+== Architecture Overview
+
+Dshackle is built using/based on:
+
+- Java Virtual Machine, Java 8+
+- Kotlin
+- Spring Framework, Boot and Reactor
+
+It's own communication protocol is based on Protobuf and gRPC, though it connects to other nodes using different protocols,
+such as JSON RPC or Websockets.
+
+Dshackle connects to actual blockchain nodes and provides an aggregated API automatically directing requests to
+currently healthy nodes. It's built using _reactive_ and non-blocking code and provides low latency and high efficient
+API.
+
+Dshackle servers can be connected to each other as well, or work in parallel, to provide scalable and fault tolerant
+connection to blockchains. All connections can be secured and authenticated with client/server certificates.
