If you are on a personal connection, like at home, you can run an anti-virus scan on your device to make sure it is not infected with malware. If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices. Another way to prevent getting this page in the future is to use Privacy Pass. Is it possible to have an truly alternative altcoin? The developers behind new digital currency NXT think so – and they’re gaining traction. NXT works in a different way to bitcoin, and to other coins like litecoin that use different algorithms for mining. The currency isn’t mined using computing power.
How it works?
PoS works by awarding new coins to existing coinholders based on the number of coins they already have. The idea is to generate new coins without having to chew up vast amounts of energy as the bitcoin network does. NXT does this by working out how many coins everyone has, and using these figures in conjunction with a random math function to work out who will be forging the next block. That person then processes all of the transactions in the current block, and is awarded some coins for it. One of NXT’s unique characteristics is that everyone knows who is going to be mining the next block. Everyone on the network then sends their transactions to that person. This drastically reduces traffic, claims the development team, while also decreasing confirmation times practically to zero.
The team claims credit card-like transaction times. This solves a perennial issue faced by bitcoin users. They run the risk of a double spending attack, where someone sends a bitcoin and then persuades the rest of the network that it didn’t happen, enabling them to spend the coin again somewhere else. To engineer that kind of attack, the fraudster would have to mine their own block with their own, falsified transaction records, separately to the rest of the network, and then convince others miners that they should accept it as the real one. Some people suggest waiting for six confirmations, which can take longer. People on the bitcoin network often allow zero-confirmation bitcoin transactions, but they do it at their own risk.
What’s to stop someone on the NXT network from trying to convince the rest of the network that a transaction didn’t actually happen? This is where a concept called transparent forging comes in. In NXT, everyone knows who’s supposed to be mining the next block in the block chain. If they’re trying to mine a fraudulent block and fork the chain, then that means that they can’t be mining the real one. The network can detect this, and reduces that miner’s mining power to zero, thus choking off their efforts. NXT is different to peercoin, which only uses PoS for part of its base of coins, using PoW for the rest.
Peercoin will grow this percentage over time. PoS, and isn’t mining any coins, because they have already all been produced. Investors gain additional coins through PoS based on transaction fees. Unlike PoS hybrid implementations, NXT is able to reward those that protect the network while avoiding inflating the money supply. The NXT team created the entire base of NXT coins – one billion of them – in advance. 75 investors then purchased the coins, putting in a total of 21 BTC. They then began trading them directly in the forums, or via the first central exchange set up for that purpose, called DGEX.
I have foreseen this in the peercoin paper that currencies could be issued like stock IPO,” said Sunny King, founder of peercoin. Although we didn’t attempt this approach for peercoin as we think the mining industry is a better method of issuance for currencies, probably more fair, but of course this is subjective and everyone could have different opinions. John Manglaviti, King’s community development manager on peercoin, who also helped to kick off the Feathercoin community in the early days, has been involved in NXT. 12,000 worth of coins at its current market cap. Manglaviti wishes NXT all the best, and welcomes an innovative coin into the altcoin community.

PoS system, such as peercoin’s is that not all of the coins are owned by a small group at one time. If the initial distribution is rather small, in cases such as NXT, there has to be every effort from the community to encourage the original founders to distribute the coin as quickly as possible,” he warns. If hoarding occurs, it will drastically effect the liquidity of the coin, the community will lose interest and the price will plummet. BTER, which seems to be a haven for altcoins, might help to increase the coin’s liquidity somewhat. In the long run, though, the NXT developers want to expand from central exchanges to a decentralized exchange mechanism.
This is a tough technical problem, and various people have tried it in the past. NXT’s team isn’t afraid to pile on ambitious features. The team also wants to tackle some other problems, some of which have been successfully implemented with other coins, and some which haven’t. No one coin has done them all yet. One such feature is a naming and messaging system.

