Let me tell you a story: 'At 3 AM, developer A K's computer screen is still lit up 😫. He stares at a screen full of error codes, having failed for the 17th time to retrieve cross-chain data, with Ethereum transaction records and Polygon NFT metadata like two parallel lines that can never intersect in his DApp 😤. This is not an isolated case; in the world of Web3, 'data islands' are becoming a nightmare for all entrepreneurs 😖.'
Breakthroughs in the data maze 🧐
Imagine opening a food delivery app, only to find KFC's data hidden in Meituan, and McDonald's orders can only be viewed on Ele.me, while payment records are forever scattered across banking apps 😵. This absurd scene reflects the current data situation in Web3: each public chain is an independent castle, with walls made of different underlying protocols and gates that have incompatible interface standards 🚪.
