The Coinmine One is a box that mines crypto at home

For $799 you can start mining cryptocurrencies in your home, a feat that previously either required a massive box costing thousands of dollars or, if you didn’t actually want to make any money, a Raspberry Pi. The Coinmine One, created by Farbood Nivi, soundly hits the sweet spot between actual mining and experimentation.

The box is about as big as a gaming console and runs a custom OS called MineOS. The system lets you pick a cryptocurrency to mine – Monero, for example, as the system isn’t very good with mature, ASIC-dependent currencies like BTC – and then runs it on the built in CPU and GPU. The machine contains a Intel Celeron Processor J Series processor and a AMD Radeon RX570 graphics card for mining. It also has a 1 TB drive to hold the massive blockchains required to manage these currencies.

The box mines Ethereum at 29 Mh/s and Monero at 800 h/s – acceptable numbers for an entry level miner like this one. You can upgrade it to support new coins, allowing you to get in on the ground floor of whatever weird thing crypto folks create tomorrow.

I saw the Coinmine in Brooklyn and it looks nice. It’s a cleverly-made piece of consumer tech that brings the mystery of crypto mining to the average user. Nivi doesn’t see this as a profit-making machine. Instead, it is a tool to help crypto experimenters try to mine new currencies and run a full node on the network. That doesn’t mean you can’t get Lambo with this thing, but expect Lambo to take a long, long time.

The device ships next month to hungry miners world-wide. It’s a fascinating move for the average user to experience the thrills and spills of the recent crypto bust.

Blockchain media startup Civil is issuing full refunds to all buyers of its cryptocurrency

Many doubted The Civil Media Company‘s ambitious plan to sell $8 million worth of its cryptocurrency, called CVL. 

The skeptics, as it turns out, were right. Civil’s initial coin offering, meant to fund the company’s effort to create a new economy for journalism using the blockchain, failed to attract sufficient interest. The company announced today that it would provide refunds to all CVL token buyers by October 29.

Civil’s goal was to sell 34 million CVL tokens for between $8 million and $24 million. The sale began on September 18 and concluded yesterday. Ultimately, 1,012 buyers purchased $1,435,491 worth of CVL tokens. A spokesperson for Civil told TechCrunch an additional 1,738 buyers successfully registered for the sale, but never completed their transaction.

Civil isn’t giving up. The company says “a new, much simpler token sale is in the works,” details of which will be shared soon. Once those new tokens are distributed, Civil will launch three new features: a blockchain-publishing plugin for WordPress, a community governance application called The Civil Registry and a developer tool for non-blockchain developers to build apps on Civil.

ConsenSys, a blockchain venture studio that invested $5 million in Civil last fall, has agreed to purchase $3.5 million worth of those new tokens. The purchase is not an equity; all capital from the token sale is committed to the Civil Foundation, an independent nonprofit initially funded by Civil that funds grants to the newsrooms in Civil’s network.

In a blog post today, Civil chief executive officer Matthew Iles wrote that the token sale failure was a disappointment but not a shock. Days prior, he’d authored a separate post where he admitted things weren’t looking good.

“This isn’t how we saw this going,” Iles wrote. “The numbers will show clearly enough that we are not where we wanted to be at this point in the sale when we started out. But one thing we want to say at the top is that until the clock strikes midnight on Monday, we are still working nonstop on the goal of making our soft cap of $8 million.”

A recent Wall Street Journal report claimed Civil had reached out to The New York Times, The Washington Post, Dow Jones and Axios, among others, but failed to incite interest in its token.

Separate from its token sale, Civil has inked strategic partnerships with media companies like the Associated Press and Forbes, both of which confirmed to TechCrunch today that the failed token sale doesn’t impact their partnerships with Civil. 

Forbes became the first major media brand to test Civil’s technology when it announced earlier this month that it would experiment with publishing content to the Civil platform. As for the AP, it granted the newsrooms in Civil’s network licenses to its content. 

Civil, of course, isn’t the only blockchain startup targeting journalism. Nwzer, Userfeeds, Factmata and Po.et, which was founded by Jarrod Dicker, a former vice president at The Washington Post, are all trying their hand at bringing the new technology to the content industry.

Which, if any, will actually find success in the complicated space, is the question.

SpankChain spanked

SpankChain, a cryptocurrency aimed at decentralized sex cams, has announced that a hacker stole about $38,000 from their payment channel thanks to a broken smart contract. They wrote:

At 6pm PST Saturday, an unknown attacker drained 165.38 ETH (~$38,000) from our payment channel smart contract which also resulted in $4,000 worth of BOOTY on the contract becoming immobilized. Of the stolen/immobilized ETH/BOOTY, 34.99 ETH (~$8,000) and 1271.88 BOOTY belongs to users (~$9,300 total), and the rest belonged to SpankChain.

Our immediate priority has been to provide complete reimbursements to all users who lost funds. We are preparing an ETH airdrop to cover all $9,300 worth of ETH and BOOTY that belonged to users. Funds will be sent directly to users’ SpankPay accounts, and will be available as soon as we reboot Spank.Live.

The hacker used a ‘reentrancy’ bug in which the user calls the same transfer multiple times, draining a little Ethereum each time. The bug is the same one that previously affected the DAO.

The company pointed out that a security audit on their smart contract would have cost $50,000, a bit more than the amount lost. “As we move forward and grow, we will be stepping up our security practices, and making sure to get multiple internal audits for any smart contract code we publish, as well as at least one professional external audit,” they wrote.

