Bitcoin Developer Who Worked With Satoshi Just Released A Tool That Changes Online Privacy Forever
Martti Malmi, one of Bitcoin’s earliest developers who worked directly with Satoshi Nakamoto in the protocol’s founding years, has released a new version of Nostr VPN — an open-source mesh VPN that discards the entire trust model underlying conventional virtual private network services and replaces it with cryptographic keys, decentralized relay infrastructure, and user-operated exit nodes. The release was flagged by TFTC (@TFTC21) on X on May 19, describing Nostr VPN as a fundamental departure from the architecture that has defined commercial VPN services for decades. Malmi — known in Bitcoin’s early history as Sirius, the developer who received the first-ever Bitcoin transaction from Satoshi and later maintained bitcoin.org — built Nostr VPN using the Nostr protocol as its signaling and coordination layer, per the TFTC post and the project’s open-source repository on git.iris.to. The Problem With Every VPN You’ve Ever Used The structural flaw at the center of commercial VPN services is straightforward. When a user connects to NordVPN, ExpressVPN, ProtonVPN, or any equivalent service, all internet traffic routes through servers owned and operated by that company. The user trusts the provider not to log, analyze, sell, or hand over that traffic to third parties — including law enforcement. That trust has been violated repeatedly across the industry. Multiple VPN providers marketed as no-log services have subsequently been shown to maintain logs when compelled by legal process, per documented cases cited in the TFTC post. The promise of privacy in a conventional VPN is only as strong as the company behind it — a company with employees, legal addresses, server infrastructure, and obligations to comply with the jurisdictions they operate in. What Nostr VPN Does Differently Nostr VPN eliminates the central server entirely. The architecture operates as a peer-to-peer mesh network — devices connect directly to each other rather than routing through a corporate intermediary. The Nostr protocol handles signaling between nodes using public-key cryptography, the same cryptographic framework that secures Bitcoin transactions, per the project’s repository. Each user’s identity on the network is a cryptographic key pair, not an account or email address tied to a real-world identity. The exit node model is where the practical privacy advantage becomes concrete. A user designates one of their own devices — a home server, a rented VPS from a provider like Hetzner, or any machine they control — as the exit point for their internet traffic. Websites and services see only the IP address of that exit node, not the device actually being used. The critical distinction from a commercial VPN is that the user is the operator. There is no third party between the user and the exit node who could be compelled to produce logs, because no third party holds them, per the project documentation cited in the TFTC post. Why A Bitcoin Developer Built This Malmi’s involvement is not coincidental. The philosophy underlying Nostr VPN maps directly to the same sovereignty argument that animated Bitcoin’s original design — the elimination of trusted intermediaries from a system where that trust represents both a single point of failure and a single point of control. Bitcoin removed trusted third parties from money. Nostr VPN applies the same logic to internet privacy infrastructure. The Nostr protocol itself was built by and for the Bitcoin community from its earliest days, using the same public-key cryptographic primitives and attracting developers who share a specific set of convictions about censorship resistance, self-custody, and the dangers of centralized infrastructure that can be pressured, subpoenaed, or shut down. The release arrives as governments across multiple jurisdictions — including the United Kingdom, per recent legislative developments — move to tighten controls over VPN usage and expand surveillance capabilities. For the nascent sector’s community of privacy-focused users, developers, and holders for whom financial privacy and internet privacy are inseparable concerns, Nostr VPN represents a meaningful step toward infrastructure that cannot be compelled to betray its users — because there is no operator left to compel.

Chainlink Co-Founder Nazarov Reveals 3 Trends He’s Watching Closely
Chainlink co-founder Sergey Nazarov said he is increasingly encouraged by three trends reshaping crypto infrastructure: a stronger industry focus on security, continued product development during quieter markets, and the growth of real-world assets and tokenized finance beyond crypto price cycles. 3 Reasons Nazarov Is Bullish On Chainlink In a lengthy post on X, Nazarov argued that the market is moving toward infrastructure providers that can meet higher reliability standards across DeFi and TradFi. He said this shift is already benefiting Chainlink because the network was “built with security and reliability in mind from the start,” contrasting Chainlink’s 16-node model with “1 of 1 or 2 of 2” systems, which he said can often functionally resemble a single point of failure. “Our industry has started caring much more about the security and reliability of the infrastructure, standards and oracles/dependencies that it is built on top of,” Nazarov wrote. “This shift in focus towards security is already massively benefiting Chainlink because it is built with security and reliability in mind from the start e.g. 16 nodes vs 1 of 1 or 2 of 2.” He added that this focus “makes a better system for everyone in the DeFi/TradFi industry to transact with less risk.” Nazarov said the same dynamic is now playing out in cross-chain interoperability, where he pointed to large users migrating to Chainlink’s Cross-Chain Interoperability Protocol after deeper security reviews of bridging providers. He cited Kraken’s stated rationale for choosing CCIP, including ISO 27001 and SOC 2 Type 2 certifications, secure-by-default architecture, 16 independent nodes and native rate limits. He also referred to Lido’s cross-chain security review, which said Chainlink CCIP provides decentralization, native safeguards and issuer control as protocol-level guarantees, including protections that insulate