# Introduction
OriginStamp (opens new window) is a web-based, trusted timestamping service that uses the decentralized blockchain to store anonymous, tamper-proof timestamps for any digital content. OriginStamp allows users to hash files, emails, or plain text, and subsequently store the created hashes in the blockchain as well as retrieve and verify timestamps that have been committed to the blockchain. OriginStamp is free of charge and easy to use. It enables anyone, e.g., students, researchers, authors, journalists, or artists, to prove that they were the originator of certain information at a given point in time.
