What is a smart contract?

The term smart contract was first coined by Nick Szabo in 1996, long before bitcoin appeared. By that, he meant electronic trading protocols between two parties, including a protocol for the execution of those obligations within the Internet. After a while, smart contracts began to gain popularity. The Ethereum blockchain alone recorded about 2M deals for 2020.




In a nutshell, smart contracts are digital contracts in the form of sophisticated computer code. They facilitate verification, control, and execution of all agreements. Moreover, they are stored inside a blockchain. If you use smart contracts to transfer cryptocurrency, in that case, no one is manipulating the funds.

Here’s a great example for you to understand the main principle of how smart contracts work.



Imagine a situation where you want to invest in a startup. The creators are unfamiliar (or anonymous) and can be reached only through the Internet. You are satisfied with their business goals and business plan (whitepaper), but you aren’t sure whether the product will be in demand. They need your investment – you need results. Both of you decide to make a smart contract, under the terms of which, as soon as 1 unit of product is sold, the startup will receive your investment for continued growth. Once that happens, the contract will do the exchange itself. So you don’t have to waste your time.

This example is a brief description of how exactly it works. However, it shows one of the main advantages of a smart contract – saving time. Also, smart contracts have many other useful features that can solve numerous problems.
