Abstract
A digital database or ledger that is distributed among the nodes of a peer-to-peer network is blockchain. Bitcoin cryptocurrency (BTC), a virtual currency designed to act as money and a form of payment outside the control of any one person, group, or entity, and thus removing the need for third-party involvement in financial transactions, lays the foundation for blockchain technology. A blockchain is a distributed database or ledger shared among a computer network’s nodes. They are best known for their crucial role in cryptocurrency systems for maintaining a secure and decentralised record of transactions, but they are not limited to cryptocurrency use and are expected to be used in many other fields, like banking, voting, health care, and property records. Blockchain technology achieves decentralised security and trust in several ways, but challenges are still awaited in scalability and security. This paper includes an overview of blockchain architecture and a comparison of some typical consensus algorithms used in different blockchains. It concludes with future trends for blockchain, technical challenges and advancements are discussed briefly.
