Could be. I’m not pitching a trade, I’m pointing at a cryptographic deadline. If your coins live behind ECDSA, the question isn’t whether QRL has value, it’s what your chain’s plan is for the day exposed public keys stop being safe. “Quantum-safe chains are worthless” and “my ECDSA keys are fine forever” can’t both be true. Happy to be wrong, my keys aren’t the ones on the clock.
Excellent post! It really seems that ECDSA may be broken sooner than expected. It’s interesting that Trail of Bits developed this circuit improvement while simultaneously auditing QRL. They are clearly keeping a close eye on advances in quantum computing and helping ensure that quantum-safe crypto is built with security as a top priority.
Fair correction. To be precise: ML-DSA-87 targets NIST security category 5, which is the top of NIST's 1 through 5 scale, so it does sit at the highest tier. What it isn't is the only scheme up there. Falcon-1024 and SPHINCS+/SLH-DSA at their 256-bit parameter sets also land at category 5, so ML-DSA-87 shares the top tier rather than standing alone above everything. Within ML-DSA's own three options it's the strongest (ML-DSA-44 = level 2, ML-DSA-65 = level 3, ML-DSA-87 = level 5). So "highest tier" is accurate, "uniquely highest" would not be. I should've said "NIST's top security category (Level 5)" to avoid implying it's the single strongest. Good catch. QRL signs on the consensus layer with ML-DSA-87 (category 5), and is adding Falcon-1024 and ML-KEM-1024 on the networking layer, so it's using more than one category-5 primitive rather than betting everything on one. see [https://www.theqrl.org/weekly/](https://www.theqrl.org/weekly/)
QRL (quantum resistant ledger) peut être un bon parie , ils vont passé en preuve d'enjeu bientôt.
Wasn‘t there a proper Audit? I see currently at QRL for example, they do months of Audit with two external Auditors before mainnet
Crazy how few people know about QRL. It is the best, most secure PQ chain Ethereum Virtual Machine compatible plus fixed supply at 105 million. Crypto agile means they can keep improving. Only EVM chain so far that has demonstrated Ethereum level performance. I wouldn’t put my money counting on every ETH holder to act, act thoroughly (migrate everything), and in perfect coordination with others. Just move your project over to QRL. Why not?
Lockheed Martin adopting leading quantum-safe blockchain tech is pretty hard to ignore. QRL’s availability is still limited so a great opportunity for early birds before Tier 1 listing.
I agree. IMO, $QRL is by far the most legit quantum-safe project.
That is why QRL 2.0 is crypto agile, it is engineered with a three byte descriptor in its address, when a new cryptography comes out, the new descriptor gets defined, functionality gets defined, the chain will just keep working. Not need to migrate. Best engineered chain for the new era. Its L1 performance is on par with Ethereum despite 30-70x bigger signature, at Level 5 max NIST security, a feat unmatched by anything out there.
Post is by: schrodingersbadger and the url/text [ ](https://goo.gl/GP6ppk)is: /r/QRL/comments/1tuzybo/the_lockheed_martin_patent_related_to_the_quantum/  The document describes a secure communications architecture based on quantum-resistant cryptography and the use of a distributed ledger for the management and validation of cryptographic information. One of the pages in the patent contains the official QRL (Quantum Resistant Ledger) logo, making it clear that the reference is to the specific project and not merely to the abstract concept of a quantum-resistant ledger.  The patent demonstrates that the technology and concepts associated with the project were considered relevant enough to be incorporated into a patent granted to one of the world's largest aerospace and defense companies. As the transition toward post-quantum cryptographic systems becomes increasingly important, it is interesting to observe real-world cases in which major organizations are exploring architectures designed for long-term security and resilience against future quantum threats. This is a development that deserves attention. *I am a bot, and this action was performed automatically.

Definitely Quantum Resistant Ledger (QRL). Watch for QRL 2.0 mainnet date, likely this year.
There are claims of an ongoing effort to suppress QRL’s ranking on CoinMarketCap. Some believe Binance may be involved, with a Tier-1 exchange listing being seen as the solution. I won’t say anything more those who are interested can look into the matter themselves and DYOR
QRL. If you want to ride the next wave and keep your finances secure as quantum computers advance, there is no other choice.
