Block chain data structure made as an exercise. Inspired by https://github.com/SavjeeTutorials/SavjeeCoin .
ruby src/main.rb
Type in the console:
t1 = Transaction.new('me@email.com', 'he@email.com', 100)
t2 = Transaction.new('he@email.com', 'she@email.com', 60)
block_chain.add_transaction(t1)
block_chain.add_transaction(t2)
block_chain.mine_pending_transactions('me@email.com')
block_chain.balance_of('me@email.com')
