Question 14: What is the role of atomic swaps in cross-chain interoperability?

A. They merge multiple blockchains into a single network B. They enable direct peer-to-peer exchanges between two different blockchains without intermediaries C. They enforce a universal token standard across all chains D. They require third-party validators to approve transactions

Question 15: How do relayers contribute to cross-chain communication?

A. By validating transactions on behalf of a single blockchain B. By acting as centralized control points in blockchain networks C. By facilitating message passing and state verification between chains D. By preventing smart contracts from executing on multiple chains
