The blockchain and the technology behind it are on everyone’s lips – especially since Bitcoins and other digital currencies have arrived in the mainstream. There is a lot of half-knowledge about how it works, and yet the technology is often cited or used as the basis for other, new business models. But how exactly does this work?
Infographic: how the Blockchain Works

Here we explain exactly how the so-called blockchain works:
- In the initial situation, person A wants to send money in the form of digital currencies to person B.
- For this purpose, all important information of the transaction is digitally stored in a so-called block.
- The block is then forwarded to all parties (computers) connected to the network.
- In the next step, these parties confirm the transaction as valid.
- After that, the block of the said transaction is attached to the existing chain. This makes the transaction irrevocably and transparently stored and visible to all participants in the network.
- And finally the money is sent from person A to person B.
The blockchain works in such simple and yet efficient steps. It makes it possible to achieve unity in a network that is structured in a decentralized manner.
