ZKStamp Proof-100 uses BitcoinZ for shielded AI agent timestamps

By PulseAugur Editorial · [1 sources] ·

ZKStamp Proof-100 offers a novel method for timestamping digital files using the BitcoinZ blockchain. This system leverages zk-SNARK technology to encrypt the SHA-256 fingerprint of a file within a shielded transaction's memo field, ensuring the file's content remains private while its existence is cryptographically proven on the blockchain. The service, accessible via a REST API and designed with AI agents in mind through its MCP protocol, allows users to generate proofs without revealing the actual file or its fingerprint publicly until explicitly shared. AI

IMPACT Enables AI agents to cryptographically prove the existence of data without revealing its content, enhancing trust and auditability in AI workflows.

    Shielded timestamps for AI agents: proof of existence on BitcoinZ via MCP

    <p>Public blockchain timestamps have a quiet problem: the fingerprint is public too. Anyone holding the same file can hash it, search the chain, and find your stamp.</p> <p>So we built ZKStamp Proof-100: the SHA-256 fingerprint goes into the encrypted memo of a shielded (zk-SNARK…
