The proposal directly addresses the challenge by creating integration between ATALA Prism and RootsID wallets, and making them interoperable with Hyperledger Aries and Indy. Hyperledger Indy is a popular SSI framework from The Linux Foundation, and is interoperable accross blockchains. Hyperledger Aries connects the SSI framework to Atala PRISM. The proposal is also impactful for bringing support to these for zero-knowledge proofs making them conform to the W3C Open Badge 3.0 standard. So the proposal extends capabilities and integrates projects.

The problem statement is short and to the point. The problem defined is in the scope of the challenge.

The positive impact on Cardano ecosystem is in promoting the development and adoption of SSI, which is often named as a crucial component of widespread adoption of blockchain.

The value added to the ecosystem is creating an interoperability solution between several SSI/DID framewrorks.

The KPI's of the proposal align with the challenge KPI's

Therefore I think the impact rating is 5

This proposal seeks funding for the development of Zero-Knowledge Proof and Predicate integration layer for ATALA Prism on RootsID CLI-WAL wallet and make them interoperable with Hyperledger Aries and W3C OBv3. The problem that this proposal wants to solve is clearly explained, ATALA Prism and RootsID don't support Zero-Knowledge Proofs and Predicates. This project will be build on the work of previously funded proposal “Hyperledger-Prism Interoperability” in F7. The project will be developed in collaboration with Rodolfo Miranda, Lance Byrd, Esteban García, Butch Clark, and the RootsID research team. The proposal clearly addresses the challenge by building an interoperability solution. I strongly agree that this proposal effectively addresses the challenge.

The problem described in this proposal is closely aligned with the challenge, directly addressing the challenge. Decentralization is a central and very important pillar for any public blockchain, focusing on building interoperability between decentralized identity solutions built by businesses with blockchains. Cross-chain projects from more than 20 companies as listed in this proposal will greatly help the Cardano Ecosystem. At the same time, it is also aiming for full cross-chain interoperability when the W3C Obv3 Ecosystem is formed. The proposal also clearly states the risks and measures to deal with those risks during project implementation, reducing risks for the project and bringing a higher probability of success.

I am not associated with these projects directly, but a project I am involved in would greatly benefit from this bridge. Hyperledger is used at many U.S. Universities in order to place education credentials onto the chain. Applications involving DIDs and SSI right now run into Hyperledger solutions before Cardano ones, so this bridge would target that weakness. Some projects just end up on Hyperledger due to the fact that they are the ones being accessed at these universities.

This proposal addresses the challenge of cross chain collaborations by building a zero-knowledge proofs (zKP) for decentralized identities (DIDs) on ATALA Prism. By having these tools, people from other chains and people not familiar with blockchain technologies will grow the Cardano ecosystem greatly. The team have already made many connections with teams from different blockchains and communities to build this zKP on ATALA Prism. They also are part of W3C Credentials Community Group Open Badge which is a cross chain solving for DIDs. The team have stated the risks for this project and majority of them have already been solved by having partnerships with ATALA Prism, IOG, Emurgo, Hyperledger, Plutus devs, etc. This project will be able to scale globally because they are solving DIDs with zKP which will bring more people to the blockchain space. The success of this project is high as many partnerships have been built.

Based on the proposed solution, Snapbrillia in collaboration together with RootsID team would like to bring on interoperability feature between Atala PRISM with Hyperledger Aries. This is in my opinion a well though proposal that will help more project use Atala PRISM for DID use case or simply bridge the Hyperledger with Cardano blockchain. The proposal itself answers the cross-chain collaboration challenge by implementing technical connection between Cardano to Hyperledger Aries (building bridges). Furthermore, the key metric is also aligned with the challenge key metrics. That is adding number of technical implementations connecting Cardano to other blockchains. After all, this project will be build by the Atala PRISM Pioneers and will be made available (open-source) for the whole Cardano community, giving greater impact for the next Atala PRISM developers/pioneers that want to build project in this field.

The project is very auditable. For one, the project will be open-source on Github (with both RootsID an Snapbillia repos) where everyone can measure its progress with the projected milestones. Snapbrillia also hosts monthly townhall meetings to provide updates to milestones. Also, there are several kpi's including thew number of DIDs, verified credentials, zero-knowledge proofs, and dApps and projects on mainnet built on ATALA Prism, and Hyperledger.

The information about auditing is abundant: there is roadmap with milestones, discord server.

The KPI's make sense and can be used to track the implementation of the proposal.

The proposal names several ways the community can track the progress of the implementation.

The information provided is sufficient to assess the progress and success of the first 3-month phase of the proposal. In addition, the milestones provided are sufficient to assess the success of the project at 6 and 12 months. The KPIs have been carefully selected and I believe they are good indicators of success. Proposed Outputs are reported at least once to twice per month for community engagement and feedback on progress until the end, the proposal joins most Catalyst Town Hall and work closely with ATALA Prism, RootsID, Hyperledger Aries and other partner to provide updates to the community. I think this proposal should be funded to help fulfill Snapbrillia's mission, to help launch the Cardano dApps community into the Metamask world and strap Snapbrillia along for the wild ride to the moon and back.

Many links to many materials as I mentioned on the 2nd prompt. They are active on Discord, and are answering questions. Twitter is active. Nothing stands out to me as info lacking. I found going through their materials inspiring, and more than just placeholder content. It is material worth browsing in and of itself.

Audibility on this proposal is quite easy. The team have prepared multiple ways to audit their progress of this project and they will publish publicly. They will also open-source codes for ATALA Prism ZKP and Hyperledger Aries in Github for anyone to audit. The team will be in Catalyst Town Halls regularly to update the community on their progress as well. They also have a discord channel for the community to get updates from the team. The team show a deep understanding of potential challenges by having building zKP for DIDs in the ecosystem. All in all, I strongly agree that this proposal provides me with sufficient information to assess the progress in attaining its stated goals.

It is often said that a successful project needs a good planning beforehand. I see that the Snapbrillia team give a good roadmap/product timeline to achieve want they want to deliver from this project. Equally important, the KPI/metrics is clear & measureable. And for the sake of transparence, they will host demo in the After Town Hall at least once to twice a month. Community could also check the development progress via their GitHub link https://github.com/snapbrillia/. Additionally, the team wrote clearly what they want to achieve starting from providing Atala PRISM & RootsID with z-KP functionalities until expanding Atala PRISM interoperability with Hyperledger. I give 5 stars for the auditability based on all information above.
