A Pattern Adherence Analysis to a Blockchain Web Application

Blockchain is an emerging technology that is attracting a lot of attention from both academia and industry. Blockchain when used as a decentralized technology could be utilized in various useful applications, such as healthcare, logistics, supply chain management, education, among others. However, there is the integration factor between technologies and environments, which have their own characteristics and challenges. A pattern is a solution with reusable fetures for a problem that commonly occurs in a given context during software design phases. Usually, when adopting a design pattern, there are trade-offs among quality attributes. In this context, using patterns can promote a better use for blockchain in traditional application and system development, and disseminate best practices. The aim of this paper is to analyze a traditional web application that uses blockchain features from the viewpoint of some patterns, specifically patterns that describe the blockchain integration with the outside world. As a result, we found that applying blockchain patterns can benefit systems, especially those that require integration with other systems, such as legacy or existing.
