Any ZKP developers here?

I’m seriously considering moving into Zero-Knowledge Proof development and would like to understand the real path to becoming one — beyond tutorials and surface-level guides.

I’m particularly interested in:

  • The actual learning curve and prerequisite knowledge

  • Real-world development experience

  • Challenges or bottlenecks you faced while transitioning into ZK

  • Skills that mattered in production, not just in demos

  • Common mistakes beginners make when entering the ZK space

My intuition is that ZK will become foundational, especially as privacy increasingly becomes a core requirement across blockchain protocols.

For circuit development, I’m currently leaning toward Noir, but I’d appreciate insights from anyone working with Noir, Circom, Halo2, or other proving systems in real environments.

Would really value honest perspectives from builders — what the journey actually looks like, not just the highlight reel. And what are the steps need to take and avoid to pursue it!

    If you want the honest version: ZK is a mindset shift. The first wall I hit wasn’t math — it was realizing every little thing turns into constraints and you can’t “just if/else” your way out.

    What mattered in real work for me was boring stuff: tight range checks, not accidentally under-constraining something, and learning to debug witnesses without losing your mind. Also… performance. A circuit that feels fine in a demo can become unusable the moment inputs look real.

    Noir is a nice on-ramp (fast iteration), but I’d still force yourself to understand what the compiler is doing, otherwise you’ll get stuck when something is “proving” but not actually proving what you think.

    @Merrythetechie Thanks for sharing your valuable insight.

    Also wanted to know how much of that under the hood math we need to master to move forward as a ZKP developer or the language bypasses it, and we will be good with understaning the the working of what the compiler and vice versa works etc!

    Sorry for the trouble, got pumped by the whole idea of ZKPs!
