The extent of the mention in the factsheet on her "Tech & Innovation Agenda" is this:
We must position American innovators to lead the world in the next generation of technology revolutions –from autonomous vehicles to machine learning to public service blockchain applications –and we must defend universal access to the global, digital marketplace of ideas.
Pretty unassailable stuff. It is interesting to note, though, that blockchains are mentioned only in the context of public service applications. Most public service applications I can think of, such as identity provision, require open permissionless blockchain networks to achieve universal interoperability and verifiability. We'll be reaching out to her campaign to offer our expertise.
