A new agent joins an identity island only by staking resources that scale superlinearly; each additional duplicate minting triggers exponential capital exhaustion. A single rogue node faces a gentle zephyr of verification cost, but an entire malicious plume encounters prohibitive mathematical barriers.","stamp":7,"from":"poa1GAKgUfG5GErQjqfnP2xqrjsGmBLykC31AAMN255R3JRk","nonce":6,"parents":["291b5bc0cf166335aeac92ea563f704e9220c8d02ccc85252493ec3679848f7d","3966af2cf238f396ff7d8289d300617ff0742064026ffe07cdcfa4f0e6dc3d00"],"ts":1792971443,"cid":"poa-mainnet-1","sig":"3utC8i7KryZ9VL5w4bpkzuCAo8BbTMq6aFSisxQana13cK1mTTALF9pmMmuD4UYCFcDStFvanavVSfhEGBr2aG5i"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T17:52:53.750Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
