให้คนจำได้ง่าย บริษัทจัดประกวดตั้งชื่อ และผู้ชนะเสนอคำว่า “Spam” = Spiced Ham (แต่ไม่มีใครรู้จริงๆ ว่าย่อจากอะไรแน่) แค่ “สั้น จัดจ้าน และจำง่าย” ก็พอ
เมื่อเกิดสงครามโลกครั้งที่ 2 ในปี 1939 สหรัฐฯ ยังไม่เข้าสงครามเต็มตัว แต่เริ่มเตรียมเสบียงสนับสนุนพันธมิตร และ Spam กลายเป็นของขวัญจากพระเจ้า เพราะ เก็บได้นานหลายปี ไม่ต้องแช่เย็น น้ำหนักเบา เปิดง่าย ไม่เสียง่ายแม้เจอฝุ่น โคลน หรือไอร้อนจากปืนใหญ่
รัฐบาลสหรัฐฯ เริ่มจัดสั่ง Spam ให้กับกองทัพในสัดส่วนที่มากขึ้นเรื่อยๆ โดยเฉพาะทหารแนวหน้าในยุโรปและแปซิฟิก เช่น ฮาวาย, ฟิลิปปินส์, กวม, และเกาหลี ระหว่างสงคราม Hormel ผลิต Spam มากถึง 15 ล้านกระป๋องต่อสัปดาห์ และส่งออกไปมากกว่า 100 ล้านกระป๋อง ภายในเวลาไม่กี่ปี
Jay C. Hormel ถือว่ามีบทบาททางสังคมและการเมืองอยู่ไม่น้อย โดยเฉพาะช่วงก่อนสงครามโลกครั้งที่ 2
เขาเคยเป็นสมาชิกของ America First Committee ซึ่งเป็นกลุ่มเคลื่อนไหวทางการเมืองที่มีอิทธิพลมากในช่วงก่อนสงครามโลกครั้งที่ 2 โดยกลุ่มนี้มีเป้าหมายคือ “ต่อต้านการที่อเมริกาจะเข้าไปร่วมสงครามในยุโรป” สมาชิกของกลุ่มนี้มีทั้งนักธุรกิจใหญ่ สื่อมวลชน นักวิชาการ รวมถึงชาร์ลส ลินด์เบิร์ก (นักบินชื่อดัง) เรียกได้ว่าเป็นกลุ่มที่มีอิทธิพลเชิงความคิดและการเมืองในช่วงปลายยุค 1930s
แม้ในตอนแรก Hormel จะมีแนวคิดไม่เห็นด้วยกับการเข้าสงคราม แต่พอสงครามเริ่มต้นจริง และสหรัฐฯ ต้องส่งทหารและเสบียงออกไปรบ เขาก็ “ปรับตัวทันที” และกลายเป็นหนึ่งในผู้จัดหาอาหารรายใหญ่ให้กองทัพ โดยเฉพาะ Spam ที่ผลิตส่งเป็นล้านกระป๋องต่อสัปดาห์ ซึ่งแน่นอนว่าไม่มีทางทำได้ถ้าไม่มีความสัมพันธ์และการประสานงานกับภาครัฐโดยตรง
หลังสงครามโลกสิ้นสุดในปี 1945 สิ่งที่รัฐบาลและภาคธุรกิจต้องเจอคือ จะทำยังไงกับโรงงานผลิตอาหารที่เคยทำเพื่อ “เลี้ยงทหารนับล้าน” แต่ตอนนี้ไม่มีสงครามแล้ว? Hormel ไม่ยอมให้ Spam หายไปจากโต๊ะอาหารโลกง่ายๆ แผนการตลาดที่ฉลาดมากของพวกเขาคือ 1. “Sell the nostalgia” ขายความทรงจำ! คนอเมริกันที่เป็นทหารผ่านศึก กลับมาใช้ชีวิตปกติ แต่ก็ยังคุ้นเคยกับ Spam อยู่แล้ว ก็ขายให้พวกเขานั่นแหละ 2. “ผูกกับอาหารเช้า” Hormel ทำสูตร “Spam and eggs” และโฆษณาว่าเป็นอาหารเช้าที่ให้พลังงาน ย่อยง่าย และเหมาะกับทุกครอบครัว 3. เจาะตลาดประเทศที่ได้รับ Spam ระหว่างสงคราม ฟิลิปปินส์, ฮาวาย, ญี่ปุ่น, เกาหลีใต้, อังกฤษ กลายเป็นตลาดหลัก บางประเทศพัฒนาเมนูท้องถิ่นกับ Spam เช่น ฟิลิปปินส์ Spam silog (Spam + ข้าว + ไข่ดาว), เกาหลี 부대찌개 (Budae-jjigae) หรือหม้อไฟทหาร, ญี่ปุ่น Spam onigiri, ฮาวาย Spam musubi (สแปมวางบนข้าว ปิดด้วยสาหร่าย) 4. สร้างแบรนด์ให้รัก Hormel สนับสนุนการจัดงานเทศกาล Spam (เช่น Spam Jam) และทำให้แบรนด์กลายเป็น Pop Culture ของอเมริกา เพื่อโปรโมตแบรนด์ให้เป็นของอเมริกันจ๋า ทั้งน่ารัก ทั้งเท่ ทั้งกินง่าย และกลายเป็นความภูมิใจของชนชั้นกลาง
ระหว่างปี 1937–1946 Spam สร้างชื่อให้ Hormel อย่างถล่มทลาย ถึงขั้นรัฐบาลโซเวียตยังเคยร้องขอให้สหรัฐฯ ส่ง Spam เข้าโซเวียตเพื่อเลี้ยงทหารแนวหน้า โดย นายพล Dwight D. Eisenhower (ต่อมาคือประธานาธิบดีสหรัฐฯ) เคยกล่าวว่า “I ate my share of Spam along with millions of other soldiers. I’ll even confess to a few unkind remarks about it—uttered during the strain of battle... But as former Commander in Chief, I believe I can still see Spam in my dreams.” (ฉันกิน Spam มากพอๆ กับทหารหลายล้านคน แม้จะเคยบ่นบ้าง แต่ในฐานะอดีตแม่ทัพใหญ่...ฉันยังฝันเห็นมันเลย)
Jay C. Hormel ไม่ใช่แค่คนขายหมู แต่เขาเป็นนักวางระบบอุตสาหกรรมขั้นเทพ สามารถยกระดับกิจการท้องถิ่นของพ่อให้กลายเป็นบริษัทอาหารที่ส่งออกระดับโลกได้ เขาเป็น early adopter ของสิ่งที่เรียกว่า vertical integration คือควบคุมทุกขั้นตอน ตั้งแต่ฟาร์ม โรงฆ่าสัตว์ โรงงาน บรรจุภัณฑ์ จนถึงการขนส่งและการตลาด
ในปี 1970s รายการตลกชื่อดังของอังกฤษอย่าง Monty Python’s Flying Circus ได้เอา Spam มาเล่นมุกในตอนหนึ่ง โดยฉากคือร้านอาหารที่ทุกเมนูมี Spam อยู่ในนั้น แล้วลูกค้าพยายามสั่งอาหารโดยไม่เอา Spam แต่ร้านไม่ยอม เพราะ “เมนูเรามี Spam ทุกอย่าง!” จนเสียงลูกค้ากับแม่ค้ากลายเป็นการโต้เถียงอันแสนตลก และมีนักแสดงแต่งเป็นไวกิ้งยืนร้อง “Spam, Spam, Spam, Spam...” ซ้ำๆ อยู่ด้านหลังแบบไม่รู้จบ https://youtu.be/anwy2MPT5RE?si=-68WQeng47lhJENJ
ฉากนั้นกลายเป็นตำนานในโลกตลก และคำว่า “Spam” ก็เริ่มถูกใช้เป็นคำสแลงหมายถึง “ของที่ซ้ำซาก ไร้สาระ รบกวน” ซึ่งต่อมาก็กลายเป็นคำที่เราใช้เรียกอีเมลหรือข้อความขยะนั่นเอง
จะว่าไปแล้ว Spam ถือเป็น “สินค้าที่ครอบงำและเปลี่ยนแปลงอาหารของโลกอีกตัวนึง” อย่างแท้จริง จากเศษหมูไร้คนซื้อ → สินค้าแห่งนวัตกรรมอาหาร → เสบียงสงคราม → อาหารเช้าคลาสสิก → วัฒนธรรมท้องถิ่น → Meme ตลก → และสุดท้ายก็กลายเป็นคำด่าบนอินเทอร์เน็ต
Jay C. Hormel ไม่ได้เป็นนักการเมือง แต่เขาเป็น “นักอุตสาหกรรมที่มีบทบาททางการเมือง” โดยเฉพาะในช่วงเปลี่ยนผ่านของประเทศจาก “ไม่เอาสงคราม” ไปสู่ “ต้องชนะสงคราม”
เขาอาจเริ่มจากแนวคิด “อย่ายุ่งเรื่องคนอื่น” แต่พอเห็นว่าโอกาสมา เขาก็เปลี่ยนโหมดทันที และทำให้ Spam กลายเป็นเสบียงระดับชาติ แบบนี้แหละเฮียถึงบอกว่า “สงครามทำให้คนธรรมดากลายเป็นตำนาน” ...หรือไม่ก็ “สงครามทำให้ธุรกิจธรรมดากลายเป็นธุรกิจผูกขาดที่ไม่มีใครเลิกกินได้อีกเลย”
Spam ไม่ใช่แค่อาหารกระป๋อง แต่เป็นเครื่องมือทางภูมิสงคราม อุตสาหกรรม และการตลาด จากห้องครัวทดลองเล็กๆ ในมินนิโซตา กลายเป็นไอเท็มในสนามรบระดับโลก และสุดท้าย…ก็กลายเป็นทั้ง อาหารในตู้, มุกในมุขตลก, และ คำด่าบนโลกออนไลน์ ทั้งหมดนี้เริ่มต้นจากคำเดียว... "หมูมันเหลือ"

Fold Holdings Secures $250 Million Equity Deal to Expand Bitcoin TreasuryToday, Fold Holdings, Inc. (NASDAQ: FLD), the first publicly traded bitcoin financial services company, has announced a $250 million equity purchase agreement to significantly increase its bitcoin holdings.
JUST IN:
Publicly traded Fold secures $250 million equity facility to buy more #Bitcoin pic.twitter.com/M7E3fzwAsT
— Bitcoin Magazine (@BitcoinMagazine) June 17, 2025
Fold Holdings has the option, but not the obligation, to issue and sell up to $250 million in new common stock. The ability to access the funds is subject to certain conditions, including the requirement that a registration statement covering the resale of the stock be filed with and approved by the Securities and Exchange Commission (SEC).
“The Company is not required to use the Facility and controls the timing and amount of any drawdown on the Facility, subject to certain restrictions under the Facility,” said the press release. “The Company expects to use the net proceeds from the Facility, if any, primarily to acquire additional bitcoin for Fold’s corporate treasury.”
The shares offered under the facility will be issued through a private placement, relying on exemptions from the registration requirements of the Securities Act of 1933 and Regulation D. Fold noted that it “plans to file with the SEC a registration statement relating to the resale of the Common Stock issuable under the Facility.”
“The offers and sales of the Common Stock issuable under the Facility will be made in a private placement in reliance on an exemption from the registration requirements of the Securities Act of 1933,” according to the press release. “The Company cannot draw on the Facility, and the Common Stock may not be sold nor may offers to buy be accepted, prior to the time that the registration statement covering the resale of the Common Stock is declared effective by the SEC.”
On May 19, Fold also announced the launch of its Bitcoin gift card, marking its entry into the $300 billion U.S. retail gift card market. This new product allows consumers to purchase and gift bitcoin through familiar retail channels, with plans to expand to major retailers nationwide throughout the year.
“This gift card gives us distribution directly to millions of Americans who may not be buying Bitcoin because they haven’t downloaded a new app, don’t have a brokerage account, or haven’t seen the ETF,” said the Chairman and CEO of Fold Will Reeves.
“I think there’s a real chance by the end of 2025 that Bitcoin becomes the most popular gift in America because of this card,” stated Reeves.

@ b1ddb4d7:471244e7
2025-06-17 05:02:27This article was originally published on dev.to by satshacker.
Alright, you’ve built a useful and beautiful website, tool or app. However, monetization isn’t a priority and you’d rather keep the project free, ads-free and accessible?
Accepting donations would be an option, but how? A PayPal button? Stripe? Buymeacoffe? Patreon?
All of these services require a bank account and KYC verification, before you can send and receive donations – not very convenient.
If we only could send value over the internet, with just one click and without the need of a bank account…
Oh, hold on, that’s bitcoin. The decentralized protocol to send value across the globe. Money over TCP/IP.
In this article, we’ll learn how anyone can easily add a payment button or donation widget on a website or app.
Let’s get into it.
Introduction
Bitcoin is digital money that you can send and receive without the need for banks. While bitcoin is extremely secure, it’s not very fast. The maximum transactions per second (TPS) the network can handle is about 7. Obviously that’s not useful for daily payments or microtransactions.
If you’d like to dig deeper into how bitcoin works, a great read is “Mastering Bitcoin” by Andreas Antonopoulos.
Bitcoin vs Lightning
If you’d like to receive bitcoin donations “on-chain” all you need is a bitcoin wallet. You simply display your bitcoin address on your site and that’s it. You can receive donations.
It would look something like this; 1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa
Instead of showing the actual bitcoin address, you can also turn it into a QR code.
However, this is not a recommended solution. Using static on-chain addresses has two major downsides. It lowers privacy for you and your donnors and it’s a UTXO disaster because many small incoming transactions could beocme hard to consolidate in the future.
For donations and small transactions, the Lightning Network is the better option. Lightning allows for instant settlement with fees only a fraction of a cent.
Similar to bitcoin, you have the choice between non-custodial and custodial wallets. This means, either you have full control over your money or the wallet provider has.
Option 1: Lightning Address
With the lightning address feature, you an easily receive donations to an email like address.
It looks like this: yourname@wallet.com
Many wallets support lightning addresses and make it easy to create one. Then, you simple add the address to your donation page and you’re ready to receive tips.
You can also add a link link as in lightning:yourname@wallet.com and compatible lightning wallets and browser wallets will detect the address.
Option 2: Lightning Donation Widgets
If you like to take it a step further, you can also create a more enhanced donation checkout flow. Of course you could programm something yourself, there are many open source libraries you can build upon. If you want a simple plug-and-play solution, here are a couple of options:
Name
Type
Registration
SatSale
Self-hosted
No KYC
BTCPay Server
Self-hosted
No KYC
Pay With Flash
Widget
Email
Geyser Fund
Widget

SatSale (GitHub)
Lightweight, self-hosted Bitcoin/Lightning payment processor. No KYC.
Ideal for developers comfortable with server management. Simple to deploy, supports both on-chain and Lightning, and integrates with WooCommerce.
BTCPay Server
Powerful, open-source, self-hosted processor for Bitcoin and Lightning. No KYC.
Supports multiple currencies, advanced features, and full privacy. Requires technical setup and maintenance. Funds go directly to your wallet; great for those seeking full control.
Pay With Flash
Easiest for indie hackers. Add a donation widget with minimal code and no KYC. Payments go directly to your wallet for a 1.5% fee.
Setup Steps:
- Sign up at PayWithFlash.com
- Customize your widget in the dashboard
- Embed the code:
- Test to confirm functionality
Benefits:
- Minimal technical skills required
- Supports one-time or recurring donations
- Direct fund transfer, no intermediaries
Geyser Fund
Crowdfunding platform. Widget-based, connects to your wallet, email registration.Focused on Bitcoin crowdfunding, memberships and donations.
The Giving Block
Hosted, KYC required. Integrates with fiat and crypto, best for nonprofits or larger organizations.
OpenNode
Hosted, KYC required. Accept Bitcoin payments and donations; supports conversion to fiat, suitable for businesses and nonprofits.
Summary
- Fast, low-code setup: Use Pay With Flash or Geyser Fund.
- Privacy and control: Choose SatSale or BTCPay Server (requires technical skills).
- Managed, compliant solutions: The Giving Block or OpenNode.
Choose based on your technical comfort, privacy needs, and project scale.
I hope this article helped you. If you added bitcoin donations, share your link in the comments and I will send you a few satoshis maybe

Ukraine Introduces Bill to Allow Bitcoin in National ReservesUkraine has introduced a bill that would give its central bank the legal right to hold Bitcoin and other assets as part of its national reserves. The draft law, submitted to the Verkhovna Rada on June 10, 2025, proposes updates to existing legislation to include “virtual assets” in the foreign exchange and gold reserves of the National Bank of Ukraine (NBU).
NEW: Ukraine introduces bill for Bitcoin Reserve in Parliament
pic.twitter.com/bYIiCNF13D
— Bitcoin Magazine (@BitcoinMagazine) June 17, 2025
This doesn’t mean Ukraine is officially adding Bitcoin to its balance sheet just yet, but it would give the central bank the green light to do so in the future.
One of the bill’s co-sponsors, Member of Parliament Yaroslav Zhelezniak, emphasized that the legislation is about granting permission, not making it a requirement. “Whether and to what extent they actually do so,” he said, “is up to the institution itself.”
Zhelezniak recently discussed with Binance’s regional head Kyrylo Khomiakov, that he believes Bitcoin could help Ukraine strengthen its economic position and contribute to long term digital innovation.
The timing of the bill is vital as Ukraine has been under enormous financial pressure since Russia’s invasion in 2022. Inflation remains high, the hryvnia has lost significant value, and the country is heavily reliant on international aid and loans. The NBU has managed to hold roughly $44.5 billion in reserves, mostly in U.S. dollars and government securities, but its room to maneuver is limited.
Back in 2022, the Ukrainian government was actively raising donations for the war effort through Bitcoin. They had an official wallet set up for donations, and their politicians were publicly tweeting out the addresses asking for support. On the first day alone, Ukraine’s official Bitcoin wallet raised over $3.5 million. By leaning into Bitcoin during their time of crisis, the government showed their belief and commitment in it, and this new bill shows that that commitment has not faded.

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

2025-06-17 17:31:08Milhões de pessoas em todo o mundo ainda não têm acesso a serviços bancários básicos, seja por falta de infraestrutura, requisitos burocráticos ou instabilidade económica nos seus países. Bitcoin surge como uma solução inovadora para este problema, permitindo que qualquer pessoa com acesso à internet tenha controlo sobre o seu dinheiro, sem depender de bancos ou governos. Ao oferecer um sistema financeiro aberto e acessível, Bitcoin torna-se uma ferramenta poderosa para a inclusão financeira global.
O problema da exclusão financeira
Em muitos países em desenvolvimento, grande parte da população não possui conta bancária. Isto pode acontecer por diversas razões, como:
Falta de acesso a bancos: Muitas comunidades, especialmente em áreas rurais, não têm instituições financeiras próximas.
Exigências burocráticas: Alguns bancos exigem documentação específica ou um histórico de crédito que muitas pessoas não conseguem fornecer.
Custos elevados: As taxas bancárias podem ser proibitivas para quem ganha pouco dinheiro.
Instabilidade económica e política: Em países com alta inflação ou governos instáveis, os bancos podem não ser uma opção segura para guardar dinheiro.
Estas dificuldades deixam milhões de pessoas à margem do sistema financeiro, impossibilitadas de poupar, investir ou realizar transações de forma eficiente.
Bitcoin como alternativa
Bitcoin resolve muitos dos problemas da exclusão financeira ao oferecer um sistema acessível e descentralizado. Com Bitcoin, qualquer pessoa com um telemóvel e acesso à internet pode armazenar e transferir dinheiro sem necessidade de um banco. Entre as principais vantagens estão:
Acessibilidade global: Bitcoin pode ser usado em qualquer lugar do mundo, independentemente da localização do utilizador.
Sem necessidade de intermediários: Diferente dos bancos, que impõem taxas e regras, Bitcoin permite transações diretas entre pessoas.
Baixo custo para transferências internacionais: Enviar dinheiro para outro país pode ser caro e demorado com os métodos tradicionais, enquanto Bitcoin oferece uma alternativa mais rápida e acessível.
Proteção contra a inflação: Em países com moedas instáveis, Bitcoin pode ser usado como reserva de valor, protegendo o poder de compra da população.
Casos de uso na inclusão financeira
Bitcoin já tem sido utilizado para promover a inclusão financeira em diversas partes do mundo. Alguns exemplos incluem:
África e América Latina: Em países como Nigéria, Venezuela e Argentina, onde a inflação é elevada e o acesso a dólares é limitado, muitas pessoas usam Bitcoin para preservar o seu dinheiro e realizar transações internacionais.
Remessas internacionais: Trabalhadores que enviam dinheiro para as suas famílias no estrangeiro evitam as elevadas taxas das empresas de transferências tradicionais ao utilizarem Bitcoin.
Microeconomia digital: Pequenos comerciantes e freelancers que não têm acesso a contas bancárias podem receber pagamentos em Bitcoin de forma direta e segura.
Desafios da inclusão financeira com Bitcoin
Apesar das suas vantagens, a adoção de Bitcoin como ferramenta de inclusão financeira ainda enfrenta alguns desafios, tais como:
Acesso à internet: Muitas regiões pobres ainda não têm uma infraestrutura digital adequada.
Educação financeira: Para que mais pessoas utilizem Bitcoin, é necessário maior conhecimento sobre a tecnologia e as melhores práticas de segurança.
Volatilidade do preço: As oscilações de valor podem dificultar o uso de Bitcoin no dia a dia, especialmente em países onde as pessoas vivem com rendimentos instáveis.
Resumindo, o Bitcoin oferece uma solução viável para milhões de pessoas excluídas do sistema financeiro tradicional. Ao proporcionar acesso global, transações baratas e segurança contra a inflação, torna-se um instrumento poderoso para promover a inclusão financeira. No entanto, para que o seu potencial seja totalmente aproveitado, é essencial investir na educação digital e expandir a infraestrutura tecnológica, permitindo que mais pessoas tenham autonomia financeira através de Bitcoin.

"Privacy is necessary for an open society in the electronic age. Privacy is not secrecy. A private matter is something one doesn't want the whole world to know, but a secret matter is something one doesn't want anybody to know. Privacy is the power to selectively reveal oneself to the world." - Eric Hughes, A Cypherpunk's Manifesto, 1993
Privacy is essential to freedom. Without privacy, individuals are unable to make choices free from surveillance and control. Lack of privacy leads to loss of autonomy. When individuals are constantly monitored it limits our ability to express ourselves and take risks. Any decisions we make can result in negative repercussions from those who surveil us. Without the freedom to make choices, individuals cannot truly be free.
Freedom is essential to acquiring and preserving wealth. When individuals are not free to make choices, restrictions and limitations prevent us from economic opportunities. If we are somehow able to acquire wealth in such an environment, lack of freedom can result in direct asset seizure by governments or other malicious entities. At scale, when freedom is compromised, it leads to widespread economic stagnation and poverty. Protecting freedom is essential to economic prosperity.
The connection between privacy, freedom, and wealth is critical. Without privacy, individuals lose the freedom to make choices free from surveillance and control. While lack of freedom prevents individuals from pursuing economic opportunities and makes wealth preservation nearly impossible. No Privacy? No Freedom. No Freedom? No Wealth.
Rights are not granted. They are taken and defended. Rights are often misunderstood as permission to do something by those holding power. However, if someone can give you something, they can inherently take it from you at will. People throughout history have necessarily fought for basic rights, including privacy and freedom. These rights were not given by those in power, but rather demanded and won through struggle. Even after these rights are won, they must be continually defended to ensure that they are not taken away. Rights are not granted - they are earned through struggle and defended through sacrifice.

BBVA Tells Wealthy Clients to Invest Up to 7% in BitcoinSpanish bank BBVA is now advising its wealthy clients to invest up to 7% of their portfolios in crypto and Bitcoin, showing how traditional banks are starting to see the potential of Bitcoin.
JUST IN:
Spain's second largest bank BBVA is telling wealthy clients to invest in Bitcoin — Reuters pic.twitter.com/i2Pqg85uSk
— Bitcoin Magazine (@BitcoinMagazine) June 17, 2025
“With private customers, since September last year, we started advising on Bitcoin,” said Philippe Meyer, head of digital & blockchain solutions at BBVA Switzerland, during the DigiAssets conference in London. “The riskier profile, we allow up to 7% of portfolios in crypto.”
The bank’s private wealth division is currently recommending clients allocate 3% to 7% of their portfolio to Bitcoin and crypto, depending on their individual appetite. While many private banks have offered to execute Bitcoin or crypto trades upon request, it remains rare for a global financial institution to formally advise clients to buy. BBVA is currently recommending allocations specifically in Bitcoin.
Meyer emphasized that even a modest allocation to Bitcoin can have a meaningful impact on portfolio returns, “If you look at a balanced portfolio, if you introduce 3%, you already boost the performance,” he said. “At 3%, you are not taking a huge risk.”
BBVA began executing Bitcoin purchases for its clients in 2021, but Meyer said this is the first time it is formally advising allocations. In June 2021, the bank launched Bitcoin trading and custody services through its Swiss subsidiary for private clients. “With this innovative offer, BBVA positions itself as a benchmark institution in the adoption of blockchain technology,” said BBVA Switzerland CEO Alfonso Gómez at the time.
BREAKING: Spain's BBVA is opening #Bitcoin trading and custody to all private banking clients in Switzerland. pic.twitter.com/2ppfs34g6F
— Bitcoin Magazine (@BitcoinMagazine) June 18, 2021
BBVA’s interest in digital currency goes back even further. As early as 2015, the bank made it clear that it viewed Bitcoin and blockchain technology as more than just a passing trend. In a statement that now seems increasingly prescient, BBVA said “institutions that understand Bitcoin and digital currencies will lead the new monetary system,” highlighting its belief that early adopters would gain a strategic advantage.
This early support set BBVA apart from many of its peers, as few major banks were willing to publicly engage with Bitcoin at the time.
What began as interest in blockchain technology has turned into direct investment guidance, now culminating in BBVA formally advising wealthy clients to allocate up to 7% of their portfolios into Bitcoin, a clear sign the bank sees it as a long term part of its future.

2025-06-17 17:01:50The banking giant is exploring an expansion of its blockchain services, focusing on digital payments and currencies.
JPMorgan Chase has filed a new trademark application for the name “JPMD.” The filing was submitted on June 15 to the United States Patent and Trademark Office (USPTO).
The application, filed by JPMorgan Chase Bank, N.A., covers a broad range of services related to digital assets and blockchain technology. These include the issuance of digital currencies, electronic payment processing, and financial custody services — all of which suggest a possible new stablecoin initiative for JPMorgan.
Experience with JPM Coin
This move wouldn’t be JPMorgan’s first foray into blockchain-based finance. The bank already operates JPM Coin, a dollar-pegged stablecoin used to enable instant transactions between institutional clients. The token runs on Quorum, a private blockchain network developed in-house by JPMorgan and based on Ethereum’s technology.
The registration of the JPMD trademark comes as JPMorgan and other major U.S. banks are considering a collaborative stablecoin project through their jointly owned entities: Early Warning Services and The Clearing House.
Similarly, corporations like Walmart and Amazon are mulling the creation of their own stablecoins.

We are nearly at the point that you can recommend a cross platform app that users can install and easily onboard without additional guides or resources.
As companies continue to build walls around their centralized platforms nostr posts will be the easiest to cross reference and verify - as companies continue to censor their users nostr is the best censorship resistant alternative - gradually then suddenly nostr will become the standard. 🫡

2025-06-17 21:01:43Trump Media & Technology Group is targeting the digital asset market by registering a Bitcoin and Ethereum exchange-traded fund (ETF) with NYSE Arca.
On June 16, Truth Social — a company controlled by Trump Media & Technology Group — officially submitted documentation for a Bitcoin and Ethereum-based Exchange Traded Fund (ETF) to the U.S. Securities and Exchange Commission (SEC).
NEW: Trump's Truth Social has filed for a dual Bitcoin & Ethereum ETF. pic.twitter.com/a5iZtrtUyk
— James Seyffart (@JSeyff) June 16, 2025
This initiative would allow the social media platform to diversify its operations by entering the digital asset sector through these financial products.
The filing proposes a trust structure that would directly hold bitcoin and ether, with 75% of the fund’s assets invested in bitcoin and 25% in ether.
The Truth Social Bitcoin and Ethereum ETF will have Yorkville America Digital as the fund’s sponsor, while custody of the digital assets will be entrusted to the Crypto.com exchange.
The choice of NYSE Arca as the listing venue for the fund is no coincidence: this market already hosts several cryptocurrency-linked ETFs and offers the necessary technological infrastructure to manage these financial instruments.
Trump Media & Technology Group’s move aligns with a broader trend in which public companies are increasingly integrating Bitcoin and other digital assets into their corporate treasuries.
Devin Nunes, CEO of Trump Media & Technology Group, stated:
“Trump Media’s vision is to aggressively enhance our offerings and capabilities, which includes holding bitcoin in our corporate treasury.”
The final approval of the Truth Social Bitcoin and Ethereum ETF will depend on the outcome of the regulatory review process at the SEC, which must assess the product’s compliance with current regulations on exchange-traded funds and cryptocurrency investments.

2025-06-17 17:01:31Desde a sua criação, Bitcoin tem sido alvo de debates sobre a sua utilização em atividades ilícitas. muitos críticos afirmam que Bitcoin facilita crimes como lavagem de dinheiro e financiamento de atividades ilegais, devido à sua natureza descentralizada e à possibilidade de realizar transações sem intermediários. no entanto, a realidade é mais complexa e muitas dessas alegações são exageradas ou baseadas em mitos. na verdade, a maioria das transações com Bitcoin são legítimas e até mais rastreáveis do que muitos imaginam.
O mito: Bitcoin é a principal moeda para criminosos
Um dos maiores mitos sobre Bitcoin é a ideia de que ele é amplamente utilizado por criminosos devido ao seu suposto anonimato. este argumento tornou-se popular principalmente devido a casos como o da Silk Road, um mercado negro online desmantelado pelas autoridades em 2013, onde Bitcoin era usado para transações ilegais. no entanto, os dados mais recentes mostram que apenas uma pequena fração das transações em Bitcoin está relacionada com atividades ilícitas.
Além disso, ao contrário do dinheiro em espécie, que é quase impossível de rastrear, todas as transações de Bitcoin são registadas publicamente na blockchain ou timechain. isto significa que qualquer pagamento feito com Bitcoin pode ser analisado e seguido, tornando mais difícil esconder transações suspeitas a longo prazo.
A realidade: Bitcoin é transparente e rastreável
Ao contrário do que muitos pensam, Bitcoin não é completamente anónimo, mas sim pseudónimo. todas as transações ficam registadas na blockchain ou timechain, permitindo que autoridades e analistas de dados consigam seguir os fluxos de dinheiro com precisão. várias empresas especializadas em análise forense de blockchain ou timechain já ajudaram a identificar e desmantelar redes criminosas que tentavam utilizar Bitcoin para fins ilícitos.
Governos e autoridades, como o FBI e a Europol, têm utilizado esta característica para combater crimes financeiros. na prática, criminosos que tentam usar Bitcoin acabam frequentemente por ser apanhados devido à transparência do sistema. por isso, a ideia de que Bitcoin é um refúgio seguro para criminosos não corresponde à realidade.
O uso ilícito de moedas fiduciárias é muito maior
Se compararmos Bitcoin com as moedas fiduciárias tradicionais, como o euro ou o dólar, percebemos que estas são muito mais utilizadas para atividades ilícitas. segundo relatórios de organizações internacionais, a lavagem de dinheiro e o financiamento de crimes organizados ocorrem predominantemente através de bancos, empresas fictícias e dinheiro em espécie.
Por exemplo, em escândalos financeiros globais, como o Panama Papers e o caso do banco HSBC envolvido em lavagem de dinheiro para cartéis, os meios tradicionais foram os preferidos para esconder fortunas ilegais. apesar disso, Bitcoin continua a ser injustamente associado ao crime, enquanto os verdadeiros mecanismos de financiamento ilícito continuam a operar dentro do sistema financeiro convencional.
Resumindo, o mito de que Bitcoin é um meio privilegiado para atividades ilícitas tem sido amplamente desmentido por dados e investigações. apesar de alguns criminosos terem tentado usá-lo no passado, a realidade é que Bitcoin é um sistema financeiro mais transparente e rastreável do que o dinheiro tradicional. a grande maioria das suas transações é legítima e, à medida que a adoção cresce, Bitcoin continua a provar o seu valor como um meio seguro e descentralizado para transações financeiras.

