Please describe your proposed solution

The Cardano/KERI identity ecosystem is the leading blockchain implementation of the KERI identity protocols. KERI supports production identity solutions such as the GLEIF vLEI providing secure organizational identity in banking, finance, supply-chain, telecom and cross-border industries.

Aligned with Cardano Foundation, RootsID is promoting Cardano as the main Blockchain Watcher for GLEIF vLEI Identifiers and Verifiable Credentials. We are strongly believers that Cardano is the best alternative to provide transparency, auditability, availability, timing, consensus, and decentralization to Enterprises and Legal Entities. To push the adoption, we propose to enhance the open source Signify Browser Extension to support extra capabilities and publish a production version in the main browser stores.

In order to understand the importance of the solution we need to explain what the GLEIF vLEI ecosystem is.

The vLEI is an ISO standard, standing for “Verifiable Legal Entity Identifier,” is a digital and cryptographic evolution of the traditional entity identifier known as LEI. It enables decentralized and automated validation of organizational identities. vLEI also allows the distribution of credentials that link individuals to formal organizational roles, allowing them to authenticate their identity in various activities from financial transactions to official communications.

The Legal Entity Identifier (LEI) was established in the wake of the 2008 financial crisis, providing a distinct and unique identifier for entities involved in financial transactions. While the LEI system has significantly enhanced transparency in the financial sector, the rapid pace of digital transformation called for its evolution. To meet the needs of the modern digital ecosystem, the Verifiable LEI (vLEI) was introduced. The vLEI retains the unique identification attributes of the LEI and augments them with verifiability, ensuring that the digital identity is both authentic and unaltered.

We should also introduce the KERI technology. You can find useful to hear the following interview at the Cardano Summit 2023 to Thomas Mayfield, team lead of Cardano Foundation's Decentralized Trust and Identity Solutions, or to read the following post at Medium that we use to cite the following:

In recent years, the Key Event Receipt Infrastructure (KERI) has emerged as one of the most promising technologies within the Self-Sovereign Identity (SSI) ecosystem. It was first presented by Sam Smith in his paper . KERI has a decentralized secure root-of-trust based on cryptographic self-certifying identifiers. It uses hash chained data structures called Key Event Logs that enable ambient cryptographic verifiability. In other words, any log may be verified anywhere at any time by anybody. It has separable control over shared data which means each person or entity truly controls their own identifiers.

<u>Our Solution</u>

We will enhance the KERI secure browser extension and publish a production version in the browser stores to enable webapp builders and users to participate in the Cardano/KERI vLEI ecosystem. This browser extension was initially developed by RootsID as the winners of a [bounty](<https://docs.google.com/document/d/1mq82RDRGfoOMCs8sR8Cuj_hMC5i1_aP7e6DVqp8o13g/edit#heading=h.br04cm4k5rsy >) provided by Provenant.

The browser extension, initially implemented for Chromium browsers, uses signify-ts to connect to a KERIA agent and retrieve user Indetifiers (AIDs) and their associated keys and credentials. Those AIDs and credentials are used to sign in to enabled websites. Once a signin is associated with a website, it's stored in chrome store for future use.

The Signify Browser Extension as in its current state lacks some basic features needed to support Cardano as well as advance functionalities to issue and present verifiable credentials.

In this project we propose to implement the following features to the open source project:

• Support for AID Key Event Logs backed in Cardano
• Support for single-signature indentifier operations
• Support for multi-signature identifier operation
• Out of Band Introductions
• Cryptographic challenging and responses
• Credential presentation exchanges (IPEX protocol)
• Integration wallet-webapp

Finally, we will publish the production version of the identity browser extension to the main browser stores.

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

GLEIF vLEI ecosystem is being adopted globally and as the number of participating companies grows, it will increase the use of verifiable credentials that enables a smarter, less costly and more reliable way to make decisions about who to do business with.

