Transaction Nonce
Also known as: Nonce, Transaction Counter
A unique number assigned to each transaction to enforce order and prevent duplication.
A Transaction Nonce is a sequential number assigned to every transaction sent from a blockchain account, most notably in Ethereum. It ensures that transactions are processed in the correct order and are not replayed or duplicated. Each new transaction must have a nonce exactly one greater than the previous one. Nonces are crucial for managing transaction queues, enabling retries, and preventing replay attacks in account-based blockchain models.
