Now to get the blockchain explained in simple words, it requires no central server to store blockchain data, which means it is not centralized. This is what makes the blockchain so powerful. Instead of the server being stored in one place, it is stored on the blockchain and is powered by many different computers/nodes. This means there is no third party to trust and pay a fee to.
At its simplest, Bitcoin is either virtual currency or reference to the technology. You can make transactions by check, wiring, or cash. You can also use Bitcoin (or BTC), where you refer the purchaser to your signature, which is a long line of security code encrypted with 16 distinct symbols. The purchaser decodes the code with his smartphone to get your cryptocurrency. Put another way; cryptocurrency is an exchange of digital information that allows you to buy or sell goods and services.The transaction gains its security and trust by running on a peer-to-peer computer network that is similar to Skype, or BitTorrent, a file-sharing system.

The best thing about Bitcoin is that it is decentralized, which means that you can settle international deals without messing around with exchange rates and extra charges. Bitcoin is free from government interference and manipulation, so there’s no Federal Reserve System‍ to hike interest rates. It is also transparent, so you know what is happening with your money. You can start accepting bitcoins instantly, without investing money and energy into details, such as setting up a merchant account or buying credit card processing hardware. Bitcoins cannot be forged, nor can your client demand a refund.
Even recent entrants like Uber and AirBnB are threatened by blockchain technology. All you need to do is encode the transactional information for a car ride or an overnight stay, and again you have a perfectly safe way that disrupts the business model of the companies which have just begun to challenge the traditional economy. We are not just cutting out the fee-processing middle man, we are also eliminating the need for the match-making platform.
See investing is one thing and living in India does offer ways to invest in Bitcoins through coinsecure but it’s price volatility and the way it is rising does ring alarm bells as it can go down by huge margins any time. What kind of an opinion you have on regulation of Bitcoins in India ? What kind of a future you see for Bitcoins in India especially after being a part of the Blockchain Summits?
In Charles Stross' 2013 science fiction novel, Neptune's Brood, the universal interstellar payment system is known as "bitcoin" and operates using cryptography.[227] Stross later blogged that the reference was intentional, saying "I wrote Neptune's Brood in 2011. Bitcoin was obscure back then, and I figured had just enough name recognition to be a useful term for an interstellar currency: it'd clue people in that it was a networked digital currency."[228]
Inter Planetary File System (IPFS) makes it easy to conceptualize how a distributed web might operate. Similar to the way a BitTorrent moves data around the internet, IPFS gets rid of the need for centralized client-server relationships (i.e., the current web). An internet made up of completely decentralized websites has the potential to speed up file transfer and streaming times. Such an improvement is not only convenient. It’s a necessary upgrade to the web’s currently overloaded content-delivery systems.
When you have your wallet, go to a section that says 'Receive Money' or 'Add funds' or something similar. There will usually be a QR-code that has your Bitcoin address encoded in it. Print out the image with the QR-code and place it next to your cash register. Your customers will typically have a Bitcoin app installed on their smartphone where they can enter the value of the purchase in USD or EUR. Their app calculates the corresponding Bitcoin value. It automatically takes the current exchange rate to get the right amount. On your wallet account you can check the confirmation of your incoming payment.
Numerous stock and commodities exchanges are prototyping blockchain applications for the services they offer, including the ASX (Australian Securities Exchange), the Deutsche Börse (Frankfurt’s stock exchange) and the JPX (Japan Exchange Group). Most high profile because the acknowledged first mover in the area, is the Nasdaq’s Linq, a platform for private market trading (typically between pre-IPO startups and investors). A partnership with the blockchain tech company Chain, Linq announced the completion of it its first share trade in 2015. More recently, Nasdaq announced the development of a trial blockchain project for proxy voting on the Estonian Stock Market.

Blockchain is the digital and decentralized ledger that records all transactions. Every time someone buys digital coins on a decentralized exchange, sells coins, transfers coins, or buys a good or service with virtual coins, a ledger records that transaction, often in an encrypted fashion, to protect it from cybercriminals. These transactions are also recorded and processed without a third-party provider, which is usually a bank.

You'd have to get a fast mining rig or, more realistically, join a mining pool--a group of miners who combine their computing power and split the mined bitcoin. Mining pools are comparable to those Powerball clubs whose members buy lottery tickets en masse and agree to share any winnings. A disproportionately large number of blocks are mined by pools rather than by individual miners.


With many practical applications for the technology already being implemented and explored, blockchain is finally making a name for itself at age twenty-seven, in no small part because of bitcoin and cryptocurrency. As a buzzword on the tongue of every investor in the nation, blockchain stands to make business and government operations more accurate, efficient, and secure.
Computing power is often bundled together or "pooled" to reduce variance in miner income. Individual mining rigs often have to wait for long periods to confirm a block of transactions and receive payment. In a pool, all participating miners get paid every time a participating server solves a block. This payment depends on the amount of work an individual miner contributed to help find that block.[86]
In the context of security, both transparency of the system and immutability of the data stored on blockchain comes into play. Immutability in computer science refers to something that cannot be changed. Once data has been written to a blockchain, it becomes virtually immutable. This doesn’t mean that the data cannot be changed – it just means that it would require extreme computational effort and collaboration to change it and then also, it would be very difficult to cloak it.
Blockchain technology helps counter issues like double spending.  The simplest way to think of blockchain is as a large distributed ledger of sorts that stores records of transactions. This “ledger” is replicated hundreds of times throughout the public network so it is available to everyone. Every time a transaction occurs, it is updated in ALL of these replicated ledgers, so everyone can see it.
in the early years of the 2oth Century, the Gold Reserve Banks of America and Europe became the property of these greedy Bankers in American and Europe, no longer owned or controlled by the US or any European country, they became the willing puppets of the Oligarch Regime. These Oligarchs did away with “paying gold to the bearer on demand” because it was now their gold! Paper currency isn’t worth anything, even the paper it is printed on, in fact, paper currency has become plastic currency in many different forms like your credit cards!
RISK WARNING: Trading of and investing in cryptocurrencies and other investment products can carry a high level of risk, and may not be suitable for all investors. Trading and investing generally is not appropriate for someone with limited resources and limited investment or trading experience and low risk tolerance. You could sustain a total loss of your investment. Therefore, you should not speculate with capital that you cannot afford to lose. You should always understand that past performance is not necessarily indicative of future performance. Before trading and investing you should carefully consider your objectives, risk tolerance, financial resources, needs, your level of experience and other circumstances. Always seek advice from an independent financial advisor before making any trade or investment.

