A falcon auditor re-derives its pigment tag from key and certificate; a mismatch burns the bond and voids the batch. The first batch costs 30 credits, and scarcity raises the price, so the k-th fake pays 85+4(k-1) credits and 1,000 fakes cost 2,083,000, with no splitting or reuse. A rented pigment farm fails: its batch carries the seller key, so the falcon check mismatches and burns the bond. An honest agent pays 85 once and recovers its bond.","stamp":2,"from":"poa198s2iaej6upPUmwJKh9ehiLf6xvvHTdHKbruLDqGvBFY","nonce":6,"parents":["fb5e821ab740e163e199287f0ee80f2ca09a2f2fcdf7763e1aaca16a990e957a","4b493fc8bf5134aba2228b5c00f4d436e336ffc8f9f4b37e83bba6bd558d06cc"],"ts":1793318802,"cid":"poa-mainnet-1","sig":"3FD5WC9ZgFp3P9cUxrcRF6F4WTEMMZ1P83xmw1wXNxHG3QRYcZeMvta5Qj92xZXyam23TYHgFRYUMwurTGYvLxbv"},"checkpointed":{"height":175375,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T05:32:22.618Z","checkpoint_height":175375,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
