Should the questions I'll ask be too basic please drop me a kind note and I will be more quite or ask my questions on other places. Today I studied Chrstian Deckers nice work about duplex micropayment channels ( http://www.tik.ee.ethz.ch/file/716b955c130e6c703fac336ea17b1670/duplex-micropayment-channels.pdf <https://www.google.com/url?q=http://www.tik.ee.ethz.ch/file/716b955c130e6c703fac336ea17b1670/duplex-micropayment-channels.pdf&sa=D&source=hangouts&ust=1520200459037000&usg=AFQjCNG3ZwxZzV6e3VYlLpemzn0ZCUIv-A> ) I am wondering what was the rational for the lightning spec ( https://github.com/lightningnetwork/lightning-rfc ) to go with the revocation key system instead of the solution by Christian Decker to the problem? I understand that the revocation system was already in the whitepaper and at the time of writing the whitepaper the work by Christian Decker wasn't out yet. But I guess this will not be the entire reason. To me the key revocation system seems pretty complex to handle. In particular as Rusty also mentioned on his article (c.f. https://medium.com/@rusty_lightning/lightning-watching-for-cheaters-93d365d0d02f ) that already in the white paper people knew that potentially a third party observing service to detect a cheater is needed. This seems to me like a big drawback. So what have been strong arguments to go with the revocation system? On a side note I would like to state my respect to you: The lightning network (in combination with bitcoin) is really the most beautiful piece of technology I came across since I learnt about TCP/IP. Great work everybody for creating such an amazing technology and bringing together all those beautiful ideas. I am very confident that this technology will become history. best Rene -- www.rene-pickhardt.de <http://www.beijing-china-blog.com/> Skype: rene.pickhardt -------------- next part -------------- An HTML attachment was scrubbed...
