Fast. Scalable.
Engaging.
Cryptographically verified digital voting for live events, media, and lower-stakes organisational ballots. Real-time dashboards, zero-knowledge proofs, and no central personal data store.
The same cryptographic engine — calibrated for speed and scale
Votercare Lite shares its core voting engine with Votercare Max: zero-knowledge proofs for eligibility, nullifier-based double-vote prevention, and Benaloh challenge vote verification. What differs is the identity assurance level at the front end — no in-person proofing, no maker-checker credential issuance.
This makes it fast to deploy and affordable at scale, while still offering meaningful cryptographic verification of the ballot itself. It is the right tool for contexts where the stakes don't require the full operational overhead of the maximum-assurance tier.
The live provisional count and the verified final result are deliberately separate outputs. During the voting window you see a fast, eventually-consistent counter. After the window closes, the verified tally runs — with nullifier deduplication and ZK proof verification — and produces the number with cryptographic guarantees behind it.
Features
Everything you need for high-quality digital voting, without unnecessary complexity.
Live provisional dashboard
Real-time vote counts visible during the voting window — the same architecture used for live sports scores. Fast, cacheable, and always current.
Zero-knowledge eligibility
Voters prove they're eligible without revealing who they are. A Merkle-tree commitment and nullifier prevent double-voting without identity storage.
Benaloh challenge
Voters can audit their own ballot at any time — the device reveals its encryption randomness for verification — without creating a coercion-enabling receipt.
Verified final tally
After the voting window closes, nullifier deduplication and ZK proof verification run to produce a cryptographically audited final result.
Lightweight eligibility
No in-person identity proofing required. Eligibility can be based on an app account, phone number, or device-based deduplication — appropriate for entertainment-tier stakes.
Open source
All code is publicly available and reproducibly built. Security and fairness properties are independently verifiable, not just claimed.
Who is it for?
Any organisation that wants credible, verifiable digital voting without a full identity-proofing infrastructure.
Live debate voting
Audience polling during televised debates or live-streamed events, with real-time dashboard visible on screen.
Professional bodies
Member votes for lower-stakes governance decisions — advisory polls, preference rankings, committee elections.
Media & entertainment
Audience choice awards, viewer polls, fan votes — with meaningful cryptographic verification behind the numbers.
Educational institutions
Student union elections and campus polls with genuine verifiability at affordable cost.
Under the hood
Lite vs Max
Same cryptographic engine, different identity assurance level at the front door.
