I wonder if a block chain could certify websites:

1. someone writes a url to the chain

2. others post a (url/hash/date time) of the output of the url

3. then people could post an image with their face and a blockchain address. could be a form of ID.



There are various groups working toward a blockchain id system including Thomson Reuters[0], and a Microsoft/Phillips-backed company Tierion[1] -- both on the Ethereum public chain.

This is what the ENS (Ethereum Name System) will be doing. In face, if you see an ICO on the Ethereum platform that doesn't use the ENS, avoid it. The ENS is actually really cool.

Although, you should probably avoid all ICO's =p
