## Bitcoin’s ‘last resort’ quantum-safe solution just got 79% cheaper: StarkWare A weeklong optimization challenge cut the estimated GPU cost of preparing an experimental quantum-resistant Bitcoin transaction to under $67, potentially making the “last-resort measure” a little easier on the wallet. The estimated computational cost to prepare a quantum-resistant Bitcoin transaction has fallen below $67 after a week of optimization, down from the roughly $320 spent on the first such mainnet transaction in August, according to StarkWare. The results came after participants in the Quantum-Safe…
