first_imgRamgeet wins twin feature at Turf Paradise PHOENIX, Arizona (CMC): Jamaican jockey Andrew Ramgeet made all the headlines here on Saturday when he won both feature races on the day’s eight-race card at Turf Paradise. Ramgeet captured the US$35,000 Queen of the Green Stakes with 22-1 outsider Hip Ninety Three in race three, before returning to steal victory in the Walter R Cluer Memorial Stakes, also worth $35,000, with favourite Az Ridge, in race seven. The victory aboard Az Ridge was made even more memorable after the rider survived two moments of misfortune to battle to the wire and beat the three-year-olds and upward by a neck in a tight three-horse finish. Going off as the punters’ 7-5 choice in a mile trip, Ramgeet and the six-year-old bay gelding stumbled at the start to trail the field as 20-1 outsider Bourbon Sense posted the early fractions while chased by Ride Hard Kowboy. However, Az Ridge made good progress and entered the stretch in contention with the front three. Ramgeet then rallied the gelding and despite losing his whip at the sixteenth pole, still managed to outlast his rivals. Rosberg wins season-ender ABU DHABI, United Arab Emirates (CMC): Lewis Hamilton trailed home Mercedes teammate Nico Rosberg for the third straight time, as the German controlled the race from start to finish to win the season-ending Abu Dhabi Grand Prix yesterday. Starting on pole, Rosberg made no mistakes at Yas Marina to coast to his sixth win of the season and finish second in the overall championship with 322 points. Hamilton had wrapped up the title with three races to go when he captured the United States Grand Prix in Texas back in October, to clinch his third World title and second consecutive. The Brit, whose paternal grandparents are Grenadian, finished on 381 points and said afterward he was glad the season was finally over. “It’s been a good year. I’m happy. I’m happy it’s over, for sure. So now we can really enjoy,” Hamilton told media. “I really have to take my hat off to this team who once again did an amazing job in building this car.” Ferrari’s Kimi Raikkonen was third, while his teammate, former World champion Sebatien Vettel, clinched third spot overall in the championship with 278 points.last_img read more

To bring the idea to fruition next year, the social network has created a new subsidiary called Calibra that will offer digital wallets designed to hold, send, and receive the virtual coins.But just how well will Libra, and Facebook’s Calibra, protect people’s privacy? And should consumers be worried about using the new services?Facebook knows it has lost trust with consumers over its repeated snafus, and is therefore being careful with what it says about its new products. In short, the company is pleading: Trust us this time.“There will be separation of data,” David Marcus, Facebook’s lead blockchain executive, stressed to Fortune. “People don’t want their financial data and social data commingled.”Let’s take a look at the reality of the situation.Balancing the scalesPeople already familiar with Bitcoin and Ethereum will recognize the basis for Libra’s blockchain, the underlying accounting ledger that tallies virtual wealth across a distributed network of computers. Libra’s version, built on a new open source codebase, has the same privacy properties as those predecessors, says Kevin Weil, Calibra’s vice president of product.At a technical level, this means the Libra blockchain will rely on pseudonyms in the form of strings of letters and numbers that represent people’s identities. To drill down deeper: These strings are known as a public and private key pairs. People can use the public key as a shareable destination address for money, while the private key is a secret, like a passcode, that people can use to sign and validate transactions as authentic.Libra’s blockchain does not offer anonymity. The setup is not as privacy-protective as other specialized cryptocurrencies, such as Zcash and Monero, strive to be. Zcash includes an advanced cryptographic option to keep people’s financial details—including their pseudonymous identities even—hidden from public view. Monero, meanwhile, mixes and scrambles details related to people’s transactions to obscure them.But security experts warn that no known privacy system is bullet-proof.Does this mean that Facebook or others could inspect the blockchain, or public ledger, at the system’s core, and thus see everyone’s payment histories? Answering this question requires some subtlety.Calibrating CalibraIn a paper released Tuesday