If you are interested in understanding what IPFS is, these 2 videos are the quickest way to get a high level view. At about 20 minutes each the first one shows you how it works with actual examples which is great and the second one is a clip from Devcon2 in Shanghai where it gives a good insight into what it is and what it does from a non technical point of view. By non technical I mean there is no code involved but it’s still technical in terms of the words used.
