Rootstock
Rootstock is the longest running and leading Bitcoin Layer 2 Blockchain. It combines the programmability of Ethereum with the store of value and decentralisation of Bitcoin. Rootstock is secured by over 60% of the hash power of Bitcoin through a consensus mechanism known as Merge Mined Proof-Of-Work. Rootstock uses the Solidity programming language and is fully EVM compatible. This means anything you can build on any other EVM chain can also be deployed on Bitcoin using Rootstock without any additional tools.
