This project is exciting. It is on ethereum like Augur. They are adding payment channels to reduce blockchain bloat.
Haha, no it isn't.
Haven't you understood anything I've written, in the whitepaper or on the blog?
Namely http://www.truthcoin.info/blog/contracts-oracles-sidechains ?
Does groupgnosis not have the oracle yet?
I'm sure it wouldn't be hard to re-use augur's code.
They are going to be the first to have betting off-chain it looks like.
The oracle is the most important, and most fragile part. Just "reusing" it is very dangerous.
