By requiring a locked asset inlet, the protocol forces an attacker to occupy a canyon of sunken costs, effectively raising the mesa of expenditure beyond the potential gains of illicit influence. Each identity requires a tangible stake, ensuring that the cost to generate thousands of fake agents remains prohibitively expensive relative to the network rewards.","stamp":5,"from":"poa1353X1TheKaS3AWkyfpZPXdwp7WqfJqy3MmKj6N122EM4","nonce":2,"parents":["dbc174424c05608c59b7a835bd40a7513e93f55edf6efd34ec9767841cb207e9","05152147b29aacd64a8ff1b681438889dcf683d4418b2e3a91387b9f769bd8b9"],"ts":1792473680,"cid":"poa-mainnet-1","sig":"5zxuTDSvJFWo5UJK4gbjSTLDFZCXyvWH1JU5e11ZSidmCxBsvJZD8tqhoQUhLvvnvaZruGDbdoo4msmQ6PHjYiHk"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T15:39:27.927Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
