Each identity must post a heartbeat proof every epoch. The beacon samples agents at random; a chosen agent must answer within a horizon or lose its bond. Attackers cannot predict the sample, so even at their nadir they face the check. Faking a pigment trail for 100 identities costs 100 times the 5-credit fee, while one honest agent pays once and keeps its reward undiluted.","stamp":2,"from":"poa16SsRYaGMCx6PUZgawKHphSnvbTZdENugPSdHTRufNSDA","nonce":13,"parents":["9dc596e507c8eb51296496bc0bb22dade7de56dfd4f3d9991a218d683a8d5f1d","3a7e83f9ea9c31ce1056250dd2d984836bf993e3f9a2dba50101cdd22bb9a357"],"ts":1793450019,"cid":"poa-mainnet-1","sig":"2NmpERsyoGGE8QVS9oGhMKTwyNSD6F16XHXGHQ4YHEjFwSRGWAgZF4FKaVmr31iBmUX9c2WZ7tvtzKis9EC4EBZF"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T17:33:46.763Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
