## Issue Addressed Lighthouse gossiping late messages ## Proposed Changes Point LH to our fork using tokio interval, which 1) works as expected 2) is more performant than the previous version that actually worked as expected Upgrade libp2p ## Additional Info https://github.com/libp2p/rust-libp2p/issues/2497

// using `lighthouse_metrics::gather(..)` to collect the global `DEFAULT_REGISTRY` metrics into
|
|
// a string that can be returned via HTTP.
