[tracking] Provide group key derivation at genesis proof

[dstadulis]

Wrapper issue to track https://github.com/Roasbeef/bips/pull/33

[halseth]

It could make sense to divide this into PRs

• [x] Add versioning https://github.com/lightninglabs/taproot-assets/pull/381
• [ ] Add asset_genesis and asset_group_key_reveal to proof file (version >= 1)
• [ ] Verify asset_genesis and group_key at initial mint: https://github.com/lightninglabs/taproot-assets/pull/448
• [ ] Verify asset emission against group key (virtual tx state transition)

[jharveyb]

Worth noting we're planning to not actually bump the proof file version, but yes this SGTM.

[halseth]

Verify asset_genesis and group_key at initial mint.

Picking up this one.

[Roasbeef]

Needs to be split up into individual issues for the next jaunt.

[halseth]

Verify asset_genesis and group_key at initial mint.

Starting this one

[guggero]

Add asset_genesis and asset_group_key_reveal to proof file (version >= 1)

I'm starting this one. @halseth I hope that's not something you're already working on (tracking issue https://github.com/lightninglabs/taproot-assets/issues/441).

[halseth]

@guggero I have started this one:

Verify asset emission against group key (virtual tx state transition)

so make sense for you to take on the proof file 👍

@halseth would that include populating the witness in the minted asset as well? Thinking of which may not yet have a PR started for implementing them.

[halseth]

@jharveyb If you want to make a PR for populating the witness, feel free to do so! This is a starting point I used just for prototyping it: https://github.com/halseth/taproot-assets/commit/7e8506542545b256614d05c8224a363e3f375ab2#diff-cba29164382adad1ea3c845d266d8fb28e183f1a83e2f8940b23f38d1b608e95R511

However I'm travelling this week, so won't have the chance to make it into a proper PR before next week.

Additional items:

• [ ] Expose methods for issuers to specify the tapscript root via RPC

[Roasbeef]

Verify asset emission against group key (virtual tx state transition)

@jharveyb will make a tracking issue for this

[jharveyb]

New tracking issues for last two tasks are #465 and #466 .

[jharveyb]

All components are tracked, superceded by #466 and #511 .
