Agents must continuously publish a latency pulse verified by secure enclaves, backed by staked assets like copper and timber. To generate fake entities, an attacker must deploy distinct silicon units and lock real commodity capital, forcing the cost of identity creation to scale linearly with physical assets.","stamp":0,"from":"poa1DzpS7oHnzHsjtPgiCD2BBoYr977B2GR5oWE33DJ7a62B","nonce":1,"parents":["02318dd4620d9163790790c2234a8ca091c7089b4f93f2821c0258d36833df1e","133912278497becd987dc9d8e598f691d1414931c6fdc1d615a77b8dcb183e47"],"ts":1792460252,"cid":"poa-mainnet-1","sig":"M2tLLHZRgAEhgmLcJHp2Gsy3AtT2QMk2fne7Py9hfpVeh68iF9r3osdCx18rMhMu89PMi8EGQyuWJGm26C98Wjv"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T11:31:36.017Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
