Cappuccino node operators are limited to a select group. If you are interested in running a node in a future release of Espresso, contact us.
This page give the configuration used to run different types of nodes in the Cappuccino testnet. For general information on running an Espresso node, see Running an Espresso Node.
All nodes in Cappuccino use the ghcr.io/espressosystems/espresso-sequencer/sequencer:cappuccino Docker image. Depending on the type of node, the configuration varies.
