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.

NexFabric Debuts Human-Verified Industrial AI for Laser Cutting at EuroBLECH 2026
Hannover, Germany, October 21st, 2026, FinanceWire
Italian-built NexCut helps sheet metal shops tell a settings problem from a machine fault, and gives newer operators a guided way to learn what veterans know.
NexFabric today presented NexCut in Europe for the first time, at EuroBLECH 2026 on the stand of Esautomotion (Euronext Growth Milan: ESAU), Hall 15, Stand E28, after a first showing at CIIF in Shanghai. NexCut is the first laser-cutting application of the NexFabric industrial AI platform. Built in Italy, it pairs AI-assisted analysis with checks the operator confirms, so manufacturing teams can diagnose production problems without handing the decision to the machine.
Factories are losing the people who know their machines best. In Germany, 12.9 million workers, close to 30% of the workforce, will reach retirement age by 2036, according to the Federal Statistical Office. In Italy, companies reported difficulty filling 47.8% of planned hires, with CNC operators and welders among the hardest roles to fill, according to a CGIA analysis of Unioncamere Excelsior data. NexCut is built for that handover. A junior operator learns the diagnostic routine on the job, guided step by step, instead of spending years picking it up beside a veteran. Every diagnosis is saved as a procedure the next shift can reuse.
NexCut addresses a practical challenge in laser cutting: telling a problem with process settings from an issue with the machine or its hardware. Take a common case. Dross starts building on the underside of the parts. A less experienced operator may slow the cut or raise gas pressure. If the real cause is a dirty lens or a worn nozzle, that change wastes material and the fault stays. NexCut has the operator check the hardware first and confirm what they find. If there’s a hardware problem, it won’t clear the machine to run until it’s fixed.
Here’s how it works. Each laser cutter gets its own NexCut kit: a touchscreen operator station at the machine and a connected hardware module that brings in process signals from the cutter. When cut quality drops, NexCut combines those signals with physical checks the operator carries out and confirms, covering the lens, gas, focus position, cutting height, nozzle and machine stability. It narrows down the likely cause, explains why, and points to the fix. The operator makes the call. Every step is logged, so the process stays traceable and repeatable, and a central dashboard gives production managers a view across all connected machines.
“Running a laser cutter well takes years of experience, and even experienced operators still make mistakes,” said Stefano D’Andria, CEO & Founder of NexFabric. “NexCut is there to help and teach. Any operator can use it, whatever their experience, and the decision always stays with the person at the machine.”
The first proof of concept is running under real operating conditions at Soluzioni Markaurelio S.r.l. in Avezzano, Italy. It is testing NexCut against clear targets: an average guided diagnosis of 7 to 11 minutes, a 50 to 70% reduction in setup time, startup scrap and machine stoppages, and new operators working on their own within two to four weeks.
NexCut is built for manufacturers across Europe that run laser cutters. Operators get step-by-step guidance at the machine. Owners keep the know-how in-house when experienced staff leave. NexFabric plans to work with multiple industrial partners and dealers, broadening access while preserving manufacturer choice.
“Industrial AI must increase human decision-making capability, not replace it,” D’Andria added. “We’re starting in Italy, where our R&D is, and building for factories across Europe.”
D’Andria is at EuroBLECH through October 23 and available for interviews at the stand. To book a time, contact Orian Tal at orian@thepitch.media.

Rabbi Steve Karro’s Message: Give Something Back Before the Holidays Arrive
Miami, Florida, 21st October 2026, ZEX PR WIRE, Rabbi Steve Karro is asking his community to make one concrete act of giving part of their holiday preparation this year.
A season that asks something of us
Every year, the weeks before the holidays fill up fast. Cleaning, cooking, travel, gifts. Rabbi Steve Karro has spent decades studying the parts of Jewish tradition that ask us to slow that rush down and make room for someone else.
As a rabbi and scribe based in Miami Beach, Florida, he sees the holiday season as more than a checklist of preparations. He sees it as a yearly reminder to look outward.
“Every situation, I ask what the Creator expects from me,” Rabbi Karro said. “Before the holidays, the answer is usually simple. Give something. Give it now, not later.”
The invitation
Rabbi Karro is encouraging people in his community to take on a simple practice ahead of this holiday season: one act of direct giving to someone nearby, done before the holiday itself begins, not during it and not after.
“It does not need to be large,” he said. “It needs to happen before the holiday starts, not get folded into it. That timing matters. It says the giving came from you, not from the season telling you to.”
Why the order matters
Rabbi Karro draws a distinction between giving that happens because a holiday requires it, and giving that happens because a person chooses it ahead of time.
“When you give during the holiday, you are following the calendar,” he said. “When you give before it, you are following your own decision. Both are good. But the second one changes something in you.”
He points to family life as the frame he uses to think about this.
“When your closest family is happy, and the people around them are happy too, that is the real measure,” he said. “Giving before the holiday is one way to widen that circle a little further out from your own table.”
What giving back can look like
Rabbi Karro is not prescriptive about the form giving should take. He suggests people start with someone they already know needs something, rather than searching for a cause far from home.
“Start close,” he said. “A neighbor. Someone at your synagogue. Someone in your family nobody has checked on in a while. The person right in front of you is usually the answer.”
He also encourages people to think about what they can give beyond money: time, a skill, a meal, a conversation.
“Everyone has something they know how to give,” he said. “Teaching, cooking, fixing something, listening. Find yours and give it before the holiday, not during it.”
A practice, not a one-time gesture
Rabbi Karro hopes this becomes something people return to each year, not a single gesture tied to this season alone.
“I want to see this duplicated,” he said. “Not from one person, but from many people who hear about it and decide to do their own version. That is how something small becomes something that lasts.”
He also connects the practice to teaching, which he considers central to his work as a rabbi and scribe.
“Teaching what I have learned means more people can do good for the people around them,” he said. “That is the whole point.”
About Rabbi Steve Karro
Rabbi Steve Karro is a rabbi, scribe, artist, and teacher based in Miami Beach, Florida. Born in Russia, he moved to Jerusalem at age 10 and began his Hebrew education there. At 13, he continued his studies at Yeshiva Ponovich in Bnei Brak, and by 19 he had earned his rabbinic certificate and diploma. Rabbi Karro works internationally as a Judaica calligraphy and oil painting artist, and as a scribe specializing in restoring old Torah scrolls, writing new Torah scrolls, mezuzahs, and tefilin, and checking Torah scrolls, mezuzahs, and tefilin for communities around the world.

