I have yet to see even a concept, never mind a product, that actually uses a blockchain in a net-positive way, especially for "the unbanked". Universally high transaction fees and slow confirmation times on anything that sees leitimate amounts of use with no clear path towards mitigating this situation, if it's even possible to mitigate at all, combined with several choices of security system each with devastating concequences - from the morally black proof-of-work burning precious resources at a time climate change is already threatening to destroy us, to the morally grey proof-of-stake that simply reinforces the idea that those with the most resources deserve even more resources - makes for something that doesn't seem to have much potential for _good_. The "Unbanked" aren't going to be served by these systems, they need efficient, reliable, and safe systems.
