What is Kroma ?

Kroma is a rollup-based Ethereum Layer 2 (L2) blockchain. It aims to develop a 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.

Key Features of Kroma

• Universal ZK Rollup: Aiming to develop a universal ZK Rollup based on the Optimism Bedrock architecture.
• Optimistic Rollup with ZK Fault Proofs: Currently operates as an Optimistic Rollup with ZK fault proofs.
