Introduction
Blockchain technology has seen exponential growth in patent filings—from just 23 applications in 2015 to nearly 700 by 2017 in China alone. While developers naturally seek legal safeguards, the monopolistic nature of patents appears to clash with blockchain’s foundational principles of decentralization and shared access.
Under existing intellectual property (IP) frameworks, blockchain innovations can secure protection via patents, copyrights, trade secrets, and contractual agreements. Yet, as a disruptive technology, does traditional IP protection hinder its progress? Could open-source models offer a more aligned approach?
This article explores:
– Conventional IP protections for blockchain (copyrights, patents, trade secrets).
– The synergy between open-source licensing and IP rights.
– Why blockchain’s ethos may thrive best under open-source paradigms.

1. Traditional IP Protections for Blockchain Technology
1.1 Copyright Protection for Software
Under the Copyright Law and Computer Software Protection Regulations, blockchain’s source code automatically qualifies for copyright upon creation. Key protections include:
– Exclusive rights: Reproduction, distribution, modification, and public display.
– User limitations: Legally, users may only install, copy for personal use, or modify software privately. Unauthorized actions risk infringement claims.
Example: A developer copying Bitcoin’s codebase without permission could face litigation, even if they alter parts of the code.
1.2 Patent Protection: A Double-Edged Sword
Patents guard technical concepts, not just code implementations. This broader scope lets patent holders block competitors using similar methods—even with independently written code.
Challenges:
– Patent eligibility: Many jurisdictions reject software patents as “abstract ideas” (e.g., U.S. post-Alice). However, China’s guidelines allow patents if the software solves a “technical problem” (e.g., optimizing blockchain consensus mechanisms).
– Patent trolling: Entities like Craig Wright’s EITC have filed hundreds of blockchain patents, threatening open innovation.
Case Study: The Bitcoin white paper’s open-source release preempted patents on core algorithms (e.g., SHA-256), preserving community access.

1.3 Trade Secrets and Contractual Safeguards
Trade secrets apply when:
– Source code remains confidential.
– Developers enforce NDAs or End-User License Agreements (EULAs) to restrict reverse engineering.
Risks: Leaked code nullifies secrecy, leaving only copyright/contract claims.
2. Open-Source Software: A Collaborative Alternative
2.1 How Open-Source Licensing Works
Contrary to myths, open-source ≠ surrendering IP rights. Key principles:
– Retained copyright: Developers license usage under terms like GPL or MIT.
– Patent clauses: Many licenses grant users implicit patent rights (e.g., Apache 2.0).
Example: Linux’s success stems from its GPL license, requiring derivative works to also open-source their code.
2.2 Copyleft vs. Permissive Licenses
| License Type | Key Requirement | Example |
|---|---|---|
| Copyleft (GPL) | Derivatives must be open-sourced | Bitcoin Core |
| Permissive (MIT) | No such obligation | Ethereum Solidity |
Blockchain Fit: Projects like Hyperledger use permissive licenses to encourage enterprise adoption.
3. Why Blockchain Thrives with Open-Source
3.1 Trust Through Transparency
Open code lets users verify security claims—critical for decentralized systems like Ethereum.
3.2 Accelerating Innovation
- Collaboration: Developers build atop existing projects (e.g., forks of Bitcoin).
- Avoiding lock-in: Proprietary blockchains risk fragmenting the ecosystem.
3.3 Aligning with Decentralization
IP laws rely on centralized authorities (e.g., patent offices). Open-source models empower community-driven governance, mirroring blockchain’s ethos.
FAQs
Q1: Can open-source software be patented?
A: Yes—but licenses like GPLv3 require patent holders to grant universal usage rights.
Q2: Does copyright protect blockchain’s underlying algorithms?
A: No. Copyright covers code expression, not functional concepts (e.g., proof-of-work).
Q3: How do trade secrets apply to public blockchains?
A: They don’t. Once code is on-chain, it’s inherently public.
Q4: What’s the risk of not using an open-source license?
A: Unlicensed code defaults to “all rights reserved,” deterring reuse.
Conclusion
Blockchain’s future hinges on balancing IP protection with open collaboration. While patents offer defensive tools, open-source models may better sustain its decentralized vision. For developers, the choice hinges on goals:
– Control: Patent key innovations.
– Adoption: Open-source to foster ecosystem growth.
