How does Smart Contracts work?

Smart contracts are usually basic programs that are stored on a blockchain that run

when pre-established conditions are met. An understanding between buyer and 

seller is simply composed of a line of code, the code, and the arrangements 

contained that exist around a circulated decentralized

blockchain network. In simple and clear words smart contracts are set of instructions or a 

a program that runs when certain conditions are met that are defined by a

developer. On the blockchain, smart contracts are made and their transactions 

are completely traceable and are irreversible. which means once it's done

you can’t make any changes to it after it’s created.
