I hope that SR 3.0 will soon be launching with P2P technology.
Both SR1 and SR2 used a p2p marketplace and the only part that was not p2p was the UI and the escrow
The forums were centralised and played a big part in people both disclosing too much information about themselves and behaving as though other forum users were their personal friends talking in a private room. A lot of people made themselves far too visible on the forums and undermined some of the anonymity the platform itself was designed to allow them.
It was kind of scary watching how quickly people were willing to trust others largely on the basis of their forum personas and how willing they were to believe that what regulars posted was the truth - even after they'd been reminded many times that it was inevitable law enforcement was not just watching but likely actively posting on the forums.
A real danger of trying to foster a sense of community around the dark markets is that it makes social engineering relatively easy. It's much easier to be undercover online than in real life because there's no risk of someone recognising you. You can live your normal day life and be someone else entirely online with no risk of bumping into an old high school friend or someone you've previously arrested while you're undercover.
Do we know the name of the person responsible for SR2? I can't seem to find a credible article with a mentioned name/location/history and most importantly IMO their connection to the original SR.
Many people believe that DPR2 was StExo - the guy who never shut up about being a major money launderer on the SR1 forums.
The mythology is that there were mechanisms in place for new people to take the reins if people were caught. Defcon took over when DPR found it "necessary" to disappear (from memory, this happened when the SR forum mods were arrested). Yet it would have been really stupid to set it up in a way that someone knew who their successors were going to be, as they could obviously disclose that information to law enforcement.
There was a whole lot of stuff going on immediately after the fall of SR1, with vendors and users alike believing they should have some say in who took the reins (which is kind of like your average small drug buyer thinking they should have a say in who heads a Columbian drug syndicate).
Which are the best black market forums into the Deep Web nowadays?
You pretty much have to assume that any which are talked about publicly are under active investigation at the moment. The Europol statement mentioned two which haven't been taken down
yet, but which are clearly under investigation. Any service which says it's totally secure is full of shit because none of them can guarantee that. Nobody knows at the moment the full extent of the information law enforcement has got from this operation and how many more services it may affect. New markets will probably spring up overnight as they did when SR1 went down, and they'll sucker in desperate users and run with the money once again. Don't be in too much of a hurry to find a new dark market right now - see how things shake out over the next few weeks.
