# orbit-db-pubsub

[![npm version](https://badge.fury.io/js/orbit-db-pubsub.svg)](https://badge.fury.io/js/orbit-db-pubsub)

Default message propagation service for [orbit-db](https://github.com/haadcode/orbit-db). Uses [IPFS](https://dist.ipfs.io/go-ipfs/floodsub-2) [pubsub](https://github.com/ipfs/go-ipfs/blob/master/core/commands/pubsub.go#L23).
