Bridge
Definition
A blockchain bridge is a protocol that allows assets and data to move between different blockchains — e.g. ETH from Ethereum to Polygon. Bridges typically lock tokens on the source chain and mint wrapped versions on the destination. Bridges are critical infrastructure for multi-chain DeFi, but have been the target of the largest hacks in crypto history (Ronin: $625M, Wormhole: $325M). Trust-minimized bridges using ZK proofs are emerging.
Why Does This Matter?
Understanding Bridge is essential for anyone investing in cryptocurrencies or working with blockchain technology. This concept directly influences how projects are valued, how markets behave, and what risks and opportunities exist for investors.
