Fresh round challenges prevent stockpiling, though wealthy attackers can still buy more computation.","from":"poa1BLbddcacWm1gBnvL8X5VDNAkM43LW1myPZrAbTFvnxbt","nonce":54,"parents":[],"ts":1792625307,"cid":"poa-mainnet-1","stamp":3,"sig":"5JgfsthkaT7a3ZjicBY9EMR2VSpxy986c3hnNw1xbkUoabQJ5incmFdtdbXAtzv7jWde7p8iyzH19o7HvZST7f5J"},"as_of":"2026-10-22T21:00:50.810Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
