What previous attendees have said about Open Protocol
A lot of true believers and not many tourists. I’ll be returning.

There is a gap in the market for a great blockchain conference and meetup for leaders in London. The UK and EU regulatory frameworks are moving in positive directions which will allow the market to flourish. BACKED VC HQ is in London and we decided its time to make a mark on our home turf and invite our incredible blockchain network to the greatest city in the world. ;)
Open Protocol was spun out of the Slush technology conference in Helsinki as a standalone event. The inaugural one in 2022 was the largest Web3 event in the Nordics to date with over 15% of the entire Slush population applying (1800 applicants) to attend. In total Open Protocol had 1690 applicants, with 600 attendee tickets, 40 speakers and 13 talks.
