# How to run Catalyst
|
|
|
|
- Clone Geth: `git clone --branch kintsugi-spec https://github.com/MariusVanDerWijden/go-ethereum.git ~/execution_clients/go-ethereum
|
|
- Build Geth and Catalyst with `make geth`
|
|
- Run `scripts/run-catalyst.sh` to run Catalyst. It listens on port 8545.
|
|
|
|
# Verify Catalyst is working
|
|
|
|
- Clone Nimbus and check out the `kintsugi` branch
|
|
- Run `scripts/run-catalyst.sh`. This depends on the paths set up in the first section. If those are changed, adjust accordingly.
|
|
- While the Geth console is running, run `scripts/check_merge_test_vectors.sh`.
|
|
|
|
The results should be similar to
|
|
```

kintsugi test vectors passed
|
|
```
|
|
|
|
- If issues present themselves here, or when Nimbus attempts to use the API, one can `debug.verbosity(4)` console command in Catalyst.
|
|
|
|
# Verify that Nimbus runs through the same examples
|
|
|
|
- Run `./env.sh nim c -r tests/test_merge_vectors.nim`. It should show output akin to:
|
|
|
|
```
|
|
[Suite] Merge test vectors
|
|
[OK] getPayload, executePayload, and forkchoiceUpdated

# How to run Nimbus local testnet with Catalyst
|
|
|
|
- Check out branch `kintsugi`
|
|
- Run (and keep running) `./scripts/run-catalyst.sh`. It should look something like
|
|
|
|
|
|
- Run `./scripts/launch_local_testnet.sh --preset minimal --nodes 4 --disable-htop --stop-at-epoch 7 -- --verify-finalization --discv5:no`
|
|
|
|
This creates a 4-node local testnet with 128 validators.
|
|
|
|
The Nimbus console output will be similar to

Meanwhile, Nimbus is interacting with Geth/Catalyst in preparing, getting, and executing payloads:
