Removing the Waste from Cryptocurrencies: Challenges and More Challenges

Bram Cohen (https://twitter.com/bramcohen) (creator of BitTorrent) will be speaking on the challenges of removing the waste from cryptocurrencies:

"Expending electricity on unproductive work is inherent to Bitcoin's security. Multiple approaches to eliminating this have been proposed, none of which solve the problem satisfactorily, and are usually unusable, insecure, or completely fallacious. I'll explain what Bitcoin at core is, why and how much waste there is in it, what approaches to removing that waste are, and how they fail."
