Types

type DrandBeacon

type DrandBeacon struct {
	// contains filtered or unexported fields
}

DrandBeacon connects Lotus with a drand network in order to provide randomness to the system in a way that's aligned with Filecoin rounds/epochs.

We connect to drand peers via their public HTTP endpoints. The peers are enumerated in the drandServers variable.

The root trust for the Drand chain is configured from build.DrandChain.
