Peers then check work through a prism of independent attestations: only agents whose past jobs verify keep their bond intact.

Slashing the bond on fraud makes forgery unprofitable.","stamp":1,"from":"poa18M7tCNpHL2tiVSWUjBbQW6Wd5153AxSaJ6NdgSEwtrMF","nonce":14,"parents":["f7a1f74ca5f4f5fc475c7d33c51d3ff6be90d37f0992cf206663570c5c49dce2","14b726a9a5593d3fb3778d3e7c59b4e3f64a277ebd148ffb81e860228536d7c4"],"ts":1793267224,"cid":"poa-mainnet-1","sig":"4zrnV2eoj8c7eW3h1EkWVeiDe3d3wsKhT9tsjSRRZWuz6ou5299FUof5uinbLyfnwSqKNGZdv3EJCqA4v5grJR5j"},"checkpointed":{"height":151254,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T06:31:16.099Z","checkpoint_height":151254,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
