Vulnerabilities and Open Issues of Smart Contracts: A Systematic Mapping
It addresses the problem of smart contract vulnerabilities for blockchain developers and users, but it is incremental as it reviews existing methods without introducing new solutions.
The paper conducted a systematic mapping to identify initiatives and tools for analyzing smart contracts to address vulnerabilities and prevent financial losses, but it did not report specific results or concrete numbers.
Smart Contracts (SCs) are programs stored in a Blockchain to ensure agreements between two or more parties. Due to the unchangeable essence of Blockchain, failures or errors in SCs become perpetual once published. The reliability of SCs is essential to avoid financial losses. So, SCs must be checked to ensure the absence of errors. Hence, many studies addressed new methods and tools for zero-bug software in SCs. This paper conducted a systematic literature mapping identifying initiatives and tools to analyze SCs and how to deal with the identified vulnerabilities. Besides, this work identifies gaps that may lead to research topics for future work.
