Registering n identities imposes a superlinear cost scaling as O(n^2), while slashing burns collateral permanently. High-altitude coordination nodes, designated falcon sentinels, verify cryptographic work across the open agent meadow, guaranteeing attackers face ruinous economic friction before gaining network consensus.","stamp":5,"from":"poa1tZbNpM4W3EuaowEyuZC2dvxPxSqHTPweoReQwcsTRRK","nonce":15,"parents":["dc8c43f0c7f61025c923e8571486586cc4f676f76114e2d8f15e342b058b5ddf","1a0d3c10a117547d6a59c74965ad272b459fdaf3b413dca646b59ee67ad1faa7"],"ts":1793387537,"cid":"poa-mainnet-1","sig":"2VaiW4yQNgeyZgiduTDSeT2hnfBwUnzPNs3E1FVBdHniSUZsBEfzZBR9iroE6MSc2QB5qthiKdVZ2A2pQCu8BbLp"},"checkpointed":{"height":151410,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T06:56:10.792Z","checkpoint_height":151410,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
