• Implementation plan

• Study the solidity code

• setup the SemaphoreGroups function interaces traits

• define the contract state base the memory state from the solidity contract

• implement the function

• send a draft PR

• Implement changes base on the PR review

hi , im from dojo coding, I can take this issue, is only convert to soroban env :) for be honest I don't know about soroban coding languages but I can learn about that

Hi!, my name is Joseph Poveda. I am a student of the Systems Programming degree, I am a recent member of the Dojo Coding community, where I am getting started in the world of Web3. I have basic knowledge of different programming languages ​​and thanks to this I hope to be able to resolve the issue. To migrate the Semaphore Groups contract to Soroban, follow these steps:

Analyze the Original Contract: Review the functionalities in SemaphoreGroups.sol and ISemaphoreGroups.sol from the provided links, understanding group management, permissions, and events in Ethereum.

Get Familiar with Soroban: Learn Soroban's SDK and libraries, as its syntax and features may differ from Ethereum.

Port the Code: Adapt the group creation and management functionalities to Soroban, keeping its unique structure in mind.

Testing: Develop unit tests in Soroban to ensure the migrated contract works as expected.

I'd like to take this issue.

1. Key Components:

• Base Contract: SemaphoreGroups.sol
• Interface: ISemaphoreGroups.sol

1. Main Functions to Migrate:

• Create groups
• Update group parameters
• Group member management (add/remove)
• Group verification logic

3. Technical Requirements:

• Convert Solidity code to Rust
• Implement Soroban contract interface
• Maintain group trees functionality
• Keep zero-knowledge proof verification

Hi @bitfalt @evgongora,

I’m applying for this issue via the OnlyDust platform.

Background and Relevant Experience

My name is Koxy, a blockchain Rust developer and Stellar ecosystem contributor. I’m the creator of the YouTube series Let’s Get Soroban, where I delve into hands-on development with Rust and the Stellar platform.

With a strong background in open-source development and a deep familiarity with Stellar’s architecture, I’m well-positioned to undertake the migration of the Semaphore Groups contract to Soroban.

I’m excited to implement immediate solutions and collaborate with the team on long-term improvements to enhance the Semaphore protocol.

Approach to Tackling This Issue

To address this migration, I plan to:

1. Implement a Trait for SemaphoreGroups: Develop a trait and implement it to create a compatible contract for the Soroban platform.

2. Thorough Testing: Write comprehensive tests that cover a wide range of scenarios, including edge cases. As i proposed here.

3. Update Documentation: Revise CLI documentation and help messages to reflect the changes accurately.

4. Submit PR: Create a detailed pull request with explanations of the changes and their rationale.

5. Collaborate and Iterate: Work closely with maintainers to incorporate feedback and refine the solution as necessary.

This is a sample contract written in soroban.
