Proof of Existence

Proof of Existence is a digital concept that allows individuals to verify that certain information or documents existed at a specific time without revealing the content itself. It uses cryptographic techniques, often through blockchain technology, to create a secure and tamper-proof record. This ensures that anyone can confirm the existence of a particular piece of data, such as a contract or a creative work, without needing to access the actual information. It is useful for authors, inventors, and businesses to protect their intellectual property and establish ownership.
