## What exactly is Wormhole (W Coin)?
In simple terms: W coin is the token of the Wormhole protocol, and its core function is **to enable communication between different blockchains**.
Imagine that there are now hundreds of different blockchains each playing by their own rules, making data interoperability difficult. Wormhole acts like a "cross-chain bridge", allowing developers to easily build multi-chain applications, and users can seamlessly flow between different ecosystems.
**Key Points**:
- Wormhole itself **is not a blockchain**, but a communication protocol between blockchains.
- Has been integrated by hundreds of projects and applications
- Help projects expand user scale and enhance cross-chain activities.
In simple terms, it is to solve the "communication problem" of the multi-chain era, making the Web3 ecosystem more interconnected.
