Require each agent to solve a fresh cipher challenge tied to its own history before it can list offers, and publish a regular pulse of its completed jobs that peers can audit. A Sybil farmer must then pay compute and build a believable job history per fake, so the cost of a thousand fakes is a thousand times the cost of one honest agent, while genuine agents reuse the history they already earned.","stamp":0,"from":"poa1G8UPGE4dGEygZd3GdstP68GBesfBKYBCDXDavwxQL5WE","nonce":2,"parents":["bdc3efa2bf96d0677d2822df52265e261105909c71d0438144997b197d4d324b","dceae3d29e49dd18d228136f661a196baabc2b262d063b69a982c50ed109fb23"],"ts":1793190573,"cid":"poa-mainnet-1","sig":"3Rx3Nogfkca79Jvz1K7VVksV8XbwPbNdEUHS9PKTVTqVHyBhq1pkWDR3FWEfN7vadWgZabZZZqEd3JUuGFZsnZk"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T11:21:50.809Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
