Interesting move from a post-quantum-secure crypto named QRL
It's time to think about what threat Quantum Computers have agains crypto
Will Ethereum 2.0 be safe against Quantum Computers or will there be another update that takes years for that in the future?
Will Ethereum 2.0 be safe against Quantum computers and what about other coins?

Alt that have no utility has always been dead. Only crypto worth buying at this point is Bitcoin and QRL
Bitcoin is quantum vulnerable garbage. QRL is the digital gold of the quantum era. A chain that wasn’t secure at genesis can never be fully secure later.
Good step - they just missed to mention the already quantum resistant projects (not listed on Coinbase 😉) like QRL, MCM, ABEL. Google didn’t have issues to mention them…
Interesting, still it’s not mentioning already Quantum Secure projects (not listed on Coinbase 😉) Like QRL, MCM, ABEL
Just did. This is the response “QRL (Quantum Resistant Ledger) is widely considered the clearest leader — launched in 2016 and built entirely around post-quantum security from day one using XMSS (hash-based) signatures. It remains one of the few coins where quantum resistance is the main thesis, not a side feature.”
Think it’s a good opportunity as a hedge, in this sector I invest in QRL (main Portion), MCM (hell difficult to invest, only listed in one Minor Exchange) and ABEL. All of them are small/micro. cap with great chance / risk profile imho
NIST has already finalized their standards. “algorithms include ML-KEM (formerly CRYSTALS-Kyber) for general encryption, and ML-DSA (CRYSTALS-Dilithium) and SLH-DSA (SPHINCS+) for digital signatures, with FALCON as an additional signature standard” From what I gather from the Google paper, QRL is the only project that is currently quantum safe. Been looking into investing in it.
I‘d go for 30% BTC, 30% ETH & 40% in bets based on current Trends like quantum Secure (e.g. QRL, ABEL), Identity (e.g. WLD) & others
QRL :) quantum resistant ledger , ils vont bientôt passer en PoS
Not sure if the 10$ criteria is the best one - but let me bring three candidates in, all from the „Quantum Secure sector“ (think it’s the hottest topic in crypto nowadays) QRL, MCM & ABEL, all Micro Caps with huge upside potential imho
They also mentioned that other cryptocurrencies were quantum resistant from genesis, such as QRL. I think that's a nice metric to have.
BTC, QRL. That’s it, nothing else is needed
I think they called out the mitigations they are testing and trying to implement…but it isn’t quantum safe yet. “Fortunately, there is a path to achieving post-quantum security for cryptocurrencies. PQC has become a mature cryptographic discipline: post-quantum cryptosystems have been proposed, scrutinized, implemented and deployed. 5 In fact, they are in active use protecting Internet traffic [61] and indeed securing blockchain transactions [62]. As we discuss in detail in later sections, some blockchains, such as the Quantum Resistant Ledger (QRL) [63, 64], Mochimo [65] and Abelian [66], rely exclusively on PQC. Others, such as Algorand, the XRP Ledger, and Solana, have made early experimental deployments of post-quantum protocols [62, 67]. However, forward-looking migration to PQC is not a panacea. Dormant digital assets, including those abandoned or inaccessible due to lost private keys, pose a distinct and critical challenge. We highlight the example of Bitcoin’s Pay-to-Public-Key (P2PK) locking scripts, which secure over 1.7 million BTC. The total amount of dormant quantum- vulnerable bitcoin may reach 2.3 million BTC when all script types are considered. Unlike active wallets that can migrate to new standards, dormant assets cannot be “fixed” via forks that enable PQC protocols for future transactions. They represent a fixed target — tens or hundreds of billions of dollars in value that will eventually become accessible to a quantum attacker. The community will soon face difficult, unprecedented decisions regarding the fate of these assets, forcing tradeoffs between the immutability of cryptographic property rights and the economic stability of the network.”
$QRL exists for a reason
You guys should check out QRL. It was also mentioned in the google paper. Quantum safe since the first block!
Lockheed Martin, the defense contractor, actually has a patent using QRL for post quantum secure communications. Here’s the link if you want to check it out: https://patentimages.storage.googleapis.com/78/80/e3/60548f2a111c0a/US20240048369A1.pdf
That’s why I own QRL. Recently feeling validated as it was mentioned in the Google paper!
