Ethereum co-founder Vitalik Buterin posted on the X platform, stating that AI-accelerated mathematical research may pose new security threats to existing cryptographic systems, especially lattice-based cryptographic schemes, including ML-DSA and fully homomorphic encryption (FHE). He believes that advancements in AI in the field of mathematics over the next two years could significantly undermine the practical security of lattice cryptography, and ECDSA may face the risk of being compromised sooner than expected.Vitalik pointed out that over the past year, the Ethereum Lean roadmap has gradually shifted towards pure hash cryptographic schemes, avoiding the use of lattice-based signatures and related zero-knowledge proof structures. He suggested prioritizing the use of hash cryptography whenever feasible and adopting more conservative security parameters for lattice cryptography; privacy protocols should avoid storing encrypted information directly on-chain, and multi-signature wallets should prioritize off-chain signature confirmations. Additionally, Vitalik advised users, when operationally convenient, to store funds in addresses that have not initiated transactions to reduce potential risks, but he does not recommend users immediately migrate assets on a large scale. He emphasized that the migration process itself also carries risks, and his own losses due to migration errors have even exceeded the losses from past hacking attacks.

Cryptography researcher Justin Drake posted on the X platform, calling for the blockchain industry to calmly plan a "bunker mode." He suggested that large holders move most of their funds to new addresses that have never signed transactions, with public keys still hidden behind hashes. Subsequently, each time a signature is made, the remaining funds should also be transferred to the new address.He believes that AI is driving rapid breakthroughs in the field of mathematics, and ECDSA could potentially be cracked by classical algorithms before the quantum computing "Q-Day," possibly occurring in months rather than years, allowing private keys to be recovered in about a week using large GPU clusters. Drake also emphasized that there is no need for panic and hasty migration, stating that Binance, Bitbank, Robinhood, Bitfinex, and Tether could take this opportunity to strengthen their cold wallets.

The Organization for Economic Co-operation and Development (OECD) stated that investments driven by artificial intelligence have helped the global economy perform slightly better than expected this year, but the impact of commodity price shocks caused by conflicts in the Middle East is expected to weigh on economic growth momentum in 2027.The OECD predicts that the global economic growth rate will rise to 3%, down from the 3.1% forecast in June. AI infrastructure spending has become an important pillar supporting economic resilience, but the global outlook remains affected by factors such as fluctuations in the energy market.

According to Jinshi reports, the OECD stated that if economic turmoil continues, central banks in various countries are expected to raise interest rates by 50 to 75 basis points.

The Google Quantum AI team pointed out in their latest blog post that most blockchain technologies and cryptocurrencies rely on the vulnerable ECDLP-256 protocol. Although viable solutions such as post-quantum cryptography (PQC) already exist, implementation takes time, and the urgency for action is increasing.Google has previously set a timeline for transitioning to quantum-resistant cryptography by 2029 and is collaborating with organizations such as Coinbase, the Stanford Blockchain Research Center, and the Ethereum Foundation to advance related work.

According to official news, Optimism has released the quantum-resistant roadmap for Superchain, with the core content announcing the gradual phasing out of externally owned accounts (EOA) based on ECDSA signatures over the next decade. The specific plan is that by January 2036, EOA transactions using ECDSA signatures on the OP mainnet and superchain will be deprecated, and all such accounts must delegate their key management to smart contract accounts that support post-quantum signatures.The roadmap covers both user and consensus levels. At the user level, account abstraction technology will be utilized, through standards like EIP - 7702, to gradually delegate signature authority from EOA to smart accounts capable of verifying post-quantum signatures. At the consensus level, L2 sequencers and batch submitters will migrate to post-quantum signatures, while also calling for Ethereum itself to establish a timeline to transition validators from BLS signatures and KZG commitments to post-quantum algorithms. The entire upgrade process will be coordinated through a hard fork, providing the ecosystem with a decade to achieve a smooth transition.

Zhao Changpeng stated during the Binance Square AMA live broadcast: "Early investors in meme coins also face certain risks, and subsequent buyers are also acting on their own research; this phenomenon does not require third-party intervention for the time being. A true meme coin project needs to have historical significance and 'anecdotal value,' but the ones that are truly valuable are very few, with a failure rate exceeding 90%. Investors need to take responsibility for their choices."

According to market news, Japan has officially implemented the OECD's Crypto Asset Reporting Framework (CARF) starting January 1, 2026. This is a new mechanism aimed at enabling tax authorities around the world to share information on crypto asset transactions.Japan decided to introduce this mechanism through tax reform, and the National Tax Agency published a user-oriented brochure before its implementation last December, while also advancing preparations to collect information through exchanges. Affected by the implementation of this system, the Japanese crypto exchange Coincheck sent a notification to all users on January 6, requesting them to submit information such as their "tax residence country." Other exchanges in Japan will also gradually advance their information collection procedures. Existing users who opened accounts before the end of 2025 must submit their information by December 31, 2026, while users who open accounts after January 1 of this year must complete the declaration during the account opening process. Failure to submit the above information within the specified deadline, or submitting false content, may result in penalties under the law.

