Finished with week 2 of **Ethereum India Fellowship’3** and I am super excited to share the progress, plan & updates in this blog.

Developer Identity System
-------------------------

The developer identity is a privacy-focused verifiable identity for developers that can be used to hold claims / certificates for their achievements & activities. This includes:

*   Participating or Winning at a Hackathon
    
*   Doing a new course / tutorial
    
*   Finishing a internship
    
*   Receiving grants & completion badges
    
*   DAO contributions
    
*   On-chain reputation, etc.
    

If you would like to know more about why this is important or what is Ethereum India Fellowship, I would recommend you reading my first week’s article:

Second Week (13th to 17th Feb 2023)
-----------------------------------

This week I planned out the working & idea of how identity system should work, and here it is:

1.  Developer Identity will have 2 parts i.e. Public profile & Private profile.
    
2.  Public profile basically represents the data available on-chain about the developer activities like opensource contributions, personal details, social connections, SBTs, POAPs etc.
    
3.  The public profile should be controlled by the private-key holder, having access to private claims received on the device. To improve UX at scale, this will be in form of a mobile application.
    
4.  The purpose of private profile is to manage the public profile and hold **Verified Credentials**. These VCs are held off-chain on the mobile device using PolygonID wallet technology integrated.
    
5.  Developer can use both public & private data to validate / prove the authenticity at any point without the need to disclose all the information to everyone.

Integration Flow

So, this week a couple of things happened:

*   On 16th Feb, Polygon ID team released new version of their software and now opensource everything that is necessary to build a prototype.
    
*   Started with the public page for developer profile, the purpose is to onboard and show data that is verified.

*   Implemented the biconomy SDK for smooth login & gasless user registry.
    
*   Getting contributions data on-chain & the graph is verified as it is coming from Sadaiv CI’s github contribution backup contract.
    

> On Friday, I checked details of Polygon ID new version release and features provided.

What’s next?
------------

The aim for next week (20th to 24th Feb) is to:

*   Start working on mobile app and try to integrate Polygon ID Wallet SDK in Flutter
    
*   Figure out the problem of onboarding via Web3Social Auth SDK but gasless transactions are not possible with Biconomy in Flutter
    
*   Go through docs for Polygon ID issuer server
    
*   Launch Github contribution contracts to polygon mainnet (as alpha version
    

More UI to see next week ✨

Never Stop Building ⚒️
