Blockchain Bridges

Definition ∞ Blockchain bridges are protocols that permit the transfer of assets and information between distinct blockchain networks. These mechanisms facilitate interoperability, allowing tokens or data from one chain to be used on another, often otherwise incompatible, chain. They typically operate by locking assets on the source chain and issuing a wrapped or synthetic equivalent on the destination chain. This cross-chain capability expands the utility and liquidity of digital assets across the broader crypto ecosystem.
Context ∞ The security of blockchain bridges remains a primary concern, as they represent a common target for malicious actors due to the significant value often locked within them. Recent news frequently highlights security breaches or advancements in bridge technology aiming for greater decentralization and resilience. Monitoring developments in bridge security and the emergence of new cross-chain solutions is crucial for understanding the ongoing evolution of interconnected digital economies.
