(DDI) Hub & Privacy-Preserving Smart Contracts

Expert Rating

n/a

Overview

This proposal aims to develop a Decentralized Digital Identity (DDI) Hub that integrates existing identity verification solutions while prioritizing privacy, security, and interoperability within the SingularityNET ecosystem. The project will explore smart contract-based identity verification, multi-network integration, and privacy-preserving mechanisms using Zero-Knowledge Proofs (ZKPs) and Self-Sovereign Identity (SSI) frameworks. The goal is to enhance decentralized identity management and develop a scalable, privacy-centric identity solution aligned with SingularityNET’s needs.

The goal of this project is to conduct research on solutions and requirements for a decentralized digital identity (DDI) hub tailored to the needs of the SingularityNET ecosystem and its reputation system. This will include research into how existing DDI solutions can be integrated into a single hub that will allow for the creation of reputation scores that can be tied to unique verifiable identities while maintaining privacy. Part of the RFP is the definition of 2 or 3 RFPs for development of the envisioned system. This RFP is closely connected to the Reputation Platform RFP, and should be guiding the data privacy and identity integration solution of that RFP.

Clear identification of DDI solutions and their integration potential. Documented API & data-sharing framework.

Milestone 2 - Prototype Development & API Design

Description

Build an initial smart contract-based prototype for the DDI Hub with multi-network identity verification and ZKP authentication mechanisms.

Deliverables

Prototype of the wallet-based identity aggregation system. APIs and endpoints for integration with the SingularityNET Voting Portal & Reputation System. Security testing & privacy compliance documentation.

Budget

$50,000 USD

Success Criterion

A functional DDI prototype demonstrating privacy-preserving authentication. Successfully tested API communication with SingularityNET components.

Milestone 3 - Full System Implementation & RFP Drafting

Description

Complete system development, integrate with Reputation System, and draft final RFPs for expanding the architecture.

Deliverables
