Blockchain technology has experienced explosive growth in recent years, not only in application but also in legal and intellectual property (IP) considerations. From 23 patent applications in China in 2015 to nearly 700 in 2017, the race to secure IP rights around blockchain is intensifying. Yet, this surge in patenting raises a fundamental question: does traditional IP protection align with the decentralized, collaborative spirit of blockchain—or is open source a more suitable path forward?
This article explores how blockchain developers can leverage existing intellectual property frameworks—copyright, patents, and trade secrets—while also examining the powerful synergy between blockchain and open-source principles. We’ll analyze whether open source isn’t just compatible with blockchain, but perhaps its most authentic form of protection.
Traditional Intellectual Property Protection for Blockchain Technology
Software Copyright Protection
At its core, blockchain is software—and software is automatically protected under copyright law the moment it’s created. In jurisdictions like China, the Copyright Law and the Regulations on the Protection of Computer Software grant creators exclusive rights including reproduction, distribution, modification, and public dissemination.
However, user rights are limited. Under Chinese regulations, users may only install, copy for personal use, or modify software privately. Any unauthorized replication or derivation could constitute copyright infringement.
For blockchain developers, this means their source code enjoys strong legal backing. But here’s the catch: copyright protects only the expression of an idea (i.e., the actual code), not the underlying concepts or algorithms. So while someone can’t copy your code verbatim, they can rewrite the same functionality using different syntax—and remain within legal bounds.

Patent Protection for Blockchain Innovations
Patents go further than copyright by protecting the idea behind the technology—specifically, technical solutions to real-world problems. A patented blockchain mechanism, such as a novel consensus algorithm or data validation process, can block competitors even if they write entirely new code.
Historically, software-related inventions faced hurdles due to being classified as "mental activities" or mathematical methods—categories excluded from patentability under Article 25 of China’s Patent Law. However, the 2010 Patent Examination Guidelines clarified that software can be patented if it solves a technical problem using technical means and produces a technical effect.
This opened the floodgates. Major tech and financial firms have since filed hundreds of blockchain-related patents globally. Even Craig Wright, who claims to be Bitcoin’s creator Satoshi Nakamoto, has used his company EITC to file dozens of foundational blockchain patents.
Still, core technologies like hashing, asymmetric encryption, and peer-to-peer networking are already in the public domain. This limits the ability of any single entity to monopolize blockchain’s foundations. Nevertheless, the “land grab” for peripheral innovations continues.
Trade Secret Protection
Unlike open-source projects, proprietary blockchain platforms often rely on trade secret law. To qualify, information must be secret, have commercial value, and be subject to reasonable confidentiality measures.
Source code kept private and distributed under restrictive end-user license agreements (EULAs) often meets these criteria. Breaching such terms may lead to claims of copyright infringement, trade secret theft, or contractual violation.
While this model maximizes control and profit potential, it contradicts blockchain’s ethos of transparency and decentralization. Users are asked to trust opaque systems—ironic for a technology designed to eliminate intermediaries.
The Rise of Open Source in Software Development
The open-source movement emerged as a response to overreaching IP protection. Contrary to popular belief, open source does not mean giving up intellectual property. Instead, it uses copyright as a tool to enforce sharing.
Developers retain ownership but grant broad usage rights through open-source licenses. These licenses specify conditions—such as attribution requirements or obligations to share derivative works (as in copyleft licenses like GPL).
By preserving copyright while promoting collaboration, open source strikes a balance between protection and progress. Many open-source licenses also include implicit patent grants, ensuring contributors cannot later sue users for patent infringement.
This model empowers innovation: developers build on each other’s work without fear of litigation, accelerating technological advancement.

Why Open Source Aligns with Blockchain’s Core Values
Blockchain was born in an open-source environment—Bitcoin’s code was published freely from day one. This wasn’t accidental; it reflects deep philosophical alignment.
1. Open Source Builds Trust
The Economist famously called blockchain “the machine for creating trust.” But trust requires transparency. When code is closed, users must blindly accept that it functions as advertised. With open source, anyone can inspect, audit, and verify the system.
This transparency reinforces confidence in smart contracts, consensus mechanisms, and token economics—critical for adoption in finance, healthcare, and governance.
2. Open Source Accelerates Innovation
Blockchain’s potential spans industries: supply chain tracking, digital identity, decentralized finance (DeFi), and more. Open-sourcing core protocols allows developers worldwide to experiment, improve, and integrate.
Ethereum’s success is a prime example: by being open source, it enabled thousands of projects to launch on its foundation—fueling an entire ecosystem.
3. Open Source Upholds Decentralization
Blockchain aims to remove centralized authorities. Yet relying on traditional IP systems—managed by national offices and enforced through courts—introduces central points of control.
Open source reduces dependency on these institutions. It enables community-driven development and governance, staying true to blockchain’s decentralized vision.
Moreover, blockchain itself can enhance IP protection—by providing immutable records for copyright registration or patent timestamps—closing the loop between technology and legal innovation.
Frequently Asked Questions
Q: Can you patent blockchain technology?
A: Yes, if it solves a technical problem with measurable effects. Abstract ideas or pure business methods are unlikely to qualify.
Q: Does open source mean no intellectual property protection?
A: No. Open source relies on copyright to enforce license terms. Developers retain ownership while granting usage rights.
Q: Can you use open-source blockchain code commercially?
A: Usually yes—but check the license. Permissive licenses (e.g., MIT) allow broad use; copyleft licenses (e.g., GPL) may require derivative works to also be open source.
Q: Is it risky to build on open-source blockchain platforms?
A: Risks exist—especially around license compliance—but they’re often outweighed by faster development and community support.
Q: Can you lose patent rights by open-sourcing your code?
A: Not necessarily. Some licenses include patent grants, but filing a patent before disclosure preserves your rights.
Q: Which is better: patents or open source for blockchain?
A: It depends on goals. Patents offer exclusivity; open source fosters trust and innovation. For public blockchains, open source is often more aligned with long-term success.

Conclusion
Blockchain stands at a crossroads: protect through exclusivity or empower through openness? While traditional IP tools like copyright, patents, and trade secrets offer legal safeguards, they risk undermining the very principles that make blockchain revolutionary.
Open source doesn’t abandon protection—it redefines it. By leveraging copyright to mandate sharing rather than restrict it, open source supports transparency, innovation, and decentralization.
For blockchain—the “trust machine”—openness isn’t just idealistic; it’s essential. The future of blockchain may not be owned by any single entity, but built collectively by a global community committed to shared progress.
