This folder contains scripts for launching the nimbus beacon chain node in a configuration appropriate for [interop](https://github.com/ethereum/eth2.0-pm/tree/master/interop).
|
|
|
|
## Building
|
|
|
|
In general, follow the build instructions of `nim-beacon-chain` as documented in the main repo - make sure to set up your build environment with all necessary system libraries as documented there:
|
|
|
|
```bash
|
|
# Clone repo
|
|
|
|
export GIT_LFS_SKIP_SMUDGE=1 # skip LFS
|
|
git clone https://github.com/status-im/nim-beacon-chain.git
|
|
|
|
cd nim-beacon-chain
|
|
|
|
make # prepare build system (cloning the correct submodules)
|
|
make update deps # build dependencies
|
|
```
|
|
|
|
## Running
|
|
|
|
Look in the scripts for options - the default config is a small setup using the `minimal` state spec.
|
|
|
|
```
|
|
cd interop
|
|
|
|
# Clear data from previous run, then start a new simulation
|
|
rm -rf data; ./start.sh
|
|
|
|
# In a separate terminal, can run another beacon node, such as lighthouse:
|
|
./run_lighthouse.sh
|
|
```
|
|
|
|
## Diagnostics
|
|
|
|
```bash
|
|
# Nimbus genesis state
|
|
less data/state_snapshot.json
|
|
|
|
# Lighthouse genesis state
|
|
curl localhost:5052/beacon/state?slot=0 | python -m json.tool | sed 's/"0x/"/' > /tmp/lighthouse_state.json
|
|
|
|
# Format nimbus the same
|
|
cat data/state_snapshot.json | python -m json.tool | sed 's/"0x/"/' > /tmp/nimbus_state.json
|
|
|
|
diff -uw /tmp/nimbus_state.json /tmp/lighthouse_state.json
|
|
```
