Abstract: Smart contract technology plays a significant role in various fields for achieving secure and automated transactions without the interference of third parties. There arise certain issues of security and privacy issue during the transaction with the assistance of a smart contract. In this present work, a comparative analysis is carried out between various existing techniques in blockchain-based smart contract techniques. First, analysis is done on the security issue. Second, on the basis of smart contract design. Finally, on privacy issue in smart contract platform. To analyse the performance, metrics such as consumption cost, transaction cost, time overhead and processing time are validated. The cost consumption and time overhead attained for the Auditable Access Control System (AACS) technique is 30,125,894 gas and 3,285 sec. The processing time attained for Online Auto Update Smart Contract (OAUSC) is 2,653 sec. This analysis suggested AACS technique functions better in comparison to other existing techniques.
