Introducing the Cairo Verifier for Layer 2 Security
Starknet contributors Herodotus and StarkWare have developed the Cairo Verifier, a system that allows cryptographic proofs to be verified on the Layer 2 itself instead of relying on the Ethereum mainnet. This innovation enables developers to implement verifiable computations using STARK on Starknet Layer 2, enhancing security for apps running on Layer 3s.
The Cairo Verifier specifically addresses challenges such as high verification costs and latency issues, which can hinder the deployment of Layer 3 applications on Starknet. By overcoming these obstacles, it paves the way for the expansion of Layer 3 application-specific blockchains on Starknet.
How Does It Work?
The current verification process on Starknet involves the ‘SHARP’ prover and verifier, which submit cryptographic proofs to Ethereum’s L1. These proofs are then verified on L1 to ensure the security of Starknet-based dapps.
The Cairo Verifier extends the security of STARKs to Layer 3s, enabling the verification of proofs directly on Starknet. The launch of the Cairo Verifier is expected in the coming weeks, according to Herodotus co-founder Kacper Koziol.
Starknet contributors are also working on creating a network of Layer 3 application-specific blockchains, each customized to meet specific requirements. These dedicated blockchains offer flexibility in terms of elements like hash functions and consensus mechanisms.
Hot Take: Advancing Security and Flexibility for Layer 3 Applications
The introduction of the Cairo Verifier marks a significant step forward in improving security and expanding opportunities for Layer 3 applications on Starknet. By allowing cryptographic proofs to be verified directly on Layer 2, developers can enhance the integrity and reliability of their apps while mitigating the challenges associated with verification costs and latency.
