Blockchains are a popular topic, hot both for developers and for businesses trying to integrate or adapt the technology to their specific needs. At the same time, this technology is fairly new and there are limited options for developers to learn from and get in touch with the blockchain is and how to work with it. While reading the source is an option since most of the currently popular implementations are open source (and still required to get to the low-level details), there are, in fact, documents which can help you learn. This article is a collection of links to tutorials, blogs, technical documentation and tips & tricks for working with the currently most popular aspects of blockchains and products built on top of blockchain.
Cryptography is at the base of blockchain design and much of everything else will not make sense until you are familiar with it. See these resources to start learning how to use it:
I hope that these resources will help you get into blockchain development and will motivate you to explore and learn more about these fascinating and rapidly changing topics. On the other hand, it is very likely that some of these resources will be outdated eventually, and you should keep an eye on researching new ones.
