          Applies only to Hyperledger Fabric.

          • Principal (string) –

            The Amazon Web Services account ID to invite.

      • Removals (list) –

        The actions to perform for an APPROVED proposal to remove a member from the network, which deletes the member and all associated member resources from the network.

        • (dict) –

          An action to remove a member from a Managed Blockchain network as the result of a removal proposal that is APPROVED. The member and all associated resources are deleted from the network.

          Applies only to Hyperledger Fabric.

          • MemberId (string) –

            The unique identifier of the member to remove.

    • ProposedByMemberId (string) –

      The unique identifier of the member that created the proposal.

    • ProposedByMemberName (string) –

      The name of the member that created the proposal.

    • Status (string) –

      The status of the proposal. Values are as follows:

      • IN_PROGRESS - The proposal is active and open for member voting.

      • APPROVED - The proposal was approved with sufficient YES votes among members according to the VotingPolicy specified for the Network. The specified proposal actions are carried out.

      • REJECTED - The proposal was rejected with insufficient YES votes among members according to the VotingPolicy specified for the Network. The specified ProposalActions aren’t carried out.

      • EXPIRED - Members didn’t cast the number of votes required to determine the proposal outcome before the proposal expired. The specified ProposalActions aren’t carried out.

      • ACTION_FAILED - One or more of the specified ProposalActions in a proposal that was approved couldn’t be completed because of an error. The ACTION_FAILED status occurs even if only one ProposalAction fails and other actions are successful.

    • CreationDate (datetime) –

      The date and time that the proposal was created.

    • ExpirationDate (datetime) –

      The date and time that the proposal expires. This is the CreationDate plus the ProposalDurationInHours that is specified in the ProposalThresholdPolicy. After this date and time, if members haven’t cast enough votes to determine the outcome according to the voting policy, the proposal is EXPIRED and Actions aren’t carried out.

    • YesVoteCount (integer) –

      The current total of YES votes cast on the proposal by members.

    • NoVoteCount (integer) –

      The current total of NO votes cast on the proposal by members.
