Abstract. A blockchain is essentially a distributed database of records or public ledger of all transactions or digital events that have been executed and shared among participating parties. A distributed ledger is maintained by a group of computers called "nodes". Distributed ledger technology allows the participants of a distributed system to agree on a common view of the system, to track changes in the system, in a reliable way. Distributed ledger technology (DLT) is a digital system for recording the transaction of assets in which the transactions and their details are recorded in multiple places at the same time. DLT may also present new challenges and potential risks.
