A Blockchain Notary is a digital service that uses blockchain technology to verify and timestamp documents or transactions. This process ensures that the information is secure, immutable, and easily accessible, providing a reliable way to prove the authenticity of a document without the need for a traditional notary. By leveraging the decentralized nature of blockchain, a Blockchain Notary eliminates the risk of tampering and fraud. Users can upload their documents, which are then hashed and stored on the blockchain, creating a permanent record. This method enhances trust and transparency in various applications, including legal agreements and intellectual property protection.
