Client background
Quai Network’s vision is to create a decentralized financial system with ultra-fast transaction speeds (up to 50k TPS) using an innovative Proof-of-Work blockchain. It offers scalable, censorship-resistant infrastructure, secure smart contract integration, and low-fee transactions while supporting DeFi and programmable finance.
Business challenge
The first was ensuring high scalability without compromising the principles of decentralization, which are essential for supporting an expanding user base. Another significant hurdle was the seamless integration with diverse blockchain standards like ERC-20 and ERC-721, ensuring compatibility and functionality across multiple token types. Secure transaction processing and wallet management were also paramount to protect user assets and ensure trust within the platform.
Value delivered
We used React for a dynamic and responsive frontend while leveraging IndexedDB for seamless blockchain data storage, enabling smooth transaction history management. For wallet security, we designed an encrypted vault utilizing PBKDF2 and AES-GCM algorithms, ensuring safe key management. The backend architecture was built using an event-driven model, with independent services communicating through event-based messaging, providing flexibility and scalability.
