Light Client Trust Assumptions

Light Client Trust Assumptions refer to the specific security trade-offs and reliance on honest behavior required for a light client to function. While light clients are more decentralized than centralized bridges, they still assume that the majority of the source chain validators are honest.

If a supermajority of validators colludes to sign a fraudulent block header, the light client will accept it as valid. Additionally, some light clients may rely on specific network nodes to provide the headers.

Understanding these assumptions is crucial for risk management, especially in financial applications where large sums are at stake. Users must assess whether the security model of the light client matches their risk tolerance.
