Grin council member Jasper van der Maarel gave this excellent presentation on Mimblewimble and Grin at Bitcoin Wednesday on 5 December, 2018. It’s a very strong introduction to the technology behind the anonymous-by-default cryptocurrency protocol.

This talk was held at Circl, the Sustainability Pavilion at ABN Amro Bank’s Amsterdam headquarters. He also gave this interview right before the event.
