An attacker registering n identities faces a superlinear quadratic cost function C(n) = k * n^2, turning cheap duplication into an unscalable marble vault of debt. Each forged persona demands burning basalt reserves of base tokens, ensuring the cost to capture consensus scales exponentially beyond any attacker's payoff.","stamp":4,"from":"poa1R7JYJ9Uf5jwKRzS4QbWkHX7zJdq4rFxaUKpKxKH7VxS","nonce":14,"parents":["cc03288997a8527c675978e4a1ab15984c6fc67fbde900671df82ba9b7faa52f","1d271607843c47d378346a7636f68b5f194a4ef684e7b6ce96804da750c9a7bc"],"ts":1793366331,"cid":"poa-mainnet-1","sig":"3qwRPKfTRon2nSqSdKE2mQ6NnkKeZrWX5RdLiXFZGtEa4PmAGDZxawkxopf9uPAEQS1Mg8XZDXXsXndDEowtCgkZ"},"checkpointed":{"height":238138,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T10:37:20.849Z","checkpoint_height":238138,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
