Ideas for bisque-like exchange based on graphen tech

One of the biggest problems i met in crypto world is buying cryptos with fiat money especially the problem of trust And as governments cracking down on exchanges for many reasons the need is dire for decentralized exchange that solve the problem of trust 

 

The problem with bisque is that it work on tor - which is blocked in many countries (including my country) and it use only bitcoin which is slow and take alot of transaction fees

 

A graphen based blockchain would solve that problem with a smart contract system that requires collatoral from both the buyer and the seller and automatically release the amount when trade is confirmed at very low fees just like bitshares blockchain

 

I think such a system is easy to be made and would solve many problems and help overcomming FUD from governments cracking down on exchanges

 

I hope some one get intersted in such idea and develope such a platform

 

If you know a project that have such features or able to help achieving this idea please share your ideas
