Blockchain-based Application Security Risks: A Systematic Literature Review
This work addresses security concerns for developers and researchers implementing blockchain applications, but it is incremental as it synthesizes existing literature without new empirical findings.
The paper conducted a systematic literature review to identify security risks in blockchain-based applications, both mitigated by blockchain and inherent to it, and highlighted domains where these risks occur, resulting in a preliminary checklist for implementation.
Although the blockchain-based applications are considered to be less vulnerable due to the nature of the distributed ledger, they did not become the silver bullet with respect to securing the information against different security risks. In this paper, we present a literature review on the security risks that can be mitigated by introducing the blockchain technology, and on the security risks that are identified in the blockchain-based applications. In addition, we highlight the application and technology domains where these security risks are observed. The results of this study could be seen as a preliminary checklist of security risks when implementing blockchain-based applications.
