    Our work includes improvements that were merged into Shadow v1.11.0


    We describe a new methodology that enables the direct execution of multi-threaded applications inside of Shadow, an existing parallel discrete-event network simulation framework. Our methodology utilizes function interposition and an application-layer thread library to emulate the ordinary thread interface to the application. Using this methodology, we implement a new Shadow plug-in that directly executes the Bitcoin reference client software. To demonstrate the usefulness of this tool, we present novel denial-of-service attacks against the Bitcoin software that exploit low-level implementation artifacts in the Bitcoin reference client; our deterministic simulator was helpful in developing and demonstrating these attacks. We describe optimizations that enable scalable execution of thousands of Bitcoin nodes on a single machine, and discuss how to model the Bitcoin network for experimental purposes.
