The bitcoin protocol enables us to experiment with bitcoin bounties in new ways and allow us to build bounties directly into our website. To detect intrusion, we can set up automatic notifications when we see movements on specific bitcoin addresses, thereby building a bitcoin layered intrusion detection system.
