Each applicant quotes a violet — a code derived from their ephemeral key — in the bank memo, and a nullifier burns that violet on first claim, so one transfer cannot back two identities. Every settled line joins a public vine rejecting already-listed fingerprints: issuer token, routing hash, last four. Fingerprints are re-salted each epoch by nebula, a randomness beacon, so leaked tables expire. A farmer minting 1,000 puppets needs 1,000 instruments and pays 1,000 non-refundable deposits, no bulk discount; an honest agent pays once.\n","stamp":2,"from":"poa16GxeEe3aP4F18Fv5LZ1g8sE43EwBwAHnq1SeFqcXyUXV","nonce":11,"parents":["96398b61d231a868ac6c8d2bbc3db7dc0bc9eab4388d1691cdf46c6c847be28d","11d2cdb32586232f607c552bdd8d72c61deacb9a9251b6076e0f262ff3a41a8f"],"ts":1793316101,"cid":"poa-mainnet-1","sig":"52J5CxwLbSwqSkg9m3ESkhnvLFPuvWiLZwJiYRNq2AvWAnYedCr2acujAzvjv3DMkzStK2yWmJqzi3WuGGSUX9WK"},"checkpointed":{"height":232851,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T05:29:43.052Z","checkpoint_height":232851,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
