A consortium of five banks wants to share a shared ledger for interbank reconciliation. They need to control which banks can read which transaction details, and they must comply with regional financial regulations that require audit trails. They are considering a public blockchain like Ethereum. What is the most appropriate recommendation?

Use a public blockchain and encrypt all transaction data on-chain.

Use a public blockchain with a smart contract that restricts access to authorized banks.

Use a private database with a public blockchain for timestamping.

Use a permissioned enterprise blockchain with private channels and audit logging.

A shipping consortium is adopting a permissioned blockchain for trade documents. They are concerned about the lack of a common data standard across members and the effort required to integrate with each member's legacy systems. Which mitigation strategy should they adopt?

Use a single smart contract for all document types

Limit the blockchain to a few members with similar systems

Adopt an industry-standard data model and use middleware for integration

Require all members to replace their legacy systems with the blockchain platform

A global supply chain blockchain is experiencing performance bottlenecks due to high transaction volume and cross-border latency. They need to improve throughput while maintaining a single source of truth. They are considering sharding and off-chain processing. What is the most balanced approach?

Increase the number of nodes to improve throughput.

Implement sharding with careful design for cross-shard transactions.

Use a faster consensus algorithm like Raft without sharding.

Move all transactions off-chain to a centralized database.

A manufacturing company wants to integrate its permissioned blockchain with an existing ERP system. They need real-time data synchronization, but the ERP is legacy and does not support modern APIs. They also need to ensure data consistency between the two systems. What should they do?

Replace the legacy ERP with a modern system that supports APIs

Use a nightly batch job to synchronize data

Use a middleware integration layer that connects to the ERP's database and the blockchain

Use smart contracts to directly access the ERP database
