Smart Contracts

Smart contracts are revolutionary digital agreements that operate on the blockchain, transforming how transactions and agreements are executed and enforced. Unlike traditional contracts that require manual oversight, verification, and enforcement by trusted intermediaries, smart contracts are self-executing pieces of code that automatically carry out the terms of an agreement once predefined conditions are met.

What Are Smart Contracts?

A smart contract is a computer program stored on a blockchain that facilitates, verifies, and enforces the negotiation or performance of a contract. These contracts are written in programming languages such as Solidity (for Ethereum) and are deployed onto blockchain platforms that support smart contract functionality. Once deployed, they function autonomously, executing specific actions when triggered by certain conditions.

How Do Smart Contracts Work?

Smart contracts operate based on a simple principle: if certain predefined conditions are fulfilled, then specific actions are automatically executed. For example:

• If a payment is received, then the ownership of a digital asset is transferred.
• If a shipment reaches a designated location, then release the escrow funds.
• If a certain date arrives, then a subscription is renewed.

These conditions and actions are coded into the smart contract, which resides on the blockchain. When the conditions are met—detected through on-chain data or external oracles—the contract automatically enforces its rules without the need for manual intervention.

Key Features of Smart Contracts

• Automation: Once deployed, they operate independently, eliminating delays caused by manual processing.