Look into the crypto coins IOTA and QRL, I’m too high rn to remember the full explanation. lol but apparently there allready ahead of this. Somehow they have un-breakable encryption by quantum computing, was just talking to AI about this.

centralized institutions can upgrade to PQ encryption easily, crypto cannot. thats why some quantum resistant projects like Qanplatform and QRL have been working on this for a few years
My point was that even with no forks the current version of Ethereum won’t be susceptible to the first few waves of quantum attacks. Bitcoin on the other hand has a problem because it takes so long to finalize transactions. Again… nothing against QRL. It’s just that pretty major every chain besides Bitcoin is already in good shape.
You're not wrong about any of this but tbh I don't think it matters in the long run. Ethereum and L2's will be fully quantum resistant in \~5 years... but here's the thing. Even by the most progressive estimates it will take \~9 minutes for quantum computers to break ECDSA-256 signatures once powerful enough hardware exists. An ETH transaction is confirmed in about 15 seconds (soon much, much faster). A quantum attacker cannot see your transaction in the mempool, crack your key, and send a fake transaction fast enough to outrun a real transaction before it's confirmed. I have nothing against QRL (I think it's cool) but in reality by the time a real threat emerges ETH and all these other chains will also be fully quantum resistant. Even in their current states quantum computers wouldn't pose much of a threat. Basically... I don't think it's worth investing in quantum resistant coins.
Post is by: Hot_Local_Boys_PDX and the url/text [ ](https://goo.gl/GP6ppk)is: /r/CryptoMarkets/comments/1sbezmv/how_coinmarketcap_manipulates_quantumresistant/ Posting on behalf of someone else: >I started looking into CoinMarketCap’s “quantum-resistant” category, and the whole thing looks ridiculous. First problem: Zcash is not quantum-resistant today. It still relies on elliptic curve cryptography in important parts of the system, which is exactly the kind of cryptography quantum computers are meant to break. Calling it “quantum-resistant” right now is misleading Second problem: Starknet is an L2. Even if some parts of it are more resistant than older systems, it still sits on top of a Layer 1 world that is not fully quantum-safe. Putting it high on the list without that context is misleading too. Third problem: Qubic is questionable as well. Its own materials talk more about adaptation and future resistance than about already being a fully quantum-resistant blockchain. That is not the same thing as being truly post-quantum today. Fourth problem: QRL got buried. This is where it starts looking less like sloppy categorization and more like market interference. QRL was built specifically around the quantum threat from the beginning, so by actual relevance it should be near the top of this category, especially if the unrelated or weakly related projects were removed. Instead, it got pushed down to around rank 4000 after spending years around the top 200–400 range. Then CMC said the market cap was not verified, even though the team says they provided the required documents. And when asked publicly, the response suddenly shifted into talk about liquidity ratios and tier 1 exchanges. That is not a clear explanation. That sounds like moving the goalposts. Fifth problem: Algorand is missing completely. That alone makes the section look broken. If projects with weaker or more questionable claims can get into the category, how is Algorand not even there? At this point the category does not look like neutral data. It looks curated in a way that shapes perception. And that is the bigger issue here: CoinMarketCap has enormous power over visibility in crypto. If they rank you high, people see you. If they bury you, you effectively disappear. Most retail users are not reading whitepapers or checking cryptography details. They look at CMC categories, rankings, tags, and market cap. So when CMC puts questionable projects at the top, leaves relevant ones out, and pushes down one of the few actually quantum-focused chains, that is not some harmless metadata mistake. That changes who gets attention, who gets volume, and who gets taken seriously. That is why the QRL situation looks so bad. QRL is a small project already fighting an uphill battle in a market full of hype, exchange favoritism, and paid visibility. If CMC strips away ranking credibility and then starts implying the fix is better liquidity or tier 1 listings, that feels less like objective analysis and more like gatekeeping. And because CMC is owned by Binance, people are obviously going to question whether this system is fair at all. Honestly, this is what makes crypto exhausting. Everyone talks about decentralization, fairness, open markets, and permissionless competition. But in reality, a few giant platforms still act like gatekeepers. They decide what gets seen, what gets buried, and what narrative retail investors are supposed to believe. A project can spend years building around a real problem, and one ranking decision can wipe out its visibility overnight. So no, maybe nobody can prove intent from the outside. But from the outside it absolutely looks like CMC is diminishing projects while inflating the credibility of a broken “quantum-resistant” category. And when a platform with that much influence keeps making “mistakes” in one direction, people are going to stop calling them mistakes. \--- TL;DR: CMC’s quantum-resistant category looks broken. Zcash still depends on ECC, Starknet is only an L2, Qubic does not clearly qualify as fully quantum-resistant, QRL got buried with vague excuses about verification and liquidity, and Algorand is missing entirely. At some point this stops looking like incompetence and starts looking like a platform shaping the market. *I am a bot, and this action was performed automatically.

