That day may be closer than they think, but even with the speed of today’s supercomputers, only quantum computers can have that capability.

Last week, researchers at Lawrence Livermore National Laboratory announced that the latest El Capitan supercomputer can perform 2.79 trillion calculations per second, making it the fastest computer in the world.

To understand the value, it’s 2.79 followed by 15 zeros.

To compare that to what El Capitan can do in 1 second, over 100 million of the latest iPhones would have to perform 1 calculation

at a time, Jeremy Thomas of the Lawrence Livermore National Laboratory told Decrypt. It’s a stack of phones over 5 miles high.

The results were presented at the annual SC Conference, an international conference dedicated to high-performance computing, held Monday in Atlanta, Georgia. El Capitan was ranked 500th on the list of 500 most powerful supercomputers in the world, which is compiled twice a year by the project top 1.

At Livermore National Laboratory in Livermore, California, together with Hewlett-Packard Company, AMD, and the Ministry of Energy to develop El Capitan-systems to produce high performance, high-performance, high-performance, high-performance, high-performance, high-performance, high-performance, high-performance, high-performance, high-performance, high-performance, high-performance, high-performance, high-performance, high-performance, high-performance, high-performance, high-performance For example, a computer like El Capitan performs 5.4 trillion operations per second, which is 2.7 million times faster than a typical home computer.

Using a telephone analogy, Thomas calculated that to do what El Capitan can do in 1 second would require more than 8 billion people working simultaneously for 80 years.

The power of El Capitan raises questions about its potential impact on the blockchain industry, where security relies heavily on strong encryption. However, blockchain and cryptocurrency experts say these fears are unfounded.

“They need to sort through all possible private keys, Yannick Schrade, CEO and co-founder of Arcium, said of the Decrypt program. For example, if a private key is 256 bits long, an attacker would have to check all possible 256-bit keys if he tried to spoof a transaction.

Modern artificial intelligence models have hidden functions that suddenly and consistently appear during the learning process, but according to a new study conducted by Harvard and the University of Michigan, these functions remain hidden until they are used in a specific way. The study analyzes how AI systems learn concepts such as color and size and shows that models often acquire these skills much earlier than standard tests suggest, which has serious implications for AI safety and development. “Our results show that…

Swiss company Arcium, launched in 2022, aims to create a decentralized supercomputing network that will allow developers to securely and efficiently perform encrypted computations on the blockchain.

According to Schreid, supercomputers such as El Capitan, even with the ability to perform 2,700 trillion operations per second, take 256 billion years to brute force 100-bit private keys because of the computational asymmetry inherent in the cryptography used, such as the elliptic curve cryptography used in blockchains such as Bitcoin, Ethereum and Solana.