NXT account number, or web page. NXT’s decentralized domain name and messaging system also enables people to host their own web sites and chat to each other anonymously. This is akin to the naming system in namecoin, although it will doubtless be implemented differently under the hood. Another thing that NXT promises is coloured coins, which is something that the bitcoin community has been discussing for a long time. The crypto community grows tired of all the knock-offs and NXT provides hope for a new direction.
On the other hand, it’s a brand new coin without a proven history. It has made its code open source, and the developers continue to add to it over time. So how much is it worth? Market capitalization is a tricky thing to calculate for a coin like this. NXT and Ripple in its list, puts NXT at number 6 in market cap.
NXT is worth a tiny fraction of bitcoin – far less than, say, a litecoin or a peercoin. When it was first distributed, a bitcoin was worth 47. 6m NXT based on the amount invested, and the number of people who invested it. Or, to put it another way, each NXT was worth roughly one forty-seven millionth of a bitcoin. Now, at the current ask price, each NXT is worth roughly one six hundred thousandth of a bitcoin. That’s a decent rise in just a few months of unofficial trading. But because the team released all of them at once, the coin can obtain a large market cap very quickly.
A billion very cheap coins can be worth a lot. This makes NXT and bitcoin – even NXT and peercoin for that matter – entirely different animals. So whether you’d want to include their market cap on a broader list or create a new one with hardly any coins on it is a personal decision. One thing’s for sure: if a coin is innovative enough to warrant its own category, it’s worth keeping an eye on. But because it’s entirely digital and doesn’t necessarily correspond to any existing fiat currency, it’s not easy to understand for the newcomer. Let’s break down the basis of exactly what Bitcoin is, how it works, and its possible future in the global economy. Editor’s Note: we want to make it very clear right up front that we are not recommending that you invest in Bitcoins.
Its value fluctuates quite a bit, and it’s very likely that you may lose money. How Bitcoin Works In layman’s terms: Bitcoin is a digital currency. That’s a concept that might be more complex than you realize: it isn’t simply an assigned value of money stored in a digital account, like your bank account or credit line. Bitcoins are blocks of ultra-secure data that are treated like money. Moving this data from one person or place to another and verifying the transaction, i.
Those users are rewarded with new Bitcoins for their contributions. Those users can then spend their new Bitcoins on goods and services, and the process repeats. Except instead of moving files from one place to another, the Bitcoin network generates and verifies blocks of information that are expressed in the form of a proprietary currency. Bitcoin and its many derivatives are known as cryptocurrencies. Bitcoins by providing processing power from their computers to the distributed network, which generates new blocks of data that contain the distributed global record of all transactions. In this way, the very process of moving Bitcoins from one user to another creates the demand for more processing power donated to the peer-to-peer network, which generates new Bitcoins that can then be spent.

In layman’s terms: Imagine you’re buying a Coke at the supermarket with a debit card. The transaction has three elements: your card, corresponding to your bank account and your money, the bank itself that verifies the transaction and the transfer of money, and the store that accepts the money from the bank and finalizes the sale. A Bitcoin transaction has, broadly speaking, the same three components. Each Bitcoin user stores the data that represents his or her amount of coins in a program called a wallet, consisting of a custom password and a connection to the Bitcoin system.
The user sends a transaction request to another user, buying or selling, and both users agree. The peer-to-peer Bitcoin system verifies the transaction via the global network, transferring the value from one user to the next and inserting cryptographic checks and verification at many levels. The advanced explanation: The technical side of things is a bit more complex. Each new Bitcoin transaction is recorded and verified onto a new block of data in the blockchain. The two parties in the exchange are represented by randomized numbers that make each transaction essentially anonymous, even as they’re being verified.

In the conventional sense, Bitcoin transactions are incredibly secure. First of all, Bitcoin is real money, in the purely economic sense. It has value and can be traded for goods and services.
But as interesting as it is and as fast as it’s growing, Bitcoin simply can’t replace conventional, government-issued currency right now: your landlord probably won’t take a Bitcoin payment over a rent check. Broadly, converting Bitcoin into more standard currencies like US Dollars, British Pounds, Japanese Yen or Euro is very much like converting any of those currencies from one to the other when you’re traveling. You start with one currency, state your desired amount, give the value of the first currency plus a transaction fee, and receive the value in the converted currency in return. Coinbase is the most popular market and exchange in the United States. Note: this is not an endorsement. It offers buying and selling services for Bitcoin and other, similar cryptocurrencies, and will exchange US dollars and other standard fiat currencies for Bitcoins, as well as buying Bitcoins for USD and 31 other national fiat currencies.

