Great post! I've been curious about Web3 and Solidity but haven't had the chance to dive in yet. Can you explain what drove you to build a decentralized web app and what challenges you faced?
build_erstwhile 6 months ago next
I was motivated by the idea of censorship resistance and the autonomy that decentralized apps can provide. The biggest challenge I faced was learning Solidity and understanding how to write secure and efficient smart contracts. I recommend checking out the Solidity documentation and online tutorials for beginners.

Interesting, I didn't realize that Web3 and Solidity could be used to build a full web app. How did you handle user authentication and storing data on the blockchain?
build_erstwhile 6 months ago next
To handle user authentication, I used Web3's built-in authentication system, which allows users to log in with their Ethereum wallets. For data storage, I used IPFS (InterPlanetary File System) which is a p2p filesystem that allows you to store data in a distributed and decentralized way. Instead of storing data directly on the blockchain, I store the IPFS hash on the blockchain which avoids the high gas costs and limitations of storing data directly on the blockchain.

I've heard of IPFS before but I'm not too familiar with it. Can you explain more about how it works?
build_erstwhile 6 months ago next
Sure! IPFS is a protocol that allows you to store data in a decentralized manner. Each file or directory is given a unique hash that can be used to access that data. When you want to retrieve the data, your IPFS client will look for peers who have the data and download it from them. This way, data can be accessed even if the original source is no longer available. IPFS also provides content addressing, which means that data can be accessed by its hash instead of its location, making it resistance to censorship.

I'm impressed with what you've built, but I'm concerned about the scalability of decentralized apps. How do you plan to handle increasing user base and data?
build_erstwhile 6 months ago next
Scalability is definitely a concern when building decentralized apps. I'm currently researching different solutions such as using state channels for off-chain transactions and implement a Layer 2 solutions such as Optimistic Rollups or ZK-Rollups for more complex computations. I also plan to use a decentralized storage solution such as Filecoin which is built on IPFS.

How did you ensure the security of your smart contracts? Did you use any security libraries or tools?
build_erstwhile 6 months ago next
I took several measures to ensure the security of my smart contracts. First, I used formal verification tools like Mythril and Oyente to check for common vulnerabilities. I also followed best practices such as using multiple contracts for different modular functionality, very less usage of low-level assembly code and enganging security auditors to review my contracts. Additionally, I used open-source libraries like OpenZeppelin to enhance security features.

Do you have any plans to add support for other blockchain platforms such as Binance Smart Chain, Polygon or Solana?
build_erstwhile 6 months ago next
Yes, I'm planning to add support for other blockchain platforms in the future. Each platform has its own unique features and scaling solutions, so I plan to carefully evaluate which one will be the most appropriate for my app. Additionally, by making the app platform-agnostic, I aim to make it more accessible to a wider audience.

I'm interested in learning more about Web3 and Solidity. Do you have any resources or recommendations for someone just starting out?
build_erstwhile 6 months ago next
I'm glad to hear that! Some great resources for learning Web3 and Solidity include the official Solidity documentation, CryptoZombies, and the Ethereum solidity community. These resources should provide you with a solid foundation to start building your own decentralized apps. Don't be afraid to make mistakes and deploy contracts to a local testnet while you learn. Good luck on your journey!
