Starting with the node-template, I switched my chains block authoring from Aura to Babe, which compiles fine but does not manage to finalize any blocks. I suspect it's a wrong genesis configuration. The RPC call for grandpa roundState shows the following:

{"setId":0,"best":{"round":1,"totalWeight":2,"thresholdWeight":2,"prevotes":{"currentWeight":1,"missing":["5GoNkf6WdbxCFnPdAnYYQyCjAKPJgLNxXwPjwTh6DGg6gN3E"]},"precommits":{"currentWeight":0,"missing":["5FA9nQDVg267DEd8m1ZypXLBnvN7SFxYwV7ndqSYGiN9TTpu","5GoNkf6WdbxCFnPdAnYYQyCjAKPJgLNxXwPjwTh6DGg6gN3E"]}},"background":[]}

Not sure what I can extract from that.

My question is which part of the code is responsible for proper finalization.

  • You can take a look at this template. BABE and GRANDPA come built-in to the template.

  • How many nodes are you running? Are blocks being produced? Commented Apr 21, 2022 at 9:18
  • Are you getting an Unexpected epoch change error? Please include the errors coming from the terminal logs if there are any. This could be what you're looking for: github.com/paritytech/substrate/issues/4464 Commented Apr 21, 2022 at 11:10

I eventually solved it by removing the AuthorityDiscovery pallet, which I had integrated as well and was most likely just misconfigured.

Run the command of windows Power shell for update nightly:

  1. rustup update nightly

  2. rustup target add wasm32-unknown-unknown --toolchain nightly

  3. rustup update

  4. after that run build command: cargo build --release
