This sounds like a pretty great idea if I understand it correctly. My cynical view of the business of science says it'll never get traction but the base idea sounds like a great way to get rid of a lot of cheating methods. It would also result in research that I'd immediately trust. Alas it's probably possible to game this theoretical system because you can still upload faulty data that leads to the desired results since the registered code can probably be reversed somewhat easily/would be open. I think there's two issues (which can also be combined). 1) Fake/false data. 2) Fiddling with methods until you get the results you want given a fixed data set. Your solution would be excellent for getting rid of problem #2. I think #1 is quite a bit harder and I haven't come up with anything better than "as open as possible"
