Hi
I am a developer working on a Blockchain app development. I want to add Blockchain features to the app, but I am not sure where to start. Can anyone provide some guidance?
Thank You
Yeah, jumping into blockchain can feel overwhelming at first. Starting with clear goals for what features you want helps a lot. Playing around with testnets and simple smart contracts can make it less intimidating. I found some surprisingly useful insights on https://planet-positive.org/—they sometimes share beginner-friendly tech updates that made tricky concepts click for me. Breaking it down into small steps and experimenting is key.
If you’re just starting with blockchain in your app, first decide what you want it to do. Common uses include securely recording transactions, automating tasks with smart contracts, handling tokens/NFTs, decentralized identity, or supply chain tracking.
Next, pick a blockchain platform:
- Ethereum (or Layer 2s like Arbitrum/Optimism) for robust smart contracts.
- Polygon (PoS or zkEVM) for low-cost Ethereum-compatible apps.
- Solana for fast/cheap transactions (but less reliability).
- Hyperledger Fabric for private business apps.
To build:
- Write smart contracts (automated agreements) using Hardhat or Foundry.
- Connect your app with libraries like ethers.js.
- Let users log in with wallets (MetaMask or WalletConnect).
Test safely on testnets (like Ethereum’s Sepolia or Polygon’s Amoy—avoid Goerli/Mumbai, as they’re outdated). Always audit your code and never expose private keys (use .env files).
Helpful tools:
- Alchemy/QuickNode (blockchain connections).
- IPFS/Filecoin (decentralized storage).
- ThirdWeb (simplified development).
Start small, test often, and build step by step!
