C# LGTM modulo one final nit. Haven't looked at Rust much.

I think in the face of Tyler's proposal that changes identity/address representation altogether, this PR might become obsolete.

@RReverser My understanding is that the Identity type will still be a 32 byte value and in that case, this still makes it more efficient and more amenable to fast access through indices. The Address changes will become obsolete though. I'm holding off on more work on this PR until the picture becomes clearer.

CLI changes LGTM

PR looks good, but did you give any thought to the formatting changes of identity? I personally think they are an improvement, but ymmv.

Ah, see Ingvar's comment above.

Ah the Rust implementation probably needs to revert to original hex stringification as well. We do use identity/address strings in a few places (e.g. configs), so this would be a breaking change.

This is a breaking change anyway but it's a wipe-the-database breaking change rather than a rewrite-your-configs breaking change at the moment.

In that case, I think this is good to merge, but I cannot approve my own PR... :)

Revert U128/U256 formatting changes, they were printing numbers backwards Fix failing test Fix some passing tests, add a failing test Bump serde_json version and add arbitrary_precision feature. This allows passing u128 through serde_json::Value, which is done in the CLI crate.
