Bitcoin developers are debating a radical change to how the network would respond to a future quantum computing threat: don’t freeze vulnerable coins unless someone proves the threat is real. But there’s a catch: The proposal assumes the attacker will reveal capability for a bounty instead of maximizing profit through theft. A proposal published this…
TLDR: Quantum Safe Bitcoin works within Bitcoin’s existing consensus rules, requiring no soft fork or miner signaling. Each QSB transaction costs between $75 and $200 due to heavy off-chain GPU computation requirements. QSB replaces ECDSA signature security with hash-based proofs that quantum computers cannot easily break. Levy frames QSB as a last-resort emergency tool, not…
Quantum computing is moving from theory to practice, and a new whitepaper warns that major cryptocurrencies need to react much faster than they have so far. The study shows that once a powerful enough quantum computer exists, it could break the cryptography behind Bitcoin, Ethereum and other chains in minutes, putting both long‑dormant and active…
Solana co-founder Anatoly Yakovenko warned that Bitcoin developers must act to prepare for a possible quantum computing breakthrough that could render the network’s current security measures obsolete. Speaking at the All-In Summit 2025, Yakovenko said there’s a “50/50” chance quantum computers will be powerful enough within five years to break the cryptographic protections securing Bitcoin…

Quantum computing is no longer a distant sci-fi concept. According to Nvidia CEO Jensen Huang, it’s now nearing an inflection point. This bold claim came during his keynote at the GTC Paris developer conference. He believes quantum computing is close to solving real-world problems—a leap that many in the tech world didn’t expect so soon….
Investors Prepare for a Data-Heavy Week Investors are gearing up for a critical week of economic data, with the spotlight on the highly anticipated U.S. jobs report set for release on Friday. This crucial labor market update will be preceded by the Job Openings and Labor Turnover Survey (JOLTS) for December on Tuesday. Additionally, the…
Quantum computing has taken a significant leap forward with groundbreaking research from the University of New South Wales (UNSW). Published in Nature Physics, this research showcases the creation of a “Schrödinger’s cat” state within a silicon chip. This achievement holds the potential to overcome critical challenges in quantum error correction and reliability, bringing quantum computing…