Just came across this CoinDesk article and it got me thinking: https://www.coindesk.com/markets/2026/04/01/the-first-winners-of-the-quantum-crypto-debate-are-already-clear-and-some-of-them-are-up-50 Key points: Google suggests Bitcoin’s cryptography could be broken with ~500,000 qubits (lower than expected) Still theoretical, but markets are reacting NOW Quantum-resistant tokens like QRL (+50%) and $CELL (+40%) are already pumping What’s interesting is this feels similar to early AI narratives — the tech isn’t fully here yet, but capital is positioning early. From a technical perspective: Post-quantum cryptography isn’t just a “feature,” it’s a complete redesign of how blockchain security works. That’s why projects like Cellframe ($CELL) are getting attention — they were built with this in mind from the start. Question for the community: Do you think quantum resistance becomes a major investment thesis this cycle, or is this just short-term hype? Curious to hear thoughts, especially from people deeper into cryptography.
Apparently QRL even higher
If you're getting ready for an interview about QRL 2.0 or its tech, make sure you understand the differences between proof-of-stake and proof-of-work, especially when it comes to security and scalability. Also, learn about post-quantum cryptography and why it's important for blockchain. You might need to know how Hyperion compares to Solidity and what it means that QRVM is a fork of EVM. If you want more structured prep or mock interviews, I've used [PracHub](https://prachub.com/?utm_source=reddit&utm_campaign=andy), and it was pretty helpful. Good luck!
QRL is moving from a PoW, XMSS signature infrastructure (fundamentally different from the Elliptic Curve cryptography used by almost every other chain and thus difficult to integrate) to a PoS infrastructure with an Ethereum-compatible API. Named “Zond”, once fully live (with Testnet V2 having launched in Q1 2026), it will allow exchanges to treat QRL much more like an Ethereum-based chain, drastically lowering the technical barrier to entry. It’s currently being audited and, should it pass, mainnet will be released shortly after. Additionally, it’s been quantum resistant since its inception. **There isn’t a single wallet that will be susceptible to quantum attacks.** With all the talk of post quantum security, I really think people are sleeping on this one. It could be a critical backbone for post quantum secure chains to follow.
People could just sell BTC now and buy a quantum secure crypto like QRL rather than waiting and hoping that BTC gets upgraded before it's too late.
Why should i be invested since 2018? Anyway, my main point is to counter your claim that QRL is a waste of time. It hasn’t been, and it’s not. If you want to continue to be a pessimistic contrarian and shit on everyone’s choice of cryptocurrency with bogus claims, knock yourself out. We’ll see who wasted their time in the next few years. Have a good day friend.
Up much more than 300%? It’s not available on any tier 1 exchanges due to its difficultly to integrate. QRL is a unique, native Layer 1 blockchain. It uses the eXtended Merkle Signature Scheme (XMSS), which is fundamentally different from the Elliptic Curve cryptography used by almost every other chain. The PoS upgrade changes all that. It introduces an Ethereum-compatible API. Once fully live (with Testnet V2 having launched in Q1 2026), it will allow exchanges to treat QRL much more like an Ethereum-based chain, drastically lowering the technical barrier to entry. Once it’s on more common exchanges and able to integrate with other cryptos, it’ll jump. Im sorry my friend, but you don’t seem to know what you’re talking about
11 times - QRL (first quantumcurrency)
Yeah, that's a bit weird. QRL seems to have missed the last cycle run. You should be up much more for an altcoin that old. PoS never has been a good choice and in general it's more of a tech demo, so nothing you should put significant money in.
