Statistical Model Checking of Common Attack Scenarios on Blockchain
This work addresses security issues for blockchain developers, but it is incremental as it applies an existing verification method to new attack scenarios.
The paper tackles the problem of verifying blockchain vulnerabilities before deployment by applying statistical model checking to three real-world attack scenarios (DNS attack, double-spending with memory pool flooding, and consensus delay), analyzing results and proposing solutions to avoid such attacks.
Blockchain technology has developed significantly over the last decade. One of the reasons for this is its sustainability architecture, which does not allow modification of the history of committed transactions. That means that developers should consider blockchain vulnerabilities and eliminate them before the deployment of the system. In this paper, we demonstrate a statistical model checking approach for the verification of blockchain systems on three real-world attack scenarios. We build and verify models of DNS attack, double-spending with memory pool flooding, and consensus delay scenario. After that, we analyze experimental results and propose solutions to avoid these kinds of attacks.
