 ### Plan
 
 - [ ] Network support (should be able to fetch a block)
-  - (wip) RLPx
-  - (wip) Wire protocol
+  - Wire protocol
+    - Discovery protocol
+      - 
+  - [RLPx](https://github.com/ethereum/devp2p/blob/master/rlpx.md) should now be more or less implemented. The problems remaining I think are mostly because we connect to bootstrap node that don't do normal operation.
