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 ```
