The idea of a blockchain was first conceived as the mechanism supporting Bitcoin (BTC -3.33%). To solve the double-spending problem associated with digital currencies, a person known as Satoshi Nakamoto devised an immutable ledger of transactions that ties blocks of data together with digital cryptography.
While the idea works extremely well for Bitcoin and other cryptocurrencies, there are loads of other useful applications of blockchain technology. Here are 15 of them.

Applications 1 - 5
1. Money transfers
The original concept behind the invention of blockchain technology is still a great application. Money transfers using blockchain can be less expensive and faster than using existing money transfer services. This is especially true of cross-border transactions, which are often slow and expensive. Even in the modern U.S. financial system, money transfers between accounts can take days, while a blockchain transaction takes minutes.
2. Financial exchanges
Many companies have popped up over the past few years offering decentralized cryptocurrency exchanges, such as PancakeSwap (CAKE -8.19%) or Uniswap (UNI -13.28%). Using blockchain for exchanges allows for faster and less expensive transactions. A decentralized exchange also doesn't require investors to deposit their assets with the centralized authority, which means they maintain greater control and security. While blockchain-based exchanges primarily deal in cryptocurrency, the concept could be applied to more traditional investments as well.
3. Lending
Lenders can use blockchain to execute collateralized loans through smart contracts. Smart contracts built on the blockchain allow certain events to automatically trigger things like a service payment, a margin call, full repayment of the loan, and release of collateral. As a result, loan processing is faster and less expensive, and lenders can offer better rates. It also opens the door for more people to act as lenders. For example, Aave (AAVE -8.65%) allows anyone to make collateralized loans to borrowers with cryptocurrency.

11. Non-fungible tokens
Non-fungible tokens, or NFTs, are commonly thought of as ways to own the rights to digital art. Since the blockchain prevents data from existing in two places, putting an NFT on the blockchain guarantees that only a single copy of a piece of digital art exists. That can make it like investing in physical art but without the drawbacks of storage and maintenance.
NFTs can have varied applications, and ultimately, they're a way to convey ownership of anything that can be represented by data. That could be the deed to a house, the broadcast rights to a video, or an event ticket. Anything remotely unique could be an NFT.
12. Logistics and supply chain tracking
Using blockchain technology to track items as they move through a logistics or supply chain network can provide several advantages. First of all, it provides greater ease of communication between partners since data is available on a secure public ledger. Second, it provides greater security and data integrity since the data on the blockchain can't be altered. That means logistics and supply chain partners can work together more easily and have greater trust in the accuracy and timeliness of data. Tracifier, a German company, uses the technology so businesses can digitally store and share certificate verification data and track products at each step of the value chain process.
13. Secure Internet of Things networks
The Internet of Things (IoT) is making our lives easier, but it's also opening the door for nefarious actors to access our data or take control of important systems. Blockchain technology can provide greater security by storing passwords and other data on a decentralized network instead of a centralized server. Additionally, it offers protection against data tampering since a blockchain is practically immutable. Things Protocol, a distributed protocol for managing IoT devices, helps organizations develop secure IoT applications with blockchain technology.

Blockchain is in its infancy
Blockchain technology has only been around for a dozen years, and businesses are still exploring new ways to apply the technology to support their operations. With the growing amount of digital data used in our lives, there's a growing need for the data security, access, transparency, and integrity that blockchain can provide.
