Blockchain Technology

Bitcoin’s success has led to significant interest in its underlying components, particularly blockchain technology. Over 10 years after Bitcoin’s initial release, the community still suffers from a lack of clarity regarding what properties defines blockchain technology, its relationship to similar technologies, and which of its proposed use-cases are tenable and which are little more than hype. In our research,1, we have answered four common questions regarding blockchain technology: (1) what exactly is blockchain technology, (2) what capabilities does it provide, and (3) what are good applications for blockchain technology, and (4) how does it relate to other distributed technologies (e.g., distributed databases). Our finding show that Blockchain technology is most appropriate under three conditions: (a) a need for shared governance and operation (i.e., not trusted central parties can conduct any of these responsibilities), (b) auditable state, and (c) resilience to data loss.

We are currently exploring applications for blockchain technology in two areas. First, distributed document management for health care. Second, supporting multi-organizational humanitarian aid and disaster relief. In both these situations, there is no central authority to handle governance and operation, but there is a need for organizations to work with each other. Our research aims to build tools that will support both of these use cases, including in situations with limited Internet connectivity—situations which are critical for both applications, but which are not currently well-supported by existing blockchain techniques.

Abstract: Bitcoin's success has led to significant interest in its underlying components, particularly blockchain technology. Over 10 years after Bitcoin's initial release, the community still suffers from a lack of clarity regarding what properties defines blockchain technology, its relationship to similar technologies, and which of its proposed use-cases are tenable and which are little more than hype. In this paper we answer four common questions regarding blockchain technology: (1) what exactly is blockchain technology, (2) what capabilities does it provide, and (3) what are good applications for blockchain technology, and (4) how does it relate to other distributed technologies (e.g., distributed databases). We accomplish this goal by using grounded theory (a structured approach to gathering and analyzing qualitative data) to thoroughly analyze a large corpus of literature on blockchain technology. This method enables us to answer the above questions while limiting researcher bias, separating thought leadership from peddled hype and identifying open research questions related to blockchain technology. The audience for this paper is broad as it aims to help researchers in a variety of areas come to a better understanding of blockchain technology and identify whether it may be of use in their own research.
