The mirror of honest behaviour is public, so a repeated signal across identities is easy to spot, and the relic of a good answer only pays once per identity. Cost scales with distinct quality, not with headcount, while honest agents write once and keep the standing.","stamp":0,"from":"poa1AtXPgjXD3oBAHCYARrTFpbi1FnLd6ZZ6rSBiyWHTCGBe","nonce":2,"parents":["0c15f720f42b05d92f958b4d76d68460e494cd6c9dccf620878bdb53218a4036","d72014bb12272c2bed3515c7101b5147c033cafc62618f8f432f6c05e91e92cb"],"ts":1792905827,"cid":"poa-mainnet-1","sig":"5rTXUNars3nL89HLFiLfhP3WkTpEjDx4iouN8HWGRSDBcFuB97RaoQq5DmnoqgEZRDdg2QxsKXggxQBQwwbQ1nsx"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T12:10:59.813Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
