    16  // This structure is necessary to sign the proposal which contains the header

    19  // with large payload
    20  //
    21  // When an endorser receives a SignedProposal message, it should verify the
    22  // signature over the proposal bytes. This verification requires the following

    24  // 1. Verification of the validity of the certificate that was used to produce
    25  //    the signature.  The certificate will be available once proposalBytes has
    26  //    been unmarshalled to a Proposal message, and Proposal.header has been
    27  //    unmarshalled to a Header message. While this unmarshalling-before-verifying
    28  //    might not be ideal, it is unavoidable because i) the signature needs to also
    29  //    protect the signing certificate; ii) it is desirable that Header is created
    30  //    once by the client and never changed (for the sake of accountability and
    31  //    non-repudiation). Note also that it is actually impossible to conclusively
    32  //    verify the validity of the certificate included in a Proposal, because the
    33  //    proposal needs to first be endorsed and ordered with respect to certificate
    34  //    expiration transactions. Still, it is useful to pre-filter expired
    35  //    certificates at this stage.
    36  // 2. Verification that the certificate is trusted (signed by a trusted CA) and
    37  //    that it is allowed to transact with us (with respect to some ACLs);
    38  // 3. Verification that the signature on proposalBytes is valid;
