What is blockchain ?
Blockchain is a kind of database that records transactions in a public ledger without requiring verification from a third party. Distributed on a peer-to-peer network, it is made up of data chunks that are joined to create an unbroken chain of unchangeable records. To prevent a single point of failure, every computer connected to the network keeps a copy of the ledger. Blocks are permanently added in a tamper-proof manner in sequential succession.
