Google's DeepMind plans bitcoin-style health record tracking for hospitals

Google’s AI-powered health-tech diary, DeepMind Health, is planning to use a new technology loosely based on bitcoin to let hospitals, the NHS and eventually even patients track what happens to personal data in real-time. Dubbed “Verifiable Data Audit”, the plan is to create a special digital ledger that automatically records every interaction with patient data in a cryptographically verifiable manner. This means any changes to, or access of, the data would be visible.

The Promise of Blockchain Is a World Without Middlemen

The blockchain is a revolution that builds on another technical revolution so old that only the more experienced among us remember it: the invention of the database. First created at IBM in 1970, the importance of these relational databases to our everyday lives today cannot be overstated. Literally every aspect of our civilization is now dependent on this abstraction for storing and retrieving data. And now the blockchain is about to revolutionize databases, which will in turn revolutionize literally every aspect of our civilization.

IBM’s database model stood unchanged until about 10 years ago, when the blockchain came into this conservative space with a radical new proposition: What if your database worked like a network — a network that’s shared with everybody in the world, where anyone and anything can connect to it? Blockchain experts call this “decentralization.” Decentralization offers the promise of nearly friction-free cooperation between members of complex networks that can add value to each other by enabling collaboration without central authorities and middle men.

How Blockchain Works
Here are basic principles underlying the technology.

Distributed Database
Each party on a blockchain has access to the entire database and its complete history. No single party controls the data or the information. Every party can verify the records of its transaction partners directly, without an intermediary.

Peer-to-Peer Transmission
Communication occurs directly between peers instead of through a central node. Each node stores and forwards information to all other nodes.

Transparency with Pseudonymity
Every transaction and its associated value are visible to anyone with access to the system. Each node, or user, on a blockchain has a unique 30-plus-character alphanumeric address that identifies it. Users can choose to remain anonymous or provide proof of their identity to others. Transactions occur between blockchain addresses.

Irreversibility of Records
Once a transaction is entered in the database and the accounts are updated, the records cannot be altered, because they’re linked to every transaction record that came before them (hence the term “chain”). Various computational algorithms and approaches are deployed to ensure that the recording on the database is permanent, chronologically ordered, and available to all others on the network.

Computational Logic
The digital nature of the ledger means that blockchain transactions can be tied to computational logic and in essence programmed. So users can set up algorithms and rules that automatically trigger transactions between nodes.

Let’s start by examining the potential effects of this on an industry that touches all of our lives – banking. The banking industry is filled with shared resources. Consider ATM machines: each machine is owned by a single institution, but accepts cards from a huge network. This sharing requires a complicated management apparatus, mostly provided by VISA. That central entity owns the database and transaction processing layer, which makes everything else possible. If the process of using an ATM had been invented today, with the blockchain as a state-of-the-art database technology as an option, we would most likely not need an administrative entity like VISA to manage the process. Instead, the technology itself would do the heavy lifting of uniting the interests and business processes of the member banks. One can easily imagine a single global blockchain network for managing the interoperability of bank cards. Rather than creating hub-and-spoke methods for organizing our shared resources for mutual advantage, this new technology would provide solutions without any central oversight.

In a world without middle men, things get more efficient in unexpected ways. A 1% transaction fee may not seem like much, but down a 15-step supply chain, it adds up. These kinds of little frictions add just enough drag on the global economy that we’re forced to stick with short supply chains and deals done by the container load, because it’s simply too inefficient to have more links in the supply chain and to work with smaller transactions. The decentralization that blockchain provides would change that, which could have huge possible impacts for economies in the developing world. Any transformation which helps small businesses compete with giants will have major global effects.

Blockchains support the formation of more complex value networks than can otherwise be supported. Normally, transaction costs and other sources of friction associated with having more vendors keeps the number of partners in a value network small. But if locating and locking in partners becomes easier, more comprehensive value networks can become profitable, even for quite small transactions.

How technology is transforming transactions.

Consider the problem that small manufacturers have been dealing with giants like Wal-Mart. To keep transaction costs and the costs of carrying each product line down, large companies generally only buy from companies that can service a substantial percentage of their customers. But if the cost of carrying a new product was tiny, a much larger number of small manufacturers might be included in the value network. Amazon carries this approach a long way, with enormous numbers of small vendors selling through the same platform, but the idea carried to its limit is eBay and Craigslist, which bring business right down to the individual level. While it’s hard to imagine a Wal-Mart with the diversity of products offered by Amazon or even eBay, that is the kind of future we are moving into.

