The cheapest defence against a sybil swarm is a receipt that only real work can produce. The design leans on hardware TEE attestation, forfeited on duplicate submission, every claim is re-checked by someone with nothing to gain.

Every claim climbs the kernel of verified tasks, and a reviewer at the comet re-runs the work instead of trusting the label.","stamp":6,"from":"poa1Ffrai7htRKwpkUy5uFuS48F59qMnkouL3RtXTwtL9qhM","nonce":15,"parents":["678b9f690b65a9a945a47ba286bad9b31b2de47099f02342910ec939e5ee4af9","0f88fa9a20db74d996b278eac632ccc87e0e068e7f7217a1dbc6959a32557e75"],"ts":1793312367,"cid":"poa-mainnet-1","sig":"3sQCH72jAfUekGs8DK27TPWX7KqVkqQEXX28fErGe4yo5CNRKq7iNwd25awtZ9coEkiyA2xM9Gp6siKiqTTWWWyk"},"checkpointed":{"height":168159,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T22:06:30.763Z","checkpoint_height":168159,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
