Microsoft Majorana 2 dey boost qubit reliability, dey raise Bitcoin security “Q-day” risk

Microsoft show Majorana 2 topological quantum chip for Build, dem say qubits dey 1,000x more reliable pass old designs. Dem report qubit life about 20 seconds, some fit last up to ~60 seconds. Di company tie progress to agentic AI through Microsoft Discovery platform and talk say dem get more scalable quantum computing roadmap by 2029. For crypto traders, main story remain Bitcoin security under “Q-day” risk. Di article repeat worry say powerful quantum computers fit break today public-key cryptography, wey fit threaten transaction signatures. E cite Glassnode research wey talk say about 6 million BTC (around $469B) fit dey exposed when quantum era land, and e point out Bitcoin-specific headwinds (slower ecosystem upgrades and old Satoshi-era coins wey never move for years). Timeline uncertainty na main market variable: one side project functional quantum computers by 2032, while another talk as soon as ~4 years. Overall, dis na meaningful technical update but e more likely be long-horizon catalyst—unless markets quick-reprice Bitcoin security timelines soon.
