🇬🇧 *Pragma London*
Pragma London took place at Christchurch Spitalfields in London on March 14, 2024, and was an in-person summit for builders and leaders in the web3 ecosystem. Watch the full Pragma London playlist here: https://youtube.com/playlist?list=PLXzKMXK2aHh7rvaHBM14peT1TwI3QX38p&si=MzGrEYwYjxSQFiFM

ETHGlobal's Pragma series takes place in cities around the world, and is designed to be a different kind of event. Pragma is a one-stage conference with founders-only on stage, bringing together a small group of curated attendees and speakers to discuss the future of web3 and reflect on the past. Ever since we first introduced our new event series Pragma in Tokyo of the spring of 2023, we have been fostering a curated, global community of individuals who deeply care about web3.
