What is the purpose of zero-knowledge proofs in enterprise blockchains?

To replace the need for consensus mechanisms.

To increase the speed of transaction processing.

To encrypt all data on the blockchain permanently.

To prove the validity of a transaction without revealing the underlying data.

A legal firm is advising a client on automating a complex multi-party agreement with smart contracts. The agreement involves conditional payments based on external events. They are concerned about the legal enforceability and the 'oracle problem' (trusting external data). What is the best approach?

Avoid smart contracts and use traditional legal contracts.

Write the smart contract to self-execute without external data.

Use a public blockchain with a decentralized oracle network.

Use a permissioned blockchain with a trusted oracle service and include legal review of the smart contract.

Which characteristic is commonly associated with enterprise blockchains to meet business requirements?

Anonymity for all participants.

Scalability to handle a high volume of transactions.

Lack of regulatory compliance features.

High latency to ensure maximum security.

A logistics company runs a permissioned blockchain that processes 2,000 transactions per second, but their legacy ERP system can only handle 500 transactions per second. They want to maintain a consistent record on-chain without overwhelming the ERP. Which approach should they take?

Deploy the blockchain on a public cloud

Switch to a faster consensus mechanism

Implement off-chain processing with periodic batched settlement

Increase the block size to accommodate more transactions
