Which Blockchain to choose? A decision support tool to guide the choice of a Blockchain technology
This addresses the challenge for companies in choosing among many blockchain technologies, though it is incremental as it builds on existing decision models with automation.
The paper tackles the problem of selecting a blockchain technology for companies by building a knowledge base from whitepapers, studies, and benchmarks, and implementing a Multi-Criterion Decision Analysis method to provide automated recommendations based on non-functional requirements, illustrated with a supply-chain use case.
Companies trying to build new solutions using blockchain are confronted with a plethora of available concurrent technologies that have many control knobs which require fine-tuning by experts. Exiting studies that build decision models for blockchain adoption or selection lack an automated way to use non-functional requirements to provide recommendations. In this paper, we build a knowledge base for blockchain solutions by analyzing whitepapers and studies, but also our benchmark results performed in a controlled environment. Then, we implement a Multi-Criterion Decision Analysis method to determine the most suitable blockchain solution from companies provided requirements and preferences. Finally, we illustrate our approach by running the decision process on a realistic supply-chain use case. This paper provides a rationale for blockchain deployment choices. While still limited in scope, we plan to include more blockchain alternative and more flexible requirements inputs in future work.
