During his last trip to London, Andreas M. Antonopoulos paid a visit to three CoinScrum events. The video below is a full seminar in UCL: Consensus algorithms, blockchain technology and bitcoin”. A fantastic, down to earth explanation.
It was also announced before the presentation that UCL is launching a Blockchain research centre.
