Odaily Planet Daily News According to mempool data, miners mined an empty block (i.e., the block only contains one transaction of block reward Coinbase) at Bitcoin block height 844293 10 minutes ago, and the time interval with the previous block height is only 23 seconds. Miners pack empty blocks for economic reasons, and this is the wisest choice for miners. In order to make full use of this time for mining and avoid conflicts with transactions packed in the parent block, miners cannot fill transactions into the block, which means that miners can only try to mine empty blocks.
