ZK-STARK Proof Engine

Minerva

Prove truth. Reveal nothing.

The world's first accessible ZK-STARK proof engine. Generate real zero-knowledge proofs in your browser.

The Foundation

What is Zero-Knowledge?

Zero-knowledge proofs let one party prove a statement is true — without conveying any information beyond the validity of that statement itself.

Privacy

Prove a claim without revealing the evidence. Your data stays yours — only the proof is shared.

Trust

Mathematical certainty, not institutional promises. A valid proof is provably correct — no authority required.

Speed

Client-side WASM proofs in milliseconds. Verification is fast, deterministic, and requires no server round-trip.

Capabilities

Why Minerva?

Real cryptography. No shortcuts. Designed for developers who need production-grade privacy primitives without the research overhead.

01 — Cryptography

Real STARK Proofs

Not hashing tricks. Winterfell-powered cryptographic proofs with FRI commitments and polynomial evaluations over binary extension fields.

02 — Privacy

Client-Side by Design

Proofs generate entirely in your browser via WebAssembly. Your private data never leaves your device — not in transit, not in logs.

03 — Accessibility

No PhD Required

Other ZK tools demand deep cryptographic expertise. Minerva abstracts the complexity so developers and businesses can ship without a research background.

04 — Intelligence

Juno Oracle

Our AI assistant generates circuits from plain English. Describe what you want to prove; Juno builds the circuit, selects the template, and configures the parameters.

05 — Portability

One Engine, Every Platform

Rust core compiles to native CLI, WASM, and server-side binaries. Integrate into web apps, backend services, or run standalone from the terminal.

06 — Production

Ready to Deploy

Ten validated circuit templates spanning compliance, finance, identity, supply chain, and auditing — tested, documented, and ready for integration.

The Stakes

Where ZK Proofs Were Missing

These incidents were architectural failures — institutions collecting data they didn't need, systems built on disclosure instead of proof.

2017

Equifax Data Breach

147 million records exposed

A vulnerability in a web application framework exposed Social Security numbers, birth dates, addresses, and credit history for nearly half the US adult population.

With Minerva: A credit check becomes a single proof — "score exceeds threshold X" — with zero transmission of the underlying score, SSN, or personal data.

2020

Wirecard Financial Fraud

€1.9 billion that never existed

Wirecard reported €1.9 billion in escrow accounts that auditors could not verify. The fraud persisted for years.

With Minerva: ZK-STARK audit proofs let regulators cryptographically verify that reported balances match real positions — without accessing customer data.

2018

Cambridge Analytica

87 million profiles harvested

A personality quiz app scraped the data of 87 million Facebook users without consent, then sold psychographic profiles for political targeting.

With Minerva: Users prove eligibility for an ad segment — age, interests, location — without revealing any personal data. Targeted advertising without surveillance.

2016

The Panama Papers

11.5 million documents leaked

The largest data leak in history exposed offshore financial structures used to evade taxes.

With Minerva: Tax authorities verify compliance without accessing private records. A ZK proof demonstrates "tax obligations met" without revealing account balances.

2021

COVID Vaccine Passports

Global privacy vs. public health

Vaccine passport systems worldwide required presenting medical records, identity documents, and date of birth — far more than needed.

With Minerva: A single ZK proof attests to vaccination status without revealing medical history, date of birth, identity, or any other personal data.

The Process

How It Works

From natural language to a cryptographic proof in three steps.

Step 01

Describe what you want to prove

Tell Juno Oracle in plain English. No circuit knowledge required.

"Prove my annual income exceeds $75,000 without revealing the exact amount"

Step 02

Juno generates your circuit

Juno selects a template, configures parameters, and returns a MinervaFormat circuit definition.

{ "circuit": "income_compliance", "version": "1.0", "params": { "threshold": 75000, "currency": "USD" }, "visibility": "private" }

Step 03

Generate & share your proof

The WASM engine runs client-side. Your proof is shareable, verifiable, and contains zero private data.
