Blockchain technology has emerged as a transformative force in digital innovation, capturing global attention for its decentralized, secure, and transparent architecture. In China, the government’s strategic emphasis on blockchain as a core technological breakthrough—highlighted by President Xi Jinping’s 2019 directive—has accelerated both industrial adoption and legal scrutiny. As blockchain applications expand beyond cryptocurrencies into areas like digital evidence, intellectual property, and enterprise services, courts across China have begun shaping a nuanced jurisprudence around this evolving technology.
This article explores the current state of blockchain-related legal practice through an analysis of over 500 judicial cases up to 2020, focusing on three key dimensions: cryptocurrency disputes, blockchain-based digital evidence, and regulatory compliance under the Blockchain Information Service Management Regulations. By examining landmark rulings and emerging trends, we aim to provide a comprehensive understanding of how Chinese law interprets and governs blockchain innovations.
Cryptocurrency Disputes: Property Rights and Contract Enforcement
Despite official restrictions on cryptocurrency circulation, Chinese courts have consistently recognized digital assets like Bitcoin and Ethereum as legally protectable property. Two pivotal cases illustrate this evolving stance.
Unjust Enrichment and the Legal Status of Virtual Currencies
In Beijing XFB Technology Co., Ltd. v. Chen, the Shanghai Hongkou District Court ruled that Ethereum (ETH) qualifies as a legitimate asset under civil law, even though it lacks legal tender status. The case involved a mistaken transfer of 20 ETH due to operational error. The court held that the recipient’s refusal to return the funds constituted unjust enrichment, emphasizing that while virtual currencies are prohibited from monetary use, they remain subject to property protection principles. This decision affirms that blockchain assets can be objects of civil rights, provided their handling does not involve illegal financial activities.
Contractual Obligations in Cryptocurrency Platforms
The Feng v. Beijing LKD Company case further clarified user rights in platform-generated obligations. When LKD failed to distribute Bitcoin Cash (BCC) following a network fork, despite prior public commitments, the Beijing courts found the company bound by contract law. The ruling established that platform announcements constitute binding contractual terms when users rely on them for investment decisions. While the court rejected claims for market-value losses—citing unpredictability of price fluctuations—it upheld the obligation to deliver the forked coins, reinforcing the enforceability of blockchain-related service agreements.
These cases collectively affirm that although China prohibits cryptocurrency trading and financing activities, holders retain enforceable civil rights over their digital assets. Courts distinguish between speculative financial use—which is restricted—and ownership and contractual entitlements—which are protected.

Blockchain Evidence: Revolutionizing Digital Forensics
One of the most impactful legal applications of blockchain lies in electronic evidence preservation. With traditional notarization being costly and time-consuming, blockchain-powered tools like timestamping and decentralized storage offer efficient alternatives for proving authenticity.
Landmark Ruling: Blockchain-Verified Copyright Infringement
In Hangzhou HTY Company v. Shenzhen DT Company, the Hangzhou Internet Court delivered China’s first judgment based on blockchain-stored evidence. The plaintiff used a third-party platform called Baoquan.com to capture and store screenshots of infringing content on a defendant’s website. The data was hashed and recorded on both Factom and Bitcoin blockchains, ensuring immutability.
The court evaluated the evidence using four criteria:
- Source reliability: The platform operated independently from either party.
- Technical integrity: Open-source tools (Puppeteer and cURL) were used for automated capture.
- Data consistency: Hash values matched before and after storage.
- Chain verification: Cross-referencing across multiple blockchains confirmed unaltered records.
The ruling set a precedent: blockchain-stored data meets legal standards for authenticity if the system ensures traceability, transparency, and resistance to tampering.
When Blockchain Evidence Fails: The Importance of Procedure
Conversely, in Beijing YT Company v. Shanghai DFW Company, the court rejected blockchain-backed claims due to procedural flaws. Although the plaintiff used time-stamping technology, it failed to verify internet connectivity or DNS settings during capture—a critical step outlined in official guidelines. Without confirming the legitimacy of the browsing environment, the evidence could not rule out fabricated links or spoofed websites.
This outcome underscores a crucial principle: technology alone does not guarantee admissibility. Even advanced systems like blockchain require strict procedural compliance to meet evidentiary thresholds.

Regulatory Framework: Navigating Compliance Under Chinese Law
China’s Blockchain Information Service Management Regulations, effective since February 2019, represent the country’s first comprehensive regulatory framework for blockchain operators.
Core Requirements for Service Providers
Under Article 5, providers must implement content moderation mechanisms, including:
- Real-name user registration
- Pre-screening of published information
- Emergency response protocols for illegal content
- Technical safeguards aligned with national cybersecurity standards
Additionally, Article 11 mandates registration with the Cyberspace Administration of China (CAC), requiring disclosure of entity details, technical infrastructure, and security measures. Failure to comply may result in service suspension or fines.
Trademark Law and Misleading Claims
The case of YXHL Co., Ltd. v. National Intellectual Property Administration highlights risks in branding. YXHL sought to register “Youxin Blockchain” for tech services but was denied on grounds of potential consumer deception—since the company had not yet implemented actual blockchain solutions. The Beijing Higher People’s Court ruled that using “blockchain” in a trademark may mislead the public about service capabilities, violating Article 10(7) of the Trademark Law.
This signals a broader trend: regulators scrutinize whether companies substantiate technological claims. Firms must align marketing with actual technical deployment to avoid legal challenges.
Frequently Asked Questions (FAQs)
Q: Are cryptocurrencies legal in China?
A: While trading and issuance of cryptocurrencies are banned, private ownership is not criminalized. Courts recognize them as property in civil disputes involving contracts or unjust enrichment.
Q: Can blockchain evidence be used in court?
A: Yes. Chinese internet courts accept blockchain-verified data if it demonstrates source reliability, procedural integrity, and tamper-proof storage across trusted networks.
Q: Do individuals need to register under the Blockchain Regulations?
A: The rules primarily target organizations providing public blockchain services. Individual developers or non-commercial users are generally exempt unless operating as service providers.
Q: What happens if a company uses “blockchain” in its name without real implementation?
A: It may face trademark rejection or administrative penalties for misleading claims, as seen in the YXHL case.
Q: How do courts assess the validity of smart contracts?
A: While not yet widely litigated, existing rulings suggest that automated agreements are treated as standard contracts if terms are clear and consent is verifiable.
Q: Is cross-border blockchain data transfer permitted?
A: Subject to China’s data localization laws, especially for personal information. Companies must ensure compliance with the Cybersecurity Law and Data Security Law when transmitting data abroad.

Conclusion
As blockchain transitions from experimental technology to mainstream application, its intersection with law becomes increasingly complex. Chinese jurisprudence reflects a balanced approach—restricting speculative finance while protecting legitimate property rights and embracing innovative evidence methods. For businesses and developers, success hinges on understanding not only technical capabilities but also legal boundaries.
From unjust enrichment claims involving ETH to trademark disputes over "blockchain" branding, judicial outcomes reveal a system adapting to digital realities. The takeaway is clear: transparency, procedural rigor, and regulatory compliance are essential for sustainable innovation in China’s rapidly evolving blockchain landscape.
