Behind High Energy Consumption of Blockchain: PoS Consensus Mechanism To Be A Solution
The energy consumption of Blockchain
Recently, Elon Musk, the founder of Tesla, posted on Twitter saying that: Bitcoin can consume too much in mining and transaction process, such excessive fossil fuel consumption will result in negative impacts on the ecosystem. The Ethereum co-founder Vitalik Buterin also noticed the high power consumption problem in Blockchain technology. He presented that Ethereum would change its consensus mechanism from PoW to PoS to reduce the power consumption caused by the mining process in PoW-based technologies like the Bitcoin. From a global view, energy consumption issues are concerned by an increasing number of countries. To urge the efficient power usage, many countries and organizations have set up environmental protection plans, such as the UN’s SDG (Sustainable Development Goals) and the US carbon neutrality, etc.
In this context, the future development of a technology need to consider the sustainable development and environmental friendliness as one of the important metrics and goals. As an emerging technology for privacy protection, Blockchain presents excellent protection capabilities. However, such capabilities rely on the large-scale computing resources and result in a large amount of power consumption. Part of the reasons for such high power consumption are due to the PoW (Proof of Work) consensus mechanism which has high demands on the performance of the Blockchain nodes.
Besides energy consumption, other concerns of the consensus mechanism
The technology of the base layer of the Blockchain has the advantages like anonymous, Immutable, decentralized and so on. To achieve these advantages, Blockchain enhances the privacy and protect the transaction process by increasing the cost of network participation. The core concept of the early-stage PoW consensus mechanism is based on the workload cost. The credibility need to be proved by the cost of a lot of work. In this case, the machines that maintain the ledgers (also referred to as mining nodes) need to continually crack complex math puzzles to obtain Bitcoin as rewards. This computing process not only needs to rely on a large amount of computing resources, but also sacrifices part of the scalability on the Blockchain to ensure safety. When it comes to the boosting growing of transaction volume, this mechanism will not be able to meet high-speed and large-scale processing demands. Based on such limitations of PoW, PoS (Proof of stake) is gaining more and more attention to work as a consensus mechanism with low resource consumption and guaranteed decentralization, safety and scalability.
In a PoS-based Blockchain system, nodes do not have to consume much power to compete for accounting rights. The priority of accounting rights is measured by the amount of stake holdings. In this way, the nodes no longer consume a large amount of electricity to calculate the hash functions, thereby solving the high energy consumption issues in PoW mechanism. In spite of the improved efficiency in PoS, the safety of the mechanism is affected. Therefore, in order to ensure the reliable operation of PoS, the researchers need to develop reliable algorithms from the trade-off among the decentralization, safety and scalability.
Unique advantages of PlatON PoS
With the issues caused by the PoW mechanism has been widely criticized, more and more Blockchain technologies inclined to choose or transit to the PoS-based consensus mechanisms. This results in a boosting growing of the PoS-based Blockchain frameworks in recent years. As the world leader in computing privacy area, PlatON has rooted and researched in privacy computing technologies many years. PlatON’s research and practice in consensus mechanisms are also forward-looking. The PPoS (PlatON PoS) consensus mechanism uses off-chain identity, credit mechanisms and procedural arrangements to provide a scheme to select a number of verification nodes from many participating nodes as fair and randomly as possible. Hence, PPoS can effectively inhibit bribery, collusion, etc., and reduce the consensus cost and improve the system scalability by optimizing technical details. Meanwhile, ensuring the decentralization and scalability, PlatON further enhances the system safety by combining the experiences in computing privacy area. The Alaya network based on PlatON PoS has been operating stably and efficiently for a long time, successfully solving the problem of over-centralization of the system, reducing network communication complexity and message complexity, improving consensus efficiency and the entire Blockchain transaction processing performance. In this case, the safety and liveness of the technology are verified. PlatON has been able to improve its PoS mechanism through its attention to every detail, continuous attempts, active exploration of cutting-edge areas, and forward-looking plans in the future development. Next step, PlatON will continue actively promoting the efficient network operation with high-quality code, providing efficient, high-availability, distributed and sustainable infrastructure applicable for diverse industrial and commercial use cases, and supporting the exchange of data flows in the global world.

Karunamaya Vesna Blazhevska sets a personal challenge: seven days of small climate action
New York City, NY, 4th September 2026, ZEX PR WIRE, Karunamaya Vesna Blazhevska has worked within United Nations Sustainable Development communications since 2008. Her work involves helping large, complicated ideas about the environment and international cooperation reach ordinary readers. She has decided to turn some of that thinking into a short, practical challenge that anyone can try, using seven days as the frame.
The idea is simple. Each day points to one Sustainable Development Goal and one small action tied to it. Nothing on the list requires special equipment or money. Blazhevska says she designed it that way on purpose.
“Big goals get people excited for a week and then they quit,” she says. “I wanted something a person could actually keep doing after the challenge ends.”
The seven-day plan
Day 1, climate action. Skip one car or rideshare trip. Walk, bike, or take transit instead.
Day 2, affordable and clean energy. Unplug devices that sit idle overnight. Blazhevska points out that standby power adds up over a year, even if it feels small on any single day.
Day 3, quality education. Spend twenty minutes reading about one environmental topic you do not already understand well. She suggests picking something specific, like ocean plastic or soil health, rather than a broad subject.
Day 4, gender equality. Support or promote the work of a woman colleague or a woman-led project you respect. Blazhevska frames this as a habit of attention, not a one-time gesture.
Day 5, responsible consumption. Try one full meatless day. This is the piece of the challenge closest to her own life. She has been vegetarian since 1991, avoiding meat and fish while still eating cheese, eggs, and yogurt. “I’m not asking anyone to do what I do for thirty-five years,” she says. “I’m asking for one day, to see how it feels.”
