That said, I believe deepening the relationship between XMR and LTC would be super positive. And for LTC to be able to claim to have performed both the first ever atomic swap AND the first ever atomic swap with a non BTC codebase crypto would be killer. And I think the liquidity a LTC/XMR atomic connection would provide mixed with it's novelty would benefit both communities.
The first ever 'atomic cross-chain transaction' was between Burst and Qora on May 17, 2015. Extremely efficient implementation was used, based on this AT Turing complete smart contracts implementation (2014, before Ethereum):
Automated Transactions (AT) is a technology created by CIYAM Developers which provides "Turing complete smart contracts" for any blockchain that implements it (
http://ciyam.org/at).
Recently the AT developers produced a Crowdfund application that only requires 25 machine code steps (which is ridiculously small) and that is running on a blockchain now (the Burst blockchain). This is the most efficient Crowdfund application in existence - not only is it incredibly efficient but it is also 100% decentralised!
Although we are having troubles with getting any attention (hopefully some smart marketing people will notice this project and consider contacting us) we have already achieved "two world firsts" which we intend to follow up with more ground breaking ATs (which are under development now).
#1 - The world's first completely decentralised Lottery (i.e. no website and no central control) was launched in January 2015.
#2 - The world's first completely decentralised Crowdfunding application (i.e. no website and no central control) was launched in February 2015.
A couple of great tools for those keen to develop their own ATs can be found here (thanks to @burstcoin):
https://github.com/BurstProject/ATAssemblerhttps://github.com/BurstProject/ATDebuggerThe undisputed king of atomic swaps is jl777 (he did them in 2014) his BarterDEX has done well over 20K swaps now, most using spv tech so you don't even have to download any blockchains, and if users are prepared to time-lock a KMD deposit they can be 0-conf too. BarterDEX has already done test 'etomic' swaps between KMD and ETH even.
It's absolute BS that Charlie Lee claims any credit for doing a few manual swaps with LTC, eventually the word will get out about BarterDEX, and people will naturally ask "why did Charlie ignore BarterDEX for so long?"
Holders of assets like DEX have already been paid 2mil USD from fees so far, just from the test alpha stage.
