A number that is used only once within a specific operation to ensure the uniqueness of data. In crypto, it is used in different contexts, for example:
1. Mining: a variable value that is substituted into the hash calculation in order to find a new block in mining. Miners have to recalculate the hash many times, changing the nonce value until a valid result is found. This requires significant computational resources, which is the basis of the Proof-of-Work mechanism.
2. Transactions: a transaction number associated with a specific address. It is used to maintain the correct order of transactions and to protect against sending the same transaction more than once.
