The situation with Ethereum is very poor. We are waiting when his problems with ddos & next hardfork will be solved. We need his stability to launch.
Is this project in anyway dependent on Augur? Is there a point at which Ethereum instability may force you to consider a different platform?
Nope. About Ethereum: yes, if Ethereum will not be more stable we will think where to move Inchain.
Any suggestions?
Maybe Lisk? But I don't know if it meets all your technical criteria. Lisk is a backup solution considered by Iconomi team.
Stratis would have been an intersting choice if it had been a bit further along.
Awesome, glad to see more and more people realize the potential of Stratis platform, but their beta released will be november, it is too late for Inchain. I did the Chinese translation for both Inchain and Stratis project. I will be very happy if they cooperate.
For lisk platform, I can't see they can handle Inchain, such awesome project. I recommend OP stick with Eth, Eth will have hard fork next Tuesday, everything should be smoonth after the HF.
