Vitalik Buterin: AI may weaken cryptography within two years and put ECDSA at risk, suggesting a priority on hash cryptography

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.

WasabiCard launched various AI subscription cards, covering payment scenarios for mainstream AI tools such as OpenAI and Claude

According to official news, WasabiCard has launched various AI subscription cards, catering to the global AI tool subscription and payment needs of enterprises and teams, supporting subscription payment scenarios for mainstream AI applications such as OpenAI and Claude. Through card-based payment solutions, companies can handle the procurement and expense management of AI services for different teams, projects, or business lines more flexibly.In addition to AI subscription payments, WasabiCard also supports bulk card issuance for enterprises, fund budget management, and multi-currency account setup, as well as various scenarios such as advertising, business travel, payroll, and e-commerce subscriptions. It helps companies configure payment permissions and budget limits by department, employee, or specific purpose, enhancing the management efficiency of AI-related expenditures and the transparency of fund usage.As AI tools gradually enter daily workflows in research and development, content production, customer service, and operations, cross-border subscription payments and expense management are becoming important infrastructure for global operations of enterprises. It is important to note that currently, WasabiCard-related products are not open for application to enterprises and individual users in mainland China.
