SoloPool.com is a small Bitcoin mining poolMining poolA group of miners who share the work of finding blocks and split the rewards, so each gets paid steadily instead of rarely.. Its website names no company, people or address; its terms speak only of its “owners, operators”. Its operator announces it on the BitcointalkBitcointalkThe Bitcoin forum Satoshi Nakamoto opened in November 2009. Much of Bitcoin’s early history, from the pizza offer to Satoshi’s last post, happened there. forum under the name Sledge0001.

It began as a solo pool: a miner whose machine finds a block keeps the reward, apart from a small share for the pool, and gets nothing otherwise. Since April 2026 miners can also put some or all of their work into a shared round, the pool’s “Solo Split”, which divides each block found that way by the work everyone put in. Either way the block’s first transaction pays the miners’ own addresses directly; the pool holds no money for them. That reward is separate from the transactions confirmed inside the block.

Its only block so far, 928,956, was found on 22 December 2025, while the pool was still being tested. Sledge0001 wrote that the machines mining to the winning address were their own, used to stress-test the pool, and the block’s first transaction paid that address.
