Scalable, Secure, Sustainable
Welcome to the developer site for the RChain platform. This is a hub for content to help you learn about and get started with RChain. This is also a hub for developers who want to participate in the project or plan to build on the RChain platform. If you don't find what you need, please see the FAQ or post your question in the forum.

Nodes form the RChain peer-to-peer network. The network layer is the lowest level component in the architecture that will eventually support RChain’s large-scale blockchain operations.
RNode v0.4.1
This version of RNode introduces cryptographic functions to the Rholang language to support both consensus and Rev system contracts, additional metrics for use in monitoring RNode and RSpace performance, a transition to transport layer security (TLS) for communications, and new features to the Rholang language.

Rholang is a new language for writing smart contracts that run on the RChain virtual machine. Developers can write and run Rholang in RNode, the node of the RChain blockchain. Rholang can also be run using community-developed tools. See below for more information and links to these tools.

RSpace is a Scala library that has been designed to provide a disk-based tuple space that both meets the persistence needs of RChain’s Rholang project and offers a novel storage model for developers to use in their own projects.
