The blockchain is an immutable chain of blocks. The unique characteristics of the blockchain have made it possible for application in several sectors beyond cryptocurrencies. However, the blockchain is vulnerable to security challenges such as Privacy leakage, Scalability, and selfish mining. Some studies have proposed solutions to improve the security of the blockchain, although these issues still exist. For instance, linking wallet addresses to a user's real identity is still possible. Due to the constant invention of system compromising techniques by adversarial entities, a new perspective is required to understand blockchain security from a strategic and decision-making perspective. Current traditional network security solutions use complicated heuristics approaches. They are inadequate in dealing with advanced and sophisticated threats as these solutions lack dynamic interactions and a quantitative decision framework. There is a need to model the behaviour of blockchain adversarial entities adequately.
Since security measurement is an essential aspect of network security, it evaluates security services and security risks. One aspect of this vital measurement is risk assessment. This project aims to design novel game theoretical frameworks for blockchain security risk assessment.
