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.

Tel Aviv–Jaffa business leader Said Abulafia shares lessons from a historic Arab family-owned bakery that has served customers for nearly 150 years.
Tel Aviv–jaffa, Israel, 22nd July 2026, ZEX PR WIRE— Most businesses do not make it to ten years. According to the U.S. Bureau of Labor Statistics, only 34.7% of private-sector establishments born in 2013 were still operating in 2023. Family businesses face another challenge: only about 30% transition to the second generation, and roughly 12% remain viable into the third.

That makes Abulafia Bakery’s history unusual. Founded in Jaffa in 1879, the historic Arab family-owned bakery has operated for nearly 150 years through political change, economic pressure, shifting customer habits, and several generations of family leadership.
Said Abulafia believes the bakery’s long history offers practical lessons for modern businesses trying to survive.
“When people hear that the bakery started in 1879, they think about history,” says Abulafia. “I think about responsibility. Every generation had to make decisions that kept the business alive. That is the real lesson.”
Longevity Starts With Trust
For Abulafia, the bakery’s staying power begins with customer trust. Customers return because they know what to expect. They recognize the product, the place, and the experience.
Modern businesses often focus on attention. Abulafia believes trust matters more.
“A customer who comes once is important,” he says. “A customer who comes back with their children or grandchildren tells you something much deeper. It means the business became part of their routine.”
That kind of loyalty is not built by a single strong campaign. It is built through years of consistency.
Consistency Is Not Old-Fashioned
In a fast-moving business environment, consistency can sound plain. Abulafia sees it differently.
For a bakery, consistency is operational. Ingredients must be reliable. Production has to stay controlled. Service has to feel familiar. Small changes are noticed quickly.
“If something changes in the product, regular customers know,” he says. “They may not explain it in technical terms, but they feel it. That is why consistency is not just a nice idea. It is part of the business model.”
Adaptation Without Losing Identity
Abulafia says one of the biggest challenges for heritage businesses is knowing what to change and what to protect.
A business founded in 1879 cannot operate exactly as it did in earlier generations. Costs change. Customer behavior changes. Competition changes. Operations must improve.
At the same time, moving too far from the core identity can weaken what has kept the business going.
“You have to modernize carefully,” says Abulafia. “If you change everything, you lose the reason people trusted you. If you change nothing, you fall behind. The work is finding the line between the two.”
What Modern Businesses Can Learn
Abulafia believes the bakery’s history offers several lessons that extend beyond hospitality.
First, businesses need a clear core. They should understand what customers return for and protect it.
Second, growth should not come before stability. A weak system becomes harder to manage as it expands.
Third, businesses should listen to repeat customers. Long-term customers often notice operational problems before leadership does.
“People talk a lot about innovation,” he says. “But sometimes the best information comes from a customer who has been coming to you for 20 years and notices when something feels different.”
Pressure Reveals Weakness
The bakery has faced many periods of uncertainty, including the COVID-19 pandemic, supply disruptions, rising costs, and fluctuating demand. Abulafia says those periods forced the business to simplify and strengthen its systems.
“When conditions are easy, you can ignore problems,” he says. “When pressure comes, every weakness becomes visible. That is when you either fix the system or keep repeating the same mistakes.”
For Abulafia, pressure is not only a challenge. It is a test of how well a business is built.
A Call to Study Businesses That Last
Abulafia encourages entrepreneurs, operators, and family business owners to study long-running businesses, not only fast-growing ones.
Many modern business stories focus on rapid scale. Abulafia believes there is equal value in studying enduring companies.
“A business that lasts for generations has already answered questions many newer businesses are still trying to solve,” he says. “How do you keep trust? How do you adapt? How do you stay useful to people over time?”
Call to Action
Abulafia encourages business owners to take practical steps:
-
Identify what customers truly return for
-
Protect the parts of the business that create trust
-
Make changes gradually and measure the impact
-
Listen closely to long-term customers
-
Build operations that can survive difficult periods
“Longevity is not one big decision,” he says. “It is many small decisions made well over time.”

Knot, the leading merchant connectivity platform, has announced its partnership with RBC, Canada’s largest bank, to make RBC cards the default payment method for millions of cardholders wherever they spend. Using Knot’s CardSwitcher, RBC cardholders can set their RBC card as the saved payment method at their favorite merchants directly from the RBC mobile app, without manually entering card details. The partnership marks Knot’s first expansion beyond the United States.
Keeping RBC Top of Wallet
One of the hardest moments in payments is the first one. When a cardholder gets a new RBC card, putting it to use means hunting down every merchant where a card is already saved and updating each one by hand, so a new card often sits idle for weeks before it sees real spend. The partnership removes that friction. From the RBC app, cardholders add their RBC card to their preferred merchants in a few taps and set it as the saved payment method at the places they already spend, from the day the card is in hand.
For RBC, that means a card that goes to work immediately instead of waiting to be activated across a cardholder’s everyday spend. Placing the card as the default at the merchants cardholders use most keeps it top of wallet, turning a new RBC card from an occasional choice into a go-to payment method from the start and driving repeat spend and deeper loyalty to RBC.
Expanding into Canada with the Country’s Largest Bank
For years, Knot has built the merchant connectivity layer across the United States, linking the people, financial institutions, and merchants behind everyday spend. RBC is where that infrastructure goes international for the first time. Canada is Knot’s first market beyond the U.S., and launching it with the country’s largest bank sets the standard for every market that follows.
RBC did not become Canada’s largest bank by standing still. They move early, they invest in their clients, and they push the industry forward. That is exactly the kind of partner Knot wants to build alongside, and the reason RBC is the right first step into a new market. Bringing CardSwitcher to Canadian cardholders is the start of a longer roadmap, both for what Knot and RBC build together and for where Knot goes next.
