EM-Bitcoin

The Bitcoin protocol implemented using Ruby's EventMachine. Initially extracted from bitcoin-ruby.

Using EventMachine::Bitcoin::Connection to connect to the Bitcoin network

require 'em_bitcoin'

gem 'em-bitcoin'

Remember that you always need to start the EventMachine event loop. You can't just do this:

EventMachine::Bitcoin::Connection.connect_random_from_dns

You'll need to do this:

EventMachine.run do
  EventMachine::Bitcoin::Connection.connect_random_from_dns
end

You can override the EventMachine::Connection methods to provide your application-specific logic. Such as:

class TxCounter < EventMachine::Bitcoin::Connection
  def post_init
    super
    @tx_count = 0
  end

  def receive_data(data)
    super
    @tx_count += 1
  end

  def unbind
    puts "Total transactions were: #{@tx_count}!"
  end
end

EM.run { TxCounter.connect_random_from_dns }

TODO

• Put lisence in gemspec
• Rework the integration points to both EM and the Bitcoin parser
• Write some tests
• Write some examples
