Bitcoin blocks mined by unidentified entities now top nearly a quarter of all blocks ever created on the network. According to data from Cloverpool, an entity marked as “unknown” has mined 230,770 blocks, accounting for 24.03% of the blockchain’s total. This category surpasses well-known mining pools like Antpool and F2pool in total blocks found.
Who Are the Unknown Miners?
The “unknown” label includes two distinct groups. First, it covers solo miners and smaller operations that never included identifiable tags in their coinbase messages, leaving their blocks unattributed. Some miners leave this field blank or use generic text, which means blockchain explorers cannot link these blocks to any specific pool or operator.
Second, this group contains blocks from Bitcoin’s earliest days, before mining pools were established. This period includes the work of Bitcoin’s creator, Satoshi Nakamoto, who mined independently using a home computer in 2009 and early 2010. Researchers estimate Nakamoto controls roughly one million BTC based on early block reward patterns that remain untouched.
Antpool ranks second with 109,004 blocks mined, making up 11.35% of the total. Founded by Bitmain to support Antminer hardware users, Antpool has been operating independently overseas since 2021. F2pool follows closely in third place. Meanwhile, some pools like Poolin have faced recent financial troubles, filing for Chapter 11 bankruptcy in New Jersey after halting operations in Texas.
Despite shifts in the space, the dominance of early solo mining and non-attributed blocks remains significant. This highlights the historical depth of Bitcoin’s mining ecosystem, where individual contributors and small operators still hold a prominent legacy alongside large industrial pools.
