What is "Blockchain"?



The Blockchain technology is mainly known because the digital currency "Bitcoin" is based on it.

But what exactly does Blockchain mean?

Blockchain technology allows for a decentralized accounting ledger . That may not sound exciting, but it enables some interesting applications.

As a key application, a central authority can be replaced by a decentralized Blockchain system. The Blockchain system has the same level of reliability and lower costs.

Instead of a bank controlling monetary transactions, for example, the decentralized Bitcoin no longer needs a higher authority and nevertheless works tamper-proof.

Other possible applications include real estate land registers and other central registers for assets or documents.

While the cryptocurrency Bitcoin (Payment Tokens) has already gained widespread recognition, most other Blockchain use cases (such as Utility Tokens and Asset Tokens) are still at the very beginning of their realization.

Reason enough to learn more about this exciting new technology!
