This foundational milestone is dedicated to comprehensively understanding and aligning with the DDI Hub project’s requirements through detailed stakeholder engagement including coordination with the Reputation System team (to the degree time-synchronized) while outlining recruitment needs for additional personnel. We will conduct in-depth analysis to clarify expectations for the hub’s architecture integration protocols privacy/security and scalability moving from coarse-grained to fine-grained details covering must-have should-have and could-have requirements as per the RFP and our proposal. Initial exploration will target existing DDI solutions (e.g. Gitcoin Passport WaLT) and ecosystem components (e.g. voting portal) for integration scope. This phase establishes a mapping of functional interrelationships and non-functional needs (e.g. scalability data quality) setting the stage for subsequent milestones. This phase will adjust and refine subsequent milestones as needed and revealed by the project discovery/alignment. The budget will support hiring commencement and the next phase’s start.

Project Requirements and Alignment Document: Includes: - Stakeholder inputs encapsulated; - Insights from Reputation System team discussions (to the degree that it is possible and that the two projects are time-synchronized at this stage); - Must-have requirements (e.g. WaLT expansion ZKP KYC) and expectations; - Should-have requirements (e.g. modular architecture) and expectations; - Selected could-have requirements (e.g. advanced features) and expectations (to extent possible); - Non-functional requirements (e.g. scalability reliability) and expectations; - Non-conflict demonstration among planned requirements; - Initial scope of DDI solutions (e.g. Gitcoin Passport WaLT) and ecosystem components (e.g. voting portal blockchain explorer) with expected functionalities; - Recruitment plan for needed skills (e.g. DDI experts compliance specialists); - Details a refined/adjusted/updated project roadmap and milestones as needed.

- Stakeholder Approval: Document gains approval, verifying all must-have, should-have, and non-functional requirements are captured, and could-haves to the extent possible. - Clarity for Next Steps: Project plan provides sufficient definition to proceed to technical design, with clear scope and interrelationships. - Recruitment Planned: Hiring plan identifies any critical skills (e.g., DDI, ZKP, compliance) and a feasible recruitment schedule, aligned with project needs. - Milestones/Roadmap clarified.

This milestone initiates research to expand WaLT’s role as the DDI Hub’s foundation and analyze existing DDI solutions building on Milestone 1’s alignment. We’ll investigate WaLT’s potential to aggregate wallet addresses into a single user ID researching how it can link attributes from solutions like Gitcoin Passport and Privado using data collection (e.g. technical specs operational data) to assess feasibility. Research will identify requirements and unique aspects of these DDIs exploring compatibility and integration needs through literature reviews and comparative analysis. We’ll also explore how microservices outputs from the reputation system could map to a single unique identifier (UID) analyzing theoretical data flows without prototyping. This phase establishes a robust research base with cited sources informing WaLT’s expansion and laying groundwork for integration protocols ensuring alignment with must-have requirements and leveraging hired expertise.

- WaLT Expansion Analysis: Research report on WaLT’s potential to unify addresses and link DDI attributes with feasibility findings; - DDI Research Report: Detailed analysis of existing solutions (e.g. Gitcoin Passport WaLT) their features and integration gaps with citations; - UID Mapping Study: Theoretical exploration of mapping reputation microservices outputs to a UID with conceptual outcomes.

- WaLT Researched: Analysis confirms WaLT’s address aggregation potential and attribute linkage feasibility; - DDI Comprehensive: Report details multiple DDI solutions, identifying specs and gaps, supported by references; - UID Mapping Explored: Study outlines viable mapping approach for microservices to UID, conceptually sound per analysis.

This milestone defines integration and data sharing protocols and establishes initial privacy measures. We’ll specify what data and identity-related information ecosystem components (e.g. voting portals) share setting clear guidelines for external services with APIs and endpoints data formats and protocols and access control and permissions. Research will benchmark technical standards for interoperability. Simultaneously we’ll evaluate optimal Zero-Knowledge Proof (ZKP) KYC solutions (SaaS vs. on-premise) propose methods for self-sovereign control and implement mechanisms to anonymize or pseudonymize data. The data lifecycle within the DDI Hub (storage processing deletion) will be outlined to meet privacy and security standards with procedures for initiating processing and terminating identity verification requests. This builds on prior research using cited analysis to ensure must-have functionality.

- Integration Protocols Document: Specs for APIs data formats and access controls for hub integration; - ZKP KYC Evaluation: Comparative analysis and recommendations for ZKP solutions; - Privacy Specs: Methods for anonymization self-sovereign control and data lifecycle with verification processes.

- Protocols Defined: Document specifies APIs, data formats, and access controls, validated technically; - ZKP Recommended: Evaluation compares solutions, with level of security compliance reported; - Privacy Established: Specs anonymize data and cover lifecycle stages.

This milestone strengthens the DDI Hub with a security and compliance framework. We will embed privacy and security by design and by default addressing key vulnerabilities such as spoofing and fraud through the development of best practice guidelines and risk mitigation strategies. Our efforts include researching and proposing robust procedures for revoking identities during security breaches ensuring that compromised credentials are promptly invalidated. Compliance with GDPR CCPA and other frameworks will be researched recommending approaches for privacy and data security and identifying potential risks in identity management building on prior risk assessments. We’ll also propose methods for private data storage with user control enhancing should-have privacy goals. This phase integrates technical and legal research using findings to ensure the hub meets must-have security and compliance standards.

- Security Guidelines: Best practices to mitigate vulnerabilities with risk assessment; - Compliance Report: GDPR/CCPA recommendations with risk analysis and sources; - Storage Proposal: Methods for user-controlled private storage with feasibility outline; - Revocation Process: Procedures for timely identity revocation recommendations.

- Security Robust: Recommended guidelines for addressing vulnerabilities; - Compliance-aligned: Report recommends approaches for GDPR/CCPA compliance, mitigating risks in identity management; - Storage Viable: Proposal identified methods enabling user controlled private data storage; - Revocation Procedures: Recommended procedures for revoking identities in case of breach.

This final milestone ensures scalability and delivers a comprehensive design for a DDI Hub solution. We’ll identify methods to tie identities to unique verifiable individuals preventing duplication and test scalability under load. The hub’s modular architecture design will be finalized maximizing scalability modularity composability and extensibility for future DDIs with standards identified. Optional advanced features (e.g. soulbound tokens proof-of-humanhood proof-of-AI) and a privacy-preserving integration with WaLT/SNET will be researched if not already done in prior milestones. All prior work will be synthesized into a final report meeting non-functional needs (e.g. data quality reliability) with cited findings technical recommendations and three RFPs for next steps. This milestone delivers a robust future-ready hub design aligned with all RFP goals.
