The estimated computational cost to prepare a specialized transaction of Bitcoin resistant to quantum computing fell from about $320 to about $66, according to reports on the optimization challenge. The figure still depends on simulations and not on a complete operation in production. Progress comes as researchers warn that millions of BTCs have public keys exposed and debate is growing on how to prepare the network for a threat that has not yet…
