Lodestar v2.0 Roadmap

[philknows]

This issue is to compile milestones we would like to achieve to consider ourselves v2.0 ready. The general goal of major bumping Lodestar is to signify our client's ability to match and/or exceed metrics such as profitability/performance to a competitive degree.

*Subject to change, issue will be regularly updated to reflect new/modified milestones

Goals

• Improve block arrival times / Reduce latency
  • Based on data by ProbeLab: https://ethresear.ch/t/gossipsub-message-propagation-latency/19982 , https://probelab.io/ethereum/block_arrival/2024-29/
• Backfill Sync

Issues/PRs

• SSZ Batch hashing: feat: consume new ssz batch hash branch #6939
• Binary state diffs: feat: use binary diff to persist finalized states #7005

Other Tasks

• List deprecated CLI flags and remove

yes #7005 should be on v2 where we move to new database repositories, a node will not work without checkpoint sync url since we don't go with StateArchiveRepository anymore

[twoeths]

the block arrival time is actually block time to head, our metrics are not the same to ProbeLab, created the issue in #7046

Some other notes I found from previous discussions to potentially decide for adding to this milestone:

• Archive mode with configurability to store on disk?
• Supporting multiple transports for browser usage? Add browser-compatible transports #6975
• Polishing goals. See:
  • https://github.com/ChainSafe/lodestar/issues?q=is%3Aopen+is%3Aissue+label%3Ascope-logging
  • https://github.com/ChainSafe/lodestar/issues?q=is%3Aissue+is%3Aopen+label%3Ascope-metrics

I think validator performance when subscribing to all subnets should be included in lodestar 2.0 roadmap too
