Cryptocurrency continues to move into the spotlight. Nearly everyone has heard of cryptocurrency at this point, and many have developed an understanding of some of the aspects of how it works. Most have heard of Bitcoin, and even more have heard of other alternative cryptocurrencies that exist today, such as Litecoin, Ethereum, and Ripple. While many people have become familiar with cryptocurrency, it often seems as though these virtual currencies came out of thin air and suddenly burst on the scene. The truth is that these digital coins had a colorful history prior to becoming more widely known.
The Potential to Transform the Financial World
Yes, the development of cryptocurrency is relatively new, with the first successful cryptocurrency, Bitcoin, being created in 2009. However, the concept of a digital currency had been proposed by various developers and innovators since the 1980s.
Early attempts at digital currencies such as DigiCash, Beenz, and Flooz were developed in the 1990s. However, these systems relied on a Trusted Third Party, which acted as a central authority to verify and facilitate transactions. This meant that users had to trust the third party to handle their transactions, which went against the decentralized nature of cryptocurrency.
Bitcoin, on the other hand, was the first successful cryptocurrency to use a decentralized system, called blockchain. The blockchain is a distributed ledger that records all transactions in a secure and transparent manner, without the need for a central authority to verify them. This allows for peer-to-peer transactions without the need for intermediaries.
Since the creation of Bitcoin, numerous other cryptocurrencies have been developed, each with its own unique features and capabilities. While there are still some challenges and limitations associated with cryptocurrencies, they have the potential to revolutionize the financial world by providing a more efficient and secure way to transfer value.
The Emergence of Bitcoin
Many years later, in 2008, a white paper was published under the alias of Satoshi Nakamoto. While the true identity of Satoshi Nakamoto is not known—and it is possible that it could be a single programmer—most believe that a group of programmers operates under this alias. A white paper is a type of technical document that is created to explain a scientific project of some kind. In this case, the white paper was titled “Bitcoin: A Peer-to-Peer Electronic Cash System.” Around the same time that this paper was published, the domain name bitcoin.org was purchased, and the software used to mine Bitcoin was also released for the first time. By the following year, 2009, Satoshi Nakamoto sent some Bitcoin to another person, effectively launching the first digital currency.
What Makes Bitcoin So Unique?
The primary difference between the way that Bitcoin worked and the attempts at earlier versions of cryptocurrency was demonstrated in its use of a decentralized network to verify transactions, bypassing banks and other third parties. The decentralized network made for a more secure process and a true person-to-person payment method. The updated level of security solves a problem that has been present ever since the first digital currencies were developed. In order to prevent the possibility of duplicating transactions, a new type of transaction ledger emerged: a distributed network.
While the modern-day distributed networks were created in the 1960s and 1970s, using them for verification purposes in a transaction ledger is what makes the blockchain technology that forms the core of Bitcoin so unique. Unlike traditional methods of processing credit card payments—in which one computer on a distributed network is responsible for the verification of financial transactions—with Bitcoin, the blockchain technology distributes the responsibility for verification across the entire network.
For security purposes, this makes it nearly impossible to duplicate or change transactions, as the information is contained and verified across the entire network in multiple locations. Every block on the hypothetical chain contains information about financial transactions, along with a unique identifier, as well as the information contained on every other block on the chain before that one. It is this method of distributing information and verification among the distributed network that helps to make Bitcoin secure.
