It is quite obvious now, almost 14 years later, that blockchain has withstood the initial test of time and is here to stay for good. As such, it would be naive not to consider its future, and if course its many possible applications in the real world. In this article, we will explore just that.
Introduction
Blockchain is a distributed ledger technology that enables the creation of a decentralized, transparent, and secure system for the exchange of digital assets. While it has predominantly been associated with cryptocurrencies such as Bitcoin, blockchain has since expanded to various other industries, demonstrating its potential to fulfill various use cases. Let us discuss the many possible applications of blockchain, by starting with the most obvious one.
Need a refresher first? Check out our introduction to blockchain technology.
Cryptocurrencies
The most well-known and wide-spread application of blockchain technology is, of course, its role as the basis of cryptocurrencies.
Cryptocurrencies are digital or virtual currencies that use cryptography for security. Blockchain technology is the base upon which cryptocurrencies operate and is used to create a decentralized system for their exchange. This happens without the need for intermediaries such as banks or financial institutions, which is one of the elements that makes them so valuable.
Beyond facilitating transactions, blockchains have also enabled the creation of new forms of digital currencies, such as stablecoins. Stablecoins are a type of digital currency that is backed by a stable asset such as the US dollar or gold. With blockchain technology, stablecoins can be created and issued on a decentralized network, which makes them more secure, transparent and accessible than traditional currencies.
These two elements culminate into the rise and development of decentralized finance (DeFi) applications, which offer a range of financial services such as lending, borrowing, and trading without the need for intermediaries. DeFi applications are built on blockchains, which ensure that they are secure, transparent and tamper-proof. This has opened up new possibilities for individuals and businesses to access financial services without the need for traditional banks or financial institutions.

Finance
The financial sector is one of the most promising areas where blockchain technology is being applied, and we don’t mean just crypto. The decentralized nature of blockchain has the potential to eliminate intermediaries and reduce transaction costs, making it a perfect fit for financial applications. One of the most promising applications of blockchain technology in finance is in the area of cross-border payments. Blockchain technology can facilitate faster and cheaper cross-border transactions, eliminating the need for intermediaries and reducing transaction costs.
Some of the applications of blockchain technology in finance include:
Cross-border payments: Blockchain technology enables fast and secure cross-border payments by removing the need for intermediaries such as banks. It allows for peer-to-peer transactions, which can be completed in a matter of seconds.
Stock trading: Blockchain technology can be used to create a decentralized platform for stock trading. This platform would provide a transparent and secure system for buying and selling stocks, eliminating the need for intermediaries such as stockbrokers.
Smart contracts: Blockchain technology can be used to create smart contracts, which are self-executing contracts that are programmed to execute automatically when certain conditions are met. Smart contracts can be used for a wide range of financial transactions, such as insurance claims, trade finance, and real estate transactions.
Personal finance
We just covered finance in a more general way, but personal finance is a thing on its own. Blockchain and the cryptocurrencies it is usually associated with have the potential to truly revolutionize the way people manage their money and grow their wealth, offering anything from budgeting and saving to investing and lending.
Budgeting and Saving
Budgeting and saving are two key aspects of personal finance that can be greatly enhanced by blockchain technology. Blockchain technology can be used to create decentralized budgeting and savings applications that allow users to track their spending and save money automatically.
For example, the blockchain-based application, MyEtherWallet, allows users to set up a decentralized savings plan by creating a smart contract on the Ethereum blockchain. The smart contract automatically deducts a fixed amount of ether from the user’s wallet at regular intervals and stores it in a separate savings account.
Investing
Investing is another area where blockchain technology is making significant progress. Blockchain technology can be used to create decentralized investment platforms that allow investors to invest in a wide range of assets, including stocks, bonds, real estate, and commodities.
One of the most promising applications of blockchain technology in investing is in the area of tokenization. Tokenization involves converting real-world assets into digital tokens that can be traded on a blockchain network. This can help to make investing more accessible and transparent, particularly for people who may not have access to traditional investment opportunities.
