Disassembly

Disassembly is the reverse engineering process of converting machine-readable bytecode back into a human-readable assembly format. This allows developers and auditors to inspect the actual logic that will be executed by the virtual machine, even if the original source code is unavailable or obscured.

In the context of DeFi, disassembly is a powerful tool for verifying that a deployed contract matches its published source code and for investigating potential backdoors or vulnerabilities in proprietary protocols. It provides transparency into the binary-level operations of financial derivatives, ensuring that the logic implemented on-chain is exactly what the developers claimed.

While reading assembly code is significantly more difficult than reading high-level languages, it is the only way to be absolutely certain of the protocol's behavior. This process is a fundamental defense against malicious actors who might deploy deceptive contracts.

It is an essential skill for security researchers operating in the trustless environment of blockchain finance.
