SIMD-0401: p-stake, a Pinocchio rewrite of the Stake program logoSIMD-0401: p-stake, a Pinocchio rewrite of the Stake program
Still open. Last updated 4 Nov 2026. Not live. Keep the SPL Stake Pool piece.
devrels.xyz/a/387SIMD-0401 proposes replacing the native Stake program Stake11111111111111111111111111111111111111 with a compute-optimized Pinocchio rewrite called p-stake. Pull request solana-improvement-documents#401 is still open. Last updated 4 Nov 2026. Title: Stake program Pinocchio migration. X @SolanaFndn.
The current program lives at solana-program/stake. The SIMD file in the PR is proposals/0393-stake-program-pinocchio-migration.md. Stake pools, LST protocols, and wallets that split or merge stake would feel any CU drop on those instructions. This SIMD is a proposal, not a mainnet cutover. Keep SPL Stake Pool.
