RE: l0k1 Witness Update March 29 2017
Definitely not building on graphene, though it is pretty awesome. I came up with the idea of using some kind of blockchain/distributed system to compensate people providing routing services like Tor (the reason Tor doesn't have them is the lack of a scheme that decorrelates the payment and the traffic), back in about June 2013.
I didn't really understand how blockchain mining systems are a random distribution of new tokens that well back then, but steem made it blindingly obvious. I have many variations of schemes to allow the anonymisation of the payment for this traffic, though I need to get back to working on it and actually implement it.
Hopefully soon. And since I got my witnesses sorted, maybe I should sit down and redo the Go tutorials and learn how to program in that language.
