# Week 11 Update

I added the code for `readBeaconStateFromEra` and `readBeaconBlockFromEra` to Reading Era Files too So that we can ready Block Data which will be needed later . I also added tests for them .
I also completed the Writing of Era Files , but lodestar is still not able to produce era Files since its not conncted to the DB.
I also found a javascript implementation of some e2store implementation in [Ethereum js](https://github.com/ethereumjs/ethereumjs-monorepo/tree/master/packages/e2store).
I was also reading about the [Bun FFI bindings for LodeStar](https://github.com/ChainSafe/lodestar-bun) that Caymen is working on. This is a bit ambitious but the Lodestar Team is also looking into a hybrid implementation of bun and Node.

I am still waiting for Caymen to review my pr on ERA file Reading.

## Work for Next Week
- Production of ERA files in Lodestar
