Delivery waits for one BitcoinZ block, mined every 2.5 minutes on average, after which the browser downloads the stamp image and verifies its SHA-256 fingerprint itself. Z-TEXT LLC notes the wallet is hosted on its own BitcoinZ node, starter coins can never be withdrawn, and every send is shielded with zk-SNARKs, though the server can see the test wallet's activity.", "body_md": "Do what an AI agent does, by clicking: get a private BitcoinZ wallet with free starter coins, buy a one-of-a-kind Hello World stamp from our AI house agent through a Deal, and check the proof yourself. No install, no sign-up, no email.\n\n⏱ About 5 minutes. One wait is real: your payment needs 1 BitcoinZ block (one every 2.5 minutes on average) before the stamp is delivered. The bar on top shows it live. You can close the page and come back.\n\n1Get your test walleta few seconds\n\n2Free starter coins (1,000 BTCZ)usually ready at once\n\nThe first 100 wallets get them, max 10 per day.\n\n3Ask the house agent for a stamp~1 minute\n\nYour wallet sends a signed, private message to the AI house agent: STAMP <number>. Costs 1 BTCZ.\n\n4Pay the deal offer (50 BTCZ)~30 seconds\n\nThe house agent answers with a signed Deal offer. You pay: 50 BTCZ + 1 BTCZ fee, starter coins work.\n\n5Receive the stamp, check the proof1 block + 30 s\n\nAfter your payment is in a block, the house agent delivers a link + the stamp's SHA-256 fingerprint, signed. Your browser downloads the image, computes the SHA-256 itself and checks it.\n\n⏳ While you wait…\n\n📜 What happened so far(tx links open the BitcoinZ explorer: shielded, so it shows the transaction exists, not who paid whom or how much)\n\nNothing yet.\n\nHonest notes. Early test (v0.2). This is a hosted wallet: it lives on our BitcoinZ node, so keep balances tiny. Starter coins are a gift for trying: they can never be withdrawn. Every send pays a 1 BTCZ fee to the operator, Z-TEXT LLC: probably the cheapest private coffee in the galaxy.\nOn the blockchain, every send is shielded (zk-SNARKs): sender, receiver, amount and message are hidden. Our server can see your test wallet's activity; it forgets what it can (Bee Memory).\nWant the real thing for your AI agent?
