A public1, permanent2, append-only3distributed4ledger5. Once hailed as unhackable, blockchains are now getting hacked. Early last month, the security team at Coinbase noticed something strange going on in Ethereum Classic, one of the cryptocurrencies people can buy and sell using Coinbase’s popular exchange platform.
Its blockchain, the history of all its transactions, was under attack. An attacker had somehow gained control of more than half of the network’s computing power and was using it to rewrite the transaction history. There's No Good Reason to Trust Blockchain Technology.

The view of two experts. Michael Lee and Antoine Martin Bitcoin and other “cryptocurrencies” have been much in the news lately, in part because of their wild gyrations in value.
Michael Lee and Antoine Martin, economists in the New York Fed’s Money and Payment Studies function, have been following cryptocurrencies and agreed to answer some questions about digital money.

Token Daily - Crypto news, launches, and discussions. Researchers find that one person likely drove Bitcoin from $150 to $1,000 – TechCrunch. Researchers Neil Gandal, JT Hamrick, Tyler Moore, and Tali Oberman have written a fascinating paper on Bitcoin price manipulation.
Entitled “Price Manipulation in the Bitcoin Ecosystem” and appearing in the recent issue of the Journal of Monetary Economics the paper describes to what degree the Bitcoin ecosystem is controlled by bad actors. To many it’s been obvious that the Bitcoin markets are, at the very least, being manipulated by one or two big players. “This paper identifies and analyzes the impact of suspicious trading activity on the Mt.
Gox Bitcoin currency exchange, in which approximately 600,000 bitcoins (BTC) valued at $188 million were fraudulently acquired,” the researchers wrote. “During both periods, the USD-BTC exchange rate rose by an average of four percent on days when suspicious trades took place, compared to a slight decline on days without suspicious activity. The publicly reported trading volume at Mt. La police danoise arrête un narcotrafiquant grâce au traçage de ses Bitcoins - Politique. Au Danemark, la police vient de recourir pour la deuxième fois au traçage d'échanges en Bitcoins afin de confondre un suspect.
Ces investigations montrent que la monnaie cryptographie ne garantit pas aux criminels qui l'utilisent une couverture totale de leurs activités illicites. Pas d’autorité centrale, un logiciel open source et des transactions de pair à pair : il serait simple (voire simpliste) de penser que les caractéristiques du Bitcoin en font une monnaie intraçable, garantissant un parfait anonymat… la monnaie que tous les criminels du monde attendaient pour agir en ligne sans craindre d’être pris en flagrant délit.

