The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
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
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.

A look into formal verification of smart contracts using Certora
Understanding a smart contract as a finite-state machine (obligatory mention to Yoichi's bamboo, my favorite smart contract programming language that never happened) allows us to define clear rules on:
