Vitalik Buterin Proposes Binary State Trees and RISC-V Upgrade to Overhaul Ethereum’s Execution Layer

TLDR: EIP-7864 proposes replacing Ethereum’s hexary keccak tree with a binary structure, cutting Merkle branch size by 75%. Blake3 and Poseidon hash functions could accelerate Ethereum’s proving efficiency by up to 100x over the current keccak setup. Replacing the EVM with RISC-V would reduce a ZK prover translation layer, cutting the protocol’s proving bottleneck by [...]
