Serious question to senior members. Mazacoin seems like a good project. Is it possible to do a community takeover of it and block/invalidate the premined addresses?
No
To block/invalidate any addresses goes against the whole idea of "Bitcoin" and related projects.
Interesting concept though. If 50% of the network forced a copy of the wrong blockchain to destroy the early coins or adopted a community driven maza that started with the block right after the premine what would that do? Like copy the source and start the block count later and have everyone synch with that instaead of the original maza client?
