The center of knowledge
Substrate is powered by best-in-class cryptographic research and comes with peer-to-peer networking, consensus mechanisms, and much more.
Substrate developer knowledge base
Discover the principles and design decisions that Substrate is built on. Read about its key features and capabilties as well as the specific skills needed to be an effective Substrate blockchain developer.
The Substrate how-to guides have everything you need to produce robust Substrate based blockchains. From beginner to expert, you can use them flexibly to suit your current needs.
Create your first Substrate chain, perform a forkless upgrade, and more. This selection of tutorials will lead you through the process in sessions of up to two hours.
Set up a cloud sandbox
Building with Substrate requires different pieces of technology. We recommend picking a sandbox if you're just getting started and want to try things out. Or if you're hosting Substrate developer workshops or following tutorials, using a sandbox environment allows you to skip the preliminary set-up to get to the parts most important to you.
