Vitalik Buterin, co-founder of Ethereum, stated in a post on X platform that the Ethereum team has been performing very well this year, making contributions in various aspects to ensure the long-term scalability, decentralization, and resilience of Ethereum. All of these ideas are expected to achieve key milestones on the short-term expansion roadmap and be ready for implementation. According to Vitalik Buterin's retweeted tweet, Ethereum developers have proposed a minimal zkVM "leanVM" for slimming down Ethereum, optimized for XMSS aggregation and recursion. Compared to Cairo, leanVM significantly reduces commitment costs with a four-instruction ISA, multilinear STARK, and logup* for maximum efficiency.
