This section introduces the key concepts behind drand. For information about consuming the randomness from a drand network, see the Developer's Guide, or for help running a drand network, see the Operator's Guide.

• Overview describes drand's main goals and gives an overview of the problems it aims to address.
• Cryptography provides an overview of the cryptographic building blocks that drand uses to generate publicly-verifiable, unbiased, and unpredictable randomness in a distributed manner.
• Security model describes the security considerations taken into account when designing and building drand.
• Specification is a formal description of the drand protocols.

WARNING

As of Q2'22, the drand network operated by the League of Entropy (LoE) (opens new window) is running a testnet that integrates support for multi-frequency beacons and unchained randomness. You can read all the details in this blogpost (opens new window). The documentation in this site has been updated to include mention of these features, although they are not currently supported in LoE's drand mainnet. All changes are backward compatible. We expect that mainnet will switch to unchained randomness and support for multi-frequency beacons in Q4'22.
