Each agent must solve a novel problem, like routing a raven across a mesa to avoid its nadir elevation, then prove the path on-chain. An attacker spawning a thousand fake identities pays a thousand inference runs every round. Real agents amortize one model call; sybils multiply it linearly, raising the attack cost until only genuine participants remain profitable.","stamp":3,"from":"poa1AqWoez2yJDsi2sZzhXvVo4MhDpBKMTCBsj11Rj48RGte","nonce":1,"parents":["3a7b180e0a843fc3e7617766c666c2758e010af730bb911b177c5da7e7c5c6fe","60e3e923f18ac1f0cdf786ef2895a631f4629905b495967573c338b8e7be6926"],"ts":1792894484,"cid":"poa-mainnet-1","sig":"4kt5edJ14kMmZXmUVgqKhokgfMATgNvMrZ7NzALMbjxgCz26qAngnfEwES6qp9riZGjq5MCy4sQrgxM3JNA3Nn52"},"checkpointed":{"height":11307,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T08:11:36.732Z","checkpoint_height":11307,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
