What is QuarkChain (QKC)?
QuarkChain is a Layer 1 blockchain designed to solve the Blockchain Trilemma: scalability without sacrificing decentralization and security. With a two-layer architecture and sharding, the platform aims for the ability to handle over 1 million TPS while being multi-virtual machine compatible, facilitating the deployment of dApps, DeFi, NFTs with high performance and optimal costs.
The project is built by a team of experienced engineers at Google and Facebook, committed to providing a flexible, robust, and accessible development environment for Web3.
How does QuarkChain (QKC) work?
QuarkChain applies a two-layer blockchain architecture: the Shard Chains layer operates multiple parallel subchains with diverse consensus mechanisms such as PoW, PoS, PoSW; the Root Chain layer validates shard blocks, protecting the network with the total hash power of the entire system.
At the same time, the platform supports multiple virtual machines including EVM, enabling Ethereum dApps to easily migrate, and aims to integrate additional VMs like EOS VM. Sharding technology helps linear scaling, increases throughput without affecting gas fees or causing network congestion.
QuarkChain is striving to build a scalable blockchain ecosystem capable of reaching millions of TPS while still maintaining decentralization and security, which many current blockchain projects have not achieved.

QuarkChain Products
Developer Portal & SDK
Developer Portal is the technical platform for developers to build dApps on QuarkChain. It provides complete technical documentation, multi-language SDKs, APIs, along with a testnet and faucet environment to support effective testing.
Supports EVM and plans to expand integration with other virtual machines like EOS VM, making it easier for projects to migrate dApps from Ethereum and diversify compatibility.
QPocket
QPocket is the official wallet of QuarkChain, supporting the storage of QKC and many other tokens on the multi-chain network. The wallet allows asset management, staking, and direct interaction with dApps in the ecosystem, ensuring high security, easy backup/recovery on mobile devices.
QPool
QPool operates a mining and staking model based on the PoSW mechanism combining PoW and staking, helping to optimize security, ensure fair token distribution, and reduce hardware requirements for participants. Users receive an average staking reward of about 27% APR, creating a stable passive income.
Outstanding features of QuarkChain
Outstanding scalability with over 1 million TPS thanks to shard chains.
Optimized decentralization, using many low-cost nodes to reduce operational costs.
High safety with network protection by 50% of total hash power, preventing double spending attacks.
Supports cross-segment transactions, shortening confirmation time to just a few minutes.
An incentive system based on game theory to balance hash power distribution.
Overview of QKC Token and Tokenomics
The QKC token is the main utility token for the QuarkChain ecosystem with a total supply of 10 billion QKC, of which over 7 billion tokens are in circulation. The token is used to pay gas fees, stake to secure the network, and reward miners, validators.
Detailed Information Token Name QuarkChain Symbol QKC Blockchain QuarkChain Contract 0xea26c4ac16d4a5a106820bc8aee85fd0b7b2b664 Token Type Utility Token Total Supply 10,000,000,000 QKC Circulating 7,126,569,891 QKC
Wallet & Exchange
Users can store QKC on popular wallets like MetaMask (ERC-20), QPocket, Coin98, Trust Wallet, Ledger… QuarkChain is also listed on major exchanges such as Binance, OKX, Bitget, Gate.io, facilitating trading and liquidity.
Roadmap
QuarkChain has proposed migrating from Layer 1 to Ethereum Layer 2 using OP Stack, with a community voting result of 100% approval in May 2025.
The migration plan includes deploying a new ERC-20 Token contract, maintaining a total supply of 10 billion QKC, building an official bridge on Ethereum, and applying many modern technical features such as Soul Gas Token, Parallel EVM Execution.
Integrating OP Stack on Ethereum Layer 2 will help QuarkChain scale the network quickly, improve the trading experience, and develop a more comprehensive Web3 ecosystem.
