When it comes to learn new technology, it is highly recommended to think about roadmap and resources. As blockchain is a very fresh and latest technology, many newbies can be easily lost. That’s the reason to create a list.

Agenda:

• blockchain theory,
• Cryptography,
• Dapp development,
• Whitepapers,
• Smart contracts,
• Podcasts.

Blockchain theory:

• Blockchain by IBM

https://developer.ibm.com/technologies/blockchain/

IBM provides a lot of high quality data and learning resources for new adepts of blockchain technology. It is highly recommended to start with their resource.

This videos are explaining visually how fundamentals of blockchain work. You can find there more about hash, signing, keys and chain structure.

• blockchain with JavaScript

It is a repo which I created while trying to understand blockchain technology. Using the very easy programming language in developing functional api teaches a lot. Check my code here (name of the coin is dedicated to my wife):

Cryptography:

• Ethereum book

https://github.com/ethereumbook/ethereumbook/blob/3812a5dfa5b851a1aaa52b14c5aea6c74629e5a0/keys-addresses.asciidoc
