I noticed that in HoneyBadgerMPC if a single node crashes, the protocol output is not affected, that is, the output delivery is guaranteed.
I am wonderring who did you do it?
I am a new researcher, maybe the question is too simple, but it bother me a lot. Thanks for answer!

Hi Lei, thanks for your interest!
The main idea is we use error correcting codes.
Some references include papers like:
https://link.springer.com/content/pdf/10.1007/978-3-540-78524-8_13.pdf
which is also explained as the "BatchPubReco" method from the honeybadgermpc paper

Thanks for your kind answer!
However sorry I do not find "BatchPubReco" method. Do you mean the following link is the honeybadgermpc paper?
