Project 11, a quantum computing research company, announced a competition titled the Q-Day Prize on April 16, 2025. To win, participants must break the largest portion of a toy version of Bitcoin’s ECC key using Shor’s algorithm on a quantum computer. The deadline is April 5, 2026. The prize: 1 BTC.
The mission behind the competition
According to researchers, quantum computers will be capable of instantly solving tasks that modern-day computers would need 47 years to complete. Such computational power is widely seen as a threat to cryptocurrency networks, as they would be able to brute-force encrypted data. Bitcoin and Ethereum (ETH) are especially vulnerable, as newer coins were made with quantum resistance in mind.
Although some see the contest as a threat to Bitcoin’s security, Project 11 claims the real mission is to avoid future security breaches associated with quantum computing progress, estimate the risks, and take proper action to respond to the threat in time.
As Project 11 puts it in the announcement on the company’s X account, the mission is to protect six million bitcoins. Project 11 explains that currently, Bitcoin’s security heavily relies on elliptic curve cryptography, allegedly vulnerable to quantum computers running Shor’s algorithm. Breaking this protection is a question of time. The idea behind the competition is to benchmark this threat and get practical data to work with in creating solutions that will protect the Bitcoin network from quantum computers.
According to the conditions list, Project 11 does not anticipate that someone will break the entire Bitcoin key. The company urges competitors to try to break small portions of the 256-bit key. Project 11 offers toy keys from 1 to 25 bits in length. As the company puts it, even breaking a 3-bit key would be big news.
Importance for transparency
Project 11 emphasizes the need for transparent stress testing, open to all, to provide an honest and clear picture of how real the quantum threat is.
Here’s what the company itself says on the matter:
“Quantum computing is advancing fast, and the impact on cryptography is inevitable. Instead of waiting for breakthroughs to happen behind closed doors, we believe in facing this challenge head-on in a transparent and rigorous manner.
The QDay Prize is about testing real quantum capabilities, staking out the frontier of cryptanalysis, and ensuring the world is ready for what comes next. The future of cryptography depends on it.”
Awarding people for cracking Bitcoin key cryptography is also a bold move that may increase awareness about the quantum computing threat to Bitcoin, as not everyone in the community knows about it, and many downplay this danger.
Transparency of the competition will ensure the threat is real and not something made up. Thanks to the submitted task solutions being visible to everyone, the threat may become auditable and reminiscent of open-source software in this regard.
How real is the quantum computing threat?
Project 11 notes that no one has ever managed to break any ECC key used in real-life cryptography, either via classical methods or quantum computing. Nevertheless, quantum computing keeps evolving, and the threat is real. The Project 11 website mentions that the National Institute of Standards and Technology (NIST) is actively transitioning to post-quantum cryptography (PQC), as widely adopted ECC is considered vulnerable to potential quantum attacks. Several brands of wallets now promote themselves as quantum-resistant ledgers.
According to existing estimations, a quantum computer needs to reach 2,000 qubits to break ECC keys. Currently, various companies work on quantum chips. Yet, their capacity is far beyond the 2,000 qubits. For instance, Google’s Willow chip reaches 105 qubits. IBM’s Heron is more powerful, with 150 qubits. QuEra is a quantum computing-focused company. Its analog quantum computer allegedly reaches the 256 qubits mark.
Various prominent experts and professionals in the cryptocurrency community have voiced their concerns about the potential dangers of quantum computation for Bitcoin.
Opinions
Tether CEO Paolo Ardoino took to X to convey his optimistic stance on the future of Bitcoin in the quantum computing era. He seemingly doesn’t doubt that quantum computers will eventually crack the ECC key. By that time, a solution will already have been found, and all Bitcoin owners will have moved their assets to quantum-resistant addresses. The “lost wallets,” including Satoshi’s addresses, will be hacked, and those coins will enter circulation.
John Lilic of Telos Blockchain outlines the opposite side of the quantum computer use case. He points out that they can be used not to loot crypto from wallets with lost keys but to give legitimate owners an opportunity to regain access to their locked bitcoins.
Different experts estimate that quantum computers will enter the picture between 2030 and 2050. Either way, there is enough time for developers to come up with protection measures, while even modern-day technologies allow people to protect their coins. Quantum computers are harmless for those using cold wallets, multisig wallets, or modern quantum-resistant wallets.

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.

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.

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.

