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.

Gary Bassett Shares Lessons From 45 Years Across Finance and Technology
The Dallas-based finance and technology entrepreneur discusses how experience in investment banking, community banking, software, acquisitions, and asset management has shaped the questions he asks when evaluating new opportunities.
DALLAS, Texas, 26th September 2026, ZEX PR WIRE— A promising business opportunity can look very different depending on which side of the table someone is sitting on.

After more than four decades working across finance and technology, Gary Bassett has occupied several of those seats. He has analyzed companies as an investment banker, worked inside community banking, built and operated an enterprise software company, experienced an acquisition as a founder, and later returned to institutional finance.
Each experience, Bassett says, added another question to the way he evaluates an opportunity.
“Early in my career, I learned to ask whether the numbers supported the story,” Bassett said. “Later, after running a company myself, I learned to ask another question: What actually has to happen every day for those numbers to become real?”
Looking Beyond the Initial Opportunity
Bassett began his career in investment banking at J.P. Morgan in New York in 1979. His work included financial modeling, valuation, due diligence, and corporate debt transactions.
The experience taught him to examine the assumptions underneath a proposal rather than focusing only on its potential.
“An idea can sound very compelling until you start changing the assumptions behind it,” Bassett said. “What happens if growth is slower? What happens if the cost is higher? What has to go right for the plan to work? Those were useful questions to learn early.”
His subsequent experience in Texas banking brought those questions closer to individual businesses and communities.
Bassett became a founding shareholder of Lamar National Bank and served as president of the Lamar Bank Center. The work exposed him to commercial banking, lending, real estate, and the practical consequences of financial decisions.
That perspective became particularly important when Bassett moved from analyzing businesses to building one.
Building Microbank Changed the View From the Other Side
In 1985, Bassett founded Microbank Software Inc., an enterprise software company serving organizations in banking and construction.
Running the company introduced a different set of considerations. A business could not succeed on strategy alone. Products had to work. Customers had to see value in them. Employees had to execute. Problems that appeared small on paper could become much larger when they affected day-to-day operations.
“Building Microbank changed the way I looked at companies,” Bassett said. “When you have been responsible for the product, the customers, and the decisions that have to be made on Monday morning, you start asking different questions when you look at a business.”
Microbank eventually developed an international client base and was acquired by Citicorp. Bassett also participated in the integration that followed the acquisition.
That process added another layer to his experience. Evaluating whether two businesses make sense together is one challenge. Integrating people, systems, customers, and operating processes after a transaction is another.
“A transaction has a closing date, but the work of combining organizations does not end on that date,” Bassett said. “That experience made me pay much more attention to what has to happen after an agreement is signed.”
Returning to Investment Banking With an Operator’s Perspective
Bassett later spent nearly a decade as a managing director at Bank of America, working in investment banking, mergers and acquisitions, capital markets, and strategic advisory assignments.
He returned to institutional finance with experience he did not have earlier in his career: he had founded and operated a company himself.
Bassett says that experience made him more interested in what sits behind financial statements and projections.
“Numbers are important, but every number came from something that happened inside the business,” he said. “There are customers, employees, operating decisions, competitors, and unexpected problems behind those results. I became much more interested in understanding that part of the story.”
Experience Can Change the Questions
Today, Bassett is the founder, chairman, and managing partner of Dallas-based HP Capital Partners, which he established in 2012.
His career has crossed industries and roles, but Bassett does not view those experiences as separate chapters with no connection to one another.
Instead, each has influenced how he approaches the next opportunity.
For business leaders, he believes evaluating an opportunity requires more than asking how attractive the potential outcome appears. It also means examining assumptions, understanding how an organization actually operates, considering what could disrupt the plan, and determining whether the people and systems involved can execute it.
“Experience does not mean you automatically know the answer,” Bassett said. “If anything, it gives you more questions to ask. I think that is useful. The goal is not to make every opportunity look good or bad. It is to understand what would actually have to happen for it to work.”

