Nonce
Advanced programming[1]
In cryptography, a nonce is an arbitrary number that can be used just once in a cryptographic communication. [2]
A nonce is an abbreviation for "number only used once," which is a number added to a hashed—or encrypted—block in a blockchain that, when rehashed, meets the difficulty level restrictions. The nonce is the number that blockchain miners are solving for.[3]
A miner will take a block of unconfirmed transactions from the transaction pool, choose a nonce, and if the resulting hash meets the target threshold then the miner will broadcast the block as solved.
