The news: The future power of quantum computers is a reality that developers anticipate. The solution to protect Bitcoin could be Zero-Knowledge (ZKP), according to the opinion of Felix Xu, CEO of ARPA Network.
1. 🔗 What is Zero Knowledge Proof (ZKP)?
It is the ability to prove that you know something without ever revealing what you know.
🔸️Simple explanation:
Imagine you have the key to a secret locker. You mathematically prove that you possess it without ever showing the key itself.
ZKP guarantees:
▪️Completeness: If you tell the truth, the proof always works.
▪️Soundness: If you lie, the proof always fails.
▪️Zero Knowledge: You learn nothing other than the truth of the proof.
2. ⚡️ The Post-Quantum Shield (ZKP)
The danger of quantum computers is their ability to break the current Bitcoin algorithms based on elliptic curve cryptography (via Shor's Algorithm).
▪️The Problem: The main risk concerns the ability of quantum computers to trace back from your public key to your private key after sending a transaction.
▪️The ZKP Solution: The most advanced ZKPs (like zk-STARKs) use different mathematics called "post-quantum". They are designed to withstand the computational capabilities of future quantum computers.
3. 🌐 The Future Strategy: Integrate ZKPs into Bitcoin
▪️Current Status: No ZKP integration is currently active on Bitcoin's Layer 1. This is a future development path being studied by the community.
▪️The Proposed Method: Integration could be done via secondary layers (Sidechains or Layer 2).
▪️The Goal: These L2s would allow locking BTC on the main network to use in an already quantum-protected environment, without modifying Bitcoin's fundamental code.
📌 In summary: Zero Knowledge technology is not an active shield for Bitcoin, but it is considered the best strategy to ensure its longevity in the face of the future of computing.
Question: Between Privacy (the initial role of ZKPs) and Anti-Quantum Security (its potential future), which application of ZKPs do you find the most fascinating?
