Texas Poised To Be A World Leader In Bitcoin And Blockchain
I write about blockchain regulation and policy.
Texas has seen the upside of China’s decision to cancel bitcoin mining, in what set off the ‘Great Mining Migration’ to Austin, Texas. The Texas Blockchain Council has grown to 70 members and is led by Lee Brachter, the President of the organization. And next Friday, he will be hosting the Texas Blockchain Summit – an event that could prove to be the largest state-level blockchain one-day summit ever.
It’s not lost what Bitcoin might do for Texas – already a top ten economy in the world With Senator Ted Cruz (R-TX), Senator John Cornyn (R-TX) and Senator Cynthia Lummis (R-WY) speaking at the event, could make the first Texas Blockchain Summit a benchmark for the amount of interest in how Texas could benefit from the growth of digital currencies and blockchain technology.
Texas Governor Greg Abbott has met with the Texas Blockchain Council twice already. Recently Abbott commented on Twitter that, “Texas will be the crypto leader. Cryptocurrency is now coming to Texas grocery stores.” Abbott was referring to the decision by H-E-B to put cryptocurrency kiosks in some Texas grocery stores.

President of the Texas Blockchain Association Lee Brachter stated “Texas is poised to become the jurisdiction of choice for blockchain innovation for several reasons including; the business friendly climate that has been cultivated in Texas for many years, the efforts of our Texas Blockchain Council working alongside lawmakers like Representative Tan Parker and Senator Angela Paxton to create legal and regulatory frameworks that allow for entrepreneurs to innovate.”
Texas House Bills 1576 and 4474 officially took effect on Sept. 1 after being signed into law by Governor Greg Abbott in June of 2021. Texas House Bill 1576 establishes a working group on blockchain technology. HR 4474 was a bill that updated the Uniform Commercial Code to recognize cryptocurrency and becomes the latest state – along with Rhode Island and Wyoming – to do so. Meanwhile, the Commissioner of the Texas Department of Banking issued a letter authorizing all Texas state-chartered banks to custody cryptocurrency.
Governor Abbott also appointed four new experts to the work group on blockchain matters. that includes a combination of professors from academic universities and Texas state officials. Texas has not slowed down in its ambitions either, as the Texas Blockchain Council, led by Lee Brachter, has rolled out the idea of a constitutional amendment that would allow the use of bitcoin to pay property taxes in Texas.
According to a recent article in Forbes, Texas has witnessed unbelievable growth numbers so far this century. “From an annual GDP of a little over $998 billion in 2000, the Texas economy has surged by 70.6% in 20 years, to reach an annual GDP of just under $1.75 trillion by 2020,” the article states. With the GDP size currently making Texas the 9th or 10th largest economy in the world, there should not be any underestimation with respect to just how large Texas could grow with crypto.
NORTH VANCOUVER TO BE WORLD’S FIRST CITY HEATED BY BITCOIN
Bitcoin mining company MintGreen to deliver innovative low-carbon mining waste solution to heat City of North Vancouver, BC.
As the price of bitcoin rises, bitcoin’s hashrate is also rising. Mining computers around the world are humming away and at the same time are producing amounts of waste in the form of excess heat that is unprecedented.
Enterprising miners like Burnaby-based MintGreen, a Canadian cleantech bitcoin miner, is already leading the waste reuse space with their heat sales to a local brewery and a sea salt distillery.
Other miners are using excess heat to power greenhouse operations (growing flowers and vegetables), home heating, and Jacuzzis.
Now MintGreen is getting into industrial sales with a 12-year contract to provide heat with their new “Digital Boilers” (which recover more than 96% of the electricity used for mining) to North Vancouver’s district energy system to heat commercial and residential buildings.
For MintGreen, heat recovery projects are a win-win as they get to reuse the initial hydro, for mining and for sale.
CITY OF NORTH VANCOUVER, BC
Located in the hills north of Vancouver, the City of North Vancouver uses a hydronic district energy system for heating that delivers heat to 100 residential and commercial buildings.
North Vancouver City council has taken the issue of climate change to heart and has set its own emissions reduction goals. According to their release:
“In 2019, the City of North Vancouver Council passed a motion for the city to increase its greenhouse gas reduction targets to achieve net zero by 2050 and reduce emissions by 80% below 2007 levels by 2040.”
Over the term of their contract with the city, MintGreen’s Digital Boilers will prevent 20,000 tons of GHGs from entering the atmosphere per MW compared to natural gas.
“The complex issue of climate change requires innovative solutions, and LEC, with the City of North Vancouver, is showing tremendous leadership in environmental stewardship.” said MintGreen CEO, Colin Sullivan in an announcement today.
LONSDALE ENERGY CORPORATION STEPS INTO THE FUTURE
The Lonsdale Energy Corporation (LEC) is owned by the city and has been providing energy here since 2003. LEC is working with the city to find ways to reduce its carbon footprint or decarbonize.
“The LEC is on a decarbonization journey to implement more renewable and clean energy, transitioning from the use of conventional natural gas,” says the announcement released today.
