Why is ZK so difficult? Understanding the "torturous" computational complexity of zk-SNARKs in one article.

zk-SNARKs (ZKP) sounds like magic:
allows you to prove "I know" without revealing "how I know".

But it has a fatal weakness -
It's too hard to calculate.

🧵Let me elaborate:

1️⃣ What is ZK? Let’s explain it using eating ramen:

You said to the boss: "I ate 100 bowls of ramen yesterday, please let me into the foodie's leaderboard!"

Boss: Bring evidence!

You said, "I won't provide location, I won't share video, but I can make you 100% believe."

This is the essence of zk-SNARKs:
Do not expose the process, only verify the result.

2️⃣ How difficult is it to calculate ZK?

Using zk-SNARKs means:
• Build behavior into circuits/functions
•Construct mathematical proofs
•Let others verify without errors in a few seconds.

It's like:

🔧You wrote 50,000 lines of formulas in Excel.
📦Compressed to 2KB again
✅Others finish verification with a calculator in a few seconds.

For ordinary computers? It's simply hellish difficulty.

3️⃣ Is ZK really worth it?

Of course it's worth it! More and more scenarios are involving it:
Scene
Why is ZK needed?
Rollup
Compress blockchain transaction costs
Identity Verification
Verification without exposing privacy
Vote
Anonymous + Verifiable
But the problem arises: using ZK is like participating in an Olympiad competition every time.

4️⃣ @cysic_xyz How did you do it?

While others are focusing on algorithm optimization, Cysic directly goes for hardware:

💡"ZK too hard to calculate? Then let's create a chip specifically to speed it up!"

Cysic's positioning is like:
•Others use CPU to do zk-SNARKs
•Cysic uses ZK dedicated GPU
•Others climb the hill with bicycles.
•It directly drives the F1 racing engine

5️⃣ ZK is beautiful, but to run it, hardware is needed.

ZK is the Photoshop of the Web3 world,
But without a graphics card, it won't run.

The emergence of Cysic marks the official entry of ZK into the "GPU era."

Everything for the sake of:

✅ ZK is faster
✅ Lower costs
✅ Truly feasible

The charm of ZK = Security + Privacy + Simplicity
But the question has always been "Can it run?".

Cysic is providing a real solution with hardware.
