The mods need to move the Ripple stuff to Alt Cryptocurrencies.
Nope, because Ripple is a way to move Bitcoins around.
Ripple is not an alternate currency, although there is a currency built into it. If anything, all of the negative threads that seem to want to focus on this built in currency should be moved. But "Ripple Explained for Bitcoiners!" is 100% relevant to Bitcoin discussion. ...
Ripple had a seat on the 'alternate crypto-currency roundtable at the 2013 conference. I didn't see anyone holding a gun to their heads.
No matter where it happens to be filed, I would not mind it it were open-sourced one of these days. Relatedly, I wish to know the underlying architecture so I can make my own decisions about robustness, scaling, centralization, and that sort of thing. A 'start with all and subtract' scheme was something which hit me some time ago as a means of mitigating against certain kinds of scaling issues. I'm academically interested in knowing whether Ripple has the same basic goal with this design.
