At Build to Last 2026, Saint-Gobain Vietnam announced it has achieved “Zero Carbon” manufacturing for its DURAflex fiber cement sheet plant in Quảng Trị, with no carbon emissions for Scope 1 and Scope 2. The company said it is the first in its industry to reach this milestone. The Zero…
A GitHub repository presented Quantum Safe Bitcoin, or QSB, a transaction scheme designed to keep Bitcoin secure against a large-scale quantum adversary without requiring a soft fork. The project says it works entirely within Bitcoin’s existing legacy script constraints and consensus rules. The design replaces Bitcoin’s usual ECDSA security assumptions with hash-based ones. In the repository’s description, QSB uses a hash-to-signature puzzle built around RIPEMD-160 and a HORS-like one-time signature scheme, while keeping the logic inside current Bitcoin script limits. The tradeoff is cost and complexity: the repo estimates about $75 to $150 in cloud GPU compute per transaction, and says the transaction would be non-standard, requiring miner-direct submission rather than normal relay. What makes the proposal interesting is that it sketches a fallback path Bitcoin could use without waiting for a protocol change. At the same time, the compute bill and relay limits make QSB look far more practical for exceptional or high-value transfers than for ordinary daily payments.
Premium gym chains are entering a “golden era” that is ending or already in decline, as rising operating costs collide with shifting consumer preferences toward more flexible, community-based ways to exercise. Long-term memberships are shrinking, margins are pressured by higher rents and facility expenses, and competition from smaller, more personalized…
