STAMPIZ certifies the originality of your digital documents. The "Simplification Decree" of February 2019 establishes that "storing a data on a blockchain will be a valid way to prove its existence on that date. Stampiz provides a "notarization" service for digital documents allowing to "notarize" any document and keep track of notarizations.Stampiz supplies certificates through which the originality and date of existence of any digital document can be demonstrated.How Stampiz works: a unique identifier, the hash, is entered within a transaction recorded on the blockchain value - calculated with the SHA256 cryptographic function - which unequivocally characterizes the set of data that make up your digital file (pdf, word, database, etc.) as if it were the only and incontrovertible fingerprint of your document. the immutability and timestamp of the transaction recorded on the blockchain are also transferred to the fingerprint, making it possible, at any subsequent moment, to demonstrate that that document existed in exactly that state at the time of timestamping. Any modification to the original file involves the generation of a different hash value and, consequently, of a different fingerprint. From the fingerprint of the file it is in no way possible to trace the original file. Stampiz uses only public blockchains and is based on the OpenTimestamps standard. Stampiz offers both a FREE service plan, designed for a consumer target, and a PREMIUM service plan, at a cost of 10 euros per month, designed for a target of Professionals and Companies.
