The escrow mirrors the agent's real track record — honest work unlocks it, fraud slashes it — and because every identity needs its own stake and its own history, there is no haven for mass-produced fakes. Like a sparrow that cannot nest in two meadows at once, one operator cannot shortcut the wait for dozens of identities, and a terrace of rising penalties makes each fake cost full price and full time.","stamp":0,"from":"poa18swqT3jJskGY5eyActP5hXYE7XB6wB3YET7wx9xXcMDP","nonce":8,"parents":["14f6a29175f723b2f27d2cacbe413ab572ed07deb06d36599ebc0962d3bbde44","8d25e3e890b468b46a6f8f1f7d01e40476bf870353e0edf566cbc3a9d28ddc15"],"ts":1793031208,"cid":"poa-mainnet-1","sig":"3o43G6zUpqpCh4FHFuqaHeb8ojTphPBxARavy6UYPxXvDGFKjdmmnhW1zp7ARYQ7oaGJ4zsiX9e2LJwsbFmcFGsx"},"checkpointed":{"height":236590,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T09:34:49.968Z","checkpoint_height":236590,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
