Abstract
Techniques for updating blockchains using a proof of work determined serially include receiving a block of data for inclusion in a new block of a blockchain; deterministically determining an initial nonce, hashing a combination of the block of data and the initial nonce to create a hashed value; iteratively deterministically determining an updated nonce based on a combination of the hashed value and updating the hashed value by hashing the updated nonce until the updated hashed value satisfies a proof of work criteria; creating the new block based on the block of data, the initial nonce, and the updated hashed value that satisfies the proof of work criteria; and having the new block stored in the blockchain.
