Re: Atomic swap? Objection: I don't think it means decentralized coin exchange.

I think not, because you are dealing with a complete stranger- perhaps an adversary. So you must validate for yourself that you have e.g. 1 confirmation and you really can't trust any external party for that information. There is also the question of adversarial forks, so this would be the only way to guarantee you are running on the chain you think you are, and that your trading partner is not trying to use a slightly different chain. But I'm sure these services will be made available anyway, and people will use them without thinking about it 
So I interpret that it would be "possible" but potentially insecure. Well, for small amounts of less than (let's say) ~$100 (I think those make up the majority of altcoin trades) it would be a relatively "doable" solution if a swap-capable client checks various block explorers of different origin if the confirmations have happened.
You'd probably only be able to trade with other people who have the same pruning settings on their chains, but this is just a wild guess.
Interesting, but I "don't get it" for now. Could you clarify why you think the pruning settings should be similar or give me a hint where I could research?I did not know that atomic transfers were already invented two years ago. Thanks for sharing.
Which coins were used to do the transfers and why is the technology not widely used today? This is a breakthrough and no one is giving it any attention or giving the developer any recognition.
The coins that already can be used for atomic swaps are Burst and Qora. At least the Qora client has even a GUI option for that (see this article).Which coins were used to do the transfers and why is the technology not widely used today? This is a breakthrough and no one is giving it any attention or giving the developer any recognition.
The reason I think it is not widely used is that both coins share a relatively similar codebase (they are Java coins inspired by NXT and use a smart contract platform called "Automated Transactions" for the atomic swap implementation) that is pretty different from the standard "Bitcoin clones" and Bitcoin/Script coins need an alternative implementation. Burst and Qora never were among the "top altcoins".
I think also the creator CIYAM deserves more credits for his breakthrough implementation. His solution is based on a concept invented by Sergio Demian Lerner and improved by Tier Nolan but it's the only implementation I know that is usable by non-technical users.
