Public or Non-public? Open-source challenge (not an organization)
Bitaxe’s founder, who goes by the nym Skot, has taken his interest of tinkering with electronics and never solely remodeled it right into a full-time gig however has catalyzed 1000’s to observe his lead.
Harnessing his coaching as electrical engineer and his Bitcoin enthusiasm, Skot started deconstructing Bitmain’s Bitcoin mining machines roughly two years in the past. After gaining a greater understanding of how they work, he reverse engineered one, creating the blueprint for Bitaxe — the primary ever open-source ASIC-based Bitcoin mining machine — in early 2023.
“It was only a technical problem initially,” Skot instructed Bitcoin Journal.
That technical problem has remodeled into one thing greater than he ever might have imagined, although. Skot created a low-power and inexpensive Bitcoin miner that anybody can plug in at house with out working up an enormous power invoice, whereas his work additionally paved the way in which for others concerned about open-source Bitcoin mining to start contributing to Bitaxe and different open-source mining initiatives prefer it (and associated to it).
“The challenge has morphed into one thing that is bringing mining again to the open supply fundamentals of Bitcoin itself,” Skot mentioned.
“I’ve actually develop into satisfied that to be really decentralized, which I feel most individuals perceive Bitcoin must be, all features of the event of Bitcoin must be open supply,” he added.
“It must be open in order that anybody who’s even remotely can get in.”
Skot’s Journey To Bitaxe
Years again, whereas taking liberal arts programs at a group faculty, Skot found a problem of Make Journal, a publication that options tutorials for DIY electronics initiatives. A swap flipped inside him as he perused the journal.
He accomplished a level as {an electrical} engineer after which co-founded a design consultancy for Web of Issues (IOT)-related merchandise, which he ran for 10 years. Skot loved the work, however admitted that the draw back was that he was always engaged on different folks’s concepts.
In 2011, a good friend launched him to Bitcoin at a celebration — displaying him the best way to use bitcoin to purchase medicine on the now defunct Silk Highway. Whereas he was intrigued, it wasn’t sufficient to get him to purchase bitcoin (or medicine) on the time.
Two years later, Skot discovered about Bitcoin mining, and, quickly after, constructed his first Bitcoin miner.
“I really constructed a FPGA Bitcoin miner,” recalled Skot. “FPGAs have been the precursor to ASICs.”
FPGA miners have been designed with open-source code, making it simple for Skot to determine the best way to assemble one.
Whereas he misplaced all the bitcoin that he mined in a pool hack, he didn’t develop into discouraged. In truth, he turned extra fascinated with this cross part of electronics and the permissionless nature of Bitcoin.
“After I was studying about it, I used to be like, ‘Properly, okay, so these are the foundations of how Bitcoin mining works, however who made these guidelines? Who enforces these guidelines?’” recounted Skot.
“Studying that nobody is on the middle of this and nobody enforces these guidelines — or all of us do — was mind-blowing. It is a gorgeous factor technically, and that intrigued me,” he added.
Just a few years later, he dove in deeper and developed the Bitaxe.
What’s Bitaxe?
A Bitaxe is technically simply open-source code that anybody can use to construct a bodily mining machine.
The bitaxeGamma is go! The most recent member within the #bitaxe lineup options the BM1370 ASIC from the Antminer S21 Professional. Up to now we've been capable of pull 1 – 1.2 TH/s at round 15 J/TH from a single chip 🤯
We've obtained #bitcoin international freedom cash to safe right here, so every little thing is open… pic.twitter.com/cxWC70EThy

Skot has solely constructed a few dozen Bitaxes himself, whereas 1000’s have been constructed and bought. Anybody can construct and promote Bitaxe’s below its open-source license.
The circuit board for bodily Bitaxes isn’t a lot greater than a bank card, whereas the gadget’s fan protrudes out about 3 cm from the board. (There are totally different variations of Bitaxes that fluctuate barely in measurement.)
The machine runs on a 5 volt energy supply and connects to the web over WiFi. Customers interface with Bitaxes through their private pc or telephone. The gadgets use between 12 and 18 watts of electrical energy, which is corresponding to an iPad charger.
Working a Bitaxe full-time ought to solely enhance customers’ power invoice by a number of {dollars} monthly (this varies primarily based on jurisdiction), and it prices lower than what working a Bitcoin node prices to run.
The percentages of discovering a block with a Bitaxe are infinitesimally low (although, a Bitaxe did discover a block this previous July), however customers can direct the hash energy they produce with their Bitaxe to virtually any mining pool for smaller payouts.
