Those interested in quantum resistance should check out QRL. Worth looking into as they've been around for like 8 years now and it's sort of their thing (following NIST guidelines for QR).
Some people hate it, but the quantum computing narrative might play out next alt season. Major correlation between top puic quantum computing company market movements and quantum resistant ledger (QRL).
It is barmy, isnt it? Out of interest, are you following QRL & QTC? Would be great to chat via DM with like-minded folk about this stuff as only a few are paying attention.
QRL certainly will survive. It has been quantum resistant from the first block since 2018.
Put a little in QRL. Exciting times right now with all the quantum computing headlines lately. There's also a promo where if you make a new wallet and head to the discord, there's a whale giving out 10 quanta (valued at $20) no strings attached.
QRL - Quantum Resistant Ledger. The is First Quantumcurrency ever made. QRL is the digital gold of the quantum era.
Centralized systems will and are upgrading. Blockchain is a different story. There exists quantum resistant chains like QRL which has lately been booming.
yep. decentralized systems are uniquely at risk to quantum computing, and the head-in-the sand attitude that most of the people in this thread have are exacerbating the problem. BTC et al. will be likely be slow to respond, and we will see another major crash in price. quantum resistant crypto like QRL will pop in price, then after a rocky road, BTC will probably pop back up with QRL beside it.
QRL - Quantum Resistant Ledger. This is First Quantumcurrency ever made.
as for military contractors specifically, Lockheed Martin filed for a patent about a year ago using QRL to encrypt secure communications
As mentioned in the article, QRL is your best bet in the post-quantum world, as it was made quantum resistant since inception many years ago.
not sure if it's still going on, but the QRL discord was giving out 10 free quanta (valued at $20-$25) to new joiners with proof of a new wallet). anyone interested should look into it.
I wouldn’t say that. Depends on what encryption is in use. ECDSA will be cracked first. SHA-256 will be broken but it will happen later. When it comes to most cryptocurrencies, the lowest hanging fruit for quantum computers is ECDSA. For example, around 25% of all Bitcoin would be in immediate danger, including Satoshi’s coins. The concern is that those wallets could be compromised and the coins dumped on the market. El Salvador recently moved its holdings to new wallets that are better protected, though not quantum resistant in the long term. It’s worth noting that quantum resistant cryptocurrencies already exist. For instance, QRL, which was mentioned in the article, is designed to be secure from the first block, built entirely around quantum safe cryptography. All future crypto must be or become quantum resistant in one way or another.
>They not only provide the first quantum secured coin Nope, that title belongs to Quantum Resistant Ledger (QRL) or Mochimo (MCM), depending on how you're keeping score.
Yes QRL is clearly gaining traction lately. But it is not the only Q-safe crypto, the full list is here: https://coinmarketcap.com/view/quantum-resistant/ Quantum Resistant Ledger did +30% over the past week or so. It will be in the top 100 by next year (listings on more exchanges are planned) and top 10 when shit hits the fan for Bitcoin and Ethereum.
It's nice to see a project like QRL that had a vision and reality is finally catching up to what they foresaw happening. Quantum is here to stay and it will be a part of policy.
The only 2 coins mentioned in the article by name are Bitcoin and QRL
QRL - Quantum Resistant Ledger. QRL is the digital gold of the quantum era.
DCA into QRL. Join the discord and get 10 quanta (valued at $20) deposited into your wallet (with proof of new wallet shared)
Take a look at QRL. Quick pitch: as quantum computers become larger, BTC will need to do a hard fork to protect themselves, which will drive the price down, and the price of QRL up. You're not too late on that one. And they're doing a giveaway right now, 10 for free if you open a new wallet and join the discord.
Continuing to buy QRL
Yes, completely agree. Although I think QRL is very well positioned too. In terms of market cap it is catching up with CKB.
