As we know, the technology involved in the blockchain has covered a significant number of aspects and is also in the midst of rapid growth and change. Smart contracts are very critical for anyone who want to grasp blockchain technology. I have never seen a person like PatrickAlphaC with great passion and energy doing such an excellent course.
The course introduces as below:
Welcome to the repository for the Ultimate Web3, Full Stack Solidity, and Smart Contract - Beginner to Expert Full Course | Javascript Edition FreeCodeCamp Course!
The course not only shows many outstanding kinds of stuff in video format but also includes many, many valuable references in Github, challenging everyone’s patience. It’s long and long, 32 hours.
From my understanding, grasping this technology is like running a marathon; the above course is a great help for everyone. And the below projects are involved in the demo projects in this course. I think that can help me and others deepen understanding from the ground and move to the more advanced usage.
The blew projects have been deployed in the IPFS(by the https://app.fleek.co/ )。
