Nonce

A nonce is a random or unique number used only once in cryptographic processes. In blockchain mining, the nonce is utilised until the resulting hash, when combined with the block data, meets the network’s certain difficulty criteria. This process is Proof of Work (PoW) and makes each block unique and secure. Once a valid nonce is found, the block is added to the blockchain. Nonces are vital for blockchain security, ensuring fairness and decentralisation.
