I am in a group of “blockchain enthusiasts” and we started to talk about “levels” regarding knowledge of blockchain matters, so obviously I started to think about what those “levels” are. One approach is to depict the landscape in as much detail as possible and sort it there.
Here is a Mind Map for the ones that process information visually (there are other preferences). I used FreeMind (this is not an endorsement) and produced something to share. I took advantage of the MindMap interactivity and added all sorts of links and notes, but unfortunately it only works on the mapping software. So in lieu of that here is a PNG (poor substitute for the real thing).
Basically, I divided the knowledge landscape as follows:
I am personally stuck on L1, doing my best to have some not-so-crazy ideas on what the blockchain can do (and graduate to L2). Note I did not include the practical stuff, such as technical implementations (the systems administrator work). I am currently undergoing training on Hyperledger and also Ethereum Smart Contracts (good luck to me!).
I also need to update this thing as time changes everything (hopefully not a lot). I will not update the Ecosystem as that is by now a hopeless task, and someone is doing a better job than I could ever do anyhow.