I can see that blockchain has at least one vulnerability. Sure – decentralization and reconciliation with encryption is fine. But the one vulnerability is the interconnecting network. You foul that up and your blockchain paradigm is now vulnerable. Each node could then be compromised so that reconciliation is impossible. Blockchain does not accomodate the vulnerabilities of the infrastructure which it is using.
Evolving beyond the complex world of cryptocurrencies, blockchain applications are now showing enormous potential for many key industries. Industry analyst, Gartner, predicts that blockchain's business value-add will grow to US$176 billion by 2025.1 Although in its nascent stages and not without challenges, the technology is poised to revolutionize how consumers and businesses interact with data. Blockchain has the potential to redefine how we manage supply chains, maintain transactions and exchange assets.
The U.S. federal investigation was prompted by concerns of possible manipulation during futures settlement dates. The final settlement price of CME bitcoin futures is determined by prices on four exchanges, Bitstamp, Coinbase, itBit and Kraken. Following the first delivery date in January 2018, the CME requested extensive detailed trading information but several of the exchanges refused to provide it and later provided only limited data. The Commodity Futures Trading Commission then subpoenaed the data from the exchanges.[177][178]
Blockchain is the underlying technology behind cryptocurrencies like Bitcoin. Unlike physical currency, digital cash and cryptocurrencies come with a very real problem called Double-Spending. Let me explain what that is. When I email you a picture of my cat, I’m sending you a copy and not my original picture. However, when I need to send you money online, as much as I would love to send you a copy of it, it’s a bad idea if I really do that! With Bitcoin, there was a risk that the holder could just send copies of the same bitcoin token in different transactions, leading to “Double-Spending”.
Proof of work does not make attacks by hackers impossible, but it does make them somewhat useless. If a hacker wanted to coordinate an attack on the blockchain, they would need to solve complex computational math problems at 1 in 5.8 trillion odds just like everyone else. The cost of organizing such an attack would almost certainly outweigh the benefits.

Given the size of the sums involved, even the few days that the money is in transit can carry significant costs and risks for banks. Santander, a European bank, put the potential savings at $20 billion a year. Capgemini, a French consultancy, estimates that consumers could save up to $16 billion in banking and insurance fees each year through blockchain-based applications.
Ponzi schemes.[28] Beware of anyone making promises that you can easily make incredibly high returns by getting in on the "ground floor" of a new phenomenon, especially if that person promises you little to no risk. You should also be on the lookout for any "investment opportunity" that does not have minimum investor qualifications, or that has complicated fee structures or strategies.[29]
There are people who are good traders and who can recognize patterns from price charts. But that's something very specialized and I'm not sure if I believe in this. So for me, if you want to earn Bitcoins from this form of trading it could also be categorized as gambling. And actually it's even more risky if you compare it to a fair game where you know your odds. When you speculate with assets, you can extract your odds from historical prices. But never start believing this would tell you something about the future reliably.
A prospective miner needs a bitcoin wallet—an encrypted online bank account—to hold what is earned. The problem is, as in most bitcoin scenarios, wallets are unregulated and prone to attacks. Late last year, hackers staged a bitcoin heist in which they stole some $1.2 million worth of the currency from the site Inputs.io. When bitcoins are lost or stolen they are completely gone, just like cash. With no central bank backing your bitcoins, there is no possible way to recoup your loses.
Illiquidity. This is mostly moot due to Bitcoin’s $47 market cap but it still makes users sweat. It’s highly unlikely that Bitcoin’s price would plummet and you’d be unable to take action, but it’s still unsettling.  As more investors invest, however, illiquidity becomes a negligible risk, as there will likely always be a buyer for Bitcoins waiting.

This is going to come off rude but may I suggest you perform some basic proof-reading of your article prior to publication to fix all the grammatical errors (of which there are many) if you wish to teach your audience something new without insulting their intelligence by forcing them to fix your ill-structured sentences to clarify your own writing.
To be accepted by the rest of the network, a new block must contain a proof-of-work (PoW).[67] The system used is based on Adam Back's 1997 anti-spam scheme, Hashcash.[5][83] The PoW requires miners to find a number called a nonce, such that when the block content is hashed along with the nonce, the result is numerically smaller than the network's difficulty target.[3]:ch. 8 This proof is easy for any node in the network to verify, but extremely time-consuming to generate, as for a secure cryptographic hash, miners must try many different nonce values (usually the sequence of tested values is the ascending natural numbers: 0, 1, 2, 3, ...[3]:ch. 8) before meeting the difficulty target.
