Designing Trust: Making Zero-Knowledge Proofs Accessible to Non-Technical Users.
My challenge was to make invisible cryptography trusted by non-technical users. I translated complex Zk-Snark logic into a clear, linear voting interface that allows Juries to resolve high-stakes disputes without needing to understand the math.
Complexity Breeds Distrust
Users needed to stake real money on disputes, but the underlying tech (Zk-Snarks) was mathematically complex and invisible. The core friction was trust: "How do I know my vote is counted if I can't see it?" If the interface felt opaque, users wouldn't stake funds, and the system would fail.
From Complexity to Clarity
Usability: Successfully simplified a complex cryptographic process into a linear 4-step flow. Delivery: Delivered high-fidelity prototypes that enabled the team to implement Polkadot.js integration ahead of schedule. Validation: Enabled the successful demo of privacy-preserving voting on the AlephZero testnet.
Visualizing the "Black Box"
The challenge was displaying votes that the user cannot see yet. I used a "Locked" card state to represent encrypted votes. This visual metaphor builds trust that privacy is active without requiring the user to understand the cryptography behind it.
Humanizing the CLI Integration.
The "Verify" button isn't just a toggle—it triggers a heavy off-chain calculation via CLI. I designed clear Feedback Loops ("Loading" -> "Verified") to bridge the gap between the browser interface and the command-line proof generation, managing user expectations during latency.
Mapping UI to Smart Contracts.
I designed the input fields to map 1:1 with the Ink! Smart Contract constructor. The interface validates wallet address formats and strictly separates "Staking" fees, ensuring that when a user hits "Create," the payload matches the chain's validation logic perfectly, preventing failed transactions.
