A crowdsourced challenge involving over 100 researchers and AI agents reduced the quantum computing cost of a key step in attacking Bitcoin and Ethereum by 86% in two months, achieving a score well below Google's previous benchmark. The optimized point-addition circuit for the secp256k1 elliptic curve now requires fewer logical qubits and Toffoli gates, shrinking the quantum attack margin. While this does not enable an immediate attack, it highlights the urgency for blockchain networks to accelerate post-quantum security measures, with Ethereum targeting 2029 for full quantum resistance. Experts emphasize that the threat is now driven by both hardware and algorithmic advances, underscoring the need for early migration across blockchain systems before practical quantum attacks become feasible.
Blockstream recovered about 3,400 BTC from the 4,000 BTC stolen in a Liquid Network exploit but refuses to pay the $47 million ransom demanded for the remaining 598.5 BTC. The exploit exploited a software bug in the Elements codebase, allowing attack...
Blockstream announced it will not pay a ransom for the roughly 598.5 BTC still held by hackers after the Liquid Network exploit, calling the withholding of coins theft rather than responsible disclosure. The hackers stole about 4,000 BTC from a feder...
Global bond yields have surged, with the US 10-year yield nearing 5% and the UK 10-year yield heading toward 6%, signaling economic stress. This rise in yields has weighed on Bitcoin, pushing its price down to $76,500. Bitcoin is currently bouncing w...
Kroger reported a 5% increase in adjusted earnings per share to $1.09 for Q2 2026, driven by cost savings and profitable eCommerce growth. Despite a slight 0.2% rise in identical sales excluding fuel, the company lowered its full-year sales guidance ...
Lazard, Inc. reported preliminary assets under management (AUM) of approximately $290.3 billion as of August 31, 2026. This figure reflects market appreciation of $3.7 billion, net outflows of $1.8 billion, and foreign exchange gains of $1.5 billion ...
