Recently, Vitalik Buterin spoke about the threat of quantum computers in the coming years.

The so-called “Q-Day” may not happen very soon, but in a couple of decades this issue will definitely become critical.

This leads to a logical question:

Does it make sense to buy coins that already have some level of protection against quantum computer attacks?

If even one serious news headline appears about a real quantum computer capable of breaking classical cryptography, many new investors and possibly whales could rush into such coins. Prices of some of them could easily jump several X, or even tens of X, driven by fear, hype, and the desire to protect capital or make fast profits.

After doing my own research, I found the following coins that are related (to different degrees) to quantum resistance:

Quantum-related projects overview

Quantum Resistant Ledger (QRL)
Built from the start as a quantum-resistant network.
Quantum protection is the core of the project, not a future promise.

Algorand (ALGO)
A major blockchain that has taken real steps toward post-quantum (PQ) cryptography in some mechanisms.
However, the whole ecosystem is not fully PQ-secure yet.

QANplatform (QANX)
Strong PQ marketing and claims of a post-quantum architecture.
The key question is how much is already live in production, and how much is still conceptual.

Cellframe (CELL)
A project designed specifically for a post-quantum future.
Uses PQ algorithms at the protocol and infrastructure level.
Main risk: it is a niche project, and adoption may be slow.

Naoris Protocol (NAORIS)
More focused on cybersecurity and trust networks.
PQ is part of the vision, but this is not a coin that is already fully quantum-secure at the transaction level.

IOTA
Has PQ initiatives in identity and security components.
This does not mean regular token transfers are fully PQ-protected.

Abelian (ABEL)
Positions itself as a quantum-resistant blockchain.
Strong focus on PQ cryptography, but as with many such projects, real usage and liquidity matter a lot.

Nervos (CKB)
Not a “quantum coin”.
May discuss or plan PQ topics, but quantum-resistant signatures are not a core focus.

StarkNet (STRK)
Not PQ at the signature level.
Its strength is ZK infrastructure (STARK-based proofs), which is considered more future-friendly in a quantum context.
Wallet signatures are a separate issue.

NEO
Weak as a quantum hedge.
No strong, widely accepted PQ implementations at the network level.

Mochimo (MCM)
One of the older projects that seriously focuses on quantum-resistant signatures for transactions.
However, it is very niche and liquidity can be a problem.

AME Chain (AME)
Looks more like “quantum” branding (quantum randomness, etc.).
Clear proof of PQ-secure wallets or signatures is limited.
Highly speculative.

Ozone Chain (OZO)
Many claims about being “quantum resistant”, but low transparency on technical details and real metrics.
Feels more like a marketing bet with high risk.

I would like to hear your opinion on this topic.

Maybe you have additional or newer information about these projects, or about other quantum-related crypto projects that are worth looking at.
