I often see people that push for electronic voting, mentioning some benefits like reducing invalid votes, avoiding counting mistakes (which might also be deliberate), finding out the results quickly, etc.
I usually try to discourage them using common-sense counter-arguments like: “Let the more advanced countries implement it first, and then Albania can follow in their footsteps.” However some people think that they know a lot about technology and they don’t find such answers satisfactory.
Well, this paper has a full-fledged answer by security experts about internet voting, blockchain voting, etc. These are their conclusions:
- Blockchain technology does not solve the fundamental security problems suffered by all electronic voting systems. Moreover, blockchains may introduce new problems that nonblockchain-based voting systems would not suffer from.
- Electronic, online, and blockchain-based voting systems are more vulnerable to serious failures than available paper-ballot based alternatives. Moreover, given the state of the art in computer security, they will continue to be so for the foreseeable future
- Adding new technologies to systems may create new potential for attacks. Particular caution is appropriate in security-critical applications, especially where political pressures may favor an expedited approach.
