pretty sure they had their plan put together in a decentralized form a while back now mate ...
...
The decentralized market goes way back, but I don't think the services part was part of the plan from day one.
Of course they didn't come here and copy our model. Actually, just expressing that services is how they are going to make money. That's what we've been talking about - they've got $1m from investors, but no coin, so they will be running a centralized service

Would it go into SPR servicenodes? Up to devs and community to vote on it, I guess. I doubt it would be an issue as the software is opensource. A decentralized market, on a decentralized servicenode network. Interesting.
I could spend a few hours tracking down the posts I made proposing the decentralized exchange to be built on masternodes, god knows when last Spring or summer, and the subsequent inclusion of business services into DRKs roadmap after I raised it back in ~May last year.
But there is no need, we're here working on those services now and there was a big consensus last year in DRK to drop everything and just focus on the currency and going after Bitcoin.

oh, piss. I sort of remembered the dates because I was on holiday.
DRK <> BTC Exchanges
You don't actually need an exchange as such....you just need an exchange mechanism that collects inputs of DRK or BTC and matches the two at an acceptable strike point.
Bob wants to sell 1 BTC
Jane wants to sell 1 DRK (

)
Both Bob and Jane send their coins to a holding address, effectively an escrow, and when there are two equally matched transactions, they are executed.
Probably not that far removed from what Master Nodes do now with their 8 rounds.
DRK Master Nodes as decentralised BTC exchanges....make it so.......
I'm defo not trawling for the earlier references.
