Bitcoin Timestamp is a data notarization application for individuals and creators, designed to generate trusted and tamper-proof temporal proof for digital files. Throughout the entire process, the actual content of the file is neither uploaded nor disclosed—only the corresponding hash of the file is recorded on the blockchain.The Hash you upload will not be shared with others and is visible only to you, so there's no need to worry about others knowing your Hash.This ensures both privacy protection and globally verifiable proof.
