I just heard about Solana but I don’t have experience with blockchain tech at all. Can someone send me to the right place to learn what can I do with it and also a codebase I can try? I tried this one https://github.com/solana-labs/example-helloworld but I get
Failed to connect to localhost port 8899: Connection refused when I run
npm run localnet:up.
I apologize if there is a better place to ask this question!
