Blockchain Glossary Definition

A blockchain is an expanding list of cryptographically signed, irrevocable transactional records shared by all participants in a network. Each record contains a time stamp and reference links to previous transactions. With this information, anyone with access rights can trace back a transactional event, at any point in its history, belonging to any participant. A blockchain is one architectural design of the broader concept of distributed ledgers.

In web, data, cloud, and DevOps environments, this term helps teams describe application infrastructure, data flow, deployment practices, integration points, or operational tooling. It is relevant to how systems are built, hosted, versioned, monitored, and maintained.
