From Blockchain to Programming: An All-Encompassing Explanation of the Fork Concept

Why is a fork so important?

The concept of “fork” is ubiquitous in the tech world. Whether you’re a trader, developer, or ordinary tech user, you may encounter various forms of forks. This term, derived from the English “fork” (a fork or branching point), seems simple but actually represents a powerful innovation mechanism—creating an independent new direction based on an existing foundation. Understanding forks is crucial for grasping the modern technological ecosystem.

The essence of a fork: splitting, copying, and rebirth

In technology, a fork refers to a “separation” based on an established foundation—be it source code, blockchain protocol, or application framework. The resulting entity is not just a simple copy but a new independent entity capable of evolving on its own.

Originally, the concept of a fork appeared in open-source programming communities and later permeated into cryptocurrency, operating systems, and even security fields. Although the application scenarios differ, the core principle remains consistent: obtain the original resource, modify it according to new goals and ideas, and let this modified version exist and develop independently.

Forks in the cryptocurrency world: the collision of technology and ideology

Blockchain networks rely on all participants (nodes, miners, users) following the same rules. When these rules change, the network may split.

Hard fork vs. soft fork: two different evolution paths

Hard fork signifies an irreversible update to the rules. Nodes running the old version cannot communicate with those running the new version, ultimately resulting in the blockchain splitting into two separate chains. This often creates a new crypto asset.

In 2017, the Bitcoin community experienced intense debate over transaction speed issues. The supporting team decided to increase the block size from 1MB to 8MB, leading to the creation of Bitcoin Cash (BCH)—now an independent crypto asset, priced at $630.65, with a 24-hour increase of +1.05%, and a market cap of $12.60B.

The Ethereum incident in 2016 was even more dramatic. A hacker attack caused The DAO project to lose a large amount of funds. To recover the funds, the community decided to rewrite the transaction history—violating the principle of “code is law.” Supporters created Ethereum Classic (ETC), advocating for absolute immutability of the blockchain. Today, ETC trades at $12.69, up +2.15%, with a market cap of $1.97B. This split became a permanent testament to ideological differences.

Bitcoin SV (BSV) has a more complex story. It is a hard fork of Bitcoin Cash, created when developers attempted to further increase the block size to 128MB. Different technical visions led to a third split. Currently, BSV is priced at $19.43, with a 24-hour increase of +0.67%.

Soft fork is relatively milder. It maintains backward compatibility; nodes that haven’t updated can still participate in the network, but with limited functionality. Bitcoin’s SegWit upgrade in 2017 is an example, optimizing transaction structure without splitting the network.

Impact of forks that traders need to understand

When a hard fork occurs, users holding the original coin usually receive an equivalent amount of the new coin. For example, Bitcoin holders automatically received Bitcoin Cash during the BCH fork. This adds value to their portfolio but also involves price fluctuation risks. Currently, Bitcoin trades at $90,680, with a 24-hour increase of +0.74%, and a market cap of $1,811.14B. Ethereum is priced at $3.10K, up +0.07%, with a market cap of $374.10B.

Forks in the programming world: engines of collaboration and innovation

On code hosting platforms like GitHub and GitLab, forks are the cornerstone of the open-source ecosystem. They allow developers to freely modify and improve code without needing write access to the original project.

From copying to contribution workflow

Creating a fork is very simple: go to the project page, click the Fork button, and the system will create a complete copy under your account. Then you can:

• freely experiment and modify
• clone the copy locally for development
• submit improvements via Pull Request for review

This process has fostered some of the most vibrant open-source projects worldwide.

fork vs. clone: same name, different entity

Many people confuse these two concepts. A fork is a server-side operation—it creates a cloud-based copy that is completely independent. Cloning is a local operation—downloading code from the cloud to your local machine. Typically, you fork a project to your GitHub account first, then clone it to your computer for work.

Examples of OS and application evolution

The Linux ecosystem is full of successful fork examples. Ubuntu, based on Debian, optimized user experience, while Linux Mint derived from Ubuntu added a unique desktop environment. These forks demonstrate how a single foundation can evolve into multiple versions meeting different needs.

In application development, Brave browser is a successful fork of Chromium. It retains Chrome’s core but adds innovative features like privacy protection, ad blocking, and integrated encrypted payment systems. This case proves that a fork is not just technical copying but also value reshaping.

Unnoticed applications of forks

Media ecosystem on Smart TVs

Applications like ForkPlayer are essentially modifications of standard media players, enabling convenient online content aggregation through forks. They demonstrate practical applications of forks in consumer devices.

The dark side of system security

“Fork bomb” is a malicious program that infinitely generates new processes, eventually exhausting system resources and causing a crash. It exploits the process forking mechanism of operating systems. Defense methods include setting process limits (using ulimit in Linux) and avoiding executing untrusted scripts.

Localization of terminology in Russian

In the tech community, “форкнуть” (verb form) has become an idiomatic expression. Although it originates from English, it has been fully integrated into Russian technical terminology.

In formal documentation, more neutral expressions like “создать форк,” “произвести форк,” or “разделить сеть” are preferred. The choice depends on your audience and context—on technical forums, “форкнуть” is acceptable, but in corporate reports, more formal wording is recommended.

Synonyms should match the specific context:

• In programming: ответвление (branch), копия (copy)
• In cryptocurrency: раскол (split), обновление (upgrade)
• In application development: модификация (modification)

Summary points

As a widespread technical mechanism, forks drive innovation across various fields:

• In cryptocurrency, hard forks create new assets (Bitcoin Cash, Ethereum Classic), while soft forks optimize existing networks. Traders need to understand how splits affect prices and holdings.
• In programming, forks are the foundation of open-source collaboration, enabling developers worldwide to contribute and produce excellent projects like Ubuntu and Brave.
• At the application level, forks embody technological democratization—anyone can access basic tools and innovate according to their ideals.

Whether you’re trading crypto assets on an exchange or submitting pull requests in a code repository, forks play a role in empowerment and innovation. Mastering this concept helps you better understand the operation of the modern tech ecosystem.