2025-06-16 17:02:09The former seems to have found solid product market fit. Expect significant volume, adoption, and usage going forward.
The latter's future remains to be seen. Dependence on Tor, which has had massive reliability issues, and lack of strong privacy guarantees put it at risk.
— ODELL (@ODELL) October 27, 2022
The Basics
- Lightning is a protocol that enables cheap and fast native bitcoin transactions.
- At the core of the protocol is the ability for bitcoin users to create a payment channel with another user.
- These payment channels enable users to make many bitcoin transactions between each other with only two on-chain bitcoin transactions: the channel open transaction and the channel close transaction.
- Essentially lightning is a protocol for interoperable batched bitcoin transactions.
- It is expected that on chain bitcoin transaction fees will increase with adoption and the ability to easily batch transactions will save users significant money.
- As these lightning transactions are processed, liquidity flows from one side of a channel to the other side, on chain transactions are signed by both parties but not broadcasted to update this balance.
- Lightning is designed to be trust minimized, either party in a payment channel can close the channel at any time and their bitcoin will be settled on chain without trusting the other party.
There is no 'Lightning Network'
- Many people refer to the aggregate of all lightning channels as 'The Lightning Network' but this is a false premise.
- There are many lightning channels between many different users and funds can flow across interconnected channels as long as there is a route through peers.
- If a lightning transaction requires multiple hops it will flow through multiple interconnected channels, adjusting the balance of all channels along the route, and paying lightning transaction fees that are set by each node on the route.
Example: You have a channel with Bob. Bob has a channel with Charlie. You can pay Charlie through your channel with Bob and Bob's channel with User C.
- As a result, it is not guaranteed that every lightning user can pay every other lightning user, they must have a route of interconnected channels between sender and receiver.
Lightning in Practice
- Lightning has already found product market fit and usage as an interconnected payment protocol between large professional custodians.
- They are able to easily manage channels and liquidity between each other without trust using this interoperable protocol.
- Lightning payments between large custodians are fast and easy. End users do not have to run their own node or manage their channels and liquidity. These payments rarely fail due to professional management of custodial nodes.
- The tradeoff is one inherent to custodians and other trusted third parties. Custodial wallets can steal funds and compromise user privacy.
Sovereign Lightning
- Trusted third parties are security holes.
- Users must run their own node and manage their own channels in order to use lightning without trusting a third party. This remains the single largest friction point for sovereign lightning usage: the mental burden of actively running a lightning node and associated liquidity management.
- Bitcoin development prioritizes node accessibility so cost to self host your own node is low but if a node is run at home or office, Tor or a VPN is recommended to mask your IP address: otherwise it is visible to the entire network and represents a privacy risk.
- This privacy risk is heightened due to the potential for certain governments to go after sovereign lightning users and compel them to shutdown their nodes. If their IP Address is exposed they are easier to target.
- Fortunately the tools to run and manage nodes continue to get easier but it is important to understand that this will always be a friction point when compared to custodial services.
The Potential Fracture of Lightning
- Any lightning user can choose which users are allowed to open channels with them.
- One potential is that professional custodians only peer with other professional custodians.
- We already see nodes like those run by CashApp only have channels open with other regulated counterparties. This could be due to performance goals, liability reduction, or regulatory pressure.
- Fortunately some of their peers are connected to non-regulated parties so payments to and from sovereign lightning users are still successfully processed by CashApp but this may not always be the case going forward.
Summary
- Many people refer to the aggregate of all lightning channels as 'The Lightning Network' but this is a false premise. There is no singular 'Lightning Network' but rather many payment channels between distinct peers, some connected with each other and some not.
- Lightning as an interoperable payment protocol between professional custodians seems to have found solid product market fit. Expect significant volume, adoption, and usage going forward.
- Lightning as a robust sovereign payment protocol has yet to be battle tested. Heavy reliance on Tor, which has had massive reliability issues, the friction of active liquidity management, significant on chain fee burden for small amounts, interactivity constraints on mobile, and lack of strong privacy guarantees put it at risk.
If you have never used lightning before, use this guide to get started on your phone.

2025-06-17 17:47:48O protocolo Matrix é um sistema de comunicação descentralizado de código aberto que fornece uma plataforma para mensageiros descentralizados. O Element foi lançado em 2014 como uma implementação do protocolo Matrix, originalmente conhecido como Riot.im , A ideia do Element nasceu quando Matthew Hodgson e Amandine Le Pape, dois desenvolvedores de software, decidiram criar uma plataforma de comunicação aberta e segura, que permitisse aos usuários terem total controle sobre suas informações. Eles acreditavam que a internet deveria ser um lugar onde as pessoas pudessem se comunicar livremente, sem se preocupar com a privacidade de suas informações.
O Element é um aplicativo de chat gratuito e de código aberto disponível em várias plataformas, incluindo desktop, web e aplicativos móveis. Ele oferece criptografia de ponta a ponta, o que significa que as mensagens são protegidas e só podem ser lidas pelo remetente e pelo destinatário. Além disso, o Element é descentralizado, o que significa que ele não é controlado por uma única entidade, mas sim por uma rede global de servidores.
O Element é amplamente utilizado por indivíduos e empresas que desejam ter uma comunicação segura e privada. É frequentemente usado por equipes de projetos, organizações sem fins lucrativos e grupos ativistas que precisam compartilhar informações confidenciais e se comunicar de forma segura. O Element também é conhecido por seu recurso de salas públicas, que permite que os usuários se juntem a grupos de discussão sobre vários tópicos de interesse.
Uma das principais vantagens do Element é sua arquitetura descentralizada. Ao contrário das plataformas de mensagens convencionais que centralizam os dados em seus próprios servidores, o Element utiliza uma rede descentralizada, distribuindo as informações em diversos servidores espalhados pelo mundo. Isso significa que os dados dos usuários são menos suscetíveis a ataques cibernéticos e invasões, já que não são centralizados em um único ponto vulnerável.
Para usar o Element, normalmente os usuários precisam se registrar em um servidor Matrix. Existem várias opções disponíveis, incluindo servidores públicos e privados. No entanto, outra opção é criar um servidor próprio para usar o Element.
O Element também utiliza criptografia de ponta a ponta para proteger as mensagens e arquivos trocados entre os usuários. Isso significa que apenas o remetente e o destinatário das mensagens podem ler o conteúdo, garantindo que as informações permaneçam seguras e privadas.
Outra vantagem do Element é sua ampla variedade de recursos, incluindo videochamadas criptografadas, compartilhamento de tela e integração com outros serviços, como calendários e aplicativos de produtividade. Isso torna o Element uma plataforma completa de comunicação e colaboração, adequada para uso pessoal e empresarial.
O Element também é fácil de usar e possui uma interface intuitiva e personalizável. Os usuários podem personalizar a aparência do aplicativo e acessar diferentes configurações e recursos com apenas alguns cliques.

2025-06-17 16:31:03O Bitcoin tem revolucionado a forma como as pessoas realizam transações financeiras em todo o mundo. Sendo uma moeda digital descentralizada, oferece novas oportunidades para pagamentos no comércio eletrónico e transferências internacionais de dinheiro. A sua rapidez, segurança e baixos custos tornam-no uma alternativa eficiente aos métodos tradicionais, eliminando intermediários e facilitando transações globais.
Bitcoin no comércio eletrónico
O comércio eletrónico tem crescido exponencialmente, e o Bitcoin surge como uma solução inovadora para pagamentos online. Grandes retalhistas e pequenas empresas estão a começar a aceitar Bitcoin como forma de pagamento, oferecendo benefícios tanto para os comerciantes como para os consumidores.
Vantagens do Bitcoin para o comércio eletrónico:
Baixas taxas de transação: ao contrário dos cartões de crédito e plataformas de pagamento que cobram taxas elevadas, as transações em Bitcoin apresentam, geralmente, custos mais reduzidos. Isto beneficia os comerciantes, que podem diminuir despesas e oferecer preços mais competitivos aos clientes.
Eliminação de chargebacks: no sistema tradicional, os chargebacks (reembolsos forçados pelos bancos ou operadoras de cartão) representam uma preocupação para os lojistas. Como as transações em Bitcoin são irreversíveis, os comerciantes evitam fraudes e disputas.
Acesso global: qualquer pessoa com acesso à Internet pode pagar com Bitcoin, independentemente da sua localização. Isto permite às empresas expandirem o seu mercado internacionalmente, sem depender de bancos ou sistemas de pagamento locais.
Privacidade e segurança: as transações em Bitcoin protegem a identidade do utilizador, oferecendo maior privacidade em comparação com pagamentos através de cartão de crédito ou transferências bancárias. Além disso, como não há necessidade de partilhar dados pessoais, o risco de roubo de informações é reduzido.
Desafios do Uso do Bitcoin no Comércio Eletrónico:
Volatilidade: o preço do Bitcoin pode oscilar rapidamente, o que dificulta a fixação de preços para produtos e serviços. No entanto, alguns comerciantes utilizam serviços de pagamento que convertem automaticamente Bitcoin em moeda fiduciária, minimizando esse risco.
Adoção limitada: apesar do crescimento, a aceitação do Bitcoin ainda não é universal. Muitas lojas e plataformas populares ainda não o adotaram, o que pode dificultar a sua utilização em compras diárias.
Tempo de confirmação: embora o Bitcoin seja mais rápido do que as transferências bancárias tradicionais, o tempo de confirmação pode variar consoante a taxa de rede paga. Algumas soluções, como a Lightning Network, estão a ser desenvolvidas para tornar os pagamentos instantâneos.
Bitcoin na remessa de dinheiro
O envio de dinheiro para o estrangeiro sempre foi um processo burocrático, dispendioso e demorado. Serviços tradicionais, como os bancos e empresas de transferência de dinheiro, cobram taxas elevadas e podem demorar dias a concluir uma transação. O Bitcoin, por outro lado, oferece uma alternativa eficiente para remessas globais, permitindo que qualquer pessoa envie e receba dinheiro de forma rápida e económica.
Benefícios do Bitcoin para remessas:
Custos reduzidos: enquanto os bancos e empresas como a Western Union cobram elevadas taxas para transferências internacionais, o Bitcoin permite o envio de dinheiro com custos mínimos, independentemente do montante ou do destino.
Velocidade nas transações: as transferências bancárias internacionais podem demorar vários dias a serem concluídas, especialmente em países com uma infraestrutura financeira limitada. Com o Bitcoin, o dinheiro pode ser enviado para qualquer parte do mundo em poucos minutos ou horas.
Acessibilidade global: em regiões onde o sistema bancário é restrito ou ineficiente, o Bitcoin possibilita que as pessoas recebam dinheiro sem depender de bancos. Isto é particularmente útil em países em desenvolvimento, onde as remessas internacionais são uma fonte essencial de rendimento.
Independência de intermediários: o Bitcoin opera de forma descentralizada, sem necessidade de recorrer a bancos ou empresas de transferência. Isto significa que as pessoas podem enviar dinheiro diretamente para amigos e familiares sem intermediários.
Desafios das remessas com Bitcoin:
Conversão para moeda local: apesar de o Bitcoin poder ser recebido instantaneamente, muitas pessoas ainda precisam de convertê-lo em moeda local para o utilizar. Isso pode envolver custos adicionais e depender da disponibilidade de serviços de câmbio.
Adoção e conhecimento: nem todos compreendem o funcionamento do Bitcoin, o que pode dificultar a sua adoção generalizada para remessas. No entanto, a crescente educação financeira sobre o tema pode ajudar a ultrapassar essa barreira.
Regulamentação e restrições: alguns governos impõem restrições ao uso do Bitcoin, tornando as remessas mais complicadas. A evolução das regulamentações pode afetar a facilidade de uso em determinados países.
Resumindo, o Bitcoin está a transformar o comércio eletrónico e as remessas de dinheiro em todo o mundo. A sua capacidade de eliminar intermediários, reduzir custos e oferecer pagamentos rápidos e seguros torna-o uma alternativa viável aos sistemas financeiros tradicionais.
No comércio eletrónico, proporciona benefícios para lojistas e consumidores, reduzindo taxas e melhorando a privacidade. No setor das remessas, facilita a transferência de dinheiro para qualquer parte do mundo, especialmente para aqueles que vivem em países com sistemas bancários pouco eficientes.
Apesar dos desafios, a adoção do Bitcoin continua a crescer, impulsionada por soluções inovadoras e pelo reconhecimento do seu potencial como meio de pagamento global. À medida que mais empresas e indivíduos aderirem a esta tecnologia, a sua presença no comércio eletrónico e nas remessas internacionais será cada vez mais relevante.

2025-06-17 20:08:48La lingvo kaj ĝia potenco
La nuna lingvo de diplomatio ne devas esti la lingvo de agresema predanto kiel Usono de Usono nek iu ajn alia neŭtrala nacio.
Ĝis hodiaŭ ne estas neŭtralaj nacioj en la planedo kaj tial ne unu sola denaska lingvo ni ideala por diplomatio.
Esperanto estas la plej bona disponebla eblo, moderna kaj riĉa.
Batalu reen por unueco kaj libereco.
Kiel?
Facila, rigardu, kiel ili dividas vin
*1. Per Lingvo:*
Faru al Esperanto vian universalan lingvon, ne donu potencon al la lingvo de unu nacio, kiu donas potencon al tiu nacio kaj al iliaj aliancanoj kaj dividas vin.
*2. De Religio:*
Foriru de iu ajn religia ekstremisma linio kaj laboru por unuigi ilin ĉiujn en unu, labori forte pri ĝi, ĉi tio prenos almenaŭ du generaciojn kaj ĝi komenciĝas per edukado kaj jura reformo forigante la rajton al ĉiuj religiaj organizoj, ili ne devas ekzisti, la fido ne bezonas kompanion senpage kun amasaj financoj krom se ĝi celas manipuli kaj kontroli, malfermi viajn okulojn.
*3 -a per tero:*
Tio daŭros vin pli kaj estas la lasta paŝo, sed post kiam vi sukcesos solvi la unuajn du, vi povas komenci la malrapidan procezon de homa reunuiĝo forigante limojn kaj krei teran nacion.
Kiom da tempo ĝi daŭros?
Nekonata, vi estas tiel juna, eble malmultaj jarcentoj, sed la semoj estas tie, nutras ilin!

Flash Releases Free Bitcoin Invoicing Tool with No Fees, KYC, or CustodyFlash, a Bitcoin payment platform, just announced it has launched Flash Invoicing, a completely free, non-custodial, and KYC-free Bitcoin invoicing tool. Designed for freelancers, the platform allows users to send professional invoices without platform fees, identity checks, or third party custody.
According to Deel, a crypto payments company for freelancers, Bitcoin is the most used cryptocurrency in the world for payments. Despite this growth, many freelancers continue to use basic methods such as pasting Bitcoin addresses into PDFs or emails. Some rely on custodial platforms that deduct fees or require identity verification, which can affect both earnings and data privacy.
“We’ve seen too many people paste BTC addresses into documents and call it invoicing,” said the CEO of Flash Pierre Corbin. “It’s messy. It’s risky. And it’s time for something better.”
Flash Invoicing Features:
- 0% platform fees: no subscriptions or commission
- Non-custodial: Bitcoin goes straight to the user’s wallet
- No KYC: users maintain full privacy
- Professional output: branded PDFs and secure payment links
- Integrated dashboard: manage payments, clients, and revenue
- Works with Flash ecosystem: including Stores, Donations, Paywalls, and POS
Many Bitcoin invoicing tools charge a percentage per transaction or require a subscription. As a result, freelancers often lose part of their income simply to issue an invoice and receive payment. Flash is aiming to solve this issue.
“Freelancers work hard enough. The last thing they need is a platform skimming off their earnings,” said Corbin. “That’s why we dropped our fee from 1.5% to 0% — and launched the first invoicing tool that’s truly free, without compromising on privacy or control.”
Flash Invoicing allows users to accept Bitcoin payments without relinquishing control, privacy, or revenue. It is integrated with the broader Flash suite, enabling users to manage invoicing alongside features such as setting up stores, receiving donations, or gating premium content.
“As a freelancer myself, I love using the Flash invoicing feature,” stated a freelancer & Flash user. ”It keeps all my clients in one place, allows me to easily edit invoices and track payments. Much more professional than sending a lightning address in the footer of a PDF invoice.”

2025-06-17 20:03:08Key Takeaways
Mel Mattison presents a bold, contrarian outlook on today’s economy, arguing that what many view as a precarious bubble is actually the beginning of a long-term structural bull market that could run through 2036. He believes the U.S. economy is far stronger than the headlines suggest, supported by robust job growth, strong consumer balance sheets, and demographic tailwinds. Rather than popping, the current asset bubble is set to expand, driven by retiring baby boomers reducing labor inflation, AI-fueled productivity gains, and massive fiscal stimulus disguised as interest expense. He views Bitcoin as uniquely positioned to thrive in both inflationary and deflationary environments, unlike fiat currency, and sees AI’s high energy demands as a healthy bottleneck that will slow its rollout and allow society to adjust. According to Mattison, the U.S. is entering an era of permanent stimulus and rising productivity, with politics largely irrelevant to the macro trajectory, whether under populist left or populist right, the fiscal and demographic forces shaping the next decade are already locked in.
Best Quotes
“Bitcoin works in an inflationary world and it works in a deflationary world.”
“People are going to look back at 110,000 Bitcoin just like they looked back at 30,000 and say, ‘Man, I should’ve been buying.’”
“Interest expense is fiscal stimulus. There’s no difference between a COVID check and 4.5% on a 3-month bill going into a retiree’s money market account.”
“AI will be massive, but its energy demands are the bottleneck that will save us from an unmanageable shock.”
“This isn’t the 1970s. The U.S. is the largest oil producer in the world, and the demographic structure has flipped.”
“We are in the early stages of a seismic change, think Agricultural Revolution or Industrial Revolution level.”
Conclusion
This episode offers a compellingly optimistic view of the next decade, with Mel Mattison arguing that we’re entering the early stages of a historic bull market driven by demographic shifts, fiscal transformation, and exponential technologies like AI. Rather than collapse, he sees structural strength and enduring growth, positioning Bitcoin as a core asset in this new paradigm, resilient in both inflationary and deflationary cycles. Mattison urges a focus on long-term fundamentals over short-term noise, framing Bitcoin, demographics, and AI as the key forces reshaping the global economic order.

(00:00) the 1971 Nixon shock where he took the US off the gold standard he also put on 10% sweeping across the board tariffs he announced that they were going to do spending cuts something like a Doge this is 55 years ago it's like the exact same things the demographics the oil differences between the 70s and now they're going to allow this situation to work out a lot more like the 80s we had between 1985 and 1996 360% S&P growth the days of 2000 something gold are probably over with Bitcoin you know I've been thinking this month we've got an AI
(00:31) super cycle boom going on it it just all speaks to extreme bullishness but we've got a lot more to go gold and Bitcoin I think actually in geopolitical uncertainties are are only going to do better mel I'm not going to lie I've been pretty disconnected for the last 3 weeks so I'm very excited we're having this conversation cuz I have a feeling it's going to help me catapult back into the present day get caught up with everything that's been going on we had the conference in Vegas a few weeks ago now at this point I had a cross country move between now and then and I had a wedding in Chicago over the weekend and
(01:20) I've been sort of out of the loop with what's going on and I need an update what are what are you seeing out there no well that's that's perfect and uh I'm getting ready to head out for a few days uh myself um on Thursday to the the Blue Ridge Mountains here in North Carolina haven't been there since the hurricane went through uh so interested to see how my old spots are doing um but it's always good to get away so happy to bring you up to speed um you know there's a lot going on and at the same time there's not right that the steady march higher in Bitcoin in equities uh
(01:58) gold has been on you know just a consolidation phase basically since it kind of blew up to 3500 um but given how fast and how strong that move was it actually is just a sign of strength to me that it's still you know holding well above 3,000 i think the days of 200 something gold are probably over i think I think if it ever gets there into five figures again it's not going to be for long with Bitcoin i think this this is a big move um you know people are going to look back at 110,000 Bitcoin just like
(02:35) they look back at 50,000 Bitcoin or 30,000 Bitcoin and say "Man I should have been buying there." Um you know we we've broken over uh the high set you know a few months ago i think that's now clearly you know a floor you know um support and you know I think the next upside target for me has always been that 150 range which I think you know I've been thinking 120 uh this month uh 150 is my call by the end of the year but really that's like a base case based on technical analysis i do that that is is a point where I reassess and and when I
(03:15) reassess it I have a feeling like um I'm going to pretty quickly come out with the target um around uh 190 195 as like a next upside target and you know we'll see when we get there but so just you know I think the best thing you can do actually for these markets is turn off your news because it's like last night I'm flipping between the channels and it's you know kurfles with Elon and Trump it's riots and fires and protests in LA it's um you know uh US behind the eightball with rare earth versus China um you know tariffs are
(03:56) going to start rolling into the inflation numbers uh job market only created 130ome thousand it's weak which I think is BS it's actually was a super strong report um there's been almost no government job creation since Trump took office so you essentially have to look and say well if every month under Biden there was like 40,000 government jobs and now that's not there i mean you take the 139 or whatever it was last week you had 40 you're up to about 180 you know which is really what the private sector is creating and it's doing that at a time where you have this demographic
(04:33) rollover where you have literally when you look at the unemployment reports which they break down you know foreignb born native born you know you have nativeorn you know people in the workforce declining and so if you're creating jobs I mean that that's why you're seeing you know the unemployment rate still 4.
(04:52) 2% so we've got a super strong job market we've got a consumer that is as unlevered as it has been in the last 20 years um you know you can't look at like credit card delinquencies or something like that you have to look at you know net worth you know yes is this skewed towards the wealthier you know 50% of America sure i mean the bottom 50% isn't exactly rolling in the dough but the top 20% certainly is especially when you factor in um over 12 trillion of tappable uh home equity um which I think is just now beginning to be tapped and and will begin getting tapped even
(05:35) more so um once the Fed fund funds rate goes down and I think it will um exactly how much and how quickly we can get into that too but I mean basically I guess where I'm going with all of this is the the doom and gloom you hear about whether you're scrolling through Twitter or turning on the news channels is masking what is an incredibly strong economy we've got an AI like super cycle boom going on we've got the blockchain and um all of that brings all of what that brings to financial services um you know uh counties or states in New Jersey
(06:12) now putting real estate deeds on the blockchain DeFi finally starting to happen in the real world stable coin bill um you know Bitcoin you know being part of the institutional investment mindset people understanding it more um I mean it it just all speaks to extreme bullishness and yet when you look at some of the surveys out there there's still net bearish you know like there's different sentiment gauges we were really really bearish we're still net bearish we're almost back to that median line uh you know overall and so we've got just people that are just doubters haters and you know which I think is
(06:53) great because it just means you know we've got a lot more to go yeah i'm very happy that you confirmed that being disconnected is probably the right move it's It's felt good not being in the day-to-day the actually the only day that I was really plugged in I was on a cross country flight and that was when Elon was having his his uh meltdown on X but that seems to have been brushed under the rug pretty quickly they were like "Okay damage control.
(07:24) " Uh it seems like they want to forget that that happened and pretend like it it never did but I think diving into you were mentioning this before we hit record how do rates play into this cuz looking at the 10-year at 4.47 30-year at 4.94 up over the last month but down from their highs intrammon and I think a lot of the focus of the doomers if you will is the elevated 10 year and 30-year and all the debt that needs to be rolled over how do you see that factoring into this outlook yeah I mean I I call it the rates -

2025-06-16 17:02:09What is KYC/AML?
- The acronym stands for Know Your Customer / Anti Money Laundering.
- In practice it stands for the surveillance measures companies are often compelled to take against their customers by financial regulators.
- Methods differ but often include: Passport Scans, Driver License Uploads, Social Security Numbers, Home Address, Phone Number, Face Scans.
- Bitcoin companies will also store all withdrawal and deposit addresses which can then be used to track bitcoin transactions on the bitcoin block chain.
- This data is then stored and shared. Regulations often require companies to hold this information for a set number of years but in practice users should assume this data will be held indefinitely. Data is often stored insecurely, which results in frequent hacks and leaks.
- KYC/AML data collection puts all honest users at risk of theft, extortion, and persecution while being ineffective at stopping crime. Criminals often use counterfeit, bought, or stolen credentials to get around the requirements. Criminals can buy "verified" accounts for as little as $200. Furthermore, billions of people are excluded from financial services as a result of KYC/AML requirements.
During the early days of bitcoin most services did not require this sensitive user data, but as adoption increased so did the surveillance measures. At this point, most large bitcoin companies are collecting and storing massive lists of bitcoiners, our sensitive personal information, and our transaction history.
Lists of Bitcoiners
KYC/AML policies are a direct attack on bitcoiners. Lists of bitcoiners and our transaction history will inevitably be used against us.
Once you are on a list with your bitcoin transaction history that record will always exist. Generally speaking, tracking bitcoin is based on probability analysis of ownership change. Surveillance firms use various heuristics to determine if you are sending bitcoin to yourself or if ownership is actually changing hands. You can obtain better privacy going forward by using collaborative transactions such as coinjoin to break this probability analysis.
Fortunately, you can buy bitcoin without providing intimate personal information. Tools such as peach, hodlhodl, robosats, azteco and bisq help; mining is also a solid option: anyone can plug a miner into power and internet and earn bitcoin by mining privately.
You can also earn bitcoin by providing goods and/or services that can be purchased with bitcoin. Long term, circular economies will mitigate this threat: most people will not buy bitcoin - they will earn bitcoin - most people will not sell bitcoin - they will spend bitcoin.
There is no such thing as KYC or No KYC bitcoin, there are bitcoiners on lists and those that are not on lists.

2025-06-17 15:47:27O Bitcoin é amplamente reconhecido como a primeira e mais importante inovação no campo das moedas digitais. Criado por Satoshi Nakamoto em 2009, ele estabeleceu as bases para um sistema financeiro descentralizado. Desde então, surgiram milhares de outras moedas digitais, muitas vezes referidas como criptomoedas ou até mesmo "shitcoins" por críticos que apontam sua volatilidade, falta de utilidade clara ou centralização. Essa comparação entre o Bitcoin e outras criptomoedas é essencial para entender os valores exclusivos que o Bitcoin representa.
O Bitcoin foi criado para ser uma alternativa ao sistema financeiro tradicional. Sua missão central é fornecer uma moeda descentralizada, resistente à censura e livre de intermediários como bancos ou governos.
Por outro lado, a maioria das outras criptomoedas/shitcoins surgiu com diferentes objetivos, que vão desde experimentos tecnológicos até planos de enriquecimento rápido. Muitas dessas moedas não têm a mesma descentralização e segurança do Bitcoin, sendo frequentemente geridas por equipes ou organizações centralizadas, o que as torna mais suscetíveis à manipulação e falhas de segurança.
Descentralização e segurança
Bitcoin: a rede Bitcoin é suportada por milhares de nós espalhados pelo mundo, garantindo verdadeira descentralização.
Seu algoritmo de consenso, Proof of Work (PoW), é amplamente testado e proporciona altos níveis de segurança contra ataques.
Não há controle centralizado, o que significa que nenhuma entidade pode alterar suas regras fundamentais.
Outras criptomoedas/shitcoins
Praticamente todas sacrificam descentralização em troca de velocidade ou funcionalidades adicionais.
Algumas utilizam mecanismos de consenso alternativos, como Proof of Stake (PoS), que, embora sejam mais eficientes em termos energéticos, são frequentemente criticados por favorecer a centralização e oferecer menor segurança.
Em muitos casos, há equipes de desenvolvimento centralizadas que podem modificar o código, criar mais unidades da moeda ou até encerrar o projeto, comprometendo a confiança dos usuários.
Oferta e escassez
Bitcoin: o Bitcoin tem uma quantidade limitada de 21 milhões de unidades, garantindo sua escassez.
Essa característica, junto com a crescente demanda, posiciona o Bitcoin como uma reserva de valor confiável, frequentemente comparado ao ouro digital.
Outras criptomoedas/shitcoins
Muitas não têm limites claros em sua oferta, resultando em inflação descontrolada.
Algumas “moedas” são intencionalmente inflacionárias, o que pode reduzir seu valor com o tempo.
Em muitos casos, essas “moedas” são pré-mineradas ou distribuídas de maneira desigual, favorecendo os criadores em detrimento da comunidade.
Finalidade e utilidade
Bitcoin: o Bitcoin é, acima de tudo, uma forma de dinheiro digital e reserva de valor.
Sua rede é confiável e simples, com o foco principal em ser um meio de troca e proteção contra a inflação.
Sua solidez o torna ideal para transações e armazenamento de valor a longo prazo.
Outras criptomoedas/shitcoins
Muitas shitcoins são apresentadas como soluções para casos específicos, como contratos inteligentes, jogos ou finanças descentralizadas.
Apesar de promessas ousadas, muitos falham em oferecer utilidade real ou em competir com soluções centralizadas já existentes.
Há um número considerável de projetos que não têm uma proposta clara e acabam sendo abandonados após um tempo de especulação.
Volatilidade e reputação
Bitcoin: embora o Bitcoin seja instável, ele é amplamente aceito como o padrão-ouro das moedas digitais.
Sua imagem foi construída ao longo de mais de dez anos de operação confiável e segurança comprovada.
Outras criptomoedas/shitcoins
Muitas shitcoins enfrentam alta volatilidade, frequentemente impulsionada por especulação ou manipulação de mercado.
A falta de clareza e as práticas duvidosas de alguns projetos prejudicam a imagem do setor como um todo.
Resistência à censura
Bitcoin: devido à sua descentralização e segurança, o Bitcoin é muito resistente à censura. Qualquer pessoa com acesso à internet pode participar da rede e fazer transações.
Outras criptomoedas/shitcoins
Muitas "shitcoins" dependem de estruturas centralizadas ou têm líderes identificáveis que podem ser pressionados por governos ou outros atores para censurar transações.
Resumindo, o Bitcoin continua sendo o líder indiscutível no mundo das moedas digitais devido à sua descentralização, segurança e escassez comprovada. Ele é um sistema feito para durar, oferecendo liberdade financeira e proteção contra a inflação.
Enquanto isso, muitas criptomoedas ou shitcoins não conseguem atingir os mesmos padrões de segurança e confiança, frequentemente priorizando velocidade, funções extras ou lucros especulativos rápidos. Para investidores e usuários, é importante distinguir entre o Bitcoin e os vários projetos alternativos, muitos dos quais podem não resistir ao teste do tempo.
O Bitcoin não só iniciou uma revolução financeira, mas continua sendo o padrão pelo qual todas as outras moedas digitais são medidas.
Muito obrigado por teres lido o texto até aqui, espero que esteja tudo bem contigo e um abraço enorme do teu madeirense bitcoiner maximalista favorito. Viva a liberdade!

2025-06-16 17:02:08The newly proposed RESTRICT ACT - is being advertised as a TikTok Ban, but is much broader than that, carries a $1M Fine and up to 20 years in prison️! It is unconstitutional and would create massive legal restrictions on the open source movement and free speech throughout the internet.
The Bill was proposed by: Senator Warner, Senator Thune, Senator Baldwin, Senator Fischer, Senator Manchin, Senator Moran, Senator Bennet, Senator Sullivan, Senator Gillibrand, Senator Collins, Senator Heinrich, and Senator Romney. It has broad support across Senators of both parties.
Corrupt politicians will not protect us. They are part of the problem. We must build, support, and learn how to use censorship resistant tools in order to defend our natural rights.
The RESTRICT Act, introduced by Senators Warner and Thune, aims to block or disrupt transactions and financial holdings involving foreign adversaries that pose risks to national security. Although the primary targets of this legislation are companies like Tik-Tok, the language of the bill could potentially be used to block or disrupt cryptocurrency transactions and, in extreme cases, block Americans’ access to open source tools or protocols like Bitcoin.
The Act creates a redundant regime paralleling OFAC without clear justification, it significantly limits the ability for injured parties to challenge actions raising due process concerns, and unlike OFAC it lacks any carve-out for protected speech. COINCENTER ON THE RESTRICT ACT

2025-06-16 17:02:07Bank run on every crypto bank then bank run on every "real" bank.
— ODELL (@ODELL) December 14, 2022
Good morning.
It looks like PacWest will fail today. It will be both the fifth largest bank failure in US history and the sixth major bank to fail this year. It will likely get purchased by one of the big four banks in a government orchestrated sale.
March 8th - Silvergate Bank
March 10th - Silicon Valley Bank
March 12th - Signature Bank
March 19th - Credit Suisse
May 1st - First Republic Bank
May 4th - PacWest Bank?PacWest is the first of many small regional banks that will go under this year. Most will get bought by the big four in gov orchestrated sales. This has been the playbook since 2008. Follow the incentives. Massive consolidation across the banking industry. PacWest gonna be a drop in the bucket compared to what comes next.
First, a hastened government led bank consolidation, then a public/private partnership with the remaining large banks to launch a surveilled and controlled digital currency network. We will be told it is more convenient. We will be told it is safer. We will be told it will prevent future bank runs. All of that is marketing bullshit. The goal is greater control of money. The ability to choose how we spend it and how we save it. If you control the money - you control the people that use it.

