Solana community proposal aims to remove durable Nonce, requiring transactions to include a recent blockhash

Odaily: The Solana community has issued a proposal to remove durable Nonce, requiring every transaction to include a recent blockhash for replay protection, and plans to disable the system program instructions used to initialize, advance, and upgrade Nonce accounts. The plan is expected to be activated on mainnet no earlier than May 5, 2027, to allow migration time.
