It makes sense that blockchain technology was first introduced as a way to breathe some fresh air into the financial sector. Originally created at the height of the 2008 global financial crisis as the operational backbone of Bitcoin, blockchain’s distributed ledger technology is a safe and secure method to transfer and catalog data.

In short, blockchain is a public ledger capable of recording the origin, movement and transfer of anything of value. Instead of relying on a central authority, like banks, blockchain requires unanimous approval from the individual nodes in the blockchain to process a payment or transfer a good. The ledger technology is most attractive to the financial sector because it solves many problems plaguing the industry today, namely security and efficiency.

Blockchain in Finance Examples

  • Smart contracts
  • Simplified payment processing
  • Advanced trading and investing
  • Loyalty and rewards programs
  • Upgraded digital identity management

Blockchain subverts institutions in a way that makes today’s current financial industry appear archaic, so it’s no surprise the powers that be in the world of finance are looking for their seat at the table. DLT technology has the potential to expand the global economy to $1.76 trillion by 2030, and this possibility has risen with the popularity of blockchain wallets and cryptocurrencies. 

The word “disruptive” is used all too frequently nowadays, especially in the technology space, but blockchain truly has the ability to shake the multi-trillion dollar financial industry to its core. 

Here are just a few examples of blockchain in the finance sector doing just that.

Smart Contracts on Blockchain

Arguably the most impactful application of blockchain in finance is its ability to efficiently establish trust through smart contracts.

Smart contracts are similar to physical contracts, except the stipulations of the contract are fulfilled in real time via the blockchain. Smart contracts are beneficial, especially to the finance sector, for numerous reasons. These contracts are fulfilled instantly after all stipulations are met, do not require any middlemen and add heightened levels of security.

Jeff Garzik, co-founder of blockchain company Bloq, says smart contracts are beneficial to parties looking for very specific outcomes, such as when a contract is fulfilled by both parties following all the predetermined rules and dissolves under violations. A good example of this is investing.

When an individual invests in a company, the rules and stipulations are clearly established between the two parties. The unambiguous nature of the contract is helpful because the blockchain can then enforce those rules using its network of computers to check that all contractual agreements have been met (i.e., the investor has enough money, they invested in the proper amount of shares, etc.) before the investment moves forward.

Smart contract technology is currently at the top of almost everyone’s needs because of its efficiency and privacy. Here are companies instituting blockchain-based smart contracts in an effort to get ahead of the curve.

Blockchain Payment Processing

One of the most attractive applications of blockchain in fintech is its ability to process payments almost instantaneously and in a manner that protects data integrity.

Because the basis of DLT is to bypass centralized institutions, moving money from peer-to-peer is as simple as pressing a “send” button on a phone. Once initiated, the nodes in the blockchain work to unanimously accept or deny the payment in an instant. There’s no need for cash to sit in limbo for days while the bank processes the transaction, nor is it burdened by exorbitant fees.

By conducting money transfers with blockchain, both customers and banks could save an unprecedented amount of time and money. Blockchain-based currencies are also universal, meaning there are no exchange rates, international transfer fees or confusing country-by-country laws that prohibit the transfer of cryptos.

Here are a few examples of companies using blockchain to shake up the payments industry.

Blockchain Trading

Blockchain technology has the capability to transform the stock market by cutting down complicated and time-consuming processes, high costs and security risks.

A traditional stock market has numerous players, including investors, brokers, regulatory agencies and the centralized institution processing the investments. An investment can take up to three days to process because of communication between intermediaries, causing lag and uncertainty in the process. Blockchain, featuring smart contracts and a decentralized process, promises to bring speed, accuracy and efficiency to the investment process.

Since blockchain runs on smart contracts, an investment can be fulfilled immediately, rather than waiting a few days, after the blockchain deems that investment valid. The peer-to-peer investment process — in this case an individual investing directly with a company instead of through a broker — speeds up the process and eliminates unnecessary steps. Blockchain’s tightened security encryption protocols severely minimize the risk of a financial data breach.  

Blockchain has also introduced another breakthrough investment idea in the form of Initial Coin Offerings. Instead of the traditional method of raising capital in an Initial Public Offering on the stock market, ICOs offer digital tokens that represent ownership stakes in a company.

More companies are turning to blockchain-based ICOs because they offer a faster, safer and more accurate way of collecting capital. ICOs have already helped raise $3.2 billion through July of 2022

These organizations are evolving the investment process into a lean, mean blockchain machine.

Blockchain Loyalty and Rewards Programs

Maintaining and growing a customer base can make or break many companies. It’s no coincidence that well-performing stocks — like Apple, Disney and Amazon — have expansive customer loyalty programs and millions of diehard fans. Businesses looking to increase revenue and retain customers have found another solution: blockchain-based loyalty rewards.

For most companies, current loyalty programs are hard to keep data on, are outdated and are at severe risk of data breaches. In a 2018 study, IBM found that 73 percent of respondents believe businesses value profits over data security and that 75 percent won’t even buy a company’s products if they don’t trust the company to protect their personal information. Customer loyalty programs have become a target of cyber attackers, but blockchain is a potential solution for making the programs safer, larger and more precise.

The finance industry, like any business, wants a piece of the massive data and profits customer loyalty rewards programs can bring. Blockchain can optimize the process further by reducing costs, enabling a seamless, real-time program and safeguarding important data. The implementation of smart contracts allows customers to collect rewards in real-time and for businesses to manage their data better.

Centralizing a customer’s loyalty programs in one blockchain-based wallet encourages consumers to use their rewards more frequently. Additionally, customers will build a trust and affinity for companies using a high-level security blockchain to secure their personal information.

Here are examples of companies helping to implement blockchain-based rewards programs.

Digital Identity on Blockchain

One of the most serious responsibilities of financial institutions is maintaining the integrity of a customer’s digital identity, comprising some of our most sensitive information. We trust banks with safeguarding our passport information, biometric scans, social security number, accounts and addresses with the expectations that these institutions will keep them private.

Unfortunately, over 2.8 million consumers in 2021 reported fraud cases, including cases of stolen credit and bank information, that amounted to more than $5.8 billion in losses. Blockchain has the ability to stop hackers in their tracks.

The most significant endorsement of blockchain’s security prowess came at the 2018 World Economic Forum in Davos, Switzerland. The Forum concluded blockchain increases trust, accountability and efficiency in data security. Notably, the conference indicated that the financial industry can usher in a new age of digital identity security by leveraging blockchain’s decentralized mechanisms against increased risk and cyber attacks.

Here are a few companies helping the financial sector maintain the integrity of millions of digital identities.
