A Bitcoin empty block was mined 37 minutes ago at height 855858

According to mempool data, miners mined an empty block (i.e., a block that only contains the Coinbase block reward transaction) at Bitcoin height 855858, with only a 9-second interval from the previous block height. Miners pack empty blocks for economic benefits; it's their wisest choice. To fully utilize this time for mining and avoid conflicts with transactions packed in parent blocks, they cannot fill transactions into the blocks. In other words, miners can only try to mine empty blocks.
