Rootstock is the first and longest-running Bitcoin sidechain, fully compatible with the Ethereum Virtual Machine (EVM). By using the Solidity programming language, it ensures seamless interoperability with Ethereum-based applications.
On mainnet since 2018, Rootstock is secured by over 80% of the hash power of Bitcoin through a consensus mechanism known as Merged Mined Proof-Of-Work. It also uses a 1:1 to Bitcoin pegged native token RBTC that allows you to interact with DeFi protocols and dApps on the Rootstock network. You can use RBTC for minting, swaps, gas fees, and more.
