WHAT IS ZKCROSS

WHAT IS ZKCROSS

A ZK-based Fusion Platform allows developers to build Web3 applications while benefitting our fusion model seamlessly.

Shadow execution layer

An environment for off-chain contracts to live and process transactions that interact with those contracts.

zkWasm

A virtual machine that can execute code written in general-purpose programming languages. zkProof will automatically be generated along with code execution and be posted to L1/L2 chains for verification.

Advantages

Revolutionary Fusion Platform that enables decentralised applications to support a broad set of blockchains.

Easy to use

Accessible to developers who want to adopt zero-knowledge proof to develop Web3 applications.

High performance

Resource-efficient execution with efficient computation and storage resources.

Extreme safe

Secure state synchronization across different blockchains with zero-knowledge proof

Transparent

Trustworthy communication for on-chain and off-chain scenarios

Developers

ZKCross is developing a fusion platform using cutting-edge technology. This platform includes a shadow execution layer and zkWasm to facilitate on-chain and off-chain interaction using Zero-Knowledge Proof (ZKP). Developers can easily and quickly build applications using the Fusion SDK and other developer components.

Fusion SDK

The fusion SDK provides easy-to-use APIs for developers to build hybrid applications and contracts. Developers can easily access on-chain accounts and states and sync messages with each other or on-chain smart contracts.

Shadow execution layer

The shadow execution layer is an environment for off-chain hybrid applications/contracts to live and process transactions that interact with those applications/contracts.

State Aggregator

The aggregator is a universal firmware that synchronizes and rollup states between off-chains and smart contracts on different blockchains. It can be used as an off-chain/multichain trust communication framework.

zkProxy

The Hybrid contract framework's on-chain component can be utilised by smart contracts to access off-chain computation and resources. This integration includes a built-in zkProof verification mechanism that simplifies the complex task of verifying off-chain activities.

The most secure shadow execution layer

DEFI

OmniSwap

Visit

Omniswap is a decentralized exchange built with ZKCross's execution layer. It benefits from the agility provided by ZKCross, which support swap token on any chain for another token. The process is very lightweight; from the user's perspective, it's intuitive to move their fund among blockchains without worrying about any loss.

Crypto native game

zkGame

Web3 Games are a highly sought-after blockchain use case, yet many centralisation problems are prevalent. Typically, these games rely on NFTs to anchor in-game assets to the blockchain while their central servers handle the core game mechanics. ZKCross's Fusion platform leverages its state-of-the-art fusion technology to provide a resource-efficient resolution to this problem.

Off-chain computing

zkPaaS

As demand for blockchains increases, the volume of on-chain transactions grows, causing scalability and decentralisation challenges due to a large amount of data that needs processing. ZKCross offers an efficient solution to this issue by implementing zkWASM, which reduces on-chain data and improves blockchain scalability and decentralisation.

FAQs

A ZK-based fusion platform for developers to build Web3 applications in a fusion model.
A fusion contract or application combines smart contracts running on the L1 or L2 blockchains(on-chain) and code running outside the blockchain(off-chain), the on-chain and off-chain contracts can share a global state, invoke each other, and communicate in a trustless way.
Smart contracts are running on top of the L1 or L2 blockchains.
Smart contracts run in ZKCross's zk-Shadow layer instead of the L1 blockchains.
Aggregated state of both on-chain and off-chain states.
After any contract function is executed, a zkProof will be autogenerated and posted along with the result.
The environment for off-chain contracts to live and process transactions that interact with those contracts.
A virtual machine that can execute off-chain contracts written in general-purpose programming languages. zkProof will automatically be generated along with code execution.
