Comparing two versions of DKGPRE, where the sensitive material is held by a (a) highly available semi-trusted 5-of-5, or (b) a larger clique that is arguably more collusion-resistant but has greater brick likelihood There's a similar but non-uniform risk with respect to the setup/summoning. How does this differ for (a) and (b)?
Such a good question, @arjunhassard.
A) Seed Distribution 1) Who/what distributes the seed to the participating nodes? 2) Does the seed need to be verifiably random?
B) Shared inputs (share indices) 1) Do they have to be secret, like they are in Umbral?
C) Aggregating the KFragSlivers 1) Can this happen later, at the point that they are actually used (i.e. the Grant phase)?
