Solana community releases proposal to 'remove durable Nonce'

November 9: The Solana community has released a proposal to "remove durable Nonce." The proposal includes removing durable Nonce, requiring each transaction to include a recent block hash for replay protection, and disabling system program instructions used to initialize, advance, and upgrade Nonce accounts.

The related plan is expected to activate on mainnet no earlier than May 5, 2027, to allow users time to migrate.
