In my thoughts the first situation is the customers at this level, not the tech.
If we may fairly anticipate grandma to correctly safe her non-public key, and register its public key with the federal government, we may probably do fairly safe blockchain voting, with authorities nonetheless performing validation of personhood.
This drawback is not going to go away with time both, it is not likely a difficulty with “boomers” a lot as it’s older persons are simply straightforward to control.
There are nonetheless different logistical points, equivalent to lifeless individuals voting, governments confirming “personhood” of pretend voters, and so on, however I do assume that transparency within the vote may assist rather a lot.
It is a advanced situation, however I imagine the first drawback at this level is the tech-savvyness of customers, not the tech itself.
All of that being stated, I additionally assume individuals extremely underestimate the problems with our present voting programs. It is simple to search out potential issues in a brand new system, however we regularly overlook that the brand new system simply must be higher, not good.
One factor I would like to see is direct democracy, however customers can select to hitch “voting swimming pools”, the place they basically delegate their voting weight to a hopefully extra knowledgeable group they agree with.
