Currently in the crypto ecosystem, different public chains operate independently, and cross-chain transfers have become an unavoidable requirement. However, traditional cross-chain bridging solutions face many issues—most rely on a fixed set of validators or consortiums for attestation, which introduces single points of failure and centralization risks.

Walrus Protocol offers a completely different solution to this problem. It uses zero-knowledge proof technology to build a cross-chain communication layer. The core logic is: users generate a cryptographic proof (called a "witness") on the source chain that confirms assets are locked, and then verify this proof on the target chain to unlock the corresponding assets. The clever part is that the original assets always remain under secure custody on the source chain, while users on the target chain receive fully autonomous wrapped assets. This approach avoids asset risk and significantly reduces transaction costs through batch processing.

Its more flexible modular architecture allows adaptation based on different blockchain consensus mechanisms and virtual machine features, laying a solid foundation for future multi-chain interoperability. The protocol's built-in governance token is used to pay validation fees, incentivize node operation, and facilitate on-chain voting. As the ecosystem expands, these technological advantages are expected to gradually translate into actual network effects and widespread application.
