**📌 2025: quantum computers are already here. 80% of blockchains are vulnerable. Who will stay afloat?**
### **🔍 3 blockchains that are already preparing for the quantum revolution**
#### **1️⃣ QANplatform — quantum-resistant Ethereum**
- **What does it do?** The first L1 with a **hybrid quantum-resistant algorithm** (CRYSTALS-Dilithium).
- **Why is it important?**
- Even Google Quantum Computer 2025 won't break its encryption.
- Full compatibility with EVM — can migrate from ETH in 1 click.
- **Risks**: Small ecosystem (for now).
#### **2️⃣ Algorand 3.0 — "silent killer" of Ethereum**
- **Feature**: Uses **Post-Quantum cryptography** since 2023.
- **Why is it not liked?**
- Boring marketing (no memes, just technique).
- But... **4000 TPS + zero fees** — that's serious.
- **Forecast**: Could become the "corporate standard" after ETH declines.
#### **3️⃣ Hedera Hashgraph — dark horse**
- **What impresses?**
- **Not a blockchain, but a DAG** (on graphs) — quantum attacks are almost impossible.
- Partners: Boeing, LG, Google.
- **Minus**: Decentralization in question (node controlled by a council of corporations).
### **💥 What about Bitcoin and Ethereum?**
- **BTC**: Vulnerable to Shor's attacks (breaks ECDSA in 8 minutes). Solution? **Soft fork with new cryptography** — but this will be a war.
- **ETH**: L2 (Arbitrum, zkSync) are already testing quantum-resistant solutions. But ETH L1 itself is "in the crosshairs".
### **📌 Conclusions**
- **For investors**: Looking at **QAN, ALGO, HBAR** — this is insurance for 5+ years.
- **For developers**: Learn **quantum-resistant standards** (NIST has already approved algorithms).
