A deployable agile blockchain as a service (aBaaS) framework for construction projects

Purpose: This study aims to develop an agile blockchain as a service (aBaaS) framework for construction projects, which will support blockchain design, deployment and operation in a flexible, agile and cost-effective manner.

Design/methodology/approach: This research adopts a design science research method. The aBaaS framework is then substantiated through two case studies pertinent to construction projects.

Findings: It is found to be highly flexible, achieving high completion rates in customizing the design, deployment and visualization of blockchain systems within given periods. Also, the aBaaS framework is highly agile and cost-effective, capable of responding to changes with low person-day units and labor cost.

Research limitations/implications: Limited sub-service components are built in design management as services (DMSs), deployment as services (DESs) and visualization as services (VISs) of aBaaS framework. Practical implications: This research offers a reference for those aiming to realize the potential of blockchain in construction projects. 

Originality/value: Firstly, it introduces a novel, flexible modular-build DMSs method to help system developers design blockchain systems for projects. Secondly, it improves the blockchain deployment methods by offering plug-and-play DESs for projects. Thirdly, it accelerates the visualization processes for blockchain users in projects by offering them flexible, click-to-go and cost-effective VISs.
