Ripple has only just now, in 2018, published their decentralized consensus algorithm (Cobalt), which as far as I know is not even in production use yet, and doesn&#x27;t provide optimal safety. (In settings where Cobalt is guaranteed Safe, SCP would be too, but not vice versa.) Their production network still uses a protocol that, by Ripple&#x27;s own analysis (https://arxiv.org/pdf/1802.07242), fails to guarantee safety without &gt;90% agreement on the UNL.</p><p><a href="https://hackerpaper.kaipfister.de/p/1802.07242/">Paper and discussion history</a>.
