Empirical analysis of transaction malleability within blockchain-based e-Voting

Blockchain is a disruptive technology that has been used to address wide range of challenges in diverse domains including voting, logistics, healthcare and finance. Transaction malleability one the critical threats for blockchain, which can facilitate double-spending attacks by tampering with state blockchain. This paper investigates potential transaction attack within blockchain-based application (e-voting) aim identify settings lead successful attack. Therein, we highlight conditions cause so as help develop appropriate protection mechanisms. In particular, execution presented was conducted on blockchain testbed hosting an e-voting application. The experiments identified significance parameters such network delay block generation rate successfully execute have highlighted directions future research.
