CheckPrivateShares

An implementation of p256k1’s MultiMult trait that allows fast checking of DKG private shares We convert a set of checked polynomial evaluations into a single giant multimult These evaluations take the form of s * G == \Sum{k=0}{T+1}(a_k * x^k) where the a vals are the coeffs of the polys There is 1 share per poly, N polys, and each poly is degree T-1 (so T coeffs) First we evaluate each poly, then we subtract each s * G

Nonce

A composite private nonce used as a random commitment in the protocol

PolyCommitment

A commitment to a polynonial, with a Schnorr proof of ownership bound to the ID

PublicNonce

A commitment to the private nonce

Signature

An aggregated group signature

SignatureShare

A share of the party signature with related values

TupleProof

A Chaum-Pedersen proof that (G, A=aG, B=bG, K=(a*b)*G) is a DH tuple

Functions

check_public_shares

Check that the PolyCommitment is properly signed and has the correct degree polynomial

validate_key_id

Check that the passed key_id is valid

validate_signer_id

Check that the passed signer_id is valid

Type Aliases

MerkleRoot

A merkle root is a 256 bit hash
