Abstract
We propose an information theoretical model to analyze blockchains. Recently, blockchain has become a trend in the technology domain. We proposed a model that will help to reduce challenges brought on/posed by this technology. This paper will cover three main sections. First is an introduction about Blockchain. Then, we introduce our method, in which we explain how the least action principle, maximum independent set, and N-Queen solutions are applied to analyze the security of blockchains. Finally, we present our case study implementation, and results.