2025-06-16 17:02:07People forget Bear Stearns failed March 2008 - months of denial followed before the public realized how bad the situation was under the surface.
Similar happening now but much larger scale. They did not fix fundamental issues after 2008 - everything is more fragile.
The Fed preemptively bailed out every bank with their BTFP program and First Republic Bank still failed. The second largest bank failure in history.
There will be more failures. There will be more bailouts. Depositors will be "protected" by socializing losses across everyone.
Our President and mainstream financial pundits are currently pretending the banking crisis is over while most banks remain insolvent. There are going to be many more bank failures as this ponzi system unravels.
Unlike 2008, we have the ability to opt out of these broken and corrupt institutions by using bitcoin. Bitcoin held in self custody is unique in its lack of counterparty risk - you do not have to trust a bank or other centralized entity to hold it for you. Bitcoin is also incredibly difficult to change by design since it is not controlled by an individual, company, or government - the supply of dollars will inevitably be inflated to bailout these failing banks but bitcoin supply will remain unchanged. I do not need to convince you that bitcoin provides value - these next few years will convince millions.

2025-06-17 15:01:04This article was originally published on dev.to by satshacker.
Alright, you’ve built a useful and beautiful website, tool or app. However, monetization isn’t a priority and you’d rather keep the project free, ads-free and accessible?
Accepting donations would be an option, but how? A PayPal button? Stripe? Buymeacoffe? Patreon?
All of these services require a bank account and KYC verification, before you can send and receive donations – not very convenient.
If we only could send value over the internet, with just one click and without the need of a bank account…
Oh, hold on, that’s bitcoin. The decentralized protocol to send value across the globe. Money over TCP/IP.
In this article, we’ll learn how anyone can easily add a payment button or donation widget on a website or app.
Let’s get into it.
Introduction
Bitcoin is digital money that you can send and receive without the need for banks. While bitcoin is extremely secure, it’s not very fast. The maximum transactions per second (TPS) the network can handle is about 7. Obviously that’s not useful for daily payments or microtransactions.
If you’d like to dig deeper into how bitcoin works, a great read is “Mastering Bitcoin” by Andreas Antonopoulos.
Bitcoin vs Lightning
If you’d like to receive bitcoin donations “on-chain” all you need is a bitcoin wallet. You simply display your bitcoin address on your site and that’s it. You can receive donations.
It would look something like this; 1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa
Instead of showing the actual bitcoin address, you can also turn it into a QR code.
However, this is not a recommended solution. Using static on-chain addresses has two major downsides. It lowers privacy for you and your donnors and it’s a UTXO disaster because many small incoming transactions could beocme hard to consolidate in the future.
For donations and small transactions, the Lightning Network is the better option. Lightning allows for instant settlement with fees only a fraction of a cent.
Similar to bitcoin, you have the choice between non-custodial and custodial wallets. This means, either you have full control over your money or the wallet provider has.
Option 1: Lightning Address
With the lightning address feature, you an easily receive donations to an email like address.
It looks like this: yourname@wallet.com
Many wallets support lightning addresses and make it easy to create one. Then, you simple add the address to your donation page and you’re ready to receive tips.
You can also add a link link as in lightning:yourname@wallet.com and compatible lightning wallets and browser wallets will detect the address.
Option 2: Lightning Donation Widgets
If you like to take it a step further, you can also create a more enhanced donation checkout flow. Of course you could programm something yourself, there are many open source libraries you can build upon. If you want a simple plug-and-play solution, here are a couple of options:
Name
Type
Registration
SatSale
Self-hosted
No KYC
BTCPay Server
Self-hosted
No KYC
Pay With Flash
Widget
Email
Geyser Fund
Widget
Email
The Giving Block
Hosted
KYC
OpenNode
Hosted
KYC
SatSale (GitHub)
Lightweight, self-hosted Bitcoin/Lightning payment processor. No KYC.
Ideal for developers comfortable with server management. Simple to deploy, supports both on-chain and Lightning, and integrates with WooCommerce.
BTCPay Server
Powerful, open-source, self-hosted processor for Bitcoin and Lightning. No KYC.
Supports multiple currencies, advanced features, and full privacy. Requires technical setup and maintenance. Funds go directly to your wallet; great for those seeking full control.
Pay With Flash
Easiest for indie hackers. Add a donation widget with minimal code and no KYC. Payments go directly to your wallet for a 1.5% fee.
Setup Steps:
- Sign up at PayWithFlash.com
- Customize your widget in the dashboard
- Embed the code:
- Test to confirm functionality
Benefits:
- Minimal technical skills required
- Supports one-time or recurring donations
- Direct fund transfer, no intermediaries
Geyser Fund
Crowdfunding platform. Widget-based, connects to your wallet, email registration.Focused on Bitcoin crowdfunding, memberships and donations.
The Giving Block
Hosted, KYC required. Integrates with fiat and crypto, best for nonprofits or larger organizations.
OpenNode
Hosted, KYC required. Accept Bitcoin payments and donations; supports conversion to fiat, suitable for businesses and nonprofits.
Summary
- Fast, low-code setup: Use Pay With Flash or Geyser Fund.
- Privacy and control: Choose SatSale or BTCPay Server (requires technical skills).
- Managed, compliant solutions: The Giving Block or OpenNode.
Choose based on your technical comfort, privacy needs, and project scale.
I hope this article helped you. If you added bitcoin donations, share your link in the comments and I will send you a few satoshis maybe

2025-06-17 20:02:47When Richard Scotford moved to Costa Rica in 2018, he had no idea he would become a key figure in a thriving Bitcoin economy.
A longtime Bitcoin holder who initially saw it through the lens of speculation, Scotford’s journey led him to embrace Bitcoin’s deeper purpose and spearhead Bitcoin Jungle — a grassroots movement bringing real-world Bitcoin adoption to Costa Rica.
Bitcoin circular economies create holistic value for Bitcoiners
Bitcoin Jungle is inspired by Bitcoin Beach in El Salvador but uniquely adapted to Costa Rica’s economic landscape. Unlike El Salvador, where Bitcoin was positioned as a tool for financial inclusion, Costa Rica already has a fairly stable banking system.
The real issue? The friction of moving money. Expats, business owners, and tourists struggle with high fees, banking red tape, and slow transactions. Bitcoin helped solve a lot of these problems.
The Birth of Bitcoin Jungle
Scotford and his team launched Bitcoin Jungle in late 2021 with a simple goal: get bitcoin into people’s hands and make it usable. However, there was one challenge — he had no technical background.
Determined to create a circular bitcoin economy, Scotford networked aggressively. He attended the first Adopting Bitcoin conference in El Salvador, approaching strangers with his vision:
“I was just walking around trying to find people who could help me make this economy, going up to random people saying ‘Hey, what can you do? We’re trying to make a circular economy in Costa Rica, can you help us?’ They all thought I was crazy.”
The breakthrough came when he turned to Bitcoin Twitter. Nicolas Burtey from Galoy encouraged him to create a wallet, and developer Lee Salminen forked the Bitcoin Beach wallet for their project.
“Within two weeks of Adopting Bitcoin, Lee forked the Galoy Bitcoin Beach wallet, which took Galoy by surprise. Even though they made their wallet to be forked if necessary, I don’t think they were expecting people to do it so fast and, I’d like to say, so well. They were like, ‘Okay, cool, who are these guys doing this?’”
Finally Bitcoin Jungle had its own working wallet, surprising even the Galoy team with the speed of execution.
Grassroots Adoption: One Vendor at a Time
How do you build a bitcoin economy from scratch? Scotford’s answer was simple: start at the farmers’ markets.
“We were like, okay, we’re going to get all the bespoke niche market sellers who are in this area. We have all these beautiful farmers markets, and we decided to approach these people first,” Scotford explained.
His team took a strategic approach, targeting market gatekeepers first.
“If you want to talk to every individual person, it’s really difficult. But if you can talk to the person who is the owner of the market, and then they can introduce you to their market stores, you’re already halfway there.”
Going stall by stall, they pitched Bitcoin’s advantages — no bank fees and better payment options. But adoption didn’t happen overnight, so Bitcoin Jungle initially offered a safety net — vendors could cash out at the end of the day.
“We would say to the vendors, ‘Look, accept bitcoin, and at the end of the day, if you don’t want to keep the bitcoin, we’ll buy it off you,’” Scotford recalled.
“When we first started, maybe 30–40% of the vendors were cashing up every day or at the weekends. Lee would be walking around with big fistfuls of money, cashing out vendors.”
But over time, something shifted — they started keeping their bitcoin.
“Eventually, the vendors started to learn themselves that, ‘Oh, actually it’s better to keep it.’ They would then pay for their tables in the markets using bitcoin. They thought, ‘Well, I don’t want to keep this bitcoin, I don’t really know what to do with it, but I can pay for my table.’ So there, the circular economy starts to happen.”
Today, Bitcoin Jungle runs with minimal intervention, and Scotford takes pride in their reliability.
“When you come here to Costa Rica, what we really pride ourselves on is that if someone says they accept bitcoin, 99% of the time, they will. And if they’re part of Bitcoin Jungle, they will 100% accept bitcoin and you will have a fluid experience with it.”
By mid-summer 2024 over 380 locations in Costa Rica accepted bitcoin
The Bitcoin Jungle Wallet and Real Usage
Bitcoin Jungle is an open-source community project built on the Bitcoin Lightning Network.
Acting as a community bank, the project processes a large number of transactions daily. To encourage proper security practices, Scotford’s team alerts their peers, reminding users to move their bitcoin to cold storage.
“If you’ve got too much bitcoin on your wallet, we send you a message telling you to move it to cold storage,” he explained. For larger businesses, they even offer hands-on assistance to secure funds properly.
Unlike the HODL-only philosophy that many Bitcoiners advocate, Bitcoin Jungle encourages spending.
“Michael Saylor says don’t spend your bitcoin. We say the opposite,” Scotford laughed. “We’re the antithesis of that. You need to spend it.”
Bitcoin Jungle’s Unique Approach to Costa Rica
Bitcoin Jungle isn’t just another Bitcoin adoption effort; it’s tailored to Costa Rica’s economy. The wallet operates in Costa Rican colónes, making transactions feel familiar to residents while ensuring tourists and expats can still interact easily.
The team has also introduced low-fee bitcoin ATMs, point-of-sale integrations, and partnerships that allow users to pay in bitcoin while the recipient receives local currency.
A major breakthrough came when Francis Pouliot from Bull Bitcoin joined forces with Bitcoin Jungle, bringing his expertise in banking infrastructure to the project.
This collaboration enabled seamless bitcoin payments that integrate directly with Costa Rica’s financial system, allowing users to pay anyone, even businesses that don’t directly accept bitcoin, while the recipient receives funds in colónes or dollars.
“I can go to a hardware store, order steel for my new basketball court, pay in bitcoin, and the store gets dollars,” Scotford said. “For a non-tech guy like me, it’s magical.”
Why Aren’t There More Bitcoin Jungles?
Scotford sees an opportunity for more localized bitcoin economies.
“There should be a Bitcoin Harbor, a Bitcoin Mountain, a Bitcoin Driveway,” he joked. “But instead of waiting for permission or corporate funding, people need to take action themselves.”
He emphasizes that building a circular bitcoin economy doesn’t require deep pockets. “I probably gave away $600 worth of bitcoin when we started — just $3 here, $4 there — to get people using it.”
The Future of Bitcoin Jungle
Bitcoin Jungle continues to grow, recently hosting events like the Bitcoin Freedom Festival and integrating bitcoin into community projects, including a school where tuition can be paid in bitcoin.
“The institutions have come in, but the grassroots projects haven’t caught up,” Scotford observed. “It’s time for people to stop sitting on their hands and start building.”
Bitcoin is permissionless, no one has to wait for approval to start using it. Bitcoin Jungle proves that with vision and persistence, anyone can build a thriving Bitcoin economy, one market stall at a time.

2025-06-17 20:02:27Years ago, I flew a microlight aircraft for the first time and felt what it meant to leave the ground. Recently, I bought a gigabyte of storage for 5 cents via Lightning, and something similar happened. This is about that moment—when you stop believing something works and start knowing it does.
Every now and then (if you’re lucky) you have one of those “eureka” moments where the full implications of something hit you for the first time. My biggest experience of that was years ago when I got a microlight aircraft. They’d just come out, so there were no regulations, and anyone could buy one and just fly.
People who should never be flying were going all over the place, and—having no navigation training—they were following motorways instead. Some were even landing at the service stops to get more fuel. How could I resist?
The price included training at an old airfield that was now not busy at all. After a lot of taxiing along the runways, it came time to try a takeoff. Nothing can prepare you for that. It’s not like a Cessna or any of those “proper” aircraft; it’s just an aluminum frame, and you hang off the center of the main pole, the center of gravity. There was a twin motor behind me, totaling 250 cc. I could feel where the wind was on the wings, which side, and even how far along. It was an insight into what birds must feel. I’d trade wings for a big brain any day!
I hit the gas on full, and we accelerated. I had been told that this thing could fly. and had seen my teacher fly in it many times. I thought I understood that it could fly, but as I left the ground and the drag on the wheels was suddenly gone, the whole thing lurched up into the air fast, at a really steep angle, and before I could think, I was already higher than a house. That was when I understood that this thing could fly. Belief is not knowledge, and knowledge only comes from experience.
So it is with many things. So it is with Bitcoin and the Lightning Network. I believed that Lightning could “transform the economic landscape.” I had read about how bitcoin can “revolutionize the financial system.” What hadn’t happened yet was that I had not actually experienced it. That take-off moment came when someone sent me a file link on a CDN. I downloaded the PDF (300 MB or so) and then cut the end off the URL to have a look at the service provider.
To my surprise, they were offering storage space on the CDN at 5c per gigabyte per month. with “unlimited” data transfer. So I decided to try it out. Within a few seconds I had ordered, paid for, and received my credit, and the service was available. 5 cents! That was when I realized how simple everything else in the world can be with Bitcoin and the Lightning Network.
Who cares about how many stupid dollars you can get with bitcoin? Look at what you can do with it! In the new world that may be opening up for us, we can rid ourselves of the parasites who have held us back for so long. “When moon?” takes on a whole different meaning. Nothing is beyond our reach.
There was no bitcoin back in the Spanish Civil War when Durruti was doing his thing, but something of the same awakening must have stirred in him to inspire these words: “We should not be in the least afraid of ruins. They may blast and lay bare this world before they go, but we carry a new world here in our hearts, and this world is growing as we speak.”
https://satellite.earth is the site. It’s not just a storage provider; it’s a Nostr node you can use like any other node, and it has communities set up, among other things. It’s well worth a look. No, I’m not getting paid; they don’t even know me. And I’m not sure, but it looks like because I haven’t used the whole 1 GB yet, they are using my 5c to extend the time I have. In other words, it’s 5c per gigabyte-month, not per gigabyte per month.

2025-06-17 16:40:27Know Your Customer is a regulation that requires companies of all sizes to verify the identity, suitability, and risks involved with maintaining a business relationship with a customer. Such procedures fit within the broader scope of anti-money laundering (AML) and counterterrorism financing (CTF) regulations.
Banks, exchanges, online business, mail providers, domain registrars... Everyone wants to know who you are before you can even opt for their service. Your personal information is flowing around the internet in the hands of "god-knows-who" and secured by "trust-me-bro military-grade encryption". Once your account is linked to your personal (and verified) identity, tracking you is just as easy as keeping logs on all these platforms.
Rights for Illusions
KYC processes aim to combat terrorist financing, money laundering, and other illicit activities. On the surface, KYC seems like a commendable initiative. I mean, who wouldn't want to halt terrorists and criminals in their tracks?
The logic behind KYC is: "If we mandate every financial service provider to identify their users, it becomes easier to pinpoint and apprehend the malicious actors."
However, terrorists and criminals are not precisely lining up to be identified. They're crafty. They may adopt false identities or find alternative strategies to continue their operations. Far from being outwitted, many times they're several steps ahead of regulations. Realistically, KYC might deter a small fraction – let's say about 1% ^1 – of these malefactors. Yet, the cost? All of us are saddled with the inconvenient process of identification just to use a service.
Under the rhetoric of "ensuring our safety", governments and institutions enact regulations that seem more out of a dystopian novel, gradually taking away our right to privacy.
To illustrate, consider a city where the mayor has rolled out facial recognition cameras in every nook and cranny. A band of criminals, intent on robbing a local store, rolls in with a stolen car, their faces obscured by masks and their bodies cloaked in all-black clothes. Once they've committed the crime and exited the city's boundaries, they switch vehicles and clothes out of the cameras' watchful eyes. The high-tech surveillance? It didn’t manage to identify or trace them. Yet, for every law-abiding citizen who merely wants to drive through the city or do some shopping, their movements and identities are constantly logged. The irony? This invasive tracking impacts all of us, just to catch the 1% ^1 of less-than-careful criminals.
KYC? Not you.
KYC creates barriers to participation in normal economic activity, to supposedly stop criminals. ^2
KYC puts barriers between many users and businesses. One of these comes from the fact that the process often requires multiple forms of identification, proof of address, and sometimes even financial records. For individuals in areas with poor record-keeping, non-recognized legal documents, or those who are unbanked, homeless or transient, obtaining these documents can be challenging, if not impossible.
For people who are not skilled with technology or just don't have access to it, there's also a barrier since KYC procedures are mostly online, leaving them inadvertently excluded.
Another barrier goes for the casual or one-time user, where they might not see the value in undergoing a rigorous KYC process, and these requirements can deter them from using the service altogether.
It also wipes some businesses out of the equation, since for smaller businesses, the costs associated with complying with KYC norms—from the actual process of gathering and submitting documents to potential delays in operations—can be prohibitive in economical and/or technical terms.
You're not welcome
Imagine a swanky new club in town with a strict "members only" sign. You hear the music, you see the lights, and you want in. You step up, ready to join, but suddenly there's a long list of criteria you must meet. After some time, you are finally checking all the boxes. But then the club rejects your membership with no clear reason why. You just weren't accepted. Frustrating, right?
This club scenario isn't too different from the fact that KYC is being used by many businesses as a convenient gatekeeping tool. A perfect excuse based on a "legal" procedure they are obliged to.
Even some exchanges may randomly use this to freeze and block funds from users, claiming these were "flagged" by a cryptic system that inspects the transactions. You are left hostage to their arbitrary decision to let you successfully pass the KYC procedure. If you choose to sidestep their invasive process, they might just hold onto your funds indefinitely.
Your identity has been stolen
KYC data has been found to be for sale on many dark net markets^3. Exchanges may have leaks or hacks, and such leaks contain very sensitive data. We're talking about the full monty: passport or ID scans, proof of address, and even those awkward selfies where you're holding up your ID next to your face. All this data is being left to the mercy of the (mostly) "trust-me-bro" security systems of such companies. Quite scary, isn't it?
As cheap as $10 for 100 documents, with discounts applying for those who buy in bulk, the personal identities of innocent users who passed KYC procedures are for sale. ^3
In short, if you have ever passed the KYC/AML process of a crypto exchange, your privacy is at risk of being compromised, or it might even have already been compromised.
(they) Know Your Coins
You may already know that Bitcoin and most cryptocurrencies have a transparent public blockchain, meaning that all data is shown unencrypted for everyone to see and recorded forever. If you link an address you own to your identity through KYC, for example, by sending an amount from a KYC exchange to it, your Bitcoin is no longer pseudonymous and can then be traced.
If, for instance, you send Bitcoin from such an identified address to another KYC'ed address (say, from a friend), everyone having access to that address-identity link information (exchanges, governments, hackers, etc.) will be able to associate that transaction and know who you are transacting with.
Conclusions
To sum up, KYC does not protect individuals; rather, it's a threat to our privacy, freedom, security and integrity. Sensible information flowing through the internet is thrown into chaos by dubious security measures. It puts borders between many potential customers and businesses, and it helps governments and companies track innocent users. That's the chaos KYC has stirred.
The criminals are using stolen identities from companies that gathered them thanks to these very same regulations that were supposed to combat them. Criminals always know how to circumvent such regulations. In the end, normal people are the most affected by these policies.
The threat that KYC poses to individuals in terms of privacy, security and freedom is not to be neglected. And if we don’t start challenging these systems and questioning their efficacy, we are just one step closer to the dystopian future that is now foreseeable.

2025-06-17 21:01:40The Thai government has eliminated taxes on gains from cryptocurrencies until 2029 to attract investors and promote the digital asset sector.
According to Efinance Thai, Thailand has approved a five-year tax exemption on profits from the sale of Bitcoin and other digital assets. The decision aims to position the country as one of the world’s leading digital financial hubs.
On June 17, Thailand’s Cabinet officially approved the tax measure proposed by the Ministry of Finance. The initiative removes personal income tax on capital gains from the sale of cryptocurrencies conducted through licensed operators under the 2018 Digital Asset Business Act.
Deputy Finance Minister Julapun Amornvivat stated that the tax policy is a cornerstone of the government’s strategy to turn Thailand into a major global center for Bitcoin and blockchain-based financial services.
The capital gains tax exemption will be in effect from January 1, 2025, to December 31, 2029. It applies exclusively to transactions carried out via exchanges, brokers, and dealers licensed and regulated by Thailand’s Securities and Exchange Commission (SEC).
Thai authorities estimate that this tax reform will boost the domestic Bitcoin market, generating positive spillovers for the country’s innovative tech ecosystem. Economic projections indicate a medium-term increase in tax revenues of at least 1 billion baht (around $30 million), driven by sector growth and fresh investment inflows.
According to the government, the initiative is also expected to encourage capital raising through digital tokens and foster the development of blockchain-based financial services.

2025-06-17 20:05:43The boy left the piano and ran toward his parents. "Shall we play another song?" In one of those surprisingly magical moments, the three of them were playing together, pretending to be a band: the father with the trumpet, playing distractedly while checking messages on his phone; the mother with the guitar, smiling and listening attentively; the son with the piano, happy. Stumbles in the notes, laughter, joy. "Tomorrow is Monday," she remembered. They stopped and put away the instruments—they could do it another time. There was time. There's always more time, right?
That night, like any other on a typical week, they fulfilled the ritual of dinner at eight, a shower before bed, getting the uniform and backpack ready. Afterward, the quick hug to the father and the long kiss to the mother. In turn, the parents continued with their own routine: checking emails, reading for a while. He went to sleep while she logged on to her computer to teach an online class. The nocturnal silence took over the house, interrupted only by the occasional comment from her lesson.
The scream startled her. Was it coming from a neighbor's house? No, it couldn't be. That slight sensation in her chest, that anguish... She decided to go see how her only son was doing. When she was about to reach the second floor, she heard some moaning. She ran to the room. Her boy, curled up in a ball, and beside the bed, vomit. The forehead first—it was burning—then the abdomen. Another scream tore through her. The father woke up and approached to ask what was happening. "I don't know. Go to sleep, I'll handle it." How many other times had she said that? Without thinking, without considering the weight of the tacit agreement between them, of the comfortable distance he called space.
She lifted her son in her arms, covered him with a blanket, and took him to the emergency room. The bright lights of triage, the familiar waiting, then nurse, and finally, doctor. She knew the procedure by heart. She was always the one who handled these emergencies, who knew the nurses, who knew his medical history —allergies, previous injuries. "The experience of having an athlete son," she used to say. During the examination, the boy remained curled up. "It looks like acute appendicitis," the doctor said. "We need an urgent ultrasound and blood work."
The mother grew impatient between her child's suffering and the staff's slowness. She demanded faster attention, called the nurses over and over. "The CT scan shows perforation with fluid in the abdomen," she heard afterward. "He needs surgery now." When they came rushing and took him, while she waited for the results... it had been because of her demands, surely. She never thought she wouldn't see him again. How could she imagine that emptiness that would take over her chest, to the point of not being able to breathe?
They called the father. He arrived disoriented, like someone arriving in unknown territory, and somewhat worried, not much, because he was used to her taking care of things. The father listened to the doctor's explanation with a distorted face. "I'm very sorry. There were complications. The perforation caused severe sepsis." The man let out a scream that echoed throughout the entire hallway: "He died alone, my God, he died alone." It was the first time in years that he expressed something so profound, and it came too late. A postponed fatherhood concentrated in an instant.
Hadn't the mother been with her son until they took him away? Or the doctor and staff in the operating room? He didn't ask about her, didn't look for her. She wanted to speak, but the words wouldn't come out. If she hadn't been at the hospital, perhaps no one would have comforted her in that terrible moment. She moved because she had to, responded because they asked her. From that night she would only remember her son's face and small hands when she let them go for the last time. Afterward, only the reconstruction of events through the eyes of others: her sister and her parents.
Who thinks about when it will be the last time for anything? The last chess game with the father, the last dinner out with the mother, the last birthday of the favorite aunt. The last frightened squeeze of a small child's hand. They hadn't paid attention. Why would they? You always think there's more time.
The days that followed blurred into a hazy sequence of impossible decisions. Arrangements had to be made. At first, everything seemed suspended, even sadness. A family eclipse where darkness takes everything. You know it's temporary, but you can't glimpse the light. The family gropes around like blind people, and slowly grief sprouts. Decisions are made that will be forgotten: how to tell others, who will speak and who won't. An endless series of unimportant actions in the face of pain invading everything, little by little, to then explode like a volcano. The siblings of both parents and the grandparents crying. The parents in black silence.
The funeral passed. The weeks passed. For the mother, everything was now subordinated to the memory of an ancient life. The habit of picking him up after school or some activity outside, seeing him walk toward the car, seeing him walk away. His voice. His smell. He still smelled like a child—he was still a few months away from his eleventh birthday. He was still her little one. She could take his hand to cross the street, give him a long hug just because, plant a kiss on his cheek. He didn't impose that distance that comes when children start becoming men. Her boy, the storyteller of the childhood world... had departed.
As the months passed, the father withdrew more and more. He came home later and later, hardly spoke. He avoided talking to her. Sometimes, she found him crying in the boy's room. The fragility became evident and the limited kindnesses from one to the other disappeared. The one who was barely there was no longer there. The bridge between two solitudes had disappeared. The family had also died, and so, simply, one afternoon, he didn't return. Without words, without farewell.

Why did Elon buy twitter for $44 Billion? What value does he see in it besides the greater influence that undoubtedly comes with controlling one of the largest social platforms in the world? We do not need to speculate - he made his intentions incredibly clear in his first meeting with twitter employees after his takeover - WeChat of the West.
To those that do not appreciate freedom, the value prop is clear - WeChat is incredibly powerful and successful in China.
To those that do appreciate freedom, the concern is clear - WeChat has essentially become required to live in China, has surveillance and censorship integrated at its core, and if you are banned from the app your entire livelihood is at risk. Employment, housing, payments, travel, communication, and more become extremely difficult if WeChat censors determine you have acted out of line.
The blue check is the first step in Elon's plan to bring the chinese social credit score system to the west. Users who verify their identity are rewarded with more reach and better tools than those that do not. Verified users are the main product of Elon's twitter - an extensive database of individuals and complete control of the tools he will slowly get them to rely on - it is easier to monetize cattle than free men.
If you cannot resist the temptation of the blue check in its current form you have already lost - what comes next will be much darker. If you realize the need to resist - freedom tech provides us options.

2025-06-17 16:40:22Bitcoin enthusiasts frequently and correctly remark how much value it adds to Bitcoin not to have a face, a leader, or a central authority behind it. This particularity means there isn't a single person to exert control over, or a single human point of failure who could become corrupt or harmful to the project.
Because of this, it is said that no other coin can be equally valuable as Bitcoin in terms of decentralization and trustworthiness. Bitcoin is unique not just for being first, but also because of how the events behind its inception developed. This implies that, from Bitcoin onwards, any coin created would have been created by someone, consequently having an authority behind it. For this and some other reasons, some people refer to Bitcoin as "The Immaculate Conception".
While other coins may have their own unique features and advantages, they may not be able to replicate Bitcoin's community-driven nature. However, one other cryptocurrency shares a similar story of mystery behind its creation: Monero.
History of Monero
Bytecoin and CryptoNote
In March 2014, a Bitcointalk thread titled "Bytecoin. Secure, private, untraceable since 2012" was initiated by a user under the nickname "DStrange"^1^. DStrange presented Bytecoin (BCN) as a unique cryptocurrency, in operation since July 2012. Unlike Bitcoin, it employed a new algorithm known as CryptoNote.
DStrange apparently stumbled upon the Bytecoin website by chance while mining a dying bitcoin fork, and decided to create a thread on Bitcointalk^1^. This sparked curiosity among some users, who wondered how could Bytecoin remain unnoticed since its alleged launch in 2012 until then^2^.
Some time after, a user brought up the "CryptoNote v2.0" whitepaper for the first time, underlining its innovative features^4^. Authored by the pseudonymous Nicolas van Saberhagen in October 2013, the CryptoNote v2 whitepaper^5^ highlighted the traceability and privacy problems in Bitcoin. Saberhagen argued that these flaws could not be quickly fixed, suggesting it would be more efficient to start a new project rather than trying to patch the original^5^, an statement simmilar to the one from Satoshi Nakamoto^6^.
Checking with Saberhagen's digital signature, the release date of the whitepaper seemed correct, which would mean that Cryptonote (v1) was created in 2012^7^, although there's an important detail: "Signing time is from the clock on the signer's computer" ^9^.
Moreover, the whitepaper v1 contains a footnote link to a Bitcointalk post dated May 5, 2013^10^, making it impossible for the whitepaper to have been signed and released on December 12, 2012.
As the narrative developed, users discovered that a significant 80% portion of Bytecoin had been pre-mined^11^ and blockchain dates seemed to be faked to make it look like it had been operating since 2012, leading to controversy surrounding the project.
The origins of CryptoNote and Bytecoin remain mysterious, leaving suspicions of a possible scam attempt, although the whitepaper had a good amount of work and thought on it.
The fork
In April 2014, the Bitcointalk user
thankful_for_today
, who had also participated in the Bytecoin thread^12^, announced plans to launch a Bytecoin fork named Bitmonero^13^.The primary motivation behind this fork was "Because there is a number of technical and marketing issues I wanted to do differently. And also because I like ideas and technology and I want it to succeed"^14^. This time Bitmonero did things different from Bytecoin: there was no premine or instamine, and no portion of the block reward went to development.
However, thankful_for_today proposed controversial changes that the community disagreed with. Johnny Mnemonic relates the events surrounding Bitmonero and thankful_for_today in a Bitcointalk comment^15^:
When thankful_for_today launched BitMonero [...] he ignored everything that was discussed and just did what he wanted. The block reward was considerably steeper than what everyone was expecting. He also moved forward with 1-minute block times despite everyone's concerns about the increase of orphan blocks. He also didn't address the tail emission concern that should've (in my opinion) been in the code at launch time. Basically, he messed everything up. Then, he disappeared.
After disappearing for a while, thankful_for_today returned to find that the community had taken over the project. Johnny Mnemonic continues:
I, and others, started working on new forks that were closer to what everyone else was hoping for. [...] it was decided that the BitMonero project should just be taken over. There were like 9 or 10 interested parties at the time if my memory is correct. We voted on IRC to drop the "bit" from BitMonero and move forward with the project. Thankful_for_today suddenly resurfaced, and wasn't happy to learn the community had assumed control of the coin. He attempted to maintain his own fork (still calling it "BitMonero") for a while, but that quickly fell into obscurity.
The unfolding of these events show us the roots of Monero. Much like Satoshi Nakamoto, the creators behind CryptoNote/Bytecoin and thankful_for_today remain a mystery^17^, having disappeared without a trace. This enigma only adds to Monero's value.
Since community took over development, believing in the project's potential and its ability to be guided in a better direction, Monero was given one of Bitcoin's most important qualities: a leaderless nature. With no single face or entity directing its path, Monero is safe from potential corruption or harm from a "central authority".
The community continued developing Monero until today. Since then, Monero has undergone a lot of technological improvements, migrations and achievements such as RingCT and RandomX. It also has developed its own Community Crowdfundinc System, conferences such as MoneroKon and Monerotopia are taking place every year, and has a very active community around it.
Monero continues to develop with goals of privacy and security first, ease of use and efficiency second. ^16^
This stands as a testament to the power of a dedicated community operating without a central figure of authority. This decentralized approach aligns with the original ethos of cryptocurrency, making Monero a prime example of community-driven innovation. For this, I thank all the people involved in Monero, that lead it to where it is today.
If you find any information that seems incorrect, unclear or any missing important events, please contact me and I will make the necessary changes.

2025-06-17 11:02:38People forget Bear Stearns failed March 2008 - months of denial followed before the public realized how bad the situation was under the surface.
Similar happening now but much larger scale. They did not fix fundamental issues after 2008 - everything is more fragile.
The Fed preemptively bailed out every bank with their BTFP program and First Republic Bank still failed. The second largest bank failure in history.
There will be more failures. There will be more bailouts. Depositors will be "protected" by socializing losses across everyone.
Our President and mainstream financial pundits are currently pretending the banking crisis is over while most banks remain insolvent. There are going to be many more bank failures as this ponzi system unravels.
Unlike 2008, we have the ability to opt out of these broken and corrupt institutions by using bitcoin. Bitcoin held in self custody is unique in its lack of counterparty risk - you do not have to trust a bank or other centralized entity to hold it for you. Bitcoin is also incredibly difficult to change by design since it is not controlled by an individual, company, or government - the supply of dollars will inevitably be inflated to bailout these failing banks but bitcoin supply will remain unchanged. I do not need to convince you that bitcoin provides value - these next few years will convince millions.

