Some time ago I had made a video elaborating upon how the chain- as well as the proof of work aspect make it into blockchain technology. Thought I share as resource.
Similar to how in the questions I has previously raised in the Ethereum comparison thread on the Technology channel, I think there are a few stumbling blocks to common adoption with this technology. Here, in particular, I think that until bitcoin covers the ugly hashes from the eyes of their users, as well as the nasty aspect of having to copypaste the strings, this can’t quite go public. Some platforms like Steemit do have user accounts with normal names, but actually on Steemit and related project you have even more keys (post key, view key,…).
Do you disagree and maybe think this matters when we got something like paycard - or will this be an issue.