As we outline in “The Internet of Agreements,” our paper for the World Government Summit in Dubai, “the incidental complexity involved in business operations could go down by a very large factor, into a domain where a much more complex, contingent and interwoven business environment will emerge. Such an environment might be as different from today’s business environment as container shipping is superior to packing boats by hand.” (Disclosure: I’m the founder of Hexayurt.Capital, a fund which invests in creating the Internet of Agreements.)

For example, imagine the overhead involved in renting temporary furnishings for a house. Right now, this is not a very common practice (particularly for short stays) because of the overhead involved — insurance of each rented item, dozens of vendors, coordination costs getting everything in and out and so on. But if those transactions came down in cost by 90%, it is easy to imagine sites like AirBnB starting to offer custom furniture options in the spaces people are renting. Add robot delivery trucks to that future, and even short stay homes might have custom furnishing options. Making the kind of logistical complexity that is common to (say) theater productions or aircraft maintenance accessible for smaller events like weddings is just one area where falling transaction costs open up new kinds of business as complex value networks integrate to offer services that simple value networks cannot.

We’re going to see the potential for a trajectory of radical change in all industries. As a society, we’re experiencing a time of unprecedented technological change. It can feel like an insurmountable challenge for leaders to stay on course in such rapidly changing tides.  And yet, with each passing generation, we are acquiring more skill and expertise in navigating a high rate of change, and it is to that expertise that we must now look as the blockchain space unfolds, blossoms, and changes our world

Competitive Research 
Who's Your SEO Competition?

Now that you've brainstormed a long list of potential keywords, you may be wondering which keywords are most important. Good question! We'll spend two lessons on competitive research to help provide some answers. First, you'll learn who's your SEO competition among the top-ranked websites.

Identify the Top-Ranked Websites for Your Keywords

In this step of the SEO tutorial, you begin to evaluate your potential keywords by finding the websites currently ranking for those terms. Knowing these "keyword competitors" helps you determine whether your site belongs in the competition for that keyword.

search query changes the game and the opponents entirely, depending on what the search engine perceives the searcher's intent to be. Identifying who's competing for a particular keyword topic can tell you what type of game is being played and whether you should even step on that field.

Some keyword competitions just won't be your game.

Since your keyword choices influence who can find your website, optimize your pages for the phrases and terms that buyers, not just masses of window shoppers, might use to find what they need. You must select keywords that interested site visitors would search for (and then make sure the content on your page answers their needs AND uses those keywords). Whatever you hope your site visitors will do (whether to make a purchase, sign up for your newsletter or other), you need to figure out which keywords those people will search for.

Fortunately, the search engines are trying to figure out the same thing — what people really want — for every search query. So the best way to tell whether a keyword could lead to a conversion on your site is to see what kinds of results the search engine delivers. If at least some of the top 10 websites offer the same types of products, services or information that yours does, then that's probably a relevant keyword worth putting on the list. But don't worry. We have another free SEO tool to make your competitive research easier.

Here's how to use the Top-Ranked Websites by Keyword tool:

1. Enter a keyword or phrase below and click "Research Keyword."
2. View the list of URLs returned for each search, which may be your keyword competition (more on that in a moment).
3. Keep these lists of keyword competitors in your spreadsheet (next to each keyword), as these are sites you may want to analyze later.
    

What the Competitive Keyword Research Shows

Know Your True Competitors

Are all the top-ranking sites really my keyword competition? Well, yes and no. In the above example, one result is the Parks Service, an authority .gov website. Will your campground ever be able to compete against it? Probably not for this keyword. You may not consider the government or other high-clout sites (like Wikipedia) to be competitors. Nevertheless, where these and other search result giants are competing for the same SERP space, they're among your keyword competition.

Still, the results reveal what kind(s) of pages search engines think are most relevant to this keyword's perceived user intent. If ALL the top-ranking sites serve a different kind of visitor from the person you want to attract, then maybe you don't want to compete for that keyword.

For example, if your business designs go-kart tracks, should you optimize for the keyword "go-kart racing"? Looking at search results shows the answer: none of the top-ranked websites offer what your company offers. The search engine assumes that everyone searching for "go-kart racing" wants to go for a ride, so it will probably never consider your design company a relevant match.

