I really like the concept of a 1 user 1 vote type of system, but until we have people parties and proof of personhood this most likely won’t work as intended. For example, look at the voting power that DFINITY currently holds, and how this voting power is distributed over many neurons DFINITY Foundation Voting Power - #2 by diegop
Therefore, randomly assigning neurons a “jury vote” will just encourage whales to split their neurons and voting power more sparsely, or encourage a system where users split their neurons as many times as they possibly can to game the system. This would actually counteract a fair 1 person 1 vote system, as a group of motivated enough whales could create a bunch of accounts and split their neurons as many times as possible across those accounts, and then open up the possibility where they are voting 5, 10, 50 times per preliminary period on proposals. As far as I can see, the only way currently to fairly hold a preliminary voting round (until proof of personhood is established) is to take this idea from @ArjaanBuijk
