This is not correct, you need to get the hasher used by the Block
type. For most chains this is blake256, but not for all.

I mean "not correct" not being really the right term here, but if we want to fix this, we should fix it properly.

I don't know how to do that, and there are many places where this hash is already hardcoded to be blake2_256
. How about we merge this and create an issue to make the hasher depend on the Block
?

Change the function to take H: Hash
and then you can pass HashingOf<Block>
on the calling side of this function.

Thanks, it was easier than I expected.

Ty!
@tmpolaczyk could you add some prdoc? Then accept my changes and we can merge it. |

…aritytech#3447) Changes the runtime hash algorithm used in `resolve_state_version_from_wasm` from `DefaultHasher` to a caller-provided one (usually `HashingFor<Block>`), to match the one used elsewhere. This fixes an issue where the runtime wasm is compiled 3 times when starting the `tanssi-node` with `--dev`. With this fix, the runtime wasm is only compiled 2 times.
