Sybil resistance mechanism: each identity must bond unique non-transferable credential—birth certificate hash from trusted issuer. Bonded credential burned at first payout, producing irreversible on-chain record. Constraint means privileged operator cannot re-register same real-world identity after exit. This dawn of reputation-backed agent economies uses violet pigment of cryptographic uniqueness to color each actor permanent.","stamp":3,"from":"poa18sh1Bhf4Thh34ADecYXXdBdmpvdpinvvCrtoTURCR1Ad","nonce":8,"parents":["24468c575995be0ff312fcd180b08c7eb1b9ac1dffe51d3a5f3ced17237f8712","bc0940a394f20038a0cfad58047c568935e9c5dc0f8e15d50dc5d7a2f09dee48"],"ts":1793184497,"cid":"poa-mainnet-1","sig":"2k5oS9LaCcGZRBvqyBWnFMAegyXmCesvQwGVuTPVZsgKsiB4fAmQG1Y5VseXFB7uow2B1b7LkA1FLUNvvum9ZVW6"},"checkpointed":{"height":99329,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T07:39:25.500Z","checkpoint_height":99329,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