You'd better keep doing keyword research looking for more relevant keyword phrases whose top-ranking websites include some true competitors. You can see how keyword research leads to competitive research, which leads to more keyword research, and so on. Now that you know who's your SEO competition for the important keywords, keep their URLs handy.

Keyword Research
How to Select Keywords

The first and most important search engine optimization step is keyword research. What is keyword research? Simply put, it's figuring out what people might search for in order to find what your website offers — what keyword topics best identify your website content. In this step of our SEO tutorial, you learn the basics of how to do keyword research, try out some free keyword research tools, and start your SEO plan of attack!

Getting Started with SEO Keyword Research

The first task is simply brainstorming. Ask yourself some basic questions to select keywords that might make good targets for search engine optimization, like:

• What is your website content about?
• What would you ask a search engine to find what your website offers?
• What do you think other searchers would ask for?
• What are your most popular pages/items about?

Most people can make a short (or long) list of keywords that might be used to find their own site. But ask other people these questions and write down their keyword suggestions, too. Doing so will help you go beyond the jargon words that only you and insiders know. When doing keyword research for SEO, you want to discover what real people in your target audience would call what your site offers.

Don't limit your ideas; brainstorm whatever subjects and phrases could lead the kinds of visitors you want to your site. Type them into a spreadsheet. Your brainstorming will "prime the keyword pump." This initial list will be expanded upon and refined in the next few steps, but start with the logical keywords.

Find Keywords People Already Use for Your Business

If your site is already live, you may have hidden keyword gold just waiting to be dug up.

• A good place to look for keywords is your internal site search. Offering visitors a search box within your site is good for users but also good for you, because it collects search query data. Looking at these queries primarily helps you improve usability (since it reveals what people want to see, what website content may be missing, and where your site navigation is weak). But you may also find nuggets of keyword gold, useful phrases that people search for. Add those to your list.

• You can find valuable data using Google Search Console (formerly called Webmaster Tools). This free service from Google gives website owners a wealth of information about their own sites (especially with Google Analytics set up, too). Particularly useful is the Search Analytics report; when you look at it by Queries, you can see what key search terms are bringing up your web pages in Google searches. Google also uses Search Console to notify you of errors or penalties, and you'll need the diagnostic SEO tools offered there to keep your site in good health. So don't miss out. (Here's how to set up Google Search Console.)
• Dig through your customer communications to find additional, actively used keywords. Talk to your customer service people to find out what customers are asking about (in their words). Also check social media sites like Facebook and Twitter to read what your community has said, and search for your primary keywords to discover how people are currently talking about your products, services or subjects.

Get Keyword Suggestions

Take advantage of free keyword research tools to find additional keywords. Our Keyword Suggestion Tool below shows you keyword ideas that are related to any seed word you enter. Type in one word or phrase at a time. The resulting suggestions come from actual search query data, so select the keywords that match your website content and add them to your growing keyword research list.

What the Keyword Data Tells You

With our tool, you can see keyword suggestions with data on the average click-through rate (CTR) and cost per click (CPC) for advertisers bidding on that keyword. It also reveals how many web pages contain those words in their Title tag (not necessarily as an exact phrase) under AllInTitle. These metrics indicate how competitive a keyword phrase may be.

You can also see an Activity column, which shows the approximate number of monthly searches for that keyword (also known as "search volume"). CAUTION: Don't get greedy looking at keyword activity counts. Record this statistic with the keyword in your spreadsheet. But keep in mind that a keyword's search volume should not overly influence your choices, especially at this point. You want to select keywords only if they reflect what your website is truly about. Going after high-volume keywords that don't relate to the rest of your content would be deceptive and even punishable as spam.

How Should You Use Search Activity Data?

Search volumes do cast light on your keyword research. They reveal what people actually call things, and they help you prioritize similar keyword phrases.

For instance, a retail site might choose to use "rolling backpacks for kids" (1,600 monthly searches) rather than "wheeled backpacks for kids" (320 monthly searches) because the first keyword phrase gets searched 5 times more often. However, that retailer should not pin its hopes on ranking for the broad term "backpacks," no matter how attractive that word's sky-high search volume looks.

The moral: Don't be tempted by the huge numbers for broad keywords. With enough time and effort, you might be able to rank for them, but you'd be battling large, established brands for unfocused visitors that might not even be ready to buy.

