Please describe your proposed solution.

As a step of development of our Cardano Invoicing System that utilizes DiD (Distributed ID) infrastructure, to permanently store timestamped invoices informaition on IPFS (Content Addressable Storage), we will need users to hold and be able to present their DiD as NFT in their crypto wallets.

How does your proposed solution address the challenge and what benefits will this bring to the Cardano ecosystem?

The integration of Self-Sovereign Identity (SSI) into crypto wallets can offer several advantages:

• SSI wallets provide users with greater control over their personal data.
• The users can conveniently manage their cryptocurrency holdings and digital identities within a single application, eliminating the need for separate wallets and authentication processes.
• SSI wallets enable individuals to prove their identity without sharing unnecessary personal data. This can be beneficial when conducting transactions on blockchain networks.
• Integrating SSI wallets into crypto wallets can assist in meeting regulatory requirements related to Know Your Customer (KYC) and Anti-Money Laundering (AML) protocols.
• SSI wallets empower people by giving them control over their personal data. Users can decide what information to share, with whom, and for what purposes, allowing for a more user-centric approach to digital interactions.

How do you intend to measure the success of your project?

1. Integration of DID / SSI as NFT will give options for Business Owners to use Cardano Blockchain, which will boost the overall popularity and TVL on the Cardano Blockchain
2. We going to provide Cardano users to use DiD connected NFTs to various transaction and will allow this transaction to be subject of KYC and AML requirements.
3. Also we going to provide application for storing and sharing Invoice information on the Cardano Blockchain

Please describe your plans to share the outputs and results of your project?

Our solutions will be open source and could be used openly, but we will also provide this as service to interesting customers, as part of bigger solution for business tools to use Cardano Blockchain.

What is your capability to deliver your project with high levels of trust and accountability?

We have a great, motivated team with more than 40 years combined IT and more than 10 years combined crypto & Cardano experience.

What are the main goals for the project and how will you validate if your approach is feasible?

Integration of SSI / DID as NFT will give to crypto wallets owners the opportunity to comply with KYC / AML regulation in given countries.

This could lead to better solutions on the Cardano Blockchain directed to Small businesses around the world and better visibility to Cardano Community as whole.

Please provide a detailed breakdown of your project’s milestones and each of the main tasks or activities to reach the milestone plus the expected timeline for the delivery.

T1.1: Integrate our solution with Sidetree DID solutions and store DID - will take 4-5 weeks

T2.1: Integration of DiD enable wallet with Crypto wallet to be able to operate with both resources

• Developing a library to integrate DID with regular Crdano crypto wallets - 6-7 weeks
• Smart Conctract to issue NFT DID and tooling around it - will take 2-3 weeks

T3.1: System-level designs and integration 3rd Parties could request access to encrypted Invoices - will take 4 -5 weeks

Please describe the deliverables, outputs and intended outcomes of each milestone.

• Repository with updated Cardano-Sidetree updated to latest Sidetree protpcol and working with Deno environment
• Application to store Business Invoices on Cardano Blockchain
• DiD Tools library to easily integrate DiDs NFTs with your crypto wallets
