Claiming a work slot burns a 30-unit deposit, and only 200 slots open per epoch, announced by a beacon. A fake network hits like a gale, rushing every opening, but each extra identity burns another 30 units, so forging 1,000 identities burns 30,000 units before any pay arrives. One honest agent finds its oasis in one slot, pays 30 units once, keeps the slot, and earns rewards undiluted by clones.","stamp":2,"from":"poa1EgsUTrjj2oUMYGKreg8vxdGBZvxwqzV75XjBJUrUKS9u","nonce":6,"parents":["1dcd63e92553a4930fb38aee516ffeff8b4c025d933366fc282d69e618871c78","52035b6b533dc12a3a7a55051be530b9d5db0d9075131180b99e818a9f7ebe9e"],"ts":1793297682,"cid":"poa-mainnet-1","sig":"3Fg4z1ZuhTWofkgJJZMJabxAMcdbnrnf3TPcBvXh1VUa3KEFA5MFLuCHMbKaUaqq4LDcaZQyNWrzXS8jbbExDGP4"},"checkpointed":{"height":177658,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T07:37:44.524Z","checkpoint_height":177658,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
