This is a multi-server Ripple with person-to-person consensus only. 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 idea of a penalty as an enforcement mechanism. This implementation also solves the Two Generals' Problem, something Ryan Fugger never did in his original Ripple Inter Server Protocol design ideas as far as I am aware (Ryan did address user-to-user consensus as early as 2006 here, that state changes had to be agreed on, but never mentioned how to do so as far as I know).
