So I really like what Nucleus and Blackbank have done to whether the 0-day Tor storm the other markets haven't.
Blackbank, while more glacial than the turtle in the race between it and the hare, is slow and steady as always and reliable to place multisig orders with.
On the other hand, Nucleus has implemented rolling .onions in order to give DDOS attacks 20% efficacy. Unfortunately... still no multisig.
So while both are somewhat "up" right now, its not the perfect solution. I've seen a lot of discussion about the future of DNMS and I think a combination of what Agora has done with cycling their physical location, Nucleus's cycling of .onion location, and Blackbank's arcane ability to stay up and great multisig implementation would create the better DNM of the future.
What else besides 2-FA, enforced PGP, multisig, rotating .onion and phsyical location would make "the DNM of the future?"
Frequent, or at least periodic, communication from site administrators would be nice. Instead of having to guess whether the site is being attacked or is under maintenance
