[SOLUTION] Please describe your proposed solution

In the current landscape, voting on polls, even those associated with blockchain ecosystems, typically ends up with the recording of votes and private data in centralised databases. This compromises anonymity and privacy, as our opinions are cataloged and potentially monetised without our consent. The only recourse seems to be abstention.

However, there is a superior alternative, starting by leveraging Digital Identities and Anonymous Verifiable Credentials. This approach enables community participation without compromising privacy. With my background in privacy-preserving applications like Authenly.com (2020) and cross-chain authentication systems such as SignWithWallet.com (2022), coupled with extensive experience in Digital Identity prototypes since 2020, and ongoing projects involving Digital Identity on the Cardano blockchain, I am well aware of the challenges faced by end-users and the industry at large, as well as the appropriate solution to put in place.

This project will build on all those past experiences. It aims to deliver a Digital Identity wallet as a browser extension. Users can create their Digital Identity, authenticate securely, and receive Verifiable Credentials. A Trust Authority Agent will issue and verify credentials, while a Decentralised Voting App will enable admins to create privacy-preserving polls, and users to vote securely.

It’s disheartening that many decentralised projects still rely on centralised authentication and participation systems, allowing a full tracking of end-users Personal Identifiable Information, endangering their privacy. Based on a Trust Framework, our solution provides a privacy-preserving alternative, essential for projects that prioritise their users’ security and privacy.

This solution will be impactful as it is made of an open Self-Sovereign Identity system as well as a Decentralised Voting system. All components of this proposals will be inter-operable but also independent: (i) the Identity wallet (browser extension) is a separate component in itself ; (ii) The trust framework issuing VCs is another separate component ; (iii) the voting app is also separate. It builds on top of the others, but should there be additional identity wallets in the future, it could plug onto those too.

Finally, I plan to engage with Catalyst (Cardano) and Deep Funding (Singularity Net) to highlight the superiority of our voting system over their current setups, some of which compromise user privacy by aggregating personal data into private databases. So many “decentralised” projects in the Cardano ecosystem still make use of private polls solutions. They will be the main beneficiaries of this solution.

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

This project will establish the infrastructure and technology for a secure, privacy-preserving, and decentralised voting system. All components will be delivered open-source and packaged for easy distribution and use. As such this project can deliver transformative impacts to the broader Cardano community. Success will manifest in several ways, bringing substantial value:

• Elevated Ecosystem Utility: Our Digital-Identity-enabled voting system enhances Cardano’s utility, making it a pioneering blockchain for Self Sovereign Identity (SSI) and its multiple use-cases. The ability to provide users with total security and privacy when they cast their vote introduces a novel dimension, attracting developers, users, and businesses.

• Community Engagement: By enabling users to easily create their Decentralised Identity and have the ability to vote with confidence of their privacy being preserved, we encourage increased community engagement. Developers and users will actively contribute to and benefit from an evolving ecosystem. Ultimately, a transparent, trustable, and privacy-preserving voting App on Cardano will encourage participation and collaboration.

• Quantitative Metrics: We will measure success through quantitative metrics such as the number of unique DIDs created via the Browser Extension app, number of Verifiable Credentials delivered, number of polls created, and number of participants in votes. These metrics will be tracked on-chain (DID) and off-chain (Polls, VCs).

• Impact: we hope to demonstrate that Cardano can also be used as a leading blockchain for innovations around SSI. There is a lot at stake, as when the world at large discovers the benefits of self Sovereign Identity, the early viable solutions will be in a great position to replace unwanted systems built for tracking and profiling end-users.

• Sharing Outputs: Regular updates of the open-source development effort, engaging the community to use Digital Identities and voting capabilities on Cardano, blogs, and social media to keep the Cardano community informed. Open source Proof of Concepts, documentation and tutorials will be provided to ensure accessibility and wider adoption.

  [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?

I have already delivered one project relating to End-User Authentication with Wallet, and I am in the process of delivering one relating to Digital Identity on Cardano:

• Sign-in with Cardano: this was a F8 project which has been downloaded over 1,000 times (https://github.com/incubiq/sign_in_with_wallet) It allows end-users to Authenticate via their Cardano wallet (like you have “sign-in with Facebook”, you can now “sign-in with wallet”

• Identity solution for Autonomous AIs living on Cardano: this project in half way through now, and you can see the open source repo (https://github.com/incubiq/ai_identity) which is an identity layer built on top of a Atala Prism Agent Node, to simplify the creation and management of Digital Identities and Verifiable Credentials.

Building on both past experiences, I believe that I am well prepared to deliver this project, which is basically the combination of Authenticating with a Wallet and Managing Digital Identities (DIDs).

The approach is very much validated already by the foundational layers delivered with those two past projects. In short, here is the approach I will take:

• Instead of a “Login with a Crypto wallet”, I will now develop an open source SDK to “Login with a DID”

• To make it user friendly, I will build a browser extension to act as a Digital Identity Wallet, which the end-user will use for authentication purposes, and transaction signing.

• the Agent Node delivered in the “Autonomous AI identity solution” will be repurposed to deliver all digital identity related credentials.

