A continuously list of growing records, called Blocks, which are linked and secured using cryptography. An open distributed ledger that can record transactions efficiently, in a verifiable and permanent way.
BlockChains are secure by design – a distributed computing system. By storing data across its network, the Bockchain eliminates risks by data being stored or held centrally. This makes it suitable for BlockChains to record events, transaction processing, voting, food traceability, identity management etc.
