The Untangling of Bitcoin’s Code: Introducing Libbitcoinkernel
“Libbitcoinkernel” is an ongoing project that aims to simplify Bitcoin’s code, making it easier for developers to experiment with changes and improvements to the cryptocurrency. The goal is to separate the “security-critical” code from the rest of Bitcoin Core’s code, allowing developers to focus on specific areas without risking unintended consequences. By untangling the code, developers can more quickly introduce new features and enhancements that will eventually benefit users as well.
Initially spearheaded by Bitcoin developer Carl Dong, Libbitcoinkernel has now been taken over by Sebastian Kung, Cory Fields, and other members of the community. They believe that this project could have a significant impact on the Bitcoin ecosystem.
Avoiding a ‘Nightmare Scenario’
The consensus code in Bitcoin Core ensures that all nodes in the network agree with each other. However, this code is intertwined with the rest of Bitcoin Core’s code, making it challenging for developers to make changes without potentially causing a network split or “hard fork.” The aim of Libbitcoinkernel is to extract the consensus code into a separate library so that developers can work on other areas without worrying about unintentional disruptions. This allows for more focused review and discussion of the critical consensus code.
The ‘Flashy’ Goal: Multiple Bitcoin Clients
Another long-term goal of Libbitcoinkernel is to enable multiple implementations of Bitcoin’s code. Currently, Bitcoin Core is the main implementation used by users. Having alternative implementations would allow developers to experiment with new features and prioritize different aspects based on their target users. It would also increase the network’s resilience and decentralization. However, without separating the consensus code, implementing alternative clients was considered risky due to potential incompatibilities. Libbitcoinkernel addresses this concern by providing a reusable consensus library.
Learning from Abandoned Attempts
The idea of extracting the consensus code from Bitcoin Core has been explored in the past but was left unfinished. Previous attempts faced challenges due to the project’s complexity. The developers of Libbitcoinkernel are taking an iterative approach and recognize that it will be a long-term endeavor. They have made significant progress but expect the project to span multiple release cycles. The development can be tracked on GitHub, where developers have contributed numerous proposed changes.
Hot Take: A Promising Future for Bitcoin Development
Libbitcoinkernel has the potential to revolutionize Bitcoin development by untangling its code and enabling faster innovation. By separating the security-critical code and creating a reusable consensus library, developers can focus on enhancing Bitcoin’s privacy, security, and user experience. This project not only benefits developers but also has wider implications for Bitcoin users and the overall decentralization of the network. As Libbitcoinkernel progresses, we can expect to see exciting new features and improvements that will shape the future of Bitcoin.
