- last 2 weeks went into trying to implement custom `crit` log, as `tracing` doesn't have a `crit` log level out of the box like `slog` and it also doesn't support defining custom levels.

- here's the [commit](https://github.com/sigp/lighthouse/pull/6070/commits/125a1056d8fdffd4ea3cd5580aab4b19fd49e64c) (there's still some work left to do in lighthouse's formatter)
- along with that ,I've been working on abstracting ExecutionLayer backend for lighthouse-reth,will open the PR in 1-2 days

### Resources
- [The Little Book of Rust Macros](https://veykril.github.io/tlborm/introduction.html)
### Goals for next week
- Get the `crit` log fully implemented
- Get the ExecutionLayer backend abstraction PR ready
