Detailed Description

An object of this class represents a quorum which was mined on-chain (through a quorum commitment) It at least contains information about the members and the quorum public key which is needed to verify recovered signatures from this quorum.

In case the local node is a member of the same quorum and successfully participated in the DKG, the quorum object will also contain the secret key share and the quorum verification vector. The quorum vvec is then used to recover the public key shares of individual members, which are needed to verify signature shares of these members.
