GBB x BBW Open Mat is a Belgrade Blockchain Week side gathering. Hosted by Nemanja Petrovic, the session swaps panels for the tatami with open rolling for builders, founders, fighters, and Web3 attendees.
The format is open to all levels, from white belts to black belts. BBW attendees can join even without jiu-jitsu experience.
Participants should bring a gi or rashguard/no-gi kit, mouthguard, and water. Loaner gis are available on request while supplies last.