The Crypto-Asset Reporting Framework (CARF), developed under the leadership of the Organisation for Economic Co-operation and Development (OECD), officially came into effect on January 1, 2026, covering the first batch of 48 countries and regions.The framework requires Crypto Asset Service Providers (CASPs) to disclose user transaction information to tax authorities and submit annual reporting, covering activities such as transactions, exchanges, and asset transfers, to promote global tax transparency and enhance cross-border data exchange. CARF aims to fill the regulatory gap in the digital asset sector within the existing Common Reporting Standard (CRS) and plans to initiate regular information exchange among member countries starting in 2027. All EU member states, the UK, Brazil, the Cayman Islands, and other regions will be the first to participate, while countries like Australia, Canada, Singapore, Switzerland, and the UAE are expected to join by 2028. The United States plans to connect to the system in 2029. The OECD stated that this framework brings crypto assets under tax regulatory standards comparable to those of the traditional financial system, significantly reducing the space for tax evasion using crypto assets.

According to Jinshi reports, the OECD expects the Federal Reserve to "gradually" lower the key interest rate to 3.25% to 3.5% by the end of 2026.

ChainCatcher news, according to Jinshi reports, the OECD expects the Federal Reserve to cut the key interest rate again in 2025 and to make two more cuts in early 2026.

ChainCatcher news, Paradigm CTO Georgios Konstantopoulos stated that a year of research found no significant breakthroughs in account abstraction, suggesting it should have been set as a native feature of Ethereum in its early years.Vitalik Buterin responded that full account abstraction has not been achieved, requiring ECDSA or intermediaries, with intermediaries relying on privacy risks and censorship resistance, while quantum security and privacy protocols still pose challenges.

ChainCatcher news, according to Business Standard, a senior official from the Indian Ministry of Finance revealed that India will implement the OECD's Crypto Asset Reporting Framework (CARF) starting from April 1, 2027, bringing the overseas cryptocurrency assets of its residents under tax regulation.He stated that India is expected to sign the Multilateral Competent Authority Agreement (MCAA) next year—this agreement is a global framework for the automatic exchange of tax information. The official clarified that although India signed the MCAA agreement for financial account information in 2015, a separate agreement under the CARF framework is still required for crypto assets. To ensure the deployment is completed before the 2027 deadline, relevant legislative amendments and system preparations have been fully initiated.

ChainCatcher news, according to Globenewswire, ECD Automotive Design (NASDAQ: ECDA), the world's largest Land Rover and Jaguar repair company, announced that it has signed a $500 million equity financing agreement with ECDA Bitcoin Reserve LLC (hereinafter referred to as "the financing"). The proceeds from this strategic financing will enable ECD to implement an innovative Bitcoin reserve strategy, positioning the company as a next-generation value storage asset and/or for supporting growth and general corporate purposes.These initiatives align with ECD's plans to attract the Bitcoin and broader digital asset communities, which have created significant wealth over the past decade and represent a priority customer base. The company plans to explore ways to help these customers diversify their digital assets into high-end real-world assets (RWA), such as classic cars.In the next twelve months, ECD will offer a $21,000 vehicle upgrade credit to the first 21 customers who purchase new cars using Bitcoin, which can be freely chosen by the customers.

ChainCatcher message, Ethereum founder Vitalik responds to X user Paolo Rebuffo's comments on Pectra's implementation of account abstraction, pointing out that the account abstraction process is currently only halfway complete. He stated that the ultimate goal is to make non-ECDSA (Elliptic Curve Digital Signature Algorithm) accounts the mainstream account type. These accounts include features such as multi-signature, key changes, quantum resistance, and privacy protocols. Recently, significant progress has been made in simplifying the 7701 standard to promote the realization of this goal.

ChainCatcher news, the Organization for Economic Co-operation and Development (OECD) report analyzes the reasons why tokenization has not become more widespread. It points out that although tokenization brings efficiency improvements, securities settlement enhancements, and innovation opportunities, it faces numerous challenges.The report mentions that the lack of a sufficient investor base is a major obstacle, leading to insufficient liquidity, which makes issuers cautious about tokenization. The issuance of sovereign bonds can help promote the development of tokenization, as seen in the case of Slovenia.At the same time, the OECD emphasizes that quasi-sovereign issuers, such as the World Bank and the European Investment Bank, are more active, but liquidity issues are often resolved through integration with traditional systems, which also undermines the potential advantages of tokenization.Another challenge is the "chicken or egg" problem of network effects; when network effects have not yet manifested, it is difficult to prove the value of investments. Additionally, many institutions face technical debt and lack the funds to upgrade to distributed ledger technology (DLT).

ChainCatcher news, the South Korean Ministry of Economy and Finance announced that at the 17th Global Forum of the Organisation for Economic Co-operation and Development (OECD), the Multilateral Competent Authority Agreement on the Crypto-Asset Reporting Framework (CARF MCAA) was officially signed.The CARF MCAA is an institution established by the OECD in 2009, aimed at implementing standards for international tax transparency and the exchange of tax information. A total of 48 countries, including South Korea, Germany, Japan, and France, participated in this agreement. The signatory countries will exchange information on crypto-asset transactions based on the automatic information exchange framework for crypto-assets jointly developed by the OECD and the G20.According to the agreement, the exchange of information between countries will be implemented through separate negotiations among the signatory countries. The Ministry of Economy and Finance plans to amend relevant domestic laws starting in 2027 to facilitate the exchange of information on crypto-asset transactions and promote individual agreements.A relevant official from the Ministry of Economy and Finance stated, "Through this agreement, detailed information on crypto-asset transactions can be obtained, which will help enhance the transparency of the tax base related to crypto-asset income."

ChainCatcher message, Ethereum founder Vitalik posted on X: "Quantum computing is the biggest driving force. Whether we like it or not, externally owned accounts (EOA) will eventually disappear in the future, as quantum computing will ultimately break ECDSA."
