Be mindful that Data in IdentityInfo is truncated to 32 bytes (see docs), so it is recommended to pass a hash of the data rather than the data itself for stuff like display.

I think you want this

Suggested change
pub identities: Vec<(T::AccountId, String)>,
pub identities: Vec<(T::AccountId, IdentityInfo)>,

I assume this was done to not require trait bounds on the IdentityInfo type?

Even so, it seems much more preferable to be able to specify all other identity-related fields in genesis config, so let's figure out what the trait bounds should be here...

Oh, it's just T::MaxAdditionalFields, so we should just use that:

Suggested change
pub identities: Vec<(T::AccountId, String)>,
pub identities: Vec<(T::AccountId, IdentityInfo<T::MaxAdditionalFields>)>,

Thanks for comments both, I didn't use IdentityInfo initially as it wanted Deserialize<'_>, I agree it is preferable to support this though, I will try to add serde::[Des|S]erialize on these types

That is what i meant with trait bounds. Normally we just use POD types here to not having to use Serde from within the runtime.
I think its fine.

A Vec<u8> would be a bit less biased than a String - otherwise the encoding is not fixed.

We'll probably need BoundedVec then, no reason to not make this derive MEL.

thx, uses BoundedVec now

How much sense does it make not to provide any judgments?
Having no judgement is as good as having no identity at all.
But not sure if its possible without also adding a genesis judge…

Since you suggested it, we are now depending upon you to implement a genesis identity judge :)