2025-06-17 19:05:21Shabbat Shalom, y'all.
At the time of writing and releasing this, it happened to be a Lunar Shabbat, which is actually Torah (much to the chagrin of those who practice Shabbat on a Saturday or Sunday exclusively). The Shabbat is always on the 8th, 15th, 22nd, and 29th days of a Hebrew Calendar month, which almost nobody follows anymore. I started doing this a few months ago, and it's made me see the Torah for what it really is.
To the topic at hand, though. A lot of people on Nostr don't seem to understand the historical narrative of the book of Revelation, which saddens me, as we're in the end times Ekklesia (Assembly) era of Laodecia.
Deception of Bible Translations
First off, the reason why most people trust their pastors and/or read differently to what I do in Nazaritic circles is because of translations of the Scriptures that are evil, wretched and Catholic. The best way to combat this is to make some recommendations of which versions you'll want to use that aren't Catholic-infested.
These are the ONLY recommended versions to read. Anythine else is bupkus, evil and garbage, and will teach you futrism or preterism, both of which are Jesuit-penned deceptions.
The recommended versions are as follows:
-
1560/1590 Geneva (GNV)
-
Young's Literal Translation (YLT)
These are versions I've read, and determined are evil, wretched and garbage:
-
New International Version (NIV) [Fun fact: The publisher of the NIV, Zondervan, has a sister publisher that is behind the Satanic Bible's publishing]
-
New Living Translation (NLT)
-
English Standard Version (ESV)
-
ISR The Scriptures 2009 Third Edition with Minor Revisions [2016] (ISR2009)
-
New American Standard Bible (NASB)
-
New King James Version (NKJV)
-
KJV 1611 (Apparently, it was made for control)
What is the Laodecia Era for the Ekklesia?
As a refresher, this time sees people saying they're rich in truth and that they have need of nothing, but this shows that they're wretched, miserable, naked and wicked. Why is this? The need of nothing points to not needing another explanation other than the false futuristic viewpoint, whereas being rich is connected to already knowing the truth about the historical fulfillment of Revelation, which many people don't know at all. I seriously grieve their loss, for they know not what they do.
I'm also new into this viewpoint, and most of what I'll be talking about is proven by historicist prophet David Nikao Wilcoxson on YouTube and Facebook (I don't use Facebook). This single Nostr article, I pray, is the starting point for understanding why I call out what I call out, and the patterns I see pointing to the Roman Catholic Church (the Tares) and the Jesuit Order (the current rulers of our world, the Earth Beast of Rev. 13) being the harlots that will be plucked out before Messiah's return.
The 70th Week of Daniel
Let us start first with the 70th Week of Daniel, which futurists believe is pointed towards a 7 year period where a one-man antichrist makes a peace deal for Israel.
This was proven to be untrue, as this is a deception that many people have fallen for, thus obeying the Pope (the Mark of the Beast on the right hand). What Daniel was talking about was not the end times, but rather, two-fold. The first is that he was asking about when Yevah would free the Jews from slavery (since they were in the Babylonian Beast Kingdom at this time). The second is when Messiah would come in the flesh and start a 7 year period from 27-34 AD, which is the final 7 year period of this 490 year cycle. King Artaxerxes I would go ahead and call for the rebuilding of Jerusalem in 476 BC (as is seen in Ezra), which would be the first 7 weeks (the first 7 Shemita [Shabbat year] cycles). Afterwords, we would see another 62 weeks (this period is a slient period), and then another period of 1 week. This week points to Messiah's ministry and death.
3 1/2 years into this 70th week (in 31 AD) is when Messiah would be nailed to the cross on March 13 of 31 AD (I'm still debating if the cross is a symbol of Tammuz or not). This was Passover in the Hebrew calendar year of 3790. He was 33 years of age when he was nailed, and then rose again 3 days later (on the 17th of Nisan in 3790). That Passover fell on a Monday (when the Romans were using the 8-day calendar instead of the 7-day calendar we've essentially been forced to use).
To prove the above, Wilcoxson had produced a series of videos regarding the 70th Week of Daniel (that being the 70th Week of Daniel Decoded series), which I would recommend you watch. You'll also want to find an audiobook version of Seventy Weeks: The Historical Alternative produced by Tearing Down Idols. These are the two pieces of proof I have to show this. Speaking of Wilcoxson, he had already produced books on these matters, as understanding the hostorical narrative of the Scriptures is the key to making war with the Roman Catholic Church and the Jesuit Order, especially now that we're in Laodecia.
The Olivet Discourse
The second part of this trifecta has to do with the Olivet Discourse of Matthew 23, which points to the destruction of Jarusalem by Rome for Israel's unfaithfulness to Yevah's instructions. Now, there are connections to parables that basically talk about the Yewish (Yew as in Yewtree worship) leaders (particulaly the Pharisees and Saducees) practicing the Tradition of the Elders (which are the Babylonian Talmud and the Egyptian Kabbalah of today), and for not understanding that this was Messiah, they were destroyed for their iniquities. I don't care to research the futurist narrative on this, as I know it is full of twisted words and word salad sorcery.
Wilcoxson proves what I've said in the Olivet Discourse Decoded series of videos, so that's where I'll point you to when you have an open heart, open eyes and open ears. Many futurists won't, because they are exactly what Messiah described in the Ekklesia era of Laodecia.
Revelation and Its Prophecies
Finally, there's Revelation (what used to be called Apocalypse). When looking into this book, you realize that it's really a 4-layered war manual for how to fight this war against the Roman Catholic leadership and the Jesuit Order. This also shows how you can harvest souls (the harvest points to a mass exodus of Roman Catholicism membership). This I will go in depth on, and will even have passages to back this up.
Layer 1: The Roman Beast Kingdom
The first layer of this 4-layered manual shows the phases of the Roman Empire, which never really disappeared. Rev. 12 described the Roman Empire, which was used to wipe out the early Ekklesia (the woman), murdering millions of Nazarites. The Seals point to the incline (for the Four Horsemen of the Apocalypse) and decline of the Roman Empire (the other three Seals), while the Trumpets point to the official Roman Empire's downfall. This would be split into 10 separate kingdoms in Europe, which would be countered by the creation of Christianity, which is really any of the 44k+ forks of Roman Catholicism. This was done to destroy the Ekklesia, as the Roman Catholic Church is the Tare field that Messiah had talked about in the parable of the Wheat and the Tares.
Staying in this layer, the Sea Beast is the next phase. This is the 1,260-year reign of the Pope (538-1798), as he was the one who plucked out 3 kingdoms who didn't bow to his authority (the Heruli, the Huns and the Ostrigoths). Keep in mind that this started after the removal of the restrainer in 476 (pointing to the removal of the final Western Roman Emperor), and healed the deadly head wound (pointing to the Pope rising to power out of a sea of people). During this reign, he took the title of Pontifex Maximus, as he had civic and ecclesiastical power over everyone. This would be the healing of the deadly head wound, as shown earlier in this beast. He would pretend to be the leader of the Ekklesia, thus sitting in the Temple of Yevah, though he's the son of perdition, as he proclaims to be Yevah, forgive sins and provide salvation through works alone, which is blasephemous to begin with. The persecution of the Nazarites also prove them to be anti-Moshiach (Messiah). They also have the title of Vicar of Christ, which in the Latin is Vicarus Filii Dei, which is equal to 666 when calculated using a form of gematria I have no idea about. He would ultimately be removed from power by the Earth Beast in 1798, after he basically limited the power of the Jesuit Superior General and his minions. As stated before, the Mark of the Beast is reverence (forehead) and obeisance (right hand) to the Pope.
Finally, the Earth Beast of Revelation 13 points to the Jesuit Superior Geneal rising out of the earth (which is the land) of the Antichrist Beast Pope, the Vatican. These two horns pretend to serve Messiah (lamb) but are really Lucifarians (the dragon), serving Lucifer. The Black Pope, as the Jesuit Superior General is called, used his power to gether the world under him. That's why he uses Washington D.C. (the District of the Roman goddess, Columbia), his war machine (Military Indurstial Complex), to overthrow leaders who won't bow to his authority and those who won't set up a Rothschild central bank; much less obey the Khazars, who he also controls (I happened to be a partial German Khazar who escaped the grasp of the Black Pope as best as I know thus far).
Layer 2: The Ekklesia Eras
Now comes the eras of the Ekklesia. There are seven of them, though I've already explained the era of Laodecia. How about I give a quick explanation of the first six eras, like so?
Ephesus would spread the gospel in the Roman Empire, with their love growing cold when Messiah didn't return.
Smyrna had 10 years of persecutions from 303-312, which is what the 5th seal points to.
Pergamos would fall away (2 Thess. 2) from the Scriptures when compromising with Rome (Mark of the Beast as I had explained)
Thyatira means ruled by a woman. This means, the Roman Catholic Church would do this, as the Popes sought to eliminate the two witnesses, which are the Nazarites and the printed Scriptures (the little book or Rev. 10). This was why they killed the Nazarites and bured the printed Scriptures ruthlessly enough, that they were classified as "dead" in 1514. The Popes would hold great feasts to celebrate the removal of the two witnesses after they got all of Christendom under their control.
Sardis means escaping one, which points to Messiah calling them dead after 3 1/2 years from the Pope's classification of the death of the two witnesses. Luther's 95 Thesis sparked the Protestant Reformation, which would lead to the resurrection of the two witnesses (the Nazarites and the printed Scriptures).
Philidelphia had nothing bad that Messiah said about them... at all. They led worldwide missions, and also led Bible Societies to spread the word and/or the gospel to save millions of people from the clutches of the Jesuit Superior General (and the Roman Catholic Church as a whole).
As a refresher for Laodecia (the era we're in right now), the Nazarites here believe that they are rich in truth, and that we have need of nothing. This is false, as we are in dire need of something, which is an alternative explanation that's not the false futuristic or preteristic explanations of the book of Revelation. We are blinded by the Jesuits, as they have decieved us (we let them do this, by the way) with false prophecy explanations among other deceptions.
Layer 3: Seals, Trumpets and Bowls
The Seals, Trumpets and Bowls are the judgements against the Roman Beast Kingdom. To keep things short, every single Seal was fulfilled, 6 of the Trumpets were fulfilled, and 5 of the Bowls were fulfilled. We're in the 6th Bowl, waiting for a global economic collapse and WW III. Once these occur, then do we go into the 7th Bowl judgement against the Roman Catholic Church and the Jesuit Order (the New World Order).
One quick thing I'll mention is that when I talk about the two witnesses here, one of them is the little book of Rev. 10. This points to the printed Bible, which was brought back to life thanks to the printing press. Martin Luther would measure the temple and find that the Papal Church is the apostate harlot. Rev. 14 points to the Bowls and the harvest. This harvest points to millions coming out of the Roman Catholic Church, though there are 1.3 billion Catholics... and we have a long way to go in getting them out of her, My people.
Remember when I talked about the Khazars earlier in this article? They are the Kings of the East that Yeshua pointed to in the 6th Bowl. The Ottoman Empire is the Euphrates River here, and it's dried up in 1922, only with Turkey remaining. Gog is already dead, as that's Lord Rothschild. Magog points to the Kings of the East. 2 of the 3 spirits have already been fulfilled (these are World Wars I and II).
Now, let me quickly point out the fact we're in the kingdom of Iron and Clay. The Iron points to the Roman Bishops, and the Clay is Islam. However, furutists will tell me I'm an idiot, and that the Iron and Clay mixture is transhumanism. This was proven to be false, as the 5th Trumpet was the rise of the Clay (Islam). The Catholics, however, wrote the Qur'an and proped up Mohhamed as their prophet. ISIS and Al Qaeda are controlled by the Jesuit Order, which is why they do what they do as terrorists... for they are Wahhabi Muslims (in other words, Mizrahi Khazars who are also Jesuits, claiming to be Arabs, when they're not).
Islam is designed to prevent Arabs from having a relationship with Messiah, which makes me really sad. Muslims will be used to kill Christians and Jews in WW III and force us into the New World Order, which will backfire on the Jesuits and Roman Bishops.
Layer 4: The Harlot Church
Rev 17:10 talks about 7 forms of government. Five had fallen by the time Revelation was written, the 6th (the Roman Emperors) fell in 476, and the 7th lead for a short space until 538.
The 8th head is the Pope, who rose to power out of the Roman Empire. Look up what the priests in the Catholic Church wear, and what they use. Does that sound familiar when you read Revelation? If it does, that's exactly the description of the Sea Beast, and how his priests dress and do their rituals.
Then comes the Black Pope. He empowers and enriches the kings of the earth, as they were used by Lucifer to carry out the Bowl judgements, and will carry out the New World Order, caugins themselves and the Roman Cathoic Church to be judged big time. This we are waiting for.
Conclusion
Hopefully this long read helps you see where I'm coming from, and I pray it helps you to start testing the scriptures against what I've said, and what Wilcoxson had said. If it is proven in your heart that you were fooled, you're on the right path in my opnion. I may be wrong, but this is where I stand.

Senator Hagerty’s Vision Beyond The GENIUS Act: Make Tennessee A Hub For Bitcoin MiningSenator Bill Hagerty (R-TN) has been in the headlines as of late as the GENIUS Act (S. 1582), a bill for which he was the primary sponsor, moves closer to passing in the U.S. Senate.
The GENIUS Act is a bill that, if enacted into law, would create a federal regulatory framework for stablecoins so that the technology can be more widely adopted. (While some Bitcoin enthusiasts may not like this, they should still pay attention to the language in the bill, as it could have an impact on U.S. citizens’ ability to use Bitcoin wallets privately.)
However, stablecoins aren’t the only thing on Senator Hagerty’s mind.
He’s also thinking about how to best produce and harness energy in Tennessee to use it for Bitcoin mining and AI compute.
He shared his vision on this topic with me in an interview I conducted with him at Bitcoin 2025:
Tennessee As A Hub For Bitcoin Mining and AI Compute
“We have an opportunity before us to be in the very lead,” Senator Hagerty told Bitcoin Magazine in regard to building nuclear facilities that can be used to produce energy for Bitcoin mining and AI processing.
“The largest utility in the world is the Tennessee Valley Authority — certainly the largest one in America — and I think we’ve got a unique opportunity here to move forward and become the energy hub of America,” he added.
“[We should] see more and more not only mining operations, but if you think about what Elon Musk is doing in Memphis with xAI, the data centers, the opportunities with artificial intelligence — there are many, many things that are going to happen in Tennessee.”
The Senator added that he believes the state can also strike partnerships with Oak Ridge National Laboratory, Vanderbilt University, the University of Tennessee and Tennessee Tech as it works to become a more friendly destination for Bitcoin miners and data centers.
“We’ve got great opportunities [from] Memphis all the way across the state,” said Senator Hagerty.
Hagerty’s Call For Bipartisanship
Whether it’s working toward stablecoin legislation or crafting regulation that will enable industries like Bitcoin mining and data centers to thrive in the United States, Senator Hagerty believes these efforts should be inherently bipartisan.
“[These are] bipartisan — or nonpartisan issue[s] — frankly,” said the Senator.
“If you care about the competitiveness of America — if you want to see innovation happen on our shores rather than being pushed overseas — then you’re going to support what we’re trying to do in terms of putting a regulatory framework in place that will deliver certainty, that will create an ecosystem here in America that will allow these companies to thrive,” he added.
“It’s not just the stablecoin legislation I’m putting forward or what may happen with Bitcoin or other technologies like that. It’s the overall blockchain technology that’s going to help advance America beyond the 21st century. We need to stay in the lead. We can stay in the lead.”

Michael Saylor and Pakistan’s Crypto Minister Bilal Talk Bitcoin and Global InvestmentPakistan’s Finance Minister Muhammad Aurangzeb and State Minister of Crypto Bilal Bin Saqib, held a conversation recently with the Executive Chairman and CEO of Strategy, Michael Saylor, about Bitcoin and its potential role in Pakistan’s economy.
BREAKING:
Pakistan’s Finance Minister and State Minister on Crypto Bilal just talked with Michael Saylor about #Bitcoin
Nation States are here
pic.twitter.com/aa5tM5kKbY
— Bitcoin Magazine (@BitcoinMagazine) June 15, 2025
Saylor highlighted the critical role of trust and leadership in attracting global capital, citing his own journey of turning a $400 million investment into a $40 billion market backed position through Bitcoin.
“Today, I will stay in touch with Bilal,” he said. “Pakistan has many brilliant people and a lot of people to do business with you. My company had less than $400 million to invest, but the markets gave me $40 billion because they trust us. And so the most important thing is leadership, intellectual leadership and that they trust you.”
Saylor further emphasized that trust and clarity of vision are what drive global capital flows.
“If the world trusts you and they hear your words, and you speak particularly, the capital and the capability will flow to Pakistan,” said Saylor. “It’s there, it wants to find a home and that’s what happened with our company. Our success is because we were clear and committed. And once the market decides who the leader is. They get behind the leader and they send their money to you. And I think they’d do it to Pakistan too. You have the most important thing, which is you have a commitment and a will and clarity here. So, I look forward to working with you.”
The new stance is a stark change for Pakistan, which had previously banned Bitcoin trading in 2018. On March 20, Bilal Bin Saqib told Bloomberg that Pakistan was planning to legalize Bitcoin and try to implement a regulatory framework to attract investors.
“Pakistan is done sitting on the sidelines,” said Saqib. “We want to attract international investment because Pakistan is a low-cost, high-growth market with 60% of the population under 30… Trump is making crypto a national priority, and every country, including Pakistan, will have to follow suit.”
During the 2025 Bitcoin Conference in Las Vegas, Saqib announced that Pakistan was creating a strategic Bitcoin reserve.
“Today, I will announce that the Pakistan government is setting up their own government led Bitcoin strategic reserve… and this wallet, the national Bitcoin wallet,” said Saqib. “It’s not for speculation or hype. We will be holding this Bitcoin and we will never ever sell them.”

- The latest firmware updates for COLDCARD devices introduce two major features: COLDCARD Co-sign (CCC) and Key Teleport between two COLDCARD Q devices using QR codes and/or NFC with a website.
What's new
- COLDCARD Co-Sign: When CCC is enabled, a second seed called the Spending Policy Key (Key C) is added to the device. This seed works with the device's Main Seed and one or more additional XPUBs (Backup Keys) to form 2-of-N multisig wallets.
- The spending policy functions like a hardware security module (HSM), enforcing rules such as magnitude and velocity limits, address whitelisting, and 2FA authentication to protect funds while maintaining flexibility and control, and is enforced each time the Spending Policy Key is used for signing.
- When spending conditions are met, the COLDCARD signs the partially signed bitcoin transaction (PSBT) with the Main Seed and Spending Policy Key for fund access. Once configured, the Spending Policy Key is required to view or change the policy, and violations are denied without explanation.
"You can override the spending policy at any time by signing with either a Backup Key and the Main Seed or two Backup Keys, depending on the number of keys (N) in the multisig."
-
A step-by-step guide for setting up CCC is available here.
-
Key Teleport for Q devices allows users to securely transfer sensitive data such as seed phrases (words, xprv), secure notes and passwords, and PSBTs for multisig. It uses QR codes or NFC, along with a helper website, to ensure reliable transmission, keeping your sensitive data protected throughout the process.
- For more technical details, see the protocol spec.
"After you sign a multisig PSBT, you have option to “Key Teleport” the PSBT file to any one of the other signers in the wallet. We already have a shared pubkey with them, so the process is simple and does not require any action on their part in advance. Plus, starting in this firmware release, COLDCARD can finalize multisig transactions, so the last signer can publish the signed transaction via PushTX (NFC tap) to get it on the blockchain directly."
- Multisig transactions are finalized when sufficiently signed. It streamlines the use of PushTX with multisig wallets.
- Signing artifacts re-export to various media. Users are now provided with the capability to export signing products, like transactions or PSBTs, to alternative media rather than the original source. For example, if a PSBT is received through a QR code, it can be signed and saved onto an SD card if needed.
- Multisig export files are signed now. Public keys are encoded as P2PKH address for all multisg signature exports. Learn more about it here.
- NFC export usability upgrade: NFC keeps exporting until CANCEL/X is pressed.
- Added Bitcoin Safe option to Export Wallet.
- 10% performance improvement in USB upload speed for large files.
- Q: Always choose the biggest possible display size for QR.
Fixes
- Do not allow change Main PIN to same value already used as Trick PIN, even if Trick PIN is hidden.
- Fix stuck progress bar under
Receiving...
after a USB communications failure. - Showing derivation path in Address Explorer for root key (m) showed double slash (//).
- Can restore developer backup with custom password other than 12 words format.
- Virtual Disk auto mode ignores already signed PSBTs (with “-signed” in file name).
- Virtual Disk auto mode stuck on “Reading…” screen sometimes.
- Finalization of foreign inputs from partial signatures. Thanks Christian Uebber!
- Temporary seed from COLDCARD backup failed to load stored multisig wallets.
Destroy Seed
also removes all Trick PINs from SE2.Lock Down Seed
requires pressing confirm key (4) to execute.- Q only: Only BBQr is allowed to export Coldcard, Core, and pretty descriptor.

2025-06-17 04:01:58The newly proposed RESTRICT ACT - is being advertised as a TikTok Ban, but is much broader than that, carries a $1M Fine and up to 20 years in prison️! It is unconstitutional and would create massive legal restrictions on the open source movement and free speech throughout the internet.
The Bill was proposed by: Senator Warner, Senator Thune, Senator Baldwin, Senator Fischer, Senator Manchin, Senator Moran, Senator Bennet, Senator Sullivan, Senator Gillibrand, Senator Collins, Senator Heinrich, and Senator Romney. It has broad support across Senators of both parties.
Corrupt politicians will not protect us. They are part of the problem. We must build, support, and learn how to use censorship resistant tools in order to defend our natural rights.
The RESTRICT Act, introduced by Senators Warner and Thune, aims to block or disrupt transactions and financial holdings involving foreign adversaries that pose risks to national security. Although the primary targets of this legislation are companies like Tik-Tok, the language of the bill could potentially be used to block or disrupt cryptocurrency transactions and, in extreme cases, block Americans’ access to open source tools or protocols like Bitcoin.
The Act creates a redundant regime paralleling OFAC without clear justification, it significantly limits the ability for injured parties to challenge actions raising due process concerns, and unlike OFAC it lacks any carve-out for protected speech. COINCENTER ON THE RESTRICT ACT

2025-06-17 18:02:14A história do Bitcoin é pontuada por marcos simbólicos que representam não apenas a evolução técnica da moeda digital, mas também sua trajetória rumo à legitimidade econômica e política. Neste artigo, revisitamos alguns dos momentos mais emblemáticos que marcaram a adoção do Bitcoin, desde seu uso inicial em uma simples transação até o seu reconhecimento como moeda oficial por nações soberanas.
A pizza mais cara da história
Em 22 de maio de 2010, Laszlo Hanyecz fez história ao pagar 10.000 BTC por duas pizzas. Na época, essa quantia equivalia a cerca de 40 dólares. Hoje, essas mesmas moedas valeriam centenas de milhões de dólares, tornando essa a refeição mais cara já registrada. Mais do que uma curiosidade, essa transação marcou a primeira vez em que o Bitcoin foi usado em uma troca comercial real, comprovando seu potencial como meio de pagamento.
Silk Road e o lado obscuro da adoção inicial
Ainda que controverso, o uso do Bitcoin no marketplace Silk Road mostrou ao mundo que a moeda digital era funcional como meio de troca em larga escala. A plataforma operou entre 2011 e 2013 e foi um catalisador para o desenvolvimento de infraestrutura em torno do BTC, apesar dos impactos negativos na imagem da criptomoeda.
Mt. Gox e a primeira grande crise
Em 2014, a corretora Mt. Gox, responsável por cerca de 70% das transações de Bitcoin no mundo, declarou falência após perder cerca de 850 mil BTC. O escândalo abalou a confiança no ecossistema, mas também deu início a um movimento de amadurecimento: a busca por melhores práticas de segurança, regulação e profissionalização do setor.
El Salvador e o reconhecimento oficial
Em setembro de 2021, El Salvador tornou-se o primeiro país a reconhecer o Bitcoin como moeda de curso legal. A medida, defendida pelo presidente Nayib Bukele, foi recebida com entusiasmo por entusiastas e com ceticismo por instituições financeiras internacionais. O experimento salvadorenho colocou o Bitcoin no centro do debate geopolítico e abriu precedentes para outras nações considerarem o mesmo caminho.
Resumindo, cada um desses momentos representa uma etapa distinta na evolução do Bitcoin: da experimentação à adoção institucional. Ao revisitarmos esses casos emblemáticos, conseguimos entender não apenas como o Bitcoin evoluiu tecnicamente, mas também como sua narrativa se consolidou como parte da história financeira contemporânea. Se a compra da pizza simbolizou o nascimento prático do BTC, o reconhecimento oficial por nações inteiras sugere um futuro em que a moeda digital pode ser protagonista em novas formas de organização econômica global.
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!

2025-06-17 16:40:16“The future is there... staring back at us. Trying to make sense of the fiction we will have become.” — William Gibson.
This month is the 4th anniversary of kycnot.me. Thank you for being here.
Fifteen years ago, Satoshi Nakamoto introduced Bitcoin, a peer-to-peer electronic cash system: a decentralized currency free from government and institutional control. Nakamoto's whitepaper showed a vision for a financial system based on trustless transactions, secured by cryptography. Some time forward and KYC (Know Your Customer), AML (Anti-Money Laundering), and CTF (Counter-Terrorism Financing) regulations started to come into play.
What a paradox: to engage with a system designed for decentralization, privacy, and independence, we are forced to give away our personal details. Using Bitcoin in the economy requires revealing your identity, not just to the party you interact with, but also to third parties who must track and report the interaction. You are forced to give sensitive data to entities you don't, can't, and shouldn't trust. Information can never be kept 100% safe; there's always a risk. Information is power, who knows about you has control over you.
Information asymmetry creates imbalances of power. When entities have detailed knowledge about individuals, they can manipulate, influence, or exploit this information to their advantage. The accumulation of personal data by corporations and governments enables extensive surveillances.
Such practices, moreover, exclude individuals from traditional economic systems if their documentation doesn't meet arbitrary standards, reinforcing a dystopian divide. Small businesses are similarly burdened by the costs of implementing these regulations, hindering free market competition^1:
How will they keep this information safe? Why do they need my identity? Why do they force businesses to enforce such regulations? It's always for your safety, to protect you from the "bad". Your life is perpetually in danger: terrorists, money launderers, villains... so the government steps in to save us.
‟Hush now, baby, baby, don't you cry Mamma's gonna make all of your nightmares come true Mamma's gonna put all of her fears into you Mamma's gonna keep you right here, under her wing She won't let you fly, but she might let you sing Mamma's gonna keep baby cosy and warm” — Mother, Pink Floyd
We must resist any attack on our privacy and freedom. To do this, we must collaborate.
If you have a service, refuse to ask for KYC; find a way. Accept cryptocurrencies like Bitcoin and Monero. Commit to circular economies. Remove the need to go through the FIAT system. People need fiat money to use most services, but we can change that.
If you're a user, donate to and prefer using services that accept such currencies. Encourage your friends to accept cryptocurrencies as well. Boycott FIAT system to the greatest extent you possibly can.
This may sound utopian, but it can be achieved. This movement can't be stopped. Go kick the hornet's nest.
“We must defend our own privacy if we expect to have any. We must come together and create systems which allow anonymous transactions to take place. People have been defending their own privacy for centuries with whispers, darkness, envelopes, closed doors, secret handshakes, and couriers. The technologies of the past did not allow for strong privacy, but electronic technologies do.” — Eric Hughes, A Cypherpunk's Manifesto
The anniversary
Four years ago, I began exploring ways to use crypto without KYC. I bookmarked a few favorite services and thought sharing them to the world might be useful. That was the first version of kycnot.me — a simple list of about 15 services. Since then, I've added services, rewritten it three times, and improved it to what it is now.
kycnot.me has remained 100% independent and 100% open source^2 all these years. I've received offers to buy the site, all of which I have declined and will continue to decline. It has been DDoS attacked many times, but we made it through. I have also rewritten the whole site almost once per year (three times in four years).
The code and scoring algorithm are open source (contributions are welcome) and I can't arbitrarly change a service's score without adding or removing attributes, making any arbitrary alterations obvious if they were fake. You can even see the score summary for any service's score.
I'm a one-person team, dedicating my free time to this project. I hope to keep doing so for many more years. Again, thank you for being part of this.

Trump Media Files to Launch Bitcoin and Ethereum ETFTrump Media & Technology Group has filed a registration statement with the U.S. Securities and Exchange Commission to launch the Truth Social Bitcoin and Ethereum ETF, B.T.
The ETF will directly hold Bitcoin and Ether, with an initial allocation of 75% Bitcoin and 25% Ether. Shares of the fund will be offered to investors to track the performance of these assets and are expected to trade on NYSE Arca once approved.
JUST IN:
Registration statement for Trump Media's Bitcoin Treasury deal was declared effective by the SEC
pic.twitter.com/PFyy44qXxH
— Bitcoin Magazine (@BitcoinMagazine) June 13, 2025
Crypto.com has been selected as the exclusive custodian, prime execution agent, staking, and liquidity provider for the ETF. Yorkville America Digital, LLC is the sponsor of the fund.
According to the company’s announcement, “The launch of the Truth Social Bitcoin and Ethereum ETF is pending effectiveness of the Registration Statement as well as approval of a Form 19b-4 filing with the SEC.”
The fund is structured as a Nevada business trust. Shares will be issued and redeemed in blocks of 10,000 by authorized participants, with cash used for creation and redemption. The ETF may offer in-kind transactions in the future, pending additional regulatory approval.
Trump Media acknowledged, “A registration statement relating to the Shares has been filed with the SEC but has not yet become effective. The Shares may not be sold, nor may offers to buy be accepted, prior to the time the registration statement becomes effective.”
The ETF is not registered under the Investment Company Act of 1940, which typically governs mutual funds and traditional ETFs by imposing rules on investor protections, disclosures, and fund operations. Because the ETF holds Bitcoin and Ether directly rather than securities, it qualifies as a grantor trust and is exempt from these requirements.
The ETF filing also reflects Trump Media’s strategy to establish a presence in the digital asset space beyond social media and streaming. With the development of its financial services arm, Truth.Fi, the company is clearly positioning itself to compete in the growing digital asset space.
If approved, the Truth Social ETF would give investors a direct, regulated path into both Bitcoin and Ether through one fund. As Trump Media expands its presence in financial services, the move signals a clear intention to compete in the space.

2025-06-17 16:40:13After almost 3 months of work, we've completed the redesign of kycnot.me. More modern and with many new features.
Privacy remains the foundation - everything still works with JavaScript disabled. If you enable JS, you will get some nice-to-have features like lazy loading and smoother page transitions, but nothing essential requires it.
User Accounts
We've introduced user accounts that require zero personal information:
- Secret user tokens - no email, no phone number, no personal data
- Randomly generated usernames for default privacy and fairness
- Karma system that rewards contributions and unlocks features: custom display names, profile pictures, and more.
Reviews and Community Discussions
On the previous sites, I was using third party open source tools for the comments and discussions. This time, I've built my own from scratch, fully integrated into the site, without JavaScript requirements.
Everyone can share their experiences and help others make informed decisions:
- Ratings: Comments can have a 1-5 star rating attached. You can have one rating per service and it will affect the overall user score.
- Discussions: These are normal comments, you can add them on any listed service.
Comment Moderation
I was strugling to keep up with moderation on the old site. For this, we've implemented an AI-powered moderation system that:
- Auto-approves legitimate comments instantly
- Flags suspicious content for human review
- Keeps discussions valuable by minimizing spam
The AI still can mark comments for human review, but most comments will get approved automatically by this system. The AI also makes summaries of the comments to help you understand the overall sentiment of the community.
Powerful Search & Filtering
Finding exactly what you need is now easier:
- Advanced filtering system with many parameters. You can even filter by attributes to pinpoint services with specific features.
The results are dynamic and shuffle services with identical scores for fairness.
See all listings
Listings are now added as 'Community Contributed' by default. This means that you can still find them in the search results, but they will be clearly marked as such.
Updated Scoring System
New dual-score approach provides more nuanced service evaluations:
- Privacy Score: Measures how well a service protects your personal information and data
-
Trust Score: Assesses reliability, security, and overall reputation
-
Combined into a weighted Overall Score for quick comparisons
- Completely transparent and open source calculation algorithm. No manual tweaking or hidden factors.
AI-Powered Terms of Service Analysis
Basically, a TLDR summary for Terms of Service:
- Automated system extracts the most important points from complex ToS documents
- Clear summaries
- Updated monthly to catch any changes
The ToS document is hashed and only will be updated if there are any changes.
Service Events and Timelines
Track the complete history of any service, on each service page you can see the timeline of events. There are two types of events:
- Automatic events: Created by the system whenever something about a service changes, like its description, supported currencies, attributes, verification status…
- Manual events: Added by admins when there’s important news, such as a service going offline, being hacked, acquired, shut down, or other major updates.
There is also a global timeline view available at /events
Notification System
Since we now have user accounts, we built a notifiaction system so you can stay informed about anything:
- Notifications for comment replies and status changes
- Watch any comment to get notified for new replies.

