# Where to Go Next Completing the Mastering Bitcoin pathway gives you a strong conceptual understanding of how the Bitcoin protocol works. Many learners choose to continue by building practical skills, exploring open-source projects, or contributing to the Bitcoin ecosystem. Below are a few common next steps. *** ### Build Practical Bitcoin Core Skills If you want to move from theory into hands-on interaction with Bitcoin software, consider studying: [**Learn Bitcoin from the Command Line**](https://pathways.btrust.tech/02) This pathway focuses on practical interaction with Bitcoin Core using bitcoin-cli, including: * Running and inspecting a node * Constructing transactions * Working with multisig and PSBTs * Exploring Bitcoin Script It is one of the most effective ways to build operational familiarity with Bitcoin’s core software. *** ### Start Exploring Bitcoin Development If you’re interested in writing code for Bitcoin-related software, the next step is to begin exploring development tools and environments. You can start by: * Running a local Bitcoin development environment * Reading Bitcoin Core documentation * Exploring open-source repositories * Reviewing issues and discussions in Bitcoin developer communities Many learners begin by understanding how Bitcoin Core itself is structured. *** ### Study a Bitcoin Development Language Many Bitcoin developers work in languages such as: * Rust * C++ * Python * JavaScript Builders pathways such as [**Rust for Bitcoiners**](https://pathways.btrust.tech/03) and [**Language Clubs**](https://pathways.btrust.tech/04) are designed to help developers begin building tools, libraries, and infrastructure around Bitcoin. *** ### Explore the Builders Resource Hub The Builders [Resource Hub](https://pathways.btrust.tech/resource-hub) contains curated resources for developers entering the Bitcoin ecosystem. This includes: * Guides for making your first open-source contribution * Developer tools and setup walkthroughs * Curated Bitcoin open-source projects * Code review and collaboration practices Many learners use the Hub as their starting point for contributing to Bitcoin open source. *** ### Join the Builders Community Learning Bitcoin development works best when you connect with others doing the same work. In the Builders community you can: * Discuss technical concepts * Ask questions about development workflows * Discover open-source opportunities * Share your learning progress Many contributors begin simply by participating in discussions and helping others understand concepts.
