I have little theory that some markets are operated by the same person. Like sr3 = crypto market as you can see here: /r/DarkNetMarkets/comments/2modbl/andromeda_seized_today/
So, i guess that OASIS market have same history because they become from dust in exactly same time as TRDM changed their source codes -- /r/DarkNetMarkets/comments/3xe1ck/how_do_you_like_our_new_system_no_more_bitwasp/ and compare date of that announcement with date of creation of this user /u/oasismarket
Now they're propably doing an exit scam becase TRDM is now offline for more than week. But as you can see in archieved version, very similar design ... only layout is little different.

Obviously they focus into new brand. Hope i'm wrong about this.
All the DNM's are run by the NSA. I have proof!