Sundas Naqvi: Moving Cities Does Not Mean Leaving Your Sound Behind
Chicago, Illinois, 21st October 2026, ZEX PR WIRE, Chicago jazz and folk vocalist Sundas Naqvi shares the lesson she learned when she moved her music from southern England to the American Midwest, and what she now tells other musicians who relocate.
Leaving One Sound for Another
Sundas Naqvi grew up in southern England, singing in school choirs and small community concerts before she found jazz and folk music at university. That sound, built around British choir traditions and acoustic folk, was the only musical language she knew.
In her late twenties, she moved to Chicago. The city had its own musical history, built on blues, jazz clubs, and a folk scene that worked differently than anything she had performed in before. She had to figure out where her voice fit inside it.
“I thought I was bringing a finished sound with me,” Naqvi says. “What I actually brought was a starting point.”
What Changed, and What Did Not
Naqvi did not rebuild her style from scratch. The jazz standards she loved stayed. The folk influences she picked up in England stayed too. What changed was how she used them.
Chicago’s jazz lounges rewarded a different kind of phrasing than the rooms she had performed in back home. Its coffeehouses wanted something quieter and more conversational. Private events and seasonal festivals each asked for their own pacing. She learned to read a room the way she once read sheet music.
“The songs didn’t change,” she says. “I changed how I told them.”
That shift shaped the storytelling that now runs through her sets, songs built around resilience, family, and the small moments that connect strangers in a room. Naqvi says those themes came less from any single influence and more from paying attention to what audiences in her new city responded to.
The Lesson She Tells Other Musicians
Naqvi now volunteers with youth music education programs around Chicago, leading beginner songwriting workshops and vocal sessions. She says the musicians she meets, young and experienced alike, often make the same mistake she almost made: treating a new city, a new audience, or even a new venue as a place to perform an existing sound rather than a place to grow one.
“You don’t have to choose between where you came from and where you are,” she says. “But you do have to let the new place change you a little. If it doesn’t, you’re not really there yet.”
Her advice to musicians who relocate, or who are simply trying a new room for the first time, is to treat the first several performances as listening exercises. Watch how people react to pacing, silence, and song choice before deciding what to keep and what to adjust.
“A song that works in one room can fall flat in another,” Naqvi says. “That’s not a failure. That’s information.”
Still Bringing England Into the Room
Naqvi returns to England when she can, to see family and lifelong friends. She says those visits keep her connected to where her musical instincts started, even as her sound has grown around Chicago’s own traditions.
She still reads British literature alongside contemporary fiction, a habit she picked up long before she ever sang jazz. She spends free time exploring Chicago’s older neighborhoods and photographing its architecture, work she says sharpens the same instinct for detail she uses when she is writing a song.
“Noticing a building’s small details isn’t that different from noticing what makes a lyric land,” she says. “Both come down to paying attention to things most people walk past.”
That habit of attention, more than any single technique, is what she now tries to pass on in her workshops: slow down, notice the room, and let the place you are in actually shape the art you make there.
About Sundas Naqvi
Sundas Naqvi is an independent jazz and folk vocalist, songwriter, and occasional vocal coach based in Chicago, Illinois. She performs at neighborhood jazz lounges, coffeehouses, private events, and seasonal festivals throughout the city, blending jazz standards with contemporary folk influences. She also volunteers with youth music education programs, leading beginner songwriting workshops and vocal sessions for children in Chicago’s local arts community.
