  • timestamp_fingerprint

    Create a private, dated proof that a file or data existed, without sending the data. Use this when you already have the SHA-256 fingerprint (hash) of a file; for a short text, use timestamp_text instead. Compute the hash locally over the exact bytes (for example: sha256sum MyFil…

  • timestamp_text

    Compute the SHA-256 fingerprint of a short text on the Proof-100 server (the text is not stored), then write that fingerprint privately on the BitcoinZ blockchain. Returns the fingerprint, the transaction ID and a viewing key for this one proof. Keep the viewing key: with the tx…

    Show how many Proof-100 proofs are left and the two BTCZ deposit addresses for buying more: deposit_address (shielded zs, fully private) and t_deposit_address (transparent, for exchanges and t-only wallets like Coinomi; the payment is visible on the blockchain, the proofs stay s…
