This is first test how decentralized this exchange is. If it will somehow cease to exist then is not that decentralized.
I don't think that we have any truly decentralized exchanges as of yet. I do suspect that in time we'll have an exchange that has no entity controlling its development, maintenance etc. Hopefully some sort of open source exchange in which all users are in control of their own funds and the trades that they execute. A lot of DEX's currently are more like hybrids between a centralized and a decentralized exchange, mostly around the fact that they don't hold users funds.
I have an obvious conflict of interest here, but I've spent the last 4 years working on the Blocknet, which meets the requirements for a completely decentralized exchange.
Quick summary:
To decentralise an exchange, at a minimum you have to decentralize the four core functions of an exchange:
- capital storage
- order broadcast
- order matching
- settlement
Over and above that, you certainly need:
- open source code
- no company or central legal entity
- globally distributed community of developers
- no entity with control over trades
- no central control over listings
We've done all of this.
