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.

Mary Kay goes electric with new Pink Cadillac OPTIQ (cue the music)

Mark Kay’s iconic Pink Cadillac awards are driving into the future for 2025. The company’s first-ever electric Pink Cadillac OPTIQ made its debut during the Mary Kay annual Seminar in Charlotte this weekend, symbolizing a “recharged vision” for the future of the popular brand.

Pioneers in monetizing friendships female empowerment and entrepreneurship, the Pink Cadillac is considered one the most coveted symbols of achievement for Mary Kay sales reps, signifying not just great sales (GM Authority reported that it took ~$102,000 in annual sales to qualify back in 2001), but also leadership, a history of mentoring others, and a sustained reputation of excellence among their peers.

The women you see behind the wheel of the Pink Cadillac are the real deal, in other words, and the big Caddy really does mean something to people in the know.

The iconic pink Cadillac was born in 1968 when Mary Kay Ash purchased a Cadillac Coupe De Ville from a Dallas dealership and promptly had it painted to match the pale pink Mary Kay lip and eye palette. General Motors later named the color Mary Kay Pink Pearl, and the shade is exclusive to Mary Kay.

MARY KAY

Now, the Pink Cadillac is going to stand for environmental sustainability, too, enabling Mary Kay’s top performers to set yet another positive example for anyone aspiring to their success.

“For decades, the Mary Kay pink Cadillac has symbolized accomplishment, aspiration, and the power of recognition,” said Ryan Rogers, Chief Executive Officer of Mary Kay. “With the introduction of the all-electric OPTIQ, we’re honoring that iconic legacy while driving into a transformative future—one grounded in our commitment to sustainability and dedication to inspiring and celebrating the achievements of our independent sales force for generations to come.”

Mary Kay announced its new Pink Cadillac with this video, below.

Same Legacy, New Energy


“The legacy continues with the new, all-electric (and still very pink) Cadillac Otiq [sic],” reads the official Mary Kay copy on YouTube. “The Optiq remains instantly recognizable with the pink pearl exterior, while modernizing with sleek, cutting-edge features. In addition, this vehicle showcases our commitment and dedication to sustainability by reducing our carbon footprint while continuing to inspire.”

Speaking of inspiration, I can’t hardly hear the words “Pink Cadillac” without thinking of the song. But, since “Bruce Springsteen” has become something of a trigger word for the MAGA snowflakes in the audience, I’ll post a different, but similarly great song about rose-tinted GM flagships from Dope Lemon. You can let me know what you think of it in the comments.

As ever, the Cadillac is not a “gift,” per se – but typically takes the form of a two year lease paid for by Mary Kay. No word yet on what the exact shape and form the OPTIQ deal will take.

Electrek’s Take


Whatever you might think of MLMs or businesses like Amway, Avon, or Mary Kay, they play a big part in the social dramas of hundreds (if not thousands) of neighborhoods and online communities. The people at the top are influential, and the people “below” them genuinely try to emulate them and follow their lead.

Thanks to Mary Kay, that might soon mean a decision to buy an electric vehicle – and that result would be a win for everyone.

First drive – RBW’s electric Roadster is a sporty modern take on British classics

First drive - RBW's electric Roadster is a sporty modern take on British classics

RBW, a British handcrafted electric car manufacturer, brought its cute little Roadster out to Santa Monica and invited us up for a drive.

RBW has built cars in the UK for a few years now, but is about to set up US manufacturing in Virginia. Along with that comes a version of its Roadster modified for the US market, and we got a sneak peek with a short drive in Santa Monica.

The RBW Roadster is a small, hand-built, retro-style EV, meant as a modern take on British classics. But it’s not an actual classic itself – it’s a newly-built vehicle, with a new body, modern safety features, and even some electronics, like CarPlay and Android Auto (but not much else – there’s no huge, cockpit-defining screen, just a 9″ one, with retro gauges in front of the driver. But it does have a backup camera!).

Our drive was short, just a quick trip up and down the most trafficky part of Pacific Coast Highway in Santa Monica, without much chance to really stretch the vehicle’s legs. So we can’t verify range or tell you how it handles on the limits, but we can tell you about the basic controls and feel of the vehicle.

On a mostly smooth road, the car offered a comfortable ride dynamic. We didn’t get a sense of chassis noise because the top was down (which I surmised was an intentional effort by the company – I’ve used the same trick when showing off my car before).

The steering is tight and has a good weight to it, and the retro-style steering wheel felt great in my hands.

Of particular interest to me, as a long-time EV driver, is how the throttle pedal is tuned. Lots of EVs add some intentional delay or smoothing to throttle inputs, which ends up making the pedal feel mushy and indirect, reducing the control you have over the vehicle.

For reference, the cars I drive most often are the Tesla Roadster and Model 3, which both have excellent direct pedal feel.

And I’m happy to report that the RBW Roadster’s throttle pedal feels very similar to the cars I love to drive. The car feels quick, and responds exactly to what I want it to do, when I want it to do it. But it’s not excessively “punchy” like some of the more absurdly-powered EVs can be (like the Tesla Model S Plaid or the Macan Turbo S).

It does not, however, have off-throttle regenerative braking, aka one-pedal driving. Pressing the brake pedal engages regen, but letting off the throttle lets you simply coast. I personally prefer one-pedal driving, but one consideration RBW had is that since the car does not have traction control, regenerative braking on the rear axle (where the motor is) could potentially present a safety issue on slippery roads. So, fair enough I guess, but I still do prefer one pedal.

