Does `MP-SPDZ` support Public Auditable MPC?

[enricobottazzi]

I'm designing an application in which I require third parties that didn't join the MPC to be able to verify the correctness of the output. I know that there's some research (1 2) available on the topic. I'm wondering if this feature is supported for any protocol in MP-SPDZ.

Not in this repository. I'm aware of some research that builds on top, for example https://eprint.iacr.org/2022/436.pdf. I suggest you check in with the authors if they're willing to share their code.

Thanks for the suggestion. I will reach out. Given the existing research on the topic, which seems to you the best approach to achieve PA-MPC? And would you be interested to integrate it to this repo?

I don't have an opinion on the best algorithm. I'm happy to integrate pull requests that uphold all existing functionality.

Ok, I am on it!
