quantumcomputers

I won’t pretend to deeply understand quantum physics, or quantum computing specifically, I don’t, but I grasp enough to know that the theory underlying it is sound.
For certain classes of parallelizeable computations, the physical properties of quantum computers’ qubits allow searching for correct answers in very large search spaces exponentially more efficiently than classical computers. We have proven mathematical algorithms for these faster computations for a number of different computational problems, and there are many more that don’t yet have proven algorithms. 
The question is whether it is practical to achieve from an engineering perspective, i.e. can we actually build machines that are efficient, reliable, and powerful enough to actually take advantage of quantum theory in a way that is useful at solving real problems? 
That’s why I went to the Quantum Bitcoin Summit at the Bitcoin Presidio in San Francisco. 
The small day and a half summit was attended by experts in both the quantum computing industry as well as Bitcoin developers. There were presentations on the current state of quantum computing, the specific risks to Bitcoin we would have to deal with after the development of a practical quantum computer, potential solutions we have to post-quantum cryptography, as well as debates over how to handle different aspects of the problem.

As quantum computing advances, the security of traditional cryptographic systems faces a major threat. Quantum computers, with their immense processing power, could break widely used encryption methods like RSA and ECC, making current blockchain networks vulnerable. In response, the crypto industry is exploring post-quantum cryptography (PQC) to ensure security in a quantum-powered future.

Why Quantum Computing Threatens Crypto

Most blockchain networks rely on public-key cryptography to secure transactions and wallets. Shor’s algorithm, a quantum computing algorithm, can efficiently solve the complex mathematical problems that underpin these encryption methods. If large-scale quantum computers emerge, they could potentially crack private keys, leading to security breaches across blockchain networks.

Post-Quantum Cryptography: The Next Step

Post-quantum cryptography refers to cryptographic systems designed to withstand quantum attacks. Researchers and blockchain developers are actively exploring quantum-resistant cryptographic algorithms, many of which have been evaluated by the National Institute of Standards and Technology (NIST). Some promising techniques include:

Lattice-based cryptography – Uses complex mathematical structures that are resistant to quantum decryption.

Hash-based cryptography – Secure digital signatures that remain safe from quantum attacks.

Multivariate polynomial cryptography – Encryption based on solving polynomial equations, considered quantum-resistant.

Top Crypto Projects Focused on Quantum Resistance

Several blockchain projects are proactively integrating post-quantum security measures to future-proof their networks. Here are some key players:

1. QANplatform (QANX)

QANplatform is a quantum-resistant Layer-1 blockchain that uses lattice-based cryptography to secure smart contracts and transactions. It aims to provide a quantum-proof foundation for developers and enterprises.

2. Algorand (ALGO)

Algorand is actively researching post-quantum security solutions. While not yet fully quantum-resistant, its team is exploring future upgrades to protect against quantum threats.

3. Quantum Resistant Ledger (QRL)

QRL is one of the first blockchain networks designed explicitly to resist quantum attacks. It employs XMSS (Extended Merkle Signature Scheme), a hash-based signature method deemed secure against quantum decryption.

4. IOTA (MIOTA)

IOTA, known for its Tangle technology, is developing quantum-resistant signatures to secure transactions, making it a strong contender for post-quantum security.

5. HyperCash (HC)

HyperCash is another blockchain network focusing on quantum-resistant cryptographic techniques to ensure long-term security.

The Road Ahead

While quantum computing is still in its early stages, preparing for its potential impact is crucial. Blockchain networks must adopt quantum-resistant cryptography to remain secure in the next era of computing. Investors and developers should watch for projects implementing post-quantum solutions, as they will likely play a vital role in the future of decentralized technology.

Final Thoughts

The post-quantum crypto landscape is still evolving, but proactive projects are paving the way for a secure blockchain future. As quantum computing advances, staying informed and investing in quantum-resistant blockchain projects could be a strategic move for long-term security and growth.

🔐 The future of Bitcoin and digital security might be under threat much earlier than many anticipated. Google has revealed that recent breakthroughs in quantum computing could significantly reduce the resources required to crack the encryption protecting crypto wallets and sensitive data.

⚠️ Quantum Leap: From 20 Million Qubits to Under One Million
Craig Gidney, a quantum researcher at Google, stated that factoring a 2048-bit RSA key — one of the core cryptographic standards — may no longer require 20 million qubits, as he estimated in 2019. Instead, it could now be achieved with fewer than one million qubits in under a week.
This leap is possible thanks to:

🔹 advanced quantum algorithms,

🔹 improved error correction techniques,

🔹 and denser qubit encoding that allows for more efficient operations.

