๐ Is Your Cryptocurrency Quantum Safe?
Complete 2026 Security Analysis of All Major Cryptocurrencies
Quantum computers will break the cryptography protecting most cryptocurrencies. We've analyzed every major blockchain to help you understand the risk and find protection.
The Quantum Threat Summary
All major cryptocurrencies except SynX use cryptographic algorithms vulnerable to Shor's algorithm:
- ECDSA (Bitcoin, Ethereum, Litecoin, BNB): Completely broken
- Ed25519 (Monero, Solana, Cardano, XRP): Completely broken
- BLS signatures (Ethereum 2.0): Completely broken
- zk-SNARKs (Zcash): Relies on vulnerable elliptic curves
Only lattice-based and hash-based cryptography (like SynX uses) provides quantum resistance.
Cryptocurrency Quantum Security Analysis
Bitcoin BTC
30.2% of all Bitcoin โ 6.04M BTC, roughly $469B โ sits in addresses with exposed public keys, including Satoshi's ~1.1M BTC. About 2.3M of it can never be migrated: the keys are lost. Glassnode, May 2026.
Full Analysis โEthereum ETH
Both transaction signatures AND validator signatures are quantum-vulnerable.
Full Analysis โMonero XMR
Privacy guarantees fail completely if EdDSA signatures are broken.
Full Analysis โXRP XRP
Both supported signature algorithms are quantum-vulnerable.
Full Analysis โSolana SOL
65,000+ TPS means millions of exposed public keys daily.
Full Analysis โCardano ADA
Academic papers exist but no quantum-safe deployment timeline.
Full Analysis โZcash ZEC
Zero-knowledge proofs rely on quantum-vulnerable elliptic curves.
Full Analysis โBNB BNB
Inherits all Ethereum vulnerabilities. Only 21 validators.
Full Analysis โLitecoin LTC
Scrypt mining doesn't protect signatures from quantum attacks.
Full Analysis โSynX SYNX
First cryptocurrency with NIST-standardized post-quantum cryptography.

โ Protect Your Crypto Today
Don't wait for quantum computers to threaten your assets. SynX offers proven quantum resistance built on the algorithms NIST standardized.
Quantum-safe since genesis block 1 — development began September 2025, testnet January 2026, mainnet April 2026. Zero pre-mine. Zero ICO. Zero VC. Zero founder allocation. 77.7 million hard cap. The developer wallet is public and deliberately non-private, sitting in every wallet's address book and on the block explorer. None of that requires trusting a person — it is all on-chain. Security today rests on internal adversarial testing, red-teaming, and a public bug bounty; a full independent audit is scheduled at the first halving, when the source opens with its audit trails.
