# Root Entropy Ceremonies There are 3 primary types of [Root Entropy](glossary.md#root-entropy-re) derivation ceremonies: * **Local**: where all cryptographic material, including the Operator Keys, Location Keys, and the Root Entropy are all generated during a single in-person ceremony * **Hybrid**: where the Operator Keys and Location Keys are generated separately prior to the in-person ceremony where the Root Entropy is generated * **Remote**: where all cryptographic material is generated in a decentralized manner, remotely.
