I've tried to read the code 3-4 times now. Every time I have to give up. The "chain" thing is really bad code, even admitted by the author.

If you're considering GunJS, take a look at the code and verify it's something you'd want to debug, before going all-in.

I did go all in and it worked fine, great even. The devs are responsive on their Gitter for sorting things out and it was generally simple enough that I wouldn't need to mess with the internals

I saw the author present once, I couldn't follow anything they were talking about or the code samples presented.
