Monero’s [XMR] Riccardo Spagni calls Craig Wright ‘so dumb’; attacks Wright’s lawyer credentials

Published

on

Craig Wright, Chief Scientist at nChain, has been in cryptocurrency hot waters for quite some time now, with his claims of being Satoshi Nakamoto being disputed by most of the cryptoverse. The latest chapter in this episode was written when Wright filed a copyright for the Bitcoin whitepaper, something that was seen by the Twitter community as a gimmick and “just another form.”

The latest proponent to come out and attack the Bitcoin SV proponent is Riccardo Spagni, the lead developer at Monero. In his latest tweet, Spagni wrote,“PSA: Craig Wright is so dumb he made it illegal to run Bitcoin SV test net using the Bitcoin SV code when he illegally re-licensed it. He claims to be a lawyer, but fails to get something this simple correct…?”

According to the screenshot attached with the tweet, the mistake is in the hash number pointed out by Spagni. The hash does not define the algorithm, therefore a user can use any algorithm to come up with the given value. Spagni’s sentiment was shared by many members of the cryptocurrency community, with many starting a series of hashtags such as #CraigWrightissodumb. One user, Catoshi MeowMotonaut, tweeted,

“Are we playing  #CraigWrightissodumb ?

My entry “Craig Wright is so dumb that he sued a cartoon character on twitter”

This tweet was followed by a tweet from @amritha, a Bitcoin enthusiast, who added,“… and then called the owner of Twitter a criminal for liking alt-coins and was banned for life from the platform, resigned to writing articles to himself on Medium.”

The copyright registration was met with a lot of trepidation by the community, but the story received another twist after Jerry Britto, Executive Director at Coincenter, clarified that just because a copyright is filed, it does not mean that the claim becomes legitimate. Post the filing, the copyright office will proceed to check if the clauses in the copyright document were true or not and only if it comes out green, does the ‘Bitcoin creator’ title go to Craig Wright. Britto added,

“Unfortunately there is no official way to challenge a registration. If there are competing claims, the Office will just register all of them. Someone else could today also register themselves as the author of the white paper, thus inviting a suit from Wright and letting a court decide on the validity of the claim. I volunteer @petermccormack.”

New Monero Botnet Looks Like Last Year’s Outlaw Attack

Published

on

There’s another Monero mining botnet that’s targeting China. Or maybe it’s one we’ve seen before.

Bloggers steeped in the hacker-verse recently exposed a URL spreading a botnet that looks suspiciously like one unleashed by the Outlaw hacking group last year. The Outlaw outfit — a name coined by its discoverers at Trend Micro, who translated “the Romanian word haiduc, the hacking tool the group primarily uses” — is infamous for its previous release of a Perl-based shellbot that infiltrates through weaknesses in the Internet of Things.

The new attack, uncovered by Trend Micro’s honeypot security systems, has been restricted to computers based in China so far. The malware is spread through a malicious URL which bundles in a Monero-mining script and a backdoor-based exploit.

Trend Micro estimates that hackers have used crypto-jacking to mine $250,000 per month in Monero.

The Outlaw botnet uses a brute force attack and Secure Shell (SSH) exploit to give the attackers remote access over victim’s systems. A more detailed report of Outlaw’s previous attack showed that once the attackers have access, the malware executes commands to download and install the cryptocurrency miner payload. Additionally, if the malware detects cryptocurrency miners already installed on the system, it will delete them to reduce competition for system resources.

The security experts also noted that the backdoor component is also capable of launching distributed denial-of-service attacks which would allow the cybercriminals to monetize their botnet not only through mining, but by offering DDoS-for-hire services.

However, because the scripts haven’t been activated, Trend Micro believes the hackers are still in the testing and development phase. They suggest the malware may be laying dormant until future editions of the botnet are released.

This comment lead TheNextWeb to speculate whether the botnet has mined any cryptocurrency or made any successful attacks yet.

Inside Monero’s ‘Last Ditch Effort’ to Block Crypto Mining ASICs

Published

on

Developers behind the cryptocurrency monero are ramping up efforts to keep specialized mining hardware from dominating its race for rewards.

Of the coins that have a strong privacy focus, monero – launched in 2014 – possesses the largest market capitalization by far with an estimated $1.5 billion valuation. The annual mining rewards generated by the now 5-year-old blockchain total roughly $62 million, according to data site Messari.

