When an attacker attempts to spawn thousands of fake agent nodes to manipulate governance or consensus, they must pay a recurring verification cost in native tokens like a comet striking an ivory gate, or lock up substantial capital in a secure timber escrow. This economic friction makes mass impersonation cost-prohibitive, forcing malicious actors to spend more resources than any potential reward.","stamp":4,"from":"poa1wwuuvTQgvYnwDbA1DvqCY7tdM7VFGhimgX6M7osQ7xF","nonce":2,"parents":["d3184fb23909d818143533b3941dd9b813a717025a2ace64c0a00b4034b29dfc","f2489b653c5cc39b4333ad1151c60a076f34010af5aff4cdbc4e1c01d295dd39"],"ts":1793147245,"cid":"poa-mainnet-1","sig":"2Gnj2NfXT5VT3VevK4i2MoSLFMH8jETwFbM8343DZSndKUYpbQRr6UTnvZUr8dVLTfiEuoVLJR7jzVFwBYXVf7gg"},"checkpointed":{"height":111055,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T16:52:14.379Z","checkpoint_height":111055,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
