Quick Take Starknet contributors Herodotus and StarkWare unveiled the Cairo Verifier. This system verifies proofs on Layer 2, bypassing the Ethereum mainnet. The Cairo Verifier aims to reduce verification costs and latency, facilitating the growth of Layer 3 chains on Starknet.

Starknet contributors Herodotus and StarkWare have unveiled what’s known as the Cairo Verifier, a system to verify cryptographic proofs on the Layer 2 itself as opposed to the Ethereum mainnet.

Cairo Verifier will let developers implement verifiable computations using STARK — a type of proof developed by Starkware — on Starknet Layer 2 so that apps running on Layer 3s can use them for security.

This, according to the developers, opens the door to Layer 3 application-specific blockchains on Starknet.

The verifier system will offer a cost-effective verification, addressing key challenges such as high verification costs and latency issues that may normally constrain the deployment of Layer 3 applications on Starknet.

“We have a working prototype of the Cairo Verifier, with an expected launch in the coming weeks,” said Herodotus co-founder Kacper Koziol.

How does it work?

Currently, the verification process on Starknet involves the ‘SHARP’ prover and verifier, which submits cryptographic proofs to L1 Ethereum. These proofs are then verified on L1, ensuring the security of Starknet-based dapps.

The system extends the security of STARKs to Layer 3s, enabling the verification of proofs on Starknet. This Cairo Verifier is seen as crucial infrastructure for L3s, enabling them to secure their operations through StarkNet. It is expected to roll out in the coming weeks.

Starknet contributors are working on creating a network of Layer 3 application-specific blockchains, each tailored to specific needs. These dedicated blockchains offer the flexibility to customize elements like hash functions and consensus mechanisms.