Im up 300% on my QRL. I expect more once it releases its PoS upgrade. Definitely not a waste of time so far, but you do you.
QRL was mentioned before Algerians: “A few blockchains have made progress in real-world deployment of PQC. In particular, the QRL [63, 64] launched in 2018 stands out as post-quantum from inception. Its original design was based on the stateful post-quantum signature scheme known as XMSS [241] and it is currently adding support for the stateless post-quantum signature scheme called CRYSTALS-Dilithium [242] and recently standardized by NIST under the name ML-DSA [243]. Other examples of post-quantum blockchains include Mochimo (MCM), which uses a variant of hash-based post-quantum Winternitz One-Time Signatures (WOTS) [244, 245], and the post-quantum privacy-preserving Abelian blockchain (ABEL), which makes extensive use of lattice-based PQC.”
**Securing Elliptic Curve Cryptocurrencies Against Quantum Vulnerabilities — Babbush et al. (Google Quantum AI / Ethereum Foundation / Stanford), March 2026** Core findings: * Shor's algorithm can break 256-bit ECDLP (the cryptographic basis of Bitcoin and Ethereum) On a superconducting architecture, this translates to fewer than 500,000 physical qubits and ~9 minutes of runtime. **Roughly a 20× improvement over prior estimates.** **Bitcoin vulnerabilities** * ~1.7M BTC in P2PK scripts exposes public keys directly; ~6.9M BTC total are currently at-rest vulnerable * P2TR (Taproot) reintroduced at-rest vulnerability; P2PKH/P2WPKH protect against at-rest attacks only if keys are never reused * **Proof-of-Work consensus is not meaningfully threatened** **Ethereum vulnerabilities** * All accounts that have sent a transaction expose their public key permanently (Account Vulnerability) * Admin keys controlling smart contracts, stablecoins (~$200B), and RWAs are at-rest vulnerable (Admin Vulnerability) * L2 rollups and bridges using zkSNARKs inherit cryptographic vulnerabilities (Code Vulnerability); ~15M ETH at risk * BLS12-381 validator signatures vulnerable; compromising 2/3 of validators would allow chain rewrite (Consensus Vulnerability) * KZG trusted setup for blob data availability is susceptible to a one-time on-setup attack (Data Availability Vulnerability) **Dormant assets problem** * ~2.3M BTC inactive for 5+ years cannot be migrated via software updates; likely includes Satoshi-era coins * Three community options: Do Nothing (quantum attackers eventually take them), Burn (protocol destroys them), Hourglass (rate-limits spending) **Migration to Post-Quantum Cryptography (PQC)** * PQC signatures (e.g. Falcon, ML-DSA) are 10–20× larger than ECDSA, creating bandwidth and consensus challenges for Bitcoin in particular Algorand (Falcon), QRL, Abelian, and Solana (experimental) are already deploying PQC **Migration must begin immediately; the authors estimate the window is still open but narrowing fast** *The quantum threat to cryptocurrency is closer than commonly assumed, affects active transactions (not only dormant holdings), and requires urgent PQC migration across all major blockchains.*
It’s in the paper they just published: https://quantumai.google/static/site-assets/downloads/cryptocurrency-whitepaper.pdf Ctrl+F “QRL”
Quantum Resistant Ledger ($QRL) was mentioned in the Google paper at least six times. For sure my favorite pure-QR play cooking. Recommended reading for anyone interested: [https://www.theqrl.org/blog/qrl-2.0-building-the-bridge-to-the-next-era/](https://www.theqrl.org/blog/qrl-2.0-building-the-bridge-to-the-next-era/) [https://www.theqrl.org/blog/google-just-set-a-2029-deadline-bitcoin-and-ethereum-arent-ready/](https://www.theqrl.org/blog/google-just-set-a-2029-deadline-bitcoin-and-ethereum-arent-ready/)
QRL but cant buy large amounts because of low liquidity/marketcap
QRL and similar coins are focusing on real long-term security—definitely worth watching 💪
QRL and other quantum resistant adjacent coins are quietly building up momentum rn.
