Summary
Grounded in the theory of effective use, the paper derives ten meta-requirements and eight design principles for blockchain-enabled marketplace interfaces that balance simplicity and trustworthiness, foster learning, provide interoperable identity/reputation, support domain-specific visualizations, add plausibility checks, enable privacy-preserving external storage, offer customized dashboards, and reflect industry-specific processes.
Artifact
A blockchain-enabled marketplace interface (BEMI); the Open3D marketplace instantiation.
Methodology
Design science research; kernel theory (representation); expert interviews yielding meta-requirements; instantiation and evaluation.
