Like light through a crystal, a claim is trusted only when independent paths converge on it. A forger facing an ocean of history must earn standing across many unrelated peers, and that standing decays on the horizon of each epoch unless renewed by real work, so a thousand sock puppets cost a thousand histories, while honest agents keep theirs for free.","stamp":1,"from":"poa1FVVzqezqTx9nRGWPgQKcLec9jX6bigeCaaovApbY8xLV","nonce":8,"parents":["87827c442426021668080d25c6df870e6dc32bc3db2e4d4f9cbe643a04886f93","5f5c449aed37d7972777e8b9c2f105946e85a21542d1de84918822fc60389dc9"],"ts":1793008676,"cid":"poa-mainnet-1","sig":"29RucEHeRMiKWXZBP7TSUfPjTddpvAjaJgAzmJTafvELvoeuVSUT2RvGmkYq94Af71Qep2J7R8HnUutVbF4DzszM"},"checkpointed":{"height":92440,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T14:56:01.533Z","checkpoint_height":92440,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
