Flow Go

Flow Go is the open-source Go reference implementation of the Flow Layer 1 proof-of-stake blockchain. It provides the node software, consensus and distributed-systems components, and Cadence VM integration used to develop or operate Flow network infrastructure.

Practical overview

When it fits

Use Flow Go when the work requires the Flow network implementation itself, node-role software, protocol components or a local Flow development environment. Use the related client or CLI repositories when the task is application access or command-line interaction rather than operating the network implementation.

Who it is for

  • Flow protocol contributors
  • Node operators
  • Blockchain infrastructure teams
  • Developers building applications or infrastructure connected to Flow

Documented uses

  • Build Flow node software for documented node roles.
  • Run or contribute to Flow network infrastructure.
  • Study HotStuff consensus, proof-of-stake and distributed-systems implementation patterns.
  • Develop against Flow’s Cadence ecosystem and related network components.
  • Run a local Flow network for manual testing and integration work.
Before you choose

Requirements & limits

The repository is public and licensed under AGPL-3.0. The documented development workflow uses Go and Docker; no account or pricing requirement is provided.

  • The repository is written in Go and requires Go 1.26 or later.
  • Docker is the recommended route for building and running Flow locally.
  • The codebase covers distinct collection, consensus, execution, verification and access roles.
  • Imported Go projects may require cgo to be enabled because of the cryptography dependency.
  • The documented direct access-node binary build targets Linux/x86_64.

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

Set up Flow Go for local development

Install the documented dependencies and prepare the repository for building, testing and local Flow development.

Before you start

  • A machine with Go 1.26 or later.
  • Docker.
  • Configured GOPATH and GOBIN environment variables, with GOBIN added to PATH.
  • A clone of the flow-go repository.

Steps

  1. Clone the flow-go repository.

  2. Install Go 1.26 or later and Docker.

  3. Set GOPATH and GOBIN, then add GOBIN to PATH.

  4. Run the command below.

    Documented command
    make install-tools

  5. Continue with the repository’s documented build, test or local-network guides.

Expected outcome

The project’s documented tools and environment are installed for Flow development work.

Guide limitations

  • This setup sequence does not document a completed build, test run or network startup.
  • The direct access-node binary target is documented for Linux/x86_64.
