A '''blockchain''' — originally '''[[block chain]]''' — 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. By design blockchains are inherently resistant to modification of the [[data]] — once recorded, the data in a block cannot be altered retroactively.

Blockchains are secure by design and an example of a distributed computing system with high [[byzantine fault tolerance]]. Decentralised consensus can therefore be achieved with a blockchain. This makes blockchains suitable for the recording of events, title, medical records and other records management activities, identity management, transaction processing and proving provenance. This offers the potential of [[mass disintermediation]] and vast repercussions for how global trade is conducted.

Blockchain is one of the key technologies of [[Smart contract]]s.
