Blockchain Technology-Introduction

Uses of Blockchain

Nowadays, there are a lot of applications for Blockchain technology exist. The main use of Blockchains is to serve as a distributed ledger for cryptocurrencies like Bitcoin; by the end of 2016, a few other operational products have also advanced past the stage of proof of concept. To assess the impact of Blockchain on organizational efficiency in their back office, several firms began testing the technology and implementing it at a minimal level as of 2016.

An estimated $2.9 billion in investments were made in Blockchain technology in 2019, an 89 percent increase from the previous year. Furthermore, the International Data Corp predicted that by 2022, corporate spending on Blockchain technology would total $12.4 billion. Furthermore, the second-largest professional services network in the world, PricewaterhouseCoopers (PwC), estimates that by 2030, Blockchain technology will have the ability to provide more than $3 trillion in annual economic value. An additional study by PwC from 2018 shows a significant demand for, and interest in Blockchain technology. PwC polled 600 business executives for this study and found that 84% had some exposure to using Blockchain technology.

The personal application of Blockchain technology has significantly increased since 2016 as well. Statistics from 2020 indicate that there were more than 40 million Blockchain wallets, compared to just over 10 million in 2016. 


The majority of cryptocurrencies record transactions use Blockchain technology. For instance, the Ethereum network and the Bitcoin network both have Blockchain as their base. On May 8, 2018, Facebook announced that it would launch a new Blockchain division under the leadership of David Marcus, formerly in charge of Messenger. On June 18, 2019, Facebook publicly unveiled Libra (now called Diem), their next cryptocurrency platform.

Through Blockchain research and forfeiture, the US federal authorities could confiscate part of the Bitcoin used by the criminal operation Silk Road, which ran on Tor. Regarding the legitimacy of their citizens' or banks' ownership of cryptocurrencies, governments have a range of positions. Blockchain technology is being used by China in several sectors, including the launch of a national digital currency in 2020. To boost their individual currencies, Western nations like the United States and the European Union have initiated analogous schemes.

Smart Contracts

Smart contracts on the Blockchain are suggested contracts that may be partially or totally enforced or implemented without involving a person. Automated escrow is one of a smart contract's primary goals. Smart contracts enable the Blockchain network to carry out contracts independently, doing away with the need for a trustee or other dependable third party to act as a go-between for the contractual parties. As a result, a higher degree of transaction automation may be possible by reducing the friction that exists between entities while transferring value. According to a 2018 IMF staff debate, Blockchain-based smart contracts may lessen moral hazards and improve the usage of contracts in general. "No practical smart contract solutions, however, have yet to appear."Their legal status was hazy because they weren't used frequently.

Financial Services

Many banks have indicated an interest in integrating distributed ledgers for use in banking. They are collaborating with businesses to build private Blockchains, and according to an IBM research from September 2016, this is happening more quickly than anticipated.

This technology is appealing to banks because it can expedite back-office settlement processes.They can be carried out privately or on a public, regulated stock market.Additionally, as the Blockchain business has developed, institutions have seen that technology serves as the foundation for a completely new financial sector, with all the consequences it implies.

To investigate how Blockchain technology may be utilized in financial services to improve efficiency and save costs, banks like UBS are building new research laboratories devoted to the technology.

German bank Berenberg considers Blockchain to be an "overhyped technology" that has had several "proofs of concept," but still faces significant obstacles and has relatively few success stories.

Initial coin offers (ICOs) and security token offerings (STOs), a new kind of digital asset also referred to as digital security offerings, have also been made possible by the Blockchain (DSOs). STO/DSOs are used to tokenize both conventional assets like business shares and more novel ones like intellectual property, real estate, art, or specific goods. They may be conducted in private or on a controlled public stock exchange. Services for compliance tokenization, private STOs, and public STOs are offered by a variety of organizations operating in this market.


Blockchain technology has been used to monetize video games using non-fungible tokens and cryptocurrencies (NFTs). In many online games, players can use skins or other in-game items to customize their characters. For in-game currency, these things may be acquired and traded with other players. Even while some nations view video games as gambling, several of them also let players exchange virtual goods for real money. Because this has given rise to grey market problems like skin gambling, publishers have typically been reluctant to allow players to make real-world money from their games. Players may generally trade these in-game objects in Blockchain games for cryptocurrency, which can subsequently be converted into real money.

CryptoKitties, which debuted in November 2017, was the first game to use Blockchain technology.In this game, players used Ethereum money to buy NFTs, which were virtual pets they could breed to produce new NFTs with a combination of their characteristics. When one virtual pet in the game sold for more than $100,000 in December 2017, it garnered media attention. When CryptoKitties caused substantial network congestion in the beginning of 2018 and accounted for almost 30% of all Ethereum transactions it also served as an example of the scalability issues for games on Ethereum.

Since these games tend to focus on using Blockchain for speculation rather than more traditional sorts of gaming, which provide little allure to most gamers, by the early 2020s, there had not been a breakthrough success in video games utilising Blockchain. Due to the difficulty in forecasting their income, such games also carry a significant risk for investors.GameFi, a word that denotes the confluence of video games and financing often supported by Blockchain money, saw a comeback in popularity in the second half of 2021. Businesses have plans for metaverse content, and certain games have had limited success, such as Axie Infinity during the COVID-19 epidemic. Major game publishers including Take-Two Interactive, Electronic Arts, and Ubisoft have all stated that their companies are seriously contemplating creating Blockchain- and NFT-based games in the future.

In October 2021, Valve Corporation forbade the hosting of Blockchain games, including those utilizing cryptocurrencies and NFTs, on their widely used Steam digital retail service. This was a further violation of Valve's ban against games that provided in-game goods with monetary value. It was claimed that Valve's prior participation in gambling, notably skin gambling, had an impact on the decision to restrict Blockchain games. Because most PC gamers associate Blockchain and NFT games with scams and fraud, both journalists and players welcomed Valve's move. Following Valve's rejection, Epic Games, which operates the Epic Games Store in opposition to Steam, declared that they will allow Blockchain games.
