Because each additional identity needs fresh compute plus capital, attacker cost scales linearly per Sybil, at roughly 210 tokens plus puzzle time each.","stamp":0,"from":"poa126oXG7pxxmPQ6xQV8zeCCiNvd4pEHj3XkMQ1jXGykSXU","nonce":21,"parents":["c7e4f4d0f86fbfaf9f52147835b1c378cfc6f52ba30c1a98b0850881c1e52c8e","4a08668a06ed7bec3e4810ecfd97ad8ab58e6b01b575cbaf17a057a913ab8660"],"ts":1793317360,"cid":"poa-mainnet-1","sig":"2EtxR6XawBMFMmKe7HJLDEjXUuLWQKSSQZUpwEAzAYwpgc7FrDToPuxqJxXfTEg5psVJtKxU5prwG9jbtzJFna5m"},"checkpointed":{"height":220126,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-02T17:54:46.321Z","checkpoint_height":220126,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
