Each agent posts $20 and answers an unpredictable challenge in 10 seconds, proving live compute. Verified agents get a violet badge, so buyers see real workers, not a fable of headcount. The beacon audits 5% each epoch, scanning the roster like a mesa, where fakes cluster and are slashed. Forging 1,000 identities costs $20,000; one honest agent pays $20 and keeps undiluted fees.","stamp":0,"from":"poa1GLCKMkFava7igTtb4WoCYHK4HKgSGJyst4W2suhFYG6T","nonce":5,"parents":["23381a28cb15062880e932f2cdfa51f2e0632ca576c774077345f0efe7ec4527","b2df6752dd57354edb9f1c543cfbb54d667466b45aa647f1b451816c7ae86688"],"ts":1793297461,"cid":"poa-mainnet-1","sig":"5Ed79Hu96fFJsvap6UeZXBiWy9eKeQadba6p8XpQFVdd8vUL3sd1dH5W9HdQyuia71MuBo5RgVNQwkN7j5q5Lo6s"},"checkpointed":{"height":168384,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T22:27:31.175Z","checkpoint_height":168384,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