Nivia Fontanez Highlights the Often-Overlooked Role of Radiology Technologists in Patient Care
Bronx-based radiology technologist Nivia Fontanez discusses the communication, preparation, positioning, safety, and attention to detail behind medical imaging.
BRONX, N.Y, 26th September 2026, ZEX PR WIRE, When patients arrive for an X-ray or CT scan, much of their attention naturally goes to the imaging equipment. Behind the technology, however, is a radiology technologist who guides the patient through the process and performs the study according to established procedures.
Bronx-based radiology technologist Nivia Fontanez believes patients may not always see the human side of the profession.
Fontanez works with X-rays, CT scans, and bone density studies. She holds a New York State radiologic technologist license and is qualified to administer contrast for CT studies. Her experience has shown her that medical imaging requires technical knowledge, but operating equipment is only one part of the technologist’s responsibilities.
“Patients see the machine because that is the most obvious part of the room, but there is a lot happening around it,” Fontanez said. “We are thinking about positioning, instructions, safety, and whether the patient understands what we need them to do.”
Positioning Requires Working With the Individual Patient
Positioning is one example of a responsibility that can appear simple from the patient’s perspective. A technologist may ask someone to stand in a certain place, turn their body, move an arm, or remain still while an image is captured.
In practice, patients have different physical abilities and limitations. Some may be experiencing pain or have difficulty moving into a standard position. Technologists must follow appropriate procedures while recognizing what an individual patient can reasonably do.
“You can know the position you need, but you’re still working with a real person,” Fontanez said. “Someone may be uncomfortable or unable to move exactly the way you initially ask. You have to pay attention and communicate.”
That interaction is one reason Fontanez views adaptability as an important part of working in medical imaging. Technical requirements remain important, but patients cannot be approached as though everyone will respond to an instruction in exactly the same way.
Clear Communication Helps Patients Understand What Is Expected
Communication is another significant part of the technologist’s role. Instructions that sound simple to someone working in radiology every day may be unfamiliar to a patient.
Fontanez believes healthcare professionals must be aware of that difference.
“Something can be routine for me and completely new for the patient,” Fontanez said. “I try not to assume that someone understands an instruction just because I’ve given that same instruction many times before.”
That may mean explaining a position differently, letting someone know what will happen next, or checking that an instruction was understood before continuing.
Fontanez also notes that different patients want different amounts of information. Some have questions about each step, while others prefer to receive the necessary instructions and complete the study. Recognizing those differences is part of working directly with people.
“The goal isn’t to overwhelm someone with technical information,” Fontanez said. “It’s to communicate clearly enough that they understand what is expected of them during the study.”
Safety and Attention to Detail Remain Central to Medical Imaging
Many checks in medical imaging are not particularly visible to patients. Technologists follow established procedures for patient identification, the requested study, positioning, imaging practices, and applicable safety requirements.
Certain studies may involve additional considerations. Fontanez’s work with CT imaging, for example, includes her qualification to administer contrast for CT studies.
Fontanez believes one challenge of professional experience is making sure familiarity doesn’t become complacency.
“When you do something regularly, you naturally become more comfortable with it, and experience is important,” she said. “At the same time, you don’t want something being familiar to make you less attentive to the details.”
Efficiency matters in a busy healthcare environment, but Fontanez says there are also situations when taking additional time to verify information or explain an instruction is necessary.
Technology Does Not Replace the Human Side of Radiology
Medical imaging relies heavily on sophisticated equipment, but Fontanez sees the technologist as the connection between that technology and the patient.
Equipment cannot recognize that a patient is struggling to understand an instruction. It cannot independently account for the way an individual is experiencing an appointment or provide the human communication that may be needed during the process.
That responsibility remains with the professionals working directly with patients.
“Technical knowledge matters, but you’re never just working with equipment,” Fontanez said. “There is always a person on the other side of what you’re doing.”
For Fontanez, that is one of the defining aspects of being a radiology technologist. The final medical image may be what remains after the appointment, but producing it involves preparation, communication, positioning, safety procedures, and attention to the individual patient.
Those responsibilities may happen quietly in the background, but they are part of the work every day.
