    Protocol Berg v2 was a two-day technical conference targeting an audience of protocol/system/network engineers, decentralized-infrastructure administrators, researchers, and other curious minds. Protocol Berg v2 aimed to bring distributed technology ecosystems together to exchange concepts and technology, talk about shared open problems, and learn from each other.

    Topics covered by the event mainly revolved around consensus protocols, distributed virtual machines, peer-to-peer networking, decentralized infrastructure, open-source governance, and protocol research.

    Tickets were free, as in free lemonade. All attendees had to adhere to the event's Code of Conduct.

    Protocol Berg v2 was a donation-backed, non-profit event. Therefore, there were no sponsors.

    4. About the Host

    The Department of Decentralization is a collective of people from various crypto, decentralization, and blockchain communities in and around Berlin. The group assembled in 2018 to organize events such as ETHBerlin3 4 5 6 , Protocol Berg7 , and GoerliCon9 , and has been active since.

    The aim is to be an agnostic vehicle to drive adoption, educate newcomers, and raise awareness of the challenges and benefits of decentralization and open-source software. Currently, the Department is primarily run from Berlin. The collective is composed of around a dozen members who contribute voluntarily.
