          Use the Block API to retrieve the contents of various blocks from the
          blockchain. The returned Block message structure is defined inside
          fabric.proto.
  
          ```golang
          message Block {
              uint32 version = 1;
              google.protobuf.Timestamp Timestamp = 2;
              repeated Transaction transactions = 3;
              bytes stateHash = 4;
              bytes previousBlockHash = 5;
          }
          ```
  
          :param block: The id of the block to retrieve
          :return: json body of the block info
