## EPF5 Dev Updates - Week 14 [◀️ *previous update*](https://hackmd.io/@hangleang/epf5-week13) ### Goals For This Week - [x] check node out of sync, and not build on prev. slot problems - [ ] prepare rebase on `electra` ### Activities - add batch publish on data column sidecars in this [commit](https://github.com/hangleang/grandine/commit/86171fb6aeeed2383488a3d46ed8181eba1d1509) to reduce network overload, need to reduce the spamming publish on others topics as well (e.g. sync commitee message, signed contribution and proofs, etc) which cause the duplicate messages - add data availability check for subnet sampling on full node in this [commit](https://github.com/hangleang/grandine/commit/5fcaea59020f984c7272963678188fbc17e5327a), so Grandine full node can sync with other clients - currently, Grandine can only sync with others when disabling peer scoring. there is a known bug when try to enable peer scoring, which cause peer to disconnect and remove each other. this is my [write-up](https://hackmd.io/@hangleang/HyUqFL-pA) on investigating the problem, need to spend next week debug on that further. ### Plan For Next Week - dubug on peer disconnect issue - reduce network overload on duplicate messages --- [▶️ *next update*](https://hackmd.io/@hangleang/epf5-week15)
