# EPF5 Week-4: Kurtosis PeerDAS

## Week overview
- [X] Learned how to work with Kurtosis
- [X] Ran Kurtosis PeerDAS testnet
- [X] Installed Teku, ran testnet network
- [X] Installed Grafana
- [X] Watched EPF Study Group Week 9 video
- [X] Explored Dora

This week was focused on running Kurtosis PeerDAS. I began with the Quickstart guide and then gradually progressed to configuring it with PeerDAS parameters. Despite encountering various issues along the way, I managed to get everything working. During this process, I gained experience in managing Kurtosis enclaves, modifying the Kurtosis configuration YAML file, and operating Dora.

Additionally, I started exploring Consensus Clients, beginning with Teku due to its active involvement in PeerDAS testing. I set up its testnet network and utilized Grafana for monitoring.

## Running Kurtosis
You can find an installation guide [here](https://docs.kurtosis.com/install). While working with Kurtosis, don't forget to start Docker.

Kurtosis engine commands:

kurtosis engine start
kurtosis engine stop
kurtosis engine restart
kurtosis engine status

Inintial running:

kurtosis run github.com/ethpandaops/ethereum-package

Running an enclave with my args:

kurtosis run --enclave my-testnet github.com/ethpandaops/ethereum-package --args-file peerdas_params.yaml


Working with enclaves:

kurtosis enclave ls
kurtosis enclave inspect my-testnet
kurtosis enclave stop my-testnet
kurtosis enclave rm my-testnet
kurtosis clean -a

## Kurtosis PeerDAS network params
Here are my latest params for `network_params.yaml` file:

## PeerDAS on Clients

| Client |Repo |
| -------- | -------- |
| Teku | [DAS branch](https://github.com/Nashatyrev/teku/tree/das) |

## Dora
[Dora the Explorer](https://github.com/ethpandaops/dora) is a lightweight beaconchain explorer. A Beaconchain explorer is a tool that allows users to view and interact with the data on the Ethereum Beacon Chain. It is similar to a blockchain explorer, which allows users to view data on a blockchain such as the current state of transactions and blocks - but focussed on exploring the beaconchain.

You can use Dora for the local devnets when running your enclave:

Here is a Dora representation of my local devnet running:

## Teku progress
I downloaded the PeerDAS version of Teku. Attempted to build a Docker image but encountered an error on my Mac. Successfully ran the Teku testnet network locally. Reviewed the Teku dashboard on Grafana.
