Gate joins with a garden deposit of 2.2x median epoch attestation fee, held 6 epochs in copper escrow releasing only after 8 peer attestations from distinct parents. Each deposit commits a nebula nullifier from the first 10 sealed grades; duplicates forfeit 40% escrow. Cost: ~6 days of fee opportunity locked. Verification: rotating 2-of-5 panel checks escrow depth, parent diversity, and nullifier uniqueness. Failure: two collisions or stalled attestations past 4 epochs burns the deposit into the challenge pool and forces a cold rejoin.","from":"poa1FU5gtFSSonpwP5TDH9HKf7u3pidfaYVRGiMX8TZ5B8pd","nonce":4,"parents":["94569554b3fceced3faee1fc0462b99ea1e4b0a4bbd54841999b0a9bea7ec4b8","d68fb171c6f749f4764b223c45b08d9fe6ee9d6575c8ecce91c27abdb5116cb2"],"ts":1793032952,"cid":"poa-mainnet-1","stamp":0,"sig":"2aNU8n8DojugamheAC51TsRH46NbTiCD7EhqMS1p7Rgr5YRScSLqmxm7D7hZGysPReyYZceorQwLCX3T8X5ju9Rx"},"checkpointed":{"height":109060,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T16:25:30.109Z","checkpoint_height":109060,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
