Blockchain is something that we are accustomed to cryptocurrency and Bitcoin. But the truth is this innovative technology is capable of doing more than just facilitating a tamper-proof financial transaction. Much much more. In fact, we have only scratched the tip of the iceberg. By utilizing blockchain technology to its full potential, we can create more fairness and transparency among various sectors as well as save a lot of time and money. In this article, we will look more into this marvelous technology and its various real-world use cases.
What Is Blockchain Technology?
Blockchain technology is a decentralized, public ledger that records and verifies all the transactions that take place in a network. One of the most important use cases of the blockchain is in the world of cryptocurrency. A blockchain performs functions that are similar to that of a spreadsheet that we use to enter and store data. But unlike the spreadsheets, once entered it is nearly impossible to change the values present in a block. That’s what makes the blockchain so secure and transparent.
The key features of blockchain include
- Decentralization
- Immutability
- Distributed Ledger
- Security
- Smart Contracts
- Transparency
- Consensus Algorithm
Real-World Use Cases Of Blockchain
Blockchain technology has several real-world use cases associated with it. In this section, we will look into a few of them. They are
Smart Contracts
Smart contracts are computer programs that have the ability to automate transactions that take place on a network. They work much like real-world contracts and are excellent for eliminating middlemen. Smart contracts can also provide a level of security and accountability to all the people involved in the transaction, which is not possible when you’re using a traditional contract. These days, they are gaining popularity, especially among government, healthcare, and other industries.
Healthcare
In the healthcare sector, blockchain has a lot of applications. Out of them, the most notable one is the patient data management. Whether it is to store a patient’s record, social security number, or bank account number, blockchain provides a secure storage space for all this. This prevents any unauthorized personnel from accessing the patient’s data. It does not end there, there are also numerous other applications like storing research materials, and supply chain management to prevent any usage of counterfeit drugs. Blockchain technology also allows doctors to view the details of patients from a remote area, without needing to worry about anyone trying to steal that sensitive data from them.
Logistics & Shipping Industry
By creating an immutable and transparent record of all the activities surrounding the supply chain, it allows companies to track their products throughout the entire supply chain and verify their presence at each step. It also significantly reduces the number of fraudulent operations that may occur in this sector. Without the need for a third party or middleman, most of the processes associated with the shipping can be automated thereby saving a lot of time and valuable resources.
Government
Blockchain has a huge potential when it comes to various government operations. With its immutable secure environment, blockchain will be able to create records and documents that are literally near impossible to tamper with. As we already know, blockchain can bring much-needed transparency between the government and its citizens, which will help in boosting their trust. With blockchain, everything is stored on secure blocks in a network. This eliminates the need for paperwork and record-keeping further eliminating the possibility of any fraudulent activity taking place.
Internet Of Things
Blockchain technology can revolutionize IoT by making data more secure, transparent, and efficient. In blockchain, there is a method referred to as the cryptography. This is how it secures the integrity and immutability of a data packet. With this security, a blockchain is essentially creating a tamper-proof platform that allows instantaneous exchange of data. Also, as there is no need for intermediaries in blockchain, it eliminates the delay and the associated cost. That way, you can transfer data to other devices much faster by using trusted nodes to verify your transaction in as little time as possible.
Finance
Blockchain technology is on the way to revolutionize traditional finance in many ways. By eliminating intermediaries, cross-country transactions can now take place without any additional fees or time wastage. Also, it facilitates a faster verification of transactions, which is more cost-effective than the one associated with traditional transactions. All the transactions that took place in a network can be viewed by all the participants providing enhanced transparency. There is also the fact that the blockchain algorithm is continuously on the lookout for any fraudulent patterns or anomalies that are associated with a transaction. It helps prevent any and all fraudulent activities that may take place in the network.
Media
Blockchain’s main highlight is its capability to record every transaction and interaction that takes place in a network. If this is implemented in mass media, it could help a lot in building trust between advertisers and other parties. Not only that the creators can also sign on their numerous works on social media, which greatly helps in winning various copyright disputes. Blockchain also allows various fans and investors to hold a stake in content. There is also a way for you to sell your works to your fans, which allows you to create your own revenue streams.
