Why Gas Matters:

• Prevents Abuse: By charging for computational resources, Ethereum discourages spam and abuse on the network.
• Incentivizes Efficiency: Developers are motivated to write optimized code to minimize gas costs.

Now that you’ve built a basic DApp, you can explore more complex and real-world use cases. DApps can be used in various domains, including:

• Decentralized Finance (DeFi): Building financial services like lending platforms, exchanges, and stablecoins.
• Gaming: Creating decentralized games where users truly own in-game assets.
• Supply Chain Management: Tracking and verifying the provenance of goods.
• Identity Management: Developing secure and decentralized identity systems.
