What Are Smart Contracts and How Do They Work?
Smart contracts are digital programs stored on blockchain networks that automatically execute when predetermined conditions are met. This straightforward yet powerful concept is revolutionizing various industries.
First proposed in the 1990s by cryptographer Nick Szabo, smart contracts were described as "a set of promises, specified in digital form, including protocols within which the parties perform on these promises." The launch of Ethereum brought this concept to life, enabling secure, transparent, and efficient digital agreements.
Think of a smart contract like a vending machine. When you insert a dollar, you get a Coke. The machine follows built-in rules, similar to if-then statements in code. When one party fulfills their obligation (inserting a dollar), the resulting action (dispensing a Coke) is triggered.
This automation ensures that agreements are executed precisely without the need for third parties. Unlike traditional contracts that require oversight for enforcement and dispute resolution, smart contracts eliminate intermediaries by automatically enforcing terms once conditions are met.
Smart contracts offer several key advantages:
- Elimination of middlemen: Reducing costs by removing brokers or lawyers
