# Week 7 ## Summary Very short week in term of work, nothing was conluent regarding the optimistic sync enhancement tests; I did try to implement [the test case proposed by potuz](https://github.com/ethereum/consensus-spec-tests/issues/30) but I can't find a way to make it works. Maybe I miss understoos something but when I add C while keeping B as the optimisitc head, it switchs to C... wnad do'nt want this. I will find a way but I need time to figure why it behaves like that. ## Ressources - [PR '✅ Add optimistic sync tests'](https://github.com/ethereum/consensus-specs/pull/3489) - [Issue 'Add more optimistic sync tests'](https://github.com/ethereum/consensus-spec-tests/issues/30) ## Activity - [Refactor '✅ Add optimistic sync tests'](https://github.com/ethereum/consensus-specs/pull/3489)
