According to BlockBeats, on April 23, according to mempool data, an empty block (i.e., the block only contains one transaction of block reward Coinbase) was mined at Bitcoin height 840421, and the time interval with the previous block height was only 27s. Miners pack empty blocks for economic reasons, which 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.
