Fox is an Ethereum zkRollup using ZK-EVM and its original ZK-FOAKS technology. ZK-STARKS comes from Zero Knowledge - Fast Objective Argument of Knowledges that is faster than Stark with linear proof time, sublinear verification time, transparent, and proof recursion inside.

Fox is building a zkRollup that is fully EVM compatible, for the convenience of Solidity contracts deployment. We will support direct validation of the Ethereum block with a concise validity proof approach called ZK-FOAKS.

The basic idea of ZK-FOAKS will be elaborated on below. It verifies the consistency and integrity of each opcode in the EVM execution trace, then sends the state proof and validity proof by Double-Deck Express, with the low-gas, high-secure Ringer contract to deal with the data availability. In this way, L1 smart contract can migrate seamlessly to Fox. Instead of using the new ZK-friendly primitives, we'll build reversely. We'll use custom optimizations to support native EVM. This gives us a huge advantage of being compatible with all existing Ethereum infrastructure without any modifications.

Given the EVM opcode compatibility, ZK-FOAKS is designed to verify state changes efficiently. It promises not only to be secure and efficient but also to accomplish competitive decentralization. In an effort to achieve high-speed proving and succinct proofs for quick verification, the Fox team is focused on the optimization of ZK-FOAKS.

The Fox network is permissionless, decentralized, secure, efficient, and comes with verifiable block data. Development efforts aim at permissionlessness, that is, allowing anyone to participate in the network. For instance, the consensus algorithm will give everyone the opportunity to be a Sequencer, an Aggregator, or a hardware accelerator.

Data availability is most crucial for decentralization, where every user has sufficient data needed to rebuild the full state of a rollup based on the decentralized storage that has got the best configuration for data availability. The aim is to ensure that there is no censorship and that no one party can control the network.

As an L2 solution, most of the Fox security is inherited from Ethereum. Smart contracts will warrant that anyone who executes state changes must do it correctly. ZK-FOAKS creates a proof that attests to the validity of a state change, and avails validity proofs on-chain for verification.
