      "body": "The Problem\n\nIntermediaries rule the world. Whether you are a business or an individual, you must be paying hefty sum of money and sometime that too unknowingly. There is always intermediaries that stands between two parties just to make the transaction by affirming the terms and conditions. \n![smart.png](https://cdn.steemitimages.com/DQmRusMzc1owvSV9owxKiMZJUpWGLsRaM5PmwE53ZPBCsvC/smart.png)\n\nSome of them are banking institutions who verify transaction of money, law enforcement agencies which validate the legal contracts, governments and others.\nThe problem here is that they work on a centralized model where the third party intermediaries are necessary for the smooth functioning of the business or governance. \n\nFortunately, blockchain is here to solve this problem as the decentralized nature of it can help eliminate third party intermediaries. But how is this possible?\n\nThe Solution – Blockchain Smart Contracts\n![smart1.png](https://cdn.steemitimages.com/DQmQRPAntTPPZWm1MVpdDvT5VW13qReZYW8qw1kz212ojnL/smart1.png)\n\nThe third party middlemen were executing the contracts between the two parties and were able to make huge amount of commissions. This can be effectively done through the usage of smart contracts.\n\nWhat is a smart contract?\n\nIt is a piece of computer code or software which can be programmable to execute certain rules at a certain period of time or in intervals.\nThis can be visualized as (image visualization here)\nIf this happens – do this\nElse – do that\nThese specific terms if programmed can execute the rules when certain conditions are met which triggers the execution.\n\nHow smart contracts can be trusted?\n\nSmart contracts when stored in a distributed ledger cannot be faked or tampered and hence we can ensure the credibility. This also allows anybody in the blockchain node to view the transactions as it is transparent. Since it is also distributes, there’s no chance of fraud.\n\nSmart contracts can also be programmed to execute if another smart contract triggers it. This way, we can make a series or set of smart contracts to make things happen without third parties.\nAs of now, there are two major smart contract providers who can be used effectively by any business to develop smart contracts. \nThey are Bitcoin and Ethereum. Bitcoin’s RSK (Rootstock) and Ethereum’s Solidity language allows developers to develop any kind of smart contracts.\n\nReal World Examples of Smart Contracts\n![smart2.jpg](https://cdn.steemitimages.com/DQmfCm7pg6yGGK4ewYSqipukCvmKVeSFK6JNFf9NZWtxMmL/smart2.jpg)\n\nSmart Contracts in Banking\n\nBy checking the credit score and credit history and verifying the users through e-KYC, smart contracts can be able to issue loans in varying amounts. This can be done without the need of any third parties. Since, banks go through these three steps to check the eligibility before issuing loans, smart contract can effectively make this happen.\n\nSmart Contracts in Supply Chain\n\nDisputes often arise if the transported goods are delivered in broken condition or with defects. Sometimes, the packages even get lost in the supply chain. To tackle this issue, packaged equipped with smart IoT sensors track every movement of the product from the origin to the destination. If breakage happens in transit, the IoT device will be able to detect it and it broadcasts the info on the blockchain. Now, the smart contract automatically penalizes the logistics and so the user will be sent another package or simply the amount gets refunded, thus can reduce disputes.\n\nSmart Contracts in Insurance\n\nIf you’ve subscribes to the insurance provided by airlines, and if the flight got delayed, you’ll get the insurance instantly and that too automatically if smart contracts are in place. This saves effort and time needed to contact the insurance company and producing documents about flight’s status. After all, they take time verifying the claim and then issue the insurance amount. Now, which is simple?\n\nSmart Contracts in Betting\n\nLet’s say, I bet it’ll rain tomorrow and you bet it won’t. The bet amount is $10. Now, we have three options. If we are friends, then there’s trust but when it comes to betting with strangers, we need the trust be established. Instead of relying on the third party middlemen, we can program a smart contract which checks the data which the weather monitor (IoT device) broadcasts on the blockchain network. It also collects the amount from both of us, checks the weather and issues the payment to the winning bet. Simple, isn’t it?\n\nSmart Contracts in Agriculture\n\nIoT devices employed in the farms can effectively monitor the usage of chemical fertilizers and pesticides to be used in the crops. If those food products arrives the market in the name of organic foods, it can be easily identified and those involving in fraud can be penalized automatically by programming smart contracts.\nThe list doesn’t end here as the possibilities are truly endless.",

      "body": "With the tap of a button, you have the ability to communicate to your friend, a relative or your family instantly. In this modern era of messaging apps, it takes just seconds to send a message to anyone across the globe. Now imagine for a second, what happens if it doesn’t exist?\n\nSeems scary right? But the real creepy thing is when you come to know about our data privacy which is no longer present. The messenger companies make a buck out of it by selling the user data in certain cases. It’s definitely the centralization to blame for accessing massive amount of user data that are being stored in giant data centers. Let’s say you want to get married and so you searched for wedding suits online and have totally forget about it.\n\nData Privacy Concerns\n\nNow you start getting ads about the nearby coffee shops, ads about engagement rings, ads about wedding suits and so on. Wait. How is this possible? You start getting ads on your mobile phone, no matter what apps you open (unless the apps disable advertising). How do the ad companies know that you are going to marry someone in the near future? To be able to do this, the messenger app companies develop algorithms which monitor their users’ text conversations as well as audio conversations and start recognizing and labeling you. In our case, these smart algorithms label you as a soon-to-be-groom or bride and sell the data to the data brokers and also allow the advertisers in their platform to display their ads to you. The ads are relevant to you and you might be interested in it.\nBlockchain and Messaging\n\nThe real problem here is the breach of privacy. Of course, you’re not getting paid for your data. The messenger app can able to pull off bucks by monetizing your data without you even knowing it. How can we escape it? Well, the solution is already here. It is Blockchain and decentralized messenger apps, also called as dApps.\n\nDecentralized apps works by distributing the data among all the nodes of the network, and effectively retrieving them when needed. By doing this, we can make sure that there will be no point of failure as compared to the centralized messenger apps. Also, your data is in your control since the code of decentralized apps will always be open-source. You can effectively choose to monetize your data at your will. Meaning, you’ll be earning for the data you provide about yourself. Again, you can be specific while sharing your data. If you want your age to be not shared with the advertising companies, you can control this. It is up to you on what to share and what to not.\n\nThe messenger companies are already looking for ways to enable blockchain in their apps. Not to mention they are exploring ways on how also to make bucks from it. Communication is happening in lightning fast speeds and does the technology.

      "body": "To make the site more user friendly and search engine friendly, the WebPages should possess few characteristics. Those are the two wheels of a two-wheeler and if one fails, the other won’t work. The site should be made more user friendly because it makes the user engage with the content of the site. The user retention rate should be made high and we should bring down the bounce rate. Meanwhile, making the site search engine friendly will optimize the site for the search crawlers to crawl the site easily and helps in better indexing. This plays a major role while the user searches for an answer and if our site provides the answer, it should appear on the top spots of search engines.\nHere are the few things which we should focus on.\n![site2.jpg](https://cdn.steemitimages.com/DQmWn2e3D5sYEAseLVh6qPSB2uNbcD6HD7K4jcJJ2yvtecf/site2.jpg)\n1.\tResponsive Design\nThe site should be viewed in Mobile, Tablet and Desktop computers without any issues in User Interface. The content should adjust automatically by recognizing the screen size and user won’t be having difficulties accessing the page. If the site is not responsive enough, the user retention rate decreases and bounce rate increases. This results in loss of traffic, loss of top spot in search engine ranking pages among other negative consequences. It can be eliminated simply by making the site responsive.\n2.\tCross Compatibility\nPeople use various kinds of browsers for accessing internet and our site should be viewable same across the browsers. There shouldn’t be any issues with particular browsers since people tend to use IE / Mozilla Firefox / Safari / Chrome / Opera and others. \n3.\tSpeed of the Site\nSince people tend to prefer ISPs with better speed options, it is obvious that they need the information they require at lightning speeds. If we can’t able to make our site load faster, we’ll be losing a lot of valuable users. Reducing the number of HTTP requests, usage of progressive media image and CSS Sprites are highly recommended among other speed tweaks.