Source repository: github.com/paritytech/chainspecs
A chain specification, or "chainspec", is a collection of configuration information that dictates which network a blockchain node will connect to, which entities it will initially communicate with, and what consensus-critical state it must have at genesis.
You can download chainspec and save it as chainspec.json file, then start the substrate node with the --chain ./chainspec.json flag.
⚠️ For some nodes, you may save chainspec with a different name see
⚠️ For production, it is better to use the chainspec provided in the binary (e.g.,--chain kusama). This repo is designed to contain the latest chainspecs before release (for test purposes).
⚠️ All chainspecs are sourced from the default development branch, not the last release. Source repositories (git submodules) are updated once a week.
