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.

EV with fake engine noises recalled for not having the correct fake engine noises

EV with fake engine noises recalled for not having the correct fake engine noises

The Dodge Charger Daytona EV made headlines when it rolled out fake engine noises as a way to make the EV appeal to muscle car drivers. As it turns out, they weren’t the right sort of fake engine noises – and now Stellantis has to recall 8,000 of them for a fix.

According to the ChryCo fans at Mopar Insider, Stellantis is recalling ~8,390 examples of its 2024 to 2025 Dodge Charger Daytona EVs because of an exterior amplifier that may be missing critical enabling the amp to emit exterior sounds – including the Federally mandated pedestrian warning sounds designed to keep pedestrians safe.

What’s more, the recall’s “suspect period” reportedly begins on 30APR2024, when the first 2024 Dodge Charger Daytona was produced, and ends 18MAR2025 … when the last Charger EV was produced.

RECALL CHRONOLOGY

  • On April 17, 2025, the FCA US LLC (“FCA US”) Technical Safety and Regulatory Compliance (“TSRC”) organization opened an investigation into certain 2024–2025 model year Dodge Charger vehicles that may not emit exterior sound.
  • From April 17, 2025, through May 13, 2025, FCA US TSRC met with FCA US Engineering and the supplier to understand all potential failure modes associated with the issue. They also reviewed warranty data, field records, and customer assistance records to determine field occurrences.
  • On May 14, 2025, the FCA US TSRC organization determined that a vehicle build issue existed on certain vehicles related to a lack of EV exterior sound, potentially resulting in noncompliance with FMVSS No. 141.

MOPAR INSIDER

Without the software patch, the vehicles don’t comply with the requirements of Federal Motor Vehicle Safety Standards (FMVSS) No. 141, “Minimum Sound Requirements for Hybrid and Electric Vehicles.” The rule requires noisemakers for EVs and hybrids when operating under 19 mph, the safest speeds for pedestrians.

Basically, if you have a Dodge Charger EV, expect to get a recall notice.

It just keeps getting funnier


My take on the Fratzonic Chambered Exhaust, via ChatGPT.

If you’re not familiar with the Charger Daytona EV’s “Fratzonic Chambered Exhaust,” it’s a system that employs a combination of digital sound synthesis and a physical tuning chamber (translation: a speaker) to produce a 126 decibel sound that approximately imitates a Hellcat Hemi V8 ICE. That’s loud enough to cause most people physical pain, according to Yale University – putting it somewhere between a loud rock concert and a passenger jet at takeoff.

While you could argue that such noises are part and parcel with powerful combustion, they’re completely irrelevant to an EV, and speak to a particular sort of infantile delusion of masculinity that I, frankly, have never been able to wrap my head around. Something akin to the, “Hey, look at me! I’m a big tough guy!” attention-whoring of a suburban Harley rider in a “Sons of Anarchy” novelty cut, without even enough courage to ride a motorcycle, you know?

You know – and I bet you can help me dial in the the comparison to perfection (and help me explain why the car just isn’t selling) in the comments section at the bottom of the page.

Kia's electric van spotted with an open bed and it actually looks like a real truck

Is it an electric van or a truck? The Kia PV5 might be in a class of its own. Kia’s electric van was recently spotted charging in public with an open bed, and it looks like a real truck.

Kia’s electric van morphs into a truck with an open bed

The PV5 is the first of a series of electric vans as part of Kia’s new Platform Beyond Vehicle business (PBV). Kia claims the PBVs are more than vans, they are “total mobility solutions,” equipped with Hyundai’s advanced software.

Based on the flexible new EV platform, E-GMP.S, Kia has several new variants in the pipeline, including camper vans, refrigerated trucks, luxury “Prime” models for passenger use, and an open bed model.

Kia launched the PV5 Passenger and Cargo in the UK earlier this year for business and personal use. We knew more were coming, but now we are getting a look at a new variant in public.

The folks at HealerTV found the PV5 variant with an open bed parked in Korea, offering us a good look from all angles.

From the front, it resembles the Passenger and Cargo variants, featuring slim vertical LED headlights. However, from the side, it’s an entirely different vehicle. The truck sits low to the ground, similar to the one captured driving earlier this month.

