Uses of blockchain technology

Blockchain uses a secure and decentralized process to store electronic information. Data is stored in linked and encrypted blocks in a way that prevents forged transactions. As it’s decentralized, this means no single person is in control of the database. Blockchain works on the basis of shared ownership.

While there’s far greater depths to what blockchain is capable of, its core tenet is that the data entered is immutable and irreversible. This makes it a vital new technology for transparency and efficiency in our new age of data.

But what are some of the uses of blockchain?


Crypto is the original and most basic use of blockchain technology. By providing a transparent and verifiable list of transactions, cryptocurrency users are provided with complete security when making payments. Users don’t provide any sensitive information and fraud is at a minimum.

In particular, Ethereum makes great use of itsblockchain, with many other coins and further applications such as NFTs utilizing the Ethereum blockchain.

It’s the security of blockchain that adds such value to the emerging market of cryptocurrency. Both investors and casual users benefit from finding out about the Best Crypto South Africa has to offer.

Carbon emissions

One unusual use of blockchain is in the counting and countering of carbon emissions.

Through its accurate recording of transactions, it can be used for tracking greenhouse gas emissions across industries and nations to bring greater trust and engagement to the fight against climate change. It would give consumers a more educated view of the carbon emissions of various producers, and real-time records prevent greenwashing by companies trying to hide emissions behind subsidiaries and outsourcing.


The current global logistical process is extremely difficult to track in its entirety. The large number of logistics companies operating is unwieldly with a lot of information still hidden within paperwork, especially in the maritime sector.

Blockchain would increase the traceability of shipments globally with real-time tracking of each time goods change hands. This would reduce fraud and corruption, and support information sharing to account for disruptions elsewhere in the supply chain.

An automated supply chain would decrease major disruptions such as the ones faced in 2021 during the height of the pandemic. It also allows all users ranging from suppliers and producers to customers to have greater visibility regarding the progress of goods.


Blockchain’s applications in information storage are highly applicable in healthcare. It can be used to store medical records both securely and with permanent accuracy. Having a complete database of patient records will streamline and increase efficiency in the healthcare process.

It also gives patients complete control and security over their own medical records and ties into logistical processes by tracking drugs and other medical equipment across the supply chain.


With the fundamental concept of blockchain being decentralization and a democratic framework, it’s ideally placed to address emerging issues in cybersecurity. Any instances of misinformation can be flagged via automatic cross-checking. Decentralizing DNS helps prevent hacking attempts. Malware could be irradicated at the source.

In this age of leaked personal information and smart technology, blockchain could offer a new level of security to users among growing concerns.


Non-fungible tokens (NFTs) is a buzzword that is well known across the digital world, with its current applications being the purchase of assets such as art, film and even memes. Processed via blockchains, NFTs are wholly resistant to forgery. The owner can claim and prove full rights, an essential in the face of copyright breaches.

Content creation

The copyright protection offered by NFTs can be extended to original content creation as well. Through protection of intellectual rights, it subverts the plagiarism of content creation within a sharing ecosystem and allows creators to track their work as it passes through intermediaries.


Blockchain-based distribution of media would make every copy unique. It would also combat piracy as media would have perfect traceability. Blockchain-based decentralized media librariesakin to Spotify would ensure that artists receive the royalties they are due fairly and quicklythrough micro-payments for any media consumed.


Through its efficient and accurate information storage and tracking, blockchain applications can be extended to governmental processes to cut through the tedium of bureaucracy as well as provide an immutable means of accountability forthe promises of government officials.


It can also be used in voting. While electronic voting combats a lot of issues with voter fraud, blockchain-encryption would provide new heights of voter privacy alongside reducing the costs of outdated technology. Votes would be counted quickly and transparently, and the applications could be extended alongside implementation of blockchain in government processes to bring a new stage to the democratic process.