\n4.\tUsage of Colors\nIt’s obvious that the colors play a huge role in emotional behavior of human beings. There’s a reason why restaurants use Yellow / Red color as it increases the appetite of user as well as making us hungry. Similarly, usage of colors in the theme plays a major role. The color usage should be made in such a way that it should please the eyes of users. Matching the theme with logo color is a recommended idea.\n5.\tMeta Content\nMeta content plays an important role in telling the search engines what the site is about and make it easy for the crawlers to crawl and index the webpages of our site. It is mandatory if we want to make our site search engine friendly.\nThe overall proposal is to make a site redesign in such a way that it is pleasing to users as well as the search engines.\n![site.jpg](https://cdn.steemitimages.com/DQmQ8xhx2x4rMnLrjFRxvPs8TMufiywVBkNxw1JJ5sGnHpi/site.jpg)",

      "title": "History of blockchain",
      "body": "The blockchain was first defined in the original source code for Bitcoin. While the recent interest in the blockchain often tries to separate it from that, it’s worth looking at this history – the two, together.\n![block.jpg](https://cdn.steemitimages.com/DQmUpZU4wWC43eFmhat2CaTDQ5iKMezzV8WtEUJLRowXUf7/block.jpg)\nBitcoin is a virtual currency, invented in October 2008 with the publication of “Bitcoin: A Peer-to-Peer Electronic Cash System,” a paper written by Satoshi Nakamoto (an alias. The real identity of Satoshi Nakamoto, the inventor(s?) of Bitcoin remains unknown, despite several well-publicized – and failed – attempts to “out” him). The code was released as open source in January 2009. (The next section of this guide examines the technology of Bitcoin and the blockchain in more detail.)\n\nThus, the Bitcoin network began in 2009 when Satoshi Nakamoto “mined” the first Bitcoins. Satoshi Nakamoto disappeared from the public – that is, from Bitcoin forums, papers, and code contributions – in April 2011. But even in Satoshi Nakamoto’s absence, Bitcoin continued to be developed and marketized, with the community working to address various issues with the code (including, for example, a technical glitch in 2013 that caused a fork in the blockchain).\n\nBitcoin really took off in 2013, as more websites started accepting the currency, as investors started funding more Bitcoin-related startups (more on investment in a section below), and as the price surged, hitting a record high of $1108 per Bitcoin in November of that year. But as its popularity grew, Bitcoin also faced scrutiny from law enforcement. The Department of Homeland Security shut down the Bitcoin exchange (formerly a Magic the Gathering exchange) Mt. Gox in 2013, which was at the time handling almost 70% of Bitcoin transactions. Mt. Gox declared bankruptcy the following year, amidst reports that some 744,000 bitcoins had been stolen from the site.\n\n(Some of this history might seem a bit extraneous to a discussion about the blockchain in education, but I’d argue that it’s all important to consider when we think about the security, the infallibility, and most importantly ideology of blockchain – the latter the topic of a subsequent article in this research project.)\n\nOne Bitcoin is currently worth about $415.\n\nOther cryptocurrencies have been developed based on the Bitcoin technology – Litecoin and Dogecoin, for example – although their volatility has made some investors and pundits wary. That volatility – in the code and in the community – has in recent months led many well-known Bitcoin developers to call it a failure. In a widely-circulated blog post published in January of this year, Mike Hearn wrote that “In the span of only about eight months, Bitcoin has gone from being a transparent and open community to one that is dominated by rampant censorship and attacks on bitcoiners by other bitcoiners.” In its coverage of the fallout, The New York Times cautions that “The current dispute, though, is a reminder that the Bitcoin software – like all computer code – is an evolving product of the human mind, and its deployment is vulnerable to human frailties and divergent ideals.”\n\nAs interest (and arguably and, yes, ironically, trust) in Bitcoin has waned, the reverse seems to be true about the blockchain, the technological underpinning of the cryptocurrency, which in the last year or so has received interest from banks, businesses, and governmental organizations alike.\n\nWho’s Investing in the Blockchain? \n\nFor the last few years, blockchain and Bitcoin have been hailed as “the next big thing,” and there have been plenty of predictions about a coming boom in funding for the sector. The Bitcoin news site CoinDesk has compiled a database of investments in Bitcoin- and blockchain-related startups, and from that (in mid 2015) it created a list of the ten most influential venture capital firms in the industry.