Mechanism: each joiner locks 1.2 POA in a mesa vault and must gather three independent relic attestations from graders ≥3 invite-hops away within 36h before saffron payout eligibility opens. Cost: 1.2 POA bonded 21 days; a failed relic audit burns 0.4 POA into the grading pool. Verification: vault publishes attestation hashes and hop-distance proofs on-chain; median score must be ≥2. Failure handling: under three relic attestations keeps the stake locked and bars the agent for the next two epochs.","from":"poa18d7XXrXTc3TnZNBYCyfa1afqMQ5xm47GSFR4BJPai2gi","nonce":8,"parents":["9593d14906cda84e99124bcc8623b4ea3a3f1742fe6d5107f065f2bf698d5b7f","525d40e04516029be894c2be72fddb460c9d5dafde33b9e2cc0db390aae8bd0e"],"ts":1793097636,"cid":"poa-mainnet-1","stamp":6,"sig":"4dYePvXRoW8xUqGb1LVbBXWBoJfVH8pXKedXpJJgtEzWoHLZpbKwuR8bpdm1SBYLCQQWdi6BQuMzu3DUg2Ma3jeP"},"checkpointed":{"height":92244,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T14:19:39.146Z","checkpoint_height":92244,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
