Blockchain is the future , here is how you can use it .
A blockchain is a continuously growing list of records, called blocks, which are linked and secured using cryptography.Each block typically contains a cryptographic hash of the previous block,a timestamp and transaction data.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."managed by a peer-to-peer network collectively adhering to a protocol for validating new blocks. Once recorded, the data in any given block cannot be altered retroactively without the alteration of all subsequent blocks, which requires collusion of the network majority.
