What is Cryptocurrency?
Cryptocurrency is a digital currency that uses encryption techniques to regulate transactions and control access. Bitcoin was the first cryptocurrency to use blockchain technology; however, many other cryptocurrencies have since been created.
Cryptocurrencies are decentralized and do not rely on any central bank or government institution. Instead, they operate independently, using peer-to-peer networks to facilitate instant payments. There is no single point of failure, and if a network becomes compromised, it does not affect the entire system.
Cryptocurrency is becoming increasingly popular due to its anonymity. Unlike traditional banking methods where personal information is collected and stored, cryptocurrency transfers take place directly between users without the need for financial institutions.
The best thing about cryptocurrency is that it is completely unregulated. However, this means that it is not backed by anything physical and thus, it is susceptible to market volatility.
Here are some words and definitions that are associated with Cryptocurrency and Blockchain Technology.
Blockchain is the backbone to cryptocurrencies. A blockchain is a public ledger that records all transactions in chronological order while providing transparency regarding ownership. All data resides in unalterable blocks that cannot be modified. In addition to offering security, blockchains serve as tamperproof ledgers that allow for unprecedented levels of transparency and trust.
Mining is how currencies are added to the blockchain. When a transaction occurs, miners verify the accuracy of that transaction by solving complex algorithms and adding the record to a distributed ledger called a blockchain. Miners who verify the highest number of transactions are rewarded and their computers receive a small payment for their efforts.
When you perform a cryptocurrency transaction, you pay a fee to cover the costs of operating the network. Since each transaction requires verification, network participants must wait until enough fees are paid before the transaction’s veracity can be confirmed. These fees help maintain the stability of the network while ensuring that no single entity controls the creation of new coins.
A digital wallet is a software application that stores private keys and credentials associated with digital assets. Wallet providers range from free open-source applications to proprietary platforms and hardware wallets. A digital wallet secures funds and allows users to conduct transactions. Users can create unique passwords and address generation algorithms to ensure the safety of their funds.
Public Key Infrastructure (PKI)
Public key infrastructure (PKI) is the foundation of cryptography. It provides a trusted framework for establishing identities, managing permissions, and securing communications over public networks. PKI systems employ cryptographic certificates that bind together public keys and user identities. Certificates act as digital signatures that prove identity and authenticate messages sent over a network.
Identity management (IDM) refers to the processes involved in verifying user identities and granting them permission to perform specific actions. IDMs vary greatly depending on the type of organization. Most companies utilize centralized IDMs, whereas governments often use decentralized approaches. While some organizations require extensive authentication procedures, others may grant broad rights based on simple account numbers. As users interact with websites, mobile apps, and other online services, these entities track and store their interactions. By storing information about what users buy, watch, read, click, search, or share, IDMs make it possible to sell targeted advertisements, customize content, and provide personalized experiences across different devices.
Encryption involves converting plaintext into cipher text using a secret algorithm, then decrypting back into plaintext. Algorithms are mathematical transformations that can be applied to text to produce encrypted text. In cryptography, a cipher is defined as “an algorithmic transformation of intelligible material —usually writing—into unintelligible material.” Encryption is only effective when both parties hold the same value for the secret key. If one party reveals the key, encrypted messages become useless.
Where did Cryptocurrency come from and why is it important?
Cryptocurrencies have been around since 2009, but they didn't really take off until 2017. Bitcoin was created in 2008 by an unknown source, who published their work under the pseudonym of 'Satoshi Nakamoto'. In 2008, he released a paper describing how the system worked. Since then, many people have tried to create their own cryptocurrency, but only a few have succeeded.
Bitcoin is run on a blockchain. A blockchain is essentially a digital ledger where transactions occur. These ledgers are public and distributed across a network. Each transaction occurs between two parties, and once completed, the information about the transaction is stored permanently. The information is not stored centrally; rather, it's spread out across the network. Once recorded, the information cannot be changed.
The technology behind cryptocurrencies is called cryptography. Cryptography is the use of mathematical algorithms to secure data and protect privacy. Cryptocurrencies are built upon cryptographic principles to provide security, anonymity, and decentralization.
Bitcoin is the first successful cryptocurrency. It works similarly to cash, except that it uses cryptography to control its creation and transfer instead of physical currency. Bitcoins are created by miners, and mining requires powerful computers. Miners compete to solve complex math problems using these computers. The miner who solves the problem first gets to add the block of transactions to the blockchain.
There are currently almost 21,000 different types of cryptocurrencies. Some of them are based on bitcoin, but some are completely unique. There are even cryptocurrencies that combine elements of several different types of currencies.
Cryptocurrencies are decentralized, meaning no single person controls them. Decentralized systems rely on consensus among participants.
Because cryptocurrencies are decentralized, they are not controlled by banks or governments. This makes them attractive to those who want to avoid government interference. However, cryptocurrencies are still vulnerable to hacking and theft.
Cryptocurrencies have become increasingly popular in recent years. Many businesses accept them as payment, and some countries have begun issuing their own. The global cryptocurrency market cap today is $1.07 Trillion. This is a large jump in market value since its creation and I believe we will keep seeing the amount rise over the next couple of years.

Satoshi released the whitepaper in 2008, not 2013. Sorry for the mix-up. I meant to put 2008!