⚡ Willow Chip Solves "10 Septillion-Year" Problem in 5 Minutes
In December 2024, Google unveiled its new quantum chip Willow, capable of solving a problem in five minutes that would take traditional supercomputers 10 septillion years. Critics quickly raised alarms, suggesting that such power could potentially rewrite the Bitcoin blockchain or even access dormant wallets, including those possibly linked to Satoshi Nakamoto.

🧠 What This Means for Crypto Security
Bitcoin uses elliptic curve cryptography, which is mathematically similar to RSA. If quantum computers can crack RSA faster than expected, Bitcoin's security timeline might have just shortened significantly.
Google warned that some state actors or tech rivals might already be collecting encrypted data now to decrypt later when quantum machines become viable.

🧪 Magical States and Quantum Efficiency
Google researchers also employed so-called T-states (magical quantum states) to boost computing power without increasing system load. This technique allows for more efficient operations, saving time and physical space.

🔎 Project 11: Quantum Bounty on Bitcoin Security
Meanwhile, Project 11, a quantum research group, has offered a $85,000 bounty to anyone who can break a simplified version of Bitcoin's encryption using a quantum computer. While the test targets short key lengths (1 to 25 bits), far below Bitcoin’s 256-bit standard, it helps assess how urgent the quantum threat really is.
The group argues that Shor’s algorithm, a key quantum technique, could eventually break Bitcoin’s elliptic curve encryption altogether.

📅 Timeline: Is 2030 Too Late?
The U.S. National Institute of Standards and Technology (NIST) recommends phasing out vulnerable systems starting in 2030. But Google’s findings suggest this timeline may be too conservative.
Tech giants are already making moves:

🔹 IBM aims to build a 100,000-qubit quantum computer by 2030

🔹 Quantinuum plans to deliver a quantum-secure system by 2029

🧩 Bottom Line: Bitcoin Is Safe… For Now — But the Clock Is Ticking
Google reassures that user digital assets are currently safe. However, the trajectory of quantum progress is undeniable. The crypto industry must start preparing now if it hopes to remain secure in the quantum age.

Bitcoin, a cryptocurrency, relies on cryptographic algorithms to ensure its security. However, the emergence of quantum computers poses potential threats to Bitcoin's security protocols. In this article, we'll explore the likelihood of quantum computers hacking Bitcoin and the future of cryptocurrencies.
Bitcoin's Security Protocols
The Bitcoin network uses SHA-256 hash function and Elliptic Curve Digital Signature Algorithm (ECDSA) to secure transactions. These algorithms are considered difficult to break for current classical computers.
Capabilities of Quantum Computers
Quantum computers operate using quantum bits (qubits) and can perform computations by leveraging quantum mechanical properties such as superposition and entanglement. This enables them to calculate multiple possibilities simultaneously, potentially solving certain problems much faster than classical computers.
Quantum Computers and Cryptography
Quantum computers, particularly through the use of Shor's Algorithm, could have superior abilities to factor large numbers into prime factors. This poses a threat to cryptographic algorithms like ECDSA, which rely on prime factors.
Bitcoin Network's Resilience to Quantum Attacks
Currently, it's too early to discuss the practical existence of a quantum computer. However, if such a computer is developed in the future, the Bitcoin network would need to update its security protocols. Transitioning to post-quantum cryptography could be a solution.

While quantum computers theoretically have the potential to hack Bitcoin, practical implementation of this technology is not yet available. Bitcoin and other cryptocurrencies continue to work towards enhancing their security against future threats.

