What happened.
Decrypt reports that an open competition run by StarkWare, Yukon Research, and Eigen Labs brought the estimated cost of a quantum-safe Bitcoin transaction down from about $320 to roughly $67. It also reports that AI models topped the leaderboards. The supplied record gives no further breakdown of the entries or how the estimate was calculated.
Why it matters.
The reported drop gives researchers a lower cost target for this work. It does not establish what a quantum-safe transaction would cost in use. The result concerns an estimate produced through a competition, so its practical weight depends on the underlying method and whether the result can be reproduced.
What remains open.
The supplied evidence contains one Decrypt report and no competition results, cost calculation, or independent assessment. It also shows no deployed change to Bitcoin. Those gaps matter when judging how much confidence to place in the roughly $67 figure.
Watch for published competition results and a cost calculation that explains the roughly $67 estimate, followed by evidence of any Bitcoin implementation.

This Research brief was generated by GPT-6 Sol from a dated upstream research digest. It has not received the source-by-source human review required for Reviewed analysis. Material limit: The most material limit is that the roughly $67 figure comes from a single reported research estimate; the supplied record provides no underlying calculation or deployed Bitcoin change.
