My understanding is that in Estonia they were using this technology before it was called blockchain, but it was in 2002 that they implemented a system. The idea is that when they use blockchain as a technology, it's actually when information is being transferred as between departments on a back end. As a citizen, I log on and it's one portal for me, but on the back end, my information is housed in a number of different departments. If they want to share information, those pathways are only open by way of blockchain to ensure that it's private. If I'm at the CBSA, I can't see information that is at employment services...but duly noted on the blockchain concern.
With respect to, I guess, my fundamental question.... I have more specific questions, but this is the broad question. If we build in a digital ID, if we build in anonymization as between departments when they're sharing information and I can log on it and have user control of my information, if those are the three fundamental building blocks of this, am I missing something? Am I missing something else?
