i think healthcare will be next big sector that blockchain can be very useful. EHF can be useful in many developing country like india
To complete my comment beforehand:
My statement sounded a bit negative. I like the idea of EHF a lot. But in my opinion its more for countries where docotrs are not so dense but where people are equipped with technology - you know what i mean?
Ehealth will not cure deseses in africa from a child who has no computer thats what i meant - expressed in a rude manner
