Blockchain (BC) gives the ability to store all history of any transaction. It is a continuously growing list of records, which are linked and secured using PKI cryptography. Each block typically contains a cryptographic hash of the previous block, transaction data and a timestamp.
By design, a blockchain is inherently resistant to modification of the data. It is “an open, distributed ledger that can record transactions between two parties efficiently and in a verifiable and permanent way”. It is suitable for the recording of events, medical records, food traceability, voting and many more.
