Quantum-Safe Bitcoin Transaction Costs Plunge 79%

The estimated cost of constructing a 'quantum-safe' Bitcoin transaction has dropped by 79%, according to StarkWare. After a week of optimization work, the cost fell from around $320 in August to approximately $67.

This improvement is thanks to participants in the Quantum-Safe Bitcoin Optimization Challenge, which targeted the GPU-heavy steps needed for building a transaction using the Quantum-Safe Bitcoin (QSB) design.

The challenge resulted in 62 accepted improvements across two tasks required for QSB transaction preparation. While these gains are demonstrated in benchmark cost estimates on Yukon's QSB dashboard, StarkWare notes that they have not been confirmed through additional mainnet transactions.
