Bridge
A protocol that enables transferring assets or data between different blockchains.
In-Depth Explanation
Bridges lock assets on one chain and mint/release equivalents on another. They're essential for cross-chain liquidity but are high-value attack targets—billions have been lost to bridge exploits. Bridge security models vary from trusted (multisig) to trust-minimized (light clients, ZK proofs).
