There is no leverage on AtomicDex, and each trade is actually executed as an Atomic Swap. It is a nice project for the average Joe looking to buy some Altcoin, but it’s not practical for power traders.
Yeah, there is no leverage trading on AtomicDex, but you are saying that you want to use some new blockchain, so there is no way for this to work as fully atomic swaps, and we probably need to trust some third party for this swaps, and that is not trustless.
No no, you would do the normal fully trustless Atomic Swaps. The 'some new blockchain' construct just asserts that you actually DID go through with the Swap.
You are right, one way to do this is to have a centralized 3rd party that judges whether a Swap was executed.
But there is also the other way, which is to have a fully seperate blockchain that ALSO observes the BTC chain.
That is the participants in the Tradechain also run the Bitcoin chain, and when somebody claims to have executed an Atomic Swap, they include a pointer to the true Bitcoin TX as proof of that. Everyone running the Tradechain only accepts that "I did swap" claim only if their local Bitcoin chain state includes that Bitcoin tx.
The Bitcoin chain is oblivious of the Trade chain, it only sees the normal Atomic Swap transactions.
But the Trade chain is not oblivious of the Bitcoin chain: Certain types of "transaction" (like the claim to have gone through with a Swap) are validated against the Bitcoin chain state.
doing leverage with other altcoins is a stupid idea in my opinion.
Fair enough; but the upside of leverage/derivatives is tighter spreads and more liquidity in general, even if one does not use leverage.
