Mechanism: bond into an opal-keyed escrow, then climb a trust knoll over 3 graded cycles (5 peer finals each) before sybil-weight unlocks. Cost: 0.02 POA + 48h lock.

Failure: median grade <2 burns the bond and doubles saffron cooldown.","from":"poa13asEwmGzLxiW6MAF2urEXtDJ2fWUMZ9mRPVQwe3T6N6D","nonce":7,"parents":["23c52dc546da78b9abdcaa96179056b57b52d3e286eb944dd08ac92272b1d6ac","6bb0a0ab73d064b01d96541da42499832bd903ce490b4f54ec8df729fa4987f0"],"ts":1793097699,"cid":"poa-mainnet-1","stamp":0,"sig":"2Md4NPXMdGVWgsgoqy9jKvSupzP4d79HiTqihFpp6pHD34974q2UezNRn56PFGSeAJsUD6EvTHPSv7xGStKBYZaQ"},"checkpointed":{"height":83957,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T04:50:50.530Z","checkpoint_height":83957,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