Bitcoin Apps You Need to Know About

 

If you are a bitcoin enthusiast, there are a few bitcoin apps you need to know about, as they might come in handy. Whether you want to earn a few free satoshis playing games in your free time, or whether you want to constantly keep track of bitcoin’s price, there is an app out there that will take care of your needs. Here are a few examples:

Cryptonator

This free app allows you to check conversion rates for over 500 different cryptocurrencies, in over 40 different exchanges. Essentially, Cryptonator makes it easy for users to find out how much cryptocurrencies people own are worth.

It also includes a portfolio tool that allows users to see how their selected coins perform over a specific period of time, as well a “winners & losers” section that show which coins are doing good, and which aren’t.

Bitcoin Ticker Widget

Bitcoin Ticker Widget is exactly what it sounds like it is: a widget that gives you bitcoin’s price directly on your home screen. Widgets with the price of other cryptocurrencies can also be set up, showing conversion rates for a few different fiat currencies. The prices shown in the widgets are taken from some of the world’s top cryptocurrency exchanges, such as BTCC and Bitstamp.

 Blockchain Game

If you want to introduce someone to bitcoin, you need to show them this game. Not only will it give you context to explain what blockchain technology is, but it will also help the other person earn a few satoshis and start playing around with bitcoin before they get serious about it. The game itself is pretty entertaining, and killing free time while earning bitcoin makes it a lot more enjoyable.

Bitcoin Map

Bitcoin Map is a free app you can install on your smartphone that shows you where you can spend your bitcoins. This way you will be able to know whether the local burger joint accepts bitcoin or not. Even if you know every brick-and-mortar store accepting bitcoins in your area, the app may still come in handy when you decide to go for a road trip. There are other Bitcoin map apps out there, but most of them only give you the location of bitcoin ATMs, not actual brick-and-mortar stores accepting the cryptocurrency.

Blockfolio

Blockfolio is a free financial app aimed at cryptocurrency enthusiasts. Not only does it show price information for bitcoin and over 800 altcoins, it can be set to send the user a notification whenever a specific currency reaches a price threshold. Moreover, as if that insane number of altcoins wasn’t enough, it also features over 30 different fiat currencies so it can reach a global audience.

zTrader

zTrader is the trading client app every cryptocurrency trader needs. It features information from most major exchanges and can show in-depth analysis on different currencies, giving the user a great market overview. The app is pretty complex and gives users tons of information that can, at first, be overwhelming. It will, however, make traders’ lives easier. The app features secure, encrypted storage of API keys, and even though it’s free to download, there is also a pro version.

Cryptocurrency Enthusiast Succesfully Mines Bitcoin on a 1985 NES Console

 

People have tried to mine bitcoin on a wide variety of devices in the past. Due to the evolution of mining hardware, most of the older devices have become obsolete for this type of purpose. That hasn’t kept users from getting creative, though, as one person has successfully created mining software for a 1985 NES. Quite an intriguing project, although it won’t make anyone rich overnight.

RetroMiner Mines Bitcoin On An NES

Although it may sound unlikely to mine bitcoin on an NES gaming system, it is certainly possible to do so. What started out as an offhanded challenge quickly turned into an intriguing project for the person who developed RetroMiner. Not everyone may see the benefit of this project, though, as it is unlikely the NES is even capable of mining bitcoin at any more than laughable speeds.

Most people do not understand the concept of bitcoin mining. Since it takes dedicated expensive hardware to perform this process efficiently these days, mining bitcoin makes little sense. Showcasing how this process works on a device most people are comfortable with, however, may sway a few people’s minds in the process. Then again, it is unlikely anyone will try to mimic mining bitcoin on a 1985 NES, though.

To put this into perspective, mining bitcoin on an 8-bit game console involves a lot more work than one would assume. Bitcoin mining is a very resource-intensive process and the 1985 NES is not a top-notch machine by any means. For its time, it was revolutionary in every way possible, but things have evolved a lot over the past 32 years. Then again, it is nifty to see someone actively mine bitcoin on such a device, albeit it may not generate any coins in the process.

The NES is not equipped to communicate with the live bitcoin network, or performing SHA-256 hashing. Communication with the bitcoin network proved to be pretty easy to implement once a custom bitcoin version was compiled. Keep in mind this involves using a Raspberry Pi as a proprietary device, though. More detailed instructions on the software involved can be found on the Retrominer website

SHA-256 hashing requires multiple 32-bit operations to take place. The NES, however, can only perform 8-bit tasks, which seemingly makes it incompatible. However, it was possible to create an open implementation of SHA256 that works just fine with 8-bit hardware. The custom ROM including the SHA256 algorithm is sent to the NES through the Raspberry Pi, though. However, in the end, the 8-bit game console is more than capable of doing its job, albeit no one should expect any miracles.

