Starknet Weighs Becoming a Layer 1 for Quantum Safety
Starknet says it's "actively considering becoming an L1" so it can become the first fully quantum-resistant network, with a 2027 target. Ethereum's goal is end-2029. Starknet's STARK proofs already rely on hashes rather than elliptic curves, but its bridge and data layer still inherit Ethereum's cryptography. No decision yet: any change needs governance approval. $STRK $ETH

Europol just published a quantum warning for crypto, and the headline is not "Bitcoin is broken".

The report from Europol's European Cybercrime Centre, released Oct 7, makes a narrower and more useful point: the blockchain is not the weak spot. The keys are.

What it says:
- The hash functions that secure blockchain history and mining hold up far better against quantum attacks than the public-key cryptography that controls wallets.
- Once an address has sent funds, its public key sits on-chain. A future quantum computer could work backward from it to the private key.
- About 6.9M $BTC sit in addresses with exposed public keys, including early and long-dormant wallets. Glassnode's May estimate was 6.04M, roughly 30% of supply.
- Keys that are already exposed can't be fixed after the fact. The only protection is moving those funds before a capable machine exists.

And the reassuring part: those machines don't exist yet, and Europol didn't predict when they will. Its verdict is "proactive adaptation, rather than systemic collapse".

The hard part is the migration. Post-quantum signatures can be 10 to 120 times larger than Bitcoin's current ECDSA signatures, which means bigger transactions, higher fees and a long, political upgrade debate. And lost or forgotten coins, like many early wallets, will never be moved by anyone.

So the real question isn't if Bitcoin survives quantum. It's what happens to millions of coins nobody can move in time.

Should Bitcoin freeze vulnerable coins someday, or leave them to whoever cracks them first?

👻 SATOSHI-ERA WHALE AWAKENS AFTER 16 YEARS

A wallet dormant since 2010 just moved 100.02 BTC (~$8.2M) — Galaxy Research

According to Bankless founder David Hoffman: This may be prep for QUANTUM-RESISTANT security.

Coincidence?
→ Yesterday: Vitalik warned AI could break ECDSA faster than quantum
→ Today: 16-year-old BTC wallet moves

Old wallets have exposed public keys. If ECDSA breaks, they are first to be hacked. Smart OG's are migrating to new PQ-safe addresses NOW.

Is this a sell or a security upgrade?

🚨🔓💻 #quantum THREAT ALERT: Europol Warns #crypto Wallets Are the Ultimate Target for Next-Gen Decryption! 📉⚡🏛️

A major security warning has just shattered the tech landscape! Europol’s European Cybercrime Centre (EC3) has officially published a critical report identifying cryptocurrency wallets as the absolute primary point of exposure to future quantum computing threats! ⚠️💸🔐

This is not a drill for the blockchain industry—the transition to quantum-resistant security must begin immediately to prevent catastrophic breaches:

🔓🔑 Private Key Derivation: A sufficiently advanced quantum computer could utilize algorithms to work backward from an exposed public key and derive your private key, allowing unauthorized fund transfers without your consent! 😱💸

Permanent Data Risks:** Attackers are currently practicing "Harvest Now, Decrypt Later" (HNDL), storing current on-chain public data to crack it the second quantum hardware scales up! 📂⏳🕵️‍♂️

Vulnerable Supply:** Industry estimates reveal that over 6 Million Bitcoin (around 30% of circulating supply) are held in legacy or reused addresses with exposed public keys, creating a multi-billion-dollar risk vector! 📊⚠️🪙

⚙️⛓️ The Upgrade Dilemma: Migrating entire decentralized networks to post-quantum cryptography will cause massive signature sizes, potential block congestion, and requires complex community consensus! 🛠️🤯

The race between quantum codebreakers and blockchain developers has officially accelerated! Secure your infrastructure before Q-Day arrives! 🏁🌐💎

Your Bitcoin wallet math homework just got harder.

Washington just wound the "Q-Day" clock tighter: the White House 6B science package includes a DOE competition with up to $215M for quantum computing. Meanwhile Ethereum researcher Justin Drake warned AI could crack the math shielding crypto wallets sooner than expected — while Bitcoin Core developer Antoine Poinsot pushed back, calling the panic evidence-free.

Is your $BTC at risk tomorrow? No — but the clock is ticking. Zcash already aims to ship quantum-resistant payments by January.

Takeaway: the market has not priced quantum risk yet, but the smart builders are preparing for when, not if. Not financial advice.

Starknet is considering leaving its status as an Ethereum L2 to become a quantum-resistant L1 by 2027. The market didn’t wait for a vote: $STRK rose 57% in two days on Binance.

The timeline:

Oct. 7: Justin Drake (Ethereum Foundation) calls for preparations for “bunker mode,” as AI could threaten wallet signatures sooner than expected.

Oct. 8, 08:32 UTC: Starknet’s official account writes, “We are actively considering becoming an L1,” targeting 2027, in response to a question from Eli Ben-Sasson (StarkWare CEO). The 1-hour candle moves from $0.0492 to $0.0530.

Oct. 9, 17:00 UTC: price peaks at $0.07716, compared with $0.04907 at the close on Oct. 7. That’s the highest level since Jan. 22 ($0.0807).

According to Binance data, STRK perpetual open interest rises from $11.1M (Oct. 8, 07:00 UTC) to $31.0M (Oct. 9, 18:00 UTC), while STRK/USDT spot volume reaches $53.4M on Friday, versus a 20-day average of around $10.4M. Funding is nearly neutral (+0.0044%). CoinDesk, citing CoinGlass data, notes that futures volume is around 5 times spot volume.

Ben-Sasson’s argument: Ethereum aims to make its L1 quantum-resistant by the end of 2029, Bitcoin has made no commitment, and Starknet could do it in 2027.

My take: the price is reflecting a narrative, not a decision. There’s no formal technical plan or governance vote at this stage. Open interest up about 2.8x with flat funding looks like longs entering, not a short squeeze.

Two paths:
Holding above $0.0625 (the Oct. 8 high) preserves the bullish structure, with $0.0807 in sight.
A move back below that level would open the door to a return to $0.055–$0.056, where the Oct. 9 rally began.

For an L2, leaving Ethereum to move faster on post-quantum security: a real advantage, or the end of the argument for inherited security from $ETH ?

🚨 $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.
