RSK’s virtual machine implementation is compatible with the Ethereum EVM, so we can also use many of Ethereum’s developer tools. The smart contracts themselves can be written in the Solidity programming language because you wouldn’t run Java directly on the Ethereum blockchain. A move to the Ethereum mainnet is expected soon. 0. Introduction.
