public static final class ByzCoinProto.Proof.Builder
extends com.google.protobuf.GeneratedMessageV3.Builder<ByzCoinProto.Proof.Builder>
implements ByzCoinProto.ProofOrBuilder

 Proof represents everything necessary to verify a given
 key/value pair is stored in a skipchain. The proof is in three parts:
   1. InclusionProof proofs the presence or absence of the key. In case of
   the key being present, the value is included in the proof
   2. Latest is used to verify the merkle tree root used in the collection-proof
   is stored in the latest skipblock
   3. Links proves that the latest skipblock is part of the skipchain
 This Structure could later be moved to cothority/skipchain.
