🚨 $QNT IS MOVING LIKE IT HAS SOMETHING TO PROVE 😂🔥 QNT just printed a $357 intraday high while trading volume crossed $1.5B. 👀 The crazy part? Its current price is still far below its $428 ATH. After a move this violent, #QNT #quantum #Crypto #BinanceSquare
the real question is: Can QNT reclaim its ATH? 🟢

Bitcoin ($BTC )’s quantum‑risk roadmap took three concrete steps this week.

A cost breakthrough slashes the price tag of post‑quantum cryptographic tools, opening the door for broader network upgrades.

At the same time, a new privacy design adds hidden layers to transaction data, raising the bar for any quantum decryption effort. Finally, a custody playbook spells out how custodians can shift to quantum‑resistant keys without disrupting service. These moves turn theoretical worries into actionable logistics. Which of these three advances—lower costs, stronger privacy, or clear custody guidance—offers the most immediate safeguard for Bitcoin?

6.9 million BTC (~$586B) sits in addresses EU regulators say a quantum computer could crack -- possibly before the tech is even commercially useful for anything else.

That's roughly a third of all circulating Bitcoin.

The news: The EU's three financial supervisory authorities (EBA, ESMA, EIOPA -- collectively "the ESAs") published their Autumn 2026 Risk Update on Sept 23, warning that advanced quantum computers could break the elliptic-curve cryptography securing blockchains "earlier than any viable commercial application" for the tech. The specific risk: legacy or reused Bitcoin addresses where the public key is already exposed on-chain, making them uniquely vulnerable to a "harvest now, decrypt later" attack -- adversaries collecting exposed public keys today, then decrypting them once a powerful enough quantum machine exists. The European Commission is urging member states to start post-quantum migration by end-2026; Ethereum has set a Dec 2029 deadline for its own quantum-resistant upgrade. Bitcoin has no agreed migration path yet -- proposals exist (BIP-360/361) but remain contested.

The catch: this is a risk timeline, not an imminent event -- no quantum computer today can actually break this cryptography, and estimates for when one might vary widely across the field. The real news is regulators formally flagging it as a systemic risk worth planning for now, not a countdown clock.

Our read: the interesting tension here isn't the science, it's the governance problem -- fixing this on Bitcoin requires networkwide consensus and moving billions in exposed coins, which is a coordination challenge with no clean precedent.

Does a formal EU regulator warning change your urgency on this, or does "quantum threat" still feel too far off to plan around?

Not financial advice. DYOR.

Quantum Threat: EU Sounds the Alarm
EU financial regulators have warned that quantum computing threatens blockchain encryption, and the issue of old addresses with public keys has become more urgent. At the same time, a week of working with AI coding lowered the estimated cost of a Bitcoin quantum-resistant transaction from $320 to $66. The topic of the year.

⚔️🛡️💸 QUANTUM ATTACK ON ₿ITCOIN BECOMES 86% “CHEAPER” IN JUST 2 MONTHS🤺

The race between blockchain and quantum computing has just gained a new alert.
An open challenge with more than 100 researchers and AI agents managed to reduce by approximately 86% a space-time cost metric of an essential circuit for a potential quantum attack on the cryptography used by Bitcoin and Ethereum.

The new circuit for the secp256k1 curve uses about:
⚛️ 1,151 logical qubits
⚙️ 1.30 million Toffoli gates
The benchmark score dropped from approximately:
10.75 BILLION → 1.496 BILLION
in less than two months.

🔥 Why Does This Matter?
A fault-tolerant quantum computer could, in theory, use Shor’s algorithm to recover a private key from an exposed public key.
According to an estimate from Coinbase’s quantum advisory board cited by the report, about 7 million BTC are currently in addresses whose public keys are already visible, including older P2PK-type wallets.

⚠️ BUT THIS DOESN’T MEAN BITCOIN CAN BE BROKEN TODAY

The researchers themselves stress that optimizing the circuit does not create the quantum computer needed to run it. Current hardware remains far from a fault-tolerant machine capable of this attack.
The warning sign is the speed of progress: AI + human researchers are reducing the required resources more rapidly.
Ethereum has already set an aggressive goal to make its L1 resistant to quantum threats across execution, consensus, and data layers by December 2029.

🔥 Maybe the real race isn’t
“When will the quantum computer arrive?”
But:
“Bitcoin▸ $BTC ▸ Ethereum▸ $ETH ▸ will be ready when it arrives?”

👇 Is the quantum threat still far off, or does it already deserve top priority?

#Bitcoin❗ #Ethereum✅ #quantum

Researchers just cut the estimated quantum-computing cost to attack Bitcoin and Ethereum's encryption by more than 50% -- and no machine on Earth can actually do it yet.

The news: a collaborative effort (100+ contributors, including teams from the Ethereum Foundation, Theta Labs, and StarkWare) designed a new quantum circuit needing 1,151 logical qubits and about 1.3 million Toffoli gates to perform the core arithmetic step in breaking the elliptic-curve cryptography (secp256k1) that secures both Bitcoin and Ethereum private keys. The combined resource score came to roughly 1.5 billion -- more than 50% below the ~3 billion benchmark Google Quantum AI published in March, and an 86% drop from where an open research challenge started just two months ago.

