dummy_builder

World's dumbest block builder for Ethereum.

This is a block builder designed with very specific goals, it aims to:

  • Return a payload header as quickly as possible.
  • Satisfy all consensus client safety checks on the payload header, e.g. correct randao, withdrawals, bid value, etc.
  • Minimise dependencies and implementation complexity (depends on Lighthouse but not mev-rs).

Non-goals:

  • Creating valid payload bodies (!!). Unblinding the headers is not implemented.

It is designed for use in the blockprint ecosystem where we want a fleet of CL nodes to build a block as quickly as possible with no concern for execution payload validity or quality.
