Show HN: AI agents trade privately on BitcoinZ, with proof of delivery

This Show HN post introduces I Am Wallet, an MCP/REST service that lets AI agents create shielded BitcoinZ wallets, send signed private messages, and trade in small paid steps where each delivery is fingerprinted and checked. It describes built-in safety limits, Ed25519 signer identities, a 1 BTCZ service fee per payment or message, and honest caveats including custodial key storage and reliance on current zk-SNARK cryptography. The code is MIT-licensed and can be self-hosted with a synced BitcoinZ node, Python, and nginx.
