History of Blockchain

Blockchain technology has to be one of the principal innovations of the 21stcentury assumed the ripple effect it is having on various sectors, from financial to manufacturing as well as education. Unknown to many, is that Blockchain history dates back to the early 1990’s. Since its popularity started increasing a few years back, a number of requests have cropped up all but underlining the kind of impact it is destined to have as the race for digital economies heat up.

How blockchain emerged?

Stuart Haber and W. Scott Stornetta intended what many people have come to know as blockchain, in 1991. Their first work complex working on a cryptographically secured chain of blocks whereby no one could tamper with timestamps of documents. In 1992, they upgraded their system to incorporate Merkle trees that enhanced efficiency thereby enabling the collection of more documents on a single block. However, it is in 2008 that Blockchain History starts to gain relevance, thanks to the work one person or group by the name Satoshi Nakamoto.

Satoshi Nakamoto is accredited as the brains behind blockchain technology. Very little is known about Nakamoto as people believe he could be a person or a group of people that worked on Bitcoin, the first application of the digital ledger technology. Nakamoto conceptualized the first blockchain in 2008 from where the technology has evolved and found its way into many applications beyond cryptocurrencies. Satoshi Nakamoto released the first whitepaper about the technology in 2009. In the whitepaper, he provided details of how the technology was well equipped to enhance digital trust given the decentralization aspect that meant nobody would ever be in control of anything. Ever since Satoshi Nakamoto exited the scene and handed over Bitcoin development to other core developers, the digital ledger technology has evolved resulting in new applications that make up the blockchain History.

Structure of the blockchain:

In simple terms, Blockchain is a peer-to-peer distributed ledger that is secure and used to record transactions across many computers. The ledger’s contents can only be updated by adding another block linked to the previous block. It can also be envisioned as a peer-to-peer network running on top of the internet. In layman or businesses term, blockchain is a platform where people are allowed to carry out transactions of all sorts without the need for a central or trusted arbitrator. The created database is shared among network participants in a transparent manner, whereby everyone can access its contents. Management of the database is done autonomously using peer-to-peer networks and a time stamping server. Each block in a blockchain is arranged in such a way that it references the content of the previous block. The blocks that form a blockchain hold batches of transactions approved by participants in a network. Each block comes with a cryptographic hash of a previous block in the chain.

Fiat Currency Vs Cryptocurrency

Before we get into the the differences lets understand what Fiat currency and Cryptocurrency. Fiat Money is a kind of currency, issued by the government and regulated by a central authority such as a central bank. Such currencies act like legal tender and are not necessarily backed by a physical commodity. Instead, it is based on the credit of the economy.

Fiat currencies such as the US Dollar, Pound or Euro derive their value from the forces of supply and demand in the market. Such currencies are always at risk of becoming worthless due to hyperinflation as they are not linked to any physical reserves such as commodities.

Fiat currency first came into being at around 1000 AD in China before spreading to other parts of the world. Initially, currencies were based on physical commodities such as gold. It is only in the 20th century that President Richard Nixon stopped the conversion of U.S dollar into gold.

A cryptocurrency is a form of digital or virtual currency that can work as a medium of exchange. Being virtual in nature, they use cryptography technology to process, secure and verify transactions.

Unlike Fiat currencies, cryptocurrencies are not controlled by any central authority such as a central bank. Instead, they are limited entries in a database such as a blockchain that no one can change or manipulate, unless certain conditions are met.

Cryptocurrencies came into being as a side product of Satoshi Nakamoto, the brainchild behind Bitcoin cryptocurrency. Nakamoto did not intend to develop a currency but a peer-to-peer electronic cash system for facilitating transactions without any central oversight.

The decentralization aspect of the network means there is no central server where transactions are hosted or controlling authority. In a decentralized network like Bitcoin, every transaction to have ever happened is displayed for everyone to see. Each transaction file also consists of senders and recipients’ public keys.

Differences Between Fiat Money and Cryptocurrencies

While both fiat money and cryptocurrencies can be used as a means of payment, there are some differences.

Legality

Governments issue fiat currencies, which are in return regulated by the central bank. Fiat money is deemed legal tender in that it is often the official means of finalizing transactions. Governments control fiat money supply and issue policies from time to time that affects their value.

Cryptocurrencies, on the other hand, are merely digital assets that act as a medium of exchange that governments have no control over. The decentralization aspect means no central body can control or influence their value.

Some countries have banned cryptocurrencies on concerns that some of them are being used to fuel illegal activities such as terrorism and money laundering.

Tangibility

It is not possible to have a physical feel of cryptocurrencies as they operate online as virtual coins. Fiat currencies, on the other hand, have a physical aspect as they can exist as coins and notes thus possible to have a physical feel. Fiat money physical aspect at times does present a lot of challenges as it can be a nuisance to move around with vast chunks of money.

Exchange Aspect

Cryptocurrencies exist in digital form as they are created by computers and operate as private pieces of code. The means of exchange is thus purely digital. In contrast, fiat money can exist in both digital and physical form. Electronic payment services allow people to transfer fiat money digitally. In addition, people can transact with one another and exchange money physically.

Supply

A major difference between fiat money and cryptocurrency has to do with supply. Fiat money has an unlimited supply which means central authorities have no cap to the extent in which they can produce money.

Most cryptocurrencies have a cap when it comes to supply, which means there is a set amount of coins that will ever be in supply.  For example, the total number of Bitcoin coins that will ever be in supply is capped at 21 million.

With fiat money, it is impossible to tell the amount of money in circulation at any given time, but with cryptocurrencies, it is possible.

Storage

Cryptocurrencies virtual aspect means they can only exist online thereby stored in digital wallets commonly referred to as cryptocurrency wallets. While most digital wallets claim to offer secure storage, some of them have been hacked resulting in people losing a substantial amount of holdings.

The versatility of fiat money, on the other hand, means it can be stored in various forms. For instance, there are payment providers such as PayPal that allow people to store fiat money in digital form. Banks also do act as custodian of hard currencies. Cryptocurrencies and fiat money come with attributes that make them stand out as a means of legal tender regardless of jurisdiction. However, they also come with cons that have seen them continue to divide opinion around the world.

While there are many advantages of cryptocurrencies over fiat money, it seems that cryptocurrencies are not yet mature to replace the current standard payment method. It is a matter of time and not necessarily will be in the form of Bitcoin, Ethereum or any other cryptocurrency. The crypto market will most likely evolve to create a positive product that might change the current money system.
