def print_newBlock(self, i):
print("<STR_LIT>" % i)<EOL>
Is called when a block is received

            :param str i: The hash of the block

            .. note:: Unfortunately, it is currently not possible to
                      identify the block number for ``i`` alone. If you
                      need to know the most recent block number, you
                      need to use ``bitshares.blockchain.Blockchain``
