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 v0.3.1
This latest pre-release version of the RChain RNode is the first to run a consensus protocol, introduces a gRPC API, supports execution of Rholang contracts that print to the console via STDERR and STDOUT channels, demonstrates persistence storage of keys, and offers support for systemd.

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.
