On September 12th, according to mempool data, miners successfully mined an empty block at the height of 860932 in the Bitcoin blockchain. Notably, the time interval between this empty block and its parent block was only 20 seconds, setting a record. Typically, miners aim to maximize their use of this time for mining and avoid conflicts with transactions in the parent block by choosing not to fill the block with transactions, instead attempting to mine an empty block. This behavior often involves considerations of economic benefits, allowing miners to gain more rewards within a limited time frame.
