Cross-Chain Bridges

Definition ∞ Cross-chain bridges are protocols that allow the transfer of digital assets and data between different blockchain networks. These mechanisms facilitate interoperability, enabling assets on one blockchain to be utilized or exchanged on another. Without such bridges, blockchains would operate in isolated digital ecosystems, limiting the utility and reach of digital assets.
Context ∞ The development and security of cross-chain bridges are critical concerns within the blockchain industry, given their role in enabling a more connected digital asset ecosystem. News often focuses on new bridge launches, upgrades, or security incidents, underscoring their importance and associated risks. Debates frequently arise regarding the decentralization and trust assumptions inherent in different bridge designs.
