So, their whole blockchain is now useless from a privacy perspective right?
The SDC portion was always equivalent to BTC from a privacy perspective (except for being less used which likely makes it worse in practice).
The Shadow portion has functioning (afaik) stealth addresses but the ring sigs did not function. That makes it equivalent to BTC where addresses are never reused. No 'mixing' function.
You are too much of a gentleman.
It is
much much much worse than bitcoin because people have used the "anonymous" feature of this coin with the expectation of
anonymity. This jeopardizes their freedom, safety, and maybe even life.
It's inexcusable.
No it doesn't. SDT is still functional and SDC ring sig math was fundamentally flawed. I suspect that came from the size changes that were made to increase performance in 2014 which Smooth referenced in December as change he hadn't noticed in the code which I thought at the time was a significant improvement to ring. Just turns out maybe it wasn't or is just buggy. I don't know.
