A blockchain that uses Zero-Knowledge (ZK) proof technology is a next-generation system that allows users to prove something is true without revealing the actual data behind it.
👉 In simple terms:
You can verify information without exposing sensitive details.
🧠 What is Zero-Knowledge (ZK) Proof?
Zero-Knowledge Proof is a cryptographic method where:
One party (the prover) proves something
Another party (the verifier) confirms it
❗ Without learning any extra information
Example:
You can prove:
“I am over 18”
without revealing your exact age or birthdate.
⛓️ How ZK Works in Blockchain
Traditional blockchains (like Bitcoin or Ethereum):
Are transparent
Show transaction details publicly
ZK-based blockchains:
Keep transactions private
