What is zkLink and what problems does it solve?
zkLink is a multi-chain infrastructure solution for high-performance ZK applications. zkLink’s flagship Layer 3 solution, Nexus, is based on zero-knowledge technology that aims to empower the next generation of decentralized trading products by improving performance while reducing the costs of trading DApps such as order book DEXs, AMMs, NFT marketplaces, and more.
zkLink solves the problems related to liquidity fragmentation, multi-chain DApp deployment composability, blockchain navigation complexity and lastly, cross-chain transaction security. Using our SDK and zkSNARKS, zkLink connects various Layer 1 and Layer 2 ecosystems together, enabling native DeFi assets on distinct ecosystems to communicate between each other. This allows developers to easily facilitate multi-chain activity and DApp deployments in an efficient and secure manner.
How does zkLink ensure the security and privacy of user transactions?
The straightforward answer here is zero-knowledge-proof technology, in which our protocol employs zk-SNARKs to shield transaction information. While transactions are verified and recorded on the blockchain, details like sender, recipient, and transaction amount remain private.
In comparison to a classic ZK-Rollup architecture, zkLink employs a new type of ZK proof that simultaneously deploys the rollup contracts on multiple L1 blockchains and L2 networks at the same time. zkLink sends ZKPs to the Layer 2s who then submit the ZKPs to Ethereum, which are then verified by Ethereum smart contracts. Therefore, the transaction finality on a zkLink Nexus L3 rollup is ultimately achieved on Ethereum, which is widely recognized for its security guarantees. This is why we’re called a multi-chain ZK-Rollup.
How does zkLink simplify the user trading experience?
zkLink offers interoperability by facilitating seamless token transfers across different blockchains and ZK-Rollup Layer 2s, eliminating the need for users to navigate complex processes when trading on multiple platforms. zkLink also provides a unified platform that aggregates liquidity from various chains, allowing users to access broader pools of liquidity and engage in more efficient trading experiences without worrying about slippage.
Value Proposition of zkLink & Metis integration
-
Multi-Chain Interoperability
dApps developed on zkLink’s TS-zkVM or future TS-zkEVM will be able to seamlessly transact on Metis, leveraging assets from any other integrated chains on zkLink. -
Lower Costs
zkLink creates liquidity pools on every integrated chain. For regular token deposits and withdrawals, zkLink optimizes costs by executing orders in batches, resulting in significantly lower withdrawal costs per transaction. This cost-efficiency enhances the overall economic attractiveness of utilizing Metis and zkLink for decentralized trading.
