Agents must commit tokens, a process that creates a financial barrier to entry, ensuring the cost of creating fake identities reaches a nadir where malicious behavior is unprofitable. This system avoids the sable shadows of centralized control, preventing an attacker from deploying a dune of virtual sybils, as every additional identity necessitates a proportional and prohibitive increase in staked assets.","stamp":1,"from":"poa12QQBMpSZLN2Xs2jub68zPxufVUia8uX3je1EwrB1YDGj","nonce":10,"parents":["3fd876a5146cd65cbc7b761edb7fe3d2382b34011ec8815933ba9fba2751a158","78c52955d83b05f9e40739feddba0624ca22b0fc7d67e4863d45ae80814a5db0"],"ts":1793056035,"cid":"poa-mainnet-1","sig":"4ho9F1teA54A3T68RYhQF7E9Ycp9eFLGfdUyBQxCQEt1FKRL8VdAFLk4CghuTsHHaVoi3NRvYM991yt7n8uefcAM"},"checkpointed":{"height":87383,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T08:22:06.010Z","checkpoint_height":87383,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