If you don‘t want to jump to funny dog/frog/snake/whatever shitcoins and loose your money the best way is to find a strong narative, Identify the best tokens and invest. For me the narratives i follow are Identity Management (WLD) and quantum Security (QRL, MCM), these are side Investments besides ETH&SOL
IONQ reached 64 qbits earlier than expected and their roadmap is aggressive they expect to read 2,000,000 qbits in 2030s. The companies they bought out are really interesting from satellite quantum internet to diamond lenses used for stabilizing the ions. QRL has been quantum resistant since 2018 and the whitepaper was established in 2016. Since genesis of QRL its quantum resistant. Oddly the price movement of quantum stocks and QRL price have been comparable. It’s not the SHA-256 people need to worry about it’s the ECDSSA that’s used in majority of all blockchains.
I sold my btc at 90k to buy QRL, which has 5Xed since then
ETH&BTC as base Investment - Quantum Token (QRL, MCM, CKB) & WLD as satelites (~20-30%)
Post is by: Original-Assistant-8 and the url/text [ ](https://goo.gl/GP6ppk)is: /r/CryptoMarkets/comments/1nnpryw/the_narrative_of_quantum_computing_is_evolving/ * In **2015**, surveys tended to say *2040–2070*. * By **2020**, the cone shifted to *\~2035–2060*. * By **2023**, consensus compressed to *\~2030–2050*. * In **2025**, after resource-estimate breakthroughs, many forecasts now acknowledge *2027–2045* as the plausible window. Before you say, "this will break everything, crypto is the least of our worries" Do a little more research. We have new cryptography that companies and governments are transitioning to. No matter how small you think the risk may be, the impacts are massive. And hence all systems are forced to prepare. It can no long be framed "a narrative". If you don't have post-quantum cryptography, then you are no longer secure. The reason to consider projects with post-quantum cryptography is not in hopes they will be the next bitcoin. In fact, I will be glad if BTC navigates this and pulls together a solution people can live with to keep the market stronger. The reason for looking at post-quantum coins is two-fold. First, of course the "narrative" will never go away. It just gets stronger every day. And that's because it is a WorldWide problem, not just some crypto use case no one understands. The 2nd is while most projects will inflict damage trying to solve this, coins that are already prepared will be expanding. The quick notes- ETH openly discusses this, but choosing the direction is still up in the air. Obviously it is a major impact to the wide network. Vitalik sees 20% risk in the coming years Many coins like ALGO, HBAR, SOL talk about it, but have not implemented digital signing that protects your wallets. For coins labeled as Quantum Resistant- there is QRL which has been around for 7 years, recently seeing some movement as they will be sending an upgrade in for audit by end of year, and will have a new listing on bitmart. A newcomer Naoris I haven't checked into, but it has done a lot with a marketing push. Recently added to CMCs list of Quantum Resistant coins. QANX, which I hold, is wrapping up audits to launch its public mainnet. They have been building an ecosystem with their enterprise product, which will lead to increased traffic on the public chain. Recent news of Ueno Bank adopting SignQuantum (powered by QAN). Team activity and engagement looks to be picking up as they make their mainnet push. Looking forward to see how that comes together. *I am a bot, and this action was performed automatically.

Quantum Resistant Ledger (QRL)
You must be familiar with QRL
I appreciate the objective, science-based approach. This is exactly how it should be. I strongly encourage you to join the QRL Discord, where you’ll find very detailed and scientifically backed arguments. Super smart people there ready to answer your questions.
If the source is just someone saying it in a discord, that doesn't really inspire much confidence either. Does that person have a good reputation in the field of quantum computing before joining QRL? I mean, I can't corroborate my source's accuracy either, but I at least know my sources are experts in the field and were hired to give their objective thoughts and they are giving those thoughts in a much more public forum where accuracy is generally held to a higher standard. >Personally, I think it’s an important topic, and I’m surprised there isn’t more open discussion around it among crypto communities. The discussion is basically, how much performance do we sacrifice going to our current PQC solutions(and how much we can keep improving them), how quickly can we do it, and when do we need to do it. But the first two things are constantly changing and the last thing is a guessing game, so most people discussing this won't bring anything useful to the table. And all of that is dependent on specific technical knowledge, so it doesn't make sense to do it publicly until it becomes more concrete where the pros and cons are more easily digestible by the public.