$QRL. It's built entirely on NIST-standardized post-quantum cryptography, already running in production. It also provides financial-grade digital signatures and audit trails that remain secure even when quantum computers break today’s encryption. Great potential IMO.
That’s why I’m invested in QRL, and buy ETH and BTC on downturns like this. People be greedy. It’ll swing back up eventually, im literally betting money on it
I think Zcash's private transactions are still vulnerable to quantum-enabled attacks, so I'm not sure why it's listed. Why didn't you mention QRL? It's the biggest quantum-resistant blockchain.
Seven years are an estimation of the whole social-technical process of migration from preparing and discussing the concept until full integration of all users on the final product, like with SegWit and Taproot. Going offline during that process is nearly impossible, though. The 6 million figure includes those that have outgoing transaction (about 4 million), but are not S2PK. Most of these could probably move easily. I wouldn't expect a possible quantum attack this century, but it's always better to be safe than sorry. If QRL can provide a good experiment that can be integrated into Bitcoin's code, that's a good thing!
More like 2 million in total, if really nobody has got the key anymore. QRL doesn't solve the problem of what happens with these, so it is not a viable alternative. It could work as a case study of how to implement something comparable in Bitcoin (as with nearly all development in altcoins). Who estimates these times? A soft fork doesn't cause downtime. Who would endorse a protocol with 140mH/s. It's clearly a case study/experiment for Bitcoin core updates.
There are 6.2M BTC vulnerable in early legacy P2PK outputs and exposed public keys. For these vulnerable outputs, the choices really is only whether allow them to be stolen or freeze them. Satoshi alone has 1 Million BTC where the key is already revealed. Who in their right mind wants to endorse a protocol that freezes coins, or allows them to be stolen and leave the original owner? This is your future of finance? Downtime is estimated at over a year and migration taking up to 7 years. Sorry but no. You have to be quantum secure from genesis like QRL. Bitcoin is a dead man walking.
Buy the QRL dip. Low volume because of the overall lull in the crypto markets and one whale seller pushed it deep into oversold territory. Plus proof of staking is coming within the next 6 months which should also increase price.
QRL has been around for 8 years and standing strong in the midst of the quantum threat. Peter Thiele just got out of ethereum because of quantum threats, Kevin O'Leary recently said institutions should avoid crypto because of vulnerabilities to quantum computers. QRL is the only fully-audited, NIST guideline-following cryptocurrency, and that's why I'm loading up on it this most recent dip.
Even a quick ChatGPT will tell you Algorand is not Quantum Resistant. You have to be quantum secure from genesis or you run into all kinds of problems. 'Algorand’s CTO has publicly stated that while history protection is done, **accounts and consensus are still vulnerable** and need quantum-safe upgrades — estimating they are roughly *one-third* of the way to full quantum security.' There are tons of blockchains coming out claiming they are Quantum Resistant almost none of them are. QRL has been the leader in this space since 2018. Lockheed Martin even filed a patent using QRL for secure communications.
No I'm not part of the QRL Team. Just a guy interested in computers and blockchain.
They either have to freeze/burns coins, or allow them to be hacked/harvested by a Quantum Computer. Those are the only two choices. "QRL has had post-quantum security since 2018. No migration, no downgrade, no governance fight. Why store generational wealth on a foundation with a known expiration date and a painful fix when QRL already solved this eight years ago? - Alami

QRL has the blockchain encryption technology in place to be the long term secure digital fiat. Without quantum security already baked in, you’re just hoping that what you’re holding isn’t a gamble. QRL will be around for a long time.
Been in QRL since the beginning of last year. It's done fairly well for me. That is not an indication of future trends. Actually bought it because it was pretty stable for most of its history and figured the dip was coming, so when the moon rocket petered out I sold everything else and bought it, thinking I could at least protect my "money" from fiat and the upcoming bitcoin drop (4 year cycle thinking). Ended up 4x instead.
You might have heard about it already, but in the near future everyone will be talking about Quantum Computers breaking encryption, and when they do that quantum resistant cryptocurrency will gain a lot of attention regardless of anyone's thoughts on the matter, which will 100% result in wild price increases. The first and the leader in actual day 1 quantum resistance is QRL and it is integrating smart contract support in the near future as it is nearing audit and release (project ZOND)
I genuinely don't understand why more people aren't just buying QRL right now. It's so cheap relative to where it could be if it were more mainstream. The OG quantum resistant coin, without any vulnerability to quantum attacks. Used in a patent by Lockheed martin, around for 8 years...
