Five Myths about Formally Verifying Smart Contracts

6/ Learn more about these five common misconceptions and why formal verification is trusted by all of the top protocols and companies in crypto:

medium.com

For a long time it puzzled me how something so expensive, so leading edge, could be so useless, and then it occurred to me that a computer…

5/ Myth: FV-approved code is bulletproof Fact: It can still have logic mistakes if the specification was inadequately written or missed important code properties.

@NotionalFinance

had a bug that FV proved impossible due to inadequate specification

Post-Mortem Analysis of the Notional Finance Vulnerability — A Tautological Invariant

4/ Myth: Blockchain systems are too complex for FV, which must model exact machine semantics Fact: Blockchains have a simple, abstract interface with well-defined semantics. You don’t need to worry about complex details like network communication or cryptographic primitives.

3/ Myth: Formal verification is tough because of computational cost. Fact: The real challenge is defining the required properties (specification). We verified 12 interesting smart contract in

@AaveAave

V3 with 3770 lines of Solidity code

2/ Myth: FV is only useful AFTER the code is mature. Fact: Do it early in the development process, when it's easier to fix bugs. Plus, integrating FV into CI can prevent mistakes from being introduced with code changes.

1/ Myth: Formal Verification (FV) only confirms the absence of bugs. Fact: Its main value is discovering specific bugs and preventing them before they can be exploited.

@MakerDAO

found a mistake the fundamental equation of DAI using FV

I’m quite sure formal verification is the next step in web3 audit contests. An audit only verifies a snapshot of the code, while a set of properly written rules can be verified upon each change in the code. I've been playing with

’s prover and it really blew my mind!
