Datascape podcast episode 23 – private vs. public blockchains

Posted in: Business Insights, Podcasts, Technical Track

On today’s show, we welcome Adam Muise to chat with us about the ins and outs of the private and public blockchain. This is a somewhat intermediate discussion and is not an introduction to the blockchain or cryptocurrency, so if you are entirely new to this subject, it is suggested you return to this episode after reading any of the primary resources available online. During our chat we look at the two phases of the history of the blockchain and differentiate broadly between the private and the public. We look at security, privacy and net neutrality as well as questions like, “Who exactly will use my chain?” Without getting too deep into the different currencies and platforms Adam talks about Ethereum and bitcoin for the most part to illustrate his points. So if you have been interested in this increasingly vital topic and want to dive a bit deeper, this episode is for you!

Key points from this episode:

• Adam’s history with blockchain and its two phases.
• Differences between private and public blockchain.
• Why participate in a bitcoin node without mining?
• Deciding between public and private blockchain investment.
• Reasons to keep your purchasing history private on the chain.