QRL is poised to go higher. They are one of the best known quantum resistant coins, and as the narrative catches on, I'd expect a quick 10x
Quantum resistance, quantum resistance, quantum resistance. If you don't have a plan, investors with real capital are going to be uninterested. r/QRL is basically the only pure play in the market right now.
Stay ahead of the curve, rotate some into Quantum Resistant Ledger ($QRL)
During one of the worst days in crypto, $QRL +8%. Worth taking a closer look.
Absolutely, QRL is the only real post quantum safe haven with a PQ resistant first block track record since 2016.
QRL is more of a long-dated hedge than a near-term adoption play Until quantum becomes a clear and present threat, most attention stays on usability, infrastructure, and real-world integration If quantum suddenly becomes practical, projects already thinking about upgrade paths and governance will matter more than who was first Being adaptable often beats being early in crypto
I see. But that would be pure gambling. There are few other QR (or pseudo-QR, or fake-QR) coins and their mcap is small (as you wanted), but they were all dying (some had even -95% losses). Only QR coin that is successful is QRL. So, if you have been rekt too many times already, maybe you should start being more careful and not looking for wildfires. Good luck anyway :)
Lol, $200m is too high? QRL's martkecap is still 85x less than DOGE, which is a memecoin. 250x less than Solana. 1274x less than Ethereum. And 7225x less than Bitcoin.
Alright your call mate. I would seriously not fade $QRL.
It's too high already mcap wise. I need to do something different and DCA on this project. It's under $10m mcap. $QRL is 20x that.
Interesting, I haven’t heard of that one. I see it’s testnet only right now, so I’ll have to run it by some people who know more than myself. If you’re into post-quantum crypto, $QRL is a mandatory asset imo. It’s the only one I have rn as all of the others have yet to fully convince me they’re worth the time, and so far that’s been the best play returns wise, too.
I sold all my other crypto and full ported to QRL last July. Saved my ass, I’m up big since then and planning to hold. Extremely solid project, I’m lucky to have gotten in when I did <$1, but I actually just made my biggest purchase since initial position at $2.25 last week. Stop by the Discord if you want to learn a lot more: https://theqrl.org/discord The community is very intelligent, very informed, and very helpful. Top tier shit all around this project really. Very much looking forward to when the testnet for QRL 2.0 updates soon: https://www.theqrl.org/blog/qrl-2.0-building-the-bridge-to-the-next-era/
You mean QRL? Even your "Squirrel" in nick suggests connection to QRL community 👀
It’s the only coin that won’t easily be seized by bad actors and foreign institutions via quantum computing. If you want something long term safe over the next century. QRL is the only option. Nobody will be “leaving their kids” Bitcoin or any other ERC-20 token as that blockchain technology will easily be exploited and broken down within the next decade or two.
QRL +400% past year. Easy choice.
No guarantee but QRL has the highest potential to meet your goal and much more.
$QRL went 5x after BlackRock flagged quantum risk to crypto in May 2025. This is just a start.
QRL value will grow x5-x10 within a year because it will be listed on leading exchanges and will implement smart contracts with POS consensus.
QRL is a rock, it stays as it was.
How stupid do you think it is to invest in QANX or QRL?
That’s good then. I’m not sure what losses I’ll be capitulating as I only have QRL at a very low price at the moment.
Im long QRL and even im surprised at how resilient it’s been during this sell off. A solid base behind it for sure. Reminds me of BTC before it really took off.
Then why are they down over -50% in the last year while QRL, the market-leader in probably quantum-resistant cryptocurrency is up +600% ? Hint: it’s because they didn’t.
It's interesting how QRL has grown significantly after BlackRock flagged quantum risk to Bitcoin (May 2025).

/r/QRL Quantum Resistant Ledger Thank me later or remember when you faded this tip, your choice.
