Understand the project

Practical overview

When it fits

Use Neo when the task requires the Neo protocol implementation or its documented development components. Select neo-node for the program that starts a node and neo-vm for the virtual-machine component.

Who it is for

  • C# and .NET developers targeting the Neo ecosystem
  • Blockchain protocol contributors
  • Teams preparing self-hosted Neo node infrastructure
  • Smart-contract developers working with NeoVM

Documented uses

  • Build or extend Neo protocol functionality
  • Develop blockchain applications targeting Neo
  • Prepare a self-hosted Neo node using the related Neo-CLI project
  • Develop or test smart-contract execution with NeoVM
  • Study or contribute to the Neo C# codebase
Before you choose

Requirements & limits

The repository is publicly accessible and MIT-licensed. It identifies Linux, Windows and macOS, as well as CLI, server and self-hosted environments.

  • The main repository is a protocol library, not the node-starting program.
  • Neo-CLI and NeoVM are separate related repositories.
  • The documented implementation language is C#.
  • The repository includes guidance for architecture, building and testing, node operation, smart contracts and contribution.

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

Prepare the Neo development repositories

Identify and obtain the Neo components needed for protocol, node or virtual-machine work.

Before you start

  • A development environment suitable for the C# and .NET codebase.
  • The Neo repository and, where required, the related neo-node and neo-vm repositories.

Steps

  1. Start with the repository's getting-started documentation.

  2. Use the architecture documentation to determine whether the task belongs to neo, neo-node or neo-vm.

  3. Follow the documented build-and-test guidance for the relevant repositories.

Expected outcome

A repository layout aligned with the documented Neo core, Neo-CLI and NeoVM component boundaries.

Guide limitations

  • This setup guidance does not document a completed build, node launch or smart-contract execution.
  • The neo repository itself is a protocol library and does not start a node.
