### Dev Update week 18 & 19 **1. EIP-7732 Spec Tests** I sought clarification on the availability of spec tests for EIP-7732. The discussion around the testing strategy highlighted several key points: - No specific spec tests for EIP-7732 have been written yet, as the focus has been on getting existing spec tests to pass for CI/CD purposes. - Terence clarified that the creation of new spec tests will likely happen once we reach devnet milestones, which involve client interoperability rather than formal devnets. - There is hesitation to invest effort in creating new spec tests for forkchoice rule changes until there's more certainty around the final feature set, given the ongoing discussions about potential dramatic changes in the forkchoice rule and payment system. **2. Path to Devnet Implementation** I sought advice on steps to get an implementation ready for a devnet: - The main task will be to build a Docker image of the current working branch and running it on Kurtosis. - Engaging with EthPandaOps team to create an image for EPBS was suggested - Kurtosis would then be used to form a local devnet with compatible client images. I will follow up with the EPBS public channel to sync on the approach and plan to join more breakout sessions for additional guidance. **3. Forkchoice Rule Work** I have started working on the forkchoice rule based on the [current spec](https://github.com/ethereum/consensus-specs/blob/v1.5.0-alpha.4/specs/_features/eip7732/fork-choice.md). The aim is to finish the implementation within 3 days, after which I will consider any necessary improvements based on the evolving discussion around spec changes. **4. PR** A [small PR](https://github.com/status-im/nimbus-eth2/pull/6663) I opened and got merged fixes a comment to reflect the correct validator balance count transition. While this change is small, it helps prevent confusion for anyone reviewing the code. ### Next Steps - Continue with the forkchoice implementation and review once done. - Reach out to PandaOps for assistance with Docker image creation and devnet setup. - Join EPBS breakout sessions to stay updated and aligned with ongoing efforts for EIP-7732.
