Blockchain database differs from a typical database in the way it stores data i.e., in blocks which are chained together. New data is appended to the chain as a fresh block in chronological order. Once a block is added, it cannot be deleted or revered, which is a key feature of Blockchain. The transactions are decentralized so that control of the database does not rest with a single entity, but all users retain control.
Blockchain technology can be used to create a permanent, public, transparent ledger systems for compiling business data, such as sales, tracking digital use, payments, cryptocurrencies, etc.
