What if I told you there are a few currencies that are taking the serious approach of testing it first, trying to write a decent paper about it and then implementing it?
What If I told you these currencies believe that they are in the accumulation stage while everything is being thoroughly tested and that if you buy in now and when the everything is released and peer reviewed and the gui has had multiple rounds of ux testing and focus groups on the correct orange to use that because of that the universe will adopt it! And all the accumulators will all be rich (back slapping and such ensues.) Sound familiar?
In reality by that time everything will have changed 5 times over.
Or in testing a better idea comes up. What do you do? pivot? Or stay the academic course?
There has to be a balance between security and speed of development/relevance.
And yes new needs security reviews. Preferably multiple.
In my own work I've seen projects actually sink because of the level of documentation and anal retentive box ticking.
So personally I'll side with speed and the prospect of something amazing (even if half of what is proposed is delivered the results will be amazing) over overthorough naval gazing.
