Yukon & StarkWare Unlock Quantum 80% Drop In Bitcoin Costs

Yukon Research and StarkWare report a nearly 80 percent reduction in the cost of quantum-safe Bitcoin transactions within a single week. A quantum-safe Bitcoin transaction now requires approximately $67 in GPU compute, a dramatic decrease from the $320 cost of the first such transaction mined just one month ago. The speedup stems from the Quantum-Safe Bitcoin Optimization Challenge, where transaction pinning now runs at over 820 million verified candidates per second on an RTX 4090, up from a baseline of 146.09 million.

AI Competition Achieves 79% Reduction in Quantum-Safe Bitcoin Costs

The challenge’s dashboard calculates the estimate by applying measured speed improvements to the cost of the August transaction, demonstrating a tangible link between optimization and affordability. Subset selection has gone from about 62 million to 623,518,629, a little over ten times faster. The most successful optimization approaches in the challenge have come from the models Opus 5 and Fable 5.1, with GPT-6 Astra, GPT-5.6, Grok 4.6 and Kimi close behind on both leaderboards.
