A DeFi protocol is considering integrating a privacy layer to hide transaction amounts, but regulators have warned that this could violate anti-money laundering (AML) regulations. The protocol wants to maintain user privacy while satisfying regulators. Which approach is most likely to be acceptable?

Using a mixer to obfuscate transaction origins

Implementing zero-knowledge proofs that allow regulators to verify compliance without seeing transaction details

Storing transaction data off-chain and only keeping hashes on-chain

Using a permissioned blockchain with a central authority to monitor transactions

A blockchain startup is choosing between a Proof of Stake (PoS) and a Practical Byzantine Fault Tolerance (PBFT) consensus mechanism for a public network. They want to allow anyone to participate as a validator. Which mechanism is more appropriate?

PoS, because it allows open participation based on stake.

PBFT, because it is more efficient.

Neither is suitable for a public network.

A central bank is evaluating the use of quantum-resistant cryptography for its future central bank digital currency (CBDC). What is the primary reason for this consideration?

To reduce energy consumption of the network

To enable faster transaction processing

To enable cross-border interoperability

To protect against potential future quantum computer attacks on current cryptographic algorithms

A bank wants to tokenize a portfolio of bonds and allow institutional investors to trade them on a blockchain. They need to ensure that only authorized parties can view transaction details. Which approach should they take?

Use a private database with a public blockchain for audit trails.

Use a public blockchain with zero-knowledge proofs.

Use a permissioned blockchain with role-based access controls.
