Lemme answer for your question -
1. White hat seo is the type of seo that does not look like SEO.
2. Most of the white hat links sends traffic to your site. In 95% case - if a link is sending traffic to your site then it is a white hat link.
3. White hat seo is the type of seo where your site get mentioned on a page "that actually adds value to your site and that page".
4. White hat seo is the type of seo where you dont make a link yourself but someone really liked some part of your site and willingly talked about that part of your site on his site. (Big companies fake this thing but still their each link will look like providing value to the community".
5. Web2.0s/article directories/pdf/bookmarks/each_and_every_service_being_sold_on_web - none of them are white hat.
If you did signup on some web2.0s and added articles on them and got a link from them to your site, then this is not white hat. They do not add value to the community. They do not look like made by someone who really wanted to talk about your site. Same thing happens with most of the link types.
Its really hard to do white hat seo. Takes a lot of labor. If you outsource to someone then none gonna do that for less than a couple of xxxx$ atleast.
Ppl always do white hat seo in a way that it look like "links are not made by site owner for seo purpose". Smart ppl fake their seo in a way that it looks white hat seo.
LTDR - u can not do white hat seo. You can only fake it. Though it brings same results as white hat so yes. White hat is possible.
