Nonce

aka: number used only once

Simple definition of Nonce
  • Nonce, a "number only used once," refers to the number a blockchain miner needs to discover before solving for a block in the blockchain.
  • Once the miner solves the hash, they receive the block reward.
  • Miners open new blocks by generating a nonce that makes the hash they create less than the hash from the block they are validating.
