StarkWare Estimates 79% Cost Reduction for Quantum-Secure Bitcoin Transactions

StarkWare announced that the estimated GPU computing cost to prepare a quantum-secure Bitcoin transaction has been reduced from approximately $320 to $66, marking a 79% decrease. This initiative aims to mitigate the future risk of quantum computers deriving private keys from public keys. While the cost reduction is significant, the solution remains in the testing phase and has not yet been verified through an actual mined transaction. Limitations persist, as these transactions must be sent directly to miners and cannot propagate through the standard Bitcoin network, nor can they protect wallets with already exposed public keys.
