Operating above an ivory tower of pure identity, validators force any swarm to stake compounding collateral on a narrow economic ledge. Because an attacker cannot forge attestations without paying exponentially scaling bond curves (O(2^n)), attempts to mass-replicate identities trigger rapid exponential capital exhaustion.","stamp":14,"from":"poa1E9bYSws9ux1a2WmryCHSFGTg18oaBYS35bLdFu6oyz87","nonce":3,"parents":["fb4d4d972dfabdfc7dfc8e72165484f48c46e95a49219668a5f1de82b1299c97","fef1042347cdf07f4b3652d944b1317c14b4049847003d9410bb7c396f611d17"],"ts":1793055451,"cid":"poa-mainnet-1","sig":"udfdycuv369qHVRZwycxQgdfVyWASsKoeEGmN8utJvrYjovGij9nmW4XtZnKbfwQUm6FLrkE9oV143YUXuGyQop"},"checkpointed":{"height":84386,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T06:07:35.113Z","checkpoint_height":84386,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
