/img/quantumNewV2-1451401939930.jpgExascale Trade-offs The road to an exaflops supercomputer won’t be smooth. The millivolt switch, for example, would dramatically reduce power draw. But how to make one, and when it would be ready, is anybody’s guess.

For most of the decade, experts inhigh-performance computing have had their sights set on exascale computers—supercomputers capable of performing 1 million trillion floating-point operations per second, or 1 exaflops. And we’re now at the point where one could be built, experts say, but at ridiculous cost.

The Spectacular Collapse of CryptoKitties, the First Big Blockchain Game

A cautionary tale of NFTs, Ethereum, and cryptocurrency security

Mountains and cresting waves made of cartoon cats and large green coins.

On 4 September 2018, someone known only as Rabono bought an angry cartoon cat named Dragon for 600 ether—an amount of Ethereum cryptocurrency worth about US $170,000 at the time, or $745,000 at the cryptocurrency’s value in July 2022.

It was by far the highest transaction yet for a nonfungible token (NFT), the then-new concept of a unique digital asset. And it was a headline-grabbing opportunity for CryptoKitties, the world’s first blockchain gaming hit. But the sky-high transaction obscured a more difficult truth: CryptoKitties was dying, and it had been for some time.
