Is there still no way to make an offer and have it available for others to view when you go offline?
I understand this is very difficult to do in a decentralised manner, but I feel this problem is halting Dark Exchange's community growth.
It is quite clear that when people log on only to find themselves online, thus no offers, it makes it look like you have entered an empty hall expecting a bustling market. If this happens I believe more people will use it.
My suggestion is to have some kind of 'pass-the-parcel' technique where a node locally stores tgeir offers, and before it logs off it passes those offers to any online nodes before logging off, and thatnode does the same thing, and so on.
When a node comes back online, it can reclaim those offers so that it can broadcadt them itself.
Any thoughts?
