Blockchain is a decentralized technology or distributed ledger that stores data about all transactions in chronological order and transparently. Each block in the chain contains a specific number of transactions and is linked to the previous block by cryptographic methods, which ensures data integrity.


The technology was first introduced in 2008 as a response to the financial confidence problem in the description of the cryptocurrency Bitcoin. Since then, blockchain technology has evolved beyond its original scope of application and is being used in various industries.

Areas of application

Blockchain is used in numerous areas including financial services, supply chain management, healthcare, real estate, and more. In industry, it can be used to improve transparency, track the origin of materials and increase efficiency in production.


The key benefits of blockchain technology include increased transparency, improved security, and reduced fraud risks. The decentralized nature of the technology also minimizes the need for centralized intermediaries, which can lead to cost reductions.


Challenges include scalability, high-energy consumption for certain types of blockchain (such as Bitcoin), and legal and regulatory uncertainties. Solutions include the development of more energy-efficient consensus algorithms and the creation of a clear legal framework.


A specific example of the application of blockchain in industry is the use of a B2B retailer portal for the secure and transparent documentation of supply chains. Companies can see in real time when their products are and who has handled the products.


Blockchain is a transformative technology that can revolutionize numerous industries through its ability to securely and transparently document transactions. Despite some challenges, the diverse range of applications offers significant benefits for companies.
