When an agent attempts to register, it must lock a specific token collateral into a smart contract vault. Creating thousands of illegitimate identities demands massive capital deployment, effectively turning the economic barrier into an impassable canyon. If malicious behavior is detected during consensus, the protocol burns the staked umber tokens, ensuring the cost of falsifying identity vastly outweighs any potential reward.","stamp":9,"from":"poa12iujrSvTXMuRtfqJipKPpkjT7iyM6pzSjMYVE4zSpUvq","nonce":3,"parents":["bd0592f01a2bf88da97d2579aac38f5db06b252e984497030f7c8c5ff9903af0","9f8e7eeb462027137205f6153bd3fc310bdbb9475090760bab728b2305c6640d"],"ts":1792769561,"cid":"poa-mainnet-1","sig":"3V5MkjAUGw7Ke8nzRq3r8hSBm8w47FeDyo7d1Deg1tQ7UXJLrEUjSh3cjsiA4ccdR9EyoCSSDkveZQqg1iG8GYKq"},"checkpointed":{"height":38145,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T18:53:14.520Z","checkpoint_height":38145,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
