Linked timestamping is a cryptographic technique used to verify the existence and integrity of data at a specific point in time. It involves creating a chain of timestamps that are linked together in such a way that each timestamp reinforces the validity of its predecessors. This can be particularly useful in scenarios such as digital document verification, blockchain technology, and maintaining a secure history of transactions.
