Blockchain is a system of recording information in a way that makes it difficult or impossible to
hack, change or cheat the system. A blockchain is essentially a digital ledger of transactions that is distributes across the entire network of computer systems on the blockchain. Each block in the chain contains a number of transactions, and every time a new transaction occurs on the blockchain, a record of that transaction is added to every participant’s ledger. The decentralized database managed by multiple participants is known as Distributed Ledger Technology (DLT).
