Message Passing Security

Definition ∞ Message passing security refers to the mechanisms and protocols that protect the integrity and confidentiality of information exchanged between different components or layers of a blockchain system. It ensures that data transfers, especially across distinct networks or modules, remain uncompromised and accurately delivered. Robust security in message passing is vital for the reliable operation of decentralized applications and cross-chain communication.
Context ∞ As blockchain ecosystems evolve towards modular and interconnected architectures, the security of message passing becomes a paramount concern. Recent news frequently highlights vulnerabilities or advancements in cross-chain communication protocols, underscoring the continuous efforts to fortify the secure exchange of data between disparate digital asset systems.
