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.

When Financial Leadership Fails, Working Families Pay the Price
On Friday night, I sat with a group of airline employees trying to make sense of what might come next.

United States, 5th May 2026 – My Spirit Airlines flight had just been canceled. Like many passengers, I was scrambling to find another way to get where I needed to go. But the real story wasn’t the inconvenience. It was the uncertainty in the room.
The employees I spoke with weren’t just talking about schedules or delays. They were talking about their jobs, their families, and what would happen if the company they relied on could no longer sustain itself. You could feel the weight of it—quiet, real, and immediate.
That moment stayed with me.
By Saturday morning, I had made it to Northern Nevada, where I spoke at the Washoe County Democratic Convention in Sparks. Later that day, I spoke again at the Douglas County Democratic Convention in Minden.
In both rooms, I shared a simple belief:
How we manage money says everything about what we value as a state.
I’ve seen this before. In the aftermath of the 2008 financial crisis, Nevada was one of the hardest-hit states in the country. Families lost homes. Communities were shaken. People who had done everything right suddenly found themselves trying to rebuild from nothing.
At that time, I helped lead Nevada’s work with the Startup America Initiative under Barack Obama. I traveled across the state listening to entrepreneurs, small business owners, and community leaders who were trying to put the pieces back together.
The lesson was clear then, and it remains clear now: when financial leadership falls short, it is not just numbers on a page that suffer. It is people.
It is workers wondering how they will make rent next month. It is parents trying to keep stability for their children.
It is communities carrying the long-term consequences of short-term decisions. That is why the role of State Treasurer matters more than most people realize. It is not a ceremonial office. It is a fiduciary responsibility.
The job is to protect taxpayer dollars, manage risk, maintain liquidity, and make disciplined, long-term investment decisions that hold up not just in good times, but in moments of stress.
Because those moments will come.
And when they do, the difference between careful stewardship and careless decision-making becomes painfully clear.
Now, on Sunday, as I reflect on the weekend, I keep thinking about those workers at the airport.
They are not asking for complex financial theories. They are asking for stability. For leadership that takes its responsibility seriously. For decisions that consider not just today’s headlines, but tomorrow’s consequences.
How we manage money is not abstract. It is a reflection of our priorities.
And ultimately, it is a test of whether we are willing to protect the people who depend on those decisions the most.

How to Make Sure Your Car’s AC Keeps You Cool in Arizona’s Extreme Heat
United States, 5th May 2026 – Driving in Arizona during the summer isn’t for the faint of heart. When temperatures climb well into the triple digits, your vehicle’s air conditioning system becomes more than a luxury—it’s a necessity for comfort and safety.

If your A/C isn’t performing at its best, even a short drive can feel unbearable. The key is understanding how to keep your system running efficiently, even under the harshest conditions.
Why Your A/C Works Harder in High Temperatures
In extreme heat, your car’s A/C system has to remove significantly more heat from the cabin. That added workload can expose weaknesses in the system, especially if maintenance has been neglected.
Common issues that show up in hot climates include:
- Reduced cooling power during idle or slow driving
- Increased strain on the compressor
- Faster wear on internal components
- Longer cooling times after starting the vehicle
This is why routine maintenance is critical in places like Tucson and surrounding areas.
Start with a Strong Refrigerant System
Refrigerant is what allows your A/C system to cool the air effectively. If levels are low, the system simply can’t perform.
You may notice:
- Air that feels slightly warm instead of cold
- A/C that struggles to keep up in traffic
- Inconsistent cooling
Even small leaks can lead to reduced performance, so checking refrigerant levels regularly is essential.
Don’t Overlook Airflow
Cold air doesn’t help much if it isn’t moving properly through your vehicle.
Restricted airflow is often caused by a clogged cabin air filter. In Arizona’s dusty environment, this can happen faster than expected.
Replacing your cabin air filter helps:
- Improve airflow through vents
- Boost overall cooling performance
- Reduce strain on your A/C system
It’s a simple fix that can make a noticeable difference.
Your Engine Cooling System Plays a Role
Your A/C system depends on your vehicle’s overall cooling performance. If your engine is running hot, your A/C will struggle to keep up.
Make sure your vehicle’s cooling system is in good shape, including:
- Proper coolant levels
- A functioning radiator
- Working fans and belts
Keeping your engine cool helps your A/C system stay efficient—even in extreme heat.
Smart Driving Habits Can Help
How you use your A/C matters just as much as how you maintain it.
To improve performance:
- Vent hot air by opening doors or windows before turning on the A/C
- Use recirculation mode to cool the cabin faster
- Park in shaded areas whenever possible
- Use sunshades to reduce interior heat buildup
These small habits reduce the workload on your system and improve comfort.
Watch for Early Warning Signs
Your A/C system will usually give you signs before it fails completely.
Pay attention to:
- Weak airflow from vents
- Air that isn’t as cold as it should be
- Unusual noises when the A/C is running
- A/C performance dropping in traffic
Addressing these issues early can prevent more expensive repairs later.
Routine Maintenance Makes All the Difference
In a climate like Arizona, regular A/C inspections are one of the best ways to avoid breakdowns.
A professional check typically includes:
- Inspecting system pressure
- Checking for leaks
- Verifying refrigerant levels
- Evaluating key components
This proactive approach keeps your system reliable when you need it most.
Stay Cool and Drive Safer
Extreme heat isn’t just uncomfortable—it can be dangerous, especially for families, pets, and long-distance drivers.
Keeping your A/C system in top condition helps ensure:
- A comfortable driving experience
- Reduced risk of heat-related issues
- A safer overall ride
In Arizona, a properly functioning A/C system is essential—not optional.
FAQs
1. Why does my A/C struggle more when it’s extremely hot outside?
Higher temperatures make your system work harder to remove heat, which can reduce efficiency if the system isn’t properly maintained.
2. How can I improve my car’s cooling performance quickly?
Start by replacing the cabin air filter, using recirculation mode, and making sure refrigerant levels are correct.
3. How often should I check my A/C system in Arizona?
At least once a year, ideally before summer, to ensure it’s ready for extreme heat.
4. Can engine overheating affect my A/C?
Yes, if your engine runs hot, it can reduce your A/C system’s ability to cool effectively.
5. What’s the most common reason A/C systems fail?
Low refrigerant, leaks, or compressor issues are among the most common causes of A/C failur