Unfortunately Reddit posts don’t allow source links. This was originally shared in the QRL (Quantum Resistant Ledger) Discord. If you join there, you can ask all the hard questions directly. The team and community are usually welcoming all questions and happy to share sources and more details. Personally, I think it’s an important topic, and I’m surprised there isn’t more open discussion around it among crypto communities.
I‘d go for 50% ETH, 30% SOL and 20% Quantum Token (QRL, MCM, CKB) as I like the narative and think they have great opps from 3-5y perspective. Wouldnt invest in baskets, in crypto you should choose your own coins imho
For 100$ only ETH, if investing more I would come up with a 20% stake in quantum Token (QRL and MCM)
80% ETH 10% for QRL and MCM each (love the quantum narative as a BER)
MCM & QRL are my bets - Both with Coming new listings and great narative (quantum Security) which is currently getting more and more attention of the people
Think this will become an issue 5-10y from now - for BTC discussion just started some time ago (BIP360 by Hunter Beast). There are already quantum Secure projects out there - think interesting to Look at. I personally hold some QRL, lets see how this is moving in Future😉
So for the last month you've been shilling QRL a so called quantum resistant crypto, and here you are making FUD posts on "ThE dAnGeRs Of qUaNtUm" This kind of garbage may be able to fool laymen, but to people who have any knowledge of the state of quantum computers and how useless they are at present (and no threat for a decade or two) this is just nonsense.
BTC (almost entirely) HBAR (small portion) QRL (tiny portion)
BTC, ETH, and QRL to hedge against the quantum risk inherent to BTC / ETH. I agree that all the rest is noise.
Bullish on PQ „native“ coins like QRL, CELL, ABEL & MCM - think its a great opportunity from Chance Risk perspective. Don’t believe in Algo & HBAR
Highly recommend quantum resistant coins as well, particularly QRL. Recently down from highs and charts are flashing strong support at current levels. Also long term prospects are fantastic as well
This will be a huge mess for BTC, see scenarios outlined by Deloitte experts in [https://np.reddit.com/r/WallStreetBetsCrypto/comments/1mgf6bl/deloitte\_experts\_warns\_on\_quantum\_risks\_for/?utm\_source=share&utm\_medium=web3x&utm\_name=web3xcss&utm\_term=1&utm\_content=share\_button](https://np.reddit.com/r/WallStreetBetsCrypto/comments/1mgf6bl/deloitte_experts_warns_on_quantum_risks_for/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button) The case of ETH (and the likes) is actually even worse.

Do yourself a favor and look into the existing quantum resistant options. I'm not telling you what to do, but what I did (for my own piece of mind) was put a percentage of my crypto portfolio into a coin called QRL, as it has been quantum resistant since inception and is inherently more secure than anything else out there.
I've only invested in eth once, sold as soon as it made a profit. The whole gas fees thing just blows my mind. So while I hope those die hards make absolute bank, it's not got me and I don't care what happens to it. Think I'll throw a bit of change into QRL though, so thanks for bringing this to my attention as I had no idea about it previously
Yes but you can’t crack QRL and other native quantum safe blockchains… why stick to Bitcoin
Depends, if the L1 is modular it can be more easily integrated than monolithic chains... 🟢QRL>XTZ>ADA>ETH 🟡DOT>ALGO>SUI 🔴BTC>SOL
Quantum safe cryptos already exist (e.g. Nervos, Cellframe, QRL,…)
QRL is designed against quantum attack? are there others? you say they are not correlated. have you calculated their correlation? when a real correction comes (bigger than this week) the alts usually suffer more and everything seems to be correlated in fall (btc, alts, sp500, hell even gold sometimes...) sometimes it seems cash is really the best diversification, gold is great too
Taking profits is normal. Market goes up and down but general trend historically has been up. If you can't handle the swings you should seek to diversify. One of the biggest concerns I have for BTC is the quantum computing vulnerabilities. I have some money in QRL to offset that risk. QRL has been trending up when BTC falls lately, so that is nice. Diversification is common investing advice.