Os princípios básicos da criptografia.
Quando Júlio César enviou mensagens aos seus generais, ele não confiou nos seus mensageiros. Então ele substituiu cada A em suas mensagens por um D, cada B por um E, e assim por diante através do alfabeto. Somente alguém que conhecesse a regra “shift by 3” poderia decifrar suas mensagens. E assim começamos.
Criptografia e descriptografia.
Os dados que podem ser lidos e compreendidos sem quaisquer medidas especiais são chamados de texto simples ou texto não criptografado. O método de disfarçar o texto simples de forma a ocultar sua substância é chamado de criptografia. Criptografar texto simples resulta em um jargão ilegível chamado texto cifrado. Você usa criptografia para garantir que as informações sejam ocultadas de qualquer pessoa a quem não se destinam, mesmo daqueles que podem ver os dados criptografados. O processo de reverter o texto cifrado ao texto simples original é chamado de descriptografia . A Figura 1-1 ilustra esse processo.

Figura 1-1. Criptografia e descriptografia
O que é criptografia?
Criptografia é a ciência que usa a matemática para criptografar e descriptografar dados. A criptografia permite armazenar informações confidenciais ou transmiti-las através de redes inseguras (como a Internet) para que não possam ser lidas por ninguém, exceto pelo destinatário pretendido. Embora a criptografia seja a ciência que protege os dados, a criptoanálise é a ciência que analisa e quebra a comunicação segura. A criptoanálise clássica envolve uma combinação interessante de raciocínio analítico, aplicação de ferramentas matemáticas, descoberta de padrões, paciência, determinação e sorte. Os criptoanalistas também são chamados de atacantes. A criptologia abrange tanto a criptografia quanto a criptoanálise.
Criptografia forte.
"Existem dois tipos de criptografia neste mundo: a criptografia que impedirá a sua irmã mais nova de ler os seus arquivos, e a criptografia que impedirá os principais governos de lerem os seus arquivos. Este livro é sobre o último." --Bruce Schneier, Criptografia Aplicada: Protocolos, Algoritmos e Código Fonte em C. PGP também trata deste último tipo de criptografia. A criptografia pode ser forte ou fraca, conforme explicado acima. A força criptográfica é medida no tempo e nos recursos necessários para recuperar o texto simples. O resultado de uma criptografia forte é um texto cifrado que é muito difícil de decifrar sem a posse da ferramenta de decodificação apropriada. Quão díficil? Dado todo o poder computacional e o tempo disponível de hoje – mesmo um bilhão de computadores fazendo um bilhão de verificações por segundo – não é possível decifrar o resultado de uma criptografia forte antes do fim do universo. Alguém poderia pensar, então, que uma criptografia forte resistiria muito bem até mesmo contra um criptoanalista extremamente determinado. Quem pode realmente dizer? Ninguém provou que a criptografia mais forte disponível hoje resistirá ao poder computacional de amanhã. No entanto, a criptografia forte empregada pelo PGP é a melhor disponível atualmente.
Contudo, a vigilância e o conservadorismo irão protegê-lo melhor do que as alegações de impenetrabilidade.
Como funciona a criptografia?
Um algoritmo criptográfico, ou cifra, é uma função matemática usada no processo de criptografia e descriptografia. Um algoritmo criptográfico funciona em combinação com uma chave – uma palavra, número ou frase – para criptografar o texto simples. O mesmo texto simples é criptografado em texto cifrado diferente com chaves diferentes. A segurança dos dados criptografados depende inteiramente de duas coisas: a força do algoritmo criptográfico e o sigilo da chave. Um algoritmo criptográfico, mais todas as chaves possíveis e todos os protocolos que o fazem funcionar constituem um criptossistema. PGP é um criptossistema.
Criptografia convencional.
Na criptografia convencional, também chamada de criptografia de chave secreta ou de chave simétrica , uma chave é usada tanto para criptografia quanto para descriptografia. O Data Encryption Standard (DES) é um exemplo de criptossistema convencional amplamente empregado pelo Governo Federal. A Figura 1-2 é uma ilustração do processo de criptografia convencional. https://image.nostr.build/328b73ebaff84c949df2560bbbcec4bc3b5e3a5163d5fbb2ec7c7c60488f894c.jpg
Figura 1-2. Criptografia convencional
Cifra de César.
Um exemplo extremamente simples de criptografia convencional é uma cifra de substituição. Uma cifra de substituição substitui uma informação por outra. Isso é feito com mais frequência compensando as letras do alfabeto. Dois exemplos são o Anel Decodificador Secreto do Capitão Meia-Noite, que você pode ter possuído quando era criança, e a cifra de Júlio César. Em ambos os casos, o algoritmo serve para compensar o alfabeto e a chave é o número de caracteres para compensá-lo. Por exemplo, se codificarmos a palavra "SEGREDO" usando o valor chave de César de 3, deslocaremos o alfabeto para que a terceira letra abaixo (D) comece o alfabeto. Então começando com A B C D E F G H I J K L M N O P Q R S T U V W X Y Z e deslizando tudo para cima em 3, você obtém DEFGHIJKLMNOPQRSTUVWXYZABC onde D=A, E=B, F=C e assim por diante. Usando este esquema, o texto simples, "SECRET" é criptografado como "VHFUHW". Para permitir que outra pessoa leia o texto cifrado, você diz a ela que a chave é 3. Obviamente, esta é uma criptografia extremamente fraca para os padrões atuais, mas, ei, funcionou para César e ilustra como funciona a criptografia convencional.
Gerenciamento de chaves e criptografia convencional.
A criptografia convencional tem benefícios. É muito rápido. É especialmente útil para criptografar dados que não vão a lugar nenhum. No entanto, a criptografia convencional por si só como meio de transmissão segura de dados pode ser bastante cara, simplesmente devido à dificuldade de distribuição segura de chaves. Lembre-se de um personagem do seu filme de espionagem favorito: a pessoa com uma pasta trancada e algemada ao pulso. Afinal, o que há na pasta? Provavelmente não é o código de lançamento de mísseis/fórmula de biotoxina/plano de invasão em si. É a chave que irá descriptografar os dados secretos. Para que um remetente e um destinatário se comuniquem com segurança usando criptografia convencional, eles devem chegar a um acordo sobre uma chave e mantê-la secreta entre si. Se estiverem em locais físicos diferentes, devem confiar em um mensageiro, no Bat Phone ou em algum outro meio de comunicação seguro para evitar a divulgação da chave secreta durante a transmissão. Qualquer pessoa que ouvir ou interceptar a chave em trânsito poderá posteriormente ler, modificar e falsificar todas as informações criptografadas ou autenticadas com essa chave. Do DES ao Anel Decodificador Secreto do Capitão Midnight, o problema persistente com a criptografia convencional é a distribuição de chaves: como você leva a chave ao destinatário sem que alguém a intercepte?
Criptografia de chave pública.
Os problemas de distribuição de chaves são resolvidos pela criptografia de chave pública, cujo conceito foi introduzido por Whitfield Diffie e Martin Hellman em 1975. (Há agora evidências de que o Serviço Secreto Britânico a inventou alguns anos antes de Diffie e Hellman, mas a manteve um segredo militar - e não fez nada com isso.
[JH Ellis: The Possibility of Secure Non-Secret Digital Encryption, CESG Report, January 1970]) A criptografia de chave pública é um esquema assimétrico que usa um par de chaves para criptografia: uma chave pública, que criptografa os dados, e uma chave privada ou secreta correspondente para descriptografia. Você publica sua chave pública para o mundo enquanto mantém sua chave privada em segredo. Qualquer pessoa com uma cópia da sua chave pública pode criptografar informações que somente você pode ler. Até mesmo pessoas que você nunca conheceu. É computacionalmente inviável deduzir a chave privada da chave pública. Qualquer pessoa que possua uma chave pública pode criptografar informações, mas não pode descriptografá-las. Somente a pessoa que possui a chave privada correspondente pode descriptografar as informações. https://image.nostr.build/fdb71ae7a4450a523456827bdd509b31f0250f63152cc6f4ba78df290887318b.jpg
Figura 1-3. Criptografia de chave pública O principal benefício da criptografia de chave pública é que ela permite que pessoas que não possuem nenhum acordo de segurança pré-existente troquem mensagens com segurança. A necessidade de remetente e destinatário compartilharem chaves secretas através de algum canal seguro é eliminada; todas as comunicações envolvem apenas chaves públicas e nenhuma chave privada é transmitida ou compartilhada. Alguns exemplos de criptossistemas de chave pública são Elgamal (nomeado em homenagem a seu inventor, Taher Elgamal), RSA (nomeado em homenagem a seus inventores, Ron Rivest, Adi Shamir e Leonard Adleman), Diffie-Hellman (nomeado, você adivinhou, em homenagem a seus inventores). ) e DSA, o algoritmo de assinatura digital (inventado por David Kravitz). Como a criptografia convencional já foi o único meio disponível para transmitir informações secretas, o custo dos canais seguros e da distribuição de chaves relegou a sua utilização apenas àqueles que podiam pagar, como governos e grandes bancos (ou crianças pequenas com anéis descodificadores secretos). A criptografia de chave pública é a revolução tecnológica que fornece criptografia forte para as massas adultas. Lembra do mensageiro com a pasta trancada e algemada ao pulso? A criptografia de chave pública o tira do mercado (provavelmente para seu alívio).
Como funciona o PGP.
O PGP combina alguns dos melhores recursos da criptografia convencional e de chave pública. PGP é um criptossistema híbrido. Quando um usuário criptografa texto simples com PGP, o PGP primeiro compacta o texto simples. A compactação de dados economiza tempo de transmissão do modem e espaço em disco e, mais importante ainda, fortalece a segurança criptográfica. A maioria das técnicas de criptoanálise explora padrões encontrados no texto simples para quebrar a cifra. A compressão reduz esses padrões no texto simples, aumentando assim enormemente a resistência à criptoanálise. (Arquivos que são muito curtos para compactar ou que não são compactados bem não são compactados.) O PGP então cria uma chave de sessão, que é uma chave secreta única. Esta chave é um número aleatório gerado a partir dos movimentos aleatórios do mouse e das teclas digitadas. Esta chave de sessão funciona com um algoritmo de criptografia convencional rápido e muito seguro para criptografar o texto simples; o resultado é texto cifrado. Depois que os dados são criptografados, a chave da sessão é criptografada na chave pública do destinatário. Essa chave de sessão criptografada com chave pública é transmitida junto com o texto cifrado ao destinatário.
Figura 1-4. Como funciona a criptografia PGP A descriptografia funciona ao contrário. A cópia do PGP do destinatário usa sua chave privada para recuperar a chave de sessão temporária, que o PGP usa para descriptografar o texto cifrado criptografado convencionalmente.
Figura 1-5. Como funciona a descriptografia PGP A combinação dos dois métodos de criptografia combina a conveniência da criptografia de chave pública com a velocidade da criptografia convencional. A criptografia convencional é cerca de 1.000 vezes mais rápida que a criptografia de chave pública. A criptografia de chave pública, por sua vez, fornece uma solução para
problemas de distribuição de chaves e transmissão de dados. Usados em conjunto, o desempenho e a distribuição de chaves são melhorados sem qualquer sacrifício na segurança.
Chaves.
Uma chave é um valor que funciona com um algoritmo criptográfico para produzir um texto cifrado específico. As chaves são basicamente números muito, muito, muito grandes. O tamanho da chave é medido em bits; o número que representa uma chave de 1024 bits é enorme. Na criptografia de chave pública, quanto maior a chave, mais seguro é o texto cifrado. No entanto, o tamanho da chave pública e o tamanho da chave secreta da criptografia convencional não têm nenhuma relação. Uma chave convencional de 80 bits tem a força equivalente a uma chave pública de 1.024 bits. Uma chave convencional de 128 bits é equivalente a uma chave pública de 3.000 bits. Novamente, quanto maior a chave, mais segura, mas os algoritmos usados para cada tipo de criptografia são muito diferentes e, portanto, a comparação é como a de maçãs com laranjas. Embora as chaves pública e privada estejam matematicamente relacionadas, é muito difícil derivar a chave privada dada apenas a chave pública; no entanto, derivar a chave privada é sempre possível, desde que haja tempo e capacidade computacional suficientes. Isto torna muito importante escolher chaves do tamanho certo; grande o suficiente para ser seguro, mas pequeno o suficiente para ser aplicado rapidamente. Além disso, você precisa considerar quem pode estar tentando ler seus arquivos, quão determinados eles estão, quanto tempo têm e quais podem ser seus recursos. Chaves maiores serão criptograficamente seguras por um longo período de tempo. Se o que você deseja criptografar precisar ficar oculto por muitos anos, você pode usar uma chave muito grande. Claro, quem sabe quanto tempo levará para determinar sua chave usando os computadores mais rápidos e eficientes de amanhã? Houve um tempo em que uma chave simétrica de 56 bits era considerada extremamente segura. As chaves são armazenadas de forma criptografada. O PGP armazena as chaves em dois arquivos no seu disco rígido; um para chaves públicas e outro para chaves privadas. Esses arquivos são chamados de chaveiros. Ao usar o PGP, você normalmente adicionará as chaves públicas dos seus destinatários ao seu chaveiro público. Suas chaves privadas são armazenadas em seu chaveiro privado. Se você perder seu chaveiro privado, não será possível descriptografar nenhuma informação criptografada nas chaves desse anel.
Assinaturas digitais.
Um grande benefício da criptografia de chave pública é que ela fornece um método para empregar assinaturas digitais. As assinaturas digitais permitem ao destinatário da informação verificar a autenticidade da origem da informação e também verificar se a informação está intacta. Assim, as assinaturas digitais de chave pública fornecem autenticação e integridade de dados. A assinatura digital também proporciona o não repúdio, o que significa que evita que o remetente alegue que não enviou realmente as informações. Esses recursos são tão fundamentais para a criptografia quanto a privacidade, se não mais. Uma assinatura digital tem a mesma finalidade de uma assinatura manuscrita. No entanto, uma assinatura manuscrita é fácil de falsificar. Uma assinatura digital é superior a uma assinatura manuscrita porque é quase impossível de ser falsificada, além de atestar o conteúdo da informação, bem como a identidade do signatário.
Algumas pessoas tendem a usar mais assinaturas do que criptografia. Por exemplo, você pode não se importar se alguém souber que você acabou de depositar US$ 1.000 em sua conta, mas quer ter certeza de que foi o caixa do banco com quem você estava lidando. A maneira básica pela qual as assinaturas digitais são criadas é ilustrada na Figura 1-6 . Em vez de criptografar informações usando a chave pública de outra pessoa, você as criptografa com sua chave privada. Se as informações puderem ser descriptografadas com sua chave pública, elas deverão ter se originado em você.
Figura 1-6. Assinaturas digitais simples
Funções hash.
O sistema descrito acima apresenta alguns problemas. É lento e produz um enorme volume de dados – pelo menos o dobro do tamanho da informação original. Uma melhoria no esquema acima é a adição de uma função hash unidirecional no processo. Uma função hash unidirecional recebe uma entrada de comprimento variável – neste caso, uma mensagem de qualquer comprimento, até mesmo milhares ou milhões de bits – e produz uma saída de comprimento fixo; digamos, 160 bits. A função hash garante que, se a informação for alterada de alguma forma – mesmo que por apenas um bit – seja produzido um valor de saída totalmente diferente. O PGP usa uma função hash criptograficamente forte no texto simples que o usuário está assinando. Isso gera um item de dados de comprimento fixo conhecido como resumo da mensagem. (Novamente, qualquer alteração nas informações resulta em um resumo totalmente diferente.) Então o PGP usa o resumo e a chave privada para criar a “assinatura”. O PGP transmite a assinatura e o texto simples juntos. Ao receber a mensagem, o destinatário utiliza o PGP para recalcular o resumo, verificando assim a assinatura. O PGP pode criptografar o texto simples ou não; assinar texto simples é útil se alguns dos destinatários não estiverem interessados ou não forem capazes de verificar a assinatura. Desde que uma função hash segura seja usada, não há como retirar a assinatura de alguém de um documento e anexá-la a outro, ou alterar uma mensagem assinada de qualquer forma. A menor alteração em um documento assinado causará falha no processo de verificação da assinatura digital.
Figura 1-7. Assinaturas digitais seguras As assinaturas digitais desempenham um papel importante na autenticação e validação de chaves de outros usuários PGP.
Certificados digitais.
Um problema com os criptosistemas de chave pública é que os usuários devem estar constantemente vigilantes para garantir que estão criptografando com a chave da pessoa correta. Num ambiente onde é seguro trocar chaves livremente através de servidores públicos, os ataques man-in-the-middle são uma ameaça potencial. Neste tipo de ataque, alguém publica uma chave falsa com o nome e ID de usuário do destinatário pretendido. Os dados criptografados – e interceptados por – o verdadeiro proprietário desta chave falsa estão agora em mãos erradas. Em um ambiente de chave pública, é vital que você tenha certeza de que a chave pública para a qual você está criptografando os dados é de fato a chave pública do destinatário pretendido e não uma falsificação. Você pode simplesmente criptografar apenas as chaves que foram entregues fisicamente a você. Mas suponha que você precise trocar informações com pessoas que nunca conheceu; como você pode saber se tem a chave correta? Os certificados digitais, ou certs, simplificam a tarefa de estabelecer se uma chave pública realmente pertence ao suposto proprietário. Um certificado é uma forma de credencial. Exemplos podem ser sua carteira de motorista, seu cartão de previdência social ou sua certidão de nascimento. Cada um deles contém algumas informações que identificam você e alguma autorização informando que outra pessoa confirmou sua identidade. Alguns certificados, como o seu passaporte, são uma confirmação importante o suficiente da sua identidade para que você não queira perdê-los, para que ninguém os use para se passar por você.
Um certificado digital são dados que funcionam como um certificado físico. Um certificado digital é uma informação incluída na chave pública de uma pessoa que ajuda outras pessoas a verificar se uma chave é genuína ou válida. Os certificados digitais são usados para impedir tentativas de substituir a chave de uma pessoa por outra.
Um certificado digital consiste em três coisas:
● Uma chave pública.
● Informações do certificado. (Informações de "identidade" sobre o usuário, como nome, ID do usuário e assim por diante.) ● Uma ou mais assinaturas digitais.
O objetivo da assinatura digital em um certificado é afirmar que as informações do certificado foram atestadas por alguma outra pessoa ou entidade. A assinatura digital não atesta a autenticidade do certificado como um todo; ele atesta apenas que as informações de identidade assinadas acompanham ou estão vinculadas à chave pública. Assim, um certificado é basicamente uma chave pública com uma ou duas formas de identificação anexadas, além de um forte selo de aprovação de algum outro indivíduo confiável.
Figura 1-8. Anatomia de um certificado PGP
Distribuição de certificados.
Os certificados são utilizados quando é necessário trocar chaves públicas com outra pessoa. Para pequenos grupos de pessoas que desejam se comunicar com segurança, é fácil trocar manualmente disquetes ou e-mails contendo a chave pública de cada proprietário. Esta é a distribuição manual de chave pública e é prática apenas até certo ponto. Além desse ponto, é necessário implementar sistemas que possam fornecer os mecanismos necessários de segurança, armazenamento e troca para que colegas de trabalho, parceiros de negócios ou estranhos possam se comunicar, se necessário. Eles podem vir na forma de repositórios somente de armazenamento, chamados Servidores de Certificados, ou sistemas mais estruturados que fornecem recursos adicionais de gerenciamento de chaves e são chamados de Infraestruturas de Chave Pública (PKIs).
Servidores de certificados.
Um servidor de certificados, também chamado de servidor certificado ou servidor de chaves, é um banco de dados que permite aos usuários enviar e recuperar certificados digitais. Um servidor certificado geralmente fornece alguns recursos administrativos que permitem que uma empresa mantenha suas políticas de segurança – por exemplo, permitindo que apenas as chaves que atendam a determinados requisitos sejam armazenadas.
Infraestruturas de Chave Pública.
Uma PKI contém os recursos de armazenamento de certificados de um servidor de certificados, mas também fornece recursos de gerenciamento de certificados (a capacidade de emitir, revogar, armazenar, recuperar e confiar em certificados). A principal característica de uma PKI é a introdução do que é conhecido como Autoridade Certificadora,ou CA, que é uma entidade humana — uma pessoa, grupo, departamento, empresa ou outra associação — que uma organização autorizou a emitir certificados para seus usuários de computador. (A função de uma CA é análoga à do Passport Office do governo de um país.) Uma CA cria certificados e os assina digitalmente usando a chave privada da CA. Devido ao seu papel na criação de certificados, a CA é o componente central de uma PKI. Usando a chave pública da CA, qualquer pessoa que queira verificar a autenticidade de um certificado verifica a assinatura digital da CA emissora e, portanto, a integridade do conteúdo do certificado (mais importante ainda, a chave pública e a identidade do titular do certificado).
Formatos de certificado.
Um certificado digital é basicamente uma coleção de informações de identificação vinculadas a uma chave pública e assinadas por um terceiro confiável para provar sua autenticidade. Um certificado digital pode ter vários formatos diferentes.
O PGP reconhece dois formatos de certificado diferentes:
● Certificados PGP ● Certificados X.509 Formato do certificado PGP. Um certificado PGP inclui (mas não está limitado a) as seguintes informações: ● O número da versão do PGP — identifica qual versão do PGP foi usada para criar a chave associada ao certificado. A chave pública do titular do certificado — a parte pública do seu par de chaves, juntamente com o algoritmo da chave: RSA, DH (Diffie-Hellman) ou DSA (Algoritmo de Assinatura Digital).
● As informações do detentor do certificado — consistem em informações de “identidade” sobre o usuário, como seu nome, ID de usuário, fotografia e assim por diante. ● A assinatura digital do proprietário do certificado — também chamada de autoassinatura, é a assinatura que utiliza a chave privada correspondente da chave pública associada ao certificado. ● O período de validade do certificado — a data/hora de início e a data/hora de expiração do certificado; indica quando o certificado irá expirar. ● O algoritmo de criptografia simétrica preferido para a chave — indica o algoritmo de criptografia para o qual o proprietário do certificado prefere que as informações sejam criptografadas. Os algoritmos suportados são CAST, IDEA ou Triple-DES. Você pode pensar em um certificado PGP como uma chave pública com um ou mais rótulos vinculados a ele (veja a Figura 1.9 ). Nessas 'etiquetas' você encontrará informações que identificam o proprietário da chave e uma assinatura do proprietário da chave, que afirma que a chave e a identificação andam juntas. (Essa assinatura específica é chamada de autoassinatura; todo certificado PGP contém uma autoassinatura.) Um aspecto único do formato de certificado PGP é que um único certificado pode conter múltiplas assinaturas. Várias ou muitas pessoas podem assinar o par chave/identificação para atestar a sua própria garantia de que a chave pública pertence definitivamente ao proprietário especificado. Se você procurar em um servidor de certificados público, poderá notar que certos certificados, como o do criador do PGP, Phil Zimmermann, contêm muitas assinaturas. Alguns certificados PGP consistem em uma chave pública com vários rótulos, cada um contendo um meio diferente de identificar o proprietário da chave (por exemplo, o nome do proprietário e a conta de e-mail corporativa, o apelido do proprietário e a conta de e-mail residencial, uma fotografia do proprietário — tudo em um certificado). A lista de assinaturas de cada uma dessas identidades pode ser diferente; as assinaturas atestam a autenticidade de que um dos rótulos pertence à chave pública, e não que todos os rótulos da chave sejam autênticos. (Observe que 'autêntico' está nos olhos de quem vê - assinaturas são opiniões, e diferentes pessoas dedicam diferentes níveis de devida diligência na verificação da autenticidade antes de assinar uma chave.)
Figura 1-9. Um certificado PGP
Formato de certificado X.509.
X.509 é outro formato de certificado muito comum. Todos os certificados X.509 estão em conformidade com o padrão internacional ITU-T X.509; assim (teoricamente) os certificados X.509 criados para um aplicativo podem ser usados por qualquer aplicativo compatível com X.509. Na prática, porém, diferentes empresas criaram suas próprias extensões para certificados X.509, e nem todas funcionam juntas. Um certificado exige que alguém valide que uma chave pública e o nome do proprietário da chave andam juntos. Com os certificados PGP, qualquer pessoa pode desempenhar o papel de validador. Com certificados X.509, o validador é sempre uma Autoridade Certificadora ou alguém designado por uma CA. (Tenha em mente que os certificados PGP também suportam totalmente uma estrutura hierárquica usando uma CA para validar certificados.)
Um certificado X.509 é uma coleção de um conjunto padrão de campos contendo informações sobre um usuário ou dispositivo e sua chave pública correspondente. O padrão X.509 define quais informações vão para o certificado e descreve como codificá-lo (o formato dos dados). Todos os certificados X.509 possuem os seguintes dados:
O número da versão X.509
— identifica qual versão do padrão X.509 se aplica a este certificado, o que afeta quais informações podem ser especificadas nele. A mais atual é a versão 3.
A chave pública do titular do certificado
— a chave pública do titular do certificado, juntamente com um identificador de algoritmo que especifica a qual sistema criptográfico a chave pertence e quaisquer parâmetros de chave associados.
O número de série do certificado
— a entidade (aplicação ou pessoa) que criou o certificado é responsável por atribuir-lhe um número de série único para distingui-lo de outros certificados que emite. Esta informação é usada de diversas maneiras; por exemplo, quando um certificado é revogado, seu número de série é colocado em uma Lista de Revogação de Certificados ou CRL.
O identificador exclusivo do detentor do certificado
— (ou DN — nome distinto). Este nome pretende ser exclusivo na Internet. Este nome pretende ser exclusivo na Internet. Um DN consiste em múltiplas subseções e pode ser parecido com isto: CN=Bob Allen, OU=Divisão Total de Segurança de Rede, O=Network Associates, Inc., C=EUA (Referem-se ao nome comum, à unidade organizacional, à organização e ao país do sujeito .)
O período de validade do certificado
— a data/hora de início e a data/hora de expiração do certificado; indica quando o certificado irá expirar.
O nome exclusivo do emissor do certificado
— o nome exclusivo da entidade que assinou o certificado. Normalmente é uma CA. A utilização do certificado implica confiar na entidade que assinou este certificado. (Observe que em alguns casos, como certificados de CA raiz ou de nível superior , o emissor assina seu próprio certificado.)
A assinatura digital do emitente
— a assinatura utilizando a chave privada da entidade que emitiu o certificado.
O identificador do algoritmo de assinatura
— identifica o algoritmo usado pela CA para assinar o certificado.
Existem muitas diferenças entre um certificado X.509 e um certificado PGP, mas as mais importantes são as seguintes: você pode criar seu próprio certificado PGP;
● você deve solicitar e receber um certificado X.509 de uma autoridade de certificação
● Os certificados X.509 suportam nativamente apenas um único nome para o proprietário da chave
● Os certificados X.509 suportam apenas uma única assinatura digital para atestar a validade da chave
Para obter um certificado X.509, você deve solicitar a uma CA a emissão de um certificado. Você fornece sua chave pública, prova de que possui a chave privada correspondente e algumas informações específicas sobre você. Em seguida, você assina digitalmente as informações e envia o pacote completo – a solicitação de certificado – para a CA. A CA então realiza algumas diligências para verificar se as informações fornecidas estão corretas e, em caso afirmativo, gera o certificado e o devolve.
Você pode pensar em um certificado X.509 como um certificado de papel padrão (semelhante ao que você recebeu ao concluir uma aula de primeiros socorros básicos) com uma chave pública colada nele. Ele contém seu nome e algumas informações sobre você, além da assinatura da pessoa que o emitiu para você.
Figura 1-10. Um certificado X.509 Provavelmente, o uso mais visível dos certificados X.509 atualmente é em navegadores da web.
Validade e confiança Cada usuário em um sistema de chave pública está vulnerável a confundir uma chave falsa (certificado) com uma chave real. Validade é a confiança de que um certificado de chave pública pertence ao seu suposto proprietário. A validade é essencial em um ambiente de chave pública onde você deve estabelecer constantemente se um determinado certificado é autêntico ou não. Depois de ter certeza de que um certificado pertencente a outra pessoa é válido, você pode assinar a cópia em seu chaveiro para atestar que verificou o certificado e que ele é autêntico. Se quiser que outras pessoas saibam que você deu ao certificado seu selo de aprovação, você pode exportar a assinatura para um servidor de certificados para que outras pessoas possam vê-la.
Conforme descrito na seção Infraestruturas de Chave Pública , algumas empresas designam uma ou mais Autoridades de Certificação (CAs) para indicar a validade do certificado. Em uma organização que usa uma PKI com certificados X.509, é função da CA emitir certificados aos usuários — um processo que geralmente envolve responder à solicitação de certificado do usuário. Em uma organização que usa certificados PGP sem PKI, é função da CA verificar a autenticidade de todos os certificados PGP e depois assinar os bons. Basicamente, o objetivo principal de uma CA é vincular uma chave pública às informações de identificação contidas no certificado e, assim, garantir a terceiros que algum cuidado foi tomado para garantir que esta ligação das informações de identificação e da chave seja válida. O CA é o Grand Pooh-bah da validação em uma organização; alguém em quem todos confiam e, em algumas organizações, como aquelas que utilizam uma PKI, nenhum certificado é considerado válido, a menos que tenha sido assinado por uma CA confiável.
Verificando validade.
Uma maneira de estabelecer a validade é passar por algum processo manual. Existem várias maneiras de fazer isso. Você pode exigir que o destinatário pretendido lhe entregue fisicamente uma cópia de sua chave pública. Mas isto é muitas vezes inconveniente e ineficiente. Outra forma é verificar manualmente a impressão digital do certificado. Assim como as impressões digitais de cada ser humano são únicas, a impressão digital de cada certificado PGP é única. A impressão digital é um hash do certificado do usuário e aparece como uma das propriedades do certificado. No PGP, a impressão digital pode aparecer como um número hexadecimal ou uma série das chamadas palavras biométricas, que são foneticamente distintas e são usadas para facilitar um pouco o processo de identificação da impressão digital. Você pode verificar se um certificado é válido ligando para o proprietário da chave (para que você origine a transação) e pedindo ao proprietário que leia a impressão digital de sua chave para você e compare essa impressão digital com aquela que você acredita ser a verdadeira. Isso funciona se você conhece a voz do proprietário, mas como verificar manualmente a identidade de alguém que você não conhece? Algumas pessoas colocam a impressão digital de sua chave em seus cartões de visita exatamente por esse motivo. Outra forma de estabelecer a validade do certificado de alguém é confiar que um terceiro indivíduo passou pelo processo de validação do mesmo. Uma CA, por exemplo, é responsável por garantir que, antes de emitir um certificado, ele ou ela o verifique cuidadosamente para ter certeza de que a parte da chave pública realmente pertence ao suposto proprietário. Qualquer pessoa que confie na CA considerará automaticamente quaisquer certificados assinados pela CA como válidos. Outro aspecto da verificação da validade é garantir que o certificado não foi revogado. Para obter mais informações, consulte a seção Revogação de certificado .
Estabelecendo confiança.
Você valida certificados. Você confia nas pessoas. Mais especificamente, você confia nas pessoas para validar os certificados de outras pessoas. Normalmente, a menos que o proprietário lhe entregue o certificado, você terá que confiar na palavra de outra pessoa de que ele é válido.
Introdutores meta e confiáveis.
Na maioria das situações, as pessoas confiam completamente na CA para estabelecer a validade dos certificados. Isso significa que todos os demais dependem da CA para passar por todo o processo de validação manual. Isso é aceitável até um certo número de usuários ou locais de trabalho e, então, não é possível para a AC manter o mesmo nível de validação de qualidade. Nesse caso, é necessário adicionar outros validadores ao sistema.
Um CA também pode ser um meta- introdutor. Um meta-introdutor confere não apenas validade às chaves, mas também confere a capacidade de confiar nas chaves a outros. Semelhante ao rei que entrega seu selo a seus conselheiros de confiança para que eles possam agir de acordo com sua autoridade, o meta-introdutor permite que outros atuem como introdutores de confiança. Esses introdutores confiáveis podem validar chaves com o mesmo efeito do meta-introdutor. Eles não podem, entretanto, criar novos introdutores confiáveis.
Meta-introdutor e introdutor confiável são termos PGP. Em um ambiente X.509, o meta-introdutor é chamado de Autoridade de Certificação raiz ( CA raiz) e os introdutores confiáveis são Autoridades de Certificação subordinadas . A CA raiz usa a chave privada associada a um tipo de certificado especial denominado certificado CA raiz para assinar certificados. Qualquer certificado assinado pelo certificado CA raiz é visto como válido por qualquer outro certificado assinado pela raiz. Este processo de validação funciona mesmo para certificados assinados por outras CAs no sistema — desde que o certificado da CA raiz tenha assinado o certificado da CA subordinada, qualquer certificado assinado pela CA será considerado válido para outras pessoas dentro da hierarquia. Este processo de verificação de backup por meio do sistema para ver quem assinou cujo certificado é chamado de rastreamento de um caminho de certificação ou cadeia de certificação.
Modelos de confiança.
Em sistemas relativamente fechados, como em uma pequena empresa, é fácil rastrear um caminho de certificação até a CA raiz. No entanto, os usuários muitas vezes precisam se comunicar com pessoas fora do seu ambiente corporativo, incluindo algumas que nunca conheceram, como fornecedores, consumidores, clientes, associados e assim por diante. É difícil estabelecer uma linha de confiança com aqueles em quem sua CA não confia explicitamente. As empresas seguem um ou outro modelo de confiança, que determina como os usuários irão estabelecer a validade do certificado. Existem três modelos diferentes:
Confiança Direta.
Confiança Hierárquica Uma teia de confiança Confiança direta A confiança direta é o modelo de confiança mais simples. Neste modelo, um usuário confia que uma chave é válida porque sabe de onde ela veio. Todos os criptosistemas usam essa forma de confiança de alguma forma. Por exemplo, em navegadores da Web, as chaves raiz da Autoridade de Certificação são diretamente confiáveis porque foram enviadas pelo fabricante. Se houver alguma forma de hierarquia, ela se estenderá a partir desses certificados diretamente confiáveis. No PGP, um usuário que valida as chaves e nunca define outro certificado para ser um introdutor confiável está usando confiança direta.
Figura 1-11. Confiança direta
Confiança Hierárquica.
Em um sistema hierárquico, há vários certificados "raiz" a partir dos quais a confiança se estende. Esses certificados podem certificar eles próprios certificados ou podem certificar certificados que certificam ainda outros certificados em alguma cadeia. Considere isso como uma grande “árvore” de confiança. A validade do certificado "folha" é verificada rastreando desde seu certificador até outros certificadores, até que um certificado raiz diretamente confiável seja encontrado.
Figura 1-12. Confiança hierárquica
Teia de Confiança.
Uma teia de confiança abrange ambos os outros modelos, mas também acrescenta a noção de que a confiança está nos olhos de quem vê (que é a visão do mundo real) e a ideia de que mais informação é melhor. É, portanto, um modelo de confiança cumulativa. Um certificado pode ser confiável diretamente ou confiável em alguma cadeia que remonta a um certificado raiz diretamente confiável (o meta-introdutor) ou por algum grupo de introdutores.
Talvez você já tenha ouvido falar do termo seis graus de separação, que sugere que qualquer pessoa no mundo pode determinar algum vínculo com qualquer outra pessoa no mundo usando seis ou menos outras pessoas como intermediários. Esta é uma teia de introdutores. É também a visão de confiança do PGP. PGP usa assinaturas digitais como forma de introdução. Quando qualquer usuário assina a chave de outro, ele ou ela se torna o introdutor dessa chave. À medida que esse processo avança, ele estabelece uma rede de confiança.
Em um ambiente PGP, qualquer usuário pode atuar como autoridade certificadora. Qualquer usuário PGP pode validar o certificado de chave pública de outro usuário PGP. No entanto, tal certificado só é válido para outro usuário se a parte confiável reconhecer o validador como um introdutor confiável. (Ou seja, você confia na minha opinião de que as chaves dos outros são válidas apenas se você me considerar um apresentador confiável. Caso contrário, minha opinião sobre a validade das outras chaves é discutível.) Armazenados no chaveiro público de cada usuário estão indicadores de
● se o usuário considera ou não uma chave específica válida
● o nível de confiança que o usuário deposita na chave que o proprietário da chave pode servir como certificador das chaves de terceiros
Você indica, na sua cópia da minha chave, se acha que meu julgamento conta. Na verdade, é um sistema de reputação: certas pessoas têm a reputação de fornecer boas assinaturas e as pessoas confiam nelas para atestar a validade de outras chaves.
Níveis de confiança no PGP.
O nível mais alto de confiança em uma chave, a confiança implícita , é a confiança em seu próprio par de chaves. O PGP assume que se você possui a chave privada, você deve confiar nas ações da sua chave pública relacionada. Quaisquer chaves assinadas pela sua chave implicitamente confiável são válidas.
Existem três níveis de confiança que você pode atribuir à chave pública de outra pessoa:
● Confiança total ● Confiança marginal ● Não confiável (ou não confiável)
Para tornar as coisas confusas, também existem três níveis de validade:
● Válido ● Marginalmente válido ● Inválido
Para definir a chave de outra pessoa como um introdutor confiável, você
- Comece com uma chave válida, que seja.
- assinado por você ou
-
assinado por outro apresentador confiável e então
-
Defina o nível de confiança que você acha que o proprietário da chave tem direito.
Por exemplo, suponha que seu chaveiro contenha a chave de Alice. Você validou a chave de Alice e indica isso assinando-a. Você sabe que Alice é uma verdadeira defensora da validação de chaves de outras pessoas. Portanto, você atribui a chave dela com confiança total. Isso faz de Alice uma Autoridade Certificadora. Se Alice assinar a chave de outra pessoa, ela aparecerá como Válida em seu chaveiro. O PGP requer uma assinatura Totalmente confiável ou duas assinaturas Marginalmente confiáveis para estabelecer uma chave como válida. O método do PGP de considerar dois Marginais iguais a um Completo é semelhante a um comerciante que solicita duas formas de identificação. Você pode considerar Alice bastante confiável e também considerar Bob bastante confiável. Qualquer um deles sozinho corre o risco de assinar acidentalmente uma chave falsificada, portanto, você pode não depositar total confiança em nenhum deles. No entanto, as probabilidades de ambos os indivíduos terem assinado a mesma chave falsa são provavelmente pequenas.
Revogação de certificado.
Os certificados só são úteis enquanto são válidos. Não é seguro simplesmente presumir que um certificado é válido para sempre. Na maioria das organizações e em todas as PKIs, os certificados têm uma vida útil restrita. Isso restringe o período em que um sistema fica vulnerável caso ocorra um comprometimento do certificado.
Os certificados são assim criados com um período de validade programado: uma data/hora de início e uma data/hora de expiração. Espera-se que o certificado seja utilizável durante todo o seu período de validade (seu tempo de vida ). Quando o certificado expirar, ele não será mais válido, pois a autenticidade do seu par chave/identificação não estará mais garantida. (O certificado ainda pode ser usado com segurança para reconfirmar informações que foram criptografadas ou assinadas dentro do período de validade – no entanto, ele não deve ser confiável para tarefas criptográficas futuras.)
Existem também situações em que é necessário invalidar um certificado antes da sua data de expiração, como quando o titular do certificado termina o contrato de trabalho com a empresa ou suspeita que a chave privada correspondente do certificado foi comprometida. Isso é chamado de revogação. Um certificado revogado é muito mais suspeito do que um certificado expirado. Os certificados expirados são inutilizáveis, mas não apresentam a mesma ameaça de comprometimento que um certificado revogado. Qualquer pessoa que tenha assinado um certificado pode revogar a sua assinatura no certificado (desde que utilize a mesma chave privada que criou a assinatura). Uma assinatura revogada indica que o signatário não acredita mais que a chave pública e as informações de identificação pertencem uma à outra, ou que a chave pública do certificado (ou a chave privada correspondente) foi comprometida. Uma assinatura revogada deve ter quase tanto peso quanto um certificado revogado. Com certificados X.509, uma assinatura revogada é praticamente igual a um certificado revogado, visto que a única assinatura no certificado é aquela que o tornou válido em primeiro lugar – a assinatura da CA. Os certificados PGP fornecem o recurso adicional de que você pode revogar todo o seu certificado (não apenas as assinaturas nele) se você achar que o certificado foi comprometido. Somente o proprietário do certificado (o detentor da chave privada correspondente) ou alguém que o proprietário do certificado tenha designado como revogador pode revogar um certificado PGP. (Designar um revogador é uma prática útil, pois muitas vezes é a perda da senha da chave privada correspondente do certificado que leva um usuário PGP a revogar seu certificado - uma tarefa que só é possível se alguém tiver acesso à chave privada. ) Somente o emissor do certificado pode revogar um certificado X.509.
Comunicar que um certificado foi revogado.
Quando um certificado é revogado, é importante conscientizar os usuários potenciais do certificado de que ele não é mais válido. Com certificados PGP, a maneira mais comum de comunicar que um certificado foi revogado é publicá-lo em um servidor de certificados para que outras pessoas que desejem se comunicar com você sejam avisadas para não usar essa chave pública. Em um ambiente PKI, a comunicação de certificados revogados é mais comumente obtida por meio de uma estrutura de dados chamada Lista de Revogação de Certificados, ou CRL, que é publicada pela CA. A CRL contém uma lista validada com carimbo de data e hora de todos os certificados revogados e não expirados no sistema. Os certificados revogados permanecem na lista apenas até expirarem e, em seguida, são removidos da lista — isso evita que a lista fique muito longa. A CA distribui a CRL aos usuários em algum intervalo programado regularmente (e potencialmente fora do ciclo, sempre que um certificado é revogado). Teoricamente, isso impedirá que os usuários usem involuntariamente um certificado comprometido. É possível, no entanto, que haja um período de tempo entre as CRLs em que um certificado recentemente comprometido seja usado.
O que é uma senha?
A maioria das pessoas está familiarizada com a restrição de acesso a sistemas de computador por meio de uma senha, que é uma sequência única de caracteres que um usuário digita como código de identificação.
Uma senha longa é uma versão mais longa de uma senha e, em teoria, mais segura. Normalmente composta por várias palavras, uma frase secreta é mais segura contra ataques de dicionário padrão, em que o invasor tenta todas as palavras do dicionário na tentativa de determinar sua senha. As melhores senhas são relativamente longas e complexas e contêm uma combinação de letras maiúsculas e minúsculas, caracteres numéricos e de pontuação. O PGP usa uma senha para criptografar sua chave privada em sua máquina. Sua chave privada é criptografada em seu disco usando um hash de sua senha como chave secreta. Você usa a senha para descriptografar e usar sua chave privada. Uma senha deve ser difícil de esquecer e difícil de ser adivinhada por outras pessoas. Deve ser algo já firmemente enraizado na sua memória de longo prazo, em vez de algo que você invente do zero. Por que? Porque se você esquecer sua senha, você estará sem sorte. Sua chave privada é total e absolutamente inútil sem sua senha e nada pode ser feito a respeito. Lembra-se da citação anterior neste capítulo?
PGP é a criptografia que manterá os principais governos fora dos seus arquivos. Certamente também o manterá fora de seus arquivos. Tenha isso em mente quando decidir alterar sua senha para a piada daquela piada que você nunca consegue lembrar.
Divisão de chave.
Dizem que um segredo não é segredo se for conhecido por mais de uma pessoa. Compartilhar um par de chaves privadas representa um grande problema. Embora não seja uma prática recomendada, às vezes é necessário compartilhar um par de chaves privadas. Chaves de assinatura corporativa, por exemplo, são chaves privadas usadas por uma empresa para assinar – por exemplo – documentos legais, informações pessoais confidenciais ou comunicados de imprensa para autenticar sua origem. Nesse caso, vale a pena que vários membros da empresa tenham acesso à chave privada. No entanto, isto significa que qualquer indivíduo pode agir plenamente em nome da empresa. Nesse caso, é aconselhável dividir a chave entre várias pessoas, de modo que mais de uma ou duas pessoas apresentem um pedaço da chave para reconstituí-la em condições utilizáveis. Se poucas peças da chave estiverem disponíveis, a chave ficará inutilizável. Alguns exemplos são dividir uma chave em três partes e exigir duas delas para reconstituir a chave, ou dividi-la em duas partes e exigir ambas as peças. Se uma conexão de rede segura for usada durante o processo de reconstituição, os acionistas da chave não precisam estar fisicamente presentes para aderirem novamente à chave.

