Reclaim Protocol - Bringing Web2 Identity to Web3

Reclaim Protocol makes https traffic verifiable using Zero-Knowledge Proofs, enabling users to generate verifiable credentials from any of their online user profiles. This unlocks unlimited possibilities as no APIs are required or no changes to be made to the websites to extract user private data, while guaranteeing data integrity. Web2 user data which was elusive to Web3 till now will be available across dapps on Cardano. Dapp developers can leverage Reclaim protocol to build multiple use cases related to Identity, sybil resistance, proof of personhood, etc on top of Cardano.

Technical Overview

Reclaim empowers users to generate Zero-Knowledge Proofs for any online user profile. To generate a claim, users first need to log into the relevant website. This login process, involving an HTTPS request and its subsequent response, is channeled through an HTTPS Proxy Server known as an 'attestor'. This attestor oversees the encrypted data exchange between the user and the website. Subsequently, users provide keys that disclose non-sensitive parts of the request to the attestor. With this, the attestor can view the request in its entirety, barring confidential details like authentication data, and can confirm its legitimacy.

The website's encrypted response is then processed by a zk-circuit, which identifies a regex match within the encrypted data using a decryption key as a confidential input. The attestor further validates that the zk-circuit's public input was indeed the encrypted data sourced from the website. With these attestations on both the request and the encrypted response, coupled with the zk-proof, any third-party application, whether on-chain or off-chain, can verify the existence of data that exists on the user’s profile.

User credentials in Reclaim Protocol are generated and stored completely on the client side. Using Reclaim, users can generate Proofs(Groth16) in less than 10 secs even on a 2015 Android Device!

[IMPACT] Please define the positive impact your project will have on the wider Cardano community.

Reclaim enables composability of Web2 data on Cardano and breaks the barriers of data exchange between web3 and web2.

Enhanced Interoperability:

Applications can access user data without the need for APIs. By empowering Dapps in Cardano ecosystem to access user data from Web2 platforms, we can significantly expand the range of applications and use cases that can be developed on Cardano, especially those focussed around KYC, sybil resistance, proof of personhood, thus driving significant ecosystem growth.

User-Centric Data Access:Reclaim’s commitment to self-sovereignty and user consent in data access aligns with the decentralized and user-centric principles of the Cardano ecosystem. This ensures that Dapps built on Cardano utilizing Reclaim Protocol are adhering to robust data privacy and user consent norms.

Enabling New Use-Cases:By facilitating access to off-chain user data, Reclaim Protocol can enable the development of new, innovative use-cases on Cardano, such as Skill IDs, P2P onramp/offramp, Gossip marketplaces, or social Dapps that utilize user data from Web2 platforms.

Enhanced Developer Mindshare:By facilitating new and unique use cases that leverage off-chain data, Reclaim protocol will attract a broader developer community to Cardano enriching its ecosystem and increasing its competitive edge

[CAPABILITY & FEASIBILITY] What is your capability to deliver your project with high levels of trust and accountability? How do you intend to validate if your approach is feasible?

Reclaim is already in production and in the last two months of coming out of stealth, we have made the following progress:

1. Integrated Reclaim to Polygon ID, EAS(Ethereum Attestation Service) and working on integrations with Gitcoin Passport and Disco.
2. Deployed on major L1/L2s including Linea, Nibiru, Polygon, Optimism, BNB
3. Enabled Dapps such as P2Px.finance( generated $150K transactions in last 5 weeks), Coded Estate (RWA application on Nibiru) and a few other applications
4. We are currently working on close to 15 other integrations with both Web2 companies and Web3 applications
5. Working on identifying identity and citizenship solutions for the countries of India ( MOU with NIELET-the IT skilling department), Turkey and Uzbekistan

We built Questbook.app, an on-chain grants management tool and have been successfully running it for nearly 2 years managing grants for large L1/L2s including Polygon, Compound, Arbitrum, Ton etc. Questbook platform has disbursed more than $3 Mn to more than 250+ developers and engaged with more than 25000 developers.

Written more 100 tutorials for web2 developers to transition to web3 (http://openquest.xyz/). More than 20000

Built DAuth a decentralized OAuth alternative (https://github.com/madhavanmalolan/dauth)

Authored EIP 1361 (https://github.com/ethereum/EIPs/issues/1361)

Retroactive funding in education mechanism design research (https://ethresear.ch/t/retrofunding-dao-for-education/10821)
