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.

By

San Francisco, California –  3 July 2025

Zypher Network, a decentralized trust infrastructure provider for autonomous AI agents, announced close of a $7 million funding round to accelerate the development of its zero-knowledge (ZK) protocol stack and AI-specific rollup infrastructure. The round was co-led by UOB Venture and Signum Capital, with participation from HashKey Capital, Hong Leong Group, Cogitent Ventures, Catcher VC, Hydrogenesis Labs, DWF Venture, and other strategic investors.

As large language model (LLM)-based autonomous agents gain momentum through platforms such as Nvidia Eureka and OpenAI Operator, the market for agent-driven ecosystems is projected to reach $250–350 billion by 2035, with transformative potential across the broader $10 trillion “as-a-service” sector. This shift has heightened the urgency for standardized, verifiable mechanisms to ensure trust, reliability, and accountability in AI agent behavior—paralleling the historical rise of SSL as a foundational security layer for the internet.

Zypher Network addresses this need through its open-source, zero-knowledge protocol suite, designed to certify agent integrity, transparency, and data privacy. Its flagship product, Proof of Prompt, is a zkTLS-inspired protocol that enables public verification of system prompts without revealing sensitive inputs or outputs. The solution is delivered via a RESTful API, making it accessible to developers and enterprises integrating agent-based automation across domains such as legal operations, customer support, robotics, and financial services. For end-users, Zypher also offers an AI security browser, enabling real-time detection of potentially malicious agentic behavior.

The API layer is powered by Zytron, Zypher’s dedicated AI rollup infrastructure, whose first production instance operates as a Layer 2 on BNB Chain, compatible with RISC-V architecture. Zytron also supports Proof Mining, a decentralized prover system based on Proof of Verifiable Work, facilitating scalable, distributed ZK proof computation and verification.

“We are excited about Zypher’s “proof of prompts” distributed solution and the committed team behind.  We foresee Zytron will be an important building block to embed trust in the AI applications out there.” – YY, Managing Partner, Signum Capital

The newly raised capital will be allocated toward team expansion, infrastructure scaling, and the launch of incentive-driven initiatives aimed at broadening Zypher’s developer and user ecosystem. To date, Zypher has engaged over one million on-chain participants through its community campaigns and ecosystem programs. Its trust layer is integrated with a wide array of leading protocols—including Eliza OS, io.Net, Nexus, Risc Zero, Eigen Layer, Particle Network, Fermah, Polyhedra, and ZeroBase—enhancing interoperability and improving the developer experience.

In the coming months, Zypher will roll out a large-scale Social & Proof Mining campaign designed to incentivize decentralized agent verification, with early participation from key agent partners across its network.

“Our trust layer protocol is redefining what’s possible in agent verification. With this funding, we’re accelerating the rollout of scalable ZK infrastructure that ensures trust without sacrificing privacy. We’re proud to be building this with our incredible ecosystem partners, each playing a critical role in shaping a more transparent, verifiable future for AI.” – Giv Zypher CEO
