Blockchain out of the box - Where is the blockchain in blockchain-as-a-service?

Abstract

Blockchain-as-a-Service (BaaS) is increasingly discussed as a way for companies to get started with blockchain projects. Different BaaS offerings are available, but a systematic categorization of what BaaS comprises is missing. In this research, we analyze the service offerings of BaaS providers based on available online information and identify a number of common characteristics in the BaaS offerings related to the use of service types, distributed ledger technology (DLT) systems, consensus mechanisms, and pricing models. These characteristics are then further analyzed in the light of available literature on BaaS, as well as conducted expert interviews. The objective of this research is to provide an overview of the BaaS landscap,e as well as a taxonomy that provides guidance for researchers and practitioners alike interested in BaaS.
