Question

based on this text, the primary value of a smart contract is
a protecting both sides by using police.
b allowing customers to sue a company.
c building friendships among people.
d eliminating the need for middlemen.

Explanation:

Smart contracts are self - executing contracts with the terms of the agreement directly written into code. One of their key features is that they can operate without the need for intermediaries (like brokers, agents, etc.) to facilitate the transaction or enforce the contract. Option A is incorrect because smart contracts don't rely on police for protection. Option B is wrong as the primary value of a smart contract isn't about enabling lawsuits. Option C is also incorrect as smart contracts are about business/transactional efficiency, not building friendships. Option D accurately describes a primary value of smart contracts.

Answer:

D. eliminating the need for middlemen.
