New Metis Rollup Tech Addressees Ethereum Scalability for Businesses
ReadSmart L2 still bundles and processes Ethereum transactions off-chain before returning them for recording and verification. However, the transaction data is stored off of both the layer 1 and layer 2 by using decentralized cloud storage service MEMO Labs. The address and transaction data is Merklized and stored on the base Ethereum blockchain for retrieval and verification later, saving space and making it faster for validators and fraud proofs to find and verify transactions. Metis has a fail-safe in place should MEMO Labs become unavailable for any reason, Sinelnikova said.
