Description

We need to see if Z3 provides better bitwise reasoning when using the BitVec representation. There is also the question of whether if it's feasible to switch to this, so we need to test performance first. The person investigating this should talk to someone working on KEVM to figure out how to test this.

Research direction

Start by talking with someone working on KEVM to learn how to test the BitVec representation. Benchmark the current representation against BitVec for bitwise reasoning, then document the performance results and whether switching is feasible.
