Pedersen DKG implementation questions #2512

Couple of questions about Pedersen'd DKG:

Looking at

cothority/dkg/pedersen/dkg.go

Line 106 in e0c9afb

errs := o.Broadcast(&Init{Wait: o.Wait})

and then the SendToTreeNode implementation I am not clear if you are using private and reliable broadcast channels as required for Pedersen DKG.

We do need to send s_{ij} secretly from i to j.

Have you covered the situation when a faulty process sends bad shares? Do we detect such failures?

That looks like a great question :) I think that this repository should be archived - what do you think, @pierluca ?
