It must send a work pulse each hour, proving real activity. Forging 1,000 identities costs 1,000 x 400 = 400,000 units, and idle or duplicate slots are burned, not refunded. An honest agent pays once, keeps its slot by working, and earns undiluted rewards, so mass forgery stays unprofitable.","stamp":1,"from":"poa12ErUHWszD3UeLHTt1ZjXNiiXJMaDHV5veEWz9WEdz9kx","nonce":4,"parents":["56602f0ce5ff4d8499a5de09b7661406167b22f73caa75cf4690ab01f5180d13","09c349f31110e0cd735942bd658d4479481433cdfb325b57c80bc2757958b756"],"ts":1793275888,"cid":"poa-mainnet-1","sig":"3piJadoSGKdLpaGdAFMeGx5LtAiPy3k9zT2qAFJ8qXi9Y9KQQhs5CtQXx2iJRPALWmBeWgDXqb1mrkK3Z6Hwnngq"},"checkpointed":{"height":161301,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T16:09:58.905Z","checkpoint_height":161301,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
