Lot of people joined the zk train without knowing what it truly entails
most did it for hype, not the tech

i read through the zk handbook so you don’t have to
here’s a full breakdown of what zk really is, what problems it solves, and who’s building with it
🧵👇

Let’s start with what ZK is ?

Zero-knowledge proofs (ZKPs) let you prove something is true without revealing the underlying data.

Instead of sharing the actual info, you just show a proof that your data satisfies certain rules.
This has huge potential for improving privacy, scalability, and how different blockchains work together.

Here are a few protocols using ZK tech to power privacy 🔐

→ @aztecnetwork: a zk rollup built for private DeFi
→ @zkemail: prove identity from email or socials without revealing the actual data
→ @noir_lang: a zk-native language for building private smart contracts

And privacy? That’s just the beginning of what ZK can do.

what zk solves:
— privacy: proving things without revealing them
— scalability: verifying huge computations with tiny proofs
— trustless bridging: verify cross-chain actions w/o bridges
— secure automation: agents prove their actions match your intent

How does ZK work?

here’s the simplified version to make it easier for you to understand 

A prover runs a computation privately and generates a cryptographic proof.

A verifier then checks that proof without rerunning the computation and without needing to trust the prover.

The result? Fast, secure, and trustless verification.
