Bitcoin price trades near $84,000, down by a huge 3.5% on the day, but the more interesting number this week has nothing to do with its prediction. It’s $67.

That’s the new estimated cost to build a quantum-resistant Bitcoin transaction, down from $320 when StarkWare mined the first one on mainnet back in August, a 79% reduction achieved in a single week of open optimization work.The move came out of the Quantum-Safe Bitcoin Optimization Challenge, a joint effort between StarkWare, Yukon Research, and Eigen Labs.

According to the report, they invited developers, researchers, and even AI agents to shrink the GPU-hours needed to construct the transaction.
