This is a multi-server Ripple. It is built on a penalty system that applies a force on the multi-hop payment coordination (see multihop.xyz for an interactive simulation). The penalty system advances on Ryan Fugger's original ideas from 2006 of a penalty as an enforcement mechanism.

News: 14/05/2025: Now built "rippleproxy", a HTTPS multi-user proxy that manages a users secret key and counter and interacts with Ripple Inter Server Protocol servers. Also a very basic "ripplebrowser" that is a web UI on top of "rippleproxy". bitbucket.org/bipedaljoe/ripplebrowser
