Bridge

A blockchain bridge is a tool that allows digital assets or data to move between two different blockchain networks. It works by locking assets on one chain and creating equivalent tokens on another. Bridges help resolve the problem of blockchain isolation, enabling more flexible and efficient use of decentralised applications. There are two main types: centralised bridges, which rely on third parties, and decentralised bridges, which use smart contracts. While they improve interoperability, they can introduce security risks.