There are other options for turning Bitcoin into conventional money. You can trade Bitcoins directly to another person for cash, though this is much more dangerous than going through an established system. Bitcoin mining software used local processors, and even extra processors like a computer’s graphics card, to calculate hashes for the next block in the blockchain. But this boom in generation couldn’t last. The Bitcoin system is designed to make each new block more difficult to find than the last one, reducing the amount of randomized Bitcoins that are generated and distributed. CPUs and GPUs to increase their chances of generating Bitcoin.
Now the system is so popular and so distributed that an individual user can no longer simply buy a screamin’ fast GPU and expect to make back enough Bitcoin to cover its value in conventional money. As a result, those hoping to earn conventional wealth via Bitcoin would be better off trading for it or selling goods and services rather than trying to make a mining system and run it constantly. Bitcoin’s Value Fluctuates More Than Standard Money If you’re reading this guide, it’s probably because you’ve heard that Bitcoin is valuable. But that value changes rapidly, much more rapidly than any currency from a stable economy or even most stocks and bonds. The shifts in the value of Bitcoin can be huge, too: as a function of its total value, Bitcoin fluctuates more than ten times faster than the US dollar. In 2010, each whole Bitcoin was worth less than a 25 cents in USD.

Obviously that’s a huge rate of growth and a massive opportunity for anyone who got on board early—initial Bitcoin miners might be millionaires now if they’ve held on to their Bitcoins long enough. Bitcoin’s Strengths That doesn’t mean Bitcoin won’t have its place in the future, however. Let’s talk about some advantages and disadvantages to Bitcoin over traditional currency. Bitcoin purchases between individual users are entirely private: it’s possible for two people to exchange Bitcoins or fractions of coins between wallets simply by exchanging hashes, with no names, email addresses, or any other information.
And because the peer-to-peer network uses a new hash for each transaction, it’s more or less impossible to link concurrent purchases to a single user. Conventional non-cash purchases include transaction fees: pay with a Visa credit card, and Visa will charge the merchant a few cents to verify the transaction. And of course, the cost of that charge is passed on to you in the form of higher prices for goods and services. At the moment, there are no mandatory transaction fees for Bitcoin. Individual users and merchants can submit their purchases to the peer-to-peer network and simply wait for it to be verified on the next block.
As the global supply of Bitcoins reaches its 21 million coin limit, transaction fees will become the primary method for miners to earn Bitcoins. At this point, presumably most transactions will include a small fee simply as a function of completing the purchase quickly. Because Bitcoin isn’t recognized as an official currency by any country, buying and selling Bitcoins themselves and using them to purchase goods and services isn’t regulated. So anything you buy with Bitcoins is not subject to a standard sales tax, or any other tax that’s normally applied to that item or service.
This can be huge economic boon if you’re wealthy enough and interested enough to do a lot of business exclusively in Bitcoin. Without being subject to most monetary laws, Bitcoin is effectively a barter system. Imagine your current supply of Bitcoins as a gigantic stack of potatoes: if you trade ten thousand potatoes for a new TV, the government won’t ask for a sales tax in the form of eight hundred potatoes. It simply isn’t equipped to handle any transactions not performed in its own currency.
However, you should be aware that any conventional earnings you receive from dealing in Bitcoin will be treated in the usual way. 10,000 worth of Bitcoins to your bank account via a Bitcoin market, you will need to report it as income on your taxes. Bitcoin Weaknesses So if Bitcoin is so great, why isn’t everyone using it? Well, obviously, it has some drawbacks too, especially at the current time. Any time something new comes around and challenges the status quo, the government is going to get involved to make sure that things remain the way they are supposed to be.
