Bitcoin Core

Bitcoin Core is open-source C++ software that connects to the Bitcoin peer-to-peer network, downloads and fully validates blocks and transactions, and can optionally provide wallet and graphical user interface functionality.

Understand the project

Practical overview

When it fits

Use Bitcoin Core when a project needs direct Bitcoin network connectivity and local block or transaction validation, or when its wallet and graphical interface functionality can serve as a foundation.

Who it is for

  • Bitcoin node operators
  • Developers building Bitcoin wallets, desktop clients or monitoring tools
  • Technically oriented users working with peer-to-peer networking, validation or cryptography

Documented uses

  • Run a Bitcoin peer-to-peer node.
  • Download and validate Bitcoin blocks and transactions.
  • Build a wallet application using Bitcoin Core wallet functionality.
  • Create a desktop Bitcoin client with an optional graphical interface.
  • Develop monitoring or validation tools around a local node.
Before you choose

Requirements & limits

The public GitHub repository is accessible, active and not archived. It is released under the MIT license and supports Windows, Linux, macOS, command-line and desktop use.

  • Whether the task requires a local node that downloads and fully validates Bitcoin data
  • Whether wallet functionality or an optional graphical interface is needed
  • Whether C++ and Bitcoin peer-to-peer, validation or cryptography concepts fit the development workflow
  • Whether command-line or desktop operation is more suitable

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Build Bitcoin Core and run its documented automated tests

Build Bitcoin Core from the repository and run the documented unit and functional test commands.

Before you start

  • A checkout of the Bitcoin Core repository.
  • Build instructions from the repository's doc/build-*.md files.
  • Required test dependencies for the functional tests.

Steps

  1. Use the build instructions in doc/build-*.md to generate a build.

  2. Run ctest for the unit tests, provided they were not disabled during build-system generation.

  3. Run build/test/functional/test_runner.py for the regression and integration tests, assuming the required test dependencies are installed.

  4. Apply the project's documented testing and review practices before treating changes as ready.

Expected outcome

Bitcoin Core is built, and the documented automated test suites can be run against the build.

Guide limitations

  • The master branch is regularly built and tested but is not guaranteed to be completely stable.
  • The functional test command assumes build is the build directory and that test dependencies are installed.
  • The source does not document platform-specific build commands or a successful test result.
  • The project describes testing and code review as a bottleneck and recommends testing changes by someone other than the developer.