When you look at it from the back, you can’t even tell it’s the PV5. It looks like any other cargo truck with an open bed.

The PV5 open bed measures 5,000 mm in length, 1,900 mm in width, and 2,000 mm in height, with a wheelbase of 3,000 mm. Although Kia has yet to say how big the bed will be, the reporter mentions it doesn’t look that deep, but it’s wide enough to carry a good load.

The open bed will be one of several PV5 variants that Kia plans to launch in Europe and Korea later this year, alongside the Passenger, Cargo, and Chassis Cab configurations.

In Europe, the PV5 Passenger is available with two battery pack options: 51.5 kWh or 71.2 kWh, providing WLTP ranges of 179 miles and 249 miles, respectively. The Cargo variant is rated with a WLTP range of 181 miles or 247 miles.

Kia will reveal battery specs closer to launch for the open bed variant, but claims it “has the longest driving range among compact commercial EVs in its class.”

In 2027, Kia will launch the larger PV7, followed by an even bigger PV9 in 2029. There’s also a smaller PV1 in the works, which is expected to arrive sometime next year or in 2027.

What do you think of Kia’s electric van? Will it be a game changer? With plenty of variants on the way, it has a good chance. Let us know your thoughts in the comments below.

Solar and wind industry faces up to $7 billion tax hike under Trump’s big bill, trade group says

Solar and wind industry faces up to  billion tax hike under Trump's big bill, trade group says

Senate Republicans are threatening to hike taxes on clean energy projects and abruptly phase out credits that have supported the industry’s expansion in the latest version of President Donald Trump‘s big spending bill.

The measures, if enacted, would jeopardize hundreds of thousands of construction jobs, hurt the electric grid, and potentially raise electricity prices for consumers, trade groups warn.

The Senate GOP released a draft of the massive domestic spending bill over the weekend that imposes a new tax on renewable energy projects if they source components from foreign entities of concern, which basically means China. The bill also phases out the two most important tax credits for wind and solar power projects that enter service after 2027.

Republicans are racing to pass Trump’s domestic spending legislation by a self-imposed Friday deadline. The Senate is voting Monday on amendments to the latest version of the bill.

The tax on wind and solar projects surprised the renewable energy industry and feels punitive, said John Hensley, senior vice president for market analysis at the American Clean Power Association. It would increase the industry’s burden by an estimated $4 billion to $7 billion, he said.

“At the end of the day, it’s a new tax in a package that is designed to reduce the tax burden of companies across the American economy,” Hensley said. The tax hits any wind and solar project that enters service after 2027 and exceeds certain thresholds for how many components are sourced from China.

This combined with the abrupt elimination of the investment tax credit and electricity production tax credit after 2027 threatens to eliminate 300 gigawatts of wind and solar projects over the next 10 years, which is equivalent to about $450 billion worth of infrastructure investment, Hensley said.

“It is going to take a huge chunk of the development pipeline and either eliminate it completely or certainly push it down the road,” Hensley said. This will increase electricity prices for consumers and potentially strain the electric grid, he said.

The construction industry has warned that nearly 2 million jobs in the building trades are at risk if the energy tax credits are terminated and other measures in budget bill are implemented. Those credits have supported a boom in clean power installations and clean technology manufacturing.

“If enacted, this stands to be the biggest job-killing bill in the history of this country,” said Sean McGarvey, president of North America’s Building Trades Unions, in a statement. “Simply put, it is the equivalent of terminating more than 1,000 Keystone XL pipeline projects.”

The Senate legislation is moving toward a “worst case outcome for solar and wind,” Morgan Stanley analyst Andrew Percoco told clients in a Sunday note.

Shares of NextEra Energy, the largest renewable developer in the U.S., fell 2%. Solar stocks Array Technologies fell 8%, Enphase lost nearly 2% and Nextracker tumbled 5%.

Trump’s former advisor Elon Musk slammed the Senate legislation over the weekend.

“The latest Senate draft bill will destroy millions of jobs in America and cause immense strategic harm to our country,” The Tesla CEO posted on X. “Utterly insane and destructive. It gives handouts to industries of the past while severely damaging industries of the future.”
