Why might using a Proxy contract be beneficial in smart contract development?

a: To increase the gas limit for transactions. Explanation

Explanation

b: To delegate control and enable upgradeability. Explanation

Explanation

c: To encrypt sensitive data in the blockchain. Explanation

Explanation

d: To reduce the overall complexity of the contract code. Explanation

Explanation

What is the key difference between a traditional smart contract and a Proxy contract?

a: Traditional smart contracts can be upgraded without redeployment. Explanation

Explanation

b: Proxy contracts combine interface and implementation in one contract. Explanation

Explanation

c: Proxy contracts separate interface from implementation, allowing upgrades. Explanation

Explanation

d: Traditional contracts store data off-chain while Proxy contracts do not. Explanation
