Perhaps the most important takeaway is the weight of the source of information itself; the fact that a tech giant of such scale as Google has tied its name to such a specific timeline should prompt the blockchain community to fundamentally rethink its architecture. Regarding why the conclusions of the white paper attracted so much attention, Ziskind said: "Previous work in this area has generally been either too theoretical or too optimistic about qubit requirements. This one, it seems, fills the gap in a way that should make people uneasy." Meanwhile, the main breakthrough in Google's white paper caused shock in the blockchain community: researchers demonstrated that a "cryptographically significant quantum computer" (CRQC) could achieve a 41% success rate in intercepting transactions before they are confirmed.
