CoinWorld News, Cryptonews reports that cross-chain bridges are infrastructure connecting different blockchains, allowing assets and information to move between blockchains that cannot directly communicate. However, cross-chain bridges have also become prime targets for hackers, causing billions of dollars in losses. Due to the isolation between blockchains, users need cross-chain bridges to transfer assets, but this also makes cross-chain bridges concentrated targets, and any small flaw can lead to huge losses. The security of cross-chain bridges depends on their trust model, and many bridges rely on small external validators, making them vulnerable to attacks. Understanding how cross-chain bridges work and their risks is crucial for users when transferring funds.
