Smart contracts are self-executing contracts with the terms of the agreement directly written into lines of code. They run on blockchain networks, such as Ethereum, and are designed to automatically enforce and execute the terms of an agreement between parties without the need for intermediaries.
Key Features of Smart Contracts
- Immutability: Once deployed, smart contracts cannot be altered or deleted.
- Transparency: The code is visible to all participants on the blockchain.
- Autonomous Execution: Contracts execute automatically when predetermined conditions are met.
- Security: They are secured by the blockchain's cryptographic principles.
Types of Smart Contracts
- Simple Smart Contracts: These contracts execute when a specific condition is met.
- Complex Smart Contracts: They can contain multiple conditions and actions.
How Smart Contracts Work
- Define the Contract: The parties involved agree on the terms and conditions.
- Deploy the Contract: The contract is written in a blockchain-compatible programming language (e.g., Solidity for Ethereum) and deployed on the blockchain.
- Execution: When the conditions are met, the contract automatically executes.
- Verification: The transaction is verified by the network and added to the blockchain.
Use Cases
- Real Estate: Automating property transactions.
- Legal Agreements: Simplifying legal document execution.
- Gaming: Creating in-game economies and token-based rewards.

Smart Contracts vs. Traditional Contracts
- Smart Contracts: Automated, transparent, immutable.
- Traditional Contracts: Requires intermediaries, more time-consuming, less transparent.