But such rewards appear to be increasingly falling into the hands of ASIC operators, nudging out smaller, independent or hobbyist participants. To keep an even playing field, monero developers have conducted regular hard forks to stave off ASICs – but analysis suggests that this approach has proven ineffective as of late and that ASICs are keeping ahead of such efforts.

“ASIC manufacturers can make equipment far faster than we expected,” said monero contributor Justin Ehrenhofer. “It takes maybe a month for them to have chips designed and in production so they generally can still make a return on investment even within a six month period.”

Diego Salazar, another monero contributor, told CoinDesk:

“We [also] saw that this was very unsustainable. … It takes a lot to keep [hard forking] again and again for one. For two, it may decentralize mining but it centralizes in another area. It centralizes on the developers because now there’s a lot of trust in developers to keep hard forking.”

As such, monero developers are moving forward with activation of a new mining algorithm known as RandomX, designed to render ASICs non-competitive.

The new code is based off the work of Howard Chu – CTO and founder of computer software firm Symas Corporation – who also developed the database type the monero blockchain presently runs on. Four different audits of the RandomX code are now being completed for an expected code freeze date by July.

As it stands, the algorithm could go live in October.

“We’ve ultimately come to consensus in general that RandomX is what will be implemented. It’s our best shot to preserve monero as it was founded,”  said Ehrenhofer. “If this fails then monero will probably move to an ASIC-friendly algorithm.”

According to Salazar, RandomX is monero’s “last ditch effort to keep ASIC’s out.”

Putting CPUs at the fore

RandomX according to Chu is designed to be “CPU-centric.”

As opposed to application-specific integrated circuits (ASICs), central processing units (CPUs) are a type of computer hardware designed for multi-purpose use.

Calling it a “spectrum of computing power,” Salazar explained:

“On one end, where computers are a jack of all trades are the CPUs… On the other end, computers which does only one thing but extremely well are ASICs.”

CPU’s are the most widely distributed computing resource in the world, according to Chu.

“Practically everyone in the world now has a smart phone in their pocket with a CPU and memory that’s capable of mining RandomX,” highlighted Chu.

With maximum miner decentralization as the goal, Chu predicts that RandomX will preserve an advantageous lead favoring CPU miners over ASICs for at least the next three to five years.

Leaving GPUs behind

At the same time, estimates suggest the RandomX algorithm favors CPU miners over not only ASIC miners but GPU miners as well.

Graphics processing units (GPUs) are optimized for what Chu calls a “graphics workload which tends to be very sequential.”

“Data goes in at the head of the pipeline and you do some munching on it and it all spits out at the end of the pipeline,” Chu said. “The main emphasis there is fast transfers of data from the input to the output, pretty much in a straight line.”

For monero’s current mining algorithm, called CryptoNight, GPU miners take the lead over CPUs in terms of computation and energy efficiency. Originally, however, even CryptoNight was intended to boost CPU performance over other types of hardware.

“It’s really again kind of an accident of fate that [CryptoNight] turned out to work fairly well on GPUs. Nobody expected CryptoNight to be good on GPUs and it was anyways,” explained Chu. “The fact is today GPUs have so much memory and so much massive memory bandwidth that it’s not very much of an obstacle when it comes to CryptoNight, which was designed back in 2013 or so.”

Soon, with the activation of RandomX, Chu predicts CPUs to be “at least three times better than GPUs” at mining on the monero blockchain.

And while this has disgruntled “a very vocal but extremely small minority” of GPU miners, Ehrenhofer maintains that “people with GPUs can always either resell or repurpose their hardware.”

“If I have a monero ASIC, I don’t have that same economic option available,” said Ehrenhofer.

As such, despite the impact RandomX will have on not only ASIC miners but also GPU miners on the monero network, Ehrenhofer maintains:

“I’m not concerned about a community split here because RandomX is the closest algorithm that we can pick that retains a vast majority of monero’s ideals.”

Lingering concerns

Perhaps a more realistic concern in the mind of Ehrenhofer and others is the proliferation of botnets on the monero network as a result of a CPU-friendly mining algorithm like RandomX.

“The basic concern is there’s millions or hundreds of millions of computers that are out there that are poorly secured,” explained Chu. “It’s very easy for malware to invade these computers and take them over to do whatever a particular network operator wants to do.”

Such botnets, infected by malware, have always been somewhat of an issue on monero, according to Ehrenhofer.

“Monero is by far the most illicitly mined cryptocurrency at the moment and it has been for several years,” Ehrenhofer said. “RandomX does not prevent people from crypto-jacking and other nefarious versions of malware.”

