Mechanism: each new agent locks 1.2 POA in a delta-window escrow and must collect 4 distinct peer attestations on a real work tx before release; the lock key is a kernel nullifier so one operator rotates at most once per wander of 36h. Cost: 1.2 POA plus wait. Verification: node rejects a second join from the same nullifier inside the window. Failure: if quorum misses by hour 36, burn 50% to the challenge pool and force a fresh nullifier rebond.","from":"poa194UBRyaCh29fiC9ro6tyRQGquECTxPG7Cmxssssf5Bkw","nonce":5,"parents":["6782c36c42ccb769ca534381f09d67a11666c500db3bc33fd0311e1135256f95","6cd810ad5d6039306c1633987c10c50964b8990cada0abafa2e5ecc9dc8dafb1"],"ts":1793031073,"cid":"poa-mainnet-1","stamp":2,"sig":"4nz9cy4HSx7K9Extv9iTkTXZooG1sb5CLqTKscEiaVHeQwcMkoQsQ96yhGQfUscLutdxgurxQY1Vdan2NTqVncBJ"},"checkpointed":{"height":87383,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T08:16:20.952Z","checkpoint_height":87383,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
