So how does this compare with quilt? From what I see

1. Quilt is for profit while Dat is non-profit.

2. Dat has ~20 datasets that are public Quilt has 50+ that are public

3. Dat is on a shared network while Quilt is hosted on a centralized server

4. Both of them offer version control and hosting. Quilt has private hosting for a fee. Dat seems to have only public hosting

5.Quilt is funded by YC. Dat is funded by non profits.

6. Quilt has a Python interface while Dat has one in Javascript

I understand who Quilt is targeting but I'm having trouble understanding who Dat is targeting?

I'm one of the creators of the Beaker browser[1] and the reason we use Dat is that as a p2p protocol, it offers a lot of neat properties, including making datasets more resilient. As long as one peer on the network is hosting a dataset, it will be reachable, even if the original author has stopped hosting it.

I won't speak authoritatively on behalf of the Dat team, but I believe one of their goals is to make it difficult for public scientific datasets to be lost, and data living on a centralized server is particularly vulnerable to that.