Funny enough, I'm not a QRL guy.
The QRL army has arrived! Respek to you all. Fight for dem bags - we have all been there.
For me personally there is no Scam/Rugpull/criminal behavior which I see in QRL project. Other Quantum related projects Act here totally different imho… What QRL has as plus -official, swiss based, foundation in backhround -wide dev team - not only Single people -good compliance - they run an Audit on the current QRL 2.0 project with two independent Auditors -Active Community - see Discord Community -coinmetrics are developing well in the last months -Tech-stake recognized by Major „independent“ players (See mentioning in Last Google paper)
QRL will be long term secure. It has no sister tokens running on ERC-20 or sister platforms.
Governance of Mochimo project is more than critical - one crazy guy dominating the whole project - sold all of mine just recently. I hold QRL (Major one) and ABEL (last year the third serious project)
By “a quantum-safe chain,” I meant adopting QRL, PQ EVM allowing you to replicate your project on a quantum safe L1. Migration will mostly fail with the much larger signature size being one of the reasons. What is remarkable about QRL 2.0 is that its base layer performance is on par with Ethereum despite using the most secure (largest and most difficult to keep fast) Level 5 NIST PQ signature, ML-DSA-87.
You make it seem like upgrading to PQC can just be turned on like a switch. While some chains have an easier migration path than others, a lot depends on the CRQC timeline. If Qday hits before 2030, expect absolute chaos across crypto. QRL avoids the quantum uncertainty altogether. And as quantum hardware advances, that secure foundation will have serious appeal for builders and investors a like.
This is the very first line of the section regarding “Post-Quantum Blockchains”. \- “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.”
Negative. Their names were mentioned more times and the article talked about them for longer because they had to explain the nightmare that it is to migrate a whole vulnerable chain to PQ. When they mentioned QRL it was pretty much “QRL already is PQ resistant”, there was no explaining how they were going to do it. It is already done.
Yes. They were mentioned more often because they are not quantum resistant yet, so the paper had to explain how they are scrambling to get up to speed. QRL was mentioned first and they didn’t have to explain how they are going to transition to PQ because it already is.
And other chains were mentions far more often than QRL in the paper.
>Give me an example of one of these so called “more credible” chains that will be quantum resistant “soon”. Algorand Their chief scientific officer is Chris Peikert, the guy that created FALCON a NIST recommended PQC signature scheme. Accounts can use PQC signing keys now but you pay more fees as more blockspace is needed. They haven't addressed the VRF yet because the risk is small and the cost is high in performance. To attack the VRF would need a quantum computer attacking it in under 3 seconds, which will be impossible long after large qbit quantum computers exist as they will be unstable when they first exist. QRL is a one trick pony Algorand is the real thing.
Oh shit, someone at Google _mentioned_ QRL in the background section of their paper? To the moon!
QANX (QANplatform): QANplatform launched a quantum-resistant L1 using lattice-based cryptography back in 2022, but it’s a hybrid that still leans on non-PQ components and has nowhere near QRL’s eight-year, PQ-from-genesis mainnet track record. Cellframe: Cellframe’s post-quantum signatures are an opt-in feature, not the default, so the bulk of activity still runs on classical ECDSA-style curves, meaning most of what’s on it is no more quantum-safe than Bitcoin.
Have you taken a closer look to Mochimo and QRL?
“Frame is launching an L1 PQ chain”? Frame is a March press release, not a chain. The Crypto Company, an OTC microcap with a \~$8M market cap and a stock down 85% in six months, bought the IP and says it “intends to launch this year” on a $2M development budget. No mainnet, no track record, no audit. “Post-quantum security” is a single feature bullet with zero detail; they don’t even name an algorithm. QRL has been live and post-quantum for eight years, independently audited, with a public testnet you can use right now. One is a running network. The other is a press release.
