Binary Nimbus beacon node distribution

This binary distribution of the Nimbus eth2 package is compiled in reproducible way from source files hosted at https://github.com/status-im/nimbus-eth2.

The tarball containing this README uses the following naming scheme:

nimbus-eth2_<TARGET OS>_<TARGET CPU>_<VERSION>_<GIT COMMIT>.tar.gz

For a more complete and up-to-date documentation, please refer to the Nimbus book.

Reproducing the build

Besides the generic build requirements, you also need Docker.

git clone https://github.com/status-im/nimbus-eth2.git
cd nimbus-eth2
git checkout GIT_COMMIT
make update
make dist

Significant differences from self-built binaries

No -march=native and no metrics support.

Running a Medalla node

With default options:

./run-medalla-beacon-node.sh

The script will forward all supplied options to the beacon node executable:

./run-medalla-beacon-node.sh --log-level=DEBUG --tcp-port=9050

To monitor the Eth1 validator deposit contract, you'll need to pair the Nimbus beacon node with a Web3 provider capable of serving Eth1 event logs. This could be a locally running Eth1 client such as Geth or a cloud service such as Infura. For more information please see our setup guides:

https://status-im.github.io/nimbus-eth2/eth1.html

By default, the script will ask you to enter a web3 provider URL interactively, but this can be bypassed by specifying a websocket WEB3_URL environment variable:

WEB3_URL="<YOUR_WEB3_URL>" ./run-medalla-beacon-node.sh

Running a mainnet node

run-mainnet-beacon-node.sh is a similar script intended for connecting to mainnet. All the same conventions apply:

# using a local Geth instance
WEB3_URL="ws://localhost:8545" ./run-mainnet-node.sh --max-peers=150
