Which Blockchain to choose? A decision support tool to guide the choice\n of a Blockchain technology

Abstract

Companies trying to build new solutions using blockchain are confronted with\na plethora of available concurrent technologies that have many control knobs\nwhich require fine-tuning by experts. Exiting studies that build decision\nmodels for blockchain adoption or selection lack an automated way to use\nnon-functional requirements to provide recommendations. In this paper, we build\na knowledge base for blockchain solutions by analyzing whitepapers and studies,\nbut also our benchmark results performed in a controlled environment. Then, we\nimplement a Multi-Criterion Decision Analysis method to determine the most\nsuitable blockchain solution from companies provided requirements and\npreferences. Finally, we illustrate our approach by running the decision\nprocess on a realistic supply-chain use case. This paper provides a rationale\nfor blockchain deployment choices. While still limited in scope, we plan to\ninclude more blockchain alternative and more flexible requirements inputs in\nfuture work.\n
