A blockchain is a data structure that makes it possible to create a digital ledger of transactions and share it among a distributed network of computers. It uses cryptography to allow each participant on the network to manipulate the ledger in a secure way without the need for a central authority.
The “currency” of blockchain is bitcoin – a term that has both its supporters and critics. But a movement toward embracing digital currency, throughout the world banking community at least, seems to be taking hold.
