**[Anza: Solana Core Protocol to Gradually Remove Floating-Point Operations to Avoid Consensus Divergence Risks]** The Solana core client development team, Anza, has announced that it is gradually removing floating-point operations from the Solana core protocol. The first phase, SIMD-0391, has been activated on the Mainnet Beta at epoch 1026, replacing floating-point operations in the warm-up and cool-down logic of the Stake Program and validator client with fixed-point operations. The second phase, SIMD-0607, has been proposed and is under review, targeting the runtime itself to remove floating-point operations from the inflation rewards and rent calculation paths. Anza stated that floating-point operations may produce different rounding results on different hardware, validator clients, and compilers, potentially leading to consensus divergence and network liveness risks. These two improvements eliminate such risks by standardizing fixed-point operations. Further steps will address floating-point operations in other paths.
