   A consortium of banks is reviewing a proof-of-concept for a trade finance platform that uses smart contracts to automate the release of funds upon delivery confirmation. The pilot showed a 40% reduction in processing time, but also revealed that a bug in the contract could lock funds permanently. What is the most important lesson from this case study?

   • ASmart contracts can improve efficiency, but they must include safeguards such as upgradeability or emergency pause mechanisms to mitigate code risks.
   • BSmart contracts are not suitable for trade finance because they cannot automate complex processes.
   • CThe consortium should abandon the platform because any bug makes the entire approach unusable.
   • DThe only benefit of smart contracts is cost reduction, and risks are negligible if the contract is audited once.

   A real estate tokenization platform wants to offer fractional ownership of a commercial building. They plan to use a smart contract to manage ownership and rental income distribution. However, they face a conflict: they want to allow secondary trading of tokens, but they also need to comply with securities regulations that restrict who can hold the tokens. Which design best resolves this conflict?

   • AAllow unrestricted trading on a decentralized exchange, and rely on the exchange to perform KYC checks.
   • BImplement a whitelist of approved addresses in the smart contract, and require that all transfers only occur between whitelisted addresses.
   • CProhibit all secondary trading to avoid regulatory issues, and only allow initial issuance.
   • DUse a proxy contract that can be upgraded to change compliance rules, but do not enforce any restrictions initially.
