Bridge Validation Logic

Definition ∞ Bridge validation logic comprises the specific rules and processes that confirm the integrity and accuracy of cross-chain transactions within a blockchain bridge. This logic ensures that digital assets transferred between distinct blockchain networks are correctly accounted for and secured. It verifies that an equivalent amount of tokens is locked on the source chain and accurately represented on the destination chain.
Context ∞ The strength of bridge validation logic is a critical security consideration for decentralized finance, as weaknesses in this area have historically led to considerable asset losses through malicious exploits. News reports frequently identify failures in validation logic as the primary cause of bridge hacks. This underscores its paramount importance for maintaining secure cross-chain interoperability and safeguarding digital assets.
