+#### I heard you were moving away from Whisper?
+
+Whisper is not currently under active development, and it has several drawbacks.

+- Proof of work is a poor spam protection mechanism for heterogenerous devices
+- The privacy guarantees provided are not rigorous
+- There's no incentives to run a node
+
