What is Cryptocurrency? The groundbreaking technology behind this ingenious new payment system is explained here: a blog about cryptocurrency and how it functions.
A cryptocurrency (or crypto currency) is a digital asset designed to work as a medium of exchange using cryptography to secure the transactions and to control the creation of additional units of the currency. Cryptocurrencies are classified as a subset of digital currencies and are also classified as a subset of alternative currencies and virtual currencies.
Bitcoin became the first decentralized cryptocurrency in 2009. Since then, numerous cryptocurrencies have been created. These are frequently called altcoins, as a blend of bitcoin alternative. Bitcoin and its derivatives use decentralized control as opposed to centralized electronic money/centralized banking systems. The decentralized control is related to the use of bitcoin’s blockchain transaction database in the role of a distributed ledger.
Decentralized cryptocurrency is produced by the entire cryptocurrency system collectively, at a rate which is defined when the system is created and which is publicly known. In centralized banking and economic systems such as the Federal Reserve System, corporate boards or governments control the supply of currency by printing units of fiat money or demanding additions to digital banking ledgers. In case of decentralized cryptocurrency, companies or governments cannot produce new units, and have not so far provided backing for
Unlike traditional currencies, which are issued by central banks, cryptocurrency is a decentralized type of money. The technology that makes bitcoin work, according to proponents, is an effectively unhackable system that could introduce trust and transparency to any online transaction.
What is Cryptocurrency?
The most important feature of a cryptocurrency is that it is not controlled by any central authority: the decentralized nature of blockchain makes cryptocurrency theoretically immune to the old ways of government control and interference. Cryptocurrencies can be sent directly between two parties via the use of private and public keys. These transfers can be done with minimal processing fees, allowing users to avoid the steep fees charged by traditional financial institutions.
While cryptocurrencies are digital currencies that are managed through advanced encryption techniques, many governments have taken a cautious approach toward them, fearing their lack of central control and the effects they could have on financial security. Regulators are concerned about the ease with which assets can be hidden.
Another issue raised by critics is that cryptocurrency systems do not always have an accessible value in real-world markets, making them more susceptible to manipulation or bubble formation.
A cryptocurrency is a digital or virtual currency designed to work as a medium of exchange. It uses cryptography to secure and verify transactions as well as to control the creation of new units of a particular cryptocurrency. Essentially, cryptocurrencies are limited entries in a database that no one can change unless specific conditions are fulfilled.
The first blockchain-based cryptocurrency was Bitcoin, which still remains the most popular and most valuable. Today, there are thousands of alternate cryptocurrencies with various functions or specifications. Some of these are clones or forks of Bitcoin, while others are new currencies that were built from scratch.
Bitcoin was created in 2009 by an anonymous person or group known as Satoshi Nakamoto. It is the largest cryptocurrency in terms of total market value. Other popular cryptocurrencies include Ethereum, Ripple and Litecoin.
Cryptocurrency works similarly to bank credit on a debit card: it is digital money that you can use to pay for some transactions online and in stores. Like a credit card, your transactions are recorded in a public log called block chain: if someone has your transaction details (your digital signature), they can use them just like cash.
The crypto in cryptocurrency refers to the cryptography that’s used to verify transactions and keep the virtual asset secure. Cryptocurrency uses decentralized technology to let users make secure payments and store money without the need to use their name or go through a bank. They run on a distributed public ledger called blockchain, which is a record of all transactions updated and held by currency holders.
The transactions are anonymous, though, so your personal information isn’t public. Cryptocurrencies are attractive to some users because of their privacy, as well as their lack of transaction fees. But they aren’t registered with a central authority, so if they are lost or stolen there generally is no way to get them back.
A cryptocurrency is a digital or virtual currency that uses cryptography for security. A cryptocurrency is difficult to counterfeit because of this security feature. A defining feature of a cryptocurrency, and arguably its most endearing allure, is its organic nature; it is not issued by any central authority, rendering it theoretically immune to government interference or manipulation.
The first cryptocurrency to capture the public imagination was Bitcoin, which was launched in 2009 by an individual or group known under the pseudonym Satoshi Nakamoto. As of September 2015, there were over 14.6 million bitcoins in circulation with a total market value of $3.4 billion. Bitcoin’s success has spawned a number of competing cryptocurrencies, such as Litecoin, Namecoin and PPCoin.
In the wake of the crisis, central banks around the world experimented with different ways to stimulate the economy. Some of these experiments included leaving interest rates at zero, buying back bonds from commercial banks and so-called “quantitative easing” – increasing the money supply in circulation by creating new money.
One of these experiments was a digital currency called e-krona, launched in 2017 as a pilot scheme by the Riksbank, Sweden’s central bank. It was an effort to bypass commercial banks when making payments and thereby make it easier for people to pay each other directly. Its goal was also to make it easier for households and businesses to access payment services outside normal banking hours.
The experiment was deemed a success and the e-krona is set to be launched in 2022.
But there is another side to cryptocurrencies like Bitcoin – they can also be used as an investment, albeit a risky one. The value of Bitcoin fluctuates wildly compared to fiat currencies like the dollar or euro.

Facebook is a social networking site that allows people to connect with family and friends.
The History of Facebook
Facebook was founded in 2004 by Harvard student Mark Zuckerberg. His roommate and college classmate Eduardo Saverin, Chris Hughes, and Dustin Moskovitz joined him as fellow Harvard students. They built a website called Facemash on October 28, 2003. Students used the site to compare two student pictures side by side and let other students decide who was “hotter” or more attractive.
On February 4, 2004, Zuckerberg launched “Thefacebook”, originally located at thefacebook.com. Six days after the site launched, three Harvard seniors, Cameron Winklevoss, Tyler Winklevoss, and Divya Narendra accused Zuckerberg of intentionally misleading them into believing he would help them build a social network called HarvardConnection.com. They claimed that he was instead using their ideas to build a competing product. The three complained to the Crimson, and the newspaper began an investigation. Zuckerberg began writing code for a new website in January 2004 and said that he was inspired by an editorial about the Facemash incident in The Harvard Crimson. On February 4, 2004 Zuckerberg launched ‘TheFacebook’, originally located at thefacebook.com. Membership was initially restricted to students of Harvard College
