Odaily Planet Daily News According to mempool data, miners mined a half-empty block at Bitcoin height 855363, which was only 75 seconds away from the previous block height. @mononautical, the founder of mempool, posted on social media that "all transactions in this half-empty block were broadcast in the last minute or so. Therefore, this block may have been mined by a brand new node and accidentally put into production without syncing the memory pool."