The intersection of quantum computing and cryptocurrency is set to redefine the future of blockchain technology. While blockchain has been praised for its security and decentralization, the rise of quantum computing presents both challenges and opportunities that could shape the next phase of the crypto industry.
The Quantum Threat to Cryptocurrencies!
Most cryptocurrencies rely on encryption methods such as RSA and ECC to secure transactions and protect private keys. These cryptographic techniques work because traditional computers would take an impractical amount of time to break them. However, quantum computers, with their ability to process information exponentially faster, could potentially crack these encryption methods in a matter of seconds.
If quantum computing advances faster than the adoption of quantum-resistant cryptography, the security of blockchain networks could be compromised. Private keys could become vulnerable, digital assets could be stolen, and existing consensus mechanisms might no longer be viable. This raises an urgent need for blockchain networks to adopt quantum-resistant security measures.
How Quantum Technology Can Strengthen Blockchain?
While quantum computing poses a risk to current encryption standards, it also has the potential to enhance blockchain technology. Researchers are already working on post-quantum cryptographic solutions designed to withstand attacks from quantum computers. Quantum-resistant algorithms, quantum random number generators, and quantum-enhanced consensus mechanisms could help secure and optimize blockchain networks.
Beyond security, quantum computing could also improve blockchain scalability. The computational power of quantum processors can help speed up transactions, reduce fees, and enhance smart contract efficiency. Instead of undermining blockchain technology, quantum advancements could drive its next evolution.
The Need for Quantum-Ready Blockchain Solutions!
As the crypto industry prepares for a post-quantum future, projects focusing on quantum-resistant security are gaining attention. QuantumX is among the initiatives working on a blockchain that integrates post-quantum cryptographic techniques. By addressing the security risks posed by quantum computing and leveraging its potential benefits, QuantumX aims to create a blockchain network that remains sustainable in the long term.
The ability to adapt to emerging technologies will determine the resilience of cryptocurrencies in the coming years. Investors, developers, and blockchain enthusiasts should stay informed about how quantum advancements will shape the industry and which projects are leading the transition to quantum-ready blockchain networks.
Quantum computing is not just a challenge for crypto it is also an opportunity to build a more secure, scalable, and efficient digital economy.🔥

Concerns Over the Security of Early Bitcoins
Emin Gün Sirer, the CEO of Avalanche, has sparked a debate about the security of bitcoins mined in the early days of the cryptocurrency. He proposed freezing approximately 1 million bitcoins, often associated with pseudonymous creator Satoshi Nakamoto, due to potential future threats posed by quantum computing.

Quantum Computing as a Potential Threat
Sirer highlighted that early bitcoins use the outdated Pay-to-Public-Key (P2PK) cryptographic standard, which exposes public keys and makes these coins more vulnerable to quantum attacks. Unlike modern formats such as Pay-to-Public-Key-Hash (P2PKH) or SegWit, P2PK lacks additional layers of security.

He suggested that the Bitcoin community consider freezing these older coins or setting a "sunset date" beyond which they could no longer be spent. This measure, he argued, would protect the integrity of the Bitcoin network from future technological advances.
Quantum Chip Willow and Future Capabilities
Google recently unveiled its quantum chip, Willow, which can perform calculations that would take current supercomputers billions of years to complete. Although Willow is not yet capable of breaking Bitcoin's encryption, it represents a significant step toward practical quantum computing.
Differences Between Modern and Early Bitcoin Addresses
Modern Bitcoin wallets use advanced formats that conceal public keys through hashing. These formats provide added security, as quantum computers would need to reverse the hash, an extremely complex task. In contrast, P2PK addresses store public keys in plain text, making these coins more vulnerable to quantum attacks.
Mixed Reactions to the Proposal
Sirer's proposal has sparked mixed reactions. Some view it as a proactive measure to ensure security, while others argue it contradicts Bitcoin's principles of decentralization and freedom. Critics also highlight the challenges of identifying and freezing specific coins, as well as the potential precedent it could set for future changes to Bitcoin's rules.

Quantum Computing: A Challenge for the Future
Although current quantum computers cannot yet break Bitcoin's encryption, Sirer emphasizes the need for the community to prepare for potential consequences. Quantum technologies are advancing rapidly, and while the threat remains speculative, preventive measures could help mitigate future risks. "Realistic attacks on cryptocurrencies are still far off, but we must closely monitor developments in quantum computing over the coming decades," Sirer concluded.

#QC chips are a potential threat to most existing cryptographic systems, including the ones securing many blockchain networks. QC is capable of factoring numbers faster than RSA and elliptic curve cryptography that underpins some of the blockchain security. However, since quantum technology develops rather swiftly, this problem requires some preventive measures in terms of #cybersecurity .
#quantumcomputers use quantum mechanisms to solve problems that will take a classical computer years to solve. For example, the actualization of signature schemes depending on the elliptic curves is dangerous because QC can break it exponentially. This vulnerability encompasses many of the internet protocols on which many blockchains rely, making the call for quantum-resistant solutions timely.
But not all cryptography is threatened. AES in particular and, more specifically, AES-256 continues to generally prove resistant more so given the fact that it is grounded on non-algebraic processes including bit permutation. Unfortunately, today’s quantum computers are not useful in breaking these structures and provide a solid ground for some encrypted methods.
Promising initiatives are already on the way to doing so. Gradually migrating to quantum-safe signatures is becoming part of the blockchains’ development strategies, so they can resist the evolution of QC. It’s crucial to argue that staying ahead of quantum developments allows the projects to prevent future threats that may be detrimental to ecosystems that support projects, thereby protecting users’ trust and system integrity.
This transition to quantum resistance also paves the way to #SocialMining for blockchain communities where people can engage in popularizing the advantages of secure encryption. Through sharing educational posts, making graphics or having general discussions about the effects of QC, the participants propagate the use of quantum-resistant solutions. Social Mining encourages these actions, thus helping to create a synergy for the decentralized world’s defence.
Quantum computing disrupts the existing business models but the threats can be managed once organizations start to act and involve their communities. But as we move into the future of blockchain, being quantum resistant will help safeguard its future, and the trust on which it is built.
