CDK-opgeth

Katana is built using the Agglayer CDK-opgeth stack. CDK-opgeth is natively connected to the Agglayer network, and is an OP Stack-style config built with ZK tech on Ethereum’s most widely adopted execution client, Geth.

CDK-opgeth-sovereign is connected to the Agglayer which uses the pessimistic proof, a novel ZK proof whose program logic is written in Rust and proven using the SP1 zkVM and Plonky3 proving system.
