    Which audit signal indicates poor threat modeling?

    Explanation:
    A happy-path-only focus is a strong smart contract audit warning because it shows the developer tested normal user behavior but ignored attacker behavior, edge cases, abuse paths, oracle manipulation, permission mistakes, and failure modes. For blockchain security careers, this is also a hiring signal: strong candidates can explain what can go wrong, not only what should work. For deeper smart contract audit readiness signals for blockchain security hiring, connect this concept with AOB’s Smart Contract Security Audits Hub. If your hiring team is unsure how to screen for threat modeling in a Solidity, DeFi, or smart contract security role, AOB’s JD Review can help convert vague requirements into clearer proof-based screening signals.

    What’s the strongest proof for blockchain developers in hiring?

    Tip: Click "Play" to reveal options and start playing.

    #A

    #D
    Explanation:
    Verified GitHub commits, deployed smart contracts, test coverage, audit notes, debugging trails, and role-aligned project explanations create stronger hiring proof than a polished CV alone. In proof-based Web3 hiring, recruiters and founders are not only checking whether a blockchain developer knows Solidity, Rust, EVM, or DeFi concepts. They are checking whether the candidate can show readable evidence of how they think, build, test, and fix real problems. If your GitHub, CV, or portfolio does not clearly show proof-based Web3 hiring signals for blockchain developer roles, use AOB’s Web3 Hiring Signals hub to understand what recruiters actually verify. If the gap is already visible in your applications, AOB’s Web3 CV Review can help you turn scattered blockchain experience into clearer hiring proof.
