IMPORTANT NOTE:

It's come to my attention that some people have been spamming issue trackers with a link to this gist. While it's a good idea to inform people of the situation in principle, please do not do this. By all means spread the word in the communities that you are a part of, after verifying that they are not aware yet, but unsolicited spam is not helpful. It will just frustrate people.

Update 3 (May 24, 2021)

A number of things have happened since the last update.

This document was originally written several years ago. At the time I was working as an execution core verification engineer at Arm. The following points are coloured heavily by working in and around the execution cores of various processors. Apply a pinch of salt; points contain varying degrees of opinion.

It is still my opinion that RISC-V could be much better designed; though I will also say that if I was building a 32 or 64-bit CPU today I'd likely implement the architecture to benefit from the existing tooling.

Mostly based upon the RISC-V ISA spec v2.0. Some updates have been made for v2.2

Original Foreword: Some Opinion

The RISC-V ISA has pursued minimalism to a fault. There is a large emphasis on minimizing instruction count, normalizing encoding, etc. This pursuit of minimalism has resulted in false orthogonalities (such as reusing the same instruction for branches, calls and returns) and a requirement for superfluous instructions which impacts code density both in terms of size and

How do I verify the Sapling MPC?

What you'll need

1. Install the Rust compiler. A version from a year ago will work but the recent one is fine too.
2. Download the transcript from the Powers of Tau MPC. (See the links here.)
3. Download the params file from the Sapling MPC.
4. Check out the attestations for the Powers of Tau MPC. (Similar can be found for the Sapling MPC but participants chose various ways to distribute their attestations, they have not been coalesced into a single repository.)
