Problem

Current DAO governance voting suffers from several issues:

• Public Voting: Addresses and choices are visible, leading to whale dominance and small participant coercion.
• Coercion & Bribery Risk: Votes can be influenced by external incentives because everything is verifiable and transparent.
• Low Participation: Members are discouraged from voting due to social or financial pressure.

SilentDAO addresses these challenges by providing anonymous, verifiable, and low-cost voting on Mantle.

Solution

SilentDAO adds a privacy layer on top of Mantle's L2:

1. Eligibility Proof (ZK Membership Proof): Verify voters are qualified without revealing identities.
2. Private Vote Commitment: Votes are hashed/committed on-chain to ensure privacy.
3. Anti-Replay (Nullifier): Each voter can only vote once, preventing double-voting.
4. Verifiable Tally: Votes are counted and results can be verified on-chain, preserving anonymity.

Demo

We prepared a 3–5 minute demo to showcase SilentDAO:

1. Step 0: Problem Intro

   • Compare public voting vs SilentDAO voting.

2. Step 1: Create Proposal

   • DAO admin creates a vote on the front-end.

3. Step 2: Submit Anonymous Vote

   • Voter submits vote using ZK Membership Proof.
   • Vote content remains private on-chain.

4. Step 3: Prevent Double Voting

   • System rejects duplicate votes using Nullifier logic.

5. Step 4: Tally Results

   • Display anonymous, verifiable results on-chain.

6. Step 5: Verify Results

   • Anyone can verify vote integrity without revealing identities.

The demo shows anonymous voting + verifiable results + low-cost execution on Mantle.
