What Is Smart Contract And How Can Your Business Benefit From It?

By Maryna Cherednychenko

Today, the idea of “smart contracts” is a promising cloud technology for storing various papers. This post will clarify what smart contracts stand for, how they work, and why you need them.

What Are Smart Contracts?

With smart contracts, you can buy, sell, rent, trade without involving a go-between. If you want to get a clear understanding of the operating principle, think of the penny-in-the-slot machine. You would contact a notary or lawyer in a traditional model and then wait to receive a needed paper. In a smart version, you insert a crypto coin into a slot machine and get your film subscription or health insurance pop up.

There is no way to fool a smart contract. If one of the parties does not fulfill the obligations, it is subject to fines or other sanctions. The other side, in turn, receives full compensation.

How Do Smart Contracts Work?

If you translate the program code into spoken English, it will look something like this:

If client X receives item Aand if client X pays for item A,then send item B to this client.

Since the smart contract is self-running, you don’t need to involve third-party experts to verify and control it. Thus, you save time, money and eliminate the risk of fraud.

Note that smart contracts are reusable. Once you write a program, you can utilize it as many times as you like with other input data.

Logical Algorithm

In the first case, the buyer pays a fee for the transfer of money. If the buyer does not pick up the goods, the seller loses money for sending them back and forth.

In the second case, the buyer risks losing the deposit if the seller does not send the goods. It will also take time and costs to make a refund if the product does not meet expectations.

With a smart contract, cheating is impossible. If contract conditions are not met, each side gets back money and goods without commissions and overpayments.

Let’s see the behind the scene actions that take place in a program.

  • A clothing manufacturer and a client put value into an information repository. Once the value is placed, it cannot be quickly withdrawn.
  • The client puts money for goods.
  • The manufacturer places a tracking number.
  • The manufacturer receives payment confirmation, and the buyer gets a tracking number.
  • If the buyer picks up the package, the manufacturer receives the money.
  • If the buyer doesn’t like the product, they don’t pick it up and get money back.
  • If the buyer doesn’t come to the post, the seller gets the delivery cost there and back, and the buyer receives the rest of what they paid.
  • When both parties complete the contract terms, the contract gets automatically closed and remains in blockchain storage.
