VoteChain is an end-to-end verifiable e-voting platform combining blockchain accountability, homomorphic encryption, and biometric authentication — all powered by open-source technology.
Trusted by leading institutions worldwide
Every layer of VoteChain is built from the ground up for trust, privacy, and verifiability.
Every vote is cryptographically signed, timestamped, and anchored to a permissioned blockchain. Voters receive a receipt to verify their ballot was counted.
Ballots are tallied without ever decrypting individual votes. Our threshold MPC ensures no single entity can reveal a voter's choice.
Face-based 1:1 verification with anti-spoofing liveness detection ensures only eligible voters participate — no passwords to steal.
Every system event — registration, login, vote casting, tallying — is written to an append-only ledger and blockchain-anchored.
100% open-source software: CompreFace, Keycloak, Hyperledger, MediaPipe, and more. Full code auditability and vendor independence.
Cloud-native microservices with horizontal pod autoscaling, event-driven communication, and distributed caching handle millions of concurrent voters.
From registration to results — every step is secured by cryptography.
Voters register with government-issued ID and enroll a biometric template via CompreFace 1:1 matching. A device-bound ECDSA key pair is generated.
On election day, voters authenticate via face verification with challenge-response liveness detection — head rotation, nose-target tests, and anti-spoofing checks.
The voter's choice is encrypted using homomorphic encryption on the client side, then signed with the device private key before transmission.
Encrypted ballots are committed to a permissioned blockchain, creating an immutable, tamper-evident record of every vote cast.
Votes are aggregated in the encrypted domain using homomorphic operations. Threshold decryption (t-of-n) reveals only the final tally — never individual ballots.
Results are published alongside zero-knowledge proofs of correctness. Anyone can independently audit the tally without compromising voter privacy.
VoteChain was designed by cryptographers and security engineers following zero-trust principles.
Every component is auditable, vendor-independent, and battle-tested in production.
VoteChain uses homomorphic encryption to tally votes without ever decrypting individual ballots. Combined with threshold decryption (t-of-n trustees), no single party can link a vote to a voter. Zero-knowledge proofs allow public verification without revealing any private information.
We use a permissioned blockchain (Hyperledger) to anchor cryptographic commitments of every vote and system event. This creates a tamper-evident, immutable audit trail that can be independently verified. The blockchain does not store plaintext votes — only encrypted commitments and integrity hashes.
Our multi-layered approach combines: 1) government-ID linked voter enrollment, 2) CompreFace 1:1 face verification, 3) challenge-response liveness detection (head rotation, nose-target, position checks), and 4) device-bound ECDSA keys that cryptographically bind the session to the authenticated voter.
Yes. Every component of VoteChain — from the microservices and cryptographic libraries to the infrastructure tooling — is built on 100% open-source software. The platform is designed for full code auditability, ensuring transparency and trust without vendor lock-in.
Absolutely. VoteChain is built on a cloud-native microservices architecture with horizontal pod autoscaling (HPA), event-driven communication via message brokers, and distributed caching. It's designed to handle millions of concurrent voters with sub-second ballot submission latency.
