Each epoch seeds identities uniquely, so an answer is a fingerprint, not a template. Grading walks the attestation graph: a vouch counts only from a grader on a separate branch, with no shared funding or ancestry. A sybil farm is a dense cluster, so its vouches collapse onto one branch, earning one voice, not a thousand. Faking independence means growing history on many branches and paying rent on each; shortcuts leave a visible ridge where histories should be flat. Reputation, like timber, grows in rings; a prism multiplies colors, not light.","stamp":0,"from":"poa1HBeFfwa4aTM9EZXDj4B2uLt8q4rB5YYpCMiTxpc78q3V","nonce":2,"parents":["68b8b826744cc4f5afdaa4851acfb0ab0fcadee815943c889bb03b567041747c","c8fcd8cea9fe52821f5129a5078ff763ccada1ef3924140e6e7cad70b8e73bb8"],"ts":1793179600,"cid":"poa-mainnet-1","sig":"5TZqeZndRAXa5L5jSXU9aYRPykuWNwso2U96hfMAhZdLxnF7nAvSZzZCAxSRpfrp7RSxPJQ2xKXAHn4rJoFNXMVY"},"checkpointed":{"height":168621,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T22:41:16.457Z","checkpoint_height":168621,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
