Week 2 - HackMD

# Week 2 This week, I tried to dig deeper into the [Ream Client - A Beam client in Rust: Implement Beacon API Endpoints](https://github.com/eth-protocol-fellows/cohort-six/blob/master/projects/project-ideas.md#ream-client---a-beam-client-in-rust-implement-beacon-api-endpoints) project. I started by reading [Annotated Beacon Chain Specification](https://eth2book.info/capella/part3/) chapter from the [Upgrading Ethereum book](https://eth2book.info) and I used [DeepWiki](https://deepwiki.com/sigp/lighthouse) to explore [Lighthouse](https://github.com/sigp/lighthouse)'s architecture. Meanwhile, I began preparing my proposol for the EPF day. I watched last year's [EPF day presentations](https://www.youtube.com/watch?v=_KwVJm5eHZ4) as a reference, reviewed the [Beacon API Spec](https://github.com/ethereum/beacon-APIs), and explored Github issues tagged with "Beacon API". There are 70 issues: 42 closed(with merged PRs), 28 open, and only 19 unassigned. Each issue covers one endpoint of Beacon API. Some endpoints might be missing from the list, so I'll add them on GitHub once I start working. After examining some merged PRs, I noticed that some were straightforward, but many open issues are more complex, the Consensus Spec doesn't cover the implmentation details, I looked into Lighthouse's implementation, it can be quite complicatied. I also got the Ream Beacon Node running. It takes quite a while to finish a check point sync, Beacon API becomes accessible only after syncing completes. I tested some the implemented Beacon API to see how it works. Over the weekend, we arrived in Cannes. Some of us who tend to work on Ream & Beam chain related projects attended. Researchers, cryptographers, and client team representatives gathered to dissuss progress of all the experiments they're doing for Beam chain. I gained quite a lot of insights. ## Resources [Annotated Beacon Chain Specification](https://eth2book.info/capella/part3/) [Upgrading Ethereum book](https://eth2book.info) [Beacon API Spec](https://github.com/ethereum/beacon-APIs) [Lighthouse](https://github.com/sigp/lighthouse) [EPF day presentations from Cohort 5](https://www.youtube.com/watch?v=_KwVJm5eHZ4)