Quantum computers are considered one of the most promising technologies of the future. They promise computing power far beyond that of classical computers. However, this revolution could also pose a threat to modern cryptography—and thus to systems like Bitcoin.
The critical question is: Can quantum computers break Bitcoin? And if so, will Bitcoin need an upgrade?
How Quantum Computers Threaten Cryptography
The security of modern cryptography relies on mathematical problems that are difficult for classical computers to solve. Bitcoin primarily uses two algorithms:
1. SHA-256 (for hash functions)
2. ECDSA (Elliptic Curve Digital Signature Algorithm, for digital signatures)
Quantum computers could specifically attack ECDSA using Shor’s Algorithm, which can break elliptic curve cryptography. In theory, this would allow an attacker to derive private keys from public addresses—a nightmare scenario for Bitcoin.
Does This Also Affect SHA-256?
Fortunately, SHA-256 (and similar hash functions) are only minimally vulnerable to quantum attacks. Grover’s Algorithm could theoretically cut search times in half, but even then, attacking Bitcoin mining or transaction hashes would be extremely resource-intensive.
Is Bitcoin Really at Risk?
The good news: Not anytime soon.
1. Quantum computers are not yet powerful enough
- Current quantum computers have only a few error-prone qubits.
1. Breaking ECDSA would require thousands of error-corrected qubits—something that is still years or decades away.
2. Bitcoin transactions are often "quantum-resistant"
- As long as Bitcoin addresses are used only once (as recommended), the risk is low.
- Only publicly known addresses (e.g., unused funds in old wallets) would be vulnerable.
3. The community can adapt
- If quantum computers become a real threat, Bitcoin can upgrade to quantum-resistant cryptography (e.g., Lamport signatures or lattice-based cryptography).
Will Bitcoin Need an Upgrade? Long-term: Yes.
Once quantum computers become practically viable, Bitcoin will need to update its signature algorithms. However, progress is slow enough that the community will have time to respond.
Possible Solutions:
- Post-quantum cryptography (e.g., XMSS, SPHINCS+)
- Schnorr signatures (already part of Bitcoin’s protocol, offering better scalability and serving as a foundation for quantum-resistant upgrades)
- Hybrid systems (combining ECDSA with quantum-resistant signatures)
Conclusion: Bitcoin is (Still) Safe
Quantum computers pose a potential threat, but not an immediate one. Bitcoin developers have time to prepare, and promising quantum-resistant solutions already exist.
Bitcoin won’t be cracked overnight—but the community must stay vigilant. Once quantum computing makes significant advances, an upgrade will be necessary. Until then, the network remains secure.

Is quantum computing threatening Bitcoin sooner than expected? On Wednesday, Microsoft unveiled its first quantum computing chip, dubbed “Majorana 1.” While the tech community has long speculated about Google’s next-generation quantum effort—often referred to as “Willow”—Microsoft’s announcement places renewed focus on the looming question: Can Bitcoin survive the accelerated push toward million-qubit machines?
Microsoft claims that Majorana 1 leverages a new topological core architecture designed to bring quantum computing out of the lab and into meaningful, real-world applications “in years, rather than in decades.” The chip’s unique design reportedly allows quantum systems to operate for longer periods and at more stable states than previous generations.

According to Microsoft CEO Satya Nadella, the company’s roadmap points to a one-million-qubit device by around 2027–2029—an ambition many in the field consider necessary for tackling “industrial-scale” computational tasks.
Is Bitcoin At Risk?
While most financial institutions rely on layered security systems, Bitcoin’s reliance on public-key cryptography has many wondering if it could be an easier target for quantum attacks. A Bitcoin-focused financial platform, River, sounded the alarm in a recent X thread, noting that “1 million qubits can potentially crack a BTC address.” They cautioned that “the Majorana 1 chip is far from that scale now, but could reach the 1 million mark by 2027-2029.”

River’s analysis also suggested that a device with 13 to 300 million qubits—once stabilized—could theoretically break a Bitcoin address within hours, potentially placing up to 5.9 million BTC at risk. Though today’s quantum computers are nowhere near that capacity, River stressed that Microsoft’s achievements shorten the overall timeline, meaning Bitcoin developers cannot afford complacency
“When run for several days to weeks, a 1-million qubit QC could potentially crack Bitcoin addresses via a long-range attack. […] More realistically, we’d need a QC with 13-300 million qubits to carry out a long-range attack in 1-8 hours. If achieved, this would put 5.9 million BTC at immediate risk. Remember that the best QCs today have only 1,000 qubits. Still, this breakthrough shortens the timeline to make Bitcoin quantum-resistant,” River writes.
Alexander Leishman, CEO of River, emphasizes in a post on X that BTC’s unique setup could expose it more directly to quantum threats compared to banks and other centralized entities. “Access to a public key equals access to the money,” he said, pointing out that traditional banking systems rely on a host of protective layers. Even if quantum hardware were to render HTTPS encryption obsolete, Leishman noted that hackers would still have to surmount additional firewalls, authentication protocols, and in-person security checks to breach a bank.
In contrast, once a Bitcoin public key has been revealed (as happens when BTC is sent from an address), a sufficiently powerful quantum computer might bypass the corresponding private key if it can run the right algorithm for enough time. Leishman admitted he is “skeptical it’s a near-term problem,” but emphasized that ignoring the quantum threat could be shortsighted.
“A quantum computer will not magically give you access to all of the money at Goldman Sachs. It WILL magically give you access to many billions of dollars worth of Bitcoin. Again, I don’t think this threat is viable any time soon but it’s important that we discuss the issue honestly”, he argues.
Prominent Bitcoin commentator Preston Pysh joined the discussion via X, asking if the community should “prioritize engineering quantum-resistant addresses” and pointing to BIP-360 (the proposed P2QRH framework). Pysh suggested that this proposal could potentially be enacted through a soft fork, a method that typically allows for backward compatibility while adding new features to the Bitcoin protocol.
Leishman agreed that securing Bitcoin against quantum attacks should be a priority, though he urged against rushing any modifications. “We shouldn’t rush anything,” he remarked, signaling a preference for careful research and consensus-building among Bitcoin Core developers and the broader community.
At press time, BTC traded at $98,337.

