Blockchain is a technology that is known to store transactional records, simply known as ‘blocks’. The blocks are present in various databases which we call ‘chain’ and the network of block and chain is connected via peer-to-peer nodes. The complete storage phenomenon is called a digital ledger. Each transaction that a user makes in the ledger gets authorised by an owner as a digital signature. This helps in the authentication of the transaction and also prevents it from tampering. Therefore, the information contained in the digital ledger is very secure. In this article, you’ll learn about what a blockchain actually is, types of blockchain architectures, Components of a blockchain architecture, etc.
