How to setup a multi-client ethereum Eth1-Eth2 merge testnet

Overview

Mergenet tutorial

Let's set up a local eth1-eth2 merge testnet!

Preparing the setup environment

In this tutorial, we use a series of scripts to generate configuration files, and these scripts have dependencies that we need to install. You can either install these dependencies on your host or you can run those scripts inside a docker container. We call this environment setupenv.

Preparing the setup environment on your host:

apt-get install python3-dev python3-pip python3-venv golang

# Check that you have Go 1.16+ installed
go version

# Create, start and install python venv
python -m venv venv 
. venv/bin/activate
pip install -r requirements.txt

# Install eth2-testnet-genesis tool (Go 1.16+ required)
go install github.com/protolambda/[email protected]
# Install eth2-val-tools
go install github.com/protolambda/[email protected]
# You are now in the right directory to run the setupenv commands below.

Alternatively, you can use docker:

docker build -t setupenv .
docker run -i -v $PWD:/mergenet-tutorial \
  -v /etc/passwd:/etc/passwd -h setupenv \
  -u $(id -u):$(id -g) -t setupenv \
  /bin/bash
# docker spawns a shell and inside that run:
cd /mergenet-tutorial
# You are now in the right directory to run the setupenv commands below.

Create chain configurations

Set eth1_genesis_timestamp inside mergenet.yamlto the current timestamp or a timestamp in the future. To use the current timestamp run:

sed -i -e s/GENESIS_TIMESTAMP/$(date +%s)/ mergenet.yaml

Otherwise tweak mergenet.yaml as you like. The current default is to have the Eth2 genesis 10 minutes after the Eth1 genesis.

"$TESTNET_NAME/public/eth1_config.json" # Configure Eth2 chain python generate_eth2_conf.py > "$TESTNET_NAME/public/eth2_config.yaml" ">
# Inside your setupenv: Generate ETH1/ETH2 configs
export TESTNET_NAME="mynetwork"
mkdir -p "$TESTNET_NAME/public" "$TESTNET_NAME/private"
# Configure Eth1 chain
python generate_eth1_conf.py > "$TESTNET_NAME/public/eth1_config.json"
# Configure Eth2 chain
python generate_eth2_conf.py > "$TESTNET_NAME/public/eth2_config.yaml"

Configure tranche(s) of validators, edit genesis_validators.yaml. Note: defaults test-purpose mnemonic and configuration is included already, no need to edit for minimal local setup. Make sure that total of count entries is more than the configured MIN_GENESIS_ACTIVE_VALIDATOR_COUNT (eth2 config).

Prepare Eth2 data

# Inside your setupenv: Generate Genesis Beacon State
eth2-testnet-genesis merge \
  --eth1-config "$TESTNET_NAME/public/eth1_config.json" \
  --eth2-config "$TESTNET_NAME/public/eth2_config.yaml" \
  --mnemonics genesis_validators.yaml \
  --state-output "$TESTNET_NAME/public/genesis.ssz" \
  --tranches-dir "$TESTNET_NAME/private/tranches"

# Build validator keystore for nodes
#
# Prysm likes to consume bundled keystores. Use `--prysm-pass` to encrypt the bundled version.
# For the other eth2 clients, a different secret is generated per validator keystore.
#
# You can change the range of validator accounts, to split keys between nodes.
# The mnemonic and key-range should match that of a tranche of validators in the beacon-state genesis.
export VALIDATOR_NODE_NAME="valclient0"
eth2-val-tools keystores \
  --out-loc "$TESTNET_NAME/private/$VALIDATOR_NODE_NAME" \
  --prysm-pass="foobar" \
  --source-min=0 \
  --source-max=64 \
  --source-mnemonic="lumber kind orange gold firm achieve tree robust peasant april very word ordinary before treat way ivory jazz cereal debate juice evil flame sadness"

Start nodes

This documents how to build the binaries from source, so you can make changes and check out experimental git branches. It's possible to build docker images (or use pre-built ones) as well. Ask the client devs for alternative install instructions.

mkdir clients

mkdir "$TESTNET_NAME/nodes"

You can choose to run clients in two ways:

The docker instructions include how to configure each of the clients. Substitute docker volume-mounts with your own directory layout choices, the instructions are otherwise the same.

Genesis

Now wait for the genesis of the chain! actual_genesis_timestamp = eth1_genesis_timestamp + eth2_genesis_delay

Bonus

Test ETH transaction

Import a pre-mined account into some web3 wallet (e.g. metamask), connect to local RPC, and send a transaction with a GUI.

Run example_transaction.py.
