A blockchain , [1] [2] [3] originally block chain , [4] [5] is a growing list of records , called blocks , which are linked using cryptography . [1] [6] Each block contains a cryptographic hash of the previous block, [6] a timestamp , and transaction data (generally represented as a merkle tree root hash).

A blockchain , [1] [2] [3] originally block chain , [4] [5] is a continuously growing list of records , called blocks , which are linked and secured using cryptography . [1] [6] Each block typically contains a cryptographic hash pointer as a link to a previous block, [6] a timestamp and transaction data. [7] By design, blockchains are inherently resistant to modification of the data. The Harvard Business Review describes it as "an open, distributed ledger that can record transactions between two parties efficiently and in a verifiable and permanent way." [8] For use as a distributed ledger, a blockchain is typically managed by a peer-to-peer network collectively adhering to a protocol for validating new blocks. Once recorded, the data in any given block cannot be altered retroactively without the alteration of all subsequent blocks, which requires collusion of the network majority. |

A blockchain [1] [2] [3] — originally block chain [4] [5] — is a distributed database that maintains a continuously-growing list of ordered records called blocks . Each block contains a timestamp and a link to a previous block. [6] : 6 By design blockchains are inherently resistant to modification of the data — once recorded, the data in a block cannot be altered retroactively. |

A block chain or blockchain is a permissionless distributed database based on the bitcoin protocol [1] that maintains a continuously growing list of transactional data records hardened against tampering and revision, even by operators of the data store's nodes . The initial and most widely known application of the block chain technology is the public ledger of transactions for bitcoin [2] which would become the inspiration for similar implementations often known as altchains.