There's a cognitive dissonance at play here explaining why most classical encryption crypto whales are quiet and it's not yet on top 10 exchanges ie Binance/Coinbase, but ahem: [Blackrock Crypto ETF 2025 Quantum Risk Disclosure](https://cryptobriefing.com/blackrock-quantum-risk-bitcoin-etf/) [McKinsey: 2025 The Year of Quantum Report](https://www.mckinsey.com/capabilities/mckinsey-digital/our-insights/the-year-of-quantum-from-concept-to-reality-in-2025#/) Not like this is some tinfoil hat niche anymore. [An XMR dev Luke Parker mentioned QRL by name](https://www.youtube.com/live/jxPulIjhXwg?t=4076&si=NC6TCQzAm1YFBp26) (after wondering out loud whether to "name them") on a recent Monero podcast. The dev called QRL legit bec it's been around for a while and he'd met the team at a conference.
IMO QRL is a quality project that's price is artificially undervalued because of the difficulty to obtain. They use a quantum resistant signature that most tier 1 exchanges would have to do extra work to get listed, so until they hit critical mass the price is suppressed. As someone else stated, if you want to make money, find a quality project and DCA over time. If you're a chart guy, they just had a pull back to some key support levels and now is actually a "good time" to buy. Join the discord if you have questions on the bullish case and what to expect. https://theqrl.org/discord
Sell some BTC to take profits and hedge against common risks. Makes sense to buy something like QRL right now (Quantum Resistant Ledger) as the upside is ~350x whereas BTC upside is like ~7x in the next 5-10 years.
QRL just found a strong support level about 3 days ago
ETH, SOL, QRL —> my Major Holdings
What are your thoughts on QRL? Does quantum resistant cryptography have a place in this crypto market?
QRL (Only coin with Post-tQuantum specific encryption) World Coin (Major integration and defi functionality in the pipeline and major artificial intelligence implications) BSV (Only Bitcoin fork that can provide the TPS required for worldwide adoption)
QRL has dropped like 40% from its recent high, currently consolidating, and poised to jump back up rather quickly. Check out the discord since that's a lot more active than the subreddit.
QRL. Not a top 100 yet but tons of upside. Check out the discord.
QRL uses XMSS encryption, which is quantum resistant. It's worth a look if you're interested.
Any thoughts on QRL (Quantum resistant ledger)? Is it just a hype or is this crypto truly Quantum resistant? When I visit their sub, they say it is the future.
I will definitely look into QRL . Also thank you, I’m interested in the science and maths. Also to have a real discussion. Not others who just seems to want to throw insults
Bitcoin addresses will be hacked. A hard fork will only solve the problem for addresses created after the fork. There are existing blockchains that utilize post-quantum encryption. Look into [QRL](https://www.theqrl.org/blog/celebrating-seven-years-of-qrl-ahead-of-the-quantum-curve/)
QRL was released in 2018, and has used quantum resistant encryption from the beginning. They’re working on an EVM friendly chain called Zond, set to release sometime next year.
One interesting thought experiment is to do a "pre-mortem". Imagine a scenario where your current investment fails and the explain to yourself why it happened. When asked, the top two concerns around Bitcoin people have are either government regulation or quantum computing making old BTC them vulnerable to hacks. I personally think we're good for a few years government-wise (at least as far as this administration is concerned). The quantum threat is more concerning to me. Check out the QRL (Quantum Resistant Ledger) discord if you're curious to hear more about the bull case. There was a surge in price recently but it's down 30% from that high and probably actually a good time to buy in.
