  31. 31. Process • A transaction is transformed into a hash. • The hash of a whole block is created. • A nonce (random string) is appended to the hash and hashed again. • The resulting hash is compared to the difficulty level required by a blockchain. • If it is less than the difficulty level, other nodes on the network checks and confirms the solution and updates their instances of the blockchain. • If it not, then the nonce is changed and the trial-and-error process repeats. • The hash of the header becomes the new block’s identifying string, and the addition is propagated through the network. That block is now part of the ledger. • The miners responsible for this are rewarded (if there is a reward associated with mining).
