40 stories about Quantum from across the crypto press, curated and summarized daily. Most recent: Oct 19, 2026.
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.
Citi analysts warn that Bitcoin's security could be at greater risk from quantum computing than Ethereum's. The concern stems from Bitcoin's reliance on elliptic curve cryptography, which may be more vulnerable to quantum attacks.
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.
Strategy (formerly MicroStrategy) sold a portion of its Bitcoin holdings for the first time since 2022, citing emerging quantum computing risks. The company's stock dropped following the announcement, highlighting investor concerns about the security of Bitcoin in the face of advancing technology.
Andrew Gault, a venture capitalist who funded quantum hardware labs, warns Bitcoin's biggest quantum risk isn't wallet keys but a broader threat. Google's own security team shifted focus in the same direction this March.
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 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.
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.
Analytics firm Glassnode warns that nearly 10% of Bitcoin's supply could be compromised by a quantum computing breakthrough. The firm recommends implementing quantum-resistant solutions like BIP-360 to mitigate this risk.
Binance Smart Chain's quantum-resistant upgrade succeeded in its test, but it reduced transaction speed by 40%. The trade-off highlights the challenges of balancing security and performance in blockchain networks.
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.
Citi warns that rapid advances in quantum computing could soon threaten Bitcoin and other cryptocurrencies. Bitcoin's security model is particularly at risk due to its reliance on cryptographic methods that quantum computers could potentially break.
A new report warns that quantum computing could break Bitcoin's security, potentially putting $3 trillion in digital assets at risk. The report suggests it may already be too late to fully protect the network.
