Coinbase stated that it is optimizing the rule creation process in its anti-fraud system by integrating machine learning models with a rules engine, achieving more efficient risk management. It also proposed a dual-track strategy of "models responsible for long-term defense, rules responsible for rapid response," and built a unified framework to create a feedback loop between the two: rules are used to capture new types of fraud and train the model in reverse, thereby continuously enhancing overall defense capabilities.In terms of specific optimizations, Coinbase has transformed the previously manual rule creation process into a data-driven and automated recommendation system by restructuring data, automating schema evolution, and introducing notebook-based analytical tools, significantly improving efficiency. Among these improvements, the performance of rule backtesting has increased by more than 10 times, and the overall response time has been reduced from several days to a few hours. Additionally, the new system uses machine learning to recommend parameters, helping to reduce false positive rates while combating fraud and minimizing the impact on normal users. Coinbase indicated that the next step will be to advance event-driven automatic rule generation and explore the "one-click conversion" of efficient rules into model features, further moving towards an automated risk management system.

According to Decrypt, Admiral Samuel Paparo, the commander of the U.S. Pacific Command, stated during a hearing before the U.S. House Armed Services Committee that the U.S. government is currently running a Bitcoin node for cybersecurity-related testing, but is not engaged in mining.Paparo indicated that the U.S. military's interest in Bitcoin primarily focuses on its value as a computer science tool, including cryptography, blockchain, and reusable proof-of-work mechanisms, with the aim of using the Bitcoin protocol to strengthen cybersecurity and enhance military capabilities, which is still in the experimental stage. He also mentioned that maintaining the global dominance of the U.S. dollar aligns with U.S. military interests and gave a positive evaluation of the stablecoin legalization bill, the GENIUS Act, signed by Trump last summer, believing that the bill helps to solidify the global position of the dollar.

According to the official announcement, the prediction market Kalshi, regulated by the Commodity Futures Trading Commission (CFTC), has integrated Pyth as the contract settlement data source for its newly launched commodity center, covering markets such as gold, silver, Brent crude oil, natural gas, copper, corn, soybeans, and wheat.At the same time, Pyth Pro will provide direct market data access to Kalshi's market makers. Kalshi stated that this move aims to support the continuous trading and reliable settlement of commodity-related event contracts; Pyth Pro will subsequently expand to asset classes such as indices, stocks, and foreign exchange.

According to monitoring by the blockchain security firm SlowMist, MistEye has received threat intelligence from the community indicating that a malware named "MacSync Stealer" (v1.1.2) is active and highly destructive. This malware targets macOS users, stealing sensitive data including cryptocurrency wallets, browser credentials, system keychains, and infrastructure keys (SSH/AWS/K8s).The malware uses a spoofed AppleScript system dialog for phishing and displays fake error messages stating "unsupported" after data leakage. It has immediately synchronized this IOC (Indicator of Compromise) to clients. Do not execute unverified macOS scripts and remain highly vigilant against unexpected system password prompts. If an attack is suspected, immediate remediation is required: change all infrastructure credentials (SSH/AWS/K8s), invalidate any exposed keychains, and quickly migrate cryptocurrency assets to a secure wallet.

According to TRONSCAN data, the JST treasury address (TZJVQuU3CJqBScwoxhRtkxQ7JjsNNrpEag) continues to extract funds from protocol earnings and transfer them to the black hole address (T9yD14Nj9j7xAB4dbGeiX9h8unkKHxuWwb) for permanent destruction.As of now, the black hole address has cumulatively destroyed over 1.356 billion JST, accounting for 13.7% of the total supply. All operations are publicly traceable on-chain, and the ongoing deflation driven by real earnings is continuously strengthening the scarcity of JST, building long-term support for the token's value. This also marks a new phase of value growth for JST, driven by both intrinsic profits and a transparent mechanism.

The Coinbase Quantum Computing and Blockchain Independent Advisory Committee has released its first position paper stating that sufficiently powerful quantum computers may be able to crack the encryption mechanisms used by mainstream blockchains to protect digital assets in the future. However, such devices do not currently exist, and encrypted assets remain secure for now. The industry should begin preparing for quantum resistance upgrades starting now.The document points out that there are currently no substantial risks associated with Bitcoin mining, hash functions, and on-chain historical records; the main vulnerability lies in the digital signatures at the wallet layer. Ethereum has proposed a clearer migration roadmap, and Solana, Algorand, and Aptos have also begun to provide or plan quantum resistance solutions.

ChainCatcher reports live that Lily Liu, President of the Solana Foundation, delivered a keynote speech at the 2026 Hong Kong Web3 Carnival. She pointed out from a macroeconomic perspective that global production, users, and resources are distributed globally, but capital formation is not; only 20 stock exchanges in 14 countries account for 94% of the global market value of approximately $145 trillion, with two-thirds concentrated in the United States. This means that about 180 countries have almost no access to capital markets, and their economies can only rely on debt rather than equity financing, failing to provide ownership pathways for their citizens.She proposed the vision of an "Internet Capital Market," where any asset from anywhere can raise capital from anyone globally, priced in dollars and settled on an open track. Stablecoins are the key infrastructure for this vision, enabling any country to participate in the global financial system, while Solana provides the underlying settlement and execution layers. She also contrasted "Universal Basic Ownership" (UBO) with the widely discussed "Universal Basic Income" (UBI) in the AI era, arguing that blockchain allows anyone with a mobile phone to hold a part of their country's economy, representing basic property rights in the digital age without resorting to placing everyone in a welfare system.

According to Slow Fog CISO @im23pads's post on the X platform, Claude Desktop has been reported to secretly write a backdoor file into browsers. When users install the Claude Desktop application, it writes a special file to all Chromium-based browsers on the computer without the user's knowledge.This file acts as a pre-authorized backdoor, which, when used in conjunction with specific browser extensions, can gain complete control over the user's browser.

