So I'm trying to build the most simple Daap to make a POC. I just want to register messages/strings on a block so that any given duplicate messages are ignored.
I've done a lot of research but I'm overwhelmed by the information there's available. The problem I'm having is to have a decent test net/private net to test my application.
I've tried Hyperledger Fabric but there are some broken issues and it requires a lot of stuff that I don't yet fully understand (like docker and vagrant for instance)
I made a lot of progress working with Go-Ethereum framework which I can use the Web3j API to send my requests. But for some reason, I'm having difficulty now connecting to a ROPSTEN network or even creating a private network to test(using $geth --testnet or $geth --rpc and every possible combination). It just won't start or it will take too long and then it connects to Ethereum Blockchain which is not what I want(for now).
So does anyone know some framework or even a simple way to create our private network without geth?
I just need to initialize a private-net that I can use with web3j, then everything will fall into place.
Thank you in advanced.
