How Blockchain is changing Money and Business?

A blockchain is a growing collection of cryptographically connected documents known as blocks. A cryptographic hash of the previous block, a timestamp, and transaction data are all included in each block (generally represented as a Merkle tree).

The timestamp validates that the transaction data existed when the block was published in order to get into the hash.

Because each block contains information about the one before it, they form a chain, with each new block reinforcing the preceding ones. As a result, blockchains are resistant to data manipulation since, once recorded, the data in any one block cannot be modified retrospectively without impacting all subsequent blocks.

It is frequently managed as a publicly distributed ledger via a peer-to-peer network, with nodes interacting and validating new blocks using a protocol.

Despite the possibility of forks, blockchain records are secure by design and represent a distributed computing system with exceptional Byzantine fault tolerance.

The blockchain was created in 2008 by a person (or group of people) known as Satoshi Nakamoto to serve as the public transaction record for the cryptocurrency bitcoin. The exact identity of Satoshi Nakamoto is still unknown.

Blockchain – Uses

Blockchain technology can be used in a variety of ways. The most common application of it is as a distributed ledger for cryptocurrencies like bitcoin; but, by late 2016, a few other operational products had grown from proof of concept.

As of 2016, some firms have started experimenting with blockchain technology and implementing it at a minimal level to see how it affects organizational efficiency in their back office.

1. Cryptocurrencies

The majority of cryptocurrencies rely on blockchain technology to keep track of transactions. The bitcoin and Ethereum networks, for example, are both built on its technology. On May 8, 2018, Facebook announced the formation of a new blockchain group led by David Marcus, who was previously in charge of Messenger.

Libra (formerly known as Diem), Facebook’s planned cryptocurrency platform, was formally unveiled on June 18, 2019.

Silk Road, a criminal operation that operated on Tor, accepted cryptocurrency as payment, and the US federal government has confiscated part of it through blockchain research and forfeiture.

The legality of citizens or banks possessing cryptocurrency is a grey area for governments. China uses blockchain technology in a variety of businesses, including the development of a national digital currency in 2020.

Western nations, particularly the European Union and the United States, have launched similar efforts to support their respective currencies.

2. Smart contracts

On the blockchain, smart contracts are suggested contracts that may be partially or completely enacted or enforced without requiring human participation. One of the primary aims of a smart contract is automated escrow.

Smart contracts have the merit of not requiring the services of a trusted third party (such as a trustee) to function as an intermediary between contractual parties; instead, the contract is executed directly by the blockchain network.

This could lessen friction between entities when transferring value and, as a result, allow for more transaction automation. Smart contracts based on its technology, according to an IMF staff debate from 2018, could eliminate moral hazards and improve the use of contracts in general.

“However, no viable smart contract systems have yet evolved,” says the report. Their legal status was unknown due to their lack of popular use.

3. Video games

CryptoKitties is a blockchain game that was released in November 2017. It made headlines in December 2017 when a crypto kitty character – a virtual pet – was sold for more than $100,000. CryptoKitties also demonstrated scalability issues for games on Ethereum when it caused significant congestion on the Ethereum network, accounting for roughly 30% of all Ethereum transactions.

4. Healthcare

The Wall Street Journal said that Ernst & Young was developing a blockchain to enable businesses, governments, airlines, and others to track those who have undergone antibody tests and may be immune to the COVID-19 pandemic in 2020. It was also used by hospitals and merchants to track needed medical equipment.

Furthermore, blockchain technology was employed in China to reduce the time it took for health insurance payments to be made to providers and patients.

Blockchain and internal audit

Internal audits will need to modify how information is accessed in new formats to ensure effective monitoring of organizational efficiency. Blockchain adoption will necessitate a framework to assess the risk of exposure connected with transactions using blockchain.

Internal auditors are needed to address this transformative technology, according to the Institute of Internal Auditors. To establish audit strategies that identify dangers and risks, new methodologies are required. These factors are evaluated in the Internal Audit Foundation study, Blockchain and Internal Audit.

As a result of blockchain, the American Institute of Certified Public Accountants has defined new roles for auditors.

How Blockchain Is Changing Finance

What is the source of our financial system’s inefficiency? For starters, it’s outdated, a mash-up of industrial technologies and paper-based processes cloaked in a digital coating. Second, it is centralized, making it resistant to change as well as prone to system failures and attacks.

Third, it is exclusionary, denying basic financial instruments to billions of people. Bankers have mainly avoided the kind of creative destruction that is necessary for economic vitality and advancement, even though it is messy. But there is a way out of this innovation stalemate: blockchain.

It was created to support cryptocurrencies such as Bitcoin. It is a massive, globally distributed ledger that can record anything of value and is run on millions of machines.

Because trust is established not by powerful intermediaries like banks and governments, but by network consensus, cryptography, collaboration, and clever code, money, equities, bonds, titles, deeds, contracts, and virtually all other kinds of assets can be moved and stored securely, privately, and from peer to peer.

For the first time in human history, two or more parties, whether businesses or individuals who may or may not know each other, can forge agreements, make transactions, build value without relying on intermediaries to authenticate their identities.

Moreover, establish trust, and build value (such as banks, rating agencies, and government authorities like the US Department of State), or conduct the essential business logic — contracting, clearing, settling, and record-keeping — that all types of commerce require.

ICOs, like any other radical new company idea, carry dangers. Regulatory supervision is minimal to non-existent. Due diligence and disclosures can be lacking, and several ICO issuers have gone bankrupt. The phrase “caveat emptor” applies, and many of the early backers are more gamblers than investors.

However, the genie has been let out of the bottle. When done correctly, ICOs can not only increase the efficiency of obtaining funds by lowering the cost of capital for entrepreneurs and investors, but they can also democratize global capital markets participation.

What is the role of blockchain in the corporate world? For entities transacting with one another, blockchain for business is useful. Permissioned users can access the same information at the same time using distributed ledger technology, which improves efficiency, builds trust, and reduces friction.

Blockchain technology could enable speedier payments at lower rates than banks by providing a decentralized ledger for payments (e.g. Bitcoin). Clearing and Settlement Systems: Distributed ledgers can lower operational expenses and bring us closer to real-time financial transactions.

In a variety of industries, blockchain technology has a wide range of applications. Blockchain is already being used for identity management, smart contracts, supply chain analysis, and other applications. The entire promise of blockchain technology is unlikely to be realized anytime soon.
