Many still spread false news that the voter can take the ballot home, but that's not true, the ballot does not remain in the voter's possession, it is placed in the ballot box

exactly... as I mentioned in a previous text I published here, it's not because it's blockchain that it's secure. A breach can be an entry point to compromise everything. The printed vote is an additional means to verify if the numbers match.

In my view, there are many blind spots (deliberate?) in this.
