I have been watching this atomic cross chain trading thing for a while, and it is interesting to see that you guys issue asset for this relatively old problem.
The reason that this ATOMIC was not implemented before is because it is difficult. The closest solution is as below:
https://github.com/TierNolan/bips/blob/bip4x/bip-atom.mediawikiBut this is obviously not enough for what you have planned. Considering you guys have gotten million dollars in valuation, maybe you could hire really smart guys with this money to solve it.
It will be helpful if you could give more details about this POE/POG, and convince us that it will really work as you expected. Meanwhile, ATOMIC assetholders will not get anything before it is finished and the price of ATOMIC will be totally speculating before that.
Take this as risk reminder of the challenges in ATOMIC development, and I would love to see ATOMIC could finally come true.
By the way, you could choose the MGW approach, but even though there is multi-sig, you still have to trust the gateway, which is not perfect DAC. Another possible idea is similar to DPOS, and users dynamically elect agents to handle the exchanges. If this is what you want to do, I am in.