Speaking of pedals, the brake pedal was placed quite far from the accelerator. This is a plus and a minus – a minus because it’s quite different from most vehicles these days, where the pedals are placed closer, for ease of reaching them with your right foot. A plus because higher separation might reduce the chance of “crossing the pedals” and accidentally pressing both with the same foot in an emergency situation, and because it enables left-foot braking, which is generally better for performance driving… in the hands of a trained driver, anyway.

That said, this isn’t exactly a performance car. It’s fun, it’s responsive, but it’s not powerful. The version we tested had a 0-60 time of only around 9 seconds, so it didn’t give you the “throw your head back” feeling that so many EVs on the road these days do. It’s responsive, but not fast.

RBW says the American version will have more motor power than the UK version, but it’s still trying to figure out exactly how to tune it. This should bring 0-60 times down by about a second. But we can’t help but think that it would be nice with even a little more power than that, which we think should be possible given the car’s 50kWh battery and ~2,900lb weight, specs that are similar to my similarly-sized Tesla Roadster (as you can see below – along with the GT version of the RBW, on the right).

Here’s an issue: all the specs we were given seem extremely fluid. While talking to the company, I got several different numbers for any given specification. It seems to me like the company is still figuring out exactly what changes it will make for its US models.

This is somewhat to be expected of a small, hand-built manufacturer, especially since buyers can ask for certain modifications or personalizations (seat height, for example, which is important in a small car like this). But it does make it tough to write an article about it.

Nevertheless, the car drives well, and RBW seems to have gotten a lot right about the dynamics of the vehicle. It executes well on its goal – a fun, small British-style roadster, a great weekend car for those who have the means.

As for the means, the RBW Roadster will start in the $140-150k range, so it’s not cheap. But if you’re looking for something like this, it’s just about the only game in town, and it’s a good execution of the feel of a nimble roadster for weekend cruising.

RBW is currently taking $1,000 reservations for 2026 builds, and you can have a look at configurations (paint, roof, interior, wheels) over on its website.

This cool-looking electric motorcycle wants to pretend to be an e-bike

This cool-looking electric motorcycle wants to pretend to be an e-bike

Canadian startup Beachman has just unveiled its latest electric two-wheeler, the ’64, a vintage-styled electric motorcycle that looks like it rolled straight out of the 1960s. With throwback café racer design and a respectable top speed of 45 mph (72 km/h), it’s a slick little ride with a curious twist: it calls itself an e-bike.

It’s not just a casual reference, but it’s baked into the name. The full model name on Beachman’s website is the ’64 E-Bike.

While I’d generally be inclined to give them the benefit of the doubt, since many motorcyclists refer to electric motorcycles as “e-bikes” and the term has a broad definition in colloquial usage, the company is obviously casting more in the “electric bicycle” end of the spectrum. They even say on their website that it is “rideable as either a Class II E-Bike or a Registered Moped (in most states).”

Despite lacking pedals entirely – and clearly designed more like a lightweight electric motorcycle – the Beachman ’64 comes with a selectable “E-Bike Mode” that limits it to 20 mph (32 km/h). The implication? That riders can use this obvious motorcycle in bike lanes like a Class 2 e-bike. Legally speaking, that’s a stretch, to put it mildly. In fact, I’m not currently aware of any state where that’s explicitly legal, though it could probably pass in many states due to the current state of enforcement we usually see.

According to Beachman, the ’64 has three ride modes:

  • E-Bike Mode: 20 mph (32 km/h) top speed, which the company says is “perfect for bike lanes.”
  • Moped Mode: 30 mph (48 km/h) top speed, which does match legal definitions for mopeds in some jurisdictions, even without pedals.
  • Off-Road Mode: 45 mph (72 km/h) top speed, no pretense – just a motorcycle.

In practice, I don’t think it’s a stretch of the imagination to assume that most riders will likely keep it in Off-Road Mode, where the bike delivers its full 3,000W performance and offers the most fun. And specced with decently large batteries, it could actually do some modest commuting, even at higher speeds. The ’64 comes with a removable 2.88 kWh battery (or optional 3.6 kWh upgrade), and range is estimated at 55–70 miles, depending on configuration. It charges to 80% in three hours and even features regenerative braking.

The company leans heavily on its “timeless design” messaging, and to their credit, the ’64 nails the aesthetic. It looks great. The frame, tank, and seat all channel classic motorcycle vibes while skipping the modern digital overload – no apps or touchscreens here. Just a clean, simple throttle and some retro charm.

But for all the cool factor, the classification confusion raises eyebrows. Calling a 45 mph, pedal-less motorcycle an “e-bike” in any meaningful legal sense is a misfire. Some states allow low-speed mopeds in bike lanes, but others draw the line at motorized vehicles without pedals. The ’64 might get away with it in limited cases, but most jurisdictions will (rightfully) require it to be registered and insured as a motor vehicle. And it’s unclear if explaining to the officer, “But I had it in 20 mph mode…” will help much on the side of the road.

Still, Beachman is aiming at a particular rider who wants motorcycle style and speed without all the baggage. With a starting price of $4,800, the ’64 could be an appealing step-up for e-bike riders looking to graduate into something faster without committing to a full-sized gas bike.

Just don’t expect to blend in on the bike path.

Electrek’s Take

Look: The bike looks fantastic and probably rides well, but come on, it’s a 230 lb (105 kg) motorcycle.

Let’s stop calling every throttle-only EV an e-bike just because it’s got two wheels, a battery, and a button that neuters it to 20 mph. This has gotten silly. You built a great-looking bike. But it’s a bike in the way a motorcycle rider refers to his “bike.” It’s not a bicycle, and it’s not a bike lane vehicle any more than a Sur Ron is. At least not if you respect your fellow two-wheel riders around you.