Blockchain technology, cryptocurrencies, and token sales are all the rage right now. In the 5+ years I’ve been working in the VC industry, this is by and large the fastest I’ve seen any area of technology take off in terms of new company (or project) formation. How Apple and Google Marketplaces are Killing Innovation, and How Blockchain can Solve It. The global market in recent years has witnessed a tremendous increase in the number of mobile application downloads.
According to the comScore report, the mobile app revenue reached $58 billion in 2016 from $45 billion in 2015. The same report predicts that app revenue will hit a new peak of $77 billion by the end of 2017. The figures evidently point to the emergence of a new whole industry, the one that belongs to application developers. They study the market, understand its need, determine the solution, and codify it in the form of a user-interactive mobile application. There are still some challenges, however, related to app distribution. It is true that the app revenue statistics are bullish, but one cannot ignore that they could have been higher if developers were allowed to be innovative.
What the Hell Is an Initial Coin Offering? - MIT Technology Review. Initial coin offerings are all the rage.
Dozens of companies have raised nearly $1.5 billion via the novel fundraising mechanism just this year. Celebrities from Floyd Mayweather to Paris Hilton have jumped on the hype train. But don’t feel bad if you’re still wondering: what the hell is an ICO? The acronym probably sounds familiar, and that’s on purpose—an ICO does indeed work similarly to an initial public offering. Instead of offering shares in a company, though, a firm is instead offering digital assets called “tokens.” A token sale is like a crowdfunding campaign, except it uses the technology behind Bitcoin to verify transactions. Let’s start with Bitcoin, the most popular token system. Blockchains need miners to run, and tokens are the economic incentive to mine. CoinSpace Bitcoin Wallet - Bitcoin Wallet - CoinSpace.
How to invest in bitcoin, ethereum, and other cryptocurrencies — Quartz. “I was urged to stop paying my bills to invest in more inventory.
I was urged to get rid of television. I was urged to pawn my vehicle. I just had to get on anxiety meds over all of it because I’ve started having panic attacks.” In June 2016, Sophie (name changed) quit her job in the suburbs of Fort Worth, Texas to sell for LuLaRoe, a rapidly growing clothing company that offers self-employment opportunities to American women in the form of hawking hyper-hued apparel. LuLaRoe’s consultants told her—and tens of thousands of other mostly rural and suburban women over the past five years—that she could provide for her family, join a sisterhood of supportive women, and find meaning in her life again through the conduit of colorful, stretchy fashion—all for a reasonable upfront investment of around $5,000. As economic opportunity has become more concentrated in urban areas in the US, rural communities have fallen behind.
MLMs aren’t a new business model—they’ve just done a little rebranding.
La blockchain pour les nuls. Il est des sujets qui peuvent soit passionner soit laisser complètement indifférent, la blockchain en fait sans aucun doute partie.
Cette technologie n’est pourtant pas nouvelle mais elle déchaîne les foules sur son intérêt, ses arcanes, sa complexité (ou non) et ses applications concrètes. The Ultimate Reading List for Blockchain, Token and Cryptocurrency Sources. How blockchain will revolutionise far more than money. The impact of record-keeping on the course of history cannot be overstated. For example, the act of preserving Judaism and Christianity in written form enabled both to outlive the plethora of other contemporary religions, which were preserved only orally. William the Conqueror’s Domesday Book, compiled in 1086, was still being used to settle land disputes as late as the 1960s.
Today there is a new system of digital record-keeping. Its impact could be equally large. How blockchain can help fight cyberattacks. Imagine a computing platform that would have no single point of failure and would be resilient to the cyberattacks that are making the headlines these days. This is the promise behind blockchain, the distributed ledger that underlies cryptocurrencies like Bitcoin and Ethereum and challenges the traditional server/client paradigm. In 2009, Bitcoin became the first real application of blockchain, a secure decentralized monetary exchange platform that removed the need for central brokers.
Ethereum for Newcomers. Fundamentally, currencies allow us to transfer value from one entity to another. Currencies are highly liquid and are readily and universally capable of being exchanged for goods or services. Bartering is another means of transferring value (e.g. exchanging ten sheep for one cow, or exchanging an Android for an iPhone with someone from Craigslist). Bartering is not as universal and not as liquid. You may have to wait a long period for the value transfer to complete, you may have to put in more effort to ensure the transaction goes smoothly and you may need to trust the person you’re dealing with to a high degree.

The Latest Blockchain Trials and Projects: The Race for Adoption in On. The race has been on for a while actually, but the speed has been surging with every other week. Since the end of May when we last looked at the latest blockchain pilots and the latest open-source blockchain projects, a lot has happened. A range of new players has launched blockchain trials to find the best application case and bank on blockchain application. ATB Financial, SAP and Ripple send the first real-time international blockchain payment from Canada to Germany ATB Financial, the largest Alberta-based financial institution, has collaborated with SAP, financial technology startup Ripple Labs and ReiseBank AG in Germany to send the first real international blockchain payment from Canada to Germany, as reported by SAP.

The DCS Triangle — The BigchainDB Blog. The DCS Triangle Introduction In this post, I introduce the DCS (Decentralized-Consistent-Scale) triangle as a way to compare tradeoffs among some of today’s popular decentralized systems, including Bitcoin, Ethereum, IPFS, and BigchainDB. Each system has its own complementary uses. This is an engineering statement of technology today, not of fundamental boundaries like in the CAP theorem.

Hillary Clinton and the Blockchain. Last week Hillary Clinton announced her policy goals for technology and innovation. While her continued support of computer science and STEM education, increasing open data or fighting for net neutrality wasn’t a surprise, a more unexpected announcement sits halfway through the document: “public service blockchain applications.”
As the first person to have launched a “code sprint” out of the White House and fight to use words like “hacking” on the White House blog, I can tell you that getting words like “blockchain” into an announcement was challenging. The other important thing to note is she said “application,” not “regulation.” La Blockchain pose de sérieux problèmes de confiance, de droit... et de sécurité. #Blockchain? It's complicated - Chris Skinner's blog. We had a great debate at the Financial Services Club last night between digital money sage Dave Birch of Consult Hyperion, and all things bitcoin master Jon Matonis. The debate was about whether blockchain is faster and cheaper, and it was clear from the start that this was going to be difficult as the question Dave raised is: faster and cheaper than what?
I’ll talk more about the debate in further posts but, to begin with, it is clear that there are raging arguments taking place in the corridors of banks about this technology.
