How Does StarkEx Work?

User transactions are processed by the operator (e.g, an exchange) and are sent to the StarkEx service. StarkEx validates the transactions in two steps: Parallel stateless validations (such as formatting and value ranges) and then sequential validations considering their context.

The StarkEx service batches the validated transaction into a batch, and the relevant balances are updated.

The StarkEx service generates a STARK proof, attesting to the validity of the transactions in the batch, and sends the proof on-chain.

An on-chain Verifier smart contract receives the STARK proof. Once the proof is verified, a commitment to the new balance states are stored on-chain.

The Essence of StarkEx

Validity Proofs

StarkEx Validity Proofs ensure that only valid data, resulting from computations performed with integrity, is committed on-chain.

Massive Scale

The secret to StarkEx’s massive scaling capabilities lies in the uneven division of computation between its off-chain Prover and the on-chain Verifier.

Self-Custody

StarkEx powers self-custodial dApps, and employs innovative anti-censorship mechanisms to ensure that users’ funds always remain in their custody.

Data Availability (DA) Spectrum

StarkEx has been developed to serve a diverse range of user and application needs.

General Computation

StarkEx is powered by Cairo, our expressive and highly performant ZKP programming language. Cairo allows StarkEx to support any business logic.

Battle-Hardened

StarkEx has been in production on Mainnet since June 2020.

Time to Market

Applications that wish to integrate with StarkEx can arrive on Mainnet within a few weeks time, depending on the maturity of their off-chain Operator node.

Privacy

ZK-STARK, as a zero-knowledge proof system, can provide a user with complete privacy, not only from other users, but also from the Operator.
