Blockchain architecture is based on distributed and decentralised technology used to store transaction records in blocks [1].These blocks are linked to each other based on the value of the hash address (previous hash) generated through a cryptographic mechanism [2].Blockchain technology has developed as an open ledger to record transactions in a distributed manner.New blocks will be created after the mining process is complete through the protocol consensus that requires each peer to verify transactions [3][4][5].
