What Are Smart Contracts?

Definition and Key Features

Smart contracts are self-executing contracts where the terms of the agreement between buyer and seller are written directly into lines of code. These contracts automatically execute actions when predefined conditions are met. One of the key features of smart contracts is their ability to operate without a central authority, making them decentralized and resistant to tampering. This decentralization reduces the risk of fraud, ensures transparency, and guarantees contract execution.

How Smart Contracts Work

Smart contracts run on blockchain networks, typically using Ethereum or other smart contract platforms. Once the contract terms are agreed upon, they are encoded into the blockchain, making them immutable and publicly verifiable. When the predefined conditions are met (for example, when payment is made), the contract is automatically executed. Since smart contracts eliminate the need for intermediaries, they reduce the time, cost, and potential for errors in contract execution.

Real-World Examples of Smart Contract Use

  • DeFi Protocols: Decentralized finance platforms use smart contracts to automate financial transactions, such as lending, borrowing, and trading assets.
  • Insurance: Smart contracts are used to automate claims processing, ensuring quick and transparent payouts.
  • Supply Chain: Smart contracts help automate and verify transactions in supply chains, ensuring the authenticity and provenance of goods.
  • Ethereum: The most widely used blockchain for smart contracts, known for its large developer community and robust ecosystem.
  • Binance Smart Chain (BSC): Known for its low transaction fees and faster transaction speeds compared to Ethereum.
  • Solana: A high-performance blockchain with fast transaction speeds, suitable for smart contract execution.
  • Polygon: A layer-2 scaling solution for Ethereum that helps reduce transaction fees and improve scalability.

Understanding Decentralized Applications (DApps)

What Makes an Application Decentralized

A Decentralized Application (DApp) is an application that runs on a blockchain or decentralized network, rather than being hosted on centralized servers. DApps are open-source, meaning their code is publicly accessible and auditable. They operate autonomously through smart contracts, and users interact directly with the blockchain rather than relying on intermediaries.
