Blockchain is a “chain of blocks of data”, a manner of recording information in a database (e.g. transaction data), in the form of subsequent blocks. Each block contains a reference to the previous block, making the chain unbreakable. The database is shared via a public or private computer network.

Each computer node within the network stores a copy of the database, so there is no single failure point. Each piece of information is mathematically encrypted before it is added to the chain of historical records as a new block.

Hence, transactions in the blockchain are irreversible and fully secured. It is impossible to make any changes to historical data due to the fact that the same copies of the whole chain are stored on different servers distributed around the network. The history of the records in a blockchain technology-based database can be viewed and verified, which enables auditing and builds up trust.
