ChainCatcher news, Ethereum founder Vitalik Buterin published a long article titled "d/acc: one year later," reflecting on the development of the d/acc (decentralized acceleration) concept proposed last year. The article focuses on three key issues: AI safety regulation, the role of cryptocurrency in d/acc, and public goods financing.Vitalik proposed two major strategies for AI safety: first, establishing accountability by setting reasonable legal responsibilities for AI users, deployers, and developers; second, implementing a global "soft pause" mechanism at the industrial hardware level, which can reduce global computing power by 90-99% if necessary. Vitalik stated that d/acc has three major connections with cryptocurrency: the extension of values, the early adopter community, and technological complementarity. In particular, the contributions of the crypto community in areas such as prediction markets and zero-knowledge proofs. The article also mentions innovative mechanisms including quadratic funding, retroactive public goods funding, and deep funding, emphasizing the importance of decentralized financing in promoting the development of open-source projects. Vitalik believes that despite the current challenges of rapid technological development and reduced global cooperation, new tools such as AI and biotechnology provide humanity with the capability to address these challenges.
