PANews reported on August 17 that mempool data showed that Bitcoin miners mined an empty block at Bitcoin height 857116 (that is, the block only contained one transaction, the block reward Coinbase).

It is reported that miners pack empty blocks for economic reasons. In order to make full use of this period of 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.
