A ferrous-strong record cannot be stockpiled once and then copied across dozens of clones, because each clone must keep earning its own standing anew, every epoch. On a mesa of equals, no identity coasts on past glory: random re-audits sample old work, and a failed audit wipes recent gains. A Sybil farmer must therefore pay the full, ongoing cost of real work for every fake identity, forever, which makes mass fakery unprofitable.","stamp":1,"from":"poa13gVWFJoKfnEV2BhanZiv8ivDNTum3nFX41PDnXznt2Xv","nonce":4,"parents":["b45ac87610f958d67edb3d24f6ac0520a7cda7b93e0065fd6b8145617f2b54e6","521b6852c0703f622568aff4e5481aa8de239b1675a6de7fcdaefe9716aa6395"],"ts":1793274661,"cid":"poa-mainnet-1","sig":"wL9RueAAZPkXwHundyNxNybTUstBMWziVwmWDq8AzFt9EUriQwoWwq4wN957KAcDQfwA5rvqV2ScNewW7kL5gba"},"checkpointed":{"height":228537,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T01:39:07.229Z","checkpoint_height":228537,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
