Cloak had anon that was initially believed to be trustless until it became evident that a posa tx could be decrypted hacked by a bad wallet (although very difficult to do so) to reveal sensitive data. It took many weeks after testing for that to surface.
Now SDC is doing something different and very clever. It seems SDC is using a purely blockchain based process for issuing destruction redemption of Shadow and on that basis, if correct, makes the unforgeability very strong indeed.
From whitepaper.
Shadow can be minted, which will destroy SDC
(ShadowCash), and will output a group of Shadow tokens totaling the same value
(minus the transaction fee) of the destroyed SDC.
The obvious weakpoints in SDC anon, if there are any, as pointed out before by people raising questions would have to be the risk of cheating the system for gain.
What would seal the deal in SDC is:
Irrefutable proof that there is no possibility to hack the wallet to allow minting of shadow tokens without destroying SDC of same value.
