Cryptocurrency and its impact on global economy.
Cryptocurrency refers to the digital currency used as a medium of exchange over the computer network and doesn’t depend on the directives of a central authority like Banks or Government to monitor its transactions. It’s a decentralised system that eliminates the need for traditional middlemen like banks when transferring money between businesses by verifying that the participants to a transaction genuinely have the money they claim to have.
Origin of Cryptocurrency:
The concept of digital currency originated way back to 1983 when an American Cryptographer, David Chaum devised a type of cryptographic electronic currency called Ecash which he implemented through Digicash in 1995.
Before it could be delivered to a destination, Digicash required user software in order to withdraw money from a bank and specify particular encryption keys. This made the digital currency impossible for a third party to track.

Satoshi Nakamoto, a pseudonym for a computer programmer or a group of programmers launched Bitcoin on January 3, 2009. Its proof-of-work system employed the cryptographic hash function SHA-256. The formation of a decentralised DNS was attempted with the creation of Namecoin in April 2011. When Litecoin was released in October 2011, SHA-256 was replaced with scrypt as the hash function. In August 2012, Peercoin was developed using a proof-of-stake and proof-of-work combination.
Proof-of-work refers to a cryptogenic proof provided by one party ( the prover) to the verifier that an amount of particular computing effort has been spent. Then, with little to no work on their part, verifiers can authenticate this expenditure.

The influence of Cryptocurrency on global economy.
Cryptocurrency has emerged as a significant force in the global economy, transforming various aspects of finance, technology, and commerce. While still relatively new, cryptocurrencies, with Bitcoin being the most prominent example, have garnered substantial attention and adoption around the world. Their influence on the global economy is multifaceted and has both positive and negative implications.

One of the key ways in which cryptocurrencies have influenced the global economy is by challenging traditional financial systems. Cryptocurrencies operate on decentralized networks, typically based on blockchain technology, which allows for peer-to-peer transactions without the need for intermediaries like banks. This decentralization has the potential to disrupt the traditional banking system and reduce reliance on centralized institutions. It empowers individuals to have greater control over their finances, eliminates barriers to entry, and provides financial services to the unbanked populations in many countries.

Moreover, cryptocurrencies have enabled the development of innovative financial products and services. They have given rise to a multitude of decentralized applications (DApps) and smart contracts, which facilitate new forms of economic activity, such as decentralized finance (DeFi). DeFi platforms offer services like lending, borrowing, and trading without the need for intermediaries, making financial transactions more efficient, transparent, and accessible. This has the potential to revolutionize traditional banking and investment practices, promoting financial inclusion on a global scale.

Cryptocurrencies have also acted as a hedge against traditional financial markets and fiat currencies. During times of economic uncertainty or political instability, investors often turn to cryptocurrencies as an alternative store of value. The limited supply and the potential for increased demand have driven significant price appreciation for some cryptocurrencies, resulting in substantial returns for early adopters and investors. This has created a new class of wealthy individuals and has sparked interest from institutional investors, who are increasingly allocating funds to cryptocurrencies as part of their investment portfolios.

However, the influence of cryptocurrencies on the global economy is not without challenges and risks. One significant concern is the volatility of cryptocurrency prices. The value of cryptocurrencies can experience rapid and significant fluctuations, which can lead to market speculation, financial losses for investors, and potential systemic risks. Regulatory uncertainty is another major challenge. Governments and regulatory bodies worldwide are grappling with how to regulate cryptocurrencies effectively. The absence of clear regulations and oversight can hinder mainstream adoption and expose users to fraud, money laundering, and other illicit activities.

Additionally, the energy consumption associated with cryptocurrency mining, particularly in the case of Bitcoin, has raised environmental concerns. The process of validating and adding transactions to the blockchain requires substantial computing power, leading to high energy consumption and carbon emissions. As the popularity of cryptocurrencies grows, addressing these environmental concerns becomes crucial to ensure a sustainable future.

Cryptocurrencies have had a significant influence on the global economy, disrupting traditional financial systems, enabling new financial products and services, and serving as a hedge against traditional markets. While cryptocurrencies offer potential benefits such as financial inclusion and innovation, challenges remain, including volatility, regulatory uncertainty, and environmental impact. As the technology continues to evolve and mature, finding the right balance between innovation, regulation, and sustainability will be key to harnessing the full potential of cryptocurrencies in the global economy.
