How Much Bitcoin Is Quantum-Vulnerable? Researcher Says 6.9 Million BTC
Project 11 CEO Alex Pruden is challenging a CoinShares estimate that only 10,200 bitcoin sit in “genuinely” quantum-vulnerable legacy addresses, arguing instead that roughly 6.9 million BTC could be exposed if cryptographically relevant quantum computers arrive sooner than the market expects. The dispute, amplified by Castle Island partner Nic Carter, goes to the heart of […]

Quantum risk has become a recurring stress point in Bitcoin discourse, often framed as an existential threat. The claim usually follows a familiar arc: quantum computing is advancing quickly, cryptography is vulnerable, and Bitcoin isn’t adapting fast enough. Marty Bent doesn’t buy that framing. In his Dec. 14 episode, Bent acknowledged that quantum computing represents […]

Quantum computing is a form of computing based on quantum physics. Where classical computers rely on bits (zeros or ones) to make calculations, quantum computers use quantum bits (qubits) that leverage quantum mechanics to exist in a “superposition”: a combination of zero and one, with some ...
Quantum computing still has a long way to go before posing a threat to blockchain technology. Quantum computing has raised concerns about the future of cryptocurrency and blockchain technology in recent years. For example, it is commonly assumed that very sophisticated quantum computers will one day be able to crack present-day encryption, making security a serious concern for users in the blockchain space.The SHA-256 cryptographic protocol used for Bitcoin network security is currently unbreakable by today’s computers. However, experts anticipate that within a decade, quantum computing....
Ethereum is beginning to formalize its post-quantum security push in public. ETH Foundation researcher Will Corcoran used a presentation at the Institutional Ethereum Forum in New York to lay out both the threat model and the protocol work already underway. The effort matters well beyond ETH, he argued, because the core bottleneck is not unique […]
