# MULTISIGS - PART ONE - GENERATING A MULTISIG ADDRESS & REDEEM SCRIPT
# wobine code for world bitcoin network blackboard 101
# Educational Purposes only
# Python 2.7.6 and relies on bitcoind & bitcoinrpc & wobine's github connection file
# We had to change the bitcoinrpc 'connection.py' file to add multisig support
