#### StarkEx is StarkWare’s Layer-2 scalability engine, which now powers DeversiFi.

DeversiFi is the first self-custodial exchange to launch with the StarkEx technology

StarkEx leverages the STARK zero-knowledge proof technology to bring scalable non-custodial trading to cryptocurrency exchanges.

There are a few properties to Zero-Knowledge Proofs, and STARKs in particular, that make them a powerful tool for blockchains. These properties are built into StarkEx:

- The inherent asymmetry between the prover’s and verifiers’ computational load can be put to good use: a native computation on the blockchain, such as a batch of transactions, can be moved off-chain, where a prover can validate them and generate a corresponding proof. This proof is then sent back to the blockchain where a verifier smart contract can verify its correctness in exponentially less time. This methodology is the foundation for ZK-Rollups (ZKR) - see more here
- This benefits DeversiFi, in real-terms, by allowing for more transactions to be handled per second (9000+) resulting in both faster trading speeds/capability and much lower trading fees born from a reduction in gas costs.

- The absence of trust assumptions in STARKs means that the state of the system is mathematically and cryptographically guaranteed. There are no additional assumptions to those presented by permissionless blockchains (e.g.Ethereum).
- The Zero-Knowledge component will allow transaction details to remain private not only from third parties (e.g. competing traders), but also from the StarkEx operators - DeversiFi and StarkWare.