• A small App or DApp will be built to collect and certify an end-user voting power (such as consolidated amount of ADA on all user’s wallets)

• The connector with other crypto wallets already developed in the “Sign-in with Cardano” project will be leveraged and improved, to allow the issuance of Verifiable Credentials by a App/DApp

• Verifiable Credentials about the user will be stored on Atala Prism, and will be verified by the same App/DApp

• A Voting App will be delivered (including smart contracts) to create simple polls and allow end-users to vote.

• Integration of the end-to-end solution will be delivered in TestNet

  [PROJECT MILESTONES] What are the key milestones you need to achieve in order to complete your project successfully?

Milestone 1: M1 - Finalise all specifications

We will use the first milestone to finalise the specifications and provide small proof of concepts where necessary (see below). In particular, those areas whose specifications and technology choices will be refined are:

• Atala Prism and its Agent Node: we will review how / where the node is hosted, and the final specs of the connecting APIs to the agent node (likely via an intermediary API layer)

• Digital Identity wallet and Browser extension: we will review all constraints associated with the delivery of a browser extension for a “light Cardano wallet” which will mostly act as a Digital Identity wallet

• App vs DApp: this part is the least clear so far, so it will require a bit more research into what sort of App (decentralised or not) we will provide. The requirement is that the Identity Wallet will receive Verifiable Credentials from an Authoritative entity. Our App (or DApp) is this entity having authority on issuance. As of now, no other project has yet delivered in production a decentralised App for managing Digital Identities, hence our need to refine carefully our technology choices and specifications. We are working closely with the Atala Prism team, as part of a tiny cohort or 3-4 teams, to deliver this capability.

• Voting power: in a first instance, Verified Credentials will be issued to represent an individual’s “voting power”. This can take the form of aggregating ADA balance of several wallets, or in the case of more complex use cases, aggregating the balance of various coins over various wallets. A clear specification is required to issue such credentials and ensure there is no double counting (e.g. a user sending its ADA to another wallet and claiming double voting power).

• Voting system Design and UI: In the first iteration of the project, we will likely let users vote solely on “Polls”. Other categories of questions could be added later. A basic smart contract requirement and a simple UI will be designed during this stage.

  [RESOURCES] Who is in the project team and what are their roles?

The project team consists of Eric Duneau, who will manage, design, develop, and test the entire project. Eric brings extensive experience in the software industry, with over 20 years of experience and prior experience as CEO/CTO of a $30 million software business. After successfully selling the business in 2019, Eric has redirected his focus towards AI and Digital Identity projects on Cardano.

Eric has a proven track record of delivering projects within the Cardano ecosystem, and has set a delivery deadline for this project of nine months. Note that this project is estimated at 168 days at most, which is 8 months full-time. Therefore, it is set on a path of “easy to achieve” deadlines over 12 months.

The development of the Plutus/Aiken smart contract will be sub-contracted to an expert, and the security review will be delivered by another expert in smart contract security.

Any side material delivery, such as video production, marketing, and documentation may be subcontracted to a team which Eric has been working with for several years.

[BUDGET & COSTS] Please provide a cost breakdown of the proposed work and resources

The cost of the entire project is calculated at ₳235,310, but was discounted by 25% to deliver high value for money. The original cost was calculated as follows:

• Cost per hour: dev at $85 ph ; test and risk mgt at $55 ph ; doc and marketing at $35 ph
• Total number of days = 168, for an average of $76 per hour across the project
• ADA/USD conversion rate: 0.435 (taken on 14th May 2024)

The table below explains the real (original) cost per each activity:

In summary, the final budget retained for each milestone is as per below:

• Milestone 1 (Finalise all specs) : ₳30,000 (17%)
• Milestone 2 (Digital Identity Wallet) : ₳24,000 (14%)
• Milestone 3 (Authority VC issuance App) : ₳50,000 (28%)
• Milestone 4 (Voting App) : ₳50,000 (28%)
• Milestone 5 (Connecting all SubSystems) : ₳20,000 (11%)
• Final Milestone (Close-out Report) : ₳2,500 (1%)

Total = ₳176,500 ($76,777 ; 168 days ; $57 per hour)

[VALUE FOR MONEY] How does the cost of the project represent value for money for the Cardano ecosystem?

The cost of the project represents excellent value for money. As the main developer, Eric is based in the UK, where he generally command a rate way in excess of the average $57 per hour agreed for this project (168 days, for 176,500 ADA).

This project addresses the integration of a decentralised voting App and SDK into Cardano, which will touch and benefit all industries. Here are two obvious examples:

(i) Catalyst as a voting system, which is still currently a private based application prone to leak data privacy, would benefit its users to use such a Decentralised Identity voting system ;

(ii) in the Cardano eco-system, SingularityNet have build a voting wallet called Walt, which is consolidating privately all public addresses of a user, and therefore exchanges the right to note against giving away all anonymity ; They would benefit greatly to plug on such a SDK.

The reach is wide, and the opportunity to place Cardano as a global leader in Decentralised Anonymous Voting built on a Trust Framework is not to be missed.

Finally, the project’s costs have been carefully considered and down-adjusted by a 25% discount to reflect a fair and proportionate investment. By delivering exceptional value for money, at 176,500 ADA, this project maximises the impact of the allocated resources and aligns with the goals and aspirations of the Cardano ecosystem.
