ABSTRACT
Blockchain is at present one of the most disruptive technologies that have the potential to radically change today’s business models. Blockchain is a decentralised database distributed across several systems. Blockchain technology is expected to be used by different sectors, such as finance, government, and healthcare domains. Blockchain is basically a peer-to-peer cryptographic-based mechanism where each peer holds a digital database known as a ledger in some applications. A smart contract is used in the blockchain framework in order to execute some actions when certain predefined conditions in the contract are met. Public blockchain means that everyone can join and contribute to the network. Blockchain holds the total value of daily exchanges. The central bank can examine the enormous information that is stored in the blockchain. Multi-signature provides a way to form contracts without trusting any other party in the blockchain.
