Trademark Protection For Blockchain?

It lies in the nature of the blockchain technology that the control and securing of blockchain transactions have a non-proprietary character. The decentralisation of the system shall furthermore guarantee the stability and consistency of this decentralised trust "sphere". Starting with this characterisation, it seems at first sight to be paradox to openly think about the question, whether trademark rights could play a valuable role in the "blockchain community".

However, as commonly used terms, such as "software", "Internet", "social media" or "crowd funding" and the like, generically describe specific methods, technologies or systems, they are public domain and thus free for anyone, without the possibility of monopolisation through trademarks.
