I disagree as what looks more suspicious, a computer with tor on it or a computer that has nothing on it because tor is on your flash drive?

Avoiding escrow isn’t really possible unless you somehow live in a perfect world without bad actors. I recommend doing some digging into how different defunct darknet markets have utilized escrows and monero as even if your market does everything legally there’s still valuable leasons to learn. If you want recommendations you should look into White house market (mods it’s defunct) as their system handled escrow in a way where everything happened at the transaction level meaning the only coins that could be stolen were the exact transaction ammount.

Effort? What effort? Putting a bunch of sugar into juice and letting it sit for a couple of months takes almost no effort.

Seeing how easy homebrewing and how well documented it is online…

Silk road is long gone but there are a plethora of other similar markets. Just like any other service in demand when one gets shutdown three more pop up in it’s place.

A federated marketplace could be interesting but there are some fundamental issues that would need to be addressed.

If the vendor and vendee are on different instances how will payment be securely transmitted? What if there is a dispute, which instance Admin would have final say? Will the instance operator get a cut, if so how does that work? What’s stopping my competition from opening an instance to check my stock level? What if I want to buy multiple items that are on different instances, do I have to check out on each instance?

If you can iron out the kinks this idea could make a lot of sense as a DNM as there wouldn’t be a centralized server to shut down and being FOSS would allow for auditing of the marketplace which just isn’t possible currently.
