Official QRL Show Live | Live AMA with Kaushal (Lead Blockchain Developer) x.com/i/broadcasts/1nxnRYlzW…

Starting my journey into zero-knowledge… with zero knowledge. #PostQuantum #Blockchain #Crypto

As the quantum threat to current cryptography becomes harder to ignore, exchanges may want to start evaluating projects already built for that future. Quantum Resistant Ledger ( $QRL ) is a live Layer 1 using hash-based signatures since 2018 - not a planned upgrade. Referenced in Google Quantum AI research: quantumai.google/static/site… And in a Lockheed Martin patent: patents.google.com/patent/US… @upbitglobal - worth a closer look. #PostQuantum #Blockchain #Crypto

Post-quantum cryptography is progressing, but we're not "done." We have: • Dilithium, Falcon, XMSS, SPHINCS (signatures) • Kyber (KEMs) But we still lack: • Efficient ZK • Threshold & multi-sig (mature) • BLS-like aggregation The hard part is just beginning. #PostQuantum #Crypto #Blockchain

Everyone's chasing the next $1 billion coin… but ignoring the one problem that could break them all: quantum risk. Quantum Resistant Ledger ( $QRL ) solved this in 2018 - live mainnet, not a roadmap. Referenced by Google Quantum AI: quantumai.google/static/site… And in a Lockheed Martin patent: patents.google.com/patent/US… Most people haven't noticed yet. That's how early it still is. @Bybit_Official @benbybit - are you watching? #PostQuantum #Crypto #Blockchain

Quantum risk is approaching, and hardware wallets need to be ready. Future devices should be designed to easily support post-quantum schemes like ML-DSA-87 and SPHINCS - without extreme optimization tradeoffs. Building PQ-ready hardware today will define crypto security tomorrow. @Ledger - hope this is already part of the roadmap. 🔐⚛️ #PostQuantum #Crypto #Blockchain

Personally, I don’t think quantum is a "tomorrow problem". But it’s also not a "ignore until it hits" problem. It’s one of those things where early preparation is the only realistic option.

Standards are already coming out of NIST. And some projects didn’t wait for the problem to become urgent. Quantum Resistant Ledger ( $QRL ) is one example - built around XMSS from day one.

So "taking it seriously" doesn’t mean hype or fear. It means: • Designing for crypto agility • Thinking about migration paths early • Reducing unnecessary key exposure Basic engineering discipline.

There’s also the part people ignore: Public keys exposed today don’t disappear. They can be stored now and attacked later. Especially for chains where keys are already revealed.

Once large-scale quantum machines exist, algorithms like Shor’s algorithm won’t give you a warning period. Attackers need a short window. Defenders need years of coordination. That mismatch is the real risk.

Even today, most users still reuse addresses, don’t rotate keys, and delay upgrades. Expecting a smooth post-quantum migration across the entire ecosystem is… optimistic.

From building in this space, one thing is obvious: Upgrading anything in crypto is slow. Wallet migrations, user behavior, consensus changes… none of this happens overnight.

I see a lot of people dismiss quantum risk because “it’s not here yet”. That’s technically true. But crypto doesn’t break gradually - it breaks suddenly when assumptions fail.

Post-quantum security is becoming increasingly relevant for crypto infrastructure. Quantum Resistant Ledger ( $QRL ) is a live Layer 1 built on hash-based signatures (XMSS), not a future upgrade.