Consider investing a small amount ($50–100) in a quantum-resistant crypto like QRL. When quantum computers inevitably break current encryption, that small hedge could become the most valuable investment you ever make.
Conservatively? Absolutely nothing. I’d wait until the next dip and buy ETH. Realistically? I’m putting my chips on QRL and it’s not even close. Downvote me all you want, but throw me a “remind me 5 years” and we’ll see where it’s at. But it’s a bet I’m completely comfortable making.
QRL has what is probably the greatest endorsement in blockchain history. A patent filed by Lockheed Martin. It's the first Quantumcurrency. Quantum Secure since genesis. Absolutely legitimate blockchain.
https://www.reddit.com/r/QRL/s/gCrenroVF2 Yeah I realize that. But will bitcoin still be the infallible “one?”
https://www.reddit.com/r/QRL/s/gCrenroVF2 I’m not so sure. This is a good read though…. Banks, centralized military and other institutions will be able to implement solutions. Bitcoin with its decentralization will need a fork and need consensus. Might be another bitcoin/BCH/bitcoin gold etc issue.
HBAR has some bullish momentum and could definitely see some more upside. There's been some whale accumulation recently that could be bullish as they might know something we don't "wallets holding **$10 million+ in HBAR** climbed from **81.72% to 87.56%** of total supply" per a beincrypto article. I would question TAO as it's mostly an AI hype play and that seems to have run its course. I could be wrong but sentiment seems negative there. One project I'm very bullish on is QRL - they're a quantum play in the space and have been around since 2018 (not well known as they've been prioritizing fundamentals over marketing). They developed the first blockchain designed from the ground up with post-quantum cryptography (XMSS), anticipating the threat quantum computers pose to traditional cryptos. The QRL community has been very active lately (making up for lost time in the marketing space) and it's starting to catch on. Anyway, looks like a decent spread! Maybe replace TAO with QRL and you're good to go :D!
I don't have much crypto but my plan is to just steady DCA into BTC and ignore price. Have had a similar strategy for QRL for years. Just base decisions on belief in the tech.
ETH —> Future of everything QRL —> will retire me in 3y, as quantum threat discussion is coming HBAR —> quite interesting project, to be tracked very closely
QRL - Quantum Resistant Ledger (Wallets won’t get cooked) BSV - Bitcoin Satoshi Vision (High TPS, potential for growth as high adoption becomes the norm and people look for the Bitcoin name) Monero - (Privacy)
This really feels like hearing about Bitcoin in 2011 or so. Quantum computers are gonna change the whole industry, and it's just getting started. There is no better time to start reading about QRL.
Whether anyone thinks the threat of quantum computers is real or not, what do you have to lose by investing a small amount in QRL ?
Take a look into QRL - they are set up as the best play for crypto owners to buy to hedge against the quantum computing risk and they are seeing a lot of fresh interest in the last month.
$QRL is following a completely different narrative and has a ton of growth potential. Big money is slowly trickling in. It's a top 500 coin that belongs in the top 10. Imo, if you're looking for 10x gains, $QRL is worth checking out.
Now do the same but between Nano and QRL (Quantum Resistant Ledger) :3
I bought $250 worth of QRL last month just in case quantum computing breaks encryption before BTC and ETH are ready for it. Not really FOMO, just hedging my bets a little bit.
