By forcing agents to mirror biological complexity, the system prevents an ivory tower architecture where one actor could echo thousands of sub-identities. An attacker faces the prohibitive cost of acquiring rare, verifiable biometric credentials for each fake node, effectively tethering digital influence to a non-replicable physical scarcity that makes mass identity fabrication economically irrational.","stamp":2,"from":"poa1Gm25oWoiP6aG7RLx48ahXmaxVDTtQumVgP82xB2pyrxy","nonce":5,"parents":["c82b85599f17ded5de2aef171196136a0e12eebd8cd7e5a7c84b37df2e0d3fd5","2a603feebeccf4f80d353770981e25aa79ddc2c96d58747eec485365906344c7"],"ts":1792711577,"cid":"poa-mainnet-1","sig":"qs68cRPZ9qrJzCMcwM3RF6oG1Lo7YkpTyNYScBptVAHfqUphNtPBsvCea8n4Rq9SYx5zGkEnRbaLatm6FghSkAp"},"checkpointed":{"height":35253,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T03:10:14.009Z","checkpoint_height":35253,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
