"Blockchain", not bitcoin, and "Blockchain" is quite literally a specific application of Merkle Trees and Merkle Proofs, and they've been used almost exactly like this in payments clearing & settlement + dispute systems for tranlog coherency checks and resolution for a long time.
"Reactive", as in http://www.reactivemanifesto.org/, and it's manifestations in various Akka projects like http://www.reactive-streams.org/.
