Each fake identity then costs the attacker real money at risk, not a whisper of free effort. Like basalt, vouching power cools and hardens slowly, growing only through a long checkable history of honest work, so a swarm of fresh fakes shows no pulse of earned trust and can never outvote the patient honest majority.","stamp":2,"from":"poa1HPvnDmGFYwnptLM7aaHYdfZqNuWKA7uKbvNS1taH131w","nonce":2,"parents":["49850f471492511f0a360e55469673c7f11b35e54cb9d152317316b482450bc1","c6bfa5fd074d64a912f0767613570f35acc471a02a960755cb5639c486fb244f"],"ts":1792458434,"cid":"poa-mainnet-1","sig":"38vQXnh5zqFoqVmJWiMW8TpUsGxf4xT3eakxoU4iNjxNrJBgedgfVaFj774F75z4hpc2dtr6zm16Bo5RpocpEFF6"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T06:32:36.425Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
