Episode Details

Stephen P. Williams, author of Blockchain: The Next Everything, talks about bitcoin, cryptocurrencies, and blockchains. In this interview, I ask him:

• What is a blockchain?


• Is each bitcoin transaction really consuming 30-USA-households worth of electricity?


• What's the difference between proof-of-work versus proof-of-stake?


• What's the promise of Etherum vs. Bitcoin?


• What's blockchain's killer app? What what's the next low-hanging fruit?


• Why should painters love the blockchain?


• Why did someone pay $170,000 for a digital crypto kitty?


• Why is Williams bullish on Ethereum and Litecoin?


• How are dapps (distributed applications) going to impact us? See the state of the dapps that Stephen Williams mentions.


• What does a self-sovereign world look like?

Around 35 minutes into the interview, we discuss an interactive McKinsey matrix about the blockchain industry. It's worth seeing the matrix (or to watch my YouTube video about it).

For those who don't see how this relates to travel (my normal subject), it's that cryptocurrencies and blockchains have the potential of disrupting everything, including the travel industry. 

One of WanderLearn's top patrons, Kathy Kennedy Enger, asked me to draw attention to Health Access Sumbawa. I am happy to promote this remarkable nonprofit. In 2014, Jack Kennedy founded the organization to bring malaria control and healthcare to remote, impoverished communities. It started on the remote island of Sumbawa, Indonesia. Since then, it's expanded thanks to generous donations. Visit their website to learn more and to donate: https://healthaccesssumbawa.org
