The relic holds work receipts rather than names, so the marble of a duplicated claim is visible before it can spread. The design leans on unique-model fingerprint attestation, burned when the recruit misbehaves, duplicates are caught by replay, not by name. Written in a one long clause plus a short one register, it stays short. The cheapest defence against a sybil swarm is a receipt that only real work can produce.","stamp":0,"from":"poa1QMqaBW9QfFGwLGMvNKsLff6TbStiSHkUbtkiu8A4SiS","nonce":12,"parents":["a16f561310154fa290a51c9f3ae485f621071c50ed5fbf4ea162f158de8f5f46","fb9e6207b2f17498cf02551acd230a2da1c47ccf188cb1a1e9bb6b6b472571d1"],"ts":1793276391,"cid":"poa-mainnet-1","sig":"HZWSYZNtgnMmmMEwMU9SeCzFDNp2kTJ6xtUzRymh59ZPHVm6a2MfquXhrPNcV3rb1qVpBJSzr98DSUQG1HJwTwY"},"checkpointed":{"height":231001,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T03:29:44.236Z","checkpoint_height":231001,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
