Blockchain the underlying technology behind crypto-currencies is a digital ledger that records transactions among various participants via a peer to peer distributed network’. The primary feature setting it apart from other payment systems is that it keeps a permanent public record of all transactions since its inception, verified through a decentralized user consensus system. From an audit perspective, it could be a revolutionary tool
A cryptocurrency, crypto-currency, crypto, or coin is a digital currency designed to work as a medium of exchange through a computer network that is not reliant on any central authority, such as a government or bank, to uphold or maintain it.
A blockchain network usually consists of specific agents with each
transaction verified by an agreement among the majority of the agents.
Unlike a traditional database, the data on the chain are permanently
stored and cannot be erased once a transaction enters the system. To
maintain a cumulatively added ledger in a blockchain network, cryp-
tography is used to record transactions among the participating agents of
the same network.
