Google says its Willow quantum chip can prepare certain states needed for advanced calculations with about 40 times fewer errors, improving one part of the hardware needed for a future attack on Bitcoin wallets. The report does not mean current Bitcoin wallets have been cracked: a capable, large-scale quantum computer remains a future concern.
Nine crypto companies have launched the Quantum Alliance to coordinate preparation for possible quantum attacks on blockchain security. The group agrees the risk deserves attention, but not on when it may arrive or whether vulnerable bitcoin should be frozen; a Google research advance adds to the debate without setting a clear countdown.
Bitcoin Magazine reports researchers built a working post-quantum defense for Lightning, but the report lacks design details or performance data. Separately, Coinbase urges Bitcoin to adopt flexible addresses and backup quantum-proof keys now.
Ethereum researchers warn that AI could break the cryptographic signatures protecting Bitcoin, Ether, and other tokens within months, not years. They urge users to move funds to new addresses as a precaution. Ethereum co-founder Vitalik Buterin supports this 'bunker mode' but warns against rushing the process.
MIT professor Muriel Médard contends that existing mathematical tools, not quantum computers, are the key to making blockchains quantum-safe. She believes classic cryptography can be adapted to protect digital assets from future threats. This approach could save the industry billions in potential losses.
QuFi has launched a new platform that uses post-quantum cryptography to verify digital asset transactions without altering existing blockchain settlement networks. The platform has been successfully tested on Bitcoin's testnet, demonstrating its potential to secure transactions against future quantum computing threats.
Researchers have proposed a cryptographic method to safeguard Bitcoin and other blockchain wallets against future quantum attacks. This approach ensures compatibility with existing addresses, preventing the need for a hard fork.
Coinbase is building a post-quantum custody system and funding Bitcoin's cryptographic upgrades to protect against future quantum computing threats. While the threat is not imminent, quantum computers could one day break Bitcoin's cryptography.
Project Eleven has proposed a method to help Bitcoin users recover their wallets after a quantum computer breaks the network's cryptographic protections. The plan involves a post-quantum cryptographic proof to verify ownership of wallets.
StarkWare's CEO Eli Ben-Sasson criticized the crypto industry for ignoring quantum computing threats and announced a roadmap for Starknet to address these risks. The company aims to make the blockchain more resilient against future quantum attacks.
Algorand is working on upgrades to protect its blockchain from potential threats posed by quantum computing. The company plans to have these security measures in place by the end of 2027. This is a proactive step to safeguard user data and transactions against future technological advancements.
Algorand has announced a roadmap to achieve quantum resistance by 2028, a critical step to protect against future quantum computing threats. This involves updating both user wallets and the core protocol infrastructure, a process that could take years.
The SPHINCS- proposal aims to reduce the cost of post-quantum signature verification on Ethereum while the network works toward a longer-term solution.
A Coinbase-convened panel of top cryptographers agrees Bitcoin should start preparing for quantum attacks now, but declines to take a position on whether millions of vulnerable coins, including many linked to Satoshi Nakamoto, should eventually be frozen.
A new analysis from ChainQuery reveals that 25.3% of all Bitcoin is stored at addresses where the public key has been exposed, making those funds potentially vulnerable to future quantum computing attacks. The risk is not immediate but highlights a significant security consideration for long-term holders.
Coinbase's quantum advisory council urges immediate action to protect Bitcoin from future quantum computing threats. Developers must start migrating to post-quantum cryptography now to avoid potential vulnerabilities. The biggest challenge will be addressing abandoned and vulnerable coins.
The Stellar Development Foundation has released a three-step plan to protect its blockchain from future quantum computing threats. This move highlights the growing concern about quantum computers breaking current cryptographic defenses.
Artificial intelligence is speeding up the timeline for quantum computing to break current cryptographic protections. Security experts are calling for a rethink of digital security to prepare for this looming threat. The urgency is growing as AI advances could shorten the timeframe for quantum attacks.
The Ethereum Foundation allocated $30 million in Q1 2026 to strengthen the network's foundations, focusing on cryptography, zero-knowledge proofs, security, and protocol research. This investment supports critical infrastructure and tools across the Ethereum ecosystem.
The crypto industry is taking steps to address potential security threats from quantum computing. Experts warn that future quantum computers could break current encryption methods, prompting proactive measures to safeguard digital assets.
A blockchain startup claims its quantum-resistant technology could safeguard Satoshi’s untouched Bitcoin and other dormant funds. The plan involves a soft fork to freeze and protect vulnerable BTC.
SolRouter, a privacy-focused AI inference project, claims its cryptographic privacy is stronger than Venice's. The project uses proof-based privacy rather than trust-based systems. This could impact users looking for secure AI interactions.
Ethereum is planning to replace its current BLS signatures with post-quantum secure alternatives to protect against future quantum computing threats. This move aims to future-proof the network against potential vulnerabilities that could arise from advancements in quantum technology.
Glassnode has analyzed how much Bitcoin could be at risk from quantum computing attacks. They found that about 23% of Bitcoin's supply is potentially vulnerable due to past transaction patterns.