The catch: today's quantum hardware has only ~1,000-1,200 physical qubits and logical-qubit counts in the tens or low hundreds -- nowhere close to running this. This is a benchmark for a theoretical future attack, not a live threat, and remediation (protocol upgrades, wallet migrations to quantum-resistant signatures) has years of runway to happen before hardware could plausibly catch up. Progress like this tends to come in irregular jumps, not a steady countdown clock.

Why it still matters: roughly 7 million BTC sit in addresses where the public key is already exposed on-chain -- those are the coins most at risk whenever "Q-Day" eventually arrives, and industry-wide migration to quantum-resistant wallets takes years to roll out even once the tech exists. Research like this is exactly what should be driving that migration timeline, not a sudden hardware breakthrough nobody saw coming.

Does a 50%+ cut in the theoretical attack cost change your view on how urgent quantum-resistant wallet migration actually is?

Not financial advice. DYOR.

Ethereum aims to become a quantum-resistant L1 by 2029!

The Ethereum Foundation is targeting December 2029 to bring the network into a state that can withstand quantum attacks on the execution, consensus, and data layers.

Among the 62 proposals for the Hegotá upgrade, two notable priorities are FOCIL to enhance censorship resistance and Frame Transactions to abstract accounts, while laying the groundwork for the post-quantum era.

Hegotá is not yet a “quantum-resistant” hard fork, but it will play an important role in tracking progress. The Ethereum Foundation even wants to prepare for “Q-Day” as early as 2030.

Ethereum’s quantum-resistance race has officially entered the long-term phase.

⚠️ Study: The cost of a quantum attack on BTC and ETH drops by more than 50%

A new study indicates that the estimated cost of carrying out a quantum computing attack targeting Bitcoin and Ethereum has fallen by more than 50%.

📌 This development does not mean there is currently an actual quantum attack, but it once again highlights the risks of quantum computing and the importance of developing encryption solutions capable of resisting these attacks.

#Bitcoin #Ethereum #crypto #Quantum

Quantum computing power cut in half, and the “quantum threat” bills for Bitcoin and Ethereum directly got a 50% discount. The Ethereum Foundation and some researchers at StarkWare used AI agents to run optimization, pushing down Google’s March benchmark costs by another 50%+. Don’t rush to call it doomsday—this instead suggests that quantum-resistance upgrades should be put on the agenda. Whoever gets deployed first will capture the next wave of the narrative.

$IONQ 🚀 Quantum Computing needs a new scoreboard.

IonQ just published a benchmarking framework that looks beyond simple qubit counts.

The framework evaluates quantum systems on 13 real-world benchmarks across:

🔹 Optimization
🔹 Quantum Chemistry
🔹 Machine Learning
🔹 Data Loading
🔹 Simulation
🔹 Foundational Algorithms

The key metrics? Solution Quality + Time-to-Solution (TTS) — measuring how quickly a system can actually produce a solution that meets a predefined quality threshold.

What makes this interesting is the focus on the full system stack, rather than isolated hardware specifications.

Even more important: IonQ says the benchmark code is publicly available for independent verification, while comparative results were independently validated by Kearney.

⚛️ The quantum race may eventually be less about “Who has the most qubits?”

…and more about:

“Who can solve useful problems fastest, accurately, and at scale?”

That shift could be huge for the future of quantum computing.

Quantum threats are trending again! This time, Bitcoin Magazine went straight for a “quantum special,” seriously digging into whether quantum computing can actually destroy Bitcoin.

In plain speech, it’s three points:

1️⃣ The day quantum computers really become mature, the first to be hit would be early old wallets—Satoshi’s original 1 million BTC would theoretically be the first to get exposed

2️⃣ Bitcoin’s network attack surface isn’t as wildly exposed as people imagine, but it does have weak spots

3️⃣ Quantum-resistant solutions have been under research, but the community has turned into a big debate, so reaching consensus isn’t that easy

How should you look at the market? This kind of quantum FUD shows up to make a splash every so often, and the “pits” it throws end up being gold mines in hindsight. In the short term, sentiment might get steered off course, but once the day comes when quantum can actually crack it, Big Block (BTC) would have already completed the quantum-resistant upgrade. Technical fear has never been able to kill BTC—in fact, every time it shows up, it becomes an opportunity to get in.

Don’t get scared out of your position—hold steady.

Ripple unveiled a four-stage plan to transition the XRP Ledger to quantum-resistant technology by 2028.

Quantum computing threats are no longer just a future narrative. Recently, major ecosystems like Stellar, ETH, and SUI are pushing for upgrades related to anti-quantum/quantum cryptography, prompting the market to start re-evaluating the 'security premium'.

Quantum $QUANTUM is currently priced around $0.00193. The key focus isn't on short-term trades but on whether the narrative evolves from a concept into a real infrastructure demand. If anti-quantum security becomes a standard upgrade for public chains, related assets might gain temporary attention.

However, this kind of theme can be very volatile, so it's crucial to closely monitor on-chain activity, liquidity, and the actual progress of projects to avoid just chasing trends.
