Ask HN: Blockchain Development Resources

Hi,

I want to get deeper understanding and more involvement in blockchain development area. Please note that I'm not talking about on-blockchain development (smart contracts, etc...), but about development of the underlying blockchain technology.

If I would want to build a new blockchain (just hypothetically - I know I should use existing ones) what would be the best

- discussion boards on that topic?

- bloggers to follow?

- three blockchain projects to look at from the architecture and code quality point of views?

- resources for starting out? (I'm an experienced developer, so not "for Dummies" series. I need enough theory to build solid foundation, but I don't plan to do PhD :-))

Thanks a bunch!
