Running a Mainnet 0 Node

This page provides the specific configuration used to run different types of nodes in Mainnet 0.

Note: during Mainnet 0 only a fixed set of preregistered operators can run a node. The Espresso Network will upgrade to proof-of-stake in a later release.

🫵 TL;DR: For operator running Decaf nodes, the critical changes from that configuration are as follows:

• All URLs supplied by Espresso have changed

• The new container image version is 20241120-patch5

• The JSON-RPC endpoint specified by ESPRESSO_SEQUENCER_L1_PROVIDER should be an Ethereum mainnet endpoint instead of Sepolia

The container image to use for this deployment is

• ghcr.io/espressosystems/espresso-sequencer/sequencer:20241120-patch5 (if using Espresso's images)

• built off of the branch `20241120-patch5` (if building from source)

The configuration for all node types includes ESPRESSO_SEQUENCER_GENESIS_FILE=/genesis/mainnet.toml. This file is built into the official Docker images. Operators building their own images will need to ensure this file is included and their nodes are pointed at it.

1. Regular Node

Command

sequencer -- http -- catchup -- status

Environment

Same for all nodes

RUST_LOG="warn,libp2p=off"
RUST_LOG_FORMAT="json"
# At least one state peer is required. The following URL provided by Espresso works.
# Optionally, add endpoints for additional peers, separated by commas.
ESPRESSO_SEQUENCER_STATE_PEERS=https://query.main.net.espresso.network

Chosen by operators

# JSON-RPC endpoint for Ethereum Mainnet
ESPRESSO_SEQUENCER_L1_PROVIDER # e.g. https://mainnet.infura.io/v3/<API-KEY>
# Port on which to host metrics and healthchecks
ESPRESSO_SEQUENCER_API_PORT # e.g. 80
# Path in container to store consensus state
ESPRESSO_SEQUENCER_STORAGE_PATH # e.g. /mount/sequencer/store/
# Path in container to keystore
ESPRESSO_SEQUENCER_KEY_FILE # e.g. /mount/sequencer/keys/0.env
# The address to bind Libp2p to in host:port form. Other nodes should be able to
# access this; i.e. port must be open for UDP.
ESPRESSO_SEQUENCER_LIBP2P_BIND_ADDRESS
# The address we should advertise to other nodes as being our Libp2p endpoint
# (in host:port form). It should resolve a connection to the above bind address; i.e.
# should use public IP address or hostname, and forward to the port given in the bind
# address.
