What are smart contracts?
Smart contracts are digital contracts that self-execute and self-enforce. This means that when the conditions of a smart contract are met, the contract automatically executes the agreed-upon terms. Smart contracts are tamper-proof, transparent, and incredibly efficient– eliminating the need for middlemen, paperwork, and costly delays.

How can smart contracts prevent fraud?
Because smart contracts are digital and self-executing, they can help to prevent fraud. For example, let’s say you’re buying a car from someone you met online. You might worry that the person could take your money and never send you the car. But if you use a smart contract, the transaction would be recorded on the blockchain. This would create a permanent record of the transaction, making it impossible for the person to take your money without also sending you the car.
