📌 Technical principles｜Ethereum Virtual Machine (EVM)
· What it is: Each EVM opcode has an associated gas cost. Operations like writing to storage are far more expensive than ordinary computations.
· Why it matters: “EVM-compatible” means developers can write a contract once and deploy it across multiple chains. It also means similar contract vulnerabilities may exist on several chains at the same time.
· Caution: Before interacting with a contract, check on a block explorer whether its source code has been verified. Be extra careful with contracts whose source code isn’t public.
