StarkWare reports 79% reduction in quantum-secure Bitcoin transaction costs to $67

StarkWare announced on September 23 that the estimated GPU computing cost to prepare a quantum-secure Bitcoin (QSB) transaction has dropped to under $67, a 79% decrease from the $320 cost of the first mainnet transaction in August. The cost reduction follows a challenge launched on September 16 by StarkWare, Yukon Research, and Eigen Labs, which resulted in 62 adopted improvements for transaction construction software. The QSB initiative, introduced by StarkWare researcher Avihu Levy in April, provides hash-based quantum resistance without altering Bitcoin consensus rules, though it remains intended as an emergency measure.
