Enhancement of Security and Privacy of Smart Contracts in Blockchain

Abstract

Smart contracts, leveraging the power of blockchain technology, have revolutionized the execution
and enforcement of agreements. However, their adoption also brings forth substantial challenges in
terms of security and privacy. This research paper aims to identify the recent areas of focus and
provide a comprehensive perspective on blockchain applications and smart contracts, highlighting
their main issues and corresponding solutions. Furthermore, it seeks to address the gaps in current
research and outline future avenues of investigation. The primary objective is to assess the security
and privacy concerns associated with smart contracts in blockchain and propose effective measures
to enhance their robustness. By conducting a thorough analysis of vulnerabilities, attack vectors, and
privacy considerations, this study offers valuable insights into the risks involved in smart contracts.
It also puts forth practical solutions and best practices to mitigate these risks, ensuring a more secure
and privacy-preserving environment for the deployment and execution of smart contracts.
