HashKey Group, a leading digital asset management firm, has officially launched the mainnet of HashKey Chain, its self-developed Ethereum Layer2 public chain. This launch marks a significant milestone in the development of the Ethereum ecosystem, as Layer2 solutions are widely anticipated to improve the network's scalability and efficiency. The launch of HashKey Chain's mainnet follows an extensive testing phase, during which the testnet attracted over 860,000 registered wallet addresses and processed 24.72 million transactions from 300,000 participating community members. A total of 50 projects were deployed during this phase, showcasing the strong interest in HashKey Chain's Layer2 solution. HashKey Chain is designed to address the challenges faced by Ethereum, such as high transaction fees and slow transaction speeds. It utilizes a Proof-of-Stake (PoS) consensus mechanism and a novel sharding architecture to achieve high throughput and low latency. The platform also supports smart contract functionality, allowing developers to build decentralized applications on top of HashKey Chain. With the launch of its mainnet, HashKey Chain is now open to developers and users. The project team is actively working on expanding the ecosystem and developing new features for the platform. It is expected that HashKey Chain will play a significant role in the future of the Ethereum ecosystem, enabling wider adoption and innovation.
