Which Cryptos Are Quantum Resistant? A Clear Guide for 2026
Which cryptos are quantum resistant? The honest answer is that most major chains, including Bitcoin, Ethereum, and Solana, are not. They rely on ECDSA or Ed25519 signatures, which are vulnerable to quantum attacks. In contrast, genuinely quantum-resistant designs use NIST-standard post-quantum algorithms like CRYSTALS-Kyber for key encapsulation and CRYSTALS-Dilithium for signatures. BMIC, a presale project, implements CRYSTALS-Kyber class KEM and provides a working quantum-resistant wallet free with purchase.
Part of the BMIC quantum series. For the full background — the threat, the NIST standards and the buying checklist — start with the quantum crypto presale guide.
How to check any coin's quantum status in 5 steps
- Check the signature schemeVerify whether the crypto uses post-quantum signatures like CRYSTALS-Dilithium or vulnerable schemes like ECDSA.
- Look for key encapsulationEnsure the crypto uses post-quantum key encapsulation, such as CRYSTALS-Kyber, to protect encryption keys.
- Avoid reused addressesAddresses that have never spent offer an extra hash layer of protection against quantum attacks.
- Understand the risksRecognize that 'harvest now, decrypt later' attacks mean the quantum risk begins today, not just on 'Q-Day.'
- Verify the walletEnsure the crypto provides a quantum-resistant wallet that uses NIST-standard post-quantum cryptography.

Why Most Cryptos Aren’t Quantum Resistant
Bitcoin and Ethereum rely on ECDSA (secp256k1) signatures, while Solana uses Ed25519. None of these schemes is quantum-resistant; all are breakable by Shor’s algorithm on a large, fault-tolerant quantum computer. A 2022 University of Sussex study estimated roughly 13 million physical qubits to break Bitcoin’s ECDSA within a day and 300 million within an hour. Today’s quantum hardware, like IBM’s Condor processor with 1,121 physical qubits, is far from this scale. Grover’s algorithm halves symmetric/hash security, so mining and hashing are less exposed than signatures. However, 'harvest now, decrypt later' attacks mean adversaries can record encrypted data today and attack it later.
What Makes a Crypto Quantum Resistant?
A genuinely quantum-resistant crypto uses NIST-standard post-quantum algorithms. NIST finalized three standards on August 13, 2024: FIPS-203 (ML-KEM, based on CRYSTALS-Kyber for key encapsulation), FIPS-204 (ML-DSA, based on CRYSTALS-Dilithium for digital signatures), and FIPS-205 (SLH-DSA for hash-based signatures). Key encapsulation protects encryption keys, while signatures secure transactions. BMIC implements CRYSTALS-Kyber class KEM, ensuring its encryption is quantum-resistant. Its wallet, which comes free with purchase, uses this NIST-standard cryptography. Avoid cryptos that rely on ECDSA or Ed25519, as these are not post-quantum.

Frequently asked questions
Is Bitcoin quantum resistant?
No, Bitcoin uses ECDSA signatures, which are vulnerable to quantum attacks.
Bitcoin’s ECDSA signatures can be broken by Shor’s algorithm on a large quantum computer. A 2022 study estimated 13 million physical qubits could break Bitcoin’s ECDSA within a day.
What is 'harvest now, decrypt later'?
It’s when adversaries record encrypted data today to decrypt it later with quantum computers.
This strategy means the quantum risk begins now, not just when quantum computers become powerful enough to break cryptography.
How does BMIC ensure quantum resistance?
BMIC uses NIST-standard CRYSTALS-Kyber class KEM for key encapsulation.
BMIC’s encryption is protected by CRYSTALS-Kyber, a NIST-standard post-quantum algorithm. Its wallet is audited and free with purchase.
Can I buy BMIC without crypto?
Yes, BMIC accepts card payments in addition to ETH via MetaMask.
BMIC’s presale supports card checkout, making it accessible even if you don’t hold crypto. Tokens are claimable after the TGE.
