What is blockchain?

The term blockchain is a form of distributed ledger technology: a powerful, secure means of holding information. All participants in a chain, from two individuals to thousands, hold the same ledger of information which is accessed from their computer or digital device. This can range from transactions to shift patterns, qualifications or clearance to enter a site.


Whenever an individual makes a change (amending a document, uploading a new document, verifying a task) that alteration is logged and time-stamped against that individual and the whole blockchain updates.


Different individuals can have different access levels to the system. Also, individuals can remove their own personal data from the blockchain, however an anonymised link to any alterations they made will remain. This means the distributed nature of the information held ensures the blockchain itself is secure and is also protected from illegal tampering. In short, blockchain provides an irrefutable record of actions that have occurred for the business or organisation that has established it.


This removes the need to rely on any individual intermediary or agent for the truth. The distributed structure of blockchain has security baked into it. Meaning trust shifts from people and institutions to technology, delivering the protection that businesses, their employees and service providers need.