I’ve reached out to the company for clarification but in short it seems the spanker has become the spankee.

Peep the future of distributed ledgers with the leaders of Hyperledger, Parity Technologies and Tradeshift

As cryptocurrencies emerge from the speculative bloodletting of the past months, believers in the promise of distributed ledger technologies for business and consumer applications are casting about for what comes next.

On our stage at Disrupt San Francisco we’ll be welcoming some of the leading thinkers in how distributed ledgers can create an entirely new architecture for computing and new processes for almost every conceivable transaction framework.

For Brian Behlendorf, the executive director of Hyperledger, distributed ledger technologies represent a powerful path for the future of networked computing — no matter the underlying technology.  That’s why Behlendorf –through the Linux Foundation — is investing resources in ensuring that viable open source distributed ledger projects are supported and coming to market for any number of applications for businesses and consumers.

One of the leading lights of the internet revolution, Behlendorf’s career shaping the future of the networked world began in 1993 when he co-founded Organic Inc. — the first business dedicated to building commercial websites. Going on to become one of the foundational architects of the Apache http protocol, Behlendorf has served as the chief technology officer of the World Economic Forum and as an executive director for the technology investment fund, Mithril Capital.

Meanwhile, Parity Technologies is attempting to ensure that businesses don’t need to worry about the underlying technologies at all. Selling a suite of services that are all enabled by distributed ledger technologies and cryptographic computing, Jutta Steiner is giving businesses a way through the maze of competing protocols with a service that can enable the creation and adoption of distributed apps for businesses.

“We see it as a way for people to build blockchains that fulfill their particular needs,” Steiner told our own Samantha Stein at our Blockchain event earlier this year in Zug. “One of the challenges we’re addressing in this is to come up with a scalable framework.”

Before Parity, Steiner was responsible for security and partner integration within the Ethereum Foundation when the public blockchain first launched in 2015. Steiner also co-founded Project Provenance — a London based start-up that employs blockchain technology to make supply chains more transparent.

Supply chains are at the heart of Tradeshift’s offerings — and the company is hoping that distributed ledgers will be too. That’s why the company created Tradeshift Frontiers, an innovation lab and incubator that will focus on transforming supply chains through emerging technologies, such as distributed ledgers, artificial intelligence and the Internet of Things.

“The use cases we’re working through Frontiers cover a very wide variety of themes, including supply chain financing, asset liquidity, and supply chain transparency,” said Gert Sylvest, co-founder and GM of Tradeshift Frontiers, at the time. “There is so much more potential than just cryptocurrencies.”

That potential will be one of the things that Sylvest, Steiner, and Behlendorf discuss. We’ll hope you’ll be in the audience to listen.

Disrupt SF will take place in San Francisco’s Moscone Center West from September 5 to 7. The full agenda is here, and you can still buy tickets right here.

The SEC creates an educational ‘token’ to stop scammers

“Travel is expensive, but we are at the cusp of a revolution that will democratize travel and leisure for everyone,” reads the breathless whitepaper for HoweyCoins. “The Internet was the first part of the revolution. The other part is blockchain technology and cryptocurrencies.”

“I’m all about HoweyCoins – this thing is going to pop at the top!” writes @boxingchamp1934, an official celebrity backer of the token. The website is full of beautiful beaches, features a handsome team of international men and women and the technology is nowhere to be seen, buried under a sea of excitement. The whitepaper is complete and well-written, focusing on the upside that is to come. Riches await if you invest in HoweyCoin, the latest ICO opportunity from trusted folks.

Or do they?

They don’t. All that breathless optimism is a site created by US Securities Exchange Commission to warn investors of scams and issues associated with token sales. The site features all the trademarks of a scammy security token, including tiered pre-sale pricing and an urgent countdown clock.

The site features a number of red flags that the SEC encourages users to watch out for, including, most importantly, claims that tokens can only go up in value. They write:

Every investment carries some degree of risk, which is reflected in the rate of return you can expect to receive. High returns entail high risks, possibly including a total loss on the investments. Most fraudsters spend a lot of time trying to convince investors that extremely high returns are “guaranteed” or “can’t miss.”

The SEC also notes that “it is never a good idea to make an investment decision just because someone famous says a product or service is a good investment,” and that it is never a good idea to invest with a credit card.

They also warn against pump and dump language found on many ICO pages. “Our past two pumps have doubled value for the period immediately after the pump for returns of over 225%,” wrote the HoweyCoins “creators,” a giant no-no in the world of investing.

You can read the rest of the red flags here.

While the site is fairly comical, it is sufficiently complete and would fool the casual observer. The SEC also posted a real-looking whitepaper that makes it clear that anyone can string together a few buzzwords and write a passable investment prospectus. That this is now a service available to anyone — for a price — makes things even scarier.

The site is part of the SEC’s outreach efforts to help investors understand ICOs.

“Strong investor protection is part of what makes American markets so strong…and striking the balance, [between innovation and investor protection] is very important,” said Chief of the SEC Cyber Unit Robert Cohen at Consensus this week. During the same panel the SEC claimed its doors were always open for questions.

Ultimately there is little separating the scams from the real token sales. This is a problem. The SEC is framing this problem in their own way based on decades of dealing with pink sheet pump and dumps and bogus get-rich-quick schemes. While HoweyCoins may not be real, there are plenty of scammers out there, and at least something like this bogus website makes it easier to spot the warning signs.
