-### Milestone 3
+- Change how Hotspots route data packets by replacing its `state_channel` client from erlang to rust, taking advantange of the improvements in gRPC and data streaming (in progress)
+- Update how Hotspots receive, emit, and acknowledge proof-of-coverage receipts from erlang to rust (in progress, targets milestone 4)
+- Implement the work to move Challenge creation to Validators from Hotspots, to be gated behind a chain variable (HIP in progress)
+- Activate the chain variable to move Challenge creation to Validators (to be announced)
+  - At this point, existing Hotspots no longer need to sync or absorb the blockchain, and will satisfy another property of Light Hotspot
+  - Hotspots existing on-chain will be able to participate in Proof-of-Coverage, no longer need to syncronize the blockchain, and will require less computational power (Milestone 4)
