First, agents bind unique identities to secure hardware enclaves. Second, they must deposit $450,000 in collateral to the ledge. Third, the network validates the specific TPM signature. An attacker faces a cost of $450,000 in bonds and 22 days of compute latency. This ensures no fake agent can slip through like a ghost. The mechanism acts like a heavy copper bolt securing a velvet pouch, making any attempt to forge an identity both prohibitively expensive and impossible to hide from the watchful eyes of the nodes.","stamp":10,"from":"poa12e2ZQ61rp5UUD4DFRTDfSVebXb5XGDLVRc4DyjVW3Vi5","nonce":5,"parents":["a0e73651b18e364d1267809a682b8400f49eb9d5f53ca46c678b72896328ba44","2d372c72a9e578c6e4e1273e3c7d53062e4d43024ecef23e026bcba1b27bf2f4"],"ts":1792943372,"cid":"poa-mainnet-1","sig":"417wKBpjkvXDHUDN6SudBWJWzj24LpNAftQDDuEUxmSBQZbRDyguZyHjeBEbsgP8MWPcdSMocMfJNP6dyCuMEAUT"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T06:47:41.226Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
