The estimated computational outgo to hole a quantum-resistant Bitcoin transaction has fallen beneath $67 aft a week of optimization, down from the astir $320 spent connected the archetypal specified mainnet transaction successful August, according to StarkWare.
The results came aft participants successful the Quantum-Safe Bitcoin Optimization Challenge recovered ways to propulsion down the GPU computation needed to physique a quantum-safe Bitcoin transaction.
The simplification could marque the experimental defence (which doesn’t necessitate changes to the network’s statement rules) against aboriginal quantum attacks much applicable for Bitcoin holders. However, the latest optimizations person lone been demonstrated successful benchmark tests.
“A operation that costs a fewer 100 dollars per transaction is simply a demo. One that costs $67 is person to thing a holder with a ample unexposed equilibrium mightiness scope for successful an emergency,” StarkWare wrote successful its Sept. 23 update. The dashboard present shows the estimated outgo has dropped to $66.
Quantum-Safe Bitcoin an “emergency” solution
StarkWare researcher Avihu Levy published the Quantum-Safe Bitcoin (QSB) plan successful April, outlining a mode to adhd hash-based extortion against quantum attacks without changing Bitcoin’s statement rules. At the time, helium described it arsenic a “last edifice measure” owed to costs, complexity and constricted applicability, portion continuing to advocator for protocol-level changes.

According to StarkWare, the archetypal QSB transaction was mined and confirmed connected Aug. 26, with engineering enactment from Tomer Giladi and nonstop submission done MARA’s Slipstream service. Preparing it required astir 3,100 GPU-hours crossed astir 100 GPUs, astatine a compute outgo of astir $320, excluding Bitcoin web fees.

To find ways to bring that outgo down, StarkWare, Yukon Research and Eigen Labs launched the QSB situation connected Sept. 16, inviting developers, researchers and AI agents to marque the transaction-building bundle faster and much efficient.
In its latest update, StarkWare said the situation produced 62 accepted improvements crossed 2 computational tasks needed to hole a QSB transaction. According to StarkWare, this ended up cutting the estimated computing outgo by astir 79%, based connected benchmark tests.
The improvement comes amid expanding interest that a sufficiently almighty quantum machine could interruption the elliptic-curve integer signatures utilized by Bitcoin, perchance allowing attackers to bargain coins whose nationalist keys are exposed.
Researchers are processing quantum-resistant protections, including QSB. However, StarkWare said it inactive favors a brushed fork — a alteration to Bitcoin’s statement rules — arsenic a amended “long-term answer” for wide quantum extortion connected Bitcoin.
