Mina Protocol Completes Major Upgrade Bringing Enhanced ZK Programmability to Mainnet

Published

on

The upgrade establishes Mina as the first zero knowledge (ZK) blockchain with native ZK programmability, enabling developers to build with a powerful framework for leveraging ZK features for scalability, privacy, and verification in their applications

GENEVA, June 7, 2024 /PRNewswire/ — Mina Protocol, the zero knowledge (ZK) blockchain for proving anything, has completed a major network upgrade process bringing enhanced ZK programmability to its mainnet. The upgrade enables zkApps to be built and deployed on the Mina mainnet, setting the stage for the development of new zero knowledge-powered use cases and equipping builders with a powerful and easy-to-use ZK developer toolkit.

In development since 2021, the long-anticipated upgrade moves smart contract execution off-chain, and leaves verification on-chain, solving many of the most common blockchain infrastructure challenges, such as data constraints, scalability issues, and high gas costs. This paradigm shift makes it easier for developers to build with zero knowledge and create zkApps, granting new levels of control and ownership for users over their data.

zkApps can enable and scale new use cases for voting, healthcare, digital identity, gaming, and much more. Examples of projects already building in the Mina ecosystem include PunkPoll, a censorship-resistant survey and voting platform, bioSNARKs, a stack for biotech data, Hakata, a solution offering “compliant privacy” for Web2 and Web3 companies, and Paima Studios, an engine for on-chain gaming. Unlike many other dApp platforms that use new programming languages, zkApps use o1js, a TypeScript-based library already understood by a wide pool of TypeScript developers who are now empowered to build with ZK.

Kurt Hemecker, CEO of Mina Foundation, an organization serving the Mina Protocol and its ecosystem, said, “This upgrade not only marks a major milestone for the Mina community but is a significant breakthrough for the industry as a whole. The killer use cases for blockchain – DeFi, on-chain gaming, digital identity, blockchain interoperability, voting, secure supply chains, and compliance – all require zero knowledge proofs as a foundation to innovate and scale. Unlocking ZK programmability will give developers the building blocks to plug and play with ZK. By enabling the creation of more powerful applications built on top of Mina’s optimized proof layer, this upgrade pushes us closer to a truly verifiable, trustless internet.”

Designed to be the most succinct blockchain that gets more decentralized as it scales, Mina’s entire state history is represented by a recursive zero knowledge proof (ZKP), making it accessible and verifiable by anyone from any device. This single ‘proof of everything’ acts as an open database of true statements, where developers have access to all previous computation to extend or reuse, setting a strong foundation for tomorrow’s innovators to build the ‘Internet of (True) Things.’

Brandon Kase, CEO of o1Labs, the software development company that incubated Mina Protocol, elaborated, “The real magic happens when you look beyond just privacy or scalability. Attesting to individual statements of facts is useful within specific applications, but the true potential of Mina will be realized by those who harness the power of massive collaborative computation. Mina is on the precipice of opening up a vast new design space, and today, we take another step forward together with the community. This upgrade would not have been possible without the active participation of 400+ node operators, who played a key role in ensuring the smooth transition of the network, and hundreds of developers in the community who have been experimenting and sharing valuable feedback with early versions of o1js and other Mina platform tooling.”

In HelloNation, Electrical Expert Sean McGahy Breaks Down How a Whole Home Surge Protector Works

Published

The Article Explains How This Type of System Protects a Home’s Electronics From Power Surges Throughout the Day.

WAKE FOREST, N.C., Oct. 26, 2026 /PRNewswire/ — What does a whole home surge protector do? A HelloNation article answers that question and explains how this type of device defends a home’s wiring and electronics from voltage spikes.

The article explains that many power surges happen quietly throughout the day, often without anyone noticing. Large appliances such as air conditioners and refrigerators create small voltage spikes every time they cycle on and off.

According to the article, a whole home surge protector is installed directly at the electrical panel, where it can monitor voltage across the entire house. Unlike a power strip, which protects a single outlet, this device works at the source.

The article notes that modern homes rely on sensitive electronics, including smart thermostats, entertainment systems, and connected appliances. Repeated voltage fluctuations can damage this circuitry over time, even when a homeowner never notices it happening.

External surges from lightning strikes or utility grid fluctuations tend to be more severe than everyday cycling surges, the article explains. A whole home system is designed to respond quickly and redirect excess voltage away from a home’s circuits.

