Bitcoin could be hacked by new quantum supercomputers

Published

on

Mark Webber of the University of Sussex, UK, and his colleagues studied how powerful a quantum computer would be needed to crack bitcoin in terms of the number of qubits, or quantum bits equivalent to conventional computational bits.

Every bitcoin transaction must be “confirmed” by a network of miners before it can be added to the blockchain. Each transaction is assigned a cryptographic key during this confirmation process, and cracking the key will allow you to become the owner of those bitcoins.

Transactions are declared and a key is associated with this transaction. There is a finite window of time during which this key is vulnerable, and it varies, but it is usually from 10 minutes to an hour, maybe a day.

Webber’s team calculated that it would take a quantum computer with 1.9 billion qubits to break the bitcoin encryption in 10 minutes, and a machine with 317 million qubits to break in an hour. Even taking into account a whole day, this figure drops to only 13 million qubits.

This is encouraging news for bitcoin holders because IBM’s top quantum computer only has 127 qubits, so quantum computers need to become a million times more powerful to threaten the cryptocurrency. And this, according to Webber, is unlikely to happen within the next decade.

The GeForce RTX 3050 can now also be almost fully used for Ethereum mining. Nvidia LHR v3 security cracked 90%

The GeForce RTX 3050 can now also be almost fully

A couple of weeks ago, the LHR protection in Nvidia graphics cards was cracked, which allowed everyone to use accelerators for Ethereum mining at full capacity again. But in fact, then the protection of LHR v2 was cracked, but not LHR v3.

The GeForce RTX 3050 can now also be almost fully used for Ethereum mining.  Nvidia LHR v3 security cracked 90%

The LHR v3 version is present in Nvidia’s latest releases: RTX 3050 and RTX 3080 12GB. And it is still not completely hacked, but now the NiceHash miner is able to use 90% of the performance of these cards when mining cryptocurrency. It’s not a complete hack yet, but it’s getting very close.

Fortunately, at the moment the cryptocurrency market is in a state of decline, so it hardly makes any sense to buy the same RTX 3050 for mining, which means that gamers need not worry for now.

By the way, a large article has been published on our website with an analysis of methods for cracking Nvidia protection.

Nvidia lost. LHR mining protection is also hacked under Linux. This was done by NBMiner developers

Nvidia lost LHR mining protection is also hacked under

Two days have passed since the NiceHash developers cracked the Nvidia LHR protection, as the NBMiner team also pleased their users with the same news. Only this time we are talking about software for Linux.

Thus, Nvidia’s protection completely fell for both Windows and Linux. Unfortunately, both programs are closed source, so it’s not clear what mechanisms the developers used to hack.

Whether the loss of Nvidia will affect the availability and prices of video cards is still difficult to say. At the moment, the cryptocurrency market continues to fall, but sooner or later it will turn around, and gamers may again face shortages and overpriced graphics cards.

Xiaomi has released a profitable set of security camera and

Xiaomi has introduced a new kit with an outdoor video surveillance camera and a smart door lock, which includes Mi Outdoor camera and Mi Smart Door Lock 1S.

The bundle is priced at around $237, which is a great deal as these devices cost $20 more individually.

Mi Smart Door Lock 1S supports 7 unlocking methods, including fingerprint, password, temporary password, Bluetooth, HomeKit, NFC or regular key unlock. Compared to the first generation, the new lock supports both the Mijia app and Apple HomeKit.

As for the rechargeable version of Xiaomi Outdoor Camera, this is Xiaomi’s first outdoor wireless camera. It has an independent design and can be installed without connecting the mains cable or power cable. It has a wide viewing angle of 130°, 1080p resolution and supports WDR technology.

In addition, the battery version of the Xiaomi Outdoor Camera offers night vision up to 7 meters and people detection function. It is IP65 rated and has a long battery life of up to 90 days.
