# Guest Post — Beyond Post-Quantum Cryptography: Why Execution Integrity Is Central to Quantum-Safe Web3

**[The Quantum Insider](https://daily.dev/sources/thequantuminsider)** · 4 min read · 0 upvotes · 0 comments

## Summary

Post-quantum cryptography addresses mathematical vulnerabilities but misses the primary attack vector in Web3: execution-layer compromises. Most digital asset losses occur when malware manipulates transaction intent, keys, or wallet state before signing, not from broken cryptography. Deterministic execution integrity at the OS level prevents unauthorized code from accessing sensitive processes or data, addressing the real-world threat surface that quantum-resistant algorithms alone cannot protect against.
