Definition ∞ A canonical bridge is a specific type of cross-chain bridge that facilitates the movement of assets between two distinct blockchain networks. It ensures that an asset transferred from one chain to another retains its original value and identity. This mechanism typically involves locking the original asset on its native chain and minting a wrapped representation on the destination chain. Its purpose is to maintain a verifiable, one-to-one correspondence between the original and wrapped assets.
Context ∞ Canonical bridges are frequently mentioned in news concerning blockchain interoperability and the expansion of decentralized applications across multiple networks. A critical discussion point revolves around the security vulnerabilities associated with these bridges, as they represent a common target for exploits. Future advancements aim to enhance the cryptographic security and decentralization of these bridging solutions. Understanding their operation is crucial for assessing the integrity of cross-chain asset transfers.
