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.

CGTN Documentary: The Silver Ball: A Journey Beyond – Sport Forges Enduring People-to-People Ties for China-US Relations

People to People exchange creates an environment… making it easier for our political leaders to come together.
– Judy Hoarfrost – Ping Pong Diplomat
Amid rapid global changes and profound international shifts, China-US relations face severe challenges including a trust deficit and perception gaps. As a universal language transcending borders, cultures and political divisions, sport has long served as an important bridge for friendship and understanding.
China’s President Xi Jinping has stressed that the foundation of China-US relations is laid by the people, and its future will be forged by the youth. He also highlighted sport’s unique role in cross-cultural communication. To mark the 55th anniversary of China-US Ping-Pong Diplomacy and advance the initiative to invite 50,000 American youth to China over five years, CGTN has produced a documentary, The Silver Ball: A Journey Beyond.
The documentary revisits the historic events of 1971 and what became known as Ping-Pong Diplomacy. It then explores how sport continues to connect people today. Through table tennis, martial arts and pickleball, it tells the stories of exchanges between Chinese and American people, especially the younger generation. It shows how grassroots interaction nurtures friendship, eases differences and builds mutual trust, demonstrating sport’s unique power to rise above race, nationality and ideology.
Jointly produced by Chinese and US teams, the documentary is directed by CGTN North America correspondent Dan Williams and filmed across major cities in both countries. A touching highlight is the reunion of Ping-Pong Diplomats Liang Geliang and Judy Hoarfrost at Beijing’s Capital Indoor Stadium, where they competed together 55 years ago.
The film features exclusive interviews with key witnesses and participants. Liang Geliang, Zheng Minzhi, Judy Hoarfrost and Connie Sweeris — all participants of the 1971 exchange — recalled the historic event and emphasized that people-to-people friendship remains essential. Zheng Minzhi noted that the spirit of Ping-Pong Diplomacy must be passed onto younger generations to maintain vitality.
The documentary also focuses on youth exchanges, particularly pickleball, which has become a new bond between Chinese and American teenagers. Jeffrey Sullivan, leader of a US student delegation, wrote to President Xi in 2025 to express gratitude for the youth exchange initiative. In his reply, President Xi praised pickleball as a new link for friendship. Sullivan said sport builds emotional ties and lays a solid foundation for state-to-state relations.
Martial arts also appears as a cultural bridge. Steven Zhang, a Chinese American kung fu coach, and his young students show how traditional culture helps connect young people across nations.
In an exclusive interview, Thomas Bach, Honorary President of the International Olympic Committee, said sport can open doors for diplomacy, unite people and prove that humanity can live in peace.
Released on April 10, 2026, the documentary sends a positive message at a critical time for bilateral relations. It underlines that people-to-people exchanges are the fundamental foundation of bilateral ties, and that sport remains one of the most stable and powerful forces to bring the two countries closer together.

Protecting Rural America: Why Environmental Testing USA Is Leading the Call for Transparency, Safety, and Science-Based Oversight in Renewable Energy Development

