Tech Headlines
1. Ethereum Co-Founder Vitalik: Ethereum Will Continue to Implement Multiple "Hard Rules" to Enhance Security and Protocol Efficiency
https://foresightnews.pro/news/h5Detail/91868
Ethereum co-founder Vitalik Buterin posted on X that in recent years, Ethereum has effectively enhanced protocol security and long-term adaptability by continuously introducing multiple "hard rules." In 2021: EIP-2929 and EIP-3529 increased storage read costs and reduced gas refunds; in 2024: alongside the Dencun upgrade, the contract self-destruct instruction was weakened; in 2025: a gas limit of 16,777,216 will be set per transaction. These changes establish clear upper bounds on the maximum processing capacity per block and per transaction, helping to prevent various types of denial-of-service attacks, simplifying client implementations, and creating more room to improve system efficiency. More hard limits are expected to be introduced going forward, including: limiting the total byte size of accessible code (short-term increase in cost for calling large contracts, medium-term adoption of a binary tree structure and per-chunk data billing); setting a maximum computation cycle limit for zero-knowledge EVM verifiers with corresponding cost adjustments; and revising memory pricing mechanisms to establish a clearer upper bound on EVM maximum memory consumption.

According to Anthropic's cutting-edge red-teaming test results, AI agents identified multiple smart contract vulnerabilities in a simulated blockchain environment, with a potential exploit value of up to $4.6 million. The test covered the full workflow—including contract analysis, command-line tool configuration, network reconstruction, exploit generation and validation—and was accompanied by the release of a new benchmark for smart contract security evaluation. This research was jointly conducted by Anthropic, the MATS program, and the Fellows initiative.

Swiss fintech company Mt Pelerin has announced the launch of a personal cryptocurrency IBAN service. This service allows users to convert self-custodial wallets into universal accounts, enabling seamless fund transfers between blockchain and traditional banking networks. Users can create a personal EUR or CHF IBAN linked to their crypto wallet, supporting receipt of bank transfers and direct conversion into cryptocurrency deposited into the wallet, as well as sending bank transfers to anyone using cryptocurrency held in the wallet. These payments appear identical to standard bank transfers, while cryptocurrency settlement occurs seamlessly in the background. The service is open to global users (excluding those in restricted countries), with IBANs provided free of charge, free conversion between fiat and ZCHF stablecoin, and standard fees applied for conversions involving other cryptocurrencies. The service supports over 30 cryptocurrencies across 15 blockchains.
Industry Dynamics

Russian Deputy Finance Minister Ivan Chebeskov told local media that financial authorities are prepared to abandon exclusive regulatory definitions that previously allowed only a small group of "highly qualified" investors to access cryptocurrencies such as Bitcoin and its derivatives. The Bank of Russia now considers it "possible" to ease current regulations restricting cryptocurrency transactions within sanctioned countries, and monetary authorities are discussing the matter with the Ministry of Finance. Under sanctions pressure, Russian financial regulators are shifting their stance on cryptocurrency.
2. UK's New Legislation: Cryptocurrencies Are Included in the "Personal Property" Protection Framework

The UK has formally passed a bill recognizing digital assets, including cryptocurrencies and stablecoins, as "property," a move advocates say will provide stronger legal protection for crypto users. On Tuesday, Lord Speaker of the House of Lords John McFall stated that the Property (Digital Assets etc) Bill has received Royal Assent—the formal approval of King Charles III—and has now officially become law. Freddie New, Policy Director at Bitcoin advocacy group Bitcoin Policy UK, posted on X that the bill "becoming law is a huge step forward for Bitcoin’s development in the UK and great news for everyone holding and using Bitcoin in the country." In the UK, the common law system—developed through judicial precedent—had previously recognized digital assets as property, but this bill aims to formally codify that principle into statute and implement the 2024 recommendation by the Law Commission of England and Wales to explicitly define crypto assets as a new category of personal property rights, thereby enhancing legal clarity.
3. Italy Has Ordered an In-Depth Review of Its Current Cryptocurrency Risk Mitigation Measures

In a statement, the regulators said: "We have launched an in-depth review of whether the current safeguards for retail investors’ direct and indirect investments in crypto-assets are adequate."
