Definition ∞ Trustless bridges are protocols that enable the transfer of digital assets between different blockchain networks without requiring a trusted intermediary. They achieve this through cryptographic proofs and smart contract logic, ensuring that asset transfers are verifiable and secure. The absence of a central authority mitigates counterparty risk. Users can move assets across chains with confidence in the protocol’s integrity.
Context ∞ Trustless bridges are fundamental infrastructure for the interoperability of blockchain ecosystems. News coverage often highlights the launch of new bridges connecting disparate networks, or the security vulnerabilities that have affected existing ones. The development of more robust and secure bridging solutions is critical for the expansion of decentralized finance and the seamless movement of assets across the blockchain landscape. Their reliability directly impacts the composability of decentralized applications.
