Debate Series #3: On Immutability and Hard Forks

This is the 3rd event in our debate series. This event will focus on the topic of immutability in the context of cryptocurrencies. What is it? Why is it (or is it not) important? How can we protect it?

Because the topic is itself controversial, we will use the event to follow up on our previous debates (#1 (https://www.meetup.com/BitDevsNYC/events/228376890/), #2 (https://www.meetup.com/BitDevsNYC/events/229692528/)) on hard forks and decentralization. Now that we have some preliminary data to analyze (ETH/ETC netsplit), attendees will be given the opportunity to voice their opinion on the success or failure of the split in the greater context of immutable blockchains.

Feel free to post articles in the discussion section (https://www.meetup.com/BitDevsNYC/messages/boards/thread/50063304/#129525110) that you want attendees to read before the event.
