Bas Wisselink


I am Bas Wisselink, and I am a speaker and educator about Bitcoin and blockchain technology.

Since 2013, I have been active in this field as an organiser, catalyst, speaker and entrepeneur.

I have a clear view of what blockchain technology can be for the world and I have written articles on the subject, engaged in debate and given many interviews.

I believe in building what helps and as such, I am a co-founder of the Nxt FoundationJelurida B.V and Blockchain Workspace.

Currently, I am a freelance speaker and advisor that designs and conducts blockchain training as well as giving presentations on blockchain.

I deal with fundamentals:

  • What *is* Bitcoin and how does it work?
  • What makes is special and unlike anything we have previously seen?
  • What are its strengths and what its weaknesses?
  • How can you use it and what uses are idiotic?

I believe this technology is interesting without any additional hype.

You can book Bas to speak, write or debate via the contact form. I promise you I will engage any audience on its own level, and can explain the basic principles of this new technology without “selling”.

I believe people should be totally free to make up their own minds. To do that, they need information. My mission is to provide that information to the best of my ability.

Twitter Threads: Private and Public Blockchains

Thoughts on “A Cypherpunk’s Manifesto”, part 3
