Based on https://github.com/rolfyone/playground/tree/main/capella/beku (which is based on https://github.com/ajsutton/merge-scripts/tree/main/beku)
Use whichever besu and teku branch you want to test, build besu and teku respectively with ./gradlew installDist
Set 2 environment variables, to find besu and teku binaries. These are the locations of the applications that will be run in the start scripts.
export BESU=$HOME/IdeaProjects/besu/build/install/besu/bin/besu
export TEKU=$HOME/IdeaProjects/teku/build/install/teku/bin/teku
Run the startBesu.sh script to start the besu instance for the network.
There is a debugBesu.sh to enable debug mode.
Run the startTeku.sh script.
Run cleanup.sh to clean artifacts of these scripts. besu and teku should not be running while this script is run.
- Besu starts with all forks including shanghaiTime at 0.
- CL Starts with all forks including Capella at 0.
- If you change any part of the genesis block, then you must run besu, get the modified genesis block hash and update genesis-header.json with it
- genesis-header.json in teku interop mode let's teku know what the besu's genesis hash is so it doesn't try to request it as if the merge transition has happened.
- If you change shanghaiTime to be non-zero, then this will also affect the genesis block hash since withdrawalsRoot will no longer be part of it, so need to update genesis-header.json with the new hash.
