Vitalik Links AI Safety to Governance Theory Ethereum co-founder Vitalik Buterin (@VitalikButerin) says adversarial governance theory could offer new tools for AI safety. He argues governance and AI safety share a similar principal agent problem. In both cases, less capable overseers must control more sophisticated agents. According to Buterin, mechanisms of design can be helpful in limiting exploitation by AI of human rules. Furthermore, he emphasizes the possibility of collusion for both governance and AI systems.

Vitalik Bets Against AI Breaking Bitcoin Security Ethereum co-founder Vitalik Buterin (@VitalikButerin) has rejected a prediction that AI could seriously undermine Bitcoin’s bitcoin:native security. The prediction argues Bitcoin could lose more than 50% of its value within two years. Vitalik said he takes the opposite side and remains optimistic about long term cybersecurity. He expects Bitcoin to handle network level attacks without requiring social consensus. Vitalik also said he considers actual breaks in hashing or Proof of Work highly unlikely.

Vitalik Buterin Says Ethereum Scaling Can Draw Lessons From Bitcoin’s Utreexo Vitalik Buterin said the Bitcoin community deserves credit for work on technologies such as Utreexo, adding that Ethereum’s current scaling proposals are exploring similar ideas. The goal is to support a spectrum of state models, ranging from UTXO-like state to dynamic state, so that most Ethereum activity can scale substantially without significantly compromising decentralization, ease of running nodes, or censorship resistance.

Vitalik Backs EF Layoffs, Citing Promising Transition Vitalik Buterin (@VitalikButerin) announced that the Ethereum Foundation (@ethereumfndn) is reducing its budget by roughly 40% this year. The move follows last year’s Treasury Management Policy, shifting the EF from spending about 15% of its funds annually to a long-term endowment model targeting just 5% per year after 2030. He openly acknowledged the human cost, praising the brilliant, dedicated engineers, some with nearly a decade of protocol work, who are leaving. Rather than claiming painless efficiency gains, Vitalik detailed deliberate strategic sacrifices to sustain ambitious progress. In the meantime, the EF will continue the Ethereum Strawmap, its third major iteration covering consensus, proofs, privacy, and more, while expanding its Access Layer role.
