‘Axie Infinity’ is back open for business following $625 million hack

After a massive $625 million hack, the cryptocurrency pay-to-earn game Axie Infinity is once again open for business. The hack took advantage of flaws in the Ronin network, an Ethereum sidechain the game’s owner, Sky Mavis, propped up to facilitate faster transactions. Surprisingly, the news today is that Axie Infinity will… continue to use Ronin, which has been revived after a few audits. In a blog post, the company described a new “circuit-breaker” system designed to flag “large, suspicious withdrawals,” withdrawal limits and human reviewers. It also promised players that a new land staking feature — which claims to allow the game’s owners of digital land to earn passive income — will be released later this week.

In March, a group of hackers pilfered nearly 173,600 Ethereum and nearly 26 million USDC (worth roughly $26 million) from the game’s network. US officials have since linked the North Korean-backed hacking group Lazarus to the heist. Last week Sky Mavis said it would begin reimbursing the victims of the hack — but didn’t account for Ethereum’s drop in value over the past three months, which means that users would only recover about a third of their losses. In all, Sky Mavis is returning $216.5 million in funds to its users.

Moving forward, Axie Infinity players are warned not to send funds directly to Ronin Bridge’s smart contract address. “The Ronin Bridge should only be accessed and used for deposits/withdrawals through the Ronin Bridge UI. Any funds sent directly to the Ronin Bridge’s contract addresses will be permanently lost,” wrote the company in its post.

Esports.net recently pointed out a flaw in Axie Infinity’s design — a drop in the number of players causes the value of its in-game currency to plummet. Bloomberg noted earlier this month that the game’s user base has declined by 40 percent since the hack. As of this writing, the value of AXS is at $15.30 (a drop from its high of $160.36 in July 2021) and the value of SLP is at 0.0039 (down from an all-time high of 0.364).

Apple’s mixed reality headset may feature an M2 processor

Robots learn to shape letters using Play-Doh

Humans aren’t the only ones working with Play-Doh. MIT CSAIL researchers have created a system, RoboCraft, that teaches robots how to work with the kid-friendly goo. The platform first takes the image of a shape (in this case, a letter of the alphabet) and reinterprets it as a cluster of interlocking particles. The bot then uses a physics-oriented neural network to predict how its two “fingers” can manipulate those spheres to match the desired outcome. A predictive algorithm helps the machine plan its actions.

The technology doesn’t require much time to produce usable results. It took just ten minutes of practice for an robot to perform roughly as well (and in some cases better) than humans remote-controlling the same hardware. That’s not the same as having a human shape the Play-Doh by hand, but it’s no mean feat for a machine discovering how to perform the task for the first time. Robots frequently struggle with soft objects where they tend to thrive with firm shapes.

RoboCraft-trained bots aren’t about to produce elaborate sculptures. The results are still imprecise, and the machine works slowly using just two fingers. The team is already developing a method of making dumplings, though, and plans to teach robots to use additional tools (such as a rolling pin) to prep the food.

The CSAIL scientists already have an idea of where the technology might be deployed. Kitchen robots could take over more responsibilities, while artistic automatons might create pottery. Eventually, technology like this could help the elderly and people with mobility issues by taking over household duties that require subtle motor skills.

Amazon is opening a center for quantum networking research

Several major companies are working on quantum computing projects, including IBM and Google. Amazon is also in the mix. The company opened the AWS Center for Quantum Computing last year and has offered quantum computing via Amazon Web Services since 2019. It’s expanding that work to what it says is an essential aspect of helping quantum tech reach its full potential: quantum networking. As such, the company has announced the AWS Center for Quantum Networking (CQN).

As with quantum computing, it’s early days for quantum networking. It will likely take several more years before researchers start getting the most out of quantum tech. However, Amazon has more resources than most to invest in the field.

Amazon notes that quantum networks will be able to connect quantum devices using single photons rather than laser beams (which are utilized in modern optical communications). However, along with enabling certain capabilities of quantum networks, there are some hurdles to overcome when it comes to using a single photon. Quantum mechanics limits the amplification of a single photon, which restricts the range of a network. “Also, the weakness of single photons complicates interfacing them with today’s quantum computing devices,” CQN research scientists Denis Sukachev and Mihir Bhaskar wrote in a blog post.

Researchers at the center will work on new technologies, such as quantum repeaters and transducers, to allow for the creation of global quantum networks. They’ll develop hardware, software and apps for quantum networks.

Among the potential applications of quantum networking is “enabling global communications protected by quantum key distribution with privacy and security levels not achievable using conventional encryption techniques,” Sukachev and Bhaskar wrote. “Quantum networks will also provide powerful and secure cloud quantum servers by connecting together and amplifying the capabilities of individual quantum processors.”

UK regulator plans to launch probe into Google’s and Apple’s mobile duopoly

The UK’s Competition and Markets Authority (CMA) has concluded that Google and Apple “hold all the cards” when it comes to mobile phones a year after taking a closer look at their “duopoly.” It’s now consulting on the launch of a market investigation into the tech giants’ market power in mobile browsers, as well as into Apple’s cloud gaming restrictions. In addition, the CMA has launched a separate investigation into Google’s Play Store rules — the one that requires certain app developers to use the tech giant’s payment system for in-app purchases, in particular. 

The CMA has concluded after its year-long study that the tech giants do indeed exhibit an “effective duopoly” on mobile ecosystems. A total of 97 percent of all mobile web browsing in the UK is powered by Apple’s and Google’s browser engines. iPhones and Android devices typically come with Safari and Chrome pre-installed, which means their browsers have the advantage from the start. Further, Apple requires developers to make sure their iOS and iPadOS apps are using its WebKit engine to browse the web. That limits the incentives Apple may have to invest in Safari, the CMA said.

The agency also pointed out that Apple enforces policies that prevent cloud gaming apps from being available to download from its App Store. Under its rules, cloud gaming services would have to individually submit each playable game for review and approval if they want to be listed. The company eventually carved out an exception, but only to make services like Xbox Cloud Gaming available on iOS devices through a browser.

In its announcement, the CMA explained that the lack of intervention would allow the tech giants to maintain and even strengthen their hold not just over mobile browsers, but also over mobile operating systems and app stores. Their duopoly could stifle competition and limit incentives for individuals and other companies to innovate and develop new products and technologies for those markets.
