# Kroma

\-- Universal ZK Rollup based on the Optimism Bedrock

Kroma aims to develop an universal ZK Rollup based on the Optimism Bedrock architecture. Currently, Kroma operates as an Optimistic Rollup with ZK fault proofs, utilizing a zkEVM based on Scroll. The goal of Kroma is to eventually transition to a ZK Rollup once the generation of ZK proofs becomes more cost-efficient and faster. Kroma is deployed on the Sepolia testnet for further testing and optimization.