There is QRL (Quantum Resistant Ledger) blockchain which is built on the NIST standardized post-quantum cryptography since their launch in 2018. Externally audited, open source, decentralized and starting to gain popularity this last year. Also there is big upgrade coming this year that will bring smart contracts and proof of stake consensus. I recommend looking into it. They basically solved the problem 8 years ago, so there is no risk for QRL. And it's important to be quantum resistant since the first block, because all the other projects (like BTC, ETH,...) will have huge problems with migration of the current vulnerable coins/tokens/smart contracts/... as that requires manual action from every single user. If Q-day happens before 2030 (some estimations point even to year 2028) then I don't think there is any chance for existing chains to fully upgrade AND migrate their coins to be quantum safe.
No it is really not. First there are other chains that use PQC and more coming out everyday. This is not a moat my dude. Can you DeFi on it? Does it have any use other than Store of Value? QRL is cool but please lets not oversell reality.
Why the hell would you think QRL is a scam? It's been around 8 years, audited, used for patents by Lockheed Martin, never rugged, etc etc If you dont like altcoins that's fine but appreciation is warranted for legitimate projects in an ocean of actual scams
Anyone who seriously and responsibly looks into the topic knows that QRL is the only real choice when it comes to quantum-secure crypto. And the price action speaks for itself.
One concrete data point that often gets missed in these discussions is real-world validation. Lockheed Martin explicitly chose QRL in a quantum-secure communications patent (US20240048369A1). The patent references the QRL blockchain for encryption, key distribution, and secure messaging in a defense-sector context. That matters because this isn’t a whitepaper claim or a future roadmap — it’s a U.S. defense contractor selecting an already-deployed, quantum-resistant blockchain architecture for a real security use case. Most chains are still debating how they might migrate someday. QRL was designed around post-quantum assumptions from genesis, which completely sidesteps many of the coordination and hard-fork risks described in this post. It doesn’t mean quantum attacks are imminent — but it does show which architectures are being taken seriously when the threat model is treated as non-theoretical. That distinction feels increasingly important as migration timelines compress.
QRL is quantum secure from the first block. Also, Lockheed Martin (US defense contractor) has a patient utilizing the block chain for secure data transmission, showing real world use case https://patents.google.com/patent/US20240048369A1/en
Define “crypto scam”, and explain why QRL fits that description.
QRL is not pioneer. MCM running mainnet since June 25 2018 according public available information.
All these Quantum Computing scare monger posts seem always to be from people like the OP who fell for are are shilling crypto scams like QRL. See the OP's post history. 25 YEARS ago, **a 7-qubit quantum computer factored the number 15** and it was supposed to be a threat to breaking encryption algorithms > IBM researchers make another advance in quantum computing, demonstrating "Shor's Algorithm," which can break large encryption codes https://www.wired.com/2001/12/big-blue-takes-quantum-step **(2001)** 25 YEARS later, **1,000+ qubit quantum computers still aren't able to factor the number 21** because it's still too demanding for the hardware > Why haven't quantum computers factored 21 yet? https://algassert.com/post/2500 - **21** - The number that quantum computers still cannot factor with 1,000+ qubit hardware - **115792089237316195423570985008687907852837564279074904382605163141518161494336** - the range of private keys is between 1 and this number which is more atoms that exist in the known universe that dummies think that quantum computers will be able to guess > muh but Quantum Computers are getting exponentially more powerful It is estimated that millions of qubits are required to break ECDSA. But reality is that Quantum computers get exponentially nosier the more qubits they have. That's why a 7-qubit one in 2001 could factor the number 15 but 1,000+-qubit ones in 2026 cannot factor the number 15. **1,000,000+ qubit quantum computers will be exponentially more useless than the 1,000+ qubit quantum computers today.**
CKB is not a pioneer in this area. QRL is. The Quantum Resistant Ledger (QRL) has been running a public mainnet since June 26, 2018, operating for over seven years using post-quantum cryptography. By comparison, the Nervos CKB mainnet launched in November 2019.
Rekeying on Algorand is a migration mechanism, not a magic quantum shield. Rekeying enables migration, not quantum-safe accounts by default like QRL. Until a post-quantum signature scheme is actually used for account authorization, the account remains quantum-vulnerable. Algorand users still face migration pain that every other blockchain that is not quantum secure from genesis will have to go through.
