What is ZKCross? ZKCross is a platform that provides security, multi-chain connectivity, and high scalability using Zero-Knowledge (zk) technology. The ZKCross platform uses the WebAssembly virtual machine (WASM), also known as zkVM, which allows Web2 developers to code in their preferred high-level programming languages, such as C, C++, Rust or Python .
ZKCross is one of two projects in the Infrastructure segment that won the MVB VI competition organized by Binance Labs.

What is ZKCross?
Overview of ZKCross
ZKCross is a platform that provides security, multi-chain connectivity, and high scalability using Zero-Knowledge (zk) technology. The ZKCross platform uses the WebAssembly virtual machine (WASM), also known as zkVM, which allows Web2 developers to code in their preferred high-level programming languages, such as C, C++, Rust or Python .
ZKCross is completely decentralized through the use of zk-rollups, is a Layer 2 scaling solution that bundles and processes multiple off-chain transactions before sending a single transaction on-chain to increase transaction throughput and reduce fees. DEnsuring decentralization by providing on-chain valid proof, preventing malicious operators or corrupting the chain.
Fusion SDK provides easy-to-use APIs for developers to build hybrid contracts and applications. Developers can easily access on-chain accounts and states and synchronize messages with each other or with on-chain smart contracts.
Mechanism of action
Structure
Zk-Shadow Layer
Zk-Shadow Layer is a single layer that connects on-chain and off-chain environments seamlessly. This layer facilitates the connection between zkWASM and the on-chain layer via zk-proxy contracts. This therefore breaks down the barrier between Web2 and Web3 while facilitating high throughput and accessibility for any user or developer.
The zk-Shadow layer uses Zero-Knowledge Proof-Of-Stake (zkPoS) as the protocol consensus method, where users must hold a specific amount of ZKC tokens to participate as validators. The lead zk node is selected based on the size of its ZKC stake, reputation, and historical performance. The zk proof is sent to the zkproxy contract before being posted on the supported blockchain network, allowing for multi-chain execution.
The zk-Shadow layer helps reduce data costs on the main blockchain network and the costs associated with executing smart contracts and transactions on the main chain. By simulating the execution of smart contracts and transactions off the main blockchain network, state updates from these off-chain computations are validated through zk proofs, creating a secure bridge between off-chain and on-chain events in a decentralized application.
The zk-Shadow layer has several potential use cases including decentralized finance (DeFi), supply chain management, gaming, and healthcare.
ZkVM
zkVM uses zk-SNARK, A cryptographic proof allows one party to prove to another party a particular piece of information without revealing any information about it. SNARKs provide a way to validate calculations on the blockchain without exposing sensitive (personal) data.
Advantages of zkVM:
- High flexibility: With zkVM, developers can write smart contracts in their preferred high-level programming language, C/C++, Java or Python, instead of being limited to programming languages specifically.
- Improved scalability: zkVM enables faster transaction execution and higher throughput, essential for building scalable decentralized applications.
- Saw Modularity and Composability: With zkVM, developers can quickly build complex decentralized applications using different modules without worrying about language compatibility issues or platform.
- Advanced security: zkVM uses ZK proofs, called SNARKs, to provide high security by allowing computation verification without revealing sensitive data.
- Decentralization: zkVM promotes decentralization by allowing the execution of smart contracts in a distributed manner across multiple nodes, thus eliminating the need for central authorities.
Mechanism of action of ZKCross
When users interact with dApps built on WASM. The dApps will then send the contract to zkNodes on the Shadow Layer. On Shadow, transactions will be simulated as well as processed Off-chain, while zkNodes will synthesize and generate a zk proof to prove the validity of contract execution, posted to the zkProxy contract. The zk proof is sent to the zkproxy contract before being posted on the supported blockchain network, allowing for multi-chain execution.
The product is built
- OmniSwap: Is a decentralized exchange built on the execution layer of ZKCross. Supports swapping tokens on any blockchain to another token. The first Dex Crosschain built on Layer 2, helping users enjoy cheap transaction fees on Layer 2 but can exchange assets belonging to Layer 1.
- ZkGame: ZKCross’ Fusion Platform leverages advanced fusion technology to help Games gain access to all assets and users across all chains.
- ZkPaaS: Provides an effective solution to solve data-related problems by implementing zkWASM. It reduces on-chain data and improves the scalability and decentralization of the blockchain.

Summary
ZKCross offers a very viable solution for multi-chain communication environments and uses zk proofs to help reduce data on-chain and increase security. As a Layer 2, users will enjoy extremely cheap fees. In addition, ZKCross uses WSAM to create a friendly environment as well as favorable conditions for Web 2 developers to participate in Web 3.
On the other hand, ZKCross is also facing a few minor limitations, which is that the transaction speed is still slow, only reaching 1 TPS. At this speed, it is faster than bridges like Orbiter and L2, but still slower than Dex Crosschains like Hashflow, Stargate, and Portal Bridge. The problem is that in order for users to interact with ZKCross, they need to transfer money to L2, so it is a bit more complicated.
So I have clarified what ZKCross is? ZKCross cryptocurrency overview. Hope this article brings you a lot of useful knowledge!
