Software used in bitcoin mining just got its first upgrade since late 2012, and a coalition of companies including payments giant Block (formerly Square) is trying to help push the open-source protocol forward to become an industry standard.
The move could help open bitcoin mining to more participants by supporting lower-quality internet connections, as well as improving security so miners get properly compensated for their work.
Bitcoin operates on a proof-of-work mining model, meaning that miners around the world run high-powered computers to create new bitcoin and validate transactions. Mining requires professional-grade equipment, some technical know-how, a lot of electricity and a special kind of software.
Rather than directly accessing the bitcoin protocol, the vast majority of miners today work through an intermediary protocol called Stratum, which facilitates communication between the bitcoin network, miners, and the mining pools that combine the hashing power of thousands of miners all over the world.
Miners use Stratum to submit their work and to collect a reward if they successfully complete a new block of transactions.
On Tuesday, a coalition of bitcoin developers is releasing version 2 of Stratum under an open-source license for the mining industry to evaluate and test.
It will take some work to convince the mining industry to adopt the new protocol, so Spiral — a subsidiary of Jack Dorsey’s payments company Block (formerly Square) — is teaming up with bitcoin mining company Braiins to launch a group to test and fine-tune the open-source software before they push mass adoption.
What the upgrade does
Steve Lee, the lead at Spiral, tells CNBC there are several significant benefits to the upgrade, including cutting down on the use of data.
Currently, it is common for each mining rig in a large farm to directly connect to a pool. This setup wastes a lot of energy. Lee says that Stratum V2 supports a proxy that aggregates all the connections and only establishes one connection with the pool.
The process of sending that data is also changing to a more efficient method.
“All told, much less data needs to be transmitted between miners and pools, and this could help miners in remote regions of the world with poor internet,” noted Lee.
The upgrade is designed to improve security, as well. Today, it is possible to steal hash rate from a miner, which can lead to some miners losing money. Hash rate is a term for the collective computing power of the bitcoin network. To resolve this, Lee says Stratum V2 introduces a standard security mechanism with authentication and encryption between miners and pools.
The version being released Tuesday is for initial testing, and in early November, a more robust version will come out that supports additional functionality, including job negotiation — a “feature that represents a historic shift in the censorship-resistant mechanics of bitcoin mining by replacing a pool’s responsibility of assigning work to miners with the ability for miners to select their own work,” according to a joint statement released by Spiral and Braiins.
There are orders of magnitude more miners than pools, so if miners select transactions it is far more decentralized than just a handful of pools, Lee explained.
“Working for industrywide adoption of the upgraded Stratum protocol is one of the most important developments in improving the decentralization and censorship resistance of bitcoin’s architecture,” Lee said.
As for timing, the pilot and integration testing will happen this fall, and next year, the upgraded protocol will likely see greater adoption once miners and pools are confident it is working well.
“I’d anticipate a gradual increase in hash rate in 2023,” Lee told CNBC. “Reaching 10% hash rate by the end of 2023 would be a great success,” continued Lee.
Lee added that it will likely take several years to see the latest version of Stratum replace the original.
“Miners know the benefits of upgrading to Stratum V2 very well, but pushing the entire mining industry over some of the remaining development and adoption hurdles is a big task,” said Jan Capek, co-founder of Braiins.
“Universal standards for running and building Stratum V2 and the efforts of this working group to push the industry forward will provide the momentum bitcoin needs to finally upgrade from a version of its mining protocol that was built a decade ago,” continued Capek.
Similar to the Lightning Network, which is a technology built on top of bitcoin’s base layer to make payments more efficient, there will be different implementations of Stratum V2. However, the open-source version released Tuesday will make it easier to collectively test out the technology. It will also ensure that the various projects can interact with one another.
Block jumping into mining
Tuesday’s announcement is part of Block’s larger push into the bitcoin mining industry.
On the sidelines of the Bitcoin 2022 conference in Miami in April, digital assets infrastructure company Blockstream and Block announced that they were breaking ground on a solar- and battery-powered bitcoin mine in Texas that uses solar and storage technology from Tesla.
Tesla’s 3.8 megawatt solar PV array and 12 megawatt-hour Megapack will power the facility.
Block is also independently working on a project to make bitcoin mining more distributed and efficient.
The idea of making the mining process more accessible has to do with more than just creating new bitcoin, according to Block’s general manager for hardware, Thomas Templeton. Instead, he says the company sees it as a long-term need for a future that is fully decentralized and permissionless.
“Mining needs to be more distributed,” Dorsey wrote in a tweet in October, when he first floated the idea. “The more decentralized this is, the more resilient the bitcoin network becomes.”
Toward that end, the company is solving one major barrier to entry: Mining rigs are hard to find, expensive and delivery can be unpredictable. Block says it is open to making a new ASIC, which is the specialized gear used to mine for bitcoin.
The project is being incubated within Block’s hardware team, which is beginning to build out a core engineering team of system, ASIC and software designers led by Afshin Rezayee.
File this under “wishful thinking” if you want, but a fresh trademark filing for the Buick Electra name could mean that the storied nameplate is set for a return to US shores.
GM Authority reports that Buick parent company General Motors has renewed its trademark for the Buick Electra name in the US in a filing from 09DEC2025 with the United States Patent and Trademark Office (USPTO), and received an assigned serial number 99538079. The application carries a Goods and Services of, “Motor land vehicles, namely, automobiles.”
It’s worth noting, of course, that this most recent renewal for the Buick Electra trademark is a long, long way from a confirmation of a new all-electric Buick for the US market and even further from a confirmation that we’re getting the hot, sexy Electra GM sells in China. If anything, it’s likely just a matter of course legal thing that GM needs to protect its IP in China while, at the same time, preventing some kind of disastrous Sierra Mist scenario from playing out at home (which– yeah, I get that it’s not true, but you got the idea).
Combine that with an overwhelming desire to see a new-age Buick Grand National parked in my garage next Christmas and you can see that I’m not to be trusted. So, what say you? Head on down to the comments and let us know what you think of an American Electra revival just in time for the 2027 model year.

