I thought there was some way you could run umpteen daemons or something like that, each basically hoping to be the lucky instance that gets a block, all using the same wallet/stake since there is nothing preventing you using the same wallet/stake in billions of separate copies of the program?
Try a billion times to form the next block, and whichever copy succeeds thats cool, all the copies that failed cost you no coins they are in effect just a kind of hashing, a doing of work, the more different attempts you make to form the next block the greater your chance of doing so, while it costs you no additional stake since all the copies are all using the same stake. Its only the one that actually gets lucky and finds a block that anyone else sees.
As I recall it didn't actually require umpteen copies of the daemon, at least when it was first discussed years ago; you just modify the code to multiply your attempts at successfully finding a block with your stake.
I do not know the details as proof of stake was shot down when Sunny King came out with Peercoin and there has been no word since of anyone ever actually fixing the problem other than Sunny King making some vague handwavings smakescreens or whatever so it all amounted to oh pooh pooh who cares we are all making money so fuck it no oen actually cares that the whole thing is utterly broken from first principles.
The basic problem being it costs no stake to "use" stake for mining so you can use it in parallel as many times as you have RAM and CPU etc enough to do.
