Understanding Smart Contracts

A smart contract is a program stored on a blockchain that automatically executes agreements when certain conditions are met. They are self-executing contracts with the terms of the agreement between buyer and seller written directly into lines of code.

How Does It Work?

Smart contracts operate on an "if-this-then-that" principle. When predefined conditions are met and verified, the smart contract automatically carries out the programmed action — without the need for intermediaries.

For example, in a smart contract for a home sale, if the buyer transfers funds to a specific address, ownership of the home is automatically transferred to the buyer. All of this happens on the blockchain, making it transparent and immutable.

Benefits and Applications

• Automation: Automates processes that would otherwise require manual intervention.
• Trust: Eliminates the need to trust third parties, as the code enforces the rules.
• Security: Once executed, transactions cannot be altered.
• Efficiency: Reduces the time and costs associated with traditional processes.

Smart contracts are the backbone of many Web3 applications, including DeFi, NFTs, and DAOs, enabling innovations that were previously impossible.
