What Is Cryptocurrency and How Does It Work? – A blog about the history of cryptocurrency along with where it is today.
The history of money has always been one thing in common: it’s been controlled by a central authority. You see, someone had to be responsible for ensuring the value of money and how much there was in circulation. For example, you can’t just print as much money as you want because then all that money would have no value.
There have been many different kinds of money throughout history, but most people agree that the first true form of currency came from Ancient China around 1,000 BC. The Chinese used coins made from bronze, copper and iron to pay for goods and services. Then the Egyptians used grain to make bread for currency later on down the road.
Eventually paper money came around in China in 900 AD and then the Ancient Romans began using paper bills as receipts for gold and silver coins around 300 BC. These early forms of paper currency were eventually issued by the government and had a fixed value based on how much gold or silver they were worth. We now call this type of currency fiat money. This is an important term because it’s what many cryptocurrencies are trying to replace: fiat money.
In its essence, cryptocurrency is
What Is Cryptocurrency and How Does It Work?
In the past few years, cryptocurrency has been all the rage. From 2017 to this day, most people are familiar with Bitcoin, Ethereum, and Litecoin. But what exactly is it? What are the advantages and disadvantages of using it? And how does it work? Let’s go back to basics and see what makes cryptocurrency tick.
What Is Cryptocurrency, Really?
Cryptocurrency is a digital asset that can be used as a medium of exchange or a store of value. It is secured by cryptography so that it cannot be counterfeited or double spent. Cryptography also makes it decentralized, meaning that there is no single point of failure (e.g., a central bank) in its economy. Due to this decentralization, cryptocurrency transactions are processed on a peer-to-peer network. The “coins” themselves are not physical objects and cannot be exchanged directly for physical goods or services; they are only used to purchase these things from the parties who accept them as payment options. As such, you need to keep your cryptocurrency in a digital wallet (unless you have paper currency with physical wallets for them).

Currently there are
Cryptocurrency is a type of digital currency that uses cryptography for security and anti-counterfeiting measures. Public and private keys are often used to transfer cryptocurrency between individuals.
Despite the name, there is no physical coin to speak of, Bitcoin is a completely electronic form of money. Unlike conventional fiat currencies however, there is no central bank that can issue more when they feel it’s needed. Instead, Bitcoins are created or “mined” by distributed computer networks. In order to create a Bitcoin, computers known as “Bitcoin Miners” use specialized software and hardware to solve extremely complex mathematical problems. In return for their labor, miners get rewarded with newly created Bitcoins. These types of problems become exponentially harder as each new block of Bitcoins is mined.
Each Bitcoin miner is competing with all the other miners on the network to be the first one to correctly assemble the outstanding transactions into a block by solving those specialized math problems. In exchange for validating the transactions and solving these problems, Bitcoin miners are rewarded for all of the transactions they process. They receive fees attached to all of the transactions that they successfully validate and include in a block. In addition, the new blocks created must contain proof of work, or PoW, which takes the

Cryptocurrency is most well-known for its decentralized transaction management and use of blockchain technology. A blockchain functions as a decentralized digital ledger that records transactions across many computers so that any involved record cannot be altered retroactively, without the alteration of all subsequent blocks.
Bitcoin became the first decentralized cryptocurrency in 2009. Since then, numerous cryptocurrencies have become available. 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.
Cryptocurrency is a form of payment that can be exchanged online for goods and services. Many companies have issued their own currencies, often called tokens, and these can be traded specifically for the good or service that the company provides. Think of them as you would arcade tokens or casino chips. You’ll need to exchange real currency for the cryptocurrency to access the good or service.
Cryptocurrencies work using a technology called blockchain. Blockchain is a decentralized technology spread across many computers that manages and records transactions. Part of the appeal of this technology is its security.
A defining feature of cryptocurrencies is that they are generally not issued by any central authority, rendering them 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.
Cryptocurrency is a digital representation of value that functions as a medium of exchange, a unit of account, and/or a store of value. Cryptocurrencies run on decentralized networks, which means that they operate on a user-to-user (or peer-to-peer) basis. In other words, there is no central authority in control of transactions or the production of currency; instead, cryptocurrencies can be produced by anyone who has the necessary computing power to do so.
The History of Cryptocurrency
Cryptography is the study and use of techniques for secure communication in the presence of third parties. It involves creating written or generated messages that can only be read by the sender and the intended recipient(s). Cryptography dates back to ancient civilizations with writing systems, like Egypt’s hieroglyphs and Mesopotamia’s cuneiform script.
In the middle ages, cryptography played an important role in diplomatic communications. In medieval times, letters were often encrypted using ciphers and sent to distant places via carrier pigeons. These codes were essential to keeping secrets and also preventing enemy interception during wartime.
In modern times, encrypted messages are transmitted through multiple channels: email, faxes, instant messaging apps like WhatsApp, etc. The NSA has been
Bitcoin, the first cryptocurrency ever created has indeed become the most widely used digital currency on earth. Ever since the existence of Bitcoin in 2009, it has witnessed unprecedented growth across the world. The reason for its worldwide acceptance is no other than its ability to changed the way transactions are conducted in many electronic platforms. Conventionally, electronic card transactions take approximately three business days to get confirmation. On the other hand, Bitcoin transactions take few minutes to be confirmed on the blockchain.
Bitcoin was created in 2009 by Satoshi Nakamoto, a pseudonymous person or group who wanted to create a new form of money that wasn’t controlled by a central authority like a government or bank. Many people do not know that Bitcoin is not a new form of money but just a new way of recording money that already exists. At its core, Bitcoin is just an accounting system that records how much money flows from one person to another. The big innovation with Bitcoin is that anyone can use this accounting system and participate as an accountant (called miners).
