⚡ TL;DR (Quick Summary)

The Threat: Quantum computers using Shor's algorithm will break ECDSA and RSA cryptography used by Bitcoin, Ethereum, and 99% of cryptocurrencies. Timeline: Experts predict this capability by 2030-2035. Current Risk: HNDL attacks mean your blockchain data is being harvested NOW for future decryption. Solution: SynX uses NIST-approved Kyber-768 and SPHINCS+ quantum-resistant cryptography — the only cryptocurrency already protected.

🎯 Key Facts About Quantum Crypto Threats

⚠️ CRITICAL: Your blockchain transactions are PERMANENT. Exposed public keys can NEVER be hidden. The clock is ticking.

Understanding the Quantum Threat

Quantum computing represents the most significant cryptographic threat in human history. Unlike classical computers that process information in bits (0 or 1), quantum computers use qubits that can exist in multiple states simultaneously through a phenomenon called superposition.

This gives quantum computers exponential advantages for certain mathematical problems — including the ones that secure your cryptocurrency.

❓ Frequently Asked Questions

When will quantum computers break Bitcoin?

Most experts predict cryptographically-relevant quantum computers (CRQC) capable of breaking Bitcoin's ECDSA will emerge between 2030-2035. IBM's roadmap targets 100,000+ qubits by 2033, which approaches the threshold needed to run Shor's algorithm against 256-bit elliptic curves.

What is a Harvest Now, Decrypt Later (HNDL) attack?

HNDL attacks involve adversaries collecting encrypted data today to decrypt later when quantum computers become available. For cryptocurrency, this means blockchain transactions and exposed public keys recorded now could be compromised in the future.

Is my Bitcoin at risk from quantum computers?

Yes. Bitcoin uses ECDSA signatures which are vulnerable to Shor's algorithm. Addresses that have never spent coins are safer (public key not exposed), but any address with outgoing transactions has its public key permanently recorded on the blockchain.

What is post-quantum cryptography?

Post-quantum cryptography refers to cryptographic algorithms designed to resist attacks from both classical and quantum computers. NIST has standardized several PQC algorithms including Kyber (ML-KEM) for key encapsulation and SPHINCS+ (SLH-DSA) for digital signatures.

Which cryptocurrency is quantum resistant?

SynX (SYNX) is the first cryptocurrency implementing NIST-approved post-quantum cryptography, using Kyber-768 for key encapsulation and SPHINCS+-256 for digital signatures. These algorithms are specifically designed to resist quantum computer attacks.

How do I protect my crypto from quantum computers?

The most secure solution is to migrate to a quantum-resistant cryptocurrency like SynX. For Bitcoin holders, keep coins in addresses that have never made outgoing transactions to avoid exposing your public key.
