I feel very privileged to have been able to meet and speak with Vitalik Buterin in London recently.
The occasion was the recent Ethereum Meetup, superbly organised by Stephan Tual, Founder Slock.it & Ursium & Former CCO Ethereum and Vlad Cealicu, CTO & Co-Founder CryptoCompare.com
Vitalik gave the most entertaining and interesting presentation on the theme:
"Blockchain and Ethereum Security on the Higher Level"
Update: Vitalik Buterin's presentation from the event is now available at:
