CIP-0105? | Conway Era Key Chains for HD Wallets

[Ryun1]

The Conway Ledger era introduces many new features to Cardano, notably features to support community governance via CIP-1694. This includes the introduction of the new first class credentials; drep_credential, committee_cold_credential and committee_hot_credential.

We propose a HD wallet key derivation paths for registered DReps and constitutional committee members to deterministically derive keys from which credentials can be generated. Such keys are to be known as DRep keys, constitutional committee cold keys and constitutional committee hot keys. Here we define some accompanying tooling standards.

TODO:

• Add definitions for "Constitutional Committee keys".
• Add rationale for Constitutional keys

@Ryun1 I've put this on the meeting # 74 agenda so you can introduce it & maybe give it a quick review if attendees are up for it? 🤔

[Ryun1]

I have addressed all outstanding todos, and have added this to meeting # 76 agenda.

[rphair]

This is well presented, well maintained in advance & consistent with itself and other updated CIPs. Practically all questions I had when reading the material are answered... one of them right in the Rationale FAQ. This should be well understandable to both users & implementors and useful to the community at large as governance issues come to the fore next year. I would recommend that this be made a candidate at tomorrow's CIP meeting. 👍

Welcome to the family #105 (in anticipation of Last Check at next CIP meeting # 77, 2 weeks from today: https://hackmd.io/@cip-editors/77); please update the directory name & Rendered proposal on branch link 🤩 ... I'll green-tick this as soon as the housekeeping is done ✅

[Crypto2099]

Everything now looks in order from what I can see.

[rphair]

all set then... ready to merge whenever ready from your end @Ryun1 😎
