Challenges and solutions on architecting blockchain systems
Gregory Fournier, Fábio dos Santos Petrillo · Espace ÉTS (ETS) · 2018
Despite the fact that companies are gravitating more and more towards the use of blockchains in their systems, it is clear that the blockchains is no silver bullet. Many challenges such as scalability issues and frustrating trade-offs most notable in public decentralized blockchain systems are currently holding back blockchain's huge potential. In this paper we conduct a Systematic Literature Review in order to explore the current challenges of blockchain while presenting possible solutions to each of these challenges. We come to the conclusion that current challenges can be summarized in three categories: Scalability issues, security issues and a choice of consensus protocol. We also briefly discuss the use of blockchain in current systems, concluding that while blockchains current immaturity makes it hard to recommend for most projects, blockchains in their current state could be used in the Internet of Things.
