Open source code refers to software with publicly available code online, allowing anyone to view, access, and utilize it freely. Developers leverage existing open source code to build their software or propose changes and add new features. Source code itself is a set of instructions written by programmers in a computer language, defining how software functions.

In the crypto market, most blockchains and protocols are built on open source systems to ensure transparency and public verifiability. Projects often publish their code on GitHub, a leading platform for code storage and management.
Open source code is publicly available online and freely accessible.
Advantages of Open Source Software
The primary advantage of open source software lies in its accessibility and efficiency. As mentioned, anyone can view, modify, or use available code to develop their own software. This fosters:
- Collaboration and Knowledge Sharing: Developers can collectively review, contribute, and improve the code, identify and fix bugs promptly, leading to higher quality and more efficient software.
- Innovation and Creativity: Open source facilitates proposing new features or developing novel ideas based on existing code.
- Time and Resource Savings: Developers can save significant time and resources compared to building software from scratch.
Further benefits of using open source software include:
- Enhanced Security: Publicly available code allows for widespread scrutiny, enabling faster identification and resolution of security vulnerabilities.
- Customization Flexibility: Users can freely modify or extend functionalities to tailor the software to their specific needs.
- Cost-Effectiveness: Developed voluntarily and collaboratively, open source software often has lower costs than commercial alternatives, benefiting both developers and end-users.
- Transparency and Trust: Publicly accessible code allows users to understand how the software operates, fostering trust in the project.
Why Crypto Needs Open Source
Blockchain technology disrupted traditional finance and became the core of the crypto market. Leading blockchains like Bitcoin and Ethereum are open source.
Blockchain’s decentralized, public, and transparent nature aligns perfectly with the benefits of open source. Decentralization in blockchain means:
- No Central Authority: No single entity controls the network; instead, it’s operated and maintained by a distributed network of nodes.
- Publicly Shared Code: Anyone can propose modifications or additions to the blockchain’s operational code, subject to rigorous review and evaluation by experts.
Blockchain ensures decentralization, transparency, and public verifiability.
This eliminates centralized intermediaries (like banks) while building user trust. Open source blockchain platforms also encourage developers to utilize available resources to build decentralized applications (dApps) catering to diverse user needs.
For example, the Ethereum blockchain fosters a thriving DeFi ecosystem built on its smart contracts. Developers can use Ethereum’s open source software to create applications or their own blockchains, extracting value and generating revenue.
Open source is essential for building blockchains and their surrounding economies. The synergy between blockchain and open source is key to realizing the decentralized vision of Web3, minimizing reliance on intermediaries.
Open Source in Practice: Bitcoin and Ethereum
Open source pervades the crypto space. Let’s focus on its application in Bitcoin and Ethereum, the two largest blockchains.
Bitcoin and Open Source
On January 8, 2009, Satoshi Nakamoto released Bitcoin’s open source code (v0.1), marking open source’s first application in crypto. Bitcoin v0.1 is now known as Bitcoin Core.

As of October 25, 2023:
- Over 100 developers have contributed to Bitcoin Core (source: GitHub).
- Numerous open source applications are built on Bitcoin’s infrastructure, from wallets like Electrum and Phoenix to developer tools like the Bitcoin Dev Kit and Lightning Dev Kit.

Ethereum and Open Source
Ethereum’s blockchain has experienced significant growth with its vast DeFi ecosystem. It boasts the most active developer community:
- Over 3,000 dApps built on Ethereum’s open source code (source: DappRadar), encompassing games, decentralized exchanges (DEXs), wallets, NFTs, liquid staking, and lending platforms.
- Over 700 Ethereum Improvement Proposals (EIPs) tracked on their official website.
EIPs are crucial in determining how Ethereum modifies or adds new features for improved efficiency and user needs. After successful EIP implementation, projects can leverage the open source code to build their own software and applications. Notable EIPs and applications include:
- The popular Bored Ape Yacht Club NFT collection uses the ERC-721 token standard proposed in EIP-721.
- Smart contract wallets like Gnosis Multisig and ConsenSys Multisig utilize the ERC-4337 token standard from EIP-4337.
- The ERC-20 token standard is widely used for deploying fungible tokens on Ethereum.
In conclusion, open source is fundamental to the development and growth of the cryptocurrency ecosystem, fostering transparency, collaboration, and innovation. Its principles align perfectly with the decentralized ethos of blockchain technology, paving the way for a more open and accessible financial future.
