BAL Benchmarking Instructions

Geth Branch: https://github.com/jwasinger/go-ethereum/tree/bal-execution

  1. Download a post-Cancun state snapshot (https://ethpandaops.io/data/snapshots/) and unzip the snapshot into the directory where you will have your datadir.

  2. Full-sync as many blocks as you want, building the BALs for them (enable the --experimentalbal flag)

  3. Use geth export to extract the blocks (with BALs embedded).

  4. Reset the datadir back to the snapshot block (or just delete it, unpack the snapshot archive back to that target location).
