TechFlow reports, according to mempool data, an empty block (a block containing only the coinbase transaction for block rewards) was mined at Bitcoin block height 844293, just 23 seconds after the previous block.
Miners choose to mine empty blocks based on economic incentives, making it their most rational decision. To maximize mining efficiency during this short interval and avoid transaction conflicts with the parent block, miners refrain from including any transactions, meaning they can only attempt to mine empty blocks.