wstETH from several attack vectors associated with the Kelp and LayerZero exploit . Lombard Finance, according to Nazarov’s cited example, described CCIP as an “enterprise-grade framework to secure high-value assets.” “With over $4Billion migrated in just a few weeks and more on the way, I am clearly seeing the industry’s clear preference for security and reliability being a key trend leading to accelerated adoption of Chainlink and CCIP,” Nazarov wrote. The second trend, Nazarov said, is Chainlink’s ability to keep building through down markets. He framed quieter periods as a productive environment for teams with existing product-market fit, saying less market noise gives builders more room to develop infrastructure for future demand. “Chainlink has always continued to build and added many of its best features during down markets, when there is less noise to distract top teams from building,” he wrote. “Because Chainlink already has clear product market fit, being able to focus on building the future is a powerful accelerant for future progress and is actually what I and many of the people building Chainlink are here for.” Nazarov highlighted both use-case-specific features, such as collateral management, and reusable primitives, including verifiable confidential compute in Chainlink Runtime Environment, or CRE . He said those components are being built, refined and launched with major users. The third trend is the expansion of RWA, TradFi tokenization and digital assets as a market that Nazarov said has “decoupled from crypto prices as a determining factor of its success.” In his view, that creates a more durable opportunity for infrastructure platforms that can combine data, interoperability, identity and compliance, and verifiable off-chain orchestration into end-to-end systems. He pointed to several recent capital markets examples, including DTCC using CRE and Chainlink Data for production plans around 24/7 collateral management, SGX using DataLink, and Chainlink backend integrations involving State Street and Fidelity International. Nazarov said these are only a few examples of broader work across payments, tokenized equities and tokenized funds. The broader thesis is that DeFi applications and TradFi institutions may increasingly converge through shared on-chain standards, interoperability connections and oracle infrastructure. Nazarov closed by framing that convergence as the next major phase for Chainlink, saying the goal is not only to solve isolated market problems, but to help DeFi and TradFi “merge into the new global financial system.” At press time, LINK traded at $9.595.

Bithumb to Temporarily Halt Filecoin (FIL) Deposits and Withdrawals for Network Upgrade
BitcoinWorld Bithumb to Temporarily Halt Filecoin (FIL) Deposits and Withdrawals for Network Upgrade South Korean cryptocurrency exchange Bithumb has announced a temporary suspension of deposits and withdrawals for Filecoin (FIL), effective from 9:00 a.m. UTC today. The exchange cited an upcoming network upgrade as the reason for the halt, a routine but critical process to ensure the blockchain’s stability and functionality. Details of the Suspension The suspension applies to all FIL transactions on Bithumb, one of the largest crypto exchanges in South Korea by trading volume. According to the exchange’s official notice, the halt will remain in effect until the network upgrade is completed and the stability of the new protocol is verified. Bithumb has not specified an exact end time but stated that services will resume automatically once the upgrade is fully implemented and the network is deemed secure. Why Network Upgrades Matter for FIL Holders Filecoin, a decentralized storage network, periodically undergoes network upgrades to improve scalability, security, and efficiency. These upgrades often introduce new features or optimize existing protocols. For users, this means that during the upgrade window, transactions may be temporarily unavailable on exchanges that require network synchronization. Bithumb’s proactive suspension is a standard precaution to prevent transaction errors or asset loss during the transition. What This Means for Traders For FIL holders and traders on Bithumb, the suspension means that they cannot move their tokens in or out of the exchange during this period. However, trading pairs involving FIL on the platform may still be active, depending on the exchange’s internal policies. Users are advised to monitor Bithumb’s official announcements for the exact resumption time. Such suspensions are typically short-lived, often lasting a few hours to a day, but delays can occur if unexpected issues arise during the upgrade. Broader Context: Exchange Suspensions and Market Impact While temporary suspensions are routine in the crypto space, they can sometimes lead to short-term price volatility as traders react to perceived liquidity constraints. However, for a scheduled upgrade, the impact is usually minimal. Filecoin’s price has remained relatively stable in recent trading sessions, reflecting the market’s understanding of the event as a standard technical procedure rather than a cause for concern. Conclusion Bithumb’s decision to suspend FIL deposits and withdrawals is a standard operational measure tied to Filecoin’s network upgrade. Users should expect normal service to resume shortly after the upgrade completes. For now, the best course of action is to stay informed through official Bithumb channels and avoid making time-sensitive transactions involving FIL until the suspension is lifted. FAQs Q1: How long will the FIL suspension on Bithumb last? A1: The exact duration has not been specified, but it will last until the Filecoin network upgrade is complete and verified as stable. Typically, such suspensions last a few hours to a day. Q2: Can I still trade FIL on Bithumb during the suspension? A2: The suspension applies only to deposits and withdrawals. Internal trading on the exchange may still be available, but it is best to check Bithumb’s official announcements for any trading-related restrictions. Q3: What should I do if my FIL transaction is pending during the suspension? A3: Pending transactions may be delayed or cancelled. It is recommended to contact Bithumb customer support for specific guidance on your transaction status.
