The document proposes an economic incentive-based solution using Bitcoin to defend against distributed denial of service (DDoS) attacks. It discusses limitations of existing defense mechanisms and outlines a four-layer actor model architecture with a directory manager and transport manager to facilitate negotiations and cross-domain communication. The current work involves matching policies and proposals using the actor model and designing a protocol for incremental escrow transactions using Bitcoin to establish financial incentives at reduced cost for cooperative DDoS defense.
