What exactly is the EVM, and what does “EVM-compatible” mean? Don’t panic—your class rep is here:
Every EVM opcode has a fixed Gas cost. Operations such as writing to storage cost much more than ordinary computation.
Once a contract is deployed, its bytecode is fixed and anyone can view it. Whether you can read the source code depends on whether the developer has published it on a block explorer.
You only learn after paying tuition: read the manual first.
