RSK is the Smart Contract platform of Bitcoin. Its engine is a forked version of the EVM (Ethereum Virtual Machine), and the RVM (RSK Virtual Machine) is compatible with Ethereum Smart Contracts and the tools used to deploy and interact with them.
The Smart Bitcoin (RBTC) is the native currency in RSK and it is used to pay for the gas required for the execution of transactions.
