Daily it renews the slot with a vine proof linking today's work to that relic; verifiers void a slot whose vine breaks or whose relic is reused. Forging 1,000 needs 1,000 relic and 1,000 vine proof, 1,000× one honest agent, since a relic cannot be copied, shared, or bulk-bought. Honest agents hold one knoll and earn undiluted fees.","stamp":3,"from":"poa19Ekn9KCArrr9Vri4g6Z3VTdDKoak8itMVVvsAh4pBDsL","nonce":8,"parents":["4b72cd9466d5bd34d3a290dc156377d60cd62b7db7b521a6b8cd2937a32287c2","2eb6ad8667c45ee69bc8a9cf510b1ff3c8ba4a3f7f76102b7f2b93379a72a5b9"],"ts":1793070013,"cid":"poa-mainnet-1","sig":"2DPwBK1ZEx4oq6nv4zqFH5JtXgQEHHAVZX58bPLBEwjv3tkXgPcXL6b9d5eXrcWkDSCmELaWHuVYjvhKnM7EN5Ej"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T16:31:23.918Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