Glassnode's latest report indicates that although buying interest remains strong, providing some buffer for prices, market sentiment is turning cautious. Data shows that the cumulative volume delta (CVD) has shifted from positive to negative, selling pressure is rising, and bearish sentiment is beginning to emerge.Meanwhile, centralized exchanges are active, and market participation remains high. In the futures market, the increase in open interest indicates a rise in risk appetite, but the funding rate for long positions has significantly decreased, and the CVD for perpetual contracts has sharply declined, suggesting that traders are more willing to pay a premium to short, while buyer initiative is weakening and bearish sentiment is intensifying.In the options market, the demand for downside protection has decreased, which may ease bearish sentiment, but the contraction in open interest could indicate profit-taking, affecting subsequent volatility. The narrowing of volatility spreads suggests that market sentiment is shifting from risk pricing to neutral.The ETF sector has become a highlight, with the MVRV ratio and net inflows of U.S. spot ETFs rising, profitability and investor interest strengthening, and trading activity significantly increasing, indicating a growing enthusiasm for participating in Bitcoin through regulated channels, with market sentiment being cautiously optimistic.In terms of liquidity, the share of hot money has decreased, and the negative change in realized market value has narrowed, indicating that old money is dominating and net outflows are easing. The supply ratio between short-term and long-term holders remains stable, and long-term holders' confidence is solid.

According to CoinDesk, citing informed sources, Coinbase is collaborating with the cryptocurrency exchange platform Bybit to explore methods for tokenization, custody, and distribution of assets such as U.S. public and pre-IPO stocks.The informed source added that the ongoing discussions do not involve any form of equity acquisition or similar transactions. Bybit's plans to enter the U.S. market involve a new entity led by former co-CEO Helen Liu, working with a local partner providing licensing and compliance services whose identity has not been disclosed, rather than Coinbase.CoinDesk reported that both Bybit and Coinbase declined to comment.

According to Cointelegraph, Iran has designated Bitcoin for paying the oil transit fees in the Strait of Hormuz, but insiders say that most of the funds are still settled through stablecoins.Hamid Hosseini, spokesperson for the Iranian Oil, Gas and Petrochemical Products Exporters Union, stated that each tanker must report its cargo information to Iranian authorities via email, after which Iran will inform the amount of the fee to be paid, which must be paid in cryptocurrency. "Once the email arrives and Iran completes the assessment, the vessel will be given a few seconds to pay in Bitcoin, ensuring that it cannot be tracked or confiscated due to sanctions."

The Zcash Foundation tweeted that it has released version 4.3.1 of Zebra. This version includes several critical security fixes, and all node operators are advised to upgrade immediately. Additionally, this version introduces a Dockerized mining environment, automated checkpoint management, and several CI enhancement improvements.

According to The Block, Josh Stark, a key figure at the Ethereum Foundation (EF), announced his resignation after five years and will officially step down at the end of the month. Stark joined the Ethereum Foundation in 2019, initially working in the special projects team, and later rose to leadership, collaborating with EF Chair Aya Miyaguchi, Ethereum founder Vitalik Buterin, and co-executive directors Hsiao-Wei Wang and Bastian Aue.He is one of the most prominent members of the foundation's external image and has led several significant advancements in Ethereum, including the "The Merge" upgrade that transitioned from proof of work to proof of stake, as well as subsequent upgrades like Dencun, Fusaka, and Pectra. During last year's leadership adjustments at the foundation, he was appointed as the "co-manager" of the EF board and recently took on the role of co-chair of the "trillion-dollar security" initiative.Last month, Stark co-authored a strategic blog post on Ethereum with Josh Rudolf and Julian Ma, outlining Ethereum's latest scaling direction and its relationship with the Layer 2 ecosystem. Stark stated, "I haven't planned for the future yet; I just want to take a good rest and spend time with family and friends." This resignation occurs against the backdrop of ongoing changes at the Ethereum Foundation.Last year, the foundation underwent significant leadership adjustments, refocusing its strategic priorities on scaling the Ethereum mainnet and core cypherpunk values; Tomasz K. Stańczak also resigned from his co-executive director position at the end of February this year, having served for less than a year. On the same day, Trent Van Epps also announced his departure from EF to fully dedicate himself to Protocol Guild, the independent funding organization for Ethereum core developers that he founded.

Blockstream CEO Adam Back stated that Bitcoin should adopt an optional quantum-resistant upgrade scheme, rather than the mandatory freezing of tokens at risk from quantum threats proposed in BIP-361.The BIP-361 proposal suggests phasing out addresses vulnerable to quantum attacks over five years and ultimately freezing un-migrated tokens, including assets held by Satoshi Nakamoto. Google's latest research indicates that a superconducting qubit system may need fewer than 500,000 physical qubits to crack Bitcoin encryption in just a few minutes. Currently, about 6.9 million BTC are at risk from such threats. In response to the quantum threat, BitMEX Research proposed establishing a canary fund that would implement a full freeze only when expenditures occur from the relevant addresses.

According to official data, JST has burned 271 million $JST in this single instance, equivalent to a value of approximately 21.3 million USD, accounting for 2.74% of the current total supply. At the same time, the treasury reserves have exceeded the 100 million USD mark, providing a solid guarantee for the continued advancement of the subsequent deflation process. All funds for repurchase and destruction come from the actual income generated by the protocol, thereby establishing an automated deflationary closed loop driven by actual earnings, where repurchase and destruction operate continuously. This marks that $JST is steadily moving towards a sustainable, endogenous, and long-term viable economic model.
