What Is Digital Currency?

Crypto refers to cryptography. Now, what is cryptography? It’s a method of securing communication or document through encrypting and decrypting in the presence of a third party .Cryptography uses a computational algorithm like SHA-256 which is a hashing algorithm bitcoin uses. Then this system uses a public key to identify the user identity and a private key to identify the user signature. In transaction cryptography, everything through this method and then stores the data in the blockchain.

What Is Digital Currency?

A cryptocurrency is a digital form of currency that is meant to be a form of exchange. Cryptocurrency is quite similar to a modern currency other than it has no physical form. Also, Cryptocurrency does not focus on one bank or a central unit. It uses a public ledger to document users’ data. This comes with some advantages and disadvantages. In cryptocurrency, there is a limit to how many units can exist. For Bitcoin, the limit is 21 million. Due to this reason, the value of bitcoin fluctuates. Unlike other modern currency, you can not just create more of them.

Cryptocurrency runs on blockchain technology, but what exactly is a blockchain? The term has become so commonplace, its meaning and significance are often blurred. A blockchain is simply a digital ledger of transactions. This ledger (or database) is distributed across a network of computer systems. No single system controls the ledger. Instead, a decentralized network of computers keeps a  blockchain running and authenticates its transactions. 

Proponents of blockchain technology say that it can improve transparency, increase trust and bolster security of data being shared across a network. Detractors say that blockchain can be cumbersome, inefficient, expensive, and can use too much energy.         

Rational crypto investors buy a digital asset if they believe in the strength and utility of its underlying blockchain. All cryptocurrencies run on blockchain, which means crypto investors are betting (whether they know it or not) on the resiliency and attractiveness of that blockchain.

Cryptocurrency transactions are recorded in perpetuity on the underlying blockchain. Groups of transactions are added to the ‘chain’ in the form of ‘blocks,’ which validate the authenticity of the transactions and keep the network up and running. All batches of transactions are recorded on the shared ledger, which is public. Anyone can go and look at the transactions being made on the major blockchains

First Cryptocurrency Bitcoin

History of First Digital Currency (Bitcoin)

“The idea behind Bitcoin was introduced to the world on Oct. 31, 2008, at the depth of the financial crisis by a pseudonymous person called Satoshi Nakamoto,” according to Chetan Chawla, assistant professor of entrepreneurship. After that Satoshi Nakamoto posted a message on the cryptography mailing list titled, “Bitcoin P2P e-cash paper.” In it was a link to a white paper called “Bitcoin: A Peer-to-Peer Electronic Cash System.” You can find both of those online.

On 3 January 2009, a programmer named Satoshi Nakamoto created a bitcoin network. Mining the genesis block of bitcoin which was block number 0 also had a reward of 50 bitcoin. After that initially, it has no value whatsoever. Few people just trade bitcoin back and forth just for fun. On May 22, 2010, a man who lives in Florida negotiated to have two Papa John’s pizzas, valued at $25, delivered for 10,000 bitcoins. That single transaction started Bitcoin’s initial real-world price or value of bitcoin at 4 bitcoins per penny which means 400 Bitcoin for a single dollar.

Right now there are more than two thousand cryptocurrencies on the internet. Some of the popular ones are Bitcoin, Litecoin, Namecoin, Ethereum, Dogecoin, etc.

How is Digital Currency Created?

Cryptocurrency is released into the economy through the process of mining, as we defined above. But how do these digital coins become a legitimate currency in the first place?

Cryptocurrency creation depends on three main things:

  1. community of people who believe in the purpose of the coin and network … and who will eventually mine and evangelize it
  2. code to create and encrypt the software and blockchain network on which the currency will operate (which is relatively easy as most cryptocurrencies are based on the open source code of Bitcoin available on Github)
  3. The confidence of merchants to value and do business with the currency, further building trust among consumers, investors, and the general public

As of today, there are over 2,500 active cryptocurrencies, most of which serve as more than a simple payment system. Below we’ll review the most popular, listed from oldest to newest.

1. Bitcoin

Bitcoin (BTC) is the first and most famous cryptocurrency. It’s been around for almost 10 years and has been hailed as the “digital gold” of the industry.“The idea behind Bitcoin was introduced to the world on Oct. 31, 2008, at the depth of the financial crisis by a pseudonymous person called Satoshi Nakamoto,” After that Satoshi Nakamoto posted a message on the cryptography mailing list titled, “Bitcoin P2P e-cash paper.” In it was a link to a white paper called “Bitcoin: A Peer-to-Peer Electronic Cash System.” You can find both of those online.

2. Litecoin

Created in 2011, Litecoin (LTC) was introduced as the “silver” to Bitcoin’s “gold.” It was intended to be used as a lighter, more nimble currency for everyday transactions. Litecoin is a replica of Bitcoin, just on a much smaller scale — it’s faster to mine, holds a smaller value, has a greater market cap, and operates on a much more flexible algorithm.

3. Ether by Ethereum

The Ethereum network hosts both a decentralized computer system and payment system, through its main token, Ether (ETH), along with a handful of others. Ether can be traded as a cryptocurrency.Launched in 2015, Ethereum uses blockchain to replace centralized computing systems (like Google, Apple, and Amazon) that regulate, censor, and control user data on their applications. A decentralized network gives power back to the users and removes the security risk of a centralized system. Along with payment transactions, Ethereum also processes and validates programs and contracts, such as insurance payouts. Ethereum’s average block mining time is 12 seconds.
