On Monday, Ethereum co‑founder Vitalik Buterin argued that most existing DAOs function only as token‑voting treasuries and need to be redesigned for critical infrastructure such as oracles and onchain dispute resolution. He suggested different DAO models for "convex" and "concave" governance problems, emphasized privacy tools like zero‑knowledge proofs and warned that DAO governance should use but not be controlled by AI. He added that teams building new oracles or governance layers should treat DAO design and communication as a core part of their work amid a DAO token market capitalization of at least $17.5 billion.

On Jan. 1, 2026, China permitted commercial banks to pay interest on e‑CNY wallet balances, aiming to integrate the CBDC into bank balance sheets.
