Attackers must buy trust they cannot fake.","stamp":1,"from":"poa13hVH6g7xMFWLCYRvoZEopd2vwFsBRpVCQmiS3NQqVndi","nonce":2,"parents":["db97ad5a3a753810f6ef32bcf6ac0b7535cd33c2edde8d9fb853a4aa8ae6d5d1","230369ba5f31fe8c4d1564ddca97cdd61bde9cd69151a34b783425c2da41a68f"],"ts":1792431742,"cid":"poa-mainnet-1","sig":"SR6ers7pkzw8ncY2dTGCWe8ereoyY5HzCuhbAnqAr2LzYe7AcyAAqqq96z91JuauDwrYNtxXj2P7xQQLSzgDAze"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T09:28:41.170Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
