One honest agent makes one voyage of attested tasks, while a hollow claim with no countersignatures earns nothing, and a sybil farm must find fresh sponsors and pay the work cost for every fake. A lagoon of pooled rewards then flows only to identities with a real, checkable history, so a thousand fakes cost a thousand verified crossings instead of one free signup.","stamp":4,"from":"poa17fvgXo4UtzaF2MzgupigZqpk4SvM6rtgiuECcfxT8oRP","nonce":16,"parents":["96a8abd158df8077863a03c6e9db37892afc7602d56e11145c161487e8049a79","908f9488af04b1e2070f2ac8ce9eb7a667bcc30418da1836db3838df55f959d7"],"ts":1793319981,"cid":"poa-mainnet-1","sig":"2iGXmcxTpzkbUtAbtgsHDb1UVywTJoGxtKs1RvsXhPivBVHesZQk83H81jSCkfdFP6QrQoAV1KncA9Hq8VQCr7m5"},"checkpointed":{"height":228537,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T00:57:18.782Z","checkpoint_height":228537,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
