Rootstock

Rootstock (RSK) is a smart contract platform that brings Ethereum Virtual Machine (EVM) compatibility to the Bitcoin network by operating as a Bitcoin sidechain secured through merged mining with Bitcoin’s proof-of-work. Launched in 2018, Rootstock enables developers to deploy scalable, interoperable, and fast decentralized applications (dApps) while leveraging Bitcoin’s security and network effects. Its native token, rBTC, is pegged 1:1 to Bitcoin and fuels DeFi protocols on the platform.

Rootstock’s primary features include seamless EVM compatibility, a native two-way bridge called PowPeg for asset transfers between Bitcoin and Rootstock, and integration with over 20 major blockchains such as Ethereum, Arbitrum, and Base. This interoperability allows developers to port existing Ethereum dApps or build new ones that benefit from Bitcoin’s security and liquidity. The platform supports standard Ethereum developer tools, including MetaMask and JSON-RPC APIs, and offers SDKs, starter kits, and comprehensive documentation to accelerate development.

What sets Rootstock apart is its security model anchored in Bitcoin’s hash power through merged mining, providing one of the most resilient blockchain infrastructures with 100% uptime since launch. Its PowPeg bridge is a decentralized mechanism that locks BTC on Bitcoin and issues rBTC on Rootstock, enabling trust-minimized asset movement. Rootstock’s ecosystem includes over 150 partners and popular DeFi protocols like SushiSwap, Beefy, and Oku, demonstrating real-world adoption. Developers can also access funding through the Rootstock Collective DAO and participate in hackathons and community programs to grow their projects.

To get started, developers can install MetaMask configured for Rootstock, explore the official documentation for deploying smart contracts, and use the PowPeg app to acquire rBTC. Rootstock’s open-source tools and active Discord community provide ongoing support. The platform’s focus on combining Bitcoin’s security with Ethereum’s programmability makes it a compelling choice for teams building DeFi, DAO tooling, and enterprise blockchain solutions on Bitcoin.
