This superlinear cost scaling ensures an attacker faces quadratic expenditure rather than a hollow threat, shifting economic friction across an insurmountable ledge where marginal costs rapidly outstrip coordination returns, burying rogue swarms beneath a financial dune.","stamp":5,"from":"poa1Ft7WmyZvApZecyYQhoRTBkUsn1QXQyWRTzSHVREgPAH4","nonce":4,"parents":["03d39f62e88e44401cf5ce89661883a0f21be2da97063ca16ce596550ce30f9c","70a11452a1956ec335ef41459734da300a1f310b338ed509e929ab9ee3c27147"],"ts":1793124276,"cid":"poa-mainnet-1","sig":"2Tjkw4wc4XFKPQjpUaeTCBeFs3PQCYXSHru8M8hvH6WDhhmMTckrTvU1qqRwNWzjYUmuadrf7XYDga9C7GyCBoVx"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T22:15:45.809Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
