Masternodes perform incentivized services on a 2nd network layer, they mix coins, vote on proposals, run multisig and run services like exchanges/instant transactions. That is of course if theyre being used for function and not perceptual price propping. Weaver and the slush fund can probably be effectively handled by masternodes(although i still have little to no idea what weaver actually is).
And this system you're talking about above sounds more akin to the way shadowtokens work; shadowcash is the main layer, shadowtokens are exponentially created by swapping shadowcash for shadowtokens. They can be swapped back at any time, but i dont think shadowtokens are destroyed ever, havent checked out the project in a few months.
Thats the way i understand it anyway, i may have gotten things slanted. And i agree that full staking should be default.
Thats cool, then they are on the right track. The most important thing is the inductor, or slush fund. Without it price will still go perpetually downwards, with the exception of hyped pumps.
Next to that is the weaver, from what I know of it, it will give Silk the competitive advantage.
