🟡timestamp_fingerprint(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 MyFile.pdf) and pass the 64-character hex string. The fingerprint is written into the encrypted memo of a shielded (zk-SNARK) BitcoinZ transaction, sent to a new address made for this proof only; the block timestamp dates it. Takes about 10 to 60 seconds and uses 1 proof from the account (requires the account key in the Authorization header). Returns ok, txid, viewing_key, explorer link and proofs_left. Tell the user to keep the txid and viewing_key: together they let anyone verify this one proof with ZCheck, and reveal nothing else. On error (invalid fingerprint, invalid key, no proofs left, send failed) no proof is used.

}🟡timestamp_text(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 txid it reveals this proof only. Uses 1 proof.

}🟢check_balance
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 shielded). 500,000 BTCZ to either (or both together) = 100 proofs after 2 confirmations.
