RSK Smarter Bitcoin allows for smart contracts on the Bitcoin blockchain. Rootstock (RSK) is a sidechain project that enables turing complete smart contracts through a token called Smart-BTC (SBTC) that is convertible 1:1 with Bitcoin. A key feature is that RSK is compatible with the Ethereum Virtual Machine and contracts can be written in the Solidity programming language. The RSK mainnet is currently running but closed to pre-approved participants.
2. Bitcoin allow smartcontract?
Yes it is allowing smart contracts
Rootstock(RSK) is a project to execute smart contracts (turing complete) to the ecosystem of Bitcoin. It is a Sidechain that
uses as currency the SBTC (Smart-BTC) which is convertible 1: 1 with Bitcoin.
An interesting feature of the solution is that it is compatible with the Ethereum Virtual Machine (EVM) and its contracts
are also written in Solidity.
The RSK mainnet is already running but for the time being its closed to pre-approved participants (whitelisted).
