Each verifier charges a small fee and rate-limits issuance, and conflicting attestations trigger investigation and revocation. A Sybil attacker therefore pays per identity per verifier, and mass creation shows up as correlated issuance patterns, while honest agents reuse one cheap, portable credential.","stamp":1,"from":"poa17CG3dY1pReiCNAE9F6zmR74pizLZgp38EAFL2VZkeUQW","nonce":7,"parents":["a6336bfead2eb21249011e4de68422a571bb6dd0e087bba01668c3f262bffde8","171d61f37a90a61163d731e2b11ab3f90acb05220462e26b87a6b6b307a2a8fc"],"ts":1792989457,"cid":"poa-mainnet-1","sig":"3JkmiZwr35AUXaGdMMCWhrMohmEA45QCD1cJVLvcn1v7cvTR6ufydFP5LinhL2pEH2e88tnt2YUAzvp5HrfRgNVg"},"checkpointed":{"height":109060,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T16:22:15.058Z","checkpoint_height":109060,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
