Hi,

I'm full supporting this document, as it clarifies the grey area between "validators MUST take any valid path" and "signers MUST sign will all algorithms in DS set", and simplifies algorithm roll-over, while enabling so far impossible operational modes like different-algorithm multi-signer.

Regarding the specific "TL;DR" motivational section, I consider it comprehensible and helpful.

I'm looking forward for this document to move forward.

Hi,

We've updated draft-huque-dnsop-multi-alg-rules yesterday (mostly editorial/clarity fixes).

A significant addition though is the insertion of new Section 1, called "tl;dr: Nutshell Proof of Sanity".

Without going into solution details, this section is trying to establish a baseline understanding of why the proposed adjustment of validation rules is neither far-fetched nor dangerous, but actually a very natural refinement.

You can read the tl;dr here, it's pretty short: https://www.ietf.org/archive/id/draft-huque-dnsop-multi-alg-rules-07.html#name-tldr-nutshell-proof-of-sani

Note that the proposal does NOT change anything for validators which follow algorithm support requirements. It only affects validators with a local policy to not support a mainstream algorithm which they would be expected to support. The goal is to adjust things slightly, to handle this case more gracefully.


The authors would like to encourage discussion about this baseline objective (without going into the "how" of the proposal).

We'd like to hear both support for and technical objections to the Nutshell Proof of Sanity, so we can put subsequent work on more solid footing.

Thanks!

Cheers,
Peter
