Seeking Blockchain JTBD Use Case Research

Researching for Blockchain user experience cases on the jobs to be done (Christensen) framework. Although largely invisible to the end user, are there any sources where I research how blockchain might be used for supply chain management or logistics, or for social media or communications use - emphasising trust, security, etc? Are cryptocurrencies, OCIs, etc, still too emergent to conduct guerilla research, enthonography?
