Nonce

Nonce refers to a random or arbitrary number used in cryptography and blockchain mining to solve mathematical puzzles and generate a proof-of-work. In the context of blockchain, miners repeatedly change the nonce value in a block's header until they find a hash value that meets a specific requirement, such as a certain number of leading zeros. The nonce serves as a variable input in the mining process, allowing miners to create a valid block hash that satisfies the difficulty level set by the network.
