Understand the project
Practical overview
When it fits
Use Flow when a project needs a public technical reference for the Flow network or is evaluating development around its proof-of-stake blockchain, Cadence ecosystem and documented interfaces.
Who it is for
- Protocol contributors
- Node operators
- Blockchain integrators
- Researchers
Documented uses
- Consult Flow protocol specifications and access-node architecture references.
- Use protobuf and OpenAPI definitions when investigating Flow integrations.
- Review node-operator documentation and recorded network sporks.
- Research governance proposals, agendas and protocol history.
- Find linked developer and Cadence resources for application development.
Before you choose
Requirements & limits
The repository is publicly available and licensed under Apache-2.0.
- The repository is a reference and metadata hub rather than the Flow protocol’s reference Go implementation.
- It includes both machine-readable interface material and human-facing protocol, governance and node-operator documentation.
- The OpenAPI directory covers the Flow Access API REST surface, while protobuf contains schemas and generated Go bindings.
- The repository links to separate developer-portal and Cadence documentation for tutorials, SDKs, APIs and language material.
- The project is relevant to self-hosted and server-oriented infrastructure work through its node-operator references.
Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
