> Never heard of XRP before. Very briefly scanning, looks like a distributed consensus type protocol, which isn't anything new doesn't attempt to solve the core concern about decentralised trust. To save you some googling, it _does_ try to solve decentralized trust. It goes for a more traditional scheme, a variant of Byzantine agreement. However, there was a dispute wherein David Mazières (of Kademlia fame) claims that Ripple's design has a flaw, that he fixed in SCP (Stellar Consensus Protocol), by designing FBA (Federated Byzantine Agreement) as described in his paper: https://www.stellar.org/papers/stellar-consensus-protocol.pdf https://www.stellar.org/papers/stellar-consensus-protocol.pd... (which features a comparative description with Ripple and Bitcoin).
