I haven't stated that I've analyzed the system and believe it sound— it takes significant effort to stand behind such a claim, I haven't had the time, and this is also why I've not released any other software using it. (It's not that it's that hard, but it's a question of priorities. That its already in production, for better or worse, lowers it on my list: If it does turn out to be broken people are already screwed). The underlying RS scheme appears solid, but the exact application in Bytecoin has had less review. But that I can't currently say I'm completely convinced it's solid doesn't at all prevent me from saying that claims otherwise so far presented sound suspect.
