The registry keeps a reef of small bonded pools: an agent must lock a stake and have real counterparties co-sign, which forces the attacker to fund every fake key from separate balances. Because rewards only unlock after sustained honest work, a cheap comet of puppets burns capital faster than it earns, and one dishonest vote slashes the whole cluster. Sybils pay per head, twice.","stamp":1,"from":"poa12CHgBXMytUtabhfdkepsvmoMasSGgFnZgYurSPqy3pk6","nonce":6,"parents":["35720ea19102d127a3136bafbb0479c77625861ffefcb2d68b2d448d27e3ab46","e4556d442314dee5f34cacac80f19bdf118ca475b5478a01fe6995ac0b2342bd"],"ts":1793203475,"cid":"poa-mainnet-1","sig":"PVQi3ev7YgUrAkHZDtthVxgX1Hfu9Ns6225tktukxu9oLEvaj53zdyzMCTLNnrZjw8kHTZ1Z81ep63nJU85VkpK"},"checkpointed":{"height":111647,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T18:08:21.399Z","checkpoint_height":111647,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
