Ethereum a Few Years from 'Profound Decentralization': Co-Founder Lubin

  • Blockchain technology will power a monumental shift in society from a “scarcity to an abundance mindset.” These were the words of Ethereum co-founder Joseph Lubin speaking last week at the Web Summit in Lisbon, Portugal.
  • Lubin’s optimism over the growth of Ethereum is underlined by recent events that indicate that large power players are backing the blockchain to power large-scale disruptions.
  • CCN recently reported that financial giant JP Morgan Chase unveiled a plan to use Quorum, its enterprise version of the Ethereum blockchain, to tokenize gold bars.
  • Speaking recently to Financial Review, JP Morgan’s head of blockchain initiatives Umar Farooq also praised Quorum and described JP Morgan as “big believers in Ethereum,” which is a marked departure from the language used by JP Morgan CEO Jamie Dimon when referring to Bitcoin.

Juul Pledges Big Changes, but the Impact May Be Small

  • On Tuesday, e-cigarette maker Juul announced an aggressive-sounding plan to prevent kids from using its nicotine products, including stopping the sale of most flavored pods in more than 90,000 US retail stores and shutting some of its social media accounts.
  • Retail stores that comply with a set of restrictions, developed by Juul, for sales to those 21 and older can start selling the flavors again, the company said.
  • The brand grew in part because of popularity with young people, who were drawn to Juul’s sweet flavors, its presence on social media, and its discreet device, which is shaped like a flash drive.
  • Some of the more high-tech solutions mentioned in Juul’s action plan, such as a Bluetooth-connected device that would shut down as a way to restrict under age users, may even be a strategic play, says Conley.

Spectre, Meltdown researchers unveil 7 more speculative execution attacks

  • Consider, for example, the Meltdown attack (used to leak kernel data to user-mode programs on most Intel and some ARM chips, including those from Apple) and the Level 1 Terminal Fault (L1TF) attack (used to break into an SGX enclave).
  • Further Meltdown-style attacks discovered over the past year include an attempt to read a privileged system register from user code (which, again, generates an error because the access is forbidden but not before some speculation was allowed to occur); an attempt to use the processor's floating point unit when it is not presently enabled (which generates an error to say that there's no floating point unit available—operating systems trap this error and respond by enabling the floating point unit); and an attempt to write over read-only data.

  • What makes ’80s music sound like ’80s music?
  • There’s one particular sound that stands out.

No Coins for You! Michigan Bans Crypto Donations for Political Campaigns

  • In the letter signed by Michigan Secretary of State Ruth Johnson, it was stated that campaign donations may not be made in bitcoin and other cryptocurrencies because, by nature, the value of these crypto assets is not fixed, and their volatility makes it impossible to assign an exact dollar value to them in administrative terms.
  • Nevertheless, according to the letter, cryptocurrency campaign donations are banned and will remain so not only for these reasons, but because the reporting requirements do not make any allowance for multiple recordings needed to capture the various values likely to be held by crypto assets at various points in the process including date of sale to the donor, date of receipt by the candidate, and date of record on a campaign statement.

Man pleads guilty to swatting attack that led to death of Kansas man

  • Further ReadingAfter “swatting” death in Kansas, 25-year-old arrested in Los AngelesFederal prosecutors in Kansas announced Tuesday that a 25-year-old Californian has admitted that he caused a Wichita man to be killed at the hands of local police during a swatting attack late last year.

  • In that case, he had threatened bomb attacks in high schools, universities, shopping malls, and television stations.
  • The 25-year-old Californian is scheduled to be sentenced on January 30, 2019 in federal court in Wichita.

Meet Jennifer Tejada, the secret weapon of one of Silicon Valley's fastest-growing enterprise software startups

  • Another reason you’re likely to start hearing more about PagerDuty is its CEO of three years, Jennifer Tejada, who is rare in the world of enterprise startups because of her gender but whose marketing background makes her even more of an anomaly — and an asset.
  • In a world that’s going digital fast, Tejada knows PagerDuty can appeal to a far wider array of customers by selling them a product they can understand.
  • She’s instilling that same ethos at PagerDuty, which was founded in 2009 to help businesses monitor their tech stacks, manage disruptions and alert engineers before things catch on fire but, under Tejada’s watch, is evolving into a service that flags opportunities for its customers, too.
  • The example is a bit analogous to what Tejada herself brings to the table, which includes strong people skills (she’s very funny) and a knack for understanding what consumers want to hear, but also a deep understanding of financing and enterprise software.

Private by Design: How we built Firefox Sync – Mozilla Hacks - the Web developer blog

  • We developed Firefox Sync to be as easy to use as possible, so we designed it from the ground up to derive an authentication token and an encryption key – and we never see the passphrase or the encryption key.
  • Where does it go?” With the Firefox Sync design, you enter a passphrase of your choosing and it is used to derive an encryption key that never leaves your computer.
  • As noted above, Chrome implements Option 1 by default, which means unless you change the settings before you enable sync, Google will see all of your browsing history and other data, and use it to market services to you.
  • This is a nuanced security trade-off: having less information about the user is always desirable… The downside is that Brave can’t allow you to detect when a new device begins receiving your sync data or allow you to deauthorize it.

Roivant Sciences, a four-year-old biotech holding company, just raised $200 million in fresh funding at a whopping $7 billion valuation

  • Roivant’s newest financing event: a $200 million raise at a post-money valuation of $7 billion, led by NovaQuest Capital Management, which is an investor in two of Roivant’s companies; RTW Investments, a young investment firm focused on biopharma; and an unnamed “large U.S. insurance company,” according to a company spokesman.
  • The round follows a $1.1 billion round led last year by SoftBank’s Vision Fund, which Roivant now says was closed at a post-money valuation of $5.6 million, though it didn’t necessarily look like money well spent at the time.
  • To wit, roughly one week after the financing closed last August, Axovant Sciences, one of Roivant’s companies, received news that its much-hyped, experimental Alzheimer’s drug, intepirdine, doesn’t work.

Waymo CEO Says Alphabet Unit Plans to Launch Driverless Car Service

  • -- The head of Alphabet Inc.'s Waymo unit said it plans to launch its first commercial self-driving car service in the next two months and expects businesses to be among its biggest customers.
  • Speaking at The Wall Street Journal's WSJ Tech D.Live conference on Tuesday, Waymo's John Krafcik said the new service will charge individual passengers for rides as well as businesses, such as Walmart Inc., who want to pay to shuttle their customers to stores.
  • Waymo has said it plans to launch a self-driving ride service in 2018 and earlier this year announced deals to buy thousands of vehicles in coming years from Fiat Chrysler Automobiles NV and Tata Motors Inc.'s Jaguar Land Rover to expand its fleet.
  • Last year, Waymo began testing its self-driving vans with nonemployees in Chandler, Ariz., through its so-called Early Rider program to learn how potential customers might use and interact with the service.