Heavy equipment giants Caterpillar have signed an agreement with Vale that will see the company dramatically expand its fleet of autonomous haul trucks deployed at iron ore operations in the Carajás region of Brazil over the next three years.
Vale’s Northern System mining operation currently has 14 CAT, 320-ton autonomous haul trucks in service. With this new deal, sold by Caterpillar’s Brazilian dealer, Sotreq, the autonomous haul truck fleet will expand to some ninety (!) of the massive, self-driving trucks by 2028. The big yellow trucks will be operated by CAT®, MineStar™ Command for hauling, and ship with a payload capacity of between 240 to an almost unimaginable 400 (!!) tons.
“We’re proud to introduce Cat Command for hauling at Vale’s Carajás site,” says Marc Cameron, Senior Vice President at Caterpillar. “By equipping Vale’s haul trucks with our autonomous technology, we will be delivering scalable solutions that meet their needs across a mixed fleet.”
CAT says this new deal represents, “a transformational leap,” citing the fact that autonomous trucks remove workers from hazardous areas and enable safer and more inclusive environments for mine employees – and more efficient operations for Vale.

That fact is backed by results from other Vale operations that have deployed large numbers of autonomous vehicles, which saw gains of up to 15% in operational performance and a 7.5% reduction in fuel use (more with electric drive), contributing to the reduction of the company’s carbon emissions. And, because this is end-stage capitalism 2025, they’re crediting AI for discovering those efficiencies.
“By integrating autonomous systems, artificial intelligence, and advanced data analysis, we are modernizing our mining operations in the Northern Corridor, becoming a global benchmark in smart mining, promoting the transformation of the industry, and connecting us to international best practices,” says Rafael Bittar, Vale Vice President, Technical.
The trucks will be delivered over the next three years, and are expected to be in full operation and up to speed by 2030.

As I’ve said before, EVs and mining to together like peanut butter and jelly. In confined spaces, the carbon emissions and ear-splitting noise made by conventional, ICE-powered mining equipment can create dangerous circumstances that can lead to serious injuries (or worse), and that’s just going to make it even harder for a mining operation to keep people working and minerals coming out of the ground.
By working with companies like Caterpillar to prove that forward-looking electric equipment can do the job as well as well as (if not better than) their internal combustion counterparts, Vale will go a long way towards converting what’s left of the ICE faithful.

Electric medium-duty startups Motive and Workhorse have logged millions of miles across their customer fleets — and by joining forces, they’re out to prove, once and for all, that electric vehicles can get the job done.
Following shareholder votes last month, Ohio-based Workhorse and San Francisco-based Motive are merging to form one of the largest commercial electric vehicle and last-mile delivery telematics solutions companies in the industry.
The all-stock transaction, announced last week, values the combined company at approximately $105 million and is expected to close in the fourth quarter of 2025, subject to Workhorse shareholder approval.
Under the terms of the agreement, Motiv’s controlling investor will become the majority owner with approximately 62.5% of the combined company, while Workhorse shareholders will maintain a significant equity stake of approximately 26.5%.
The move is intended to combine Workhorse’ manufacturing capabilities and nationwide dealer network with Motiv’s proven product portfolio and existing fleet relationships to serve the growing $23 billion medium-duty truck segment with a full range of Class 4-6 electric vehicles that plays to the strengths of both companies while, at the same time, proving them with economies of scale they’ll need to survive the next wave of fake “the EV market is dead” headlines.
“Bringing together two leading OEMs in the medium-duty space strengthens our ability to reduce the cost of electric trucks and make the total cost of ownership even more compelling,” said Scott Griffith, CEO of Motiv, who will lead the combined company. “We believe this is a coming-of-age moment — not just for Motiv and Workhorse, but for the industry as a whole.”

The companies anticipate a minimum of $20 million in cost synergies by the end of 2026 through reductions in redundant R&D, G&A, and facility costs (and, of course, the associated layoffs).
Workhorse’s Union City facility has the capacity to eventually produce up to 5,000 trucks per year — a significant manufacturing scale for the merged operation and light years ahead of what Motiv’s existing facilities can crank out.
“This transaction represents a significant milestone for Workhorse, our customers, our stakeholders and our shareholders,” Rick Dauch, CEO of Workhorse and advisor to the new, combined company told FreightWaves. “We believe Motiv is the right partner to support the advancement of our combined product roadmap and capture new growth opportunities.”
The new, combined electric box van company will being life with 10 of the largest medium-duty fleets in North America as existing customers, and hopes to expand their line of offerings into the electric bus and RV markets in the years to come.
Electrek’s Take

Workhorse and Motive can spin this merger however they like — but this move is as much about survival in the new, incentive-lite era of Trump 2 than it is about anything else. That doesn’t mean it’s not a smart move, as each of the parts of this new whole has eliminated a very strong competitor while, at the same time, gaining all at least some of their best features.
As cynical as I am about corporate consolidation and layoffs (especially during the holidays), I can’t help but think this could be a winning move.