morning, Facebook assures people that its products will not source account information or financial data from Calibra “without customer consent.” Neither will it share the any of this information with third parties, except in cases involving potential fraud, criminal activity, legal compliance, or product performance. (Facebook must also share certain information with vendors and payment processors to make sure people get paid.) Any shared information “will not be used to improve ad targeting” without permission, the document specifies.If Facebook’s legalese is to be believed, then the default setting for Calibra will require people to opt in for data-sharing. The wallet service will be available as a standalone app on iOS and Android, but also as a service integrated with WhatsApp and Facebook Messenger. Presumably, if someone were to explicitly agree to link their Calibra account to another Facebook product—importing their WhatsApp contacts, say—then this would open up the data pipe for sharing.This document is not a binding privacy policy, of course. Terms of service will come later, once the product debuts, presumably in 2020.Settling upCalibra is what cryptocurrency professionals call a “layer two” technology. This means that Facebook will settle accounts on its own internal ledgers and later record the end results, in aggregate, on the wider Libra blockchain. This affords an extra level of protection. Outsiders should be generally unable to inspect individuals’ payments, transaction timestamps, and aliases. Instead, they will see bigger, batched moves reflecting the state of Calibra’s systems. This helps prevent attackers from untangling the data and figuring out people’s real identities and purchasing proclivities.People who use Calibra will have to trust Facebook’s internal firewalls and security measures, of course. And there’s a lot of data here that hackers and snoops might like to access. In order to abide by standard “know-your-customer” and “anti-money laundering” laws, Calibra will have to verify people’s identities through a thorough process, collecting government-issued IDs and other personal details and documentation. It will be incumbent upon Calibra to keep this data confidential and secure.Placating the FaceboycottersFor people who still don’t trust Facebook, even after all the company’s assurances, they may opt to use another wallet provider.Because the Libra codebase is open source, any other company or ideologically motivated set of programmers will be able to create their own wallets, managed however they please and bearing whatever properties they wish. Libra’s blockchain and codebase is slated to be governed by a Swiss nonprofit, the Libra Association, which includes corporate giants such as Visa, Mastercard, PayPal, and Uber. One might expect Coinbase, PayPal’s Venmo, and others to develop their own virtual wallets, or add Libra integrations, before the cryptocurrency’s expected premiere in 2020.Facebook, for its part, doesn’t plan on tweaking regulators as Bitcoin’s most fervent supporters have. “A new form of digital currency is bound to happen whether we do that or not,” Facebook’s Marcus says. “Either it happens in a way that’s antagonistic to governments and banks, or it can be done by a number of trusted organizations that will definitely play by the rules.”That “definitely” will be a tough sell for some consumers who are fed up with Facebook’s litany of security missteps and privacy abuses. But for other people, the convenience of Facebook’s coming cryptocurrency business, entwined with its super popular chat apps, may lure them yet.More must-read stories from Fortune:—Project Libra: Facebook’s wildly ambitious plan to bring cryptocurrency to the masses—5 things to know about Project Libra—How cord-cutting is driving big changes across the media landscape—Andreessen Horowitz’s Scott Kupor demystifies the VC funding process—To break up Facebook, here’s where the government might start—Listen to our new audio briefing, Fortune 500 DailyFollow Fortune on Flipboard to stay up-to-date on the latest news and analysis.You May Like by Ultimate Software Sponsored Content HealthFormer GE CEO Jeff Immelt: To Combat Costs, CEOs Should Run Health Care Like a BusinessHealthFor Edie Falco, an ‘Attitude of Gratitude’ After Surviving Breast CancerLeadershipGhosn Back, Tesla Drop, Boeing Report: CEO Daily for April 4, 2019AutosElon Musk’s Plan to Boost Tesla Sales Is Dealt a SetbackMPWJoe Biden, Netflix Pregnancy Lawsuit, Lesley McSpadden: Broadsheet April 4last_img read more
