What would you suggest deadlock?
Whose got the best innovation going in crypto today?
The best innovation would be clearly the
Atomic Cross Chain Trading (not yet implemented!)
I mean especially the part 2:
2.) Solution using specialized altchain
The previously mentioned approach can be used directly to trade between bitcoin-derived chains without special support on the side of protocol. The obvious disadvantage is nLockTime - if counterparty does not go through the trade, our funds are locked and cannot used in another trade for the duration of timeout. Additionaly, it depends on transaction replacement which may, or may not be considered standard under current bitcoin protocol rules.
Another proposal of cross-chain p2ptrade is to use specialized altchain with properties for efficient operation of p2ptrade from bitcoin chain. Additionaly, we use only single standard bitcoin transaction which looks exactly the same as normal payment (no nlocktime, no multisig, no special script).
Assuming the altchain has actual economic value to support it, it can even serve as proxy for (relatively) efficient zero-trust p2p market between fe. BTC and LTC thanks to arbitraging market makers.
Part 1 is with contracts, that's the way Ether etc. go! Means they "try".
This has some disadvantages.
- nLockTime
- other unwanted dependencies
Other coins could go way 2 , as explained, to get advanced position.
So the way 2 is better and superior!