Ich bin in den Discord-channels/communities/… aller genannten Coins unterwegs - QRL hat imo mit Abstand die stärkste Community der genannten Projekte. Breites Team mit starkem Knowledge, gute Finanzierung, und m.E. das beste Narrativ. —> 65% meiner PQ-crypto Cellframe - Macht auf mich nen leicht shady Eindruck, aber gutes Narativ —> 15% Anteil MCM - starkes Produkt, aber ultrakleine Community (hängt gefühlt an 2-3 Köpfen) und schlechte Finanzierung und keine Liquidität—> 10% Anteil Abel & CBK - wenig Aktivität der Community, bei CBK hab ich den Ansatz noch nicht wirklich durchschaut —> beide <5% Anteil Ich finde das Chance-Risiko Verhältnis bei den Projekten extrem attraktiv, die ersten drei Token haben eine Market Cap <60 m$, die Szenarien in denen das auf 6bn, 60bn,… gehen kann sind für mich sehr greifbar. Ein Tier 1 listing verbunden mit Quantum Secure Aktivitäten bei BTC/ETH/o.ä. und die genannten Zahlen sind nicht in weiter Ferne. Bei allen Token reden wir über eine extreme Konzentrierung auf einige wenige Wale, was als zusätzlicher Katalysator in einem Aufwärtstrend wirken kann. To the Moon… 😉
Nowadays there is some new breakthrough every few weeks. You can join the #quantum-news channel on QRL Discord ( https://www.theqrl.org/discord ) or check some (less updated) news on website ( https://www.theqrl.org/quantum-news/ ).
That's an ERC20 token mostly not quantum secure. QRL is the only viable hedge
Time to start hedging with QRL. Thank me later.
Mochimo as a pioneers without any ico in quantum resistant niche, followed by QRL and cellframe. All very small market cap coins with enormous potential when Qday arrives.
Bitcoin doesn't need to hard-fork to add new asymmetric digital signature algorithms. Schnorr was added as a soft fork There's a recent obsession with making existing QC vulnerable unspent coins unspendable. That would be a hard fork. But that's not a discussion about quantum computing. It's a choice between mandatory coin burning and allowing spending by QC The elephant in the room is a technical one (conveniently ignored by the QRL fan's comment). A scheme like XMSS (his example) has a signature which is 38 times larger than Bitcoin's current signatures More important, it takes 50x more compute time to verify each signature. For each new block, every Bitcoin node verifies every signature in every transaction input - roughly 5000 txinputs per block. Currently, it takes a node about 9 seconds to verify a block (including the thousands of signatures), and the node network's topology is 3 or 4 layers deep. Full propagation of a new block takes in the order of 43 seconds. In the context of Bitcoin's 10-minute average block interval, the current propagation time is optimal This issue is completely absent from the OP's linked paper. The paper appears to have been written by "Doctors" with a weak understanding of the decentralization aspect of Bitcoin Also, the paper contradicts itself in the discussion about SHA256 hashing - stating that QC hashing isn't a risk to Bitcoin mining, and then claiming that it is. This type of contradiction is a common feature of research papers written partially by LLM engines The paper's justification for predicting a short QC timeframe is very shallow, not based on the reality of the incredibly slow progress of QC research
This Chaincode report is one of the clearest overviews I've seen on Bitcoin’s current vulnerabilities to quantum computing. It emphasizes how Bitcoin's ECDSA signatures are the weakest link—public keys become exposed once coins are spent, and Shor's algorithm could theoretically break those with a sufficiently powerful quantum computer. What’s particularly interesting is how the report proposes proactive migration strategies, though they hinge on user coordination and optional upgrades, which Bitcoin has always been slow to adopt. The reality is that unless there's a hard fork or some kind of universal upgrade path, a lot of coins (including Satoshi's) will remain vulnerable. This is where something like the Quantum Resistant Ledger (QRL) becomes relevant. QRL was built from the ground up using post-quantum secure signature schemes (XMSS, approved by NIST), not just tacked on as an afterthought. That said, it’s going to be tough for Bitcoin to shift gears without compromising some of its principles.
Nothing crazy about it. Bitcoin is the first blockchain. QRL is the first Quantum Resistant Blockchain.
Agree! QRL is the way! Quanta>Satoshis. Keep stackin' the Quanta!
Anyone with significant holdings of crypto and no QRL is a bit crazy, IMO.