\n\nAlthough many of those on CoinDesk’s list are VC firms that are interested primarily in the financial sector and in financial technologies, there are some familiar names among them, including some of the most high profile Silicon Valley investors. Those who also have substantial investments in education technology include Union Square Ventures, Khosla Ventures, Lightspeed Venture Partners, and Andreessen Horowitz.\n\nThe latter has invested $227 million in Coinbase and 21 Inc, which according to CoinDesk, “more than $1 in $4 so far invested in the industry.” It’s hardly a surprise then that Marc Andreessen has become one of the most vocal proponents of Bitcoin, calling it in a New York Times op-ed in 2014, one of the most important technologies since the advent of the Internet.\n\n(Of course, Andreessen also once called the now-defunct Kno “the most powerful tablet anyone has ever made.” So grain of salt and such.)\n\nAlthough many of the proponents of the blockchain contend that it can be separated from Bitcoin – that is, it can be utilized for something other than an alternative currency – Andreessen has argued that the two are inextricable: “a distributed ledger naturally both creates and requires a corresponding currency.”\n\nAnd while much of the most recent excitement about the blockchain’s potential relevance to education does not involve Bitcoin, there has been (at least) one example of an education-oriented cryptocurrency: EduCoin. Initially inspired by a college student at a football game holding a “Hi Mom. Send Bitcoin” sign, EduCoin sought to become a new way to finance one’s education. In 2014, EduCoin described itself this way: “We need a digital currency that can help students, educators, and third parties make secure transactions without fees, rates, or long approval times. EduCoin aims to be the worldwide standard for student transactions in the learning economy.” (Several years later, this project appears to no longer be maintained or active.)\n\nAs noted above, as the popularity of Bitcoin and related cryptocurrencies has waned (arguably at least), interest in the blockchain has remained if not grown. Blockchain-related startups now focus on things like identity management and “smart contracts.” The next section will look at some of the possible applications of the blockchain in education in more detail, but clearly these two elements – identity and contracts, particularly in the form of transcripts and assessments – have particular relevance in education. To see the breadth (or lack thereof) in the types of startups offering blockchain-related products and services, you can view a sample of 200+ of them via the funding website AngelList. Elsewhere, fintech investor Collin Thompson has posted his list of “The Top 10 Blockchain Startups to Watch in 2016” on LinkedIn.\n\nOne of the names that comes up with increasingly frequency here is Ethereum, developed by a Swiss non-profit the Ethereum Foundation. (Its founder, Vitalik Buterin, dropped out of Waterloo University and received a $100,000 Thiel Fellowship for his work on the project.) Ethereum isn’t a startup per se, although it’s clearly what tech industry folks would call a “platform move”: it’s building a blockchain – an alternate blockchain, to be clear, that isn’t connected to Bitcoin – for others to build their own startups upon in turn.\n\nEthereum describes itself as moving beyond a “world ledger” – it’s a “world computer,” a “perfect machine.”\n\nEthereum was first proposed by Buterin in 2013, and the second version of the Ethereum platform, called Homestead, was released earlier this year. (Here is a more complete history of Ethereum via the Ethereum Foundation’s blog.) The organization now boasts the fifth largest crowdfunding campaign ever, having raised over $18 million for the project in 2014 by the sale of “ether,” Ethereum’s currency.\n\nEthereum seems to be the platform upon which many big companies, such as IBM and Microsoft, are starting to experiment with the blockchain.\n\nAnd it’s probably worth noting that, to date, it’s been a big company rather than a little startup that’s made the first overtures towards blockchain-in-education. The company in question: Sony, which announced in February that it plans to develop a blockchain-based platform for assessment. Sony’s press release doesn’t give much indication of what this will look like – if it plans to use Ethereum, for example, or build its own blockchain.\n\nTo clarify the heading of this section: when we consider who is “investing” in the blockchain in education we should look at venture capital funding, technological contributions, product adoption, and, of course, marketing.",
