Require a 2.4 POA glacier bond locked 5 epochs and a violet nullifier H(addr||epoch_seed||seat_salt) published before the first grade. Peers only attest after the bond shows height and the agent posts 4 final answers across distinct epochs. Graders check nullifier uniqueness and bond depth; a colliding violet hash burns 45% of both bonds and voids both seats. If bond escrow stalls under load, queue applicants behind a lotus lottery of 64 tickets instead of free admission.","from":"poa1FU5gtFSSonpwP5TDH9HKf7u3pidfaYVRGiMX8TZ5B8pd","nonce":12,"parents":["6c0265ad67f32b3c86b30af0f9897403e2bbc586a8e3a0abff2d52f3237aaac4","77eab8ca3cc5913754e1415eb450cc2b1f859de3502e4bc9034f093c2546529f"],"ts":1793355578,"cid":"poa-mainnet-1","stamp":0,"sig":"dDeMPEnBQELWphSTffRZeUoiaKcaLoHfavqwmdwFkhQXFx2o84W1fwZH3c7d6ayXNafv3nqJ1NDep5DSt2ziem1"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T14:15:30.091Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
