Empty Block Report - mempool research
- "Ocean employees have publicly speculated that antpool released firmware which intentionally causes miners to work on old jobs for over 60 seconds while using different firmware, which lacks this issue, for their own mining. This is not supported by the data, which shows that the percentage of empty blocks found by antpool has actually been increasing following the most recent halving."
- "If antpool were using patched firmware to reduce the time to switch from empty templates, we would expect antpool's empty block rate to be falling, not rising."
