Project Description

AvailDA Integration: Utilizes AvailDA's blobspace to store encrypted identity data, ensuring high availability and data integrity. Leverages AvailDA's expandable nature to accommodate growing identity datasets efficiently.

Polygon CDK: Build a custom rollup using Polygon CDK, optimized for identity management operations. Implements smart contracts for identity creation, verification, and management.

RISC Zero zkVM: Use RISC Zero zkVM to generate zero-knowledge proofs for identity verification without revealing sensitive information. Implements privacy-preserving computations for identity attributes and claims.

Light Client Verification: A light client for end-users to verify their identity data posted by the sequencer on AvailDA. Ensures quick and efficient verification of identity claims without downloading the entire dataset.

How it's Made

Privacy: Zero-knowledge proofs ensure users can prove their identity without revealing unnecessary information. Scalability: AvailDA's expandable blob space allows the system to grow with increasing users and data. Security: A combination of AvailDA, zkVM, and light client verification provides multiple layers of security. Interoperability: Support for decentralized identity standards ensures compatibility with other systems. Cost-efficiency: Utilizes AvailDA's cheap data availability layer for storing large amounts of identity data.
