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.

UAW tells Stellantis workers to prepare for a fight, and vote for strike

The UAW union’s Stellantis Council met yesterday to discuss the beleaguered carmaker’s “ongoing failure” to honor the agreement that ended the 2023 labor strike, and their latest union memo doesn’t pull many punches.

It’s not a great time to be Stellantis. Its dealers are suing leadership and threatening to oust the company’s controversial CEO, Carlos Tavares, as sales continue to crater in North America, it can’t move its new, high-profile electric Fiat, and it’s first luxury electric Jeep isn’t ready. And now, things are about to get bad.

In an email sent out by the UAW earlier today (received at 4:55PM CST), UAW President Shawn Fain wrote, “For years, the company picked us off plant-by-plant and we lacked the will and the means to fight back. Today is different. Because we stood together and demanded the right to strike over job security—product commitment—we have the tools to fight back and win … We unanimously recommend to the membership that every UAW worker at Stellantis prepare for a fight, and we all get ready to vote YES to authorize a strike at Stellantis.”

The dispute seems to stem from Stellantis’ inability to commit to new product (and continued employment) at its UAW-run plants and other failings to meet its strike-ending obligations. This, despite a €3 billion stock buyback executed in late 2023.

I’ve included the memo, in its entirety, below. Take a look for yourself, and let us know what you think of the UAW’s call for action in the comments.

Kia EV9 GT caught with an active spoiler for the first time [Video]

Kia promises the new EV9 GT will have “enormous power,” but that’s not all. For the first time, the Kia EV9 GT was caught with an active spoiler, giving us a sneak peek at potential new upgrades.

The brand’s first three-row electric SUV is already making its presence known in the US, helping push Kia to back-to-back record sales months. Meanwhile, a more powerful, sporty variant is on the way.

Kia confirmed the EV9 GT will top off the electric SUV’s lineup in April. Packing “enormous power,” the high-performance GT model can accelerate from 0 to 62 mph (0 to 100 km/h) in 4 secs.

With a “high-output” dual-motor (AWD) system, the EV9 GT can quickly pick up speed despite weighing over 5,000 lbs.

Kia also equipped it with other high-performance features, such as a reinforced suspension and electronic braking system, for better control and stability.

We’ve already caught a glimpse of the performance electric SUV out testing, revealing aggressive new bumpers and wheels. Now, a new design feature has been spotted.

Kia EV9 GT could come with an active rear spoiler

The latest video from HealerTV shows the EV9 GT with what appears to be an active spoiler. As the reporter noted, it could be similar to the one spotted on the Genesis GV70 Magma.

Tesla’s Model X also used to come with an active spoiler until it was dropped a few years back. Although the GT model was spotted with one, Kia could just be testing new features, so don’t get too excited yet.

Earlier this week, a video from HealerTV showed the front row of the EV9 GT, comparing it to the current GT-Line model.

Several differences can be immediately noticed, including a more aggressive, all-black design with a yellow stripe down the center of the seat.

Kia is set to launch the EV9 GT in early 2025. It will rival other performance SUVs like the Tesla Model X Plaid.

Although prices have yet to be confirmed, the GT model is expected to sit above the current GT-Line at $73,900. In comparison, Tesla’s Model X Plaid starts at $94,990 and can sprint from 0 to 60 mph in 2.5 secs.

Chargeway and Consumer Reports team up to improve charging

Consumer Reports and EV charging app Chargeway are working together to give drivers a better way to rate public chargers, report uptime, and address maintenance issues.

The Chargeway app is best known for its use of numbers and colors to simplify the complexity of multiple charge ports and different charging speeds for new EV drivers. The app also enables Chargeway users to rate and review the public charging stations they visit – and now, those ratings can show up on Consumer Reports.

The technical collaboration with Chargeway is part of a larger effort called the EV Charging Community, which engages with a number of different EV advocacy groups including Plug In America, GreenLatinos, and Generation 180, and leverages the mobile app to rate public EV charging experiences based on various factors, with the findings reported back to industry stakeholders like EVSE manufacturers, CPOs, and utilities.

Be heard

“We are very excited to be partnering with Consumer Reports,” says Chargeway founder, Matt Teske. “From day one, Chargeway has focused on a driver first app design to provide easier EV charging experiences as well as transparency for what drivers can anticipate at (the) station they choose … we share Consumer Reports’ goal to give drivers a voice in the public EV charging reliability conversation. Now, instead of posting complaints on social media and feeling ignored, EV drivers can use the Chargeway mobile app to provide their feedback to the leading consumer advocacy organization.”

Consumer Reports says it’s already seen nearly a third of its 1,600 enrolled community members experience a problem with public charging, so it’s a real problem. “Charging stations are critical services, but when they’re out of order or barely functional, it wastes consumers’ valuable time,” explains Drew Toher, Consumer Reports’ sustainability campaign manager.

Consumer Reports points out that EV drivers who don’t use Chargeway can also enroll to be part of the community at this link.

Electrek’s Take

Chargeway founder Matt Teske is an old friend. He’s a good friend, too, so it’s great to see his top-shelf EV charging app starting to get some of the recognition it deserves. The CR tie-up and added visibility these ratings will give to industry stakeholders are only going to make things better for EV drivers everywhere.

That up there? That’s one of my early interview episodes of Quick Charge featuring a walkthrough of Chargeway+, another collab between Matt and Austin Energy. Enjoy!
