QuarkChain is a decentralized blockchain project designed to address the challenges of scalability, security, and decentralization. Its primary goal is to provide a high-capacity peer-to-peer transactional system capable of supporting commercial-level applications. The project is built on a two-layered architecture that consists of an elastic sharding layer and a root blockchain. The sharding layer contains multiple smaller blockchains, known as shards, that process transactions in parallel. The root blockchain serves to confirm the blocks from these shards, ensuring the security of the entire network. A core feature of the network is its use of heterogeneous sharding, which allows each shard to operate with different consensus mechanisms, ledger models, and virtual machines. This flexibility enables the network to cater to various industrial requirements within a single infrastructure. QuarkChain employs a unique consensus mechanism called Proof of Staked Work. This system combines elements of proof of work and proof of stake, allowing miners who stake tokens to mine with reduced difficulty. This approach is intended to distribute hash power more evenly and prevent the centralization of mining resources. In its more recent evolution, QuarkChain has shifted its focus toward becoming an Ethereum Layer 2 solution. This strategic transition aims to enhance the Ethereum ecosystem by providing modular infrastructure and AI-ready capabilities. This vision, referred to as the Super World Computer, integrates high-speed execution with on-chain verifiable storage. The project is actively involved in developing solutions for data-intensive applications, such as artificial intelligence and machine learning, by providing decentralized storage proofs. The project also introduced innovations like the Soul Gas Token to streamline transaction fees across its sharded environment and has proposed upgrades to improve developer flexibility by removing certain contract size limits. It maintains compatibility with the Ethereum Virtual Machine, allowing developers to migrate decentralized applications easily. The QKC token serves as the native utility token within this ecosystem. Its primary functions include being used as a currency for transaction fees, providing incentives for miners and community members who contribute to the network, and participating in governance decisions. By allowing for efficient cross-shard transactions and a simplified account management system, the project aims to offer a user-oriented experience for various Web3 use cases, including gaming, social media, and high-frequency trading.
