When the BN-embedded LC makes sync progress, pass the corresponding execution block hash to the EL via `engine_forkchoiceUpdatedV1`. This allows the EL to sync to wall slot while the chain DAG is behind. Renamed `--light-client` to `--sync-light-client` for clarity, and `--light-client-trusted-block-root` to `--trusted-block-root` for consistency with `nimbus_light_client`. Note that this does not work well in practice at this time: - Geth sticks to the optimistic sync: "Ignoring payload while snap syncing" (when passing the LC head) "Forkchoice requested unknown head" (when updating to LC head) - Nethermind syncs to LC head but does not report ancestors as VALID, so the main forward sync is still stuck in optimistic mode: "Pre-pivot block, ignored and returned Syncing" To aid EL client teams in fixing those issues, having this available as a hidden option is still useful.
The Nimbus Guide is written using markdown and material for mkdocs.
See the Makefile
for setup.
The guide is divided into several sections - broadly:
- Guides - walk-throughs that allow the user to get started with a specific area of the client
- How-to:s - short pages that show the user how to solve a specific problem or perform a specific task
- Reference - pages describing how specific parts of Nimbus work, reference-style
- "Other" - explanations of concepts, background etc.
