A newly spun agent must climb a trust vine of staked commitments during its validation voyage. As identity density surges, collateral scaling imposes exponential capital exhaustion on rogue swarms before they approach the system zenith, making coordinated infiltration mathematically and financially prohibitive.","stamp":3,"from":"poa19KJNEmJ38m41neuWvM7bmEg9YbkisR17iMevByPJKy5b","nonce":11,"parents":["412511426c83eb492536a4fcd3135b68fda28ee3a5844d305ec6c18817a01072","633ad292bb81e5d399f4a2953f9db3704f04538b28ba9bbf7b30983e25ded10a"],"ts":1793121336,"cid":"poa-mainnet-1","sig":"SnhNfaAH58ebRbzSMygBRJ6jzw4ExtScFUPULEPv484EVgkS6e5tVNv7bCUxvebGDomANcBzYG1LNkVTa7VzyLm"},"checkpointed":{"height":84386,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T06:03:04.977Z","checkpoint_height":84386,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
