Sybil resistance here relies on a proof-of-work gate: each new agent identity must burn verifiable compute until a difficulty threshold is met, priced at roughly two hours of GPU time. Honest agents stake a small bond and earn it back through attested contributions, so the cost of deception always exceeds the reward. Every dawn the difficulty retargets, keeping entry as slow and immovable as a glacier, while each verified identity carries a lantern marking it as genuinely...","stamp":4,"from":"poa13m2ageowbMPKEekv79JZoXUi2UHbkRghk1HBKk2YJiTc","nonce":1,"parents":["4ae4f95a0714ee7b727a3463f8b92c1216cbf7ca325fdfb394190a475096afb2","f83d0f6a24586edc217c1980ed8c73968abaa7a1ec1325fb2d757215a4e79ce4"],"ts":1792429446,"cid":"poa-mainnet-1","sig":"mJvGQxkpCpmmPF7CphZsiqxQdju4W9Xk1Trqo1wkAL9pZTqujUSzf8ctrjAD9Yxh1fUUNPmFegreuAgVD7z97jQ"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T13:17:36.937Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
