The relationship between Katana and Succinct In fact, I had no interest in Katana at all, but I learned a bit about it after @SuccinctLabs shouted out the launch of the @katana mainnet. First of all, Katana is a DeFi-specialized L2 that is an Ethereum optimistic rollup built using Optimism's OP Stack. You might wonder what the relationship is between an OP rollup and Succinct, which creates ZK proofs? Succinct has a technology called OP Succinct. This is an open-source solution that allows existing Optimistic rollups to operate like ZK rollups. Realistically, implementing a chain as a ZK rollup from the start is quite challenging. Achieving a zkEVM that is fully compatible with EVM is very difficult, and proof generation is slow and expensive. Therefore, Katana has already chosen infrastructure that is mature, with many L2s like Base and OP, and has created a chain using the OP Stack, which allows for easy and quick network creation (it can even be done with a simple click). Then, through OP Succinct, it introduced ZK's validity-proof instead of the biggest drawback of optimistic rollups, which is fraud-proof, thereby enhancing security. Moreover, the heavy and costly task of generating ZK proofs can be delegated to the Prover network that Succinct will launch, significantly reducing costs. In this way, Succinct is not just researching and developing zkVM as open-source but is also providing tools targeted at actual demand sources like L2s and creating an environment where costs can be reduced through the Prover network, attempting to expand the ecosystem.
