The advent of cryptocurrency is already taking precedence in our daily operations. Cryptocurrency is a digital asset that exists in the crypto world, and many call it “digital gold”. But what exactly is a cryptocurrency? You are probably curious.
It is a digital asset intended for use as a medium of exchange. Obviously, this is a close replacement for money. However, it uses strong cryptography to secure financial transactions, to verify asset transfers and to control the creation of additional units. All cryptocurrency is either a virtual currency, a digital currency, or an alternative currency. It should be noted that all cryptocurrencies use a decentralized control system, unlike the centralized systems of banks and other financial institutions. These decentralized systems operate through a distributed book technology that maintains a public finance database. A blockchain is commonly used.
What is a blockchain?
This is an ever-growing list of records that are linked and protected by cryptography. This list is called blocks. A blockchain is an open distributed ledger that can be used to record transactions between two parties so that it is verified and constant. In order for a block to be used as a distributed book, it is managed by a peer-to-peer network that collectively follows a protocol to check for new blocks. After writing the data in any book, they cannot be changed without changing all the other blocks. Thus, blockchains are provided with security and also serve as an example of a distributed computing system.
History of cryptography
David Chaum, an American cryptographer, discovered anonymous cryptographic electronic money called ecash. It happened in 1983. In 1995, David implemented this through Digicash. Digicash was an early form of cryptographic electronic payments that required custom software to withdraw banknotes from a bank. It also allowed you to specify specific encrypted keys before sending to the recipient. This property has allowed the digital currency not to be traced by the government, issuing banks or any third party.
After intensifying efforts in the following years, bitcoin was created in 2009. It was the first decentralized cryptocurrency and was created by Satoshi Nakamoto, the developer of the pseudonym. Bitcoin used SHA-256 as a cryptographic hash function (proof of operation scheme). Since the release of bitcoin, the following cryptocurrencies have been issued.
1. Namecoin (April 2011)
2. Litecoin (October 2011)
These three coins and many others are called altcoins. The term is used to refer to alternatives to bitcoin or just other cryptocurrencies.
It should also be noted that cryptocurrencies are exchanged over the Internet. This means that their use is primarily outside of banking systems and other government agencies. Cryptocurrency exchanges involve the exchange of cryptocurrency with other assets or with other digital currencies. Ordinary fiat money is an example of an asset that can be traded with cryptocurrency.
They refer to the proposed mechanism by which one cryptocurrency will be able to exchange directly with another cryptocurrency. This means that with nuclear swaps there will be no need for a third party to participate in the exchange.
