Solana Community Releases Proposal to “Remove Persistent Nonces”

The Solana community formally proposed the “Remove Persistent Nonce” initiative on November 9, with three core components: (1) complete removal of the persistent nonce mechanism; (2) requiring all transactions to include the latest block hash to prevent replay attacks; and (3) deprecating all system program instructions related to nonce accounts—including initialization, advancement, and upgrade functions. The proposal is scheduled to go live on mainnet as early as May 5, 2027, providing users ample time to prepare for the migration.
