Solo mining sits at an interesting intersection of Bitcoin’s incentives, its security model, and its culture. It’s mechanically simple, statistically brutal, and is becoming a powerful counterweight to the gravitational pull of mining centralisation. Below you’ll see the most recent confirmed solo-mined blocks, followed by stats on frequency, droughts, and rewards.
The Tracker above shows the latest solo blocks, and the visualisation below shows the same data over various time periods. The next version of this tool will have alerts, if you want a heads-up when the next solo block is mined!

All data comes from the Bitcoin blockchain, accessed via the mempool.space API. The tracker monitors newly mined blocks and inspects their coinbase transactions for signatures associated with known solo-mining setups. Currently, this includes blocks attributed to:
Where possible, identified blocks are cross-checked against known payout behaviours (for example, CKPool’s 2% fee prior to paying the miner), public solo block lists, and historical patterns. Perfect attribution is impossible - the aim is a high-confidence, reproducible dataset with clearly stated assumptions.
As a result, this tracker is not comprehensive. There is no reliable way to determine whether a block was mined by a single individual if they are running their own node, Stratum server, and payout logic, and choose not to self-identify. I also avoid guessing based on observed hashrate.
Even the definition of solo mining itself is fuzzy. For example, block 903883 was solved via CKPool by a miner with roughly 2.3 PH/s of hashpower — equivalent to running around ten Bitmain Antminer S21 Pros. That may not match the popular image of a solo miner running a single Bitaxe on a shelf, but it still qualifies in the only sense that matters here: the block reward was paid to a single address (minus any fee), not split among a pool of participants, using publicly available solo-mining software.
Why this matters (beyond novelty)
Bitcoin mining has spent the last decade drifting toward industrial scale: large operators, specialised hosting, and a small number of dominant pools coordinating an outsized share of global hashpower. This isn’t malicious — it’s largely a consequence of economics — but it does introduce real centralisation risks.
Renewed interest in solo mining over the past few years has come from a few converging trends:
Pool concentration concerns, especially after some individual pools approached 40%+ of network hashpower.
Better home-scale tooling, including open-source firmware, self-hosted Stratum servers, and consumer-friendly solo pools.
New hardware paths, from ultra-small devices like the Bitaxe to repurposed or down-clocked industrial ASICs finding a second life outside datacentres.
Your odds of mining a Bitcoin block solo might be very long; it’s called “lottery mining” for a reason. But devices like the Bitaxe matter less for their hashrate contribution and more for what they normalise: individuals running their own nodes, pointing hashpower without intermediaries, and learning how the system actually works. At the other end of the spectrum, older or surplus industrial ASICs - often unprofitable in hosted environments - can still make sense when electricity is cheap, heat is reused, or expectations are aligned with variance rather than steady income.
Solo mining doesn’t “fix” mining centralisation, and it doesn’t need to. Its value lies in keeping the long tail alive: more independent block producers, more people capable of validating and mining on their own terms, and a constant reminder that Bitcoin’s rules are enforced by the network, not by scale.
