A blockchain is a database that is in a distributed form that is shared by different nodes of any computer network. Similar to databases, a blockchain stores data electronically using digital formats. Blockchains are very popular for their work in cryptocurrency systems like Bitcoin, for the maintenance of secure and decentralized records of any transaction done. The significance of blockchain technologies is it provides enhanced security and fidelity that produces trust among clients without any trusted third party.
The basic difference between blockchain and general databases is the structure of data used in them. The information collected in the case of blockchain is the grouped data which are known as blocks. These blocks have certain fixed storage space and when this space is filled blocks are closed and are attached to previous blocks in the structure, forming a chain known as the blockchain. All the newly collected information is stored in a newly formed block and compiled to the parent chain once filled and closed.
The main motive of blockchain is to allow digital information to be recorded, stored, and distributed but not manipulated. This is the foundation for immutable ledgers or proof of transactions that cannot be deleted, altered, or destroyed by any means. Due to this reason, blockchains are known as DLT (Distributed Ledger Technology).
