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.