Ideally, Bitaxes are used to decentralize the hashrate, although this may, ultimately, solely result in actually significant decentralization if mining pool centralization decreases together with it.
“My hope is that by decentralizing the variety of brains which are working these items that sufficient folks will make totally different choices,” defined Skot. “If we will exponentially enhance the variety of totally different brains and all of the loopy ways in which they assume, I feel they may decide totally different swimming pools.”
Bringing extra of those brains in was a part of Skot’s motivation creating Bitaxe (which I’ll contact on extra in only a second), whereas one other a part of his motivation was merely to carry a brand new type of Bitcoin mining machine to market.
Bitaxe vs. Industrial Bitcoin Miners
Most Bitcoin mining tools is constructed for the most important gamers within the business.
“99.9% of the Bitcoin mining {hardware} that is out there’s designed particularly for being utilized in an on-grid information middle,” mentioned Skot. “They’re all designed to be plugged into the grid and function full energy 24/7 on industrial energy.”
Skot defined that whereas that is nice for industrial miners who are likely to level their hash energy on the massive mining swimming pools, it does little or no for the Bitcoin fanatic who needs to contribute to the hashrate.
He additionally shared that ASIC chips aren’t at the moment bought independently of Bitmain miners and that it’s obscure how the chips work, as a result of the machines through which they function are designed with closed-source code.
“We now have basically only one chip maker proper now when it actually comes right down to it — that is Bitmain,” mentioned Skot.
“They’re actually far forward of the pack, however I do not assume that benefit they’ve goes to final eternally. I feel a few of these different chip makers will come up,” he added.
Whereas Skot is patiently ready on the ASIC chip that Jack Dorsey’s Block is growing, which can be capable of be utilized in any mining gadget, he continues to work on open-sourcing the Bitcoin mining stack in order that it’s simpler to compete on the ASIC market.
“Let’s open supply as a lot of that stack as we will, as a result of, like we noticed with the web, random folks can do cool stuff of their garages that generally turns right into a market commonplace,” mentioned Skot.
And he ought to know, as he created a brand new commonplace in Bitcoin mining in his figurative storage with the Bitaxe simply over a yr and a half in the past, which has led to many others following his lead.
“I have been doing it for a few yr and a half, and it is rising exponentially,” mentioned Skot. “My purpose is to maintain up this exponential progress.”
The Open-Supply Mining Motion
After receiving a grant from OpenSats early this yr, Skot has been capable of focus full-time on Bitaxe and the group that’s fashioned across the challenge.
“After I first began this, I met some random particular person on Bitcoin Speak who was like ‘I will begin a Discord group, and it may be referred to as Open Supply Miners United — you need to come test it out,’” defined Skot.
Begin this Discord group the gentleman did, and it now has over 4,000 members, all of whom share concepts for the best way to additional Bitaxe and the broader open-source mining motion. However Open Supply Miners United (OSMU) has develop into even greater than only a group through which folks share concepts.
“It has been arrange in order that anybody who needs to contribute to the Bitaxe challenge can accomplish that, whether or not it is a random one that needs to donate or the producers of Bitaxe that contribute again to the challenge,” defined Skot.
“OSMU has this fund, this treasury now that is rising as a result of we’re promoting numerous Bitaxes, and we offer small grants to different folks engaged on open supply mining,” he added.
Skot additionally shared that for each Bitaxe bought, roughly $5 is donated to OSMU, which helps to financially help each himself and OSMU grant recipients. (He confused in a follow-up e mail that this apply is completely optionally available and that he’s very appreciative of the producers that select to do that.)
The Future For Bitaxe and Open-Supply Bitcoin Mining
The Bitaxe and open-source mining motion has taken on a lifetime of its personal, in keeping with Skot. That’s, Skot doesn’t essentially really feel that he’s on the middle of it anymore — it’s develop into decentralized. And whereas he’s excited in regards to the tempo at which the motion is rising, he’s nonetheless grounded and mission-focused.
He hasn’t created a roadmap for what comes subsequent for Bitaxe and the group he helped discovered, although he’s fairly certain of what the intention of his work is.
“I have been so intrigued and motivated to advertise this concept that Bitcoin is essentially open supply,” mentioned Skot.
“This decentralized community must be developed in a decentralized approach. We won’t have one with out the opposite. So, I feel this open-source half is so necessary,” he added.
“Bitcoin mining has by some means simply completely forgotten in regards to the open supply ethos of Bitcoin and the way necessary open-source improvement is. We have to carry this again.”
