One of the many topics of discussion in the Bitcoin community today is which client users should choose: Bitcoin Core or Bitcoin XT? The debate is expected to be settled early next year. However, rarely mentioned in these discussions are the viable alternative clients based on different programming languages — despite there being a fair number to choose from. Does the Bitcoin ecosystem need more clients written in multiple languages, or is the current situation sufficient?
A Plethora of Bitcoin Wallets or Centralized Options?
Bitcoin Core and Bitcoin XT are the two most popular desktop software clients (though XT remains controversial). Many users forget that several other options exist, most of which serve as light clients — a preference for many. In truth, both major clients support virtually every operating system: Windows, Linux, macOS, and even mobile. But the question remains: are consumer choices too limited?
Let’s be clear: this is not a call for more forks of the Bitcoin protocol to create additional wallets. The point is that today’s Bitcoin wallets are written in a single programming language. What if a developer wants to contribute but is not comfortable with that language? One of Bitcoin’s beautiful aspects — and the blockchain technology that powers it — is that developers can interact with the network using any language: Ruby, Java, C++, Python, or others. Interfacing with the blockchain is straightforward.
Yet contributing to Bitcoin Core or XT is restricted to one codebase. While it is possible to convert code from one language to another, the process is time-consuming and complex. A solution might be simpler than it seems. Bitcoin can take a page from Ethereum, which offers multiple clients written in different languages. In fact, Ethereum’s core developers encourage alternative wallets to support every major coding language.
The Benefits of Supporting Multiple Coding Languages
Creating duplicate versions of Bitcoin Core and XT to support all major languages may seem daunting, but the benefits are clear. Perhaps the biggest advantage is that multiple teams of developers can bring improvements to the table. Once enhancements are made in one version, they can be adapted by others — provided the groups coordinate well to avoid issues.
Moreover, more people would have the chance to experiment with Bitcoin client code, which can only benefit the overall development of this disruptive digital currency. Proposed changes may or may not be adopted by other versions unless consensus is reached.
