The nonce is the number that blockchain miners are solving for. When the solution is found, the blockchain miners are offered cryptocurrency in exchange. The blockchain is the cornerstone of cryptocurrency. This is done by processing the block input through a function, which produces an output of a fixed length. The function used to generate the hash is deterministic, meaning that it will produce the same result each time the same input is used. It also means that the function can generate a hashed input efficiently, it makes determining the input difficult leading to mining , and makes small changes to the input result in a very different hash. This complex system creates the privacy net of blockchain. Adding transactions to the blockchain requires substantial computer processing power.

In cryptography , a nonce is an arbitrary number that can be used just once in a cryptographic communication. It is similar in spirit to a nonce word , hence the name. It is often a random or pseudo-random number issued in an authentication protocol to ensure that old communications cannot be reused in replay attacks. They can also be useful as initialisation vectors and in cryptographic hash functions. A nonce is an arbitrary number used only once in a cryptographic communication, in the spirit of a nonce word. They are often random or pseudo-random numbers.