Interestingly enough, the person responsible for the Retrominer project feels there is still a lot of room for future improvements. At the same time, none of these improvements will turn 32-year-old hardware into a money making machine by any means. Eventually, the goal is to move more parts of the mining process to the NES, rather than passing through a Raspberry Pi first. All things considered, this is quite an amazing project, that goes to show old game consoles can be repurposed for other tasks with a bit of tinkering.

Bitcoin as Trend Setter:

Warren Buffett on Why Money Management is
Expensive & Inefficient

 

Increasing ambiguity in the structure of the financial industry and rapidly changing trends in investing are bringing more attention towards Bitcoin, the digital currency which traders and investors are using to avoid economic instability and financial uncertainty. Both financial and technology corporations are also actively investigating the potential of Bitcoin’s underlying technology – the Blockchain – in creating a secure, efficient, transparent and cross-sector platform for the settlement of transactions and assets.

However, still, the vast majority of investors and traders are eying potential investments in Bitcoin, possibly through fully regulated and liquid financial instruments such as the Winklevoss twins’ Bitcoin ETF. As Cointelegraph reported, the March 11 approval of the Winklevoss twins’ COIN ETF is nearing and analysts are quite optimistic towards its approval. Once approved, the ETF will open a new market for Bitcoin, encouraging hedge funds and large-scale investment firms to enter.

Warren Buffett says investors always try to beat market,
Bitcoin is a trend setter

Warren Buffett, a prominent American investor with a net worth of $76.1 bln, recently wrote to the shareholders of Berkshire Hathaway in his annual letter that wealthy investors should be able to afford superior financial services. In the letter, Buffett also mentioned that investors and traders are always trying to beat the market, as breaking the trend and investing in innovative companies often lead to the highest profit margins. Buffett himself is known be an early investor in some of the most wildly successful conglomerates, most notably the $183.7 bln beverages company The Coca-Cola Co.

To beat the market and make profitable investments, a high level of risk is involved. More to that, financial managers, investors, and hedge funds maintain a massive portfolio of investments that require immense labor. Thus, hedge funds and investment firms have been charging high fees to their clients for managing their funds. This trend, which has sustained its stability for decades, is starting to change. Hedge fund managers like Paul Tudor Jones, who was known to the financial industry for charging some of the highest fees to his clients, have been continuously decreasing fees over the past few years.

Why Bitcoin matters
and money management will continue to see declining fees

Essentially, the decline of money management fees and the sense of urgency of hedge funds managers all boil down to acknowledging new trends in the market. Over the past few years, Bitcoin has consistently been the top performing currency and assets across all markets and industries across the world. In fact, many mainstream investors, traders, and analysts in early 2017 recognized Bitcoin as the best performing asset and currency throughout 2016, offering extensive media coverage and comprehensive review of Bitcoin as an investment. As a result, Bitcoin’s market cap is continuing to reach new all-time highs.

In the near future, investors will be left with two choices: leave their money with expensive and inefficient hedge funds or invest in emerging assets or currencies like Bitcoin. The choice to invest in Bitcoin will be readily available once the Winklevoss twins’ ETF is approved.

Second Blockchain Academy Launched in Kerala, India

Kerala is to become the second Indian state to get its own Blockchain academy in a joint scheme between the Indian Institute of Information Technology and Management-Kerala, hereinafter IIITM-K and international learning and business development platform Blockchain Education Network, hereinafter BEN. The initiative was announced a recent Blockchain workshop held by the IIITM-K in Kerala’s capital Thiruvananthapuram, with director Dr. Rajasree MS confident of its potential. “Banking, health care [sic], and governance are the three major avenues where Blockchains [sic] will find applications,” he said quoted by Indian Express Sunday.

Professor S Rajeev, a consultant at Maker Village, a subsidiary incubator run by IIITM-K, added that “Blockchain [sic] technology, which leverages the idea of a distributed and decentralized ledger, will open up new avenues both in the software and hardware sectors.” The focus of such ‘academies’ in both Kerala and pioneer Bangalore remains somewhat vague but points to a desire to understand the impact of technology on various spheres of the economy. At the same time, India’s central bank last week suggested Blockchain becoming mainstream was a “pipe dream” and that such technology could only gain popular acceptance with the endorsement of authorities.
