About Kroma
As Asia’s leading Layer 2 solution built on the Superchain, Kroma is the first OP Stack rollup with an active fault proof system utilizing zkEVM.
Kroma will transition to a universal ZK Rollup once the generation of ZK proofs becomes more cost-efficient and faster — using its original modular ZK backend library, Tachyon.
Kroma plans to push for gamified web3 experience backed by its strengths in gaming, consumer applications, Asia market, and technical capabilities for true universal web3 adoption.
