Thanks Arindam for explaining this so clearly, step by step. While today there are easier, more developer-friendly ways of getting data asynchronously, like the built-in fetch etc., it is always good to go to first principles and understand what is happening under the hood. Good job!

Thanks for this helpful introduction. Smart Contracts sound a lot like serverless functions - think Google Cloud or Netlify or Vercel - but I'm still struggling with the fact that running these latter-day lambdas requires payment?? By the way, the Rinkeby test eth faucet seems to have run out of funds already, testament to the popularity of your article I'm sure. It's an excellent tutorial. Thanks again.

Thanks for this Solidity primer. Coming from a Web2 background of several years, I try to find parallels and analogies to help me understand Web3. Smart Contracts to me sound a lot like cloud functions. What I am struggling to get my head around is the fact that running these latter-day lambdas requires payment ?? Thanks again.
