Trustless Bridge

Definition ∞ A trustless bridge is a protocol that enables the transfer of assets or data between different blockchain networks without requiring users to rely on a centralized intermediary. These bridges operate through cryptographic proofs and smart contracts, ensuring the integrity and security of cross-chain operations. They minimize the need for third-party trust, enhancing decentralization. This mechanism facilitates interoperability across disparate blockchain ecosystems.
Context ∞ News frequently discusses trustless bridges as critical infrastructure for achieving true interoperability within the fragmented blockchain landscape. Security vulnerabilities in bridges have led to significant exploits, making their robust design and auditing a paramount concern. Ongoing developments aim to improve the security, efficiency, and decentralization of these vital cross-chain connections.
