Introduction

 DeFi has driven the high gas costs of developers and traders away from Ethereum to new high-performance chains such as Binance Smart Chain, Polygon and Solana in recent years.

The world of crypto is being embraced as a multi-layered and multi-layered future, where users move between different chains and use a mixed bag of crypto-tokens to fulfill their diverse demands.

This prospect, while creating great value for DeFi, also brings with it many problems:

1. Fragmentation of liquidity: As next-generation ecosystems form heterogeneous silos with different consensus mechanisms, ledgers, and incompatible technologies, it is difficult for users to hold assets on separate chains or trade between separate chains, resulting in higher usage rates. Capital is low. This in turn increases the cost of chains and new projects to attract users. 2. Difficulty of navigation: Currently, when a trader wants to exchange tokenA on chainA for tokenB on chainB, they usually have to first exchange tokenA for a stablecoin on a local DEX before finally exchanging the stablecoin. slow, find a bridge to transfer it to chainB. tokenB. This lengthy process takes considerable time and effort, involving multiple networks and gas costs. In addition, poor user experience of cross-chain transactions often reduces the enthusiasm of users and traders to use innovative projects and applications. 3. On-chain security: The biggest technical challenge in on-chain interoperability is protecting asset security during on-chain communication, which is vulnerable to many possible hacks or errors. Most on-chain interoperability protocols use a multi-sig (a group of nodes in a POS network) to verify changing states and cross-chain state, which assumes security based on POS network token values.

What is zklink? zkLink is a business-focused multi-chain L2 network whose integrated liquidity is secured by ZK-Rollups. The zkLink protocol solves these problems by creating a Layer2 network that connects different blockchains and Layer2 protocols by ZK-Rollup technology, where any valid stablecoin or LP stablecoin share can be pledged. and integrated into a unique design. The disparity of stablecoins (such as USDT and USDC) and origins (such as USDT from Ethereum and Solana) has been removed, and multiple use cases can safely benefit from the liquidity accumulated in the zkLink Layer2 ecosystem. The zkLink ecosystem connects different L1 chains and L2 networks, enabling developers and traders to leverage integrated liquidity from isolated chains with a secure and seamless user experience, contributing to a more accessible and efficient DeFi ecosystem for all.

zkLink creatively

It uses zero-knowledge technology for multi-chain interoperability with a trustless and decentralized power separation design that protects the security of assets and transactions as well as multi-chain data transmission. In addition, zkLink removes the disparity between stablecoins from different blockchains and different types, and achieves multi-chain liquidity pooling to create a massive stablecoin liquidity pool through a unique protocol-controlled debt (PCD) mechanism. and provide an efficient and affordable capital. and infrastructure with easy access.

Features of zklink Zero knowledge credentials with zero security flaws

Zero knowledge credentials are mathematically validated to guarantee the execution of valid transactions. And they cannot be tampered with or forged, thus guaranteeing the security of the funds.

Due to the availability of ZK-Rollup chain data, account statuses can always. Restored in case of attacks, even when all data in the zkLink Layer2 engine is destroyed.
Zero knowledge ensures that no one, including the platform itself, can upload a fake zk_proof to the main chain. 

Aggregation of native assets from multiple chains

dApps built on zkLink's L2 network of integrated multi-chain liquidity. With rapid deployment solutions for decentralized, non-custodial order book, AMM, derivatives, and NFT exchanges.

A unified currency for all purposes in the zkLink L2 ecosystem.
No need for multiple wallets for separate chains.
Minimum friction and finalization time 

Current version

A multichain ZK-Rollup network
Connect EVM compatible chains
AMM multi-chain demo
Multi-chain order book demo
Support atomic swap

the future

Enhancement of atomic swap to support more complex use cases like derivatives etc
Support decentralized zero knowledge credentials
Integrate oracles into zkLink L2 

last word

zkLink is a business-focused L2 ecosystem that solves liquidity problems. A growing number of permissionless L2 liquidity solutions provide on-chain dApps developers with diverse use cases and easy-to-deploy APIs. In the zkLink L2 ecosystem, there will be no boundaries between individual chains and decentralized local liquidity will be aggregated. zkLink structure
