Proof of Existence is a method used to verify that a certain document or piece of information existed at a specific time. It leverages blockchain technology to create a permanent, tamper-proof record.

This process typically involves hashing the document, which creates a unique string of characters. This hash is then recorded on a blockchain. Because the blockchain is public and immutable, anyone can confirm that the document existed without revealing its content.

The main advantage of Proof of Existence is that it prevents disputes about the originality or existence of a document. It can be applied to various types of files, such as contracts, artworks, or even personal records.

By utilizing this method, individuals and organizations can provide undeniable proof of ownership or authorship. This can be particularly useful in legal matters or for protecting intellectual property rights. Overall, Proof of Existence offers a straightforward solution to verifying and securing important information.
