Blockchain technology (or blockchain for short) has emerged as a foundational technology that provides security through cryptography and consensus mechanisms and addresses the issues of single point of failure and single point of trust. The transparency and immutability of blockchain allows publicly provable and indisputable records to be stored [ 1 ]. Additionally, the introduction of smart contracts into blockchain has broadened its horizon of utility beyond cryptocurrency [ 2 ]. Indeed, blockchain is applied in many application areas: from cryptocurrencies to the Internet of Things (IoT), health care and financial systems, supply chain management, etc. Although blockchain is considered a promising technology, it still has security vulnerabilities that adversaries play through.