In recent years, cryptocurrency has taken the world by storm, offering decentralized, secure, and borderless financial transactions. However, with the rapid development of quantum computing, a new concern is emerging in the crypto space. Could this futuristic technology one day destroy the very foundation of Bitcoin, Ethereum, and other blockchain networks?
Let’s explore the truth behind this threat and what the future might hold.
🔐 How Cryptocurrency Security Works Today
Most cryptocurrencies rely on public key cryptography to keep transactions secure. For example:
Bitcoin uses Elliptic Curve Digital Signature Algorithm (ECDSA)
Ethereum uses a similar cryptographic system for wallet and transaction security
This technology ensures that while you can publicly share your wallet address, no one can reverse-engineer it to find your private key — unless they had unimaginable computing power. Enter quantum computing.
⚛️ What is Quantum Computing?
Quantum computers don’t work like traditional computers. Instead of using bits (0s and 1s), they use qubits, which can exist in multiple states at once, thanks to quantum superposition. This allows them to process complex problems at speeds far beyond anything classical computers can achieve.
One powerful quantum algorithm, Shor’s algorithm, can factor large numbers exponentially faster than classical computers — and that’s exactly what threatens modern encryption.

🚨 What Could Happen to Crypto?
If quantum computers become powerful and stable enough, they could:
Break the private keys protecting crypto wallets
Forge digital signatures, allowing fake transactions
Undermine the security of blockchain protocols relying on traditional cryptographic algorithms
In the worst-case scenario, a hacker with a powerful quantum computer could access anyone’s wallet and steal their funds.
🧘‍♂️ Why It’s Not an Immediate Threat
Before you start panic-selling your coins, take a deep breath. Here’s why:
1. Quantum computers are not ready yet
The most advanced quantum computers today have only around 100–1,000 noisy qubits.
To break Bitcoin’s encryption, experts estimate we’d need at least 10 million stable qubits — which could take decades.
2. Post-Quantum Cryptography is Coming
Researchers are already developing quantum-resistant encryption algorithms, also known as post-quantum cryptography (PQC).
Blockchains can upgrade to these algorithms through forks or system updates.
3. Crypto Projects are Preparing
Ethereum developers are actively researching quantum-safe solutions.
Projects like Quantum Resistant Ledger (QRL) and Algorand are already integrating quantum-safe technologies.
🔮 The Future of Crypto in a Quantum World
Cryptocurrency won’t disappear because of quantum computing. In fact, this challenge may drive innovation in blockchain technology and cybersecurity.
Eventually, the entire crypto ecosystem will likely transition to quantum-resistant algorithms, ensuring that digital assets remain safe even in the face of next-gen computing.

✅ Final Thoughts
Yes, quantum computing poses a real future threat to the current cryptographic methods used in cryptocurrencies. But no, it is not a danger today. The crypto community is aware, alert, and already working on robust solutions.
So, while it’s wise to stay informed, there’s no need to fear that quantum computers will suddenly empty your wallet overnight.

⚠️ BlackRock just dropped a bombshell in their Bitcoin ETF filing:

Quantum computing is now listed as a threat.
This isn't FUD — this is the future knocking.

🧠 Why it matters:
Bitcoin relies on ECDSA — a cryptographic method that’s currently secure.But quantum computers could reverse-engineer your private key from a public key.If that happens, anyone can drain your wallet.
🔓 And here’s the scary part:
Every time you send BTC, you reveal your public key.So past transactions = future attack vectors.📉 If quantum computing breaks ECDSA, billions in BTC — including from exchanges, funds, and OG whales — could be stolen in seconds.
🧬 How far away is this?
Current quantum machines aren't there yet.But with AI + quantum R&D exploding, 5–10 years isn't unrealistic.

💼 BlackRock knows this.
That’s why they’ve flagged it.This isn’t a meme. It’s real institutional-level foresight.
🛡 So what can be done?
Move to quantum-resistant signatures (e.g., XMSS, lattice-based schemes)Use fresh wallet addresses for every transactionSupport future forks or updates that address post-quantum threats

🔥 Final thought:
“Bitcoin is secure — until it isn’t.”

Now that BlackRock is sounding the alarm, it's time for the crypto community to think ahead — or risk playing catch-up.
