Polygon 101: Foundations and Structures

Programme for Teaching NEAR Protocol

Introduction to Tezos: Foundations, Protocols, and Network

7. Solidity by example

For those with some previous experience in software engineering, a more basic method of learning to be a web3 developer is Solidity by example.

All the basic knowledge you need to start coding is available on this website and YouTube channel!

8. ProtoSchool

ProtoSchool is an online teaching community that teaches decentralized web protocols and tools. You will learn about decentralized web ideas, protocols, and tools through the interactive, self-guided lessons.

9. LearnWeb3DAO

A comprehensive, top-notch learning tool for Web3 developers is LearnWeb3. As you finish each track, you'll earn NFT, develop Web3 abilities, and meet friends in the community.

There are four learning paths available for the Progressive level:

Newbie: Get familiar with the fundamentals of Web3.

Go deep and create decentralized apps (dApps) as a sophomore.

Junior: Integrate yourself with the ecology.

Senior: Study hacking and Web3 security.

Tutorials on the blockchain networks of Flow and Celo are included in the Growth level.

10. The Cyfrin Updraft web3 development courses cover a wide range of topics, from "What is a blockchain" to "Solidity Basics" to "Advanced Deployment and Assembly" to more complex subjects like "smart contract security and auditing" and "fuzzing."

This course is taught by some of the best web3 professionals, making it a data dump from a passion project that covers all the groundwork needed to get started with web 3. You will learn more than the typical developer and be able to create some incredible protocols.

More than fifty hours of free smart contract development and security training are available on Cyfrin Updraft:
