Paper ballots does not mean absolutely zero computers are involved. I do not know about Germany but in the United States we have voting machines that print paper ballots and those are submitted to a vote counting machine but you can verify your vote before and after printing. Voting machines are important for accessibility reasons. Not every can see or even read English after all. The vote counting machines are then double checked by hand. A blockchain based solution would take significantly longer to verify by hand without a computer and the amount people who could do the cryptographic calculations in a reasonable time frame on scratch paper would mean we would essentially be trusting the results of the entire election to a few people. The average person can count and easily understand that the winner is whoever gets the most votes. I would like to see these machines open sourced and confirmed to never be running on the internet through.
