Digital Identity Using Blockchain: A Review
Jitendra B. Kapade, Rakesh S Deore · 2025
An immutable ledger that is kept in a dispersed network of peers that are not trusting one another is known as a blockchain. It is used to record transactions in a verifiable and permanent manner. A copy of the ledger is kept by each peer. To validate transactions, the peers use a consensus mechanism. They then organise the transactions into blocks and create a hash chain over the blocks. As required for consistency, this procedure arranges the transactions to create the ledger. For his well-known creation of digital cash, or crypto- currency, such as Bitcoin, Satoshi Nakamoto (presumed pseudonymous person or persons) developed Blockchain technology. Bitcoin's double spending issue was resolved by Nakamoto using Blockchain technology, but this innovative technology quickly found use in a wide range of other applications. Governments around the globe are some of the entities that are leading the digital transformation through digital identity. The adoption of Blockchain technology for digital identity solutions helps to empower citizens and build a more connected digital society. This Paper reviews the use of digital identity using Blockchain Technology.
