The blog also has tutorials to get you started and teach Ethereum concepts.
Core blockchain dev, i.e. at a protocol level requires serious chops, not the kind of thing you can just pick up in a few months.
I'd recommend brushing up on broad blockchain concepts and not just intensely studying a single chain / platform. If you want to get into the industry your best bet is to find a company willing to hire you and let you learn hands on.
If you're interested in Ethereum Smart Contracts I wrote: http://ethereumdev.io/
Clearly written articles, thx! I’m n00b in Smart Contracts but they seem like interfaces to reading/writing to a data store. If I didn’t totally botch what they are. Then I don’t really get why they’re “smart”. The pitfalls of regular programming, seem to apply to contracts. Seems like I could easily code a bug in a smart contract and have it t deployed to the network?? Or did I miss something?
There's this course by the people who wrote `Bitcoin and Cryptocurrency Technologies` It covers the basics pretty well. http://bitcoinbook.cs.princeton.edu/
Earlier quoted context omitted.
Those are in line with my understanding too, but I'm asking what is there to learn about blockchain technology, not what the use cases are. (That's actually also a question I have, but a separate question to me.) To me a blockchain is just a tree, where the "parent pointers" are just hashes of the parent nodes rather than their addresses. And I guess to pick one as the "correct" one, you just choose the one with (say…
Based on my cursory understanding of the topic, The Merkle tree has been around for a while, but Satoshi figured out how to use that to achieve decentralization, and consensus building. If you ask me, that's quite revolutionary. Yes, the blockchain is just a gigantic DAG, but adding and deleting nodes on the graph is where the crux of the matter is I guess. I am starting to understand the logic from a currency perspe…
And proof of work is literally just the hash having a certain number of zero bits, right? Definitely a neat idea but hardly revolutionary if that's all there is to it.
Related, how does the blockchain structure look on paper? As in a data structure? What fields does it have? I have a project idea, but I want to build the data structure from scratch as opposed to cargo culting something on top of Ethereum.

I found this visual tutorial on blockchain helpful.
The book "Mastering Bitcoin" really helped me to understand the blockchain and bitcoin properly. It's available free online here~ http://chimera.labs.oreilly.com/books/1234000001802/index.ht... The author is putting out a similar book called "Mastering Ethereum" in February, also through O'Reilly.
I just read the preface and have to ask... is this heavy on marketing, cheerleading and kool-aid? First the author makes it sound like the Nakamoto paper was sent from the heavens and then this: > I became obsessed and enthralled, spending 12 or more hours each day glued to a screen, reading, writing, coding, and learning as much as I could. I emerged from this state of fugue, more than 20 pounds lighter from lack of…