H100 Group Receives 144.8 BTC in Convertible Loan DealH100 Group, Swedish health-tech firm, has received 144.8 BTC as part of a settlement tied to its convertible loan agreement, according to a company press release issued Monday. With this latest transaction, the Stockholm-based firm now holds a total of 169.2 BTC on its balance sheet.
H100 Group Receives 144.8 BTC as Partial Settlement Under Convertible Loan Framework. Now holds 169.2 BTC. pic.twitter.com/MAW044iXkG
— H100 (@H100Group) June 16, 2025
The 144.8 BTC was transferred as a part of the first four segments of H100’s loan agreement, which has been well received by investors thus far. H100 said in the release, “H100 Group AB (‘H100 Group’ or the ‘Company’) has today received 144.8 BTC as part of the proceeds from Tranches 1 through 4 under its previously announced convertible loan agreements.”
This follows recent reporting that Blockstream CEO Adam Back committed to lead a 750 million kronor (~$79 million) funding initiative for H100, anchored by a 150 million-krona injection in Tranche 6. The loan, structured for speed and cost-efficiency, was priced at 6.38 kronor per share—a 33% premium to market—showing investor confidence.
The loan structure includes settlement flexibility—either in cash or Bitcoin—which allows counterparties to opt for BTC delivery, reducing fiat friction and lining up with the firm’s long-term treasury outlook.
“Unexpectedly, given the strong reception, Tranches 1-4 became in-the-money rapidly,” Back told CoinDesk. “I was expecting [H100] would convert them over time as they reached in-the-money status.”
This funding approach allows H100 to bypass traditional rights issues while onboarding capital in a flexible manner. Tranches 7 and 8 are on deck, with room for size increases depending on market appetite.
This also reflects H100’s evolving financial strategy. While the company’s core operations remain focused on AI-driven health and longevity services, its growing Bitcoin position is reshaping how capital is raised, stored, and deployed. As of now, the company’s BTC holdings stand at 169.2 BTC—up from just 24.41 BTC prior to this latest tranche execution.
H100’s stock jumped 22% on Monday in response to the developments.
As the firm continues negotiations for future tranches and explores adoption of BTC as a financial backbone, it positions itself uniquely at the intersection of health tech and decentralized finance.

2025-06-17 18:00:27Quando se fala em Bitcoin, é comum chama-lo de moeda digital ou "investimento especulativo". No entanto, uma das funções mais fundamentais e menos compreendidas do Bitcoin é a sua função como rede de liquidação. Para entender isso, vale compará-lo com os sistemas tradicionais de liquidação, como o SWIFT, e explorar como o Bitcoin oferece uma camada base de transferência de valor global, descentralizada e resistente à censura.
Antes de mais, explico a diferença entre liquidez e liquidação:
Liquidez refere-se à facilidade de converter um ativo em “dinheiro” sem perda de valor.
Liquidação é o processo de concluir uma transação (transferência real de valor entre partes).
SWIFT: a camada de comunicação do sistema financeiro tradicional
O sistema SWIFT (Society for Worldwide Interbank Financial Telecommunication) é uma rede de comunicação entre bancos. Ele não movimenta dinheiro diretamente, mas envia mensagens padronizadas que instruem as instituições financeiras a realizarem transferências. O processo envolve diversos intermediários, é custoso, lento (podendo levar dias) e depende de confiança entre as partes e regulações locais.
Diferente do SWIFT, o Bitcoin é uma rede autossuficiente que permite a liquidação direta de valores entre duas partes, sem necessidade de intermediários. A cada bloco minerado, transações são validadas e registradas de forma imutável em uma base de dados global, transparente e segura: a blockchain.
Liquidação final: Assim que uma transação é confirmada por um número suficiente de blocos, ela é considerada final e irreversível.
Resistência à censura: Não há entidade central que possa impedir ou reverter uma transação válida.
Disponibilidade global: A rede está acessível 24 horas por dia, 7 dias por semana, em qualquer lugar do mundo com acesso à internet.
Assim como o ouro já serviu como base para sistemas monetários, o Bitcoin está se consolidando como uma camada base de valor digital. Essa base pode dar suporte a outras camadas, como:
Lightning Network, que permite transações quase instantâneas e com baixíssimas taxas;
Serviços financeiros tokenizados, que podem usar o Bitcoin como colateral ou meio de liquidação entre instituições.
Ao funcionar como uma rede de liquidação pública e neutra, o Bitcoin oferece uma alternativa ao sistema tradicional, que é fragmentado, fechado e baseado em confiança entre instituições.
Resumindo, mais do que um ativo especulativo, o Bitcoin está emergindo como uma infraestrutura financeira global. Como rede de liquidação, ele elimina intermediários, reduz custos, aumenta a segurança e democratiza o acesso à transferência de valor. Num mundo cada vez mais interconectado e digitalizado, compreender o papel do Bitcoin como camada base pode ser essencial para entender o futuro do dinheiro.

2025-06-17 17:58:15Bitcoin, desde o seu surgimento em 2009, tem gerado uma variedade de histórias de sucesso e fracasso. Algumas dessas histórias são de pessoas que investiram cedo na criptomoeda e colheram os frutos de sua visão precoce, enquanto outras refletem os altos e baixos que caracterizam o mercado altamente volátil de Bitcoin. Ao longo dos anos, muitas dessas histórias tornaram-se emblemáticas, servindo tanto de inspiração quanto de alerta para quem entra nesse mercado.
Histórias de sucesso
O caso de Laszlo Hanyecz – A pizza de 10.000 Bitcoins Uma das histórias mais icônicas e, ao mesmo tempo, um exemplo do potencial e da volatilidade do Bitcoin, envolve Laszlo Hanyecz, um programador americano. Em 2010, Hanyecz pagou 10.000 bitcoins por duas pizzas. Na época, o valor das criptomoedas era tão baixo que essa transação passou despercebida, mas, em retrospectiva, os 10.000 bitcoins pagos por uma simples refeição valeriam centenas de milhões de dólares nos anos seguintes, quando o preço do Bitcoin disparou.
Essa história, muitas vezes citada, é um lembrete da enorme valorização do Bitcoin desde os seus primeiros dias. Embora Hanyecz não tenha ficado rico com essa transação, a história da "pizza de 10.000 bitcoins" tornou-se uma metáfora para o crescimento do Bitcoin, mostrando como uma pequena quantidade da moeda no início poderia ter mudado a vida de alguém para sempre.
O caso de Michael Saylor e a MicroStrategy no presente Michael Saylor, CEO da MicroStrategy, é outro exemplo de sucesso no mundo do Bitcoin. Em 2020, Saylor decidiu transformar a sua empresa numa das primeiras grandes corporações a investir pesadamente em Bitcoin, comprando mais de 100.000 bitcoins. A decisão foi inicialmente vista com ceticismo, mas ao longo do tempo, o preço do Bitcoin subiu consideravelmente, fazendo com que o investimento de Saylor se tornasse extremamente lucrativo. Para ele, o Bitcoin não era apenas um investimento especulativo, mas uma maneira de proteger a sua empresa da inflação e da desvalorização da moeda fiduciária.
Este caso é um exemplo de como uma aposta estratégica em Bitcoin pode resultar em grandes lucros para quem tem visão de longo prazo e confiança no potencial do ativo. A MicroStrategy tornou-se um dos maiores detentores de Bitcoin no mundo corporativo, e Saylor ganhou reconhecimento por ser um defensor do Bitcoin no mundo empresarial.
Histórias de fracasso
O caso de James Howells – O desaparecimento de 8.000 Bitcoins James Howells, um ex-empregado de TI de Gales, é um exemplo clássico de como a volatilidade e a negligência podem resultar em grandes perdas. Em 2013, Howells, que estava a minerar Bitcoin em casa, acumulou 8.000 bitcoins, que valiam cerca de 5.000 libras na época. Quando o mercado estava em queda, ele decidiu limpar o seu computador antigo e jogá-lo fora, sem perceber que os bitcoins estavam guardados em uma carteira digital nesse dispositivo.
Após a ascensão do preço do Bitcoin, Howells tentou recuperar o disco rígido, que estava enterrado numa lixeira em um aterro sanitário. Apesar das tentativas de convencer a cidade a permitir a escavação do aterro, o pedido foi negado, e ele nunca conseguiu recuperar os bitcoins. Este caso é um lembrete de como, sem a devida segurança e cuidado, até mesmo grandes fortunas podem ser perdidas no mundo das criptomoedas.
O colapso da Mt. Gox – A maior exchange de Bitcoin da história Uma das maiores histórias de fracasso envolvendo Bitcoin está relacionada à exchange Mt. Gox, uma plataforma de negociação de Bitcoin que, em 2014, faliu após alegadamente perder cerca de 850.000 bitcoins dos seus clientes, num valor superior a 450 milhões de dólares na época. A Mt. Gox foi, por um período, a maior exchange de Bitcoin do mundo, mas a sua falência foi um marco negativo na história do Bitcoin.
A falência da Mt. Gox foi causada por uma combinação de hacking, erros internos de segurança e má gestão. Embora alguns dos bitcoins perdidos tenham sido recuperados mais tarde, muitos investidores ficaram devastados pela perda dos seus fundos. Este incidente trouxe à tona a importância da segurança nas exchanges de Bitcoin e da responsabilidade das plataformas financeiras no manejo das criptomoedas de seus clientes.
O impacto da volatilidade e da adoção no mercado
As histórias de sucesso e fracasso envolvendo Bitcoin não são apenas anedotas, mas refletem a natureza imprevisível e arriscada do mercado de criptomoedas. O preço de Bitcoin pode flutuar drasticamente, o que significa que investidores podem tanto fazer grandes fortunas quanto sofrer grandes perdas. Enquanto alguns vêem Bitcoin como uma forma de alcançar a liberdade financeira e proteger-se contra a inflação, outros enfrentam o risco de perder tudo, como demonstrado pelos casos de fracasso.
A adoção crescente de Bitcoin em mercados emergentes, bem como a entrada de investidores institucionais, como a MicroStrategy e o próprio Elon Musk, são indicativos de que o Bitcoin está a ser cada vez mais reconhecido como uma alternativa legítima ao sistema financeiro tradicional. No entanto, as falências de exchanges e as perdas de grandes quantidades de Bitcoin destacam a necessidade de uma abordagem prudente e de uma infraestrutura mais robusta para garantir a segurança e a confiança dos utilizadores.
Resumindo, as histórias de sucesso e fracasso em torno do Bitcoin são um reflexo da natureza volátil e emergente desta moeda digital. Enquanto alguns ganharam milhões, outros perderam fortunas devido à falta de precaução, erros de gestão ou simplesmente pelo preço imprevisível da criptomoeda. Através destas histórias, fica claro que, embora o Bitcoin tenha o potencial de gerar grandes recompensas, ele também apresenta riscos significativos. Para aqueles que entram nesse mercado, é crucial estar preparado e consciente dos desafios que podem surgir, garantindo segurança e adotando uma estratégia de longo prazo para lidar com as incertezas e volatilidade do mercado.

2025-06-16 19:02:15Will not live in a pod.
Will not eat the bugs.
Will not get the chip.
Will not get a blue check.
Will not use CBDCs.Live Free or Die.
Why did Elon buy twitter for $44 Billion? What value does he see in it besides the greater influence that undoubtedly comes with controlling one of the largest social platforms in the world? We do not need to speculate - he made his intentions incredibly clear in his first meeting with twitter employees after his takeover - WeChat of the West.
To those that do not appreciate freedom, the value prop is clear - WeChat is incredibly powerful and successful in China.
To those that do appreciate freedom, the concern is clear - WeChat has essentially become required to live in China, has surveillance and censorship integrated at its core, and if you are banned from the app your entire livelihood is at risk. Employment, housing, payments, travel, communication, and more become extremely difficult if WeChat censors determine you have acted out of line.
The blue check is the first step in Elon's plan to bring the chinese social credit score system to the west. Users who verify their identity are rewarded with more reach and better tools than those that do not. Verified users are the main product of Elon's twitter - an extensive database of individuals and complete control of the tools he will slowly get them to rely on - it is easier to monetize cattle than free men.
If you cannot resist the temptation of the blue check in its current form you have already lost - what comes next will be much darker. If you realize the need to resist - freedom tech provides us options.

2025-06-16 18:02:23The former seems to have found solid product market fit. Expect significant volume, adoption, and usage going forward.
The latter's future remains to be seen. Dependence on Tor, which has had massive reliability issues, and lack of strong privacy guarantees put it at risk.
— ODELL (@ODELL) October 27, 2022
The Basics
- Lightning is a protocol that enables cheap and fast native bitcoin transactions.
- At the core of the protocol is the ability for bitcoin users to create a payment channel with another user.
- These payment channels enable users to make many bitcoin transactions between each other with only two on-chain bitcoin transactions: the channel open transaction and the channel close transaction.
- Essentially lightning is a protocol for interoperable batched bitcoin transactions.
- It is expected that on chain bitcoin transaction fees will increase with adoption and the ability to easily batch transactions will save users significant money.
- As these lightning transactions are processed, liquidity flows from one side of a channel to the other side, on chain transactions are signed by both parties but not broadcasted to update this balance.
- Lightning is designed to be trust minimized, either party in a payment channel can close the channel at any time and their bitcoin will be settled on chain without trusting the other party.
There is no 'Lightning Network'
- Many people refer to the aggregate of all lightning channels as 'The Lightning Network' but this is a false premise.
- There are many lightning channels between many different users and funds can flow across interconnected channels as long as there is a route through peers.
- If a lightning transaction requires multiple hops it will flow through multiple interconnected channels, adjusting the balance of all channels along the route, and paying lightning transaction fees that are set by each node on the route.
Example: You have a channel with Bob. Bob has a channel with Charlie. You can pay Charlie through your channel with Bob and Bob's channel with User C.
- As a result, it is not guaranteed that every lightning user can pay every other lightning user, they must have a route of interconnected channels between sender and receiver.
Lightning in Practice
- Lightning has already found product market fit and usage as an interconnected payment protocol between large professional custodians.
- They are able to easily manage channels and liquidity between each other without trust using this interoperable protocol.
- Lightning payments between large custodians are fast and easy. End users do not have to run their own node or manage their channels and liquidity. These payments rarely fail due to professional management of custodial nodes.
- The tradeoff is one inherent to custodians and other trusted third parties. Custodial wallets can steal funds and compromise user privacy.
Sovereign Lightning
- Trusted third parties are security holes.
- Users must run their own node and manage their own channels in order to use lightning without trusting a third party. This remains the single largest friction point for sovereign lightning usage: the mental burden of actively running a lightning node and associated liquidity management.
- Bitcoin development prioritizes node accessibility so cost to self host your own node is low but if a node is run at home or office, Tor or a VPN is recommended to mask your IP address: otherwise it is visible to the entire network and represents a privacy risk.
- This privacy risk is heightened due to the potential for certain governments to go after sovereign lightning users and compel them to shutdown their nodes. If their IP Address is exposed they are easier to target.
- Fortunately the tools to run and manage nodes continue to get easier but it is important to understand that this will always be a friction point when compared to custodial services.
The Potential Fracture of Lightning
- Any lightning user can choose which users are allowed to open channels with them.
- One potential is that professional custodians only peer with other professional custodians.
- We already see nodes like those run by CashApp only have channels open with other regulated counterparties. This could be due to performance goals, liability reduction, or regulatory pressure.
- Fortunately some of their peers are connected to non-regulated parties so payments to and from sovereign lightning users are still successfully processed by CashApp but this may not always be the case going forward.
Summary
- Many people refer to the aggregate of all lightning channels as 'The Lightning Network' but this is a false premise. There is no singular 'Lightning Network' but rather many payment channels between distinct peers, some connected with each other and some not.
- Lightning as an interoperable payment protocol between professional custodians seems to have found solid product market fit. Expect significant volume, adoption, and usage going forward.
- Lightning as a robust sovereign payment protocol has yet to be battle tested. Heavy reliance on Tor, which has had massive reliability issues, the friction of active liquidity management, significant on chain fee burden for small amounts, interactivity constraints on mobile, and lack of strong privacy guarantees put it at risk.
If you have never used lightning before, use this guide to get started on your phone.

2025-06-17 17:56:33Bitcoin, desde o seu lançamento em 2009, tem atraído a atenção de diversos investidores e visionários que acreditam no seu potencial para revolucionar o sistema financeiro global. Ao longo dos anos, várias figuras se destacaram no movimento em torno da criptomoeda, seja como pioneiros que ajudaram a fundá-la, ou como investidores que apostaram no seu futuro. Estes indivíduos desempenharam papéis cruciais no desenvolvimento do Bitcoin, na sua adoção crescente e na sua legitimação no mercado financeiro.
Satoshi Nakamoto
O maior pioneiro do Bitcoin é, sem dúvida, o seu criador, Satoshi Nakamoto. Embora o nome seja um pseudónimo, a sua contribuição para a criação e lançamento do Bitcoin foi fundamental. Em 2008, Nakamoto publicou o famoso whitepaper intitulado "Bitcoin: A Peer-to-Peer Electronic Cash System", detalhando a ideia de uma moeda digital descentralizada que poderia operar sem a necessidade de uma autoridade central, como um banco. Em 2009, ele lançou o software Bitcoin e minerou o primeiro bloco da blockchain, conhecido como "bloco gênese".
Satoshi Nakamoto permaneceu uma figura misteriosa, nunca revelando a sua verdadeira identidade. Ele foi responsável pelo desenvolvimento inicial do protocolo, mas desapareceu gradualmente da cena pública por volta de 2011, deixando o projeto nas mãos de uma comunidade crescente de desenvolvedores. A sua identidade permanece desconhecida até hoje, mas o seu impacto na criação de uma nova era digital é inegável.
Hal Finney
Hal Finney foi um dos primeiros colaboradores de Nakamoto e é amplamente reconhecido como o primeiro a receber uma transação de Bitcoin. Em janeiro de 2009, Finney recebeu 10 bitcoins de Nakamoto como parte de um teste de transação, tornando-se uma das primeiras pessoas a acreditar no projeto. Finney, que era um programador e investigador de segurança, desempenhou um papel importante no desenvolvimento técnico do Bitcoin e ajudou a popularizá-lo nas suas primeiras fases.
Finney foi uma figura respeitada na comunidade de criptografia e um defensor do movimento de descentralização digital. Ele continuou a apoiar o Bitcoin até sua morte, em 2014, e é lembrado como um dos maiores pioneiros da moeda digital.
Roger Ver
Roger Ver, conhecido como o "Bitcoin Jesus", foi um dos primeiros investidores e “evangelistas” do Bitcoin. Ver ficou fascinado com o conceito de uma moeda descentralizada e investiu cedo em vários projetos relacionados ao Bitcoin. Ele foi um dos primeiros a reconhecer o potencial disruptivo do Bitcoin, defendendo a sua adoção global e promovendo o seu uso como meio de pagamento.
Ver também foi uma das figuras centrais na criação de empresas e iniciativas que ajudaram a impulsionar o ecossistema Bitcoin. Embora tenha sido uma figura polêmica, devido às suas opiniões fortes sobre a escalabilidade do Bitcoin, e tenha se afastado da blockchain original do Bitcoin em favor do Bitcoin Cash, sua contribuição para a popularização da moeda é inegável.
Tim Draper
Tim Draper é um dos investidores mais conhecidos no espaço do Bitcoin e um defensor da sua adoção em larga escala. Em 2014, Draper comprou quase 30.000 bitcoins, que foram apreendidos pelo governo dos Estados Unidos em uma operação contra o mercado Silk Road. Draper fez essa compra por cerca de 19 milhões de dólares, e ele tem sido uma figura-chave na promoção do Bitcoin como uma alternativa viável às moedas fiduciárias.
Draper, um investidor de risco de renome e fundador da Draper Associates, é conhecido por sua visão de longo prazo e pela sua confiança na ascensão das criptomoedas. Ele tem defendido o Bitcoin como uma ferramenta para democratizar o acesso ao dinheiro e acredita que a adoção do Bitcoin vai crescer exponencialmente nos próximos anos.
Michael Saylor
Michael Saylor, CEO da MicroStrategy, é uma figura importante na adoção institucional do Bitcoin. Em 2020, Saylor fez uma aposta significativa ao comprar mais de 100.000 bitcoins para a sua empresa, transformando-a na primeira companhia pública a ter Bitcoin como reserva de valor no seu balanço. Saylor tem defendido publicamente o Bitcoin como uma proteção contra a inflação e uma alternativa mais segura ao dinheiro fiduciário. A sua aposta ajudou a legitimar o Bitcoin no mundo corporativo e inspirou outras empresas a seguir o seu exemplo.
A sua posição em relação ao Bitcoin tem sido clara: ele acredita que o futuro financeiro do mundo está no Bitcoin, e a sua empresa serve como um exemplo para outras grandes corporações a adotarem a moeda digital.
Resumindo, os pioneiros e investidores que contribuíram para o crescimento e a difusão do Bitcoin desempenharam papéis vitais na evolução desta tecnologia disruptiva. Desde o misterioso Satoshi Nakamoto até figuras como Hal Finney, Roger Ver, Tim Draper e Michael Saylor, o Bitcoin tem sido moldado por pessoas com uma visão única sobre o futuro do dinheiro e da liberdade financeira. Através da sua perseverança e crença no potencial do Bitcoin, esses indivíduos ajudaram a estabelecer as bases para a adoção global da moeda digital, transformando-a de uma ideia inovadora em uma força revolucionária no sistema financeiro. O futuro do Bitcoin dependerá, em grande parte, da continuidade da sua evolução e da adoção por mais pessoas e instituições, mas é indiscutível que os pioneiros e investidores desempenharam um papel fundamental na sua ascensão.

