## EPF5 Dev Updates - Week 7 & 8

[◀️ *previous update*](https://hackmd.io/@hangleang/epf5-week6)

*This update would be cover my progress on week 7 & 8, since I'm not feeling well in the last week 7, and have been signed off from EPF task for almost a week on week 8.*

### Goals For This Week

- [x] Debug on proposer delay and fix some issues related to it
- [x] Explore other project ideas
- [x] Request formal review from Grandine team, update on feedbacks

### Activities

- proposer delay basically not a problem, whenever I run heavily computation while running the devnet, the problem always occurred, but does not have any side effect, once my computer settle from the computation, it went back normal.
- interested in SSZ stable container proposal
- I requested the grandine team to review the PR: https://github.com/grandinetech/grandine/pull/34, but they require unless everything is working properly, so they can just scan and merge, so no feedback to updated :)
- run rounds of devnet:
- **2 supernode grandine**: work as expected
- **2 supernode lighthouse**: work as expected, just a few slot were missed
- **1 supernode grandine, 1 supernode lighthouse**: syncing problem cause by peer scoring, and rate-limiting. same with 1 non-supernode lighthouse
- **1 supernode lighthouse, 1 non-supernode grandine**: no config available in grandine, default is supernode, can not changed
- which mean, the interop between different clients impls is not success, and this is not only for grandine, some other clients pair as well. the syncing problem has been an issue since the team is implementing the PeerDAS

### Plan For Next Week

- debug more on what cause the node to disconnect
- looking into libp2p networking backport
- fix bugs if any
