A Block chain is a distributed digital ledger. It records transactions in a series of blocks. It exists in multiple copies, spread over multiple computers, which are called anodes. The ledger is secure because every new block of transactions is linked again to previous blocks in such a way that tampering with it is practically impossible. As it is decentralized, it does not depend on any single entity (Eg:Bank) for safekeeping.