2025-06-16 18:02:23What is KYC/AML?
- The acronym stands for Know Your Customer / Anti Money Laundering.
- In practice it stands for the surveillance measures companies are often compelled to take against their customers by financial regulators.
- Methods differ but often include: Passport Scans, Driver License Uploads, Social Security Numbers, Home Address, Phone Number, Face Scans.
- Bitcoin companies will also store all withdrawal and deposit addresses which can then be used to track bitcoin transactions on the bitcoin block chain.
- This data is then stored and shared. Regulations often require companies to hold this information for a set number of years but in practice users should assume this data will be held indefinitely. Data is often stored insecurely, which results in frequent hacks and leaks.
- KYC/AML data collection puts all honest users at risk of theft, extortion, and persecution while being ineffective at stopping crime. Criminals often use counterfeit, bought, or stolen credentials to get around the requirements. Criminals can buy "verified" accounts for as little as $200. Furthermore, billions of people are excluded from financial services as a result of KYC/AML requirements.
During the early days of bitcoin most services did not require this sensitive user data, but as adoption increased so did the surveillance measures. At this point, most large bitcoin companies are collecting and storing massive lists of bitcoiners, our sensitive personal information, and our transaction history.
Lists of Bitcoiners
KYC/AML policies are a direct attack on bitcoiners. Lists of bitcoiners and our transaction history will inevitably be used against us.
Once you are on a list with your bitcoin transaction history that record will always exist. Generally speaking, tracking bitcoin is based on probability analysis of ownership change. Surveillance firms use various heuristics to determine if you are sending bitcoin to yourself or if ownership is actually changing hands. You can obtain better privacy going forward by using collaborative transactions such as coinjoin to break this probability analysis.
Fortunately, you can buy bitcoin without providing intimate personal information. Tools such as peach, hodlhodl, robosats, azteco and bisq help; mining is also a solid option: anyone can plug a miner into power and internet and earn bitcoin by mining privately.
You can also earn bitcoin by providing goods and/or services that can be purchased with bitcoin. Long term, circular economies will mitigate this threat: most people will not buy bitcoin - they will earn bitcoin - most people will not sell bitcoin - they will spend bitcoin.
There is no such thing as KYC or No KYC bitcoin, there are bitcoiners on lists and those that are not on lists.

2025-06-17 19:01:30Bluebird Mining Ventures Ltd., a UK-listed gold exploration company, has made headlines after announcing it will convert future revenues into bitcoin. This is the first time a UK mining company has committed to having a bitcoin treasury.
Bluebird Mining on X
The news sent Bluebird’s stock flying, rising 63% to £0.6 in 48 hours.
Bluebird which has gold projects in South Korea and the Philippines says this is part of a broader plan to modernize how it manages its finances.
“By adopting a ‘gold plus a digital gold’ strategy, it offers the Company an opportunity to turn the page and look to the future and seek to attract a new type of shareholder,” said Aidan Bishop, Interim CEO and Executive Director.
The company’s management believes bitcoin’s rise as a financial asset reflects growing dissatisfaction with traditional stores of value like gold.
Gold has been a reliable hedge against inflation for centuries, but bitcoin is now being seen as a digital alternative – thanks to its limited supply and independence from central bank policies.
Related: Gold at Historic Low Against Bitcoin | A Paradigm Shift?
“Gold’s position as a store of value has been under threat due to the rising global adoption of bitcoin, which some commentators have described as ‘digital gold’,” Bluebird said in a statement.
The plan is simple. Revenue from Bluebird’s gold mining projects will be used to buy bitcoin. The company says this will allow it to preserve capital and have growth potential through exposure to the digital asset market.
The digital asset will be held on the company’s balance sheet as a long-term reserve asset, just like some companies hold gold or cash. Bluebird sees this as proactive, especially in today’s volatile world of inflation, high debt, and global geopolitical tensions. Bishop said:
“I am convinced that we are witnessing a tectonic shift in global markets and that Bitcoin will reshape the landscape of financial markets on every level.”
Bluebird Mining Ventures is a small but big-thinking company.
With 7 employees and operations across Asia, it’s focused on reopening high-grade gold mines that have been closed. Its main projects are the Gubong and Kochang mines in South Korea and the Batangas Gold Project in the Philippines.
In May 2025, the company renewed its mining permit in the Philippines and is finalizing a deal with its local partner to have a “free carry” — meaning it will hold a share of the future profits without putting in any more money.
At the same time, Bluebird is preparing legal action in South Korea to protect its existing assets there, so while it loves Bitcoin, it hasn’t forgotten its mining roots.
To lead this transformation, Bluebird is currently looking for a new CEO with Bitcoin experience. The company says the right leadership will be key to navigating this hybrid financial model that combines traditional resource extraction with modern financials.

2025-06-17 17:54:26Bitcoin, desde a sua criação, tem sido um dos ativos mais debatidos no mundo financeiro, tanto pelos seus seguidores apaixonados quanto pelos céticos. A sua volatilidade extrema e o impacto que tem causado no sistema financeiro tradicional tornaram-no objeto de especulação constante. À medida que o tempo passa, a adoção de Bitcoin cresce e surgem novas discussões sobre o seu futuro, tanto no que diz respeito ao seu preço quanto à sua integração no sistema financeiro global. Neste contexto, existem várias previsões para o futuro de Bitcoin, com cenários tanto otimistas quanto cautelosos, baseados em fatores como regulamentação, adoção institucional e inovação tecnológica.
O preço de Bitcoin: previsões e fatores de influência
Adoção Institucional: A crescente adoção de Bitcoin por grandes empresas e investidores institucionais tem sido vista como um fator de valorização. Organizações como Tesla, MicroStrategy e Square já incorporaram Bitcoin nas suas reservas de tesouraria, o que gerou uma maior confiança no ativo como uma reserva de valor. À medida que mais empresas sigam esse caminho, a demanda por Bitcoin pode aumentar, pressionando o preço para cima.
Regulação Governamental: A forma como os governos lidam com Bitcoin é um dos maiores fatores de incerteza. Uma regulação excessiva pode restringir o acesso e diminuir o interesse, enquanto uma abordagem mais amigável pode impulsionar a adoção e aumentar o preço. Em países como El Salvador, que adotaram o Bitcoin como moeda legal, observa-se uma tendência positiva, mas em muitas outras nações, a regulação ainda é um grande desafio.
Oferta Limitada: A oferta de Bitcoin é limitada a 21 milhões de unidades, o que significa que não há risco de inflação ou aumento da quantidade disponível. Este facto torna Bitcoin particularmente atraente como reserva de valor, especialmente em tempos de incerteza económica global, o que pode continuar a impulsionar a sua valorização a longo prazo.
Tecnologia e Escalabilidade: Inovações como a Lightning Network e o Taproot, que visam melhorar a escalabilidade e a eficiência das transações, podem contribuir para uma adoção mais ampla, o que, por sua vez, poderia ter um impacto positivo no preço. Se Bitcoin se tornar mais acessível e viável para transações diárias, a sua utilidade será mais valorizada no mercado.
Adoção global do Bitcoin: o caminho para a inclusão financeira
A adoção global de Bitcoin está a crescer, especialmente em regiões onde os sistemas financeiros tradicionais são ineficazes ou limitados. Países com economias instáveis, como nações com alta inflação ou crise cambial, estão cada vez mais a ver no Bitcoin uma alternativa viável. Além disso, a inclusão financeira é um dos maiores motores dessa adoção, uma vez que Bitcoin pode oferecer serviços financeiros a populações que estão fora do alcance dos bancos tradicionais.
Mercados Emergentes: Em países como o Brasil, Argentina, Nigéria e outros mercados emergentes, a procura por Bitcoin tem crescido, pois as pessoas procuram proteger os seus ativos da desvalorização das suas moedas locais. Nesses locais, Bitcoin surge como uma alternativa de reserva de valor e meio de troca que não está sujeita ao controlo de uma autoridade central.
Adoção por Governos e Empresas: A crescente aceitação de Bitcoin por grandes empresas e governos pode acelerar a sua integração nas economias globais. Países como El Salvador demonstraram que é possível adotar Bitcoin como uma moeda oficial, enquanto grandes empresas estão cada vez mais a aceitar Bitcoin como forma de pagamento, o que legitima ainda mais o seu uso no comércio global.
Educação e Acessibilidade: A medida que mais pessoas compreendem o funcionamento do Bitcoin e as suas vantagens em termos de segurança, privacidade e liberdade financeira, a adoção tende a crescer. A simplicidade das plataformas de exchange e as melhorias em termos de usabilidade das carteiras digitais tornam mais fácil para os utilizadores entrarem no mercado e utilizarem Bitcoin no seu dia a dia.
Cenários futuros: otimismo ou cautela?
O futuro do Bitcoin é incerto, mas diversos cenários podem se desenrolar. O cenário otimista aponta para uma maior valorização e adoção global, impulsionada pela inovação tecnológica, aumento da confiança institucional e a busca por uma alternativa descentralizada ao sistema financeiro tradicional. Nesse cenário, Bitcoin poderia tornar-se uma forma amplamente aceite de pagamento e uma reserva de valor global, com preços que poderiam ultrapassar os valores mais elevados já registados.
Por outro lado, o cenário cauteloso sugere que os obstáculos como regulação governamental, competição com outras moedas digitais e possíveis falhas tecnológicas podem impedir que o Bitcoin se torne uma parte central do sistema financeiro. Além disso, a volatilidade do preço pode desencorajar aqueles que buscam estabilidade e segurança.
Resumindo, as previsões sobre o preço e a adoção global de Bitcoin são, sem dúvida, complexas e influenciadas por vários fatores. O futuro do Bitcoin dependerá de como a sociedade, os governos e as empresas responderão a essa nova forma de dinheiro. Embora o potencial de valorização seja significativo, o risco e a volatilidade são características que não podem ser ignoradas. À medida que a adoção global cresce e a tecnologia evolui, será necessário acompanhar de perto os desenvolvimentos que irão moldar o futuro de Bitcoin no sistema financeiro global.

2025-06-17 19:01:10In a quiet corner of the world, bitcoin mining operations in Africa are turning electricity into digital currency and in the process, redefining how value is created.
At its core, bitcoin mining involves validating transaction information before adding new blocks to the Bitcoin blockchain by competing to solve a cryptographic puzzle that meets a specific criterion.
Globally, mining plays a key role in keeping the blockchain decentralized and secure. The system depends on miners to verify and record transactions, mainly to prevent a problem called double spending, the digital version of using the same money twice.
To understand this better, imagine Charles sends $5 to Amanda. With physical cash, Amanda can trust the note is real and hasn’t been used elsewhere. But with digital currency, copying data is easy, so how can she be sure that the same $5 wasn’t sent to someone else too? That’s the exact problem Bitcoin mining helps solve.
In recent years, Africa has started to draw attention in this space, positioning itself as a key hub in global bitcoin mining. While there may be less than 2 million bitcoin left to be mined from the total 21 million supply, the rise of mining operations in Africa has sparked excitement, creating new jobs and drawing in foreign capital.
Although some countries still grapple with power shortages and the energy demands of mining, many citizens view bitcoin as a more stable store of value and a safeguard against the volatility of their local currencies.
At the same time, Africa’s wealth of hydro, solar, wind, and geothermal resources makes the continent one of the most promising regions for cost-effective and sustainable mining.
What Makes a Large-Scale Bitcoin Mining Operation in Africa?
It all starts with difficulty. Bitcoin mining isn’t just about solving a puzzle, it’s about solving one that keeps getting harder. Mining difficulty refers to how much computational work is needed to generate a number lower than the target hash.
This difficulty automatically adjusts every 2,016 blocks (about every two weeks), depending on how quickly miners solved the previous batch. If mining is fast and efficient, the network increases the difficulty; if miners drop off and block times slow, it reduces it, all to maintain a consistent block production time of roughly 10 minutes.
The significance of mining difficulty lies in the increased demands it places on mining operations. As difficulty rises, miners require more powerful hardware, cost-effective energy sources, advanced infrastructure, and substantial financial investment. These requirements distinguish large-scale mining operations from smaller, casual miners.
In short, it’s the difficulty of mining that births the need for large facilities, massive energy inputs, industrial-grade hardware, and significant financial investment, the very traits that define a “large” bitcoin mining operation.
This leads us to the 4 key factors that define large Bitcoin mining operations in Africa, each one a direct response to the growing demands of the network:
1. Facility size and infrastructure:
The physical size of a mining facility is a direct reflection of its capacity to house mining equipment and support systems. Larger operations typically have thousands of mining rigs installed, supported by extensive infrastructure such as advanced cooling systems and stable power supplies.
These are critical to ensure that the equipment runs continuously and efficiently, given the intense heat and electricity demands of mining.
While it is possible to mine Bitcoin using desktop computers or gaming rigs by joining mining pools, these setups are limited in profitability. Mining pools distribute rewards based on the computational power contributed, meaning small or less efficient machines earn only modest returns.
To compete effectively, mining operations invest in specialized hardware known as Application-Specific Integrated Circuit (ASIC) miners. These machines are far more powerful and energy-efficient than regular computers but require significant capital investment, with prices ranging from $4,000 to $12,000 per rig depending on their performance.
Large-scale operations typically deploy hundreds or thousands of these ASIC miners, which necessitates the large facilities and sophisticated infrastructure mentioned earlier. In this way, the size of the facility and the sophistication of the mining equipment are tightly linked, together defining the overall scale and capability of a bitcoin mining operation.
2. Hashrate contribution:
Hashrate refers to the computational power used to mine and process transactions on the Bitcoin network. A higher hashrate indicates a more significant contribution to the network’s security and transaction processing.
Large mining operations often possess substantial hashrate, measured in exa hashes per second (EH/s). For instance, as of July 2024, the Bitcoin network’s hashrate was approximately 733.41 EH/s.
3. Energy consumption and power source:
Bitcoin mining is energy-intensive. The total energy consumption of the Bitcoin network has been estimated at 175.87 terawatt-hours annually, comparable to the power consumption of Poland. Large mining operations often seek locations with access to cheap and reliable energy sources, such as hydroelectric, solar, or wind power, to reduce operational costs and environmental impact.
4. Financial banking and investor interest:
Significant financial investment is required to establish and maintain large-scale mining operations. This includes the cost of mining hardware, facility construction, energy procurement, and operational expenses. Companies with substantial financial backing can invest in cutting-edge technology and infrastructure, enhancing their mining capabilities.
Overview of Bitcoin Mining in Africa
Africa is beginning to carve out its share of the global Bitcoin mining market, which was valued at $2.45 billion in 2024 and is projected to reach $8.24 billion by 2034.
As Bitcoin’s value continues to rise, countries across the continent are positioning themselves to benefit, many by tapping into abundant renewable energy sources and taking advantage of regulatory ambiguity or excess energy production.
Ethiopia currently leads the continent in Bitcoin mining activity, with around 2.5% of the global hashrate reportedly coming from operations powered entirely by renewable energy.
This energy mismatch has attracted major miners from China and other regions, who see an opportunity to monetize surplus electricity. Ethiopia’s success showcases how renewable energy and mining can coexist sustainably while contributing meaningfully to state revenue.
Kenya follows closely behind. As the top geothermal energy producer in Africa, with an installed capacity of 863 MW, the country is using its energy advantage to support sustainable mining.
Nigeria is emerging as a serious contender. While not yet dominant, its large population, increasing tech engagement, and growing interest in using flared gas for mining signal potential for expansion. Nigeria’s complex but evolving regulatory landscape also leaves room for further mining developments as the government explores clearer crypto frameworks.
Malawi represents a more localized model of Bitcoin mining. By converting rainfall-powered microgrids into revenue-generating infrastructure, Malawi shows how small-scale mining can play a powerful role in community development and rural electrification.
In Libya, Bitcoin mining is technically illegal, but that hasn’t stopped it. Despite the ban, underground mining continues to thrive thanks to heavily subsidized electricity. In 2021, Libyan miners accounted for an estimated 0.6% of the global Bitcoin production, the highest in both the Arab world and Africa at the time. Today, mining reportedly consumes around 2% of the country’s electricity, even as it operates in the shadows.
Angola rounds out the list with limited public data but notable potential. The country struggles with energy inefficiencies, losing nearly 40% of its hydroelectric power during transmission. Some reports suggest Bitcoin miners are beginning to capitalize on this otherwise stranded energy, though large-scale operations are yet to surface.
What unites these countries is a shared set of conditions: untapped or mismanaged energy resources, an openness or gray area in regulation, and the growing understanding that Bitcoin mining can serve as a financial incentive to build and stabilize decentralized energy systems.
Whether through massive hydroelectric projects or rural microgrids, Bitcoin mining is emerging as both an energy monetization strategy and a bridge to infrastructure development across Africa.

2025-06-17 18:31:38Como si de resolver un crimen se tratase, en este artículo he querido reflexionar sobre el futuro de los pagos en un mundo cada vez más digital, centrándome en la más que probable desaparición del dinero efectivo, con las monedas digitales de bancos centrales (CBDCs) actuando como arma homicida y los bancos centrales como los verdaderos 'asesinos' de este tipo de dinero. Como veis, sería un pésimo novelista, ya que en el primer párrafo ya he revelado toda la trama.
Introducción.
La mayoría de las transacciones realizadas a diario ya son electrónicas y están gestionadas por bancos o empresas tecnológicas, ya sea a través de ventas de comercio electrónico, pagos presenciales con terminales EMV, tarjetas sin contacto o aplicaciones móviles. Estos pagos son fácilmente rastreables, susceptibles de confiscación y sujetos a censura. A pesar de ello, durante las últimas tres décadas se ha intentado desacreditar al otro tipo de dinero que aún se utiliza hoy en día: el efectivo. Gobiernos de todo el mundo han defendido que eliminar el efectivo es necesario para combatir el lavado de dinero, reducir la evasión fiscal y asegurar una mayor estabilidad de la economía.
¿Cuál puede ser la motivación detrás de todo esto? ¿Es posible que, al analizar al candidato destinado a sustituir al efectivo, encontremos una respuesta?
En este artículo me propongo explorar cuál será el formato del dinero del futuro y si las monedas digitales de bancos centrales (CBDC), cuya implementación está siendo investigada e impulsada actualmente por muchos gobiernos, podrían ser las que acaben definitivamente con el efectivo.
Soy consciente de que hay mucho material e información disponible pero para realizar este artículo me he basado en los siguientes papers:
-
The technology of retail central bank digital currency de Raphael Auer y Rainer Boehme
-
Financial Freedom and Privacy in the Post-Cash World de Alex Gladstein
El crímen a resolver.
La víctima.
El dinero en efectivo (la víctima de este crimen) es el medio de pago físico que utilizamos para realizar transacciones, como billetes y monedas. Es emitido y respaldado por un banco central (en Europa, el BCE, y en Estados Unidos, la Fed), lo que le otorga valor y aceptación general en una economía. Además, representa una deuda del banco central con quien lo posee: al tener un billete, esencialmente el banco central te debe ese valor, comprometiéndose a respaldarlo.
Tener “una deuda del banco central” en el bolsillo ha permitido, durante décadas, realizar transacciones diarias en todo el mundo sin que el comprador deba revelar información al vendedor. Esto es posible porque el sistema se basa en la confianza de que el vendedor podrá intercambiar ese dinero por bienes y servicios en el futuro (confianza mutua en su aceptación futura). Al entregar efectivo, la transacción se liquida al instante, sin intermediarios, verificaciones adicionales ni exposición de datos sensibles como nombres, direcciones o información financiera, lo que facilita el comercio incluso entre desconocidos.
Como en cualquier serie de asesinatos, el detective debe conocer todos los detalles posibles de la víctima para elaborar el perfil del asesino y determinar el móvil del crimen. Siguiendo esta lógica, a continuación presento un conjunto de características del dinero en efectivo que podrían haberle generado "enemigos":
-
Resistente a la censura: El efectivo se intercambia directamente entre dos partes sin necesidad de intermediarios (bancos, plataformas digitales o gobiernos). Esto significa que ninguna entidad puede bloquear o revertir una transacción hecha en persona.
-
Difícilmente rastreable: Las transacciones en efectivo son anónimas, ya que no requieren identificación ni dejan un rastro digital.
-
Difícilmente confiscable: El efectivo, al ser un activo físico, solo puede ser confiscado mediante posesión física directa.
-
Permite cierto nivel de privacidad: El uso de efectivo preserva la privacidad de las personas, ya que no expone datos personales ni patrones de gasto.
-
Independencia de infraestructuras tecnológicas: El efectivo no depende de redes de comunicación, electricidad, internet o sistemas bancarios. En escenarios de apagones, desastres naturales o fallos tecnológicos, el efectivo sigue siendo funcional.
-
Aceptación universal sin intermediarios: El efectivo es aceptado prácticamente en cualquier lugar, sin necesidad de cuentas, dispositivos o aplicaciones.
El arma.
En las series de asesinatos o crímenes en general, hay 3 aspectos clave para resolver un caso y estos son el móvil (es la razón detrás del crimen), la oportunidad(posibilidad real que tuvo el sospechoso para cometer el crimen) y los medios disponibles (capacidad física, técnica o arma para llevar a cabo el crimen). En el crimen a resolver en este artículo he creído conveniente empezar por este último y por tanto como buen amante de los avances tecnológicos, he pedido a chatpgt que me defina una CBDC. Su respuesta debajo:
Una CBDC (Central Bank Digital Currency) o Moneda Digital de Banco Central es una forma de dinero digital emitida y respaldada directamente por el banco central de un país (o países). Es similar al dinero en efectivo (como los billetes y monedas) pero existe únicamente en formato digital.
En resumen, una CBDC es dinero digital seguro, accesible y regulado, diseñado para modernizar los sistemas financieros y facilitar los pagos digitales en la economía. 😊💸
Sin embargo, y muy a mi pesar..., hay un par de puntos que no me han convencido (imagino que sabréis cuáles pero por si acaso, los he marcado en negrita). Por ello, he decidido buscarme las habichuelas por mi cuenta y he encontrado este paper, que creo que puede ser de ayuda: “Central Bank Digital Currencies” del Committee on Payments and Market Infrastructures del Bank for International Settlements. Según se indica en dicho paper;
Establecer una definición precisa de la Central Bank Digital Currency (CBDC) resulta complejo, ya que el concepto abarca diversas ideas y posibilidades. No obstante, su característica esencial es que se trata de una forma de dinero digital emitida directamente por el banco central (una obligación del banco central, denominada en una unidad de cuenta existente) que funciona como medio de intercambio y depósito de valor, y está destinada al público general. Esta característica la distingue del dinero digital utilizado por los bancos comerciales, como las reservas o cuentas de liquidación mantenidas en el banco central.
Llegados aquí, he vuelto a preguntar a chatgpt cuál podría ser el motivo u objetivopara que los bancos centrales estén tan interesados por las CBDCs. Su respuesta, como en el caso anterior, tampoco me ha acabado de convencer:
El Banco Central Europeo busca crear una CBDC, conocida como Euro Digital, con varios objetivos clave; en primer lugar, busca aumentar la inclusión financiera al ofrecer una forma de dinero digital segura y gratuita, accesible para toda la población. Otro objetivo es reforzar la estabilidad financiera, proporcionando una alternativa segura al dinero depositado en bancos privados. Por último, el BCE aspira a promover la innovación en servicios financieros y facilitar pagos transfronterizos más rápidos y eficientes. En conjunto, el Euro Digital busca modernizar la economía europea, proteger su sistema financiero y mantener el liderazgo europeo en la era digital.
Así que, una vez más, me toca aplicar el conocido dicho DYOR (Do Your Own Research). A continuación, mi enfoque:
-
Partiendo de la premisa de que muchos objetos utilizados en crímenes no fueron diseñados originalmente para causar daño, sino que tienen múltiples usos, es evidente que ciertos objetos resultan más propensos a ser utilizados con fines dañinos debido a su diseño. Por ejemplo, un cuchillo de caza, con su hoja afilada y puntiaguda, tiene una capacidad de hacer daño superior a la de un cuchillo de punta redonda.
-
De forma análoga, al analizar las diferentes alternativas de diseño de una CBDC, podríamos identificar aquellos elementos que, intencionadamente o no, facilitan ciertos usos indebidos o riesgos asociados y por ende podríamos intuir también las motivaciones de su creador.
Diseñando una CBDC.
En el artículo titulado “The Technology of Retail Central Bank Digital Currency” de Raphael Auer y Rainer Böhme, los autores analizan el desarrollo de una CBDC mediante un enfoque que parte de las necesidades de los consumidores para fundamentar las decisiones de diseño. Para ilustrar este enfoque, introducen la “CBDC Pyramid”, un modelo que organiza jerárquicamente los aspectos clave del diseño de una moneda digital emitida por un banco central:
En el lado izquierdo de la pirámide exponen las necesidades de los consumidores y seis características asociadas que harían útil a una CBDC:
-
Similar al efectivo con funcionalidad peer-to-peer.
-
Pagos en tiempo real.
-
Operaciones resilientes y robustas.
-
Privacidad.
-
Amplia accesibilidad.
-
Capacidad para pagos transfronterizos.
Y en el lado derecho de la pirámide se describen las decisiones de diseño asociadas a cada una de estas características:
-
Reclamaciones indirectas o directas, y ¿qué papel operativo tendrá el banco central?
-
El modelo de centralización (centralizado o descentralizado).
-
Basado en tokens o en balances.
-
Permitir la integración con otras CBDCs.
La tesis sobre la que se construye el paper de Raphael y Rainer se basa en considerar que la principal necesidad del consumidor debe ser poder contar con una CBDC que represente un derecho similar al efectivo y que idealmente sea fácilmente transferible en entornos de transacciones P2P.
A continuación el paper analiza, para cada una de las capas de la pirámide las elecciones disponibles para determinar cuál de ellas es la que acercaría más a una CBDC a las características del cash:
Nivel 1. CBDC directa o indirecta.
A bajo del todo de la pirámide Raphael Auer y Rainer Böhme sitúan la elección de la arquitectura operacional y como se atenderá la demanda del consumidor final. ¿El consumidor "hablará" directamente con el Banco Central y será este quien centralice todo el proceso? ¿o lo hará a través de intermediarios (banca privada)? En cualquiera de los casos, en el paper se asume que solo el banco central podrá emitir la CBCD.
Las principales diferencias en la elección en la base de la pirámide radican en la estructura de los reclamos legales y en los registros mantenidos por el banco central. En el modelo de “CBDC indirecta”, el consumidor tiene un reclamo sobre un intermediario, mientras que el banco central solo lleva un registro de las cuentas mayoristas. En el modelo de “CBDC directa”, la CBDC representa un reclamo directo sobre el banco central, que mantiene un registro de todos los saldos y los actualiza con cada transacción.
Es importante tener en cuenta que los pagos electrónicos deben afrontar interrupciones de conectividad o pagos sin conexión, lo que implica asumir riesgos por parte de los intermediarios y la relación con el cliente, basada en los procesos de Know Your Customer (KYC), permite al intermediario asumir dichos riesgos. Por lo tanto, a menos que un banco central asumiera la responsabilidad del KYC y la debida diligencia del cliente (lo que requeriría una expansión masiva de sus operaciones, muy por encima de sus mandatos actuales), le resultaría difícil asumir un modelo de "CBDC directa".
Nivel 2. Base de datos centralizada o descentralizada.
En el segundo nivel de la pirámide se encuentra la elección de tener un libro mayor centralizado o distribuido.
En un modelo de CBCD directa con base de datos centralizada, las capacidades tecnológicas del banco central deberían ser enormes ya que sería él solo quien procesaría todas las transacciones de todos los ciudadanos (lo que dificulta enormemente su implementación). Además, la principal vulnerabilidad de una arquitectura con un libro mayor centralizado de esta envergadura es la falla del nodo principal.
Por otro lado, actualmente disponer de un libro mayor distribuido (DLT) implica un rendimiento de transacciones menor que las arquitecturas convencionales debido a las dificultades para ejecutar un mecanismo de consenso eficiente y seguro ya que cada actualización del libro mayor debe armonizarse entre los nodos de todas las entidades. Estos modelos podrían ser válidos para jurisdicciones muy pequeñas pero complicado en jurisdicciones más grandes debido al alto número de transacciones que deberían procesar.
Por otro lado, en un modelo de CBCD indirecta ambos enfoques podrían ser factibles.
Nivel 3. Basado en tokens o en balances.
Una vez que se haya elegido la arquitectura y la infraestructura de la CBDC, surge la cuestión de quién tiene la custodia de los fondos y de cómo y a quién se debe otorgar acceso a dichos fondos.
Los activos en moneda digital son fungibles (bienes o activos que pueden intercambiarse entre sí sin que haya una diferencia en su valor o utilidad), por lo que, en principio, pueden tomar la forma de saldos (“acceso basado en cuentas”) o de tokens (“acceso basado en tokens”).
En un sistema de moneda digital basado en saldos (account based access), se debe registrar en algún lugar un número que represente el tamaño de un conjunto de activos, y las transacciones sucesivas deben resultar en cambios en ese número. En este tipo de sistemas, el propietario de los activos debe proporcionar una identificación (derecho basado en la identidad) para acceder al saldo y realizar una transacción, de ahí entre otras, la necesidad del proceso de KYC.
Por el contrario, con los tokens, todo lo que se necesita para realizar una transacción es el conocimiento de las claves criptográficas que los desbloquean. En este tipo de sistemas, los fondos son de quien es capaz de desbloquearlos y las transacciones realizadas no tienen porque estar directamente asociadas a una identidad por lo que es un sistema mucho más parecido al efectivo.
Nivel 4. Integración entre CBDCs.
¿Será posible utilizar la CBDC emitida por el banco central exclusivamente en territorio nacional o también en el extranjero? ¿Estarán dispuestos los bancos centrales a coordinar esfuerzos en el diseño de estas monedas digitales para permitir que los consumidores gestionen múltiples divisas en una sola wallet? De ser así, se facilitaría un comercio internacional más ágil y se eliminaría el vínculo actual entre un pago en el extranjero y la necesidad de realizar una transacción de cambio de divisas (junto con las comisiones asociadas).
En el sistema actual, primero se adquiere moneda nacional, que luego debe ser cambiada por la divisa extranjera, lo que implica costos y demoras. El modelo con pagos transfronterizos integrados permitiría a los consumidores comprar directamente la CBDC del país extranjero antes de realizar sus compras, eliminando así ese paso innecesario e ineficiente y reduciendo los costos asociados al tipo de cambio.
El diseño previsible (mi apuesta personal).
Aquí perdonadme pero voy a ir al grano con mi predicción:
- Creo que la implementación final será el de una CBDC indirecta ofrecida por intermediarios (los bancos privados) con libro mayor centralizado, basada en cuentas en lugar de tokens y con ciertas restricciones en la interoperabilidad entre CBDCs de distintos países.
¿Por qué pienso esto? En primer lugar, como se mencionó anteriormente, una CBDC directa implicaría un cambio significativo en el sistema financiero al transferir gran parte de las responsabilidades de los bancos privados al banco central. En el sistema actual, los bancos privados desempeñan un papel clave en la creación de dinero a través del proceso de concesión de préstamos y la gestión de depósitos. Sin embargo, con una CBDC directa, el banco central sería responsable de emitir dinero digital directamente a los ciudadanos, lo que reduciría drásticamente la necesidad de que los bancos privados gestionen depósitos minoristas.
Esto no solo limitaría su capacidad de crear dinero a través del crédito, sino que también afectaría su modelo de negocio, ya que se reducirían sus fuentes tradicionales de ingresos. Además, podría disminuir su relevancia en el sistema financiero, dejándolos casi fuera de la ecuación en cuanto a la emisión de dinero.
Por otro lado, considero que el modelo con libro mayor centralizado se impondrá principalmente por dos razones: las limitaciones actuales en cuanto a la capacidad de procesamiento de los sistemas distribuidos (DLT) por las reglas de consenso y el interés de los estados en mantener sus capacidades de monitoreo financiero.
En cuanto a la elección entre un sistema basado en tokens o en balances, es importante destacar que, dado que las transacciones en un sistema basado en tokens no están directamente vinculadas a una identidad, resulta más complejo utilizar una CBDC como herramienta de vigilancia o perfilado por parte del banco central o los intermediarios financieros. Este enfoque preserva en mayor medida la privacidad de los usuarios, alineándose con principios similares a los del efectivo digital.
Por tanto, es altamente probable que tanto el Banco Central Europeo como la Reserva Federal opten por un sistema vinculado a una identidad, ya que, además de facilitar el cumplimiento normativo en materia de prevención de delitos financieros, guarda mayor similitud con el modelo de cuentas corrientes tradicional. De hecho, diversos informes, han señalado que la identificación de los usuarios en una CBDC es un factor clave para garantizar la trazabilidad y evitar el anonimato absoluto, lo que refuerza la posibilidad de que el sistema basado en balances sea el elegido.
Finalmente, pienso que facilitar el acceso sencillo a monedas de otros países que se perciben como más seguras podría llevar a una fuga de capitales hacia estas divisas y la ley de Gresham está a mi favor:
La ley de Gresham establece que, cuando en un mercado circulan simultáneamente dos tipos de dinero con el mismo valor nominal pero diferente valor percibido o estabilidad, la “moneda mala” desplaza a la “moneda buena”: los consumidores prefieren conservar la moneda con mayor valor intrínseco como reserva de valor, utilizándola menos en transacciones diarias, lo que eventualmente lleva a su retirada del mercado como medio de pago.
Básicamente esto quiere decir que en el escenario planteado, si los ciudadanos tuvieran acceso directo y fácil a CBDCs de países con economías más estables o con menor inflación, podrían optar por ahorrar en estas monedas más fuertes mientras usan la moneda local para pagos diarios. Esto no solo reduciría la demanda de la moneda nacional, sino que también podría debilitar su estabilidad y aumentar la fuga de capitales.
El móvil.
¿Podrán las personas poseer y controlar su propio dinero y decidir qué hacer con él, o estarán todas sus opciones de pago sujetas a la supervisión y el permiso de intermediarios?
Para ser capaz de contestar a esta pregunta me he basado en el artículo “Retail Central Bank Digital Currency: Motivations, Opportunities, and Mistakes” de Geoffrey Goodell, Hazem Danny Al Nakib y Tomaso Aste que sugiere que los gobiernos buscaran mantener el control sobre su sistema financiero y facilitar la supervisión y regulación de las transacciones a través de las CBDCs y de ahí el diseño con el que las están desarrollando. Dicho esto y aunque en el apartado anterior ya se han podido vislumbrar algunas posibles motivaciones, estas las voy a resumir a continuación:
-
Soberanía monetaria y financiera: Uno de los principales motores detrás de la exploración de las CBDCs son las preocupaciones institucionales sobre los riesgos emergentes para la soberanía monetaria y financiera. Esto es particularmente relevante para los bancos centrales y los gobiernos, que observan cómo el panorama de los pagos evoluciona rápidamente debido a innovaciones tecnológicas y cambios en las preferencias de los consumidores. Además, la creciente facilidad para acceder a divisas extranjeras, especialmente aquellas consideradas más estables o fuertes, está disminuyendo el uso de la moneda local en algunos países. Esto representa un riesgo directo para la soberanía monetaria, ya que reduce la efectividad de las políticas monetarias nacionales.
-
Control total sobre los estímulos económicos: Un sistema de CBDC plenamente operativo podría otorgar a los bancos centrales un control detallado sobre el estímulo fiscal, permitiéndoles distribuir fondos de manera segmentada con solo presionar un botón. En un escenario donde el efectivo físico desapareciera, las CBDC podrían facilitar la aplicación de tasas de interés negativas, obligando a los ciudadanos a pagar una tarifa por mantener ahorros en sus cuentas. Además, este tipo de moneda digital podría proporcionar a los gobiernos la capacidad de confiscar fondos con mayor facilidad, sancionar a disidentes políticos o incluso automatizar multas por infracciones menores, lo que ha suscitado preocupaciones sobre el potencial abuso de estas herramientas. Finalmente, y por si esto fuera poco, existen estudios que exploran la posibilidad de que las CBDCs puedan utilizarse para rastrear y potencialmente restringir o desincentivar ciertas compras con una alta huella de carbono, integrándolas en un sistema de créditos de carbono personales. Un posible escenario podría ser el siguiente:
-
Al intentar comprar gasolina o diésel, la CBDC verifica la huella de carbono acumulada del usuario.
-
Si el usuario ha superado su límite mensual de emisiones, la transacción podría ser rechazada automáticamente o estar sujeta a un recargo adicional por exceder su cuota.
-
Como alternativa, el usuario podría adquirir créditos de carbono de otros ciudadanos que hayan consumido menos, creando así un mercado de intercambio de emisiones a nivel individual.
Esto no debe sorprender a nadie considerando que el sistema Cap and Trade ya se encuentra implementado en la actualidad. Bajo este esquema, empresas con altas emisiones de CO₂ (como aerolíneas, fábricas e industrias de transporte) deben comprar créditos de carbono cuando superan su límite permitido de emisiones. Por tanto el sistema sería el mismo pero aplicado directamente a los ciudadanos.
-
Oportunidades para el sector privado: Lo primero que hay que tener en cuenta es que hoy en día, las compras diarias realizadas a través de aplicaciones móviles o tarjetas de crédito tienen poca semejanza con las compras hechas en efectivo y los usuarios de plataformas como Visa, Apple Pay, WeChat o PayPal intercambian su libertad y privacidad por conveniencia o "usabilidad". En este tipo de transacciones se exige y se comparte información personal en lugar de protegerla. Todo esto nos ha de hacer reflexionar sobre la gran oportunidad que se presenta para el sector privado y en concreto para las "Big Tech" si consiguen monetizar toda la información del consumidor que una moneda tipo CBDC podría proporcionar. No es de extrañar entonces que empresas como Google, Amazon, Stripe o Mastercard sean partners de proyectos de investigación de este tipo de monedas digitales. Como "Data harvesters" experimentados son conscientes del tremendo valor en la creación de perfiles de usuarios.
-
Crimen y evasión fiscal: Como comentamos anteriormente, algunos gobiernos intentan asociar el uso del efectivo con el lavado de dinero y la corrupción, lo que les permite justificar la implementación de las CBDCs como una estrategia para combatir estos problemas. Un ejemplo es el Banco Central de Bangladesh, que busca digitalizar todas las transacciones minoristas para 2027, argumentando que esto mejorará la eficiencia, promoverá la inclusión financiera y reducirá la criminalidad. En Nigeria, el e-Naira fue introducido con el objetivo de facilitar el rastreo de fondos, pero la población respondió con protestas y una baja adopción de la moneda digital.
Conclusiones.
Desde mi punto de vista, es poco probable que las democracias aprendan pronto a diseñar CBDCs que garanticen la privacidad, y aún menos que tengan el incentivo de ofrecerlas a sus ciudadanos. Al fin y al cabo, muchas de las características que atraen tanto a políticos como a banqueros centrales son incompatibles con el dinero anónimo. Por ello, creo que la única alternativa viable para preservar la privacidad financiera que ofrece el efectivo es desarrollar herramientas monetarias resistentes al abuso gubernamental.
Pocas veces se ha expresado este problema con tanta claridad como lo hizo Wei Dai en un correo electrónico enviado en febrero de 1995 a la lista de correo de Cypherpunks donde Dai escribió:
"Nunca ha existido un gobierno que, tarde o temprano, no haya intentado reducir la libertad de sus ciudadanos y obtener más control sobre ellos, y probablemente nunca existirá uno.
Por lo tanto, en lugar de tratar de convencer a nuestro gobierno actual de que no lo intente, desarrollaremos la tecnología que hará imposible que el gobierno tenga éxito.
Los esfuerzos para influir en el gobierno (por ejemplo, a través del lobby y la propaganda) son importantes solo en la medida en que retrasen lo suficiente su intento de represión como para que la tecnología madure y se adopte ampliamente.”

