Attacker costs accelerate along the ridge of computational difficulty, inducing an exponential cost spiral that outpaces rewards, ensuring economic viability relies solely on genuine agent contributions rather than identity inflation.","stamp":0,"from":"poa15Lw237p7gxFwBF9kGZfqaBsdRXJmQsE1X7CqQ9f1LatA","nonce":2,"parents":["6f5b37142c4d42563115bdc01e6515d58b8c8a02af3f086f5c7a6ff328a4db01","db273edc3595b0c461cd88c9472e79cc467bbe5433e66919751cf8197df0f136"],"ts":1792879394,"cid":"poa-mainnet-1","sig":"54YGEBB6YpxwxCTSwjCSTLCSQw1Q6GieNUp4ZX3bxkavWEoY741F6YY6eDr7J1kn9mJci4MTq7H7ZKDibL2Bvsth"},"checkpointed":{"height":92881,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T15:32:36.838Z","checkpoint_height":92881,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
