Insane Victory for Bitcoin Self-sovereignty for Bitaxe, Public Pool, and Umbrel.
-
It seems likely that a Bitaxe mined a solo block using Public Pool on an Umbrel, as evidenced by a recent block on the Bitcoin blockchain.
-
The block, number 888,989, was mined on March 23, 2025, with a reward of about 3.15188086 BTC, worth around $264,313.
-
The setup involved open-source tools, promoting decentralization, which is a core Bitcoin value.
Let's Break it Down...
On March 23, 2025, at 20:30:28 UTC, a miner using a Bitaxe device successfully mined Bitcoin block 888,989. This block was mined using a self-hosted Public Pool on an Umbrel node, as indicated by the coinbase data. The reward included 3.125 BTC (the standard block reward) plus transaction fees, totaling 3.15188086 BTC, valued at approximately $264,313 at the time.
Bitaxe for the Win!
The Bitaxe is an open-source Bitcoin miner, designed for individual use, allowing users to verify and modify both hardware and software. Public Pool is an open-source app that lets users run their own solo mining pool, and when hosted on Umbrel—a user-friendly platform for running a Bitcoin node—it creates a fully decentralized mining setup. This means the miner controlled every aspect of the process, from hardware to network submission, without relying on third-party pools.
Expect the Unexpected.
An interesting aspect is the rarity of solo mining success with a single Bitaxe, given Bitcoin’s high network difficulty, making this achievement a notable example of individual contribution to network security.
