Linked timestamping

Linked timestamping is a way to prove that something existed at a certain point in time. It works by using a network of computers to create a record (called a ‘blockchain’) that shows when something was created, updated, or changed. This blockchain can be used to prove when things exist. For example, if you needed to prove that you wrote a blog post on a certain day, you could get it ‘timestamped’ by having that record added to the blockchain. That way, it would be easy to prove that you wrote something at a certain time.
