Build on Polkadot
Polkadot is 100% open-source. Anyone can contribute to the codebase, run a node, or build services on Polkadot. You can even get a grant.
Easily build a Polkadot parachain with Substrate
Build your application-specific blockchain with the Substrate framework now and easily connect it to Polkadot after launch.
Native Polkadot compatibility
Blockchains built with Substrate are natively compatible with Polkadot, so they can be easily connected to Polkadot as a parachain or parathread.
Upgrade your blockchain without a hard fork. Your runtime is a Wasm binary stored on-chain and can be updated using your chain’s governance mechanism.
Plug-and-play modular framework
Substrate allows you to simply plug in the functionalities you need, while also giving you the freedom to customize as needed.
By connecting your blockchain to Polkadot, your blockchain will be able to pass arbitrary messages to other chains in the Polkadot network.
With Substrate, you can write your blockchain logic in any language that can compile to WebAssembly (Rust, C/C++, C#, Go, etc).
