TakeItEasy, WebRTC is to allow peer to peer connections directly in the browser, to enable a trustless coin, otherwise we wouldn't discuss on bitcointalk if we don't want trustless coins.

The blockchain is not recording any of that information, you are referring. In the blockchain, nobody records the IP, geoip location (which is not even precise it has an error of about 400 km), username, etc resolution. If you want to mine anonymously (because this is what you were referring, you can use a VPN). One of our devs, was also working on an anonymous VPN miner you can access at https://WebDollarVPN.io Moreover, if you mine in a mining pool, you are pretty much anonymous to the entire network.