United States, 11th Apr 2026 – For more than a decade, it often felt like it was just the two of us, Dan and me, facing the world with more questions than answers. We were used to doing our own research, trusting our instincts, and verifying everything for ourselves. But nothing prepared us for the day we received a letter informing us that a large renewable energy facility had purchased the land next to ours.
We were not opposed to solar panels or renewable energy. What we were opposed to was not knowing what was about to be built beside our home, our water, and our community. So we did what we have always done: we started asking questions.
What we found changed everything.
As we dug through studies, public records, and technical documents, we discovered inconsistencies, missing information, and a troubling lack of environmental testing requirements. There was no baseline testing required at any level of government. No one was required to test the soil or groundwater before construction. No one was required to test during construction. No one was required to test during operation. And no one was required to test after decommissioning. If contamination occurred, there would be no way to prove it.
That was the moment when everything shifted.
Dan began connecting what he had learned over twenty years in the construction field with what we were uncovering. Components used in solar panels, wind turbines, battery energy storage systems, and data centers can contain substances such as PFAS, lead, and cadmium. These contaminants are known to persist in the environment and pose risks to human health. Our research also revealed that companies sometimes minimized their use of hazardous materials on official applications. Without independent testing, communities had no way to verify claims or protect themselves.
When the day of the public hearing arrived, I brought a prepared speech. Dan brought his usual fire. And the community brought something we had never experienced before: unity. People from all walks of life stood together, asking for transparency, accountability, and basic environmental protections. That night, something shifted. It was no longer just us. It was neighbors standing with neighbors. It was rural voices demanding to be heard.
And that is the moment Environmental Testing USA was born.
Our Mission: Testing the air, water, and soil one acre at a time, for future generations to enjoy the planet we all reside.
Environmental Testing USA is a national nonprofit dedicated to protecting soil, water, and public health through independent, science-based environmental testing. Across the United States, rural communities face the same challenges we did. Many rely heavily on groundwater. Many depend on healthy soil for agriculture and livestock. Many have limited regulatory oversight. Industrial-scale renewable projects are expanding rapidly, yet there are no baseline testing requirements, no long-term monitoring, and no independent verification of company claims.
ETUSA exists to fill that gap. We provide education, advocacy, and a responsible testing framework that any community, county, or state can adopt.
Scientific studies have shown that components used in renewable energy infrastructure may contain PFAS, lead, and cadmium. PFAS are persistent and mobile and have been linked to cancer and immune suppression. Lead is a neurotoxin with no safe exposure level. Cadmium is a carcinogen that can leach under certain conditions. These findings do not mean renewable energy is harmful. They mean renewable energy must be responsibly managed, just like any other industrial technology.
ETUSA advocates for a simple, common-sense testing framework. Environmental conditions should be documented before construction begins. Testing should continue throughout construction. Facilities should be monitored annually during operation. And testing should continue after decommissioning to ensure the land and water remain safe. This approach protects public health, ensures regulatory compliance, provides transparency, prevents costly remediation, and gives communities the data they need to make informed decisions. Baseline testing is especially important because it removes any excuse for companies to deny responsibility for new contamination.
Independent testing matters because across the country, renewable energy companies have submitted applications claiming they use no hazardous materials even when technical documents and industry standards indicate otherwise. Misrepresentation on government applications is not a small issue. It can lead to fines, contract termination, legal consequences, and a loss of public trust. Independent testing protects both communities and responsible developers by ensuring that environmental data is accurate, transparent, and verifiable.
ETUSA also supports a smarter path forward by encouraging the siting of industrial-scale renewable projects on brownfields, land already impacted by previous industrial use. Brownfields offer existing infrastructure, reduced environmental risk, lower community resistance, and opportunities for land restoration and productive reuse. This approach supports renewable energy growth while protecting the land rural families depend on.
Environmental Testing USA serves rural communities across the nation, local governments and planning departments, farmers, ranchers, landowners, schools, nonprofits, and anyone seeking clear, science-based environmental information. Our goal is simple: empower communities with data, not fear.
Environmental testing is expensive. PFAS testing alone can cost hundreds of dollars per sample. Lead and cadmium testing add more. Building a community-accessible laboratory requires equipment, staff, and ongoing operational support. Every donation helps us conduct independent testing, build public data tools, create educational materials, train communities to understand environmental reports, advocate for responsible renewable energy development, and expand our services nationwide. Your support ensures that no rural community has to stand alone the way we once did.
We do not want to fight renewable energy companies forever. We want to work with them, using real data, real science, and real transparency. We believe in a future where renewable energy and rural communities thrive together, where environmental testing is standard practice, where companies are honest and accountable, where communities have access to the information they need, and where decisions are made with clarity rather than guesswork.
Environmental Testing USA was born from a moment of community strength. Today, we carry that strength forward for every rural community in America.
Environmental Testing USA stands at a pivotal moment for rural communities across the country. As large-scale energy projects accelerate, the need for independent, science-driven testing has never been more urgent. ETUSA remains committed to transparency, public safety, and giving every community no matter how small the data they need to make informed decisions.
Our work is powered by people who believe that truth, accountability, and environmental stewardship matter. Whether you’re a resident seeking clarity, a local leader navigating complex regulations, or a community member who simply wants to protect the place you call home, ETUSA is here to help.