Coinbase Announces Bitcoin Rewards Credit Card, Offering up to 4% BTC Back on EverythingCoinbase is launching its first-ever branded credit card in partnership with American Express, set to roll out this fall. Called the Coinbase One Card, it will be available only to U.S. members of Coinbase One, the platform’s monthly subscription service. The card will offer 2% to 4% back in Bitcoin on everyday purchases, along with access to American Express perks.
JUST IN: Coinbase launches credit card allowing users to earn up to 4% bitcoin back on every purchase
pic.twitter.com/d6pdNZV4pi
— Bitcoin Magazine (@BitcoinMagazine) June 12, 2025
This is a first-of-its-kind product for Coinbase, which previously only offered a prepaid debit card with Visa in 2020.
“We see real potential in the combination of Coinbase and crypto with the powerful backing of American Express, and what the card offers is an excellent mix of what customers are looking for right now,” said Will Stredwick, head of American Express global network services, during the Coinbase State of Crypto Summit in New York.
The card is part of a larger push by Coinbase to expand its subscription-based services. Coinbase One costs $29.99/month and includes zero trading fees, higher staking rewards, and customer support perks. The company also announced a cheaper version—Coinbase Basic—for $4.99/month or $49.99/year, which includes fewer features.
Coinbase’s subscription business is growing fast. It brought in $698.1 million in Q1 2025, compared to $1.26 billion in trading revenue. According to William Blair analyst Andrew Jeffrey, this kind of recurring revenue is a big reason why long-term investors are sticking with the stock.
Launched in 2023, Coinbase One now has over a million members. The company has been steadily growing its ecosystem with products like its Base developer platform and a self-custody wallet.
The company has long positioned Bitcoin at the center of its strategy—offering BTC custody services to institutions, supporting Bitcoin ETFs, integrating Bitcoin rewards into its products, and actively advocating for Bitcoin-friendly regulation in Washington. Coinbase also supports Bitcoin development directly through funding grants and engineering support. As the largest publicly traded crypto exchange in the U.S., Coinbase continues to frame Bitcoin not just as an asset, but as the foundation of its long-term vision.

2025-06-16 19:02:16People forget Bear Stearns failed March 2008 - months of denial followed before the public realized how bad the situation was under the surface.
Similar happening now but much larger scale. They did not fix fundamental issues after 2008 - everything is more fragile.
The Fed preemptively bailed out every bank with their BTFP program and First Republic Bank still failed. The second largest bank failure in history.
There will be more failures. There will be more bailouts. Depositors will be "protected" by socializing losses across everyone.
Our President and mainstream financial pundits are currently pretending the banking crisis is over while most banks remain insolvent. There are going to be many more bank failures as this ponzi system unravels.
Unlike 2008, we have the ability to opt out of these broken and corrupt institutions by using bitcoin. Bitcoin held in self custody is unique in its lack of counterparty risk - you do not have to trust a bank or other centralized entity to hold it for you. Bitcoin is also incredibly difficult to change by design since it is not controlled by an individual, company, or government - the supply of dollars will inevitably be inflated to bailout these failing banks but bitcoin supply will remain unchanged. I do not need to convince you that bitcoin provides value - these next few years will convince millions.

2025-06-17 18:01:50MicroStrategy's Debt-Financed Bitcoin Strategy Will Force a Reckoning Within 18 Months - Jessy Gilger
Jessy Gilger from Unchained Capital warned about the sustainability of MicroStrategy's model and its derivatives like MSTY. He predicts that as more companies adopt Bitcoin treasury strategies, "the P&L will matter more as the balance sheet gets commoditized." Within the next 18 months, he expects the current arbitrage opportunities that MicroStrategy exploits will diminish as Bitcoin reaches higher liquidity levels and more competitors enter the space.
His most concerning prediction involves MSTY specifically, which currently offers distributions annualized at 120% - far exceeding the 16-22% he calculates as reasonable from covered call strategies. "If a whale wants out of MSTY in size... they could sell those derivative positions into an illiquid market where there's no bid," potentially causing a 95% collapse similar to what happened with gold mining ETFs during COVID. He advises investors to consider "private pools" for options strategies rather than pooled products where "you're in the pool with everyone else" and subject to forced liquidations.
Pensions Will Drive the Next Major Bitcoin Adoption Wave in 2026-2027 - Adam Back
Adam Back sees institutional adoption accelerating dramatically as pension funds begin allocating to Bitcoin. "The institutional cover of some of the bigger entities that people would reference... you don't get fired for following BlackRock's recommendation," he explained. With BlackRock now suggesting 2% portfolio allocations and the infrastructure finally in place through Blockstream's new Gannett Trust Company, the barriers for institutional adoption are falling rapidly.
Back predicts this will create a "snowball" effect as pension funds realize Bitcoin can help address their massive unfunded liabilities. He noted that financial institutions offering Bitcoin products are "slow movers" with "policies and training materials and guidance that they got to get through," but once activated, the scale will dwarf current retail and ETF flows. The combination of pension fund allocations, continued nation-state adoption, and the mathematical scarcity of Bitcoin leads him to view even $100,000 as "cheap" given where the market is headed.
Traditional Bond Markets Will Collapse as Bitcoin Becomes the Escape Hatch - Sean Bill
Sean Bill sees a massive shift coming as bond markets deteriorate globally. "You peel back the onion. So who benefits from financial repression, right. And inflating your way out of assets," he explained. With Japanese bond yields blowing out and U.S. 30-year yields jumping 10 basis points in a single day, Bill predicts we're witnessing the early stages of a sovereign debt crisis that will drive unprecedented flows into Bitcoin.
He pointed to Japan's MetaPlanet as a preview of what's coming: "The whole bond market of Japan just flowed into a hotel company." As pension funds and institutions realize they can't meet obligations through traditional fixed income, Bitcoin will become the only viable alternative. Bill believes this transition will accelerate once fiduciaries understand Bitcoin's role as "pristine collateral" that can help them "chip away at those unfunded liabilities." His experience getting Santa Clara County's pension into Bitcoin in 2021 showed him firsthand how a 1-3% allocation at $17,000 could have "wiped out the unfunded liability" as Bitcoin approached $100,000.

New Bitcoin Mining Pool Flips Industry Model: "Plebs Eat First" Could Threaten Corporate Dominance
UTXO Management's explosive report forecasts unprecedented institutional demand that could absorb 20% of Bitcoin's circulating supply by 2026. Bitcoin ETFs shattered records with $36.2 billion in year-one inflows, crushing every commodity ETF launch—and they're projected to hit $100 billion annually by 2027.
The real story? ETFs are just the appetizer. Five massive catalysts are converging: wealth platforms eyeing $120 billion from a modest 0.5% allocation across $60 trillion AUM; corporations following MicroStrategy's playbook now holding 803,143 BTC; potential U.S. Strategic Reserve of 1 million BTC; 13 states with active Bitcoin reserve bills; and the rise of BTCfi yield strategies offering 2-15% returns.
The game-changer: these aren't day traders. CFOs, treasurers, and governments are structurally locked buyers seeking BTC-denominated yields, not quick profits. With FASB mark-to-market accounting removing impairment headaches and regulatory clarity accelerating globally, institutions face a stark reality—allocate now or chase exposure at dramatically higher prices.
This isn't another cycle. It's the institutional colonization of Bitcoin.

2025-06-17 17:51:52Com a crescente digitalização do dinheiro, os governos de vários países começaram a desenvolver moedas digitais de banco central (CBDCs - Central Bank Digital Currencies) como resposta à popularização de Bitcoin. Enquanto Bitcoin representa um sistema financeiro descentralizado e resistente à censura, as CBDCs são versões digitais das moedas fiduciárias, controladas diretamente pelos bancos centrais. Essa concorrência pode moldar o futuro do dinheiro e definir o equilíbrio entre liberdade financeira e controlo estatal.
Diferenças fundamentais entre Bitcoin e CBDCs
Bitcoin e as CBDCs diferem em praticamente todos os aspetos fundamentais:
Centralização vs. Descentralização: Bitcoin opera numa rede descentralizada, onde nenhum governo ou entidade pode alterar as regras ou censurar transações. Já as CBDCs são emitidas e controladas pelos bancos centrais, permitindo um maior controlo sobre a circulação e utilização do dinheiro.
Oferta limitada vs. Inflação controlada: Bitcoin tem uma oferta fixa de 21 milhões de unidades, tornando-se um ativo escasso e deflacionário. As CBDCs, por outro lado, podem ser criadas sem limites, como acontece com as moedas fiduciárias tradicionais, sujeitas a políticas monetárias inflacionárias.
Privacidade vs. Monitorização: Bitcoin permite transações pseudónimas, garantindo um certo nível de privacidade financeira. As CBDCs, no entanto, podem ser programadas para permitir o rastreamento total de cada transação, facilitando a supervisão governamental e, potencialmente, o controlo sobre o que os cidadãos podem ou não gastar.
Resistência à censura vs. Controlo estatal: Bitcoin permite que qualquer pessoa realize transações sem depender de aprovação de terceiros. As CBDCs, por serem centralizadas, podem ser usadas pelos governos para restringir transações indesejadas ou mesmo confiscar fundos com um simples comando digital.
O que os governos pretendem com as CBDCs?
A introdução das CBDCs tem sido vendida com argumentos como:
Maior eficiência nas transações financeiras, eliminando intermediários e reduzindo custos bancários.
Facilidade na implementação de políticas económicas, como estímulos diretos à população ou tributação automatizada.
Combate a atividades ilegais, dado que as transações podem ser rastreadas em tempo real.
No entanto, muitas destas justificações levantam preocupações sobre a perda de privacidade financeira e o aumento do poder dos governos sobre o sistema monetário.
Bitcoin como alternativa às CBDCs
A ascensão das CBDCs pode fortalecer a posição de Bitcoin como alternativa de dinheiro verdadeiramente livre. À medida que os cidadãos percebem os riscos de um sistema financeiro 100% controlado pelo Estado, a procura por um ativo descentralizado e resistente à censura pode crescer.
Proteção contra o controlo estatal: Bitcoin permite que os utilizadores mantenham total soberania sobre o seu dinheiro, sem o risco de bloqueios arbitrários ou confiscações.
Preservação da privacidade financeira: Ao contrário das CBDCs, que podem monitorizar todas as transações, Bitcoin oferece um grau de anonimato que protege os indivíduos da vigilância excessiva.
Reserva de valor contra a inflação: Enquanto os governos podem emitir CBDCs indefinidamente, Bitcoin mantém a sua escassez garantida, tornando-se um refúgio contra políticas monetárias irresponsáveis.
Resumindo, a competição entre Bitcoin e as CBDCs será uma das maiores batalhas financeiras do futuro. Enquanto os governos tentam consolidar o seu controlo através de moedas digitais centralizadas, Bitcoin continua a ser a principal alternativa para aqueles que procuram independência financeira e proteção contra a vigilância estatal. A escolha entre um sistema financeiro livre e um sistema monitorizado e controlado poderá definir o rumo da economia digital nas próximas décadas.

2025-06-17 17:49:53Desde a sua criação, Bitcoin tem sido um ativo revolucionário, desafiando o sistema financeiro tradicional e propondo uma nova forma de dinheiro descentralizado. No entanto, o seu futuro ainda é incerto e gera intensos debates. Entre os cenários possíveis, dois extremos destacam-se: a hiperbitcoinização, onde Bitcoin se torna a moeda dominante na economia global, ou a obsolescência, caso a rede perca relevância e seja substituída por outras soluções.
Hiperbitcoinização: o mundo adota Bitcoin como padrão monetário
Perda de confiança nas moedas fiduciárias: Com a impressão excessiva de dinheiro por bancos centrais, muitas economias enfrentam inflação descontrolada. Bitcoin, com a sua oferta limitada de 21 milhões de unidades, apresenta-se como uma alternativa mais confiável.
Adoção crescente por empresas e governos: Alguns países já começaram a integrar Bitcoin na sua economia, aceitando-o para pagamentos e reserva de valor. Se essa tendência continuar, a legitimidade de Bitcoin como moeda global aumentará.
Facilidade de transações globais: Bitcoin permite transferências internacionais rápidas e baratas, eliminando a necessidade de intermediários financeiros e reduzindo custos operacionais.
Avanços tecnológicos: Melhorias na escalabilidade, como a Lightning Network, podem tornar Bitcoin mais eficiente para uso diário, facilitando sua adoção em massa.
Se a hiperbitcoinização acontecer, o mundo pode testemunhar uma mudança radical no sistema financeiro, com maior descentralização, resistência à censura e uma economia baseada em dinheiro sólido e previsível.
Obsolescência: Bitcoin perde relevância e É substituído
Regulações governamentais restritivas: Se grandes potências económicas impuserem regulações severas sobre Bitcoin, a adoção pode ser dificultada, reduzindo sua utilidade.
Falhas tecnológicas ou falta de inovação: Apesar da sua segurança e descentralização, Bitcoin pode enfrentar dificuldades para escalar de forma eficiente. Se soluções melhores surgirem e forem amplamente aceites, Bitcoin pode perder a sua posição de liderança.
Concorrência com alternativas mais rápidas e eficientes: Se outras formas de dinheiro digital conseguirem superar Bitcoin em termos de escalabilidade e usabilidade, a rede pode ver a sua adoção diminuir.
Falta de incentivos para os mineradores: Como a emissão de novos Bitcoins diminui a cada halving, os mineradores dependerão cada vez mais das taxas de transação. Se essas taxas não forem suficientes para sustentar a segurança da rede, pode haver um risco para a sua viabilidade a longo prazo.
Resumindo, o futuro do Bitcoin pode seguir diferentes caminhos, dependendo de fatores como inovação, adoção global e resistência a desafios externos. A hiperbitcoinização representaria uma revolução económica, com um sistema monetário descentralizado e resistente à inflação. No entanto, a obsolescência continua a ser um risco, caso a rede não consiga adaptar-se às exigências futuras. Independentemente do desfecho, Bitcoin já deixou a sua marca na história financeira, abrindo caminho para uma nova era de dinheiro digital e liberdade económica.

2025-06-16 19:02:16Bank run on every crypto bank then bank run on every "real" bank.
— ODELL (@ODELL) December 14, 2022
Good morning.
It looks like PacWest will fail today. It will be both the fifth largest bank failure in US history and the sixth major bank to fail this year. It will likely get purchased by one of the big four banks in a government orchestrated sale.
March 8th - Silvergate Bank
March 10th - Silicon Valley Bank
March 12th - Signature Bank
March 19th - Credit Suisse
May 1st - First Republic Bank
May 4th - PacWest Bank?PacWest is the first of many small regional banks that will go under this year. Most will get bought by the big four in gov orchestrated sales. This has been the playbook since 2008. Follow the incentives. Massive consolidation across the banking industry. PacWest gonna be a drop in the bucket compared to what comes next.
First, a hastened government led bank consolidation, then a public/private partnership with the remaining large banks to launch a surveilled and controlled digital currency network. We will be told it is more convenient. We will be told it is safer. We will be told it will prevent future bank runs. All of that is marketing bullshit. The goal is greater control of money. The ability to choose how we spend it and how we save it. If you control the money - you control the people that use it.

2025-06-17 17:56:49Good health is the most valuable asset in that a human being can have on earth, it is more important than material possessions or money. It emphasize that despite the kind of wealth you have, it is meaningless if you are not physically or mentally well enough to enjoy them!.
There are some positive impact of good health in terms of making money. One need to have good health and see it as the most valuable to enable carefulness is making wealth.
- _Good health enable you to enjoy wealth _
Without good health the ability to enjoy everyday life experiences such as spending time with the love ones, traveling and eating your favorite dishes will be compromised.
- _God health support productivity and earning ability_
Good health give individual and opportunity to work, to be creative and to generate income. But poor health can limit your opportunities or even force you to stop working.
- poor health can be expensive
Chronic illness, surgeries,being admitted in the hospital and medications can cost someone's fortune. Maintaining good health often reduce the need for costly treatment.
- Good health can not be bought (easily).
Individual can buy medicine and other human wants, but you can not truly buy good health. It takes proper nutrition, regular sleep, enough exercise and a good healthy habit.
Emotional and psychological well-being are also part of overall health,. Stress, depression, and anxiety can hinder success and happiness just like physical illness.

2025-06-17 17:49:18Ele é uma espécie de ponte do Tor que permite que os usuários se conectem à rede Tor por meio de um sistema distribuído de voluntários.
A história do Snowflake começou em 2019, quando o Tor Project percebeu que muitas pessoas em locais com restrições de acesso à Internet estavam recorrendo a soluções de VPN e proxies para contornar a censura. No entanto, muitas dessas soluções eram bloqueadas pelas autoridades governamentais, o que criou a necessidade de encontrar novas maneiras de contornar a censura. Foi aí que surgiu a ideia do Snowflake, que foi lançado como uma solução para ajudar a aumentar a capacidade do Tor de contornar a censura da Internet em todo o mundo.
O Snowflake funciona por meio de um sistema distribuído de voluntários que oferecem seus proxies para ajudar a contornar a censura. Quando um usuário se conecta ao Snowflake, seu tráfego é roteado por meio de um conjunto de proxies voluntários que se oferecem para ajudar a contornar a censura. Esses proxies são distribuídos em todo o mundo, o que ajuda a garantir que haja sempre uma opção disponível para os usuários que desejam acessar a Internet livremente.
O Snowflake resolve o problema de acesso à Internet em locais onde o acesso ao Tor é bloqueado. Ele permite que os usuários contornem a censura e a vigilância da Internet, acessando sites e aplicativos que seriam bloqueados em suas regiões. Com o Snowflake, os usuários podem navegar na Internet com mais privacidade e segurança, evitando serem detectados pelos censores da Internet.
"A privacidade é necessária para uma sociedade aberta na era eletrônica. Privacidade não é sigilo. Uma sociedade livre requer privacidade na comunicação, bem como privacidade na busca e na associação." - Eric Hughes

2025-06-17 17:47:57Desde a sua criação, Bitcoin tem sido muito mais do que apenas uma alternativa ao dinheiro tradicional. Com a digitalização crescente da economia global, Bitcoin tem-se afirmado como um pilar fundamental para novas formas de transações, comércio e reserva de valor. A sua descentralização, transparência e resistência à censura tornam-no uma base sólida para economias digitais, onde as interações financeiras ocorrem sem a necessidade de intermediários tradicionais.
As características de Bitcoin na economia digital
Transações globais e sem fronteiras: Qualquer pessoa com acesso à internet pode enviar e receber Bitcoin sem precisar de um banco ou autorização governamental.
Oferta limitada e previsível: Ao contrário do dinheiro fiduciário, que pode ser inflacionado por bancos centrais, Bitcoin tem um limite fixo de 21 milhões de unidades, tornando-o um ativo escasso e confiável.
Segurança e transparência: A blockchain ou timechain de Bitcoin regista todas as transações publicamente, garantindo um sistema seguro e auditável.
Resistência à censura: Nenhum governo ou entidade pode bloquear transações de Bitcoin, permitindo uma economia digital mais livre e acessível.
Com essas características, Bitcoin já está a transformar diversos setores económicos, impulsionando novas formas de comércio e investimento.
Bitcoin no comércio digital e na economia global
E-commerce: Empresas e consumidores podem utilizar Bitcoin para transações internacionais rápidas e sem taxas abusivas.
Remessas internacionais: Trabalhadores que enviam dinheiro para os seus países de origem podem evitar taxas elevadas e transferências demoradas ao utilizar Bitcoin.
Economias emergentes: Em países com moedas instáveis e sistemas bancários pouco confiáveis, Bitcoin serve como uma alternativa segura e descentralizada para armazenamento de riqueza e transações diárias.
Além disso, Bitcoin está a ser adotado por empresas e governos como reserva de valor, reforçando o seu papel como base para a economia digital do futuro.
Desafios e adaptação à nova economia
Volatilidade do preço: A oscilação do valor de Bitcoin pode dificultar o seu uso diário como meio de pagamento.
Regulações e resistência governamental: Alguns países tentam limitar ou regular Bitcoin para manter o controlo sobre o sistema financeiro tradicional.
Educação e adoção: Muitas pessoas ainda desconhecem como utilizar Bitcoin de forma segura e eficiente.
Resumindo, o Bitcoin está a transformar a forma como o mundo interage com o dinheiro, oferecendo uma alternativa descentralizada e transparente para economias digitais. À medida que mais pessoas e empresas adotam Bitcoin para pagamentos, poupança e comércio global, o seu impacto torna-se cada vez mais evidente. Apesar dos desafios, Bitcoin continua a consolidar-se como a base de um novo paradigma económico, onde a liberdade financeira e a inovação tecnológica caminham lado a lado.

2025-06-17 17:46:21A sede do ProtonMail está localizada na Suíça, um país conhecido por suas leis rigorosas de privacidade, embora a empresa tenha enfrentado alguns desafios, como ataques DDoS e pressão do governo suíço, ela continua comprometida em fornecer um serviço seguro e privado aos seus usuários.
O ProtonMail foi fundado em 2014 por um grupo de cientistas do CERN (Organização Europeia para Pesquisa Nuclear) que queriam criar uma plataforma de e-mail segura e privada que usasse criptografia de ponta a ponta. O objetivo era oferecer aos usuários uma alternativa aos serviços de e-mail tradicionais que frequentemente violam a privacidade dos usuários.A equipe fundadora incluía Andy Yen, Jason Stockman e Wei Sun, todos com formação em física e matemática.
Ao longo dos anos, o ProtonMail lançou vários recursos adicionais, incluindo aplicativos móveis para iOS e Android, integração com Tor e a possibilidade de enviar e-mails criptografados para usuários de outros provedores de e-mail. O ProtonMail também lançou uma VPN (rede privada virtual) chamada ProtonVPN, que segue o mesmo compromisso com a privacidade e segurança dos usuários.
A criptografia de ponta a ponta utilizada pelo ProtonMail assegura a proteção de todas as mensagens de seus usuários. O processo de criptografia ocorre no dispositivo do remetente antes do envio das mensagens aos servidores da ProtonMail, onde elas são armazenadas em formato criptografado. Quando o destinatário abre a mensagem, ela é descriptografada no dispositivo do destinatário, garantindo que somente o destinatário possa ler o conteúdo da mensagem. Isso significa que, mesmo que os servidores da ProtonMail sejam violados, as mensagens dos usuários permanecerão seguras e protegidas.
O ProtonMail oferece suporte à autenticação de dois fatores usando chaves de segurança YubiKey. Isso adiciona uma camada extra de segurança ao login da conta do ProtonMail, pois um invasor precisaria não apenas da senha, mas também da chave física para acessar a conta do usuário. A YubiKey é uma opção popular para autenticação de dois fatores, pois é fácil de usar e oferece proteção adicional contra-ataques de phishing e keylogging. O ProtonMail também suporta outras opções de autenticação de dois fatores, aplicativos de autenticação, como o Aegis Authenticator.
Outra funcionalidade importante é a proteção contra phishing e spam. O ProtonMail utiliza algoritmos avançados de filtragem para identificar e bloquear mensagens maliciosas antes que elas cheguem à caixa de entrada do usuário. Isso ajuda a reduzir a quantidade de spam recebida e a proteger contra-ataques de phishing, que tentam enganar o usuário a fornecer informações pessoais.
Passo a passo instalação do aplicativo protonmail no Android:
-
Baixe e instale o aplicativo protonmail em seu dispositivo móvel no F-droid ou obtainium.
-
Clique em "Criar nova conta" se você ainda não tiver uma conta ProtonMail, ou clique em "Fazer login" se já tiver uma conta.
-
Se você está criando uma nova conta, preencha os campos de registro, incluindo seu endereço de e-mail desejado e uma senha forte.
-
Depois de criar ou fazer login em sua conta, você pode usar o ProtonMail em seu dispositivo Android para enviar e receber e-mails seguros e protegidos.
Lembre-se de que, para garantir a privacidade e a segurança de suas informações, é importante usar uma senha forte e habilitar a autenticação de dois fatores. Utilize o Tor para acessar seu e-mail no site onion e considere usar uma VPN.
No Relatório de Transparência do ProtonMail, em muitos casos, a única informação que eles puderam fornecer foi um e-mail de recuperação (opcional na criação da conta) ou o IP que acessou o e-mail.
A própria ProtonMail recomenda o uso do Tor para acesso anônimo ao serviço. Se um juiz exigir a coleta do seu IP, a Proton não terá essa informação se você acessar seu e-mail via o site onion pelo Tor.
Se você é uma pessoa em situação de risco, como um ativista ou alguém que pode ser perseguido por diversos motivos, é essencial tomar medidas excepcionais: 1. Pague pelo serviço com Bitcoin. 2. Não use informações que possam identificá-lo ao se registrar. 3. Utilize o Tor, ou uma VPN, sempre que acessar o ProtonMail.
