https://citizens-initiative.europa.eu/_en, This is the initiative I am talking about. You have to prove you are an EU citizen and then you can sign for the initiatives you want and if a million signatures are reaching within a year then it must be brought to the EU commission.
So if citizens of EU member states can sign online, why can’t they vote online for elections or referendums? If possible, this would decrease the need and power of representative democracy and move closer to direct democracy, which I argue is a good thing
What exactly do you mean, the same downsides?
Mail ballots require physical presence to tamper with, so if you have armed guards + security cameras watching the drop box, most tampering threats can be prevented, at the same time, no one knows who the voter really voted for since envelopes are sealed.
In contrast, internet connections are really easy to tamper with. Most people just blindly click past https warnings, and thats just the most basic attacks, there are more sophisticated attacks. Not to mention, you dont even need physical presense. Anyone, anywhere around the world can hack an online vote.
