Smart Contracts Vulnerabilities and Countermeasures in Blockchain Security

Abstract

Blockchain technology has revolutionized various domains by introducing decentralized, transparent, and immutable transactions through smart contracts. However, the inherent immutability of smart contracts makes them susceptible to vulnerabilities such as reentrancy, overflow, and timestamp dependency, leading to potential financial losses and security breaches. This paper conducts a thorough literature review, synthesizing findings from reputable sources to comprehensively explore the state-of-the-art in smart contract security. The review presents vulnerabilities with specific attack examples alongside countermeasures based on static analysis tools while adding fuzz testing and a deep learning novelty. Studies of recurring patterns and security method assessments through thematic and comparative methods provide understanding of diverse approaches and their weaknesses. The synthesized details benefit from thorough ethical evaluation and strict quality evaluation processes that enhance their reliability. These results establish a beneficial resource that assists stakeholders to make better decisions because they understand how to strengthen blockchain security in its rapidly changing environment.
