EOS Security Vulnerabilities: David Moss of Block.one Responds to 360 Report

The claims made by Qihoo 360’s Vulcan team regarding EOS security may be exaggerated and unsupported
EOS Security Vulnerabilities: David Moss of Block.one Responds to 360 Report

The opinions expressed in this article are strictly David Moss’s own and not to be interpreted as speaking on the behalf of Block.one or any other entity.

As the planned June release of EOSIO 1.0 approaches, expectations and tensions are heating up.

Most recently, Monday’s news of possible security vulnerabilities detected by Chinese Internet security giant Qihoo 360 elicited strong responses from EOS supporters and opponents alike.

According to the Weibo post published by Qihoo 360 on Monday, high-risk security vulnerabilities in the EOS platform could enable remote attacks through the deployment of arbitrary code and insertion of malicious smart contracts into new blocks.

Such a security breach may give the attacker full control of the network’s nodes, affecting thousands of computers and accounts.

Past ICO Review: EOS, an ICO Success Story

The discovery of the security issues was made by Qihoo 360’s Vulcan team, and the wording of the report seems to suggest close collaboration by the Chinese security company with EOS to resolve these issues ahead of the EOSIO launch, but this may not be the case.

David Moss, senior vice president of Tech Operations at Block.one, the open source software publisher responsible for the EOSIO launch, provided comment to CryptoComes on the Vulcan findings

“The allegations were greatly exaggerated by Vulcan 360, as was their involvement with Block.one. They are only to want publicity for themselves and to create the impression they are working with Block.one. They are not. They also have no documentation to back up any claim they made.”

As always, investors and developers are responsible for doing due diligence when it comes to platform security.

The crypto media environment is as susceptible as mainstream media, if not more, to conflicting reports, sensationalism and news cycles used as marketing tools.

The release of EOSIO software has been one of the most eagerly expected events in the crypto community and the next few weeks are certain to put increased pressure on the EOS team to provide commentary on arising questions.

CoinSpectator: A Powerful News Aggregator or a Ream of Nonsense?

News is a powerful tool in the cryptocurrency space as speculation can drive and drop the market, so is CoinSpectator a good place to go?
CoinSpectator: A Powerful News Aggregator or a Ream of Nonsense?

News, in relation to economic markets and assets, has always been a powerful tool. The goings on outside of the market always has a big role to play in the way the graphs will move, be it stocks, bonds, assets or companies.

In the cryptocurrency space it is just as important, if not even more, as the speculative nature of cryptocurrencies sees the market swing violently on any news that can be positive or negative to the space.

For traders, interested parties, and those involved in the cryptocurrency space in general, it is necessary to have one’s finger on the pulse of what is happening. And this is where news aggregators come in.

CoinSpectator is one such news aggregator, and it is important to gauge whether it is a good one, or rather just a revolving ream of wasted information.

News aggregation?

Because news can come from many different sources, and be reported on in many different lights and angles, news aggregators help give objectivity to the information being put out.

It is a list of different publication that are reporting on the news as it happens, and being fed to one site for an individual to follow as it happens. This often leads to a wave of different sites posting about the same piece of news as an aggregator complies with them.


:- The good

A first look at CoinSpectator and it is all business. It is a dark background with a ream of news running down the middle with some useful tools across a toolbar at the top- such as a filter system and a search bar. Along the right there is also an explanation of the site and a few hints. There is also a market with eight major cryptocurrencies at the bottom.

CoinSpectator: A Powerful News Aggregator or a Ream of Nonsense?

The simple design is all that is needed as one can focus in on the news and not be distracted by anything else.

It also has a voting system in which the active community can vote on the strength of a story, giving it either a thumbs up or thumbs down. This is very useful in an ecosystem that is rife with scams, as crowdsourced opinions can help guide people away from fake news.

CoinSpectator: A Powerful News Aggregator or a Ream of Nonsense?

Its filter system is also quite intuitive and can help a user decide what kind of news they are looking for. It can break down the news sources into anything from news, blogs, and projects, to videos and PR pieces.

CoinSpectator: A Powerful News Aggregator or a Ream of Nonsense?

:- The bad

Like with many aggregators, when news does hit, there will be a lot of repetition, sometimes, exact duplicates. And while this is not necessarily the fault of the aggregators, it is still annoying.

CoinSpectator: A Powerful News Aggregator or a Ream of Nonsense?

There are also a few instances where adverts and irrelevant items crop up in the news feed. And while there is nothing against advertising, it seems unnecessary to have them appear in the news timeline.

CoinSpectator: A Powerful News Aggregator or a Ream of Nonsense?


Overall, the site works well as a news aggregator, and because of its filters and dynamic search, it is easy to get a quick and comprehensive overview of the topic you are choosing.

News is still quite subjective, and while the community has a voting system, it is quite small as it stands, and is not yet fully effective- but that will likely change.

Most Profitable Cryptocurrency Miners? College Students Mining from Dorms

College dorm mining operations may be small, but they are immensely profitable due to free electricity.
Most Profitable Cryptocurrency Miners? College Students Mining from Dorms

Cryptocurrency mining is surging across college campuses in the United States, as students take advantage of free electricity provided by their dorms. One recent study put the cost of mining a single Bitcoin at $8,000, though areas with inexpensive hydroelectric power can mine a Bitcoin for about $2,000. Nothing beats a college kid in his dorm room though - because his cost basis is $0.

Free electricity

Mining requires specialized equipment, either ASICs for currencies like Bitcoin, Litecoin, and Dash, or GPUs for the likes of Ethereum and others. Beyond the cost of this equipment, a small-scale miner’s only real expense is electricity - electricity to run the mining equipment, and electricity to run the air conditioning that cools the equipment. If electricity is free, then miners only face the one-time cost of purchasing the proper equipment.

Free electricity drastically changes the cost equation in other ways, too. Industrial-scale miners that have to pay for their electricity typically spend a great deal of money investing in newer, more powerful mining equipment. As mining difficulty rises, old equipment produces less and less rewards for the same energy cost. Buying newer, more powerful miners helps restore balance to the equation. The new machines use about the same amount of electricity but are able to mine more cryptocurrency per watt of power used.

Changing the equation

Joey Dilliha at Western Kentucky University realized that if electricity was free, he didn’t need the newest and most powerful mining equipment in order to mine Bitcoin. Due to the speed of Bitcoin’s mining arms race, old, less efficient miners are sold for cheap on eBay. Dilliha found an inexpensive piece of older equipment on eBay, paying $250 for an old Antminer. Because of his free electricity (and free air conditioning), he has already paid for the rig and is turning a profit of $30 per week.

Some colleges, like Stanford, have policies against running miners in dorms. Others, like WKU, have banned the practice as a fire hazard, rather than for economic reasons. While the ethics of mining cryptocurrency on somebody else’s dime may be questionable, college kids in need of funds are sure to take advantage of any opportunity to turn a profit. It’s not surprising that they’ve figured out the free electricity loophole - college kids are smart, by definition, and financial need creates the perfect catalyst for invention.
