Hi Maximilian,
It’s an interesting idea. However, where we excel in storing data and running IT workloads privately, there are parties that have evolved more than us over time in the decentralized exchange domain. One of them, by the way, is Stellar. They are not doing atomic swaps to achieve this but have their own mechanism, defining assets and trustlines and exchanging between assets on their blockchain network. A thing that we missed in our technology was the management of order books: in short, we were able to execute deals with other blockchains and cryptocurrencies residing on it (using indeed atomic swaps), but we were so far not able to match offers coming from the different buyers and sellers. A thing that is essential in a DEX, and that Stellar has dealt with in a marvellous way, with their StellarX setup. By the way, StellarX will be one of the exchanges that can be used to trade TFT with other cryptocurrencies, starting with XLM, but also other cryptocurrencies and stable coins (which is basically fiat money in a crypto form).
So yes, we have part of the technology, and it might be reused at some point in time. But I think in the short term collaborating with and hosting blockchain projects that already implemented DEXes is a better strategy for the time being. My 5 cents.
