StarkWare Announces Cairo Verifier for Layer-3 Scalability in Blockchain Ecosystem

According to CoinDesk, StarkWare, the developer behind the Starknet blockchain, announced the upcoming launch of a new 'Cairo Verifier' in the next few weeks. This development will open the door to layer-3 application-based chains on Starknet. Cairo, a collaborative effort between StarkWare and another developer, Herodotus, is a crucial technology that verifies proofs and posts them back to the layer-2 blockchain, instead of Ethereum's mainnet. A StarkWare representative stated in a Telegram message that the tool is 'designed to bridge the crucial gap to layer-3 scalability in the blockchain ecosystem.' The new component will enable the verification of proofs from layer-3 chains on layer-2s, which was previously not possible, according to StarkWare. The Cairo verifier will reduce costs associated with verifying these proofs and speed up transaction confirmation times (known as latency). Cairo will be at the core of verifying storage proofs on layer-2s and layer-3s. Storage proofs are a type of cryptographic feature that allows users to 'prove' that certain transactions or assets exist on other chains without relying on a third party. StarkWare and Herodotus developers have previously worked together to develop storage proofs on Starknet. StarkWare stated that 'the Cairo Verifier represents an evolution from previous verification technologies, offering improved capabilities tailored to the current demands of the blockchain ecosystem.'
