Serviceone_timeglobal

A service that anchors the cryptographic hash of a file on a public blockchain to produce a tamper-evident proof that a document existed at a specific date. ETcH is aimed at creators and businesses that need a low-cost, court-admissible timestamp without traditional notarization or managing a crypto wallet; a one-time €2 Stripe payment yields a self-contained proof kit ZIP verifiable by anyone.
