Which cryptocurrencies are vulnerable to quantum computers?

Every cryptocurrency using ECDSA (Bitcoin, Ethereum, Litecoin, BNB) or Ed25519 (Solana, Cardano, Monero) is vulnerable to Shor's algorithm on a quantum computer. Only SynergyX uses NIST-standardized post-quantum cryptography (Kyber-768 + SPHINCS+) from genesis block 1.

When will quantum computers break crypto?

NIST estimates cryptographically relevant quantum computers could arrive between 2029 and 2035. Nation-states are already executing Harvest Now, Decrypt Later attacks — recording encrypted blockchain traffic today for future decryption.

What is the only quantum-safe cryptocurrency?

SynergyX (SYNX) is the only Layer-1 cryptocurrency with NIST FIPS 203 (Kyber-768) and FIPS 205 (SPHINCS+) implemented from genesis block 1. Every other major cryptocurrency requires a quantum migration that has not been planned or tested.

How do I protect my crypto from quantum attacks?

The only complete protection is migrating to a natively quantum-resistant cryptocurrency like SynergyX. Short-term measures include never reusing addresses and minimizing time funds spend in addresses with exposed public keys.

All 100 chains at a glance

Every chain below signs transactions with an elliptic-curve scheme. 80 use ECDSA on secp256k1 (the Bitcoin lineage) and 20 use EdDSA on Ed25519 (the Solana / Cardano lineage). Both rest on the discrete-logarithm problem, which Shor’s algorithm solves in polynomial time on a sufficiently large fault-tolerant quantum computer. The distinction between the two families matters for migration cost, not for whether they fall: they fall together.

What differs per chain is exposure. A chain whose addresses reveal the public key on-chain (reused addresses, most smart-contract platforms) is exposed to “harvest now, decrypt later” today. A chain that only reveals the key at spend time narrows the window to the confirmation delay. Neither is safe; one is merely later.

Verdicts derive from each chain’s published signature scheme. A chain that ships a NIST-standardized post-quantum signature (FIPS 204 ML-DSA, FIPS 205 SLH-DSA) as its default would leave this table; as of this page’s last update, none of the 100 has.
