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.

Velocity Capital Group’s Jay Avigdor Announces Book Pre-Orders and Upcoming Podcast “Chewing Glass”
New York, New York, October 28th, 2026, FinanceWire
Need It, Don’t Want It, a business memoir told in reverse, publishes December 8, 2026, and the podcast will feature founders on the setbacks behind their companies.
Jay Avigdor, Chairman and Chief Executive Officer (CEO) of Velocity Capital Group, today announced that his book, Need It, Don’t Want It: The Business Lessons No One Asks for, No One Tells You, but Everyone Needs, is available for pre-order on Amazon ahead of its December 8, 2026 publication by Advantage Books. Avigdor also announced Chewing Glass, an upcoming podcast about the challenges of being an entrepreneur, premiering in November, 2026. Both projects focus on the hard, gritty side of building a business.
The book tells the story of Velocity Capital Group in reverse. It opens in Chapter 12, with the company established, and works back through setbacks with financing, staff and the pandemic to the company’s first days. The frame is a teenager who asks Avigdor to mentor him and is taught the lessons from the end to the beginning. Each chapter closes with takeaways and “Need It Notes” that ask readers to apply the ideas to their own businesses.
“If you can take a faster punch, and you can take more punches than the other guy, that’s who’s going to win,” said Jay Avigdor, Chairman and CEO of Velocity Capital Group.
In the book, Avigdor writes about “the days when I had to question whether I could turn my ambitions into reality.”
In an early trade review, BookLife by Publishers Weekly wrote: “Avigdor’s stories and enthusiasm give Need It, Don’t Want It welcome heart and humanity. This high-energy account cleverly lays bare the lessons founders learn when facing uncomfortable problems.” IndieReader called the book “an honest, structurally inventive account of building a business from the ground up that proves most persuasive in the chapters where the lessons come from various setbacks and failures.”
Chewing Glass takes its name from Avigdor’s description of what running a company feels like: being a CEO, he says, is mostly chewing glass. Rather than asking guests how they succeeded, the show will ask founders and business owners about what nearly ended their businesses, including missed payroll, bad hires, bad investors, and the setbacks founders usually keep private, and how they got through them.
“If you’ve gone through a world of pain and you’re still standing, I want to hear your story and how you got through it,” Avigdor said. “We’re going to talk about the pain, the blood, the sweat, the tears, the hardship.”
For Avigdor, the measure of a founder is what the business did for its people, not cars or money.
“Show me you emptied your personal bank account to make sure your employees got food on the table,” he said.
Need It, Don’t Want It will be published in hardcover and Kindle editions.

Velaris Markets: an MT5 broker and a prop service, live since July 2026
Each service has its own terms; the prop service uses demo accounts and is not a brokerage service.
Castries, Saint Lucia, October 28th, 2026 – Velaris Markets operates two services under one brand. Its brokerage offers CFDs on forex, indices, commodities and crypto on MetaTrader 5. Its prop service runs trading challenges on simulated accounts of up to $100,000: traders who pass and verify their identity receive a funded simulated account and 80% of the profit on that account, paid as a reward. Both services launched in July 2026.

Brokerage: two account types, no minimum deposit
The Standard account has spreads from 1.2 pips and no commission. The ECN account has spreads from 0.0 pips plus a commission of $7 per lot round turn on forex and metals. There is no minimum deposit. Leverage goes up to 1:200 on FX pairs and is lower on other asset classes. Clients deposit by card or in crypto (BTC, ETH, USDT, USDC). The client portal also offers copy trading, where a client’s own account follows a strategy provider, and Money Management (PAMM) pools run by pool managers.
Prop service: simulated accounts from $2,500 to $100,000
The prop service runs 1-Step challenges with account sizes from $2,500 to $25,000 and 2-Step challenges from $2,500 to $100,000, all on MT5, for a one-time fee starting at $29. There is no time limit to pass. A trader who passes and completes identity verification receives a funded account of the same size. Payouts run in 14-day cycles, and each payout request receives a decision within 48 hours. On the 2-Step challenge, the fee is returned with the first payout.
“Our experience in the industry shows that established firms in this business run both a brokerage and a prop structure, because together they build more trust in the brand,” said Yasen Dimitrov, Director of Velaris Markets. “A trader with a few hundred dollars has two options: trade that money directly, or pay a fee to prove a strategy on a larger simulated account. At Velaris the same trader can open a broker account with no minimum deposit, or start a $2,500 2-Step challenge for $29, where the most they can lose is the fee.”
Both services use the same support model. Live chat is open at any hour: an AI assistant answers first and hands over to the support team, which works Monday to Friday. The aim is to resolve the issue during the chat rather than open a ticket and reply later.
The brokerage is available at velarismarkets.com and the prop service at prop.velarismarkets.com. Neither service is available to citizens or residents of the United States or of sanctioned jurisdictions; the full lists are in each service’s terms.
About Velaris Markets
Velaris Markets Limited is a company incorporated in Saint Lucia in January 2026 under company number 2026-00083. It is not licensed by a financial regulator. Client funds at the brokerage are held separately from the company’s operating funds. The prop service is not a brokerage service and is not a regulated financial service; it is an evaluation program run on demo accounts.

