# Week 9 & 10 Update

I completed the [Era Reading pr](https://github.com/ChainSafe/lodestar/pull/8035) and I am waiting for caymen to review it.
I also added an integration tests where we are checking the some entries of the era file such as `Version`, `block payload`, `state slotIndex` . The isssue with this is we cannot wait for the Ci/CD to download the 500mb era file so after talking to my mentor I skipped it for CI/CD by adding in `describe.runIf(!process.env.CI)`. I also modified the bash script [to download era files](https://hackmd.io/@advaita/BkMvD9Qllg#%F0%9F%93%9C-The-Script-Save-as-download_erash) to download that exact era file I need from my tests.

I joined the Lodestar Core Dev call too and they are are seemingly going for a hybrid node/js and bun approach to unlock the zig magic , aka use the bun ffi to plug in their zig modules.
