In the current world in which we are trying to digitize everything we can in the name of convenience, security and innovation, we are encountering problems that cause aspects that should have been digitized long ago to continue to rely on paperwork, manual counting and not deviate from the ways of a few hundred years ago.
Such an area is, among other things, voting, each of us would like to cast a vote for our candidate without necessarily leaving home and without necessarily doing it by mail, the simplest and yet most difficult solution we can think of is electronic voting.
Here we encounter further difficulties, politics is such a sensitive topic that the more so online there will be many people who will try to influence the election result, hack it or introduce multi-voting.
With help to implement e-voting comes blockchain technology, which is already proving itself in this formula in the field of DAO (Decentralized Autonomous Organization), where members of the organization have one vote to register regarding a specific question on a referendum basis.
Such a solution can in the long run be brought to the national level, registering each citizen (those who wish to cast an electronic vote) on a single blockchain giving a unique address and the ability to cast a single vote.
For such a solution, a national blockchain network would have to be created where the network would be maintained by multiple trusted individuals, in this case probably citizens, the network would have to be secured against front-running attacks, and a registry would have to be put in place so as to prevent the creation of multiple addresses by a single person.
A feature of such a solution is that votes would not have to be counted by individual people only the system would do it automatically.
In my opinion, public voting via blockchain is a matter of about 20 years.
