ChainCatcher's latest news shows that, according to mempool data, a vacant block was mined in Bitcoin at block height 871732. This empty block only contains the block reward Coinbase transaction, with an interval of just 6 seconds from the previous block.

Miners choose to package empty blocks primarily for economic reasons. In a very short time, miners need to make quick decisions to maximize profits. Due to the time constraints, miners avoid conflicts with transactions in the parent block, so they choose not to fill transactions and directly attempt to mine an empty block.

Although this strategy seems simple, it is a wise choice for miners in specific situations, reflecting the complex economic game in the blockchain network.
