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
There can be find an explanation of basic cryptography in ethereum. Very valuable content, worth of bookmarking.
- My own 100 days of web3 challenge

As a fan of math and cryptography, tried to explain in easy words, how asymmetric cryptography works and how is connected with blockchain. Hope it is worth of reading.
Dapp development:
- Dapp University

Smart contracts:
- Solidity docs
https://docs.soliditylang.org/en/v0.4.24/solidity-by-example.html
It is something developers hate doing, reading docs. Unfortunately it is obligatory to have a good start. Just jump into it and try to understand, docs exist to help, not to harm coders.
- Open zeppelin
https://github.com/OpenZeppelin/openzeppelin-contracts
Open zeppelin is a very valuable and tested repo with ready functions for smart contracts. Try to understand the very basic code and use it in development.
