Block Chain : A Practical Guide To Developing Business, Law And Technology Solutions Blockchain is a decentralized digital ledger technology that allows multiple parties to record and verify transactions in a secure and transparent manner. It was originally introduced as the underlying technology for Bitcoin, the first cryptocurrency, but its applications have since expanded beyond digital currencies.
