Blockchain explained: a game changer for many industries.

You can think of a blockchain as a decentralized database, essentially a distributed notebook. Each transaction is recorded as a data block in a chain on all participating computers. These chains cannot be altered, making them practically tamper-proof compared to traditional centralized databases. In English, this is called "Distributed Ledger Technology".

In the blockchain network, all assets can be stored, tracked, and traded. Tangible assets like cars, houses, or money, as well as intangible assets like patents, copyrights, certificates of ownership, and more. Blockchain is transparent, immutable, secure, fast, and cost-effective, as it eliminates the need for intermediaries like notaries, banks, travel agencies, or other middlemen.

The blockchain technology procedure is highly versatile and can be applied across various sectors.

• Decentralized finance (DeFi): More and more financial companies are integrating blockchain technology into their existing business models and providing financial services through a decentralized platform. For example, PayPal now allows the buying, selling, and holding of cryptocurrencies. Additionally, transfers between individuals and businesses can be conducted using cryptocurrencies.

• Supply chains: Where does your coffee come from? The food giant Nestlé uses blockchain technology in its coffee supply chain to track Zoégas coffee from the moment it is harvested in South America. Many other suppliers also use tracking for their goods to ensure full transparency, sustainability certification, and real-time tracking throughout the entire value chain.

• Identity verification: There are now various companies that use blockchain technology to verify the identities of individuals. This could make the issuance of passports, identity cards, and driver's licenses easier and more secure, as they would be tamper-proof. This also applies to certificates, documentation of ownership, asset management, origin guarantees, and more.

• Healthcare: Sensitive patient records can be stored in the blockchain and selectively unlocked – only for doctors. This ensures that all data is securely stored, so that patient records no longer need to be actively sent when changing doctors, but can be accessed directly. Information such as blood pressure values, blood sugar measurements, or vaccinations can be automatically updated in the record. Even the manufacturing and transportation of medications can be transparently recorded and tracked along the entire supply chain.

• Media and art: A major topic is also art: Genuine paintings, abstract art, or even digital art can be verified for authenticity and tracked. For example, in 2021, a digital collage by US artist Beeple was auctioned for $70 million. The artwork was stored on the blockchain and encrypted with a Non-Fungible Token (NFT). With NFTs, it is now possible to create unique digital media and assign them value. Therefore, anyone who wants to buy virtual art in the form of an NFT can rely on well-known marketplaces, such as Opensea, thanks to blockchain technology, as these platforms also utilize the blockchain.

The adoption of blockchain technology is still in its early stages. As more and more companies become fully aware of its potential applications, blockchain will continue to drive forward various industries. Additionally, cryptocurrencies are becoming increasingly integrated into regulated financial systems (e.g., under MiCA in the EU), and the transition to Web 3.0—an internet of values or an internet of things—could also become a reality. Here, you can learn more about the development of the internet from Web 1.0 to Web 3.0.

We cannot predict the further development of this advanced technology. However, the opportunities are clear: increased security, efficiency, transparency, speed, authentication, and cost reduction. It is quite conceivable that blockchain will accelerate the economy in the future.
