The RChain platform supports multiple blockchains both public and private, even on the same node. These blockchains are secured by the type of consensus protocol - proof-of-stake enabling the blockchains to interact securely and predictably. The Smart contracts are verified on Rchain and are written in RhoLang. Rholang contracts run on the Rho Virtual Machine - a concurrent execution engine that allows the applications to achieve significant speed and scalability. RHOC is an ERC-20 Token that will work as the access token to those who want to support the development of the RChain Platform. It represents the value that the early adopters gave it by supporting the RChain project.
