DAO Coders Inc has a requirement for a zero knowledge proof that will identify unique individuals to prevent Sybil attacks (one person having two or more pseudonymous accounts to gain disproportional influence).
The final solution would be a decentralized SSI service which would verify that an individual is unique within the service (using the developed zero knowledge proof), periodically proven to still be alive and issue a digital certification attesting to such to the user.
The user (holder) could then use that certificate as proof to third party verifier organizations (DAOs or otherwise) that the holder wishes to join.
The impact for DAOs, or other organizations, is that they would have a simple method for defending against Sybil attacks and proof of life. Members (holders) would have a single proof of humanity and life certificate that could be used to join many groups while controlling the information that is shared.
This solution tackles the Security and Zero Knowledge Proofs aspects identified in the challenge. A proof of humanity and life Self Sovereign Identity solution is also applicable to the broader Cardano community and would make Cardano a leading ecosystem by providing a uniquely improved service.
Marketing the service to the Cardano community will be done via Town Halls, social media and potentially a broader Marketing Campaign (see the DAO-NET & A2T Marketing proposal for details).
The main risk involves finding a qualified cryptographer willing to perform open source work at a rate that is likely to be funded under Project Catalyst, given their high demand and limited availability. To mitigate this risk, DAO Coders will reach out to IOG and the Cardano Foundation for possible recruiting assistance.
DAO Coders has several strategies to address the potential cost risks:
- By having multiple modular projects in each funding round there is a required overlap of funding to make each project functional on a stand-alone basis however as more projects are funded then the overlap can be used to cover potential shortfalls
- DAO Coders intends to launch a Mission Driven Stake Pool in May to help fund its operations
- Longer term solutions include a merchandising campaign (see the Merchandise Store project) and the DAO-NET: Development Funder project as additional revenue streams.