Day 6, life below water. Cut back on single-use plastic for the day. Bring a reusable bottle or bag instead of a new one.
Day 7, peace. Have one respectful conversation with someone whose views differ from yours, without trying to change their mind. Blazhevska sees this as connected to her interest in harmony among different faiths and backgrounds. “Peace starts in small exchanges before it shows up anywhere bigger,” she says.
Why she built it around small steps
Blazhevska says her communications work has taught her that people respond to specifics, not slogans. A goal like “protect the climate” is hard to act on directly. Turning off a device or skipping a car trip is not.
She also says the challenge reflects something she has learned from her own long-standing habits. Her vegetarian diet has lasted more than three decades not because she set out to prove something, but because it became ordinary. She hopes the same happens with small climate habits: that they stop feeling like a challenge and become routine.
“None of these seven days ask for something dramatic,” she says. “They ask for something repeatable.”
How to take part
Blazhevska is encouraging people to pick any single day from the list and try it this week, rather than waiting to start all seven at once. She says starting small and staying consistent matters more than doing everything at once.
She also notes the challenge is meant to be shared informally, among coworkers, friends, or community groups, rather than tracked through any formal program. “The point isn’t a certificate,” she says. “The point is that seven habits are easier to keep than one big promise.”

Ned Curic Highlights Customer-First Approach to Technology and Product Development
Stellantis technology executive emphasizes practical innovation, integrated engineering and the importance of building technology around real customer needs.
Illinois, CA, 4th September 2026, ZEX PR WIRE, As artificial intelligence, advanced computing and connected technologies become increasingly important to product development, Ned Curic believes the value of innovation should still be measured by a straightforward standard: whether it makes the product better for the person using it.
Curic, who is responsible for Product Development & Technology at Stellantis and is a member of the Stellantis Leadership Team, has spent his career working across engineering, software and automotive technology.
His approach places the customer at the center of technology decisions rather than treating new technology as an objective on its own.
“Technology only matters if it makes life better for people,” Curic has said.
The principle has become increasingly relevant as companies gain access to more powerful artificial intelligence, computing systems and development tools. The challenge is no longer simply whether a technology can be built or incorporated into a product. Companies must determine where it creates meaningful improvements for customers.
Building Technology Around the Product
For the automotive industry, that distinction is especially important.
Modern vehicles bring together mechanical engineering, electronics, computing, software, design, manufacturing and increasingly sophisticated artificial intelligence. Customers, however, experience those individual technologies as one product.
Curic has publicly emphasized the importance of viewing the vehicle as a complete system rather than allowing any individual technology to become the product’s defining purpose.
That philosophy also influences how Stellantis approaches product development.
In February 2025, Stellantis integrated its software activities into the Product Development & Technology organization led by Curic. The company said the change was intended to streamline the process of bringing products and services to market across its brands and markets.
The organizational structure brings technologies that increasingly influence the customer experience closer to the broader engineering and product-development process.
Rather than separating software from the rest of vehicle development, the approach reflects the reality that customers ultimately judge how all parts of a vehicle work together.
From Technical Capability to Customer Value
The rapid development of artificial intelligence provides another example of the distinction between technical capability and practical value.
Stellantis has been exploring AI across areas including engineering, manufacturing, vehicle technology and customer interaction.
Curic has consistently framed those efforts around tangible results.
When Stellantis expanded its collaboration with Mistral AI in 2025, Curic said the companies were exploring applications of artificial intelligence that could enhance product development and the customer experience while delivering real benefits.
That focus places a higher standard on innovation than novelty alone.
A new technology may be technically impressive, but its long-term value depends on whether it can improve quality, simplify an experience, accelerate development, increase capability or address another genuine customer or business need.
The same principle applies as AI becomes a larger part of engineering and product-development workflows.
Technology can help teams analyze information, test ideas, improve development processes and create new experiences. The objective, however, remains the product rather than the technology used to create it.
Innovation Requires Integration
Curic’s perspective has been shaped by a career spanning several technology-intensive industries.
He began his career in Engineering Systems at Northrop Grumman in 1996 before joining Microsoft in 2000, where he held positions in consulting, product, security and advisory functions.
He entered the automotive industry in 2013 as Group Vice President and Chief Technology Officer at Toyota Motor North America. In 2015, he became a co-founder of Toyota Connected, serving as Executive Vice President, Technical Director and Board Member.
Curic joined Amazon in 2017 as Vice President of Alexa Automotive, spearheading the company’s efforts in the automotive industry.
In August 2021, he joined Stellantis as Chief Technology Officer. His responsibilities later expanded to encompass engineering and research and development before Stellantis brought software activities into the Product Development & Technology organization in 2025.
Across those roles, Curic has worked in environments where multiple technologies, teams and disciplines must contribute to a single product or customer experience.
That experience underpins an approach to innovation based on integration rather than technology in isolation.
A Practical Standard for Emerging Technology
The number of technologies available to product-development organizations will continue to grow.
Artificial intelligence is advancing rapidly. Computing capability continues to increase. Development tools are becoming more sophisticated, and vehicles are incorporating increasingly complex electronics and connected functions.
For Curic, those developments do not change the fundamental purpose of technology.
The relevant questions remain practical ones: Does it improve the product? Does it make something easier for the customer? Does it solve a genuine problem? Does it enable an experience that people actually value?
Those questions can also help organizations distinguish lasting innovation from short-term technology trends.
The companies best positioned to benefit from emerging technologies may therefore be those that are most selective about how they use them—integrating technology where it improves the complete product rather than adding capability simply because it is available.
As the automotive industry continues to evolve, Curic’s approach keeps the emphasis on an outcome that is easy to understand even when the technology behind it is increasingly complex: building better products for the people who use them.
