  Mixhash is a hash of the index, nonce, content, and previous node’s hash. This is unique, non-reversible, and of fixed length. It serves to encrypt the data of a particular block.

  Nonce stands for the Number used only once. It is a unique whole number that shall be used only once in the blockchain. The purpose of this number is to make the hash of the current cell conform to a certain standard as is set by the blockchain. The mining of the nonce represents the Proof of Work that miners display in order to get the block reward.

  Used in tandem, these values are instrumental in providing the resistance to the mutation that the concept of blockchain is known for.
