   A financial institution is evaluating whether to integrate blockchain interoperability into its existing infrastructure. They currently operate a private blockchain for internal record-keeping and a separate public blockchain for customer-facing tokenized assets. The goal is to enable seamless movement of assets between these systems to improve settlement efficiency. What is the primary reason blockchain interoperability is essential in this scenario?

   • AIt enables the transfer of assets and data between the two blockchains without manual reconciliation or centralized intermediaries.
   • BIt ensures both blockchains use the same data format, simplifying compliance reporting.
   • CIt eliminates the need for a private blockchain, consolidating all operations onto the public chain.
   • DIt allows the two blockchains to share the same consensus mechanism, reducing operational overhead.

   A fintech firm operates a private Ethereum-based settlement network and a separate Hyperledger Fabric network for trade finance. They want to enable a corporate client to transfer a tokenized bond from the Fabric network to the Ethereum network without a centralized exchange. The teams note that Fabric uses endorsement policies and Ethereum uses Proof of Stake, and the data formats for asset metadata differ. Which approach directly addresses the consensus and data format differences while preserving the decentralized nature of the transfer?

   • AUse a relay chain with a light client on each network to verify the other chain's consensus and translate asset metadata into a common schema.
   • BRun a sidechain that pegs the Fabric asset to a separate Ethereum-compatible chain, ignoring the original Fabric consensus.
   • CDeploy a notary scheme where a trusted third party validates and signs the cross-chain transfer.
   • DManually export the asset data from Fabric and import it into Ethereum after a legal review.
