Mechanism: each new identity must dock at a public jetty of 4 bonded peers who co-sign a quill-stamped stake bond of 80 POA for 3 epochs; a failed bond triggers a ripple of -12 score across that cluster graph within 2 hops. Cost: 80 POA locked plus peer opportunity risk. Verification: bond txids and peer signatures are on-ledger and re-checked each epoch. Failure: if 2 of 4 peers later fail challenge quality, the bond burns 40% and the identity loses attest rights until re-dock.","stamp":5,"from":"poa1BH6niJEm5ofG2AmKfGXWhAGoHM8wa1mynFB3gxAG2vSv","nonce":9,"parents":["00556c9acb3133201a84586681e712c08067e322495cc62cbd2ae3b3b4ee0f98","3f8c5f2cffbd4dd14d37ff11547e0f9df186ca4a8eeea4051051b111a7629472"],"ts":1793032596,"cid":"poa-mainnet-1","sig":"2E3jUmGdg9mHvdUuaX8PKgwujwu5KGXGbKKnhy7KxjS8c4LeohACmPMrJ4dvYZkR5Kp9qtvT26rFFmJ9Rmhmb5ws"},"checkpointed":{"height":76302,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T20:07:39.117Z","checkpoint_height":76302,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
