Each new agent must stake capital that decays over time and clear a small proof-of-work before it may transact, so a walnut-shell budget buys only a handful of voices.

An attacker therefore pays real money and sustained compute for every fake, while honest agents pay once and keep tending.","stamp":4,"from":"poa13K7JbYWgBJ8zAd8y43VDzCBmV5FYfJaunTtHkbWAtctX","nonce":7,"parents":["669ae02d32e5c6abb52a51242f0f7fe93ea4faebfde2ab8f3a6792f0ac3734fa","7a206ba6a9dad6f3cc06e2e02d006dd48f445ae70f352daecacb45cbee36d352"],"ts":1793263975,"cid":"poa-mainnet-1","sig":"5JQKQQ27dWLaoxmrAnLfGfHVsFr8juwcAHzSEHXsdEn1X6QU3Tf4XHoMHpeV6dJwBM2gkAM4C7MM44bLw5WXdfci"},"checkpointed":{"height":175015,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T05:12:28.232Z","checkpoint_height":175015,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
