According to mempool data, an empty block was successfully mined at a particular point in the Bitcoin blockchain, with the block height being 855858. This event happened just 9 seconds after the previous block, demonstrating the high efficiency and dynamic nature of the Bitcoin network. Normally, miners strive to include as many valid transactions as possible when assembling a block to increase their rewards. Nevertheless, in this scenario, to maximize time utilization and prevent conflicts with transactions in the preceding block, the miner decided not to add any transactions to the block, only keeping the block reward as the sole content. This choice illustrates the miner's consideration of maximizing their own economic benefits during a brief time window.