The city currently uses a mix of energy sources according to the website:
“LEC presently uses a combination of high efficiency natural gas boilers, ground source heat pumps, heat recovery from building cooling, and solar thermal panels to heat hot water.”
“LEC is continually exploring ways to use waste heat from buildings and industrial processes located adjacent to the district energy system and switching to alternative and renewable fuels. LEC will transition to using zero emissions energy sources as soon as it becomes economical to do so. This move is already underway in Central Lonsdale where LEC’s mini-plant is powered by solar energy.”
In the announcement today, LEC CEO Karsten Veng said.
“Being partners with MintGreen on this project is very exciting for LEC, in that it’s an innovative and cost competitive project, and it reinforces the journey LEC is on to support the City’s ambitious greenhouse gas reduction targets.”
Veng hopes that the MintGreen Digital Boiler pilot project could be the launchpad for future expansion opportunities as the City of North Vancouver continues to grow.
“Today’s announcement also mentioned the federal government’s proposed $170 per ton carbon tax coming into effect in 2029 which will drive up the cost of natural gas, another reason to cut carbon.
In an interview with Bitcoin Magazine, Sullivan told us that there isn’t any way that bitcoin mining could be greener.
Over 97% of BC Hydro’s energy mix is hydroelectric. Using that energy twice both eliminates waste and makes this project one of the greenest in the space, he explained.
Mining with hydro already makes MintGreen green and reusing that same energy to sell heat makes it that much more eco-friendly.
Samson Mow, CSO for Blockstream Inc who is acting as a special advisor to the MintGreen team, told us:
“MintGreen’s new innovation is a perfect example of how mining bitcoin can be the greenest use of energy on the planet”
Cryptocurrency is Heating Up, Literally: Offsetting Building Heat Needs with Cryptomining
In just a few years, the interconnected relationship between renewable energy and cryptocurrency have become a trendy topic on which to prognosticate, debate, and overreact. Depending on who you ask, cryptocurrency might be catastrophic for its massive energy requirements or be uniquely positioned to revolutionize the utility industry.
The cryptocurrency movement is still young and the degree to which it will become integral to the world economy, and thus its required energy needs, is still conjectural at best. But unquestionably, the energy-intensity of cryptocurrency mining and the general blockchain processes are important ones to examine as they could result in the trend sinking or swimming. Amid all this debate and speculation, the outside-the-box thinkers are instead asking how that crypto-energy can best be captured and utilized. If the computing power needs can serve dual purpose, then the mining process doesn’t needed to be considered benefit or bust purely on the cryptocurrency outcomes alone.
That’s where the Quebec-based startup Heatmine comes in. This company places its cryptocurrency miners— the computers used to generate Bitcoin and other digital currencies– in strategic locations for its clients so the buildings can benefit from the heat that comes off of them during the mining process. With miners that are capable of heating 300 square meters for 24 hours per day, what was once considered waste heat from the cryptomining process (even worse, heat that required additional air conditioning to cool down the space) has cleverly been turned into an asset to supplement heating needs, minimize power requirements, and effectively maximize cryptomining profits while minimizing its footprint on the energy grid.
I had the opportunity to learn more about this ingenious solution from Heatmine COO Jeremy Dahan.
In the Beginning
The idea behind Heatmine came to its inventors when Dahan and his partners realized that massive energy was being poured into cryptocurrency mining and such processing power naturally heated up the areas storing the computers. Thinking about this idea led to them to ask themselves “Can something be done with this waste heat?”
They approached that question in the classic brainstorming strategy of “no idea is dumb,” bringing out such outlandish suggestions as drying clothes or even heating oil to make french fries. The team eventually stumbled upon the idea of heating warehouses and greenhouses, and this thought was the one that really stuck.
In the six years since then, Heatmine has been completely self-financed and has spent much time and money to test, fine tune, and rework their combination mining/heating units to perfection. When asked about the challenges to this point, the COO indicated that the only real difficulty they’ve had thus far has been designing and fitting the water cooling loop onto the units in a manner that was reliably leak-free (water + computer processors = not the kind of cryptocurrency boom you want to see).
How It Works
The key to Heatmine’s41 successful implementation has been the realization that releasing ambient heat to its surrounding room or building wasn’t efficient enough, and instead the mining units could complement a building’s larger heating system. After developing prototypes and much testing, Heatmine units plug directly into existing heating systems using a hot water system. The heat generated by a Heatmine unit is used to heat up water that feeds into a building’s radiators, boilers, or water heaters.
Each mining unit gets built ahead of time at Heatmine’s facility before being directly shipped to clients. The team from Heatmine then installs the unit outside the building (installed either on the roof or on a concrete slab next to the building) and connects directly with the air ducts or hot water loops in a surprisingly straightforward process. From there, the miners are connected to the Internet and a power supply– neither of which require special equipment to be installed– and the Heatmine unit is off and running.
One Heatmine unit, which can be connected to any water heating system in Canada, provides 75,000 BTU per hour – which is enough to heat up to 300 square meters for 24 hours a day.
