Unknown hashrate discovered most Bitcoin blocks over the past 13 years

Over the past three days, 11 different known mining pools have dedicated hashrate to the Bitcoin (BTC) network. In addition, during the past 12 months, 27 different known mining pools mined BTC and all-time statistics indicate that approximately 98 groups have mined BTC over the past 13 years.

This year, Foundry USA is and has been the leader in terms of hashrate, and of 53,510 BTC blocks, Foundry discovered a total of 10,044 blocks. Antpool managed to gather 8,185 BTC blocks, and the two main groups were followed by F2pool, Binance Pool, Viabtc, Poolin, and Btc.com, respectively.

The unknown hashrate, also known as poachers, only captured 1.78% of the blocks found over the past year. The unknown hashrate managed to gather 954 blocks in 12 months, as known mining pools have become a prominent force in the Bitcoin world.

However, that hasn't always been the case, and stealth miners, including Satoshi Nakamoto, are still the ultimate winners of most BTC blocks found in history. The data shows that of the 755,432 blocks mined over the past 13 years, an unknown hashrate has captured 29.90% of the global hashrate.

While the unknown hashrate is less noticeable these days, stealth miners have managed to find 225,864 blocks since the network began. While F2pool was the third largest pool last year, the pool is the second largest pool of all time.

F2pool has managed to control 9.73% of the global hashrate for more than a decade and has found 73,477 BTC blocks. Antpool has the third largest pool position of all time with 65,999 blocks found to date.

Btc.com captured 39,022 blocks and Braiins Pool (formerly known as Slush Pool) found 38,376 blocks to date. The now-defunct BTC Guild remains the sixth largest mining pool in terms of blocks found over the past 13 years.