Installation is typically straightforward for a licensed electrician and does not usually require major changes to existing wiring, the article states. Many systems include indicators that let homeowners confirm the device is functioning properly.

The article points out that surge protectors are rated by how much energy they can absorb, often measured in joules. Homes with more electronics generally benefit from a protector with a higher rating.

A protector does not last forever, the article notes. Absorbing a large surge can wear down its internal components, even if the device still looks functional. Periodic testing by an electrician can confirm the system is still working as intended.

Electrical Expert Sean McGahy of Zar Electric is featured in the article. The article explains how periodic testing can confirm that a whole home surge protector is still providing the level of protection it was designed for.

The article adds that surge protection works best as one part of a broader approach to electrical safety. Homes should still have properly functioning breakers, updated wiring, and routine inspections alongside this added layer of defense.

Homes in areas prone to storms or frequent power fluctuations may see added value from this protection, the article notes. New construction offers a convenient time to add it, though retrofitting an existing home is described as achievable and usually quick.

The article notes that cost varies depending on the type of system installed and the complexity of a home’s existing electrical setup. Many homeowners view the expense as reasonable compared to the potential cost of replacing damaged electronics after a serious surge event.

Some insurance providers take note of these systems when evaluating a home’s overall risk profile, the article adds, though policies vary from carrier to carrier. This is described as one more reason homeowners weigh the value of this type of protection.

The article closes by noting that deciding whether this protection makes sense often comes down to a home’s electronics, its location, and a homeowner’s comfort level with risk. A licensed electrician can walk through these considerations before a final decision is made.

In HelloNation, Building Materials Expert Andy Maetzold Explains How Freeze-Thaw Cycles Affect Minnesota Homes

Published

By

The Article Shows How Moisture, Temperature Swings, and Hail Shape Material Choices for Roofs, Windows, Walls, and Decks.

WACONIA, Minn., Oct. 26, 2026 /PRNewswire/ — How do freeze-thaw cycles damage a home in Minnesota? The answer appears in a HelloNation article that was newly published for homeowners choosing building materials for a cold climate. The article features insights from Building Materials Expert Andy Maetzold, a fourth-generation member of the family behind Mayer Lumber.

The HelloNation article explains that a Minnesota home faces a wider range of weather than houses in most of the country. Below-zero nights, humid summers, and hailstorms all test the products used to build and repair it.

According to the article, moisture often does more harm than cold by itself. Water seeps into small gaps, freezes overnight, and expands, and repeated freeze-thaw cycles slowly push joints and seams apart.

The article also notes that large temperature swings make many products expand in summer and shrink in deep cold. Materials installed without room to move can buckle, crack, or pull loose from their fasteners.

The roof takes more of this stress than any other part of the house, the article explains. Asphalt shingles remain the most common choice because they are affordable and familiar to most roofing crews. In areas that see hail, many homeowners look at impact-resistant shingles that earn a Class 4 rating.

The article points out that some insurance companies offer lower premiums for Class 4 roofs, though discount rules vary by insurer. Metal roofing is another option that sheds snow quickly, and snow guards are often added above doors and walkways.

Ice dams get special attention in the piece. The article explains that no shingle stops them alone, because the real cause is warm air leaking into the attic and melting snow on the upper roof. Air sealing, attic insulation, and steady ventilation deal with that heat directly.

Cold-climate building codes also call for an ice barrier membrane under the shingles along the eaves, according to the article. This layer helps keep backed-up water away from the roof deck and the ceilings below.

For windows, the article points readers to the National Fenestration Rating Council label and its U-factor, which measures how easily heat passes through the whole unit. A lower number means better insulation and a warmer glass surface on a January night.

The article compares double-pane windows with triple-pane units, which cut heat loss further but cost and weigh more. It also notes that vinyl and fiberglass frames insulate well, while aluminum frames need a thermal break to suit Minnesota winters.

Walls, decks, and lumber are covered as well. The article explains that house wrap and flashing protect wall framing from water, and that wood touching concrete or soil generally needs pressure treatment.

The insights from Building Materials Expert Andy Maetzold also address cost. The article encourages comparing the full life of a product rather than the purchase price alone, since a cheaper material that needs frequent repairs can cost more over 20 or 30 years.

Finally, the article advises checking with local building officials about code rules. It also stresses following manufacturer installation instructions, since many warranties depend on them.
