A look into formal verification of smart contracts using Certora
The main challenge is dealing with non-view functions. The default behavior of the prover is to assume that an external call can alter all state on every contract but the caller, noted as HAVOC_ECF. This can lead to state changes in external contracts that are unreachable, making verification more difficult. Furthermore, it assumes that the call is non-reentrant, which in reality is a frequent source of attacks. This last issue can be avoided by indicating that calls can re-enter, noted as HAVOC_ALL, but this means that an external call can mutate any state in any contract, caller included. This leaves the contract being verified in a state where we don't know anything about it after an external call is made. This severely limits what we can prove.

Daily General Discussion - October 4, 2022
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

Truffle VS Hardhat VS Brownie
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

Top 10 Smart Contract & Solidity Developer Learning Resources
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.
