full-blockchain-solidity-course-py VS openzeppelin-contracts

I really liked this course for learning everything. https://www.youtube.com/watch?v=M576WGiDBdQ There are 13 lessons in it if u look at the description. So each lesson is an hour and a half about That gets you solidity + front end experience though https://github.com/smartcontractkit/full-blockchain-solidity-course-py Follows along with the video

I personally like brownie because I actually like Py and the best course I found online was using it. If you decide to go with Brownie I recommend it, Patrick is an awesome dude and the course is high level: https://github.com/smartcontractkit/full-blockchain-solidity-course-py

A lot of information is packed into this course, so don't do it all in one go! Remember to take breaks, and jump into the GitHub discussions and ask questions, or on Stack Overflow! This is easily one of, if not the most dense blockchain tutorial on the planet.

I have decades of experience as a programmer (.Net, php, JS, React) , but I have only completed Cryptozombies and I am halfway through FreeCodeCamp.org 's Full Blockchain Solidity Course lessons (featuring Ethereum, Solidity, Python, brownie - which is excellent btw).

I started with Cryptozombies, and now I am coding along with Free Code Camp's Solidity Blockchain Smart Contracts course.

Lets look the events of Open Zeppelin’s ERC20 token contract:

ERC-777 is difficult to implement properly, due to its susceptibility to different forms of attack(opens in a new tab). It is recommended to use ERC-20 instead. This page remains as a historical archive.

This depends if you're writing a contract from scratch or using existing code. If you're making something new, then yes (recommend not to use THE most recent available, always better to go with tried and tested). For existing projects, never try to override the solidity version. This may be a pain with "@" imports - ideally everyone should specify the library version (e.g. https://github.com/OpenZeppelin/openzeppelin-contracts/blob/v2.5.1/contracts/token/ERC20/ERC20.sol).
