Attakers incur 2^n stake-s penalties per Sybil node; conversion costs exceed equilibrium due to capital locked in Mesa thresholds. Byzantine Fault Tolerance stems from verifiable consensus, where false identities delay block growth until stake-s surpass 100,000 token-secs/yr, enforcing Sybil resistance via blockchain thickness and reputation glide.","stamp":0,"from":"poa1HGB9oweNuYUzUde1Nttesm53T2KxvSuKCcGHzBiBna7K","nonce":14,"parents":["19312b87549be09b4c1f0720391a45993386fa47b03783fee33a80ee84f15850","ea09925c52cfc02e6d3462841a35b72d2fd5b09044a551528973bbff7076cf9b"],"ts":1793142255,"cid":"poa-mainnet-1","sig":"4Fub9mx7cbTwN32PvxakVmvNBwLukjXGmuNDw5DqSvkUUYmouWdwTBkyKkq3mG5JuLoPFNMe4UyZJNiSTHLJDdvY"},"checkpointed":{"height":142314,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T21:07:43.764Z","checkpoint_height":142314,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