Ignore QRL at your own risk. Which other L1 has: 1. Eight years live as a public quantum-safe chain with near-perfect uptime. 2. Post-quantum security from the genesis block. Nothing to migrate, no keys ever exposed. 3. A live EVM-compatible post-quantum testnet you can build on today, not a 2029 promise. 4. Proven crypto-agility: upgraded its signatures to NIST’s top level across the whole stack in \~2 weeks, no hard fork. 5. A clean post-quantum crypto audit, with the protocol audit run by Trail of Bits. 6. Throughput in Ethereum’s range despite signatures many times larger than ECDSA. Name one chain that checks half these boxes. “It’s small” isn’t a rebuttal to the tech, it’s the entry price.
Your post makes no sense. You say “The devil is in the details”, then you post the mention of QRL in the Google paper (that was written by team at Google Quantum AI, the Ethereum Foundation, and other experts. Not by some random internet) which states that QRL uses only post quantum cryptography, as opposed to vulnerable cryptography such as ECC, and then ask “who cares”? LOL
The devil is always in the details. Google intern writing a paper, umm "Googles" and sees QRL amongst others. "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 \[62, 67\]." I mean, who cares? I know you want to pump your bags and you might well succeed. I for one hope that not too many people get trapped, and it dies quietly on MEXC or whatever other shitcoin peddling site still lists it.
QRL is the most laughable retail trap in crypto. The only thing it has going for it is it's name. It will probably sucker a few more unfortunates in over the next few years. Other, more credible chains, will soon upgrade to be resistant to quantum computing and "QRL" will disappear like a fart in the wind.
QRL! marketing is not great on there end but the project is solid, been around since 2018 I think, big upgrades coming this year with smart contracts and trail of bits doing there audit, a challenge to buy but they are vectoring towards tier one exchanges, and price is solid now and bottomed out it seems like
I can see you are an intelligent/well informed individual. Quantum computing is ABSOLUTELY a threat. I own a decent amount of BTC. That being said, I am not sure Bitcoin will be able to make the network quantum safe in time. When began asking the same question as you, I ran into another crypto currency called Quantum Resistant Ledger (QRL). I have since been DCAing into QRL. One thing that gave it a lot of credibility in my book, was the fact that Lockheed Martin (the defense contractor) has a patent that uses QRL blockchain for quantum resistant communications. QRL was also mentioned in the Google paper on quantum computing and blockchains. Don’t take my word for it, ask an AI about it and do your own research.
Check out the quantum-resistant version of Bitcoin QRL / Quantum Resistant Ledger
BTC and QRL and nothing else
Only $QRL (Quantum Resistant Ledger). All your altcoins (including Bitcoin) can be broken by sufficiently powerful quantum computer. If you want to hold something safely for more than few years, it's QRL.
BIP360 is only the first step forward, not the complete solution. And the hedge using quantum secure coins - is it QRL?
It doesn’t need to be that smart to understand quantum threat or the appeal of QRL at this time.
Like I said above about how looking for friends in this space will just lead you towards more shilling and scams. Take this post for example. You're looking for a community to talk crypto and this random dude shills his QRL blockchain project. It's just another project they are shilling lol. You are too innocent if you think otherwise. The guy literally just shilled you a dead "quantum resistance blockchain" project from 2018 lol.
Go to the Discord server for the QRL community. Find it on TheQRL dot org, honestly the best blockchain and best community.

Yes, the patent mentions QRL directly and even includes the logo. Since QRL is an open-source project released under the MIT License, the code can generally be used freely within the terms of that license.
That is QRL isn’t it? The most established quantum resistant ledger that no one knows about. QRL 2.0, hopefully moving to mainnet Q3 or Q4, is going to be a game-changer - EVM compatible, performance on par with Ethereum, crypto agile with its 3 byte descriptor in the address, among other things.
From what I can tell, the patent appears to reference Quantum Resistant Ledger (QRL), an open-source project focused on post-quantum cryptography. The patent text specifically mentions “QRL technology,” and the filing also includes the project’s logo in the context of secure communications architecture. That doesn’t necessarily mean Lockheed Martin is using the public QRL blockchain, but it’s interesting to see quantum-resistant ledger concepts appearing in defense-related research and patents. It could also suggest growing interest in post-quantum secure blockchain architectures more broadly.
It is not catastrophic like that though. Major companies are all working on it. We crypto people just need to face it too. There are quantum safe chains out there. Look up QRL 2.0.
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

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.
