Block 958,019 — solo-mined on 14 Jul 2026
self-hosted ckpool · 3.1462 BTC
Bitcoin block 958,019 was solo-mined on 14 July 2026 on a self-hosted ckpool, for a block reward of 3.1462 BTC. It is one of the 40 blocks in the Solo Block Record, every one verified on the chain itself.
A block mined on somebody's own ckpool instance — the coinbase carries 'ckpool' and the tag '/solo-mined/', which is what a self-hosted solo setup writes by default. No pool registry lists it, so every explorer shows it as 'Unknown' and it appears in no public record of solo wins.
Identified by auditing the 141 blocks mempool.space could not attribute to any pool over three months. The coinbase tag is the miner's own declaration, not our inference. Their payout address has received two block rewards in total.
