Nonce is the central part of this Proof of Work. The Nonce is a random whole number, which is a 32-bit (4 byte) field, which is adjusted by the miners, so that it becomes a valid number to be used for hashing the value of block. Nonce is the number which can be used only once. Once the perfect Nonce is found, it is added to the hashed block.

What is a Blockchain Nonce? Nonce, short for “number used once”, is a random number that can only be used one time. Nonces are generated for a specific use, most often to modify the result of a function in a cryptographic communication. Typically, a nonce is a number that varies with time, in order to ensure that some values cannot be reused.
