AI programming reduced estimated GPU cost for quantum-safe Bitcoin transactions from $320 to $66.

The previous estimate was based on an August-mined transaction requiring 3,100 hours of computation.

The new method requires direct transactions to miners and cannot protect already exposed public keys.

The cost reduction is a positive step for Bitcoin's long-term security.

Story

StarkWare has announced that a week of AI-powered programming significantly reduced the estimated GPU cost for creating a quantum-safe Bitcoin transaction. The cost projection dropped from approximately $320 to $66. The previous $320 estimate was based on a Bitcoin transaction mined in August, which required about 3,100 hours of computation using around 100 GPUs. However, the new $66 estimate has not yet been demonstrated in another mined transaction. The method requires sending transactions directly to miners and cannot protect coins with already exposed public keys. Despite these limitations, the substantial cost reduction is a positive indicator for the feasibility of quantum-safe solutions. This bolsters confidence in Bitcoin's future resilience against potential quantum computing threats and highlights ongoing efforts to enhance blockchain security.

Issue context

The crypto market demonstrates resilience as Bitcoin ETFs continue to attract significant capital inflows despite a recent price dip. This indicates sustained institutional interest, which could act as a crucial support mechanism for Bitcoin's price structure. Concurrently, the impending quarterly expiry of Bitcoin and Ethereum options may introduce heightened short-term volatility as traders adjust their positions.

Sustained institutional inflows into Bitcoin ETFs suggest underlying demand that may cushion price dips. However, be mindful of the upcoming options expiries, which could introduce heightened market volatility in the short term. Your positions may be affected by these movements, so exercise caution.
