Why Do We Need VRF Despite Its Complexity? A Call for Community Insights

[NyxAzrael]

I'm struggling to understand why VRF (Verifiable Random Function) is a hard requirement in this implementation. While I recognize its value for generating verifiable randomness, the current implementation feels:

1. Overly complex (steep learning curve, cryptographic expertise needed)
2. Error-prone (easy to misuse due to intricate key management/proof verification)
3. Low usability (lack of abstraction/high-code overhead for simple use cases)

Key Questions:

1. What specific attack vectors does VRF mitigate here that simpler PRNGs (with secure seeding) couldn’t address?
2. Are there plans to provide higher-level abstractions/wrappers to reduce implementation risks?
3. Have alternative approaches (e.g. commit-reveal schemes, BLS signatures) been evaluated for usability trade-offs?

Suggested Improvement:
Could we add clearer examples of common pitfalls and a "VRF Best Practices" guide to lower adoption friction?

This format invites constructive discussion while respectfully challenging design decisions. It focuses on security trade-offs (not just personal preference) and proposes actionable next steps.

@PatrickAlphaC your insight is greatly needed sir.

Great questions:

1. What specific attack vectors does VRF mitigate here that simpler PRNGs (with secure seeding) couldn’t address?

Not true randomness. Remember, the blockchain is a deterministic system, so we should not rely on the blockchain for random numbers. We have seen many hacks where PRNGs are used, and they get exploited!

Now, if we didn't care if our application had predictable random numbers, then, sure we could use PRNG.

2. Are there plans to provide higher-level abstractions/wrappers to reduce implementation risks?

As of today, it's important to understand the implementation details so you can do it safe. The blockchain space is quite delicate!

3. Have alternative approaches (e.g. commit-reveal schemes, BLS signatures) been evaluated for usability trade-offs?

Yes, and some of these schemes can work depending on the project goals. But if you want the most generic approach that solves most needs for a random number, Chainlink VRF is the most straightforward.

Could we add clearer examples of common pitfalls and a "VRF Best Practices" guide to lower adoption friction?

Good shout!
