The Economist just published a story about the expanding influence of bitcoin, in which it mentioned Ripple, a new open-currency system. This reminded me of Ripple Pay (which I was very excited about in 2006), but I cannot figure out if it is actually the same system. The Ripple Pay websites are offline, and the Wikipedia article only mentions the name of a single developer, who does not seem to be involved in the new service, Ripple. Also, the logo is different for the two companies.
Still, the new Ripple does seem to include an IOU system, which was the core of Ripple Pay. Does anyone know more?
