It is a type of distributed ledger technology (DLT), a digital system for recording transactions and related data in multiple places at the same time.
Simply so,What is blockchain technology in simple terms?
Blockchain is a system of recording information in a way that makes it difficult or impossible to change, hack, or cheat the system. A blockchain is essentially a digital ledger of transactions that is duplicated and distributed across the entire network of computer systems on the blockchain.
Additionally,What is blockchain technology with example?
