A blockchain is a linked list of immutable tamper-proof blocks, which is stored at each participating node. Each block records a set of transactions and the associated metadata. Blockchain transactions act on the identical ledger data stored at each node. Blockchain was first perceived by Satoshi Nakamoto, as a peer-to-peer money exchange system. Nakamoto referred to the transactional tokens exchanged among clients in his system as Bitcoins.
