Hi I'm an ethereum noob and I have a few questions about integrating ethereum into my app.
Imagine I want to create a transaction on the blockchain every time a user opens the MySecret app. I want to log this information. Eventually I will reward the users with "MySecret" tokens for letting me log this information. My questions are:
- Can I just use the standard Ethereum blockchain? Or do I need to create my own private chain?
- When I create this transaction, do I need special nodes to verify this transaction was indeed from a real device (and generated by a hacker)? Or does Ethereum handle this already? If I need special nodes to verify the transaction, won't I need several devices that have a lot of computing power?
