DAS prototype devnet setup

README.md

DAS Prototype Devnet

A local devnet for running the DAS prototype from the das Lighthouse branch.

This configuration runs 2 "super" nodes and 2 regular nodes (subscribes to 1 column subnets). It also spams transactions and blobs to the network, so we can see blob columns getting published and received by peers. PeerDAS is activated from epoch 3.

Metrics are available on Grafana dashboard.

Prerequisites

• Docker installed
• Kurtosis installed: https://docs.kurtosis.com/install/#ii-install-the-cli

For MacOS

brew install kurtosis-tech/tap/kurtosis-cli

Building the Lighthouse Image

From the das branch, run the following command

docker build --build-arg FEATURES=portable -t lighthouse:das . 

Start

Run the following comand to start a local devnet using the network params from this gist:

kurtosis run --enclave das-devnet github.com/kurtosis-tech/ethereum-package --args-file 
https://gist.githubusercontent.com/jimmygchen/54574443ea8a94118f0f748b69a5e610/raw/a219867d8b470a67cb4874ccd147899c5281c2ca/network_params.yaml

Alternatively, if you'd like to modify the network params, copy the network_params.yaml file below to current working directory and run:

kurtosis run --enclave das-devnet \
  github.com/kurtosis-tech/ethereum-package \
  "$(cat ./network_params.yaml)"

Inspect / List services

Kurtosis runs the nodes in Docker, and the containers can be inspected directly using the docker command.

To inspect them with Kurtosis, run:

kurtosis enclave inspect das-devnet

or via a GUI:

kurtosis web

Stop

kurtosis enclave rm -f das-devnet

Shell

kurtosis service shell das-devnet $SERVICE_NAME

Logs

kurtosis service logs das-devnet $SERVICE_NAME
