Introduction

zkLink develops zero-knowledge blockchain solutions for the Ethereum ecosystem. It's flagship zero-knowledge Layer-3 aggregator platform, Nexus, is designed to bridge the gap among different zk-Rollup Layer-2 ecosystems to reduce liquidity fragmentation while providing security and scalability via zk-Proofs. It also enhances performance and reduces the cost for trading dApps, while making zero security compromises by inheriting the security characteristics from Ethereum.

Key Highlights

  • Liquidity Aggregation. The zkLink rollup network consolidates Stablecoins, ETH, and various multi-chain tokens into a unified token, eliminating discrepancies across chains.
  • Hyperscaling, Upholding Ethereum-grade Security. zkLink App Rollups can achieve up to 1000+ TPS, and sub 0.001 USD transaction cost while maintaining Ethereum-equivalent security measures. This fuels DeFi growth for traders to new heights!
  • Multi-Chain, Cross-Rollup Abstraction. zkLink allows users to deploy with the language and tools you are familiar with, with access to numerous L1s and L2s. Trade and manage multi-chain tokens on one user interface, without the need for a cross-chain asset bridge.


Three different dApps have been built with the zkLink rollup solution, with more to come.

Sale Structure

Token Utility

ZKL functions as both the native utility token and the governance token for the zkLink protocol. Operating as a standard ERC20 token on ethereum, ZKL will also be made accessible across integrated Layer 1 chains and Ethereum Layer 2 rollups. The total supply of ZKL is capped at 1,000,000,000 ZKL tokens and maintains a non-inflationary model.


Prover Fee: ZKL acts as the primary payment token for the zero-knowledge proof generation service offered by provers. Within the zkLink App Rollup infrastructure solution, DApps pay prover fees using ZKL. Provers will need to stake ZKL to access the Proof Auction Market, and earn ZKL rewards upon successful completion of proof task. The Proof Auction Market is a smart contract that coordinates the zero-knowledge proving task price bidding process and manages the provers access, distribute the prover fees, and more. Provers play an essential role within the protocol, contributing the computational resource necessary to compute and generate the zero-knowledge proof for the off-chain transactions.

License Fee for Rollup Infrastructure: DApps utilizing the zkLink rollup solution (App Rollups) compensate the infrastructure license fee in ZKL to the zkLink DAO Vault. An alternative payment option includes future revenue sharing. The zkLink DAO maintains the flexibility to modify the pricing framework. App Rollups gather transaction fees or other fees from users to sustain ongoing business operations.

Governance: ZKL is the governance token for the zkLink protocol. ZKL holders possess the ability to participate in the governance of the protocol development by initiating and voting on the proposals.

Perks: ZKL enables access to advantages within ecosystem dApps, such as discounted trading fees and exclusive NFT minting opportunities. The specific perks are curated by zkLink DAO and supported by eco dApps through the DAO Vault to cover the initial license fees.

The ZKL token secures the protocol’s decentralization in the long term. It incentivises active community participation to provide the computational resources necessary to generate the zero-knowledge proof, and sustain the network operations.

Roadmap


Ecosystem

The zkLink ecosystem continues to grow with dApps across various categories: Order Book DEXs, NFT Marketplaces, gaming, RWA derivatives, and more. 

Currently 3 ecosystem applications are running on mainnet or testnet utilizing zkLink infrastructure:

  • ZKEX: Pioneering as the first omni-chain order book DEX that provides spot and derivatives trading without limits. ZKEX simplifies multi-chain trading by offering a simple, accessible order book to securely trade on multiple chains eliminating the need for cross-chain bridges or wrapped tokens.
  • zkJump: is a ZK-secured cross-chain bridge for native assets that eliminates the necessity for intermediate or wrapped tokens. Leveraging zkLink’s infrastructure, users can seamlessly bridge their multi-chain tokens within a unified user interface, saving the user clicks, time, and costs.
  • Openworld: Operating as a decentralized exchange, Openworld enables multi-asset trading (crypto, stock, bond, forex & cmdty) by anyone, anywhere, anytime. OpenWorld utilizes zkLink to address challenges related to transaction efficiency and liquidity fragmentation.

Simultaneously, the protocol integrates with industry solutions such as key developer tooling, cross-chain messaging protocol, wallets, oracles, decentralized identity, modular DA, shared sequencer, and more.
