On May 4, Galaxy Digital Research Director Alex Thorn noted that as quantum computing hardware advances, the Bitcoin community is shifting from decentralized debate to preliminary consensus on the quantum threat. The core approach is to phase in post-quantum cryptography (PQC) via a soft fork, upgrading the address system and enhancing long-term security. The report notes Bitcoin’s signature mechanism—based on the Elliptic Curve Digital Signature Algorithm (ECDSA)—is theoretically vulnerable to Shor’s algorithm. Roughly 2 million BTC tied to early p2pkh addresses face a potential “collect now, decrypt later” risk due to exposed public keys. The community is leaning toward a “migration window” mechanism: guiding users to move funds to new quantum-resistant addresses, with unmigrated funds to be frozen or destroyed after a multi-year grace period to avoid market disruptions from extreme scenarios. Additionally, the consensus calls for boosting “cryptographic agility,” letting the p

Saudi Energy Minister Abdulaziz bin Salman has long led OPEC+ decision-making by leveraging Saudi production capacity and royal backing from Crown Prince Mohammed bin Salman. In recent years, however, his more centralized approach has narrowed negotiating room for member nations—fueling dissatisfaction, including from the UAE. The UAE and Saudi Arabia have a long-running quota dispute. While Abu Dhabi secured a quota increase in the past, tensions have not eased fundamentally. UAE Energy Mi