Lending
Lending is another area where blockchain technology is being applied. Blockchain technology can be used to create decentralized lending platforms that allow borrowers to access loans without the need for intermediaries. This can help to reduce transaction costs and improve access to credit for people who may not have access to traditional lending institutions.
For example, the blockchain-based lending platform, Celsius Network, allows users to borrow and lend cryptocurrencies directly on the blockchain network. The platform uses a decentralized credit scoring system to determine the creditworthiness of borrowers, eliminating the need for traditional credit checks and reducing the risk of default.
Payment Processing
Payment processing is another area where blockchain technology is making significant progress. Blockchain technology can be used to create decentralized payment processing platforms that allow users to send and receive money directly, without the need for intermediaries.
This is equally important to businesses and private individuals alike, with people no longer relying on costly cross-border transfers through intermediaries. As such, any individual has the power to send money to friends, relatives, or businesses globally, without having to pay hefty transaction costs or having to conform to working hours and other limitations. Blockchain basically enables individuals to “be their own bank”.
Supply Chain Management
Another significant application of blockchain technology is in supply chain management. The blockchain network can be used to create a transparent and secure system for tracking goods and products from the point of origin to the point of consumption.
By using blockchain technology, businesses can create a tamper-proof and auditable record of every transaction in the supply chain. This can enhance transparency, reduce the risk of fraud, and improve accountability.
Identity Management
Blockchain technology can also be used for identity management. The decentralized nature of the blockchain network and the use of cryptography make it an ideal solution for creating a secure and transparent system for identity verification.
The blockchain network can be used to create a tamper-proof and auditable record of an individual’s identity, which can be used for various purposes, such as voting, banking, and healthcare. By using blockchain technology for identity management, individuals can have greater control over their personal data and privacy.
Digital Voting
Blockchain technology can also be used for digital voting. The use of blockchain technology can enhance the transparency and security of the voting process, reducing the risk of fraud and ensuring the integrity of the results.
By using blockchain technology, each vote is recorded on the ledger, making it tamper-proof and auditable. This enhances transparency and accountability and ensures that the results of the election are accurate and fair. We have yet to see it implemented, but the potential for holding fair and just elections on the basis of blockchain voting systems is positively huge.
Healthcare
Blockchain technology can also be used in the healthcare industry. The blockchain network can be used to create a secure and transparent system for the exchange of patient information.
By using blockchain technology, patient information can be securely and efficiently shared between healthcare providers, ensuring that patients receive the best possible care. Additionally, the use of blockchain technology can enhance the security and privacy of patient information, reducing the risk of data breaches and identity theft
Real Estate
The blockchain network can be used to create a transparent and secure system for property transactions, and this can actually be coupled with non-fungible tokens (NFTs). NFTs would have a tremendous use cases for real estate ownership, as ownership information could be stored on the blockchain in NFT format, making it impossible to fake, tamper with or somehow exploit. With the appropriate mechanisms in place, this would also quite likely make the processes buying and selling property a much more manageable and enjoyable experience.
Just imagine the real estate market digitalized into the metaverse and turned into a Sims-like game? Now that would be a sight to see.
Intellectual Property
Blockchain technology can finally solve a lot issues that have plagued creators, inventors, writers, musicians, and countless other professions. By being used for the management of intellectual property, blockchain can create an auditable record of that property.
Complete with a blockchain-enabled chain of ownership, too. This would provide a breadcrumb trail back to the very creation of whatever the thing in question is – a patent, a trademark, rights to a book, you name it. It can again also be coupled with the use of NFTs, much like in the case with real estate. It makes a lot of sense that this is where we’re heading, as lives that are more and more digital require digital solutions.
By using blockchain technology, the ownership and history of intellectual property can be securely and transparently recorded on the ledger, reducing the risk of fraud and disputes.
Conclusion
Blockchain technology has numerous applications and use cases that are transforming the way we conduct transactions and share information. From cryptocurrencies to supply chain management, identity management to digital voting, healthcare to real estate, and intellectual property management. Blockchains have the potential to enhance transparency, security, and efficiency in various industries. As more businesses and industries recognize the potential, we can expect to see more of them very soon.
