Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

A look into formal verification of smart contracts using Certora
Certora's tutorial on github is also a great starting point for the basic concepts, though the lessons for more advanced ones are still under development. The documentation provides a good overview and reference for many concepts, though it's also a work in progress, and redirects to an older set of docs for the more advanced ones. A multi-contract example repo is a good complement to see the documented concepts in action.

Blockchain transactions decoding: making wallet activity understandable
Lets look the events of Open Zeppelin’s ERC20 token contract:

Are ERC-777 Unsafe?
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.
- OpenZeppelin is trying to avoid paying a bounty for a vulnerability that caused $1,1B worth of assets freeze
- Security improvements of the ERC20 token standard
- Ethereums most used token standard ERC20 requires security enhancements
- The most used Ethereums token standard (ERC20) requires a security patch.

Best Solidity Vertion
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).