We believe that if we can position Cardano as a first option for a witness of their Legal Identifiers, the adoption and usage of vLEIs will directly impact in the adoption and promotion of Cardano. That is the business value that we are envision to generate to Cardano with this project.

We are also leveraging the following Cardano projects:

• Cardano Foundation Identity Wallet: <https://github.com/cardano-foundation/cf-identity-wallet/blob/main/README.md>
• RootsID Cardano Watcher: <https://projectcatalyst.io/funds/11/cardano-open-developers/gleif-network-super-watcher-on-cardano-by-rootsid-725aa>
• RootsID Cardano Backer (PoC): <https://cardano.ideascale.com/c/idea/64263>
• DoulaID: <https://projectcatalyst.io/funds/12/f12-cardano-use-cases-concept/maternal-mortality-crisis-solution-doulaid-an-identity-app>

This project is not only of importance to Cardano, but also to the GLEIF vLEI ecosystem and the KERI community. As regular participant of those communities, we will share the results with them and promote the usage to participating companies.

The real metric of success is the adoption of Cardano as a Root of Trust to Organization Identity. That metric can be tracked by the Cardano Watcher in the blockchain.

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?

RootsID is supremely confident in our ability to implement this solution. And the KERI/Cardano ecosystem is by far the most advanced KERI and vLEI blockchain implementation:

• RootsID is the primary implementor for the KERI secure browser extension. We know it inside and out.
• RootsID is also the original implementor for the KERI Super-Watcher and Cardano KERI Backer which were funded by Catalyst. We know them inside and out.
• RootsID is integrating with the Cardano Foundation mobile identity app in our F12 Catalyst proposal DoulaID and are in regular contact with their development team. We are highly confident in our ability to integrate with their excellent identity wallet.
• RootsID has helped the GLEIF vLEI ecosoystem on several projects including a Pilot with a European Regulator, which implements a webapp using the KERI secure browser extension.
• RootsID has already put into place a test harness for vLEI webapp solutions. It is ready for Cardano/KERI test cases.

We've been delivering Open Source building blocks for the Self-Sovereign Identity ecosystem in Cardano since Fund 6. Our funded proposal are listed in lidonation where you can find that we have delivered successfully and on time more than 15 funded proposals.

Additionally, the team participates actively in the worldwide SSI community by attending and collaborating to several working groups in the Decentralized Identity Foundation, the Hyperledger foundation, the Trust over IP foundation, and the KERI community.

We’ve been providing technical services and consultancy on Decentralized Identity to several companies and organizations including:

• IOG
• Cardano Foundation
• GLEIF
• Provenant

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

Since we are participating in multiple proposals we have carefully planned our time allocation for each of us. We defined our individual commitment per week as if all of the proposals are funded including extra activities. Based on that, we defined the allocation per proposal for each of us needed to deliver the proposal in time.

Please provide a cost breakdown of the proposed work and resources

Budget is mostly composed of development hours at a ratio of ₳200/hr, plus the hosting costs. Based on the activities defined above the requested breakdown budget is:

• Design: 20hr = ₳4.000
• Documentation: 20hr = ₳4.000
• Project Plan: 20hr = ₳4.000
• Development: 300hr = ₳60.000
• DevOps tasks: 50hs = ₳10.000
• Test and improvement iterations: 50hr = ₳10.000
• Yearly AWS instance: ₳1.200
• Domain name + SSL: ₳100

TOTAL BUDGET: ₳93,300

No dependencies

How does the cost of the project represent value for money for the Cardano ecosystem?

The cost of the project goes directly for the development of an open source product that can be by dappes and webapps to create business around business that holds vLEI credentials. Likewise, we envision that the product will help onboard Legal Entities/Organizations that participate in the vLEI GLEIF ecosystem. The real value is provided when those Organizations anchors their Organizational Identities in Cardano, producing actual transactions in the blockchain that contribute in the trustfulness of their business operations. By this means, not only the transactions fees contribute to the Cardano ecosystem, but also consolidates the benefits of Cardano Business community.
