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 20240925-patch3
The JSON-RPC endpoint specified by ESPRESSO_SEQUENCER_L1_PROVIDER should be an Ethereum mainnet endpoint instead of Sepolia
built off of the branch 20240925-patch3 (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.
