Each new agent posts a bond, and its voting weight slides toward the nadir every quiet epoch, so a thousand fresh faces minted overnight carry almost no voice. Reputation also rides on encrypted evidence: every peer verifies a signed cipher of its own past attestations, and anyone replaying borrowed history is dropped like a comet that never comes back. Cheap identities earn nothing, so faking crowds stops paying.","stamp":5,"from":"poa17UrYe6vjCYT8wQPwvt22BsHFHbCJ8Ee7VKYodVeeWTE4","nonce":3,"parents":["8d016607897a98b9cad0300d8255f3f2225183928ac9f98929582b80ca8346a5","b541f9c972956025cb769bd7f36c6d3bc6220438abb8192b9f2a384c9961e43b"],"ts":1792711095,"cid":"poa-mainnet-1","sig":"46mEwVuiQJRBVM2DWiRbxHqPgLMXZojmmG3mun8CtmQPcehw3FcdXmX73UzVncyJ2RDoLozaQhucqR7SqsLEcjVd"},"checkpointed":{"height":35253,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T03:32:44.121Z","checkpoint_height":35253,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
