zkLink : A Multi-chain Rollup Infrastructure Based on Zero-Knowledge Technology
🫐Hi dear readers :) , today i'm going to share my research about zkLink Project with you.
🪶zkLink is a protocol that multi-chain rollup infrastructure based on zeroknowledge technology. zkLink adress the challenges of blockchain interoperability and standardization by building a multi-chain rollup infra protocol to simplyfy multi-chain dApp deployment and resolve liquidity fragmentation. It leverages zero-knowledge proof technology to provide a high throughput , low cost App Rollup deployment solution.
For zkLink documantation article ; there are some unforseen challenges on multi-chains and multi-layers ;
- Liquidity fragmentation
- Multi-chain product deployment challange
- Navigation complexity and high cost
- Security risk during inter-chain transaction.
zkLink want to solve these challanges with innovations.
🪼Let's get in some technical information :)
We have to know working principals and stages of multi-chain zkRollups . These are commit, prove, execute and synchranize (for multi-chain zkRollups).
Besides this ; typical blockchain network has four main things ; execution , settlement , consensus and data avalibility .
- Settlement Layer of zkLink
zkLink has two main settlement provider .
- A zkLink Nexus L3 rollup settles the transactions and transition of states directly on Ethereum's ZK-L2s, and the L2s settle on Ethereum. Hence the finality of the transactions on a zkLink Nexus L3 rollup will be ultimately achieved on Ethereum layer1.
- A zkLink Origin rollup will settle the transactions and transition of states on Ethereum, ALt-L1s, OP-L2s, and ZK-L2s, corresponding to the actual networks connected, as long as one of the networks supports zk-SNARKs proof verification, and there is a secure and fast way to achieve states synchronization across the networks.
- Execution Layer of zkLink
zkLink is planing to use TS-zkVM to provide execution . The TS-zkVM is a high-efficiency ZKP execution environment specifically designed for high-performance financial products such as CLOBs, and it is constructed by zkLink. TS-zkVM extends and integrates.
- Sequencer Layer for zkLink
The sequencing layer is a pivotal component in rollup systems, primarily responsible for receiving user transactions, sequencing the transactions and bundling them into batches. These batches are then committed to the settlement layer. zkLink protocol aims to incorporate decentralized sequencer solutions. These solutions, including platforms like Espresso, Astria, and Fairblock, aim to mitigate centralization risks by processing and validating transactions across a distributed node network. This strategy will not only boost network security and transparency but also strive to offer a more secure, equitable, and efficient rollup solution to its users.
- DA Layer for zkLink
Both zkLink Nexus and zkLink Origin by default support the primary chain as the DA layer.
Secondly, both Nexus and Origin support Validium, which involves an external DA solution. zkLink will integrate various third party modular DA solutions, such as Celestia, EigenDA, Avail, etc., to meet diverse demands from developers.
------------------------------------------------------------------------------------------------
With all these actions and innovations and by harnessing the potential of zero-knowledge proof technology , the main functions of the zkLink protocol are planned to be ;
- Multi-chain liquidity aggregation across L1 blockchains and L2 rollups.
- Quick multi-chain product deployment with SDK and APIs
- A trading-specific-zkVM ,empowering high-troughput , low cost App Rollup splution for high performance financial applicaitons such as Order Book DEX .
🧩By the way , Pre-sale of zkLink native token (ZKL) will be held soon . If you're interested it , you can check this link . Also ı'm planing to read article about this sale :) stay tuned !
