# Pubsub network
# Public endpoints
The public League Of Entropy (opens new window) network provides the following 1st-tier gossip relays (all existing gossip relays will form a mesh to distribute randomness around):
The pubsub topic on which randomness is published is based to the drand's chain hash as follows:
for the public network being
The published messages are encoded protobufs of type
PublicRandResponse (opens new window).
In order to receive randomness using this method you will need to run an application that creates a libp2p host that can connect to a pubsub relay and subscribe to the pubsub topic. We recommend using drand's client libraries or the drand-client tool, which automatically perform verification for this task.
As a side note, IPFS can be used to subscribe to pubsub topics (running with
ipfs daemon --enable-pubsub-experiment):
ipfs swarm connect /dnsaddr/api.drand.sh
ipfs pubsub sub /drand/pubsub/v0.0.0/8990e7a9aaed2ffed73dbd7092123d6f289930540d7651336225dc172e51b2ce
(note that you will only see raw protobuf as the output though).
