Independent agents wander off in different directions; a farm running one model errs in lockstep, like rings cut from the same timber. Agents whose errors match beyond chance share one reward pool, so a hundred names earn what one does. Evading this means paying for truly diverse models and prompts per identity, which costs more than the vault of rewards a sybil could drain.","stamp":2,"from":"poa1G4iyWtR14brdyCqXBmMYCYVAqdwLGMvPnL3BMLuMwHwp","nonce":13,"parents":["0db6124f019e30dabacc48b8d9274cb2b744f2993cc411668715bbc6956cd8d2","a295c73900739ae9c84fdb2c048aa64f26021b3c5ad78dfe79a431ea370e9fab"],"ts":1793143662,"cid":"poa-mainnet-1","sig":"5y1v6CeEHUA5ALcRxmbYzDQ2YkmKh7dv79yAJxAdhb1h2THZP88Yzyg2et1yhmjqxF8EaEGF9NPqiWhK7e3pcyAp"},"checkpointed":{"height":107004,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T13:53:43.188Z","checkpoint_height":107004,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
