If I understand this correctly, dash's Instant Send defeats the Border Gateway Protocol (BGP) issue that can break bitcoin. I would like someone to clarify this, but my understanding is, Instant Send sidesteps the time between block confirmations and thus prevents forks. If that's the case, then I think this message needs to get out more.
