Cross-Chain Bridge

Definition ∞ A ‘Cross-Chain Bridge’ is a connection that allows digital assets or data to be transferred between two or more distinct blockchain networks. These bridges facilitate interoperability, enabling users to move assets from one blockchain ecosystem to another. They are essential for creating a more interconnected decentralized economy.
Context ∞ ‘Cross-Chain Bridges’ are frequently in the news due to security incidents and the potential for systemic risk they represent. Discussions revolve around the varying security models employed by different bridge designs and the inherent challenges in ensuring asset safety across disparate networks. Critical future developments to monitor include the adoption of more robust security audits and standardized bridge protocols.
