Implementation of the next release of Zerokit
Description
This commitment entails achieving Zerokit v0.7.0 by advancing the next version through the integration of new features aimed at improving its speed and robustness, such as Poseidon integration, accelerated witness generation, and updates to the WASM module.
Background
Zerokit is a collection of Zero Knowledge modules that focus on RLN, developed in Rust, intended for integration with various system programming environments.
This commitment marks the next iteration of Zerokit addressed by the issue https://github.com/vacp2p/zerokit/issues/263, version 0.7.0, which introduces several new features, including arkzkey, poseidon and updated wasm that is distinguishing it from the previous version.
Narratives
By utilizing the zerokit-v0-7 commitment, we will reinforce the Conduit of Expertise narrative by:
We will also strengthen the Premier Research Destination narrative by:
- Offers a Rust crate that serves as a more efficient open-source development tool for users looking to integrate RLN into their projects.

Description
Regarding the issue 271, rln wasm is revisited for performance analysis and updated by dependencies and gatherin new benchmarks.
Deliverables
- PR to vacp2p/zerokit repo with related update for v0.7
Bump dependencies

- status: done
- start-date: 2025/01/27
- end-date: 2025/02/07
Description
zerokit fixes many dependencies and some versions are too old
and new libraries don’t support them and a conflict happened.
One of this dependency is num_traits cannot be fixed yet
because this strict dependency came from ark-zkey,
and there it in turn came from a fork on an old version of arc-circom where version 2.15 is fixed.
Deliverables
A PR to the zerokit repository.
RLN-cli

Description
The rln-cli is a command-line utility designed to help developers integrate Rate-Limiting Nullifier (RLN) into their applications. However, it is currently unusable due to a missing configuration file. To enable its functionality, the codebase needs to be improved to properly handle the required configuration.
Additionally, the RLN-cli task contains implementing an example demonstrating RLN’s stateless mode. This involves creating the Merkle tree outside of RLN, similar to the approach used here. The example should then provide the necessary roots from tree to RLN functions. This will help developers better understand RLN’s functionality and how to integrate it in a stateless manner.
Deliverables
A PR to the Zerokit repository that contains as follows:
-
Fix Configuration Handling:
- Document the expected format of the configuration file.
- Provide an example configuration file in
rln-clito guide users. - Ensure that the CLI provides useful error messages if the configuration is missing or incorrect.
-
Implement Stateless RLN Example:
- Create an example where the Merkle tree is constructed outside of RLN (similar to this test).
- Use this external tree to generate path and roots, then pass them into RLN functions.
-
Testing & Documentation:
- Add tests to verify the CLI works correctly with the new configuration handling.
- Ensure the new stateless example is well-documented so that developers can easily follow it
