Electronics Nuclear engineering Blockchain related technology nowadays involves cryptocurrency, supply chains, global trades, land registration, and logistics. While blockchain's unique characteristics provides benefits such as increase transparency, integrity and security of data that is shared across the network, employing blockchain requires very high energy consumption due to its mining process. Mining process’s high energy consumption was due to the Proof of work (PoW) consensus protocols on the blockchain network which utilizing the double SHA-256 algorithm to compute the hash of the block header.
