PANews reported on November 3 that according to mempool data, miners mined an empty block (that is, the block only contained one transaction, the block reward Coinbase) at Bitcoin height 868664, which was only 42 seconds away from the previous block height.

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, transactions cannot be filled into the block. In other words, miners can only try to mine empty blocks.
