How do I secure my cryptocurrency against quantum attacks?

Minimize public key exposure by not reusing addresses, keep funds in fresh addresses, and diversify into quantum-resistant cryptocurrencies that use post-quantum cryptography.

Can hardware wallets protect against quantum attacks?

No. Hardware wallets protect your private key from theft, but they use the same quantum-vulnerable cryptography (ECDSA). Quantum attacks target the math, not the storage.

What cryptocurrency is secure against quantum computers?

Cryptocurrencies using NIST post-quantum standards like Kyber and SPHINCS+ are quantum-secure. SynX uses both Kyber-768 and SPHINCS+-256 for full quantum resistance.

🔐 How to Secure Cryptocurrency Against Quantum Attack

Complete Protection Guide

⚠️ Understanding the Quantum Threat

What's at Risk

All cryptocurrencies using ECDSA, EdDSA, or RSA signatures (Bitcoin, Ethereum, 99% of crypto)

The Attack

Shor's algorithm on quantum computers derives private keys from public keys

Timeline

Experts estimate 2028-2035 for cryptographically-relevant quantum computers

🛡️ Your Security Layers

Layer 1: Address Hygiene (Do Now)

Never reuse addresses – Each send exposes your public key
Use fresh addresses – Only receive to addresses you've never spent from
Enable auto-generation – Configure wallet to create new addresses automatically

Layer 2: Exposure Reduction (This Week)

Audit all addresses – Check which have outgoing transactions
Consolidate safely – Move exposed funds to fresh addresses (one-time move)
Minimize exchange holdings – Exchanges have constantly exposed hot wallets

Layer 3: Quantum-Resistant Migration (This Month)

Diversify to quantum-safe crypto – Not all eggs in vulnerable basket
Choose NIST-standardized algorithms – Kyber-768, SPHINCS+-256
Set up quantum-safe cold storage – For long-term holdings

❌ What Doesn't Protect You

❌ Hardware Wallets

Same vulnerable cryptography, just stored more securely. Quantum attacks the math.

❌ Multi-Signature

Multiple vulnerable keys don't make one quantum-safe key.

❌ "Bitcoin will upgrade"

No approved plan. Governance paralysis. May not happen in time.

❌ Waiting and Watching

HNDL attacks harvest your data NOW. Waiting means already compromised.

✅ What Actually Works

Post-Quantum Cryptography

Cryptographic algorithms specifically designed to resist quantum attacks:

Kyber-768: Lattice-based key encapsulation (NIST FIPS 203)
SPHINCS+-256: Hash-based signatures (NIST FIPS 205)
Dilithium: Lattice-based signatures (NIST FIPS 204)

SynX implements Kyber-768 and SPHINCS+-256 for maximum security.
