Behind High Energy Consumption of Blockchain: PoS Consensus Mechanism To Be A Solution

Published

on

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.

Financial technology company opens its app in more than 50 countries during FLOW Summit as 500-plus builders develop AI and Web3 products

BANGKOK, Oct. 17, 2026, ZEX PR WIRE  — U-topia, a financial technology company building a self-custody app for everyday money movement, has opened its public beta in more than 50 countries. The company announced the launch at FLOW Summit 2026, held Oct. 15-16 at Avani Sukhumvit Bangkok, five years after U-topia was founded.

More than 700 people attended the two-day launch, including technology entrepreneurs, developers and community members from several countries. The program combined U-topia product demonstrations and company updates with U-Hackathon, a global build program focused on practical AI and Web3 products.

“Five years ago, I set a simple standard: if my mother could not use the product without calling me for help, it was not ready,” said Emmanuel Quezada, founder and CEO of U-topia. “Opening the beta with people from around the world, while hundreds of builders were creating new tools beside us, brought that idea to life. Our goal is to make moving money as simple as sending a message while keeping people in control.”

A public beta designed around everyday use

U-topia is designed to let eligible users hold, send, spend, convert and withdraw digital and everyday currencies through one mobile app. Users can send funds to another U-topia user through a U-Tag, a simple @name that replaces a long wallet address. The company says funds remain under the user’s control rather than being held by U-topia.

The public beta follows private alpha and closed beta testing with community members and ambassadors. Feature availability varies by country. Account opening, card issuance and transactions remain subject to age requirements, identity verification, partner rules and local law. U-topia is not a bank or card issuer; card and local currency services are provided through licensed partners where available.

U-Hackathon brings global builders to Bangkok

FLOW Summit also hosted U-Hackathon on Oct. 15-16. Organizers said the event attracted more than 500 hackers and builders from around the world. Teams worked through a 24-hour build period with product, engineering and design mentors before presenting working prototypes in two tracks: artificial intelligence and Web3. The program extended the app launch into a working forum for new products, technical collaboration and international builder participation.

The competition recognized three teams in each track. Organizers valued the combined awards at more than 2.5 million Thai baht, including the advertised THB 1 million core prize pool, partner bounties and technology credits. UBotPay, an AI-powered payment agent built for Web3, won first place in the Web3 track. U-Reach, an AI-powered marketing, sales and customer relationship management platform, took first place in the AI track.

U-Hackathon was sponsored by ElevenLabs, Tokenomist AI and DTC Group, in association with Avalanche, Team1 Thailand, Yellow.com, ContributionDAO, CUBS Chula and Hooray. Judges selected projects on merit, and members of the U-Center DAO community voted live for the grand prize.

The summit also included a preview of U.bot, a related AI venture from members of U-topia’s founding team. U.bot is being developed as a user-controlled orchestration layer that can select among AI models and coordinate specialized agents. Its long-term roadmap aims to create a more capable personal AI experience with characteristics the team associates with superintelligence; those advanced capabilities are planned and are not currently available.

About U-topia

Founded on Oct. 16, 2021, U-topia is a financial technology company building a self-custody mobile app intended to help people hold, send, spend, convert and withdraw digital and everyday currencies while retaining control of their funds. U-topia is not a bank and does not issue cards. Availability and features vary by country and are subject to partner requirements and local law. Learn more at www.u-topia.com.

From Karmayogi to the World Stage: Dr. Hemant Garg Wins “Excellence in AI for Public Policy”, Charts India’s Path to the AI Big League

Published

on

Civil servant, researcher and AI pioneer tells the 3rd World AI Summit, Bengaluru, that people-first, sovereign AI can make India a global AI leader

Bengaluru, India, 16th October 2026, ZEX PR WIRE  — Dr. Hemant Garg, Deputy Director (Legal), Employees’ State Insurance Corporation (ESIC), Ministry of Labour and Employment, Government of India, received the “Excellence in AI for Public Policy” award at the 3rd World AI Summit in Bengaluru on 14–15 October 2026, placing an Indian public-policy voice at the centre of the global debate on how AI should serve people.

Dr. Garg described all of his work, from AI agents for government to AI-led labour law outreach, as an effort to help realise Hon’ble Prime Minister Shri Narendra Modi’s vision of Viksit Bharat@2047, under the leadership of Hon’ble Union Labour and Employment Minister Dr. Mansukh Mandaviya, whose Shramev Jayate reforms, Labour Codes and Ease of Doing Business drive set the direction. The goal, he said, is an Atmanirbhar Bharat in AI, built on a Bharat AI Stack: Indian large language models such as Sarvam, the Bhashini platform serving citizens in their own languages, and home-grown agents and talent under the IndiaAI Mission, taking India into the global AI league.

Held with Digital India, the National e-Governance Division (NeGD) and the Karnataka Digital Economy Mission (KDEM) as partners in Bengaluru, India’s startup, IT and now AI capital, often called India’s Silicon Valley, the Summit was themed “AI for All: Accelerating India’s Journey Towards Inclusive, Responsible and Future-Ready AI”.

The award honours his creation in 2023 of “IFSCA Karmayogi”, the first AI agent at the International Financial Services Centres Authority (IFSCA), GIFT City, and his research on AI in anti-money laundering, the Labour Codes and algorithmic management of gig workers.

On the panel “AI for All – India’s Journey to a Sovereign, Inclusive AI Future”, with Shri Aman Mittal, IAS, Dr. BVRC Purushottam, IAS and Prof. (Dr.) T. G. Sitharam, former Chairman, AICTE, moderated by Dr. Ravi Gupta, Dr. Garg said inclusive AI must include the worker, and that India can blend Europe’s rights-based approach, US-style audits and Singapore’s skilling model through its Labour Codes, the DPDP Act and e-Shram.

His keynote, “AI, Employment & Skills: Building a Future-Ready Workforce for India”, presented as “From Files to Foresight”, began with a worker disabled in an accident, or a family that has lost its breadwinner, whose care and pensions depend on ESIC, EPFO, the Ministry of Labour and Employment and the National Health Authority. “The true test of AI in government is how quickly that family receives its benefits, and whether it is treated with dignity on the way,” he said.

He traced three waves of governance: e-Governance, which put paper online; Digital Governance, built on India’s digital public infrastructure; and now AI-enabled Intelligent Governance, where benefits reach eligible citizens without their having to apply.

Dr. Garg propounded that AI will change tasks first, then jobs, then institutions and the workforce, and called for institutions for AI governance, impact assessment and exposure mapping to curb job attrition, support reskilling and compensate workers in transition. e-Shram, ESIC and EPFO, now reaching gig and platform workers, can extend social security to those left out, while indigenous models such as Sarvam and Bhashini can grow home-grown AI talent under the IndiaAI Mission.

Government AI, he said, must be lawful, explainable and accountable; “a pattern is not proof”; and India must guard against a new colonisation “not by ships, but by servers”. He proposed “Five Ts”: Trust, Transparency, Talent, Thin and safe data, and Tested-then-scaled.

An LLB, LLM and Ph.D., and an IIT Delhi CTO Programme alumnus with nearly two decades in public service, including Punjab’s Department of Cooperation, Dr. Garg has researched digital governance in governments and cooperatives extensively; his work is published internationally, taught in universities and presented at Oxford, Harvard and Cambridge.

“Not artificial intelligence replacing governance, but intelligent governance that remains deeply human,” he concluded.
