public final class SignedProposal
extends com.google.protobuf.GeneratedMessageV3
implements SignedProposalOrBuilder

 This structure is necessary to sign the proposal which contains the header
 and the payload. Without this structure, we would have to concatenate the
 header and the payload to verify the signature, which could be expensive
 with large payload
 When an endorser receives a SignedProposal message, it should verify the
 signature over the proposal bytes. This verification requires the following
 steps:
 1. Verification of the validity of the certificate that was used to produce
    the signature.  The certificate will be available once proposalBytes has
    been unmarshalled to a Proposal message, and Proposal.header has been
    unmarshalled to a Header message. While this unmarshalling-before-verifying
    might not be ideal, it is unavoidable because i) the signature needs to also
    protect the signing certificate; ii) it is desirable that Header is created
    once by the client and never changed (for the sake of accountability and
    non-repudiation). Note also that it is actually impossible to conclusively
    verify the validity of the certificate included in a Proposal, because the
    proposal needs to first be endorsed and ordered with respect to certificate
    expiration transactions. Still, it is useful to pre-filter expired
    certificates at this stage.
 2. Verification that the certificate is trusted (signed by a trusted CA) and
    that it is allowed to transact with us (with respect to some ACLs);
 3. Verification that the signature on proposalBytes is valid;
 4. Detect replay attacks;
