RGB Node: sovereign smart contracts backend

Components

This repository contains the following crates:

• rgb-node: main indexing daemon, which can be used as an embedded multi-thread service, or compiled into a standalone binary (rgbd);
• rgb-client: client to work with the daemon and a command-line utility rgb-cli;
• rgb-rpc: a shared crate between rgb-node and rgb-client.

Node Architecture

The node operates as a set of threads, communicating through Crossbeam channels. It leverages microservices.rs and netservices.rs crates, which serves as the node non-blocking reactor-based (see io-reactor) microservice frameworks.

The node daemon has the following components:

• Broker, integrating all services and managing their communications;
• RPC: reactor-based thread managing incoming client connections, notifying them about changes to the subscribed information;
• ...

By default, the node exposes a binary RPC API over TCP, which can be exposed as more high-level APIs (HTTP REST, Websocket-based or JSON-RPC) using special adaptor services.

OS Support

The project currently supports Linux, macOS and UNIX. Windows support is a work-in-progress, requiring downstream io-reactor framework changes.
