INIT: Multi Node (Validator) Testnet

[julienrbrt]

Summary

This bounty seeks a developer to implement a multi-node testnet feature for Ignite CLI. The goal is to extend the existing ignite testnet command with a new ignite testnet multi-nodes subcommand, allowing developers to easily set up and manage multiple validator nodes for testing purposes.

Description

We propose extending the Ignite CLI with a multi-node testnet feature, enhancing the testing capabilities for Cosmos SDK-based blockchain applications. This feature will allow developers to create and manage multiple validator nodes, observe their behavior, and simulate various network conditions. A bounty of $3000 will be awarded to the developer completing this issue.

Requirements

1. Extend the ignite testnet command with a new ignite testnet multi-node subcommand.
2. Implement a new multi-node section in the config.yaml file to specify validator configurations.
3. Create an interactive screen using the charmbracelet/bubbletea library to display logs from multiple validators simultaneously.
4. Implement functionality to dynamically kill and restart nodes to observe chain performance.
5. Ensure compatibility with existing Ignite CLI features and workflows.
6. (bonus) Add the ability for nodes to join the network after initial setup.

Detailed Specifications

Config.yaml Integration:

• Use the existing validators section from the config.yaml file.
• Allow users to specify the number of validators and their configurations.
• Provide options for random validator generation if specific configurations are not provided via flag.

Example config.yaml structure:

...
 validators:
    - name: validator1
      stake: 100000000stake
    - name: validator2
      stake: 200000000stake

Interactive UI:

• Implement an interactive UI using the charmbracelet/bubbletea library.
• Display real-time logs from all active validator nodes.
• Provide options to toggle between different views (e.g., all nodes, specific node, network statistics).

Node Management:

• Implement UI options (or subcommand) to kill and restart specific nodes.
• Add functionality to introduce new nodes to the network after initial setup.
• Provide clear feedback on network state and node status changes.

Integration with Ignite CLI:

• Ensure the new feature works seamlessly with existing Ignite CLI commands and workflows.
• Maintain consistency with Ignite CLI's code style and best practices.

Evaluation Criteria

• Functionality: The implementation should meet all specified requirements and work reliably.
• User Experience: The interactive UI should be intuitive and provide valuable insights into the multi-node testnet.
• Code Quality: The code should be well-structured, documented, and follow Ignite CLI coding conventions.
• Testing: Comprehensive tests should be included to ensure feature reliability.
• Documentation: Clear and concise documentation on how to use the new feature should be provided.

Implementation

This list is not exhaustive:

• Create a new command in ignite/cmd/testnet_multi_node.go
• Extend the chain config (config.yaml) in ignite/config/chain/v1
  • Add in default some dummy validators so that the command always works on new scaffold
• Add testnet code to chain templates (*.plush files), following the best practice from the Cosmos SDK Simapp, but keep it extensible via Ignite
  • Probably add helpers in ignite/pkg/chaincmd to integrate with the node command

Additional Resources

• Ignite CLI GitHub repository: https://github.com/ignite/cli
• Cosmos SDK testnet implementation: https://github.com/cosmos/cosmos-sdk/blob/main/simapp/simd/cmd/testnet.go
• charmbracelet/bubbletea library: https://github.com/charmbracelet/bubbletea
• Slightly differs from https://github.com/ignite/cli/issues/2473 but still related

Notes

• This issue is open to all developers with the necessary skills and experience.
• The Ignite development team will be available to answer questions and provide support throughout the development process.
• We encourage developers to submit clear proposals outlining their approach and estimated timeline.
• The bounty reward is $3000. An additional reward may be granted if all bonus tasks have been completed.

I'll like to start working on this issue

[likesToEatFish]

I have some relevant experience with this and would really like to take it on. If you're okay with it, I’d love to work on this. If you'd like, we could collaborate on it as well. @julienrbrt

[julienrbrt]

Hey you are both welcome to give it a go!

[Pantani]

IMHO, instead of changing the config file and avoid to have the v3, we can use the current structure; instead of adding everything below the multi-node, we can put everything inside the validators key, which was made for it. like the issue #2473

The issue of doing this, is that it makes it unclear between chain serve and multi-node. The different would be, chain serve runs the first one and multi node all of them?

Additionally, this is less breaking to add fields than rename them.

[julienrbrt]

After our call, you are right, validators exists already, so best to use it instead. I have updated the issue description.
