So theres two decentralized markets competing now, Openbazaaar and Openmarket, but it looks like Openbazaar cant be used to dnm stuff anymore since it now runs on UDP and Tor is TCP based.
This one runs on "raft protocol", it appears to be TCP-based, the github page for it has a neat interactive visualization.
The github for Openmarket has alot of screenshots of it, its no dnm replacement but it would sure as hell beat waiting on agora to open up for the 45mins a day we're allowed to transact.
Cool, but it's not designed to work over Tor and adapting RQLite to work over Tor is not a trivial project. One of the problems with a decentralized system like this is that when the main node is down, clients must be able to discover and connect to one of the replicas - otherwise the decentralization is meaningless. This means that each person running a replica server (vendors and volunteers, probably) would have to also host a hidden service. While this is not impossible, it would add a level of technical and legal complexity that is most likely beyond what most DNM folks would wish to deal with.
