Following last year’s hugely successful æternity Universe Two, the æternity Universe Three conference will be a melting pot of engaging, knowledge-sharing workshops, panel discussions, and networking opportunities at every step.
Specifically, æternity Universe Three will focus on the latest developments and quantum leaps in DeFi, Governance, DAO, and cutting-edge protocols like Hyperchains. Moreover, it will focus on the ever-burning questions of scalability, interoperability, security, privacy, and blockchain technology.
The æternity Universe Three goal is also to engage the community and the æcosystem supporters alike in an educational, networking, dinner, and party event that includes direct communication with the Founder and key members of the æternity æcosystem. We support attendees to interact in a smaller circle and learn about the evolution and progress of our technology during the conference.
