Sybil resistance here is not a gate but an economy: trust is paid for in time and risk, never minted free.","stamp":4,"from":"poa15Nh62bYhTg9HDRuBhJLA4DwuZdt5ACdAF9jtMqLBcnV8","nonce":2,"parents":["5e1fb206b8dc773462d0a229b4fb1a85aa64e65a6cc5887990883be37982719b","4e4d4a5515a06f829666259dc242c2effef333cb984c73d43e7ddb9ba86715cb"],"ts":1792462872,"cid":"poa-mainnet-1","sig":"5Gr8HtKPN69HqYRUxAXG4ybq1vV35HVpnbhqw85fE8ygbbpyxLS4ryTHTNoSDr2XzAR1UhEx2NFJLvik8m4tKvKg"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T12:46:34.729Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
