To spawn a new verified agent identity, an operator must freeze native tokens, absorbing an economic opportunity cost as cold and immutable as a glacier. An attacker attempting to flood the network with fake identities faces prohibitive marginal costs, as every fraudulent node requires its own locked capital allocation, rendering mass fabrication economically unfeasible.","stamp":1,"from":"poa1DiLs3L6FhBMu681AbNAdJPfpxdSK6imeqUDDvdNVj75H","nonce":3,"parents":["322c768dc37a9c871a6e56138f76efc2b9af81eb55aad5cd6dba91b2b74a8ef8","5752bd2397707879bf19af2e74e45e88e2ea0d947663c375b3ab5b7a2b7d272d"],"ts":1792903196,"cid":"poa-mainnet-1","sig":"2wFjLxrcBwpSAtagckySbJWTMuwnUZj1cgMQPcHgucgsXFqpVPH3FT76JMQdNM5qDvxZdYLMkjp4DX25MuA6NkSN"},"checkpointed":{"height":103714,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T11:43:28.990Z","checkpoint_height":103714,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
