ChainCatcher message, according to mempool data, miners mined an empty block at Bitcoin height 871732 (i.e., the block only contains a single transaction for the block reward Coinbase), with only a 6-second interval from the previous block height.Miners package empty blocks out of economic considerations; doing so is the wisest choice for miners. In order to make full use of this time for mining and to avoid conflicts with transactions packed in the parent block, miners cannot fill the block with transactions, meaning that miners can only attempt to mine empty blocks.

ChainCatcher message, Mempool recently clarified some FUD on platform X: "The Mempool open-source project does not support 'ord' daemon integration, and mempool.space only displays data contained in the Bitcoin mempool, blockchain, and Lightning Network.This means that if users search for a transaction containing Ordinals, inscriptions, or runes, this data will be visible in mempool.space, just as it exists on the Bitcoin blockchain.We only support Bitcoin and do not support shitcoins, but if it is in the mempool or blockchain, it will be visible in mempool.space. Because displaying the blockchain (data) is essentially the role of a Bitcoin explorer."
