The global blockchain landscape is undergoing a pivotal transformation. As governments intensify scrutiny on energy-intensive cryptocurrency mining, the industry is being pushed toward a new era—one where blockchain technology shifts focus from speculative activities to tangible, real-world applications. This evolution is not just inevitable; it’s already underway.
China’s Nationwide Crackdown on Cryptocurrency Mining
In a decisive move aligning with national energy and environmental goals, Chinese authorities have systematically phased out cryptocurrency mining across multiple provinces. Following regulatory actions in Xinjiang, Inner Mongolia, Qinghai, and Yunnan, Sichuan—once a major hub for Bitcoin mining due to its abundant hydropower—officially joined the initiative.
On June 18, 2021, Sichuan’s relevant authorities issued a formal notice requiring power generation enterprises to conduct self-inspections and immediately cease supplying electricity to cryptocurrency mining operations. By June 19, the shutdown was in full effect.

This nationwide cleanup reflects a broader policy direction: prioritizing sustainable development and technological efficiency over high-energy, speculative digital asset production. While the short-term market sentiment dipped, industry experts view this not as a setback, but as a necessary recalibration.
From Mining to Meaningful Innovation
According to Wang Haifeng, Senior Researcher at OKLink Research Institute, the phase-out of proof-of-work (PoW) mining was anticipated within the industry, especially under the global push for carbon neutrality. "The consensus has long been that high-energy consumption models are unsustainable," he explains. "What we’re seeing now is not an end, but a transition toward more rational and responsible development."
The PoW mechanism, which underpins Bitcoin and requires massive computational power, is increasingly seen as outdated in the context of environmental sustainability. Its decline may accelerate the adoption of more energy-efficient consensus mechanisms like Proof-of-Stake (PoS) or hybrid models—ushering in a new phase of blockchain technological evolution.
But beyond technical upgrades, the most significant shift lies in refocusing blockchain’s purpose: from digital speculation to real economic value creation.
National Strategy: Blockchain as a Pillar of Digital Transformation
While mining operations face restrictions, China’s support for blockchain technology remains strong—and more targeted than ever. Since blockchain was elevated to a national strategic level, it has featured prominently in major policy frameworks:
- New Infrastructure ("New Infrastructure") initiatives
- The 14th Five-Year Plan
- Guidelines from the Ministry of Industry and Information Technology (MIIT) and Cyberspace Administration of China
In 2021, MIIT and the Cyberspace Administration jointly released Guiding Opinions on Accelerating Blockchain Technology Application and Industrial Development, setting a clear roadmap: by 2025, China aims to become a global leader in blockchain, with widespread adoption across key sectors.
This includes cultivating well-known blockchain-powered products in areas such as:
- Product traceability
- Data circulation
- Supply chain management
And establishing demonstrable, scenario-based applications that deliver measurable impact.
Blockchain’s Core: A Foundation for Trust and Efficiency
At its core, blockchain is more than just cryptocurrency. It is an integrated software system combining distributed networks, cryptographic security, smart contracts, and decentralized databases. As a next-generation information technology, it offers unparalleled advantages in transparency, immutability, and trustless collaboration.
Today, China has built a solid foundation for blockchain development. Real-world implementations are already delivering results in:
- Anti-counterfeiting and traceability: Ensuring authenticity in food, pharmaceuticals, and luxury goods.
- Supply chain management: Enhancing visibility and accountability across complex logistics networks.
- Judicial evidence storage: Securing tamper-proof digital records for legal proceedings.
- Government data sharing: Improving inter-agency coordination while protecting citizen privacy.
- Public services: Streamlining identity verification, welfare distribution, and urban management.
These use cases highlight blockchain’s potential to solve real problems—not just enable financial speculation.
OKLink: Pioneering Blockchain for Real-World Impact
As one of China’s earliest blockchain companies (founded in 2013), OKLink has evolved into a globally recognized leader in blockchain technology innovation. Far from being affected by the mining crackdown, the company has doubled down on building infrastructure that supports mainstream adoption.
OKLink’s R&D focus includes:
- Data layering technology – reducing data transmission costs and improving network scalability.
- Parallel multi-chain architecture – enabling faster development and deployment of decentralized applications (dApps).
Both technologies are independently developed and rank among the world’s most advanced in their field.
But technical prowess alone isn’t enough. OKLink understands that ecosystem development is critical to mass adoption.

To this end, the company has actively invested in:
- Industry capital funds supporting promising blockchain startups
- Grants and financing for foundational research projects
- Talent development programs nurturing the next generation of blockchain engineers
This holistic approach ensures that innovation isn’t limited to labs—it reaches markets, businesses, and communities.
The Road Ahead: A Multi-Application Era Is Near
Wang Haifeng remains optimistic about the future:
“History has repeatedly validated our path. With increasing national support and strategic clarity, blockchain technology will inevitably return to serving the real economy. At OKLink, we’re accelerating progress across on-chain security, industrial investment, talent cultivation, and core tech R&D. The era of diversified blockchain applications is closer than ever.”
Indeed, the phase-out of mining is not a signal of decline—it’s a catalyst for maturity. By removing energy-heavy distractions, regulators have created space for meaningful innovation to flourish.
Frequently Asked Questions (FAQ)
Q: Does banning cryptocurrency mining mean China is against blockchain?
A: No. The ban targets energy-intensive mining activities, not blockchain technology itself. China continues to promote blockchain for industrial and public service applications.
Q: What are some practical uses of blockchain beyond cryptocurrency?
A: Blockchain is used in supply chain tracking, digital identity verification, medical record sharing, intellectual property protection, voting systems, and secure government data exchange.
Q: How does blockchain contribute to carbon neutrality goals?
A: By replacing PoW with low-energy consensus mechanisms like PoS and optimizing data processing efficiency, blockchain can operate sustainably without massive electricity consumption.
Q: Is blockchain safe for enterprise use?
A: Yes. With features like encryption, decentralization, and immutable ledgers, blockchain enhances data integrity and reduces fraud risk—making it ideal for finance, healthcare, and logistics.
Q: Can small businesses benefit from blockchain?
A: Absolutely. Blockchain enables transparent supply chains, lowers transaction costs, improves customer trust through verifiable product origins, and opens access to decentralized finance (DeFi) tools.
Q: What role do companies like OKLink play in blockchain adoption?
A: They develop core infrastructure, fund innovation, train developers, and build tools that make blockchain accessible and scalable for real-world business needs.
