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.

Sheryar Shah Predicts Major Decline in Hong Kong Graduate Entry-Level Jobs by 2028

Published

on

Sheryar Shah, Head of AI Growth at sher.hk, highlights a 55% year-on-year drop in Hong Kong graduate entry-level vacancies — the lowest in five years — as companies adopt AI for routine junior tasks.

Hong Kong S.A.R., 9th Mar 2026 – Sheryar Shah, Head of AI Growth at sher.hk, has drawn attention to a notable trend in Hong Kong’s graduate employment market: full-time entry-level graduate vacancies have fallen by approximately 55% year-on-year — reaching the lowest level recorded in five years — as companies increasingly adopt generative AI and automation tools for routine junior tasks.

“The entry-level pathway that Hong Kong graduates have traditionally relied on is undergoing visible change,” Shah noted. “We are seeing a clear 55% reduction in advertised graduate positions through the public university portals, and AI is already handling many of the basic starter tasks that used to be managed by new hires. Current trends suggest this shift will continue in the coming years.”

Current data indicates ongoing change in the market

Hong Kong’s graduate recruitment environment is showing clear movement:

  • Full-time graduate vacancies through the eight public universities declined approximately 55% year-on-year in the most recent reporting period — the lowest figure in five years.
  • Generative AI is now commonly used for functions previously assigned to new graduates: basic email drafting, data entry, customer-service responses, simple translation, content generation, junior administrative support, and routine compliance monitoring.
  • Surveys of employers from late 2025 into early 2026 show many companies planning continued adjustments to graduate intake, with AI often identified as an alternative for repetitive entry-level work.

Shah points to the 55% drop as evidence of a broader structural shift, supported by international workforce analyses (McKinsey, Goldman Sachs, IMF 2023–2025) that expect continued automation in administrative, clerical, and service-oriented sectors. “When AI reliably performs 70–80% of a junior role’s output at significantly lower cost, the economic rationale for retaining the human equivalent becomes more challenging,” he explained. “Across many Hong Kong businesses, this reasoning is contributing to the changes we observe in traditional graduate entry opportunities.”

A changing job market structure

Shah highlighted an important distinction:

  • Overall employment levels in Hong Kong are not expected to decline sharply. New roles will continue to emerge.
  • Emerging demand is increasingly focused on positions that require immediate AI fluency combined with specialised human judgment — a combination that most current graduates are not yet fully prepared to meet from day one.

“The graduate entry market is shifting noticeably,” Shah observed. “Premium opportunities now often require AI proficiency from the outset. The large volume of ‘learn-as-you-go’ starter positions that historically served as the bridge is contracting. The middle ground is narrowing.”

This observation comes as Hong Kong experiences a pronounced contraction in graduate employment in recent years, with ongoing youth unemployment pressures and companies placing greater emphasis on AI solutions for routine functions.

(The 55% figure reflects reported year-on-year vacancy data from Hong Kong’s public university job portals. Future developments will depend on upskilling initiatives, economic conditions, and policy responses. The observed direction is consistent with current trends and international analyses.)
