# Week 3 Hi everyone, Rupam this side. This week was mostly spent in trying to run a node on the Holesky testnet using Geth and Prysm light client. This was done to check if the already implemented light client features are working as intended or not (which they weren't unfortunately). I also have been learning Go side by side and trying to get myself familiar to Prysm's codebase. ## What's Next? From what it looks like, even though light client tests are passing successfully in Prysm, there seems to be some error either in the implementation or tests. As said by [Radek](https://github.com/rkapka) we have to debug the code and see where its going wrong. Also [Bastin](https://github.com/Inspector-Butters) made an amazing [doc](https://hackmd.io/@Bastin/HyKnoHh8R) on what possible changes we will need to put forward to make the light client production ready. At the time of writing this, Radek is yet to review the doc and once we get the signal we will probably be moving forward with the programming part. Other than that, as I said before I've been learning Go, mainly from their official docs to get started and have also been going through Prysm by comparing it to CL specs to understand how things are working over there. ## Some References * https://github.com/prysmaticlabs/prysm/pull/12853 * https://github.com/prysmaticlabs/prysm/pull/12984 * https://github.com/prysmaticlabs/prysm/pull/13225 * https://github.com/ethereum/consensus-specs/tree/208da34ac4e75337baf79adebf036ab595e39f15/specs/altair/light-client * https://github.com/ethereum/beacon-APIs * https://github.com/prysmaticlabs/prysm/pull/13588
