The current circuit uses a Merkle tree to check that input note commitments are in the commitment set. This requires dMerkle = 29 SHA256Compress evaluations to check each input, which is the majority …

While implementing proactive secret sharing protocols, we have come across an issue in that the secp256k1 curve library is very reluctant to let us have a scalar zero or the identity point. This make…

Create “lecture notes” for training new hires on fields, groups, elliptic curves, polynomials and FFTs, polynomial commitments (abstractly), inductive proof systems — with emphasis on relation to prac…

The "joint" channel functionality would be to make all the funding/closing and payments operations to be jointly signed by a group of N entities. This assumes Schnorr support being specified out in Li…

This will have two components:
- Public input packing: Creating the commitment to the public inputs efficiently on one curve.
- Unpacking the public inputs on the other curve.

Hello!
According to the original papers, a dealer of the VSS/DKG schemes has to broadcast polynomials commitments [(Deal.Commitments](https://github.com/dedis/kyber/blob/master/share/vss/rabin/vss.go…

I have tried to reimplement some of the functionality of Singular's `finvar.lib`,
using GAP and its package `GAPJulia` for calling `Singular.jl`,
but some of the Singular kernel features seem to be …

It would be useful if the set of parties providing input polynomials could be different from those providing output shares. Examples:
1. Overcontributing randomness: `n` parties are receiving share…
