It differs from a typical database in the way it stores information; blockchains store data in blocks that are then chained together.

Distributed – blockchain is inherently multi-locational data structures and any user can keep his or her own copy, thus providing resilience and robustness; Ledger – blockchain is immutable, once a transaction is written it cannot be erased and, along with multiple copies, this means that the ledger’s integrity can easily be proven.

Blockchain defined: Blockchain is a shared, immutable ledger that facilitates the process of recording transactions and tracking assets in a business network.An asset can be tangible (a house, car, cash, land) or intangible (intellectual property, patents, copyrights, branding).

Blockchain’s role as a dual-pronged change agent — as a new form of infrastructure and as a new way to digitise assets through tokens, including cryptocurrency — is not easy to explain. Think about other new technologies: users can try on virtual reality goggles or watch a drone take flight. But blockchain is abstract, technical and A blockchain, originally block chain, is a growing list of records, called blocks, that are linked using cryptography. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data (generally represented as a Merkle tree).By design, a blockchain is resistant to modification of its data. This is because once recorded, the data in any given block cannot be Jun 12, 2017 clearing, settlement and related activities.
