A Review of Blockchain Platforms Based on the Scalability, Security and Decentralization Trilemma

Abstract

As blockchains are more and more used to support information system architectures, the question of the suitability of a blockchain technology for a particular system arises. However, given the vast amount of existing blockchain platforms, this choice is difficult as each blockchain focuses on different aspects. The most critical ones are scalability, security, and decentralization, which make up the blockchain trilemma. We review a selection of the most popular blockchain platforms based on their blockchain trilemma properties and related aspects. Then, the platforms will be analyzed on the three aspects of the blockchain trilemma.