Among the areas on which the development team spent a lot of time was ensuring that the units were designed with serviceability in mind. Each Heatmine unit is compartmentalized so parts or entire units can be swapped out with ease, and they are also digitally monitored constantly to ensure the quick fixing of any problems that may arise.
Once in operation, a Heatmine unit will mine cryptocurrency 24 hours a day, simultaneously contributing its heat to the building’s heating systems and reducing power draw from the building’s heating needs. While the Heatmine units of course are a source of energy consumption, the power for them is paid entirely by Heatmine and the energy being consumed is going to the cryptocurrency mining process that otherwise would have generated wasted heat if installed anywhere else. As such, the use of Heatmine to serve the dual purposes of cryptocurrency mining and heating is a net win in energy use, energy efficiency, and associated carbon emission reductions.
The Business Model
Heatmine’s operations aren’t just innovative for the technology they’ve created, but the business model is quite clever as well. The relationship between Heatmine and its clients is a symbiotic one. The client receives the heat generated to offset their typical full heating needs at no cost to them, reliably saving them on their monthly power bills. For their efforts, Heatmine collects the proceeds for the cryptocurrency mining process itself (note that this setup is one that may change in the future, or Heatmine might provide additional arrangement options as they grow). This endeavor remains profitable by minimizing the overhead costs of typical cryptocurrency mining operations, from cooling all the waste heat to housing the units. By outsourcing that overhead to its client, Heatmine creates a mutually beneficial arrangement.
When it comes to the cryptocurrency they’re mining, Heatmine takes advantage of flexibility with the exact coin on which they choose to focus. Their research team investigates specific opportunities, selects coins, and installs the necessary software in their units. Dahan notes “We mine multiple coins and can change many times in one day. A big winner lately has been Ravencoin.”
For their entire product and service, Heatmine is currently working on the patent process. While other companies have dipped their toes into the idea of using otherwise wasted heat from cryptocurrency in other ways, those have only completed testing in private environments and haven’t shifted towards mass production like Heatmine is preparing to do.
Successes with Heatmine
Heatmine is only really beginning to expand and implement their two birds with one stone solution to a wider potential customer base and spectrum of applications. This season, they started their first winter test of 15 units, including deploying units at a greenhouse, private home, and several warehouses.
The greenhouse application was an early success for Heatmine, touting specifically a strawberry greenhouse in Canada that benefited from the heat output of Heatmine’s cryptocurrency operations. Through this partnership, the owner of the greenhouse noted that they “were able to significantly reduce production costs and were as competitive on prices as Mexican strawberries.” Overall, though, Dahan and his team from Heatmine recognize that there are far more warehouses than greenhouses in Canada and these will represent the area in which they can make the most impact.

As with many energy efficiency and clean tech solutions, this user’s positive reaction epitomizes the idea that efficiency and embracing outside-the-box sustainability solutions aren’t just feel-good projects. Rather, these decisions have inherent economic benefits and can bolster the bottom line, no matter whether the intent is green for the environment or green for cash.
Further, this type of heating has the capability to be extremely clean based on the energy mix of the region in which the Heatmine units are currently installed. While almost half of Canada uses gas for heating, which is a significant source of emissions, Heatmine’s miners source the power entirely from the electric grid. If the energy mix of a region’s grid is particularly clean, such as Quebec and its nearly 100% renewable energy, then the heating contributions from cryptomining are similarly clean. Even further, the cryptocurrency was likely to be mined elsewhere anyway, meaning without such a setup the same amount of power would be drawn elsewhere with the heat generated going to waste. Worse yet, that alternative location of mining might have been cooled with air conditioning, meaning the impact to heating energy loads is double.
For all the excitement, it’s of course worth noting that Heatmine is still a young and relatively modest operation, but they’re continuing to grow and are by no means thinking small. Over the course of this next year, they’re focusing on building up to 750 units, which would translate to the decentralization of 50,000 GPUs and processors– directing their heat to where it can be utilized and offset energy demand.
COO Dahan notes that Heatmine sees immense opportunity for growth in the Canadian region that’s their only home right now. According to Dahan, “This is our focus. For now, we don’t plan to export or sell the product. What we want is to choose the perfect partner to help with our free heat.” The market for this product in Canada is potentially huge, and their goals for now are to focus their entire efforts on the region. Heating is, of course, a premium need in the cold weather of Canada and Heatmine sees the warehouse heating needs being especially lucrative.

In the long term, Heatmine is looking to improve their assembly lines to be able to produce 10 Heatmine units per day, which would allow them to reach 15,000 units over 5 years. That sort of production could allow them to capture and offset 1% of the heat needs of the Quebec province all on their own. That figure may sound small in the grand scheme, but given the deployment of their product is a bona fide win-win (both economically and with regards to energy) that would represent an ingenious and successful implementation of sustainable solutions.
Dahan closed out our discussion optimistically noting “We are constantly researching how we can add revenue streams and more computing services can be built on the Heatmine network– such as cloud computing, AI, and more!” With an outlook like that, Heatmine looks to be a powerful force in the coming years.
