Bitcoin Hash Based Contest

bitcoin_contest.rb

# Takes a list of people and a set of block hashes and picks people from the list based on their
# position when the block hash is taken modulo the number of participants.
# This assumes there won't be two of the same answer. If there are, the code can be modified to pick the next person in the list, or something like that

The first 12 entries in the list were retweets so they got into the list twice because I was awarding 2 entries per retweet. Following that is the list of 33 likes.
