DAO
Describe what makes your idea innovative compared to what has been previously launched in the market (whether by you or others).
Our project delivers the first fully anonymous DAO voting dApp built on both Cardano and Midnight (Cardano’s ZK Layer), enabling zero identity traceability via ZK-based commit–reveal voting. While existing DAO platforms on EVM and Cardano native chains reveal wallet addresses and voting actions, our solution ensures complete unlinkability. It combines a privacy-by-default UX with seamless integration to Cardano wallets, setting a new usability and privacy benchmark for DAO governance within the Cardano ecosystem.
Describe what your prototype or MVP will demonstrate, and where it can be accessed.
The MVP will showcase a complete DAO voting workflow connected to Cardano testnet via Midnight:
Describe realistic measures of success, ideally with on-chain metrics.
Please describe your proposed solution and how it addresses the problem
Problem Statement
In most DAOs today, voting is public, making it vulnerable to community pressure, intimidation, and “trend voting” behavior.
Moreover, no existing voting tool truly incorporates zero-knowledge (ZK) privacy at the end-user level.
Current Challenges:
Identified Needs:
Proposed Solution
We propose building a dedicated, privacy-preserving voting dApp specifically designed for DAOs, leveraging the native zero-knowledge (ZK) capabilities of the Midnight network.
The system provides complete voter anonymity while maintaining transparency, auditability, and trust in DAO decision-making.
This solution modernizes DAO governance by ensuring that no voter identity or individual voting behavior is ever exposed, while still allowing the community to verify that all votes are valid.
1. Core Objectives

2. System Architecture Overview
The solution is structured around three major components:
ZK Privacy Voting Engine (Core Logic Layer)
This engine governs the entire secure voting workflow using ZK cryptography.
Key functionalities:
No exposure of:
This mechanism guarantees:

3. Decentralized Voting Smart Contracts (On-chain Layer)
Smart contracts store only the minimal data required for correctness:
The contract accepts:
By relying on Midnight’s privacy layer:
4. Privacy-First Frontend dApp (UI/UX Layer)
A fully modern, responsive web interface that hides the underlying cryptography from end-users.
Key features:

Supported User Roles
The system includes workflows tailored to each governance participant:
Key Advantages

Please define the positive impact your project will have on the wider Cardano community
1. Strengthening Cardano’s Position in DAO Infrastructure
This project introduces the first fully anonymous, zero-knowledge DAO voting dApp built natively for Cardano’s ecosystem via Midnight. It addresses one of the most critical governance gaps — the lack of privacy in voting — which has been a limiting factor for enterprise and sensitive community use cases.
2. Unlocking Enterprise & Sensitive Governance Use Cases
With full privacy and no traceable wallet addresses, DAOs on Cardano can now confidently handle votes on corporate strategy, treasury allocations, compliance decisions, and politically sensitive topics without risk of voter intimidation or trend manipulation.
3. Setting a Usability Standard for ZK on both Cardano & Midnight
By pairing ZK proofs with a clean, intuitive UI/UX, the project lowers the barrier for non-technical DAO participants. This serves as a reference implementation for developers building privacy-first tools on Cardano and Midnight.
4. Strengthening Cardano’s Competitive Edge
In an industry dominated by EVM-based governance tools, this project showcases Cardano’s ability to deliver privacy-preserving, production-ready DAO applications — positioning the ecosystem as a leader in decentralized governance innovation.
5. Game-Changer for Cardano Governance
This project is not just a voting tool — it is a proof of what’s possible when Cardano’s core strengths (security, scalability, and community governance) are combined with Midnight’s zero-knowledge privacy layer. By delivering a working, open-source, anonymous DAO voting dApp, we show the world that Cardano can lead in privacy-first, enterprise-ready governance — an area where no other blockchain currently offers a complete solution. This positions Cardano not only as a platform for open participation, but also as the go-to choice for secure, censorship-resistant, and future-proof decentralized decision-making.
What is your capability to deliver your project with high levels of trust and accountability? How do you intend to validate if your approach is feasible?
Our Capability to Deliver
Our team combines expertise in blockchain development, zero-knowledge cryptography, UI/UX design, and DAO governance consulting. Key members include:
• Blockchain Developer – Experienced with Cardano native smart contracts and integration of ZK proof systems.
• Solution Architect – Designed scalable architectures for privacy-focused dApps.
• UI/UX Designer – Delivered intuitive, accessible interfaces for Web3 platforms.
• DAO Consultant – Provides governance structure insights and real-world DAO deployment experience.
• Project Manager – Oversees milestones, coordinates stakeholders, and ensures timely delivery.
We are working and building:
• System architecture design for ZK-enabled DAO voting on Cardano + Midnight.
• Wireframes and user flows for all voting phases (proposal, commit, reveal, tally).
• Technical validation of integrating Midnight ZK proofs with Cardano wallet authentication (CIP-30).

Feasibility & Validation Approach
• Prototype on Testnet – Deploy core voting features with ZK proof generation and verification on Cardano Testnet.
• User Testing – Involve both DAO operators and regular community members to validate UI/UX accessibility.
• Security Review – Conduct internal code audit focusing on privacy preservation and smart contract correctness.
• Public Documentation – Publish GitBook with technical details and governance use cases for transparency.
Our track record of delivering blockchain-based tools, combined with a detailed milestone plan and testnet-first deployment, ensures a high level of trust, accountability, and technical feasibility for this project.
