Human-Data Interaction (HDI) and blockchain: an exploration of the open research challenges for the construction community

Challenges for human-data interaction (HDI) have not yet been contextualized within blockchain implementation in construction. In this positional paper, a focus group accepts the EC3 HDI Committee’s working definition of construction specific HDI, and identifies technical (immutability, data storage, transparency, system design, integrating technologies), non-technical (ethics, economic models, environmental, political, social), overlapping (governance, usage, analysis, control) factors to be considered intersection blockchain. Those considerations led open questions future research efforts – e.g., regarding what types (and associated HDI) are suitable when implementing built environment.
