The idea of a blockchain was first developed as a mechanism for Bitcoin (WKN:BTCEUR). To solve the problem of spending money twice in digital currencies. So Satoshi Nakamoto developed an immutable transaction book that linked blocks of data together using digital cryptography.
While the idea works very well for bitcoin and other cryptocurrencies, there are many other useful applications of blockchain technology. Here are 15 of them.

1. Money transfers
The original concept behind the invention of blockchain technology is still a great application. Money transfers using blockchain can be cheaper and faster than using existing money transfer services. This is especially true for 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 just minutes.
2. Financial Exchanges
In recent years, many companies have emerged that offer decentralized cryptocurrency exchanges. Using blockchain for exchanges enables faster and cheaper transactions. Also, with a decentralized exchange, investors don't have to deposit their assets with a central authority, which means they have greater control and security. Although blockchain-based exchanges deal primarily in cryptocurrencies, the concept could be applied to traditional investments as well.
3. Lending
Lenders can use the blockchain to make secured loans using smart contracts. Smart contracts built on the blockchain allow certain events to be triggered automatically, e.g. B. A service payment, a margin call, the full repayment of the loan, and the release of collateral. This makes loan processing faster and less expensive, and allows lenders to offer better terms.
4. Insurance
Using smart contracts on a blockchain can provide more transparency for customers and insurance providers. Recording all claims on a blockchain would prevent customers from filing duplicate claims for the same claim. In addition, the use of smart contracts can speed up the payment process for applicants to make.
5. Real Estate
Real estate transactions require a lot of paperwork to verify financial information and ownership, then transfer deeds and titles to the new owner. Using blockchain technology to record real estate transactions can provide a more secure and accessible method of verifying and transferring property rights. This can speed up transactions, reduce paperwork and save money.
6. Secure personal information
Storing data such as your Social Security number, date of birth, and other identifying information in a public registry (z. B. of a blockchain) can be more secure than current systems, which are more vulnerable to hacking. Blockchain technology can be used to secure access to identifying information while improving access for those who need it in industries such as travel, healthcare, finance and education.
7. Voting
When personal identity data is stored on a blockchain, we are just one step away from being able to use blockchain technology to vote as well. Blockchain technology can be used to ensure that no one votes twice, that only eligible voters can vote, and that votes cannot be manipulated. It can also make voting more accessible by making it as easy as pressing a few buttons on your smartphone. At the same time, the cost of holding an election would drop significantly.
8. Benefits to the government
Another way digital identities stored on a blockchain can be used is to manage government benefits such as Social Security, Medicare and Medicaid. Using blockchain technology could reduce fraud and the cost of administration. At the same time, digital disbursement on the blockchain allows beneficiaries to receive funds more quickly.
9. Securely sharing medical information
Storing medical records on a blockchain allows doctors and medical professionals to have accurate and up-to-date information about their patients. This can ensure that patients who see multiple doctors receive the best care possible. It can also speed up the system for retrieving medical records, allowing for faster treatment in some cases. And if insurance data is stored in the database, physicians can easily verify that a patient is covered and that the cost of treatment is covered.
10. Royalties for artists
Using blockchain technology to track music and movie files distributed over the Internet can ensure that artists are paid for their work. Because blockchain technology was invented to ensure that the same file only exists in one place, it can help curb piracy. In addition, using a blockchain to track plays on streaming services and a smart contract for payments can provide more transparency and ensure that artists receive the money they are due.
11. Non-fungible tokens
Non-fungible tokens, or NFTs, are commonly seen as a way to own the rights to digital art. Because the blockchain prevents data from existing in two places, an NFT on the blockchain guarantees that only one copy of a digital artwork exists. This makes it like investing in physical art, but without the drawbacks of storage and maintenance.
NFTs can be used in a variety of ways. Ultimately, they are a way to transfer ownership of anything that can be represented by data. This could be the deed to a house, the broadcast rights to a video, or an event ticket. Anything that is even remotely unique can be an NFT.
12. Logistics and supply chain tracking
Using blockchain technology to track goods as they move through a logistics or supply chain network can have several benefits. First, communication between partners is facilitated as the data is available in a secure public ledger. Second, it provides more security and data integrity, as the data in the blockchain cannot be altered. This means logistics and supply chain partners can more easily collaborate and be confident that the data they receive is accurate and up-to-date.
13. Secure networks for the Internet of Things
The Internet of Things (IoT) makes our lives easier, but it also opens the door for malicious actors to access our data or take control of critical systems. Blockchain technology can provide greater security by storing passwords and other data on a decentralized network instead of a central server. It also provides protection against data tampering because a blockchain is virtually immutable.
14. Data storage
Integrating blockchain technology into a data storage solution can provide greater security and integrity. Because data can be stored in a decentralized manner, it is more difficult to hack into the network and delete all of the data, whereas a centralized data store may only have a few points of redundancy. It also means better access to data, as access does not necessarily depend on the operation of a single company. In some cases, using blockchain for data storage can also be more cost-effective.
15. Gambling
Gambling industry can use blockchain to provide multiple benefits to players. One of the biggest advantages of running a casino on the blockchain is the transparency it offers potential customers. Since every transaction is recorded on the blockchain, bettors can see that the games are fair and the casino pays out. In addition, when using the blockchain, there is no need to provide personal information, such as. B. A bank account, be specified, which could be a hurdle for some. It also offers a workaround to regulatory restrictions, since people can play anonymously and the decentralized network is not vulnerable to government shutdowns.
Blockchain is in its infancy
Blockchain technology has only been around for a dozen years, and companies are still exploring new ways to use the technology to support business operations. As the amount of digital data we use in our lives grows, so does the need for data security, access, transparency and integrity that blockchain can provide.