FinSight Ventures Launches $100 Million Physical AI Index Fund
San Francisco, US, October 28th, 2026, FinanceWire
FinSight Ventures Launches $100 Million Physical AI Index Fund, Targeting the Third Wave of Artificial Intelligence
FinSight Ventures, a global technology investment fund with $1B+ AUM and a portfolio of 13 unicorns, announced the formation of the FinSight Physical AI Index Fund — its second thematic index fund and the first institutional vehicle dedicated exclusively to the Physical AI segment that interacts with the physical world.
The Fund targets a concentrated portfolio of 10–12 leading companies across four Physical AI segments — Robotics, AI for Science, Foundation Layer, and Hardware & Infrastructure — with an aggregate target capitalization of $5.7T by 2031.
“Physical AI is not a trend, but the third structural wave of artificial intelligence,” said Alexey Garyunov, Founder and General Partner of FinSight Ventures. “Perception AI gave machines eyes and ears. Generative AI gave them language. Physical AI gives them agency in the real world. We are now at the same inflection point that defined OpenAI and Anthropic in 2019 — except what is being built is an order of magnitude larger.”
The Fund’s investment thesis rests on a structural labor shortage that no conventional policy instrument can address at scale. According to UN projections, the working-age population across East Asia, Europe, and the United States will contract by 342 million people by 2050 — a cohort representing approximately 55% of global GDP. Migration flows are slowing down. Labor participation rates in advanced economies have reached their effective ceiling.
“We modeled every mechanism available to close a 342-million-person labor gap,” said Garyunov. “Offshoring runs against reshoring policy — the CHIPS Act, the IRA, the EU Chips Act. Migration is contracting, not expanding. Labor participation in developed markets is already at 74–80%. The only channel with growing capacity is automation through Physical AI. This represents a demographic inevitability rather than a simple technology bet.”
Market Context
According to PitchBook data, Physical AI’s share of global venture financing has grown from 0.8% in 2016 to 12% in 2025, with investment volume rising from $2.0B to $64.7B over the same period and reaching $72.2B in the first half of 2026 alone. The top 20 global venture funds have completed 345 transactions in the segment since 2022, two-thirds of them after January 2024.
The humanoid robot fleet is projected to reach between 330 million and 1 billion units by 2050, displacing an estimated $19.8T in annual labor value. At a 15–20% revenue capture rate and a 7.5–10x P/S multiple, the Physical AI sector is projected to carry a market capitalization of $22–40T by 2050.
“The enabling technologies converged in 2023–2025,” said Garyunov. “NVIDIA’s Cosmos world models solved the data problem — robots can now train millions of times faster in simulation than in the physical world. VLA models solved the intelligence problem — a single model sees, understands natural language, and acts. The EV supply chain solved the cost problem. The infrastructure for a Physical AI industry is in place. What follows is deployment at scale.”
About FinSight Ventures
FinSight Ventures is a global technology investment firm founded in 2012, with offices in the United States, India, and Cyprus. The fund manages $1B+ in assets across a portfolio that includes 13 unicorns. Portfolio companies comprise Klarna, Uzum, Razorpay, Cashea, Rappi, Punto Pago, and more than 80 other companies. Last year, FinSight launched the FinSight Gen AI Index Fund, which invested in 13 companies that represent the American AI Sector including Together AI, Fin AI, Crusoe, Glean among others.
