Basic functionality for proofs of spend and non-spend status: github.com/SarangNoether/skunkworks/tree/audit-proof

Right now assumes view key access, but can be trivially modified to accept individual DH shared secrets instead

The verifier also gets passed full public/private keypairs, but that's just for data structure convenience; the verifier never needs or uses the private spend key

CLSAG C++ code, rebased for up-to-date test coverage: github.com/SarangNoether/monero/tree/clsag-rebase

(new branch... earlier one had a merge that made rebase irritating)

this Tezos thing is going out of control..

sorry

Quiet channel today!

I'm updating the key image MPC computation protocol for Triptych/Omniring/RCT3 for security against malicious players, and rewriting it with proper player state

It's... tedious

Tedious but necessary I guess :-P

Initial working version: SarangNoether/skunkworks 89802ec

^ just for the key image MPC
