Hello! My first question here :)
I am looking for some tutorial that helps me understand the basics of getting started with a new blockchain and its associated whitepaper.

More specifically,

I really like whats going on in the space, and have an idea of my own for a blockchain. I am aware there are ERC20 tokens - which should help me build on top of Ethereum. The concept i have in mind has a different way of dealing with transaction fee on the network rather than gas and involves microtransactions, making it impossible for me to run it on Ethereum (Which was my first choice). I am following developments on Lightning Network and Plasma for micropayments, but then Plasama isn't deployed yet.

I do not have experience building blockchains in the past, but i have been following the research going on in this space.

I really want to know what is a good place to start thinking about a new blockchain - As a ethereum fork , ERC20 or otherwise.

I have written a first draft of a whitepaper that explains my idea, and will be ready to show others very soon. What's the best way to get feedback on the paper? What are the things i need to keep in mind before getting such feedback?

Any help on these lines, deeply appreciated! :)