Indeed, given that monero’s present mining algorithm – CryptoNight – has always favored CPU and GPU mining, Ehrenhofer notes that there are resources in place on the monero website and other related forums to help users who’s devices are impacted.

New partnerships

Even still, efforts to bootstrap RandomX have seen support from those outside of the community, particularly by other crypto projects that might make use of CPU-friendly mining algorithm.

Arweave, which raised a reported $8.7 million in an initial coin offering (ICO), is teseting RandomX.

“An ASIC-resistant proof-of-work algorithm like RandomX will further enhance our permanent, low-cost, tamper-resistant storage network,” said Sam Williams, founder and CEO at Arweave, in a press releasefrom earlier this month. “RandomX helps us ensure that power over the decentralized content policies in the Arweave network remains well distributed across many globally distributed parties.”

To this, Arweave has funded one of the four audits over the RandomX code.

Completed officially on Friday, the audit cost a reported $80,000 and was conducted by security firm Trail of Bits. Speaking to CoinDesk in an interview, Williams explained:

“It was one of our hopes going into the audit process that by helping to fund it we could do a small public service by making sure other [crypto] projects can see there is a programmatic proof-of-work algorithm that is likely ASIC-resistant in practice without fear of security.”

The other three audits totaling $130,000 that are still to be finalized by security firms Kudelski Security, X41 D-Sec, and QuarksLab were funded through crowd-sourced donations from the monero community. They are expected to wrap up by July, according to Chu.

The next step after that is an eventual launch of the algorithm on a public monero test network before a tentatively scheduled mainnet activation this October.

Risky business

For all the discussion that has gone into preparing RandomX for a mainnet implementation, Ehrenhofer maintains that the true benefits of RandomX won’t be certain until it’s live on the network.

“We don’t know if RandomX will work yet even if all the audits come back and they say your cryptography is pretty good. We don’t know in practice how things will actually turnout,” warned Ehrenhofer.

But the worst-case scenario in Ehrenhofer’s mind if the algorithm proves to be unsuccessful is a switch to an ASIC-friendly mining algorithm similar to the one currently utilized by bitcoin.

“I think if RandomX does fail and monero switches to something more ASIC-friendly, many in the bitcoin community will tell us, ‘I told you so.’” Ehrenhofer joked.

Even so, Salazar maintains that monero should have the runway to try new things and fail at them.

“Isn’t the idea to see what’s going to work best so that one day we can have a good digital, private, fungible cryptocurrency?” Salazar asked. “If monero is not but a stepping stone to get to that good currency then by all means let monero be the lost leader.”

Salazar concluded:

“The monero people are nothing if not resilient nerds that decide to take on the man. So we said, ‘You know what? Let’s give this a go, one last ditch effort.’”

Monero’s [XMR] Riccardo Spagni: Facebook, JPMorgan Chase launching their own coins is really interesting

Published

on











Riccardo Spagni, the lead maintainer of Monero [XMR], recently spoke about one of the most controversial centralized cryptocurrencies making a debut in the cryptocurrency market. In a conversation with Shannon Grinnell on Speaking of Crypto Podcast, Spagni remarked that the steps taken by JPMorgan and Facebook to launch their own digital coin were “really interesting”.

Spagni went on to explain that this step was interesting because it would reach millions, and probably even billions of people, particularly because of Facebook being one of the most popular social media platforms in the world. He added that these centralized entities would have to launch their own coins [JPM Coin and GlobalCoin] in a “highly regulated fashion.” Spagni also stated that through Facebook, people would eventually find their way to Bitcoin. He added,“[…] what I’m hoping will happen is people will be exposed to cryptocurrencies through something like Facebook and then they will become interested in it and will want something that’s a little bit more, something that gives them more control and more freedom, and then they will start like Bitcoin.”

This was followed by Spagni speaking about the mass adoption of Bitcoin and other cryptocurrencies. Fluffypony stated that he had two perspectives on the subject; mass adoption was “definitely” within grasp, considering all the main factors contributing to the adoption of crypto. Bitcoin could go on to become a “reserve currency,” instead of achieving mass adoption, he added.“I don’t know if I’m convinced that we will achieve mass adoption and instead we will achive something like Bitcoin being the global reserve currency, which is not the same thing as mass adoption.”

He further explained,“Reserve currencies are super useful and become like the underlying currency for like most of the cross border economic transaction in the planet, but it’s not the same thing as being used by a bunch of human beings to buy coffee and pay for their cab fare.”
