The BriefVitalik Buterin overlaid his 2023 Ethereum roadmap onto the live Strawmap and found the priorities have shifted more than public roadmap talk let on. Buterin wrote the construction already implies exposing users to an instruction set that is not the EVM, Ethereum’s virtual machine, with leanISA and RISC-V the leading candidates. New state types are not a rebrand of the old state-expiry plan, Buterin wrote. Two questions remain open: which instruction set, leanISA or RISC-V, ultimately wins, and how soon the zkzk frame proposal advances past discussion on Ethereum Magicians. EVM The Ethereum Virtual Machine is the runtime environment that executes smart-contract bytecode across every Ethereum node, using a 256-bit stack architecture and gas-metered computation.
